Description

The present invention relates to an alarm system, device, setting method, and program for detecting abnormalities.

Conventionally, alarm systems have been provided that generally use wireless signals to link multiple alarm devices together. In such alarm systems, multiple alarm devices are installed in multiple locations, and when any one of the alarm devices detects a fire, that alarm device outputs an alarm and transmits information notifying the detection of the fire to the other alarm devices via wireless signal. For example, as disclosed in Patent Document 1, a specific alarm device among the alarm devices belonging to the system is designated as a parent device, and the other alarm devices are designated as child devices, so that an alarm message notifying each child device of a fire can be sent from the parent device, and this allows not only the alarm device at the source of the fire but also multiple alarm devices to link together and output an alarm, making it possible to notify the occurrence of a fire quickly and reliably.

JP 2011-133979 A

It is known that the settings between the parent unit and child units for the alarm system are made by first registering the information to be set for each of the parent unit and child units in each device, and then sharing and setting the information between the parent unit and child units. In conventional alarm systems, the user sets the installation location information for each of the parent unit and child units by performing operations on each of them, and then the parent unit and child units exchange the registered setting location information to set up the alarm system. In other words, conventional alarm systems complete the setting by storing the necessary information in each of the parent unit and child units, and then exchanging information between the parent unit and child units, which results in the problem that it takes a long time to set up the alarm system and is very time-consuming.

Therefore, the present invention was made in consideration of such problems, and aims to provide an alarm system, device, setting method, and program that can more efficiently perform the setting process for linking the parent unit and child unit.

In order to solve the above problem, an alarm system according to one aspect of the present invention is an alarm system that combines multiple devices including a first device and a second device, and links alarms between the multiple devices. The first device has a first control unit that executes a setting process to set up the link between the first device and the second device, and the second device has a second control unit that executes the setting process between the first device and the second device. In the setting process, the first control unit transmits individual setting information, which is information related to the setting of the second device, to the second device, and upon receiving the individual setting information, the second control unit configures its own device based on the individual setting information.

A device used as a first device in an alarm system according to one embodiment of the present invention stores individual setting information required for setting the second device.

A setting method according to one aspect of the present invention is a setting method for an alarm system that combines multiple devices including a first device and a second device and links alarms between the multiple devices. The first device has a first control unit that executes a setting process for setting the link between the first device and the second device, and the second device has a second control unit that executes a setting process between the first device and the second device. The setting method for the alarm system includes a transmission step in which the first control unit transmits individual setting information, which is information related to the setting of the second device, to the second device, and a setting step in which the second control unit, upon receiving the individual setting information, sets its own device based on the individual setting information.

An alarm system configuration program according to one aspect of the present invention causes a computer to execute a method for configuring an alarm system.

The present invention provides an alarm system, alarm, setting method, and program that can reduce the time and effort required for work and improve operability compared to when performing the setting process by operating each of the parent and child units.

<Basic Concept of Each Embodiment>
A basic concept common to each embodiment will be described. The alarm systems 1 to 4 according to the first to fourth embodiments are composed of a plurality of devices, and are systems in which a device that detects an abnormality shares the abnormality with other devices and notifies a user of the abnormality. The alarm systems 1 to 4 include a first device 10, 30, 50, 70 (hereinafter referred to as a parent device 10, 30, 50, 70) and a second device 20, 40, 60, 80 (hereinafter referred to as a child device 20, 40, 60, 80) that communicates with the first device 10, 30, 50, 70 to detect an abnormality. Here, the "device" is, for example, an alarm that detects an abnormality.

The alarm systems 1 to 4 according to each embodiment are applied to facility A, which is a residence, and are systems that detect fires and notify the occurrence of a fire.

The parent units 10, 30, 50, 70 and child units 20, 40, 60, 80 of the alarm systems 1 to 4 can arbitrarily select the devices to be applied. In addition, the form of communication between the parent units 10, 30, 50, 70 and child units 20, 40, 60, 80 is arbitrary, and communication means such as wireless, wired, and optical communication can be used.

The alarm systems 1 to 4 according to the embodiments aim to simplify the setting work for the parent units 10, 30, 50, 70 and the child units 20, 40, 60, 80 to function, and the alarm systems 1 to 4 are characterized in that the parent units 10, 30, 50, 70 set the child units 20, 40, 60, 80. In summary, the parent units 10, 30, 50, 70 transmit individual setting information 90 (including, for example, location information 91, re-ringing time 92, latch information 93, language information 94, and sound information 95) which is information related to the setting of the child units 20, 40, 60, 80, to the child units 20, 40, 60, 80, and the child units 20, 40, 60, 80 that receive the individual setting information 90 set their own settings based on the individual setting information 90.

This configuration minimizes the operations required for each device in order to complete the settings for the devices belonging to alarm systems 1 to 4, thereby reducing the time and effort required for the work.

As described above, the devices used as the parent unit 10 and child unit 20 in each embodiment are arbitrary, but in embodiment 1, an example is described in which the parent unit 10 and child unit 20 are applied to a wireless residential detector (hereinafter referred to as a detector) that detects a fire and notifies the occurrence of a fire. The detector is installed, for example, on the ceiling of facility A, but may also be installed on a wall.

As shown in FIG. 1, the alarm system 1 includes one parent unit 10 and three child units 20 (20A, 20B, 20C), and the child units 20 communicate with the parent unit 10. When describing common matters, the child units 20 are referred to as child units 20, and when describing each of the multiple child units 20, they are referred to as child units 20A, 20B, and 20C. The number of child units 20 is not limited to three.

<Description of the Configuration of Base Unit 10>
As shown in FIG. 2, the parent unit 10 includes a transmission/reception unit 101, a detection unit 102, an alarm unit 103, an operation input reception unit 104, a power supply unit 105, a first control unit 106 (hereinafter referred to as the control unit 106) that executes each control, and a memory unit 107.

The transmitter/receiver 101 performs wireless communication with the slave unit 20. The transmitter/receiver 101 uses, for example, a specific low-power radio in the 426 MHz band, and transmits and receives wireless signals such as a fire detection signal via an antenna 108 provided in the master unit 10.

The detection unit 102 only needs to detect the occurrence of a fire, and publicly known technology is used for this purpose. For example, the detection unit 102 may be an optical smoke detection sensor that uses diffuse reflection of light to detect a fire by detecting smoke during a fire, a heat detection sensor that detects a fire by detecting heat during a fire, a carbon monoxide detection sensor that detects a fire by detecting carbon monoxide generated by combustion during a fire, or an infrared detection sensor that detects a fire by detecting infrared rays emitted by combustion during a fire.

The alarm unit 103 issues a fire alarm through a speaker using an alarm sound or a voice message to alert the user of a fire. When the detection unit 102 of the alarm unit 103 detects a fire, or when the alarm unit 103 receives a fire detection signal transmitted by any of the child units 20, the alarm unit 103 issues an alarm sound or a voice message under the control of the control unit 106. When the alarm unit 103 issues a voice message, it is preferable that the voice message include information about the location where the parent unit 10 or child unit 20 that detected the fire is installed.

The operation input reception unit 104 has a switch 109 such as a push button or a dip switch, and when the switch 109 is operated, it receives an operation input corresponding to the switch 109 and outputs an operation signal corresponding to the operation input to the control unit 106. In the first embodiment, when the operation input reception unit 104 receives a predetermined operation input, it has a role of outputting an operation signal that causes the control unit 106 to execute a setting process described below.

The power supply unit 105 uses batteries such as dry cells as a power source to provide operating power to each component.

When the control unit 106 receives a fire detection signal from the detection unit 102, it controls the notification unit 103 to sound an alarm or a voice message, and controls the transmission/reception unit 101 to transmit a wireless signal including the fire detection signal to the slave unit 20, which is another detector. When the transmission/reception unit 101 receives a fire detection signal wirelessly transmitted from the slave unit 20 that is the source of the fire, the control unit 106 controls the notification unit 103 to sound an alarm or a voice message, and controls the transmission/reception unit 101 to transmit the fire detection signal to the slave unit 20 other than the slave unit 20 that is the source of the fire. The control unit 106 also executes a setting process related to the linkage between the master unit 10 and the slave unit 20. The setting process will be described in detail later.

The parent unit 10 is assigned a unique first identification code 96 (hereinafter, parent unit identification code 96) during the manufacturing process. The parent unit identification code 96 is stored in the memory unit 107, which will be described later. This identification code enables the child unit 20 to identify the parent unit 10 that is the destination of the wireless signal and the source of the fire detection signal, etc. The identification code is the IP address, MAC address, or name of the parent unit 10, etc.

The storage unit 107 stores the parent unit identification code 96 and the individual setting information 90, which is information required to set the child unit 20, in a data table 98. After receiving the child unit identification code 97 from the child unit 20, the storage unit 107 stores the child unit identification code 97.

As shown in FIG. 3, the individual setting information 90 includes location information 91 of the handset 20, a re-ringing time 92 of the handset 20, information 93 on whether the handset 20 is latched (hereinafter referred to as latch information 93), language information 94, and sound information 95. Note that the memory unit 107 does not need to store all of the above-mentioned information as the individual setting information 90, and it is sufficient to store only at least one piece of information. Furthermore, the individual setting information 90 is not limited to the above-mentioned information. The form in which the individual setting information 90 is stored is also not limited to the data table 98.

The location information 91 is information about the location where the handset 20 is installed, and is, for example, name information indicating the name of the floor on which it is installed. In this embodiment, the memory unit 107 stores name information such as "1st floor" and "2nd floor." By registering this location information 91 in the handset 20, the location information 91 can be included in a voice message and sounded when the handset 20 detects a fire.

The re-alarm time 92 is the time until the alarm of the handset 20 sounds again after the switch 109 of the parent unit 10 that sounds the alarm or the switch 209 of the handset 20 is operated to stop the alarm. The re-alarm time can be set, for example, from 2 to 15 minutes, and the memory unit 107 stores time information such as "2 minutes" or "3 minutes." The re-alarm time can be changed as appropriate depending on the area of the facility in which the alarm system 1 is installed, the alert area, and the use of the building.

Latch information 93 is information on whether or not the handset 20 is latched. When latched, the handset 20 continues to sound an alarm even if the parent unit 10 or the handset 20 that detected a fire stops sounding an alarm or if the fire detection signal transmitted by the parent unit 10 or the handset 20 that detected a fire is no longer received. When not latched, the handset 20 stops sounding an alarm when the parent unit 10 or the handset 20 that detected a fire stops sounding an alarm or if the fire detection signal transmitted by the parent unit 10 or the handset 20 that detected a fire is no longer received. In other words, when latched, the handset 20 continues sounding an alarm regardless of the operation or communication state of the source of the fire detection, and when not latched, the handset 20 stops sounding an alarm depending on the operation or communication state of the source of the fire detection. The memory unit 107 stores "latched" or "unlatched".

Language information 94 is information about the language of the voice message sounded by the notification unit 203 of the handset 20. Language information 94 is information corresponding to, for example, Japanese, English, Chinese, German, etc., and can be changed as appropriate to suit the language used by the user.

Sound information 95 is information about the pronunciation pattern of the alarm sound emitted by the alarm unit 203 of the handset 20. Sound information 95 is information for generating a sound pattern that complies with standards such as the international standard "ISO 8201", the German "DIN 33404-3", the British "BS 5839-1", the French "NF S32-001", and the Dutch "NEN 2575", and can be changed as appropriate to suit the country of use.

As described above, the individual setting information 90 is information related to the child unit 20, and if there are multiple child units 20, it is possible to set common individual setting information 90 for each of the child units 20A, 20B, and 20C. In this case, the parent unit 10 only needs to store one set of individual setting information 90 as shown in FIG. 3, and the parent unit 10 can transmit the individual setting information 90 to each of the child units 20A, 20B, and 20C, and the child units 20A, 20B, and 20C can configure themselves based on that information, thereby improving the efficiency of configuration.

3, if the control unit 106 of the parent unit 10 transmits individual setting information 90, which includes location information 91 "1st floor", re-ring time 92 "2 minutes", latch information 93 "latched", language information 94 "Japanese", and sound information 95 "alarm sound conforming to the international standard "ISO 8201", to each of the child units 20A, 20B, and 20C, the child units 20A, 20B, and 20C configure their own devices with location information 91 as "1st floor", re-ring time 92 as "2 minutes", latch information 93 as "latched", language information 94 as "Japanese", and sound information as "alarm sound conforming to the international standard "ISO 8201". After completing the configuration, the child units 20A, 20B, and 20C recognize that they are installed on the first floor. Furthermore, when a fire is detected, a voice message in Japanese or an alarm sound conforming to international standards is sounded to notify that a fire has broken out on the first floor. Even if the alarm is stopped by pressing switch 209, for example, it will sound again two minutes later. Furthermore, the voice message and alarm sound continue to sound even after the voice message or alarm sound of the alarm that detected the fire has stopped, or even after the fire detection signal is no longer received from the alarm that detected the fire.

The method for the parent unit 10 to store the individual setting information 90 is, for example, for the user to operate the parent unit 10 to store it. However, this is not limited to this, and the individual setting information 90 may be determined at the manufacturing stage, or the individual setting information 90 may be input using an external device 99 described in embodiment 4 below.

The individual setting information 90 set for the handset 20A, handset 20B, and handset 20C does not have to be the same. As shown in FIG. 4, the base unit 10 may have a data table 98 that stores multiple sets of individual setting information 90. The data table 98 stores multiple combinations of location information 91, re-ringing time 92, latch information 93, language information 94, and sound information 95, and the base unit 10 can select the necessary individual setting information 90 according to the target handset 20 and transmit it from the base unit 10 to the handset 20. Note that the combinations of location information 91, re-ringing time 92, latch information 93, language information 94, and sound information 95 shown in FIG. 4 are examples, and the number of combinations stored in the data table 98 can be increased or decreased.

<Description of the configuration of the child device 20>
The child unit 20 has a configuration similar to that of the parent unit 10, and as shown in FIG. 2, the child unit 20 includes a transmission/reception unit 201, a detection unit 202, an alarm unit 203, an operation input reception unit 204, a power supply unit 205, a second control unit 206 (hereinafter referred to as the control unit 206) that executes each control, and a memory unit 207.

The transmitter/receiver 201 performs wireless communication with the parent unit 10. The transmitter/receiver 201 uses, for example, a specific low-power radio in the 426 MHz band, and transmits and receives wireless signals such as a fire detection signal via an antenna 208 provided in the child unit 20.

The detection unit 202 only needs to detect the occurrence of a fire, and publicly known technology is used for this purpose. For example, the detection unit 202 is an optical smoke detection sensor that uses diffuse reflection of light to detect a fire by detecting smoke during a fire, a heat detection sensor that detects a fire by detecting heat during a fire, a carbon monoxide detection sensor that detects a fire by detecting carbon monoxide generated by combustion during a fire, or an infrared detection sensor that detects a fire by detecting infrared rays emitted by combustion during a fire.

The alarm unit 203 issues a fire alarm through a speaker using an alarm sound or a voice message to notify the user of the occurrence of a fire. When the detection unit 202 of the alarm unit 203 detects a fire, or when the alarm unit 203 receives a fire detection signal transmitted by another child unit 20 or the parent unit 10, the alarm unit 203 issues an alarm sound or a voice message under the control of the control unit 206. When the alarm unit 203 issues a voice message, it is preferable that the voice message include information about the location where the parent unit 10 or child unit 20 that detected the fire is installed.

The operation input reception unit 204 has a switch 209 such as a push button or a DIP switch, and receives an operation input corresponding to the switch 209 when the switch 209 is operated, and outputs an operation signal corresponding to the operation input to the control unit 206. In the first embodiment, when the operation input reception unit 204 receives a predetermined operation input, it has a role of outputting an operation signal that causes the control unit 206 to execute a setting process described below.

The power supply unit 205 uses batteries such as dry cells as a power source to provide operating power to each component.

When the control unit 206 receives a fire detection signal from the detection unit 202, it controls the notification unit 203 to sound an alarm or a voice message, and controls the transmission/reception unit 201 to transmit a wireless signal including a fire detection signal to notify the parent unit 10 of a fire. Furthermore, when the control unit 206 receives a fire detection signal wirelessly communicated from the parent unit 10, it controls the notification unit 203 to sound an alarm or a voice message. Furthermore, the control unit 206 executes a setting process related to the linkage between the parent unit 10 and the child unit 20. The setting process will be described in detail later.

The slave unit 20 is assigned a second identification code 97 (hereinafter referred to as the slave unit identification code 97) during the manufacturing process, and this slave unit identification code 97 enables the master unit 10 to identify the slave unit 20 that is the destination of a wireless signal and the source of a fire detection signal, etc.

Unlike the parent unit 10, the storage unit 207 stores only the child unit identification code 97. After receiving the individual setting information 90 from the parent unit 10, the storage unit 207 stores the individual setting information 90. Furthermore, after receiving the parent unit identification code 96 from the parent unit 10, the storage unit 207 stores the parent unit identification code 96.

<Explanation of setting process>
The setting process of the handset 20 in this embodiment will be described below with reference to Fig. 5 and Fig. 6. The setting process includes a synchronization setting process for synchronizing the handset 20 with the base unit 10 by having the handset 20 recognize the base unit identification code 96 of the base unit 10, and an individual setting process for storing individual setting information 90 including location information 91, re-ringing time 92, latch information 93, language information 94, and sound information 95 in the handset 20.

The synchronization setting process is completed when the parent unit 10 sends the parent unit identification code 96 to the child unit 20, the child unit 20 sends the child unit identification code 97 to the parent unit 10, and the identification numbers of each unit are stored. The individual setting process is completed when the parent unit 10 sends the individual setting information 90 to the child unit 20, and the child unit 20 completes the setting based on the individual setting information 90.

Possible methods for the setting process include a method in which the synchronous setting process and the individual setting process are performed almost simultaneously, a method in which the synchronous setting process is performed and then the individual setting process is performed, and a method in which only the individual setting process is performed without performing the synchronous setting process. However, these methods are merely examples and are not limiting.

Below, we will first explain the setting process in which the synchronous setting process and the individual setting process are performed almost simultaneously, with reference to Figure 5.

When the switch 109 is operated in the operation input reception unit 104 of the parent unit 10, the control unit 206 of the parent unit 10 transitions to a setting registration mode in which the child units 20 (20A to 20C) are configured. Also, when the switch 209 is operated in the operation input reception unit 204 of the child units 20 (20A to 20C), the control unit 206 of the child units 20 (20A to 20C) transitions to a setting reception mode in which the child units 20 (20A to 20C) are configured.

When the parent unit 10 transitions to the setting registration mode and the child units 20 (20A to 20C) transition to the setting reception mode, the control unit 106 of the parent unit 10 transmits a setting registration message including the parent unit identification code 96 and the individual setting information 90 from the transceiver unit 101 to the transceiver unit 201 of the child units 20 (20A to 20C). Here, the parent unit identification code 96 and the individual setting information 90 may be included in the same wireless signal packet, or may be sent consecutively with a slight time difference.

Next, when the control unit 206 of the handset 20 (20A to 20C) in the setting reception mode receives the setting registration message, it stores the parent unit identification code 96 and the individual setting information 90 in its own memory unit 207. Then, the control unit 206 that has stored the individual setting information 90 configures the handset 20 (20A to 20C) based on the individual setting information 90.

Then, the handset 20 (20A to 20C) receives the parent unit identification code 96 and the individual setting information 90 from the parent unit 10, and transmits a response message from the transceiver unit 201 of the handset 20 (20A to 20C) to the parent unit 10, notifying the parent unit identification code 96 that has been stored and the individual setting information 90 that has been set. Here, the response message includes the handset identification code 97 of the handset 20 (20A to 20C).

Regarding the response message, separate response messages may be sent to the parent unit 10 to inform the parent unit 10 that the parent unit identification code 96 and the individual setting information 90 have been accepted from the parent unit 10, and that the storage of the parent unit identification code 96 and the setting of the individual setting information 90 have been completed. In this case, when the parent unit identification code 96 and the individual setting information 90 are accepted from the parent unit 10, a response message indicating the completion of acceptance may be sent to the parent unit 10, and then, when the parent unit identification code 96 has been stored and the individual setting information 90 has been set, a response message indicating the completion of setting may be sent to the parent unit 10.

Furthermore, it is also possible to send a response message indicating completion of storing the parent unit identification code 96 and a response message indicating completion of setting the individual setting information 90 as separate response messages. Of course, each response message may include the child unit identification code 97 of the child unit 20 (20A to 20C).

After sending the response message, the child unit 20 (20A to 20C) ends the setting registration mode. After receiving the response message from the child unit 20 (20A to 20C), the parent unit 10 stores the child unit identification code 97 and ends the setting registration mode. At this point, the synchronization setting process and the individual setting process are completed.

The above is the basic flow of the setting process performed between the parent unit 10 and the child unit 20. By simply setting the parent unit 10 to the setting registration mode and the child unit 20 to the setting reception mode, the child unit 20 can complete its own setting.

Next, a method for performing the individual setting process after the synchronous setting process will be described with reference to FIG. 6. The parent unit 10 can also transmit the parent unit identification code 96 and the individual setting information 90 separately. The method for the parent unit 10 to switch to the setting registration mode and the child unit 20 to switch to the setting reception mode is as described above, and a description thereof will be omitted.

When the parent unit 10 transitions to the setting registration mode and the child units 20 (20A to 20C) transition to the setting reception mode, the control unit 106 of the parent unit 10 first transmits the parent unit identification code 96 from the transceiver unit 101 to the transceiver unit 201 of the child units 20 (20A to 20C).

Next, when the control unit 206 of the handset 20 (20A to 20C) in the setting reception mode receives the parent unit identification code 96, it stores the parent unit identification code 96 in the memory unit 209, receives the parent unit identification code 96, and transmits a response message from the transmission/reception unit 201 notifying that the parent unit identification code 96 has been received and stored. Here, the response message includes the child unit identification code 97 of the handset 20 (20A to 20C). Note that separate response messages may be transmitted when the parent unit identification code 96 is received and when the parent unit identification code 96 is stored.

After receiving the response message, the parent unit 10 stores the child unit identification code 97, at which point the synchronization setting process is completed. The transmitter/receiver unit 101 of the parent unit 10 then transmits the individual setting information 90 to the child units 20 (20A to 20C). When the control unit 206 of the child units 20 (20A to 20C) receives the individual setting information 90, it configures the child units 20 (20A to 20C) based on the individual setting information 90.

Then, the handset 20 (20A to 20C) receives the individual setting information 90 and transmits a response message from the transceiver 201 of the handset 20 (20A to 20C) notifying the user that the setting has been completed. At this point, the individual setting process is completed. Here, the response message may include the handset identification code 97 of the handset 20 (20A to 20C).

The response message may be sent to the parent unit 10 as separate response messages indicating that the individual setting information 90 has been accepted and that the setting has been completed. In this case, when the individual setting information 90 is accepted from the parent unit 10, a response message indicating that acceptance has been completed may be sent to the parent unit 10, and when the individual setting information 90 is set, a response message indicating that setting has been completed may be sent to the parent unit 10. Of course, either of the response messages may include the child unit identification code 97 of the child unit 20 (20A to 20C).

Then, after sending the response message, the child device 20 (20A to 20C) ends the setting reception mode, and after receiving the response message from the parent device 10, the parent device 10 ends the setting registration mode.

It is also possible to perform only the individual setting process without performing the synchronous setting process. In this case, after the parent unit 10 transitions to the setting registration mode and the child unit 20 transitions to the setting reception mode, the transceiver unit 101 of the parent unit 10 transmits the individual setting information 90 to the child unit 20 (20A to 20C). Upon receiving the individual setting information 90, the control unit 206 of the child unit 20 (20A to 20C) configures the child unit 20 (20A to 20C) based on the individual setting information 90.

Then, the handset 20 (20A to 20C) receives the individual setting information 90 and transmits a response message from the transceiver 201 of the handset 20 (20A to 20C) notifying the user that the setting has been completed. At this point, the individual setting process is completed. Here, the response message may include the handset identification code 97 of the handset 20 (20A to 20C).

The response message may be sent to the parent unit 10 as separate response messages indicating that the individual setting information 90 has been accepted and that the setting has been completed. In this case, when the individual setting information 90 is accepted from the parent unit 10, a response message indicating that acceptance has been completed may be sent to the parent unit 10, and when the individual setting information 90 is set, a response message indicating that setting has been completed may be sent to the parent unit 10. Of course, either of the response messages may include the child unit identification code 97 of the child unit 20 (20A to 20C).

Then, after sending the response message, the child device 20 (20A to 20C) ends the setting reception mode, and after receiving the response message from the child device 20 (20A to 20C), the parent device 10 ends the setting registration mode.

Note that other methods can be used for the parent unit 10 to switch to the setting registration mode and the child unit 20 to switch to the setting reception mode. For example, in the above method, the transition to each mode was performed by operating switch 109 of the parent unit 10 and switch 209 of the child unit 20. However, a method can be considered in which, if the parent unit 10 and child unit 20 are powered on for a certain period of time (e.g., 5 minutes), the parent unit 10 switches to the setting registration mode when the power is turned on, and the child units 20 (20A to 20C) switch to the setting reception mode when the power is turned on, without operating either switch 109 or switch 209. Note that the period of the setting registration mode is not limited to the above period.

It is also possible to consider a method in which when switch 109 or switch 209 is pressed on a parent unit 10 and a child unit 20 that are powered on, all parent units 10 and child units 20 that are powered on automatically switch to the setting registration mode or the setting reception mode.

Furthermore, in order to allow each to recognize that it has switched to the setting registration mode or the setting reception mode, it is also possible that a signal indicating that it has switched to the setting registration mode is output from the parent unit 10 to the child unit 20, and a signal indicating that it has switched to the setting reception mode is output from the child unit 20 to the parent unit 10.

In this way, by limiting the period during which settings can be registered, it is possible to prevent alarm devices that do not belong to the alarm system 1 of this embodiment from being mistakenly registered.

As shown in FIG. 5, when there are multiple child devices 20 and multiple child devices 20 have transitioned to the setting reception mode, it is possible to move on to child devices 20B and 20C when processing is completed in child device 20A. In this case, when parent device 10 receives a response message from child device 20A informing that storage of parent device identification code 96 and setting of individual setting information 90 have been completed, parent device 10 sends a setting registration message including parent device identification code 96 and individual setting information 90 to another child device, for example child device 20B, and starts the setting process. It is also possible that parent device 10 sends a setting registration message to child device 20B and starts the setting process without waiting for a response message from child device 20A.

Even if individual setting processing is performed after the synchronous setting processing as shown in FIG. 6, when transmitting at least one of the parent unit identification code 96 and the individual setting information 90, a method of transmitting the information at different timings for each of the child units 20A, 20B, and 20C and proceeding with the setting of each child unit 20 can be considered.

However, for example, it is possible to leave the parent unit identification code 96 set in the child units 20 (20A to 20C) as is, and only modify the individual setting information 90 (hereinafter referred to as the resetting process). In this case, the individual setting information 90 stored in the parent unit 10 must be erased once, the parent unit 10 must store the modified individual setting information 90, and then the information must be set again in the child units 20 (20A to 20C). The resetting process in this embodiment will be described below. Note that the following description is based on the assumption that the parent unit 10 and the child units 20 have already completed sending and receiving their respective identification codes.

First, the parent device 10 belonging to the existing system transitions to a reconfiguration registration mode by operating switch 109, and the child devices 20 (20A to 20C) transition to a reconfiguration reception mode by operating switch 209. Note that in the reconfiguration process, the parent device 10 may transition to the reconfiguration registration mode and the child device 20 to the reconfiguration reception mode by operating switch 109 of any one device (here, parent device 10).

When the parent unit 10 transitions to the reconfiguration registration mode and the child units 20 (20A-20C) transition to the reconfiguration reception mode, the control unit 106 of the parent unit 10 transmits a reconfiguration registration message including new individual setting information 90 to the child units 20 (20A-20C) belonging to the system. Then, when the control unit 206 of the child units 20 (20A-20C) receives the reconfiguration registration message, it stores the new individual setting information 90 and transmits a response message to the parent unit 10 from the transmission/reception unit 201 to notify that the setting has been completed. In this case, too, the response message to be transmitted to the parent unit 10 after the new individual setting information 90 has been received may be transmitted to the parent unit 10 as separate response messages indicating that the new individual setting information 90 has been received and that the setting has been completed. In this case, when new individual setting information 90 is accepted from parent unit 10, a response message indicating acceptance completion is sent to parent unit 10, and when the new individual setting information 90 is set, a response message indicating setting completion is sent to parent unit 10.

Also, as shown in FIG. 7, if there are multiple child devices 20 belonging to the system, it is possible to send a reconfiguration registration message including new individual setting information 90 by multicast to child devices 20A, 20B, and 20C.

By simultaneously transmitting the individual setting information 90 from the parent device 10 to the child devices 20A, 20B, and 20C by multicast, the reconfiguration process can be shortened compared to transmitting the individual setting information 90 from the parent device 10 to the child devices 20A, 20B, and 20C in sequence.

As described above, in the first embodiment, the parent unit 10 transmits the individual setting information 90 stored therein to the child unit 20, so that the child unit 20 stores the individual setting information 90. The control unit 206 of the child unit 20 can configure the child unit 20 based on the individual setting information 90. In other words, the parent unit 10 stores the individual setting information 90 common to the multiple child units 20 in advance, and the multiple child units 20 can be configured at once by transmitting the individual setting information 90 to the child unit 20. Therefore, the alarm system 1 according to this embodiment can simplify the work required for configuration and shorten the time required for registration, compared to the case where the parent unit 10 and the child unit 20 are operated one by one, the information required for configuration is stored, and then the parent unit 10 and the child unit 20 exchange the stored information and perform the configuration process.

(Embodiment 2)
＜Overview＞
The alarm system 2 according to the second embodiment will be described with reference to Fig. 8 and Fig. 9. Fig. 8 is a block diagram showing the master unit 30 and the slave unit 40, and Fig. 9 is an explanatory diagram showing the alarm system 2 arranged in a building A having a hierarchical structure.

As mentioned above, the devices used as the parent unit 30 and child unit 40 in each embodiment are arbitrary, but in embodiment 2, an example will be described in which the parent unit 30 is a repeater and the child unit 40 is a wireless residential sensor (hereafter referred to as a sensor). A repeater here is assumed to be a device that wirelessly exchanges signals with other repeaters. Since embodiment 2 is similar to the alarm system 1 of embodiment 1 except that the parent unit 30 is a repeater, a description of the commonalities will be omitted.

9, the alarm system 2 includes a parent unit 30 (30A, 30B) and a total of six child units 40 (40A, 40B, 40C, 40D, 40E, 40F), three connected to the parent unit 30A and three connected to the parent unit 30B. The child units 40A to 40C perform wireless communication with the parent unit 30A, and the child units 40D to 40F perform wireless communication with the parent unit 30B. Wireless communication is also performed between the parent unit 30A and the parent unit 30B. As a result, for example, when the child unit 40A detects the occurrence of a fire, a fire detection signal indicating the occurrence of a fire is transmitted to the parent unit 30A, and the parent unit 30A executes a fire alarm. Also, a fire detection signal is transmitted via the parent unit 30B to the child unit 40D, and the child unit 40D executes a fire alarm. As a result, the detection result is shared among the multiple child units 40, and the multiple child units 40 execute a fire alarm in cooperation with each other.

When describing common matters, the child unit 40 will be referred to as child unit 40, and when describing multiple child units 40, they will be referred to as child units 40A to 40F. Here, the number of parent units 30 is not limited to two, and the number of child units 40 is not limited to six.

<Description of the configuration of the parent unit 30>
As shown in FIG. 8, the parent unit 30 includes a first transceiver unit 301, a second transceiver unit 302, an alarm unit 303, an operation input receiving unit 304, a power supply unit 305, a first control unit 306 (hereinafter referred to as the control unit 306), and a memory unit 307.

The first transceiver 301 uses a channel frequency f corresponding to the group to which the first transceiver 301 belongs, and performs wireless communication with a slave unit 40 that belongs to the same group. The first transceiver 301 uses, for example, a specific low-power radio in the 426 MHz band, and transmits and receives wireless signals such as a fire detection signal via a first antenna 308 provided on the master unit 30.

The second transceiver 302 transmits and receives signals such as fire detection signals between adjacent parent units 30 via a second antenna 309 provided in the parent unit 30. As with the first transceiver 301, a specific low-power radio in the 426 MHz band is used, for example.

The alarm unit 303 alerts the user to the occurrence of a fire by sounding a fire alarm through a speaker using an alarm sound or a voice message. When the alarm unit 303 receives a fire detection signal transmitted by the handset 40, it sounds an alarm sound or a voice message under the control of the control unit 306. When the alarm unit 303 sounds a voice message, it is preferable that the voice message include information about the location where the handset 40 that detected the fire is installed.

The operation input reception unit 304 has a switch 310 such as a push button or a dip switch, and when the switch 310 is operated, it receives an operation input corresponding to the switch 310 and outputs an operation signal corresponding to the operation input to the control unit 306. In the second embodiment, when the operation input reception unit 304 receives a predetermined operation input, it has a role of outputting an operation signal that causes the control unit 306 to execute a setting process.

The power supply unit 305 uses batteries such as dry cells as a power source to provide operating power to each component.

When the control unit 306 receives a fire detection signal wirelessly transmitted from the child device 40 that is the source of the fire at the first transmission/reception unit 301, the control unit 306 controls the notification unit 303 to sound an alarm. When the control unit 306 receives a fire detection signal from a child device 40 that belongs to the same group, the control unit 306 controls the second transmission/reception unit 302 to transmit a fire detection signal to another adjacent parent device 30, and controls the first transmission/reception unit 301 to transmit a fire detection signal to a child device 40 other than the child device 40 that is the source of the fire in the same group. When the control unit 306 receives a fire detection signal from another parent device 30, the control unit 306 controls the notification unit 303 to sound an alarm, and controls the first transmission/reception unit 301 to transmit a fire detection signal to a child device 40 that belongs to the same group. The control unit 306 also executes a setting process that is a setting related to the linkage between the parent device 10 and the child device 20.

The storage unit 307 stores a unique parent unit identification code 96 and individual setting information 90, which is information required to set the child unit 40. The parent unit identification code 96 is stored in the storage unit 307 during manufacturing. The child unit 40 can identify the parent unit 30 that is the destination of the wireless signal and the source of the fire detection signal, etc., using this parent unit identification code 96. The parent unit identification code 96 is the IP address, MAC address, or name of the parent unit 30. The individual setting information 90 is stored, for example, by a user operating the parent unit 30. However, without being limited to this, the individual setting information 90 may be determined during manufacturing, or the individual setting information 90 may be input using an external device 99 described in embodiment 4 below.

<Description of the configuration of child device 40>
Next, the configuration of the slave unit 40, which is a detector, will be described. As shown in Fig. 8, the slave unit 40 includes a transmission/reception unit 401 that transmits and receives a radio signal using radio waves as a medium via an antenna 408, a detection unit 402 that detects smoke, etc., a notification unit 403 that notifies a user of a fire by sounding an alarm or a voice message, an operation input reception unit 404 that has a switch 409 and executes a setting process or an alarm stop process when a predetermined operation input is received, a power supply unit 405 that provides operating power to each unit, and a second control unit 406 (hereinafter, control unit 406) that controls each unit with a memory unit 407 as the main component. As described above, the slave unit 40 has the same configuration and functions as the slave unit 20, so detailed description of each unit will be omitted.

<Explanation of setting process>
The setting process includes a synchronization setting process for synchronizing the master unit 30 and the slave unit 40, and an individual setting process for storing individual setting information 90 including location information 91, re-ringing time 92, latch information 93, language information 94, and sound information 95 in the slave unit 40. In the setting process of this embodiment, when the operation input receiving unit 304 of the master unit 30 is operated, the control unit 106 of the master unit 10 transitions to a setting registration mode for setting the slave unit 20, and starts the setting process. The specific method is similar to the setting process method of the alarm system 1 according to the first embodiment, and therefore a description thereof will be omitted.

<Explanation of system configuration across hierarchical levels>
The alarm system 2 described above may be used, for example, as shown in Fig. 9. The alarm system 2 is installed, for example, in a two-story building A, and one parent unit 30 (30A, 30B) functioning as a repeater and three child units 40 (40A to 40F) functioning as sensors are arranged on each floor.

Here, one parent unit 30 and three child units 40 installed on each of the first and second floors form a group for each floor, with group 1 (G1) on the first floor and group 2 (G2) on the second floor. A different channel frequency f (f1, f2) is assigned to each of groups G1 and G2, and devices belonging to each group transmit and receive signals using the channel frequency f assigned to their own group. When a child unit 40 installed in groups G1 and G2 detects a fire, it sounds an alarm and transmits a fire detection signal to the parent unit 30 belonging to its own group.

In addition, the parent unit 30, which is a repeater, is connected to the adjacent parent unit 30 so that it can communicate wirelessly. In other words, the parent unit 30 plays a role of relaying between groups set for each floor. For example, if a fire occurs on the first floor, one of the child units 40 (40A to 40C) installed in group G1 detects the fire, and the child units 40 (40A to 40C) installed in group G1 transmit a fire detection signal to the parent unit 30A using channel frequency f1. When the parent unit 30A receives the fire communication signal, it sounds an alarm by itself and transmits a fire detection signal to the parent unit 30B of the adjacent group G2. After receiving the fire detection signal, the parent unit 30B of group G2 sounds an alarm by itself and transmits a fire detection signal to the child units 40 (40D to 40F) installed in group G2. The slave units 40 (40D-40F) that receive the fire detection signal will sound an alarm.

In this way, even if a fire is detected by a handset 40 belonging to one of the groups, a linked alarm is sounded by the handset 40 on other floors via the parent unit 30, so that it is possible to reliably notify users in building A of the fire and encourage them to take action, such as evacuation.

In the case of a system configuration spanning hierarchical levels as shown in FIG. 9, the setting process is performed for each group G1, G2. That is, the parent unit 30 of each group transmits the individual setting information 90 stored therein to the child units 40 belonging to the same group, and the child units 40 store the individual setting information 90. The control unit 406 of the child unit 40 then configures its own unit based on the individual setting information 90 transmitted by the parent unit 10 belonging to its own group. At this time, it is assumed that the individual setting information 90 stored in the parent units 30 of each group is different for each parent unit 30. However, this is not limited to the above, and all parent units 30 may store the same individual setting information 90.

As described above, in the second embodiment, the parent unit 30 is a repeater, but the same effect as in the first embodiment can be obtained even if the parent unit 30 is replaced with various commercial products. In other words, the parent unit 30 can transmit the individual setting information 90 stored therein to the child unit 40, and the child unit 40 can configure itself based on the individual setting information 90. Therefore, compared to operating the parent unit 30 and the child unit 40 one by one, storing the information required for configuration, and then exchanging the stored information between the parent unit 30 and the child unit 40 to perform the configuration process, the work required for configuration can be simplified and the time required for registration can be shortened.

(Embodiment 3)
＜Overview＞
The alarm system 3 according to the third embodiment will be described with reference to Fig. 10 and Fig. 11. Fig. 10 is a block diagram showing a master unit 50 and a slave unit 60, and Fig. 11 is an explanatory diagram showing the alarm system 3 arranged in a building with a hierarchical structure.

As mentioned above, the devices used as the parent unit 50 and child unit 60 in each embodiment are arbitrary, but in embodiment 3, an example will be described in which the parent unit 50 is a repeater receiver and the child unit 60 is a wireless residential sensor (hereafter referred to as a sensor). The repeater receiver here is assumed to be a device that exchanges signals between the same devices via a wire. Since embodiment 3 is similar to the alarm system of embodiment 1 except for the parent unit 50 being a repeater receiver, a description of the commonalities will be omitted.

As shown in FIG. 11, the alarm system 3 includes a parent unit 50 (50A, 50B, 50C) and a total of nine child units 60 (60A, 60B, 60C, 60D, 60E, 60F, 60G, 60H, 60I), three connected to parent unit 50A, three to parent unit 50B, and three to parent unit 50C. The child units 60A-60C perform wireless communication with the parent unit 50A, the child units 60D-60F perform wireless communication with the parent unit 50B, and the child units 60G-60I perform wireless communication with the parent unit 50C. In addition, wired communication is performed between the parent unit 50A, the parent unit 50B, and the parent unit 50C. As a result, for example, if the child unit 60A detects the occurrence of a fire, a fire detection signal indicating the occurrence of a fire is transmitted to the parent unit 50A, and the parent unit 50A executes a fire alarm. In addition, a fire detection signal is sent to the slave unit 60D via the master unit 50B, and the slave unit 60D issues a fire alarm. As a result, the detection result is shared among the slave units 60, and the slave units 60 issue a fire alarm in unison.

When describing common matters, the child unit 60 will be described as a child unit 60, and when describing multiple child units 60, they will be described as child units 60A to 60I. Here, the number of parent units 50 is not limited to three, and the number of child units 60 is not limited to nine.

<Description of the Configuration of Parent Unit 50>
As shown in FIG. 10 , the parent unit 50 includes a wireless transceiver unit 501, a wired transceiver unit 502, an operation unit 503, an alarm unit 504, a display unit 505, an operation input reception unit 506, a power supply unit 507, an indicator light 508, a first control unit 509 (hereinafter referred to as the control unit 509) that executes each control, and a memory unit 510.

The wireless transmission/reception unit 501 uses a channel frequency f corresponding to the group to which the wireless device belongs, and performs wireless communication with the child devices 60 that belong to the same group. The wireless transmission/reception unit 501 uses, for example, a specific low-power radio in the 426 MHz band, and transmits and receives wireless signals such as a fire detection signal via an antenna 511 provided in the parent device 50.

The wired transceiver unit 502 transmits and receives signals such as fire detection signals between adjacent parent units 50 via the communication line 512 provided in the parent unit 50.

The operation unit 503 is a push switch that receives a push operation from a user using the building in the event of a fire in building A. When the operation unit 503 receives a push operation, an alarm sound is generated from the notification unit 504, which will be described later.

The alarm unit 504 sounds a fire alarm such as an alarm sound or a voice message from the speaker to notify the user of the occurrence of a fire. When the operation unit 503 accepts a press operation in the event of a fire occurrence, or when the alarm unit 504 receives a fire detection signal transmitted by the handset 60, the alarm unit 504 sounds an alarm sound or a voice message under the control of the control unit 509. When the alarm unit 504 sounds a voice message, it is preferable that the voice message include location information about the location of the device that detected the fire.

The display unit 505 displays the occurrence of a fire, etc. The display unit 505 is composed of, for example, a liquid crystal display, and when the operation unit 503 accepts a press operation in the event of a fire, or when a fire detection signal sent by the handset 60 is received, the display unit 505 displays text information to notify of a fire under the control of the control unit 509. The text information may be, for example, "A fire has occurred," or may convey location information such as "A fire has occurred on the first floor." The display unit 505 may also display text information such as "Operation is normal" or "Operation is abnormal" depending on the results of an operation inspection.

The operation input reception unit 506 has switches 513 such as push buttons or dip switches, and receives operation input corresponding to each switch 513 by operating the switches 513, and outputs an operation signal corresponding to the operation input to the control unit 509. In this embodiment, the operation input reception unit 506 is provided with a setting switch 513 that outputs an operation signal that causes the control unit 509 to execute a setting process when it receives a predetermined operation input.

The power supply unit 507 converts commercial AC 100V into DC power and is equipped with a battery as a backup power source if necessary.

The indicator light 508 has, for example, an LED and a dome-shaped cover that covers the front of the LED. The cover is translucent. The indicator light 508 is always lit so that the position of the parent unit 50 can be clearly indicated even in the dark.

The control unit 509 receives a fire detection signal wirelessly transmitted from the child unit 60 of the fire source via the wireless transceiver unit 501, controls the alarm unit 504 to sound an alarm, and controls the display unit 505 to display the occurrence of a fire.

When the control unit 509 receives a fire detection signal, it transmits the fire detection signal from the wired transceiver unit 502 to other adjacent parent units 50. When the control unit 509 receives a fire detection signal from another parent unit 50, it controls the alarm unit 504 to sound an alarm or a voice message, and controls the display unit 505 to display the occurrence of a fire. It then controls the wireless transceiver unit 501 to transmit the fire detection signal to the child units 60 that belong to the same group. The control unit 509 also executes a setting process that is related to the linkage between the parent unit 10 and the child units 20.

The storage unit 510 stores the parent unit identification code 96 and the individual setting information 90, which is information required to set up the child unit 60. The storage unit 510 also stores the child unit identification code 97 after receiving the child unit identification code 97 from the child unit 60.

The parent unit identification code 96 is stored in the memory unit 510 during manufacturing. This parent unit identification code 96 allows the child unit 60 to identify the parent unit 50 that is the destination of the wireless signal and the source of the fire detection signal, etc. The parent unit identification code 96 is the IP address, MAC address, or name of the parent unit 50. The individual setting information 90 is stored, for example, by the user operating the parent unit 50. However, without being limited to this, the individual setting information 90 may be determined during manufacturing, or the individual setting information 90 may be input using an external device 99 described in embodiment 4 below.

<Description of the configuration of the child device 60>
Next, the configuration of the slave unit 60, which is a detector, will be described. As shown in Fig. 10, the slave unit 60 includes a transmission/reception unit 601 that transmits and receives a radio signal using radio waves as a medium via an antenna 608, a detection unit 602 that detects smoke, etc., a notification unit 603 that notifies a user of a fire by sounding an alarm or a voice message, an operation input reception unit 604 that has a switch 609 and executes a setting process or an alarm stop process when a predetermined operation input is received, a power supply unit 605 that provides operating power to each unit, and a second control unit 606 (hereinafter, control unit 606) that controls each unit and has a memory unit 607 as its main component. As described above, the slave unit 60 has the same configuration and functions as the slave unit 20, so detailed descriptions of each unit will be omitted.

<Explanation of setting process>
The setting process includes a synchronization setting process for synchronizing the parent unit 50 and the child unit 60, and an individual setting process for storing individual setting information 90, including location information 91, re-ringing time 92, latch information 93, language information 94, and sound information 95, in the child unit 40. In the setting process of this embodiment, when the operation input acceptance unit 506 of the parent unit 50 is operated, the control unit 509 of the parent unit 50 transitions to a setting registration mode for setting the child unit 20, and starts the setting process. The specific method is similar to the setting process method of the alarm system 1 according to the first embodiment, and therefore a description thereof will be omitted.

<Explanation of system configuration across hierarchical levels>
The one group of systems described above may be used, for example, in the system configuration shown in Fig. 11. The alarm system 3 is installed, for example, in a three-story building A, and on each floor there is one parent unit 50 (50A, 50B, 50C) functioning as a repeater receiver and three child units 60 (60A to 60I) functioning as sensors.

Here, one parent unit 50 and three child units 60 installed on the first to third floors each form a group, with group 1 (G1) on the first floor, group 2 (G2) on the second floor, and group G3 on the third floor. A different channel frequency f (f1, f2, f3) is assigned to each of groups G1, G2, and G3, and devices belonging to each group transmit and receive signals using the channel frequency f assigned to their own group. When a child unit 60 installed in groups G1, G2, or G3 detects a fire, it sounds an alarm and transmits a fire detection signal to the parent unit 50 belonging to its own group.

The parent unit 50, which is a repeater receiver, is connected to adjacent parent units 50 via wires so that they can communicate with each other. In other words, the parent unit 50 plays the role of relaying between groups set for each floor. Therefore, as in the second embodiment, even if a child unit 60 belonging to one of the groups detects a fire, a linked alarm is sounded by the child units 60 on other floors via the parent unit 50, so that a fire alarm can be reliably sounded to users in building A to urge them to take action, such as evacuating.

In the case of a system configuration spanning hierarchical levels as shown in FIG. 11, the setting process is performed for each group G1, G2, and G3, as in the second embodiment. That is, the parent unit 50 of each group transmits the individual setting information 90 stored therein to the child units 60 belonging to the same group, so that the child units 60 store the individual setting information 90. The control unit 606 of the child unit 60 then configures its own unit based on the individual setting information 90. At this time, it is assumed that the individual setting information 90 stored in the parent units 50 of each group is different for each parent unit 50. However, this is not limited to the above, and all parent units 50 may store the same individual setting information 90.

As described above, in the third embodiment, the parent unit 50 is a repeater receiver, but the same effect as in the first embodiment can be obtained even if the parent unit 50 is replaced with various commercial products. In other words, the parent unit 50 can transmit the individual setting information 90 stored therein to the child unit 60, and the child unit 60 can configure itself based on the individual setting information 90. Therefore, compared to operating the parent unit 50 and the child unit 60 one by one, storing the information required for configuration, and then exchanging the stored information between the parent unit 50 and the child unit 60 to perform the configuration process, the work required for configuration can be simplified and the time required for registration can be shortened.

As described above, if the device that will become the parent device stores the individual setting information for the child device, then no matter which device becomes the parent device, the child device will be able to respond to whichever parent device becomes the parent device by sending the individual setting information stored in the parent device to the child device, and the child device will be able to configure its own individual settings.

(Embodiment 4)
＜Overview＞
An alarm system 4 according to the fourth embodiment will be described with reference to Fig. 12 and Fig. 13. Fig. 12 is a schematic diagram showing the alarm system 4, and Fig. 13 is a block diagram showing a master unit 70 and a slave unit 80.

As mentioned above, the devices used as the parent unit 70 and child unit 80 in each embodiment are arbitrary, but in embodiment 4, an example will be described in which the parent unit 70 is a relay device and the child unit 80 is a wireless residential sensor (hereinafter referred to as a sensor). The relay device here is assumed to be a device composed of a first relay device 70A and a second relay device 70B, each of which is connected to one or more child units 80. This embodiment is similar to the alarm system of embodiment 1 except that the parent unit 70 is a relay device and that it is equipped with an external device 99, so a description of the common points will be omitted.

As shown in FIG. 12, the alarm system 4 includes an external device 99, one parent device 70 consisting of a first relay device 70A and a second relay device 70B, and a total of six child devices 80 (80A, 80B, 80C, 80D, 80E, 80F), three connected to the first relay device 70A and three connected to the second relay device 70B. The child devices 80A to 80C perform wireless communication with the first relay device 70A, and the child devices 80D to 80F perform wireless communication with the second relay device 70B. The first relay device 70A and the second relay device perform wired communication.

In addition, multiple first relay devices 70A may be connected to the external device 99, and multiple second relay devices 70B may be connected to the first relay device 70A.

The external device 99 is, for example, a mobile terminal or a personal computer. The external device 99 is connected to the first relay device 70A, and performs wired or wireless communication with the first relay device 70A. In other words, the external device 99 can communicate directly with the first relay device 70A, and can communicate with the second relay device 70B via the first relay device 70A, as well as with the child devices 80 (80D to 80F) connected to the second relay device 70B.

As a result, for example, when the slave unit 80A detects the occurrence of a fire, a fire detection signal indicating the occurrence of a fire is transmitted to the second relay unit 70B via the first relay unit 70A, and is then transmitted from the second relay unit 70B to the slave unit 80D, which then issues a fire alarm. As a result, the detection result is shared among the multiple slave units 80, and the multiple slave units 80 issue a fire alarm in cooperation with each other. The first relay unit 70A also transmits a fire detection signal to the external device 99. The external device 99 may manage the detection result and may display the detection result on a display (not shown) of the external device 99. The external device 99 may also control the operation of the second relay unit 70B and the slave unit 80 via the first relay unit 70A.

When describing common matters, the child device 80 will be referred to as the child device 80, and when describing each of the multiple child devices 80, they will be referred to as child devices 80A to 80F. The number of child devices 80 is not limited to six.

<Description of the Configuration of Parent Unit 70>
The first relay device 70A constituting the parent unit 70 includes, as shown in FIG. 15, a first transceiver unit 701, a second transceiver unit 702, a wired transceiver unit 703, a power supply unit 704, an operation input receiving unit 705, a first control unit 706 (hereinafter referred to as the control unit 706), and a memory unit 707.

The first transceiver 701 performs wireless communication with the handset 80. The first transceiver 701 uses, for example, a specific low-power radio in the 426 MHz band, and transmits and receives wireless signals such as a fire detection signal via a first antenna 708 provided on the first relay device 70A.

The second transceiver 702 performs wireless communication with, for example, the external device 99. The second transceiver 702 uses, for example, 920 MHz wireless communication conforming to the Wi-SUN (registered trademark) standard (international standard IEEE 802.15.4g), and transmits and receives wireless signals such as a fire detection signal via the second antenna 709 provided in the first relay device 70A. However, this is not limited to this, and wired communication may also be performed.

The wired transceiver 703 performs wired communication with the second relay device 70B, and transmits and receives signals such as a fire detection signal via a communication line 710 connected to the first relay device 70A.

The power supply unit 704 converts commercial AC 100V into DC power and is equipped with a battery as a backup power source if necessary.

The operation input reception unit 705 has a switch 711 such as a push button or a DIP switch, and when the switch 711 is operated, it receives an operation input corresponding to the switch 711 and outputs an operation signal corresponding to the operation input to the control unit 706. In the fourth embodiment, the operation input reception unit 705 has a role of outputting an operation signal that causes the control unit 706 to execute a setting process when it receives a predetermined operation input. Note that the parent unit 70 does not need to have the operation input reception unit 705, and in that case, it is considered that the setting process is executed at the timing when the external device 99 is operated, or when the parent unit 70 receives the individual setting information 90 from the external device 99.

When the control unit 706 receives a fire detection signal wirelessly transmitted from the child device 80 at the first transmission/reception unit 701, the control unit 706 controls the first transmission/reception unit 701 to transmit a fire detection signal to a child device 80 other than the child device 80 at the source of the fire. Also, when the control unit 706 receives a fire detection signal, the control unit 706 transmits a fire detection signal from the wired transmission/reception unit 703 to the second relay device 70B. When the second relay device 70B receives a fire detection signal from the first relay device 70A, the control unit 706 controls the first transmission/reception unit (not shown) of the second relay device to transmit a fire detection signal to the child device 80 with which it can communicate. Also, when the control unit 706 receives a fire detection signal, it transmits a fire detection signal to the external device 99. Also, the control unit 706 executes a setting process that is a setting related to the linkage between the parent device 10 and the child device 20.

The storage unit 707 stores the parent unit identification code 96 and the individual setting information 90, which is information required to set up the child unit 80. In addition, the storage unit 707 stores the child unit identification code 97 after receiving the child unit identification code 97 from the child unit 80.

The parent unit identification code 96 is stored in the memory unit 707 during manufacturing. This parent unit identification code 96 enables the child unit 80 to identify the destination of the wireless signal and the parent unit 50 that is the sender of a fire detection signal or the like. The parent unit identification code 96 is the IP address, MAC address, or name of the parent unit 70, for example. The individual setting information 90 is stored by the user operating the external device 99, as will be described in detail later.

The second relay device 70B is not directly connected to the external device 99 and therefore does not have the second transceiver unit 702 of the first relay device 70A. However, other configurations are the same and therefore will not be described.

<Description of the configuration of the child device 80>
As shown in FIG. 13 , the slave unit 80 includes a transmission/reception unit 801 that transmits and receives wireless signals using radio waves as a medium via an antenna 808, a detection unit 802 that detects smoke, etc., an alarm unit 803 that alerts the user to a fire by sounding an alarm or a voice message, an operation input reception unit 804 that has a switch 809 and executes setting processing or alarm stop processing when a predetermined operation input is received, a power supply unit 805 that provides operating power to each unit, and a memory unit 807 (the main component of which is a second control unit 806 (hereinafter, control unit 806) that controls each unit. As described above, the slave unit 80 has the same configuration and functions as the slave unit 20, and therefore detailed explanations of each unit will be omitted.

<Explanation of setting process>
The setting process includes a synchronization setting process for synchronizing the parent unit 70 and the child unit 80, and an individual setting process for storing individual setting information 90 including location information 91, re-ringing time 92, latch information 93, language information 94, and sound information 95 in the child unit 80. In the setting process of the fourth embodiment, first, the individual setting information is transmitted from the external device 99 to the parent unit 70, and after the parent unit 70 stores the individual setting information, the setting process of the parent unit 70 and the child unit 80 is started.

As described above, the external device 99 can communicate directly with the first relay device 70A. The external device 99 can also communicate with the second relay device 70B via the first relay device 70A. In other words, the external device 99 can control the operation of the parent device 70 via the first relay device 70A, and more specifically, can cause the parent device 70 to store the individual setting information 90 by causing the parent device 70 to transmit the individual setting information 90.

First, the user operates the external device 99 to specify individual setting information 90 including location information 91, re-ring time 92, latch information 93, language information 94, and sound information 95. The individual setting information 90 specified by the external device 99 is then sent to the first relay device 70A, whereby the individual setting information 90 is stored in the memory unit 707 of the first relay device 70A. In addition, the first relay device 70A sends the individual setting information 90 to the second relay device 70B via the wired transceiver unit 703, whereby the second relay device 70B can store the individual setting information 90.

When the parent unit 70 stores the individual setting information 90, the setting process for the child unit 80 can start. When the external device 99 is operated, the control unit 706 of the parent unit 70 transitions to a setting registration mode for setting the child unit 80 and starts the setting process. The specific method is similar to the setting process method of the alarm system 1 according to the first embodiment, and therefore a description thereof will be omitted.

In addition, the external device 99 can send the child device identification code 97 of the child device 80 to the parent device 70, thereby allowing the parent device 70 to recognize the child device 80 that will execute the setting process. In other words, the parent device 70 transmits individual setting information 90 only to the child device 80 that matches the child device identification code 97 received from the external device 99, and executes the setting process for the child device 80.

As described above, in the fourth embodiment, the external device 99 can set the details of the individual setting information 90 related to the settings of the child device 80. In addition, the individual setting information 90 can be transmitted to the parent device 70, and the child device 80 can ultimately store the individual setting information 90. In other words, since the settings of multiple child devices 80 can be performed collectively by operating the external device 99, the alarm system 4 according to the fourth embodiment can simplify the work required for setting and shorten the time required for registration, compared to the case where the parent device 70 and the child device 80 are operated one by one, the information required for setting is stored, and then the stored information is exchanged between the parent device 70 and the child device 80 to perform the setting process.

In the above embodiment, the switches 109, 209, 310, 409, 513, 609, and 809 may not only perform the role of executing the setting process, but may also perform the role of an alarm stop process for stopping a fire alarm, an inspection process for inspecting equipment, and the like. In this way, the number of switches can be reduced by having one switch 109, 209, 310, 409, 513, 609, and 809 serve to receive multiple operation inputs.

In the above embodiment, the storage units 107, 207, 307, 407, 510, 607, 707, and 807 store the control programs that the control units 106, 206, 306, 406, 509, 606, 705, and 806 execute. The control programs may be implemented by having a processing device such as a CPU (Central Processing Unit) execute the programs, that is, by software, or by hardware such as an IC (Integrated Circuit), or by a combination of software and hardware. The control programs may also be recorded in a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a DVD (Digital Versatile Disk) in an installable or executable format file. Furthermore, this control program may be stored on a computer connected to a network such as the Internet and provided by downloading it via the network, or it may be provided or distributed via a network such as the Internet.

The external device 99 of the fourth embodiment may be configured to be included in the alarm systems 1 to 3 of the first to third embodiments. In this case, the external device 99 is provided so as to be connectable to the parent units 10, 30, and 50, and corresponds to the upper side in the tree structure of the alarm systems 1 to 3. In addition, the external device 99 is not limited to a mobile terminal or a personal computer, and may be a controller for a HEMS (Home Energy Management System) installed in the facility.
