Description

The present invention relates to an alarm device and an alarm system that configure a group that links an alarm with another alarm device to monitor an abnormality, and particularly relates to an alarm system that cooperates with an alarm between groups.

  Conventionally, residential alarm devices (hereinafter referred to as “residential alarms”) that detect and warn of abnormalities such as fires and gas leaks in homes have become widespread. There is also an increasing tendency to monitor the anomalies such as fires in each room by installing a vessel.

  In this way, when multiple dwelling units are installed in the dwelling unit, if there is a person in a room other than the room where the abnormality occurred, there is a risk that the alarm will not be heard and the response will be delayed or disasters such as fire may spread . For this reason, when the house alarm devices are connected to each other by wire and a fire is detected and alarmed by a certain house alarm device, an interlocking alarm that sends a signal to another house alarm device and simultaneously issues an alarm is made possible.

  However, there is a problem in that the cost of the connection between the resident alarms is high due to the necessity of wired work. This problem can be solved by using a wireless residence guard. In addition, with the recent reduction in power consumption of ICs for wireless circuits, even in an operation state in which signals can be received at all times in order to be able to receive signals from other home alarm devices, for example, more than 5 years can be put into practical use. The endurance of battery life is guaranteed, and the environment for practical use of wireless home alarms is getting ready.

  By the way, in the case of a wireless dwelling alarm, when a group is formed for a plurality of alarms installed in one dwelling unit, registration work for forming the group at the time of factory shipment or dwelling unit setting is performed. Registration using a radio signal is called, for example, notification registration.

  In this alarm registration, a plurality of alarm devices forming a group are placed on a work table, etc., one of the alarm devices is set as a registration transmission mode, the remaining alarm devices are set as a registration reception mode, and the registration transmission mode is set. The event signal including the transmission source code is transmitted from the alarm device, and this is received by the alarm device waiting for registration in the registration reception mode, and the group code is determined based on the transmission source code included in the received event signal. Create and register in memory.

In the monitoring state after the alarm registration is completed, when an alarm detects an abnormality such as a fire, an alarm is sent by itself and an event signal is transmitted to the other alarms. When an event signal is received, a transmission source code and a group code are acquired, a predetermined determination calculation is performed, and if the result of the determination calculation based on the registered transmission source code and group code registered in the memory matches, the same group It is determined that it is an event signal from a home alarm device belonging to, and an interlocking alarm is performed.

  By the way, in such an interlocking alarm system in which a group is constituted by a plurality of residence alarms, one group is constituted by a maximum of about 8 residence alarms. The reason for limiting the number of residential alarms constituting the group in this way is that when the maximum number is increased, there are problems such as an increase in memory capacity, an increase in communication load, and a complicated system operation.

  However, when installing more than the maximum number of housing alarms that make up a group, the two groups are constructed and operated separately, and the number of housing alarms that can be linked is the maximum number of groups. There are problems that are constrained by.

  On the other hand, a group of linked alarms may be configured by registering a specified number of slave units to one master unit. In such a case, multiple master units are provided, and the master units are linked and registered. It is also done. However, there is a problem that it is difficult to freely add a radio wave repeater or the like when the direct propagation of the radio wave is hindered due to the location where the parent devices are separated from each other.

Explanatory drawing which showed the collation pattern of the various transmission telegrams transmitted from the residence guard 10-22 of FIG.

  FIG. 1 is an explanatory diagram illustrating an outline of an alarm system according to the present invention, taking as an example a group configuration in which the maximum number of alarm devices that can be linked is four for ease of explanation.

  In FIG. 1, the group G1 is provided with four units of residence guards 10-11 to 10-14, while the group G2 is provided with four units of residence guards 10-21 to 10-24. The home alarm devices 10-1 to 10-24 are installed in places that require monitoring, such as a kitchen, a living room, a main bedroom, and a child room, which are provided in a house. For example, the home alarm devices 10-11 of the group G1 -10-14 are installed in each room on the first floor, while the house guards 10-21 to 10-24 of the group G2 are installed in each room on the second floor.

  For example, SN = 101, 102, 103, and 104 are stored in advance as the transmission source codes SN in the house alarm devices 10-11 to 10-14 of the group G1. In addition, GP1 = 205, 206, 207, 208 is assigned as group code GP1 indicating that it belongs to group G1 created in accordance with a group code creation rule that will be clarified later. Is stored in advance.

  On the other hand, SN = 201, 202, 203, 204 is stored in advance as the source code in the home police 10-21 to 10-24 of the group G2, and GP2 = 405 as the group code GP2 indicating that it belongs to the group G2. , 406, 407, and 408 are stored in advance.

  Here, since the residence guards 10-14 belonging to the group G1 and the residence guards 10-22 belonging to the group G2 are installed in a place having a communication distance capable of transmitting and receiving event signals, the group G1 and the group G2 In order to coordinate the alarm between the two, GP2 = 308 is stored in advance as a cooperation group code GP2 indicating that it also belongs to the group G2 in the home police 10-14, while the home police 10-22 in the group G2 In addition, GP1 = 306 is stored in advance as a cooperation group code GP1 indicating that it also belongs to the group G1.

  Two group codes GP1 and GP2 indicating that they belong to each of the groups G1 and G2 are stored in the resident police devices 10-14 and 10-22 that can communicate in order to link such groups G1 and G2. Therefore, when a fire is detected by any of the home alarm devices belonging to the group G1, in the home alarm device belonging to the group G2 through communication between the home alarm device 10-14 and the home alarm device 10-22 between the groups. A linked alarm can be issued.

  Similarly, when an abnormality such as a fire is detected in any of the residential alarms belonging to the group G2, in addition to the alarm in the group G2, an interlocking alarm can be performed in the residential alarm belonging to the group G1.

  FIG. 2 is an explanatory diagram showing an alarm operation by group cooperation when a fire is detected by the residential alarm 10-14 belonging to the group G1. In FIG. 2, when a fire is detected by the resident guard 10-14 of the group G1, the resident guard 10-14 issues an alarm as a link source by itself, and at the same time, the sender code SN, the group code GP1, and the linked group An event signal indicating a fire including the sign GP2 is generated and wirelessly transmitted.

  The event signal from the home alarm device 10-14 is received by the home alarm devices 10-11, 10-12 and 10-13 belonging to the group G1, and stored and registered in the group code GP1 included in the received event signal. The group code GP1 is collated to determine that the event signal is from a resident alarm device belonging to the same group, and an alarm as an interlocking destination is issued.

  The event signal from the home alarm device 10-14 is also received by the home alarm device 10-22 of the group G2. The home alarm device 10-22 determines from the cooperation group code GP2 included in the received event signal that it is an event signal from a home alarm device belonging to the group G1 that is in a cooperative relationship, and the home alarm device 10-22 serves as a link destination. An alarm is issued, and an event signal in which the group code GP1 indicating the group G1 in the received event signal is changed to the group code GP2 indicating the group G2 is relayed and transmitted.

  The event signal relayed out from the home alarm device 10-22 is received by the home alarm devices 10-21, 10-23, and 10-24 of the group G2, and is the same from the changed group code GP2 included in the event signal. It is determined that the event signal belongs to the group, and the resident alarm devices 10-21, 10-23, and 10-24 perform an interlocking destination alarm based on the relayed event signal.

  FIG. 3 is an explanatory diagram showing an alarm operation by group cooperation when a fire is detected by the group G2 home alarm. In FIG. 3, when a fire is detected by the residential police 10-21 belonging to the group G2, the residential police 10-21 performs an alarm as a linkage source and transmits an event signal including the transmission source code SN and the group code GP2. To do. The event signal from the home guard 10-21 is received by the other home guards 10-22, 10-23, and 10-24 belonging to the group G2, and the group code GP2 included in the event signal is decoded to be the same. It is determined that it belongs to a group, and an alarm is issued as a link destination.

  Furthermore, in the resident alarm 10-22 that cooperates with the group G1, an alarm signal including a transmission source code SN, a group code GP2, and a cooperation group code GP1 is output at the same time as an alarm as an interlocking destination is output. Is generated and relayed.

  The event signal relayed from the mortgage alarm device 10-14 is received by the mortgage alarm device 10-11 to 10-13, and it is determined from the changed group code GP1 that the event signal belongs to the same group. Is done.

  At this time, the resident alarm 10-14 receives this event signal, compares the group code GP1 included in this signal with the group code stored and registered in the signal, and the signal from the resident alarm belonging to the own group. At the same time, an alarm as a linkage destination is output, and at the same time, the group code GP2 of the received event signal is changed to GP1 which is its own group code, and relay transmission is performed.

  The event signal relayed from the mortgage alarm device 10-14 is received by the mortgage alarm device 10-11 to 10-13, and it is determined from the changed group code GP1 that the event signal belongs to the same group. Is done.

  Here, when the mortgage guard 10-22 receives the event signal from the ward guard 10-21 and relays the event signal to the ward guard 10-14, the group code GP2 and the cooperation group code GP1 Instead of generating and transmitting an event signal including, a fire event signal in which the cooperation group code GP1 stored and registered as a group code is set may be transmitted.

  FIG. 4 is a block diagram showing an embodiment of a residence guard according to the present invention, showing details of the residence guard 10-14 that belongs to the group G1 in FIG. The group G2 residence guard 10-22 and the group G1 residence guards 10-11 to 10-13 having a direct interlocking relationship with the group G1 to be linked to the group G1 It shows.

  The home alarm device 10-14 includes a processor 12, and the processor 12 is provided with a wireless circuit unit 14 including an antenna 15, a memory 16, a sensor unit 18, a notification unit 20, an operation unit 22, and a battery power source 24. Yes. The structure of such a residence guard 10-14 is the same also about the other residence guards 10-11 to 10-13, 10-22.

  The wireless circuit unit 14 is provided with a transmission circuit 26 and a reception circuit 28 so that event signals can be wirelessly transmitted / received to / from other house alarm devices. The radio circuit unit 14 has a configuration conforming to the standard of a specific low power radio station in the 400 MHz band, for example, in Japan. Of course, the radio circuit unit 14 has contents conforming to the standard of the assigned radio station in the area in places other than Japan.

  The receiving circuit 28 performs intermittent reception. The intermittent reception operation of the reception circuit 28 is, for example, intermittent reception of a period T12 (= T1 + T2) in which a pause time of T2 = 10 seconds is placed, for example, following a reception operation time of T1 = 5 milliseconds. Corresponding to this intermittent reception, the transmission circuit 26 continuously transmits the event signal for T3 time which becomes the intermittent reception cycle T12 or more.

  The memory 16 is provided with a transmission source management table 30-14 for managing a transmission source code serving as an ID (identifier) for identifying the residential alarm, and the transmission source code management table 30-14 includes the residential alarm 10-. In addition to the 14 transmission source codes, the transmission source codes of the other mortgages 10-11 to 10-13 belonging to the same group G1 obtained by the registration operation initially performed for the group configuration are registered. .

  FIG. 5 (A) shows the contents of the transmission source management table 30-14 provided in the memory 16 of the residence police device 10-14. The transmission source management table 30-14 contains the residence police devices 10-11 to 11-11 belonging to the group G1. SN = 101, 102, 103, 104 is stored as the source code SN of 10-14.

  For example, when a factory code is installed or installed in a house, the transmission source codes are registered in the transmission source management table 30-14 in such a manner that four dwelling devices 10-11 to 10-14 are arranged in one place such as a work table. This can be realized by performing the information registration work.

  In the alarm registration work, any one of the residence police devices 10-11 to 10-14 is sequentially sent as a registration transmission mode to transmit a registration event signal, and another residence which is in a standby state in the registration reception mode. The alarm device receives the registration event signal, acquires the transmission source code included in the registration event signal, and registers the transmission source code in the transmission source management table 30-14 of the memory 16.

  FIG. 5 (B) shows the registered contents of the transmission source management table 30-22 stored in the memory of the home alarm device 10-22 included in the cooperation destination group, and the home alarm device 10- belonging to the group G2 SN = 201, 202, 203, and 204 are stored as source codes SN through the notification registration work in 21 to 10-24.

  Here, three decimal digits are shown as the transmission source code SN registered in the transmission source management tables 30-14 and 30-22 in FIG. 5 for the sake of simplicity, but as the transmission source code SN actually used. Uses, for example, a 26-bit code because it is necessary to assign a code unique to, for example, millions of residential alarms used in the alarm system of the present invention.

  Referring to FIG. 4 again, the memory 16 stores a group code 36 and a cooperation group code 38 in advance. The group code 36 is a code indicating that the residence guard 10-14 belongs to the group G1. In this embodiment, the group code 36 is stored in the transmission source management table 30-14 acquired through the notification registration work in the memory 16. The group code GP1 is automatically determined according to the algorithm shown in the following example on the basis of the stored transmission source codes of the home guards belonging to the group G1.

Now, as shown in the transmission source management table 30-14 shown in FIG. 5A, it is assumed that the transmission source codes SN = 101, 102, 103, and 104 of the four mortgages belonging to the group G1 are obtained. For such a transmission source code SN, a reference value R unique to the group is first determined. For example, the reference value R = MAX (101, 102, 103, 104) = 104.
As a reference value R, the largest of the transmission sources belonging to the same group is defined as

  The reference value may be a minimum value other than the maximum value, or an arbitrary transmission source code.

Next, the own group code GP1 is determined for each residential alarm. The group code GP1 is determined according to the following equation.
(Group code GP1) = (own transmission source code SN) + (reference value R) (1)
For example, based on the transmission source code SN of the transmission source management table 30-14 in FIG.
House alarm 10-11: GP1 = 101 + 104 = 205
Housekeeper 10-12: GP1 = 102 + 104 = 206
House alarm 10-13: GP1 = 103 + 104 = 207
Housekeeper 10-14: GP1 = 104 + 104 = 208
When the transmission source codes SN and the group codes GP1 in the residential police devices 10-11 to 10-14 belonging to the group G1 are collected, the group G1 management table of FIG. 6 is obtained.

  Similarly, with respect to the residential alarm devices 10-21 to 10-24 belonging to the group G2 in FIG. 1 shown in FIG. The group code GP2 corresponding to the transmission source code SN as shown in the group G2 management table shown in FIG. 7 is determined based on the equation (1) determined as the reference value R.

That is, the group codes of the residential alarms 10-21 to 10-24 are obtained as follows.
House alarm 10-21: GP1 = 201 + 204 = 405
House alarm 10-22: GP1 = 202 + 204 = 406
Housekeeper 10-23: GP1 = 203 + 204 = 407
Housekeeper 10-24: GP1 = 204 + 204 = 408
Furthermore, in the group G1 residence guard 10-14 that cooperates with the group G2 residence guard 10-22 shown in FIG. Cooperation group code | symbol 38 is a group code | cord | chord which shows that the resident guard 10-14 takes cooperation with the group G2.

The cooperation group code GP2 is obtained from the equation (1) using the transmission source code SN = 104 of the resident guard 10-14 and the reference value R = 204 used for the calculation of the group code GP2 of the group G2. It is done. That is, the cooperation group code GP2 of the mortgage alarm 10-14 is GP2 = 104 + 204 = 308.
As required. This is the value 308 shown in the cooperation group code GP2 of the group G1 management table of FIG.

Similarly, the cooperative group code GP1 indicating that it belongs to the group GP1 is also calculated for the residential policer 10-22 of the group G2 that cooperates with the residential policer 10-14 of the group G1. That is, in the resident alarm device 10-22, based on its own transmission source code SN = 202 and the reference value R = 104 of the group G1, GP1 = 202 + 104 = 306 as the cooperation group code GP1 from the above equation (1).
This is a value 306 shown in the cooperation group code GP1 of the group G2 management table of FIG.

  In the present embodiment, the event signal 32 having the format shown in FIG. 8 is transmitted when the event signal that detects the fire is transmitted. The event signal 32 includes a transmission source code 34, a group code 36, a cooperation group code 38, and an event code 40.

  As described above, the transmission source code 34 is a 26-bit code, for example. The group code 36 and the cooperation group code 38 are, for example, 28-bit codes. The event code 40 is, for example, a 3-bit code. “001” is a fire, “010” is a gas leak, “011” is a failure, “100” is restored, and the rest is reserved. Of course, when the event contents increase, the number of bits can be increased to 4 bits and 5 bits as necessary.

  The group determination when the event signal 32 is received will be clarified in detail when the first interlocking alarm unit 56 and the second interlocking alarm unit 58 provided in the processor 12 are described.

  Referring again to FIG. 4, the sensor unit 18 of the home alarm device 10-14 is provided with a smoke detection unit 42 in this embodiment, and outputs a smoke detection signal corresponding to the smoke density to the processor 12. Yes. In addition to the smoke detector 42, the sensor unit 18 may be provided with a thermistor for detecting the temperature due to a fire, or other detection element for detecting a fire phenomenon. Further, in the case of a residence warning device for gas leak detection, a gas leak sensor is provided in the sensor unit 18.

  The notification unit 20 is provided with a speaker 44 and an LED 46. The speaker 44 outputs a voice message and an alarm sound from a voice synthesis circuit (not shown). The LED 46 displays an abnormality or failure such as a fire by blinking, blinking, or lighting.

  The operation unit 22 is provided with an alarm stop switch 48 and a registration switch 50. The alarm sound can be stopped by operating the alarm stop switch 48. The alarm stop switch 48 also serves as an inspection switch in this embodiment.

  That is, the alarm stop switch 48 is effective when an alarm sound is output from the notification unit 20 through the speaker 44. On the other hand, the alarm stop switch 48 functions as an inspection switch in a normal monitoring state that does not require an alarm sound. When the inspection switch is pressed, a predetermined internal function inspection is performed, and a voice message indicating the result is output from the notification unit 20. Is done.

  The registration switch 50 performs a registration process for forming a linkage and a cooperation group. In other words, when installing the factory guards or homes, for example, when the residence switches 10-11 to 10-14 constituting the group G1 are arranged in one place such as a work table and the registration switch 50 is operated, the registration event signal is sent to another residence. The registration event signal is received by another residence alarm device that is transmitted to the alarm device and is in a standby state in the registration reception mode, and the transmission source code is registered in the transmission source management table 30-14 shown in FIG. Then, by the function of the group code registration processing unit 52, which will be clarified in the following description, the determination by the calculation of the group code GP1 shown in the group G1 management table of FIG. 6 and the determination of the cooperation group code GP2 are performed.

  The battery power source 42 uses, for example, a predetermined number of alkaline dry batteries, and the battery capacity compensates for the battery life of about 10 years by reducing the power consumption of the entire circuit unit including the radio circuit unit 14 in the residential alarm. .

  The processor 12 includes hardware such as a CPU, a ROM, a RAM, an AD conversion port, and various input / output ports. As functions realized by execution of a program by the CPU, a group code registration unit 52, an abnormality monitoring unit 54, An interlocking alarm part 57 including a first interlocking alarm part 56 and a second interlocking alarm part 58 is provided.

  The group code registration unit 52 operates the registration switch 50 in a state in which a plurality of residential alarms constituting a group are arranged in one place such as a work table at the time of factory shipment or installation in a house, thereby The registration process of the group code and the cooperative group code in the memory 16 is executed. The contents of this registration processing are the contents shown in the registration of the transmission source management table 30-14 in FIG. 5 and the determination of the group code GP1 and the cooperation group code GP2 in the group G1 management table shown in FIG.

  When the smoke detection signal from the smoke detection unit 42 provided in the sensor unit 18 exceeds the fire level and detects a fire, the abnormality monitoring unit 54 outputs an alarm sound indicating the interlock source from the speaker 44 of the notification unit 20, for example, “Woo, "Fire alarm has been activated. Please check" repeatedly, and at the source code 34, group code 36, linkage group code 38, and event signal 40 indicating fire as shown in the format of FIG. An event signal in which a certain “001” is set is transmitted from the antenna 15 to another house alarm device by the transmission circuit 26 of the wireless circuit unit 14.

  When the first interlocking alarm unit 56 receives an event signal indicating a fire alarm from another house alarm by the receiving circuit 28 of the wireless circuit unit 14, the first interlocking alarm unit 56 decodes the event signal and acquires a transmission source code and a group code. Based on the acquired transmission source code and group code, it is determined whether or not they belong to the same group.

Here, the transmission source code acquired from the received event signal is SNx, the group code is GP1x, the own transmission source code stored in the memory 16 of the resident guard 10-14 is SNy, and the group code is GP1y. Then, it is determined whether or not they belong to the same group by the following determination algorithm.
(Group code GPx) − (source code SNx)
= (Group code GPy)-(Source code SNy)
(2)
Equation (2) is obtained by obtaining the reference value R from the SNx and the group code GP1x of the transmission source code acquired from the received event signal, and storing the transmission source code stored in the memory 16 of the resident guard 10-14. Is obtained from SNy and group code GP1y, and it is determined whether or not they belong to the same group based on whether or not the reference value R matches.

For example, if the residence signal 10-14 received an event signal from the residence guard 10-11 of the group G1, the transmission source code SNx and the group code GP1x obtained from the received event signal are SNx = 101.
GP1x = 205
Because
(GP1x)-(SNx) = 205-101 = 104
Is calculated.

Subsequently, based on SNy = 104 and group code GP1y = 208, its own transmission source code acquired from the memory 16 of the resident guard 10-14,
(GP1y)-(SNy) = 208-104 = 104
Is calculated. This may be calculated in advance and stored in the storage unit.

  Since the reference value R obtained from the received event signal and the reference value R obtained from the value in the memory 16 are both equal to R = 104, the first interlocking alarm unit 56 receives the same event signal. Based on the event code included in the event signal, the fire alarm as the linkage destination is determined from the speaker 44 of the notification unit 20, for example, “Woo, another fire alarm is detected. “Check that it has been activated.” Repeatedly.

  On the other hand, if the reference value R calculated from the event signal and the reference value R calculated from the value in the memory 16 do not coincide with each other, it is determined that the event signal is not from the mortgage of the same group, and the event signal is discarded. Instead of simply discarding the event signal, a message such as “A signal outside the group has been received” may be output.

  Further, when the alarm sound of the interlocking source is output from the speaker 44 of the notification unit 20, the LED 46 is blinked. On the other hand, when the alarm sound of the interlocking destination is output, the LED 46 is blinked, and thereby the interlocking source alarm and the interlocking destination alarm can be distinguished. I am doing so.

Note that the determination of whether or not they belong to the same group is made by modifying the above equation (2) (group code GPy) =
(Group code GPx)-(source code SNx) + (source code SNy) (3)
A determination calculation may be performed.

When the second interlocking alarm unit 58 determines that the first interlocking alarm part 56 does not belong to the same group, the source code included in the event signal from the other alarming device is based on the equation (2). SNx and cooperation group codes GP2x to (GP2x)-(SNx)
The reference value R is calculated as follows, and this is the difference (GP2y) − (SNy) between the own cooperation group code GP2y obtained from the memory 16 and the transmission source code SNy.
When it matches with the reference value by, it judges that it belongs to the same cooperation group, and performs an alarm as an interlocking destination based on the event content.

For example, if the resident guard 10-14 receives an event signal from the resident guard 10-22 of the group G2, the transmission source code SNx = 202 and the cooperation group code GP1x = 306 obtained from the event signal (GP1x) − (SNx) = 306−202 = 104
This is obtained from its own transmission source code SNy = 104 obtained from the memory 16 and the group code GP1y (GP1y) − (SNy) = 208−104 = 104
When it matches the reference value R, it is determined that they belong to the same linkage group, and an alarm as a linkage destination is issued.

  Further, the second interlocking alarm unit 58 discriminates that the event signal is from a resident alarm device belonging to the same cooperation group and performs an alarm as an interlocking destination, and then sets the group code GP2 in the received event signal to its own. It changes to group code | cord | chord GP1, and relay-transmits to the other residence police devices 10-11 to 10-13 which belong to group G1.

  As a result, the household alarm device 10-14 that received the alarm signal from the household alarm device 10-22 of the group G2 and warned the other household alarm devices 10-11 to 10-13 belonging to the group G1 to the group G2. An event signal from the group 10-22 can be relayed to issue an alarm as a linkage destination.

  It should be noted that the transmission source code must be added to the event signal according to regulations of the Radio Law regardless of whether it is necessary for realizing the functions of the present invention.

  For the group code and the cooperation group code, for example, an arbitrary value for each group determined separately may be registered by another method at the time of shipment or installation. The group determination when the event signal is received may not be based on the calculation as described above, but simply based on whether or not the code in the event signal matches the code stored in the storage unit. good. Furthermore, without using a group code or a linkage group code, linkage within the same group and / or linkage between different groups may be performed by transmission / reception of source codes, storage registration, and identification verification.

  FIG. 9 is a flowchart showing an outline of the fire monitoring process in the residential alarm of FIG. In FIG. 9, the processor 12 provided in the home alarm device 10-14 performs initialization processing in step S <b> 1 when the power is turned on, and then proceeds to step S <b> 2, and smoke from the smoke detector 42 provided in the sensor unit 18. The presence or absence of a fire alarm is determined based on whether the detection signal exceeds the fire level.

  When the fire report is determined in step S2 (fire occurrence is determined), the process proceeds to step S3 to transmit a fire report event signal. As shown in FIG. 8, in addition to the transmission source code 34, the group code 36, and the cooperation group code 38, this event signal creates an event signal 32 with the event code 40 set to fire “001”, and wirelessly transmits from the radio circuit unit 14. Send.

  Subsequently, in step S4, a fire alarm as an interlocking source is performed by sound output from the speaker 44 of the notification unit 20, and at the same time, a blinking display indicating the interlocking source is performed by the LED 46. Subsequently, in step S5, it is determined whether or not a stop operation has been performed by the alarm stop switch 48. When the stop operation is determined, the process proceeds to step S6 to stop the alarm.

  On the other hand, if the fire alarm is not determined in step S2, whether or not an event signal has been received is determined in step S7. When the event signal is received in step S7, the process proceeds to step S8, and the transmission source code and the group code included in the received event signal are acquired.

  Subsequently, in step S9, the transmission source code and the group code stored in the memory 16 are read out. Subsequently, in step S10, based on the equation (2), a reference value obtained by subtracting the transmission source code from the group code acquired from the event signal and a transmission source code are subtracted from the own group code read from the memory 16 in step S9. In step S11, it is checked whether or not the same reference value has been calculated. If the same reference value is calculated, it is an event signal from another residential alarm device belonging to the same group, so the process proceeds to step S17, and a fire alarm is performed as the interlocking destination.

  On the other hand, if the reference values are different in step S11, the process proceeds to step S12, where the transmission source code and the cooperation group code are acquired from the event signal, and then in step S13, the transmission source code and the own transmission source code are linked. Read the group code.

  Subsequently, in step S14, a determination calculation process for obtaining a reference value obtained by subtracting the transmission source code from the cooperation group code acquired from the event signal and a reference value obtained by subtracting the transmission source code from the own cooperation group code acquired from the memory 16. Execute.

  Subsequently, in step S15, it is determined whether the obtained two reference values are the same value. If they are the same, in step S16, an event signal is generated by changing the group code of the received event signal to its own group code. Is relayed to cause other dwelling devices in the same group to issue an alarm. Subsequently, in step S17, a fire alarm is performed as a linkage destination.

  In addition, although the fire monitoring process of FIG. 9 took the process of the residence guard 10-14 of the group G1 as an example, it is the same also about the residence guard 10-22 of the group G2 which cooperates with the group G1. .

  On the other hand, with regard to the housing police devices 10-11 to 10-13 of the group G1 and the housing police devices 10-21, 10-23, and 10-24 of the group G2 that are not linked with other groups, FIG. Steps S1 to S10 are the same as those of the residential alarm devices 10-14 and 10-22. However, if the reference value calculated from the event signal in step S11 and the reference value calculated from the value of the memory 16 do not match, step S12 The process proceeds to S16, but since the own cooperation group code is not stored in the memory 16, the reference value calculated in Step S10 is always inconsistent, relaying the event signal in Step S15, and the fire of the interlock destination There will be no alarm. Of course, steps S12 to S16 may be skipped.

  FIG. 9 shows an example of processing in the case of a fire alarm. When an alarm stop operation is determined in step S5 and an alarm stop is performed in step S6, an event signal indicating the alarm stop is sent to another address. You may make it transmit to an alarm and stop interlocking. About the interlock stop of this alarm, in addition to the interlock stop in the group, by sending an event signal including the cooperation group code from the residence guard 10-14 to the residence guard 10-22 of the group G2, on the group G2 side Alternatively, the alarm interlocking may be stopped.

  Such cooperation between the groups G1 and G2 is an event signal indicating failure detection even when a failure is detected due to an automatic test of the sensor unit 18 or when a failure is detected such as low battery detection due to a voltage drop of the battery power supply 24. The alarm may be linked not only within the group but also to other groups having a cooperative relationship.

  FIG. 10 is an explanatory diagram showing an outline of an alarm system according to the present invention in the case where one residence guard is added to the group G1 having a maximum number of four. In FIG. 10, the monitoring system was first constructed by installing the four residence guards 10-11 to 10-14 constituting the group G1 in the house, but after that, another residence guard is required. In this case, since it cannot be included in the group G1, the newly added residence guard 10-21 is added as a residence guard constituting another group G2.

The resident alarm 10-21 of the group G2 to be added has the transmission source code SN = 201, and there is only one transmission source code SN since there is only one resident alarm device constituting the group G2. Therefore, this is the reference value R. Therefore, the group code GP2 of the group G2 is GP2 = 201 + 201 = 402 from the above equation (1).
As determined.

Further, in order to cooperate with the group G1, based on the reference value R = 104 of the group G1, as a cooperation group code GP1, GP1 = 201 + 104 = 305
To set.

  Thus, about the newly installed resident guard 10-21, the resident police exceeding the group G1 which is a maximum of four by registering the group code GP2 and the cooperation group code GP1 based on the transmission source code SN as the group G2. Can be easily added.

  FIG. 11 is an explanatory diagram showing an outline of an alarm system according to the present invention, taking as an example a group configuration in which the maximum number is eight. In FIG. 11, the group G1 is composed of eight housing police devices 10-11 to 10-18, and the group G2 is composed of eight housing police devices 10-21 to 10-28.

SN = 101, 102,... 108 as the transmission source code SN for the housing police devices 10-11 to 10-18 of the group G1.
As the group code GP1, based on the maximum transmission source code SN = 108, GP1 = 209, 210, 211,... 216
Is registered.

Similarly, the transmission source codes SN of the household police devices 10-21 to 10-28 of the group G2 are SN = 201, 202, 203,... 208.
Since the group code GP2 has the reference value R = 208, GP2 = 409, 410, 411,... 416 from the equation (1).
Is registered.

Furthermore, since the housing guard 10-16 of the group G1 and the housing guard 10-22 of the group G2 are installed at a communicable position, the source code is set as the cooperation group code G2 in the housing guard 10-16. Cooperation group code GP2 = 106 + 208 = 314 obtained by adding the reference value R = 208 of group G2 to SN = 106
Is registered.

Moreover, the cooperation group which added the reference value R = 108 of the group G1 of a cooperation destination to the self transmission source code SN = 202 as cooperation group code | cord GP1 for taking cooperation with the group G1 to the home guard 10-22 of the group G2 Reference sign GP1 = 202 + 108 = 310
Is registered.

  FIG. 12 is a group G1 management table showing the registration contents of the transmission source code SN, the group code GP1, and the cooperation group code GP2 of the residence guard 10-16 in the group G1 of FIG. Indicates.

  FIG. 13 shows a group G2 management table in which the transmission source code SN, the group code GP2, and the cooperation group code GP1 of the residence guard 10-22 are registered in the group G2 of FIG. ing.

  In this way, two group codes that enable communication with the group that cooperates with the own group are registered in the residence guards 10-16 and 10-22 arranged at positions where communication is possible between the groups G1 and G2. By doing so, it is possible to link alarms between groups, and it becomes possible to interlock the addition of residential alarms not restricted by the maximum number (upper limit number) of residential alarms that can form a group.

  Here, in FIG. 2 and FIG. 3, the communication path is shown in a simplified manner for the sake of simplicity. For example, the resident guard 10-11 in the same group G1 receives the event signal from the resident guard 10-14. There is also a case where relay transmission is performed to the home alarm device 10-12 or 10-13.

  Also, in FIG. 3, the home alarm device 10-21 as the alarm source transmits an event signal including the group code GP2, and the home alarm device 10-22 that receives the event signal stores and registers the event signal in its own storage unit. Matching with the group code GP2, confirming and accepting the match, further transmitting an event signal including the group code GP2 and the cooperation group code GP1, and receiving the event signal by the resident alarm device 10-14, to which it belongs The example which transmits as an event signal containing group code | cord GP1 to the other residence police (10-11 to 10-13) of a group is given.

  However, in the present invention, in order to coordinate between groups, what kind of event signal is transmitted when an abnormality is detected, and how is collation performed when an event signal is received Whether to relay such an event signal is not limited to this example, and various deformation patterns are conceivable.

That is, the basic rule for establishing cooperation between two different groups in the present invention is as follows.
(1) The cooperation group code is simply a second group code.
(2) Therefore, it is not necessary to distinguish the position in the message by the group code and the cooperation group code.
(3) The storage position of the group code and the cooperative group code in the storage unit may not be distinguished.
(4) Each of the group code and the cooperation group code may be a predetermined fixed value (the same value within the group).
(5) It can be validated if any one of the two group codes in the message matches with two (or one) group codes in the storage unit.

  The deformation patterns including the examples of FIGS. 2 and 3 based on the rules (1) to (5) are collectively shown in FIGS. 14 to 16.

  FIG. 14 shows the codes stored in the storage units of the group G1 residence guards 10-1 to 10-14 and the group G2 residence guards 10-21 to 10-24 shown in the examples of FIGS. This is a list 50 showing patterns, and a case where fixed values are used as symbols A and B according to the rule (4) is taken as an example.

  The stored value is a value actually stored in the storage unit, and G1 and G2 indicating group names are used for easy understanding of the explanation. The codes A and B stored in the storage unit also correspond to the rules (1) and (3).

  15 shows a list 60 of transmission message patterns when an abnormality is detected by the alarm source residence guard 10-21 of FIG. 3 and the alarm source residence guard 10-14 of FIG. 21 shows a collation pattern and a list 70 of transmitted message patterns of the residence guard 10-22 that has received the transmitted message patterns from -21 and 10-14.

In the list 60, when the home police 10-21 in the example of FIG. 3 detects an abnormality, the transmission message pattern P1 is “transmission source code + group code (G2) + event code”.
Send a message that becomes Here, for the group code, the stored values shown in the list 50 of FIG. 14 are put in parentheses.

This telegram is received by the residential alarm 10-22 in the list 70, and as a matching pattern,
(1) The group code of the received message matches the stored code A (group code = A)
(2) The group code of the received message matches the stored code A (group code = AorB)
If any of the above is satisfied, the received message is accepted as valid.

  The resident guard 10-22 that has received the received message transmits the message of the transmitted message pattern P1 or P12 shown on the right side thereof.

The transmission message pattern P11 is:
"Sender code + group code (G2) + cooperation group code (G1) + event code"
The “cooperation group code (G1)” is added to the received message pattern P1, thereby enabling the reception of messages by the mortgage of another group G1. In addition, since “group code (G2)” is also included, it is possible to accept a telegram at the same group G2.

The transmitted message pattern P12 is:
"Sender code + group code (G2) + event code"
The “group code (G1)” is changed to “group code (G2)” with respect to the received telegram pattern P1, and the telegram can be received by the home guards of the same group G2.

Also, “[and transmission source code + group code (G1) + event code]” shown in the second half of the transmission message pattern P12.
Is a message to be sent as needed. For example, when you want to send it to other group G1 housing alarms to which the alarm source belongs, or when you want to send it as a response to the cooperation source alarm device, After sending the message, send the latter half of the message.

  FIG. 16 shows a list 80 of collation patterns of the home guards that have received the transmission message pattern from the list 70 of FIG.

  For example, if the resident alarm 10-22 in the list 70 in FIG. 15 transmits the message transmission pattern P11 or P12, the resident alarm devices 10-11 to 10-13 in the list 80 in FIG. 16 change to the message transmission pattern P11 or P12. A received telegram is accepted on condition that the included group code matches group code A in the storage unit (group code = A).

  Next, looking at the case where the mortgage guard 10-14 of the group G1 in the list 60 of FIG. 15 corresponding to the example of FIG. 2 detects an abnormality, in this case, the transmission telegram pattern P2 or P3 is transmitted.

The transmitted message pattern P2 is:
"Sender code + group code (G1) + cooperation group code (G2) + event code"
It is.

The transmission message pattern P3 is:
“Sender code + Group code (G1) + Event code and
"Sender code + cooperation group code (G2) + event code"
The two messages are transmitted in order.

  The first transmission message is a transmission to the home alarm device of the same group G1. The second transmission message is a transmission to the other group G2.

The transmission message pattern P2 from the home alarm device 10-14 in the list 60 is received by the home alarm device 10-22 in the list 70 as shown by a dashed arrow, and any one of the following five conditions is set as a matching pattern. If it satisfies, the received message is accepted.
(1) The group code of the received message matches the stored code A (group code = A)
(2) The group code of the received message matches the stored code A (group code = AorB)
(3) Cooperation group code of received message matches storage code A (group code = A)
(4) Cooperation group code of received message matches storage code A (group code = AorB)
(5) The group code of the received message matches the storage code A, and the cooperation group code matches the storage code B (group code = Aand cooperation group code = B).
The house alarm device 10-22 that has received the received message transmits any one of the transmitted message patterns P21, P22, and P23 shown in the pattern on the right side thereof.

The transmitted message pattern P21 is:
"Sender code + group code (G2) + cooperation group code (G1) + event code"
The group code value is changed from (G1) to (G2) for the received message pattern P2, and the linkage group code value is changed from (G2) to (G1). As a result, it is possible to accept a telegram at the same group G2 residence guard. Further, since the group code value (G1) is also included, it is possible to accept a telegram at the home guard of another group G1.

The transmitted message pattern P22 is:
"Sender code + group code (G2) + event code"
The “group code (G1)” is changed to “group code (G2)” with respect to the received telegram pattern P1, and the telegram can be received by the home guards of the same group G2.

The transmission message pattern P23 is:
"Sender code + group code (G2) + event code"
If necessary, the latter half “[and transmission source code + group code (G1) + event code]”
Send. The first telegram of the first half is the same as P22, but the latter half of the telegram is sent to the alarm device of the other group G1 that is the alarm source, or when the response is received by the alarm device of the cooperation source If you want to send as.

  The telegram transmission patterns PP21, 22 or P23 from the residential alarm device 10-22 in the list 70 in FIG. 15 are received by the residential alarm devices 10-21, 10-23, 10-24 in the list 80 in FIG. A received telegram is accepted on condition that the included group code matches group code A in the storage unit (group code = A).

  Further, the transmission message pattern P3 from the resident alarm device 10-14 in the list 60 is received by the resident alarm device 10-22 in the list 70 as shown by the broken arrow, and the same five conditions as the transmission message pattern P2 are satisfied. If either one is satisfied, the received message is accepted.

  The home guard 10-22 that has received the received telegram transmits a telegram of any one of the transmit telegram patterns indicated by the patterns P31, P32, and P33 on the right side thereof. Transmission message patterns P31, P32, and P33 are the same as transmission message patterns P21, P22, and P23.

  The message transmission patterns P31, 32, or P33 from the residential alarm device 10-22 in the list 70 in FIG. 15 are received by the residential alarm devices 10-21, 10-23, and 10-24 in the list 80 in FIG. A received telegram is accepted on condition that the included group code matches group code A in the storage unit (group code = A).

  In addition, although the above embodiment is an example of a residential alarm device for fire detection, other appropriate abnormalities such as a gas leak alarm device and a security alarm device are detected. The mutual cooperation of the group of this embodiment is applicable per alarm device.
