The first environment sensor 3A, the second environment sensor 3B, the gas stove 5, the fire alarm 6, the first infrared remote controller 7A, and the second infrared remote controller 7B each use a second communication method compatible with the LAN 11. It has a function to communicate with

An application program (application) 41 for using the alarm system 1 is downloaded to the communication terminal device 8 such as the SP 8A and the tablet 8B that can be connected to the WAN 13 .

The server 10 acts as an intermediary between the device D, the alarm device 2 and the communication terminal device 8 and controls the operation of the alarm system 1 . The server 10 includes an arithmetic processing unit 30 , an equipment management database (equipment management DB) 31 , and a history database (history DB) 32 .

The arithmetic processing unit 30 performs arithmetic processing on data. For example, the arithmetic processing unit 30 has a function of creating notification information to be notified to the communication terminal device 8 based on data received from the alarm device 2 . Further, for example, the arithmetic processing unit 30 has a function of creating a screen to be displayed on the communication terminal device 8 using data received from the alarm device 2 . Further, for example, the arithmetic processing unit 30 has a function of calculating the risk of heat stroke based on the data received from the alarm device 2 .

The history DB 32 accumulates and stores usage histories of the device D, the alarm device 2 and the communication terminal device 8 . The information stored in the history DB 32 includes, for example, the history of abnormality detected by the alarm device 2, the history of sensor information detected by the sensor, the history of the operating state of the device D, and the and the history of notifying the communication terminal device 8 by the server 10, and the like.

The device management DB 31 stores the device D and the communication terminal device 8 in association with each other via the alarm device 2 .

FIG. 4 is a diagram for explaining the configuration of the device management DB 31. As shown in FIG. The equipment management DB 31 includes, for example, a communication terminal identification information storage area 311 , an alarm device identification information storage area 312 , and a device identification information storage area 313 .

Alarm device identification information for specifying the alarm device 2 is stored in the alarm device identification information storage area 312 . The alarm device identification information is, for example, a mobile phone phone number, MAC address, or manufacturing number. For example, the alarm device identification information is registered in the device management DB 31 of the server 10 when the alarm device 2 is shipped.

The device identification information storage area 313 stores device identification information that identifies the device D installed in the house. Device identification information included in the alarm device information table 221 received by the server 10 from the alarm device 2 is stored in the device identification information storage area 313 .

For example, the gas alarm device 2A accesses the server identification information (IP address) stored in the first storage area 222 of the alarm device information table 221 after building the LAN 11 using the LAN building unit 28, and accesses the server identification information (IP address) via the WAN 13. to connect to the server 10. The gas alarm device 2A transmits the alarm device information table 221 to the server 10 using the first communication IF23. The server 10 stores a record in which the alarm device identification information "090-XXX-XX01" stored in the second storage area 223 of the received alarm device information table 221 is stored in the alarm device identification information storage area 312. Extract from management DB31. Then, the server 10 stores the device identification information of the extracted record, such as the device identification information of the first environment sensor 3A and the second environment sensor 3B, stored in the third storage area 224 of the received alarm device information table 221. Store in area 313 . As a result, in the device management DB 31, the first environment sensor 3A, the second environment sensor 3B, the gas stove 5, the first infrared remote controller 7A, the second infrared remote controller 7B, and the fire alarm 6 are connected to the gas alarm 2A. associated with. The server 10 may periodically receive the alarm information table 221 from the gas alarm 2A after initial setting of the gas alarm 2A, and rewrite the device D associated with the gas alarm 2A.

Communication terminal identification information for specifying the communication terminal device 8 is stored in the communication terminal identification information storage area 311 . Communication terminal identification information is, for example, a telephone number, an IP address, a manufacturing number, and the like. For example, the user who installed the gas alarm 2A in the house 12 transmits the user registration information to the server 10 when the application 41 downloaded to the SP 8A is launched for the first time. The user registration information includes, for example, name, address, e-mail address, customer reference number, telephone number of SP8A, and alarm identification information of gas alarm 2A. When the server 10 receives the user registration information from SP8A, the server 10 stores a record in which the alarm device identification information "090-XXX-XX01" included in the user registration information is stored in the alarm device identification information storage area 312. Extract from DB31. Then, the server 10 stores the telephone number "AAA" of SP8A included in the user information in the communication terminal identification information storage area 311 of the extracted record. Thereby, SP8A is associated with gas alarm device 2A in device management DB31.

Returning to FIG. 1 , the management device 9 is a PC that is directly connected to the server 10 and used by an administrator who manages the alarm system 1 . The management device 9 and the server 10 are connected via, for example, a dedicated line or a private line. The management device 9 has a customer management database (customer management DB) 51 . For example, of the user registration information received from SP 8A, the server 10 does not store personal information such as name, address, customer reference number, and telephone number in its own device, and stores the alarm identification information of the gas alarm 2A as personal information. , and transmitted to the management device 9. The management device 9 stores the personal information received from the server 10 in the customer management DB 51 in association with the alarm identification information. In this way, the personal information is stored in the management device 9 separated from the WAN 13, so it is less likely to be leaked to the outside.

(Normal operation of alarm system 1)
Next, normal operation of the alarm system 1 will be described. FIG. 5 is a sequence diagram illustrating an example of normal operation of the alarm system 1. As shown in FIG. FIG. 6 is a diagram showing an example of the initial screen 150. As shown in FIG. In the alarm system 1 , the operating state of the device D installed in the LAN 11 is acquired by the alarm device 2 and transmitted to the server 10 when the alarm device 2 does not detect any abnormality. The server 10 accumulates and stores the operation state of the device D received from the alarm device 2, and when the communication terminal device 8 activates the application 41, the alarm device 2 linked to the communication terminal device 8 acquires the operation state. The communication terminal device 8 displays the operating state of the device D. Furthermore, in the alarm system 1 , the communication terminal device 8 remotely operates the device D using the application 41 . In FIG. 5, the normal operation of the alarm system 1 will be described by taking as an example the case where the gas stove 5, the gas alarm device 2A, the server 10 and the SP 8A communicate with each other.

That is, as shown in FIG. 5, the gas stove 5 ignites and cooks according to the automatic cooking function, for example (S101). The gas stove 5 uses the second communication method to transmit stove operation information including information indicating the ignition state to the gas alarm device 2A (S102).

When the gas alarm device 2A receives the stove operation information using the second communication IF 24, the converter 27 is used to convert the communication method of the stove operation information from the second communication method to the first communication method (S103).

Then, the gas alarm device 2A transmits the stove operation information to the server 10 using the first communication IF 23 (S111). Since the communication method of the stove operation information is converted to the first communication method in S103, the gas alarm device 2A can transmit the stove operation information acquired from the gas stove 5 in the LAN 11 to the server 10 via the WAN 13. .

When the server 10 receives the stove operation information, it stores it in the history DB 32 (S112). In this manner, the server 10 accumulates and stores operation information of the device D such as the gas stove 5 in the history DB 32 .

For example, when the activation icon of the application 41 is tapped, the SP 8A activates the application 41 (S120). When the application 41 is activated, the SP 8A requests the server 10 to generate an initial screen (S121). When the initial screen generation request is received from SP8A, the server 10 uses the arithmetic processing unit 30 to compute initial screen information (S122), and transmits the computed initial screen information to SP8A (S123). When receiving the initial screen information, the SP 8A uses the application 41 to display, for example, the initial screen 150 shown in FIG. 6 on the operation display unit 93 (S124).

Specifically, the calculation method of the initial screen will be described. The remote controller 7A, the second infrared remote controller 7B, and the fire alarm 6 are specified, and the usage history of the specified equipment is read from the history DB 32. The arithmetic processing unit 30 also calculates a heat stroke index indicating the degree of risk of heat stroke based on the room temperature and humidity measured by the first environment sensor 3A and the second environment sensor 3B. The arithmetic processing unit 30 generates initial screen information for displaying the usage history read from the history DB 32 and the calculated heat stroke index on the communication terminal device 8 . The server 10 transmits the initial screen information generated by the arithmetic processing unit 30 to the SP 8A that transmitted the initial screen generation request to the server 10 .

Upon receiving the initial screen information from the server 10, the SP 8A uses the application 41 to display the initial screen 150 shown in FIG.

For example, as shown in FIG. 6, the initial screen 150 includes an environment information display section 151, a stove operation state display section 152, a stove prohibition instruction input section 153, an alarm operation display section 154, and a security bell ringing. It includes an instruction input unit 155 , an air conditioner operation unit 156 and a setting unit 157 .

The environment information display unit 151 displays environment information measured by the first environment sensor 3A and the second environment sensor 3B associated with the SP 8A in the device management DB 31, for example. Display items of the environmental information include, for example, "room temperature", "humidity", "heatstroke index" which is information indicating the degree of risk of heatstroke, and "presence/absence" which is information indicating whether or not there is a person in the room. There is. For example, in the living room column, the room temperature and humidity measured by the first environmental sensor 3A, the heat stroke index indicating the risk of heat stroke calculated based on the room temperature and humidity measured by the first environmental sensor 3A, the first The presence/absence of a person measured by the environment sensor 3A is displayed.

The stove operation state display unit 152 displays, for example, stove operation information indicating the operation state of the gas stove 5 associated with SP8A in the device management DB 31 . The stove operation information displays, for example, either an ignition state indicating that the gas stove 5 is ignited or a fire extinguishing state indicating that the gas stove 5 is extinguished.

The stove prohibition instruction input unit 153 inputs an instruction to set a time and prohibit ignition of the gas stove 5 . Since the time can be arbitrarily set, for example, the user can prohibit the use of the gas stove 5 according to the time when only children and elderly people are at home, which is convenient.

The alarm operation display unit 154 displays, for example, the operation state of the gas alarm 2A associated with SP8A in the equipment management DB 31. FIG. For example, the alarm operation display unit 154 displays "normal" when the gas alarm 2A does not detect gas leakage, and displays "abnormal" when the gas alarm 2A detects gas leakage. be done.

The security bell ringing instruction input unit 155 inputs an instruction to forcibly ring the gas alarm 2A linked to SP8A in the equipment management DB 31 . According to this, for example, when "present" is displayed in the "presence/absence" column of the environment information display section 151 even though no one should be in the house 12, the crime prevention bell ringing instruction input section 155 is tapped. The gas alarm 2A can be sounded by pressing the button. Therefore, the gas alarm device 2A can also be used as a security bell, and the usability of the gas alarm device 2A can be improved.

The air conditioner operation unit 156 is for inputting an instruction to operate the air conditioner. When the air conditioner operation unit 156 is tapped, the initial screen 150 is switched to an air conditioner operation screen 500 (see FIG. 12) for inputting an instruction to remotely control the air conditioner. For example, in the environment information display unit 151, when the column of “heatstroke index” for the living room displays “high” indicating that the risk of heatstroke is high, the user taps the air conditioner operation unit 156 to , the first air conditioner 4A can be operated by remote control.

The setting unit 157 switches the initial screen 150 to a usage condition setting screen for setting usage conditions for using the alarm system 1 . The usage condition setting screen includes, for example, the installation locations of the devices D such as the first environment sensor 3A, the second environment sensor 3B, the first air conditioner 4A, and the second air conditioner 4B, contact information in the event of an abnormality, heat stroke Setting items such as setting whether to automatically turn on the air conditioner when the risk of air pollution is high and addition of sensors are displayed.

Returning to FIG. 5 , for example, when the stove prohibition instruction input section 153 displayed on the initial screen 150 is tapped, the SP 8A accepts the stove prohibition instruction for prohibiting the use of the gas stove 5 and transmits it to the server 10 via the WAN 13. (S131).

When the server 10 receives the stove prohibition instruction, based on the device management DB 31, the server 10 identifies the gas alarm 2A linked to the SP 8A that transmitted the gas stove prohibition instruction to the server 10, and sends the gas alarm 2A via the WAN 13. A stove prohibition instruction is transferred (S132). If the server 10 cannot identify the alarm device 2 linked to SP8A, it notifies SP8A that transmission of the remote operation instruction has failed.

When the gas alarm device 2A receives the stove prohibition instruction from the server 10 via the WAN 13 using the first communication IF 23, the conversion unit 27 is used to switch the communication method of the stove prohibition instruction from the first communication method to the second communication method. It converts to a method (S141). Then, the gas alarm device 2A reads the device identification information of the gas stove 5 to be operated based on the alarm information table 221, connects to the gas stove 5 using the second communication IF 24, and transmits a stove prohibition instruction to the gas stove 5. (S142).

When the gas stove 5 receives the stove prohibition instruction from the gas alarm device 2A (S143), the gas stove 5 executes fire extinguishing processing (S144).

As described above, in the alarm system 1 that notifies the communication terminal device 8 via the WAN 13 of an abnormality that has occurred in the house 12, the communication terminal device 8 connects to the WAN 13 and uses the first communication method. a gas alarm 2A installed in the residence 12; and a plurality of devices D installed in the residence 12 and communicating using a second communication method different from the first communication method. The gas alarm device 2A includes a CPU 21, an abnormality detection unit 25 that detects gas leakage, a speaker 26 that issues an alarm, a first communication IF 23 that is communicatively connected to the WAN 13 using the first communication method, and a second communication IF 24 communicatively connected to a plurality of devices D using a second communication method. For example, the CPU 21 of the gas alarm device 2A uses the second communication IF 24 to acquire device identification information for identifying the devices D from a plurality of devices D, and performs LAN construction processing for constructing the LAN 11 . When performing data communication using the first communication IF 23, the CPU 21 performs communication control processing for converting the data communication method between the first communication method and the second communication method.

In such an alarm system 1, for example, when a gas alarm 2A is installed in a house 12 in which a router is not installed and the device D cannot be connected to the WAN 13, a plurality of devices installed in the house 12 with the gas alarm 2A D is connected using the second communication method, and LAN 11 is constructed. The gas alarm device 2A is connected to the WAN 13 using the first communication IF 23, and converts the data communication method between the first communication method and the second communication method, so that, for example, the gas stove 5 on the LAN 11 and the WAN 13 Enable two-way communication with SP8A above. Therefore, according to the alarm system 1 of this embodiment, for example, the gas stove 5 installed in the house can be easily connected to the WAN 13 simply by installing the gas alarm 2A in the house 12 that does not have an Internet environment.

Further, in the alarm system 1, the device D and the communication terminal device 8, for example, when the gas stove 5 and the SP8A communicate with the gas alarm device 2A via the server 10, the server 10 communicates with the SP8A based on the device management DB31. A communication path is determined by associating with the gas alarm device 2A on a one-to-one basis.

In such an alarm system 1, the gas stove 5 transmits stove operation information to the server 10 via the gas alarm device 2A, the server 10 identifies the SP8A associated with the gas alarm device 2A based on the device management DB 31, The operating state of the gas stove 5 is sent to SP8A (S101-S123). Then, in the alarm system 1, for example, when the SP 8A remotely operates the gas stove 5, the server 10 identifies the gas alarm 2A associated with the SP 8A based on the equipment management DB 31, and relays the identified gas alarm 2A. Then, communication is performed (S131-S144). Therefore, in the alarm system 1, for example, when the gas stove 5 and the SP 8A perform data communication via the gas alarm device 2A, the server 10 determines the communication path based on the device management DB 31, so the load of calculating the communication path is reduced. The gas alarm 2A, the SP8A, and the gas stove 5 can be linked without using the gas alarm 2A or SP8A.

Further, in the alarm system 1, the CPU 21 further uses the second communication IF 24 to perform operation information acquisition processing for acquiring operation information regarding the operation of the device from the device D whose device identification information has been acquired in the LAN construction processing. (S102), in the communication control process, the communication method of the motion information is converted from the second communication method to the first communication method (S103), and the motion information is transmitted to the server 10 using the first communication method (S111). , the server 10 generates notification information to be notified to the communication terminal device 8 based on the operation information received from the alarm device 2 (S122), and based on the device management DB 31, the operation information is associated with the alarm device 2 The communication terminal device 8 is specified, and notification information is transmitted to the specified communication terminal device 8 (S123).

Specifically, in the alarm system 1, the plurality of devices D includes the gas stove 5, the operation information is stove operation information indicating the operating state of the gas stove 5 (S102), and the server 10 receives from the gas alarm 2A If it is determined that the gas stove is ignited based on the stove operation information obtained, initial screen information (an example of notification information) including ignition information indicating the ignition state of the gas stove 5 is generated (S122), and based on the device management DB 31 Then, the SP 8A associated with the gas alarm device 2A that has transmitted the stove operation information is specified, and the initial screen information is transmitted to the specified SP 8A (S123). An initial screen 150 is displayed on the operation display unit 93 to indicate that the

In such an alarm system 1, for example, the server 10 creates initial screen information based on stove operation information received from the gas stove 5 via the gas alarm device 2A, and associates the gas alarm device 2A with the gas alarm device 2A that transmitted the stove operation information. Since the operating status of the gas stove 5 is notified to the supplied SP 8A, the operation of the gas stove 5 can be monitored without imposing a load on the gas alarm 2A for calculating the notification destination of the stove operation information. Development costs can be reduced. By simply installing the gas alarm device 2A, the user can monitor the ignition state of the gas stove 5 from outside when, for example, a child or an elderly person is at home.

Further, in the alarm system 1, when the communication terminal device 8 receives a device remote operation instruction to remotely operate the device D, it transmits the device remote operation instruction to the server 10 via the WAN 13 (S131), and the server 10 When the device remote operation instruction is received, based on the device management DB 31, the alarm device 2 associated with the communication terminal device 8 that has transmitted the device remote operation instruction to the server 10 is identified, and the device remote operation to the identified alarm device 2 is performed. The operation instruction is transmitted via the WAN 13 (S132), and in the communication control process, when the device remote operation instruction is received using the first communication IF 23, the CPU 21 selects the communication method for the device remote operation instruction as the first communication method. to the second communication method (S141), and transmits a device remote operation instruction to the device D to be operated using the second communication IF 24 (S142).

Specifically, in the alarm system 1, when a plurality of devices D includes a gas stove 5, the device remote operation instruction is a usage prohibition instruction to prohibit the use of the gas stove 5, and the server receives the usage prohibition instruction, Based on the device management DB 31, the gas alarm device 2A associated with the SP 8A that has transmitted the use prohibition instruction to the server 10 is identified, and the use prohibition instruction is transmitted to the identified gas alarm device 2A (S132). In the communication control process, when the use prohibition instruction is received using the first communication IF 23, the communication method of the use prohibition instruction is converted from the first communication method to the second communication method (S141), and the second communication IF 24 is used. Then, a usage prohibition instruction is transmitted to the gas stove 5 to disable the use of the gas stove 5 (S142, S143, S144).

In such an alarm system 1, for example, the SP 8A on the WAN 13 transmits a stove prohibition instruction to the gas stove 5 on the LAN 11 via the server 10 and the gas alarm 2A to prohibit the use of the gas stove 5 by remote control. Therefore, according to the alarm system 1 of this embodiment, only by installing the gas alarm device 2A, the gas stove 5 and the SP 8A can be linked and the gas stove 5 can be remotely controlled. In addition, the alarm system 1 allows the user who is out of the house to operate the SP 8A to prohibit the use of the gas stove 5 in the house 12, thereby preventing a fire. That is, for example, when only children or elderly people stay at home, the use of the gas stove 5 can be prohibited from outside to prevent fires.

Further, in the alarm system 1, when the SP 8A receives a ringing instruction to cause the alarm device 2 to generate an alarm, the SP 8A transmits the ringing instruction to the server 10 via the WAN 13. When the server 10 receives the ringing instruction, the device Based on the management DB 31, the alarm device 2 associated with the communication terminal device 8 that transmitted the ringing instruction is specified, the ringing instruction is transmitted to the specified alarm device 2 via the WAN 13, and the CPU 21 controls the first communication IF 23 When a ringing instruction is received using the , the speaker 26 is caused to generate an alarm.

In such an alarm system 1, for example, when the user activates the application 41 and taps the crime prevention bell ringing instruction input section 155 on the initial screen 150 displayed in the SP8A, the server 10 receives the ringing instruction, and the device management DB 31 , the ringing instruction is transferred to the gas alarm device 2A associated with SP8A, causing the gas alarm device 2A to issue an alarm. Therefore, even if the gas alarm 2A does not detect a gas leak, the alarm system 1 issues an alarm in response to the ringing instruction from the SP8A, so that the security of the house 12 can be enhanced.

In the alarm system 1 , the server 10 has a history DB 32 that stores the usage history of the device D, and the device management DB 31 further stores the device D in association with the alarm device 2 . The server 10 accumulates and stores the usage status of the device D received from the gas alarm device 2A in the history DB 32, for example. The SP 8A has an operation display section 93 and an application 41 that controls the operation of displaying information about the device D on the operation display section 93. FIG. When the application 41 is started, the server 10 identifies the device D associated with the SP 8A based on the device management DB 31, reads out the usage history of the identified device D from the history DB 32, and sends it to the SP 8A that started the application 41. It transmits (S122, S123). The SP 8A that started the application 41 displays the initial screen 150 displaying the usage history received from the server 10 on the operation display unit 93 (S124).

According to the alarm system 1, for example, when the SP 8A starts the application 41, the information about the device D in the house 12 in which the gas alarm 2A associated with the SP 8A is installed is displayed on the operation display unit 93 of the SP 8A. , the user does not need to individually specify the device D and check the usage status of the device D, which is convenient.

(Abnormality notification operation of alarm system)
Next, an abnormality notification operation performed by the alarm system 1 will be described. FIG. 7 is a sequence diagram illustrating an anomaly notification operation. FIG. 8 is a diagram showing an example of the gas leak notification screen 200. As shown in FIG. Here, a case where the gas alarm device 2A detects a gas leak will be described as an example.

As shown in FIG. 7, the gas alarm 2A constantly monitors the presence or absence of gas leakage using the abnormality detector 25 (S201).

When the gas alarm device 2A detects gas leakage using the abnormality detection unit 25, the gas leakage detection information is transmitted to the server 10 via the WAN 13 using the first communication IF 23 (S211).

When the server 10 receives the gas leak detection information, it stores the gas leak history in the history DB 32 (S212). Then, the server 10 identifies the SP8A associated with the gas alarm device 2A based on the device management DB31. Then, the server 10 uses the arithmetic processing unit 30 to generate the abnormality notification information for notifying the gas leakage with the SP 8A as the destination, and transmits it to the SP 8A via the WAN 13 (S213).

When the SP 8A receives the abnormality notification information from the server 10, for example, the gas leakage notification screen 200 shown in FIG. 8 is displayed on the operation display unit 93 to notify the user that the gas leakage has occurred (S214). For example, the gas leak notification screen 200 displays a message 201 that reads, "The alarm has been activated!" For example, when the user taps the message 201, as shown in FIG. 7, the SP8A activates the application 41 (S221) and transmits the application activation history to the server 10 (S222). Note that the application 41 may be activated by the user tapping the icon of the application 41 .

When receiving the application activation history, the server 10 determines whether or not there is an activation history for an arbitrary period of time. If there is no activation history for an arbitrary period of time, the server 10 transmits information identifying the gas leak alarm device 2A that transmitted the gas leak detection information to the management device 9 (S223).

When the information specifying the gas leak alarm 2A is received from the server 10, the management device 9 checks the received information against the customer management DB 51 and extracts the address associated with the gas leak alarm 2A. Then, the management device 9, for example, ``There is a gas leak at the house of Mr. XX, XX, XX town, XX city. , and outputs a dispatch command in which the extracted address is set as a dispatch destination (S224). The output of the dispatch order may be displayed on the screen of the management device 9 and may be communicated from the manager to the worker, or may be automatically notified from the management device 9 to the terminal possessed by the worker.

After that, SP8A accepts any operation (S231). For example, the gas leak detection screen shown in FIG. message 204 is displayed. For example, the user can call a predetermined location by operating the telephone numbers 202 and 203 and take countermeasures against gas leaks.

As described above, in the alarm system 1, a plurality of alarm devices 2 are connected to the WAN 13, a plurality of communication terminal devices 8 are connected, and a server 10 is connected to communicate with the alarm device 2. The terminal device 8 communicates via the server 10 . When a gas leak (an example of an abnormality) is detected using the abnormality detection unit 25, the CPU 21 transmits gas leakage detection information (an example of abnormality information), which is information about the gas leakage, to the server 10 using the first communication IF 23. Anomaly information transmission processing is performed (S211). The server 10 has a device management DB 31 that associates the alarm device 2 with the communication terminal device 8. For example, when receiving gas leak detection information from the gas alarm device 2A, the server 10 transmits the gas leak detection information based on the device management DB 31. The SP8A associated with the gas alarm device 2A is identified, and the identified SP8A is notified of the gas leak (S213).

In such an alarm system 1, a plurality of alarm devices 2 and a plurality of communication terminal devices 8 are connected to a WAN 13. One of the plurality of alarm devices 2, ie, a gas alarm 2A, detects a gas leak. is detected, the server 10 identifies the SP 8A associated with the gas alarm device 2A that detected the gas leak and notifies of the gas leak. Therefore, the alarm system 1 can monitor gas leaks in the house 12 by coordinating the gas alarm 2A and the SP 8A without imposing a burden on the gas alarm 2A for calculating the abnormality notification destination.

Further, as described above, the alarm system 1 has a management device 9 directly communicably connected to the server 10, and the management device 9 stores, for example, the address of the user who uses the alarm system 1 at the user's residence 12 has a customer management DB 51 that is stored in association with the gas alarm device 2A installed in . When the server 10 determines, based on the gas leak detection information received from the gas alarm device 2A, that it is necessary to go to the residence 12 in which the gas alarm device 2A that has transmitted the gas leak detection information is installed, the gas leak detection is performed. The management device 9 is notified of information (alarm identification information) identifying the gas alarm 2A that has transmitted the information. When receiving from the server 10 the alarm identification information identifying the gas alarm 2A that has transmitted the gas leak detection information, the management device 9 identifies the gas alarm 2A that has transmitted the gas leakage detection information based on the customer management DB 51. , and outputs a dispatch order in which the specified address is set as a dispatch destination.

In such an alarm system 1, when an abnormality occurs, the management device 9 specifies the address of the house 12 where the alarm device 2 that detected the abnormality is installed and outputs a dispatch order, so that the abnormality can be quickly dealt with. can be done. In addition, since the alarm system 1 stores the user's address in the management device 9 separate from the server 10, the risk of leaking the user's address is dispersed, and the safety of personal information can be ensured.

(Stove use notification operation and fire extinguishing operation)
Next, the stove usage notification operation and fire extinguishing operation of the alarm system 1 will be described. FIG. 9 is a sequence diagram for explaining the operation of monitoring use of the stove. FIG. 10 is a diagram showing an example of the ignition notification screen 300. As shown in FIG. Here, an example will be described in which the operating state of the gas stove 5 is notified to the SP 8A, and the SP 8A extinguishes the gas stove 5 by remote control.

For example, the user activates the application 41 using SP8A and taps the stove prohibition instruction input portion 153 on the initial screen 150 shown in FIG. and can be transmitted to the gas stove 5 via the gas alarm 2A. When the gas stove 5 receives the gas stove prohibition instruction, for example, the ignition operation part of the gas stove 5 is automatically disabled, the power is automatically turned off, or the main valve is automatically closed, thereby making the gas stove 5 unusable. state.

When the user taps the stove prohibition instruction input unit 153 while prohibiting the use of the gas stove 5, the user transmits a stove prohibition release instruction to the gas stove 5 via the server 10 and the gas alarm device 2A to release the stove prohibition instruction. can do. The gas stove 5 becomes ready for use when it receives the instruction to cancel the prohibition of the stove. In addition, the gas stove 5 can be directly operated to disable or enable the use of the gas stove by using the operation part of the device itself.

As shown in FIG. 9, the gas stove 5 transmits ignition information to the gas alarm device 2A using the second communication method when it is ignited (S311) without a stove prohibition instruction (S301) (S312). .

When the gas alarm device 2A receives the ignition information from the gas stove 5 using the second communication IF 24, the conversion unit 27 is used to convert the communication method of the ignition information from the second communication method to the first communication method (S313). Then, the gas alarm device 2A uses the first communication IF 23 to transmit the ignition information obtained by converting the communication method in S313 to the server 10 (S320).

The gas stove 5 and the gas alarm device 2A are prohibited from transmitting ignition information for an arbitrary time after transmitting the ignition information in order to prevent repeated transmission of the ignition information to the server 10 (S315, S316).

When the server 10 receives the ignition information from the gas alarm 2A via the WAN 13, it records the date and time when the gas stove 5 was ignited (ignition history) in the history DB 32 (S321). Then, based on the device management DB 31, the server 10 identifies the SP8A linked to the gas alarm device 2A that transmitted the ignition information, generates ignition notification information that notifies that the gas stove 5 has been ignited, and generates the SP8A. (S322).

Upon receiving the ignition notification information, the SP 8A notifies the user of the state of the stove by displaying an ignition notification screen 300 on the operation display unit 93 as shown in FIG. 10, for example (S323). On the ignition notification screen 300, for example, a message 301 notifying that the stove has been ignited, such as "The stove has been ignited!" A forced fire extinguishing instruction receiving unit 303 for receiving is displayed.

For example, when the forced fire extinguishing instruction reception unit 303 is tapped, the SP 8A activates the application 41 as shown in FIG. 9 (S331), and transmits the application activation history to the server 10 via the WAN 13 (S332).

When receiving the application activation history, the server 10 records it in the history DB 32 (S333). Accordingly, for example, the administrator can confirm that the user has recognized the ignition of the gas stove 5 by accessing the history DB 32 from the management device 9 and referring to the recorded contents.

When SP 8A receives a forced fire extinguishing instruction by tapping the forced fire extinguishing instruction reception unit 303 shown in FIG. 10, it transmits the fire extinguishing instruction to the server 10 via the WAN 13 as shown in FIG. 9 (S341). The server 10 identifies the gas alarm 2A linked to the SP8A based on the equipment management DB 31, further identifies the gas stove 5 linked to the identified gas alarm 2A, and sets the gas stove 5 as the destination. A fire extinguishing instruction is transmitted to the gas alarm device 2A via the WAN 13 (S342).

Upon receiving the fire extinguishing instruction using the first communication IF 23, the gas alarm device 2A uses the conversion unit 27 to convert the communication method of the fire extinguishing instruction from the first communication method to the second communication method (S351). Then, the gas alarm device 2A reads the device identification information of the gas stove 5 set as the destination of the fire extinguishing instruction from the alarm information table 221, connects to the gas stove 5 using the second communication IF 24, and instructs the gas stove 5 to extinguish the fire. is transmitted using the second communication method (S352).

Upon receiving the extinguishing instruction from the gas alarm device 2A, the gas stove 5 performs extinguishing processing and notifies by voice that the extinguishing has been extinguished (S353). The fire extinguishing process is performed, for example, by automatically operating a fire extinguishing button or forcibly turning off the power. Since the gas stove 5 is extinguished against the intention of the person who ignited it, it is possible to prevent a third party from erroneously recognizing the failure of the gas stove 5 by announcing that the fire has been extinguished by voice.

As described above, in the alarm system 1, the plurality of devices D include the gas stove 5, and the operation information acquired from the gas stove 5 by the gas alarm device 2A and transmitted to the server 10 is ignition information indicating the ignition state of the gas stove 5. (an example of stove operation information). When the server 10 determines that the gas stove 5 is ignited based on the ignition information received from the gas alarm device 2A, the server 10 generates ignition notification information (an example of notification information) indicating the ignition state of the gas stove 5, and manages the equipment. Based on the DB 31, the SP 8A associated with the gas alarm device 2A that transmitted the ignition information is identified, and the ignition notification information is transmitted to the identified SP 8A (S322). Having received the ignition notification information, the SP 8A displays an ignition notification screen 300 indicating that the gas stove 5 is being ignited on the operation display unit 93 (S323).

Such an alarm system 1, for example, creates ignition notification information indicating the ignition state of the gas stove 5 based on the ignition information received by the server 10 from the gas stove 5 via the gas alarm device 2A, Since the SP 8A associated with the gas alarm that sent the information is notified, the ignition state of the gas stove 5 can be monitored without imposing a load on the gas alarm 2A for calculating the notification destination of the ignition notification information. The hardware development cost of the alarm device 2A can be reduced.

Moreover, as described above, in the alarm system 1 , the plurality of devices D includes the gas stove 5 , and the device remote operation instruction is a fire extinguishing instruction to extinguish the gas stove 5 . When the server 10 receives the fire extinguishing instruction (S341), the server 10 identifies the gas alarm 2A associated with the SP 8A that transmitted the fire extinguishing instruction to the server 10 based on the equipment management DB 31, A fire extinguishing instruction is transmitted (S342). When the CPU 21 receives a fire extinguishing instruction using the first communication IF 23 in the communication control process, the CPU 21 converts the communication method of the fire extinguishing instruction from the first communication method to the second communication method (S351), and sends the second communication IF 24. is used to transmit a fire extinguishing instruction to the gas stove 5 to cause the gas stove 5 to extinguish the fire (S352, S353).

For example, when the gas stove 5 is ignited while the user is out, the user can operate the SP8A to extinguish the gas stove 5 in the house 12, thereby preventing a fire. can do.

(Heat stroke monitoring operation)
Next, the heat stroke monitoring operation of the alarm system 1 will be described. FIG. 11 is a sequence diagram illustrating an example of the heat stroke monitoring operation. Here, the living room of the house 12 will be described as an example.

The first environmental sensor 3A detects and monitors the room temperature, humidity, presence of people, etc. in the living room (S401). The first environmental sensor 3A transmits sensor data including room temperature and humidity to the gas alarm device 2A at arbitrary intervals (for example, every 5 minutes) using the second communication method (S411).

Upon receiving the sensor data using the second communication IF, the gas alarm device 2A uses the converter 27 to convert the sensor data communication method from the second communication method to the first communication method (S412). The gas alarm device 2A then transmits the sensor data to the server 10 using the first communication IF 23 (S421).

When the server 10 receives the sensor data from the gas alarm device 2A via the WAN 13, it stores it in the history DB 32 (S422). Then, the server 10 uses the arithmetic processing unit 30 to calculate a heatstroke index indicating the degree of risk of heatstroke based on the received sensor data. The heat stroke index is calculated in three stages, for example, "high" for a high risk of heat stroke, "medium" for a high risk of heat stroke, and "low" for a low risk of heat stroke.

The server 10 records the heat stroke index calculated by the arithmetic processing unit 30 in the history DB 32 in association with the gas alarm 2A and the first environment sensor 3A (S424). Then, based on the device management DB 31, the server 10 identifies the SP 8A linked to the gas alarm 2A that transmitted the environmental information of the first environmental sensor 3A, and generates a heat stroke risk level based on the heat stroke index. A notification is sent to SP8A via WAN13 (S425).

SP8A will display a heat stroke danger level on the operation display part 93, if a notification of a heat stroke danger level is received. When the application 41 is activated (S431), the SP 8A transmits the application activation history to the server 10 (S432). If there is no application activation history for an arbitrary period of time, the server 10 transmits to the management device 9 information identifying the gas alarm device 2A that transmitted the sensor data used when calculating the heat stroke index (S433).

When the management device 9 receives the alarm device identification information specifying the gas leak alarm device 2A from the server 10, the management device 9 checks the received alarm device identification information against the customer management DB 51 and extracts the address associated with the gas leak alarm device 2A. do. Then, for example, the management device 9 reads, "There is a high risk of heat stroke in the living room of Mr. Please," and outputs a dispatch command in which the extracted address is set as the dispatch destination (S434).

Although omitted in FIG. 11, when the application 41 is activated, the server 10 transmits the initial screen 150 created by the arithmetic processing unit 30 to the SP8A. The SP 8A causes the operation display unit 93 to display the initial screen 150 received from the server 10, as shown in FIG. 6, for example. At this time, on the initial screen 150, the sensor data of the first environment sensor 3A and the second environment sensor 3B received by the server 10 from the gas alarm device 2A are reflected in the display contents of the environment information display section 151. FIG.

For example, in the living room column of the environment information display section 151 displayed on the initial screen 150, based on the sensor data measured by the first environment sensor 3A, the room temperature item is "36°C" and the humidity item is "28°C". %”, “High” in the heat stroke index item, and “Present” in the presence/absence item. Thereby, even if the user is outside the house 12, the user can know that the person in the living room of the house 12 is at high risk of suffering from heat stroke. Therefore, the user arbitrarily operates the SP8A, such as by tapping the air conditioner operation section 156 on the initial screen 150 to switch the display screen or by calling home (S441). This can prevent people in the living room from getting heatstroke or aggravating heatstroke.

As described above, the alarm system 1 includes the first environment sensor 3A with which a plurality of devices D can measure room temperature and humidity, and the first environment sensor 3A transmits to the server 10 via the gas alarm 2A. The operation information is sensor data (an example of environmental information) including room temperature and humidity measured by the first environment sensor 3A. The server 10 calculates the risk of heat stroke based on the sensor data received from the gas alarm 2A, generates a heat stroke risk level (an example of notification information) including the risk of heat stroke (S423), Based on the device management DB 31, the SP 8A associated with the gas alarm 2A that sent the sensor data is specified, and the heatstroke danger level is sent to the specified SP 8A (S425). Having received the heat stroke risk level, SP8A displays the heat stroke risk level (S426).

In such an alarm system 1, the server 10 calculates the risk of heat stroke based on the sensor data received from the first environmental sensor 3A via the gas alarm 2A, and calculates the calculated risk of heat stroke as follows: The SP 8A associated with the transmitted gas alarm device 2A is notified of the sensor data used when calculating the degree of risk of heat stroke. Therefore, according to the alarm system 1, it is possible to notify the user who is outside the house 12 of the risk of heat stroke by the resident only by installing the gas alarm 2A.

In addition, for example, the SP 8A registers a contact address when the risk of heat stroke is high, for example, a home phone number in the application 41, and sends a heat stroke risk level notification indicating that the risk of heat stroke is high. When received, the contact information registered in the application 41 may be displayed along with the degree of risk of heatstroke. In this case, tapping on a contact will automatically contact that contact, thereby reducing the trouble of searching for a contact when taking measures against heatstroke. For example, the contact information may be registered in advance in the management device 9 instead of the application 41, and the server 10 may read it from the management device 9 in response to a request from the SP 8A and display it on the SP 8A.

(Air conditioner remote control operation)
Next, the air conditioner remote control operation of the alarm system 1 will be described. FIG. 12 is a diagram showing an example of an air conditioner operation screen 500. As shown in FIG. FIG. 13 is a sequence diagram illustrating air conditioner remote control. Here, a case where a living room with a high risk of heat stroke is cooled by the first air conditioner 4A will be described as an example.

For example, as shown in FIG. 13, when the user sees the display of the heatstroke risk level (S501) and activates the application 41 (S511), the application activation history is transmitted from SP8A to the server 10. FIG. Note that the application 41 may be activated by tapping the icon of the application 41 regardless of the heatstroke risk level notification.

Although not shown in FIG. 13, the SP 8A causes the operation display unit 93 to display an initial screen 150 shown in FIG. 6 after the application 41 is activated. For example, when the user confirms on the initial screen 150 that there is a person in the living room whose heat stroke index is "high" and taps the air conditioner operation unit 156, SP8A displays the initial screen displayed on the operation display unit 93. 150 is switched to the air conditioner operation screen 500 shown in FIG.

The air conditioner operation screen 500 shown in FIG. 12 includes a display column 501 for displaying room temperature, humidity, and heat stroke index, an on/off setting column 502 for setting ON/OFF of the air conditioner, and an operation to switch operation between cooling and dehumidifying. An operation switching reception field 503 for receiving, a room temperature setting field 504 for setting a set room temperature, an air volume setting field 505 for setting a set air volume, and a selection field 506 for selecting an air conditioner are displayed. The selection field 506 displays, for example, air conditioners registered by the user via the setting unit 157 of the initial screen 150, and if there are multiple registered air conditioners, the air conditioners are displayed so as to be selectable.

For example, the user inputs “cooling” in the operation switching reception field 503 , “25° C.” in the room temperature setting field 504 , “strong” in the air volume setting field 505 , and “living air conditioner” in the selection field 506 , and the on/off setting field 502 , tap "ON". Then, as shown in FIG. 13, the SP 8A receives an air conditioner remote operation instruction for starting the first air conditioner 4A, and transmits an air conditioner remote operation instruction for operating the first air conditioner 4A to the server 10 via the WAN 13 ( S521).

When the server 10 receives the air conditioner remote control instruction, it records it in the history DB 32 (S522). Then, based on the equipment management DB 31, the server 10 identifies the gas alarm device 2A linked to the SP8A that transferred the air conditioner remote operation instruction, and transfers the air conditioner remote operation instruction received from the SP8A to the gas alarm device 2A. (S523).

When the gas alarm device 2A receives the air conditioner remote operation instruction using the first communication IF 23, the conversion unit 27 is used to convert the communication method of the air conditioner remote operation instruction from the first communication method to the second communication method (S531). ). Then, the gas alarm device 2A reads the device identification information of the first infrared remote controller 7A corresponding to the first air conditioner 4A to be operated based on the alarm information table 221, and uses the second communication IF 24 to read out the device identification information of the first infrared remote controller 7A. 7A, and transmits an air conditioner remote control instruction to the first infrared remote controller 7A (S532).

When the first infrared remote controller 7A receives the air conditioner remote operation instruction from the gas alarm 2A, it transmits an infrared signal for turning on the air conditioner according to the content of the air conditioner remote operation instruction to the first air conditioner 4A (S533). As a result, the first air conditioner 4A operates according to the setting content of the air conditioner remote operation instruction, and lowers the room temperature of the living room.

As described above, in the alarm system 1, the plurality of devices D includes the first air conditioner 4A and the first infrared remote controller 7A for operating the first air conditioner 4A, and the device remote operation instruction is sent to the first air conditioner 4A. It is an air conditioner remote control instruction that causes the air conditioner to operate. When the server 10 receives the air conditioner remote operation instruction (S521), the server 10 identifies the gas alarm 2A associated with the SP 8A that transmitted the air conditioner remote operation instruction to the server 10 based on the device management DB 31, An air conditioner remote control instruction is transmitted to the alarm device 2A (S523). In the communication control process, when an air conditioner remote operation instruction is received using the first communication IF 23, the CPU 21 converts the communication method of the air conditioner remote operation instruction from the first communication method to the second communication method (S531). 1, an air conditioner remote control instruction is transmitted to the infrared remote controller 7A to cause the first air conditioner 4A to perform cooling operation (S532, S533).

Such an alarm system 1 can operate the SP 8A to cause the first air conditioner 4A to perform a cooling operation when, for example, a person at home in the living room is at high risk of suffering from heat stroke. , It is possible to prevent heat stroke and aggravation of heat stroke in the home.

It should be noted that the present invention is not limited to the above embodiments, and can be applied in various ways.

For example, if the first air conditioner 4A can directly communicate with the gas alarm device 2A using the second communication method, as shown in FIG. may be directly transmitted (S551) to turn on the first air conditioner 4A (S552). However, when the gas alarm device 2A operates the first air conditioner 4A using the first infrared remote controller 7A as in the above embodiment (see FIG. 13), the first air conditioner 4A may be provided with a communication function, for example. Since there is no need to change the configuration of 4A, the communication path necessary for remote control of the air conditioner can be easily secured simply by installing the gas alarm 2A.

For example, as shown in FIG. 14, the operating state of the first air conditioner 4A may be transmitted to the server 10 via the gas alarm device 2A. That is, when the first air conditioner 4A is turned off (S561), the first air conditioner 4A transmits to the gas alarm device 2A off information indicating that it is in the off state (S562). When the gas alarm device 2A receives the OFF information using the second communication IF 24, it uses the conversion unit 27 to convert the communication method of the OFF information from the second communication method to the first communication method (S563), and transmits the OFF information. It is transmitted to the server 10 (S564). When the server 10 receives the OFF information via the WAN 13, it records it in the history DB 32 (S565). This allows the user to recognize that the first air conditioner 4A has been turned off against the user's intention.

For example, as shown in FIG. 15, the heat stroke sequence (S581) is performed between the first environment sensor 3A, the gas alarm device 2A and the server 10 in the same manner as S411 to S412 and S421 to S424 in FIG. If there is a high risk of air conditioner remote control, the server 10 may transmit an air conditioner remote control instruction to the first air conditioner 4A or the first infrared remote controller 7A via the gas alarm 2A. For example, in the heatstroke sequence (S581), if the server 10 determines that there is a high risk of heatstroke in the living room of the house 12 based on the room temperature and humidity measured by the first environment sensor 3A, the first air conditioner 4A automatically turns on. The control is set to ON to instruct to turn on the first air conditioner 4A (S591). That is, it generates an air conditioner remote control instruction to cause the first air conditioner 4A to perform cooling. Then, the server 10 stores in the history DB 32 that the first air conditioner 4A is ON (S592). Then, the server 10 transmits an air conditioner remote control instruction to operate the first air conditioner 4A to the gas alarm device 2A that transmitted the environmental information used when calculating the degree of risk of heatstroke in S581 (S593). The gas alarm device 2A converts the communication method of the air conditioner remote operation instruction (S601), and transmits the air conditioner operation instruction to the first air conditioner 4A or the first infrared remote controller 7A (S602). The first air conditioner 4A executes the air conditioner operation sequence according to the air conditioner remote operation instruction received from the gas alarm 2A or the infrared signal transmitted by the first infrared remote controller 7A according to the air conditioner remote operation instruction to cool the living room (S603). ). According to this, the server 10 operates the first air conditioner 4A without waiting for the operation of the communication terminal device 8, so it is possible to quickly take measures against heatstroke.

For example, the risk of heatstroke may not be monitored. However, by performing the process of monitoring the degree of risk of heat stroke, for example, it is possible to prevent heat stroke from becoming severe in an elderly parent living in a distant place.

For example, when there is a risk of heatstroke, the process of starting the air conditioner by remote control from SP8 may not be performed. However, by performing such processing, the user can quickly take countermeasures against heat stroke for a person in a distant place, and suppress the severity of heat stroke.

For example, use of the gas stove 5 may not be monitored. However, by monitoring the use of the gas stove 5, fires can be prevented.

For example, monitoring whether or not the gas stove 5 is ignited from outside the house, and when the gas stove 5 is ignited, extinguishing the gas stove 5 by remote control from the SP 8 or prohibiting the use of the gas stove 5 are performed. It doesn't have to be. However, by performing such a process, for example, it is possible to recognize from outside the house that a person who does not want to use the gas stove 5 has ignited the gas stove 5, and extinguish the fire. It can be prevented.

For example, the management device 9 may store the user's address in association with the alarm device 2, and may not output a dispatch order when an abnormality occurs or when the risk of heat stroke is high. However, by doing so, countermeasures against abnormalities and heatstroke can be promptly taken.

For example, although the customer management DB 51 is provided in the management device 9 in the above embodiment, the customer management DB 51 may be provided in the server 10 . However, by providing the customer management DB 51 on the management device 9 side, the security for protecting personal data can be enhanced.

For example, the application 41 may acquire the usage history of the device D from the server 10 , generate the initial screen 150 , and display it on the communication terminal device 8 .

For example, the presence or absence of a person may be detected by a human sensor provided separately from the first environment sensor 3A and the second environment sensor 3B.

For example, the anomaly detector 25 may detect a plurality of anomalies such as gas leak and carbon monoxide, gas leak and fire, gas leak and fire and carbon monoxide.

For example, as shown in FIG. 16, the gas alarm device 2A may be provided with a remote controller 94 for operating an air conditioner and an environment information acquiring section 95 for acquiring environment information including at least one of room temperature and humidity. In this case, the alarm system 1 transmits to the server 10 the environment information acquired by the environment information acquisition unit 95 of the gas alarm device 2A. When the server 10 determines that the risk of heat stroke is high based on the received environmental information, the server 10 notifies the SP 8A associated with the gas alarm 2A in the equipment management DB 31 that the risk of heat stroke is high. Send information. Therefore, the alarm system 1 uses the environment information acquisition unit 95 of the gas alarm device 2A to The risk of heatstroke in the residence 12 can be monitored. Further, when the gas alarm 2A receives an air conditioner remote control instruction from the SP 8A via the server 10 to cause the first air conditioner 4A to perform cooling operation, the gas alarm 2A uses the remote control 94 to cause the first air conditioner 4A to perform the cooling operation. Therefore, the alarm system 1 can operate the first air conditioner 4A and the second air conditioner 4B simply by installing the gas alarm 2A even in a house 12 that does not have the first infrared remote controller 7A or the second infrared remote controller 7B compatible with the second communication method. It is possible to prevent the resident from suffering from heat stroke or from aggravating heat stroke. The same applies when the server 10 determines that the risk of heat stroke is high and transmits an air conditioner operation instruction to the gas alarm device 2A without waiting for the operation of the communication terminal device 8. FIG. Note that either one of the remote control 94 and the environment information acquisition section 95 may be provided in the alarm device 2 . When the remote controller 94 is provided in the alarm device 2, the first environment sensor 3A and the second infrared remote controller 3A corresponding to the second communication method can be operated without the first infrared remote controller 7A and the second infrared remote controller 7B corresponding to the second communication method. The degree of risk of heat stroke can be monitored for each room in which the environment sensor 3B is installed, and the air conditioners installed in rooms with a high degree of risk of heat stroke can be operated. Further, when the environmental information acquisition unit 95 is provided in the gas alarm device 2A, the number of times the gas alarm device 2A communicates with the first environment sensor 3A and the second environment sensor 3B using the second communication method is reduced, 2 can be reduced.
