Description

The present invention relates to an alarm linkage system that links an alarm system including a plurality of interlocked alarms installed in a plurality of dwelling units using a network of a gas management system that remotely performs automatic meter reading of a gas meter. About.

  Conventionally, alarm devices that detect and warn of abnormalities such as fires and gas leaks in homes have become widespread. Of these, residential fire alarms are referred to as residential alarms.

  For example, in such a house alarm device, a sensor unit and an alarm unit are integrally provided in the house alarm device, and when a fire is detected from the detection signal of the sensor unit, a fire alarm of a predetermined pattern is output from the alarm unit. Because it is possible to perform fire monitoring and alarming with a single residential alarm without requiring dedicated receiving equipment, it is easy to install and inexpensive, and it has become widespread due to the obligatory installation in ordinary houses. ing.

  In addition, by communicating between multiple home alarms, we propose a linked alarm system that outputs fire alarms in conjunction with other home alarms when any home alarm outputs a fire alarm. Has been put to practical use.

  In such an interlock type alarm system, when a fire is detected by a home alarm, the home alarm device that detected the fire has a predetermined pattern of fire alarm sound including a message, for example, “Woo Woo Fire Alarm Confirm that it has been activated ", while the alarm device linked to it outputs a fire alarm sound such as" Please confirm that another fire alarm has been activated. "

  On the other hand, in recent years, a gas management system called a new version of a centralized monitoring system has been introduced, which is equipped with a smart meter for gas that builds a wireless sensor network in the gas meter and enables remote automatic meter reading by a data center. It is being advanced.

In such a gas management system, it is possible to connect a home communication adapter for short-range wireless communication to a gas meter, and connect the home communication adapter to a wide area wireless communication network or a third generation mobile communication network known as 3G Connected to a wide-area communication adapter, automatic meter reading can be performed remotely by transmitting and processing meter reading information read from a gas meter in response to periodic meter reading requests from a server provided in the data center .

[Configuration of alarm linkage system]
FIG. 1 shows a schematic configuration of an alarm linkage system according to the present invention in a case where an alarm system installed in two houses (dwelling unit, residence) is linked using a network of a gas management system that performs automatic meter reading. It is explanatory drawing. Such alarm linkage systems include, for example, an elderly residence and its manager residence, a care recipient residence and a caregiver residence, a nursery and the parents' child residence, a school and student residence, a workplace and home. It can be used in various ways between multiple buildings in the same facility.

  In FIG. 1, a house 12-1 is, for example, a house of a parent household, and a house 12-2 is a house of a child household, both of which are built apart in different places. In a warning area (monitoring area) such as the kitchen, living room, main bedroom, and staircase of the house 12-1, a wireless interlocking house alarm (residential fire alarm) 10-11 that detects and interlocks with a fire. 10-12 are installed, and an interlocking type alarm system is constructed. In addition, a wireless interlocking house alarm (residential fire alarm) that also detects fires and interlocks alarms in monitoring areas such as kitchens, living rooms, children's rooms, main bedrooms, and staircases in the house 12-2. Unit) 10-21 and 10-22 are installed to construct an interlocking alarm system.

  In addition, although the house 12-1 and 24-1 have illustrated the case where two residence warning devices are each installed for convenience of explanation, the number (number of interlocking units) of the alarm devices constituting each alarm system is arbitrary. Thus, it may be one unit or a plurality of units of three or more, and an appropriate number can be installed as required for each alarm system. In addition, hereinafter, the house alarm devices 10-11 to 10-22 are collectively referred to as the house alarm device 10 without being distinguished from each other.

  The home alarm device 10 has a function of wirelessly transmitting and receiving interlocking signals to each other, and monitors the presence or absence of a fire in the corresponding monitoring area in each place of the house. If a fire has occurred in the house 12-1, for example, the residence guard 10-11 detects the fire and starts an alarm. Detecting this fire and initiating an alarm is referred to as “reporting” at the home alarm.

  When the home alarm device 10-11 issues a report, the home alarm device 10-11 functions as an interlock source, and wirelessly transmits a fire interlocking signal to another home alarm device 10-12 as an interlock destination. When another fire alarm 10-12 effectively receives the fire interlock signal from the interlocking house alarm 10-11, it performs an alarm operation as an interlock destination by an alarm sound and an alarm display.

  Here, when the group code included in the received interlocking signal matches the group code registered in the memory and the signal content is normally recognized, the resident alarm 10 confirms that the interlocking signal has been effectively received. I try to detect it. Furthermore, the resident guard 10 that has effectively received the interlocking signal relays the interlocking signal as necessary. The group code is set as a unique code for each alarm system, and each residential alarm can identify and process only the interlocking signal related to the alarm system to which it belongs.

  As an alarm operation of the home alarm device 10-11 that is the linkage source, for example, a fire alarm sound by a voice message such as “Please confirm that the Woo Woo fire alarm has been activated” is output. On the other hand, in the linked home alarm device 10-12, a fire alarm sound by a voice message such as “Please confirm that another fire alarm device has been activated” is output.

  Moreover, as an alarm display accompanying the fire alarm of the home alarm device 10-11 that is the interlocking source, for example, an LED is lit. On the other hand, in the interlocking residence police device 10-12, the LED is blinked. As a result, the alarm display by the LED in the interlock source alarm and the interlock destination alarm can be distinguished.

  When the home alarm device 10 detects a fire, the home alarm device 10 transmits a fire-linked signal according to a predetermined first wireless communication protocol to other home alarm devices belonging to the same alarm system. Moreover, the home alarm 10 receives the fire interlocking signal transmitted from the other home alarms belonging to the same alarm vision system according to the first wireless communication protocol. The basic alarm interlocking operation in each alarm system is realized by such a transmission / reception function of the residential alarm 10.

  The transmission and reception by the first wireless communication protocol in the home guard 10 is, for example, STD-30 (radio equipment of a low power security system radio station) known as a standard of a specific low power radio station of 400 MHz band in Japan. Standards) or STD-T67 (standard specifications for specific low-power radio station telemeters, telecontrol and data transmission radio equipment). Of course, when used outside Japan, the content conforms to the standard of the assigned radio station in that region. The transmission power of the residential police device 10 compliant with the specified low power radio station is 10 mW or less for <STS-30, 10 mW or less or 1 mW or less for STD-T67, and the line-of-sight communication distance is approximately 100 meters. It becomes.

  As a device for constructing a gas management system for performing management and control including automatic meter reading of the gas meter 14 in the house 12-1, a home communication adapter 16-11 and a home communication adapter 16-11 connected to the gas meter 14 by signal lines. A wide area communication adapter 18-1 connected to a signal line is installed, and a home communication adapter 16-12 for cooperation is connected to the dwelling guard 10-11 via a signal line.

  Similarly, in the house 12-2, as a device for constructing a gas management system, a home communication adapter 16-21 connected to the gas meter 14 via a signal line, and a wide area communication adapter 18 connected via a signal line to the home communication adapter 16-21. -2 is installed, and further, an in-home communication adapter 16-22 for cooperation is connected to the residence police device 10-21 through a signal line.

  Hereinafter, the home communication adapters 16-11 to 16-22 and the wide area communication adapters 18-1 and 18-2 are collectively referred to as the home communication adapter 16 and the wide area communication adapter 18 without being distinguished from each other. Further, in the present embodiment, the home communication adapters 16-12 and 16-22 are connected to one of the residence police devices 10-11 and 10-21 installed in the houses 12-1 and 12-2, respectively. However, for example, the home communication adapter 16 may be connected to all the other residential alarms 10.

  The gas meter 14 is a gas meter suitable for city gas in the case of city gas supplied by gas piping, and a gas meter compatible with liquefied natural gas in the case of liquefied natural gas (LP gas) supplied by a gas cylinder. To do.

  The home communication adapter 16 transmits and receives signals according to a predetermined second wireless communication protocol. Further, signals are transmitted and received between the home communication adapter 16 and the gas meter 14 connected to the signal line according to a predetermined bus communication protocol.

  The wide-area communication adapter 18 is provided with a mobile phone communication function, and a gas management provided in a data center of a gas company via the mobile phone base stations 20-1 and 20-2, the mobile phone network 22 and the Internet 24. Signals are transmitted to and received from the server 28.

  The wide area communication adapter 18 is provided with a wireless LAN communication function, and is connected to a gas management server 28 provided in a data center of a gas company via an access point 25, a public wireless LAN communication network 26, and the Internet 24. Send and receive signals. The gas management server 28 is provided with a function of the gas meter reading processing unit 34 and a database 36.

  The mobile phone communication function and the wireless LAN communication function of the wide area communication adapter 18 are switched and used corresponding to the service area of the mobile phone network 22 or the public wireless LAN communication network 26. In the following description, a case where the mobile phone network 22 is used by the mobile phone communication function of the wide area communication adapter 18 will be described as an example.

  An abnormality monitoring server 30 is provided so as to be able to communicate with the Internet 24. The abnormality monitoring server 30 is provided with the function of the cooperation control unit 38 and the database 40.

  Here, the home communication adapter 16 forms an internal network in each house according to the second wireless communication protocol, and the wide area communication adapter 18 uses the external mobile phone network 22 or the public wireless LAN communication network 26 and the Internet according to the third communication protocol. 24 forms an external network of gas management systems that couple to 24.

  Here, the case where alarm devices are linked in the alarm system is called “linkage”, and the case where different systems are linked is called “linkage”. In addition, as a result of cooperation, cooperation within the cooperation destination system may be referred to as “cooperation cooperation”.

  In addition, a signal transmitted and received between alarm devices in an alarm system is referred to as a “linked signal”, and a signal transmitted and received between different systems is referred to as a “linked signal”. The former interlock signal includes a fire interlock signal, a fire recovery interlock signal, an alarm stop interlock signal, and a failure interlock signal. The latter interlock interlock signal includes a fire interlock signal, a fire recovery interlock signal, and an alarm stop interlock signal. There are signals, failure cooperation interlocking signals, etc., and these correspond to the claims.

  Further, as a signal transmitted / received between the home communication adapter 16, the wide area communication adapter 18, the gas management server 28, and the abnormality monitoring server 30 of the gas management system, for example, a “packet signal” composed of a header portion and a data portion is used. is doing. Therefore, in the following embodiments, the fire cooperation interlocking signal, the fire recovery cooperation interlocking signal, the alarm stop cooperation interlocking signal, and the failure cooperation interlocking signal are represented by the fire cooperation interlocking packet signal, the fire recovery cooperation interlocking packet signal, and the alarm stop cooperation interlocking packet signal. And a failure cooperation interlocking packet signal.

  As the second wireless communication protocol for transmitting and receiving signals by the in-home communication adapter 16, for example, a wireless communication protocol for a gas smart meter that is planned to be incorporated into the standard of IEEE 802.15.4g is used.

  The outline of the second wireless communication protocol is as follows. In Japan, the frequency used is 950.1 to 955.7 MHz, and the transmission power is 1 mW. Therefore, it conforms to the standard of the specific low-power radio station, which is the same as that of the residential alarm 10.

  The home communication adapter 16 is assigned a 14-byte address, and the size of the packet signal transmitted at one time is fixed at 128 bytes. The address assignment is also performed for the wide area communication adapter 18 constituting the gas management system, the gas management server 28, and the abnormality monitoring server 30 used for cooperation with the gas management system. Addresses required for the destination ID and the transfer source ID and transfer destination ID used for relay are set.

  In addition, about the gas meter 14 and the residential alarms 10-11 and 10-21, since it becomes an external apparatus seeing from the near field wireless network (internal network) by the home communication adapters 16-1 and 16-2, address allocation is performed. Without identification, identification is performed by a port number or the like that identifies the interface circuit unit to which the bus signal line is connected. Of course, a 128-byte address may be assigned to the gas meter 14 and the residential alarms 10-11 and 21 as well as the home communication adapter 16.

  Communication between a plurality of home communication adapters 16 performs multistage relay transmission known as multihop transmission. The maximum number of hops (maximum number of relays) of multihop transmission is set to 5 times, for example.

  In each of the in-home communication adapters 16-11 to 16-22, configuration information in which IDs (identification information) of adapters capable of communication corresponding to the number of relays are registered in advance in the memory, and the packet signal to be transmitted is stored. Since the header part is provided with the transfer source ID and the transfer destination ID for relaying in addition to the transmission source ID and the destination ID, the adapter ID that can reach the destination ID from the configuration information with the minimum number of times is sequentially transferred. Set to, and relay the packet signal.

  In addition, the home communication adapter 16 of the present embodiment is operated by a battery power source, and performs intermittent transmission and reception called a beacon method in order to guarantee a battery life exceeding, for example, 10 years. In the beacon method, for example, a beacon signal of several milliseconds is intermittently transmitted from the receiving adapter at a cycle of 3 to 4 seconds, and the transmitting adapter transmits a packet signal at the timing when the beacon signal is received. The data transmission speed is as low as 100 kilobits / second, for example, but there is no problem because the collection of gas meter reading data is about several times a month.

  As a second wireless communication protocol used in the gas management system, for example, Z-Wave (R) using a frequency of 900 MHz assigned to RFID (Radio Frequency IDentification “abbreviation of radio wave identification”), that is, 950 to 957 MHz. ) Or ZigBee (R), a short-range wireless communication protocol for sensor networks can also be used.

  In particular, Z-Wave (R) is a wireless communication protocol developed for home automation, uses an intelligent mesh network topology, does not have a master node, for example, nodes A, B, and C are arranged. Even if the node A and the node C are at a distance that cannot communicate with each other, the message can be transmitted from the node A to the node C by the relay function of the node B located between them. This is suitable as the second wireless communication protocol.

  In ZigBee (R), which is provided as a short-range wireless communication standard for home appliances, a node that functions as a single coordinator and a plurality of nodes that function as routers are arranged in a star shape centering on the coordinator. In the case of only a node functioning as a router, a peer-to-peer (Pear to Peer) network topology can be constructed.

  The short-range wireless communication in the 900 MHz band such as Z-Wave (R) and ZigBee (R) is set to 1 mW or less as in the case of the specific low-power wireless station, and the line-of-sight communication distance is about 100 meters when the power is 1 mW. It becomes.

  On the other hand, between the gas meter 14 and the home communication adapter 16, between the home communication adapter 16 and the wide area communication adapter 18, and between the home alarm adapter 10 and the home communication adapter 16 for cooperation are connected by a bus signal line. Packet signals are transmitted and received according to the bus communication protocol.

  The packet signal transmitted / received according to the bus communication protocol conforms to, for example, the packet signal transmitted / received according to the second wireless communication protocol, the packet signal size is 128 bytes, and the header portion includes a transmission source ID, a destination ID, and a transfer. The original ID and the transfer destination ID are included. Further, the port number of the transmission side interface circuit unit is set in the transmission source ID, the port number of the reception side interface circuit unit is set in the destination ID, and the transfer source ID and the transfer destination ID used for relay become empty.

  The wide area communication adapter 18 is a third generation mobile communication known as 3G communication, and has a mobile phone communication function conforming to the IMT-2000 (International Mobile Telecommunications 2000) standard defined by the International Telecommunications Union (ITU). Packet signals can be transmitted / received to / from the gas management server 28 and the abnormality monitoring server 30 via the co-base stations 20-1 and 20-2, the mobile phone network 22 and the Internet 24.

  The wide area communication adapter 18 also has a wireless LAN communication function. Packets are exchanged between the gas management server 28 and the abnormality monitoring server 30 on the Internet 24 via an access point 25 provided in the public wireless LAN communication network 26. Signals can also be sent and received.

  The gas management system automatically performs gas meter reading by the gas meter processing unit 34 provided in the gas management server 28. For gas meter reading, the database 36 of the gas management server 28 stores, for example, user information, gas usage, billing information, etc. using the ID of the gas meter 14 installed in the houses 12-1 and 12-2 as an index. .

  Taking the house 12-1 as an example, the gas management server 28 sends the meter reading request packet signal to the Internet once a week, for example, with the address of the home communication adapter 16-11 connected to the gas meter 14 of the house as the destination ID. 24, to the home communication adapter 16-11 via the mobile phone network 22, the mobile phone base station 20-1, and the wide area communication adapter 18-1.

  The in-home communication adapter 16-11 that has detected the effective reception of the meter-reading request packet signal obtains, for example, the accumulated gas amount information at that time from the gas meter 14, and uses the wide area communication adapter 18-1, the mobile phone network 22 as the accumulated amount response packet signal. And it transmits toward the gas management server 26 via the internet 24. The gas meter processing unit 34 of the gas management server 28 that has detected the effective reception of the integrated amount response packet signal calculates the gas usage amount and stores it in the database 36, and the gas fee based on the gas usage amount in the database 36 on a predetermined closing date. Is calculated, and the debit processing from the user bank account is performed.

  On the other hand, the cooperation process using the gas monitoring system when the alarm system detects a fire and gives an alarm is as follows.

Here, there are two communication methods shown in FIG. 2 for alarm system cooperation of the houses 12-1 and 12-2 using the network of the gas management system according to the present invention.
(1) Wide area communication adapter direct communication method (2) Wide area communication adapter communication method via server

  FIG. 2 (A) is an outline of the direct communication method between the wide area communication adapters. For example, when a fire is detected and alarmed by the home alarm device 10-11 of the house 12-1, or from another home alarm device 10-12. When a fire-linked signal reception by the first wireless communication protocol is detected and an alarm is generated, a fire-linked packet signal according to the bus communication protocol is generated, and a home communication adapter 16-12 for linkage connected by a bus signal line is used. Send. If the home communication adapter 16-12 receives this and is valid, the fire cooperation according to the second wireless communication protocol in which the address of the home communication adapter 16-22 installed in the home 12-2 as the cooperation destination is the destination ID An interlocking packet signal is generated and transmitted to the home communication adapter 16-11.

  The home communication adapter 16-11 receives this and, when it is valid, transmits a fire cooperation interlocking packet signal according to the bus communication protocol to the wide area communication adapter 18-1. The wide-area communication adapter 18-1 that has received it effectively converts it into a fire cooperation interlocking packet signal in accordance with the communication protocol of the mobile phone network 22 as the third communication protocol, and the mobile phone base station 20-1, The data is transmitted to the wide area communication adapter 18-2 of the house 12-2 via the wide area communication network 21 composed of 20-2 and the mobile phone network 22.

  Here, the wide area communication network 21 includes the mobile phone base stations 20-1 and 20-2, the mobile phone network 22, the access point 25, the public wireless LAN communication network 26 and the Internet 24 shown in FIG.

  The wide-area communication adapter 18-2 that has received it effectively converts it into a fire cooperation interlocking packet signal according to the bus communication protocol, transmits it to the home communication adapter 16-21, and converts it into a fire cooperation interlocking packet signal according to the second wireless communication protocol. The data is converted and transmitted to the in-home communication adapter 12-22 for cooperation.

  When the home communication adapter 16-22 of the house 12-2 detects the effective reception of the fire cooperation interlocking packet signal, the home communication adapter 16-22 transmits a corresponding fire cooperation interlocking signal to the residential alarm 10-21, and fires in other houses 12-1 The other unit abnormal (fire) alarm indicating the occurrence is output. In addition, when the home alarm device 10-21 detects the effective reception of the fire cooperation interlocking signal according to the bus communication protocol from the home communication adapter 16-22, it converts it into the fire cooperation interlocking signal according to the first wireless communication protocol. Then, the alarm is transmitted to the home alarm device 10-22 of the house 12-2 in the alarm system to which the self belongs, and the other house fire alarm indicating the fire occurrence in the other house 12-1 is output.

  In order to realize such another dwelling unit fire alarm, each interlocking signal and the interlocking interlocking signal are assigned a group code of the transmitting side alarm system provided in the house 12-1, and each residential alarm 10 identifies this. In addition to this, by adding the ID of the interlocking former house alarm 10-11 and performing the same recognition process, the fire alarm content indicating the fire occurrence of other dwelling units identifies the house 12-1. It can be set as the content which specifies not only to the thing but having detected by the residence police device 10-11.

  Further, after the fire is detected by the home police 10-11 and the fire-linked packet signal is transmitted from the home communication adapter 16-12 to the home communication adapter 12-22 of the dwelling unit 12-2, the home police 10-11 When an alarm stop operation is detected by a fire recovery or alarm stop switch, the home communication adapter of the dwelling unit 12-2 sends the fire recovery interlock packet signal or the alarm stop interlock packet signal from the home communication adapter 16-12 in the same procedure as when a fire is detected. It sends to 12-22 address and stops the other dwelling unit fire alarm currently output from dwelling device 10-21, 10-22.

  FIG. 2 (B) is an outline of the communication method between the wide-area communication adapters via the server. For example, when a fire is detected by the home alarm 10-11 of the house 12-1, the address of the server 30 is set by the home communication adapter 16-12. A fire cooperation interlocking packet signal designated as the destination address is generated, and the home communication adapter 16-11. A fire cooperation interlocking packet signal is transmitted to the abnormality monitoring server 30 of the wide area communication network 21 via the wide area communication adapter 18-1 and the wide area communication network 21.

  The abnormality monitoring server 30 that has effectively received the fire cooperation interlocking packet signal searches the database 40 by the function of the cooperation control unit 38 and acquires the address of the home communication adapter 16-22 for cooperation of the house 12-2. A fire cooperation continuous packet signal is generated and transmitted to the home alarm device 10-21 via the wide area communication adapter 18-2 and the home communication adapters 16-21 and 16-22 of the house 12-2. 21 outputs a fire alarm for other dwelling units indicating that a fire has occurred in another house 12-1.

  In addition, when the home alarm device 10-21 detects the effective reception of the fire cooperation interlocking signal from the home communication adapter 16-22, it converts it into a fire cooperation interlocking signal according to the first wireless communication protocol, and the alarm to which it belongs. It transmits to the dwelling device 10-22 of the house 12-2 which becomes the system, and outputs the other dwelling unit fire alarm indicating the fire occurrence in the other house 12-1.

  In addition, when a fire is detected by the home alarm 10-11 and a fire-linked packet signal is transmitted from the in-home communication adapter 16-12 to the abnormal monitoring server 30, a fire recovery or an alarm stop operation by the alarm stop switch is detected. Sends a fire recovery interlocking packet signal or an alarm stop interlocking packet signal from the home communication adapter 16-12 to the abnormality monitoring server 30 in the same procedure as when a fire is detected, and the abnormality monitoring server 30 processes the home communication of the house 12-1. When the fire recovery interlocking packet signal or the alarm stop interlocking packet signal as the destination of the adapter 16-22 is transmitted and received by the home communication adapter 16-22, it is output from the residential alarm devices 10-21 and 10-22. Stop the other unit fire alarm.

  The merit of this inter-server wide-area communication adapter communication method is that the destination address can be freely set in the abnormality monitoring server 30, so that, for example, the fire cooperation interlocking signal is not limited to the home communication adapter 16-12 for cooperation of the house 12-2. , It can also be transmitted to the home communication adapter 16-32 of another house 12-3 to output a fire alarm for another dwelling unit from the dwelling device 10-31, enabling 1-to-n communication, and an alarm for 3 dwelling units or more System can be linked.

  In the communication system between wide area communication adapters shown in FIG. 2B, the cooperation control unit 38 provided in the abnormality monitoring server 30 can be linked to the mobile phone 32 serving as a user terminal.

  When the abnormal monitoring server 30 detects the effective reception of the fire cooperation interlocking packet signal, the function of the cooperation control unit 38 provided as an application processes the contents of the data part of the fire cooperation interlocking packet signal that is effectively received, and the processing result is displayed. The data is transmitted to the user's mobile phone 32 via the Internet 24, the mobile phone network 22, and the mobile phone base station 20-1. In response to this, the mobile phone 32 outputs a fire alarm. The output of the fire alarm in the mobile phone 32 can be performed in an appropriate form such as a display screen output or a sound output from a speaker.

  In addition, when a fire is detected by the home alarm 10-11 and a fire-linked packet signal is transmitted from the in-home communication adapter 16-12 to the abnormal monitoring server 30, a fire recovery or an alarm stop operation by the alarm stop switch is detected. Sends a fire recovery interlocking packet signal or an alarm stop interlocking packet signal from the home communication adapter 16-12 to the abnormality monitoring server 30 in the same procedure as when a fire is detected, and after processing by the cooperation control unit 38, an alarm corresponding to the processing result A stop signal is transmitted to the mobile phone 32, and an alarm stop or fire recovery is displayed on the alarm screen of the mobile phone 32 to release the fire alarm.

  The fire alarm canceling operation by the mobile phone 32 can be an appropriate operation such as outputting a canceling effect like the fire alarm output or simply stopping the fire alarm output.

  When the home alarm device 10-11 detects a fire signal transmitted from another home alarm device, a fire recovery, or an interlocked signal effective reception indicating an alarm stop operation, the abnormal monitoring server 30 is connected from the home communication adapter 16-12. In addition to transmitting the cooperation interlocking packet signal to the destination, if necessary, the corresponding interlocking signal is relayed and transmitted to another resident alarm device 10-12 belonging to its own group.

  When the cooperation control unit 38 of the abnormality monitoring server 30 detects the effective reception of the fire cooperation interlocking packet signal, it sets the address of the home communication adapter 16-12 in the destination ID of the header part, and the gas cutoff control information in the data part. A gas cutoff control linkage interlocking packet signal (shutoff control linkage linkage signal) in which (gas cutoff control command) is set is generated and transmitted to the home communication adapter 16-11, and the gas cutoff control linkage linkage is performed by the home communication adapter 16-11. When the effective reception of the packet signal is detected, the gas supply control packet signal may be transmitted to the gas meter 14 and the gas supply may be stopped by the cutoff operation of the cutoff device built in the gas meter 14.

  The gas supply cut-off by the transmission of the gas cutoff control cooperation interlocking packet signal is not performed from the abnormality monitoring server 30, but a fire cooperation interlocking packet signal is transmitted from the abnormality monitoring server 30 to the gas management server 28 to output a fire alarm. As a process of the gas management server 28 based on this fire alarm, a gas cutoff control cooperation interlocking packet signal may be transmitted to cut off the gas supply.

  Here, the first wireless communication protocol, the second wireless communication protocol, and the third wireless communication protocol in the present embodiment correspond to the first communication protocol, the second communication protocol, and the third communication protocol in the claims.

  Further, when the communication paths according to the respective wireless communication protocols in FIG. 1 are arranged, for example, between the mortgages 10-11 and 10-12 installed in the house 12-1, the resident police 10- installed in the house 12-2. The first wireless communication protocol path 11a is between 21 and 10-22, and the home communication adapters 16-11 and 16-21 connected to the gas meters 14 of each house are connected to the residential alarm devices 10-11 and 10-21, respectively. Each route between the home communication adapters 16-12 and 16-22 becomes the second wireless communication protocol route 11b, and between the wide area communication adapter 18-1 and the mobile phone base station 20-1, for example, 18-2. For example, the third wireless communication protocol path 11c is between the mobile phone base station 20-2 and the mobile phone base station 20-2.

  In addition, the 1st wireless communication protocol path | route 11a between dwelling devices 10-11 and 10-12 and dwelling devices 10-21 and 10-22 is included in the same group including other dwelling devices other than illustration. Thus, the first wireless communication protocol route is directly and relayed to each other. Further, another third wireless communication protocol path is formed between the wide area communication adapters 18-1 and 18-2 and the access point 25 of the public wireless LAN communication network 26, for example.

  FIG. 3 is an explanatory view showing an example of a fire alarm screen displayed on the mobile phone by the communication method between the wide area communication adapters via the server in FIG. In FIG. 3, when a fire alarm signal is effectively received from the abnormality monitoring server 30, the mobile phone 32 displays an alarm screen 700 and outputs a fire alarm sound.

  For example, on the alarm screen 700, if the name of the house 12-1 is "House A" and the name of the house 12-2 is "House B", for example, "Please confirm that the fire alarm in House A has been activated" An alarm message 702 is displayed. Of course, it can also be set as the content which identifies even the fire alarm which detected the fire.

  Below the alarm message 702 on the alarm screen 700, operation buttons include a confirmation button 704, a house A automatic dial button 706, a house B automatic dial button 708, 119 automatic dial buttons 710 and 710 automatic dial buttons 712, and an alarm stop button 714. Are displayed, and each button is a transparent touch panel, so that necessary operations can be performed.

  For example, when the alarm stop button 704 is operated, a confirmation signal is transmitted to the abnormality monitoring server 30 via the mobile phone ground station 20-1 and the mobile phone network 22, and it is possible to recognize that the user has been notified of the fire alarm. . When the house A automatic dial button 706 or the house B automatic dial button 708 is operated, a call connection with a fixed telephone installed in the house 12-1 or 12-2 is made possible. Further, when the 119 automatic dial buttons 708 and 110 automatic dial buttons 710 are operated, a call connection with the fire engine or police agency is made possible as necessary.

  In addition, when the alarm stop button 714 is operated, an alarm stop cooperation interlocking packet signal is transmitted to, for example, the abnormality monitoring server 30, and the abnormality monitoring server 30 that has effectively received this is installed in the houses 12-1 and 12-2. The alarm stop cooperation interlocking packet signal is transmitted to the home communication adapters 16-12 and 16-22 for cooperation, and the fire alarm output from the residential alarm devices 10-11 to 10-22 is stopped.

  Thus, the fire alarm output by the mobile phone 32 is realized by the function of the cooperation control unit 38 shown in the abnormality monitoring server 30 of FIG. The cooperation control unit 38 functions effectively based on the subscriber's service application, and is used as the information necessary for the cooperation control in the database 40. The mortgages 10-11 to 10-10 installed in the houses 12-1 and 12-2. Information indicating an installation location is registered in advance corresponding to an identification code (ID) of −22, for example, a serial number.

  When the abnormal monitoring server 30 receives the fire cooperation interlocking packet signal effectively, the abnormality monitoring server 30 acquires the information of the installation location by referring to the database 40 by the house alarm identification code (ID), and identifies the house as shown in FIG. It is possible to display an alarm indicating the operation of the house alarm.

  Of course, any part or all of the functional configuration of the database 40 and the cooperation control unit 38 provided in the abnormality monitoring server 38 as described above may be provided on the mobile phone 32 side. In addition, when the database 40 is provided on the abnormality monitoring server 30 side, registration of the above-mentioned resident alarm identification code and the like is performed by the user of the abnormality monitoring server 30 via the Internet 24 from the mobile phone 32 or another personal computer. Etc. may be performed by accessing such as.

  As described above, in cooperation with the user terminal, when a fire is detected and alarmed by the alarm system of the houses 12-1 and 12-2, a fire cooperation interlocking packet signal is transmitted to the abnormality monitoring server 30 on the Internet 24. By outputting a fire warning that identifies the dwelling unit from the user's mobile phone 32 through the processing of the abnormality monitoring server 38, even if the user is away from home, the alarm system is linked in the absence of the user. Knowing the fire detected by either one, you can take prompt and appropriate action.

[Composition of house alarm]
FIGS. 4A and 4B are explanatory views showing the appearance of a wireless interlocking smoke-type residence guard used in the present invention. FIG. 4A shows a front view and FIG. 4B shows a side view. The side provided with the attachment hook 15 is the upper side.

  In FIG. 4, the housing of the residential alarm 10 according to the present embodiment includes a cover 12 and a main body 14. A protrusion is provided at the center of the cover 12, a plurality of smoke inlets are opened around the protrusion, and a smoke detector 16 is disposed in the inside thereof, so that smoke accompanying a fire flows into the smoke detector 16. When the predetermined concentration is reached, a fire is detected by an alarm control unit described later. As the smoke detector 16, for example, a known scattered light smoke detector mechanism can be applied.

  An acoustic hole 18 is provided on the lower left side of the cover 12, and a buzzer and a speaker are incorporated behind this so that an alarm sound and a voice message can be output. An alarm stop switch 20 is provided below the cover 12.

  The alarm stop switch 20 is configured such that when a switch cover formed of a translucent member is pressed, a push switch (not shown) is pressed. An LED 22 for displaying an alarm or the like is disposed near the push switch inside the switch cover.

  The alarm stop switch 20 also functions as an inspection switch that instructs the self-inspection of the function of the home alarm 10 from the outside. For example, when the alarm stop switch 20 is operated during the fire alarm output, the fire alarm is stopped, and when the alarm stop switch 20 is operated in a normal state, a self-inspection is performed for a predetermined function, and the result is obtained by the LED 22 or a speaker. Is notified. Here, the normal state refers to a state where at least a fire alarm is being output or a failure alarm is not being output.

  Further, a mounting hook 15 having an insertion hole in the substantially central portion thereof is provided at the upper part on the back side of the main body 14, and a screw or the like is screwed into the wall of the room to be installed and hooked through the insertion hole of the mounting hook 15. The residential alarm 10 can be fixedly installed on the wall surface in a so-called wall-hanging manner.

  FIG. 5 is a block diagram showing the configuration of the main parts of a residential alarm device and a home communication adapter for cooperation used in the present invention. The following description will be made by taking the communication method between the wide area communication adapters via the server in FIG. 2B as an example.

  This is only an example, and the separation and integration of each function can be performed arbitrarily. Each part or all of each function may be executed by software (program) or may be executed by hardware.

  Moreover, in FIG. 5, although it has shown about the residence guard 10-11 installed in the house 12-1, it becomes the same structure also about other residence guards 10-12 to 10-22. The residential alarm devices 10-11 and 10-21 for connecting the in-home communication adapters 16-12 and 16-22 for cooperation described so far include an interface circuit unit for this purpose. 10-12 and 10-22 do not necessarily have to be provided with an interface circuit section.

  First, the house alarm 10-11 will be described. The home guard 10-11 includes a processor 100 known as a one-chip CPU, and a first wireless communication unit 102 that transmits and receives the first wireless communication protocol connected to the antenna 104 is connected to the processor 100. An interface circuit unit 106, a sensor unit 108, a notification unit 110, an operation unit 112, and a memory 114 that transmit and receive signals to and from the home communication adapter 16-12 according to a bus communication protocol are provided. Supply.

  The first wireless communication unit 102 is provided with a first transmission circuit 118 and a first reception circuit 120 to which an antenna 104 is connected. The first wireless communication unit 102 communicates with other residential alarm devices 10-12 via the antenna 104 in accordance with a first wireless communication protocol that complies with the standard of a specific low power wireless station in the 400 MHz band, for example. Send and receive various interlocking signals such as recovery, alarm stop, and failure.

  In the transmission of the interlocking signal by the first wireless communication protocol in the first transmission circuit 118 of the first wireless communication unit 102, the operation of transmitting the interlocking signal for a predetermined time T1, for example, T1 = 3 seconds, is performed for the predetermined time T2, for example, T2. For example, four times with a pause of 2 seconds. This T1 = 3-second transmission and T = 2-second pause comply with the standard of a specific low-power radio station. Further, in the transmission operation of T1 = 3 seconds, for example, 2.8 seconds from the beginning of the transmission operation is a dummy signal transmission, and the interlocking signal is repeatedly transmitted in the remaining 0.2 seconds.

  In addition, the reception by the first wireless communication protocol in the first receiving circuit 120 of the first wireless communication unit 102 is intermittently received and decoded by the interlocking signal from the other residential alarm device 10-12. In the intermittent reception, the reception operation is repeated for a predetermined period T3, for example, every T3 = 7 seconds, for a receivable time T4, for example, T4 = 100 milliseconds, and during the receivable time T4, the transmission dummy signal is carrier sensed. When the signal is detected, the reception is switched to continuous reception for a predetermined time, and the interlocking signal following the dummy signal is received and decoded.

  The received signal is decoded by an alarm control unit 128 provided in the processor 100. Hereinafter, the process up to this decoding may be referred to as reception. In particular, when the signal is determined to be valid as a result of decoding, it is called effective reception. “Detecting reception” in the claims means “effective reception” or “detecting effective reception”.

  Further, in the first wireless communication protocol, when the resident guard 10-11 itself detects a fire or an event other than a fire and transmits an interlock signal, the interlock signal is transmitted from another resident alarm 10-12 that has received this effectively. It is monitored whether or not an acknowledgment signal (hereinafter referred to as “ACK signal”) indicating that the signal has been normally validly received is validly received.

  When the other resident alarm is detected that the ACK signal is not effectively received, the resident alarm 10-11 transmits the relay request request interlock signal to the other resident alarm whose ACK signal is effectively received, A relay signal with a relay request is relay-transmitted from a home alarm device that has effectively received a relay signal with a relay request to a home alarm device that has not yet responded to an AKC signal. An ACK signal not responding to an AKC signal that has been relayed and received effectively from the interlock signal with the relay request returns an ACK signal to the interlock signal with the relay request, and this ACK signal is relayed to another resident alarm (reply relay) ) And received by the interlocking home resident guard 10-11. If there is a residence guard that does not effectively receive the ACK signal, it is determined that there is a communication failure or the like, and a predetermined notification process or interlocking process, a cooperative process described later, or the like is performed.

  The above-described relay function is useful when three or more house alarms are installed in one interlocking group, for example, the house 12-1. In the example of FIG. 1, since only two units of the residence guard 10-11 and the residence guard 10-12 are installed in the house 12-1, the residence guard 10-11 responds to the interlocking signal transmitted by itself. When the ACK signal (reply) is not received effectively from the resident alarm device 10-12, it is determined as a communication failure or the like, and a predetermined notification process or a cooperation process described later is performed.

  A signal transmitted and received by the first wireless communication protocol is configured in a format including a serial number, a transmission source ID, a group ID, and an event code. A serial number is a code | symbol produced | generated independently for every residence warning device, and is a serial number which shows the production | generation order or transmission order of an interlocking signal. Based on this, management such as prohibition of re-relay can be performed. The transmission source ID is, for example, a serial number of the residential police device that identifies each residential police device, and the group ID is the residential police device 10-11, 10- installed in the houses 12-1, 12-2 as shown in FIG. 12 or the code | symbol for comprising the interlocking | linkage group which mutually interlock | cooperates with each of the housing alarm devices 10-21 and 10-22.

The event code is a code representing the content of an event such as a fire. In the present embodiment, a 4-bit code is used. For example, 0001 = fire 0010 = ACK
0011 = Alarm stop 0100 = Recovery 0101 = Sensor failure 0110 = Low battery failure 0111 = Recovery (fire recovery, failure recovery)
It is said. That is, the resident alarm of this embodiment transmits an interlocking signal including an event code in response to abnormality detection (fire detection), abnormality recovery (fire recovery), alarm stop, failure detection or failure recovery as its own event. In addition, a process corresponding to the reception of the interlocking signal from the other house alarm is performed.

  Note that the above-described code indicating “relay request is present” is omitted here, but it can be added to the event code by increasing the number of bits. In addition, both the ID indicating the transmission source (linkage source) residence alarm device and the ID of the residence alarm device relaying are added to the linkage signal to be relayed. Further, an ID for designating a transmission destination may be added.

  Further, although the above-described code indicating “relay request is present” is omitted here, for example, it can be added to the event code by assigning it to “1111”, for example. Further, for example, “0000” may be assigned for periodic communication confirmation. Of course, more event codes can be assigned by increasing the number of bits.

  A home communication adapter 16-12 for cooperation is connected to the interface circuit unit 106 via the bus signal line 60. The interface circuit unit 106 is provided with a transmission bus circuit 122 and a reception bus circuit 124, and transmits and receives various signals associated with fire monitoring according to a predetermined bus communication protocol. A predetermined port number is assigned to the interface circuit unit 106.

  The sensor unit 108 is provided with a smoke detector 16 that detects smoke based on the scattered light smoke detection principle and outputs a detection signal corresponding to the smoke density.

  The notification unit 110 is provided with a speaker 126 that is an acoustic output device that outputs an alarm sound and the like, and an LED 52 that performs alarm display and the like along with respective drive circuits (not shown). Under the control of the alarm control unit 128, the speaker 126 outputs a voice message, an alarm sound, or the like based on various data stored in the memory 114 or the like by the resident alarm 10-11. The LED 52 notifies the display of abnormalities and other events such as a fire by blinking, blinking, or lighting.

  The operation unit 112 is provided with an alarm stop switch 50. The alarm stop switch 50 also functions as an inspection switch as described above.

  The memory 114 stores a serial number, an identification code, a group code, and the like used for generating the interlocking signal.

  The battery power supply 116 uses, for example, a lithium battery or an alkaline battery having a predetermined number of cells, and supplies power to necessary parts. As the battery capacity, for example, a lifetime of 10 years is guaranteed by reducing the power consumption of the entire circuit unit in the residence guard 10-11.

  The processor 100 is provided with functions of an alarm control unit 128 and a cooperation processing unit 130 as functions realized by executing the program.

  The alarm control unit 128 detects whether there is a fire based on a detection signal from the smoke detection unit 46 provided in the sensor unit 108, whether there is an alarm stop instruction input by the operation unit 112, whether there is an inspection instruction input, An event such as the presence or absence of a fire restoration, the presence or absence of a sensor failure or a low-battery failure is detected in which the detection signal from the smoke unit 46 is reduced to cancel the fire detection state. Further, the alarm control unit 128 detects the presence / absence of the interlocking signal effective reception obtained as a result of decoding the interlocking signal from the other residential alarm device 10-12 through the first receiving circuit 120 and the interlocking content.

  When the alarm control unit 128 detects the presence of a fire based on the smoke detection signal of the smoke detection unit 46 provided in the sensor unit 108, the alarm control unit 128 notifies the notification unit 110 of a fire alarm sound indicating the interlock source, for example, “Woo Woo Fire” It is controlled to repeatedly output the voice message “Please confirm that it is a fire”, and the LED 52 is turned on to perform a control to display a fire alarm indicating the interlocking source, and the first wireless communication unit 102 Control is performed to cause the transmission circuit 118 to transmit a fire-linked signal according to the first wireless communication protocol from the antenna 104 to the other residential alarm device 10-12.

  In addition, the alarm control unit 128 activates the fire-linked signal according to the first wireless communication protocol from any of the other home alarm devices 10-12 via the antenna 104 and the first receiving circuit 120 of the first wireless communication unit 102. When it is detected that the alarm has been received, an alarm message indicating the link destination is output from the speaker 126 of the notification unit 110 as an alarm message indicating the link destination, for example, “Please confirm that another fire alarm has been activated”. Are repeatedly output and the LED 52 is blinked, for example, to display an alarm indicating the interlocking destination. Furthermore, the first transmission circuit 118 is controlled to transmit an ACK signal as a response signal (reply) associated with the effective reception of the fire interlock signal from the interlock source.

  When the alarm control unit 128 detects the operation of its own alarm stop switch 50 during the output of the fire alarm sound indicating the interlock source, the alarm control unit 128 controls the alarm unit 110 to output the alarm sound from the speaker 126 and the alarm display of the LED 52. The fire alarm operation by the output is stopped, and an alarm stop interlocking signal according to the first wireless communication protocol is transmitted from the antenna 104 to the other residential alarm device 10-12 to the first transmission circuit 118 of the first wireless communication unit 102. Control to send to.

  When the alarm control unit 128 detects the effective reception of the alarm stop interlocking signal from the other residential alarm device 10-12 while the fire alarm sound indicating the interlocking source is being output, The unit 128 enables at least one of the fire alarm sound and the fire alarm display to identify the interlock source without performing stop control until at least a predetermined period has elapsed.

  Further, when the alarm control unit 128 detects the operation of the alarm stop switch 50 or the effective reception of the alarm stop interlocking signal from the other residential alarm device 10-12 during the output of the alarm sound indicating the interlocking destination, the alarm control unit 128 causes the notifying unit 110 to operate. Control is performed to stop the output of the alarm sound by the voice message from the speaker 126 and the fire alarm by the alarm display of the LED 52.

  Further, the alarm control unit 128 returns an ACK signal accompanying the reception of the alarm stop interlocking signal in the same manner as when the fire interlocking signal is received. In addition, since it is the same also in each case mentioned later, description is abbreviate | omitted about the reply of the ACK signal accompanying communication between residence police. It should be noted that the ACK signal transmission / reception processing can be performed in the same way in the communication between the resident alarm and the gateway device, but the description thereof is also omitted. Although communication retries can be performed as appropriate, the description is omitted in this specification.

  In addition, the alarm control unit 128 is provided with a low battery failure monitoring function in which the power supply voltage supplied from the battery power supply 116 is less than a predetermined level in cooperation with a voltage monitoring circuit (not shown). The test is automatically executed periodically in the background, and the result is updated and recorded in the memory 114 each time.

  Specifically, the low battery fault monitoring is performed by reading a power supply voltage supplied from the battery power supply 118 at a predetermined measurement time interval (cycle), for example, at an interval of 4 hours, via a voltage monitoring circuit (not shown), and a predetermined threshold voltage. A built-in test is performed, and when the threshold voltage is less than the threshold voltage, a low battery failure is preliminarily determined and stored in the memory 114, and when the low battery failure preliminary determination continues for a predetermined number of times, the low battery failure is preliminarily determined. A battery failure is determined (determined) and detected, a low battery failure flag is set, and the memory 114 is updated and stored.

  In addition, the alarm control unit 128 is provided with a sensor failure monitoring function for monitoring failures (including part deterioration and failure) of the sensor unit 108, and is automatically executed periodically in the background as a built-in test. Specifically, the sensor failure monitoring reads a smoke detection signal output from the smoke detector 46 of the sensor unit 108 at a predetermined measurement time interval (period), for example, 1 second, and holds the smoke detection signal in the memory 114. The average value of the detected data for the last 10 minutes held in the memory 114 is obtained every time interval, for example, every 10 minutes, and the output is stopped when the average value falls below a predetermined reference level (referred to as the zero point level). It is determined that the sensor unit 108 is faulty as being in a state, and the sensor fault flag is set, and the memory 114 is updated and stored.

  When the alarm control unit 128 detects an inspection instruction operation (inspection instruction input) by operating the alarm stop switch 50 that functions as an inspection switch in a normal state, the low battery failure flag or the sensor failure flag is set and stored in the memory 114. If it is determined that the low battery failure alarm or sensor failure alarm is output from the notification unit 110, the low battery failure alarm or the sensor failure alarm is output from the notification unit 110 via the first transmission circuit 118 of the first wireless communication unit 102. A battery fault interlocking signal or a sensor fault interlocking signal is transmitted to the other residential alarm devices 10-12 to output a low battery fault alarm or a sensor fault alarm indicating the fault interlocking destination.

  Needless to say, a low battery failure or a sensor failure may be notified and an interlocking signal transmitted when the failure is detected by a built-in test regardless of the inspection instruction operation.

  In addition to a low battery failure and a sensor failure, various types of circuit failures and failures such as aging may be detected and the same processing may be performed.

  When the alarm control unit 128 detects a fire, the cooperation processing unit 130, or from any of the other home alarm devices 10-12 through the antenna 104 and the first receiving circuit 120 of the first wireless communication unit 102, 1 When the effective reception of the fire-linked signal according to the wireless communication protocol is detected, a fire-linked packet signal according to the bus communication protocol is generated in response to an instruction from the alarm control unit 128, and the transmission bus of the interface circuit unit 106 The signal is transmitted from the circuit 122 via the bus signal line 60 to the in-home communication adapter 16-12 for cooperation.
