Description

  The present invention relates to an alarm linkage system in which an alarm system installed in each of a plurality of dwelling units is linked via a CATV transmission line.

  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 the need for receiving equipment, etc., which is provided in so-called automatic fire alarm equipment, installation is simple and inexpensive, and installation in ordinary houses It has become widespread with the obligation.

  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. "

JP 2010-020663 A JP 2009-259125 A JP 11-252522 A Japanese Patent Laid-Open No. 10-228596 Japanese Utility Model Publication No. 63-192895 JP 2011-197994 A

  By the way, in such a fire alarm system using a conventional interlocked house alarm, for example, one alarm system is usually used to monitor one dwelling unit, and each place requiring fire monitoring in this dwelling unit is used. When a fire is detected by any of these home guards, other home guards are linked to this, and as a result, It is based on alarming.

  However, as a form of use of the alarm system using the interlocking type house alarm device, a case in which cooperation is required between alarm systems installed in different dwelling units is assumed. For example, if a parent household and a child household live in different places (units) and an alarm system using an interlocking alarm is installed in each unit, the two alarm systems are linked to each other. If an alarm can be made, it is possible to enhance the function of the alarm system, such as expanding the scope of alarm linkage, and to increase the sense of security of the user. However, there is no effective mechanism that can be easily handled.

  On the other hand, the CATV system provides a TV program viewing service by sending a TV signal to a subscriber's house via a tree-structured CATV transmission line with the head end as a vertex. The network is connected to an external network such as the Internet using the same transmission path, and the network can be accessed by a personal computer at the subscriber's house.

  The present invention is an alarm linkage system capable of improving reliability and a sense of security by extending and strengthening functions by, for example, a mechanism for mutually linking alarm systems installed in a plurality of dwelling units via a CATV transmission line. The purpose is to provide.

When multiple alarm systems equipped with multiple alarm devices that interlock and alarm by sending and receiving abnormal interlocking signals are connected via a communication network and abnormalities are detected by any alarm system, abnormal alarm signals from the alarm system Is an alarm linkage system that sends alarms in cooperation with other alarm systems,
The alarm device of the cooperation source alarm system is
When an alarm stop interlocking signal is received while an abnormality is detected and the interlocking source alarm sound and alarm display are being output, the output of at least one of the alarm sound or the alarm display is maintained until at least a predetermined time has passed,
If an alarm stop interlock signal is received while receiving an abnormal interlock signal and outputting the alarm sound and alarm display of the interlock destination, stop the output of the alarm sound and alarm display,
The alarm device of the linked alarm system is
While receiving the abnormal cooperation signal and outputting the alarm sound and alarm display of the cooperation destination, either the alarm stop cooperation signal from the cooperation source alarm system or the alarm stop cooperation signal from other alarm devices in your own alarm system The alarm cooperation system which stops the output of the alarm sound and the alarm display when receiving.

  According to the present invention, for example, when a predetermined abnormality such as a fire is detected by an alarm device of an alarm system provided in any of a plurality of dwelling units, the alarm device that detects the abnormality and the same alarm system (for example, in the same dwelling unit) A fire alarm is output from another alarm device (installed), and a fire cooperation interlocking signal is transmitted as an upstream signal from the CATV adapter to the CATV transmission line. An upstream signal is converted into a downstream signal, and a fire linkage signal is transmitted to the alarm device of another dwelling unit via another CATV adapter, and a fire alarm is also output by the alarm device constituting the alarm system of the other dwelling unit. For example, using CATV transmission lines to link alarm monitoring by an alarm system installed separately in units separated from each other , You can extend the overall interlocking range simple and flexible, and can increase the sense of security to expand the scope of the corresponding respective user.

  In addition, for example, for a fire recovery or alarm stop of a resident alarm, the inter-unit cooperation link signal is transmitted to the alarm system installed in another unit via the CATV transmission line, and the unit is linked. Can be notified.

  In addition, for example, when a low battery failure or sensor failure of a resident alarm operating with a built-in battery (battery) power source is detected, the linkage interlocking signal is transmitted via the CATV transmission line, and the interlocking interlocking is performed. It is possible to notify from the alarm device.

  Furthermore, in the CATV system, by utilizing the CATV transmission path for the cooperation of the alarm system, a new service called alarm cooperation between a plurality of dwelling units can be provided, and by increasing the utility value of the CATV system, It is possible to improve the subscriber service of the CATV system.

  Further, these can be realized only by providing at least one CATV adapter for each alarm system after providing an up-down converter in the CATV system.

The flowchart which illustrated the outline of the processing by a resident alarm following FIG.

  FIG. 1 is an explanatory diagram showing a schematic configuration example of an alarm cooperation system when alarm systems installed in two houses (two dwelling units) are linked according to the present invention. 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 also be used between business establishments and between multiple buildings in the same facility.

  In FIG. 1, the house 24-1 is, for example, a house of a parent household, the house 24-2 is a house of a child household, and they are different places, for example, separated by a distance exceeding the mutual wireless communication range. It is built in. A wireless interlocking residence alarm (residential fire alarm) 10- that detects and interlocks with a fire in predetermined alert areas (monitoring areas) such as the kitchen, living room, main bedroom, and staircase of the house 24-1. 11 and 10-12 are installed, and the interlocking type alarm system is constructed. In addition, a wireless interlocked house alarm (residential fire alarm) that also detects fires and interlocks alarms in surveillance areas such as kitchens, living rooms, children's rooms, main bedrooms, and staircases of the house 24-2. ) 10-21 and 10-22 are installed, and an interlocking type alarm system is also constructed here.

  For convenience of explanation, the housings 24-1 and 24-2 are illustrated with two housing alarms installed, but the number of alarming devices (number of interlocking units) constituting each alarming 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 may be referred to as the house alarm device 10 when collectively referred to without being distinguished from each other.

  In addition, here, a case where alarm devices are linked in the same alarm system is called “linkage”, and a case where different alarm systems are linked is called “linkage”. In addition, as a result of cooperation, the fact that an alarm device is linked in the linked alarm system may be referred to as “linked linkage”.

  In addition, a signal transmitted and received between alarm devices in the same alarm system is referred to as a “linked signal”, and a signal transmitted and received between alarm devices of different alarm 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 fault interlock signal. The latter interlock signal corresponds to the fire interlock signal, the fire recovery interlock signal, and the alarm. There are stop cooperation interlocking signals and fault cooperation interlocking signals.

  In addition, CATV adapters 100-1 and 100-2 are installed in the homes 24-1 and 24-2 in order to link alarm systems constructed for each through the transmission line of the CATV system 200. . Hereinafter, the CATV adapters 100-1 and 100-2 may be collectively referred to as CATV adapters 100 when not distinguished from each other.

  In the CATV system 200, a UHF antenna 205, a BS antenna 206, and a CS antenna 208 are connected to a head end 202, and a trunk line is distributed to a CATV transmission line 204 having a tree structure using a coaxial cable drawn from the head end 202. An amplifier (TDA) 210, a main branch amplifier (TBA) 220, and a distributor 230 are provided, and finally connected to the TV terminals 250 in the homes 24-1 and 24-2 as subscribers via the CATV protector 240. ing. The TV terminal 250 has, for example, two terminals distributed by a terminal distributor (not shown), the TV 260 is connected to one terminal, and the CATV adapter 250 is connected to the other terminal.

  In addition, the CATV transmission line 204 is provided with a branching amplifier (BA), a distribution amplifier (TA), an extension amplifier (EA), etc. as necessary, but is omitted for the sake of simplicity. . Further, in the optical CATV system, an optical coaxial transmission line (HFC transmission line) is used, an optical node is provided following the head end 202, and the optical node and subsequent parts are used as coaxial cable transmission lines.

  In such a CATV system 200, a television signal is transmitted as a downlink signal using a predetermined downlink frequency band from the head end 202 to the subscriber side via the CATV transmission line 204 to provide a television viewing service. Similarly, an uplink signal is transmitted from the subscriber side to the head end 202 via the CATV transmission line 204 using a predetermined uplink frequency band.

  The alarm linkage system of the present invention transmits and receives signals via the CATV transmission line 204 between the CATV adapters 100-1 and 100-2 provided in the homes 24-1 and 24-2 serving as subscribers' homes. Although the alarm system is linked, the upstream signal of the CATV system 200 is a signal transmitted from the subscriber terminal to the head end 202, and in this state, the signal is transmitted between the CATV adapters 100-1 and 100-2 provided as subscriber terminals. Cannot be sent or received.

  Therefore, in the present invention, the upstream / downstream converter 300 is arranged at the top of the tree structure in the CATV transmission line 204 or upstream thereof, for example, between the head end 202 and the first main line distribution amplifier 210.

  The uplink / downlink conversion apparatus 300 separates an uplink signal having a predetermined uplink frequency f1 transmitted from any one of the CATV adapters 100-1 and 100-2, converts the frequency into a downlink signal having a predetermined downlink frequency f2, and transmits the downlink signal. Signal transmission / reception between the CATV adapters 100-1 and 100-2 via the CATV transmission path 204 is enabled.

  The home alarm 10 has a function of wirelessly transmitting and receiving interlocking signals to each other within the alarm system to which it belongs, and monitors the presence or absence of a fire in the corresponding monitoring area in each place of the house. If a fire should have occurred in the house 24-1, now, 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 warning, the home alarm device 10-11 functions as an interlocking source, performs an alarm operation of the interlocking source, and fire interlocks with another housing alarm device 10-12 that is the interlocking destination. Wireless transmission of signals. 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, the home alarm device 10 confirms that the group code included in the received interlocking signal matches the group code registered in its own memory and is a signal in the alarm system to which it belongs, and the signal When the content is recognized normally, it is detected that this interlocking signal has been received effectively. 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 the alarm operation of the home alarm device 10-11 that is the link source, for example, a fire alarm sound is output by a voice message such as “Please confirm that the Woo Woo fire alarm has been activated”. On the other hand, the interlocking destination home alarm device 10-12 outputs a fire alarm sound by a voice message such as “Please confirm that another fire alarm device has been activated”.

  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 interlocked residence police 10-12, the LED blinks. As a result, the alarm display by the LED in the interlock source alarm and the interlock destination alarm can be distinguished. Here, these alarm displays are also included in the alarm operation of the interlocking source or interlocking destination.

  When the home alarm device 10 detects a fire, the home alarm device 10 transmits a fire interlocking signal in accordance with a predetermined wireless communication protocol to other home alarm devices and the CATV adapter 100 belonging to the same alarm system. Further, the home alarm device 10 receives a fire-linked signal transmitted from another home alarm device belonging to the same alarm system according to the same 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 wireless communication protocol in the home guard 10 is, for example, STD-30 known as a standard for a specific low power radio station in the 400 MHz band (radio equipment standard for a low power security system radio station). ) Or STD-T67 (standard for 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 specific low power radio station is 10 mW or less in the case of STD-30, 10 mW or less or 1 mW or less in the case of STD-T67, and the line-of-sight communication distance is about several tens to It will be about 100 meters.

  The CATV adapter 100 includes an alarm device communication function for transmitting and receiving signals in accordance with the same wireless communication protocol as the residential alarm device 10, a CATV communication function for transmitting and receiving upstream and downstream signals to and from the CATV transmission path 204, and alarm device communication. And a function for performing protocol conversion between CATV communication and CATV communication.

  For example, when a fire is detected by the residence guard 10-11 of the house 24-1, the residence guard 10-11 transmits a fire interlocking signal to the residence guard 10-12 in the alarm system to which the self belongs, thereby interlocking the alarm. (Alarm action as the link destination) is performed. This fire-linked signal is also received as a fire-linked signal by the CATV adapter 100-1. When the CATV adapter 100-1 thus receives the fire-linked signal from the home police device 10-11, the CATV adapter 100-1 generates a fire-linked signal that specifies the address of the destination CATV adapter 100-2 as the content of the received fire-linked signal. Then, it is converted (modulated) into an upstream fire cooperation interlocking signal using a predetermined upstream frequency f 1 and transmitted to the CATV transmission line 204.

  The upstream / downstream conversion apparatus 300 provided in the CATV transmission path 204 separates the upstream fire cooperation interlocking signal of the upstream frequency f1 transmitted from the CATV adapter 100-1 and converts the frequency into the downstream fire cooperation interlocking signal of the predetermined downstream frequency f2. Then send. The downlink fire cooperation interlocking signal transmitted from the ascending / descending conversion device 300 is received by the CATV adapter 100-2 of the house 24-2, and is sent to the alarm devices 10-21 and 10-22 of the alarm system provided in the house 24-2. On the other hand, a fire cooperation interlocking signal is wirelessly transmitted, and a fire alarm (other dwelling unit fire alarm) indicating the occurrence of a fire in the house 24-1 is performed from the housing alarm devices 10-21 and 10-22. Here, “other dwelling units” refers to other alarm systems (other systems). same as below.

  As a fire alarm operation of other dwelling units by this dwelling device 10-21, 10-22, for example, “Please confirm that the fire alarm of Dwelling unit A has been activated” repeatedly, a voice message specifying the house 24-1 is repeated. At the same time, the LED 22 is turned on to display a fire alarm. Here, it is possible to specify and notify which dwelling unit of dwelling unit A has detected a fire.

  In order to realize the fire alarm of the house 24-1 which is another dwelling unit in such a house 24-2, each interlocking signal and the interlocking interlocking signal are assigned the group code of the transmission side alarm system provided in the house 24-1. In addition to this, each residence guard 10 performs an identification process, and in addition to this, an ID (an identifier which will be described later as a sender identification code) of the interlocking origin residence guard 10-11 is attached and the recognition process is similarly performed. By making it, the other dwelling unit fire alarm content can specify not only the house 24-1 but also the contents that have been detected by the house alarm device 10-11. In addition, the fact that the group code of the transmission side alarm system provided in the house 24-1 corresponds to “dwelling unit A”, for example, is registered in advance in the memory of the housing alarm devices 10-21 and 10-22 constituting the house 24-2. The stored table is recognized and recognized.

  In addition to the STD-30 or STD-60 described above, the wireless communication protocol of the home guard 10 and the CATV adapter 100 is, for example, 900 MHz assigned to RFID (Radio Frequency IDentification “abbreviation of individual identification by radio waves”). A short-range wireless communication protocol for sensor networks known as Z-Wave (R) or ZigBee (R) using frequencies, ie 950-957 MHz, may be used.

  On the other hand, when a fire is detected and alarmed by the residence police 10-11 of the house 24-1, after the fire recovery or the alarm stop operation of the operation unit provided by the residence police 10-11 is detected, the residence police 10 -11 transmits a fire recovery interlock signal or an alarm stop interlock signal in the dwelling unit to the residential alarm device 10-12 and the CATV adapter 100-1.

  The CATV adapter 100-1 that has received the address specifies the address of the CATV adapter 100-2, and then sends the recovery linkage interlock signal or the alarm stop linkage interlock signal to the upstream fire recovery linkage interlock signal using the upstream frequency f1. It is converted into an upstream alarm stop cooperation interlocking signal and transmitted to the CATV transmission line 204, and the upstream and downstream conversion device 300 converts the frequency to a downstream fire recovery cooperation interlocking signal or a downstream alarm stop cooperation interlocking signal and transmits it to the CATV adapter 100-2. Then, the CATV adapter 100-2 that has received the message further converts the protocol to the residence guards 10-21 and 10-22 of the house 24-2, and transmits a fire recovery linkage signal or an alarm stop linkage linkage signal. Stop.

  In addition, when the alarm stop operation of the operation part provided in the residence warning device 10-12 is performed in the same situation, the residence warning device 10-12 that detects this stops the alarm operation of the interlocking destination (self). At the same time, an alarm stop interlocking signal is transmitted to the home alarm device 10-11, which is received by the home alarm device 10-11, and the alarm stop process of the interlocking source is performed as necessary. Further, the alarm stop interlocking signal from the resident alarm 10-12 is also received by the CATV adapter 100-1 as an alarm stop interlocking interlocking signal, and the alarm stop interlocking interlocking signal frequency-converted in the same manner as described above is also transmitted to the up / down converter. It is transmitted to the CATV adapter 100-2 via 300. Then, the CATV adapter 100-2 transmits the alarm stop cooperation interlocking signal to the dwelling devices 10-21 and 10-22, and the other dwelling unit fire alarms output from the dwelling devices 10-21 and 10-22 having received this signal. Is stopped.

  Here, when the communication paths in FIG. 1 are arranged, for example, between the residential alarm devices 10-11 and 10-12 installed in the house 24-1, a wireless communication path 11a is provided, and the residential alarm devices 10-11 and 10-12 are connected. A wireless communication path 11b is provided between each of them and the CATV adapter 100-1. This also applies to the house 24-2.

  2A and 2B are explanatory views showing the appearance of a wireless interlocking smoke-type home alarm used in the present invention. FIG. 2A shows a front view and FIG. 2B shows a side view. The side provided with the attachment hook 15 is the upper side.

  In FIG. 2, 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 in the center of the cover 12, a plurality of smoke inlets are opened on the peripheral side surface of 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 a 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.

  A plurality of acoustic holes 18 are 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 built-in push switch (not shown) is pressed in cooperation with the switch cover. 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 a wall surface or the like of a room to be installed and hooked through the insertion hole of the mounting hook 15. Thus, the residential alarm 10 can be fixedly installed on the wall surface in a so-called wall-hanging manner.

  FIG. 3 is a block diagram showing the configuration of the main part of the house alarm used in the present invention. This is an example, and the separation and integration of each function can be performed arbitrarily. In addition, any or all of each function may be executed by software (program) or may be executed by hardware. Moreover, in FIG. 3, although it has shown about the residence guard 10-11 installed in the house 24-1, in the case of this embodiment, it becomes the same structure also about other residence guards 10-12 to 10-22.

  In FIG. 3, the home alarm device 10-11 is provided with a processor 28 known as a one-chip CPU. A wireless communication unit 30 that transmits and receives signals to and from the processor 28 using a predetermined wireless communication protocol, a memory 32, A sensor unit 34, a notification unit 36, and an operation unit 38 are provided, and the battery power supply 40 supplies power to necessary units.

  The wireless communication unit 30 is provided with a transmission circuit 42 and a reception circuit 44 to which an antenna 31 is connected. The wireless communication unit 30 communicates with other residential alarms 10-12 according to a wireless communication protocol that complies with the standard of a specific low power wireless station in the 400 MHz band, for example, various types of fire, fire recovery, alarm stop, failure, etc. Send and receive interlocking signals. The wireless communication unit 30 transmits various interlocking signals such as fire, fire recovery, alarm stop, and failure to the CATV adapter 100-1, and fire, fire recovery, alarm stop, failure, etc. transmitted from the CATV adapter 100-1. The various linkage interlocking signals are received.

  The transmission of the interlocking signal in the transmission circuit 42 of the wireless communication unit 30 includes an operation of transmitting the interlocking signal for a predetermined time T1, for example, T1 = 3 seconds, with a pause of a predetermined time T2, for example, T2 = 2 seconds, for example. Repeated 4 times. 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.

  Moreover, in the receiving circuit 44 of the radio | wireless communication part 30, the interlocking | linkage signal from the other residence guard 10-12 which belongs to the same group as the residence guard 10-11 is intermittently received. 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. The same applies to the reception of various linkage interlocking signals transmitted from the CATV adapter 100-1.

  The received signal is decoded by an alarm control unit 46 provided in the processor 28. 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.

  Moreover, in the wireless communication of this embodiment, when the resident guard 10-11 itself detects a fire or an event other than a fire and transmits an interlocking signal, the resident guard 10-11 belongs to the same group as itself, It is monitored whether or not an acknowledgment signal (hereinafter referred to as “ACK signal”), which is a reply indicating that the interlocking signal has been normally received, is effectively received from the other house alarm device 10-12 received. .

  When the other resident alarm is detected that the ACK signal is not received, the resident alarm 10-11 includes a relay request interlocking signal including a code indicating a relay request to the other resident alarm that has received the ACK signal. The relay request interlocking signal is relay-transmitted from the home alarm device that has received the relay request interlocking signal to the home police device that has not yet responded to the AKC signal. The AK that has not received the relay request interlocking signal returns an ACK signal in response to the relay request interlocking signal, and this ACK signal passes through the relay of other housing alarms (reply relaying). It is received by the home guard 10-11. Accordingly, if there is a residence guard that does not receive the ACK signal, it is determined as a communication failure or the like, and a predetermined notification process, a linkage process, a linkage process described later, and the like are performed.

  The relay function described above is useful when three or more home alarm devices are installed in one interlocking group, for example, the house 24-1. 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 24-1, the residence guard 10-11 responds to the interlocking signal transmitted by itself. When an ACK signal (reply) is not received from the mortgage 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 in the wireless communication according to the present embodiment includes a serial number, a transmission source identification code, a group code, 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 identification code is, for example, the serial number of the residential police device that identifies each residential police device, and the group code is the residential police device 10-11 installed in each of the houses 24-1 and 24-2, as shown in FIG. , 10-12, or Sumisho 10-21, 10-22 is a code for constituting an interlocking group that interlocks with each other. This interlocking group also includes CATV adapters 100-1 and 100-2.

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.

Furthermore, in this embodiment, as an event code corresponding to the transmission / reception of the linkage interlocking signal between the dwelling units,
0111 = Other unit fire 1000 = Other unit alarm stop 1001 = Other unit restoration 1010 = Other unit sensor failure 1011 = Other unit low battery failure is added. It should be noted that both the transmission source identification code indicating the transmission source (linkage source) residence warning device and the transmission source identification code of the residence security device performing relay are added to the linkage signal to be relayed. Further, an identification code 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.

  The memory 32 stores a serial number used for generating the interlocking signal, its own transmission source identification code, a group code, and the like.

  As described with reference to FIG. 2, the sensor unit 34 is provided with the smoke detector 16 that detects smoke based on, for example, the scattered light type smoke detection principle and outputs a detection signal corresponding to the smoke density.

  The notification unit 36 is provided with a speaker 50 that is an acoustic output device that outputs an alarm sound and the like, and an LED 22 that performs alarm display and the like along with respective drive circuits (not shown). Under the control of the alarm control unit 46, the speaker 50 outputs a voice message, an alarm sound, or the like based on various data stored in the memory 32 or the like by the residence guard 10-11. The LED 22 notifies an abnormality or other event such as a fire by a display by blinking, blinking, or lighting.

  The operation unit 38 is provided with an alarm stop switch 20, and the alarm stop switch 20 also functions as an inspection switch as described above.

  The battery power source 40 uses, for example, a lithium battery or an alkaline battery having a predetermined number of cells, and supplies power to necessary parts. As a 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 10-1.

  The processor 28 is provided with a function of the alarm control unit 46 as a function realized by executing the program.

  The alarm control unit 46 includes a presence / absence of a fire based on a detection signal from the smoke detection unit 16 provided in the sensor unit 34, a presence / absence of an alarm stop instruction input or an inspection instruction input by the alarm stop switch 20 provided in the operation unit 38, The detection signal from the smoke detector section 16 provided in the sensor section 34 is lowered to detect the presence or absence of a fire recovery that eliminates the fire detection state, sensor failure or failure, low battery failure, or other events. Further, the alarm control unit 46 detects information on the presence / absence of effective reception of the interlocking signal and the interlocking contents obtained as a result of decoding the interlocking signal from the other residential alarm device 10-12 via the antenna 31 and the receiving circuit 50. .

  When the alarm control unit 46 detects a fire (presence) based on the smoke detection signal of the smoke detection unit 16 provided in the sensor unit 34, the alarm control unit 46 issues a fire alarm as an alarm operation indicating an interlocking source from the speaker 50 to the notification unit 36. Sound, for example, “Woo Woo is a fire. Please confirm that it is a fire” is repeatedly output, and the LED 22 is turned on to perform a fire alarm display indicating the interlocking source. 30 transmission circuits 42 are controlled to transmit a fire interlocking signal to the other residential alarm devices 10-12 and the CATV adapter 100-1.

  Further, the alarm control unit 46 transmits a fire-linked signal from any of the other home alarm devices belonging to the same alarm system as itself through the antenna 31 and the receiving circuit 44 of the wireless communication unit 30, in this case from the home alarm device 10-12. Is received, and when it is detected that it has been received effectively, an alarm sound such as “Woo-Wood another fire alarm has been activated is confirmed from the speaker 50 of the notification unit 36 as an alarm operation indicating the interlocking destination. The voice message “Please do” is repeatedly output, and the LED 22 is blinked, for example, to display an alarm indicating the interlocking destination. At the same time, the transmission circuit 42 is controlled to transmit an ACK signal as a response signal (reply) accompanying the reception of the fire interlock signal from the interlock source.

  When the alarm control unit 46 detects the operation of its own alarm stop switch 20 during the output of the fire alarm sound indicating the interlock source, the alarm control unit 46 controls the alarm unit 36 to output the alarm sound from the speaker 50 and the alarm display of the LED 22. While stopping the fire alarm operation by the output, control is performed to transmit the alarm stop interlocking signal from the transmission circuit 42 of the wireless communication unit 30 to another residential alarm device belonging to the same alarm system as itself, in this case, 10-12.

  While the alarm control unit 46 outputs the fire alarm sound indicating the interlock source, the alarm stop interlock signal from any of the other home alarm devices belonging to the same alarm system as the self, in this case, the home alarm device 10-12. When effective reception is detected, the alarm control unit 46 maintains at least one of the fire alarm sound and the fire alarm display without stopping control until at least a predetermined period elapses so that the interlock source can be identified.

  Further, the alarm control unit 46 operates either the alarm stop switch 20 during the output of the alarm sound indicating the interlocking destination, or any other home alarm device belonging to the same alarm system as itself, in this case from the home alarm device 10-12. When the effective reception of the alarm stop interlocking signal is detected, the notification unit 36 is controlled to stop the fire alarm operation by the alarm sound by the voice message from the speaker 50 and the alarm display of the LED 22.

  Furthermore, the alarm control unit 46 performs control to send back an ACK signal associated with reception of the alarm stop interlocking signal via the transmission circuit 42 as in the case of receiving the fire interlocking signal. 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. Note that the ACK signal transmission / reception processing can be similarly performed in communication between the residential alarm and the CATV adapter, which will be described later, but the description thereof is also omitted. In addition, communication retry, timeout processing, and the like can be performed as appropriate, but description thereof is omitted in this specification.

  In addition, the alarm control unit 46 is provided with a low battery failure monitoring function in which the power supply voltage supplied from the battery power supply 40 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 32 each time.

  Specifically, for example, the low battery failure monitoring is performed by reading the power supply voltage supplied from the battery power supply 40 at a predetermined measurement time interval (cycle), for example, at an interval of 4 hours, via the voltage monitoring circuit and setting the predetermined threshold voltage. A built-in test to be compared is performed, and when the battery voltage is lower than the threshold voltage, the low battery failure is preliminarily determined and stored in the memory 32, and when the low battery failure preliminary determination continues continuously a predetermined number of times, A battery failure is determined (determined) and detected, a low battery failure flag is set, and the memory 32 is updated and stored.

  Further, the alarm control unit 46 is provided with a sensor failure monitoring function for monitoring a failure (including component deterioration or failure) of the sensor unit 34, and is automatically executed periodically in the background as a built-in test. Specifically, for example, sensor failure monitoring is performed by reading a smoke detection signal output from the smoke detector 16 of the sensor unit 34 at a predetermined measurement time interval (cycle), for example, at an interval of 1 second, and holding the smoke detection signal in the memory 32. For every 10 minutes, for example, every 10 minutes, the average value of the detection data for the last 10 minutes held in the memory 32 is obtained, and when this average value falls below a predetermined reference level (referred to as zero point level) A failure of the sensor unit 34 is determined to be detected as being in a stopped state, and the sensor failure flag is set and updated and stored in the memory 32.

  When the alarm control unit 46 detects an inspection instruction operation (inspection instruction input) by operating the alarm stop switch 20 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 32. If it is determined that the low battery failure alarm or sensor failure alarm is output from the notification unit 36, the low battery failure interlock signal or the sensor failure interlock signal is output via the transmission circuit 42 of the wireless communication unit 30. A low battery fault alarm or a sensor fault alarm indicating a fault interlocking destination is output from the notification section 36 of the home police that has been transmitted to the other home police 10-12 and has effectively received it.

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

  Further, the alarm control unit 46 converts the fire cooperation interlocking signal received by the CATV adapter 100-1 from the CATV adapter 100-2 of the other house 24-2 via the CATV transmission path into the wireless communication protocol of the wireless communication path 11b, The fire cooperation interlocking signal transmitted to the home alarm devices 10-11 and 10-12 is received via the antenna 31 and the receiving circuit 44 of the wireless communication unit 30, and the received signal is decoded and effective reception is performed. When it detects, the other unit fire alarm is output from the alerting | reporting part 36 by cooperation interlocking | linkage.

  In addition, the fire cooperation interlocking signal effectively received by the home alarm device 10-11 is relay-transmitted as a fire interlocking signal to another housing alarm device in the same alarm system, in this case, the housing alarm device 10-12, if necessary. . The same applies to fire recovery, alarm stop, failure, etc., which will be described next, but will not be described.

  As the other unit fire alarm operation by this home alarm device 10-11, 10-12, for example, “Please confirm that the fire alarm of the unit B has been activated” Woo-woo repeats a voice message specifying the house 24-2. At the same time, the LED 22 is turned on to display a fire alarm. Here, similarly to the above, it is possible to specify and notify which dwelling unit of dwelling unit B has detected a fire.

  The alarm control unit 46 also outputs a fire recovery cooperation interlocking signal from the CATV adapter 100-2 of the other house 24-2 transmitted from the CATV adapter 100-1 via the antenna 31 and the receiving circuit 44 of the wireless communication unit 30. When receiving via the CATV transmission path and decoding the received signal and detecting effective reception, the fire recovery cooperation interlocking signal converted into the communication protocol of the wireless communication path 11b is transmitted to the transmission circuit 42 and the antenna of the wireless communication unit 30. The other dwelling unit fire alarm which is transmitted from 31 to the house alarm device 10-11, 10-12 and is output from the house alarm device which has received it effectively is stopped.

  Similarly, the alarm control unit 46 issues an alarm via the antenna 31 and the reception circuit 44 of the wireless communication unit 30 via the CATV adapter 100-2 and the CATV adapter 100-1 provided in the other house 24-2. When the stop cooperation interlocking signal is received and the reception signal is decoded and effective reception is detected, the other unit fire alarm output from the notification unit 36 is stopped by the cooperation interlocking.

  Similarly, the alarm control unit 46 causes a failure via the antenna 31 and the reception circuit 44 of the wireless communication unit 30 via the CATV adapter 100-2 and the CATV adapter 100-1 provided in the other house 24-2. When the cooperation interlocking signal is received, and when the reception signal is decoded and effective reception is detected, the other dwelling unit failure alarm output from the notification unit 36 is output by the cooperation interlocking.

  FIG. 4 is a block diagram showing an embodiment of an uplink / downlink conversion apparatus used in the present invention. In FIG. 4, the uplink / downlink conversion apparatus 300 separates the uplink cooperative signal of the uplink frequency f1 transmitted from the CATV adapter 100 and the uplink cooperative signal of the frequency f1 separated by the separator 302 with a predetermined oscillation frequency. The first-order frequency converter 304 that performs frequency conversion using the first-order frequency converter 304, the band-pass filter 310 that passes a signal of a predetermined frequency among the signals generated by the frequency conversion of the first-order frequency converter 304, and the band-pass filter 310 A secondary frequency converter 312 that further converts the frequency of the processed signal using a predetermined oscillation frequency, and a low frequency band f2 signal that passes through the signal generated by the frequency conversion of the secondary frequency converter 312. The signal that has passed through the low-pass filter 318 and the low-pass filter 318 is used as a downlink cooperative signal. And a mixer 320 for mixing the downlink signal from Doendo.

  The primary frequency converter 304 includes a mixer 306 and an oscillator 308, and the secondary frequency converter 312 includes a mixer 314 and an oscillator 316.

  Next, the operation of the uplink / downlink conversion apparatus 300 will be described. The separator 302 frequency-separates the upstream signal and extracts the upstream cooperative signal having the frequency f1 transmitted from the CATV adapter 100. The primary frequency converter 304 converts the frequency band signal separated and extracted by the separator 302, that is, the uplink cooperative signal (frequency f 1 = 45.75 MHz) transmitted from the CAT adapter 100, for example, the oscillation frequency F 1 (= 840 MHz) of the oscillator 308. ) To convert the frequency. By this frequency conversion, two signals having frequencies of f11 = F1−f1 (= 794.25 MHz) and f12 = F1 + f1 (= 885.75 MHz) are output.

  Here, the oscillation frequency F1 used in the primary frequency converter 304 is set so as not to fall within the range of the downlink frequency band assigned for the television common sound signal. By the way, as the downstream frequency band of the TV common signal, a band of 90 to 222 MHz for VHF and a band of 470 to 770 MHz for UHF are allocated.

  The band pass filter 310 passes only the signal of the frequency f12 out of the two signals output from the primary frequency converter 304, and blocks the signal of the frequency f11. For this reason, the signal having the frequency f 12 is input to the secondary frequency converter 312 by passing through the band-pass filter 310.

  The secondary frequency converter 312 converts the frequency f12 signal that has passed through the band-pass filter 310 using, for example, the oscillation frequency F2 (= 1270 MHz) generated by the oscillator 316. As a result, two signals with frequencies f21 = F2−f12 (= 384.25 MHz) and f22 = F2 + f12 (= 2155.75 MHz) are output. Here, the oscillation frequency F2 used in the secondary frequency converter 312 is also set so as not to fall within the range of the downstream frequency band of the TV common signal.

  The low-pass filter 318 passes only the signal of the frequency f21 out of the two signals output from the secondary frequency converter 312 and blocks the signal of the frequency f22. Here, when f21 = f2, the output of the secondary frequency converter 312 is passed through the low-pass filter 318, so that the signal of the frequency f2 is output to the mixer 320. The mixer 320 mixes the signal of the frequency f2 that has passed through the low-pass filter 318 with the downlink signal from the head end as a downlink cooperative signal.

  The frequency f2 (= 384.25 MHz) to be mixed by the mixer 320 matches the video frequency of 13 channels which are UHF vacant channels, and the downlink cooperation interlocking signal of the frequency f2 is received and demodulated by the CATV adapter 100 and cooperated. It is transmitted to the home alarm as an interlocking signal.

  Further, the frequency f2 of the downlink cooperative interlocking signal mixed by the mixer 320 is the frequency f1 of the uplink cooperative interlocking signal transmitted from the CATV adapter 100, the oscillation frequency F1 of the primary frequency converter 304, and the oscillation of the secondary frequency converter 312. It can be set arbitrarily by changing the frequency F2.

  Here, it is conceivable that the uplink cooperation interlocking signal transmitted from the CATV adapter 100 is directly converted to the frequency of the empty channel by the primary frequency converter 304 and the band filter 310, but the oscillation frequency of the primary frequency converter 304 is the television. May become a frequency band (90 to 770 MHz) assigned to the TV, which may affect the TV common signal. Therefore, in the present embodiment, frequency conversion is performed using an oscillation frequency higher than the frequency band (90 to 770 MHz) assigned to the television, and then the frequency band (90 to 770 MHz) assigned to the television is set. By performing frequency conversion again using another high oscillation frequency, assignment to a frequency corresponding to an empty channel is realized without affecting other television common-listen signals.

  FIG. 5 is a block diagram showing an embodiment of the CATV adapter 100-1 used in the present invention. This is an example, and the separation and integration of each function can be performed arbitrarily. In addition, any or all of the functions may be executed by software (program) or may be executed by hardware. FIG. 4 shows the CATV adapter 100-1, but the CATV adapter 100-2 has the same configuration.

  The CATV adapter 100-1 is provided with a processor 102, and the processor 102 is provided with a wireless communication unit 104, a CATV communication unit 106, and a power supply circuit unit 108 that communicate with the residential alarm. The power supply circuit unit 108 generates a predetermined DC power source from the commercial AC power source and supplies it to the necessary units, and maintains a power supply by switching to a standby power source device (not shown) when the commercial power source fails. Of course, other power supply configurations may be used. The wireless communication unit 104 corresponds to the alarm device communication unit in the claims.

  The wireless communication unit 104 is provided with a transmission circuit 110 and a reception circuit 112 connected to an antenna 114, and, like the wireless communication unit 30 of the home guard 10, an STD-30 known as a standard for a specific low power wireless station or Signals are transmitted / received to / from the home alarm according to a wireless communication protocol compliant with STD-T67.

  The CATV communication unit 106 is connected to a CATV transmission line via a TV terminal, and includes a CATV transmission circuit 116, a CATV reception circuit 118, and a mixer 120. The CATV transmission circuit 116 converts (modulates) the cooperation interlocking signal input from the processor 102 into, for example, an uplink cooperation interlocking signal having a frequency f1 (= 45.75 MHz), and transmits the signal to the CATV transmission line via the mixer 120.

  The CATV receiving circuit 118 receives and demodulates a downlink cooperative signal having a frequency f2 (= 475.75 MHz) transmitted after frequency conversion by the upstream / downstream apparatus 300 of FIG. 4 and outputs the cooperative cooperative signal as digital data to the processor 102. To do.

  The processor 102 is provided with the function of the protocol conversion unit 122, which decodes the interlocking signal received as the cooperation interlocking signal received from the home alarm device via the antenna 114 and the receiving circuit 112 of the wireless communication unit 104 and performs effective reception. If detected, a cooperative interlocking signal is generated (protocol converted) based on the received interlocking signal, and the CATV transmission circuit 116 of the CATV communication unit 106 is instructed to transmit as an upstream cooperative interlocking signal.

Generation of the linkage interlocking signal by the protocol converter 122 is event code 0001 = fire 0011 = alarm stop 0100 = recovery 0101 = sensor failure 0110 = low battery failure 0111 = other housing fire 1000 = Other dwelling unit alarm stop 1001 = Other dwelling unit restoration 1010 = Other dwelling unit sensor failure 1011 = Other dwelling unit low battery failure may be converted, and the event code is left as it is, and the event of other dwelling unit is identified. You may recognize that.

  Moreover, the address of the CATV adapter provided in the other dwelling unit which cooperates with an alarm is designated as a destination address. A plurality of addresses of this CATV adapter can be designated. Therefore, not only two dwelling units but also three or more dwelling units can perform alarm linkage.

  In addition, when the protocol conversion unit 122 decodes the downlink cooperation interlocking signal received by the CATV receiving circuit 118 of the CATV communication unit 106 and detects effective reception, the protocol conversion unit 122 generates a cooperation interlocking signal that does not include itself as a destination. Is transmitted to the home alarm device by instructing the transmission circuit 110 of the wireless communication unit 104.

  6 and 7 are flowcharts illustrating the outline of the processing of the home guard 10-11 in FIG. In this flowchart, the transmission / reception of the ACK signal and the processing accompanying it are omitted.

  In FIG. 6, when the power supply by the battery power source 40 of the mortgage guard 10-11 is started, initialization, self-diagnosis, reading of various settings, etc. are executed in step S1, and if there is no abnormality, the process proceeds to step S2. The presence or absence of fire detection is determined. If there is an initialization abnormality in step S1, the process of step S1 is performed again. If the initialization abnormality is repeated a predetermined number of times, the notification unit 36 notifies that fact and stops the operation halfway. Although not shown, the illustration is omitted.

  In step S2, when the smoke detection signal output from the smoke detector 16 provided in the sensor unit 34 exceeds a predetermined fire level, a fire is detected, and the process proceeds to step S3. It is generated and transmitted to other residential alarm devices (here, the residential alarm device 10-12, the same applies hereinafter) and the CATV adapter (here, the CATV adapter 100-1, the same applies hereinafter) belonging to the same group as the self, and a notification unit. The alarm operation which outputs the fire alarm which shows an interlocking origin by the alarm sound by a voice message etc. from 36 speakers 50 and the alarm display by LED22 lighting, for example is performed.

  Subsequently, in step S4, the presence or absence of a fire recovery in which the smoke detection signal from the smoke detector 16 is lowered and the fire detection state is resolved is detected. When a fire recovery is detected, the process proceeds to step S5, and as a fire recovery process, A fire recovery interlock signal is transmitted to the other residential alarm device 10-12 and the CATV adapter 100-1, and the fire alarm operation performed in step S3 is stopped. Here, the alarm display by the LED 22 may be turned off after a predetermined time has elapsed since the alarm sound stopped.

  Subsequently, in step S6, it is determined whether or not an alarm stop instruction is detected by the alarm stop switch 20. When switch operation is detected as an alarm stop instruction input, the process proceeds to step S7, and an alarm stop interlock signal is displayed as an alarm stop process. While transmitting to the alarm device 10-12 and the CATV adapter 100-1, the alarm sound output which shows the link origin from the own speaker 50 is stopped, and the alarm display by lighting of LED22 is extinguished. In this case, the alarm display by the LED 22 may be turned off after a predetermined time has elapsed since the alarm sound stopped.

  Then, it progresses to step S8 and it is discriminate | determined the presence or absence of the effective reception detection of the fire interlocking | linkage signal transmitted or relay-transmitted from the resident guard 10-12. When a fire-linked signal effective reception from any of the house alarms (here, the house alarm 10-12, the same applies hereinafter) is detected, the process proceeds to step S9, and the speaker of the self-notification unit 36 is operated as a linked fire alarm process. An interlocking alarm operation is performed by outputting an alarm sound such as a voice message from 50 and displaying an alarm by blinking the LED 22, for example. At this time, relay transmission or re-relay transmission to other mortgages is performed as necessary, but the description is omitted. Steps S11 and S13 described later are similarly omitted.

  Next, it is determined whether or not the effective reception detection of the fire recovery interlocking signal transmitted or relayed from the home police device 10-12 is detected in step S10, and when the effective reception of the fire recovery interlocking signal is detected, the process proceeds to step S11. As the linked fire recovery process, the linked destination alarm operation performed in step S9 is stopped.

  Next, the process proceeds to step S12 in FIG. 7, where it is determined whether or not the alarm stop interlocking signal is effectively received or transmitted from the home alarm device 10-12, and when the alarm stop interlocking signal is effectively received, Proceeding to step S13, the interlocking destination alarm operation performed in step S9 is stopped as the interlocking alarm stop process.

  Subsequently, the process proceeds to step S14, which is one of the alarm devices of any of the other houses (here, the house 24-2; the same applies hereinafter) transmitted from the CATV adapter 100-1 (here, for example, the alarm device 10-21). Whether the effective reception detection of the fire cooperation interlocking signal via any one of the CATV adapters provided in other houses (here, the CATV adapter 100-2, the same applies hereinafter) based on the fire detection of the following) is detected. When the effective reception of the fire cooperation interlocking signal is detected, the process proceeds to step S15, and the speaker 50 of the self-notification unit 36 is used as a fire alarm process (another dwelling unit (other system) alarm operation) interlocking with the dwelling unit. The other unit fire alarm sound by voice message etc. is output from, for example, while the alarm display by blinking of the LED 22 is performed, for the housing alarm device 10-12 as necessary Or relays the fire linkage interlock signal received from the CATV adapter 100-1, or generates and sends a fire interlock signal. At the same time, an ACK signal accompanying the reception of the fire cooperation interlocking signal is returned to the CATV adapter 100-1, but detailed description thereof is omitted.

  Subsequently, the process proceeds to step S16, and any one of the alarm devices of the house 24-2 transmitted from the CATV adapter 100-1 in the same manner as in the case of the fire cooperation interlocking signal described in step S14 (here, for example, the residential alarm device 10- 21. The same shall apply hereinafter.) The presence / absence of effective reception detection of the fire recovery cooperation interlocking signal based on the fire recovery detection is determined, and when the effective reception of the fire recovery cooperation interlocking signal is detected, the process proceeds to step S17. As the fire recovery process, the other dwelling unit alarm operation performed in step S15 is stopped.

  Subsequently, the process proceeds to step S18, and the alarm stop based on the alarm stop operation detection of the alarm device 10-21 of the house 24-2 transmitted from the CATV adapter 100-2 in the same manner as in the case of the fire cooperation interlocking signal described in step S14. Whether or not the effective reception of the cooperation interlocking signal is detected is determined, and when the effective reception of the alarm stop cooperation interlocking signal is detected, the process proceeds to step S19, and the other unit fire alarm sound is stopped as the cooperation interlocking alarm stop processing. Stops alarm display due to blinking. At the same time, as in step S15, an alarm stop interlocking signal in the corresponding house is transmitted to the residence police device 10-12 in the house 24-1 (or relayed and transmitted). The device 10-12 is also caused to stop the alarm operation.

  Then, it progresses to step S20, and when the low battery failure or the sensor failure is detected by the home police device 10-11 itself, or the failure interlocking signal indicating the low battery failure or the sensor failure from another home watch device 10-12 is valid. When reception is detected, the process proceeds to step S21, and as a failure alarm process (failure alarm operation), a low battery failure alarm or a sensor failure alarm indicating the linkage source or the linkage destination is performed with an alarm sound and an alarm display.

  Although not shown, the failure based on the failure detection of the alarm device 10-21 of the house 24-2 transmitted from the CATV adapter 100-1 in the same manner as in the case of the fire cooperation interlocking signal described in step S14. When it is determined whether or not the effective reception of the cooperation interlocking signal is detected, an alarm sound such as a voice message is output from the speaker 50 of the self-notification unit 36 as a cooperation destination failure alarm operation, and an alarm display by blinking of the LED 22, for example, is performed. .

  The restoration and stop of the failure alarm operation and the cooperation failure cooperation operation can be performed in the same manner as the fire recovery and alarm stop processing, but illustration and description thereof are omitted.

  In addition, although said embodiment took the alarm cooperation of the alarm system installed in 2 houses as an example, it links | links an appropriate number of house alarm systems, such as 3 houses and 4 houses, as needed. Can do. The alarm system arranged in each house may be composed of one alarm device for each house, or three or more alarm devices can be linked. When there is one alarm device of the alarm system, the alarm device does not need to be provided with an interlocking function with other alarm devices. Regarding the CATV adapter, at least one CATV adapter may be provided for each house (alarm system), and the number of units is not limited.

  In addition, the alarm system in the above embodiment was an example of an alarm system composed of a residential alarm that detects and alerts a fire as an abnormality, but a fire alarm other than a residential alarm, a gas leak alarm, The same applies to CO alarms, various security alarms, earthquake alarms (emergency earthquake broadcast receivers, etc.), other alarm systems with arbitrary alarms, and alarm systems with a mixture of these alarms. Applicable to. Furthermore, the present invention can be applied to a system including a relay device and a receiving device in addition to these alarm devices.

  In addition, the residential alarm device 10-11 in FIG. 3 is provided with a smoke detection unit 16 and takes a smoke fire alarm as an example to detect smoke generated by a fire and detect a fire in the monitoring area.
