Description

The present invention relates to an alarm system that outputs an alarm sound in conjunction with another place when an alarm device detects an abnormality such as a fire in a monitoring area and outputs an alarm sound.

  2. Description of the Related Art Conventionally, an alarm device that detects and warns of a fire in a house or the like has become widespread. Of these, residential fire alarms are referred to as residential alarms.

  For example, in such a house alarm, it is operated by a battery power source, and a sensor part for detecting a fire and an alarm part for alarming a fire are integrated in the house alarm, and a fire is generated based on a detection signal of the sensor part. When a fire alarm is detected, a fire alarm sound of a predetermined pattern is output from the alarm unit, and a fire monitor and alarm notification can be performed by a single residential alarm without the need for a receiver or the like as in the so-called automatic fire alarm equipment. It is simple and inexpensive, and it has become widespread with the obligatory installation in ordinary houses.

  A home alarm device that detects a fire with the sensor unit and outputs a fire alarm sound from the alarm unit is known as a stand-alone type. When a fire alarm sound is output from the alarm device, a wireless interlocking house alarm device that outputs a fire alarm sound in conjunction with other housing alarm devices has also been put into practical use and has become widespread.

  At present, most of the residential alarms installed in ordinary houses are stand-alone type, and multiple residential alarms are installed in the kitchen, living room, children's room, bedroom, staircase, etc. And monitoring the fire.

  When multiple stand-alone house alarms are installed separately for each room in this way, even if the house alarm detects a fire in one room and outputs an alarm sound, the volume is sufficient in another room. However, in order to solve this problem, it is only necessary to install a radio-linked house guard.

  However, stand-alone and wireless interlocked home guards, for example, guarantee a battery life of more than 10 years. If a stand-alone home guard is already installed, the wireless interlocked home guard is replaced. Changing to a warning device is a situation that cannot be easily done in reality, even if you are fully aware of the advantages of the wireless link type.

  Therefore, when the stand-alone house alarm is equipped with a transfer circuit part, an interlock alarm adapter is connected to the transfer circuit part by a signal line, and the transfer circuit part accompanying the output of the alarm sound of the house alarm A system that detects a transfer signal from the station and sends a fire-linked signal to a wireless-linked dwelling device installed in another room to give a linked alarm.

  However, some existing stand-alone dwelling alarms do not have a message transfer circuit unit, and there are cases where the interlocking alarm adapter cannot be used. Further, even if the stand-alone type house alarm device includes the transfer circuit unit, the interlock alarm adapter cannot be connected to the signal line circuit unit of the house alarm device if the manufacturer is different.

  Even if the manufacturer is the same, depending on the version of the product, the interlock alarm adapter cannot be connected to the signal line due to the difference in the connector structure of the transfer terminal, and it is necessary to prepare a compatible intermediate connector. In addition, it is a burden for users who do not have specialized knowledge to connect the interlocked alarm adapter to the home alarm, and there is a problem that even if there is an interlocked alarm adapter, it is difficult to use it. ing.

[Configuration of alarm system A]
(Outline of system configuration)
FIG. 1 is an embodiment showing installation of an alarm system A according to the present invention to a house. The alarm system A of the present invention includes a stand-alone first residential alarm 10 (10-1 to 10-5), an interlocked alarm. It comprises an adapter 12 (12-1, 12-2, 12-3) and a wireless interlocking second home alarm device 14.

  The first home alarm device 10 (10-1 to 10-5) is a first alarm unit that detects an abnormality in a monitoring area such as each room and outputs an abnormality alarm sound. The interlocking alarm adapter 12 (12-1, 12-2, 12-3) is disposed in the same monitoring area as the first alarm means, and is abnormal when an abnormal alarm sound output from the first alarm means is detected. The interlock alarm means transmits an interlock signal and outputs an abnormal alarm sound indicating the interlock destination when an abnormal interlock signal is received from another interlock alarm means or the second alarm means. Further, the second dwelling alarm 14 detects an abnormality in a monitoring area different from the monitoring area of the first alarm means, outputs an abnormality alarm sound indicating the interlocking source, and transmits an abnormality interlocking signal. Or it is the 2nd alarm means which outputs the abnormal alarm sound which shows an interlocking destination, when the abnormality interlocking signal from another 2nd alarm means is received.

  The minimum configuration of the alarm system A includes a first home alarm 10, an interlocking alarm adapter 12, and a second home alarm 14. In the following description, a case where a fire alarm is output as an abnormality alarm will be described as an example.

(Arrangement of home alarm)
In FIG. 1, the stand-alone first dwelling devices 10-1 to 10-5 are installed in each room such as a kitchen, a child's room, a bedroom, and a staircase in the house 16. Taking the first dwelling unit 10-1 of the kitchen as an example, the first dwelling unit 10-1 observes the temperature or smoke concentration of the kitchen and detects a fire based on the temperature or smoke concentration indicated by the observation result. In this case, a fire alarm sound is output and a fire alarm is displayed.

(Arrangement of interlocking alarm adapter and second housing alarm)
The alarm system A in FIG. 1 is in a state in which the first home alarm devices 10-1 to 10-5 are already installed, and the alarm system is linked, for example, the first home alarm device 10 in the kitchen and the child room. Corresponding alarm adapters 12-1 to 12-3 are arranged corresponding to -1 to 10-3, and a second dwelling alarm 14 is arranged in the living room.

  The interlocking alarm adapters 12-1 to 12-3 can obtain a sound pressure of 70 dB or more in close proximity, for example, according to the standard, where the fire alarm sound output by the first home alarm devices 10-1 to 10-3 can be detected. Place within 1 meter.

  In addition, hereinafter, when the first house alarm devices 10-1 to 10-5 and the interlocking alarm adapters 12-1 to 12-3 are not distinguished from each other, they are referred to as the first house alarm device 10 and the interlocking alarm adapter 12.

  Originally, the second home alarm 14 is configured to construct a wireless interlocking alarm system by arranging a plurality of second home alarms in each room. In the alarm system of the present invention, 2 When a wireless interlocking system is built based on the stand-alone first residential guard 10 using the wireless communication function and alarm output function of the residential guard 14, the fire interlock signal from the alarm interlocking adapter 12 is sent. It is used as a notification device that receives and outputs a fire alarm.

  In addition, when installing the second home alarm device 14 in the living room, the second alarm device 14 has an original function of detecting and alarming a fire. If it has already been installed, the first home alarm device 10 is removed and a second home alarm device 14 is newly installed.

  The schematic operation of the alarm system A will be described. For example, when a fire is detected by the first residential alarm 10-1 installed in the kitchen and a fire alarm sound is output, the fire alarm sound is connected to the interlock alarm adapter 12-1. To the second house alarm 14 installed in the living room and the interlock alarm adapters 12-2 and 12-3 installed in the child room together with the first house alarms 10-2 and 10-3. The second home alarm 14 and the interlocking alarm adapters 12-2 and 12-3 receive the fire interlocking signal from the interlocking alarm adapter 12-1 and output a fire alarm sound indicating the interlocking destination.

  Between the interlocking alarm adapters 12-1 to 12-3 and the second dwelling alarm 14 and between the interlocking alarm adapters 12-1 to 12-3 is a communication path 11 according to a predetermined communication protocol. The adapter 12-1 transmits a fire interlocking signal including a group code unique to the alarm system to the second home alarm 14 and other alarm interlocking adapters 12-2 and 12-3 via this route. A plurality of second home alarms 14 may be arranged as necessary.

[Configuration of the first home alarm]
FIG. 2 is a block diagram showing an outline of the functional configuration of the first home alarm device 10-1, and the same applies to the other first home alarm devices 10-2 to 10-5.

  In FIG. 2, the first home alarm device 10-1 includes an alarm control unit 18, a sensor unit 20, a notification unit 22, and an operation unit 24, and operates with a battery power source (not shown).

  The alarm control unit 18 is a function realized by executing a program, for example. As hardware, a CPU, a memory, a computer circuit provided with various input / output ports, or a wired logic circuit is used.

  The sensor unit 20 is a temperature detection unit or a smoke detection unit. When a temperature detection unit is provided as the sensor unit 20, for example, a thermistor is used as the temperature detection element. In this case, a voltage detection signal corresponding to a change in resistance value due to temperature is output to the alarm control unit 18. Further, when a smoke detector is provided as the sensor 20, a known scattered light smoke detector structure is provided, and a light emitter using an infrared LED is intermittently driven to emit light at a predetermined cycle according to an instruction from the alarm controller 18. The light receiving signal of the scattered light received by the light receiving unit such as a photodiode is amplified, and the smoke density detection signal is output to the alarm control unit 18.

  The notification unit 22 includes a speaker, an LED, and respective drive circuits, and outputs an alarm sound from the speaker according to an instruction from the alarm control unit 18 as necessary, and displays an alarm with the LED. The operation unit 24 includes various switches such as an alarm stop switch that receives an operation for stopping an alarm sound and / or an alarm display.

  The alarm control unit 18 is a function realized by CPU program execution and performs fire alarm control, fire recovery control, alarm stop control, and the like.

  The alarm control unit 18 reads the temperature or smoke density detection signal output from the sensor unit 20 by AD conversion, detects fire when it is equal to or higher than a predetermined threshold, and performs control to output a fire alarm from the notification unit 22. The fire detection may be performed when the change rate is obtained from the temperature or smoke density detected over a plurality of times and this change rate (increase rate) is equal to or higher than a predetermined change rate threshold value. In addition, a fire may be detected by various calculations based on temperature or smoke density.

  As a fire alarm in this case, for example, a fire alarm sound such as “It is a fire.” Is repeatedly output from the speaker, and the LED is turned on, for example, to display a fire alarm. Here, the “Peepy” portion of the fire alarm sound is a sweep sound that changes the frequency in a range from about 2 KHz to about 3 KHz, for example. The sound pressure of the fire alarm sound is equal to or higher than a predetermined sound pressure defined in the standard, for example, a sound pressure of 90 dB / m.

  In addition, the fire alarm sound is a voice message such as “Pew Pew Fire is Fire” or “Ph Hugh Hue Fire is Fire” if the manufacturer is different from this, but both range from about 2 KHz to about 3 KHz. It is common to include a sweep sound that changes the frequency in accordance with the standard.

  The alarm control unit 18 recovers a fire when the temperature or smoke density falls below the threshold value based on the detection signal of the sensor unit 20 for a predetermined time, or for example, continues for a predetermined number of times (fire detection state has been eliminated). And instructing the notification unit 22 to perform a control to stop the fire alarm output.

  When the alarm control unit 18 detects an alarm stop operation received by the alarm stop switch of the operation unit 24 during the output of the fire alarm, the alarm control unit 18 instructs the notification unit 22 to stop the fire alarm output.

  The alarm control unit 18 monitors a low battery failure or a sensor failure that causes the battery voltage to be less than a predetermined level. When the low battery failure is detected, the alarm control unit 18 instructs the notification unit 22 to provide, for example, a low battery failure alarm. Control is performed to output an alarm sound such as “Battery is dead” and LED is lit or blinked. In addition, when detecting a sensor failure, the alarm control unit 18 instructs the notification unit 22 to output an alarm sound such as “beep” as a sensor failure alarm and to control to turn on or blink the LED. Such a failure alarm sound does not include a sweep sound like a fire alarm sound, and the sound pressure is sufficiently lower than the fire alarm sound, and the interlocking alarm adapter 12 can be easily distinguished. There is no such thing as sending a fire-linked signal by misdetecting the sound.

[Configuration of linked alarm adapter]
FIG. 3 is a block diagram showing an outline of the functional configuration of the interlocking alarm adapter 12-1, and the other interlocking alarm adapters 12-2 and 12-3 are the same.

  In FIG. 3, the interlocking alarm adapter 12-1 includes an alarm sound detection unit 28, an interlocking control unit 26, a communication unit 30 connected to an antenna 32, and a notification unit 34, and operates with a battery power source (not shown). The interlock control unit 26 is a function realized by executing a program, for example. As hardware, a CPU, a memory, a computer circuit provided with various input / output ports, or a wired logic circuit is used.

  The communication part 30 transmits / receives a signal according to a predetermined | prescribed communication protocol between the 2nd residential alarm 14 and the other interlocking alarm adapters 12-2 and 12-3. As this communication protocol, in Japan, for example, STD-30 (radio equipment standard of a low power security system radio station) or STD-T67 (known as a standard of a specific low power radio station of 400 MHz band) Compliant with specified low-power radio station telemeter, telecontrol and data transmission radio equipment standards). This signal has a format including a transmission source code indicating a transmission source, a group code, a control command, and the like.

  The alarm sound detection unit 28 detects the fire alarm sound output from the first home alarm 10, but in particular, the volume of the fire alarm sound is substantially constant and the frequency changes in a range of, for example, about 2 KHz to about 3 KHz. A sweep sound is detected and an alarm sound detection signal is output to the interlock control unit 26.

  For this reason, the alarm sound detection unit 28 includes a microphone for converting the alarm sound into an audio signal, a band filter having a passband frequency of, for example, about 2 KHz to about 3 KHz corresponding to the sweep sound among the audio signals from the microphone, and a band filter. And a circuit such as an amplifier for amplifying the signal extracted in step (b) and a comparator for outputting when the predetermined threshold level of the amplified sound signal is exceeded, and outputs an alarm sound detection signal based on the sound signal corresponding to the sweep sound.

  Here, the fire alarm sound of the first mortgage alarm 10 is “Peep fire fire”, and the alarm sound detection unit 28 detects the sweep sound of the fire alarm sound of “Peepy fire” and alarms it. The sound detection signal is output to the interlock control unit 26.

  Also, even if the fire alarm sound output by the 1st Dwelling Unit 10 due to a difference in the manufacturer is, for example, “Pew Pew Fire is Fire” or “P Hugh Hue Fire is Fire”, both are about 2KHz to about 3KHz. The alarm sound detection unit 28 detects a sweep sound such as “Pew Pew” or “Pie Hugh Hugh” that changes the frequency in the range up to and outputs an alarm sound detection signal to the interlock control unit 26.

  For this reason, when the manufacturer of the 1st home guard 10 differs, and even if it is the same manufacturer, the fire which the 1st home guard 10 outputs without being influenced by such a difference is different. An alarm sound can be detected and an alarm sound detection signal can be output.

  In addition, the alarm sound detection unit 28 can exclude the failure alarm sound from the detection target without outputting the alarm sound detection signal, for example, for the failure alarm sound other than the fire alarm sound that does not include the sweep sound.

  When the interlock control unit 26 reads the alarm sound detection signal output from the alarm sound detection unit 28 and detects a fire alarm sound, the interlock control unit 26 generates a fire interlock signal according to a predetermined communication protocol, and instructs the communication unit 30 to The control which transmits is performed, and the fire alarm which shows an interlocking | linkage destination is output by the 2nd house alarm device 14 which received the said fire interlocking signal, and the other interlocking alarm adapters 12-2 and 12-3.

  In addition, the interlock control unit 26 detects the fire alarm sound output from the first home alarm 10 and transmits a fire interlock signal, and then fire alarm sound accompanying the fire recovery or alarm stop operation of the first home alarm 10. When the stop is detected, the alarm stop interlocking signal according to the predetermined communication protocol is generated, and the communication unit 30 is instructed to transmit the control signal. The other alarm alarm adapters 12-2 and 12-3 stop the output of the fire alarm indicating the interlock destination.

  Note that the alarm sound output from the first home alarm 10 is a loud alarm sound that does not occur in daily life, so the alarm sound detection unit 28 detects the sweep sound in the fire alarm sound. Not only the detection but also the fire alarm sound itself may be detected and an alarm sound detection signal may be output. The alarm sound detection unit 28 in this case includes a microphone that converts the alarm sound into an audio signal, an amplifier that amplifies the audio signal from the microphone, and a comparator that outputs when a predetermined threshold level of the amplified audio signal is exceeded. It is not necessary to provide a bandpass filter for extracting the sweep sound. The microphone may be a low-sensitivity microphone because the fire alarm sound is loud.

  In addition, the house alarm 10 outputs a test fire alarm sound with a slightly reduced volume when a predetermined test operation is performed. The alarm sound detection unit 28 detects the test fire alarm sound. An alarm sound detection signal is output so that an interlocking test can be performed along with the test operation of the residential alarm 10.

  The notification unit 34 includes a speaker, an LED, and respective drive circuits, and outputs an alarm sound from the speaker according to an instruction from the interlock control unit 26 as needed, and displays an alarm with the LED. Here, by combining the microphone provided in the alarm sound detection unit 28 and the speaker provided in the notification unit 34, it is possible to reduce the size and cost of the adapter.

  The alarm interlock adapter 14 is provided with an operation unit having various switches such as a report stop switch, and the interlock control unit 26 generates an alarm stop interlock signal when detecting the alarm stop operation received by the alarm stop switch. The communication unit 30 is instructed to transmit, and the second alarm unit 14 and the other interlocked alarm adapters 12-2 and 12-3 that have received the alarm stop interlocking signal output a fire alarm indicating the interlocking destination. May be stopped.

[Configuration of the second home alarm]
FIG. 4 is a block diagram showing an outline of a functional configuration of the wireless interlocking second home alarm device 14. In FIG. 4, the second home alarm 14 includes an alarm control unit 35, a sensor unit 36, a communication unit 38 including an antenna 40, a notification unit 42, and an operation unit 44, and operates with a battery power source (not shown).

  The alarm control unit 35 is a function realized by executing a program, for example. As hardware, a CPU, a memory, a computer circuit provided with various input / output ports, or a wired logic circuit is used.

  Since the sensor part 36, the alerting | reporting part 42, and the operation part 44 are the same as the case of the sensor part 20, the alerting | reporting part 22, and the operation part 24 of the 1st home guard 12-1 of FIG. Omitted.

  The communication unit 38 receives a fire interlock signal from the interlock alarm adapter 12 according to a predetermined communication protocol. As in the case of the communication unit 30 in FIG. 3, this communication protocol is, for example, STD-30 (a low power security system radio station standard) known as a standard for a specific low power radio station in the 400 MHz band. It conforms to STD-T67 (standard specification for radio equipment for specific low power radio station telemeter, telecontrol and data transmission). This fire interlocking signal has a format including a transmission source code indicating a transmission source, a group code, a control command, and the like.

  The alarm control unit 35 is a function realized by CPU program execution, and performs the following fire alarm control, linked disaster alarm control, alarm stop control, and the like.

(Fire alarm control)
The alarm control unit 35 reads the temperature or smoke density detection signal output from the sensor unit 36 by AD conversion, detects a fire when the value is equal to or higher than a predetermined threshold, and outputs a fire alarm indicating the interlock source from the notification unit 44. Take control. As a fire alarm in this case, for example, a voice message such as “It is a fire.

  Moreover, the alarm control part 35 produces | generates a fire interlocking | linkage signal, when the disaster alarm is output from the alerting | reporting part 42, instruct | indicates to the communication part 38, and other 2nd living alarm and alarm interlocking adapters 12-1-12. -3 is controlled to transmit a fire interlocking signal, and a fire alarm indicating the interlocking destination is output by the other second residential alarm and the alarm interlocking adapters 12-1 to 12-3 that have received the fire interlocking signal.

  In this case, as a fire alarm indicating the interlocking destination, for example, a fire alarm sound such as “please confirm that another alarm device has been activated” is repeatedly output from the speaker and the LED is turned on, for example.

  Moreover, the alarm control part 35 is a control which outputs the fire alarm which shows the interlocking | linkage destination from the alerting | reporting part 42, when the effective reception of the fire interlocking signal which the other 2nd dwelling alarm device transmitted via the communication part 38 is detected. I do. In addition, in the alarm system of this invention, since the other 2nd home alarm is not arrange | positioned, the fire interlocking alarm by the several 2nd home alarm 14 is not performed.

  Moreover, the alarm control part 35 shows the interlocking destination from the alerting | reporting part 42, when the effective reception of the fire interlocking signal which any of the interlocking alarm adapters 12-1 to 12-3 transmitted via the communication part 38 is detected. Control to output a fire alarm. In this case, the fire alarm indicating the interlocking destination is also performed by repeatedly outputting a fire alarm sound from the speaker, for example, “Please check if another alarm device has been activated” and turning on the LED, for example.

  Further, the alarm control unit 35 detects, for example, “PPP No. 1 as a fire detection alarm” as a fire-linked alarm when the effective reception of the fire-linked signal transmitted by the linked alarm adapter 12-1 is detected via the communication unit 38. It is also possible to control to turn on the LED, for example, while repeatedly outputting a fire alarm sound from the speaker. Here, “No. 1” is information that identifies, for example, the first residential alarm 10-1 that has detected a fire.

  That is, in the fire interlocking signal transmitted from the interlocking alarm adapter 12-1 to the second housing alarm 14 and the interlocking alarm adapters 12-2 and 12-3 by detecting the fire alarm sound of the first residential alarm 10-1. The code | symbol (transmission source code | cord | chord) for specifying the interlocking alarm adapter 12-1 of a transmission source is contained. And the code | symbol which identifies each interlocking | linkage alarm adapter 12-1 and the content of the fire alarm sound are linked | related within the memory of the 2nd dwelling alarm device 14 by the initial setting etc. FIG. For this reason, the house alarm which output the fire alarm as mentioned above is recognized, and the fire alarm sound of the fire interlocking alarm can be made to include the information indicating the installation location, for example.
