Description

  The present invention relates to an alarm system that spot-observes the temperature of a device or a local area that can be a fire source in a monitoring area, and detects an alarm such as a fire to alarm.

  Conventionally, alarm devices that detect and warn of abnormalities such as fires in homes and the like have 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 the house alarm is integrally provided with a sensor part for detecting a fire and an alarm part for alarming the fire, and 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 it is possible to perform fire monitoring and alarm notification with a single residential alarm without requiring a receiver such as a so-called automatic fire alarm facility. It is simple and inexpensive, and it has become widespread with the obligatory installation in ordinary houses.

  In addition, by communicating between multiple home alarms, when a fire alarm sound is output from any home alarm, other home alarms also output a fire alarm sound in conjunction with the other home alarm. Alarms are also in practical use and are becoming popular.

  Many of the places where fires occur are places where fires such as various stoves and gas stoves are used, places where fires are used for smoking, waste bins, etc. In the case of arson, they are places where garbage is collected. In order to detect fires occurring in such places early, it is only necessary to install residential alarms at or near these places. It is installed on the ceiling surface and the upper part of the wall surface overlooking the entire monitoring area, and it is not designed to monitor the fire in a spot manner by narrowing the place further in this monitoring area.

  In order to solve this, it is unreasonable to arrange the home alarms in each region because the number of installed home alarms increases.

  As another method of spotting a fire, for example, a temperature sensor is installed locally to be monitored, a fire is detected based on information (signal) from this temperature sensor using a separate receiver, etc. It is only necessary to perform notification by or display. In this case, however, local monitoring becomes possible, but it becomes difficult to monitor fires occurring in other areas. In addition, it is difficult to confirm whether or not the entire predetermined monitoring area can be covered as a result of arranging the temperature sensors in a plurality of local areas where the predetermined monitoring area covered by one residential alarm is subdivided.

  On the other hand, for example, a hot air current (or smoke particles carried to the installation wall, etc.) reaches the installation wall surface or ceiling surface until it detects a fire that has occurred in a specific device or a specific local area within a predetermined monitoring area. Since this is detected, a fire is detected. For this reason, it takes a certain amount of time until a fire is detected after a fire actually occurs (after a fire source is generated). Therefore, it is expected that a fire cannot always be detected with high sensitivity (short time) depending on the positional relationship between the place where the house alarm is installed and the fire source and other conditions.

  In addition, since the home alarm cannot detect a fire outside the preset monitoring area, if you want to monitor a fire outside the monitoring area, the local area is narrower than the monitoring area. Even if there is, there is no choice but to provide another house alarm, but this is not always appropriate in terms of cost, for example.

The present invention solves the above-mentioned problems, and in order to realize unprecedented convenience in the alarm system, the function of the home alarm is provided by the cooperation between the home alarm and the miniaturized wireless temperature measuring chip. Reinforce and supplement, spot and observe specific equipment and local temperatures that are expected to become fire sources inside and outside the monitoring area of the home alarm, and detect abnormalities such as fires to alarm The purpose is to provide an alarm system.

(Appearance and structure of temperature measurement chip)
FIG. 2 is an explanatory view showing the appearance of the temperature measuring chip provided in FIG. 1. FIG. 2A is a plan view, FIG. 2B is a cross section of the internal structure, and FIG. Show.

  In FIG. 2, the temperature measuring chip 10 is molded with, for example, a synthetic resin and opened with a disc-shaped cover 18 opened at one end (lower side of FIG. 2B), and a base 20 mounted on the opening side of the cover 18. The circuit board 22 is accommodated in the housing.

  A button battery 24 is accommodated between the circuit board 22 and the base 20, a positive terminal fitting 32 is in contact with the positive electrode of the button battery 24, and a negative terminal fitting 30 is in contact with the negative electrode of the button battery 24.

  The button battery 24 is fixed by attaching a battery lid 26 to the opening hole of the base 20. The battery lid 26 is formed by forming L-shaped fitting protrusions at two opposite positions on the outer periphery and inserting the fitting protrusions into the fitting cutouts formed in the opening of the base 20 to lock the battery lid 26. The battery cover 26 is formed with a fitting groove 28 for fitting a coin or the like for a turning operation when the button battery 24 is attached or detached.

  A control chip 38 and a wireless communication chip 40 are mounted on the upper side surface of the circuit board 22, and a temperature detection element 36 is mounted inside a slit (opening) 42 formed in the cover 18 at a position where outside air flows. doing. As the temperature detection element 36, an appropriate temperature detection element such as a thermistor whose resistance value changes according to the temperature of the observation point (heat sensitive part) is used.

In addition, an attachment means and a method are arbitrary, In addition to the attachment sheet | seat 34, appropriate means, such as a hook, a clip, a string, can be provided as needed.

(Functional configuration of temperature measurement chip)
FIG. 3 is a block diagram showing an outline of the functional configuration of the temperature measurement chip.
The temperature measuring chip 10 includes a temperature detecting element 36, a temperature measuring control unit 48, and a communication unit 50 connected to an antenna 52, and operates by receiving power supply from the button battery 24 shown in FIG. The temperature measurement control unit 48 corresponds to the control chip 38 of FIG. 2 and 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 unit 50 corresponds to the wireless communication chip 40 in FIG. 2 and transmits and receives signals to and from the migration adapter 200 according to a predetermined first wireless communication protocol. As the first wireless communication protocol, for example, a short-range wireless communication protocol for a sensor network using a frequency of 900 MHz assigned to RFID (Radio Frequency IDentification “abbreviation of individual identification by radio wave”), that is, 950 to 957 MHz is used. To do.

  As described above, the temperature detection element 36 uses, for example, a thermistor, and in this case, a temperature detection signal (for example, a voltage detection signal) corresponding to a change in resistance value due to temperature is output to the temperature measurement control unit 48.

  The temperature measurement control unit 48 measures and transmits the temperature in accordance with an instruction from the transfer adapter 200 described later, for example. That is, when a batch AD conversion signal transmitted from the transfer adapter 200 at every predetermined period is effectively received, the temperature is acquired based on the detection signal from the temperature detection element 36, and then transmitted to the own address (for example, When a polling signal specifying its own transmission source code is received effectively, control is performed so that a temperature measurement signal including the acquired temperature is transmitted from the communication unit 50 to the transition adapter 200 via the transition signal line. .

  Thus, by acquiring and transmitting the temperature according to the instruction from the transfer adapter 200, it is possible to avoid collision (transmission failure) of the temperature measurement signals transmitted from the plurality of temperature measurement chips 10. Also, the temperature acquisition timings of the plurality of temperature measurement chips 10 can be matched.

  Note that the temperature measurement control unit 48 may voluntarily measure the temperature at every predetermined period and transmit a temperature measurement signal including the measured temperature, regardless of an instruction from the transfer adapter 200. In this case, in order to avoid a collision with a temperature measurement signal transmitted from another temperature measurement chip, carrier sense is performed and transmission is performed at a timing without a carrier.

[Transfer adapter]
FIG. 4 is a block diagram showing a schematic configuration of the transfer adapter 200.

  In FIG. 4, a message adapter 200 includes a message controller 202, a communication unit 204 connected to an antenna 206, and a message transmitter 208, and is operated by a battery power source (not shown).

  The transfer control unit 202 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 unit 204 receives an instruction from the transfer control unit 202 and transmits / receives a signal to / from the temperature measurement chip 10 according to the first wireless communication protocol. This signal has a format appropriately including information such as a transmission source code indicating a transmission source, a group code indicating a monitoring group, a batch AD conversion command, a polling command, and a measured temperature. The aforementioned temperature measurement signal corresponds to this signal. The transfer adapter 200 forms a monitoring group for transmitting and receiving signals with the temperature measurement chip 10 according to the first wireless communication protocol. The first wireless communication protocol of the communication unit 204 is the same as that of the communication unit 50 provided in the temperature measurement chip 10 of FIG.

  The message transmission unit 208 is connected to the alarm device 100-1 through the signal signal line, receives an instruction from the message control unit 202, and sends a temperature error message or a temperature error recovery signal to the alarm device 100-1. Send. As described above, this transmission may be wireless, and in this case, it may be transmitted to the alarm device 100-1 or may be transmitted to the alarm devices 100-1 to 100-5. As this wireless communication protocol, a second wireless communication protocol (described later), which is a wireless communication protocol for linking the home alarms, may be used.

  The transfer control unit 202 performs control to transmit a batch AD conversion signal from the communication unit 204 to the temperature measurement chip 10 at predetermined intervals. That is, the temperature measurement chip 10 that has received this is caused to perform a temperature acquisition operation. Subsequently, the transfer control unit 202 sequentially transmits a polling signal designating an address of the temperature measurement chip 10, for example, a transmission source code that is an identifier assigned to each temperature measurement chip 10, and measures the temperature from each temperature measurement chip. Control to send a signal and receive it. Note that when the temperature measurement signal is voluntarily transmitted from the temperature measurement chip 10 at predetermined intervals, control for acquiring the temperature by the collective AD conversion signal or the polling signal is unnecessary.

  The transfer control unit 202 detects a temperature abnormality (overheating) when the temperature included in the temperature measurement signal is a threshold temperature Tth for detecting the temperature abnormality, for example, Tth = 65 ° C. or more. Then, a control is performed to output a temperature abnormality report signal from the report transmission unit 208 to the residence guard 100-1. The temperature abnormality may be detected when the temperature change rate is obtained from the temperature acquired over a plurality of times and the temperature change rate (rise rate) is equal to or higher than a predetermined change rate threshold value. In addition, the temperature abnormality may be detected by various calculations based on the temperature.

  In addition, the transfer control unit 202 outputs, for example, a state where the temperature obtained from the temperature measurement signal of the temperature measurement chip 10 is lower than the threshold temperature Tth = 65 ° C. for a predetermined time, for example, during the output of the temperature abnormality transfer signal. When the number of times continues, the recovery of the temperature abnormality is detected, and the recovery transmission signal is output from the transmission transmission unit 208 to the mortgage alarm device 100-1 via the transmission signal line.

  The transfer control unit 202 detects a temperature abnormality (overheating) when the temperature obtained from the temperature measurement signal is equal to or higher than the threshold temperature Tth = 65 ° C. and outputs a temperature abnormality transfer signal, and then is higher than the threshold temperature Tth. When a predetermined second threshold temperature Tth2, for example, Tth2 = 75 ° C. or higher, a second temperature abnormality (for example, risk of ignition) is detected, and the home guard is sent from the transmission transmitter 208 via the transmission signal line. For example, control may be performed so that the temperature abnormality emergency notification signal, which is a more urgent temperature abnormality notification signal, is output to the device 100-1 as the second temperature abnormality notification signal.

  The threshold temperature Tth is appropriately determined as necessary, but is set to a temperature exceeding the indoor maximum temperature. In this case, since the indoor maximum temperature varies depending on the season, for example, a different threshold temperature may be set according to the season. Also, when installing on equipment that uses fire, set the temperature to exceed the maximum temperature during normal use. On the other hand, it goes without saying that the threshold temperature is set to a temperature lower than the temperature at which a fire occurs (ignition temperature).

[Configuration of interlocked house alarm]
FIG. 5 is a block diagram showing a schematic configuration of the interlocking type house guard 100-1. In addition, although FIG. 4 takes the residence guard 100-1 as an example, the other residence guards 100-2 to 100-5 are the same.

  In FIG. 5, the home alarm device 100-1 includes an alarm control unit 102, an interlocking communication unit 104 connected with an antenna 106, a message receiving unit 108, a sensor unit 112, a notification unit 114, and an operation unit 116, and a battery (not shown). Operates with power supply.

  The alarm control unit 102 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 interlocking communication unit 104 receives an instruction from the alarm control unit 102 and transmits / receives an interlocking signal to / from the other residential alarm devices 100-2 to 100-5 according to a predetermined second wireless communication protocol. The interlocking signal is assigned as an identifier unique to each home guard 10, and is used as a code indicating the source when transmitting the signal, a group code indicating the interlocking group to which the self belongs, fire, etc. The format includes an event code indicating an event. The home guard 100-1 forms an interlocking group that transmits and receives signals according to the second wireless communication protocol with the home guards 100-2 to 100-5, and the group code is a code unique to this group. By using the group code, it is possible to prevent the interlocking signal from interfering with other adjacent groups.

  In the case of transmission / reception using the second wireless communication protocol in Japan, for example, STD-30 (a wireless equipment standard for a low-power security system wireless station) or STD known as a standard for a specific low-power wireless station in the 400 MHz band. -Conforms to T67 (standard for low-power radio station telemeter, telecontrol and data transmission radio equipment).

  The transfer receiving unit 108 is connected to the transfer adapter 200 through a transfer signal line, receives a temperature abnormality transfer signal, a recovery transfer signal, and the like, and outputs them to the alarm control unit 102.

  The sensor unit 112 detects smoke by, for example, a scattered light type smoke detection mechanism and outputs a detection signal (in this case, a smoke detection signal) corresponding to the smoke density. Based on this, the alarm control unit 102 detects a fire. Of course, another physical phenomenon may be detected by another element, and a fire may be detected based on this.

  The notification unit 114 includes, for example, a speaker, an LED, and respective drive circuits, and outputs an alarm sound from the speaker in accordance with an instruction from the alarm control unit 102 as needed, and displays an alarm with the LED. The operation unit 112 includes an alarm stop switch that receives an operation for stopping an alarm sound and / or an alarm display.

  The alarm control unit 102 detects the fire based on the smoke detection signal from its own sensor unit 112 or the fire interlocking signal received from another home alarm device, and the temperature abnormality from the transfer adapter 200. An alarm control function for detecting the reception of a transfer signal and providing an alarm is provided, and the following (A) and (B) are provided.

(A alarm control function based on self smoke detection or fire interlocking signal reception from other home alarm)
When the alarm control unit 102 detects a fire based on the smoke detection signal from the sensor unit 112, the alarm control unit 102 outputs a fire alarm sound indicating the interlock source from the notification unit 110 and performs a fire alarm display indicating the interlock source. In addition, the fire interlock signal which is an abnormal interlock signal is controlled to be transmitted from the interlock communication unit 104 to the other residential alarm devices 100-2 to 100-5, and the other residential alarm device which has effectively received the fire interlock signal. In 100-2 to 100-5, the fire alarm sound output and the alarm display indicating the interlock destination are performed.

  Moreover, the alarm control part 102 shows an interlocking | linkage destination from the alerting | reporting part 114, when the effective communication of the fire interlocking signal which one of the other residence alarm devices 100-2 to 100-5 transmitted by the interlocking communication part 104 is detected. Control is performed to output a fire alarm sound and display an alarm indicating the interlocking destination.

  In addition, when the alarm control unit 102 detects a fire recovery (fire detection state has been canceled) or an alarm stop operation during the output of the fire alarm, the alarm control unit 102 displays a fire alarm sound output and an alarm display indicating the link source from the notification unit 114. In addition to performing control to stop, control to transmit the fire recovery interlock signal or alarm stop interlock signal from the interlocking communication unit 104 to the other residential alarm devices 100-2 to 100-5, the fire recovery interlock signal or alarm stop The other alarm devices 100-2 to 100-5 that have effectively received the interlock signal stop the fire alarm sound output and alarm display indicating the interlock destination.

  In addition, the alarm control unit 102, when detecting the effective reception of the fire recovery interlock signal or the alarm stop interlock signal transmitted by any of the other residential alarm devices 100-2 to 100-5 by the interlock communication unit 104, the notification unit Control is performed to stop the fire alarm sound indicating the interlocking destination from 114 and to stop the alarm display indicating the interlocking destination.

  “Detecting effective reception of signal” means that the group code included in the received interlocking signal matches the group code registered in advance in its own memory as the receiving device and is recognized as the interlocking signal addressed to itself. Furthermore, it means that the signal content is recognized as having no abnormality. This also applies to signals transmitted to and received from the temperature measurement chip 10. (Regarding the temperature abnormality transfer signal or the like when received by the transfer receiving unit 108 via the transfer signal line, the verification of the group code can be omitted.) Sometimes called reception.

(B Alarm control function based on reception of temperature abnormality transfer signal from transfer adapter 200)
In addition, when the alarm control unit 102 detects the effective reception of the temperature abnormality transfer signal sent from the transfer adapter 200 via the transfer signal line and the transfer reception unit 108, the alarm control unit 102 detects the temperature indicating the link source from the notification unit 114. Control to output an abnormality (overheating) alarm. As an example of this temperature abnormality alarm, if a temperature abnormality is detected from the temperature of the temperature measuring chip 10-1 placed on the kitchen stove 12, "Please check that the kitchen stove is overheated." The voice message is repeatedly output from the speaker and the LED is turned on, for example.

  In other words, the temperature measurement signal sent from the temperature measurement chip 10 to the transfer adapter 200 includes a code (transmission source code) for specifying the temperature chip of the transmission source, and the home alarm device 100 from the transfer adapter 200. The temperature abnormality transmission signal sent to -1 includes that of the temperature chip that has transmitted the temperature measurement signal that is the source of the temperature abnormality detection. And the code | cord | chord which identifies each temperature chip | tip and the audio | voice message content of a temperature abnormality alarm are linked | related within the memory of the residence warning device 100-1. For this reason, the temperature chip in which the temperature abnormality has occurred as described above is recognized, and in response to this, the voice message of the temperature abnormality alarm can include, for example, the contents including the installation location.

  In addition, when the alarm control unit 102 notifies and outputs a temperature abnormality alarm from the notification unit 114, the alarm control unit 102 transmits a temperature abnormality interlocking signal according to the second wireless communication protocol from the interlocking communication unit 104 to the other residential alarm devices 100-2 to 100. Control to transmit to -5 is performed, and the temperature abnormality alarm indicating the interlocking destination is notified and output by the other residential alarm devices 100-2 to 100-5 that have effectively received the temperature abnormality interlocking signal.

  Further, the alarm control unit 102 effectively receives a recovery message indicating that the temperature abnormality of the temperature measuring chip has been recovered from the message adapter 200 via the message receiving unit 108 during the output of the temperature error alarm. Is detected, the temperature abnormality alarm output from the notification unit 114 is controlled to be stopped, and the recovery interlocking signal is transmitted from the interlocking communication unit 104 to the other residential alarm devices 100-2 to 100-5. Then, the other abnormal alarm devices 100-2 to 100-5 that have effectively received the recovery interlock signal stop the temperature abnormality alarm output indicating the interlock destination.

  The alarm control unit 102 sends a temperature abnormality emergency warning signal (second temperature abnormality message) based on detection of the risk of ignition (second temperature error) from the message adapter 200 via the message receiver 108.
