Description

  The present invention relates to various alarm devices such as a fire alarm device, a gas leak alarm device, and a fire gas leak alarm device.

  Conventionally, gas meters, gas leak alarms, etc. have been installed in homes, and the amount of gas used and the presence or absence of gas leaks that have been grasped by them are conventionally known only for each device in a stand-alone manner. However, with the spread of centralized monitoring at remote locations, the number of cases where individual wired connections were started to centralized monitoring panels connected to remote centralized monitoring points via telephone lines and the like was increasing.

  In recent years, as disclosed in Japanese Patent Laid-Open No. 6-85938, in order to improve the degree of freedom of installation location, a gas leak alarm device, a gas meter, and the like are wirelessly connected to a centralized monitoring panel via a wireless device. A configuration has been proposed.

In recent years, it has become mandatory to install fire alarms in newly constructed units due to amendments to laws and regulations, and alarms detected by these fire alarms are generally notified to the outside by voice or display. In this case, since it can be recognized only at the place where the alarm condition has occurred, there are those that install multiple fire alarms, connect the interlock connectors of each fire alarm device with wires, and link them together. is there. Furthermore, this is not only a problem in one house, but also an important problem in expecting a quick response to an alarm state or failure state for residents in neighboring houses. There is a demand for a measure for promptly notifying where the state has occurred in places other than the place where the state has occurred.

The battery Ba is connected to the booster circuit 24 via the connector 23 and disposed in the main body case 1. Further, although not shown, a serial interface circuit for performing serial communication with a personal computer for setting at the time of factory shipment is also provided.

  An outline operation by the control of the CPU 11 of the fire alarm 10 will be described. The CPU 11 monitors the fire sensor 12, and when the fire sensor 12 detects smoke in the event of a fire, the CPU 11 controls the display circuit 16 to flash the red alarm lamp 4 and drive the audio output circuit 17 to alarm. A fire alarm is issued with a buzzer sound and voice by the speaker 6. Further, when an interlocking alarm is instructed from the wireless unit 30 via the interlocking connector 20 on the back surface of the main body case 1, the red alarm lamp 4 blinks and an alarm with a buzzer sound and sound is emitted. Further, upon receiving an alarm stop instruction from the wireless unit 30, the red alarm lamp 4 is turned off and the buzzer sound and sound are stopped. Further, the CPU 11 monitors the outputs of the fire sensor failure monitoring circuit 13, the booster circuit failure monitoring circuit 14, the power supply voltage drop monitoring circuit 15, and the speaker disconnection monitoring circuit 18, and when an abnormality is detected in each monitoring circuit. The abnormal contents of each function are notified by blinking of the green alarm lamp 5, a buzzer sound and a voice alarm. Further, when the inspection switch 21 is turned on by pushing the push button 3 or pulling the inspection string 7, the apparatus is inspected and the abnormal content of the function is confirmed. Further, as will be described later, when the inspection switch 21 is turned on during an interlocking alarm, the alarm sound is stopped.

  As shown in FIG. 2, the wireless unit 30 includes a CPU 31, a ROM 32, a RAM 33, a communication interface 34, and a connector interface 35. The CPU 31 controls the wireless unit 30 using the work area of the RAM 33 by the control program stored in the ROM 32. At the time of control, the CPU 31 obtains the functions of a 3-minute timer, a fixed-time timer, and a 4-minute timer using the counter register of the RAM 33 and the like. In addition, the RAM 33 stores a flag storage area for storing various states, an alarm message to be output to the outside as interlocking instruction information and release instruction information, a message configuration area for configuring a release message, and reception for temporarily storing received messages. A buffer is set.

  4 to 10 are flowcharts relating to the processing of the first embodiment. FIGS. 4, 9 and 10 are main part flowcharts of the control program of the CPU 11 in the fire alarm 10, and FIGS. 5 to 8 are wireless units. 3 is a main part flowchart of a control program of a CPU 31 in FIG. 5 is a flowchart of the first timer interrupt process, FIG. 6 is a flowchart of the state change process, FIG. 7 is a flowchart of the interrupt process activated by the 3-minute timer, and FIG. 8 is a flowchart of the second timer interrupt process. 9 is a flowchart of a subroutine that is activated when the inspection switch 21 is turned on by operating the inspection string 7, and FIG. 10 is a flowchart of an interrupt process that is activated by a timer for a predetermined time. The interrupt processing in FIGS. 7 and 10 is started each time the timers corresponding to the 3-minute timer and the fixed-time timer are up.

  The flow of these processes varies depending on the current operation mode, but the operation mode (current state) is any one of “normal”, “alarming”, “interlocking alarming”, and “next door alarming”. “Normal” means that no fire has been detected (sometimes immediately after a fire is detected), “Alarming” means that the fire sensor is sounding after a fire has been detected (sound notification), “Linked alarm” “Medium” is the state that is sounding in conjunction with the fire detection of another fire alarm device, and “Neighborhood alarming” is the state that is sounding in conjunction with the fire detection of the fire alarm device of the adjacent house.

  The “stop flag” is set when the inspection switch 21 is turned on by pulling the inspection string 7 during the alarm, and the initial value is a clear state. Note that the inspection switch 21 is also turned on by operating the push button 3, but in the following description, an operation of pulling the inspection string 7 will be described as an example.

  Moreover, the message | telegram sent / received between other fire alarm apparatuses via the wireless unit 30 is as follows. The telegram sent and received between the house fire alarm device as the interlocking instruction information is house fire + house code + district code + device information. The message exchanged with the fire alarm device of the neighboring house as the interlocking instruction information is the neighbor fire + house code + district code + device information. A message exchanged with the fire alarm device in the house as release instruction information is release + house code + district code + device information. The message exchanged with the fire alarm device of the neighbor as release instruction information is neighbor release + house code + district code + device information. “House code” is a code that distinguishes houses from home and neighbors, “District code” is a code that identifies the area where the house is located, and “Equipment information” is a fire alarm device, security alarm, etc. These are codes that distinguish the types, and these codes have contents corresponding to the alarm device that transmits the message.

  On the fire alarm 10 side, the state of the fire sensor 12 is determined in step S1 of FIG. 4, and if a fire is detected, a fire alarm is started in step S2, and an alarm signal is sent from the interlocking connector 20 to the wireless unit 30 in step S3. Output to. In step S10, other various processes are performed, and the process returns to step S1. On the other hand, if no fire is detected in step S1, the alarm is stopped in step S4. Next, in step S5, it is determined whether an interlock instruction signal is input from the interlock connector 20. If there is no input, the process proceeds to step S7. If the interlock instruction signal is input, an interlock alarm is started in step S6, and the process proceeds to step S7. Then, a check string process (FIG. 9) described later is performed in step S7, and the process proceeds to step S8. In step S8, it is determined whether an interlock stop signal is input from the interlock connector 20. If there is no input, the process proceeds to step S10. If an interlock stop signal is input, the ringing is stopped in step S9, and the process proceeds to step S10. In step S10, other various processes are performed, and the process returns to step S1. Through the above processing, the fire alarm 10 itself performs a normal operation, performs alarm notification by fire detection, and outputs an alarm signal. Also, when an interlock instruction signal is input, an interlock alarm is performed.

  On the other hand, on the wireless unit 30 side, the timer interrupt process of FIGS. 5 and 8 is repeated at a predetermined timing (for example, at intervals of several milliseconds). FIG. 5 is a process for monitoring the state of the fire sensor 12 by a timer interruption process of several milliseconds. In step T1, it is determined whether the fire sensor 12 has changed from the previous state. If there is no change, the process returns to the original routine. If there is a change, the state change process of FIG. 6 is performed in step T2. In the state change process of FIG. 6, the state of the fire sensor 12 is determined in step S11, and if the fire is extinguished, the process proceeds to step S16, and if it is a fire state, the operation mode is set to “alarming” in step S12. A home fire telegram is transmitted in S13, a neighbor fire telegram is transmitted in step S14, a 3-minute timer is started in step S15, and the original routine is restored.

  If the fire is extinguished in step S11, the operation mode is set to “normal” in step S16, and the interlocking stop signal is output to the fire alarm device 10 in step S17 to stop ringing. Next, a cancellation message is transmitted in step S18, a neighbor cancellation message is transmitted in step S19, and the 3-minute timer is stopped in step S20. In step S21, the timer is stopped for a predetermined time. In step S22, the stop flag is cleared and the process returns to the original routine.

  In the 3-minute timer interrupt process of FIG. 7, a home fire telegram is transmitted in step S23, a neighbor fire telegram is transmitted in step S24, and the 3-minute timer is restarted in step S25 to return to the original routine.

  In the interrupt processing of FIG. 8, wireless reception is monitored in step S26, and if there is reception, it is determined in step S27 whether the operation mode is “alarming”, and if it is “alarming”, the process returns to the original routine. If not "alarming", it is determined in step S28 whether the house codes match. If the house codes do not match, the process proceeds to step S38. If the house codes match, it is determined in step S29 whether a home fire telegram has been received. If no home fire message has been received, the process proceeds to step S33. If a home fire message has been received, it is determined in step S30 whether the stop flag is “clear”. If the stop flag is not “clear”, the process returns to the original routine. If the stop flag is “clear”, an interlocking command signal is output from the interlocking connector 20 (to the fire alarm device 10) in step S31 to interlock the fire alarm. To start. In step S32, the operation mode is set to “interlocking alarming”, and the process returns to the original routine. If no home fire message has been received in step S29, it is determined in step S33 whether a release message has been received. If no release message is received, the process returns to the original routine. If a release message is received, an interlock stop signal is output from the interlock connector 20 (to the fire alarm device 10) in step S34 to stop ringing. Next, the operation mode is set to “normal” in step S35, the timer is stopped for a predetermined time in step S36, the stop flag is cleared in step S37, and the original routine is restored.

  If the house code does not match in step S28, it is determined in step S38 whether the district code matches. If the district code does not match, the process returns to the original routine. If the district codes match, it is determined in step S39 whether a neighbor fire message has been received. If no neighbor fire message has been received, the process proceeds to step S43. If a neighbor fire message has been received, a stop flag is set in step S40. It is determined whether it is “clear”. If the stop flag is not “clear”, the process returns to the original routine. If the stop flag is “clear”, an interlock command signal is output from the interlock connector 20 in step S41 to start a neighbor fire alarm. In step S42, the operation mode is set to “Neighbor alarm” and the process returns to the original routine. If no neighbor fire message is received in step S39, it is determined in step S43 whether a neighbor release message is received. If the neighbor release message is not received, the process returns to the original routine. If the neighbor release message is received, the interlock stop signal is output from the interlock connector 20 in step S44 to stop ringing. Next, the operation mode is set to “normal” in step S45, the stop flag is cleared in step S46, and the process returns to the original routine.

  In the check string processing of FIG. 9, it is determined in step S47 whether the check switch 12 is on. If not, the process returns to the original routine. If so, the operation mode is not “normal” in step S48. If it is “normal”, the process returns to the original routine. If it is not “normal”, the stop flag is set in step S49, and the ringing is stopped in step S50. Then, in step S51, it is determined whether the operation mode is “next door alarm is in progress”. If “next door alarm is in progress”, the process returns to the original routine as it is. Start the timer and return to the original routine.

  In the fixed time timer processing of FIG. 10, the stop flag is cleared in step S53, and it is determined whether the operation mode is “alarming” in step S54. If not “alarming”, the process proceeds to step S56. If “alarming”, a fire alarm is started in step S55, and the process returns to the original routine. . If the operation mode is not “alarming”, it is determined in step S56 whether the operation mode is “interactive alarming”. If not “interactive alarming”, the process returns to the original routine. If there is, the linked fire alarm is started in step S57 and the process returns to the original routine.

  With the above processing, when an alarm is issued in the house, by pulling the check string 7, the ringing of the fire alarm device that pulled the check string 7 can be stopped, and if the fire continues, It rings again after a certain period of time (recovery time). Thereby, in the case of a false alarm, the alarm can be stopped immediately. Further, in the next house, similarly, by pulling the inspection string 7, the ringing of the fire alarm device that has pulled the inspection string 7 can be stopped, but the timer is started for a certain time because it does not pass through step S52 of FIG. Therefore, the stop flag is not cleared (S53). Therefore, even if the neighbor fire telegram is received again (from the neighbor), the process returns to the original routine from S40 in FIG. 8, and thus does not ring again. Therefore, it is convenient when there is a misinformation.

  FIG.11 and FIG.12 is a figure which shows notionally the example of operation | movement by the fire alarm apparatus of 1st Embodiment. In the operation example of FIG. 11, in the fire alarm device of A of A house, when the fire alarm detects a fire (fire source), an alarm is issued and an alarm signal (alarm signal output via the interlock connector 20) is wirelessly transmitted. The wireless unit transmits the home fire telegram to the other fire alarm devices B and C of the home A. In addition, the adjacent house fire telegram is transmitted to the fire alarm devices of A, B, and C of B house. Each fire alarm device outputs an interlock instruction signal from the wireless unit to the fire alarm device, and issues an interlock alarm. When the alarm is stopped with the check string 7 in the fire alarm device at B in the house A, the alarm does not sound even when the next in-house fire telegram is received, but it sounds again after a certain time as the return time. On the other hand, if the alarm is stopped with the check string 7 in the fire alarm device of A at B home, it remains as it is.

  Fig. 12 shows an example of operation when the fire is extinguished. A fire is detected by the A fire alarm device at A's house, and B, the fire alarm device at B, and the A, B, C fire alarm devices at B's home are linked to each other. Suppose that When fire extinguishing is detected by the fire alarm device of A in A's house, an unlocking message and a neighbor release message are transmitted. The B and C fire alarm devices at A's house are stopped by a release message, and the A, B, and C fire alarm devices at B's house are stopped by a neighbor release message. When stopped by this cancellation message and neighbor release message, when a new house fire or neighbor fire is received, an interlocking alarm is issued as usual.

  FIGS. 13 to 16 are flowcharts relating to the processing of the second embodiment, FIGS. 13 to 15 are main part flowcharts of the control program of the CPU 31 in the wireless unit 30, and FIG. 16 is the control program of the CPU 11 in the fire alarm 10 It is a principal part flowchart. In the second embodiment, it is the same that the CPU 11 in the fire alarm 10 performs the processing of FIG. 13 is a flowchart of the first timer interrupt process, FIG. 14 is a flowchart of an interrupt process started by a 3-minute timer, FIG. 15 is a flowchart of the second timer interrupt process, and FIG. It is a flowchart of the subroutine started when the switch 21 is turned on. Further, the interrupt process of FIG. 14 is started every time the 3-minute timer expires.

  In step S61 in FIG. 13 on the wireless unit 30 side, the state of the fire sensor 12 is determined based on whether or not an alarm signal is input from the fire alarm device 10 via the interlocking connector 20, and if the fire is extinguished, step S61 is performed. Proceeding to S66, if it is a fire condition, the operation mode is set to “alarming” in step S62, a home fire message is transmitted in step S63, a neighbor fire message is transmitted in step S64, and a 3-minute timer is set in step S65. Start and return to the original routine.

  If the fire is extinguished in step S61, the operation mode is set to “normal” in step S66, and the interlock stop signal is output to the fire alarm device 10 in step S67 to stop ringing. Next, a cancellation message is transmitted in step S68, a neighbor cancellation message is transmitted in step S69, the 3-minute timer is stopped in step S70, and the original routine is restored.

  In the 3-minute timer interrupt process of FIG. 14, a fire alarm is started in step S71, a home fire message is transmitted in step S72, a neighbor fire message is transmitted in step S74, and the 3-minute timer is restarted in step S75. Return to the original routine.

  In the interrupt processing of FIG. 15, wireless reception is monitored in step S75, and if there is reception, it is determined in step S76 whether the operation mode is “alarming”, and if it is “alarming”, the process returns to the original routine. If not "alarming", it is determined in step S77 whether the house codes match. If the house codes do not match, the process proceeds to step S84. If the house codes match, it is determined in step S78 whether a home fire telegram has been received. If no home fire telegram is received, the process proceeds to step S81. If a home fire telegram is received, the interlock command signal is output from the interlock connector 20 in step S79 to start the interlock fire alarm. In step S80, the operation mode is set to “interlocking alarming”, and the process returns to the original routine. If no home fire message has been received in step S78, it is determined in step S81 whether a release message has been received. If no release message has been received, the routine returns to the original routine. If a release message has been received, the interlock stop signal is output from the interlock connector 20 in step S82 to stop ringing, and the operation mode is set to “normal” in step S83. To return to the original routine.

  If the house code does not match in step S77, it is determined in step S84 whether the district code matches. If the district code does not match, the process returns to the original routine. If the district codes match, it is determined in step S85 whether a neighbor fire message has been received. If no neighbor fire message has been received, the process proceeds to step S88. If a neighbor fire message has been received, the interlock connector 20 is checked in step S86. Outputs an interlocking command signal and starts a neighbor fire alarm. In step S87, the operation mode is set to "Neighbor alarm" and the process returns to the original routine. If no neighbor fire message is received in step S85, it is determined in step S88 whether a neighbor release message is received. If the neighbor release message has not been received, the process returns to the original routine. If the neighbor release message has been received, an interlock stop signal is output from the interlock connector 20 in step S89 to stop ringing. In step S90, the operation mode is set to “normal” and the process returns to the original routine.

  In the check string process of FIG. 16, it is determined in step S91 whether the check switch 12 is on. If it is not on, the process returns to the original routine. If it is on, the operation mode is not “normal” in step S92. If it is “normal”, the process returns to the original routine. If it is not “normal”, the ringing is stopped in step S93, a cancel message is transmitted in step S94, and a neighbor cancel message is transmitted in step S95. Return to the original routine.

  With the above processing, if an alarm is issued at home, the alarm string other than the fire source can be stopped by pulling the check string 7, and if the fire continues, the alarm message Rings again after receiving. In the first embodiment, since only the fire alarm device with the inspection string pulled is not stopped, it is necessary to pull the inspection strings of all the alarm devices if a plurality of units have issued an alarm. This second embodiment Then, it can be stopped by operating only one fire alarm device. Thereby, in the case of a false alarm, the alarm can be stopped immediately. In addition, since other than the fire source is stopped, the fire source can be specified. Further, by pulling the inspection string, it is possible to stop the alarm of the neighboring house whose house code matches.

  17 and 18 are diagrams conceptually showing an example of operation by the fire alarm device of the second embodiment. In the operation example of FIG. 17, in the fire alarm device of A of A house, when the fire alarm detects a fire (fire source), an alarm is issued, and this wireless unit transmits a home fire message and a neighbor fire message, and A Fire alarms at B and C at home, and fire alarm devices at A, B, and C at home B each issue an interlocking alarm. When the alarm is stopped with the check string 7 in the fire alarm device at B in the house A, a cancel message and a neighbor cancel message are transmitted, and the sound of the fire alarm device other than the fire source stops. And the fire alarm device of B and C of A house and the fire alarm device of A, B, and C of B house issue a linked alarm by the next home fire message and the neighbor house fire message.

  FIG. 18 is an example of operation when the inspection string is pulled at the house B other than the fire source. The fire alarm device at the house A, the fire alarm device at the house B, and the house A at the house B , B, C fire alarm devices are issuing interlocking alarms. When the inspection string is pulled by the fire alarm device at A in B house, the fire alarm devices at B and C in B house are stopped by the release message, but in the fire alarm device at A house, the neighbor release message from the neighbor is Ignore it and the interlocking alarm will continue. And if fire extinguishing is detected by A fire alarm device of A home, the fire alarm device of B, C of A home, and the fire alarm device of A, B, C of B home by unlocking message and neighbor release telegram Are stopped.

  In the above embodiment, the fire alarm device is configured by connecting the wireless unit 30 to the interlock connector 20 of the fire alarm device 10, but the processing of the fire alarm device 10 and the processing of the wireless unit 30 are performed by one CPU. It may be an integrated alarm device to be controlled.
