  The present invention relates to an alarm device with a test function, such as a so-called residence alarm device, which performs an alarm by detecting an abnormality such as a fire or a gas leak occurring in a monitoring area such as an office or a general house.

  Conventionally, an alarm device having a test function that is installed in a monitoring area such as an office or a general house and detects an abnormality such as a fire or a gas leak is known. In this type of alarm device, for example, it is installed in the kitchen, living room, bedroom, etc. of ordinary houses and operated alone, or the alarm devices installed in each room are connected to each other (multi-connection) and interlocked. It is like that. In the case of multi-connection, for example, when an alarm device is activated in the kitchen, the alarm signal of this alarm device is sent to the alarm device in the bedroom on the second floor, and the alarm device is activated to cause a fire or gas leak in the kitchen. Etc. can be known.

  In the alarm device with a test function, various test circuit portions are devised as shown in the following patent documents.

  (B) In the technique of Patent Document 2, the transmission / reception means for the alarm signal (that is, the transfer signal) for causing another alarm device to perform an alarm operation has not been tested, and the test result is normal. However, there is a risk that alarm signals will not be sent to other alarm devices during fire operation, or external alarm signals from other alarm devices may not be received. was there.

  (C) In the technique of Patent Document 3, in order to detect a user activity, a sensor different from the alarm target must be provided, and the configuration is complicated and the cost is high. Further, the test interval varies depending on the user's activity status, and there is a possibility that the worst test may not be performed in the case of an empty room. In particular, many fires are caused by arson, and it is necessary to operate the alarm normally even when no one lives. However, there is a disadvantage that the test is not performed when no one lives. .

(Operation)
FIG. 3 is a flowchart showing the monitoring operation of FIGS. 1 and 2.

(Normal monitoring operation: steps ST1 to ST8)
When DC drive power is supplied from the power supply control circuit 11 and the monitoring start switch or the like is operated in step ST1 to start the operation of the alarm 1, whether or not the switch 14a is turned on in step ST2. Is determined by the control unit 13. When the switch 14a remains off, the monitoring operation by the control unit 13 is started in accordance with the program stored in the ROM in the memory 17, and the detection circuit 18 is synchronized with the clock signal supplied from the clock oscillation circuit 16. By the drive control, detection processing (sampling processing) of the fire detection sensor 19 and the gas detection sensor 20 is performed at a predetermined cycle (for example, every several seconds). In step ST3, when a fire or a gas leak occurs, the fire detection sensor 19 or the gas detection sensor 20 detects it, and when the detected value is input to the detection processing means in the control unit 13, the process proceeds to step ST4. move on.

  In step ST <b> 4, the detection value of the fire detection sensor 19 or the gas detection sensor 20 is compared with the threshold value stored in the ROM in the memory 17 by the detection processing means in the control unit 13. When the detected value is smaller than the threshold value, the process returns to step ST3. When the detected value is larger, an alarm signal is output from the detection processing means in the control unit 13, and the process proceeds to the alarm process of step ST5.

  In the alarm processing of step ST5, when the alarm signal output from the detection processing means in the control unit 13 is input to the alarm processing means in the control unit 13, information on the alarm signal (fire occurrence information and gas leak information) ) Is processed, the acoustic circuit 21 and the display circuit 23 are operated, an alarm sound from the buzzer in the acoustic device 22, a voice message from the speaker, and the like, or a lamp in the display 24 is turned on or blinking, or An alarm message is displayed on the display screen. When the alarm signal output from the detection processing means in the control unit 13 is input to the transmission / reception processing means in the control unit 13, an address and alarm information are added to the alarm signal, It is sent to another alarm device 1 via the line 2 (for example, sent from the alarm device 1-1 to 1-3), and a predetermined interlocking alarm process is performed in the other alarm device 1-3. In the linked alarm processing in the other alarm devices 1-3, an alarm signal to which an address and alarm information are added is received by the transmission / reception circuit (25), and the content of the alarm signal is transmitted / received in the control unit (13). The alarm processing means, the acoustic circuit (21), and the display circuit (23) in the control unit (13) notify the interlocking alarm from the acoustic device (22) and the display (24).

  After the alarm output is started in step ST5, it is determined in step ST6 whether or not the switch 14a has been operated to the on state. When the switch 14a is turned on after the alarm output is started, the input current of the switch 14a flows to the resistor 14c, and the thyristor 14b is turned on. Then, even if the switch 14a self-returns to the OFF state, the ON state of the thyristor 14b is self-maintained, and the switch input current is supplied to the control unit 13 through the thyristor 14b. In step ST7, an alarm stop command is output from the alarm processing means in the control unit 13, and the operations of the display circuit 23 and the display 24 are continued. However, only the operation of the acoustic circuit 21 is stopped and the acoustic device 22 is stopped. Only the voice alarm from stops. The alarm stop command output from the alarm processing means in the control unit 13 is added with an address or the like by the transmission / reception processing means in the control unit 13 and is sent to the interlocking lead wire 2 via the transmission / reception circuit 25 to receive other alarms. Sent to vessel 1.

  After stopping the alarm in step ST7, the process proceeds to step ST8, where it is determined whether or not a predetermined time (for example, several minutes) has elapsed by a clock function (or timer 26) provided in the control unit 13, and the predetermined time has elapsed. If so, the process returns to step ST2 via the connector 2, and the monitoring process is resumed.

(Manual test operation: steps ST9 to ST10)
In step ST2, when the switch 14a is turned on, the process proceeds to step ST9, where a manual alarm test is performed. That is, when the switch 14a is operated to the on state and then the contact of the switch 14a is self-returned to the off state, the output pulse current of the switch 14a is supplied to the control unit 13, and the test controlled by the control unit 13 A function test is performed in the circuit 27. In the functional test, for example, a test signal (a signal similar to the detection signal of the fire detection sensor 19 or the gas detection sensor 20) is generated by the test circuit 27, and whether or not a fire or a gas leak has occurred is generated based on the test signal. This is determined by the detection processing means in the control unit 13.

  In step ST1, when it is determined that a fire or gas leak has occurred, a test alarm signal is output from the detection processing means in the control unit 13 to indicate that the operation can be normally performed, and the control is performed. The test result is sent to the alarm processing means in the unit 13, and the test result is notified from the acoustic device 22 by the acoustic circuit 21 or from the display 24 by the display circuit 23. At this time, the operation detection unit 28 detects whether or not the detection circuit 18, the acoustic device 22, the display 24, and the transmission / reception circuit 25 are operating normally. When the detection result is normal, the process returns to step ST2 via the connector 1, and when the detection result is abnormal, that is, when the alarm device 1 is out of order, that fact is notified from the display 24 or the like, and the monitoring operation is performed. finish.

(Repetitive cycle operation by timer: steps ST11 to ST12)
In step ST2, when the switch 14a is turned on, the above test operation is performed in step ST9, and the process proceeds to step ST11 to start the counting operation of the timer 26. The timer 26 is set in advance with a repetition period (for example, 24 hours (1 day) or a multiple of 24 hours (day, week, month, year)) and a fixed time (for example, 7:10) within each period. Thus, in step ST12, the control unit 13 determines whether or not the timer set time has come. When the timer set time has arrived, the process proceeds to step ST9 and the same test operation as described above is performed.

(effect)
The first embodiment has the following effects (1) to (3).

  (1) The timer 26 can arbitrarily set a time at which the user performs a periodic automatic test, so that the alarm device 1 can be automatically tested at a date and time convenient for the user. In addition, since the test result by sound is notified (sounded) from the acoustic device 22 at the same time such as every day or every week, it can be used on a daily basis instead of an alarm clock or the like.

  (2) Since the operation detection unit 28 is provided, the detection circuit 18, the acoustic device 22, the display 24, and the transmission / reception circuit 25 function reliably when an alarm is generated during a manual test and an automatic periodic test using the timer 26. Can be detected. In addition, if the detection result of the operation detection unit 28 is displayed on the display 24, the detection result can be known later even if the user is not at the time of the test.

  (3) Since the switch 14a is used not only for the timer start but also for the alarm sound stop and the manual test start, the number of switches can be reduced by sharing the switches, and the cost can be reduced by simplifying the configuration.

  The present invention is not limited to the first embodiment, and various modifications can be made. As a second embodiment which is this modification, for example, there are the following (A) to (H).

  (A) The timer 26 may be omitted, and a timer means for counting time based on the clock signal output from the clock oscillation circuit 16 may be provided in the control unit 13. By omitting the timer 26, the circuit configuration can be simplified.

  (B) In the timer 26 (or the time measuring means in the control unit 13 of (A) corresponding to this), the repetition period can be set to a value of 24 hours or a multiple of 24 hours. A configuration in which a plurality of repetition cycles can be set, and stop means (for example, using the switch 14a or a new stop switch) for stopping the output of a time signal based on a short cycle may be provided. When setting a plurality of repetition cycles, for example, two timers (or two timing means in the control unit 13 corresponding thereto) are provided, and the shorter cycle is 24 hours and the longer cycle is 30 days (24 hours). X 30 times), so that 24 hours can be used as an alarm clock. Also, if an alarm clock is not required, the shorter period of 24 hours is stopped by the stopping means, but the longer period of 30 days is operating, so the test is always performed once every 30 days. It is possible to confirm whether or not the performance of the alarm device 1 can be maintained, and it is easy to use.

  (C) The content of the alarm by the audio equipment 22 or the display device 24 may be different between a normal alarm and a test. For example, at the time of the test, the sound device 22 changes the ringing pattern and volume of the buzzer different from the normal one, or reproduces a different voice message. Thereby, this alarm and a test alarm can be distinguished and it can prevent acting wrongly with this alarm at the time of a test alarm.

  (D) When testing an alarm device (for example, 1-1), a test alarm signal is transferred from the transmission / reception circuit 25 to another alarm device (for example, 1-2...) Via the interlocking lead wire 2. When the operation detector 28 detects whether the transmission / reception circuit 25 operates normally, the other alarm devices 1-2,... It may be configured such that when an alarm signal is received, an alarm is not generated, and an alarm is issued only when a continuous normal alarm signal is received. With such a configuration, it is possible to prevent a mistaken action from this alarm during the test.

  (E) Although a plurality of alarm devices 1-1 to 1-N are multi-connected by the interlocking lead wire 2, they may be multi-connected by radio such as radio waves or infrared rays. At this time, the configuration of the transmission / reception circuit 25 may be changed accordingly.

  (F) The test circuit 27 may be omitted, and an external test signal output test device provided outside may be connected to the transmission / reception circuit 25 and the function test of the alarm device 1 may be performed instead. Thereby, the structure of the alarm device 1 can be simplified and the cost can be reduced.

  (G) Although the circuit configuration is such that the energized state of the switch 14a is self-holding using the thyristor 14b, the self-holding circuit may be configured using other self-holding elements such as a latching relay or other electronic components. .

  (H) The alarm device 1 (1-1 to 1-N) can be used alone without being multi-connected. If a single-dedicated structure is used from the beginning, the transmission / reception circuit 25 and the like can be omitted, thereby simplifying the configuration and reducing the cost.

The alarm device according to appendix 6 is the alarm device according to any one of appendices 2 to 5, in which the alarm means is configured to continuously output the external test signal sent from the outside. Only the alarm is issued.

  According to the alarm devices described in Appendices 1 to 4, a single switch can be used to start a periodic test timing means, start a manual test, or stop an alarm sound. Simplification of configuration and cost reduction are possible. Since the period and time of the periodic test timing means can be set arbitrarily, the periodic test alarm can be generated at a time convenient for the user, which does not bother the user and can be used as an alarm clock. Furthermore, since the test means and the operation detection means are provided, it can be tested that it functions reliably when an alarm is generated.

  According to the alarm devices described in appendices 5 and 6, when a test operation is performed, it can be prevented from being mistaken for this alarm.
