Ventilation holes 1a and 1b for taking in outside air are formed on the front and upper right side surfaces of the main body case 1. A gas sensor 11 is arranged in the vicinity of the ventilation hole 1a, and a CO sensor 12 is arranged in the vicinity of the ventilation hole 1b. Has been. In addition, a sound emitting hole 1c is formed in the lower left front surface of the main body case 1, and a speaker 18a is disposed in the vicinity of the sound emitting hole 1c. An operation part 1d of the inspection stop switch 13 is provided at the lower front part of the main body case 1, and this operation part 1d is marked "alarm stop". Further, a display window 1e for each of the LEDs 16a, 16b, and 16c and a display window 1f for the LCD display 17a are provided on the right side of the front surface of the main body case 1, and "information" is displayed next to the display window 1e corresponding to the LED 16a.

  The power switch 20 for turning on the power by the battery 20 a is housed in the main body case 1 and hidden behind the main body case 1 by “fitting out”. The power switch 20 is turned off by the power switch 20 from shipment to installation, and the power switch 20 is turned on by a contractor or the like at the time of installation.

  Next, the operation and processing of the embodiment under the control of the control unit 10 having the above-described configuration will be described. The gas alarm device 100 of this embodiment performs operations of “automatic initial inspection process”, “inspection mode process”, and “inspection switch process”. In the following description, “battery voltage check” indicates that the input of the battery voltage input circuit 14 is inspected, and “PC communication input check” indicates that the input of the communication interface unit 19 is inspected. “LED” indicates the LEDs 16a, 16b, and 16c, and “speaker audio circuit check” indicates that the speaker 18a and the audio output circuit 18 are inspected.

(Automatic initial inspection process) The automatic initial inspection process is started by energization from the battery 20a when the power switch 20 is turned on. Then, when the power is turned on by the power switch 20, a battery voltage check start-up display is performed and a start-up sound is sounded. After that, an inspection operation is started and a failure diagnosis of various device elements such as the gas sensor 11 and the CO sensor 12 is performed. In this case, the inspection stop switch 13 can be restarted by an operation of “long press”.

  FIG. 3 is a timing chart showing an example of the operation during the automatic initial inspection process. First, a circuit voltage check for 100 ms and a PC communication input check for 100 ms are performed (a.). After the power supply is stabilized at 200 ms, the clock timer is started. Also, the initial value is read from the EEPROM 15 (data flash) while waiting for 1 second when the subclock transmission is stabilized, and checked (b.). Then, after waiting for 1 second when the sub clock transmission is stabilized, the battery voltage check (c.) By the pseudo load and the speaker sound circuit check (d.) Are performed, and the LEDs 16a, 16b, and 16c are all turned on (f. To h). .) The battery voltage check prevents repeated operations when the battery is exhausted by applying a pseudo load prior to the lighting of the LED and the sound. While all the LEDs are lit, the speaker 18a is disconnected and the audio output circuit 18 is checked by ringing the start sound “pi” (e.).

  Next, in order to indicate that the automatic initial inspection process is being performed, the green LED 16a starts blinking at 2 Hz (f.). This blinking continues for 30 seconds, during which time the gas sensor 11 and the CO sensor 12 start driving for stabilization every second (j.). Then, while the gas sensor is waiting for stabilization for 37 seconds, a failure check is performed by the gas sensor drive circuit and the CO sensor base voltage (i.).

  When the automatic initial inspection process ends for 30 seconds, the cause of ringing is displayed (f. To h.). After the ringing cause display is finished, various check results are sounded as follows. "Normal" at normal end, "Beep, failure, please contact the dealer" when failure is detected, "Pi, battery is dead, please contact the dealer" when battery voltage is low When the expiration date has passed, a sound is sounded, “The expiration date has expired, please contact the dealer”. Then, after the sounding is finished, the operation of “inspection mode processing” is performed for 3 minutes and 30 seconds.

(Inspection mode processing) In the inspection mode processing after the automatic initial inspection processing started when the power is turned on, hydrogen gas and CO gas previously collected from the combustion exhaust gas are used to perform gas CO alarm inspection. During this inspection mode, the “alarm start time” and “alarm release time” are shortened for the purpose of improving the inspection performance. In the gas alarm, after the high concentration alarm, the standby state (alarm release) is set according to the low concentration alarm state. Also, a methane alarm is generated by detecting hydrogen gas. In the CO alarm, the alarm is canceled when a specific gas concentration changes. Moreover, LED display delay time and low concentration ringing delay time are not provided. The alarm can be stopped by operating the inspection stop switch 13.

(Inspection switch processing) The inspection switch processing is started by operating the inspection stop switch 13 in a normal monitoring state. This operation is performed when the inspection stop switch 13 is pressed for less than 3 seconds (hereinafter referred to as “short press”) and when the inspection stop switch 13 is pressed for 3 seconds or more and less than 6 seconds (hereinafter, referred to as “short press”). The processing operation is changed depending on whether the inspection stop switch 13 is pressed for 6 seconds or longer (hereinafter referred to as “long press”). Then, an automatic initial inspection process that simplifies the automatic initial inspection process that starts when the power is turned on is performed during a long pressing operation.

FIG. 4A shows a case where there is no ringing history, and FIG. 4B shows a case where there is a ringing history. The difference between the two is the manner of ringing cause display. First, when the inspection stop switch 13 is turned on (a.), The speaker sound circuit check (b.) Is performed and the start-up sound “pi” is sounded (c.). When the on operation of the inspection stop switch 13 is completed within 3 seconds, the LEDs 16a, 16b, and 16c are all turned on (d. To f.) To display the cause of ringing. When the ringing cause display is completed, the speaker audio circuit check (b.) Is performed, and the “normal” audio ringing (c.) Is performed.

  Here, the alarm state finally determined is stored in the EEPROM 15, and if the time value (date and time) at the time of the final alarm determination is not within 10 days (240 hours) from the present time, it is assumed that there is no ringing history. The operation 4 (A) is performed. Further, if it is within 10 days (240 hours) from the present time, it is considered that there is a ringing history, and the operation of FIG. That is, in the ringing cause display, in the case of FIG. 4A, the LEDs 16a, 16b, and 16c are lit for 0.5 seconds.

Is performed, and the red LED 16c continues to flash (e.) For 1 second period for 7.5 seconds. And a gas alarm sound is sounded during this 7.5 second blink (c.). When the blinking of the red LED 16c for 7.5 seconds is completed, the speaker sound circuit check (b.) Is performed, and the blinking (f.) Of the yellow LED 16b in a 1-second cycle is continued for 7.5 seconds. Then, during this 7.5 second blink, a CO alarm sound is generated (c.). Then, when the blinking of the yellow LED 16b for 7.5 seconds is completed, the ringing (c.) Of “pi” is performed after 1 second.
