Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to an abnormality detection system for a gas leak alarm, for example.

[0002]

[Prior art]

 Since gas alarms, temperature sensors, and optical sensors are used as monitoring devices for disaster alarms that warn of fires and gas leaks, the sensor unit is normally kept in the energized state. For this reason, various means have been considered to notify the alarm of the alarm so that failure due to aged deterioration of the sensor unit and abnormality in power supply to the alarm from the commercial power source are not left. For example, turning off the power lamp, flashing the strobe lamp, buzzer sound, warning voice, and warning text display.

A gas leak alarm will be described as an example with reference to FIG. The gas sensor of the gas leak alarm has a characteristic that when the flammable gas adheres to the surface of the gas leak detection semiconductor (5) heated by the heater coil (6), the resistance suddenly decreases. . The gas leak alarm uses its characteristics to turn on the alarm lamp (7) and sound the alarm buzzer (8) when the detection output of the gas leak detection semiconductor (5) exceeds the set value. The structure is such that the user is notified before the concentration of the gas leaked into the air reaches the lower limit of the explosion concentration.

Therefore, the gas leak alarm device must detect the gas leak by continuing to supply an electric current to the gas sensor even in a normal time when no gas is leaking. Therefore, the system is designed to notify the user by turning off the power lamp (9) when the gas leak alarm is energized due to disconnection of the power plug, disconnection of the power cord, blown circuit fuse, etc.

[0005]

[Problems to be solved by the invention]

 However, because the location of the gas leak alarm was specified to be within 30 cm from the ceiling (an example of a city gas alarm), the power lamp went out of sight, and it was easy to miss turning off the power lamp.

[0006] Also, the alarm device has a problem that its existence is easily forgotten unless the alarm is frequently issued on a daily basis. Therefore, even if the power lamp in the off state is turned on in the line of sight of the user, There was a case where he did not notice that the alarm did not work.

Therefore, it has been difficult to understand the failure caused by the intermittent contact failure generated in the alarm device by the notification means by turning off the power lamp.

However, instead of turning off the power lamp, the means for notifying the abnormality of the alarm device is replaced by a means for continuing to operate by electricity (flashing of a strobe lamp, a warning buzzer, a warning voice, a warning message display, etc.). In this case, in order to notify the abnormality of the alarm device due to, for example, power failure or disconnection of the power outlet, it is necessary to rely on another power source (dry battery or battery) other than commercial power source. However, since the separate power source deteriorates in a few years, it was not practical considering the durability of the alarm device (a dozen years).

Further, the alarm device does not have daily convenience (for example, it does not have the convenience of assuring the day-to-day time like a clock) and even if it fails, it does not hinder daily life. Therefore, even if the user noticed that the alarm had broken down, there were cases where it was left as it was without being repaired.

Further, even if the alarm device continues to operate normally, the alarm device may not be activated due to the fact that a long period of time without alarm causes the user's safety consciousness to deteriorate and spoils aesthetics. In some cases, the power plug of the alarm device was intentionally unplugged in order to save electricity charges and secure power for other electronic devices.

The present invention solves the above problems, and an object of the present invention is to provide a system for detecting an abnormality in energization corresponding to the function of an alarm device.

[0012]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is a system having means for notifying an abnormality of an alarm device by normally stopping a clock having a function of indicating time. In other words, the user can know the failure of the alarm by stopping or delaying the clock.

[0013]

[Embodiment of the invention]

 Embodiments of the invention will be described based on examples with reference to the drawings. The embodiment shown in FIG. 1 is a detection means (3) for detecting the absence of electricity from a commercial power source (1) to an alarm device (2) for monitoring a disaster with a sensor, and this detection means (3). It is composed of a clock (4) which stops by inputting a signal from.

In the embodiment shown in FIG. 2, a means (3) for detecting an abnormality in the power consumption that has occurred in the alarm device (2) and a timepiece for stopping by inputting a signal from the detecting means (3). It is composed of (4).

For example, in a gas leak alarm device, since it is necessary to heat the gas detecting semiconductor (5) to 200 to 350 ° C. by the heater coil (6), most of the power consumption (2 W to 3 W) without alarm is generated. Is consumed by the heater coil (6). Therefore, the means (3) for detecting an abnormal decrease in power consumption can be used to estimate an abnormality in the energization due to the disconnection of the heater coil (6).

In the embodiment shown in FIG. 3, the alarm device (2) and the energization abnormality detection means (3) of the alarm device are provided in a timepiece (4) which is stopped by a signal from the energization abnormality detection means (3). It is built in. Therefore, since the watch is a watch, it looks good and there is no fear that the alarm will be removed because it will spoil the appearance.

In the embodiment shown in FIG. 4, the alarm abnormality detection means (3) of the alarm device is incorporated in the watch (4) which is stopped by the signal from the abnormality detection means (3), so that the alarm is generated. It is a system that enables the diversion of the conventional product of the alarm. In this case, since the watch (4) can be installed at a position where the user can easily see it, the notification of the power failure of the alarm device (clock stop or delay) is not overlooked.

In the embodiment shown in FIG. 5, the system is miniaturized by digitizing the timepiece (4) which is stopped by the signal from the current flow abnormality detecting means (3).

[0019]

[Effect of the invention]

 Since the present invention is configured as described above, it has the following effects.

The movement of the second hand (analog clock) or the blinking of dots (digital clock) of the timepiece according to the present invention guarantees that the alarm device is operating, so that the user can check the time each time. You can unconsciously check the function of the alarm device. In other words, since the alarm detection system has been provided with the convenience of a clock function on a daily basis, it is possible to add daily existence value to an alarm that was only used in the event of an extraordinary disaster. It was

[0021] Therefore, even if a long period of time without alarm causes a decrease in safety awareness of the user, the daily convenience of the clock function saves electricity charges and secures the power source of other electronic devices. Because of this, the power plug of the alarm will not be pulled out. Even if the watch stops due to a signal from the means for detecting an abnormality in the energization of the alarm device, the convenience of the clock function cannot be regained unless the alarm device is repaired, so the alarm device is repaired early.

In addition, when the clock is delayed, it can be inferred that the alarm device has intermittent inactivity during the delayed time, so that the failure can be detected early.

In addition, since the present invention notifies an abnormality in the energization of the alarm by stopping the clock rather than a notification means that keeps operating by electricity, a separate power supply is not required, and the problem of failure due to aged deterioration of the separate power supply is eliminated. Does not happen.
