Field of the Invention The present invention relates to a gas alarm device and a method for controlling a gas sensor, and more particularly to a gas alarm device used in proximity to a gas supply point, such as a household gas sensor, and a method for controlling such a gas sensor.

0 will be explained. In the conventional gas alarm device 300 including the gas sensor 110, the gas sensor 110 is constantly operated in order to detect a gas leak in a gas device connected to the gas pipe 330. At this time, since the flow rate of the gas in the gas pipe 330 extending to the gas device is not considered with respect to the operation of the gas sensor 110, the gas sensor 110 is energized even when the gas device is not used.

命の低下につながっていた。However, since the gas sensor is always energized irrespective of the gas usage state, the following problems have occurred in the conventional gas alarm device. First, power is consumed even when the gas is not used, which increases the power consumption of the apparatus, thereby wasting power. In the case of a battery-operated alarm, the battery life was shortened. Second, since the gas sensor is always energized and placed in a used state, the gas sensor deteriorates in a short period of time, causing a reduction in sensor life. Third, since gas detection is performed even when gas is not being used, false detection of gas such as insecticides may generate an alarm (false alarm), which also results in power consumption and sensor life. Had led to a decline.

いう誤報をなくすことができる。With the above configuration, the gas sensor is not operated at all times, but the flow rate of the gas can be monitored, and the operation frequency of the gas sensor can be adjusted based on the flow rate. When the gas flow rate is low and the gas flow rate is high, the operation frequency of the gas sensor can be increased, and a gas alarm device that performs an efficient gas detection operation can be provided. Therefore, the operation time of the gas sensor is shorter than when the gas sensor is constantly energized, so that power consumption can be reduced. Further, since the gas sensor deteriorates when energized, the life of the gas sensor can be extended by shortening the energizing time of the gas sensor. Furthermore, since gas is detected based on the gas flow rate, gas is used.When the gas flow rate is high, the gas leak can be reliably detected, and when the gas flow rate is low, the gas leak detection is performed. Control can be provided such that there are few attempts. Accordingly, it is possible to eliminate a false alarm that a gas leak alarm is issued by detecting a spray such as an insecticide or other gas when the gas is not flowing.

When the power control unit is installed outside the gas alarm device, the gas alarm device itself may be a conventional gas alarm device without a power control unit, and thus the existing equipment resources are effectively used. can do.
