Specifically, the utility model discloses in:
combustible gas detection module
The sensor is a catalytic combustion type or infrared optical type combustible gas detection sensor. The catalytic combustion type combustible gas detection sensor usually comprises a pair of detection elements and compensation elements, and the elements oxidize combustible gas and generate a large amount of heat during detection of the sensor, so that the sensor is required to be arranged at a gas outlet of a labyrinth when the catalytic combustion type combustible gas sensor is adopted. The infrared optical type combustible gas sensor mainly detects the change of alkane combustible gas in the field environment by the absorption principle of an infrared light source. Combustible gas detects the module through combustible gas and detects combustible gas concentration in the environment to with concentration signal transmission to central control module, and then judge combustible gas concentration in the air.
This compound smoke maze of feeling can detect two kinds of conflagration circumstances through this combustible gas detection module, and one kind is whether to have combustible gas in the monitoring environment, and another kind is whether to have the emergence of conflagration for detecting. The composite smoke-sensing maze can effectively detect the concentration of combustible gas in the environment, and when combustible gas exists in the environment, alarm data is output; when smoke, temperature and humidity change, carbon monoxide and the like are detected in the environment and combustible gas is detected, a fire disaster is proved to happen, and alarm information is output at the moment.
