Parameter adjustable combustion gas leakage alarm device and method

Abstract

A parameter adjustable combustion gas leakage alarm device comprising a microprocessor, a plurality of combustion gas sensors and a plurality of audible-visual alarm devices, wherein the plurality ofcombustion gas sensors are arranged on a combustion gas transmission line and are in signal connection with the microprocessor, and the plurality of audible-visual alarm devices are in signal connection with the microprocessor; each audible-visual alarm device comprises an audible alarm device and a visual alarm device; the parameter adjustable combustion gas leakage alarm device is characterizedin that each combustion gas sensor is in signal connection with the microprocessor via a threshold value adjustable module, the threshold value adjustable module comprises a rheostat and a double voltage comparator, an output end of the rheostat is connected with one input end of the double voltage comparator, an output end of each combustion gas sensor is connected with the other input end of thedouble voltage comparator, and an output end of the double voltage comparator is in signal connection with the microprocessor. The alarm device can be used for detecting different combustion gases, usage cost can be lowered, and convenient and safe usage can be realized.

Description

technical field [0001] The invention relates to the technical field of gas leakage monitoring, in particular to a parameter-adjustable gas leakage alarm device and method. Background technique [0002] At present, gas leakage has become a major hidden danger to family safety, and how to timely and accurately monitor gas leakage has become an important issue that people care about. [0003] The disadvantage of the traditional gas leakage alarm device is that it lacks the ability to monitor multiple gas leakages at the same time; the user cannot know the monitoring status in real time; the sound alarm cannot be turned off independently, which affects maintenance personnel. Contents of the invention [0004] The main purpose of the present invention is to provide a gas leakage alarm device and method with adjustable parameters. By adjusting the parameters, it is possible to detect the leakage of different gases and give an alarm in time. [0005] In order to achieve the abov...
