Abstract
The utility model provides a high-precision underground gas concentration detecting and alarming device comprising a micro-nano sensor module, an analog-to-digital conversion module, a main control module, a voice alarming device and a display module. The high-precision underground gas concentration detecting and alarming device is characterized in that the micro-nano sensor module, the analog-to-digital conversion module, the main control module and the display module are connected in sequence; and the main control module is further connected with the voice alarming device. The micro-nano sensor module is used for carrying out high-precision measurement on the underground gas concentration and carrying out signal conversion and amplification on a detected signal through the analog-to-digital conversion module; by comparing a parameter with a pre-set upper limit through the main control module, the voice alarming module is used for carrying out voice alarming when the received parameter is greater than the original set value; and finally, the main control module is used for transmitting relevant data into the display module so as to display the relevant data.
Description
Technical field
The utility model relates to a kind of fire damp concentration detection alarm device, especially down-hole high precision methane Concentration Measurement warning device.
Background technology
It is to prevent that the colliery from gas explosion taking place, guarantee the important measures of personal safety and production safety that coal mine gas concentration is accurately measured with real-time Monitoring and Controlling.China is used for the equipment of coal mine underground monitoring gas density at present, does not also adopt the microsensor technology of receiving.
Summary of the invention
It is main control module that the utility model adopts single-chip microcomputer, is main peripheral cell to receive microsensor, have the measuring accuracy height, simple in structure, reliability is high, explosion-proof, easy to operate, be convenient to advantage such as maintenance.
The utility model solves the technical scheme that its technical matters adopted: comprise and receive microsensor module, analog-to-digital conversion module, main control module, audio alert module, display module; It is characterized in that: receiving microsensor module, analog-to-digital conversion module, main control module, display module connects successively, and the main control module also is connected with the audio alert module.The microsensor module of receiving is carried out high precision to fire damp concentration and is measured; And detection signal is carried out conversion of signals through analog-to-digital conversion module amplify; Through the main control module this parameter and original higher limit of setting are compared; When the parameter that receives was higher than former setting value, the audio alert module was carried out audio alert, and last main control module is sent related data into display module and shown.
The beneficial effect of the utility model is, measuring accuracy height, intuitive display, accurately, and advantage such as easy to use and reliable has been represented the recent development trend of down-hole high precision methane Concentration Measurement warning device, has higher utility.
Description of drawings
