Problems solved by technology

Therefore, gas detection is an important part of coal mine work. The existing gas detection is to detect and record the gas in the methane detection area with a tile detector that is carried around manually. On the one hand, the above method will increase the labor intensity and reduce the gas detection. At the same time, human negligence leads to various types of methane gas exceeding the standard in mines. If it is not discovered in time, it will cause major accidents; great harm to the human body

Abstract

The invention discloses a wireless digital gas detector. The wireless digital gas detector comprises a gas detecting emitter and a gas detecting receiver, wherein the gas detecting emitter is in wireless transmission connection with the gas detecting receiver through a ZIGBEE; the gas detecting receiver comprises an STM32F107 single chip microcomputer which is used as a core, a contactable color screen with a liquid crystal display dimension of 3.2 inch, a combined button and three independent buttons, and a ZIGBEE wireless transmission module; a data storage module and a lithium battery charging management module are held in hands for receiving parameters, sent by a nearby sending end, of methane and gas, recording, checking, storing, and exporting data through a USB port. The gas detecting emitter comprises CC2530 which is used as a main chip, an infrared laser acquisition sensor acquiring part, and a lithium battery charging management module; and infrared laser sensor data is acquired, and the data is transmitted onto the gas detecting receiver in a wireless mode through the ZIGBEE. The wireless digital gas detector solves the problem that labor power is needed for gas detection in the prior art.

Description

technical field [0001] The invention belongs to the field of coal mine gas detection equipment, in particular to a wireless digital gas detection instrument used in coal mines. Background technique [0002] Coal mining is a high-risk industry, and many accidents are inseparable from the methane gas in the mine. Methane gas detection is mainly to detect the concentration of methane gas in the wind flow and the volume ratio of methane gas in the areas where methane gas is easily generated in mining face, tunneling roadway, return air roadway, etc. If there is methane gas in the working environment, such as The explosion of electromechanical equipment is likely to cause gas explosion; gas explosion will bring catastrophic and destructive consequences to coal mines. Therefore, gas detection is an important part of coal mine work. The existing gas detection is to detect and record the gas in the methane detection area with a tile detector that is carried around manually. The abo...
