Multifunctional gas concentration detector

Abstract

The invention discloses a multifunctional gas concentration detector, which includes an Atxmega64D4 microcontroller, a signal processing and acquisition device, a display device, a wireless communication device, an acousto-optic alarm and a button device; The output end of button device is connected with the input end of Atxmega64D4 microcontroller, and the input end of described signal processing and collection device is connected with the output end of Atxmega64D4 microcontroller, and described display device, wireless communication device, sound and light alarm and signal The output terminals of the processing and collecting device are connected; the signal processing and collecting device mainly include a methane measuring device and a carbon monoxide measuring device; the advantage of the present invention is that a multifunctional gas concentration detector of the present invention can detect methane gas and Simultaneously detects carbon monoxide gas, has a two-in-one detection function, and can also be connected to a PDA and individual rescue system through a wireless interface.

Description

technical field [0001] The invention relates to the technical field of safety monitoring systems, in particular to a multifunctional gas concentration detector. Background technique [0002] Coal is a solid combustible mineral gradually formed by ancient plants buried in the ground through complex biochemical and physical chemical changes. become. Coal is known as black gold and the food of industry. It has been one of the main energy sources used by the human world since the eighteenth century. Due to the limitations of natural geological conditions, underground mining conditions, miners' skills, technology and equipment, coal mines have always had problems such as poor safety and reliability and high frequency of safety accidents. [0003] Today, with the continuous development of mining technology, the safety of underground workers needs to be more and more guaranteed, but there are still many mining companies with a low degree of mechanization, which poses certain pote...

Problems solved by technology

Due to the constraints of natural geological conditions, underground mining conditions, miners' skills, technology and equipment, coal mines have always had problems such as poor safety and reliability and high frequency of safety accidents.

[0003] Today, with the continuous development of mining technology, the safety of underground workers needs to be more and more guaranteed, but there are still many mining companies with a low degree of mechanization, which poses certain potential risks to the life safety of on-site mining workers. Threats, especially for the detection and alarm of gas, there are still potential safety hazards, and there are still serious accidents caused by gas leakage every year
