Abstract

The invention discloses a mine gas detection system designed based on an adjustable voltage stabilizing integrated circuit. The mine gas detection system is equipped with a power supply circuit, an alarm lamp circuit, a gas detection circuit, a silicon controlled circuit and an alarm circuit. The power supply circuit is internally provided with a power supply GB, an input filter circuit, an adjustable voltage stabilizing chip IC1 and an output circuit, the power supply GB is connected to the input filter circuit, the input filter circuit is connected to the adjustable voltage stabilizing chip IC1, and the adjustable voltage stabilizing chip IC1 is connected to the output circuit. The detection system provided by the invention is used for detecting gas in mines, and gives real-time alarm so as to avoid gas poisoning of staff. In terms of power supply design, the adjustable voltage stabilizing chip is utilized to carry the power supply circuit so as to supply power to to-be-fed circuits in the whole mine gas detection system, and the supplied power is voltage stabilized electric energy, accordingly the situation that the whole mine gas detection system cannot work stably because of voltage instability can be avoided, thus avoiding detection failure and safety liability accidents.

Description

technical field [0001] The invention relates to the fields of coal mining, processing technology and the like, specifically, a mine gas detection system designed based on an adjustable voltage stabilizing integrated circuit. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mines include large areas above and below ground and associated facilities. A coal mine is a reasonable space excavated by humans wh...
