Embodiment Construction

[0014] Such as figure 1 As shown, a gas detection and alarm device includes a gas sensor 1, an oxygen sensor 2, and a temperature sensor 3 arranged underground for real-time collection of various environmental parameters, and the output terminals of the gas sensor 1, oxygen sensor 2, and temperature sensor 3 are all Carry out line connection with the input end of microprocessor 5 by amplifier 4; The output end of described microprocessor 5 is respectively connected with LED display screen 6, warning device 7 and the power switch 8 that is used to control underground power supply circuit; Microprocessor 5. The interactive connection has a relay route 9, and the relay route 9 transmits the downhole information to the upper computer 10 of the monitoring center on the well through wireless.

[0015] Further, the alarm device 7 is a buzzer and an alarm lamp.

[0016] working principle:

[0017] The gas concentration value collected by the gas sensor and the oxygen content and tem...

Abstract

The invention provides a gas detection alarm device which comprises acquisition devices. The acquisition devices are arranged in an underground environment and are used for acquiring various environmental parameters in real time, and output ends of the acquisition devices are connected with input ends of a microprocessor by wires; output ends of the microprocessor are respectively connected with an alarm device and a power switch used for controlling underground power supply circuits; a relay router is interactively connected with the microprocessor, and underground information is wirelessly transmitted to an upper computer of a ground monitoring center by the relay router. The gas detection alarm device has the advantages that serious accidents of gas combustion and explosion can be fundamentally greatly reduced owing to the audible and visual alarm actions of the alarm device and the power-off action of the power switch; the information is wirelessly transmitted via the relay router, so that an underground condition can be effectively known and controlled via the upper computer of the ground control center.

Description

technical field [0001] The invention relates to an underground safety monitoring system of a coal mine, in particular to a gas detection and alarm device. Background technique [0002] Under the influence of geological conditions, environment and toxic and harmful gases, various mining accidents occur frequently in coal mine operations, causing serious damage to life and property. Among the toxic and harmful gases, gas is the most harmful. Gas is a hydrocarbon gas stored in coal seams. The main component is methane. It is a flammable and explosive gas that poses a major threat to the safety of coal mine production. [0003] There are three conditions for gas to explode or burn, one is its concentration, the gas concentration in the air reaches 5% to 16%; combustion. And when the concentration of gas in the air is less than 5%, it will not burn, and when it is greater than 16%, it will neither explode nor burn. Therefore, the accurate detection of gas concentration has bec...
