Abstract
The utility model discloses a gas monitoring system. Currently, a plurality of kinds of instruments can be used for coal mine gas detection, surface monitoring centers can know underground safety conditions at any time, some coal mines are even subjected to networking monitoring of scheduling and monitoring centers of provincial coal mine safety supervisory bureaus, however, gas explosion accidents still occur frequently, and gas explosion accidents are caused by the fact that the safety awareness of miners is not high and over-limit gas is not alarmed due to inconspicuous alarm signals of instruments. The gas monitoring system comprises a gas probe (1), wherein the gas probe is connected with an emitting chip (2) and is installed on a safety helmet or work clothes, the emitting chip is connected with an information receiving device (4) inside a mine through wireless signals, and the information receiving device is connected with a gas monitoring device (3) through a safety cable. The gas monitoring system is applicable to moving gas monitoring inside mines.
Description
Technical field:
The utility model relates to a kind of methane monitoring system.
Background technology:
At present, the instrument kind that coal mine gas detects is a lot, form monitoring system, communication network, can make aboveground monitoring center understand at any time the downhole safety situation, some collieries even with Coal Mine Safety Supervision Bureau of Shanxi Province's dispatch center networking monitoring, however, gas explosion accident still occurs again and again, and a reason is that miner's awareness of safety is not high, and the 2nd, because the instrument alarm signal is not obvious, gas exceeding limit also can not reported to the police, the 3rd, the installation follow-up is untimely.
Summary of the invention:
The purpose of this utility model is to provide a kind of methane monitoring system.
Above-mentioned purpose realizes by following technical scheme:
A kind of methane monitoring system, its composition comprises: the gas probe, described gas probe is connected with transmitting chip, described gas probe is arranged on safety helmet or work clothes, described transmitting chip is connected with information receiver in mine by wireless signal, and described information receiver is connected to methane monitoring instrument through safety cable.
Described methane monitoring system, described information receiver is equipped with amplifier, and described amplifier connects wave filter and remagnifier; Described methane monitoring instrument comprises housing, in described housing, central processing unit is installed, described central processing unit is connected with information collecting device, power circuit, voice alarm circuit, LCD display circuit, keyboard control circuit, actuating mechanism circuit respectively, and described actuating mechanism circuit is connected with analog switching circuit.
Described methane monitoring system, have LCD display, power switch, loudspeaker, control button on described housing, described LCD display is connected with described LCD display circuit, described power circuit is connected with described power switch, described loudspeaker is connected with described voice alarm circuit, and described control button is connected with described keyboard control circuit.
Described methane monitoring system, described gas probe is firedamp sensor.
Beneficial effect:
The mobile wireless gas probe that the utility model carries by the down-hole employee detects the concentration of the gas that detects in real time the position, various gas concentration value are passed to methane monitoring instrument, methane monitoring instrument judges whether gas exceeds normal gas density, if transfinite provide warning, corresponding measure is taked in prompting, avoid occuring gas explosion, ensure coal production and personal safety.
