Abstract
The invention discloses a handheld coal mine gas concentration detecting device, and belongs to the technical field of automatic control. The handheld coal mine gas concentration detecting device is characterized by comprising a single-chip microcomputer controller (1), a gas concentration sensing module (2), a keyboard module (3), a warning lamp alarming module (4), a loudspeaking alarming module (5), a liquid crystal display module (6) and a power module (7). Compared with the prior art, the device has the advantages that the structure is simple, the control is convenient, the reliability is high, and the maintenance is convenient.
Description
Technical field
The invention belongs to automatic control technology field, in particular, belong to a kind of hand-held coal mine gas concentration pick-up unit.
Background technology
Gas Outburst is the proprietary term of a disaster, refer to the increase of the increase along with coal mining depth, gas bearing capacity, define in coal seam under terrestrial stress effect, under the graviational interaction of gas release, rockburst is made to break through burden, a large amount of gas of abrupt release and coal and a kind of geologic hazard of causing.Coal mining depth is darker, and the energy of gas abrupt release also can be larger.Gas Outburst and gas explosion are two concepts, but disaster all comes from gas.Gas Outburst is a kind of geologic hazard, after a large amount of harmful gases pours in instantaneously, can be formed and suffocate, but accident of not necessarily blasting.But if there is the explosion caused accident of meeting after following three kinds of situations, one is reach more than 12% with content of oxygen in air, and two is that gas density reaches between 5% to 16%, and three is run into naked light, and ignition temperature reaches more than 650 degree.Gas Outburst is a global difficult problem in control gas technology, can't accomplish at present to take precautions against completely.At present along with the continuous increase of domestic coal mining depth and gas density, gas burst accident has the situation increased year by year.Monitor in real time the gas density in mine in order to effective, usually adopt distributed methane Concentration Measurement device in coal mine, this technology can not effectively be monitored the concentration in mine in real time.
Summary of the invention
The present invention, in order to effectively solve above technical matters, gives a kind of hand-held coal mine gas concentration pick-up unit.
A kind of hand-held coal mine gas concentration pick-up unit of the present invention, is characterized in that: comprise singlechip controller, gas density induction module, Keysheet module, warning lamp alarm module, alarm module of raising one's voice, LCD MODULE, power module;
Described singlechip controller is connected with described gas density induction module, described singlechip controller is connected with described Keysheet module, described singlechip controller is connected with described warning lamp alarm module, described singlechip controller is connected with described alarm module of raising one's voice, described singlechip controller is connected with described LCD MODULE, and described singlechip controller is connected with described power module.
The present invention is compared with prior art: have structure simple, control the advantages such as convenient, reliability is high, easy to maintenance.
