Abstract
The invention discloses an underground coal mine gas monitoring system. The underground coal mine gas monitoring system comprises a gas sensor, a display unit, a single chip microcomputer, a sound and light alarm unit, a real-time communication unit, a data processing unit and a computer. According to the underground coal mine gas monitoring system, the gas concentration monitored by the system in different environments can be displayed in real time, powerful data processing capacity of a PC (Personal Computer) is utilized for analyzing and saving data, and measured results are displayed on a software interface through serial port communication software, therefore, that workers can know underground working conditions more intuitively, and then carry out corresponding processing and control is facilitated.
Description
Technical field
The present invention relates to a kind of monitoring system, specifically a kind of coal mine gas monitoring system, belongs to Safety of Coal Mine Production field.
Background technology
In colliery, contain the flammable explosive gas such as a large amount of methane (CH4), after having an accident, can cause huge economic loss, jeopardize miner's life.Along with the expansion of updating and exploiting scale of Coal Mining Technology means and the continuous extension of mining depth, potential safety hazard is more and more.Particularly heavy, especially big gas accident shared ratio in coal mining accident is also more and more higher for gas accident.If gas accident is not controlled, just can not realize the stable of Safety of Coal Mine Production situation, also just cannot ensure the sustainable and healthy development of coal industry.So, coal mine gas gas is monitored fast and accurately and seemed and be even more important, the research and development of inflammable and explosive mist monitoring system is also become to the problem that people pay close attention to always.
Summary of the invention
Goal of the invention: a kind of coal mine gas monitoring system is provided, can carries out Real-Time Monitoring to coal mine gas concentration, send at any time audible and visible alarm.
Technical scheme: a kind of coal mine gas monitoring system, comprises gas sensor, display unit, single-chip microcomputer, acousto-optic warning unit, real-time communication unit and data processing unit.
Operating principle: gas sensor, a kind of sensing element of energy perception methane in environment gas and concentration thereof, it can will convert the signal of telecommunication to gaseous species and concentration dependent information; Display unit, according to measuring-signal, carries out transfer of data by data to be displayed by corresponding manner by single-chip microcomputer and is shown in instrument to Graphics Processing module; Acousto-optic warning unit, in the time that gas-monitoring concentration exceeds setting alarming value, sends sound and light alarm; Real-time communication unit, carries out data communication by image data by RS-485 communication modes; Data processing unit, realizes collection, analysis and the preservation of gas data.
Beneficial effect: the gas concentration under the varying environment that the present invention can real-time display system monitors, use the data-handling capacity that PC is powerful to analyze save data, and by serial communication software, measured result is shown to software interface, be convenient to the operating mode that staff understands down-hole more intuitively, implement respective handling and control.
Brief description of the drawings
Fig. 1 is theory of constitution schematic diagram of the present invention.
Detailed description of the invention
Further the present invention is set forth below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of coal mine gas monitoring system, comprises gas sensor, display unit, single-chip microcomputer, acousto-optic warning unit, real-time communication unit, data processing unit and computer.
Gas sensor, a kind of sensing element of energy perception methane in environment gas and concentration thereof, it can will convert the signal of telecommunication to gaseous species and concentration dependent information; Display unit, according to measuring-signal, carries out transfer of data by data to be displayed by corresponding manner by single-chip microcomputer and is shown in instrument to Graphics Processing module; Acousto-optic warning unit, in the time that gas-monitoring concentration exceeds setting alarming value, sends sound and light alarm; Real-time communication unit, carries out data communication by image data by RS-485 communication modes; Data processing unit, realizes collection, analysis and the preservation of gas data.
Further, consider the distance of transfer of data, size and the economic factor of data volume, between described computer and single-chip microcomputer, communication mode adopts RS-485 agreement.
Further again, be CH4 for the main component of coal mine gas, described gas sensor is CH4 gas sensor.
