Abstract
The invention provides an anti-explosion monitoring system for a coal mine. The anti-explosion monitoring system for the coal mine comprises a monitoring center positioned above a mine shaft, one or multiple underground substations positioned under the mine shaft and a monitoring device connected with the underground substations. The monitoring center comprises a monitoring mainframe, a database system, a display device and an alerting device. The monitoring device comprises a processor module, a sensor module, a nixie tube displaying module and an acousto-optical alerting module. The processor module is connected with the underground substations through a wireless transmission module. The underground substations are connected with the monitoring mainframe through a RS-485 bus. The anti-explosion monitoring system for the coal mine has the advantages that the gas concentration under the mine shaft is effectively monitored, the accuracy degree and the stability of monitoring of the system are improved, and the flexibility and the extendable capability of the system are improved.
Description
Technical field
The present invention relates to safety monitoring field, especially relate to a kind of coal mine explosion-proof monitoring system.
Background technology
Coal is the main energy sources of China, but along with the increase of pit mining scale and the degree of depth, the content also corresponding increase of coal mine gas.Coal mine gas is the mixture of multiple flammable explosive gas, and its main component is methane, and burning-point is very low, and when the ratio that it mixes with air reaches 5% to 16%, running into naked light will blast, and the safety in production in colliery in serious threat.Therefore, Real-Time Monitoring carries out to the concentration of coal mine gas extremely important in Colliery Security System.In the domestic mine of prior art, gas monitor equipment is also relatively backward, not only investigative range is little, and data transmission adopts wired mode, namely optical cable, electric power cable etc. is adopted, its retractility and expandability poor, namely system can not extend to production face position along with the propelling of development end after installing automatically, when the distance of development end and explosion-proof monitoring equipment exceeds monitoring range, cannot carry out real-time two effective methane gas monitor this crucial monitoring point of production face.
Summary of the invention
The object of the invention is the shortcoming overcoming prior art, a kind of coal mine explosion-proof monitoring system is provided.
Technical scheme of the present invention is:
Coal mine explosion-proof monitoring system, comprises and is positioned at aboveground monitoring center and the one or more underground substation being positioned at down-hole and the monitoring device be connected with described underground substation,
Described monitoring center comprises monitoring main frame, Database Systems, display unit and warning device, described monitoring main frame is connected with described Database Systems by bus, described display unit comprises display circuit and display screen, described monitoring main frame is connected with described display screen by described display circuit, described warning device is connected to the control signal output of described monitoring main frame
Described monitoring device comprises processor module, sensor assembly, numeral method module, sound and light alarm module, described sensor assembly is connected with described processor module by Signal-regulated kinase, described processor module is connected with described numeral method module, described sound and light alarm module respectively
Described processor module is connected with described underground substation by described wireless transport module,
Described underground substation is connected with described monitoring host computer by RS-485 bus.
The model of described processor adopts AT89S51 single-chip microcomputer.
The model of described wireless transport module adopts nrf905 wireless chip.
