Abstract
The invention discloses a distributed gas monitoring system which mainly comprises an above-hole monitoring platform and a downhole monitoring platform. The above-hole monitoring platform and the downhole monitoring platform are both connected with detection units in a mine. The detection units send detected information to the above-hole monitoring platform and the downhole monitoring platform. The above-hole monitoring platform is in communication connection with the downhole monitoring platform which sends downhole information to the above-hole monitoring platform. The above-hole monitoring platform sends a control command to the downhole monitoring platform through a communication cable. The downhole monitoring platform is connected with a plurality of fans mounted in different downhole areas. The fans have an automatic backward switching function and are used for working face air supply. When excessive gas is detected, the downhole monitoring platform stops the automatic backward switching function of the fans, and the fans in the excessive gas areas are all put into operation. By adoption of the coal mine gas alarm system, gas can be effectively monitored.

Fig. 2 is the structural representation of detector unit of the present invention；
Fig. 3 is the structural representation of downhole monitoring platform of the present invention；
Fig. 4 is the structural representation of monitor supervision platform in the present invention.
Specific embodiment
It is understandable to enable the above objects, features and advantages of the present invention to become apparent from, below in conjunction with the accompanying drawings to the concrete of the present invention
Embodiment is described in detail, and makes above and other purpose, feature and the advantage of the present invention and will become apparent from.In whole accompanying drawings
Middle identical reference indicates identical part.Not deliberately accompanying drawing drawn to scale, it is preferred that emphasis is illustrate the purport of the present invention.
As shown in figure 1, the gas monitoring system of the present invention mainly includes monitor supervision platform and downhole monitoring platform on well, monitor on well
Platform is connected with down-hole well control platform with the detector unit in mine, and the information for detecting is sent to well monitoring by detector unit
Platform and down-hole well control platform, monitor supervision platform is connected with down-hole well control Platform communication on well, and downhole monitoring platform can believe down-hole
Breath is sent to monitor supervision platform on well, and in order to personnel on well downhole conditions are understood in real time, and monitor supervision platform can be by the electricity that communicates on well
Cable to downhole monitoring platform sends control instruction.Down-hole downhole monitoring platform is respectively at power supply, blower fan, alarm unit, emergent photograph
Bright unit and positioning unit connect, and downhole monitoring unit is responsible for the monitoring of fire damp, real-time regulation rotation speed of fan, and is occurring
Down-hole personnel position can in time be positioned by positioning unit during accident, open lighting apparatus.
Fig. 2 is referred to, the detector unit is installed on the different region in down-hole, for example, can be filled every 100 meter amperes in tunnel
One, detector unit include firedamp sensor, temperature sensor, humidity sensor and CCTV camera, firedamp sensor,
Gas density signal, temperature signal and moisture signal detected by temperature sensor, humidity sensor, respectively through A/D
DSP control module is sent into after converter, CCTV camera is used to gather the picture signal in region, the encoded device of image
DSP control module is sent into after coding, DSP control module is connected by first communication module with monitor supervision platform on well, by second
Monitoring module is connected with downhole monitoring platform, DSP control module by firedamp sensor, temperature sensor, humidity sensor and
The signal that CCTV camera is collected sends to well monitor supervision platform and downhole monitoring platform, the memory module of DSP control module
Internal memory contains the alarm threshold value of gas density, after the gas density for detecting exceedes alarm threshold value, DSP control module driving sound
Light alarm module sends warning, and DSP control module is also connected with intercommunication module, personnel in the pit by intercommunication module can with well on
Monitor supervision platform or downhole monitoring platform realize intercommunication.
As shown in figure 3, the downhole monitoring platform includes main frame and standby host, main frame and standby host connect respectively at ups power, main
Function performed by machine and standby host is identical, and when main frame breaks down, system automatically switches to standby host, it is ensured that down-hole controls not
Interrupt.
