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 above and other purpose, feature and the advantage of the present invention will be 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 the detector unit in mine with down-hole well control platform, and the information for detecting is sent to well monitoring by detector unit
Platform and down-hole well control platform, on well, monitor supervision platform is connected with down-hole well control Platform communication, and down-hole can be believed by downhole monitoring platform
Breath is sent to monitor supervision platform on well, understands downhole conditions in real time in order to personnel on well, and on well, monitor supervision platform can be by the electricity that communicates
Cable sends control instruction to downhole monitoring platform.Down-hole downhole monitoring platform is respectively at power supply, blower fan, alarm unit, emergent photograph
The monitoring of fire damp, real-time regulation rotation speed of fan are responsible in bright unit and positioning unit connection, downhole monitoring unit, and are occurring
Down-hole personnel position can be positioned in time by positioning unit during accident, open luminaire.
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 includes 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 changer, 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 with monitor supervision platform on well by first communication module, by second
Monitoring module is connected with downhole monitoring platform, DSP control module by firedamp sensor, temperature sensor, humidity sensor and
The signal collected by CCTV camera 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 that main frame and standby host, main frame and standby host connect respectively at ups power, it is 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
