Abstract
The utility model discloses a kind of driving face in coal mine bump warning system based on image, this warning system by installing video camera near driving face in coal mine relevant range, image change abnormal in real-time analysis guarded region and object move, combined situation as variation abnormality meets alert if, then send bump and report to the police and fail secure signal.This warning system has taken into full account the characteristic feature of driving face in coal mine bump, implement simple, more adequately can judge the bump of driving face, effective raising rescue efficiency, be conducive to administrative staff and take corresponding measure in time, avoid tunnel to block methane accumulation and cause the major accidents such as gas explosion, avoid or reduce casualties.
Description
Technical field
The utility model relates to a kind of driving face in coal mine bump warning system based on image, and this system relates to image procossing and the field such as to communicate.
Background technology
Coal is China's main energy sources, accounts for primary energy 70%.Coal industry is high risk industries, and the accidents such as gas, floods, fire, top board, coal dust annoying Safety of Coal Mine Production.In China's coal-mine generation severe and great casualty, majority is particularly serious gas accident, and the number of casualties that gas accident causes also is that in all coal mining accident, proportion is maximum.Therefore, gas accident control is very important.
Gas accident comprises the accidents such as gas explosion, bump, gas asphyxiation, gas combustion.Occur for avoiding or reducing bump accident, there has been proposed multiple coal or rock and gas outburst prevention treatment method, play an important role in Safety of Coal Mine Production work.But existing bump Real-Time Monitoring and forecasting procedure (comprising microseism, sound emission, electromagnetic radiation, infrared radiation etc.) rate of false alarm and rate of failing to report also higher, be difficult to the needs meeting Safety of Coal Mine Production.
Easily there is bump in the driving face of underground coal mine, after bump occurs, easily causes the staff near work plane scene to be landfilled or stranded; Bump can cause the blocking in tunnel near work plane in addition, makes dash not smooth, makes methane accumulation, easily cause gas explosion.If judge the bump in this region rapidly and accurately in the very first time, rescue can be organized as early as possible, strive for valuable rescue time, avoid or reduce landfill or the stranded casualties caused; And in time establishment officer takes treatment measures to blocking tunnel, effectively avoid the accidents such as the gas explosion caused due to methane accumulation, avoid or reduce because gas asphyxiation and gas explosion cause casualties.
Summary of the invention
When driving face in coal mine generation bump situation, have a large amount of coal petrographys and outwards gush out at a high speed, and bulk deposition is in work plane major part region, is even outwards gushed out by air intake lane and return airway.The utility model proposes a kind of driving face in coal mine bump warning system based on image according to this feature, and cardinal principle is, by adopting the motion and accumulation that find a large amount of coal petrographys abnormal in guarded region to video camera, realizes bump and reports to the police.Described warning system mainly comprises: storage server, monitoring host computer, monitoring guest machine, the network switch, down-hole switch, substation, video camera, methane transducer etc.; Particular content comprises:
1. underground coal mine, in the digging laneway of driving face or on development machine, one or both sides, digging laneway fork are placed has the video camera of mobile detection alert function; In driving face, digging laneway return, methane transducer is installed; Video camera, for detecting the object of which movement of specific region exception, can send mobile alarm signal automatically; All video cameras of same driving face and all methane transducer alarm linkages, when this driving face has video camera to report to the police, and during methane transducer alarm free, then send bump alarm signal.
2. camera installation locations is near top, tunnel or be highly greater than 2 meters.
3. the video camera in pair digging laneway or on development machine is installed and reconnaissance range is coal-winning machine and scraper plate non-occluded area.
4. the installation of the video camera of pair both sides, digging laneway fork and reconnaissance range are the region near work plane.
5. use the video camera of mobile detection function while that there is multizone, can detect multiple regions at multiple object places that original position is fixed, detect when more than one piece object moves simultaneously and send mobile alarm signal.
Accompanying drawing explanation
Fig. 1 driving face video camera and methane transducer installation site schematic diagram.
Fig. 2 is based on the driving face in coal mine bump warning system schematic diagram of image.
Fig. 3 is that video camera and methane transducer link logic connectivity diagram.
The workflow schematic diagram that Fig. 4 video management and bump are reported to the police.
Detailed description of the invention
Video camera placement location as shown in Figure 1, specifically comprises:
1. (101) in digging laneway.
2. in the tunnel of the side of digging laneway fork air-out (102).
3. in the tunnel of the side of digging laneway fork air intake (103).
4. driving face methane transducer (104).
5. digging laneway return methane transducer (105).
As shown in Figure 2, the driving face in coal mine bump warning system based on image mainly comprises:
1. storage server (201); Be responsible for gathering camera signal, mobile alarm signal, methane transducer data and equipment working condition signal, storing, and provide inquiry to transfer service for user.
2. monitoring host computer (202); There is sound and light of alarm, production management personnel check live video image, mobile alarm situation, methane transducer data and equipment working condition by monitoring host computer, manually can send bump alarm signal and fail secure signal, cut off underground coal mine whole non-intrinsically safe secured electrical device power supply (DPS), issue dispatch command notice and withdraw from coal mine underground operators.And history monitor data can be transferred from storage server.
3. monitor guest machine (203); When monitoring host computer breaks down, carry out work by monitoring guest machine.
4. the network switch (204); Be responsible for management and the exchanges data of the equipment of the mining Ethernet of all accesses.
5. down-hole switch (205); Be responsible for access and the exchanges data of substation, there is flameproof enclosure, meet underground coal mine requirement of explosion proof.
6. substation (206); The access of the equipment of being responsible for and exchanges data, have flameproof enclosure, meet underground coal mine requirement of explosion proof.
7. video camera (207); Adopt the digital network camera with mobile detection function, be furnished with the explosion-resistant enclosure meeting coal mine explosion-proof requirement, there is alarm signal output function.
8. methane transducer (208); Methane transducer is gamut or the dense methane transducer of height, and has auto-alarm function.
