Abstract
The utility model discloses a kind of coal-face bump warning system based on image, this warning system by installing video camera near coal-face 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 alarm signal.This warning system has taken into full account the various characteristic feature of coal face bump, implement simple, more adequately can judge the bump of coal-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 coal-face 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 coal-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 coal-face 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 coal-face 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.; Concrete grammar is as follows:
1. underground coal mine, places the video camera with mobile detection alert function on the hydraulic support or coal-winning machine of coal-face, in coal-face air intake lane, in coal-face return airway; In coal-face, coal-face air intake lane, in coal-face return airway, 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 coal-face and all methane transducer alarm linkages, when this coal-face has video camera to report to the police, and during methane transducer alarm free, then send bump alarm signal.
2. this system comprises further: camera installation locations is near top, tunnel or be highly greater than 2 meters.
3. this system comprises further: the reconnaissance range being arranged on the video camera on coal face hydraulic support or on coal-winning machine is coal-winning machine and scraper plate non-occluded area.
4. this system comprises further: the reconnaissance range being arranged on the video camera of coal-face air intake lane and return airway is the region of close work plane.
5. this system comprises further: the video camera using mobile detection function while of having multizone, can detect, detect when more than one piece object moves simultaneously and send mobile alarm signal multiple regions at multiple object places that original position is fixed.

Detailed description of the invention
Video camera placement location as shown in Figure 1, specifically comprises:
1. on the submarginal hydraulic support of coal-face (101).
2. in coal-face return airway (102).
3. in coal-face air intake lane (103).
4. coal-face upper corner methane transducer (104)
5. coal-face methane transducer (105)
6. coal-face air intake lane methane transducer (106)
7. coal-face return airway methane transducer (107)
As shown in Figure 2, the coal-face 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.
