Description
Technical field
The utility model relates to mine safety technical field, especially relates to a kind of underground coal mine Network Video Surveillance camera of self illumination function.
Background technology
In the U.S., colliery realizes high mechanization, and underground work personnel are little, and job specification, tunnel is unobstructed, once have an accident, be easy to withdraw, injures and deaths are little.And in China, mining mechanization degree is only 45%, miner troop be greatly educational level lower, train limited rural migrant worker, even there is the serious violation phenomenon such as down-hole smoking.Numerous miners like this, in the operating environment of highly dangerous, very easily have an accident, create greater casualties.The reason that important coal mining accident occurs is mainly reflected in: the information communication of ground and personnel in the pit not in time, ground staff is difficult to distribution and the handling situations of dynamically grasping personnel in the pit in time, once coal mining accident occurs, the efficiency of rescue and relief work, safety first-aid is low, searches and rescues weak effect.At present, coal mine operation is because away from ground, with a varied topography, bad environments, inconvenience is linked up with ground staff, if utilize Active Eyes, ground monitoring personnel then can directly monitor down-hole situation in real time, can not only monitor and record the safety in production situation at underground work scene intuitively, and energy Timeliness coverage accident potential, prevent trouble before it happens, also relevant first-hand image document can be provided for ex-post analysis accident, meanwhile, the relevant supervision department of higher level also can be checked by network remote and carry out situation, proposes amelioration method.But also there is following defect and deficiency in the video monitoring camera being used in underground coal mine in prior art:
1, monitoring camera visual angle is little.The visual angle size of monitoring camera directly determines the size of amount of information.The gun shaped camera horizon angular field of view that current underground coal mine extensively adopts generally all is less than 70 °, and vertical angle of view scope is generally all less than 30 °.And the horizontal view angle of eye is at 160 °, vertical angle of view is about 80 °.Little being easy in single monitoring camera visual angle causes monitoring dead angle, and needs more monitoring camera to obtain overall view monitoring.
2, cannot accurate synchronization between multiple monitoring camera.Current underground coal mine video monitoring system will adopt business Ethernet transmitting video-frequency flow, meets IEEE802.3 standard.Business Ethernet appears at 1972 the earliest, take office automation as target design, and do not consider the accurate synchronization problem between multiple terminal, transmission delay has uncertainty.Multiple monitoring camera carries out the nonsynchronous problem of video-splicing life period, cannot realize real seamless spliced.
3, operating temperature range is narrow, and hot environment cannot normally work.Current monitoring camera grade is generally business level, and maximum operating temperature is less than 70 degree, and under some particular surroundingss of underground coal mine, equipment cannot normally use.As accident rescue is on-the-spot, before ambient temperature does not drop to normal range (NR), more early obtain live video data better.
4, wiring cost is high.Current underground coal mine video monitoring system wiring adopts optical fiber or fire-retardant netting twine, and cost is higher, is unfavorable for large-scale use.
5, monitoring camera dynamic range is inadequate.Current monitoring camera is dynamically generally all less than 90db, if monitoring camera installation site is not chosen, is easy to the phenomenon occurring that dynamic range is inadequate, affects the quality of monitored picture.
6, monitoring camera does not have self illumination function, and under the low-light (level) environment of underground coal mine, or when a large amount of unlatching underground coal mine illuminating lamp, often there is the problem that partial exposure is not enough and local is over-exposed, monitored picture is of poor quality.
