Technical field
The utility model relates to a kind of video image transmission system, is particularly useful for a kind of coal mining working face video image transmission system that the coal mining working face uses.
Background technology
Coal-face is first line that mine is produced, and the safety in production of guaranteeing coal-face could guarantee the normal operation of coal mining enterprise.The main equipment of coal-face has coal-winning machine, drag conveyor, disintegrating machine, elevating conveyor, hydraulic support, belt, pumping plant etc. at present; The coal-face course of work is: coal-winning machine moves under hydraulic support, on the drag conveyor; The broken coal of the cylinder of coal-winning machine rotation is adopted the coal that falls through equipment delivery entruckings to ground such as drag conveyor, disintegrating machine, elevating conveyor, belt conveyors; Hydraulic support and drag conveyor be fulcrum each other, pushes ahead with the exploitation of working face.Coal-face running environment is complicated, and in order to realize unmanned working face development trend, coal-face main equipment long-distance video image monitoring is heavy to closing under the coal mine.At coal-face the video image monitoring system is installed; Can in time know the production run state of coal-face; Satisfy the demand of automated mining, utilize Active Eyes simultaneously, the ground monitoring personnel can directly monitor the down-hole situation in real time; Keep watch on and write down the on-the-spot safety in production situation of underground work intuitively, and help the realization of remote expert video diagnosis.
At present, several kinds of communication systems below the transmission of coal-face video signal is adopted:
A kind of is wire communication, and through laying dedicated communications cable or Optical Fiber Transmission video signal, wire transmission can realize timely, the accurately transmission of signal; But the Coal Production site contour is complicated, many dust, electromagnetic interference serious, the equipment dismounting is frequent, so cable and joint component damage easily, and wiring cost generally is directly proportional with data bandwidth; The cost of transmission video signal is higher; In case go wrong, search and change the cable difficulty, and cause waste easily.
Another kind is to adopt radio communication, and its wiring is simple, and cost is low, and signal has reduced system cost and difficulty of construction through microwave transmission; But owing to the working face fluctuations, adopt this mode to lose vision signal under the coal mine through regular meeting.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy for installation, and is compatible good, the coal mining working face video image transmission system that vision signal is stable.
For realizing above-mentioned purpose; The coal mining working face video image transmission system of the utility model; Comprise a plurality of acquisition terminals of being installed at interval on the coal-face hydraulic support, be installed in the concentrator on the coal-winning machine track crossheading; A plurality of acquisition terminals are connected with concentrator through power line, and concentrator connects colliery comprehensive automation looped network through switch, is connected to the ground monitoring main frame through colliery comprehensive automation looped network; Explosion-proof type shell is housed respectively on a plurality of acquisition terminals and the concentrator.
Described acquisition terminal is connected to form by coupler, bridge and video equipment; Described concentrator comprises coupler and bridge.
Beneficial effect: the utility model is through installing acquisition terminal on hydraulic support; And lead to and receive in the concentrator; Send at last in the ground host, utilize existing power line and colliery comprehensive automation looped network, not only reduced construction and material cost but also made communication line reliable and stable; Compatible good, running status that can the real time monitoring coal-face.It is simple in structure, and is easy for installation, compatible good, and vision signal is stable.
