Description
Technical field
The utility model belongs to field of video transmission, especially a kind of novel twisted-pair feeder transmission system.
Background technology
Along with developing rapidly of science and technology, use the video monitoring technology widely in the security monitoring field, the video camera in the supervisory control system is transferred to Surveillance center with the vision signal of being shot with video-corder by the communications cable, monitors in real time for Surveillance center.At present, transmission of video signals generally uses coaxial cable to carry out transmission of video signals, and the problem of its existence is: (1) coaxial cable is subjected to interference from outside signals easily and causes transmission signals to lose, poor transmission; (2) coaxial cable carries out transfer of data and is easy to generate decay, makes that data output distance is short; (3) coaxial cable cost height, cable wiring manufacture inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of antijamming capability is strong, long transmission distance, cost is low and the novel twisted-pair feeder transmission system of easy construction.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of novel twisted-pair feeder transmission system, connect and compose successively by video amplification module, video processing circuits, video transmitter, video receiver and video output interface, vision signal is connected to the input of video amplification module, video output interface is connected on the DVR equipment, is connected by twisted-pair feeder between video transmitter and the video receiver.
And described twisted-pair feeder is 5 class unshielded twisted pairs.
And described video amplification module adopts high-speed video multiplexer LMH6574, and described video processing circuits adopts the HK02257705 circuit board, and described video transmitter adopts the active twisted-pair feeder transmitter of EL-UT01T series; Video receiver adopts initiatively twisted-pair feeder transmission receiver module of EL-UT16R series, and video output interface adopts 16 road 25-pin D-Sub to change BNC male seat winding displacement.
Advantage of the present utility model and good effect are:
1, this twisted-pair feeder transmission system is connected together sending ending equipment and receiving device by twisted-pair feeder and carries out transfer of data, because the twisted-pair feeder transmission has more than the strong antijamming capability of coaxial cable, even several in same cable transmit different signals respectively to twisted-pair feeder, can not disturb each other, guarantee the reliability of signal transmission.
2, this twisted-pair feeder transmission system can be carried out processing and amplifying with vision signal to be sent at transmitting terminal, and vision signal is compensated gain at video receiver, therefore, transmission range and transmission quality have been improved effectively, improved the definition of transmitting video image, the brightness and color and the real-time that have kept original picture reach 1km or when farther, picture intelligence is undistorted substantially in transmission range.
3, this twisted-pair feeder transmission system can adopt at present that widely used 5 class unshielded twisted pairs connect up, and it is with low cost, wiring is convenient, cable utilance height, be convenient to cable wiring manufacture.
4, employed video transmitter of this twisted-pair feeder transmission system and video receiver all adopt existing equipment, have reliability height, characteristics such as easy to use, convenient for installation and maintenance.
5, the utility model is reasonable in design, by twisted-pair feeder sending ending equipment and receiving device are connected together and carry out transfer of data, improve transmission range and transmission quality effectively, had reliability height, with low cost, characteristics such as wiring is convenient and convenient for installation and maintenance.
