摘要
双绞线可以长距离传输视频信号,并可以有效的避免工业现场中的各种干扰。基本原理是在发射端将非平衡的视频信号转换为平衡的视频信号,在接收端将平衡的视频信号还原为非平衡的视频信号与显示器连接。关键是发射器与接受器的设计与制作,传输过程中对高频信号的补偿和预提升。
Video signal in controlling system can be transmitted perfectly over twisted-pair, The basic principle is transforming single-ended video signal into differential signal in the driver. It is transformed back into single ended video signal in a receiver. The balance transmission driver and the differential receiver are introduced. The key is the design and making of transmitter and receiver to enhance and compensate high frequency signal.
