广播电视微波电路传输通道保护技术

Protection Technology of Transmission Channel of Radio and Television Microwave Circuit

在微波接力传输过程中,要全方位综合考虑障碍物对传输质量的影响,如高层建筑物、山坡和丘陵等。微波电路传输遇到中断信号会出现反射与阻断现象,造成电视节目出现传输故障。微波通道的传输信号只能通过直线传播,发射天线与接收天线中不能出现拐点与阻挡物。一旦广播电视微波电路通道出现故障,阻碍电视信号的传输,则会导致广播电视节目无法正常播出,造成严重的损失。

In the process of microwave relay transmission,we should comprehensively consider the impact of obstacles on transmission quality,such as high-rise buildings,hillsides and hills.In case of interruption signal in microwave circuit transmission,reflection and blocking will occur,resulting in transmission failure of TV programs.The transmission signal can only propagate through a straight line.There are no inflection points and obstacles in the transmitting antenna and receiving antenna.Once the microwave circuit channel of radio and television fails and hinders the transmission of television signals,radio and television programs will not be broadcast normally,resulting in serious losses.
