摘要
随着中国加快推进地面数字电视(DTMB)无线覆盖工程的建设,提高技术人员对地面数字电视发射系统设备的维护维修水平、故障判断排除能力刻不容缓。本文结合由包头市微波总站建设的市级地面数字电视单频网项目,对其运行中常见的发射机故障进行了分析和总结。
As the country speeds up the construction of Digital Terrestrial Multimedia Broadcast(DTMB)wireless coverage project,it is significant to improve technical personnel’s ability in facility maintenance and fault diagnosis of DTMB system.Combined with prefecture-level DTMB single frequency network project constructed by Baotou Microwave Relay Station,this paper analyzes and summarizes common transmitter failures during its operation.
