摘要
发射机是发射台的核心设备,其运行状态是否正常直接关系到中短波发射台播出广播节目质量的好坏,在线指标检测系统的建立,很方便地实现发射机运行指标的实时观测。本文通过对在线指标检测系统的建设分析,探讨了其建设的重要意义及在基层广播发射台的应用实现。
The transmitter is one of the key equipment in a transmitting station. Its running status is directly related to the broadcasting quality in a short wave transmitting station. The online indicator monitoring system achieves a real-time observation of transmitter performance conveniently. Based on the analysis of the construction of on-line indicator monitoring system, this paper discusses the significance of its construction and the application in basic radio transmitting stations.
