发射机自动化监控系统中,下位机与发射机之间的接口电路设计关系到整个系统的稳定和可靠,是系统设计的关键部分之一。我台共有10个频率20部发射机,涉及的机型五个厂家8种机型,在数据采集(数字输入DI、模拟输入AI)和控制(数字输出DO)方面需要采用不同的方式,实施过程中也解决了一些难题。将介绍硬件的各个子系统及解决的各种难题以供相关的发射机台站技术人员参考。
Transmitter automation monitoring system, the interface between the lower computer and the transmitter circuit design is related to the stability and reliability of the entire system, the system design is one of the key components. There are totally 10 transmitters in our country with 20 frequencies and 8 models from 5 manufacturers involved in this project. We need to adopt different methods in data acquisition (digital input DI, analog input AI) and control (digital output DO) The process also solved some problems. The various subsystems of the hardware and the various problems to be solved are presented for reference by the relevant transmitter station technician.
