为了实现调频发射机控制系统的智能化,设计改造了调频发射机供电电源控制电路,设计添加了调频同轴开关控制电路,在调频机柜内设计增加了相应的控制接口。针对不同的控制功能,分别进行了各自约束条件的设定和流程图的设计,结合相关PLC编程,实现了调频发射机自动开关机、主备机自动倒机、故障自动倒机等一系列智能化控制功能,并确保了各项控制功能的安全、稳定和可靠。
In order to realize the intelligent control system of the FM transmitter, the control circuit of the power supply of the FM transmitter is designed and modified. The control circuit of the FM coaxial switch is added in the design, and the corresponding control interface is added in the FM cabinet. For different control functions, respectively, the constraints of their respective settings and flow chart design, combined with the relevant PLC programming, to achieve a FM transmitter automatic switch, the main machine automatic machine down, automatic fault down and a series of intelligent Control functions, and ensure the safety, stability and reliability of various control functions.
