散射高功率放大器监控系统设计

Design of Scattering High Power Amplifier Monitoring System

高功率放大器在散射通信系统中承担着发射信号的作用,其性能好坏影响通信链路的质量,而监控系统作为高功率放大器神经中枢,承担着设备控制、状态监测与保护的重任。针对散射通信系统对设备监控系统的远程、便捷及高可靠的要求,在MCU的硬件基础上,采用专用SLIP协议的RS485总线,分析设计了设备的工作状态及状态转移,利用循环结构及中断处理程序进行了系统实现。设备运行表明,该监控系统稳定可靠,可实时监测设备状态,对工程有一定参考意义。

High power amplifiers play a role in transmitting signals in scattering communication systems,and their performance affects the quality of communication links.As the neural center of high-power amplifiers,monitoring systems bear the heavy responsibility of equipment control,status monitoring and protection.In response to the remote,convenient,and highly reliable requirements of the scattering communication system for the equipment monitoring system,based on the hardware of MCU,a dedicated SLIP protocol RS485 bus is used to analyze and design the working status and state transition of the equipment.The system is implemented using a loop structure and interrupt processing program.The operation of the equipment indicates that the monitoring system is stable and reliable,and can monitor the equipment status in real time,which has certain reference significance for engineering.
