摘要
根据对高功率放大器监控系统的要求,选择C8051F单片机作为控制器,利用单片机本身的SMBus串行总线实现了监控与数据采集系统之间的数据交换,以及与远控系统之间的控制切换。使用TH25632A图形点阵式液晶显示模块作为功率放大器工作状态和参数显示器,使得监控人员随时可以方便、直观地了解功率放大器的工作状态和实时参数,实现了冗余功率放大器的在线切换。给出了系统硬件原理框图、串行数据总线收、发子程序流程图。
According to the requirement of the High Power Amplifier Monitored Control System, C8051 F, a single chip microcomputer, was used for the controller. SMBus, the serial bus, was used for the data exchange between the monitored control system and the data collection system, and the control of the cutover to the remote control systems. The TH25632A, graphic dot matrix liquid crystal display module, was used to display the work states and parameters of the power amplifiers. Then the monitored control technicians can know the work states and real time parameters of the power amplifiers easily and illustratively, and the online cutover function of redundant power amplifiers can be implemented. The schematic diagram of the hardware in the system and the send-receiver subroutine flowchart of the serial bus were also given in this paper.
