【摘要】 应陕西广播数字设备厂要求,结合调频广播发射机微机控制器项目技术要求,将分布式控制系统设计思想应用到广播发射机微机控制器硬件电路的设计中,采用多颗51单片机分别控制电源信号采集板和功率信号采集板,分担了系统风险,提高了系统的可靠性;对于数据存储、故障记录和菜单显示等管理任务则集中在主控板单片机中,实现了管理的集中和良好的人机界面;最后给出了对待干扰问题在硬件电路模拟量通道和串口通道设计中的解决方法。更多还原

【Abstract】 Using the idea of DCS designation,adopts a multi-CPUs framework to simplify the hardware structure and improve the system’s stability and share the risk of system,and use one MCU as main controller to memorize and display the data,besides administrating the others by serial RS232 communication.In the end,this paper gives some effective methods on avoiding electromagnetic interference in analog and communication channel.更多还原
