摘要
介绍了P89C51RA单片机的性能和特点,设计了智能广播系统控制器。详细分析了该型号单片机ISP功能,实现了智能广播系统控制器的在系统升级。通过串口通信对PC主机命令进行接收并解析,实现对广播设备和广播分区的控制。系统成功地进行了系统调试,经长期运行表明,该系统结构简洁,运行稳定可靠,性价比高。
Controller in Intelligence Broadcast System is designed on the basis of introducing the characters and performance of P89CS1RA. The function of ISP in P89CS1RA is analyzed in detail, and then updating in system is realized. Furthermore, control of broadcast devices and broadcast area are carried out by decoding information through serial communication from PC host. In this way, the system debugging is successfully. Practical application shows that Intelligence Broadcast System is simplicity, steady and high performance price ratio.
