摘要
介绍了一种用于单片机实时控制系统的抗干扰设计方法。该方法用可编程芯片 82 5 4组成实时控制系统的Watchdog电路 ;用 815 5中的RAM保存系统重要信息的副本 ,并且采用保护式写入。
Microcontroller's anti-interference design method is introduced,which uses programmable interval timer 8254 as the Watchdog circuit,and uses write-protected methods to save the system's important information in 8155 RAM for system reboot.Actual uses show that this method can insure the microcontroller system reliable work in high elect-magnetic interference circument.
