| 摘 要： | 根据单片机防止程序飞出的原理,创新性的提出了PC机在无人看管下,计算机如何判断当前的运行状态,以及在无法相应其他进程时,实现自动重启的方法。从单片机的看门狗实现原理,可在PC机上实现类似看门狗的功能。介绍了PC WATHDOG的软硬件实现,以及如何设计串口通讯协议,使PC WATCHDOG通过串口接收发送通讯帧和控制帧,进行交互,达到看门狗的功能。

| Abstract: | Based on the theory of preventing the program from going out of control in MCU,a method is introduced of how to autoboot the pc without anybody at present when the pc can't not respond to other processes.From the theory and implementation of the watchdog,we can design a PC WATCHDOG to work on the PC.Details of the implementation of hardware and software are introduced,and the SPCP(Serial Port Communication Protocol) is designed to communicate though Serial Port. |
