单片机应用系统设计中的看门狗技术探究

Study on the Watchdog Technology in Reliability Designing in Single Chip Application System

针对单片机应用系统可能出现的受干扰而发生程序陷于死循环的现象,探讨了对其进行监视的方法,提出了用软、硬件看门狗技术对其改进的措施。

With considering unable-ending cycle in the process of practical use of single chip microcomputer system, this article discusses the ways of avoiding programs in single chip microcomputer going into unable-ending cycle by using software and hardware watchdog technology when single-chip-microcomputer system is disturbed.
