| Abstract: | Watchdog technique is a major measure for computer control system anti-jamming. In this paper we analyze the problems caused by watchdog's own failure and the influence of watchdog resetting on the microcomputer system in practice, then explore the principle of the problems and the corresponding solutions. Examples have proved that the measure proposed in this paper can effectively enhance the operating stability of microcomputer control system. |
