Embodiment Construction
[0020] The invention provides a method for starting a watchdog in an anti-jamming system, and the method for starting a watchdog in the anti-jamming system includes the following steps:
[0021] 1) Determine whether to close the watchdog mechanism according to external conditions; if yes, clear the watchdog count and watchdog interrupt count; watchdog interrupt is invalid, watchdog reset is invalid; if not, go to step 2 ), the specific implementation is:
[0022] 1.1) Receive external conditions; the external conditions are system reset, power-on and system air and ground status;
[0023] 1.2) If any of the above external conditions prohibits the operation of the watchdog mechanism, the watchdog mechanism is turned off, and the watchdog count is cleared, and the watchdog interrupt count is cleared; the watchdog interrupt is invalid, and the watchdog Reset invalid;
[0024] If none of the above-mentioned external conditions prohibits the operation of the watchdog mechanism, t...
