said incrementing said error count value comprising:
increasing the error count value by a second value;
the first value and the second value are related to the time complexity of a program operated by a system corresponding to the current external watchdog.
8. A monitoring device for an external watchdog, comprising:
the error count value acquisition module is used for acquiring an error count value corresponding to at least one monitoring period before the current monitoring period of the external watchdog;
an abnormal count value changing module, configured to change an abnormal count value of the external watchdog according to an error count value corresponding to at least one monitoring period preceding a current monitoring period;
and the abnormality judging module is used for judging whether the external watchdog is abnormal according to the abnormality count value.
9. An electronic device, comprising: memory, a processor and a computer program stored in the memory and executable on the processor, the processor implementing the steps of the method according to any one of claims 1-7 when the computer program is executed.
10. A computer readable storage medium having instructions stored thereon which, when run on a computer, cause the computer to perform the method of any of claims 1-7.
