It is worth for 18A, the actually detected value of PFC electric currents is 19A, more than given threshold 18A, therefore, is judged as PFC overcurrent protections, and
" PFC overcurrent protections " be present in assuming it is assumed that can then determine that the hypothesis of " PFC overcurrent protections " is set up in the failure.
Step S2, if verify during the failure is assumed at least one assumes to set up, it will verify that the hypothesis set up is made
For the second fault diagnosis result.
Wherein, if verify during the failure is assumed at least one assumes to set up, it will verify that establishment is assumed to be used as the
Two fault diagnosis results.
Step S3, if each hypothesis verified during the failure is assumed is invalid, searched in preset rules
At least one rule assumed during the failure is assumed can be released, and it is false using the regular premise found as new failure
If re-start the checking.
Conclusion is searched i.e. in preset rules and includes at least one rule assumed during the failure is assumed, specifically, will
Each hypothesis during the conclusion of each single item rule is assumed with the failure in preset rules is matched, and determines that the failure is false
The hypothesis that can be at least released in if by a rule, i.e. in the conclusion regular included at least one it is assumed that and will look into
The regular premise found is as new failure it is assumed that re-starting checking, i.e. step S1~S3 is re-executed, until certain is false
If it is identified.
When obtained fault diagnosis result includes Fisrt fault diagnostic result and the second fault diagnosis result, by described
One fault diagnosis result and fault diagnosis result of the identical conclusion as the equipment in second fault diagnosis result.
Alternatively, it is if any it is assumed that can not be found in preset rules to release in assuming for the failure
The rule arbitrarily assumed, then the new fault message of the equipment is obtained, to verify whether any hypothesis is set up.
If any hypothesis verified during the failure is assumed is invalid, and can not be released by rule, it will require outside
Information source (user or sensor etc.) provides true (new fault message), to verify whether the hypothesis is set up.In reasoning process
In among it is true, information newly inputted etc. exists in the form of group.Such as, detect that air intake vent air quantity is smaller, can be true with user
Recognize and whether more than 1 year do not cleaned filter screen, so as to be confirmed whether be because not cleaning filter screen for a long time, caused by air quantity it is smaller.
