Often；When the sampling precision of current protective relaying device to be checked is more than default precision threshold, alarm and calling module can determine that and adopt
Sample precision result of determination is normal.Further, the warning information can also be shown by display device.
In the case where the sampling precision of current protective relaying device to be checked is less than or equal to default precision threshold, if
Continue call result information generating module 203, misoperation easily occurs in protective relaying device to be checked, alarm and calling module can be with
Action message is replaced by default slightly inspection message, the testing result information of the current protective relaying device to be checked of generation, without must
Be further continued for call result information generating module 203, directly when according to the testing sequence using next protective relaying device as
Sampling module 202 and object information generation module 203 are called in current protective relaying device to be checked, repetition, until generation is needed
Examine the testing result information of protective relaying device.
In the case where the sampling precision of current protective relaying device to be checked is less than or equal to default precision threshold, then with
Reflect the sampling sensor or Sampling device operation irregularity in current protective relaying device to be checked, now alert and call mould
Block sends sampling warning information, and tester can be helped to understand current protective relaying device to be checked and specifically sampled situation, so
Alarm and calling module directly obtain the sampling precision of next protective relaying device according to the testing sequence afterwards, and generate next
The testing result information of protective relaying device can be omitted until the testing result information of all protective relaying devices to be checked of generation
Unnecessary detection is carried out to abnormal protective relaying device to be checked, so that the time expended needed for saving detection, improves detection efficiency.
Embodiment described above only expresses the several embodiments of the present invention, and it describes more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Shield scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
