Check it is wrong, governor circuit think gather measured value not over, not over the reason for be " returned data mistake ".
(3) gather actual value：Governor circuit receives the returned data of switching value measuring apparatus within the time of agreement.It is false
If the returned data for receiving is that " 03 03 02 00 00 " (CRC check code is not listed, and 03 represents address, and 03 is inquiry work(
Energy code, 02 is 2 byte datas, and 0000 is the air switch state value for returning).Governor circuit checked to returned data, if
Check it is wrong, governor circuit think gather actual value not over, not over the reason for be " returned data mistake ".
(4) calculation error：Governor circuit calculates the absolute of measured value in the case of second step and the 3rd step all pass through
Error.
(5) error-detecting：Governor circuit is checked to absolute error on the premise of the 4th step.If absolute error
0, governor circuit think switching value test not over, not over the reason for be " switching value exception ".
(6) test result is processed：If the 5th step inspection is passed through, governor circuit thinks that switching value test passes through.
Finally, test result all can be sent to detection outut device by governor circuit.Detection outut device receives governor circuit transmission
Test result, according to test whether pass through to carry out different process.If last switching value is tested, then work as reception
To be " test passes through ", then " test passes through " result is indicated into detected communication power supply watch-dog, is not otherwise temporarily made
Process.If what is received is " test not over ", will " test not over " result indicate with reason it is detected
On communication power supply watch-dog.
