line calibration mode
Under the line calibration mode, the test host 1 sends a first line calibration instruction to a first test terminal through the second wireless communication module 25, and sends a second line calibration instruction to a second test terminal, the test terminal 1 receives the first line calibration instruction through the second wireless communication module 25, and all the test terminals 2 disconnect the KA 8. The first test terminal closes KA6 and KA7, then closes KA1, the second test terminal closes KA1 after receiving the second calibration command, then closes KA5, and current signals flow to the following steps: the battery anode of the first test terminal → the KA6 contact of the first test terminal → the KA1 contact of the first test terminal → the train line → the KA1 contact of the second test terminal → the KA5 contact of the second test terminal → the ground line of the second test terminal → the train body (the test terminal 2 and the ground point of the host are the same body, the body is a conductor) → the light emitting diode of the first test terminal → the KA7 contact of the first test terminal → the battery cathode of the first test terminal, at this time, the photodiode of the first test terminal receives the light signal of the light emitting diode and is conducted, the detection circuit 23 sends a high level signal (i.e., a light signal) to the input port of the second control module 24 through the photodiode, which indicates that the lead wire between the 1 pin of the connector X1 and the 1 pin of the connector X2 is normally conducted, the second control module 24 of the first test terminal determines that the two ends of the train line are correctly connected, and transmits the received optical signal to the test mainframe 1 through the second wireless communication module 25. If the signal received by the second control module 24 at the first test terminal is low (i.e., no light signal), it indicates that the wire between pin 1 of the connector X1 and pin 1 of the connector X2 is not through. If the input port of the second control module 24 of the first test terminal receives a high signal after the relay of the first test terminal is closed and before the relay of the second test terminal is closed, it indicates that the wire between pin 1 of X1 and pin 1 of connector X2 is shorted to the vehicle body. When the wiring fault exists, the host machine automatically alarms. The two test terminals 2 are respectively closed in turn at KA2, KA3 and KA4, and the test host 1 generates a line calibration report.
Insulation test mode
Under the insulation test mode, the test host 1 sends an insulation test instruction to the first test terminal and the second test terminal, the first test terminal and the second test terminal close KA8 first, then the first test terminal and the second test terminal close KA1 and relays (corresponding relays in KA 1-KA 4 in the legend, and the number of actual relays corresponds to the number of train lines) corresponding to the train lines with the same insulation test voltage level, and all other relays are disconnected. Then loading insulation test voltage on the tested train line by a megohmmeter in the test host 1 according to the insulation grade of the train line through an insulation withstand voltage test power line, and after the insulation test of all the train lines is completed, sending a tested resistance value to a first control module of the test host 1 by the megohmmeter in the test host 1 through an internal data line so that the first control module generates an insulation test report according to the insulation resistance between each train line and a train body, which is measured by the megohmmeter; the train line insulation grades are DC1500V, DC1000V and DC 500V.

And then loading a preset test voltage on the tested train line for a certain time (generally 60 seconds) by a voltage withstand test machine in the test host 1 according to the insulation grade of the train line through an insulation voltage withstand test power line, and after the test is finished, sending the leakage current value of each group of train lines to the train body to the second control module 24 of the test host 1 through an internal data line by the voltage withstand test machine so that the second control module 24 generates a voltage withstand test report according to the leakage current value measured by the voltage withstand test machine.

Each test terminal and the test host 1 are in continuous communication, after the test is started, the signal sending end sends test signals to each contact pin of the connector in sequence according to received wireless signals, other test terminals monitor the conduction state of each path at the moment, after any test terminal receives a connection signal, the position information of the connection contact pin is fed back to the test host 1 through wireless communication, and the test host 1 compares the received position information with a wiring table to generate a wiring test report. And during the insulation and voltage resistance test, the two ends of the same train line and the train lines with the same insulation and voltage resistance grade are loaded with test voltage at the same time.
