Enter terminal 15 to connect with experiment power supply.
Two sides testing crew is switched on after checking phase checking device 1 and 2 wiring of phase checking device, as shown in Fig. 2, the power supply mould of device
Block 17 is started to work, and standard working power is provided.Select phase checking device 1 for drive end, by controlling input module 20 to signal
Analyzer-controller 22 sends instruction and is set as aggressive mode.It selects phase checking device 2 for abutting end, is provided accordingly to mating die
Formula.Drive end and abutting end testing crew, which are sent by control input module 20 to signal analyzer-controller 22, to be instructed, to corresponding
Messaging parameter be configured, then selection start nuclear phase.
After selection starts nuclear phase, the signal analyzer-controller 22 of drive end phase checking device 1 can issue instruction control channel and turn
Parallel operation 29 selects A phase line as communication channel, and channel switches 29 can return signal analyzer-controller 22 after completing phase selection
Phase selection complete, synchronous signal analyzer-controller 22 can to output module 21 send instruct, by the result of phase selection configuration electronics
Screen shows " selected A phase ".Signal analyzer-controller 22, can be to oscillator 23, encoder after receiving phase selection and completing signal
24, modulator 26 issues instruction and starts to transmit.Meanwhile signal analyzer-controller 22 can refer to decoder 25 and the transmission of demodulator 27
Order starts to collect mail.Decoder 25 will decode result and be sent to the progress data analysis of signal analyzer-controller 22.Bandpass filter 29
For being filtered to the signal on transmission line of electricity, exclusive PCR.At this point, result output module 21 is aobvious in the electronic curtain of configuration
Show " checking A phase ".
The phase checking device 2 of abutting end and the phase checking device 1 of drive end are identical, select A phase line for communication channel first, show
Show " selected A phase ", starting transmits and collection of letters function, and display " is cooperating verification A phase ".
In A phase audit process, the phase checking device of drive end and abutting end transmitted on the A phase line path channels respectively selected and
It collects mail, if the signal that one end phase checking device receives is demodulated, decode and is identified as " opposite side A phase transmits signal " after analyzing,
Route A phase is checked correctly, and the signal analyzer-controller 22 of the end phase checking device will be issued to encoder 24 and be instructed at this time, is being compiled
" A phase is checked correctly " information is added in code signal, transmits notice to opposite side.The phase checking device collection of letters in opposite side is identified as that " A phase is checked just
After really ", " having been received by A phase to check correctly " can be added in encoded signal, and transmit notice to opposite side.Both ends phase checking device passes through
Communicate with each other clear A phase check it is correct and after, show " checking A phase to finish, A phase is correct " in electronic curtain.Then both ends
The signal analyzer-controller 22 of phase checking device sends to channel switches 29 and instructs, and translated channel starts to check next phase.Together
Reason, both ends phase checking device successively cooperate verification B, C phase.
If the abutting end phase sequence and drive end is inconsistent or the phase line is there are breakpoint in phase sequence audit process,
Drive end and abutting end phase checking device can not receive opposite side checking signal.At this point, drive end phase checking device keeps communication channel
Constant, abutting end phase checking device successively selects B phase, C phase channel to cooperate nuclear phase within the set time.Drive end and abutting end nuclear phase
After device automatically analyzes separate corresponding relationship according to Content of Communication, nuclear phase is finished.The signal analyzer-controller of both ends phase checking device
22 send instruction, the output phase checked result on electronic curtain to result output module 21.If abutting end phase checking device exists
Opposite side checking signal can not be still received after converting all channels, then illustrates that there are breakpoints for the phase line.Abutting end phase checking device
Electronic curtain shows nuclear phase result and testing crew is prompted to carry out communication processing.
