Station PLC be sequentially completed stepping belt rotate forward complete pallet warehouse entry, stepper motor advance complete pallet reach horizontal checkout position,
Pallet jacking completes pallet and reaches vertical test position, plugs into clamping completion binding post in place；
(3) wireless public network is detected：The system detectio software of main control computer is carried out to detection station PLC states always by control line
Detection, after detecting that station PLC completes above-mentioned action, can send special transformer terminals to bit instruction to inspection software；Now, test soft
Part is by controlling line traffic control to detect that station PLC carries out upper electricity to left side terminal in shielded box, while RF switch is switched into a left side
Side coupling plate completes the preparation before testing the special transformer terminals in left side；Then, Agilent 8960 is used as simulation main website and specially change
Terminal carries out foundation call, transmission power, phase error, frequency error, switch frequency spectrum, modulation spectrum, receiving sensitivity, burst
Pulse power is tested time, end nine test items of call；
(4) after left side specially transformer terminals test is completed, test software is by controlling line traffic control to detect that station PLC is disconnected in shielded box
Left side terminal supplying power simultaneously carries out upper electricity to right side termination, while RF switch is switched into right side coupling plate；Then, control peace is prompt
The simulation of human relations 8960 main website completes to set up call, transmission power, phase error, frequency error, switch frequency spectrum, modulation with right side termination
Frequency spectrum, receiving sensitivity, burst power over time, the test for terminating nine test items of call；After the completion of test, test soft
Test result can be stored in local main control computer and send to extraneous PLC servers by part, and notify server export；
(5) special transformer terminals go out to detect that station PLC is acted：After left and right specially transformer terminals detection in pallet is respectively completed, test software meeting
Request export is sent to detection station PLC by control line；Now, detection station PLC, which is respectively completed to plug into loosen, completes wiring
Post is withdrawn, pallet decline complete pallet reach vertically go out bin location, stepper motor retreat complete pallet arrival level go out bin location,
The reversion of stepping belt completes pallet export.
