(3) GPRS is detected：The system detectio software of main control computer is always detected detection station PLC states by control line,
After detection station PLC completes above-mentioned action, concentrator can be sent to inspection software to bit instruction；At this point, test software passes through
Control line traffic control detection station PLC powers on left side terminal in shielded box, while RF switch is switched to left side coupling
Plate completes the preparation before testing left side concentrator；Then, Agilent 8960 is built as simulation main website with concentrator
Vertical call, transmission power, phase error, frequency error, switch frequency spectrum, modulation spectrum, receiving sensitivity, burst power pair
Time, end nine test items of call are tested；
(4) after completing left side concentrator test, test software is left in line traffic control detection station PLC disconnection shielded boxes by controlling
Lateral terminal power supply simultaneously powers on right side termination, while RF switch is switched to right side coupling plate；Then, Agilent is controlled
8960 simulation main websites complete to establish call, transmission power, phase error, frequency error, switch frequency spectrum, modulation frequency with right side termination
Spectrum, receiving sensitivity, burst power over time, the test for terminating nine test items of call；After the completion of test, test software
Test result can be stored in local main control computer and be sent to extraneous PLC servers, and notify server export；
(5) concentrator goes out detection station PLC actions：After being respectively completed concentrator detection in left and right in pallet, test software can pass through
Control line sends request export to detection station PLC；At this point, detection station PLC be respectively completed plug into loosen complete binding post remove
Decline from, pallet complete pallet reach go out bin location vertically, stepper motor retreats and completes pallet arrival level and go out bin location, stepping
Pallet export is completed in belt reversion.
