It will start automatically, after start completion, the initial setting up to Agilent 8960, Agilent signal source E4438C can be sequentially completed,
And open successively test software and test station plc communication port, test station and RF switch communication port, test software with
Extraneous PLC server communications port, and then it is automatically performed test system electrification, a series of standards of initial setting up and open communication port
Standby work；
(2) acquisition terminal enters detection station PLC actions：When acquisition terminal controls logistics to acquisition terminal GPRS intelligence by assembly line PLC
Can be before detection station jacking transferring when, assembly line PLC puts in storage request to test station transmission, and test station PLC, which is received, to put in storage
When in after request and storehouse without detection terminal, test station PLC is sent to assembly line PLC allows warehouse entry to instruct；At this point, detection station
PLC is sequentially completed stepping belt and rotates forward completion pallet warehouse entry, stepper motor advance completion pallet arrival horizontal checkout position, pallet
Jacking completes pallet and reaches vertical test position, plugs into clamping completion binding post in place；
(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, acquisition terminal can be sent to inspection software to bit instruction；At this point, test software is logical
It crosses control line traffic control detection station PLC to power on left side terminal in shielded box, while RF switch is switched into left side coupling
Plywood completes the preparation before testing left side acquisition terminal；Then, Agilent 8960 is as simulation main website and acquisition terminal
Carry out foundation call, transmission power, phase error, frequency error, switch frequency spectrum, modulation spectrum, receiving sensitivity, burst
Power over time, end nine test items of call are tested；
(4) after completing left side acquisition terminal test, test software is disconnected by controlling line traffic control detection station PLC in shielded box
Left side terminal supplying power simultaneously powers on right side termination, while RF switch is switched to right side coupling plate；Then, control peace is prompt
Human relations 8960 simulate main website and complete to establish 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 is soft
Test result can be stored in local main control computer and be sent to extraneous PLC servers by part, and notify server export；
(5) acquisition terminal goes out detection station PLC actions：After being respectively completed acquisition terminal detection in left and right in pallet, test software meeting
By control line request export is sent to detection station PLC；At this point, detection station PLC, which is respectively completed to plug into loosen, completes wiring
Column is withdrawn, pallet decline completion pallet arrival goes out bin location vertically, stepper motor retrogressing completion pallet arrival level goes out bin location,
Pallet export is completed in the reversion of stepping belt.
