Step 2: choosing liquid crystal display option " scanning electric energy meter bar code ", " confirmation " button is clicked, CPU processor is by connecing
Power transmission road is transmitted/received, by reception/transmitting line, it is serial to be transferred to Symbol SE900 for " scanning electric energy meter bar code " instruction
Laser scanning engine；Start Symbol SE900 series laser scanning engine, alignment electric energy meter bar code is scanned；And it will sweep
Electric energy meter archive information is retouched, CPU processor is transferred to by reception/transmitting line, CPU processor compiles electric energy meter archives
Number sequence, storage is in FLASH disk data memory module；CPU processor is prompted by reception/transmitting line in liquid crystal display
" scanning successfully " printed words, facilitate user to confirm, then complete the scanning work of one piece of electric energy meter archives；In the same manner, successively
Scan remaining electric energy meter；
Step 3: " communications parameter " option is chosen in liquid crystal display after the completion of swepting slip shape code terminates click, debugging communications parameter passes through
Remote infrared and II type concentrator infrared port communicate, and click " lower to fill archives " button, and CPU processor reads FLASH disk data
Electric energy meter archives in storage, by reception/transmitting line, by Symbol SE900 series laser scanning engine, by this
It is attached in II type concentrator under area's electric energy meter archives parameter, CPU processor is transferred to by reception/transmitting line after the completion of lower dress
LCD MODULE, and show " under install into "；
Step 4: selection liquid crystal display " transparent transmission platform area data "-" clock of power meter " order, issues transparent transmission to II type concentrator
" clock of power meter " order, II type concentrator carries out transparent transmission meter reading to ammeter after receiving order, by data feedback after copy reading success
Symbol SE900 series laser scanning engine is given, CPU processor is transferred to by reception/transmitting line, CPU processor passes through
Reception/transmitting line is transferred to liquid crystal display and prompts " copy reading success "；After copy reading is unsuccessful three times, liquid crystal display prompt " is copied
Reading failure ", and start to carry out the copy reading work of next piece of electric energy meter, until all electric energy meter tests in platform area are completed；This process CPU
It is handled and will be in " copy reading success " and " copy reading failure " electric energy meter dossier to FLASH disk data storage；As all at
Function CPU processor will show that " being successfully tested " is transferred to liquid crystal display by reception/transmitting line, show if any failure measurement point
" test crash ", CPU processor transmit a signal to buzzer by control circuit, and with corresponding buzzer prompt tone, and
And display failure measurement point electric energy meter archives are transmitted to LCD MODULE by reception/transmitting line, and show that " test is lost
Lose ", facilitate live investigation problem；
Step 5: several aspects: 1, field electric energy table can be divided into according to the point-to-point investigation in test crash electric energy meter archives scene
Communication protocol, if use DL/T645-2007 communications protocol；2, whether field electric energy table RS485 wiring error；3, whether II
Type concentrator or RS485 mouthfuls of electric energy meter have damage；Check it is errorless after to failure electric energy meter archives carry out again above-mentioned steps three operate,
Until all successes；
Step 6: being clicked liquid crystal display " export station area test report " after being successfully tested；CPU processor reads FLASH disk data
The electric energy meter archives of storage, are printed by print module；Main website staff is referred to report, makes platform area archives；
Simple and fast, raising acquisition rate and working efficiency.
