Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 2, when conventional detection devices adopts serial detection mode, host computer is according to test item transmitting order to lower levels one by one, and the order issued is all according to after completing an epi-position, perform same operation to next epi-position again, all tables perform next after executing an order again.
As shown in Figure 3, during conventional detection devices employing parallel detection mode, host computer sends instructions down to many electric energy meters simultaneously, and a thread opened by every only table, and multiple thread carries out work simultaneously, each other independent operating.
As shown in Figure 1, realization of the present invention is on the host computer of pick-up unit and the basis of multiple epi-position parallel communications, and install an Intelligent interactive type detection device additional on each detection epi-position side, pick-up unit comprises device panel and control circuit board; Device panel comprises liquid crystal display and button, and control circuit board comprises main control unit, communication unit, power supply unit, liquid crystal cells and push-button unit; Main control unit is made up of 8 single-chip microcomputers (model is ATMEGA64L) and clock circuit, main control unit is connected with the host computer of pick-up unit by communication unit, receive the director data sent by host computer or send data to host computer, main control unit and liquid crystal display, key-press input unit, communication unit are all by being electrically connected.Communication unit is made up of communication chip (model is SN65LBC184) and auxiliary circuit; auxiliary circuit is the protection circuit adding the circuit components such as pull-up, pull down resistor and unidirectional Transient Suppression Diode at the output terminal of signal of communication, and this circuit effectively can prevent excessive voltage, the interference such as anti-lightning strike.Power supply unit receives from the power supply input outside device, and provide power supply to export through the treatment circuit of power supply unit for each unit on whole circuit board, liquid crystal cells is connected with liquid crystal display with main control unit respectively, corresponding information is shown on liquid crystal display according to the data that master control sends, push-button unit is connected with button with main control unit respectively, the positional information of the key that is pressed is inputed to main control unit, device panel has 5 buttons, be defined as YES respectively, NO, F1, F2, F3, the first two button represents the correctness of ammeter execution result respectively, the implication that rear three buttons are corresponding different according to the content of liquid crystal display.
When detecting a certain subfunction, main control unit is as the control axis of device, be responsible for receiving the instruction of being sent by host computer, instruction sent to liquid crystal cells, is shown by liquid crystal display, ammeter testing staff observes liquid crystal display content, operate ammeter, the result then performed by ammeter is by key-press input, and main control unit receives key information, be uploaded to host computer after process, complete a certain testing and successfully feed back testing result; When ammeter performs the result of detection and requirement does not meet, the liquid crystal of this device can show requirement and go host computer to input the prompting of ammeter display information, testing staff observes this displaying contents, the displaying contents of ammeter, then this content is inputted at host computer, complete the writing task of ammeter testing result, analyze for testing staff and judge that whether testing result is qualified.
Wherein, device execution electric energy meter programming key is pressed testing process and is: first carry out self-inspection after device corresponding in a certain epi-position powers on, then host computer instruction is waited for, after the electric energy meter programming key of main control unit reception host computer presses test instruction, main control unit sends data to liquid crystal cells, liquid crystal display shows two row information as Fig. 4, be respectively " please press ammeter programming key then press YES key " and " YES: button is successfully; NO: button failure "; testing staff removes the programming key pressing corresponding epi-position after seeing liquid crystal display content, programming bond energy situation about being enough pressed, and testing staff can press YES button at device panel; after the main control unit of device receives key information; transmit information that programming key successfully presses to host computer, this tests this epi-position ammeter and performs correctly, and it is qualified to detect; otherwise, namely programming key can not be pressed; testing staff presses NO button, and ammeter performs failure, detects defective.
Wherein, device arranges the testing process that card arranges table number function and is performing local charge control electric energy meter table number: host computer transmission table number arranges card and arranges ammeter instruction to ammeter, control the supporting parts of stage body simultaneously and table number is arranged card insertion ammeter, the implementation status of this process can synchronously be presented on the liquid crystal panel of interactive device, as Fig. 5.Testing staff observes the state of ammeter change, liquid crystal screen display be that table number arranges card and inserts after ammeter, the inquiry message of ammeter display result, as Fig. 6.If ammeter display Card Reader success or ERR-10, by YES key, information is uploaded, this test passes, not display, selects NO key, test failure, or selects F3 key retry.Repeat this again to detect after three times, after ammeter does not still have clear and definite information, upper transmission instruction is to device, require the information that liquid crystal display " please operate computer input reason ", testing staff goes to the information of host computer input " it is reactionless that ammeter insertion table number arranges card " after observing this information, this information can mend as the later stage reference data surveying this function, after input information, host computer sends and performs next command to ammeter and device, and the liquid crystal display picture of device is switched to next flow process.
Finally should be noted that: only illustrate that technical scheme of the present invention is not intended to limit in conjunction with above-described embodiment.Those of ordinary skill in the field are to be understood that: those skilled in the art can modify to the specific embodiment of the present invention or equivalent replacement, but these amendments or change are all being applied among the claims awaited the reply.
