Embodiment

As shown in Figure 2, when the traditional detection device adopted the serial detection mode, host computer was according to test item transmitting order to lower levels one by one, and the order that issues all is according to after finishing an epi-position, again next epi-position is carried out same operation, all tables are carried out next bar after executing an order again.

As shown in Figure 3, when the traditional detection device adopted the parallel detection mode, host computer sent instructions down simultaneously to many electric energy meters, and every table is opened a thread, and a plurality of threads carry out work, independent operating each other simultaneously.

As shown in Figure 1, realization of the present utility model is on the basis of the host computer of pick-up unit and a plurality of epi-position parallel communicationss, detects the epi-position side at each and installs an intelligent interactive pick-up unit additional, and this device comprises: device panel and control circuit board; On the device panel liquid crystal display and button are arranged, control circuit board comprises main control unit, communication unit, power supply unit, liquid crystal cells, push-button unit; Device panel and control circuit board are realized being electrically connected by contact pin.(form for (ATMEGA64L) and clock circuit by model by 8 single-chip microcomputers for main control unit, main control unit links to each other with the host computer of pick-up unit by communication unit, the director data that reception is sent by host computer or send data to host computer, main control unit and liquid crystal cells, 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 be add at the output terminal of signal of communication draw, the holding circuit of circuit component such as pull down resistor and unidirectional Transient Suppression Diode, this circuit can effectively prevent excessive voltage, interference such as anti-lightning strike.Power supply unit receives from the input of the power supply outside the device, and the treatment circuit of process power supply unit provides power supply output for each unit on the entire circuit plate, liquid crystal cells links to each other with liquid crystal display with main control unit respectively, the data presentation corresponding information that sends according to master control is on liquid crystal display, push-button unit links to each other with button with main control unit respectively, the positional information of the key that is pressed is inputed to main control unit, have 5 buttons on the device panel, be defined as YES respectively, NO, F1, F2, F3, preceding two buttons are represented the correctness of ammeter execution result respectively, the implication that back 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 maincenter of device, be responsible for receiving the instruction of sending, instruction is sent to liquid crystal cells, show by liquid crystal display by host computer, the ammeter testing staff observes the liquid crystal display content, ammeter is operated, and the result that ammeter is carried out imports by button then, and main control unit receives key information, be uploaded to host computer after the processing, finish a certain testing and successful detection feedback result; When result who carry out to detect when ammeter and requirement do not meet, the liquid crystal of this device can go host computer to import the prompting of ammeter display message by display requirement, the testing staff observes this displaying contents, the displaying contents of ammeter, import this content at host computer then, finish the writing task of ammeter testing result, whether qualified for testing staff's analysis and judgement testing result.

Wherein, device execution electric energy meter programming key is pressed testing process and is: at first carry out self check after corresponding device powers on a certain epi-position, wait for the host computer instruction then, after the electric energy meter programming key of main control unit reception host computer is pressed test instruction, main control unit sends data to liquid crystal cells, liquid crystal display shows two row information such as Fig. 4, be respectively " please press ammeter programming key " then by YES key and " YES: button is successfully; NO: button failure "; the testing staff sees the programming key that goes after the liquid crystal display content by corresponding epi-position, the situation that the programming bond energy enough is pressed, the testing staff can press the YES button at the device panel; after the main control unit of device receives key information; transmit the information that the programming key successfully presses and give host computer, this tests this epi-position ammeter and carries out correctly, it is qualified to detect; otherwise, promptly the key of programming can not be pressed; the testing staff presses the NO button, and the ammeter execution is failed, and detects defective.

Wherein, device is provided with the testing process that card is provided with the table number function and is carrying out local expense control electric energy meter table number: host computer transmission table number is provided with card and electric table number is set instructs to ammeter, control the supporting parts of stage body simultaneously table number is provided with card insertion ammeter, the implementation status of this process can be presented on the liquid crystal display of interactive device, as Fig. 5 synchronously.The testing staff observes the state variation of ammeter, and what show on the liquid crystal display is that the inquiry message of ammeter display result was as Fig. 6 after table number was provided with card insertion ammeter.If ammeter shows Card Reader success or ERR-10, by YES key, information uploading, this test passes does not show, selects the NO key, test failure, or select F3 key retry.After repeating this again and detecting three times, after ammeter does not still have clear and definite information, upper transmission is instructed to device, information such as Fig. 7 of requiring liquid crystal display " to ask operational computations machine input reason ", the testing staff observes the information of going to host computer input " ammeter insert table number card is set reactionless " after this information, this information can be used as the reference data that the later stage benefit is surveyed this function, behind the input information, host computer sends carries out next command to ammeter and device, and the liquid crystal display picture of device switches to next flow process.
