In the present embodiment, testing workstation is mainly used in that testing requirement is relatively concentrated, the application of the batch of test logic more complicated, and tester's use test workstation carries out operation and detection in batches to electric energy meter.Testing workstation comprises PC; This PC calls the service logic of application server, and the execution result of application server 2 is shown, checks for user.Traditional electric energy meter production test system, error checking program normally provides compared with Biao Tai producer, and production testing system is program independently separately, and error-detecting data are difficult to sum up in the point that in production test system.In the present embodiment, in workshop, be also provided with and show platform 8, show platform 8 and be connected, pass to electric energy meter for reading power meters error in dipping and by relevant information by RS485 interface with electric energy meter and one of them testing workstation (the first testing workstation 71) respectively.Specifically, by electric energy meter error calibration procedure with show platform 8 and carry out cooperating, the measuring parameter of check and correction electric energy meter.Compare with traditional ammeter production test system, the electric energy meter production test system in the present embodiment has full automatic ammeter error in dipping proofreading function.Electric energy meter production test system in the present embodiment, by the concept of " driver ", has increased the table platform " driver " of different manufacturers on market; The error collate program of system can be shown platform 8 by showing the control of platform driver, carries out error-tested.Concrete, the program that calibrates for error is first by showing the error in dipping of platform 8 reading power meters, and the information exchanges such as error in dipping, normalized current, voltage, power factor, phase angle are crossed to RS485 interface passes to electric energy meter.Electric energy meter is adjusted measuring parameter according to the error calculating parameter of input.By this close-loop control mode, automatically the error in dipping of electric energy meter is calibrated.
In the present embodiment, in workshop, be also provided with the platform 9 of having good luck, the platform 9 of having good luck is connected with electric energy meter and another testing workstation (N testing workstation 7N) respectively, the utilization test procedure of having good luck carries out the switching on test of relay, the test of having good luck, clock test, the test of RS485 interface communication and carrier communication test to electric energy meter, and test result is kept in database.In the present embodiment, be also provided with wireless router 6 in workshop, wireless router 6 accesses power line carrier LAN (Local Area Network).Can realize wireless connections by wireless router 6 like this.
In the present embodiment, backbone network system also comprises that the first web server 4, the first web servers 4 that access core network are connected with multiple web access ends by internet.In the present embodiment, in Fig. 1, drawn N web access end, be called the first access end 41 ..., N access end 4N.Backbone network system also comprises that the second web server 5, the second web servers 5 that access core network are connected with multiple workstations by corporate intranet.In the present embodiment, in Fig. 1, drawn N workstation, be called the first workstation 51 ..., N workstation 5N.Under the certain situation of the present embodiment, several workstations also can be additionally set, be directly articulated on data bus (access core network).In the present embodiment, backbone network system also comprises the network printer 3, and the network printer 3 also accesses core network, for printing.
Traditional electric energy meter production test system is in the production run of electric energy meter, and how rapidly electric energy meter being carried out to uniqueness, to identify this be a maximum difficult problem, and conventional is to stick bar coded sticker on the substrate of electric energy meter; Or at the inner prefabricated ID of the CPU of electric energy meter, when powering on, electric energy meter reads out.All there is obvious deficiency in these two kinds of methods.The method of sticked bar-code need to be sticked bar coded sticker at substrate before production, reads in bar code in each test post with barcode scanner, and the shortcoming of doing is like this that the intensity of the direct labor's operation time large, bar code recognition is long, at the bottom of production efficiency.In the time of the method reading power meters of the prefabricated electric energy meter numbering of CPU, need to power on to electric energy meter, electric energy meter numbering cannot be read in the post that cannot power on to electric energy meter at some, causes to use to be subject to limitation.In order to address these problems, the electric energy meter in the present embodiment is hung a RFID electronic tag in process of production on its substrate; Install on the surface of electric energy meter of table cover and posted the bar code that dispatches from the factory; Acquisition controller is by reading RFID electronic tag and the bar code that dispatches from the factory, in order to generation detection data and the factory testing data of electric energy meter are carried out to correspondence.
Specifically, electric energy meter, dropping into before assembling procedure production line, is hung a RFID label on substrate, and each RFID label has a unique tag number; Before the electric energy meter of every batch is produced, the batch information that Master Control Center can be produced this electric energy meter is set on the computer or acquisition controller of testing workstation, in the time that the RFID card reader in test post detects RFID label, test procedure (or acquisition controller) can, by unique ID of production batch and RFID tag number composition electric energy meter, carry out retrieval and the storage of electric energy meter test data with this unique ID.In the time that electric energy meter arrives " once packaging ", need to cover table cover, acquisition controller here dispatch from the factory bar code and the RFID label of reading power meters is carried out correspondence, and the production testing data in the information of dispatching from the factory and the factory of electric energy meter have just been mapped like this.In this post, RFID label is taken off, while production for the electric energy meter of follow-up batch.Because reading of RFID is convenient and swift, and need not power on to electric energy meter before using, greatly improve the production efficiency of electric energy meter.
Under the certain situation of the present embodiment, in the time will carrying out the burn-in test of electric energy meter, electric energy meter is put into high-temperature aging room, under the condition of high temperature, energising moves 24 hours continuously, acquisition controller gathered the data of electric energy meter automatically every one hour, and test result is stored in database.
In a word, in the present embodiment, according to predefined production technology, in the time that needs are adjusted production product type, the automatically servo programe of configuration testing workstation, adjusts tag end test program, reaches robotization and turn the effect of line, enhances productivity.Electric energy meter production test system in the present embodiment has adopted the first ZAP of function broadband power, add the technical parameter of bandwidth carrier, and on the basis of the Physical layer of broadband power line carrier, add power line carrier automatic network-building (route) agreement, electric power data signal conflict arbitration agreement, IP agreement, TCP/UDP agreement, make the ability of its composition power line carrier LAN (Local Area Network).Easily receive the noise problem of production equipment for power carrier signal, the electric energy meter production test system in the present embodiment mainly adopts two ways to solve, and the one, automatic route, communication data gets around the bypass of undesired signal automatically; The 2nd, the power supply of all production equipments is added to a trap, do not allow the power noise of production equipment to be sent on electrical network.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
