In the invention, the test board can be automatically controlled to adjust output parameter to test the electric instrument and batching testing can be realized; as a result, early failure period of products can be effectively reduced, debugging efficiency can be improved and labor resource costs can be reduced.
Description
Technical field
The present invention relates to the automatic testing method of the correlative technology field of electric instrument, particularly a kind of electric instrument.
Background technology
The electric instrument of present most of manufacturer production all adopts single-chip microcomputer as disposal system, realize functions such as sampling, data processing, keyboard demonstration, communications, general application is to adopt host computer (other systems such as PC or PLC) by certain passage such as serial ports, TCP/IP etc. data to be sent in the single-chip microcomputer, communication protocol according to a preconcerted arrangement, register in this sheet is carried out read-write operation, revise the purpose that data value carries out the adjustment of data and debugging to reach.
Generally when this method of employing is carried out data communication, be that the debugging software that adopts producer to write voluntarily carries out read-write operation to this relevant electric measuring instrument, the data of reading and the data of test board compare, then debug this instrument again, can only debug an instrument at every turn, and require the commissioning staff in the process of debugging, constantly to compare with test board, to obtain measurement data accurately, the false judgment that this debud mode causes easily, require the verification debugging as a large amount of electric measuring instruments, then usually will wait for for a long time.
Summary of the invention
The invention provides a kind of automatic testing method of electric instrument,, carry out the technical matters that the electric instrument debugging needs manual debugging to solve in the prior art.
The technical solution used in the present invention is as follows:
A kind of automatic testing method of electric instrument, test platform is connected with a plurality of electric instruments with test board, and described method adopts multithreading to realize that described multithreading comprises by test platform, test board communication thread and electric instrument communication thread, two thread synchronization operations:
The test board communication thread is used to handle and the parameter reading and writing of test board and the read-write of proof test value automatically;
The electric instrument communication thread is used to handle and the communicating by letter and the verification protocol transmission of electric instrument.
The application that above-mentioned test platform is general is to adopt host computer, as other systems such as PC or Programmable Logic Controllers.
As a kind of preferred version, the electric instrument communication thread of described method adopts the mode of formation to deposit the parameter of electric instrument.
As further preferred version, the step of described method is as follows:
(31) test platform and test board establish a communications link, if set up successfully, and execution in step (32) then, otherwise withdraw from;
(32) test platform and electric instrument establish a communications link, if set up successfully, and execution in step (33) then, otherwise withdraw from;
(33) carry out debugging checking procedure automatically.
As further preferred version again, the step of described automatic debugging checking procedure is as follows:
(41) the electric instrument communication thread read electric instrument instrument to be measured tuning parameter and parameter is placed in the formation;
(42) read test platform data (as input signal data, as electric current, voltage, frequency etc.) and pass to the electric instrument communication thread in the test board communication thread;
(43) action of debugging is judged and made to the electric instrument communication thread automatically by communicating with electric instrument;
(44) the electric instrument communication thread enters in the next formation, takes out the parameter in the debugging formation, carries out loop test, finish up to an electric instrument debugging,, then connect next instrument and test if also have next instrument, and execution in step (41), otherwise withdraw from.
As further preferred version:
In the described step (31), when test platform can't connect with test board, alarm prompt then;
In the described step (32), when test platform can't connect with electric instrument, alarm prompt then.
The present invention can control test board adjusting output parameter automatically electric instrument is carried out verification, and verification in batch, has reduced the debug time of producing product effectively, has improved debugging efficiency, has reduced the cost of human resources.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in more detail.
Present embodiment adopts test platform to be connected with a plurality of electric instruments with test board.The debugging flow process before testing electric instrument, is connected test board earlier as shown in Figure 1 with test platform, link with this equipment by one tunnel communication, makes it can control test board, convenient later data manipulation, as read and write data, revise parameter etc.Definite test board connect and communicate by letter errorless after, should be being connected with test platform after the electric instrument networking to be measured, as shown in Figure 2, the dual communication of test platform employing so far is connected with electric instrument with test board and finishes.
Above equipment connect finish after, start special-purpose debugging software, utilize the function of initializing of this software, the ruuning situation of self diagnosis equipment can not successfully connect or connect wrong as discovering device in detection, then give prompt alarm.
As shown in Figure 3, before entering automatic debugging checking procedure, software starts and the test board communication thread earlier, read the tuning parameter of the instrument to be measured of electric instrument then, and the data transfer that will read from the test board communication thread is given in the electric instrument communication thread, so far, the action of debugging can be judged and make to software automatically, finish this debugging task then, and enter in the next formation, take out the parameter in the debugging formation, carry out loop test, finish up to an electric instrument debugging, connect next instrument then and test, repeat above process.
Communication thread is by reading the data of register in the electric instrument, can obtain and whether debug and parameters such as debugging progress, judge by the real time data that reads in the data obtained in the input signal from the test board communication thread and the electric instrument, whether consistent, whether tuning parameter meets, as meet then interrupt test platform communication thread, carry out the tuning parameter register read write operation of this electric instrument.And then start communication thread and obtain another level signal data, and carry out the verification of next tuning parameter.
