The automatic testing equipment of multi-channel selector and method thereof
Technical field
The present invention relates to the automatic testing equipment and the method thereof of a kind of automatic testing equipment and method thereof, particularly a kind of multi-channel selector.
Background technology
Present stage, aspect debugging and test channel selector switch, domestic most repeater equipment manufacturer, all be to adopt the most original manual adjusting, measuring method, need operating personnel manually to be provided with and operating instrument, and go to see displayed value and read-write on the instrument by naked eyes, come to determine whether the channel selector that institute debugs and test is qualified, and will constantly regulate and make the channel selector requirement that touches the mark.Operation and detection step are numerous and diverse, and amount of test data is huge, the Analysis and Identification difficulty.In debugging and test process, very easily cause certain sum of errors mistake, production and detection efficiency are extremely low, debug about 2~3 of output for each person every day.
Summary of the invention
The present invention the invention provides a kind of automatic testing equipment and method thereof of efficient, accurate multi-channel selector in order to overcome above-mentioned the deficiencies in the prior art.
The technical solution adopted for the present invention to solve the technical problems is: the automatic testing equipment that a kind of multi-channel selector is provided, it comprises CPU, channel selector debugging plate, testing tool device and channel selector, wherein said CPU links to each other with this channel selector debugging plate and testing tool device respectively, and described channel selector links to each other with this channel selector debugging plate and testing tool device respectively.
The scheme that the present invention solves further technical matters is: described CPU links to each other with the testing tool device by USB/GPIB patchcord or LAN line.
The scheme that the present invention solves further technical matters is: described USB/GPIB patchcord or LAN line link to each other with USB or the LAN interface of CPU.
The scheme that the present invention solves further technical matters is: described channel selector debugging plate is connected the com interface of this CPU.
The scheme that the present invention solves further technical matters is: described CPU debugs between the plate with channel selector and links to each other by a RS485/RS232 breakout box.
The scheme that the present invention solves further technical matters is: CPU carries out data interaction and control with testing tool device and channel selector respectively.
The scheme that the present invention solves further technical matters is: be provided with or obtain the parameter of testing tool device and the parameter of adjustment channel selector by CPU.
The scheme that the present invention solves further technical matters is: this automatic testing equipment is tested the selector switch of four channels simultaneously automatically.
The scheme that the present invention solves further technical matters is: a kind of automatic test approach of multi-channel selector, it may further comprise the steps: the automatic testing equipment that a kind of multi-channel selector is provided, it comprises CPU, channel selector debugging plate, testing tool device and channel selector; Send setting or query statement by CPU to testing tool device and channel selector; Data message and pre-configured analysis that CPU obtains testing tool device and channel selector; Draw the test result of channel selector by the analysis result in last step.
The scheme that the present invention solves further technical matters is: if test can't be passed through, the tester can adjust channel selector again, and above repeatedly step finally reaches the requirement of qualified index.
Compared to prior art, the automatic testing equipment of multi-channel selector of the present invention had changed in the past the mode of operational testing apparatus and debugging channel selector by hand, but the mode that adopts the whole-process automatic control debugging and test, can increase work efficiency widely, operating personnel only need be by the upper computer software in the computer, be provided with and operational testing apparatus and channel selector, simplified numerous and diverse testing procedure widely, accelerated the speed of debugging with test, data amount of filling in and artificial data analysis have been reduced, thereby improved production and detection efficiency widely, reduced error rate and error rate.

Embodiment
Following content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
As shown in Figure 1, the automatic testing equipment of multi-channel selector of the present invention comprises CPU, channel selector debugging plate, testing tool device and channel selector.Wherein said CPU links to each other with this channel selector debugging plate and testing tool device respectively, and described channel selector links to each other with this channel selector debugging plate and testing tool device respectively.
Described CPU links to each other with the testing tool device by USB/GPIB patchcord or LAN line, and described USB/GPIB patchcord or LAN line link to each other with USB or the LAN interface of CPU.Described channel selector debugging plate is connected on the com interface of this CPU, and described CPU debugs between the plate with channel selector and links to each other by a RS485/RS232 breakout box.
As shown in Figure 2, after above-mentioned structure is built successfully,, can carry out data interaction and control with testing tool device and channel selector respectively by the control of CPU; In the operation interface of test automatically, can send and be provided with and query statement, the parameter of going to be provided with or to obtain the parameter of testing tool device and adjusting channel selector, can go to adjust, be provided with the correlation parameter and the index of channel selector and testing tool device automatically, and under the special parameter environmental baseline, CPU directly obtains desired data message from channel selector and testing tool device.For all information that get access to, analyze automatically by the algorithm of configured in advance, notify the test result of tester's channel selector.If test can't be passed through, the tester can adjust channel selector again, and above repeatedly step finally reaches the requirement of qualified index.This device can be tested the selector switch of four channels at most simultaneously automatically.
The automatic testing equipment of multi-channel selector of the present invention had changed in the past the mode of operational testing apparatus and debugging channel selector by hand, but the mode that adopts the whole-process automatic control debugging and test, can increase work efficiency widely, operating personnel only need be by the upper computer software in the computer, be provided with and operational testing apparatus and channel selector, simplified numerous and diverse testing procedure widely, accelerated the speed of debugging with test, data amount of filling in and artificial data analysis have been reduced, thereby improved production and detection efficiency widely, reduced error rate and error rate.
