Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic test data input/output device that improves the efficiency of test work performed by an automatic test machine.

For example, it is well known that continuity tests of wiring of various devices constituting an automatic exchange are automatically performed by an automatic testing machine in order to improve test efficiency. In this type of automatic testing machine, test procedures are prepared in advance as test data corresponding to the type of device under test, and the required test data is input into the automatic testing machine at the time of testing to execute the required test. let

In order to improve the efficiency of test work using automatic testing machines, it is necessary not only to automate the execution stage of the test work, but also to streamline each work from the test data creation and input stage to the test result analysis stage. This is strongly requested.

[Conventional technology]

FIG. 2 is a diagram showing an example of a conventional automatic test system.

In FIG. 2, the test data input to the automatic testing machine 1 is coded in advance by the tester on a coding sheet corresponding to the device under test 2, and then the paper tape 4 is inserted by operating the G tape punching machine 3. The test data is created, read by the Gion tape reader 5, inputted into an automatic testing machine, and debugged the test data.

For defects in the test data detected as a result of debugging, the holes in the tape 4 are corrected manually. The paper tape 4 whose normality has been confirmed as a result of debugging is duplicated and used for actual test work. In addition, the contents of the perforations of the normal tape 4 are printed out and stored.

The automatic testing machine 1 receives and analyzes the test data input from the Gion tape reader 5 using the control unit (CTL) 11, and transmits the energizing unit (DV) 12 and the detection unit (DT) 13 to the test data of the device under test 2. After setting the decoders (DC) 14 and 15 so that they are connected to the points specified by
2 to the device under test 2 specified by the test data.
is applied to the detection unit 13, and it is determined whether the signal specified by the test data is detected by the detection unit 13. - When the test operation for a set of test data is completed, automatic testing of other parts is executed based on the next set of test data.

If an abnormality is detected as a result of the test, the abnormality detection position is displayed using the output terminal numbers of the decoders 14 and 15 or the setting codes of the decoders 14 and 15 included in the test data.

The tester selects the device under test 2 from the displayed output terminal number etc.
The above physical location is searched using, for example, a conversion table prepared in advance.

[Problem that the invention seeks to solve]

As is clear from the above description, in conventional automatic test systems, a lot of effort and time are spent on creating test data, such as coding and reworking the tape 4 during debugging.

Furthermore, since the test data is input into the automatic testing machine 1 using the tape 4, it takes time and effort to input the data, which may increase the test time.

Furthermore, abnormalities in the test results are displayed in a format similar to the structure of the automatic tester 1, such as the output terminal numbers of the decoders 14 and 15 of the automatic tester 1, so in order to repair the device under test 2, It is necessary to convert each location to a physical position on the device under test 2 using a conversion table or the like, which may lead to an increase in testing man-hours and testing time.

[Means for solving problems]

The present invention solves the above problems by taking the following measures.

That is, in the present invention, an automatic test data input/output device having the following functions is attached to an automatic test machine that automatically performs a continuity test or the like of a device under test.

Test data for controlling the test operation of the automatic testing machine is input from the keyboard, and the manually entered test data is displayed on the display screen and stored in the storage device.

When an automatic testing device is used to perform a test, the accumulated test data is manually input to the automatic testing device according to a predetermined procedure.

Based on the input test data, abnormal position information output by the automatic testing machine that tested the device under test is converted into a physical location on the device under test and displayed on the display.

Furthermore, the test results output by the automatic testing machine are printed out.

[Effect]

That is, according to the present invention, the creation and input of test data and the output of test results are greatly simplified, and the test results are printed and recorded, thereby greatly simplifying the test work.

When transmitted, the processor (CPU)
64 refers to the conversion table stored in the memory (MEM) 65, converts the transmitted abnormal location information into physical position information of the device under test 2, and displays it on the screen of the display 62. Based on the displayed results, the tester can easily detect the repaired parts of the device under test 2.

Furthermore, the automatic test data input/output device 6 sends the test results for abnormalities and other areas transmitted from the automatic tester 1 to a printer (Printer).
