S70: and determining whether the line connection is correct according to the target image. Executing step S30 when the line connection is correct; otherwise, an alarm message may be sent.
If the line connection is incorrect, the test is also continued, and the result of the test is likely to be erroneous. Therefore, through the arrangement of the steps S60 and S70, the situation of error connection of the line can be timely found, the test is avoided under the condition of error connection, and the accuracy of the test result is improved.
In some embodiments, step S70 may obtain a pre-stored line connection image corresponding to the target test module, and then input the target image and the line connection image into a pre-trained network model, so as to obtain a result of whether the lines output by the network model are consistent.
The prestored line connection image is an image of a correct line corresponding to the target test module, so if the output result of the network model is consistent, the test line connection is correct.
In other embodiments, step S70 may identify the marks set at the interfaces and the port marks at the two ends of the connection line from the target image and the line connection image, and then determine whether the identification result corresponds to the interface connection relationship corresponding to the pre-stored target test program module, and if so, determine that the line connection is correct.

The marks may be, for example, triangles, pentads, squares, etc., or may be red marks, yellow marks, blue marks, etc.
The method for automatically identifying whether the wiring is correct can be used for identifying whether the cable connection among the test instrument, the test module, the industrial personal computer and the test object is correct or not; the wiring relation which cannot be automatically identified can be confirmed by a tester, and after the tester confirms, a conclusion of whether the wiring is correct is input through the operation of the industrial personal computer.

There may be a plurality of association relationships. The interface position may be a relative positional relationship or a position under a target coordinate system.
For example, a first interface on the test instrument is located at the M point, a second interface on the test module is located at the N point, and an association relationship is stored between the M point and the N point in advance, so that the manipulator can connect the first interface and the second interface by using a connecting wire.
In some cases, the above S80 may also acquire the interface mark of the wiring object, and then control the robot to automatically wire between the interfaces having the same interface mark. The association relationship may be plural. The marks may be, for example, triangles, pentads, squares, etc., or may be red marks, yellow marks, blue marks, etc.
For example, the third interface on the test instrument is a triangle mark, and the fourth interface on the test module is also a triangle mark, so that the manipulator can connect the third interface and the fourth interface by using a connecting wire.
The automatic wiring method can be used for automatically wiring every two of the test instrument, the test module, the industrial personal computer and the test object; the automatic wiring can be performed between the two specified components, and the part incapable of automatic wiring can be wired by a tester.
Further, the automated test system may further comprise a wire storage device for storing the connection wires. The connection line here is a wire, which may be in the form of a wire harness. There may be more than one type of connection line, different types of connection lines often have different connection interfaces, or different lengths of lines.
Correspondingly, the automatic test method can control the manipulator to automatically take the connecting wire of the target type from the wire storage device. This is possible for those skilled in the art, and the specific implementation of the connection line is not described in detail in this specification. Through the arrangement, the automatic test system can automatically take the connecting wire, automatically connect the wire, automatically judge whether the wire is correct, automatically start the test, automatically read the test result and automatically generate the test report, thereby realizing the high automation of the test process.
In some embodiments, the test report may be stored in a specified storage service of the test institution, and then step S50 may obtain the storage address of the test report, generate the second identification code from the storage address, and set the second identification code on the object to be tested, for example, print (e.g., laser print) the identification code on the surface of the object to be tested, or print the second identification code on a paper label, and post the label on the surface of the object to be tested.
In other embodiments, the first identification code may correspond to a specified storage space on a specified server into which content may be written. Then, the step S50 may first obtain the storage address of the test report, then scan the first identification code posted on the tested object by the code scanning gun, and write the storage address of the test report or the test report into the target storage space corresponding to the first identification code.
Prior to a write operation, the test authority should acquire write rights for the target storage space. While the write rights of the target storage space are usually mastered at the manufacturer of the object under test.
