Exemplary, product requirements include, but are not limited to: subject, source, product/module, review and priority. The theme is a received test theme that needs to test the device under test, for example, the theme may be to replace a certain component of the device under test; the source is a test theme for any device to be tested, the source of the test theme can be a national standard for coming out of the platform or a requirement provided by a user, for example, the theme is to replace a certain part of the device to be tested, and the national standard issued by the country at a certain time for the part, namely the national standard to be met by the part; the product/module to which the test subject belongs is a functional module to which a place which needs to be improved belongs, for example, the subject is to replace a certain part of the device to be tested, the part is used for collecting the current amount in the test process, and then the module to which the part belongs is a collecting module; the review condition is that aiming at the received theme and source, the test manager reviews the feasibility of the test task aiming at the theme, for example, the theme is to replace a certain part of the device to be tested, the part is used for collecting the current amount in the test process, according to the national standard, the current to be passed by the part cannot be higher than 10A, but if the current to be passed by the replaced part is 12A after the part is replaced according to the theme, the test task is not executable; the priority is to different subjects in a test task, and the test manager sorts the different subjects according to the importance degree of the evaluation condition of the task, and when testing, the task with the front ranking is tested first.
For example, the target test environment is directed to a test task, which is a test task of a test device required in a test process, for example, the subject is to replace a certain part of the device under test, the part is used for collecting current during the test process, and a tester, a circuit meter and other devices are required during the test process.
In the technical scheme, the advantage of setting the test management platform is that test managers can design the test to be carried out on the device to be tested in advance according to the theme, the source, the affiliated module, the review condition and the priority aiming at the product requirement of the device to be tested in advance according to the received product requirement of the device to be tested, so that the required test equipment of the product requirement is determined, and the test accuracy and the test efficiency are improved. And the test management platform stores the test cases corresponding to the received product requirements of the device to be tested, so that a uniform case library is formed, and test management personnel and test execution personnel can conveniently inquire and maintain through a Web browser.
And the test execution platform 12 is in communication connection with the test management platform 11 and is used for calling a test case required by the device to be tested, receiving a test script required by the device to be tested, and controlling the tester 13 and the matrix switch 14 in the target test environment to test the device to be tested based on the test case and the test script.

For example, when the D1, D3, and D5 switches of the matrix switch are turned on, the three-phase voltage of the tester is connected to the device under test 1 to test the device under test 1, and similarly, when the D2, D4, and D6 switches are turned off, the three-phase voltage of the tester is connected to the device under test 2 to test the device under test 2. It should be noted that fig. 2 is only an exemplary diagram of a matrix switch, and in other embodiments, the matrix switch may include more than two groups of switches, so that more than two devices under test can be tested simultaneously.
In the technical scheme of the implementation, the matrix switch is arranged, because the existing single device to be tested needs a large amount of analog and digital input signals, but the number of channels of the analog and switching values of the single conventional tester is very limited, and a tester needs to test by repeatedly and manually replacing input and output signal lines.

For example, fig. 3 is a schematic diagram of switching current channels of a matrix switch, as shown in fig. 3, the matrix switch further includes at least two control switches K1 and K2, each of a set of switches D1, D3 and D5 in the matrix switch is electrically connected to an intermediate relay, each of another set of switches D2, D4 and D6 in the matrix switch is electrically connected to an intermediate relay, each intermediate relay has a coil J1, J2, J3, J4, J5 and J5 inside, each control switch is electrically connected to a coil corresponding to each set of switches in the intermediate relays, when the control switch K5 is closed, the coils J5, J5 and J5 electrically connected to the control switch K5 are energized, and further normally open contacts Q5, Q5 and Q5 of the intermediate relays including the coils J5, J5 and J5 are electrically connected to the switches D5, D5 and D5 of the matrix switch, and the control switch D5 of the matrix switch, D3 and D5 were closed.

Because the capacity of the existing relay is DC220V, 5A, after the electromagnetic intermediate relay is added, the coil working voltage of the electromagnetic relay is DC220V, when the two ends of the coil are connected with the DC220V voltage, the normally open contact on the intermediate relay is closed, and the normally open contact can pass 20A current, so that the relay which originally can only pass 5A current can be realized, and 20A current can be passed at present.
In the technical scheme of the implementation, the intermediate relay is arranged in the matrix switch, so that the purpose of converting the small current in the test process into the large current is realized, the current in the matrix switch can be kept at 20A for a long time in the whole test process, the automatic switching of a current channel is realized, and the requirement of large current test can be met.
