Then, the insulation test signal enters the cage of the target controller through the D terminal corresponding to the D terminal test interface, the P terminal corresponding to the P terminal test interface and the network port corresponding to the network port test interface.

In the embodiment of the invention, the inside of the absolute limit tester comprises: the device comprises a strong current controller, a signal collector and a test signal generator, wherein the strong current controller is used for converting an input 220V alternating current power supply into a test power supply, namely a direct current strong current power supply, such as a DC500V power supply, and sending the strong current to the test signal generator; the test signal generator sends a negative polarity test strong current to the core wire to be tested after receiving the insulation test command: negative DC500V, sending a positive polarity test strong current to the remaining core wires as: a positive DC 500V; the signal collector is used for collecting current values between the core wire to be tested and other core wires, the resistance tester sends the sampled current values to the CPU, and the CPU judges whether the insulation performance between the cable wires meets the requirements or not by combining with criteria.

And secondly, the insulation tester samples the insulation test signal fed back by the cage of the target controller through the switching circuit interface, and takes the insulation test strong current sent to the target controller and the insulation test signal fed back by the target controller as test data.

Then, the resistance test signal enters the cage of the target controller through the D terminal corresponding to the D terminal test interface, the P terminal corresponding to the P terminal test interface, and the net port corresponding to the net port test interface.

In the embodiment of the invention, the resistance tester internally comprises: the weak current controller is used for connecting weak current of the weak current input port and sending the weak current to the test signal generator; after receiving the test command, the test signal generator sends a test signal to the core wire to be tested of the D terminal, the P terminal and the network port test terminal; the signal collector receives a test signal through the A terminal.

Exemplary 6, target controller line to line insulation Performance test

The insulation resistance between the cable wires in the cage of the target controller is not less than 25M omega, and a user can modify the resistance value of the insulation resistance in the criterion according to actual requirements.

When the line-to-line insulation resistance test is carried out, the insulation tester sends negative polarity strong current to the core wire to be tested of the OC cage through the D terminal test interface, the P terminal test interface and the net port test interface, positive polarity strong current is sent to other core wires in sequence, the insulation tester automatically tests the current value between the core wire to be tested and other core wires, the parallel current value sends CPUA and CPUB, the CPU carries out the calculation of the insulation resistance, when the resistance value is smaller than 25M omega 5, the poor insulation is judged, and an alarm prompt is given.

It should be noted that, in the embodiment of the present invention, for the line-to-line insulation test or the contact resistance test, as for the test of the target controller, the principle on which the criterion is adopted in the embodiment of the present invention is as follows:

for insulation test, the insulation tester sends DC500V test power supply to the core wire to be tested and other cables in sequence, when the insulation between the cage wires of the target controller is good, the signal collector should not collect current signals, or the current signals are smaller than the threshold set by the user (the tool judges according to the expected resistance set by the user and combining the sampling signals).

For the resistance test, the resistance value of the core wires with the corresponding relationship in examples 1 to 5 should be smaller than the resistance value set by the user, and when the resistance value is too large (the test signal received by the resistance tester is too small), the contact resistance is determined to be not in accordance with the requirement; when the resistance value is infinite (the resistance tester cannot receive the test signal), the problem of wire breakage is judged to exist; and when the core wire receiving end without the corresponding relation receives the test signal, judging that mixed wires exist.

During the insulation resistance test, as shown in fig. 2, the test interface (D terminal test interface, P terminal test interface, net port test interface) of the insulation tester is connected with the P terminal, D terminal, net port of the target controller cage; the P terminal, D terminal, and net port of the target controller cage are communicated with the a terminal (fig. 4) inside the cage through the internal wiring (part to be measured) of the target controller cage. Taking the core wire corresponding to a1 in fig. 3 as an example, it is required to measure whether the core wire meets the requirement of the insulation resistance between the core wire and any other wire in the target empty controller cage, during the test, the CPU sends a1 core wire test command to the insulation tester, the test signal generator of the insulation tester sends negative polarity test strong current to the D terminal a1 through the switching circuit, and simultaneously sends positive polarity test strong current to other core wires of the target controller cage in sequence, the signal collector samples the a1 terminal at any moment, when the insulation performance is poor, the signal collector can collect current signals, the signal collector sends sampling values to the CPU in real time, and the CPU determines the insulation resistance between the wires by combining the voltage and the sampled current values. And other core wires need to finish the test in turn according to the CPU instruction.

In the embodiment of the invention, the insulation resistance between the cables in the cage of the target controller is not less than 25 MOmega, a user can modify the resistance value of the insulation resistance in the criterion according to actual requirements, the resistance value of the cables in the cage of the target controller is less than 0.1 ohm, and the user can modify the resistance value of the resistance in the criterion according to the actual cable model.

Take the line-to-line insulation test as an example: when the strong current test signal is U, the signal collector of the insulation tester samples a signal A, and the CPU calculates the insulation resistance by combining the test signal and the sampling result.

Taking the contact resistance test as an example: the resistance tester self-resistance R, the contact resistance R, the test signal voltage U, the signal collector sampling signal A, and the CPU combines R, R, U, A to complete the calculation of the contact resistance.

In addition, the embodiment of the present invention further exemplifies a schematic structural diagram of a P-terminal test interface, as shown in fig. 6, the P-terminal is wired in a full-scale manner, and a user of the P-terminal model can freely select. The embodiment of the present invention also illustrates a schematic structural diagram of a socket test interface, as shown in fig. 7, in which an M12 interface is taken as an example, and a crystal head or other interfaces may also be used.

Finally, with reference to the verification tool shown in fig. 2, the embodiment of the present invention further exemplifies a test operation flow, which includes the following steps:

step 1, connecting a D terminal test interface, a P terminal test interface and a network port test interface of a checking tool with a P terminal, a D terminal and a network port of a target controller cage respectively;

step 2, connecting a terminal A test interface of the checking tool to the inner side of a cage of the target controller;

step 3, connecting the high-voltage external power and the low-voltage external power to the verification tool;

step 4, starting the system, operating the display screen to select the type of the target controller, clicking to start testing, and selecting manual testing or automatic traversal testing by an operator;

and 5, automatically giving a test result by the verification tool after the test is finished, storing the test result in a test report form, and copying and storing the test result by an operator.

Therefore, the target type of the target controller can be selected by operating the display screen, the central processing unit can search the preset criterion corresponding to the target type, and after the central processing unit sends out the insulation test instruction or the resistance test instruction, the switching circuit is switched to connect the insulation tester or the resistance tester into the test loop, so that the insulation test and the contact resistance test between the lines can be completed by utilizing different test loops.
