[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0020] Figure 1 It is a block diagram of a test system according to an embodiment of the present application.

[0021] AsFigure 1 As shown in the figure, the test system provided in this embodiment is used to test the WBS-C inter-station security information transmission system to be tested to determine whether its performance meets the standards. The WBS-C inter-station security information transmission system is set in the corresponding cabinet, so it can also be simply referred to as the WBS-C cabinet 100. The test system includes a host computer 10, a test main station 20, and multiple transfer cables 30.

[0022] The above-mentioned host computer is a PC, laptop, server, or cloud platform configured with the test software. It is connected to the test main station and is used to send test instructions to the test main station based on the user's operation; the host computer is connected to the test main station through a serial cable.

[0023] The test main station is connected to the WBS-C inter-station security information transmission system to be tested through multiple transfer cables. After receiving the test instructions sent by the host computer, it sends test signals to the WBS-C inter-station security information transmission system through the transfer cables, receives the test data fed back by the WBS-C inter-station security information transmission system based on the test signals, and forwards the test data to the host computer.

[0024] After receiving the above-mentioned test data, the host computer analyzes and processes the test data based on the test software to obtain the test results. In addition, the test results can also be displayed based on actual requirements, and the test results can be recorded together or separately. Thus, the test of the WBS-C cabinet is realized.

[0025] The multiple transfer cables include self-check cables, power cables, and signal cables. The test main station includes at least one CPU board connected to the host computer, and also includes multiple output boards and multiple input boards connected to the CPU board, as Figure 2 shown. The output boards are respectively connected to the switch box I system, the switch box, and the switch box II system of the WBS-C inter-station security information transmission system. The input boards are respectively connected to the group box I system and the group box II system of the WBS-C inter-station security information transmission system.

[0026] It can be seen from the above technical solutions that this embodiment provides a test system for a WBS-C inter-station security information transmission system. The test system includes a host computer, a test main station, and multiple transfer cables. The host computer is connected to the test main station and is used to send test instructions to the test main station based on the user's operation; the test main station sends test signals to the WBS-C inter-station security information transmission system to be tested through the transfer cables, receives the test data fed back by the WBS-C inter-station security information transmission system based on the test signals, and forwards the test data to the host computer; the host computer is also used to analyze and process the test data based on the test software to obtain the test results. Users can determine whether its functions meet the standards through the test results.

[0027] The software part of this application consists of the host computer software and the slave computer software. The host computer software is installed in the host computer. Users can issue test commands through the human-machine interface, display test data in real time, generate test reports, save test records and view historical test records. The slave computer software is burned into the CPU board of the test main station. Its function is to control the CMOS transistor to complete the on-off of the test path, collect the test data back, and judge the on-off and whether there is wire mixing of the cable.

[0028] During the test, only one port is wired and tested each time. After the test is completed, the next port is replaced and the test continues. The test process is as Figure 3 shown.

[0029] According to the interface of the WBS-C type cabinet plug wiring, it can be classified according to its connectors as shown in the following table, a total of 2 types. One transfer test interface is used for testing according to the interface of each connector type in the following table. A total of 14 interface plugs are required.

[0030]

[0031] The host computer sends a control signal to the test main station, and one of the CMOS transistors on the output board 1 is turned on to output a detection signal. This signal needs to be traversed with the signals corresponding to all the cables in the input board B1 to judge whether it is conductive or there is wire mixing. Similarly, the other input boards and output boards work on the same principle.

[0032] Each input board or output board has 2 ports, and each port has 32 port positions. According to the in-cabinet schematic diagram of the WBS-C type cabinet, one end connector of the cable connection module is defined as the detection signal input port; the other end of the cable connection is defined as the detection signal output port. The plug interface wiring test distributes the ports of the input and output boards as shown in the following table:
