[0036] Refer to Figure 1 and Figure 2 , the measurement and control device of the rail vehicle ATC system includes an interface board module 201 and a main control module 103. The interface board module 201 includes an opto-coupled solid-state relay module 202 and an opto-isolated coupled sampling interface module 203. Both the opto-coupled solid-state relay module 202 and the opto-isolated coupled sampling interface module 203 are electrically connected to the main control module 103; the main control module 103 controls the opto-coupled solid-state relay module 202 to send a test signal to the rail vehicle ATC system, and the opto-isolated coupled sampling interface module 203 receives the feedback signal sent by the rail vehicle ATC system and transmits it to the main control module 103. The test signal and the feedback signal are transmitted through the interface board module 201, thereby realizing the isolation between the measurement and control device and the test tooling, which is safe and reliable.

[0037] It should be noted that the opto-coupled solid-state relay module 202 has a module with an opto-coupled circuit and a solid-state relay 211. The isolation between the input and output signal channels of the rail vehicle and the interface of the measurement tooling device is realized through the opto-coupled circuit; the solid-state relay 211 has the characteristics of all-solid-state electronic components and adopts a fully sealed encapsulation method with insulating waterproof materials, which is safer and more reliable. The opto-isolated coupled sampling interface module 203 is a module with an opto-coupled circuit and physical channels. The output signal of the rail vehicle ATC system is transmitted through the physical channels, and then coupled to an independent input and output loop through the opto-coupled circuit and transmitted to the main control module 103, realizing the isolation between the measurement and control device and the rail vehicle ATC system and protecting the safety of operators. Among them, the physical channels are two groups of input and output physical channels, and the lines with both input and output functions in the signal channels can be physically separated.

[0038] Refer to Figure 1 , Figure 2 and Figure 5, the above-mentioned measurement and control device further includes a change-over switch module 102. The interface board module 201 further includes a switch circuit module 204. The change-over switch module 102, the switch circuit module 204 and the opto-coupled solid state relay module 202 are electrically connected in sequence. The change-over switch module 102 can adjust the voltage of the output signal source of the ATC simulator and apply a suitable voltage according to different test devices; the switch circuit module 204 controls the signal flow of each signal channel. Multiple slide switches are configured for each channel to adjust the signal channel, and can control the signal transmission of different rail vehicle ATC systems.

[0039] It should be noted that the change-over switch module 102 is provided with multiple universal change-over switches, and each universal change-over switch can control the output voltage of multiple signal channels at the same time. Exemplarily, the change-over switch module 102 is provided with 8 universal change-over switches. Each universal change-over switch controls the output voltage of 8 signal channels at the same time. The first universal change-over switch is responsible for controlling the output voltage of channels 1-8, and the second universal change-over switch is responsible for controlling the output voltage of channels 2-16, and so on, in sequence, to achieve the voltage control of each channel; each universal change-over switch indicates the signal channel number and voltage level controlled by the switch. When the knob of the first universal change-over switch rotates from the "0 position" to the "24V" position, the output voltages of channels 1-8 are all 24V. When the knob of the second universal change-over switch rotates from the "0 position" to the "48V" position, the output voltages of channels 2-16 are all 48V. The above design can enable the device to be connected to different devices and has versatility.

[0040] It should also be noted that the multiple slide switches provided in the switch circuit module 204 can be three, or four, etc. The user controls the switch to adjust the signal flow, so as to be able to control different application scenarios.

It can not only display measurement and control information to the operator, but also display operation steps to guide manual operation for testing. In addition, for the testing of different ATC systems, there is no need to rework the tooling. Only the cables need to be modified, and the configuration of the general simulator can be directly modified on the display screen module 301 to achieve quick switching, which shortens the tooling design cycle for the commissioning of new project vehicles.
