Description

technical field [0001] The embodiment of the present application relates to the field of electronic circuits, in particular to a simulation device and operation method of a four-wire DC switch machine. Background technique [0002] With the development of high-speed railway technology, as well as the design, development and engineering application of interlocking equipment, hardware testing, software testing, product integration testing, engineering application testing, etc. Functional and performance tests to verify the correctness of the operation of the switch control circuit and interlocking equipment, and to check whether the operation of the switch and the connection of the display circuit are correct, whether the action meets the operating expectations, and whether the function is normal. A four-wire DC switch machine is required during the test. [0003] Due to the high power and stable performance of the four-wire DC switch machine, it has been widely used in high-...

AI Technical Summary

Problems solved by technology

[0004] 1. A single device occupies a large area and requires a large laboratory for placement;

[0005] 2. A single device is heavy and inconvenient to move;

[0006] 3. The cost of a single switch machine is high and the investment is large;

[0007] 4. Multi-machine traction requires 5, 9 or even more switch machines, and requires a larger test site for placing switch machine equipment;

[0008] Due to the limitation of the four-wire DC switch machine, it is often impossible to fully and fully test the control circuit of the four-wire DC switch machine in the product design and development stage, product integration test stage, and engineering application test stage
