[0025] The bottom platform 2, the middle platform 3 and the top platform 4 have the same structure, and the edges of the bottom platform 2, the middle platform 3 and the top platform 4 are all provided with enclosing edges.

[0026] The working principle of the utility model is as follows, as shown in Figure 1 The low-voltage manager 5 converts 230VAC into 24VDC and 15VDC, is responsible for power supply for the signal conversion panel 12, the main control simulation machine 7, the optical-electricity converter 10, the communication switch 6, the logic state switch 8, the distributed controller 11 and the control unit 9 on the test vehicle, and adopts a 6-way independent double-channel miniature circuit breaker control.

[0027] Since the physical interface of the simulation machine I / O signal generally adopts DB37 specification, the signal conversion panel 12 of the device is used to extract the interface signal of DB37 specification and connect to the photoelectric converter 10 and the distributed controller 11, so as to realize the interactive mapping of the simulation signal.
