[0047] The switch button, indicator light and control interface unit are all arranged on a control panel, and the control panel is connected to each action model.

[0048] like Figure 2 As shown, the power supply unit converts 220V AC mains power into 24V DC working power to power the console and simulation workbench;

[0049] The power supply unit also transfers 220V AC mains power to the training workbench to supply power to the training workbench.

[0050] The 24V DC working power supply is an industrial-grade AC-to-DC power supply that supports an AC input voltage range of 85V to 264V. It has overvoltage, undervoltage, overload protection, and lightning surge protection functions, and can provide reliable working power for other components within an industrial-grade wide temperature range.

[0051] The control board is composed of a Freescale S21 single-chip microcomputer as a control processor, a switch button input control circuit, an indicator light output circuit and a control circuit of a control interface unit.

[0052] The button input circuit adopts optocoupler isolation circuit design, which can convert the 24V DC input level signal of the switch button into the 5V level signal required by the microcontroller.

[0055] The training workbench comprises:

[0056] A data interface unit, used to realize communication between the practical training workbench and the simulation workbench, the data interface unit is connected to the control interface unit;

The control board drives the brushless DC motor in the train model and controls the internal LED indicators of each device model on the vehicle body appearance to indicate the action devices in turn. When the train triggers the limit switch at the end of the track model, the motor inside the train model stops, completing the vehicle passing detection process. The control board sends the departure signal to the data processing unit through the control interface unit and the data interface unit. At the same time, the data display unit can present the vehicle passing record.
