VOBC (vehicle on-board controller) simulation demonstration system

The invention provides a VOBC (vehicle on-board controller) simulation demonstration system which comprises a navigation bridge, a navigation bridge driving acquisition plug-in box, a navigation bridge simulator and a VOBC simulator. Vehicle control operation state information of the navigation bridge is acquired by the navigation bridge simulator via the navigation bridge driving acquisition plug-in box and is transmitted to the VOBC simulator; the vehicle control operation state information acquired by the navigation bridge simulator is received by the VOBC simulator, corresponding processing is carried out according to the vehicle control operation state information, and traction brake control information is generated and is fed to the navigation bridge simulator, so that corresponding operation can be carried out by the navigation bridge according to the traction brake control information, and train simulation demonstration can be implemented. The VOBC simulation demonstration system has the advantages that the equipment constructing and debugging time can be saved, the VOBC simulation demonstration system can be linked with the real navigation bridge, and real navigation scenes can be displayed.
