Auxiliary Power Supply System For The Simulator Device Of CHINA STANDRAD EMU

With the emergence of the Chinese standard EMU,this high-speed EMU,which is fully developed by China and has fully independent intellectual property rights,has been at the forefront of the world level,and its development speed is amazing to other countries.At the same time,the promotion and development of high-speed rail brings us the reality of talent shortage.For the training of high-speed railway technical personnel,the traditional oral presentation and the use of real vehicles waiting for maintenance can no longer meet the growing employment demand.Therefore,it is urgent to design a set of simulation training device specially used in technical personnel training.Compared with the traditional training methods,the use of simulation training device for training can effectively save training time,improve training efficiency,and greatly improve the operation safety.On the premise of ensuring the degree of simulation,Fu Xing EMU simulation training device can realize the simulation operation and debugging of EMU systems when employees are separated from the real train.In order to achieve the above purpose,the EMU simulation training device,on the premise of retaining the functionality of the original vehicle,simplifies the implementation of each system of EMU,integrates the components of each system,and realizes the functional requirements of different systems respectively.The auxiliary power supply system in the simulation training device adopts the modular design method according to the functional requirements and principle of the auxiliary power supply system of EMU.The auxiliary power supply system of EMU is divided into high voltage module,ACU module and charger and battery box module.The main circuit and control circuit are designed and implemented respectively.Using PLC＿Config to program ladder diagram and at the same time,MCGS configuration software is used to design human-machine interaction interface to realize the real-time monitoring of the running state.Finally,the whole system is debugged many times to ensure its safety and functional integrity.The auxiliary power supply system of Fu Xing EMU simulation training device highly simulates the main functions of the auxiliary power supply system of Fu Xing EMU.In the actual technical training,the use of the device can not only save costs,ensure the safety of operators,but also significantly improve the training efficiency.
