Abstract：Aiming at the communication problems such as the complex internal composition of the emergency power supply device of electric locomotives,various operation functions,complicated control logic,long com-munication distance between modules,and strong electromagnetic interference within the device,a set of moni-toring system for the emergency power supply device of electric locomotives is designed by using the touch screen as the upper computer,DSP as the core controller,and combining the three communication and control methods of CAN,RS485,and Ethernet.It realizes the collection,transmission,display and early warning func-tions of power environment parameters.The hardware configuration of the system takes into account the pro-gram storage space,code running speed,number of I/O,electromagnetic interference and other factors,and de-velops the upper and lower computer programs for the management of the whole machine monitoring module respectively.And build a test platform in the actual use,high efficiency to complete the communication re-quirements.This system design can realize the native scheduling management of emergency power supply de-vice for electric locomotives,which is of great significance to improve the overall automation level.
