It can realize parameter acquisition and fault diagnosis of electrical equipment used in rail transit vehi-cles by means of a remote mode and realize rapid maintenance, which is of great significance for safe operation of ur-ban rail transit vehicles. To this end,it shall develop an on-board terminal data transmission unit for the remote diag-nosis system of electrical equipment used in urban rail vehicles,thus realizing functions including docking of traincommunication ＆ control networks,remote acquisition of electrical equipment failure information on vehicles,etc.This article introduces the HW ＆ SW design for the data transmission unit. By testing the remote diagnosis system,it shows that the data transmission unit can monitor the operating conditions of various electrical equipment used inurban rail transit vehicles in real time. It extracts any information on the running status of electrical equipment fromthe network,thus realizing the running status data transmission design requirement for electrical equipment.
