Data Acquisition and Transmission System for Tramcar Powered by Hydrogen Cell

Aimed at the limited recording capability of critical vehicle data of existent recorder devices on tramcars, this paper studies the CANopen network, the design and development of an onboard data recorder suitable for hydrogen cell power tramcars. The recorder is able to record all the data over vehicle bus, and transmit in distance pre-configured critical data and malfunction information in real time. The ground server receives this information and performs data mining, thus realizing automated diagnostics of tramcars.
