Abstract: Train control center (TCC) is an important equipment in railway signal systems, its transmission reliability must be ensured in the process of CAN bus design. Based on the analysis of factors affecting the reliable transmission of CAN bus such as elements, cables and temperature, the paper puts forward that the factors affecting the CAN time delay are elements and high temperature, for providing reference for the design in terms of CAN time delay and the selection of CAN cables.
