Abstract: Based on the improved and optimized design idea of train control and management system (TCMS), control mode of TCMS and of traction system and braking system, and the functional integration of TCMS and passenger information system (PIS) are studied. A TCMS scheme with higher level of tram integration and better control is proposed. The scheme improves the starting process of the tram based on the collection of line slope realtime information; improves the execution and response of the tram braking by optimizing the braking force distribution strategy; improves the integration degree of the tram through the integration of certain functions of TCMS and PIS.
