Research on ICCU Equipment for Urban Rail Transit Train Control Fusion

Based on the background of Tianjin Metro Line 5 project, a fusion ICCU equipment technology is proposed. The fused hardware is unified into an intelligent central control unit (ICCU host): As the core control unit, ICCU realizes the deep integration of TCMS and ATO functions. ICCU equipment with energy-saving intelligent algorithm was equipped on Tianjin Metro vehicles for the first time and tested on the main line of Tianjin Metro Line 5. According to the test results of the existing operation diagram at operation level three and operation level five, the comprehensive energy-saving optimization of a single train can achieve the goal of 10%. The problem solved by ICCU equipment is: through fusion, the interface between the signal system and the vehicle system is reduced, sensors are interchangeable, equipment is reduced, equipment reliability is improved, and maintenance costs are reduced. A detailed introduction to the fusion equipment of urban rail transit train control is given.
