In view of the problem that the existing high speed maglev operation control system in China can not meet the complex operation requirements of long-distance trunk lines, this paper aims at automatic tracking operation of long-distance trunk lines, meeting long-distance multi-zone environment and adapting to safe operation of trains under complex geographical and climatic conditions. By studying operation scenarios of maglev system and identifying potential safety hazards, a set of high speed maglev operation control system with long stator is developed to adapt to the complex application environment in China, which adopts the independent and controllable safety computer platform of CRRC, realizes functions of high speed maglev train speed curve monitoring, automatic train operation, train protection, traction cut-off, turnout protection and route protection. There are 645 integrated test cases through laboratory hardware-in-loop simulation, with a pass rate of 89%; 59 field test cases on the test line, and 2 cases not executed due to the conditions, with a pass rate of 97%. The results show that the operation control system designed in this paper has complete interfaces and functions, and can meet the control requirements of 600 km/h maglev train. |
