为提高下一代列车运行控制(简称列控)系统安全计算机的系统兼容性,首先对其结构进行简要分析,并对管理机制进行设计,建立了管理单元状态转移模型,同时以形式化验证工具对模型的正确性进行了验证。在此基础上对基于微控制单元(MCU,micro controller unit)的管理单元进行了软硬件的设计实现与测试。验证和测试结果表明,所设计的管理机制符合设计规范的要求,管理单元能够实现预期的状态转移功能。
In order to improve the system compatibility of the safety computer of the next generation train operation control system, first of all, the structure was analyzed and the management mechanism was designed, the state transition model of management unit was established, and the correctness of the model was verified by formal verification tools at the same time. Then the software and hardware which based on micro controller unit (MCU) were designed and implemented. The verification and test results show that the management mechanism design meets the design requirements, the management unit can achieve the expected state transfer function.
