The invention provides a wheel diameter value modification management system and method, a secret key generator generates a temporary secret key according to train operation information, a DMI data processing module analyzes the temporary secret key to obtain the train operation information and verifies the train operation information, and after verification is passed, the wheel diameter value of a train can be checked or modified on the DMI of vehicle-mounted equipment. According to the system and the method, the defects that a traditional secret key is fixed and simple in verification are overcome, the permissions of operators are set more pertinently, drivers and conductors cannot modify the wheel diameter value, the operation safety is higher, the functions of displaying train information and checking or modifying the wheel diameter value of the train are integrated, operation is easy and efficient, and the workload of maintenance personnel is relieved.

    一种轮径值修改管理系统和方法,密钥生成器根据列车运行信息生成临时密钥,DMI数据处理模块解析所述临时密钥获得列车运行信息,校验所述列车运行信息,校验通过后,可以在车载设备人机界面DMI上查看或修改列车轮径值。本发明克服了传统密钥固定且简单校验的弱点,对操作人员权限设置更有针对性,司乘人员无法进行轮径值修改,操作安全性更高,将显示列车信息和查看或修改列车轮径值功能集成一体,操作简单高效,减轻了机务人员的工作负担。
