    • A method for quickly calculating mileage includes the steps: A, receiving report data from a vehicular terminal and updating data centre according to the report data; B, receiving an inquiry request which includes a vehicle number, a first time point which is earlier than a second time point and the second time point which are requested to inquire; C, inquiring the data centre to acquire a first total mileage value to which the time point that is proximate to the first time point corresponds and a second total mileage value to which the time point that is proximate to the second time point corresponds; D, obtaining a running mileage L from the first time point to the second time point by subtracting the first total mileage value from the second total mileage value. A system for quickly calculating mileage quickly is also proposed. The method and the system can calculate mileage quickly and accurately, reduce the processing burden of the data center, and facilitate the vehicle surveillance of the traffic department.
    • 一种快速计算里程的方法包括以下步骤:A,根据报告数据从车载终端接收报告数据和更新数据中心; B,接收包括车辆编号,比第二时间点早的第一时间点和请求查询的第二时间点的查询请求; C,询问数据中心获取与第一时间点接近的时间点对应的第一总里程值和接近第二时间点的时间点对应的第二总里程值; D,通过从第二总里程值减去第一总里程值,从第一时间点到第二时间点获得运行里程L。 还提出了快速计算里程的系统。 该方法和系统可以快速,准确地计算里程,减少数据中心的处理负担,便于交通部门的车辆监控。
