Method and system for quickly calculating mileage

摘要

A method for quickly calculating mileage includes the steps: A, receiving report data from a vehicular terminal and updating data center 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 center 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.

1. A method for quickly calculating mileage, comprising:
A. receiving report data from a vehicular terminal and updating a data center (400) according to the report data; wherein the report data includes a vehicle number, a report time and a total mileage value of a vehicle corresponding to the vehicle number during the report time; B. receiving an inquiry request which includes the vehicle number, a first time point and a second time point which are requested to inquire, wherein the first time point is earlier than the second time point; C. screening out a first data set having a report time within a range from the first time point to the second time point from the data center (400), wherein the first data set includes the vehicle number, the report time and the total mileage value; D. sorting the first data set obtained in the step C in a descending order in accordance with the report time, and extracting the first data of the sorted first data set in the descending order for respective vehicle number which is requested to inquire to obtain a second data set; E. sorting the first data set obtained in the step C in an ascending order in accordance with the report time, and extracting a first data of the sorted first data set in the ascending order for the respective vehicle number which is requested to inquire to obtain a third data set; F. screening and filtering the third data set obtained in the step E and selecting a first total mileage value for the vehicle number which is requested to inquire, and screening and filtering the second data set obtained in the step D and selecting a second total mileage value for the vehicle number which is requested to inquire, wherein a time point to which the first total mileage value corresponds is larger than or equal to and further proximate to the first time point, and a time point to which the second total mileage value corresponds is smaller than or equal to and further proximate to the second time point; G. obtaining a running mileage L for the vehicle number requested to inquire from the first time point to the second time point by subtracting the first total mileage value from the second total mileage value; and H. returning the running mileage L to a user requesting to inquire.
