Embodiment Construction
[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0036] figure 1 A logical block diagram of the fast mileage calculation system of the preferred embodiment of the present invention is shown. It includes a query request receiving unit 100 , a data extraction unit 200 , a mileage calculation unit 300 , a data output unit 500 , and a data center 400 connected in sequence.
[0037] The data center 400 stores the data including the license plate number, reporting time, and total mileage reported by the vehicle-mounted terminal regularly (for example, once a minute). The reported total mileage refers to the current total mileage of the vehicle, not th...

The invention relates to a method for calculating mileage quickly, which comprises the following steps: A, receiving report data from a vehicle-mounted terminal and updating a data center according to the report data; B, receiving a query request, wherein the query request carries a license plate number to be queried, and first and second time points to be queried, and the first time point is earlier than the second time point; C, querying the first total mileage and second total mileage of a license plate number which is to be queried and received by a data center, wherein the time point corresponding to the first total mileage is closest to the first time point, and the time point corresponding to the second total mileage is closest to the second time point; and acquiring the mileage L of the license plate number to be queried from the first time point to the second time point by subtracting the first total mileage from the second total mileage. The invention also provides a system for calculating the mileage quickly. According to the technical scheme of the invention, the mileage can be calculated quickly and accurately, the processing load of the data center is reduced, and the vehicle monitoring by traffic control department is facilitated.
Description
technical field [0001] The invention relates to a method and system for mileage calculation, in particular to a method and system for fast calculation of mileage. Background technique [0002] In the past, the mileage data of the vehicle was only obtained by reading the odometer of the vehicle to obtain the mileage data of the vehicle within a period of time. However, the odometers of many vehicles are broken, and the mileage data cannot be read accurately at all. Even on some relatively high-end cars, the mileage data can be adjusted artificially. Like this, it is just difficult for the management units of these vehicles to know the mileage of the vehicles accurately, thereby providing the possibility of abusing the vehicles to the users of the vehicles. [0003] Based on the above reasons, there is a method of using GPS to report the current GPS mileage value to the data center, and then accumulate the mileage data in the data center to obtain the total mileage of the veh...
