Embodiment Construction

[0031] The method for real-time statistics of vehicle mileage of the present invention comprises the following steps:

[0032] A. The vehicle terminal is powered on;

[0033] B. GPS valid data determination;

[0034] C. Vehicle and platform networking;

[0035] D. Packet sending;

[0036] E. Background database establishment.

[0037] The determination of GPS valid data includes the following steps:

[0038] a. Read the total mileage data in the Flash memory of the vehicle terminal;

[0039] b. Determine whether the GPS positioning information is valid; if it is valid, go to the next step; if it is invalid, discard the unreasonable data;

[0040] c. Determine whether to remove the drift; if yes, go to the next step; if no, discard the unreasonable data;

[0041] d. Determine whether it is the first valid data; if yes, go back to step b; if no, go to the next step;

[0042] e. Whether the calculation results of the two data before and after are within the specified range...

Abstract

The invention relates to a method for measuring a running distance of a vehicle, in particular to a method for counting traveled mileage of an automobile in real time. The method for counting the traveled mileage of the automobile in real time comprises the following steps of: powering up a vehicular terminal; determining effective data of a global positioning system (GPS); networking an automobile table; transmitting a data packet; and building a background database. By the method for counting the traveled mileage of the automobile, the accumulated traveled mileage of the automobile can be well counted by GPS receiving equipment and a microcomputer which are equipped on the automobile, so the method is simple and feasible, and low in cost. In the method, the accumulated traveled mileage is backed up by a nonvolatile memory, so the damage prevention property is good, the data is real and reliable, and an electronic milometer or a mechanical milometer can be totally saved.

Description

technical field [0001] The invention relates to a method for measuring the distance traveled by a vehicle on the ground, in particular to a method for real-time statistics of the mileage of the vehicle. Background technique [0002] At present, most vehicles have a mechanical odometer to measure the number of revolutions of the wheels and calculate the accumulated mileage accordingly. The digital disc of the odometer is installed on the dashboard of the vehicle to display the value of the accumulated mileage, which is very easy After being disassembled, the digital disk is tampered with the value of the accumulated mileage, so that the vehicle supervision department cannot accurately know the actual accumulated mileage data of the vehicle. With the rapid development of the transportation and logistics industry in various countries, higher requirements are put forward for the safety monitoring and management of vehicle driving and understanding of real-time status. Different...
