The invention relates to a method for uploading the positioning data of vehicles, which comprises the following steps of: acquiring effective
global position system (GPS) data as historical positioning data; after waiting for one acquisition interval, acquiring the
GPS data, detecting the state of the vehicles if
GPS positioning succeeds, and if the vehicles are in the motion state, calculating the average displacement M of the vehicles at each acquisition interval by taking distance between the current
GPS data point and a historical positioning
data point as a numerator and the acquisition interval between the current
GPS data point and the historical positioning
data point as a denominator; when the average displacement M is more than the upper limit of the displacement, discarding thecurrent GPS data, and otherwise, taking the current GPS data as the historical positioning data; if the vehicles are in the static state, discarding the current GPS data; and repeating the process ofacquiring the GPS data until the uploading time, and uploading the historical positioning data serving as the current positioning data to a monitoring center. By the method, the problem of poor
data reliability during the uploading of the position information, acquired directly in real time within the uploading time, of the vehicles is solved.
