Embodiment Construction
[0032] The present invention will be further described below through specific embodiments.
[0033] An error correction method for automatic vehicle station reporting is used to identify error stations, determine the real station location, and then automatically correct the route file. Pre-number all stations in the route file of the station reporting system in sequence, preset n to 3 and L to 30 meters. The remaining steps are as follows:
[0034] 1) When the vehicle is in the normal operating frequency, collect the operating status of the station reporting system in real time, and mark the station with the number of missed reports exceeding n as the error station, refer to figure 1 ,details as follows:
[0035] 1.1) When an incoming station is detected, first judge whether the previous station has been reported, if not, go to 1.2); if yes, repeat step 1.1);
[0036] 1.2) Determine whether the location in the interval is valid, if yes, add 1 to the number of missed reports; if not, r...

The invention provides a method and a device for correcting automatic station reporting errors of an automobile. The method comprises the following steps of 1) marking stations of which the number of reporting omission times is larger than n; 2) in normal operation schedule of the automobile, in an interval between a front station and an after station of an error station, when the automobile performs a station arriving action, recording a current coordinate as a position A, and repeating the step 2) in the later normal operation schedules, thereby recording a position B and a position C; 3) respectively calculating the distance between A and B, the distance between B and C and the distance between A and C, if the distances are smaller than a preset value L, calculating a central point of a real station area which is formed by the three points as a real station position; and 4) updating the coordinate of the real station position into a line file of a station reporting system, and reporting the coordinate to a station database of an automobile management monitoring platform. The method and the device provided by the invention have advantages of finding and correcting the error of the line file in time, preventing automobile station reporting faults caused by line acquisition errors, reducing manpower and physical resource in terminal maintenance, improving maintenance efficiency and reducing maintenance cost.
Description
Technical field [0001] The invention relates to the field of vehicle automatic station reporting systems, in particular to a method and device for correcting vehicle automatic station reporting errors. Background technique [0002] The automatic bus stop reporting system on vehicles has been widely used. This system uses real-time satellite positioning technology to match the longitude and latitude of the current vehicle position with the longitude and latitude of the station in the pre-imported route file. If the matching is successful, the stop reporting process will be executed. The pre-imported route files are usually collected manually. In the suburbs or places where there is no obvious bus station, the collected stations often have errors, resulting in error stations reporting station failures. [0003] The usual steps to troubleshoot such failures are: [0004] ①The bus driver will feedback the information of the unreported station to the technician; [0005] ②The technician c...
