Embodiment Construction
[0032] The present invention will be further described below through specific embodiments.
[0033] A method for correcting errors in automatic vehicle station reporting, which is used for identifying error stations, determining the real station positions, and then automatically correcting route files. Number all the stations in the line file of the station announcement system in advance, set n to 3 and L to 30 meters in advance, and the rest of the steps are as follows:
[0034] 1) When the vehicle is in normal operation, collect the operating status of the station reporting system in real time, and mark the stations with more than n missed reports as error stations, refer to figure 1 ,details as follows:
[0035] 1.1) When an incoming station is detected, first judge whether the previous station has reported, if not, enter 1.1); if so, repeat step 1.1);
[0036] 1.2) Determine whether the positioning in the interval is valid, if so, add 1 to the number of missed reports; i...

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 automatic vehicle station announcement system, in particular to a method and device for correcting error of automatic vehicle station announcement. Background technique [0002] The vehicle-mounted bus automatic station announcement system has been widely used. This system uses real-time satellite positioning technology to match the latitude and longitude of the current vehicle position with the latitude and longitude of the station in the pre-imported route file. If the match is successful, the station announcement process will be executed. The pre-imported route files are usually collected manually. In the suburbs or places where there are no obvious bus stops, there are often errors in the collected stations, which leads to station reporting failures at stations with errors. [0003] The usual steps to troubleshoot this type of failure are: [0004] ①The bus driver feeds back the unreported station information ...
