Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] With reference to accompanying drawing, a kind of bus terminal automatic station reporting method, described automatic station reporting method comprises the following steps:

[0034] (1) Read the bus line data information file to obtain the line coordinate data of the line, mainly including the stop sign coordinates of each station and the line feature point coordinates between the stop sign coordinates. According to the input line coordinate data, the coordinates of the station sign points in the line coordinate data are used as the reference coordinates of the inbound station announcement, and the station shift algorithm is used to calculate the reference coordinates of the outbound station announcement, and the reference coordinates of the inbound station announcement and the outbound station announcement reference coordinates are used. The coordinates are a...

Abstract

An automatic station announcement method of a public transportation vehicle-mounted terminal comprises the steps as follows: 1), according to input line coordinate data, get-in station announcement reference coordinates and departure station announcement reference coordinates are alternated, so that get-in and departure station announcement reference coordinate sequences are formed; and the sequences are saved according to up directions and down directions of lines. 2), according to task information, an up direction or down direction station announcement reference coordinate sequence of a corresponding line is selected, and a station announcement reference coordinate index is initialized. 3), current initial coordinate data of a vehicle are acquired from GPS (global position system) equipment, the data are processed with a coordinate correcting algorithm, a corrected coordinate is obtained, and the corrected coordinate is taken as a station announcement judgment coordinate. 4), an Euclidean distance d between the station announcement judgment coordinate of the vehicle and a current announcement reference coordinate is calculated. 5), after get-in station announcement of the vehicle is realized, if the vehicle stays for a certain period of time T sec outside a secondary station announcement area, get-in secondary station announcement is triggered after the vehicle enters the secondary station announcement area R sec.

Description

technical field [0001] The invention relates to a method for automatic station reporting by a vehicle-mounted terminal of a bus. Background technique [0002] The automatic station announcement of public transport vehicles is a very important function in the intelligent public transport system. The automatic station announcement of the bus can not only avoid the driver's operation error, greatly reduce the phenomenon of missed station, wrong station and late station announcement, but also reduce the driving intensity of the driver and prevent the occurrence of traffic accidents. important practical application value. [0003] At present, civilian GPS technology has been popularized, and the automatic station announcement of bus terminal is mainly based on GPS technology. The basic working process of the vehicle-mounted terminal's automatic station announcement is as follows: the vehicle-mounted terminal obtains the GPS coordinates of the vehicle by using GPS technology, ma...
