Automatic voice stop reporting method for bus and stop reporting device thereof

Abstract

The invention discloses a bus automatic voice station reporting method which comprises the steps as follows: 1) the longitudes, the latitudes, the standard pull in / out directions, the direction angle judgement thresholds alpha and the distance judgement thresholds L of all bus stations are stored in advance; 2) the current longitude, the latitude and the actual pull in / out direction angle of the bus are obtained by a GPS positioning system; 3) the current longitude, the latitude and the actual pull in / out direction angle of the bus are compared with the longitude, the latitude and the standard pull in / out direction angle of the bus which are stored in advance; and 4) voice station reporting is carried out according to a matching result. The invention has the beneficial effects of realizing the bus automatic voice station reporting, ensuring exact station reporting and no missing or reporting by mistake and the like.

Description

technical field [0001] The invention relates to a bus voice station announcement technology, in particular to a bus automatic voice station announcement method and a station announcer. Background technique [0002] At present, in order to reduce the operating costs of public transport companies, many bus lines have adopted unmanned ticket vehicles; in the absence of conductors, in order to enable passengers to get on and off normally, most of these vehicles are equipped with voice announcement systems; Voice station announcement system is usually divided into two types: manual station announcement system and automatic station announcement system. [0003] The manual station announcement system is manually operated by the driver. When arriving or leaving the station, the driver presses the corresponding button, and the system voice prompts passengers to get on and off or prepare for action; the main disadvantage of this system is that the system completely depends on the driv...

Problems solved by technology

Since the GPS modules currently on the market are all commercial-grade protocols, their static error can reach 15 meters, and the error is even greater when there are tall buildings, tree-shaded roads or when the vehicle is moving at a high speed, so it is very easy to miss the station;

[0006] (2) The frequency of data output by the GPS module itself is once per second. When the vehicle speed reaches 60km / h, the distance traveled per second exceeds 16 meters, and the positioning error of GPS makes the phenomenon of missing stations more serious;

[0007] (3) On special road sections, the driver may approach or cross the round-trip dividing line when driving, which may easily cause misreporting;

[0008] (4) Some systems have judged the direction of uplink and downlink (running direction between two starting stations of the line) to prevent misreporting, but the algorithm of this scheme is complicated and very dependent on the judgment of the starting station. If there is a false report at the starting station , it will seriously affect the subsequent site judgment

At the same time, if individual vehicles return before arriving at the terminal due to accidents or other reasons, this solution will still cause a large number of false positives
