Bus GPS (global positioning system) and positioning method thereof

Abstract

The invention provides a bus GPS (global positioning system) and a positioning method thereof. The bus GPS is characterized in that a bus is provided with bus GPS equipment, a bus line database is arranged locally and is in communicated connection with a bus GPS correcting calculator which is arranged locally or an application terminal, and the bus GPS equipment is connected to the bus GPS correcting calculator in a communication manner. A correcting GPS database is arranged locally, the bus GPS correcting calculator is connected to the correcting GPS database in a communication manner, and a network or local map database and the local correcting GPS database are parallel to be in communicated connection with an application terminal display module. The bus GPS and the positioning method thereof are capable of correcting bus GPS position data and describing bus positions accurately so as to provide optimal usage feeling for a user.

Description

technical field [0001] The invention relates to a bus GPS positioning system and a method thereof, belonging to the bus positioning technology. Background technique [0002] GPS positioning systems are widely used in various transportation equipment, and buses are only one example. Install GPS equipment on the bus, obtain its own GPS location information in real time, and send it to the background data center to complete the acquisition process of GPS positioning data. However, the GPS data is not accurate enough. The deviation of civilian GPS data is generally 100 meters, at least 10 meters or more. For a specific application that can display the location of the bus on Baidu Map / AutoNavi map in real time, it is necessary to use GPS Correct the position to prevent users from having the illusion that the bus is not running on the bus line correctly. [0003] Specifically, as figure 1 As shown, in the prior art, the terminal display module is used to directly read and dis...

Problems solved by technology

However, the GPS data is not accurate enough. The deviation of civilian GPS data is generally 100 meters, at least up to 10 meters. For a specific application that can display the location of the bus on Baidu map / Gaode map in real time, it is necessary to use GPS The position is corrected to prevent the user from having the illusion that the bus is not running on the bus line correctly

[0003] Specifically, as figure 1 As shown, in the prior art, the application terminal display module directly reads and displays information from the map database, the bus route database, and the bus GPS device. However, the bus route is not always a simple line segment. In practice, the bus route may have various There may even be four stations on opposite sides of a building, and the bus may deviate from the scheduled bus route due to reasons such as refueling and traffic jams during the actual driving process, which makes the application terminal display The deviation between the actual situation displayed by the module and the ideal situation is very large, and such a deviation will undoubtedly make the user feel very confused, and then produce the feeling that it is better not to perform GPS positioning, that is, the disadvantages of the existing technology are:

[0004] 1. Since the bus line is formed by the pre-stored data connection, the position of the bus on the map cannot be displayed on the bus line;

[0005] 2. Due to the error of the GPS data itself, the position of the bus on the map may not be on the road;

[0006] 3. Unable to judge the direction of the bus, so that the correct bus line that should be displayed cannot be selected, causing users to feel bad, and mistakenly believe that the application software cannot correctly display the bus location;
