Bus arrival distance forecasting and geographical position positioning method

Abstract

The invention provides a bus arrival distance forecasting and geographical position positioning method. The method comprises the steps that: a bus driving path, a path length, and specific positions of a plurality of reference points (stations) in the path are pre-determined; with a built-in speedometer of the bus, the distance already covered by the bus is obtained; the values of the distances between the bus and the plurality of reference points in the path are calculated; the position of the bus in the driving path is calculated; the actual geographical position of the bus in a map is calculated; and the result is transmitted to any networking device of the internet through the internet, or is used for notification through voice and short messages. Therefore, the forecasting of the distance information of the bus from any station of the path is realized.

Description

Technical field [0001] The present invention relates to a method of determining the location of a vehicle moving along a known route, more specifically such as a bus. Background technique [0002] The existing bus forecasting systems are based on GPS and other satellite positioning systems. The location returned is the absolute address of latitude and longitude, which is only suitable for marking the location on the map. However, it is too complicated to predict the distance information from a station: First, it is necessary to infer the location of the vehicle in the street based on the positioning information and the positioning accuracy radius (usually 10 meters for civil GPS) and the route street where the vehicle should normally be located. , And then do the map distance integral calculation to get the position from a certain station. Summary of the invention [0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a met...
