Problems solved by technology

However, the latitude and longitude coordinates received by the positioning satellite 16 often have a certain error range, and the range of error often makes it impossible for the receiving equipment to accurately estimate the arrival time of the bus under normal circumstances; in addition, in the wireless communication module 26 and the wireless communication module 32 in the data transmission aspect also will have the factor of data transmission failure and delay; In addition, the route of the bus system in the urban area will have the factors of short station distance and multiple stations interlaced, thus often causing failure Correctly estimate the arrival time of the bus, which greatly reduces the accuracy of predicting the arrival of the bus

Embodiment Construction

[0023] Please refer to FIG. 2 , FIG. 3 , and FIG. 4 . FIG. 2 , FIG. 3 , and FIG. 4 are flow charts of the present invention for estimating the travel path of vehicles using the global satellite positioning system. The method of the present invention can be applied to a bus monitoring and management system, so the vehicle can be a bus. Method of the present invention comprises the following steps:

[0024] Step 100: Use the global satellite positioning system to receive the first coordinate position of the vehicle at the first time.

[0025] Step 102: Using the global satellite positioning system to receive a second coordinate position of the vehicle at a second time later than the first time.

[0026] Step 104: Find the positions of a plurality of neighboring relay points near the vehicle by using the global positioning system.

[0027] Step 106: Generate a vector according to the first coordinate position and the second coordinate position.

[0028] Step 108: Generate a pl...

Abstract

A method of utilizing GPS to predict driving path of transportation means includes receiving the first coordinate position of transportation means by GPS at the first time, receiving the second coordinate position of transportation means by GPS at the second time later than the first one, finding out positions of multiple adjacent relay points near to transportation means by GPS and judging out driving path of said transportation means according to the first and the second coordinate positions as well as positions of multiple adjacent relay points.

Description

technical field [0001] The present invention provides a method for estimating the driving path of vehicles by using the global satellite positioning system, especially a method for estimating the driving path of the vehicles according to the vector formed by the coordinate positions received by the global satellite positioning system. Background technique [0002] In the past, the establishment of the global positioning system (GPS) was mainly for military purposes, such as the positioning of ships in the ocean, or the navigation and positioning of missiles, etc., and with the development of the global positioning system, It has been widely used in the lives of the general public. The global satellite positioning system mainly includes multiple positioning satellites, a ground control center (controlcenter), and a client. The positioning satellites are distributed on the earth orbit and are used to transmit positioning signals containing distance data. Generally speaking, a ...
