Movement trail recording and redrawing system based on BeiDou navigation satellite system

Abstract

The invention relates to the field of spatial orientation, in particular to a movement trail recording and redrawing system based on the BeiDou navigation satellite system. According to the movement trail recording and redrawing system based on the BeiDou navigation satellite system, a BeiDou navigation satellite module, a single-chip microcomputer control module, a data storage module and an USB interface are connected in sequence, and a mode selection key and a display module are connected with the single-chip microcomputer control module; positioning information including UTC time, the longitude, the latitude, the number of satellites, the speed, the height and the like can be displayed according to needs of an exerciser, after movement is ended, the positioning information is loaded into a computer through the USB interface, and a movement trail is redrawn on a map according to a Gaussian projection formula transformation coordinate system combined with map data; the movement speeds on different road sections at different times can be displayed, and therefore the exerciser is helped to make an exercise plan according to the actual condition of the exerciser. In addition, the movement trail recording and redrawing system based on the BeiDou navigation satellite system can also be applied to research, development and testing of transportation tools such as an automobile, a ship and an airplane and can assist in equipment calibration and machine debugging.

Description

[0001] technical field [0002] The invention relates to the field of space positioning, in particular to an application field based on the Beidou satellite navigation system. Background technique [0003] With the improvement of living standards and the advancement of scientific research and technology, people's pursuit of health is becoming more and more intense, and the management of sports is becoming more and more important, especially for outdoor sports, such as outdoor long-distance running, bicycle competitions and cross-country competitions. People love and participate widely. At this time, it is particularly important to redraw the movement track and test and analyze the speed and movement state of different stages. Using the positioning information of the satellite navigation system, record the path, speed, time and Longitude and latitude and other parameters, and convert these parameters into motion trajectory output, scientifically and objectively grasp the stat...

Problems solved by technology

[0005] The existing platforms for spatial positioning research in the market are mostly based on the US Global Positioning System, the Russian GLONASS system and the EU Galileo positioning system. They lack the use of my country's independent intellectual property rights in terms of key technologies, and can only guarantee one-way data Transmission is not conducive to long-term scientific research deve
