A device and method for navigation and positioning using Beidou

Abstract

The invention discloses a device and method for positioning and navigation using Beidou. The built-in functional modules of the device include a main control module, a positioning and navigation module, a voice recognition and information storage module, a communication and power supply module, a voice navigation module and a signal processing module. After receiving the user's voice navigation demand command, the positioning and navigation module receives the user's positioning coordinates and transmits the position information to the main control module, and the signal processing module receives the positioning coordinates transmitted from the main control module and constructs navigation routes based on the map data of the data layer, communication and power supply After the module transmits the navigation route to the main control module, it transmits the navigation route to the user through the voice navigation module. The device has high positioning accuracy, small size, and is easy to carry. The navigation algorithm can calculate the user's geographic location and attitude information such as roll, pitch, and yaw. By dynamically adjusting and updating the user's geographic location and motion acceleration and other parameters, it can improve Accuracy and reliability of positioning system navigation device and method.

Description

technical field [0001] The invention relates to the technical field of positioning and navigation, in particular to a device and method for using Beidou navigation and positioning. Background technique [0002] With the continuous development of my country's society and economy, the continuous improvement of people's living standards, and the rapid development of the transportation industry, the number of private cars, business vehicles and other motor vehicles in my country has maintained a continuous and rapid growth trend. According to statistics, by the end of 2016, the number of motor vehicles in China was 327 million, an increase of 12 million over the previous year. The increase in the number of motor vehicles has brought about more and more various social problems. Vehicle drivers' violations of the Road Traffic Safety Law can be seen everywhere, such as speeding, random lane changes, long-term occupation of overtaking lanes, emergency lanes, Arbitrary parking etc. ...

AI Technical Summary

Problems solved by technology

At present, the vehicle monitoring and navigation products on the market generally use GPS from the United States. The accuracy of pure GPS positioning for civil use is generally at the ten-meter level, which is difficult to meet some high-precision location applications, and lacks high-precision electronic map data support. , which severely restricts the improvement of the traffic management department's ability to supervise vehicles, and is even more unable to meet the growing demand of the traffic management department for refined vehicle management
