Abstract

The invention discloses an intelligent vehicle terminal based on Beidou and global positioning system (GPS) dual modes. The intelligent vehicle terminal comprises a microprocessor, a Beidou / GPS dual-positioning module connected with the microprocessor, an acceleration sensor connected with the microprocessor, a gyroscope connected with the microprocessor, a network communication module connected with the microprocessor, and a power module. The intelligent vehicle terminal not only utilizes the joint positioning of a Beidou navigation system and a GPS positioning system to determine the location of a vehicle, but also fuses satellite positioning signals, the detection information of the gyroscope and the acceleration sensor as well as the vehicle position information of the previous momentby means of the microprocessor, thus further reducing the positioning error of a satellite positioning system, and improving the positioning accuracy of the vehicle. Furthermore, the intelligent vehicle terminal can obtain the current position information of the vehicle according to the inertial navigation principle and can avoid the technical problem that a vehicle locator fails when satellite signals cannot be obtained in the case that the Beidou / GPS dual-positioning module in a deep mountain, a tunnel and the like is blocked when acquiring the satellite signals.

Description

technical field [0001] The invention relates to the technical field of Internet of Things positioning related to a smart positioning system, in particular to a vehicle-mounted locator. Background technique [0002] The Global Positioning System (English: Global Positioning System, usually referred to as GPS), also known as the Global Positioning System, is a medium-distance circular orbit satellite navigation system. It can provide accurate positioning, speed measurement and high-precision time standards for most areas on the earth's surface. Developed and maintained by the U.S. Department of Defense, the system can meet the continuous and accurate determination of three-dimensional position, three-dimensional motion and time of military users located anywhere in the world or in near-earth space. [0003] The Beidou positioning system is a global satellite navigation and positioning system independently developed and implemented in my country, abbreviated as BDS. Also known...
