Vehicle positioning system based on intelligent terminal and key

Abstract

The invention discloses a vehicle positioning system based on an intelligent terminal and a key. The vehicle positioning system comprises an intelligent vehicle-mounted terminal, an intelligent vehicle key, an intelligent mobile phone and a server. The intelligent vehicle-mounted terminal comprises a microprocessor A, a Beidou / GPS double positioning module connected with the microprocessor A, an acceleration sensor connected with the microprocessor A, a gyroscope connected with the microprocessor A, a bluetooth module A and a network communication module connected with the microprocessor A anda power supply module. According to the vehicle positioning system, the vehicle positioning accuracy can be enhanced, the current position information of the vehicle can be obtained according to theprinciple of inertial navigation under the condition of satellite signal blocking, and the technical problem of failure when the vehicle positioning device cannot acquire the satellite signal can be avoided. Meanwhile, the historical and current position information of the vehicle can be inquired through the intelligent mobile phone so as to perform remote monitoring of the driving state of the vehicle.

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...

Problems solved by technology

[0006] In view of this, the purpose of the present invention is to provide a vehicle positioning system based on an intelligent terminal and a key to solve: the existing vehicle locator uses a single satellite positioning system, and the positioning accuracy is limited; The satellite signal cannot be obtained in the middle of the car, which leads to the failure of the tracker; the vehicle status cannot be queried and monitored through the smart phone, and the smart car key cannot be used to remotely wake up the vehicle positioning system and other technical problems.
