GPS-based vehicle positioning control system

Abstract

The invention discloses a GPS-based vehicle positioning control system, which includes a vehicle terminal and a single-chip microcomputer controller. The front end face of the vehicle terminal is provided with a camera and a sound sensor in order from left to right. The single-chip microcomputer controller is electrically connected to a data memory, a data processor, and a radio frequency transceiver, separately. An input end of the single-chip microcomputer controller is electrically connected with output ends of a GPS satellite data acquisition processor, an image acquisition processor, an audio acquisition processor and a power supply controller. An output end of the single-chip microcomputer controller is electrically connected with input ends of a vehicle circuit controller, a vehicle oil passage controller and a filter. The radio frequency transceiver is connected to an external device through a GPRS network. An input end of the power supply controller is electrically connected with output ends of an external power supply and an internal power supply, separately. The system of the invention has a high degree of intelligence and has the functions of remotely positioning, controlling and monitoring a vehicle.

Description

technical field [0001] The invention belongs to the technical field of vehicle positioning equipment, in particular to a GPS-based vehicle positioning control system. Background technique [0002] With the rapid development of modern society, people put forward higher and higher requirements for positioning technology. The global positioning system has been paid more and more attention by people. GPS can provide vehicle positioning, anti-theft, anti-robbery, driving route monitoring and call command. and other functions. [0003] The basic principle of the GPS navigation system is to measure the distance between the known satellite and the user's receiver, and then integrate the data of multiple satellites to know the specific position of the receiver. Specifically, the position of the satellite can be found in the satellite ephemeris according to the time recorded by the on-board clock. [0004] To sum up, the problems existing in the prior art are: the GPS positioning sy...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the problems existing in the prior art are: the GPS positioning system mainly provides positioning and anti-theft functions for the vehicle in the vehicle, and the function is relatively single, and the GPS positioning system is extremely susceptible to electromagnetic interference because of the electronic components. When the power supply circuit of the system is damaged, the positioning function cannot be realized in a timely and effective manner; moreover, the existing GPS positioning system has low intelligence and poor security and stability
