Problems solved by technology

Most of the existing vehicle-mounted terminals are based on the GPS navigation and positioning system, and the external communication must pass through the mobile communication network, which makes it impossible for the vehicle-mounted terminal to communicate with the outside world when the network signal is not good, and the received positioning information cannot be reported to the background server, and the background server cannot Know the location of the vehicle, which makes the safety of the vehicle unsafe
Especially in the fields of special tourism and unmanned land development, there is no mobile communication network signal, and the corresponding vehicle terminal cannot communicate with the outside world, which will cause huge security risks
At the same time, most of the existing vehicle-mounted terminals do not have the positioning enhancement function, and the positioning accuracy is low, generally around 5-10m. The overall functional design is not complete, and the performance and reliability design also needs to be improved urgently.

Abstract

The invention discloses a Beidou and GPS dual-mode vehicle-mounted terminal system. Through control of an embedded microprocessor, functions of Beidou RDSS (Radio Determination Satellite Service) positioning, Beidou RDSS short message communication, Beidou / GPS RNSS (Radio Navigation Satellite System) positioning, short message and TCP / IP (Transmission Control Protocol / Internet Protocol) communication, Bluetooth communication and pseudorange differential positioning accuracy enhancement can be realized. The vehicle-mounted terminal designed and implemented in the invention has complete functions and features of sub-meter high precision, low power consumption and high reliability. The Beidou / GPS vehicle-mounted terminal is successfully used in special tourism, development of no-human zones and other fields.

Description

technical field [0001] The invention relates to a Beidou and GPS dual-mode vehicle-mounted terminal system, and relates to the technical field of Beidou / GPS positioning and navigation applications. Background technique [0002] Vehicle-mounted terminals based on Beidou and GPS positioning and navigation technologies need to improve positioning accuracy and communication capabilities, reduce power consumption, optimize performance and ensure reliability. Most of the existing vehicle-mounted terminals are based on the GPS navigation and positioning system, and the external communication must pass through the mobile communication network, which makes it impossible for the vehicle-mounted terminal to communicate with the outside world when the network signal is not good, and the received positioning information cannot be reported to the background server, and the background server cannot Knowing the location of the vehicle makes the safety of the vehicle impossible to guarantee....
