Intelligent vehicular terminal based on Beidou system

Abstract

The invention provides an intelligent vehicular terminal based on a Beidou system; the intelligent vehicular terminal can be better adaptive to closed places, such as tunnels and underground garages; the intelligent vehicular terminal comprises a Beidou vehicular terminal host (1), an automobile running parameter acquiring module (2), a camera (3), a power supply (4) and a chassis (5); both the automobile running parameter acquiring module (2) and the camera (3) are electrically connected with the Beidou vehicular terminal host (1); the power supply (4) is installed on an automobile and used for providing electricity for various electrical parts; the intelligent vehicular terminal is characterized by further comprising a relay signal transmitting module (6) and a relay signal receiving module (7); both the relay signal transmitting module (6) and the relay signal receiving module (7) are electrically connected with the Beidou vehicular terminal host (1); the relay signal transmitting module (6) is used for sending relay signals to other peripheral vehicles; and the relay signal receiving module (7) is used for receiving the relay signals transmitted by the peripheral vehicles.

Description

technical field [0001] The invention relates to a vehicle-mounted terminal used for monitoring the operation of a transport vehicle, in particular to an intelligent vehicle-mounted terminal based on a Beidou satellite navigation and positioning system. Background technique [0002] With the rapid development of automobile technology and satellite technology, vehicle-mounted terminals have emerged. There are many types of vehicle-mounted terminals in the existing technology. At present, most of them are vehicle-mounted terminals based on GPS positioning. The Beidou satellite positioning system developed can already provide people with relevant services, so there is the emergence of the Beidou vehicle-mounted terminal. The Beidou vehicle-mounted terminal in the prior art is the host of the Beidou satellite monitoring system, which mainly realizes positioning and navigation through the Beidou satellite; And communicate with the monitoring center through the transmission network...

AI Technical Summary

Problems solved by technology

The applicant for the patent of the present invention combined the actual driving experience of several transport vehicles and relevant accident statistics and found that the existing Beidou vehicle-mounted terminals still have the following deficiencies: figure 1 , the communication mode adopted by the Beidou vehicle-mounted terminal in the prior art is independent communication between the bicycle and the satellite. , each terminal is installed on a car, and each terminal is independent to communicate with the Beidou satellite (01) in the sky

One problem with this structure is that when the vehicle enters a closed place such as a tunnel or an underground garage, it is easy to lose connection with the satellite. The information will disappear, and the remote monitoring platform will not be able to know the specific location of the vehicle

In addition, when the positioning device on the smart vehicle terminal fails and cannot work normally, the vehicle immediately loses contact with the satellite and cannot continue to obtain positioning information

However, vehicles often need to pass through tunnels or drive into closed places such as underground garages during actual driving. If communication with satellites cannot be achieved during this process, it will cause inconvenience to positioning and remote vehicle management systems.
