Vehicle-mounted terminal of intelligent transportation system based on Internet of things and dynamic three-dimensional geographic information system (3D GIS)

Abstract

The invention discloses a vehicle-mounted terminal of an intelligent transportation system based on the Internet of things and a dynamic three-dimensional geographic information system (3D GIS). The vehicle-mounted terminal comprises a wireless communication module, an information storage module, a road condition collecting instrument, a port matched with a vehicle body automatic control system, an electromagnetic buffer device, a 3D GIS module and a control unit, wherein the wireless communication module, the information storage module, the road condition collecting instrument, the port, the electromagnetic buffer device and the 3D GIS module are connected with the control unit. The control unit is used for processing and analyzing instructions sent by a server, real-time three-dimensional information, road condition information sent by a road monitoring device and three-dimensional information sent by the vehicle-mounted terminal of each transportation participation body, and sending instructions to the port matched with the vehicle body automatic control system and the electromagnetic buffer device. According to the vehicle-mounted terminal, comprehensive road condition information is learned about conveniently, effective management of transportation is achieved, stable driving of the vehicle-mounted terminal is guaranteed, crash and rear-end collision accidents between vehicles are avoided, and geographic data are formed conveniently.

Description

technical field [0001] The invention belongs to the technical field of traffic control, in particular to a vehicle-mounted terminal of an intelligent traffic system based on the Internet of Things and dynamic 3D GIS. Background technique [0002] The development of information technology has made the Internet of Things technology more and more widely used. The Internet of Things uses information sensing equipment such as radio frequency identification, infrared sensing, positioning systems, and laser scanning to connect items or equipment to the Internet according to agreed agreements. Connected for information communication to realize intelligent identification, tracking, positioning, monitoring and management of the network system. Three-dimensional geographic information system is a specific spatial information system, which collects, stores, manages, calculates, analyzes, displays and describes the relevant geographical distribution data in the whole or part of the space...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the vehicle-mounted terminals of traditional intelligent transportation systems use GPS, and GPS can basically only realize functions such as tracking and navigation, and cannot provide three-dimensional road condition information, which will make it difficult to achieve effective traffic management; at the same time, the vehicle-mounted The terminal is not equipped with an interface that matches the automatic control system, and remote automatic control of the vehicle terminal cannot be realized
