A system and method for onboard terminal based on traffic information grid platform

Abstract

A vehicle borne terminal system and method based on traffic information network platform comprises the traffic information network as the back stage to provide timely traffic information, vehicle borne computer from Shenzhou Longxin network computer and touch display, with the processor of No.1 of the LongXin using MIPS instruction collection, linking with the parallel input and output together with the display, connecting the signal collection device and radio modulator through two RS232 serial port and GPS, the vehicle borne terminal communicating with the back traffic information grid timely through the radio communication network to realize all kinds of front and back services. It not only completes all kinds of front services, but also displays the overall timely status of the road based on the dynamic navigating service and moving yellow page.

Description

technical field [0001] The invention relates to a vehicle terminal system and method based on a traffic information grid platform. Background technique [0002] In recent years, with the rapid development of microelectronics technology and the rapid decline of GPS chip manufacturing costs, car navigation products based on GPS navigation and map data matching technology have begun to enter the market and have grown rapidly. Due to the huge market potential and immeasurable development prospects, almost all automobile manufacturers in the world have participated in this high-tech competition, and more than 30 new systems have been put into the market in recent years. Companies such as Hongda, Nissan, Honda, Mazda, Mitsubishi, Panasonic, Pioneer, Alpine, and Kenwood in Japan have all developed their own car navigation products; The market has its place. [0003] The current on-board navigation systems of this type are all autonomous navigation. The so-called autonomous naviga...
