Abstract

The invention discloses an intelligent traffic vehicle communication system with a data first-in first-out function, which relates to an intelligent traffic system and aims at solving the technical problems that the existing anti-collision system has a small information acquisition range, data transmission between centre control processors is poor in continuity, and the cloud intelligent traffic service and the wireless technology are poor in practical experience and have hidden safety dangers and the like. The system, in the structure, comprises a remote information communication unit and a visible light short range signal transceiver, wherein the remote information communication unit comprises a network access device and a remote information control unit, the network access device comprises a digital signal processing unit, and the remote information control unit comprises a field programmable logic gate module connected with the digital signal processing unit. The system of the invention is used for vehicle collision prevention.

Description

technical field [0001] The invention relates to an intelligent transportation system, in particular to an intelligent transportation vehicle communication system with a data first-in first-out function. Background technique [0002] The existing vehicle-mounted anti-collision system integrates a large number of sensors to collect the running status of vehicles on the road and analyze whether there is a possibility of collision; although high-sensitivity sensors can obtain accurate data, their collection distance is very limited. , it is impossible to give an early warning, or even with an early warning, the driver does not have enough time to fully avoid it, thus causing possible traffic accidents. Further, in the high-end car series, cloud-based intelligent traffic services are used to provide certain road warnings. However, considering the actual use, due to the complexity of the roads, the existence of technical problems such as network popularity and connection stability...
