Abstract
The invention discloses an intelligent early warning method for a surrounding vehicle with an abnormal driving state. Vehicle driving state parameters are read via a roadside relay end or a vehicle-mounted reading end, the data are simultaneously submitted to a backstage system or a vehicle-mounted processing system, the backstage system or the vehicle-mounted processing system tracks or marks a vehicle driving electronic trajectory, vehicle instant state parameters comprise a driving speed, a driving direction and an inter-road position instant state, whether the vehicle driving state is abnormal is judged, or after the abnormal type is further confirmed, vehicle abnormal state warning information is sent to the vehicle. As the widely-used RFID technology is adopted, the cost is lower, the application is more convenient, and the method can be forced to be promoted by the government in a unified mode; according to the technology system for intelligent warning, judging and recognizing the abnormal driving vehicle, the surrounding other driving vehicles are warned instantly, effective and reasonable avoidance measures are adopted, and traffic safety accidents can be prevented from happening; and a special global meaning is provided for ensuring safe vehicle driving.
Description
Technical field
The invention belongs to the intelligent management technical field of vehicle safe driving, mainly relate to a kind of based on RFID less radio-frequency and data relay transmission technology thereof, realize the intelligent early-warning method to the abnormal transport condition vehicle of periphery.
Background technology
Radio-frequency (RF) identification (RFID) is a kind of wireless communication technology, can read and write related data by radio signals identification specific objective, and without the need to setting up machinery or optical contact between recognition system and specific objective.The most important advantage of radio-frequency recognition system is contactless identification, and it can penetrate the rugged surroundings label reading that snow, mist, ice, coating, dust and dirt and bar code cannot use, and reading rate is exceedingly fast, in most cases less than 100 milliseconds.The literary sketch ability of active radio-frequency recognition system is also important advantage.Can be used for the interactive service such as flow tracking and maintenance tracking.
The safe driving of automobile, it is a topic of general concern today, due to socioeconomic development, sharply increasing of automobile quantity, the road traffic accident caused also is more and more, and traffic safety is not only a livelihood issues, especially a social concern and political issue, how effectively transport solution safety problem, this is the thing that supvr and scientific worker must pay attention to.
How intelligent early-warning judges to identify the abnormal vehicle travelled, and immediately gives nearby vehicle warning, and takes effective and reasonable measures to keep clear, existing also not relevant traffic safety technology and practical application, also do not have similar patent open through retrieval.
