Vehicle identification and positioning method

Abstract

The invention discloses a vehicle identification and positioning method, which comprises the steps that 1) unique identification chips are installed on vehicles; 2) corresponding reading-writing devices are installed on roads; positioning systems are installed in the reading-writing devices and can identify and mark the geographical positions of the reading-writing devices; and cameras can be built in the reading-writing devices and are used for obtaining image information of license plates, body colors and appearances of the vehicles with information being read, wherein the image information of license plates, body colors and appearances of the vehicles can also be obtained by using the cameras which are installed on the roads; and 3) when the vehicles pass through the reading-writing devices, the reading-writing devices superimpose the geographical position information on the vehicle identification information, then the information is transmitted to background management software, and data identified by the front-end reading-writing devices is compared with existing data by using the existing vehicle information database to identify the accurate identity information and the current positions of the vehicles.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation vehicle management, and in particular relates to a method for fast and unique identification and positioning of vehicles, which can be applied to information-based traffic safety management of vehicles and identification and positioning of vehicles used for crimes. Background technique [0002] With the continuous progress of the social economy, the number of automobiles is also increasing year by year. How to efficiently and safely manage the vehicles has become a problem that is widely concerned by the society. The current vehicle management method is mainly based on passive inspection. Fixed or mobile inspection checkpoints are set up in some places to inspect vehicles. It is inconvenient, and there may be missing checks, and it is impossible to accurately locate the management behavior. The present invention not only has conventional measures such as checking and confirmi...

Problems solved by technology

[0005] The main feature of the above technical solution is that the on-site inspection is compared with the vehicle location information transmitted to the management server by wireless means from the active equipment placed on the vehicle Vehicle information is used to identify identity information, so as to carry out other related applications; it is necessary to install a vehicle-mounted device on the vehicle, and use the device to locate the vehicle; the vehicle-mounted equipment is required to include positioning units, communication units and peripheral control drive units, which are active Equipment; the vehicle-mounted device used to realize identity recognition and positioning includes a positioning unit, a communication unit, and a peripheral control drive unit; the device contains a lot of equipment, and the required power supply must be provided, and it is difficult to implement the installation of vehicle-mounted positioning equipment on all vehicles; It is necessary to compare relevant information at the inspection site to confirm whether the identity of the vehicle is legal, and passive inspection is required. If no inspection is performed, illegal vehicles will not be found; the possibility of full coverage of existing vehicles is relatively small, and the cost is also high. , and easy to remove

[0006] The above-mentioned characteristics make the method and application of identifying the identity of the vehicle disclosed in the patent document CN101692314A have such defects: the vehicle is loaded with active equipment, which increases the The line load of the vehicle has potential safety hazards, and the driver is exposed to the wireless transmitter for a long time, which is harmful to the human body, and the owner is more resistant
