Vehicle metering system based on blue-teeth communication and intelligent identification technology

Abstract

The present invention utilizes Bluetooth communication adaptive frequency hopping technique to implement short-distance two-way wireless information transmission, so that it can effectively raise anti0interference capability of charging system, under the condition of non-stopping drive the car can implement accurate payment of toll. Said invention adopts an intelligent mode identification method to implement quick and accurate identification of license so as to raise charging efficiency. Said invention can be extensively used in various toll points (gates).

Description

technical field [0001] The invention relates to a vehicle charging system, in particular to a vehicle charging system based on bluetooth communication and intelligent identification technology. Background technique [0002] With the development of transportation and the increasing scale of traffic road construction, the management of traffic construction facilities is becoming more and more important, and the most prominent thing in management is the implementation of station tolls for traffic construction facilities such as roads, bridges, and tunnels. The problem is that currently all highways, bridges, tunnels and other traffic construction facilities are generally charged by one-way manual operation. Vehicles must stop and pay, and you must know what kind of car it is and what standard it is charged for. Once you drive People do not have change, and they have to make a lot of change. It takes a long time to pass the station, causing traffic jams during peak traffic hours...

[0002] With the development of transportation and the increasing scale of traffic road construction, the management of traffic construction facilities is becoming more and more important, and the most prominent thing in management is the implementation of station tolls for traffic construction facilities such as roads, bridges, and tunnels. The problem is that currently all highways, bridges, tunnels and other traffic construction facilities are generally charged by one-way manual operation. Vehicles must stop and pay, and you must know what kind of car it is and what standard it is charged for. Once you drive People don’t have change, and they have to make a lot of change. It takes a long time to pass the station, causing traffic jams during peak traffic hours, and there may be loopholes in cash management. In addition, vehicles passing illegally cannot be identified in real time.

In order to solve the above problems, people have tried a variety of automatic toll collection systems, but due to the lack of short-distance wireless technology support, they have not played a real role; smart IC cards have also been used for vehicle transit billing charges, etc., but using When using a smart IC card, the vehicle also needs to stop and approach or touch the toll booth to bill and charge, and the smart IC card cannot accurately identify the vehicle identity. At the same time, in order to identify the vehicle identity, ensure the accuracy of each charge , the one-to-one algorithm and the one-to-many algorithm are mainly used in the recognition technology. The former requires too many discriminant functions, and the accuracy of the latter is difficult to guarantee.
