Embodiment

[0015] A vehicle access card system applied to expressways, comprising a vehicle access card part and a controller part.

[0016] The controller part includes a control center and a power supply module. The control center is used to compare the three-dimensional position coordinates of the vehicle with the internally stored road network identification point coordinates, and compare the road network identification points whose distance from the vehicle three-dimensional position coordinates is less than the allowable error value. Storage; the control center is connected with a radio frequency signal communication device and a wireless signal communication device; the radio frequency signal communication device is used for communicating radio frequency signals and inducting radio frequency communication modules; the wireless signal communication device communicates wireless signals and is used for wireless communication.

Abstract

The invention discloses a vehicle password card system applied to an expressway. The vehicle password card system is characterized by comprising a vehicle password card portion and a controller portion. The controller portion comprises a control center and a power module. The control center is connected with a radio frequency signal communication device and a wireless signal communication device. The vehicle password card portion comprises a card body. A GPS signal receiving processing module and a non-contact radio frequency communication module are arranged on the card body. According to the vehicle password card system, license plate numbers can be recorded in a picture or data mode. Due to the GPS signal receiving processing module and a satellite positioning system, a wheelpath can be recorded, whether behaviors such as overtaking and illegal parking exist or not is judged, the wheelpath is automatically input to a computer storage system when a vehicle leaves an expressway intersection, and evidences can be conveniently obtained by the police or the expressway administrative department.

Description

technical field [0001] The invention belongs to the field of expressway vehicle access systems, and in particular relates to a vehicle access card system applied to expressways. Background technique [0002] At present, expressways in most provinces in my country have implemented network toll collection, and network toll collection adopts a closed toll system. The closed toll system collects tolls according to the vehicle type and mileage, and then dismantles the collected fees and delivers them to the vehicles. The operator of the passing road segment. Since vehicles can have a variety of routes to choose when driving in the road network, the driving route of all vehicles must be uniquely determined, otherwise the mileage and road section of the vehicle cannot be determined, and the toll cannot be determined. cannot proceed. Therefore, the problem of vehicle route identification in the expressway network is a key problem that must be solved for network toll collection. ...
