Intelligent expressway toll and prewarning system and method thereof

Abstract

This invention relates to an intelligent charge and an early warning system and a method for thruways composed of a super RF card, a read-write device, electronic road signs and on-line servers, in which, cars with the super RF cards can exchange information with the read-write device to pass through non-stopping charge ports, when cars without the cards enter the road and fetch the cards, watch persons will write the car information into the super RF card A by the computer or a read-write device, when cars with the RF cards pass through the electronic road signs, they will receive information from the road signs and A records the route information of the car and reverts it to the electronic road sign C , which sends the information collected by a public net to the on-line server wirelessly, so that the road management department realizes scientific dispatch and the super RF card receives the warning information of the electronic cursor or RF card of the cars ahead to warn for prompt to realize scientific charge and safety early warning of roads.

Description

technical field [0001] The invention relates to an intelligent expressway toll collection and early warning system and a method thereof, belonging to the field of electronic information, and is an upgrade and replacement product of the existing expressway toll collection system and expressway safety early warning system. Background technique [0002] By the end of 2005, China's expressway mileage had reached 40,000 kilometers, ranking second in the world, and the global expressway mileage had exceeded 240,000 kilometers. Guangdong Province launched a networked toll collection system at the end of 2004, using "electronic tags, vehicle-mounted units, and dual-interface IC radio frequency cards" to realize the province-wide networked single-lane non-stop toll collection, but it currently only meets the charging function and cannot determine the vehicle The actual walking path; in addition, to adopt this charging method, a special toll lane must be built, and the cost of this sp...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the reasonable toll collection of expressways and take into account the functions of automatic and semi-automatic toll collection, the patent invention application with application number 200410016817.4 has announced a "vehicle unit for expressway toll collection system" that utilizes IC card toll collection, but this invention has the following defects : (1), the vehicle-mounted unit installed on the car is troublesome to install, the cost is high, and it is inconvenient to popularize; (2), the vehicle-mounted unit cannot be organically combined with the payment IC card into a portable individual; (3), the road section passed by cannot be recorded Coordinate information cannot be used for early warning

This kind of radio frequency card has the following defects: (1) the reading and writing data communication distance is short; (2) the data transmission flow is small, and the reading and writing cycle is long; (3) it cannot be used in a fast-moving environment; (4) the information data storage capacity Small; (5) Poor anti-collision capability; (6) Single function, not easy to expand usage

[0005] Again, the patent application No. 02153172.2 discloses an intelligent expressway early warning system, but the system has the defects of large size, incompatibility with the toll system, long-distance wireless network occupation of dedicated channels, and high cost
