Electronic toll collection communication method, device and system

Abstract

The invention belongs to the field of intelligent traffic and relates to an electronic toll collection communication method, device and system. The method comprises the following steps of: obtaining resetting information of an intelligent card by a vehicle-mounted unit; judging whether a mark of the existing intelligent card contained in the resetting information is the same as the previously-reserved intelligent card mark or not by the vehicle-mounted unit; when the mark of the existing intelligent card is different from the previously-reserved intelligent card mark, replacing the previously-reserved intelligent card mark by the mark of the existing intelligent card through the vehicle-mounted unit and feeding responding information with card exchange information back to road side equipment; and carrying out corresponding process by the road side equipment according to the received responding information with the card exchange information. With the adoption of the method disclosed by the invention, the problem that some users viciously exchange the card to expend fewer tolls in an electronic toll collection system is solved, thereby preventing the loss of an expressway owner.
