The invention discloses a method for implementing
electronic toll collection, which comprises the following steps: a distance between a trigger ground sensor and a snapping ground sensor is determined; the trigger ground sensor triggers a lane reader-writer when detecting that a vehicle travels into an antenna communication area; a vehicle-mounted electronic
label caries out power detection on a received
signal sent by the lane reader-writer and returns a response
signal added with a detection result to the lane reader-writer; and the lane reader-writer sends a determined MAC (Medium
Access Control) address corresponding to the vehicle-mounted electronic
label to be stored in the stack of a background computer in order to realize collection transaction. The method disclosed by the invention ensures that the lane reader-writer can determine the corresponding relation of the vehicle-mounted electronic
label in temporal order, which not only solves the problem of vehicle following interference, but also enhances the accuracy of vehicle following collection.
