Embodiment Construction

[0034] The main technical idea of ​​the present invention is that, in the antenna communication area, when there are multiple vehicles at the same time, when the vehicle-mounted electronic tags installed on the front and rear vehicles are used to communicate with the lane reader, the signal attenuation is different due to the difference in the transmission path. Position the trigger ground sense and capture ground sense, determine the signal attenuation, determine the corresponding relationship between the lane reader and the vehicle electronic tag, and then conduct normal toll transactions, solve the problem of car-following interference and improve the accuracy of car-following billing Rate.

[0035] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0036] The ECT system of the present invention mainly includes, the on-board electronic tag arranged on the vehicle, the lane reader and the antenna arranged...

Abstract

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.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the field of radio frequency identification, and in particular to a method for realizing electronic non-stop charging. Background technique [0002] Among the many practical applications of Radio Frequency Identification (RFID), smart transportation is the most widely used, such as Electronic Toll Collection System (ETC), that is, non-stop toll collection system. ETC non-stop toll collection technology appeared in the early 1990s and has been widely used in North America, Europe, Japan, Australia, Singapore and other places. my country has also carried out research on related projects, and carried out demonstration projects in some provinces and cities such as Guangdong and Jiangsu. Construction, and put forward relevant domestic standards to accelerate the development of electronic toll collection technology. [0003] The ETC system uses RFID technology to complete the wire...
