Electronic fence based on 5.8 GHZ frequency band and building method

Abstract

The invention provides an electronic fence based on a 5.8 GHZ frequency band and a building method. According to the invention, the 5.8 G technology and the electronic fence technology in the ETC industry are combined; a plurality of 5.8 GHz signal antennas are arranged to form an electronic fence in a certain area, data communication is carried out through 5.8 GHz vehicle-mounted tags of vehiclesand the 5.8 GHz signal antennas, the vehicles are automatically recognized, and the vehicle-mounted electronic fence is suitable for payment and other automobile general service scenes. According tothe invention, common 5.8 GHz equipment of vehicles running on an expressway is utilized; a certain electronic fence area is delimited when the electronic fence is used for transaction; the vehicle-mounted pass voucher such as an OBU electronic tag or a CPC card on the vehicle is recognized, judgment and reminding of position information are completed or a transaction scene is added, electronization and intellectualization of an expressway can be improved, cost saving is facilitated, ETC service scenes are enriched, and the method has important significance in promoting ETC development.

Description

technical field [0001] The invention relates to the technical field of electronic fences, in particular to an electronic fence based on a 5.8GHZ frequency band and a construction method thereof. Background technique [0002] At the end of 2018, the total mileage of expressways in my country exceeded 140,000 kilometers, and expressway tolls basically achieved full coverage of ETC. According to the plan of the Ministry of Transport, by the end of 2019, the goal of canceling provincial toll stations and OBU installation rate of 90% will be achieved. The overall technical plan points out the technical route of canceling provincial border stations and adopting 5.8GHZ dedicated short-range communication technology. [0003] The expressway is currently changing from extensive to intelligent. With the advancement of technology, it is imminent to improve the intelligence of toll stations, service areas and even the entire road section. Electronic fence technology can be applied in qu...
