The invention discloses an electronic tag location information processing method and device which are applied to the field of intelligent transportation. The processing method includes the steps of obtaining, wherein electronic tag location information is obtained, and the location information includes coordinate information or / and angle information; screening, wherein the location information is screened according to the coordinate information or / and angle information, if not meeting the screening conditions, the location information is discarded, and if the screening conditions are met, transaction is allowed. The location information is screened through the coordinate information or / and angle information, the location information not meeting the screening conditions is discarded so that reflection, refraction and scattered signals caused by lane environment are rejected, then the vehicle electronic tag location accuracy is improved, the vehicle following interference and bypass interference problem is solved, and vehicle traffic efficiency is improved.
Description
technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and device for processing positioning information of an electronic tag. Background technique [0002] In the field of intelligent transportation, with the increasing number of vehicles, more and more vehicles begin to use the electronic toll collection (ETC, Electronic Toll Collection) system, and the demand for ETC lanes is also increasing. The utilization rate, traffic effect and speed index requirements of ETC lane mode are getting higher and higher. [0003] The positioning antenna obtains the signal of the electronic tag of the vehicle from the driveway, calculates the coordinates of the electronic tag, and immediately establishes the transaction system. This situation is often due to the lack of consideration of the complex factors of the driveway environment (ie reflection, refraction, scattering) and artificially installed antennas. installation error. ...
