Abstract

The invention relates to an automobile running speed calculation method based on the ultrahigh frequency radio frequency identification. The method comprises the following steps: directional antennas are arranged right above a road, and are connected with an automotive electronic tag reader, and the automotive electronic tag reader and an automotive electronic tag on an automobile coated with the effective coverage area of the directional antennas are used for transmitting and receiving radio frequency signals; b, the electronic tag reader is used for capturing a plurality of radio frequency echo signals of the automotive electronic tag on the same automobile through the directional antennas at different times, and is used for obtaining identifying-reading positions of the automotive electronic tag according to the captured radio frequency echo signals, so as to obtain an automobile instant running speed through calculating; c, the automotive electronic tag reader is used for obtaining an automobile running speed through calculating according to the calculated instant running speed. By adoption of the method, the traffic running state regulation of vehicles on the road can be realized, and the calculation method is simple and convenient, high in accuracy, and strong in environmental adaptability.

Description

technical field [0001] The invention relates to a calculation and processing method of vehicle running speed, in particular to a calculation method of vehicle running speed based on ultra-high frequency radio frequency identification, which belongs to the technical field of traffic management. Background technique [0002] Since entering the 21st century, with the rapid development of my country's economy and the advancement of urbanization, the number of residents in Beijing, Guangzhou, Nanjing, Xi'an and many other large and medium-sized cities has reached 20 vehicles per hundred households, and my country is accelerating its entry into the automobile industry. society. However, the civilized driving behavior of the public and the awareness of social responsibility have not been improved at the same time. Uncivilized driving behaviors such as severe speeding, random lane changes and failure to obey traffic signals are common, resulting in increasingly serious urban traffic ...
