Truck counting method based on radio frequency identification

Abstract

The invention discloses a truck counting method based on radio frequency identification. The truck counting method comprises the steps that step one, an electronic tag is arranged on an access vehicle, and a counting module and a storage unit are integrated in the electronic tag; step two, when a weighing system identifies that weight of the vehicle exceeds the weight limit value, a first trigger signal is generated, or a second trigger signal is generated; step three, when the first trigger signal is generated and the cumulative value is an even number, accumulative counting is performed by the counting module, and when the second trigger signal is generated, accumulative counting is not performed by the counting module; step four, when the vehicle enters the access port and the second trigger signal is generated and the cumulative value is an odd number, accumulative counting is performed by the counting module, and when the first trigger signal is generated, accumulative subtraction is performed by the counting module; and when the cumulative value is the even number and the vehicle enters the access port, the counting module does not actuate. The technical problem of low vehicle counting efficiency is solved so that counting accuracy is enhanced.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a method for counting trucks based on radio frequency identification. Background technique [0002] The radio frequency tag is the physical carrier of the electronic product code (EPC), which is attached to the trackable item and can be circulated globally and identified, read and written. RFID (Radio Frequency identification) technology, as a key technology to build the "Internet of Things", has attracted people's attention in recent years. RFID technology originated in the United Kingdom and was used in World War II to identify enemy and enemy aircraft. It was commercially used in the 1960s. RFID technology is an automatic identification technology. The U.S. Department of Defense stipulates that after January 1, 2005, all military supplies must use RFID tags; Counterfeit medicines. A series of actions such as the application of RFID technology in Walma...

Problems solved by technology

[0012] In view of the above technical problems, the present invention discloses a method for counting trucks based on radio frequency identification. An electronic tag carrying vehicle information is installed on the vehicle, and a counting module is installed in the electronic tag. The system and weighing system count the vehicles and store the cumulative value in the electronic tag, which solves the technical problem of low efficiency in counting vehicles, improves the accuracy of counting, and saves time
