Bus arrival detection method and system based on active RFID technology

Abstract

The invention provides a bus arrival detection method based on an active RFID technology. Two RFID readers and an electronic bus-stop board main control unit are mounted on each bus, wherein the two RFID readers include a first RFID reader and a second RFID reader; an RFID electronic label is mounted at the outer side of the body of each bus. The bus arrival detection method based on the active RFID technology includes the following steps that 1, the bus pulls in, and the first RFID reader reads electronic label data of the RFID electronic label; 2, the second RFID reader reads the electroniclabel data of the RFID electronic label; 3, the electronic bus-stop board main control unit is used for receiving the electronic label data read by the first and second RFID readers and conducting algorithm processing on the electronic label data, and therefore which station and which direction the bus is located at are judged. The invention further discloses a bus arrival detection system basedon the active RFID technology. The bus arrival detection method and system based on the active RFID technology has the advantages of being low in power consumption and comprehensive cost, not influenced by rainy and foggy weather and stable in performance and not generating network costs such as SIM card communication flow costs.

Description

technical field [0001] The invention relates to the field of electronic bus stop board systems, in particular to a bus arrival detection method and system based on active RFID technology. Background technique [0002] Electronic bus stop sign system is an important part of public transportation construction, mainly used for bus arrival signal detection and calculation of passenger waiting time. The traditional electronic bus stop sign system usually uses vehicle-mounted GPS to realize vehicle station announcement, sets up electronic stop signs at each bus stop, and puts vehicle-mounted GPS+GPRS into each bus. The system is divided into a vehicle-mounted part and a bus station part. The vehicle-mounted part receives and processes satellite information, and transmits the data to the bus station through a wireless transmission module. The bus station processes the received information and displays it on the bus. On the stop sign, passengers can always know the current location...
