At present, there are various methods of moving vehicle detector and identification. the system we designed for traffic information makes use of the principle of electromagnetic induction and radio frequency identification the moving vehicle detector, which is based on inductive circular loop, detects the information of vehicle according to the inductive signal. the basic information including speed and go through time can be detected to analyze oscillator frequency
目前現行的車輛檢測與識別系統的種類繁多，本系統基於電磁感應理論和射頻識別技術，採用環形線圈作為數據採集傳感器，通過對振蕩器的頻率計數測量到車輛的通過、速度等基本信息，同時啟動射頻識別系統，使讀寫器與安裝在車輛上的非接觸ic卡進行無線通訊獲取通過車輛的類型和所屬用戶等數據，並將有關數據通過rs232串口送至上位機。 -
