摘要
基于射频技术提出了一种新型车牌自动识别装置的设计思路,并详细阐述了该装置的工作原理、硬件电路及软件的设计。利用单片机控制射频读写模块,读取车牌的数据信息,可以通过LCD显示读取的信息,根据读取的信息来识别车牌。此外,可根据需要修改读取的数据信息。适用于真假车牌的鉴别,各种停车场所的车辆管理等。该装置具有识别的准确度高、可靠性好、抗干扰强、成本低、便于携带等特点。
A new design idea of automatic license plate recognition device was presented, based on radio frequency technology. The working principle of the device and its hardware circuitry and software program design were described in detail. The radio frequency module to read the license plate data was controlled by the Single-chip microcomputer ,and the data was displayed on LCD. Based on the reading data information , the Single-chip microcomputer could identify the license plate. In addition,the data can be modified and stored depending on the users＂ needs. The equipment could be applied to identify fake license plate and the vehicle could be managed by the equipment in various parking. The device carried some characteristics such as highly recognition accuracy, reliability, strong anti-interference, low cost, and easy to carry.
