The invention relates to the technical field of license plate recognition, and discloses a license plate recognition system, which comprises an industrial personal computer, the output end of the industrial personal computer is electrically connected with the input end of a DSP processing chip, the input end of the DSP processing chip is electrically connected with the output end of a geomagnetic induction coil, the input end of the DSP processing chip is electrically connected with the output end of a vehicle recognition camera, and the output end of the vehicle recognition camera is electrically connected with the output end of the vehicle recognition camera. The output end of the industrial personal computer is electrically connected with the control end of the gate bar, the output end of the industrial personal computer is electrically connected with the input end of the screen, and an independent DSP processing chip is arranged on the industrial personal computer to carry out license plate recognition operation, so that the special DSP processing chip is used as an operation core and is independent of a computer system, and the operation efficiency is improved. The method does not occupy computer CPU and memory resources, guarantees the recognition speed and recognition accuracy of the license plate, and is not interfered by the stability of a computer system. And the system is very suitable for all-weather operation in different working environments, and has extremely high system stability and environment adaptability.

    本发明涉及车牌识别技术领域,且公开了一种车牌识别系统,包括工控机,所述工控机的输出端与DSP处理芯片的输入端电连接,所述DSP处理芯片的输入端与地磁感应圈的输出端电连接,所述DSP处理芯片的输入端与车辆识别摄像机的输出端电连接,所述工控机的输出端与闸栏的控制端电连接,所述工控机的输出端与屏幕的输入端电连接,通过在工控机出设置有一个单独的DSP处理芯片对车牌识别的运算,从而实现了用了专用的DSP处理芯片作为运算核心,独立于计算机系统,完全不占用电脑CPU和内存资源,保证了车牌的识别速度和识别准确率,并且不受计算机系统稳定性的干扰。非常适宜于不同的工作环境全天侯运行,具有极高的系统稳定性和环境适应。
