摄像头识别的智能车硬件系统设计

Design of intelligent car hardware system with camera identification function

智能车在探测、救生等方面具有广阔的应用前景,针对图像识别智能车缺乏稳定的运行状况,提出一套完整的硬件设计思路。该系统以飞思卡尔公司的MC9S12XSl28单片机为核心控制器,设计智能车整体硬件系统框架,并详细给出了智能车电源单元电路、电机驱动模块、舵机控制的电路图。通过分析路径信息采集、速度信息采集、以及对输入/输出模块与单片机连接,说明如何构成一个闭环反馈系统。以上硬件系统应用在智能车中得到了稳定的运行。

The intelligent car has a broad application prospect in the exploration, life-saving and other aspects. A hardware design idea is presented because the image recognition intelligent car has no stable operating status. Freescale MC9S12XS128 mi- crocontroller is taken as a core controller of the intelligent car hardware system. The frame of the smart ear overall hardware sys- tem is designed. The power supply unit circuit, motor driver module, steering gear control circuit diagram of the intelligent vehi- cle are offered in this paper. A method to constitute a closed-loop feedback system is described by analyzing the path informa- tion acquisition, speed of acquisition, and the connection of input and output modules with SCM.
