基于CAN总线的汽车车位智能管理系统的设计

Design of Intelligent Management System Using on Parking Spaces Based on CAN Bus

为满足当前汽车车位实时管理的需求,对比了CAN总线和RS485总线,最终选择CAN总线来实现汽车车位的实时智能管理系统。设计了两层CAN总线网络系统,系统中第一层CAN总线网络检测车位的车辆信息,通过第二层CAN总线网络把信息传输至上位机,由上位机进行信息识别,并将识别结果通过两层CAN总线网络传送至对应车位并进行相应处理。系统采用单片机为控制器,能够实时有效地管理11881个车位。

In order to meet the needs of real-time management of current car parking spaces,the CAN bus and RS485 bus are compared,and finally the CAN bus is selected to realize the real-time intelligent management system of the car parking space.A two-layer CAN bus network system is designed.The first layer CAN bus network in the system detects the vehicle information of the parking space and transmits the information to the upper computer through the second layer CAN bus network.The information is identified by the host computer,and the recognition result is transmitted to the corresponding parking space through the two-layer CAN bus network and processed accordingly.The system uses a single-chip microcomputer as a controller,which can effectively manage 11881 parking spaces in real time.
