基于CAN总线的智能停车场通信系统

智能停车场是解决我国大中城市停车问题的有效手段。对停车设施进行合理地规划，对车辆停放进行有效地管理，提高城市交通系统的效率，是立体停车场迫切解决的问题。智能停车场管理系统采用先进技术和高度自动化的机电设备，将机械、电子计算机和自控设备以及智能IC卡技术有机地结合起来，通过电脑管理可实现车辆出入管理、自动存储数据等功能，实现脱机运行并提供一种高效管理。文中介绍了智能停车场控制系统组成及功能，给出了基于CAN（控制器局域网）总线智能停车场通信系统的设计与实现方案。该方案可以实现停车场车位管理动态智能化，所有车位状态都可实时监控，最大程度发挥集中调度和管理优势。

A Study on Intelligent Parking Lot Communication System Based on CAN Bus

Intelligent parking lot is an effective parking facility design reasonably, managing p pal transportation system are problems urgently parking way to solve parking problems in cities. Carryiing out the arking vehicles effectively, enhancing the efficiency of municineed to solve for three-dimensional parking lot. The intelligent lot management system uses advanced technology and high automated electromechanical devices to in- tegrate the machinery, the computer and the automatic control equipment as well as the intelligent IC card technology organically. Through the computer management automatic datum , storage can be realized, the ve- hicles in-out and the realization off-line running can also be realized, thus providing a kind of highly effective management service system. The paper introduces the constitution and main functions of intelligent parking lot, presents intelligent parking lot communication system based on CAN bus design and its realization. This design can also solve the problem of management of the parking lot dynamic intellectualization, all berth status can be monitored in real-time, thus obtaining the greatest degree of centralized dispatching and management advantage.
