摘要本项目利用可编程逻辑控制器（PLC），运用逐级引导的方式解决了大型停车场停车难的问题。为解决大型停车场停车难、取车难的问题提供了一套可行的解决方案。本系统涵盖车辆进出管理，车位智能引导，车位查询，应急事态控制等模块,保障停车场管理者实现实时监控.本系统利用红外探测技术,可靠猎取车位停车信息和车辆动态监测信息。信息将反馈给信息采集器，建立动态信息数据库，再由基于 PLC 的控制中心进行计算分析,可自动或人工对信息做出反馈产生引导信息，并将引导信息传给指示器，由指示器引导车主泊车及取车。从而提高停车场车位的使用效率，使得停车秩序得到优化,方便了车主泊车及取车。关键词:逐级引导; 可编程逻辑控制器（PLC）； 停车取车引导AbstractThis project uses programmable logic controller （PLC)， the use of step by step guide to resolve the problem of parking difficulty in large car park. To solve large—scale parking lots parking difficult， difficult to get vehicle to provide a method. Vehicles covered by the system management ， intelligent parking guidance and parking information, emergency situation control module, security managers real—time control 。 The system will use the composite vehicle detection technology ， reliable information access to parking spaces and vehicle dynamic monitoring information 。 Information will be fed back to the collector of information, the establishment of dynamic information array， and then by the PLC—based control center to carry out calculation and analysis, can be automatically or manually generated feedback information to guide the information, and guide the information to the indicator, the indicator guide car parking and access owners。 So as to enhance efficiency in the use of the parking spaces ， parking order has been optimized to facilitate the owners of vehicles parking and admission。Key words ： layer—by—layer hierarchical ； Programmable Logic Controller（PLC）...
