PLC停车场的自动控制 摘 要 智能建筑将是信息社会最重要的基础设施之一。停车场管理控制系统则是现代建筑中不可或缺的一部分。本次我们的设计的就是一个完整的小型工程项目，要求我们掌控控制系统的设计，安装、调试知识和技能。我们应用PLC作为现场控制器，对现场设备进行信号采集与控制。做到准确指示车辆进出，车辆进入时给与司机准确的车位数量与位置，车辆进入后，记录车辆，车辆离开时，减少车辆数量。车辆进出指示可完全由PLC作为中央控制处理，停车场空位指示可利用价格较不高的数码管显示 ABSTRACT With Chinas urban construction to speed up, and urban transportation demand is increasing, emerge in the car, a taxi parked behind, integrated management system medium low automatization, poor safety, humanization and running a series of problems such as low efficiency. This design aiming at these problems and insufficiency, combining the latest science and technology research, design a kind of technology is advanced, reliable performance, high degree of automation parking lot of intelligent management system. The system will be advanced computer processing technology, information technology, data transmission technology, automatic control technology, artificial intelligence and electronic technology, effectively integrated in the parking lot of intelligent management system, establish a kind in the role of regional on comprehensive, rapid and efficient parking intelligent management system, through adopts PLC technology for the design of parking management, car entering, record the amount when they leave, vehicle traffic, reduce the number of vehicles. Vehicle pass in and out instructions can completely by PLC as a central control processing, parking space instructions available price is not high, the digital pipe display to achieve parking intelligent, more efficient way.
