基于物联网与PLC的智能立体停车模型设计与应用

Design and Research of Stereo Garage Model Based on Internet of Things Technology and Programmable Logic Controllers

针对城市老旧小区停车难的问题,设计了一款基于物联网和可编程控制的立体停车库模型,能够充分利用停车位的上层空间提供更多车位,该模型采用西门子1200的可编程控制器(PLC)作为控制单元,采用多种传感器检测车库车辆和车位信息,并综合物联网技术将该信息上传到云服务器中.该系统模型在触摸屏上建立组态界面,可以实时监控系统运行状态,并将用户需求反馈给PLC,控制机械装置运动进行自动存取车.同时用户可以使用手机APP远程随时随地访问云服务器进行预约存取车,极大方便了用户的使用.该模型能模拟现实中自动存取汽车的升降、横移,实现预期效果,为后续解决老旧小区停车难提供借鉴与参考.

A stereo garage model based on the Internet of Things and programmable logic controllers is designed to solve the parking problems in old urban communities by making full use of the upper space of the parking space to provide more parking spaces.The model uses Siemens 1200 programmable controller(PLC)as the field controller,uses a variety of sensors to collect and detect garage vehicle and parking space information,and integrates Internet of Things technology to upload the information to the cloud server.The model uses a touch screen to design the configuration screen to monitor the system operating status in real time,feedback user needs to the PLC,and controls the movement of the mechanical device to automatically stored or retrieved cars.At the same time,users can use the mobile APP to remotely access the cloud server anytime and anywhere to make reservations.The model can simulate the lifting and lateral movement of automatically stored or retrieved cars in reality,achieve the expected results,and provide some reference for solutions to parking difficulties in old communities.
