基于PLC的设施农业反渗透水处理系统设计

为改善设施农业种植人员对设施农业自动化设备的操控问题,设计依据设施农业反渗透处理设备的整体运转逻辑,将大部分需要人为操作的动作进行编程。PLC通过对预置参数和现场采集的工艺参数进行比对,根据预设定的阈值执行和调整现场各主控设备的状态。同时人机界面将二元图形画面更替为更容易理解的三维及动态画面,利用SolidWorks软件进行三维效果图形的生成和制作,并储存于人机界面中,通过与PLC通信完成现场工艺数据的采集,在组态软件中编辑脚本调用制作的图形模拟现场设备的运行状态,实现了全参数的可视化、动态化。通过推广试用表明,该方法极大地降低了设备运行对操作人员的依赖,让设备运行操作变得简易。

In order to improve the control of facility agriculture automatic equipment by facility agriculture planting personnel,this design programs most actions that need human operation according to the overall operation logic of facility agriculture reverse osmosis treatment equipment.By comparing the preset parameters with the process parameters collected on site,PLC executes and adjusts the status of each main control equipment on site according to the preset threshold.At the same time,the man-machine interface replaces the binary graphic picture with a more understandable three-dimensional and dynamic picture.The three-dimensional effect graphics are generated and produced by SolidWorks software and stored in the man-machine interface.The on-site process data is collected through communication with PLC.The script is edited in the configuration software to call the produced graphics to simulate the operation state of the on-site equipment.The visualization and dynamic of all parameters are realized.The popularization and trial shows that this method greatly reduces the dependence of equipment operation on operators and makes equipment operation simple.
