气动垃圾回收系统阀门控制策略研究

Valves Control Strategy of Pneumatic Waste Collection System

为实现气动垃圾回收系统的实际应用,阀门控制策略方案的设计与验证十分重要;分析系统运行过程,抽象出系统运行参数并建立数学模型,确定系统"自下而上"的基本控制逻辑;设计分析了以单层循环式排空策略为代表的三种控制方案,确定单元式阀门控制为最优选择,并以数值模拟的方式对研究内容进行了验证;该方案使得系统执行排空动作时阀门开启次数较少,系统设备成本降低,安全性提高。

To achieve practical application of pneumatic waste collection system,the design and test of valves control strategy are important.Analyze the working process of the system,try to present operational factors of system and create the numerical model.The project defines the essential control strategy as“from the bottom up”.There are three control schemes including single loop evacuation strategy and the three layers unit is the best,which can be proved by numerical simulation.In this way,the system can achieve less valves opening,less system equipment cost and more safety.
