|
摘要
该文以大型粮食烘干机控制系统为研究对象,运用智能无线数据传输终端、可编程控制器PLC、人机界面HMI、温湿度传感器等,将采集到的信息传送到阿里云平台,可以通过手机APP、短信、以及电脑网页进行实时监控,烘干塔内进粮速度、风量、温度、含水率,为提高其动作响应速度及系统稳定性,搭建平台试验,以保障数据实时高效传输及系统稳定运行,为粮食干燥生产线控制系统网络化、智能化提供理论基础与技术支持。
Taking the control system of large grain dryer as the research object,Intelligent wireless data transmission terminal,programmable logic controller(PLC),human machine interface(HMI),temperature and humidity sensor,etc.The collected information can be transmitted to Ali cloud,which can be monitored in real time through mobile app,short message and computer web pages. In order to improve the response speed and stability of the system,the platform test is set up to ensure the real-time and efficient transmission of data and the stable operation of the system,and to provide the control system network for the grain drying production line. Intelligent and intelligent provide theoretical basis and technical support.
