Design of Measurement and Control System for Material Experimental Heating Furnace Based on Internet of Things Technology

The material experimental heating furnace is a very important thermal equipment to re alize the material heating process. In order to change the long-term on-site duty of the traditional heating experiment,the labor intensity and the exhaust gas are harmful to the health of scientific researchers. This article is based on the measurement of the internet of things based on the basic theory of control,the design includes a four-layer IoT measurement and control system including perception execution layer,network transmission layer,control service layer,and mobile application layer. The design composition and functions of each layer are discussed in detail. The article focuses on the composition of the software modules in the control service layer and mobile application layer. Finally,it discusses the data acquisition digital filtering algorithm in the internet of things system,the heating furnace digital incremental PID control algorithm,and the upper and lower communication algorithm design of the system.
