Design method of laboratory equipment monitoring system based on industrial internet of things.

The IoT‐based monitoring system is used to collect, transmit, analyze, and monitor industrial data in real time, as well as to monitor and operate industrial field equipment. Reduced manufacturing costs, better managerial decision‐making, and increased production efficiency are all very important. The main research results are as follows: (1) The current development of the IoT technology at home and abroad is analyzed, the overall design of the laboratory equipment monitoring system with a three‐layer three‐dimensional architecture is proposed, and its working mode and functional composition are discussed. (2) A set of PLC control system with S7‐300 PLC as the core is designed by using the laboratory CS4000 process experiment device, which realizes the functional requirements of the laboratory equipment monitoring system on‐site monitoring. The intelligent IoT gateway suitable for the system is selected as the data collection and aggregation device of the system, which fully demonstrates the great role of the IoT technology in the monitoring field. (3) A laboratory remote monitoring platform that can remotely monitor experimental data is designed and its software and hardware functions are tested. The results show that all indicators have excellent performance. [ABSTRACT FROM AUTHOR]
