SCADA systems widely used in the industrial field have multiple implementation methods.This paper intro-duces a SCADA system based on mobile communication networks that is suitable for various terminal types.The main sta-tion consists of cloud server,database,and SCADA software.The terminal station is composed of on-site data source and data transfer unit.The on-site data sources include various types such as programmable logic controllers,data collectors,and configuration software.They use standard communication protocols to connect to the Internet through data transfer units and establish communication with the main station,achieving data collection from the main station to the terminal station.The system has the characteristics of high reliability,low cost,and easy scalability,which has reference value for the scheme selection and technical implementation of SCADA system construction.
