Design and Monitoring Operation Analysis of Automatic Control System for Nitrogen Production System
To achieve intelligent control of the nitrogen production control system and improve work efficiency,this paper designs a nitrogen production automation control system.The system is networked with S7-300 as the core and Profibus DP as the bus.It obtains voltage,current,power and other signals of high and low voltage switchgear through Modbus protocol,and adds an upper computer system to achieve digital monitoring and management,in order to real-time grasp the operation of the system.Through application,the monitoring system displays intuitively and can achieve overall automation control of the system,achieving unmanned operation,simple operation and maintenance,and high real-time performance.
