Real-time Monitoring Of Large-scale Rotary Kiln Running State Computer System Hardware And System Monitoring Software

Rotary kiln is the key equipment in the production of metallurgy, cement and material of fire-fast. It is the statically indeterminate system with over load, large torque and multi-supporting. Ensuring rotary kiln operate safely and efficiently is the key way for corresponding enterprise to increase economic benefit. The operating axes of rotary kiln are the prominent factor of influencing the machine operating state. People are required to know and analyze the operating axes of rotary kiln in time in practice, in order to adjust and maintenance it in reason. So The Great Wall Aluminum Corporation of China bankrolled for studying the microcomputer real-time monitoring system of large-scale rotary kiln and commissioned Central South University to develop it.Based on analyzing and comparing the status quo of the monitoring system of rotary kiln, this paper brings forward a new method of monitoring the operating status of rotary kiln. It analyses the system-error and the configuration and demonstrate the feasibility in detail. In the design of hardware configuration it analyzes the principle and speciality of the tailor-made eddy current transducer and PCI-1713 analog input card and the multilevel supervisory network. In addition, in the design of software configuration it analyzes the realization of the high-speed data sampling program and intelligent information processing and monitoring. At last it introduces function of sbftware of systems analysis in brief.The operation demonstrates that the brand-new monitoring method of the monitoring system can acquire the operation axis of large-scale rotary kiln by rule and line on the operation position, and it is a break-through in real-time monitoring method. It is facility to mount and maintain, reliable to operator, and precise to monitor. The monitoring software has abundant functions and kind interface.
