Abstract: In view of problems that it cannot find potential fault real-timely, and has low equipment utilization rate and production efficiency, a data analysis system of mine electromechanical equipments was designed. The system uses iHistorian server to store data of each collection point of mine electromechanical equipments, analyzes the data from five aspects of basic data, reliability, energy consumption, efficiency and pre-warning, and stores the results in database of SQL Server for using by client through Web server. The actual application shows that the system can feedback running status of mine electromechanical equipments real-timely, and ensure real-time analysis and pre-warning of safe and highly efficient running for running data of mine electromechanical equipments.
