Design and Application of SPC System in Monitoring of Air Compressor Based SCADA Mode
Fu Chen · Coal Mine Machinery · 2013
Based on the design requirements of the project in Wuxi,the monitoring system by utilizing the statistic control algorithm(SPC) was demonstrated.The supervisory control and data acquisition(SCADA) mode was adopted in this system.The key technology and the topological structure of the system were illustrated specially in this paper.By running the system,it could display the change trends of the real parameters which directly reflected the working conditions of the air compressor.More importantly,the system could realize the functions such as the data store,data analysis,and abnormal data detection etc..When the judging rules were selected and the range of dates was specified,the configuration project could not only update the upper and lower limits of the SPC control chart,but also could alarm when the abnormal data appeared.This system could provide remote monitoring equipment maintenance personnel with the convenient,and it could provide some theoretical basis for the upper management in maintenance or scheduling for manufacturing equipment.
