Aiming at the lack of efficient monitoring means for the operating status of cranes in discrete manufacturing workshop,a set of discrete workshop crane data collection and monitoring system was proposed based on ultra-wideband (UWB) positioning technology.Based on UWB real-time positioning system combined with wireless sensor hardware,real-time positioning and load data of discrete workshop cranes were obtained,the abnormal UWB positioning data were processed smoothly,the information related to crane operation was output by constructing the spatio-temporal data fusion model.A visual monitoring and data statistics interface was built for a discrete workshop crane based on a hybrid development architecture.The practical application shows that the system has high data processing accuracy and good visualization effect,which can provide an efficient way to monitor the crane.
