Development of data acquisition and management system of warping machine based on Distributed Control System mode

To improve work efficiency of the preparation workshop in the textile industry,and to ensure acquisition of correct and real-time output and quality data of warping frames,in the local area network(LAN) environment,a data acquisition and management system for warping frames was developed via network technology,communication technology,database technology,and computer control technology,which can realize the remote on-line monitoring of production data and machine operating status.The system architecture,working principle and the main management functions were introduced,and the technical problems during the design process were solved by using transaction machinery,STL technology,etc.Meanwhile,real-time production data were fitted through using software filtering algorithms,and then the fitting results were compared and analyzed.a smoothing method with Newton difference was put forward to the collected signal.The system has been used in the textile industry,its core functions met the requirements of production management of the preparation workshop,furthermore,the real-time and correctness of production data were ensured.
