Design And Research Of Human-machine Interaction System For Rapier Loom

"Made in China 2025" strategy has pointed out the direction for the development of China's traditional manufacturing industry.As the top-level control part of production equipment,human-machine interaction system plays an important role in improving the intelligent level of manufacturing industry.At present,there is still a certain gap between the research of loom human-machine interaction system and the first-class foreign textile enterprises,mainly manifested in the lack of comprehensive functions,single human-machine interaction,and lack of effective methods for fault maintenance.In view of the above shortcomings,dissertation studies and designs a rapier loom human-computer interaction system which can realize two kinds of interaction modes in industrial field and remote network,and has comprehensive functions.Mainly from the following aspects of research and Design.Firstly,the modules of the whole loom control system are explained,and the main technological principles,fault types and solutions of rapier loom are analyzed and summarized.Through the analysis of functional requirements,the overall design scheme of human-machine interaction system is defined.The whole system is divided into two parts:on-site and remote.The touch screen is selected as the main carrier of the on-site system,and the related configuration technology and expert system are used to realize the fault diagnosis and other functions.The B / S architecture is used as the communication architecture of the remote system,and the communication mode between the cloud platform and other modules in the remote system is explained.Secondly,the design and research of the field system is completed.The realization steps and the interface planning and design of various functional tasks of the field system are clarified.MCGS Pro is used to complete the design of interface,database and script program.The method of expert system and fault tree diagnosis is studied,and the function of fault diagnosis is realized by configuration technology.RS485 module is used to realize the communication between the control module and the touch screen.According to Modbus RTU communication protocol,the relevant slave program is designed and developed.Thirdly,the design and research of remote system is completed.The dissertation determines the selection and configuration of cloud platform in remote system.The installation and running environment of Redis database and Nginx server are completed.HTML5 and other front-end technologies are used to design the client interface to meet the functional requirements.Communication protocols such as PCP / IP and HTTP are used to complete the information exchange between various parts of the remote system.Wireless module is used as the client of TCP,and the program of wireless module is designed and developed.Finally,the data transmission experiments of the field and the remote system,the data storage and reading of the server database,the field human-computer interface and the actual use of the remote web client were tested in the laboratory and the industrial field.Through the test,it is verified that the human-computer interaction system has achieved the design expectation,and can meet the needs of field and remote interaction and fault diagnosis.
