The Reliability Research And Design Of Multifunctional Information Interaction Terminal In Networked Manufacturing

The bottom level information interaction terminal (IIT) in the networked manufacturing, especially in the shop floor usage, is one of the key equipments when networked manufacturing is employed. A multifunctional information interaction terminal (MIIT) in networked manufacturing is presented in the paper, by which information interaction, sharable ability and real-time in and between enterprises can be improved while cost is reduced. Therefore, the reliability design of terminal is important factor to whether to steady reliable work in long time and is pivotal technology of whole terminal system design to information terminal that worked in the foul enterprise workshop environment. The paper mainly studied in reliability analysis for MIIT in the networked manufacturing, and finally the reliability design is completed for information terminal.Firstly, the R&D of information interaction terminal and reliability design is discussed in the paper. After the system architecture of MIIT, including the hardware and software sub-architecture, is described, the architecture of its reliability design and reliability model is presented.Secondly, high temperature reliability, electromagnetism interference reliability, moist and dust reliability, vibration and impact reliability are mainly analyzed in allusion to the foul enterprise workshop environment and reliability model. The feeble factors are found out after the failure mode effect and criticality of information terminal are analyzed based on the reliability model of information terminal.Then, the reliability design of MIIT is finished by thermal design, electromagnetic compatibility design, and defenses against moist and dust design, defenses against vibration and impact design, software reliability design based on reliability factors of information terminal. The reliability is analyzed based on the reliability way.Finally, An application instance case study of the information interaction terminal in the paperless production engineering of manufacturing company is introduced then.
