Study On Information Integration Pattern And Its Key Technique Of Automobile Manufacturing Line Based RFID

Because of its unique non-contact and can also identify multiple characteristics of the object, Radio Frequency Identification (RFID) technology is being increasingly used in supply chain, logistics, transportation, security and other fields. And because of the particularity of environment and production process of complexity, It is worth to study how to apply RFID technology into automotive production line application. The purpose of this disertation is to study the informaiton integeration pattern and related key techniques of RFID in auto production line.Based on the investigation the research history of RFID application in the world, especially the application in manufacturing industry and information integeration, the research object, content and ways and means have been put forward.Based on the basic process of automobile production,the RFID applications in automobile manufacturing and discrete manufacturing have been investigated using content analysis method. With research of information management of automobile production line, this disertation drawes that the body shop, paint shop and assembly shop are suit for RFID. Then the detail functions which are good for the automotive industry using RFID technology have been introduced.A new classify standard joint horizontal distribution with vertical integeration has been put forward. Then the distribution and integeration pattern of RFID system in manufacturing industry has been analyzed using content analysis method. With the investigation of detail functions which is good for the automotive industry using RFID technology, a RFID information integeration pattern in automobile produciton line combined horizontal function distribution with vertical multi-layers integeration has been brought forward. The key supporting techniques have also been discussedSome influential factors were put forward by combination of the application characteristics and access to relevant literatures. And find the main factors by control and technology filter. Then this desertation studys the significant degree and rule of single factor affect to the right read rate of RFID system.Through the comparison of comprehensive test method, simple comparison method and orthogonal test method, this disertation put forward orthogonal asymptotic optimization method to optimize the right read rate of RFID system which was influenced by several factors at the same time. A optimized scheme which got high read rate has been finded through experiment. The tests in the body shop and paint shop have also been carried out. Finally the advise how the readers and tags can be lacated in the automobile production line have been proposed.After the information management flows of automobile manufacturing process have been introduced, this disertation point out that RFID data can be stored in tags directly or in database indirectly. RFID data format has been defined according to the characters of RFID and the content has been discussed too. The proper communication manner fit for automobile produciton line has been advised. The network arrangement through middleware or network exchanger has also been discussed. Finally this disertation draw out that the RFID information can be integerated based on XML and the applications can be integeration based on web service technique.Finally, according to the information integeration pattern of RFID in the automobile production line, this disertation designed the structure of MES based on RFID. Then the funciton model, logical model and information flow model have been proposed. According to the system security of RFID system in the automobile production line, this disertation proposes a method which is to solve the security of RFID systems focusing the two aspects of the management system and technology supporting. Then this disertation gives the basic framework of constructing the RFID system security management system. On the technical level,the security of RFID system is divided into two security domains, which focuses on the security problem from the reader to application systems. This disertation stresses the need to apply intrusion detection to enhance the security of RFID systems. And it put forward a cluster algorithm framework to preceed pretreating partion which can reduce the computational complexity and get better performance in the intrusion detection. At the same time, an Immune_PSO algorithm framework has been introduced which can improve veracity.Some research findings of this disertation have been applied in the construction process of RFID system in the C Company, which obtained good results.
