Research on Information Integration Mode and Key Technologies of Automobile Production Line Based on RFID:

Radio Frequency identification (RFID) technology has been widely used in many fields such as supply chain, logistics, transportation and anti-counterfeiting because of its unique non-contact property and the ability to identify multiple objects simultaneously. Because of the particularity of the automobile production environment and the complexity of the production process, how to apply RFID in the automobile production line is a very worthy of study.

This paper mainly studies the RFID information integration mode and key technologies in automobile production line. Firstly, the paper introduces the research background and the proposal of the research problem, and summarizes the application research of RFID at home and abroad, especially the application of RFID in manufacturing industry and the relevant research status of information integration. On this basis, the research objectives, specific research contents and research methods of the paper are proposed.

Introduces the RFID technology and auto production, on the basis of the basic flow, the paper adopts content analysis method the application of RFID in automobile manufacture and discrete manufacturing link and application function of statistical investigation, combined with deep investigation on the present situation of information management of auto production line, points out that the current RFID application in automobile production line is suitable for the link is welding, painting and assembly, And put forward the detailed application function of RFID in the corresponding link of automobile production line.

Based on the existing research results, this paper proposes an improved classification method of horizontal distribution deployment and vertical integration distribution, and investigates the deployment and integration mode of RFID in the manufacturing industry by using content analysis method. Combined with the analysis of the application link and application function of RFID in the automobile production line, This paper proposes a RFID information integration model for automobile production line with horizontal and vertical multilayer functions. On this basis, the integration framework of RFID system and MES is proposed. After Z, the key technologies supporting the operation of RFID information integration mode of automobile production line with horizontal distribution and vertical multilayer function are simply analyzed.

Based on the analysis of the main factors affecting RFID reading and writing performance, this paper carried out single factor test and multiple factor orthogonal test for controllable factors. Single factor test was used to analyze the significance degree and influence rule of the main influencing factors on the reading performance of RFID system. In view of the main influencing factors proposed, the advantages and disadvantages of comprehensive test method, simple comparison method and orthogonal test method are compared and analyzed, and the Z-optimal combination level of multiple factors affecting RFID reading performance is proposed by orthogonal asymptotic optimization test.

On this basis, a variety of tags are selected to be applied and tested in welding and painting production lines. According to the test results, the layout scheme of RFID tags and readers in automobile production lines is proposed. This paper puts forward the information processing flow of RFID system in automobile production process through research, and analyzes that RFID data in automobile production line can be stored directly by tag and stored by background data. Based on the analysis of the characteristics of RFID data, this paper puts forward a form of RFID tag data content, and discusses the specific content of RFID data management. In this paper, an RFID data communication method suitable for automobile production line is proposed, and two reader networking methods, RFID information integration based on XML and RFID application integration based on Web service technology are proposed. In the last part of this paper, the RFID-based MES system framework is constructed, and the RFID-based MES function model, physical model and information flow model are studied. Based on the analysis of the security requirements of RFID system in automobile production line, this paper puts forward to solve the security problems of RFID system from two aspects: management system and support technology. The basic framework of RFID system security management system is given. In technology will be the security of RFID system is divided into two security domain, the key research by the reader to application system security problems, put forward the RFID system, introduced the intrusion detection technology, and from two aspects of the study on improvement of intrusion detection, a clustering algorithm is used for data preprocessing in order to reduce the computational complexity and improve the detection efficiency; Secondly, the immune particle swarm evolution algorithm is used to directly improve the feature selection to improve the detection accuracy. The framework models of the two methods are given after Z. The research results of this paper have been partially applied in the construction process of RFID system of production line of C Automobile Company, and achieved certain effects.
