Research On The Key Techniques Of Fingerprint Entrance Integrated Control Platform Development

Fingerprint Entrance System(FES) is the organic combination of the computer control technology, fingerprint identification technology, intelligent cards technology and electronic lock technology. As the safety requirement is enhanced, there is an extensive application for FES. In this paper, we focus on platform development of the web-based fingerprint entrance integrated control and investigate systematically several relevant key techniques in it. In order to get a high performance for door request-response, System Architecture as well as scheduling optimization method and algorithm of FES are put forward. In addition, bridge-based heterogeneous component interoperation and mapping are built, as well as expanding of component interface semantic layer information based on the idea of design by contract. At last, with the help of XML and JMS techniques, heterogeneous data transfering and driving component model is designed. The technique and method suggested have been successfully applied to the development of web-based fingerprint entrance integrated control system.In the first chapter, paper discusses the FES's composition structure and existing problems, analyzing FES's optimization and scheduling algorithm in relevant fields, introducing component models, component interface expanding and heterogeneous component interoperation, summarizing the techniques' research status of heterogeneous data transfer and drive, The main content and the structure of this article is presented.In the second chapter, system architecture of FES is designed, scheduling and optimization principle are analyzed, as well as meta-door-control model is built. At the same time, scheduling and optimization goal and method are presented, FES scheduling and optimization algorithm is put forward, finally, the algorithm is put into practice to test it's performance.The third chapter studies the framework of syntactic layer, semantic layer and procotol layer in conponent interoperation and mapping, as well as the mapping methods in component interface syntactic layer. Bridge-based heterogeneous component interoperation is implemented. In addition, proposing expanding of component interface semantic layer information based on the idea of design by contract and building component interface semantic layer information expanding models.The fourth chapter builds heterogeneous data transfering and driving component models based on XML and JMS techniques, presenting architecture and diveing process of system models.In addition,design constraints of component diven and semantic description of component interface are put forward. Finally, component function design is implemented in detail.Based on the above four chapters, the fifth chapter describes the system design architecture and develops web-based fingerprint entrance integrated control platform. The technique and method suggested have been successfully implemented in the fingerprint entrance integrated control system.Conclusions are made in the sixth chapter, which summarizes the research results of this paper, and presents direction for further research.
