Research And Implementation Of Network Alarm System Based On Cross-media Retrieval

With the vigorous development of China’s real estate career, a large number ofmodern residential areas appear, and the district security issues are coming. Thedistrict security management is still depending on the video surveillance stage,basically there is no reasonable and perfect district safety management system todigitally manage the district, including the owners of the information collected, recordregistration of foreign staff out of the district.This project is about to resolve these issues, to provide a platform for theresidential property management and foreign registration to strengthen the district’ssecurity. With this system, all operating records will achieve real-time synchronizationwith the data from police system, the police will deal effectively with related caseswhen something dangerous happened, time is life, this system will provide time toaddress security issues and data security.Involved in the alarm-related content to offender information retrieval on theoperation, record information on offenders are relative to simple, the rapiddevelopment of information as the Internet, the personal information of its residues inthe network will be more and more. Cross-media technology can help the police getmore offender information of the offender.Based on the actual needs of the project we make a detailed needs analysis, and onthis basis, we complete the design and the development of residential securityregistration and alarm system. In this paper, the system will be introduced from thefollowing four aspects, the overall design of the system, the detailed design of thecommunication module, system security and performance optimization, the designbased on the semantics of cross-media retrieval system.Through the analysis of the actual needs of the project, the overall structure of thesystem is divided into three platforms, the property management platform, the recordregistration of foreign staff platform, the security alert platform. Star networktopology is accepted, according to the security, stability and efficiency requirementsof the entire system design. The system uses a star network topology, and therefore the communicationmodule become a most important part in the system design, the design of thecommunication module will be talked about in the next chapter based on the recordregistration of foreign staff platform, including the process of network communication,the design of communication protocol.Finally, in the security alert platforms, we complete the overall design based onsemantic-based cross-media retrieval techniques.Taking into account the environment and security of wireless networks, the systemuses BMP image compression and LZW data compression technology to ensure theefficiency of wireless networks. VPN technology based on CA-certified and firewallhardware measures to ensure the link access security. Using dynamic encryptionscheme to encrypt the application data, strictly ensure the security of the system. Thecombination of all factors into consideration the overall optimization of the system toensure system stability, security and efficiency.
