?OTDR Optical Fiber Intrusion Detection's Researching And Software Design

With the rapid development of China's social economy and science and technology,military capabilities continue to increase,the energy industry,military fields and civil aviation areas also will be rapid development.The state's security requirements in all areas are becoming more stringent.Accompanied by the various areas of security protection technology needs are getting higher and higher.So the need for more secure and reliable security detection system to protect the safety of the industry.In view of this situation,compared with the traditional detection technology,better performance of optical fiber vibration early warning technology began to develop rapidly.?OTDR optical fiber intrusion detection system is based on the optical fiber vibration warning technology security monitoring system,the optical fiber within the fiber as a sensor,the protection of the assets of the surrounding intrusion events uninterrupted monitoring,category analysis and judgment,precise location,pre-warning,and timely Take measures to avoid losses.Based on the ?OTDR optical fiber intrusion detection system,the paper analyzes the characteristics of the system,and designs the ?OTDR optical fiber intrusion detection software in combination with the practical application and the customer's requirement.The software mainly includes six functional modules,namely:customer login,intrusion source alarm,parameter settings,file transfer,historical query and software encryption.The design and application of the three-level filtering method and the design and application of the software encryption system are introduced in this paper.These three designs improve the performance of the software.The intrusion detection method can effectively reduce the false alarm rate of the system while satisfying the real-time requirement of the system.Map alarm three-level filtering method to solve the problem of useless alarm data too much,reducing the storage of the database.The software encryption system uses the USB software encryption key technology,and introduces the concept of data flow transmission,the use of streaming media in the process of transmission,a fundamental solution to the theft of system files,greatly improving the security of the software.
