[Abstract]:Ground fissure is a kind of geological disaster, which often brings loss to people's life and property. This paper relies on the national important scientific research instrument development project and the special research project of the public welfare industry of the Ministry of Land and Resources. The research and development of distributed optical fiber monitoring information system for ground fissures is carried out, including the design of optical fiber monitoring network, the design of monitoring data processing, the design of monitoring data analysis and the development of data processing software. Construction and analysis software development of fiber optic monitoring network for ground fissures; The key technical problems such as distributed optical fiber data processing, optical fiber monitoring network construction and analysis are solved. This paper provides an information processing and analysis platform for distributed optical fiber monitoring of ground fissures. The main work and results of this paper are as follows: 1) summarize the current monitoring methods and shortcomings of ground fractures; The principle of distributed optical fiber monitoring technology is briefly introduced. This paper introduces the problems existing in the application of distributed optical fiber monitoring technology in the monitoring of ground fractures. It analyzes the basic characteristics of the ground fractures and the distribution characteristics of the ground fractures in plane and profile. The main points of research and development of distributed optical fiber monitoring information system for ground fissures are summarized. The general structure and development environment of distributed optical fiber monitoring information system for ground fissures are introduced in detail. The function structure and module partition of distributed optical fiber monitoring data processing subsystem and monitoring network construction and analysis subsystem are designed and realized. The design framework of each function module and the realization principle and method of each specific function are described in detail. This paper presents a distributed optical fiber data processing method-feature point compression algorithm .Y4) taking the fiber-optic monitoring of fissures in Hexiang Village, Zhutang Town, Wuxi as an example. The functions of the landing interface and each function module of the information monitoring system are verified. Finally, the advantages and disadvantages of several cloud image interpolation methods are compared and analyzed, and the application effect of the information system is analyzed. The applicability of the system is verified by combining the measured data.
