[Abstract]:Absrtact: because of the heavy workload of data collection in the traditional railway line, there are problems in the form of input and transformation of the paper data from the field to the internal computer. In order to improve the traditional paper operation mode of railway line dispatching data acquisition, this paper studies the "railway line dispatching data acquisition system based on mobile GIS", which integrates the functions of data preparation, analysis, processing and transmission. In this paper, with the application of mobile GIS technology, mobile computing technology, mobile database technology and other related theories, in order to improve the operational efficiency of railway line dispatching data acquisition, a new process and mode of railway line dispatching data acquisition using mobile GIS is put forward. It provides a new way to get rid of the traditional paper operation mode. According to the actual demand of the data acquisition process of railway line, the structure and function structure of the data acquisition system based on the mobile terminal are studied. On this basis, a "railway line dispatching data acquisition system based on mobile GIS" is established by synthetically using the Eclipse development platform and the mobile GIS secondary development component, and the advantage of the platform for mass off-line data processing is utilized. The problems of fluency and reliability of mass data processing in mobile terminal are solved, and the functions of pre-processing and off-line data acquisition are realized. The main function modules of the acquisition system are developed, including the data preparation module, the basic operation module, the data acquisition module and the data storage module. Finally, the problems found in the system design are summarized, and the future work is prospected. The system meets the needs of the railway line data acquisition project. It has the functions of displaying, adding, querying, editing and so on. At the same time, it can process and save the data with embedded spatial database technology, and realize the seamless data sharing.
