Design And Implementation Of Data Upload And Management System For Railway Precise Survey Network

At present,the amount of field observation data of high-speed railway precise survey network is huge and complex,and there are still some shortcomings in the existing railway survey field data management system,such as the system does not include the content,characteristics and management mode of railway precise survey network re survey,and there is no supporting integrated software for data acquisition and processing.Aiming at the shortcomings of the current railway survey data management system,this paper designs and implements the high-speed railway precise survey network data management system,and develops a supporting field data acquisition and processing integration software of electronic level based on intelligent terminal(level DMAS for short).Firstly,according to the development process of the software system,this paper analyzes the functionality,sub functionality and feasibility of the data management system of high-speed railway precise survey network and level DMAS,defines the development requirements of the software and system,and designs the corresponding business process and detailed structure.According to the design principle of top-down and gradual refinement,the detailed structure hierarchy diagram of software and system is designed.Secondly,the paper makes a detailed functional design of the software and system according to the demand analysis.Based on the user,function and authority,the data management system of high-speed railway precise measurement network designs the sub functions of each functional module of the system,and completes the database design of high-speed railway precise measurement network data management system.Level DMAS designs each functional module of the software based on the user’s use requirements.Then,according to the detailed functions of the designed software and system,the article uses coding technology to realize each functional module of the software and system,and explains the main implementation process of relevant functions.Finally,the paper tests the realization function of the software and system,designs the test case table of each function in detail,and verifies the realization function.Finally,the level DMAS is applied to the actual project,and the calculation results are compared with the adjustment software of China Railway Siyuan.The results show that the level DMAS has strong reliability.
