Abstract: As an important part of railway operation, railway external environment management and control has many unresolved problems such as low level of informatization and lack of unified standards for data. In order to solve the above problems, this paper made a depth research on railway external environment management and control jobs and finally formulated a comprehensive set of railway external management and control solutions with a railway external environment management and control geographic information platform by using hybrid development model. Based on the chromium embedded framework and WebView development technology under hybrid App, it was designed and implemented the PC side railway external environment management and control subsystem and the mobile terminal railway surrounding environment intelligent inspection App respectively.The platform has implemented the functions of intelligent inspection of external hidden dangers of railway, management of "one map" of internal industry, account management, multi angle and all-round statistical analysis, etc., which improves the informatization and automation level of railway external environment management and control, reduces the working pressure of employees in railway external environment, and solves some problems in current railway external environment management and control.
