Abstract: Horizontal displacement monitoring plays an important role in rail transit engineering.With the development of mobile Internet and smart devices,especially their applications in horizontal displacement monitoring,real-time monitoring data retrieval and data security issues become increasingly important.In this paper,a real-time horizontal displacement monitoring mobile application for Android device is introduced.With bluetooth and network communication functions built in Android device,the monitoring equipment,the Android device and the monitoring information service platform are connected together,which ensures real-time monitoring data retrieval.On the other hand,embedding with data encryption algorithm ensures the data security.Applying the developed software in practical rail transit projects shows that the software can collect and process monitoring data in real time which improves the monitoring efficiency.By encrypting monitoring data,the data security issue can also be resolved.

Key words: Android, rail transit engineering, horizontal displacement, real-time monitoring, data encryption
