Abstract: Based on Python programming language and big data, an automatic monitoring and early warning system is constructed, which can realize such functions as works monitoring, comprehensive early warning, visualization, parameter inversion, and real-time dynamic analysis etc. This automatic monitoring and early warning system can monitor in real time the pressure, displacement, and seepage water pressure of rock and soil mass during the construction process, automatically acquire monitoring data for remote wireless transmission, automatically store the data in a database, and use an Internet cloud platform for data sharing. The monitoring data can be used by the IA-BP algorithm module and the early warning and prediction module. The IA-BP intelligent algorithm performs inversion and intelligent prediction analysis on the monitoring data in the database, and makes comprehensive comparison and analysis between single threshold algorithm and IA-BP intelligent algorithm, thus achieving the purpose of early warning and prediction for engineering disasters.
