Monitoring and early warning system for surface displacement around strip mine

The utility model provides a surface displacement monitoring and early warning system around a strip mine, which comprises a data monitoring and processing module, a data communication module, an early warning module and a sensor module, and the sensor module acquires surface displacement information in monitoring points of a gas power plant around the strip mine at a certain frequency. The sensor module is used for acquiring earth surface displacement information and sending the earth surface displacement information to the data monitoring and processing module through the data communication module for processing, and the data monitoring and processing module sends an adaptive acquisition frequency control instruction according to the earth surface displacement in the earth surface displacement information so as to change the acquisition frequency of the sensor module. When the earth surface displacement is large and is about to exceed or already exceeds an early warning set value, the acquisition frequency
