The data processing module is connected with the distance measuring module. The distance measuring module corresponds to the surface of the foundation pit. A guide rail is arranged above the foundation pit and along the edge of the foundation pit. A mobile vehicle is arranged on the guide rail. A displacement sensor is installed on the mobile vehicle. The distance measuring module is installed on the mobile vehicle. The displacement sensor is connected with the data processing module. The data storage module stores the displacement value of the displacement sensor when storing the distance value. The data processing module is connected with a display module for displaying the displacement value and the distance value. The patent moves the mobile vehicle along the guide rail.
