Abstract

The invention relates to the technical field of foundation pit underground water level monitoring, and discloses a method for automatically monitoring the foundation pit underground water level by utilizing laser reflection, and the method comprises the following steps of: S10, installing a water level pipe; S20, setting observation time and sending the observation time to an acquisition terminalby a remote monitoring terminal, and controlling a laser ranging structure to be started according to the observation time by the acquisition terminal; S30, transmitting laser by the transmitting endof the laser ranging structure, reflecting the laser by a laser reflection target, and receiving the laser by the receiving end of the laser ranging structure, thus obtaining laser information; S40, sending the laser information to the acquisition terminal by the laser ranging structure; S50, analyzing the laser information by the acquisition terminal to obtain current water level information; andS60, sending the water level information to the remote monitoring terminal by the acquisition terminal. According to the method for automatically monitoring the foundation pit underground water levelthrough laser reflection, the distance is directly measured according to the laser ranging structure, the water level height is obtained, and the method is more direct and accurate.

Description

technical field [0001] The patent of the present invention relates to the technical field of foundation pit groundwater level monitoring, in particular, to a method for automatically monitoring the groundwater level of foundation pits by using laser reflection. Background technique [0002] The monitoring of the groundwater level is one of the main contents of the foundation pit engineering monitoring project. The rapid loss of the groundwater level will have a great impact on the surrounding buildings and roads. The monitoring of the groundwater level also has an early warning effect on the collapse of the foundation pit. [0003] At present, the monitoring of groundwater level in foundation pits mainly adopts traditional manual monitoring, while the existing automatic monitoring methods all adopt pressure-converted vibrating wire or pressure-sensitive digital sensors. [0004] However, the above-mentioned detection method is an indirect measurement method, which will lead ...
