Robot system for monitoring horizontal displacement of foundation pit deep layer and automatic monitoring method

Abstract

The invention provides a robot system for monitoring horizontal displacement of a foundation pit deep layer and an automatic monitoring method. The robot system comprises a toothed guide rail and a robot driven by a motor; the toothed guide rail is installed in an inner guide groove of an inclinometer tube; the robot is provided with the motor, a gear combination, a dynamic tilt angle sensor, a tooth number counter, a data acquisition and storage module and a data transmission module; the gear combination is matched with the toothed guide rail, the gear combination is driven by the motor to operate, so that the robot ascends and descends in the inclinometer tube, and the dynamic tilt angle sensor records angle values of the robot at different positions; the tooth number counter positions and records the up-down crawling distance of the robot; data is stored in the storage module; the data transmission module transmits the data to a handheld mobile equipment terminal. According to the robot monitoring system provided by the invention, cable-free measurement is realized, and the robot system is portable; all data acquisition is automatically completed by a measuring device, so that errors caused by manual measurement are reduced, and the efficiency and the accuracy are improved.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a robot system and an automatic monitoring method for monitoring the deep horizontal displacement of a foundation pit. Background technique [0002] In modern foundation pit engineering, the excavation of foundation pits tends to be large and deep, and the deep horizontal displacement of foundation pits is an important factor to measure the safety of foundation pit engineering. Therefore, higher requirements are put forward for the monitoring of horizontal displacement of deep foundation pits . [0003] At present, the traditional manual measurement method is mostly used in China. The principle of inclinometer is to measure the inclination angle change of the inclinometer tube installed in the enclosure structure or soil by the inclination sensor. The displacement is obtained through accumulation. [0004] Most of the inclinometers currently on the market mainly use a structure in wh...

AI Technical Summary

Problems solved by technology

[0005] 1. The measurement process requires two people to cooperate with the operation, there is no automatic measurement function, and the measurement efficiency is low, time-consuming and laborious;

[0006] 2. The diameter of the cable is relatively thick, generally 10-12mm; the interior contains multiple strands of steel wire rope, and the cable is heavy and inconvenient to carry;

[0007] 3. The position of the probe is determined by visual inspection, and the positioning error is large, which affects the accuracy of the measurement

The automatic inclinometer can better solve the problems of manual measurement, but the cost of the instrument is high, the amount of on-site instruments is large, it cannot be widely used, and the installation workload of the instrument is relatively large
