Embodiment 2

[0045] The data processing center performs filtering, amplitude domain, time domain, frequency domain, and correlation analysis on the data collected after transmission, and can perform preprocessing and analysis based on the previously collected data;

[0046]According to the processed and analyzed data, the corresponding warning response level is determined. The warning response is divided into four levels. Different warning measures are taken according to different warning levels, and real-time warning is performed on relevant key parameters.

[0047] When reaching the third or fourth level of early warning, early warning information is sent through PC terminal, APP terminal, SMS, email, etc., so that preventive measures can be taken in time;

[0048] When the first- and second-level warnings are reached, the warning information will be sent through the PC terminal, APP terminal, SMS, email, etc., and the alarm will be issued through the on-site sound and light alarm device ...

Embodiment 3

[0050] The implementation method is as follows:

[0051] S1: Set up surveying robot and GNSS equipment reference station;

[0052] S2: Build the connection between the survey robot, the GNSS equipment base station and the cloud database connection;

[0053] S3: measure settlement data and upload displacement data;

[0054] S4: Analyze the data level and make early warning of the corresponding level.

[0055] In S1 based on the implementation method:

[0056] Both the surveying robot and the GNSS base station are erected on the top of the slope of the foundation pit and the top of the enclosure structure. The distance between the deformation observation points is less than 20m, and the installation material of the deformation observation points is an L-shaped small prism;

[0057] And the collection frequency is every 30 minutes / time, and the collection frequency is increased in case of emergencies.

[0058] In S2 based on the implementation method:

[0059] The measuremen...

Abstract

The invention relates to a large-area deep foundation pit intelligent monitoring system and an implementation method, the large-area deep foundation pit intelligent monitoring system comprises a measuring robot and a GNSS system, the measuring robot and a GNSS device base station are arranged at the top of a foundation pit slope and the top of an enclosure structure, and the GNSS system is composed of a cloud database, a data processing center and an early warning analysis system; the measuring robot and the GNSS system monitor data of foundation pit deformation monitoring points, the data are transmitted to the cloud database through GPRS / 3G / 4G, the data processing center processes and analyzes the collected data, determines the early warning level according to the processed and analyzed data, and immediately sends out an early warning signal when an early warning index is obviously changed. According to the invention, real-time observation, early warning implementation and intelligent management can be realized, the effect on the large-area deep foundation pit is obvious, the monitoring precision is high, the monitoring efficiency is high, and the monitoring cost is low.

Description

technical field [0001] The invention relates to the technical field of foundation pit monitoring, in particular to a large-area deep foundation pit intelligent monitoring system and an implementation method. Background technique [0002] Due to the complexity of the underground soil properties, load conditions and construction environment, the deep foundation pit project can easily lead to the gradual structural instability and deformation of the structure and the surrounding environment. Timely analysis of on-site construction monitoring data, comprehensive grasp of changes in structure and surrounding environment, in order to effectively predict and prevent the occurrence of engineering accidents. [0003] After extensive search, the prior art was found. The publication number is: CN109113107B, which discloses an intelligent monitoring system for building deep foundation pits. The system includes a sensing device and a deep foundation pit monitoring center set in the deep ...
