Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit monitoring, in particular to a full-automatic foundation pit deep horizontal displacement monitoring system. Background Art

[0002] In construction projects, foundation pit construction is a complex and risky engineering link. During the excavation and support of the foundation pit, the deformation and displacement of the soil is an important monitoring indicator, especially the deep horizontal displacement. The monitoring of deep horizontal displacement is of great significance for evaluating the stability of the foundation pit support structure, the safety of underground pipelines and the impact on surrounding buildings.

[0003] The traditional method of monitoring deep horizontal displacement of foundation pits is usually manual measurement and recording. Engineering personnel manually measure or install traditional monitoring equipment (such as inclinometers, displacement meters, strain gauges, etc.), and then regularly collect and analyze data. Manual monitoring requires a lot of human resources and time costs, and is easily interfered by the external environment and human factors. The timeliness and accuracy of the monitoring data cannot be guaranteed. In addition, the traditional monitoring method cannot achieve real-time monitoring and automatic alarm. Once an abnormal situation occurs, engineering personnel are often unable to discover and take countermeasures in time, which can easily lead to safety accidents. Therefore, a fully automatic deep horizontal displacement monitoring system for foundation pits is proposed to solve the above problems. Utility Model Content

[0039] The smart terminal 7 is used to display the real-time data and monitoring trend of the deep horizontal displacement of the soil, and provide the functions of data perception, control analysis, early warning and automatic generation of monitoring reports.

[0040] Among them, the model of the monitoring sensor 2 is the RT-1010 array displacement meter 9, which is placed in the inclinometer tube 8. The outer side of the RT-1010 array displacement meter 9 is provided with a first section directional wheel 11 and a tail section guide wheel 12, and a lower pressure cover 10 is fixedly installed on the top of the inclinometer tube 8.

[0041] The monitoring sensor 2 adopts the RT-1010 array displacement meter 9, which is pressed down and installed in the side inclined pipe 8 and fixed with the lower pressure cover 10. The RT-1010 array displacement meter 9 is used to accurately measure and record the changes in the deep horizontal displacement of the foundation pit, and transmit the data to the data acquisition and preprocessing module 3.

[0042] Among them, the data acquisition unit 31 includes an analog-to-digital converter 311, an FPGA acquisition module 312 and a data acquisition unit ARM processor 313. After the data of the monitoring sensor 2 is converted into a digital signal by the analog-to-digital converter 311, it is transmitted to the FPGA acquisition module 312 for data analysis and written into the FI FO memory in the FPGA acquisition module 312. The data acquisition unit ARM processor 313 reads the deep horizontal displacement data cached in the FI FO memory in the FPGA acquisition module 312, and then transmits it to the data preprocessing unit 32 for processing.

[0046] The solar power supply module 1 includes a solar panel and a related battery or energy storage device. The solar panel converts solar energy into electrical energy and stores it in the battery or energy storage device to provide the power required for system operation.

[0047] The solar power supply module 1 is connected to the data acquisition and preprocessing module 3.

During the entire process of foundation pit construction, the intelligent terminal displays the deep horizontal displacement data of soil in real time in the form of graphs and tables through the mobile phone APP and computer web interface, analyzes monitoring trends, and identifies abnormal data. At the same time, the system pre-sets three-level red, yellow and green warning values. When the monitoring data exceeds the limit, it automatically sends a text message to the on-site staff. At the same time, it provides data perception and automatic generation of monitoring reports, providing users with comprehensive and convenient foundation pit deep horizontal displacement monitoring and management services.

[0050] Working principle:

[0051] During installation, firstly, the RT-1010 array displacement meter 9 and the first section directional guide wheel 11 are synchronously lowered into the inclinometer tube 8 until the first section directional guide wheel 11 is completely lowered and touches the bottom. During this process, the current X-MARK line direction of the RT-1010 array displacement meter 9 is recorded, and the upper direction is fixed with the tail section directional wheel 12. After the installation is completed, fix the lower pressure cover 10 and connect it to the data acquisition and preprocessing module 3, connect the solar power supply module 1 to the data acquisition and preprocessing module 3, connect the data acquisition and preprocessing module 3 to the sound and light alarm 4, then place the sound and light alarm 4 in a place that is easy to observe, place the data acquisition and processor 4 in a protective box together with the solar power supply module 1, and place it in the designated position. Finally, wait for the indicator light of the data acquisition and processor 4 to be in normal state, log in to the cloud platform to mount the RT-1010 array displacement meter 9 device, and after completion, real-time online monitoring data can be collected;

[0052] When in use, the monitoring data is transmitted to the cloud processor 6 through the communication module 5 for analysis, storage and display on the intelligent terminal 7. The cloud processor 6 calculates the physical quantity of the collected data according to the principle formula, and displays the collected data in order according to the measuring point and time. The collected data is timely drawn into a data graph for easy observation. The user can log in through a computer or mobile phone to view the graph and original data in real time. When the calculated physical quantity exceeds the set alarm value, the system will use a variety of alarm methods (such as text messages, etc.) to prompt the observer. In addition, users can also customize reports for various periods such as years, seasons, months, weeks, and days to facilitate regular analysis and management of monitoring data. The system resources are complex and numerous, and the information and monitoring data that constitute it can be easily backed up and restored, which not only ensures the reliability and security of the system, but also makes the establishment, maintenance and expansion of the system more convenient.
