[0002] With the increasing development of my country's infrastructure and the increasing size of buildings, resources are becoming increasingly tight. Construction often occurs near important buildings or high-rise buildings are built in compact environments, such as new stations near residential areas, buildings near dams, etc.; due to the additional huge pressure on the foundation, the base will inevitably deform, causing uneven settlement of the foundations of surrounding buildings, cracks and collapse of buildings, and even huge losses to people's lives and property.

[0003] In order to ensure the smooth progress of the project and the safety of important buildings around it, it is necessary to collect and accumulate relevant data. Foundation settlement monitoring is an indispensable key link and can be widely used in the construction of water conservancy dams, mountain tunnels, hillsides, high-rise buildings and other projects.

[0041] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of this application.

[0042] Example 1:

[0043] The present invention provides a real-time monitoring system for foundation pit displacement of smart construction sites based on the Internet. Figure 1-4 , an Internet-based smart construction site foundation pit displacement real-time monitoring system, comprising a processor, a plurality of monitoring devices 1 installed in the foundation pit and a plurality of offset calibration devices 2 installed on the foundation support;

[0044] The processor is connected to a data processing module, an image processing module, an image recognition module, a data storage module, an Internet module, and an alarm. The alarm is used to alert relevant safety officers or technicians on the construction site. The Internet module is used to connect the system to the Internet. The image processing module is used to sharpen the image captured by the recording device 102. The image recognition module is used for image analysis.

[0045] See also Figure 1 and Figure 5The monitoring device 1 includes a support frame 101, on which a recording device 102, a light beam generator 103, and a radiation sensor 104 are mounted. The lens of the recording device 102, the light beam generator 103, and the radiation sensor 104 are located on the same horizontal mounting surface. The recording device 102, the light beam generator 103, and the radiation sensor 104 constitute the monitoring end of the monitoring device 1.

[0046] The recording device 102 is used to capture images at the offset calibration device 2, such as long-term video recording or high-definition image capture at the offset calibration device 2. The light beam generator 103 is used to emit visible light beams. A controller is installed in the monitoring device 1, and multiple monitoring devices 1 are connected to the processor via the controller. The laser wavelengths of the radiation sensor include 905nm and 1550nm, and the wavelength of the light beam generator is 400-700nm.

[0047] The monitoring device 1 is equipped with a wireless signal transmission module, and the processor is connected to a wireless signal communication module, allowing the monitoring device 1 to transmit data via wireless signals. The support frame 101 includes a lifting bracket and a rotating platform that matches the video recording device 102. A stepper motor that matches the rotating platform is installed on the support frame 101, and a skilled person in the art will select an appropriate stepper motor model for installation. Both the light beam generator 103 and the radiation sensor 104 are mounted on the video recording device 102. The rotating platform can drive the video recording device 102 to rotate to any angle, facilitating the matching of the video recording device 102 with any other offset calibration device 2 on the same horizontal plane. The monitoring device 1 is electrically connected to an external power supply.

[0048] The fixed position of the monitoring end of each monitoring device 1 is at a different horizontal plane, and the installation position of the monitoring device 1 is close to the foundation support; the foundation support is divided into multiple offset monitoring areas, and multiple offset calibration devices 2 are evenly distributed in the multiple offset monitoring areas, and the multiple offset calibration devices 2 in the offset monitoring area are staggered on different horizontal installation surfaces; by comparing the offset monitoring data of different horizontal positions in the same monitoring area with multiple monitoring devices 1, it is convenient to calibrate the error of the offset monitoring data.

[0049] See also Figure 6-7 The offset calibration device 2 includes a fixed frame 201, a laser receiver 202 is installed in the fixed frame 201, and a reflective ring 203 is fixedly connected to the outside of the fixed frame 201; the reflective ring 203 is supported by a high-temperature resistant material to prevent the reflective ring 203 from being heated by the radiation beam and damaged; when the radiation beam emitted by the beam generator 103 irradiates the reflective ring 203, the recording device 102 captures a highlight area on the image;

[0050] The processor determines the offset based on the brightness of the highlighted area identified by the image processor. In this solution, when the ray beam directly hits the reflective ring 203, the brightness of the highlighted area in the image captured by the recording device 102 is used as the judgment standard. During the normal monitoring process of the monitoring device 1, when the brightness of the highlighted area in the image captured by the recording device 102 reaches the above judgment standard, the processor issues a foundation offset alarm.

[0051] The recording device 102 is equipped with a magnifying lens with a front sight and a UV filter, which protects the recording device 102 by the UV filter and reduces the damage of the lens to the lens by external rays; the fixed frame 201 is equipped with a lens with a calibration front sight, which ensures that the recording device 102 performs high-definition shooting of the offset calibration device 2 through the magnifying lens, and performs a rough judgment of the foundation offset by identifying whether the lens front sight and the lens front sight in the captured image match. The image recognition module recognizes the image collected by the recording device 102, and performs a preliminary judgment of the foundation offset rate by determining the overlap rate and overlap area of ​​the lens front sight and the lens front sight in the image. A technician in this field sets an image front sight overlap rate calculation program in the processor based on machine vision technology. When the image front sight overlap rate exceeds the preset value of the technician, the processor can activate the alarm to sound an alarm;

[0052] See also Figure 2-3 , the workflow of the monitoring system is:

[0053] A, routine monitoring;

[0054] A1, the monitoring device 1 performs routine monitoring within the set time T1, and during routine monitoring, the offset calibration device 2 is photographed by the recording device 102;

[0055] A2: The captured image is uploaded to the processor, which uses image processing and image recognition to determine whether the crosshairs have shifted. If it is determined that the crosshairs have not shifted, the monitoring device 1 turns on the radiation sensor 104 for accurate detection after the set time T1 expires.

[0056] A3, if the crosshairs in the monitoring image are offset, the beam generators 103 of the multiple monitoring devices are turned on, and if a highlight area is found in the collected image, the alarm is sounded;

[0057] If the image is normal, the calibration device is turned off, and then the radiation sensor 104 is turned on for accurate detection;

[0058] B, accurate detection;

[0059] B1. During precise detection, the offset is measured by the combined action of the radiation sensor 104 and the laser receiver 202. Offset measurement using the radiation sensor 104 and the laser receiver 202 is conventional technology. The radiation sensor 104 generates a reference plane by rotating the laser beam. This reference plane is detected by the laser receiver 202. If the receiver moves above or below the reference plane, the resulting deviation is detected. This allows the deviation value to be measured when the radiation sensor 104 or the laser receiver 202 sends an upward or downward offset relative to the initial position.

[0060] B2, if the offset exceeds the set value, the offset monitoring data is uploaded and an alarm is issued; if the offset does not exceed the set value, the monitoring device 1 is turned off and normal monitoring work is performed after waiting for the set time T2.

[0061] This solution enables timely detection of foundation offset during long-term monitoring. Rough calibration is performed through image recognition during routine monitoring, and precise offset detection is used regularly for offset monitoring, ensuring comprehensive, long-term, and stable monitoring of foundation support.

[0062] Example 2:

[0063] The present invention provides a real-time monitoring system for foundation pit displacement of smart construction sites based on the Internet. Figure 4 and Figure 8 , wherein the components identical or corresponding to those in Example 1 are designated by the corresponding reference numerals in Example 1. For the sake of simplicity, only the differences from Example 1 are described below. The differences between Example 2 and Example 1 are:

[0064] The monitoring ends of each monitoring device 1 are respectively installed at different horizontal planes, and the monitoring ends of each monitoring device 1 are respectively matched with multiple offset calibration devices 2. The recording device 102 on the monitoring device 1 can be rotated to respectively match with the multiple offset calibration devices 2, and when matched, the monitoring ends of the recording device 102 are facing the offset calibration devices 2;

[0065] When performing the shooting and precise detection steps in steps A1 and B1: the recording device 102 is driven to rotate so that its monitoring end is matched with multiple offset calibration devices 2 respectively. After the recording device 102 completes shooting or precise detection after matching with an offset calibration device 2, the rotating platform drives the recording device 102 to rotate a preset angle so that the recording device 102 is matched with another offset calibration device 2 on the same plane. The monitoring end of the recording device 102 cooperates with multiple offset calibration devices 2 on the same horizontal plane to realize multi-area offset monitoring of the facade of the foundation by one recording device 102.

[0066] The above is only the best implementation method adopted by this application in combination with current actual needs, but the scope of protection of this application is not limited to this.
