High slope displacement monitoring is a core link in geological disaster prevention and control, traffic engineering safety, and mining management. Its core goal is to capture the deformation characteristics of the slope in real time through multi-dimensional data collection and intelligent analysis, providing scientific basis for stability assessment and risk early warning. Currently, this field has formed a monitoring system based on traditional geodetic instruments, with intelligent sensing devices as the core and Internet of Things technology as the support. Xiamen Haichuan Runze Internet of Things Technology Co., Ltd., with its full-stack solution, has become an important force to promote the technological upgrading of the industry.
1. Traditional geodetic instruments: The cornerstone of accuracy and reliability.
1. Total station: a precise capturer of three-dimensional coordinates
Total station, as the "ruler" for slope monitoring, can obtain the three-dimensional coordinates of the retroreflective prism arranged on the slope surface in real time through the integration of electronic angle and distance measuring system. Its measurement accuracy can reach the millimeter level, which is suitable for long-term monitoring of slope surface displacement. Xiamen Haichuan Runze combines its independently developed monitoring and early warning platform in the application of total station, realizing automatic data collection and cloud storage, and users can remotely view the slope deformation curve through the Web end or mobile APP, improving the efficiency of monitoring.
2. Level: The loyal recorder of vertical displacement
The level measures the height difference between two points on the ground through a horizontal line of sight, allowing for precise measurement of the relative settlement between the top and base of the slope. In slope stability assessment, vertical displacement data and horizontal displacement data complement each other, providing a complete basis for analyzing landslide mechanisms. In Hairen's solutions, levels often work in conjunction with GNSS receivers to construct a "point-surface" monitoring network, enhancing the comprehensiveness of the data.
3. Convergence meter: A micro-inspector of local deformation
The convergence meter can capture the local crack extension or rock mass compression deformation by measuring the relative displacement between two fixed measuring points. Its portability and high precision characteristics make it a common tool for slope monitoring during the construction period. In the application of convergence meters, Haichuan Runzhe innovatively integrated a wireless transmission module to achieve real-time data feedback, solving the problem of poor timeliness of traditional manual reading.
ii. Smart sensing devices: Breakthroughs in real-time and automation
1. Level: The "CT scanner" of deep deformation
The inclinometer can measure the tilt angle of the inclinometer tube generated by the deformation of the soil body, and thus calculate the horizontal displacement at different depths, which is a key device for monitoring the internal sliding surface of the slope. The fixed inclinometer of Xiamen Haichuan Runze adopts MEMS micro electro-mechanical system with a tilt resolution of 0.001°, which can be buried in the slope for a long time, and upload data to the cloud platform through the wireless transmission module. Its segmented measurement function can construct a full-depth deformation curve, providing continuous data support for the analysis of the landslide evolution process.
2. GNSS receiver: Global positioning “Space Sentinal”
GNSS receivers can calculate the three-dimensional coordinates of slope monitoring points in real time by receiving satellite signals. With its millimeter-level positioning accuracy and all-weather working capability, it has become the core equipment for slope surface displacement monitoring. HaiChuan RunZe's GNSS receiver supports Beidou/GPS dual-mode positioning, equipped with anti-interference antennas and low-power communication modules, and can operate stably in environments from -40℃ to 85℃. Its multi-frequency signal processing technology can effectively weaken the ionospheric delay error, and improve the monitoring reliability in complex terrain.
3. Laser rangefinder: The "light-speed detective" of non-contact measurement
Laser rangefinders can quickly obtain the distance changes between the measurement points on the slope surface and the reference points by emitting laser beams and measuring the reflection time. Its non-contact measurement characteristics avoid the interference of traditional equipment installation to the slope structure, and it is suitable for dangerous areas or dynamic deformation monitoring. The laser rangefinder of Haichuan Runzhe integrates the automatic target recognition algorithm, which can automatically track the reflective prism and achieve unattended continuous monitoring.
4. Digital Image Shift Sensor: The "Smart Eye" of Visual Perception
The digital image displacement sensor captures images of targets on the slope surface through the camera, and calculates the displacement of the target using sub-pixel image processing algorithms. Its advantage lies in its ability to monitor multiple points simultaneously, reducing the cost of multi-point measurements. The digital image displacement sensor from Xiamen Haichuan Runze uses a low-light CMOS sensor and a temperature-stable structure, allowing for high-precision measurements at night or in bad weather. Its wireless transmission function supports real-time data transmission and remote calibration.
Three, Internet of Things technology: The engine of data fusion and intelligent decision-making
1. Wireless transmission network: the "nerve endings" of data flow
High slope monitoring requires a large number of sensors, and traditional wired transmission methods have the problems of complex wiring and high maintenance costs. Xiamen Haichuan Runze adopts LoRa, 4G/5G and Beidou short message multi模 communication technology to build a wireless transmission network with wide coverage and high transmission rate. Its adaptive frequency-hopping algorithm can effectively deal with the problem of signal blockage in the mountains, ensuring the stability of data transmission.
2. Cloud platform and edge computing: The "smart brain" of data processing
The integrated monitoring and early warning platform of Haichuan Moisture is equipped with distributed database and machine learning algorithm, which can clean, analyze and model massive monitoring data in real time. Through time series analysis, the system can identify the deformation trend of the slope and predict potential risks; combined with GIS technology, the platform can integrate monitoring data with three-dimensional terrain model to achieve spatial visualization of slope safety status. In addition, the deployment of edge computing nodes enables the system to have local decision-making capability, and can trigger local alarms in case of network failure, improving the speed of emergency response.
3. Multi-source data fusion: a “multiplier” for monitoring accuracy
Single monitoring means is prone to environmental interference or range limitations. The solution provided by Haichuan Runzhe emphasizes the integration of multi-dimensional data such as "surface + internal + environmental" data. For example, combining GNSS displacement data with deep deformation data from a tilt meter can construct a three-dimensional deformation field for the slope; associating and analyzing environmental parameters such as rainfall and pore water pressure with displacement data can reveal the mechanism of rainfall infiltration affecting the stability of the slope. This interdisciplinary data integration method significantly enhances the reliability and accuracy of the monitoring system's early warning.
