Product Introduction

Integrated Crack Monitor

SDLF-G01

The Integrated Crack Monitor is an intelligent monitoring terminal that leverages cable‑pull displacement sensing and multi‑parameter fusion technology, specifically designed for monitoring surface deformations such as slope cracks and retaining wall fissures. The device incorporates a high‑precision displacement sensor and a triaxial accelerometer/tilt sensor, enabling real-time monitoring of crack width changes, wall vibrations, and tilt angles, while supporting remote data transmission and alarm notifications via LoRa or 4G networks. With a robust structure and straightforward installation, it is well suited for long‑term automated monitoring in harsh outdoor environments.

PRODUCT FEATURES

  • Real-time automatic monitoring: By employing a timed‑sampling and trigger‑based reporting mode, continuous, automated, low‑power monitoring of structural crack conditions is achieved.
  • Three-parameter synchronous acquisition: It can simultaneously monitor crack opening and closing, vibration acceleration, and changes in tilt angle, providing a comprehensive assessment of the structure’s safety condition.
  • Intelligent Filtering for Stable Data: By applying Kalman filtering, environmental interference is effectively suppressed, ensuring the accuracy and reliability of the collected data.
  • Multi-mode communication compatibility: Supports multiple communication modes, including 4G and LoRa self-organizing networks, to meet the deployment requirements of various scenarios.
  • Remote Operations and Maintenance Management: Supports remote configuration of device parameters, over-the-air firmware updates, and real-time monitoring of device operating status.

APPLICATION FIELD

This solution targets potential geological hazard sites along railway corridors—such as slope faces, tunnel portals, and embankments—by deploying smart sensors including inclinometers, crack meters, GNSS devices, and rain gauges to establish an automated monitoring and early‑warning system. It collects real-time data on deformation, rainfall, and other parameters, transmitting it via multi‑link communication to a cloud platform, where intelligent algorithms perform analysis and issue tiered alerts. The system has been successfully implemented in projects such as the Xiang–Gui Line, the Nanning Railway Bureau’s flood‑control network, and the Huangbai Railway, significantly enhancing the railway sector’s capacity for preventing and mitigating geological hazards.

Geological Hazard Monitoring and Early Warning Solution for Railway Corridors

The smart port monitoring solution covers multiple aspects, including port equipment, cargo handling processes, yard safety, personnel operating procedures, environmental changes, port operational efficiency, and energy consumption. By collecting and analyzing data in real time, the system can promptly identify and address issues, thereby ensuring stable, safe, and efficient port operations. At the same time, monitoring and optimizing energy consumption helps ports reduce energy use and improve energy efficiency.

Smart Port Solution

The highway slope monitoring and early-warning system is an integrated management platform that combines remote data acquisition, wireless data transmission, data analysis and processing, and disaster early warning and forecasting. By deploying automated terminal monitoring devices, the system conducts real-time monitoring of slope displacement and deformation, stress levels, changes in environmental factors, and groundwater activity, while also establishing safety assessment criteria for highway slopes. The system utilizes 4G, NB-IoT, and LoRa wireless networks to acquire monitoring data in real time. The backend data management platform then performs intelligent analysis and disaster prediction based on these criteria. When monitored data exceed preset warning thresholds, the system automatically triggers an alarm and notifies relevant personnel via the management system’s messaging interface, mobile app, or SMS. With 24-hour, all-round, dynamic monitoring, users can stay informed about highway slope safety at any time and from any location, thereby advancing from manual and automated monitoring to intelligent monitoring. This provides a scientific basis for highway slope disaster prevention and control, reinforcement engineering design, and the timely elimination of safety hazards.

Automated Safety Monitoring and Early Warning Solution for Highway Slopes

This solution is designed for scenarios such as tailings ponds, heap leaching sites, and industrial waste‑slag storage facilities in both metallic and non‑metallic mines. It deploys intelligent monitoring devices—including GNSS, piezometers, water level gauges, rain gauges, flume flow meters, inclinometers, crack meters, and video surveillance—to establish an online safety monitoring and early‑warning system for tailings facilities. By continuously collecting real‑time data on dam displacement, the phreatic line, pond water levels, seepage rates, rainfall amounts, and on‑site imagery, the system transmits this information via 4G, Beidou, or LoRa to a cloud‑based platform. Advanced stability analysis models then perform intelligent data interpretation and tiered warning assessments. When threshold values are exceeded, the system automatically issues alerts and activates on‑site alarm devices, providing round‑the‑clock, comprehensive technical support for safe tailings‑pond operations, flood‑control and emergency management, thereby effectively mitigating the risk of dam failures.
