Automated Safety Monitoring and Early Warning Solution for Highway Slopes

Background Introduction

Highway slopes differ from those in water conservancy, mining, land and resources, urban construction, and even railway projects in terms of site conditions, geological environments, and management practices, and thus possess their own unique characteristics.

Solution Overview

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 evaluation criteria for highway slopes. The system utilizes 4G, NB-IoT, and LoRa wireless networks to transmit monitoring data in real time. The backend data management platform then performs intelligent analysis and disaster prediction based on these criteria. When monitored data exceeds 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.

FEATURES OF THE SOLUTION

Distributed Deployment

Distributed Deployment

Wireless networking technology enables intelligent data acquisition terminals to centrally collect data from various monitoring stations within a 1 km radius via wireless transmission, making it suitable for a wide range of complex geological hazard environments.
Multiple communication links

Multiple communication links

All monitoring and early-warning devices support public-network communications such as 2G/3G/4G and NB-IoT, as well as local LoRa self-organizing network communication, thereby establishing a redundant monitoring and early-warning transmission network.
Multiple alert modes

Multiple alert modes

The system supports three alert modes: automated alerts, platform-based alerts, and manual alerts.

 

System Solution

The construction of an automated safety monitoring and early-warning system for highway slopes is primarily divided into five components: deformation monitoring, stress monitoring, groundwater monitoring, rainfall monitoring, and on-site video monitoring.

Platform Display

The highway health monitoring and early-warning platform comprises several functional modules, including user management, basic highway information management, highway information management, monitoring-station management, query and management, data analysis, and forecasting and early-warning. Through this platform, users can promptly obtain real-time monitoring data on slope surface displacement, settlement, rainfall, internal displacement, and crack development, thereby enabling timely management decision-making.

Geodetic GNSS receiver

The geodetic GNSS receiver is a versatile deformation-monitoring device that integrates a high‑precision GNSS module with MEMS sensors. It supports multi‑system, multi‑frequency signal reception, including BeiDou‑3, GPS, and GLONASS, and delivers millimeter‑level static monitoring as well as centimeter‑level dynamic monitoring.
