Safety Monitoring and Early Warning Solution for Slope-Excavation Housing Construction

Background Introduction

By implementing automated monitoring of landslide hazard zones caused by slope-cutting for residential construction, the system continuously collects deformation data from the slope and leverages big data and cloud computing technologies to conduct risk analysis. Prior to a disaster occurring, it sends early warning notifications to residents downstream, enabling timely evacuations and thereby preventing loss of life and property. This safety-monitoring system for slope-cutting-based housing, centered on IoT technology, boasts reliable operation, streamlined functionality, appropriate measurement accuracy, high cost-effectiveness, rapid installation, easy maintenance, and intelligent early-warning capabilities. Moreover, through real-time monitoring, automated analysis, and prompt alerts at hazard locations, it minimizes disaster-related losses to the greatest extent possible.

Solution Overview

The slope-adjacent residential safety monitoring system comprises slope probes, maintenance-free piezoelectric rain gauges, early-warning public-address systems, and in-home alarm devices, all of which support dual-channel communication via LoRa and 4G. Leveraging LoRa self-organizing network technology, a mesh network is established between the slope and at-risk residences, enabling autonomous data collection, real-time monitoring, and automatic early warning. Once a monitoring station detects data exceeding the alert threshold, the cloud platform transmits an alert message and, through the mesh network, sends notification alerts to the public-address system and in-home alarms. Simultaneously, all devices connect to the cloud platform via the 4G public network to report deformation data in real time; the cloud platform then applies analytical models to assess risks and issue warnings. When deformation surpasses the preset threshold, the system automatically pushes alert notifications to users; in cases of severe deformation, the cloud platform can also initiate voice calls to the responsible party for hazard mitigation.

FEATURES OF THE SOLUTION

Multiple communication links

Multiple communication links

All monitoring and early-warning devices support 3G/4G/5G multi-network compatibility, as well as public-network communications such as NB-IoT and BeiDou, and local LoRa ad-hoc networking, thereby establishing a redundant monitoring and early-warning transmission network.
Multiple alert modes

Multiple alert modes

The system supports three alert modes—automatic alerts, platform-based alerts, and manual alerts—ensuring precise, individualized notifications delivered directly to households.
One station, one code; real-time information access.

QR codes are provided for all equipment and can be posted on the equipment itself and on notice boards. Residents can scan the codes to view basic information about potential hazard locations and to monitor deformation status.

 

Application Scenario Configuration

Starting from the uppermost stress concentration point on the high slope and proceeding downward, comprehensive monitoring is conducted across the upper, middle, and lower structural layers of the slope, with a focus on individual measurement points and extending to area-wide coverage, thereby achieving all-round, dynamic micro-deformation monitoring of the entire slope mass.

Display of the Slope-Excavation Housing Safety Monitoring and Early Warning Platform

By deploying automated terminal monitoring devices, the system acquires real-time data on monitored targets. The backend data management platform then performs intelligent analysis and hazard prediction on the collected data, automatically issuing disaster warning and forecast information to relevant personnel. This enables 24-hour dynamic, all-round monitoring, allowing for continuous tracking—anytime, anywhere—of railway slope deformation, displacement, rockfalls and debris flows, as well as changes in environmental factors and structural safety conditions. Such capabilities provide a scientific basis for natural slope hazard prevention and control, reinforcement engineering design, and the timely elimination of safety hazards.
