Municipal Road Height-Restriction Barrier Collision Monitoring and Alarm Solution
Background Introduction
As highway and urban road networks continue to expand, the number of underpass bridges and culverts is steadily increasing. To ensure the safety of the bridge structures above, mandatory height‑restriction barriers are commonly installed on the roads below. However, in actual operation, accidents involving collisions with these barriers—caused by driver inattention, unclear road signage, or vehicles exceeding the height limit—occur frequently, giving rise to a series of serious problems:
First, it directly endangers the driver’s safety and can easily lead to traffic disruptions.
Second, severe collisions may damage critical infrastructure such as bridges and culverts, creating significant safety hazards.
Third, following the accident, the lack of timely and reliable evidence has made it difficult for regulatory authorities to trace the incident, thereby hindering the attribution of liability and the settlement of claims.
Accordingly, developing an intelligent, traceable collision‑monitoring and alarm system that enables end-to-end management—from proactive early warning to post‑incident evidence collection—has become an urgent necessity for ensuring operational safety in municipal road networks and at highway–railway interchanges.
Solution Overview
This solution is a system that integrates Ultra-high-speed warning, collision monitoring, video-based evidence collection, and intelligent analysis An integrated municipal road height‑restriction protective frame safety system.
The system aims to leverage technological solutions to transform passive protection into an intelligent regulatory model characterized by proactive early warning and precision management.
The solution integrates multiple intelligent sensing and monitoring modules into the height‑restriction barrier, enabling real-time detection of vehicle overheight conditions and collision events.
The system can not only operate when a vehicle approaches Audio-visual warning , effectively preventing collisions; and even more so at the moment of impact Automatically trigger an alarm , synchronize Complete event video recording, license plate recognition, and data upload. 。
This solution establishes a comprehensive management closed-loop encompassing “pre‑event early warning, in‑process alerts, and post‑event root‑cause analysis,” providing robust technical support for operational safety, law enforcement evidence collection, and accident liability determination across municipal, highway, and railway authorities.
FEATURES OF THE SOLUTION

Wireless Networking and Ultra-Long Early Warning Range
System Architecture
The system employs a mature and robust three-tier IoT architecture, characterized by clear layering and reliable operation:
Perception Layer
It comprises an integrated array of smart sensing devices—such as inclinometers, crack meters, static leveling instruments, and vibration sensors—deployed on the building’s load-bearing walls, beams, columns, foundations, and adjacent retaining walls, responsible for acquiring real-time raw data on structural deformation, settlement, and vibration.
Network layer
By leveraging public or private wireless communication networks such as 4G, NB‑IoT, and LoRa, a low‑power, highly reliable uplink channel is established to securely and reliably transmit data from the perception layer to the cloud server.
Data Application Layer
The cloud-based monitoring and early-warning platform is responsible for data reception, storage, analysis, visualization, and the issuance of alerts. The platform offers real-time monitoring, historical data retrieval, trend analysis, alert‑rule configuration, device management, and system administration, while providing administrators with a user-friendly interface via both a web portal and a mobile app.
System platform
By deploying automated intelligent monitoring terminals, key structural data—including building tilt, crack patterns, and settlement—are collected in real time from the structure and its associated retaining walls.
The backend data management platform performs intelligent analysis of multi-source monitoring data, assesses trends, and predicts potential disasters, while automatically pushing tiered early-warning notifications to relevant personnel.
System Implementation 7×24 Hourly, round-the-clock, all‑round dynamic monitoring enables users to track the deformation and structural health of buildings anytime, anywhere, providing a scientific basis for early warning, preventive measures, and maintenance management of residential buildings and retaining walls.
