Project Introduction

The road vehicle overheating early‑warning system is an intelligent traffic‑safety solution that integrates license‑plate recognition, infrared thermal imaging for temperature measurement, backend data analysis, overheating alerts, and synchronized audio‑visual notifications. Designed for continuous vehicle flow on highways, the system enables non‑contact temperature monitoring and rapid identification of passing vehicles, providing real‑time warnings, data logging, and coordinated response for vehicles at risk of abnormal temperature rise. This helps management authorities enhance road safety prevention and control, reducing the risks of vehicle spontaneous combustion, mechanical overheating, and sudden accidents.

 

I. Value of the Plan

1.1 Why is a road vehicle over-temperature warning system needed?

On key road segments such as highways, toll stations, service areas, and bridges and tunnels, factors like prolonged vehicle operation, heavy‑load traffic, fluctuating ambient temperatures, brake or tire malfunctions, and thermal runaway in the engine compartment can all trigger localized overheating and even vehicle fires. If these issues are not detected in advance, they can easily lead to traffic congestion, accidents, fire hazards, and secondary safety incidents.

Traditional manual inspection methods suffer from issues such as delayed detection, limited coverage, and insufficient continuity. In contrast, the road vehicle overheating early‑warning system leverages real-time front‑end sensing and intelligent back‑end analysis to continuously monitor vehicle temperatures, providing timely warnings before risks escalate and helping road management authorities establish a more efficient, proactive prevention and control mechanism.

1.2 Core Value of the Plan

• Non-contact rapid screening : Identification and temperature measurement can be completed while vehicles are in motion, eliminating the need to stop for inspection.
• Rapid detection of abnormal vehicles : Provide timely warnings for targets exhibiting abnormal temperature rises in areas such as the engine compartment, tires, and brake-related components.
• License plate and temperature information are synchronously linked. : Establish a record linking the target vehicle’s identity with its thermal information, facilitating subsequent tracking and response.
• Strong interoperability It can interface with audio‑visual alarms, information display boards, platform alarm interfaces, and more, enabling synchronized response between the现场 (on-site) and the backend.
• Suitable for continuous operation scenarios : Meets the requirements for long-term, stable deployment in scenarios such as highway toll plazas, service area entrances, and key checkpoint locations.

III. System Workflow

3.1 Process Description

When a vehicle passes through the monitored area, the system automatically executes the following sequence:

① Vehicle enters the monitoring area

Front-end devices capture target vehicles in real time, acquiring both full‑vehicle traffic images and thermal imaging data.

② License Plate Recognition

The system automatically recognizes vehicle license plate information and supports the identification of various types of plates, including standard plates and new-energy vehicle plates.

③ Temperature Acquisition and Heatmap Generation

The infrared thermal imaging unit simultaneously performs temperature measurements on critical vehicle areas, generating a temperature distribution map and providing temperature readings.

④ Data Correlation and Backend Analytics

The system integrates license plate data, temperature readings, heat map information, and time‑and‑location metadata into a unified dataset, which is then uploaded to the backend platform for intelligent analysis.

⑤ Anomaly Detection and Early Warning Triggering

When the temperature in a specific vehicle area exceeds the set threshold or an obvious abnormal thermal distribution is detected, the system automatically triggers an over-temperature warning.

⑥ On-site coordination and backend logging

Based on project requirements, the system can integrate with audio‑visual alarms, information display boards, and platform alert windows, while also archiving incidents to facilitate subsequent tracking and statistical analysis.

Module Description:
This is the core closed-loop of the entire system, spanning from “vehicle detection” to “license‑plate recognition,” from “thermal‑imaging temperature measurement” to “anomaly assessment,” and further to “alarm linkage” and “event logging,” thereby enabling end-to-end management of road‑vehicle overheating risks.
