Inbound Overload Control System

Inbound Overload Control System

One-stop solution for overloading control—precise weighing, intelligent recognition, and efficient劝返 (劝返 means "persuading vehicles to turn back").

The entrance weigh-in-motion (WIM) system is an intelligent management platform that integrates dynamic weighing, vehicle outline detection, vehicle type recognition, and license plate capture into a single solution. The system strictly adheres to the new regulations issued by the Ministry of Transport for weight enforcement and can perform fully automated “health checks” on trucks entering toll stations.
The core weighing subsystem offers two axle-group scale configurations: 3.6 meters (standard lane) and 4.2 meters (extra-wide/curved lane). Combined with patented tensile sensor anti-fraud technology, this system ensures highly accurate and reliable weighing data. The system integrates laser 3D scanning and AI-powered visual recognition technologies to precisely detect whether vehicles exceed size or weight limits. It also links seamlessly with information boards to automatically guide overloaded vehicles back, effectively improving entryway traffic efficiency and ensuring the safety of roads and bridges.

Overview

Flexible weighing platform, compatible with all lanes.

Not only provides standard... 3.6m Axle-group scales are designed for straight lanes, and have been further optimized for common entry scenarios involving sharp turns and extra-wide lanes. 4.2m Extended-axis weighing system. Ensures that extra-long trailers and large-item transport vehicles can be smoothly placed on the scale, reducing measurement errors caused by vehicles shifting off the scale or pressing against the edges.

Unattended, intelligent persuasion to encourage return.

The system operates fully automatically, requiring no manual intervention. When an over-limit vehicle is detected, the system responds within milliseconds, simultaneously activating the LED information boards ahead to display red warning messages along with the vehicle’s license plate number and playing a voice prompt instructing the driver to turn around. At the same time, the data is uploaded to the toll collection system in real time, automatically blocking card issuance—truly achieving “replacing humans with machines.”

Multi-dimensional anti-cheating measures, sealing loopholes.

An integrated tensile force sensor prevents "dragging the scale," an infrared/laser light curtain prevents "jumping the scale," and a laser profilometer prevents "large vehicles using small-scale labels." By cross-validating data from multiple sensors, we have established a robust, closed-loop anti-fraud logic system that ensures the fairness of overloading enforcement efforts.

Guard the highway entrance and refuse to allow vehicles exceeding weight or size limits to enter.

This system is deployed at highway toll plaza entrances or on-ramps. Through a scientifically designed layout, it enables trucks to complete all necessary inspections before entering the toll lanes. Compliant vehicles can pass through quickly, while vehicles exceeding weight or dimension limits are automatically turned back. This not only safeguards road assets and rights but also eliminates, right from the source, the serious traffic safety risks posed by overloaded trucks.

Fully self-developed, deeply integrated

3.6m / 4.2m dual specifications—perfect for tackling even the “most challenging and complex issues”!

The entrance plaza has limited space and many curves, making it easy for large vehicles to drive off the edge of the weighing platform when turning. We offer widened and lengthened versions. 4.2m Axle group scales, perfectly suited for these special operating conditions.

Combined with the unique dual-bearing structure and 1000Hz Thanks to its high-frequency sampling technology, the system can capture complete axle-group waveforms whether the vehicle is traveling in a straight line or entering at an angle, ensuring that weighing accuracy consistently remains at the Level 1 standard set by national regulations.

Laser scanning leaves no room for oversized items to hide.

Being overweight is a hidden danger; being excessively long or wide is equally deadly. We’ve installed a simple gantry structure 1 meter in front of the weighbridge, equipped with three high-precision laser scanning sensors.

This system can construct a real-time 3D exterior model of vehicles and precisely measure their length, width, and height. The data is automatically linked to weight measurement results, enabling dual-level control over both “overweight” and “over-size” violations with no blind spots.

AI-assisted, eliminating “large vehicle with small label” practices.

How can we prevent 6-axis vehicles from masquerading as 4-axis vehicles? The system is equipped with an advanced laser-based axis-type identifier.

By scanning tire and chassis features, the system accurately identifies the number of axles and axle configurations (single or dual tires). Combined with license plate recognition data, the system automatically compares the vehicle’s registered information with the actual inspection data. Once any discrepancies are detected—such as a large vehicle with a small license plate or a fake axle—the system immediately triggers an alarm, assisting toll collectors in conducting inspections.

Industrial-grade design, all-weather protection

The overload control system is exposed year-round to harsh outdoor conditions. Our data acquisition processor employs... IP65 Thermostatic cabinet with protection rating.

Built-in three-level lightning protection, surge suppression, and watchdog reset circuitry ensure that the device remains operational and prevents data loss even under extreme weather conditions such as thunderstorms and high temperatures. For critical data, breakpoint resumption is supported—meaning that even if the network connection temporarily drops, the device will automatically resume uploading once the connection is restored, thereby guaranteeing data integrity.

Precise Dynamic Weighing and Overweight Vehicle Detection & Guidance for Return

With the deepening implementation of the “National Unified Network” operation and the policy of “mandatory inspection for trucks and prohibition of overloaded vehicles,” highway toll plazas at entry points are facing unprecedented traffic pressures. Traditional static weighing systems are inefficient and prone to severe congestion; meanwhile, outdated dynamic weighing systems often prove inadequate when confronted with new cheating tactics such as skipping weigh stations, speeding through weighbridges, or driving in S-shaped patterns. Moreover, these systems struggle to accurately capture vehicle dimensions—length, width, and height—leading to oversight and misjudgments of overloaded vehicles. This not only results in lost toll revenue but also poses serious safety risks to highways.
