Smart vehicle weighing  

NLT Group’s Smart Vehicle Weighing 4.0 solution helps minimize overloaded vehicles on the road. With a fully automated weighing and vehicle monitoring system, road infrastructure is optimally protected with extremely cost-effective and efficient investment, without affecting traffic flow.

The system operates with vehicle position sensors, barriers, card readers, etc., combined with surveillance cameras to create a transparent vehicle weighing system that prevents fraud and runs fully automatically. With remote monitoring and control capabilities, image reports captured by cameras and the data linked with accounting software, business management, and parking management systems enable a closed-loop management system that is optimized for enterprises.

Key features of NLT Group’s smart vehicle weighing system

NLT Group’s smart vehicle weighing system will provide 24/24 monitoring of vehicles travelling across the city, with a focus on heavy trucks, container trucks, construction material carriers, mineral transport vehicles, etc., which pose risks to transport infrastructure and road traffic safety. The product integrates smart features that deliver outstanding effectiveness in traffic management, including:

• Easy and fast installation on key transport corridors
• Addresses all current limitations (manual control and enforcement) of portable scales and mobile weighing vehicles
• Accurate, simple, and fast vehicle weighing in all weather conditions with the most cost-effective operating expenses
• Integrates a dedicated AI license plate recognition camera system developed by NLT Group with high accuracy and fast recognition time, providing 24/24 monitoring of vehicles travelling across the city
• Enables easy monitoring and automated enforcement with image evidence and overload data stored in the system database
• Optimizes all workflows and procedures for cargo weighing
• Allows centralized management of weighing stations on the Mobile App/ Website
• Retrieves all types of station reports and detailed information for each weighing session

Outstanding advantages of the smart vehicle weighing system

High accuracy

Under ideal conditions (laboratory conditions), the sensor system delivers an error rate of under 2%. This result confirms that quartz sensors are fully suitable for high-accuracy WIM measurements and can be used for applications such as enforcement and overweight toll collection.

Stability

The system uses highly stable quartz sensors. The measurement performance of quartz sensors remains very stable throughout the lifecycle of the WIM system, meaning frequent calibration or maintenance is not required. This is important and valuable in reducing maintenance costs and minimizing traffic disruption if the weighing system needs servicing.

Not temperature-dependent

Quartz WIM sensors are not temperature-dependent (error is only 0.05%/10C). This is very important to the performance of the entire WIM system, especially for countries with seasonal climate and environmental changes like Vietnam.

Customizable to road settlement

Quartz WIM sensors are installed on the road surface, which must be free of unevenness or speed bumps. Milling and paving an asphalt layer over the top surface of the sensor allows the WIM sensor to be installed with an allowable road settlement of 0÷10mm.

Easy installation

Based on the experience of NLT’s WIM weigh-in-motion engineers and experts, installing road-embedded sensors will not significantly affect traffic flow on the route.

No impact on the road surface

At the installation location, if the road surface meets the standard thickness of over 60mm, sensor installation will not affect road surface quality.

Automatic overload alerts

Overloaded vehicle information is immediately displayed on the system software’s operating screen.

Independent control

Integrated control with toll collection

Patrol units and competent authorities (Department Inspectorate, Traffic Police) can use the weighing system software anywhere as long as they are connected to the central server to receive overload alerts.

Hardware:

• Load sensors: determine axle loads, gross vehicle weight, as well as other related information of vehicles passing through the station.
• Inductive loops: detect vehicles passing through the station.
• Control cabinet: Collect all relevant information about vehicles passing through the weighing station from load sensors, inductive loops and cameras. Calculate and determine whether a vehicle is overloaded and output the information to the warning display. Transfer all information to the Server for storage.
• Server: stores the weighing station’s data.
• Control station: located about 300–500 meters away from the weighing station, accesses data of vehicles passing through the station via the Internet or 3G. If an overloaded vehicle is detected, the competent authorities will be notified for appropriate handling.
• Control center: Store, manage and monitor information from all weighing stations remotely.

Software:

• Simple interface, easy to monitor and operate
• 24/7 remote monitoring of weighing stations
• Supports multiple monitoring methods across various devices
• Instantly displays overloaded vehicle information on the software and sends SMS/email to competent authorities
• Provides detailed statistics on vehicle load monitoring down to each axle, with images and intuitive charts

Operating principle of the smart vehicle weighing system

When a vehicle enters the weighing platform, the monitoring software will automatically detect the vehicle on the scale and activate automatic license plate scanning to identify vehicle information. The software will retrieve weighing data from the indicator and store it in the database for cross-checking with the weighing station management system at each site. Managers will receive reports from both software systems for reconciliation, helping minimize loss and fraud to the greatest extent possible.
