High-Speed Virtual WIM Scales | V-Wim Weigh-In-Motion Systems
Intercomp V-Wim (Virtual Weigh-In-Motion) weighing systems represent the state-of-the-art technology for high-speed, dynamic measurement of vehicle weights. These systems offer an ideal solution for traffic monitoring, in-road enforcement, and logistics applications where high throughput and accuracy are essential. V-Wim technology allows for the determination of vehicle axle and gross weights without the need for them to slow down or stop, thereby minimizing traffic congestion and increasing enforcement efficiency.
Key Features and Advantages
V-Wim systems combine reliability, speed, and user-friendly operation:
- High-Speed Weighing: The system is capable of weighing vehicles without them having to significantly reduce their speed, which is ideal for continuous traffic monitoring.
- Dynamic Accuracy: Advanced algorithms and sensors ensure the highly accurate determination of axle and gross weights while in motion.
- Modular Design: The system is flexibly configurable for various application needs, whether for fixed installation or portable solution.
- Integrated Software Solutions: Software for recording, analyzing measurements, and creating reports supports efficient data management.
- Robust Construction: The sensors and associated components withstand harsh weather conditions and mechanical stress caused by heavy traffic.
Application Areas
V-Wim technology can be widely applied in the following areas:
- Intelligent Transportation Systems: Traffic counting, weight-based tolling, and traffic management.
- Road Enforcement and Compliance: Identification of overweight vehicles without slowing down traffic.
- Logistics and Freight Hubs: Fast weighing of containers and trucks.
- Ports and Border Crossings: Accelerated inspection of border traffic.
Technical Specifications and System Components
Intercomp V-Wim systems are built to the highest industry standards. The main components of the system are as follows:
1. Weight Sensing Technology
The basis of the measurement is formed by high-capacity sensors optimized for high-speed weighing.
| Component |
Description |
| Sensor Type |
High-speed, low-profile strain gauge-based sensors. |
| Measurement Speed Range |
Capable of measuring across a wide speed range, often from 10 km/h up to 80-100 km/h (depending on the application). |
| Accuracy (Dynamic) |
Generally ±1% – ±3% for gross weight and axle load, depending on installation conditions. |
| Capacity |
Optimized for axle load measurement; the total vehicle weight is determined based on the sum of the axles. |
| Environmental Protection |
IP rated, resistant to water, dust, and extreme temperatures. |
2. Types of V-WIM Systems
Intercomp offers V-WIM solutions tailored to various installation requirements:
In-Road WIM Systems
These systems are designed for permanent, long-term installation, usually embedded into the roadway.
- WIM Platform Scales: Fully embedded, high-capacity platforms that provide excellent accuracy at fixed locations.
- LS-WIM® Axle Sensors (In-Ground): Discrete sensors integrated into the road surface that measure axle load.
Portable WIM Systems
Ideal for temporary inspection stations, requiring quick setup and relocation.
- LS788-WIM™ Portable WIM Scale: A system suitable for rapid deployment and high-speed measurement, ideal for weigh-in-motion screening or temporary checks.
- LS630-WIM™ Portable Low-Speed WIM Scale: Optimized specifically for low-speed measurement with excellent accuracy.
3. Indicators, Displays, and Software
Measurement processing and display occur through advanced indicators and software.
- Indicators and CPUs: Units performing the necessary calculations for measurement, often featuring a touchscreen display for ease of operation.
- Data Acquisition Software: They enable real-time recording of measurements, correlating vehicle identification data (e.g., license plate, timestamp) with weight data.
- Communication Protocols: They support various data transmission methods (e.g., Ethernet, serial communication) for connection to central databases.
Advantages of V-Wim Technology Compared to Static Weighing
Virtual Weigh-In-Motion (WIM) systems offer significant advantages over traditional, stationary measurement methods:
- Increased Throughput: Since vehicles do not need to stop, inspection points can process significantly more vehicles per hour. This is critically important on high-traffic highways and border crossings.
- Safety: The continuous movement of vehicles reduces the risk of accidents resulting from stopping and restarting, especially in high-speed applications.
- Reduction of Operating Costs: Fewer personnel are needed to manage the continuous traffic flow, and the measurement is automated.
- Data logging: WIM systems are excellently suited for collecting large-scale traffic data that can later be used for road network design and maintenance.
Ancillary Components and Support
Intercomp provides a comprehensive ecosystem for V-Wim systems:
- Load Cell Calibration Stands: Essential for regular calibrations and checks to maintain system accuracy.
- Accessories: Cabling, mounting hardware, protective covers, and other accessories for installation and long-term reliability.
- Application Solutions: Configurations optimized specifically for ITS/Compliance Checking, port/gate, or tolling applications.
Intercomp V-Wim weighing systems provide the highest level of reliability and performance for managing modern axle-weighing challenges.
