Product Description
Axle Group Scale Type Low Speed Weigh In Motion System ±1% Accuracy
Low Speed Weigh-in-Motion (LS-WIM) is a vehicle weighing system that automatically detects axle load, axle group weight, and total vehicle and cargo weight by allowing vehicles to pass through the weighing area at a low and constant speed without coming to a complete stop. It is a mainstream dynamic weighing solution in the transportation sector.
Working Principle
When a vehicle passes over the weighing platform or embedded sensors, the load deforms strain sensors (bending plate or bridge-type sensors) to generate electrical signals. The controller collects continuous load waveforms, and eliminates disturbances caused by suspension vibration and road surface bumps through filtering and dynamic compensation algorithms to calculate axle loads and total vehicle weights close to the accuracy of static weighbridges. Combined with vehicle separators and axle identifiers, the system distinguishes individual vehicles and recognizes axle types, and outputs complete vehicle weighing data.
System Composition
- Axle group scale: Integrated weighing platform / bending plate weighing sensor (mainly strain type)
- Signal Acquisition Controller: Signal conditioning, analog-to-digital conversion and operation of dynamic weighing algorithms
- Vehicle Detection Unit: Infrared vehicle separator, axle identifier, ground induction coil
- Auxiliary Identification Unit: License plate recognition camera, video evidence collection equipment
- Background Platform: Data storage, report generation, overload alarm and network upload interface

Application Scenarios
- Weight-based toll lanes at highway toll stations
- Re-inspection for overload control at highway overload inspection stations, freight terminals, ports and factory entrance/exit overload management
- Automatic weighing measurement for vehicles entering and exiting logistics parks, sand and gravel plants and mines
- Low-speed pre-inspection points for off-site law enforcement against overloading and over-limiting
