Flat-type dynamic automatic weighing instrument for highway vehicles
The flat-plate dynamic automatic weighing device for highway vehicles is a dynamic weighing device that detects the vehicle load by detecting the change of the output parameters of the resistance strain sensor inside the weighing plate. When the freight vehicle encounters the weighing plate, the axle load acts on the force beam, causing the resistance strain sensor parameter change, and the axle load is finally calculated through the change of the output parameters.
Quartz dynamic weighing system
Quartz-type dynamic weighing system is a traffic information acquisition system that uses quartz piezoelectric as a sensor and integrates vehicle license plate, axle load, axle weight, axle type, vehicle speed, vehicle type, and flow. The piezoelectric sensor relies on the instantaneous charge generated when the vehicle passes to reflect the size of the vehicle axle load, which can fully reflect the actual weight of the axle load. The micro-deformation of the crystal sensor can be detected to generate a pure digital signal.
Mechanical combination structure, sensor individual and steel plate rely on physical structure, resistance strain principle, when the sensor is stressed to produce mechanical deformation, the size of the mechanical deformation to reflect the size of the force.
Overtime off-site law enforcement solutions
In the ordinary dynamic weighing pre-inspection scene, a single point only considers the situation of a single direction leading to the super-control station, that is, on a certain road, the points set up on both sides of the super-control station only detect the entry scheme and the exit direction.
