Problems solved by technology

[0005] The disadvantage of traditional systems is that they require additional complex components such as tape switches, cameras, radar or other position / speed sensing systems, which increases the likelihood of failure and reduces robustness

Embodiment Construction

[0040]The invention relates to a weighing scale and a method of weighing the scale. The present invention can be particularly applicable to high-precision vehicle dynamic weighing scale, such as LSWIM (Low Speed ​​Weigh-ln-Motion low-speed weighing motion) (5-10 km / h) scale and / or MSWIM (Medium Speed ​​Weigh-ln-Motion Medium speed weighing movement) (10-60 km / h) scale. Furthermore, the present invention relates to new or existing static scales designed for weight measurement, where the vehicle is stationary during weighing, by applying the present technical solution, this static scale can be converted for dynamic vehicle weighing.

[0041] As previously mentioned, the first group of conventional systems consisted of weighing scales with relatively short weighing bridges and therefore had problems with low accuracy. The low accuracy is due to poor averaging of swing weights, redistribution of load between bogie axles during travel and redistribution of load between axles durin...

Abstract

The invention relates to a method for weighing a vehicle and a weighing scale comprising a weighing bridge having first and second sides for entering and exiting the weighing bridge; a weighing circuit comprising a first set of load sensors coupled to a weight indicator, the first set of load sensors disposed on the first side, and a second set of load sensors disposed on the second side; a measurement circuit , for measuring at least one unbalanced current in said weighing circuit when a vehicle enters or leaves a weighing bridge; a processing circuit arranged to determine, based on said at least one unbalanced current, that a wheel of the vehicle enters a first side or At least one point in time away from the second side.

Description

technical field [0001] The invention relates to a weighing scale for weighing vehicles. Furthermore, the present invention also relates to a corresponding method. Background technique [0002] A road vehicle or rail vehicle is usually weighed to determine that the weight does not exceed limits set by regulators, such as maximum gross vehicle weight or maximum vehicle axle load on roads, railways or bridges. Another common application is to determine the cargo weight of a loaded vehicle. A first group of conventional systems consists of weighing scales with relatively short weighing bridges, ie shorter than the wheelbase of the vehicle. These systems typically have weigh bridges less than 1 meter in length, the usual short distance between the axles of the bogies of common vehicles such as vans and / or trucks (approximately equal to 1.3 meters), and monitor or weigh the weight of one axle at a time . Multiple weighings can then be performed and the results combined to dete...
