Embodiment Construction

[0040] described in the prior art section above figure 1 .

[0041] figure 2 A block diagram of a monitoring system 20 according to one embodiment of the invention is shown. The system has a first type of sensor 21 for weighing the load on the carrier. The first sensor may be a strain gauge transducer at an articulation joint of the vehicle or a pressure transducer in a hydraulic cylinder, for example, the output signal of which is proportional to the load weight. The signal from the first sensor is directed to the electronics unit 28 with a wireless data transmitter or cable, and the signal is further amplified and converted into digital form in an analog-to-digital (A / D) converter 284 . The digital signal is read by processor 282 which calculates the weight value of the load.

[0042] figure 2 The monitoring system also has four sensors of a second type, preferably gyroscopes measuring angles, but alternatively the sensors of the second type may be other conventiona...

Abstract

This invention relates generally to a monitoring system of a material transfer vehicle. The present invention can be applied in weighing a load of the vehicle and in monitoring physical stability of the vehicle. The material transfer vehicle may be e.g. a wheel loader, a forklift, an excavator, a dumper, a forwarder, a harvester, a crane, a passenger hoist, a timber jack, or a truck such as a fire truck, a forklift truck, a pallet truck, a reach truck, or a garbage truck. The object of the invention is met by a solution, wherein a material transfer vehicle has at least one sensor for weighing and at least one sensor for measuring acceleration and/or angle of the vehicle or part of the vehicle in order to compensate the weighing data. In the inventive system a same part is used for both weighing a load of the carrying means and for monitoring a risk of overturning.

Description

technical field [0001] The present invention generally relates to a monitoring system for a material transfer vehicle. The invention may be applied to weighing the load of a vehicle, to monitor the physical stability of the vehicle and for other monitoring purposes. The material transfer vehicle may be, for example, a wheel loader, a forklift, an excavator, a dump truck, a conveyor, a harvester, a crane, a passenger elevator, a beam jack, or a truck such as a fire engine, forklift, yard pallet truck, reach truck or refuse truck). Background technique [0002] Material transfer vehicles typically include a weighing arrangement for weighing the material being handled or transported. figure 1 An exemplary material transfer vehicle according to the prior art is shown with a wheel loader 10 positioned on the ground 90 . The wheel loader has a bucket 12 as a carrier for the material to be conveyed. The bucket is connected to the body part / chassis of the wheel loader with an ar...
