Embodiment Construction
[0028] In order to make those skilled in the art understand the present invention more clearly, a more detailed description will be made below in conjunction with the accompanying drawings, but these descriptions are not intended to limit the protection scope of the present invention.
[0029] Such as figure 1 As shown, the working bucket leveling method described in the embodiment of the present invention includes:
[0030] Step S101: Receive the offset angle of the working bucket relative to the horizontal plane, and calculate the preliminary leveling output result Y according to the offset angle 1 ;
[0031] In this step, according to the offset angle, a closed-loop control algorithm including but not limited to a proportional-integral-derivative control algorithm is used to obtain the preliminary leveling output result Y 1 .
[0032] Step S103: Receive the load capacity of the working bucket, and correct the preliminary leveling output result Y according to the load cap...

The invention discloses a method, a device and a system for levelling a working basket and engineering machinery. The method comprises the following steps of: receiving a deviation angle of the working basket relative to a horizontal plane, and calculating according to the deviation angle to obtain a primary levelling output result Y1; receiving the load capacity of the working basket, and correcting the primary levelling output result Y1 according to the load capacity of the working basket to obtain a control signal Y; and outputting the control signal Y to level the working basket. According to the method, the device and the system for levelling the working basket and the engineering machinery disclosed by the invention, a load change caused by the change of the load capacity is introduced in levelling to correct the output levelling control signal, so that the levelling action is faster, more stable and more accurate, and the impact effect on the system for levelling the working basket generated by the change of the load capacity is reduced.
Description
technical field [0001] The invention relates to the technical field of construction machinery, in particular to a working bucket leveling method, device, system and construction machinery. Background technique [0002] In the special vehicle products with manned working platforms (also known as working buckets) such as aerial work vehicles, high-altitude fire trucks and automatic aerial vehicles, due to the boom lifting, amplitude change or windy conditions, the working bucket will The inclination of the bucket produces an offset angle, so a leveling system is required to keep or return the working bucket to a horizontal state. The leveling system is very important. Once the leveling system fails or the leveling fails, it may cause safety accidents such as the working platform tipping over and people falling. At present, the offset angle is generally fed back through the inclination sensor, and the automatic leveling of the working bucket is realized through closed-loop con...
