Title:
CONCRETE PUMP TRUCK AND BOOM CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2015/109975
Kind Code:
A1
Abstract:
Disclosed are a boom control method and a concrete pump truck, wherein the control method comprises acquiring an actuating signal of a remote controller, a current state angle signal of each boom section of a boom, and a rotation angle signal of the boom in real time; and planning the movement of the tail end of the boom. The method further comprises a prediction control, in which, according to the target moving direction of the tail end of the boom, the coordinate values of the tail end point of the boom are calculated in real time, if the tail end point of the boom deviates from the target moving direction, the tail end of the boom is arranged according to a secondary plan, and a next target point is output by means of the secondary plan. In this method, the tail end of the boom is arranged according to a secondary plan in the condition that the tail end of the boom deviates from the target moving direction, the probability that the boom stretches and contracts repeatedly and alternately is lowered, and the method has the advantage of the tail end of the boom moving stably.
