Abstract
The present invention provides a boom system, comprising a plurality of joint arms sequentially hinged through a horizontal hinge shaft, and further comprising: mounting two length sensors on each joint arm, wherein one length sensor measures the length of a corresponding joint arm after deformation, and the other length sensor measures the length between it and the distal end of the corresponding joint arm, and there is a preset distance between the two length sensors; mounting a dip angle sensor on each joint arm, and obtaining the angle between the connection line between the two length sensors and a reference plane; a processor which obtains boom system distal end position parameters according to the detection results of the dip angle sensor and the length sensors. The boom system according to the present invention, for a single joint arm, uses a single dip angle sensor and double draw line coders to obtain the distal end position parameters of the joint arm, and can more accurately obtain the boom system distal end position parameters. The present invention also provides an engineering machinery and a boom system distal end position parameter obtaining method.
