Engineering plant and arm support control system thereof

Abstract

The invention discloses an arm support control system, which comprises a material object model (21), a control device (23) and an execution device (24), wherein the material object model (21) has a structure the same as that of an engineering plant, and is used for inputting a target position signal of an arm support (25) of the engineering plant by setting the model arm support state of the material object model (21); the control device (23) is used for receiving the target position signal, obtaining a movement path of the arm support (25) according to a preset control strategy and transmitting a control instruction; and the execution device (24) is used for controlling the arm support (25) to move according to the control instruction until the arm support (25) reaches a target position. The system provided by the invention improves the accuracy of control over the movement of the arm support of the engineering plant, increases an arm support state regulation speed, and prolongs the service life of the engineering plant. The invention also discloses the engineering plant and an arm support control method.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a boom control system for engineering machinery. The present invention also relates to a construction machine comprising the above-mentioned boom control system. Background technique [0002] With the increase of large-scale construction projects, the application of booms in various construction machinery is becoming more and more extensive. There are booms in construction machinery such as concrete pump trucks and cranes. In order to ensure that the boom can reach the target as required Position, usually in construction machinery is also equipped with a boom control system. [0003] Taking the concrete pump truck as an example, the boom control system in the prior art is described below: the concrete pump truck mainly includes a chassis, a power transmission device installed on the chassis, a pumping device and a stirring device, and a telescopic or inflected distribution p...

AI Technical Summary

Problems solved by technology

[0006] The above method adopts open-loop control, and only judges whether the boom has reached the predetermined position through the observation of the staff, and artificially selects the movement route of the boom. Therefore, the control accuracy is low, and when the boom is moving When controlling the boom, the operator needs to judge artificially according to the target position and the environment where the construction machinery is located, and give the movement route of the boom, which is not only very inconvenient, but also greatly affected by the operation process of the operator. It is not easy to ensure the accuracy of the boom movement; on the other hand, there will be some operational differences for construction machinery from different manufacturers. Working in an optimal posture will affect the service life of the boom
