Abstract

The invention discloses an embedded anti-sway method for a bridge crane, which belongs to the technical field of crane anti-sway. It includes the following steps: Step S1: provide a bridge crane system that also includes a rope encoder and an embedded module; Step S2, establish a mathematical model of the anti-sway acceleration of the horizontal running mechanism; Step S3, the embedded module passes through the rope encoder Measure the real-time length of the suspension rope of the bridge crane and the total mass of the hanging object; step S4, obtain the functional formula a(t) of the anti-sway acceleration and time of the horizontal running mechanism through the mathematical model in the embedded module; Step S5, the embedded module obtains the function formula v(t) of the speed and time of the horizontal running mechanism; Step S6, the programmable controller drives the horizontal running mechanism to run at the received speed through a frequency converter. It solves the problems of inaccurate open-loop control of traditional bridge cranes and high complexity, high cost and difficult implementation of closed-loop control of traditional bridge cranes.

Description

technical field [0001] The invention relates to the technical field of anti-sway cranes, in particular to an embedded anti-sway method for bridge cranes. Background technique [0002] Bridge cranes are an indispensable production tool for industrial production. With the development of society, users have higher and higher requirements for the safety, reliability, accuracy and stability of bridge cranes. During the loading and unloading process of the bridge crane, the hanging objects will sway due to the inertia, which seriously affects the production safety and operation efficiency. At present, the reduction of sway can be divided into three methods: manual anti-sway, mechanical anti-sway and electrical anti-sway. Manual anti-sway is to offset the sway by frequently controlling the acceleration and deceleration of the operator of the bridge crane according to the swing of the hanging object. Different bridge cranes operate The level of personnel is different, the reliabili...
