Control method and device for barrier-free crossing of split-level crane

Abstract

The invention provides a control method for barrier-free crossing of a split-level crane. The split-level crane, a local field bus, a wireless communication module and a monitoring terminal are used in the control method. The control method for barrier-free crossing of the split-level crane comprises the following steps: acquiring the local position information, which is acquired by the local field bus, of a local crane, wherein the local position information comprises the position information of a local crane trolley and the position information of a trolley lifting point; acquiring the remote position information, which is received by the wireless communication module, of a remote crane, wherein the remote position information comprises the position information of a remote crane trolleyand the position information of a trolley lifting point; calculating an optimal safe crossing scheme according to the acquired local position information and the acquired remote position information;and controlling the split-level crane to carry out crossing according to the calculated safe crossing scheme. By the technical scheme, the optimal crossing route is planned automatically, potential safety hazards are reduced effectively, and the production efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of cranes, in particular to a control method for barrier-free crossing of a split-level crane and a control device for barrier-free crossing of a split-level crane. Background technique [0002] The lifting height of the cranes in large wharf yards or iron and steel enterprise workshops is high, and there are upper and lower cranes running through them. The lower crane trolley is its highest point, and the upper crane hook or load is its lowest point. The crane crossing operation position is not fixed, and there are various interference avoidance dimensions. At present, the safety control of crane crossing is very simple. The movement of the cart is restricted by the photoelectric switch, and the crossing passage of the upper and lower cranes is manually adjusted. Large and inefficient, it is easy to affect the safe and efficient production of enterprises. Contents of the invention [0003] Based ...
