Crane control method and device based on electroplating production line

Abstract

The embodiment of the invention discloses a crane control method and device based on an electroplating production line. The crane control method comprises the following steps that a process tank is obtained by a contact request from a programmable logic controller; all crane information of the electroplating production line from the programmable logic controller is obtained; according to the craneinformation and the position coordinates of the process tank, a nearest target crane to the process tank is determined from a crane in an idle state and an automatic mode; and a response instructionwith the information of the process tank is sent to the target crane to control the target crane to move to the process tank to perform a corresponding process operation. The process tank interacts with the crane by a way to request a response through an upper computer, complicated operating lines of the crane on the electroplating production line are not required to be made in advance, each contact request can be obtained an optimal crane response in the fastest time, and the stability of crane control and the production efficiency of the electroplating production line are enhanced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of crane control, in particular to a method and device for controlling a crane based on an electroplating production line. Background technique [0002] At present, there are a variety of crane control modes used in the production line of the electroplating industry in my country, among which the fixed flow type and the open flow type are mainly used. These control methods are inseparable from the fixed crane trajectory mode. [0003] It is often easier to follow the trajectory of the cranes established in the early stage in the electroplating production line with a small number of cranes, and the operating conditions are ideal. But once the number of cranes exceeds 4 or more, it will be very difficult to plan the entire crane operation route, and if the number of cranes continues to increase, the difficulty of pre-planning the operation route will also increase, and the difficulty ...

Problems solved by technology

But once the number of cranes exceeds 4 or more, it will be very difficult to plan the entire crane operation route, and if the number of cranes continues to increase, the difficulty of pre-planning the operation route will also increase, and the difficulty will appear. geometric multiple growth

The more cranes there are, the more difficult it is to formulate the lines, which leads to the instability of the control program, and various problems such as crane sluggishness and collisions.

And this kind of problem will greatly affect the efficiency and even safety of the electroplating production line
