Crane remote operation system based on wifi wireless network

Abstract

The invention discloses a crane remote operation system based on a wifi (Wireless Fidelity) wireless network, which adopts a modular design and comprises three layers, namely a second layer configuration host PLC (Programmable Logic Controller), a first layer configuration host wifi module, a cab substation IO (Input / Output) module 1, other substation IO modules N, zero layer configuration wifi operation terminals 1-N, cab operation equipment and a mechanism driving execution unit, the second layer and the first layer are connected through a universal field bus FCS; according to the invention, the manufacturing and construction cost is low, the maintenance is convenient, only a plurality of wifi devices and terminals need to be added on the basis of the original control system hardware, and other parts utilize the original control system hardware of the crane, so that the new construction and transformation are convenient.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a remote crane operating system based on wifi wireless network. Background technique [0002] With the development of the national economy, large gantry cranes are widely used in shipyards and various heavy industries. [0003] The main body of a large gantry crane (gantry crane) is a gantry structure, usually the span between the legs on both sides is greater than 50m, and the height between the track surface and the bottom of the beam is greater than 60m. The driver's cab is located at the end of the main beam. The horizontal span of the working area is greater than 100m. [0004] Existing Problems: [0005] 1. Efficiency: [0006] Crane daily work objects; [0007] The Ground Operations Dispatcher is called: Subject A; [0008] The driver is called: Object B; [0009] Crane OS is called: Object C; [0010] The crane operation information flow is usually com...

AI Technical Summary

Problems solved by technology

[0012] 2) In the above-mentioned working space scale (usually the height between the track surface and the bottom of the beam is greater than 60m, and the horizontal span of the working area is greater than 100m), the driver cannot accurately observe the state of the hanging object

The operation instructions for the handling of hanging objects have been transmitted through manual radio intercom for many times, and there are problems such as error codes, delays, and individual differences in feedback.

[0014] 2. Cost:

[0015] There are 2 operators in the driver's cab, and there are labor costs

Driver's cab and personnel support facilities, such as driver's cab, rest room, elevator, etc., have additional costs for facilities
