Abstract

The invention provides a crane control method. The crane control method comprises the following steps: a plurality of cameras are arranged; images in the step are acquired through an image acquiring module; packages output by the image acquiring module are received through an image processing module, and are decoded to corresponding output channels according to codes; displays display the images acquired by the cameras corresponding to the channels; a ground console comprises the displays and control hand levers; actions of operators are induced through the control hand levers; the positions of the control hand levers are induced through travel switches arranged in action grooves of all the control hand levers; pressure signals of the control hand levers are converted into electric signals through pressure sensors connected with the control hand levers; the two ends of electronic switch channels are respectively connected to the pressure sensors and AD converters; digital signal processors (DSP) are connected to the AD converters; and pressure coded signals are transmitted to an elevated control box of a tower crane.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a crane control method. Background technique [0002] Tower cranes are the most commonly used lifting equipment on construction sites. They are connected one by one and used to lift construction materials such as steel bars, corrugated wood, concrete, and steel pipes. [0003] According to whether there is a walking mechanism, it can be divided into mobile tower cranes and fixed tower cranes. [0004] Mobile tower cranes can be divided into four types: track type, tire type, car type, and crawler type according to different traveling devices. The tower body of the rail-mounted tower crane is fixed on the traveling chassis and can run on a specially designed track. It has good stability, can walk with a load, and has high work efficiency, so it is widely used in construction and installation projects. Wheel-type, truck-type and crawler-type tower cranes have no track device and ...
