DSP-based automatic control system hardware platform of bridge-type crane

Abstract

A DSP-based automatic control system hardware platform of a bridge-type crane comprises a DPS control module, a signal generating module, two signal isolating modules, a relay module, a sensor module, a wireless communication module and a power supply module. The DSP control module and the signal generating module can generate a pulse signal of a needed frequency as a control signal of the crane. One of the two signal isolating modules separates the relay module from the DSP control module, and the other signal isolating module separates the signal generating module from a controlled target. The sensor module can measure the position of the crane, the swing angle of a lifting rope, and the rotational speed of a motor. The DSP control module carries out data interaction with the sensor module and a host computer through the wireless communication module. The platform uses a control program and communication protocols developed on the DSP control module, achieves remote control of the bridge-type crane, and realizes swinging eliminating and positioning control of the bridge-type crane based on track planning. Experiment results indicate that the platform can obtain good control effect and has high practical application value.

Description

technical field [0001] The invention belongs to the technical field of automatic control of nonlinear underactuated electromechanical systems, and in particular relates to a DSP-based hardware platform for an automatic control system of an overhead crane. Background technique [0002] Bridge crane is a relatively common assembly transportation tool. Its mechanical structure mainly includes three parts: cart, trolley and lifting hook, and is generally driven by an AC motor. In a standard crane workshop, they are mounted on a higher load-bearing beam, the cart moves along the track on the load-bearing beam, the trolley moves along the track on the trolley, and the hoist on the trolley can lift or lower the hook, thereby It is possible to transport goods to any position in the three-dimensional workspace. Because it occupies a small space at a high place, has a large working space, and has a strong load capacity and flexible operation, it is widely used in various aspects of i...
