A kind of crane intelligent voice remote control device

Abstract

The invention discloses an intelligent voice remote control device for a mobile crane. The intelligent voice remote control device of the mobile crane is composed of a remote controller, a mobile crane controller, a load sensor, a lifting frequency converter, a trolley frequency converter, and a large vehicle frequency converter. For non-specific voice control commands, the intelligent voice remote control device for mobile cranes can recognize "forward", "backward", "left", "right", "raise hook", "lower". "Hook", "Stop", "First Speed", "Second Speed" and "Three Speed" 10 non-specific voices, and convert these 10 voices into corresponding digital control instructions and transmit them to the crane controller for corresponding The mobile crane control realizes the voice wireless remote control of the mobile crane; the intelligent voice remote control device of the mobile crane also provides corresponding 10 button controls to realize wireless remote control of the mobile crane; the intelligent voice remote control device of the mobile crane realizes voice and button Combined wireless remote control and frequency conversion speed regulation.

Description

technical field [0001] The patent of the present invention relates to the wireless voice control of cranes, especially the voice command wireless remote control of decentralized drive gantry cranes and bridge cranes. Background technique [0002] Row crane is a common name for decentralized drive gantry cranes and bridge cranes, and it is a kind of lifting equipment commonly used in production workshops for lifting and transporting goods. The main girder of the gantry crane walks directly on the ground track, which is widely used in ports and freight yards; the horizontal frame of the bridge crane is placed on the elevated track laid on both sides of the workshop and warehouse, which can make full use of the space under the bridge to lift heavy objects. The forward and backward travel power of the distributed drive crane comes from the motor of the cart, the left and right travel comes from the motor of the trolley, and the lifting and lowering of the hook comes from the hoi...

Problems solved by technology

In use, the operator holds a wired or wireless controller to carry out operations, which is not only inconvenient to operate, but also takes up special operators, and the degree of automation is not high

In recent years, with the development of speech recognition technology, voice control technology has begun to be used by people, but the application of this technology is still blank in the control of mobile cranes.
