Crane Product Performance Automation, Intelligence And Digitization
Apr 24, 2022
The renewal and development of cranes depends to a large extent on the improvement of electric drive and control. Combining mechanical technology and electronic technology, applying advanced computer technology, microelectronic technology, power electronic technology, optical cable technology, hydraulic technology, and fuzzy control technology to the mechanical drive and control system to realize the automation and intelligence of cranes.
The new generation of electrical control devices for large and efficient cranes has been developed into a fully electronic digital control system. It is mainly composed of fully digital control drive device, programmable logic controller, fault diagnosis and data management system, digital manipulation given detection and other equipment. Variable voltage variable frequency speed regulation, radio frequency data communication, fault self-diagnosis monitoring, fuzzy control of spreader anti-sway, laser search for the center of gravity of the lifting object, near-field induction anti-collision technology, field bus, carrier communication and control, contactless power supply and three-dimensional bar code technology will be widely used.
Make the crane more flexible, suitable for the flexible production mode of multiple batches and small batches, and improve the comprehensive automation level of a single machine. Focus on the development of high-performance electrical transmission devices with microprocessors as the core, so that the crane has excellent speed regulation and static and dynamic characteristics, automatic operation control, automatic display and recording, automatic protection and automatic detection of crane operation, special occasions remote control, etc., to meet the needs of automated production.
