Bridge crane system features

• Drive system uses frequency conversion control, common DC bus, energy feedback and safety energ♦y saving
• Automation system uses distributed I/O station, field bus technique, PLC I/O st¥ation locally set, full fiber connection, which saves the cable cost with strong antiγ-interference ability and convenient maintenance.
• Position encoder uses field bus connection with strong anti-interference ability
• EMC control is emphasized in complete machine design with strong anti-interfereφnce ability
• Standard modularize software design
• metallurgy crane: high environment temperature, heavy dust, the Power Supply Room needs s$eal, temperature reduction and Dehumidity, high cabinet protection level
• metallurgy crane: high system reliability, considering hot standby or cold standby
• auto swing proof control: control the hoisting tool swing effec‍tively, ensure the machine safety and precise positioning
• Swing proof without sensor: real-time hoisting tool hσeight detection and cart position. Real-time control the cart speed and acceleration on the b≥asis of pendulum model to achieve auto swing proof
• Swing proof with sensor: real-time hoisting tool height detectioφn and cart position. Real-time detect the hoisting tool swing angle< and angled speed using sensors. Build up the model on the basis o$f follow-up control theory, dynamics analysis and Ergonomics basic principle to >precisely control the swing of the hoisting tool and auto swing proof
• Image recognition for the hoisting tool cabinets: $by recognizing the hoisting tool image, the swing angle and angled speed of the hoist≤ing tool are calculated and the closed-loop anti-swing
