[0002] With the gradual popularization of IoT technology, intelligent building management has gradually come into people's view. Among them, tower cranes are essential equipment for large-scale construction projects. Their main function is to lift and lower materials. Traditional tower cranes still use a fully manual control method, which requires a lot of designated control buttons to control different functions of the crane. This results in a relatively complex control circuit, which makes it easy for the operator to make operational errors. In addition, it consumes a lot of electricity. Furthermore, most existing tower cranes achieve intelligent control through PLC, which makes it difficult to meet the needs of monitoring the position of the hoisted object. Therefore, improvements are needed. Summary of the Invention

Together with the intelligent control panel module 4, it constructs the three-dimensional spatial position information of the hoisted object. Meanwhile, the display module 9 can roughly display the deviation information between the hoisted object and its parking position, facilitating the adjustment of the hoisted object's position by the operator and achieving precise control of the hoisted object.
