The unmanned intelligent crane, in simple terms, refers to the overweight crane that combines intelligence and system. In practice, it can automatically complete the relevant requirements put forward by the enterprise. It has automatic management operation and management capabilities, and can simulate the actual operation of real people. In the process of continuous development and innovation of the actual market, the unmanned intelligent crane has a very broad space for development. The application of intelligent unmanned crane equipment helps to realize the conversion of traditional equipment to intelligent equipment.

The intelligent crane system has the anti-sway function and can be positioned automatically, and the positioning accuracy is very high; remote control and local control, remote monitoring, fault alarm, fault recording and reporting functions can be switched between fully automatic, semi-automatic and manual operation modes; Walking route self-learning, walking route customization, location customization, and location recording functions. The fixed-point grabbing technology is an indispensable technology applied in the intelligent crane steel plant, and it is of extraordinary significance to the production of the steel plant.

The intelligent crane fixed-point grasping technology applies the PLC system. PLC has high reliability, strong anti-interference ability, strong adaptability, flexible application, convenient programming, easy to use, and convenient control system design, installation, debugging, maintenance, and maintenance work. It has been widely used due to a series of advantages such as small amount. The advantages of the intelligent crane PLC system for on-site information collection, the modular programming of the system is carried out, and the entire program is divided into several functional blocks. Called in sequence from the main program, it is divided into Ethernet communication, equipment status detection, steel position coordinate fixed point in and out of warehouse, walking beam saddle position coordinate fixed point, straddle vehicle position coordinate fixed point, crane three-dimensional space coordinate fixed point, storage area obstacle The process of object information collection and device action command release is divided into program modules.
