There are several VR cameras 213, which are installed on the overhead crane main body 211. The number and installation position of the VR cameras 213 need to meet the requirement that the field of view can completely cover the entire working area of the overhead crane. The PLC controller 22 is connected to the overhead crane main body 211, and various instructions for controlling the overhead crane are preset in the PLC controller 22, which can completely control each component of the overhead crane. The terminal switch 23 is respectively connected to the general camera 212, the VR camera 213, and the PLC controller 22. A 5G industrial gateway that can communicate with the 5G base station 11 is installed on the terminal switch 23, thereby connecting the terminal module 20 to the 5G network.

[0018] When operating the system, the camera images are transmitted in real time through the 5G network. The status of the overhead crane and the surrounding environment are observed on the display device or VR glasses. Control commands such as trolley movement and hook lowering are input on the control device. The commands received by the control device are transmitted to the PLC controller 22 through the 5G network, and the PLC controller 22 controls the overhead crane to complete the control instructions.
