SYSTEM FOR REMOTELY DRIVING CRANES BY WIRELESS COMMUNICATION

摘要

PURPOSE: A system for remotely driving cranes by wireless communication is provided to maximize a loading and unloading efficiency by driving four and five cranes in a remote operating cabin by a remote operation, automatizing the cranes, and reducing an operation cost. CONSTITUTION: Each of a plurality of crane regions(30a-30n) has cameras(34a,34b) and a control board(36). The cameras(34a,34b) photograph an internal portion of a yard crane in an upper portion. The control board(36) processes a control signal inputted from the outside, and controls the operation of motors(38). A remote control cabin has a plurality of operating computers(44) and a LAN(Local Area Network)(46). A plurality of the operating computers(44) receive image signals of the cameras(34a,34b), output the received image signals on a screen, and generate control signals. The LAN(46) mutually connects the operating computers(44). A communication device having APs(Access Points)(32,42) transmits and receives signals between a plurality of the crane regions(30a-30n) and the remote control cabin by wireless communication.
