APPARATUS FOR TRANSFERRING WIRELESS CONTROL SIGNAL IN RECLAIMER/STACKER

摘要

PURPOSE: An apparatus for transferring wireless control signal in reclaimer/stacker is provided to prevent a cable from being cut when using a real cable by transferring a control signal of a reclaimer/stacker by a radio manner. CONSTITUTION: A communication conversion device(25) is connected to a programmable logic controller(21) for a reclaimer/stacker and a programmable logic controller(22) for a central operation room, and receives a control signal of the programmable logic controller for control of the reclaimer/stacker to convert the received control signal to an TCP/IP-based data signal. A radio LAN conversion device(24) is connected to the communication conversion device(25), and receives the TCP/IP-based data signal to convert the received signal into a radio signal. The radio signal is transmitted via an antenna(23). The radio LAN conversion device(24) converts a radio signal received via the antenna into a TCP/IP-based data signal and transfers the converted signal to the radio LAN conversion device(24).
