REMOTE CONTROL SYSTEM AND REMOTE CONTROL METHOD FOR DATA TRANSMISSION CONTROL NETWORK

摘要

PURPOSE: A remote control system and a method are provided to minimize system load in a remote server caused by data transmission by employing a data link controller. CONSTITUTION: A remote control system comprises a loop network(100) for connecting a plurality of connection devices(21-2x) such as computers through a link protocol corresponding to HDLC(high-level data link control)/SDLC(synchronous data link control) system; a DLC controller(30) connected to the loop network and which controls data receiving/transmitting operation between the network and connection devices in accordance with TCP/IP protocol; and a server(1) for remotely receiving the processed result from the DLC controller. The DLC controller includes an HDLC processor(32) with a built-in HDLC communication protocol for processing commands for data communication and operation control in accordance with HDLC system; an HDLC communication board(31) for transmitting/receiving data and operation control command processed by the HDLC processor; and a server interface(33).
