Title:
WELDING MACHINE SYSTEM FOR PREVENTING WELDING ACCIDENT BY USING POWER LINE-BASED LEGACY-LINE COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2018/016688
Kind Code:
A1
Abstract:
The present invention relates to a system for preventing a welding accident by using power line-based legacy-line communication. According to the present invention, the welding machine system for preventing a welding accident by using power line-based legacy-line communication comprises: a power control unit for controlling the supply of power; a welding device for receiving power from the power control unit through a first power line; a portable welding feeder for receiving power from the welding device through a second power line and supplying a welding wire at a predetermined speed; a wearable communication unit for receiving work position information and evacuation guidance information; a sensor unit, which is attached to the portable welding feeder and detects an emergency situation of the surroundings; a first communication unit, which is attached to the portable welding feeder, receives and delivers the work position information from the wearable communication unit and emergency situation information from the sensor unit, and delivers received evacuation guidance information to the wearable communication unit; a first signal coupling unit, which delivers information outputted from the first communication unit to the second power line, and collects information delivered through the second power line and delivers the collected information to the first communication unit; a first bypass unit for delivering information between the first power line and the second power line by bypassing the welding device; a second bypass unit for delivering information between the first power line and the outside by bypassing the power control unit; and a management server for transmitting the evacuation guidance information to the second bypass unit by determining whether an emergency situation has occurred for each work position on the basis of information received from the second bypass unit.
