Abstract

According to the present invention, a heating cable has a complex configuration in which an optical cable sensor is coupled to the heating cable to achieve the function of a sensor for sensing both a target object and the temperature of the heating cable with the result that the heating cable may serve as an active heat supply source capable of adjusting the output of the heating cable in accordance with temperature variations. To this end, an intelligent heating cable provided with a smart function according to the present invention is a heating cable for a heat tracing system. The cable comprising: a heating element, and an insulating outer layer formed on an outer surface of the heating element, characterized by having a structure in which an optical cable serving as a temperature sensor is coupled to the heating cable.

Description

technical field [0001] In one or more embodiments, the present invention relates to a smart heating cable providing smart heating and a method of manufacturing the smart heating cable, more particularly, the present invention relates to a smart heating cable providing smart heating, wherein the optical cable sensor ( Optical cable sensor) is embedded on the heating cable of the heating system, so that the heating cable has the function of sensing the temperature of the heating system to precisely measure the temperature of the part of the heating system that is not easy to sense the temperature, so as to properly Controlling the output of the heating cable, thereby reducing unnecessary energy consumption or preventing damage to the heating system due to insufficient heat supply, and a method of manufacturing the smart heating cable. Background technique [0002] Generally, heat tracing systems are used to compensate for heat loss caused by a piece of equipment or an object, ...
