The paper presents an innovative strain and temperature measurement method using the fibre Bragg grating (FBG) technology to monitor the design and operating safety of selected underground mining machinery and equipment. The system is based on the fibre Bragg grating (FBG) sensors or sensors using the optical time domain reflectometry (Optical Time Domain Reflectometry) technology. The essence of the solution is to introduce FBG sensors into the structure to make them act as its пїЅnervous systemпїЅ. Compared to c...
