IPC: G01K11/12
Filed: 2001-08-10
Abstract: PROBLEM TO BE SOLVED: To measure road surface temperature at an optional position in the longitudinal direction and at a low cost. SOLUTION: An optical fiber 3 for temperature sensor and a metallic pipe (metallic long body) 4 are buried under road along its longitudinal direction while they are in contact with each other. The metallic pipe 4 is energized for heating, and a temperature Tf of the metallic pipe 4 as well as a changing rate ΔTf/Δτwith time elapse thereof during heating are measured by an optical fiber distribution type temperature measuring device using the optical fiber 3.
