Study of Optical Fiber Sensors in Temperature Testing of Locomotive and Railway Car

Presents a practical project of the optical fiber temperature sensor dependant of curved losses for use in temperature testing of the machanical refrigerated van, the air conditioned car and the oil-tanker van. Studies the information covert principle of the sensors, and establishes the mathematical mode. Uses the PCS multimode optical fiber as remote transfering line and seining probe. Introduces the system block diagram of the super intellectual distributed temperature sensor dependant of curved losses of the optical fiber, providesa new temperature testing method for the rolling stocks.
