Firstly, the responsive mechanism, system and the applications in electric power field of optical fiber Bragg grating sensors and distributed fiber sensing are analyzed, then the development direction is analyzed. Then, combined with the specific monitoring scenarios and parameters such as temperature, stress, vibration and gas composition analysis of pipeline, a multi- parameter state monitoring scheme for cable tunnel based on waveguide integrated gas detector and fiber grating accelerometer is proposed. It can reduce the intelligent monitoring cost of cable ducts, improve the maintenance, safety and management of cable tunnels and promote the rapid development of smart grid.
