The invention discloses a trapezoidal turnout deformation monitoring system of a tramcar. The system comprises a deformation data measurement unit, a data acquisition unit and a management analysis early warning unit. The deformation data measurement unit comprises fiber bragg grating sensors (4) and a plurality of camera devices (5);the fiber bragg grating sensors (4) are arranged at the front ends and the roots of a stock rail (3) and a switch rail (3) and at the frog of a point rail (2) and are in deformation coupling with the rails, and the camera devices (5) are arranged at the point rail(1) and the switch rail (1) respectively. The data acquisition unit comprises an optical fiber data transmission module (8), a bandwidth light source (6) and an optical fiber grating regulator (7); and the management analysis early warning unit comprises an image processing module (10) and a data processing module (11). The invention further discloses a trapezoidal turnout deformation monitoringmethod of a tramcar. The trapezoidal turnout deformation monitoring system fills the blank of tramcar trapezoidal turnout deformation monitoring and is comprehensive and accurate in monitoring.
