The invention discloses a power transmission tower attitude detection method and system based on a space-time frequency piezoelectric sphere, and the method comprises the following steps: arranging a plurality of piezoelectric sensing chips on the spherical surface of the space-time frequency piezoelectric sphere for sensing different three-dimensional sphere center angular forces and the acceleration of the sphere center angular forces; and the static attitude and the dynamic acceleration relative to a gravity line are calculated through ball space time-frequency signal processing. The space-time frequency piezoelectric balls are fixed at all positions of the tower column of the iron tower, and have fixed three-dimensional inclination information relative to the earth gravitational field during installation. Because each part of the iron tower has different local frequencies, the vibration type of the iron tower is judged by comparing the information of each module of the iron tower. Real-time data is compar
