The invention discloses a fan blade attitude monitoring method and system based on inertial navigation and a medium, and the method comprises the steps: obtaining test parameters of each test point based on inertial navigation, the test parameters at least comprising a position parameter, a speed parameter and an attitude angle parameter; monitoring data of the attitude of the fan blade are obtained based on the test parameters, and the monitoring data at least comprise blade position data, blade rotating speed data and blade direction angle data; based on the monitoring data, a corresponding safety limit value is combined for comparison so as to output an operation report, and the operation report comprises an alarm report. The working state of the fan blade can be obtained based on the inertial navigation system, daily management of the posture of the fan blade is achieved through low-cost autonomous monitoring, and therefore alarm reminding can be output when the fan blade is abnormal, a user is helped to
