The invention discloses a solar anti-corrosion high-voltage line iron tower monitoring system of a power supply system. The solar anti-corrosion high-voltage line iron tower monitoring system comprises a tower head, a tower body and tower feet and further comprises a wireless tilt angle sensor, a temperature sensor, a video detector, a video control circuit, a solar assembly, a power supply battery, an anti-thunder module, a data processor, a date counter, a wireless transmission module which are arranged on the tower body, a wind power sensor arranged on the tower head and settlement monitors arranged on the portions, stretching into a concrete base layer, of the tower feet, the wireless transmission module is used for being connected with a monitoring center in a communication mode, and reinforcing ribs on the tower head can release transverse force and enhance the strength in the longitudinal direction of the iron power. The reinforcing ribs are arranged at an angle relative to the horizontal plane and can bear a part of transverse supporting force and ensure longitudinal rigidity. In the swing process of the iron tower, the reinforcing ribs arranged in a rhombus shape have certain resilience force, and the iron tower can be kept in a fixed posture and prevented from swinging at too large amplitude.
