The invention relates to a power supply complementary type on-line monitoring system and method, a line on-line monitoring device is charged in combination with solar energy, wind energy and high-voltage induction electricity taking by adopting a mode of complementing multiple power supplies, a backup battery utilizes a lithium battery and a super capacitor, the system judges the power of each charging power supply, finds a maximum power point, improves the charging efficiency and reduces the power consumption. Sufficient power supply of the device is confirmed. Meanwhile, deep discharging is carried out through the super capacitor, an energy storage method of the super capacitor is fully utilized, the super-long service life characteristic of the super capacitor is utilized, a power management scheme for prolonging the service life of the storage battery to the maximum extent is adopted, and the service life of the system is prolonged. According to the low-power-consumption power management technology of the
