Sensor-information-fusion-based monitoring apparatus and method of transmission line tower

The invention relates to a sensor-information-fusion-based monitoring apparatus and method of a transmission line tower. The apparatus comprises a tower monitoring terminal arranged on a tower body; an input terminal of the tower monitoring terminal is connected with a torque sensor, an angle sensor, a strain tension sensor, a tilt sensor, a grating sensor, and a monitoring camera. An output terminal of the tower monitoring terminal is connected with a background work station and is used for transmitting tower situation signals monitored by the sensors to the background work station to carry out data analyses and matching. According to the method using the apparatus for monitoring, analysis results of the information monitored by the sensors and the information monitored by the camera are integrated to determine stability of the tower, so that the measurement result becomes accurate.
