DANGE DIAGNOSIS SYSTEM OF POWER STEEL TOWER

摘要

A system for diagnosing danger of a pylon is provided to prevent the danger and secure reliability of a power transmission system by measuring and monitoring slope collapse and deformation of the pylon precisely with a hybrid type sensor and an optical fiber sensor. A hybrid sensor(110) includes a tilt sensor(120), a gyro sensor(130), a bearing sensor(140), and a microcontroller(150), and controls a state of each arm of a pylon. An optical fiber sensor(160) monitors the slope state of the pylon. A determiner(170) determines abnormality of the pylon by comparing correlation among data obtained from the hybrid sensor and the optical fiber sensor, and wind velocity data. A database(180) stores the previous data of the pylon. A server(190) performs a risk diagnosis for predicting the danger by using a result of the determiner and the data of the database. The tilt sensor is placed in an etched groove, and includes an electrolyte solution horizontal to the ground surface in a gravity direction and more than three electrodes immersed in the electrolyte solution. The tilt sensor measures the tilt of each arm by using different electric values according to an immersed depth of each electrode.
