碩士 === 國立臺灣科技大學 === 電機工程系 === 105 === High-Voltage transmission lines are important components of power transmission since transmission towers as an essential role for high-voltage transmission lines. However, the structure of transmission towers after years of operation is susceptible to nature disasters. The continuing operation under abnormal situations, without troubleshooting, can cause deterioration and result in crises. In general, transmission towers adopt regular maintenance. The reliability of a power system can be improved if we constantly monitor the status of transmission towers. A transmission tower monitoring system can be divided into two parts which include the structural health monitoring and electrical health monitoring. This study will focus on the development of an embedded system for the monitoring of transmission towers. The main purpose of the system is to monitor the health status of towers bases, towers bodies and the surroundings. For the monitoring of towers bases, the potential sinking and inclination are to be detected. For the main body of a tower, structural deformation and inclination are to be detected. As for the surroundings, the movement of slope is to be warned. In order to reach the goal, the embedded system with a microcontroller is used. It effectively integrates the data from sensors. The data go through transmission and computation and then are saved onto a SD card and sent to a backend server and analysis module. They are also compared with the existing standards to show the health status. Finally, an embedded system prototype for the transmission tower health monitoring is developed and tested for its functional performance in order to verify the system feasibility.
