Problems solved by technology

[0003] The invention provides a system and method for monitoring the structural stress of towers, aiming at solving the occasional damage to towers of power transmission lines. The toppling of towers will cause serious consequences such as power interruption, affect the national economy, and cause personnel injuries. After the major changes in the tower structure, the maintenance department cannot obtain the changes in the tower structure in time and cannot take effective measures in time

Abstract

The invention belongs to the field of power systems, and provides a system and method for monitoring the stress of a tower structure. Strain gauge sensors are arranged on a main stress system, beams and columns of the tower structure and are used for monitoring the internal stress change in the tower structure. When the change in stress signals is captured, a microcontroller gives alarm signals, and the alarm signals are transmitted to a monitoring result alarm module through a wireless communication module; the monitoring result alarm module gives an alarm and can give early warning signals before a tower collapses and breaks, thereby maintenance departments are timely notified of taking measures before the consequences are caused by the greater change in the tower structure, the serious consequences of power interruption, personal injury and the like caused by the collapse of the tower when the transmission line tower is damaged can be avoided, and accordingly, the safety and the reliability of the operation of power facilities are improved.

Description

technical field [0001] The invention belongs to the field of electric power systems, and in particular relates to a system and method for monitoring the structural stress of poles and towers. Background technique [0002] In recent years, damage to power transmission line towers has occurred from time to time. The toppling of towers will cause serious consequences such as power interruption, affect the national economy, and cause personal injury due to natural aging, man-made destruction, natural disasters, etc. By monitoring the internal stress of the tower Changes can prevent problems before they happen, and notify the operation and maintenance to take measures to avoid accidents before major changes in the tower structure cause consequences. Contents of the invention [0003] The invention provides a system and method for monitoring the structural stress of towers, aiming at solving the occasional damage to towers of power transmission lines. The toppling of towers will...
