In the construction of transmission lines, the status of transmission towers is related to the safe operation of transmission lines. However, these devices are affected by harsh environments during long-term use, and various components, connections between components and the entirety will be damaged or deformed to varying degrees. Vicious accidents such as collapses often occur, causing huge economic losses and casualties. Therefore, it is imperative to monitor these large tower structures. At present, most of the related status information of the poles are monitored by wired or inspection methods, but the wired method is very inconvenient and not suitable for the monitoring of some towers in a harsh environment. The manual inspection method is not only expensive, but also not timely and accurate. Master the safety status of the tower. In these tower structures, bolts are an indispensable component, which are used to fix various components in large quantities, and play a very important role in the entire tower structure. In view of this, the company introduced a smart bolt that can monitor prestress. The bolt has an integrated pre-stress acquisition system, which can monitor the pre-stress transmitted on it in real time, and can transmit real-time data to management personnel in time, and can find out and take measures to solve it in time to prevent economic losses and casualties caused by the tilting and collapse of the tower.
