Abstract：In transmission line operation and maintenance, safety accidents frequently occur due to human error and negligence, creating an urgent need for efficient monitoring and data transmission technologies to ensure operational safety. To address the issues of insufficient safety awareness and irregular procedures in tower climbing operations, a novel anti-falling device is developed. The device utilizes a magnetically controlled triggering mechanism based on reed switches and magnetic rings, along with an electromagnetic locking system to prevent the simultaneous release of dual hooks. For real-time situational awareness, the system employs an ESP8266 module for wireless data transmission and bluetooth HC05 for communication between master and slave units. A BMP180 barometric pressure sensor is used for altitude measurement, the ATG336H module provides real-time positioning, and the A7670 module enables alarm triggering. Additionally, a cloud-based Onenet platform and mobile internet of things (IoT) terminal are developed to acquire real-time unlocking and altitude data, enabling operational assistance, behavioral regulation, and emergency response. Testing verifies that the device is functionally reliable and highly responsive, significantly enhancing safety in high-altitude power line operations and demonstrating strong potential for widespread application.
