Monitoring of Tower Body Inclination in Goaf Areas for Power Transmission and Transformation Projects

With the continuous expansion of power grid scale and the growing complexity of operating environments, the safe and stable operation of transmission line towers faces multiple challenges from geological disasters, foundation settlement, and other factors. Especially in goafs, subsidence areas, and sections with poor geological conditions, the tilt of towers is a key factor affecting line safety. To achieve real-time, accurate, and remote monitoring of tower tilt status, we have launched the independently developed Online Monitoring Device for Transmission Line Tower Tilt (TLKS-PMG-QX).

I. Product Overview

The Online Monitoring Device for Transmission Line Tower Tilt (TLKS-PMG-QX) is an intelligent online monitoring device specially designed for monitoring the tilt status of high-voltage transmission line towers. This device integrates high-precision sensors, a reliable data acquisition and processing unit, and advanced wireless communication technology, enabling real-time monitoring and reporting of changes in the horizontal and vertical tilt angles of towers. The product strictly follows the relevant technical specifications of the State Grid and China Southern Power Grid, has passed authoritative type tests, and has been successfully deployed in many practical engineering projects. It has stable and reliable performance and is an ideal choice for ensuring the safe operation of transmission lines.

II. Core Functional Features

1. High-Precision Real-Time Monitoring

Adopting a high-precision dual-axis tilt sensor, it monitors the horizontal and vertical tilt angles of towers in real time, with a measurement accuracy of up to ±0.05° and a measurement range of ±10°.

It has high anti-vibration capability (>20000g), ensuring the accuracy of data acquisition and equipment reliability under severe climates and external interferences.

2. Intelligent and Reliable Hardware Design

Embedded low-power design: Compact size and low power consumption, suitable for long-term field deployment.

Strong environmental adaptability: Wide operating temperature range (-40°C ~ +85°C), with an IP protection level of IP68, enabling stable operation in extreme environments such as severe cold, extreme heat, sandstorms, rain, and snow.

Solar power supply system: Uses solar panels combined with batteries to ensure continuous operation even in areas without grid power.

3. Flexible and Powerful Communication and Networking

4G Full-Network Communication: Built-in 4G wireless module, supporting adaptive networks from China Telecom, China Unicom, and China Mobile, with backward compatibility, ensuring wide signal coverage and unobstructed data transmission.

Intelligent network protocol: Supports dynamic/static IP, domain name resolution, and TCP/IP protocol, with a built-in security chip that supports encrypted data transmission to ensure data security and privacy.

Flexible triggers and interfaces: Provides two digital input/output channels, supports external switch triggers, and has multiple trigger start modes to meet the needs of complex scenarios.

4. Intelligent Data Management and Remote Control

Automatic acquisition and storage: Collects tilt data at regular intervals and stores it locally.

Response to remote data requests: Can respond in real time to data request commands from the background system and immediately report the current monitoring data.

Remote parameter configuration: Supports remote modification of parameters such as acquisition intervals and working modes, realizing "unattended" operation and maintenance management of the device.

5. Open and Compatible Platform Access

Seamless connection to superior platforms: Monitoring data can be stably accessed to the PMS (Production Management System) or unified monitoring platforms of provincial/municipal power companies.

Powerful software support: Provides PC and mobile client versions, making it convenient for operation and maintenance personnel to view real-time data, historical curves, and alarm information anytime and anywhere.

Excellent expandability: Designed with standard interfaces, it can be easily connected to video monitoring, image monitoring, or other meteorological and conductor status monitoring systems to build a comprehensive three-dimensional monitoring network.

III. Application Value

Prevent tower collapse accidents: Through continuous monitoring, timely alarms are issued when tower tilt exceeds the threshold, providing valuable time for emergency repairs and preventive maintenance.

Aid in disaster assessment: Provides long-term, objective data support for geological disaster assessment and governance effect verification in goafs and subsidence areas.

Optimize operation and maintenance strategies: Realizes the transformation from "regular patrol inspection" to "condition-based monitoring", reducing operation and maintenance costs and improving the intelligent and refined level of line operation and maintenance.

Ensure power grid safety: Provides a solid and reliable digital safety defense line for transmission lines, especially important lines in complex geological sections.
