on-line icing monitoring device

Online Ice Monitoring Device

1 Overview

In winter, when the external temperature is below zero and rainfall occurs, water will attach to high-voltage power lines and freeze into ice. This will reduce power transmission efficiency. As the ice layer thickens, the weight of the wires increases, and the tension on the iron towers also rises. If this force exceeds the design load-bearing limit, there is a risk of the iron tower twisting and toppling. In response to this, our company has designed the Online Ice Monitoring Device.

2. Working Principle

The Online Ice Monitoring Device is equipped with tension sensors, angle sensors, environmental weather station monitoring equipment, and image detection equipment. It can accurately assess the surrounding environment of transmission lines and ice conditions, reducing the possibility of false alarms. After collecting data, these front-end monitoring devices can send data IP packets to the monitoring center via wireless networks. By decoding the IP packets, data such as videos, micro-meteorology, and tension can be intuitively analyzed. If ice conditions are found to endanger the normal operation of transmission lines, timely responses can be taken.

3 Product Functions

The Online Ice Monitoring Device has the ability to automatically collect data such as the tension of insulator strings, the angle of insulator strings, temperature, humidity, wind speed, and wind direction at set time intervals. The minimum collection interval is more than 10 minutes, the maximum sampling interval is no more than 40 minutes, and the default sampling interval is 20 minutes;

It has a controlled collection function, which can respond to remote commands and start collection according to the set collection method, automatic collection time, and collection time interval;

It has the function of collecting battery voltage and other data;

It has a good synchronization mechanism to ensure the synchronization of the collection time of each parameter;

It has a data rationality check and analysis function, which preprocesses the collected data and automatically identifies and eliminates interference data;

It has a primary calculation function for the original collected quantities, obtaining state quantity data such as tension and insulator string angle, and performing a secondary calculation through an ice monitoring model to derive the equivalent ice thickness of the wires;

It can cyclically store state quantity data such as equivalent ice thickness for at least 30 days;

It has management and self-inspection functions for the device's own working status, including collection, storage, processing, communication, etc.;

When a device failure is detected, it can take corresponding measures to restore the device to normal operation;

It has functions of identity authentication and remote program updating, with a sound update mechanism and methods;

It has the ability to modify parameters such as collection frequency, sampling time interval, and network adapter address via remote commands;

It has the ability to dynamically respond to remote commands such as time query/setting, data request, and reset;

It can enter the remote debugging mode via remote commands and output relevant debugging information;

It can enter the remote debugging mode via remote commands and output relevant debugging information; Provincial company platform.
