Online icing monitoring device

Online Ice Monitoring Device

1 Overview

In winter, when the external temperature is below zero and rainfall occurs, water will adhere to high-voltage power lines and freeze. This reduces power transmission efficiency. As the ice layer thickens, the weight of the wires increases, placing greater tension on the transmission towers. If this tension exceeds the design load range, there is a risk of tower torsion and collapse. In response to this issue, 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, users can visually analyze data such as video, micro-meteorology, and tension. 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 can automatically collect data such as insulator string tension, insulator string angle, 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 a collection function for parameters such as battery voltage;

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

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 original collected quantities, deriving state quantity data such as tension and insulator string angle, and performing secondary calculations through an ice monitoring model to obtain 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-detection functions for the device's own working status, including collection, storage, processing, communication, etc.;

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

It has functions for identity authentication and remote program updating, with a complete 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.
