Transmission line micrometeorological monitoring system, the protection of power towers should not be delayed

transmission line micrometeorological monitoring system.

The guardian of micrometeorology.

Under the seemingly simple appearance.

It hides the magic of science and technology.

It's powered by solar panels.

No need to take care of it.

It monitors the weather around the clock.

Wind speed, wind direction, temperature and humidity.

Atmospheric pressure, rainfall.

The data is captured one by one.

Real-time transmission to the system host.

Storage, statistics, analysis without worry.

Power supply staff rely on it.

They can see the weather conditions at a glance.

Accurate judgement, reasonable arrangement.

Special patrol work is no longer confused.

It quietly pay.

Guard the stability of electricity.

It is the pearl on the tower.

Light up the road ahead.

Someone sent me a photo of the following picture, asking what the white gyroscope-like thing on the tower is.

I replied that it is a weather sensor. It's actually part of the transmission line's micrometeorological monitoring system. See that solar panel next to it? This is the system's energy device.

According to the information, I found the sensor related information -

Measurement of wind speed and direction: the principle is ultrasonic velocimetry. It consists of four ultrasonic converters, which are evenly distributed on the same horizontal plane on the circumference, forming a converter array. By measuring the forward and reverse transmission times of ultrasound waves in the east-west and north-south directions, the wind transducer is able to accurately calculate the wind speed and direction.

Temperature measurement: Diode junction voltage method.

Humidity measurement: capacitive sensing element measurement.

Barometric pressure measurement: Precision piezoresistive pressure sensor measurement.

Rainfall measurement: Using a PVDF piezoelectric film as a device for sensing raindrops, combined with an embedded AI neural network, it is able to accurately differentiate the signals generated by raindrops. This approach effectively avoids false triggering caused by external factors such as gravel, dust or vibration, and improves the accuracy of rainfall measurement.

The warning information issued by the meteorological department mainly serves the public, but the power grid equipment is mostly located in specific areas such as the middle of nowhere, and the meteorological conditions in these locations may be different from those of the overall region. Therefore, traditional meteorological monitoring and forecasting can hardly meet the special needs of power production and maintenance in terms of timeliness and accuracy.

Taking weather stations as an example, they are unable to provide accurate temperature and humidity forecasts for every neighbourhood or household, let alone real-time monitoring. Similarly, weather forecasts cannot provide accurate data for specific meteorological conditions (e.g., temperature, humidity, wind, etc.) at the location of a particular line or base tower. In order to get a more accurate picture of the operating conditions and health of transmission lines, power company employees install micrometeorological online monitoring devices on these lines to obtain real-time, accurate meteorological data.
