The online micro-meteorological monitoring system for power transmission lines collects multi-element meteorological data in real time along the transmission line corridor

Installed on power transmission towers, this system collects real-time data on wind speed and direction, temperature, humidity, air pressure, and rainfall. This data is wirelessly transmitted to the monitoring center, and alerts are sent to mobile phones in case of anomalies. It is suitable for use in long-span crossings, areas prone to icing, and areas with strong winds.

Specifically developed and manufactured for the local meteorological environment of transmission line corridors, the system allows for customized installation locations on the towers according to customer needs, enabling continuous environmental monitoring around the clock. The system collects six meteorological parameters in real time: wind speed, wind direction, temperature, humidity, air pressure, and rainfall. After collection, the data is transmitted to the monitoring center via GPRS or fiber optic wireless transmission. The platform analyzes the meteorological information in real time, and if the monitored values exceed safety thresholds, the system sends a risk warning to designated personnel's mobile phones, allowing maintenance personnel to take immediate action.

The online micro-meteorological monitoring system for power transmission lines employs a top-covered, concealed ultrasonic probe, reducing data deviations caused by rain, snow accumulation, and wind obstruction. It detects wind speed and direction by emitting continuously variable frequency ultrasonic signals and measuring the relative phase. The system features a six-element integrated structure with no moving parts, resulting in zero wear during operation. This highly integrated design reduces the overall size of the equipment and simplifies installation on towers. The sensing module has the capability to measure wind speed without startup and can accurately capture even subtle changes in airflow, ensuring stable and reliable sensor data acquisition.

The hardware circuitry includes a built-in watchdog circuit, automatically resetting and restarting the system in case of malfunctions. It exhibits strong anti-interference capabilities and can operate stably for extended periods on towers in complex electromagnetic environments. The casing is made of ASA engineering plastic, which resists fading and aging even after long-term outdoor exposure. The system is maintenance-free, eliminating the need for regular on-site sensor calibration and significantly reducing future maintenance costs.

The online micro-meteorological monitoring system for power transmission lines is mainly deployed in high-risk sections of lines, such as those with long crossings, areas prone to icing, and areas with strong winds. It fills the monitoring gap where large-scale meteorological stations cannot obtain local environmental data for tower locations. Relying on continuous and stable micro-meteorological data, maintenance departments can grasp the patterns of environmental changes along the line, proactively prevent safety accidents such as line galloping and line breaks induced by meteorological factors such as strong winds, icing, and heavy rain, and improve the overall safety level of power transmission line operation.
