Due to vast territories and complex terrain—from high-altitude mountains to valleys and over rivers—microclimate environments vary greatly. Transmission lines inevitably cross these areas with highly variable weather. In severe conditions like strong winds, heavy rain, or icing, these special geographical environments pose severe challenges to the stable operation of transmission lines, potentially causing serious damage, large-scale blackouts, and huge economic losses.
To address this challenge, the NiuBoL transmission line meteorological online monitoring system has emerged.

Transmission line weather stations are professional devices specifically designed for the power industry to monitor microclimate environments along transmission lines in real time. They feature high-precision sensors as the core, forming a complete meteorological environment perception network.
Definition: The NiuBoL weather station is a digitized, high-precision sensor system integrating ultrasonic wind speed/direction, temperature, humidity, air pressure, and other elements. It continuously monitors meteorological changes around the lines 24/7 and transmits data instantly to the control center.
Importance: Weather stations play a core role in disaster prevention and mitigation. By capturing anomalies in wind speed/direction and precipitation intensity in real time, the system can activate multi-channel alerts in advance, providing valuable response time for operations and maintenance personnel. This not only enables efficient allocation of resources for abnormal events but also fundamentally ensures the continuous stable operation of transmission lines.
The NiuBoL ultrasonic wind speed/direction multi-parameter sensor is a highly integrated, rugged environmental monitoring device. Its high-strength structural design ensures reliable operation in harsh climates from -40°C to 80°C.
The sensor uses fully digital ultrasonic detection technology to measure wind speed and direction, based on the time difference of ultrasonic transmission in air.
Basic Principle: Measure the transmission time of ultrasonic waves between two opposing sensors (e.g., N to S) and compare it with the reverse (S to N).
When wind blows from the north, transmission time from N to S shortens, while S to N lengthens.
Precise calculation of the time difference yields the wind speed component along that axis.
Similarly for W-E and E-W axes.
Vector synthesis provides accurate wind speed and direction.
Advantages: This time-difference method is unaffected by other factors (e.g., temperature, pressure), ensuring extremely high precision and stability.
Traditional tipping bucket rain gauges suffer from mechanical wear and high maintenance. NiuBoL adopts advanced piezoelectric ceramic kinetic rainfall monitoring technology.
Measurement Mechanism: Identifies and calculates based on kinetic energy from raindrops hitting the piezoelectric ceramic surface.
Raindrops fall at terminal velocity due to gravity and air resistance.
Using momentum theorem P = mv (P: momentum, m: mass, v: velocity), signal strength from impact determines individual drop weight.
System accumulates single drops to compute total rainfall.
Advantages: High resolution (0.01mm), high accuracy (±10%), monitors from light to heavy rain, no mechanical parts, simple maintenance.
The NiuBoL ultrasonic multi-element integrated sensor offers excellent specifications for demanding environments.

Proper installation is prerequisite for data accuracy. NiuBoL installation must follow World Meteorological Organization (WMO) recommendations to avoid turbulence and obstructions.
1. Specific Installation Steps
1. Positioning: Mount on a vertical tube, ensuring level measurement.
2. Tube Preparation: Drill 3 equidistant M5 screw holes 7.5mm from tube top.
3. Cable Routing: Pass cable through tube with strain relief.
4. Connection and Locking: Push rotary plug gently, rotate sleeve clockwise to lock.
5. Alignment (North Pointing): Use compass for true north, align instrument's north marker.
6. Fixing: Secure with 3 stainless steel screws.

| Common Fault | Possible Causes | Brief Troubleshooting/Solutions |
| No data output/communication failure | Unstable voltage; RS485 wiring error; protocol mismatch. | Confirm DC 9-24V; check A/B reversal; verify baud rate (9600 bps) and MODBUS. |
| High/fluctuating wind speed | Obstructions causing turbulence; near vibration sources. | Relocate to open area per WMO; away from vibrations. |
| Abnormal wind direction | Incorrect north alignment; poor shield connection. | Recalibrate with compass; check shielding. |
| Inaccurate/no rainfall data | Debris/dirt on piezoelectric surface. | Clean surface regularly; check for looseness. |
| Unstable operation/restarts | Insufficient current/poor power; substandard cable. | Use recommended cable; ensure stable power. |
