Recently, a technical exchange meeting for the ultrasonic meteorological observation station developed by Shandong Tianhe Environmental Technology Co., Ltd. was held in Weifang. At the meeting, many industry professionals and customer friends arrived at the scene. After understanding, everyone highly affirmed and fully recognized the product. Ultrasonic meteorological observation station is a modern equipment that uses ultrasonic technology to monitor meteorological elements. It has significant advantages such as high precision, maintenance free, and climate adaptability, and is widely used in various fields such as meteorology, agriculture, transportation, and environmental protection. By emitting high-frequency ultrasonic signals and measuring their propagation speed and time difference in the air, key meteorological parameters such as wind speed and direction can be calculated. Specifically, the built-in ultrasonic sensors in wind speed and direction measurement equipment (usually consisting of four probes in pairs) emit ultrasonic pulses, and accurately calculate the current wind speed and direction by calculating the time difference of sound wave propagation in different directions. When there is no wind, the propagation time of ultrasound between probes is the same; When there is wind, the wind speed will affect the propagation time, and the wind speed and direction can be calculated by the time difference. Temperature and humidity compensation sensors simultaneously measure air temperature and compensate for changes in sound velocity at different temperatures, further improving measurement accuracy. For example, as the temperature increases, the speed of sound accelerates, and the wind speed calculation results need to be corrected through temperature data. Some models of multi parameter integration also integrate sensors such as temperature and humidity, air pressure, optical rainfall, PM2.5, PM10, etc., to achieve integrated monitoring.

At the meeting, Manager Yu from Tianhe Environmental Technology Co., Ltd. introduced: "The core advantage of high-precision measurement ultrasonic technology is that it avoids friction and wear of mechanical components, and the measurement accuracy is much higher than traditional mechanical anemometers. It is adaptable to all weather conditions and is not affected by harsh weather such as rain, snow, and dust. It can work stably in the temperature range of -40 ℃ to 80 ℃, ensuring data continuity and integrity. Low power consumption and long life adopt low-power design (working voltage 10-30VDC), which can be matched with solar power supply system and suitable for long-term unmanned monitoring in the field. No mechanical components, low maintenance costs, and a service life of over 10 years. In addition to basic meteorological parameters, multifunctional integration can also be equipped with sensors for pollutant monitoring (such as PM2.5, SO ₂, NO ₂, etc.), noise, light intensity, etc., to meet diverse needs. Convenient data transmission comes standard with GPRS wireless transmission, supporting multiple communication methods such as RJ45, Ethernet, 4-20mA, LoRa, 4G, Bluetooth, etc. Data can be uploaded to the cloud platform in real-time for remote monitoring and early warning.

Typical application scenarios

Meteorology and climate research provides high-precision meteorological data for meteorological departments to support weather forecast, disaster warning (such as typhoon and rainstorm) and climate model research. Real time monitoring of farmland meteorological data (such as wind speed, temperature, humidity) in agricultural production helps farmers scientifically arrange irrigation, fertilization, and pest control, and improve crop yield and quality. Traffic management monitors wind speed and direction in airports, ports, highways, and other places to provide safety guarantees for traffic flow management, flight takeoff and landing, and logistics transportation. For example, a strong wind warning can prevent accidents during high-altitude operations. Environmental protection monitoring of air quality and wind field distribution, assisting in pollution source investigation and air pollution control. For example, tracking the diffusion path of pollutants through wind speed and direction data. The energy industry evaluates wind energy resources in wind farms, optimizes wind turbine layout and power generation efficiency. Real time monitoring of wind speed changes to prevent fan overload damage. Urban planning provides data support for urban ventilation design and green layout, improving the urban ecological environment. For example, optimizing building spacing through wind speed data to reduce the heat island effect. '

The exchange meeting was a complete success. We also welcome customers with such needs to come.
