Online micro-meteorological monitoring device for transmission lines ensures the safe operation of the power system.

As a mature product in the domestic meteorological monitoring field, the Dongguan Lvguang QJ13 series micro-meteorological online monitoring device is backed by 17 years of dedicated research, development, and production of meteorological equipment. Through continuous technological innovation and market cultivation, it has become one of the key suppliers in the domestic meteorological and environmental monitoring sector.

I. Technical Core: Multidimensional Monitoring Capability of the QJ13 Series
The QJ13 series adopts a modular design, integrating real-time monitoring functions for seven core parameters: wind speed, wind direction, temperature, humidity, atmospheric pressure, rainfall, and solar radiation. Its wind speed measurement range reaches 0-60m/s with an accuracy of ±0.3m/s; temperature monitoring utilizes a platinum resistance PT100 sensor, with an error not exceeding ±0.2°C within the range of -40°C to 80°C. Particularly noteworthy is its innovative lightning protection design, which reduces the device's failure rate in thunderstorm-prone areas to one-third of the industry average through a three-level lightning protection circuit and grounding technology.

The built-in 4G wireless transmission module supports the TCP/IP protocol, enabling data to be uploaded to the cloud platform within seconds. The upgraded third-generation product adds LoRa wireless networking functionality, allowing multi-node network monitoring within a range of up to 5 kilometers. This technological breakthrough makes it particularly advantageous for applications in complex environments such as mountainous areas and offshore locations.

II. Deep Expansion of Industry Application Scenarios
In the power industry, the QJ13 series has been successfully applied in the Southern Power Grid's transmission line micro-meteorological monitoring system. By providing real-time monitoring of local microclimates, it enables early warnings of meteorological disasters. Its unique anti-electromagnetic interference design ensures data stability even in strong electric field environments.

Applications in the environmental protection sector are equally noteworthy. The monitoring network formed by these devices enables correlation analysis between meteorological parameters and water quality data within river basins, providing critical support for pollution source tracing. With an IP66 protection rating, the equipment can operate continuously for over 2,000 hours without failure in humid and dusty environments.

III. Industry Trends and Technological Evolution
With the advancement of the "dual-carbon" strategy, the QJ13 series is expanding into the new energy sector. The specialized version for photovoltaic power stations, launched in 2024, adds functions for monitoring the backplane temperature of components and assessing dust accumulation.

Over its 17-year development journey, Dongguan Lvguang has accumulated 27 technical certifications and participated in the formulation of 4 industry standards. The QJ13 series products have been exported to 12 countries along the "Belt and Road" initiative, becoming a hallmark of Chinese intelligent manufacturing in the professional meteorological equipment field. Against the backdrop of intensifying climate change, this high-precision, highly reliable micro-meteorological monitoring equipment is providing crucial meteorological data support to various industries.
