Description

Technical Field

[0001] This utility model belongs to the field of meteorological monitoring technology, specifically, it relates to a solar radiation meteorological monitoring device. Background Technology

[0002] Meteorological monitoring systems are important tools for obtaining environmental meteorological information and are widely used in various fields such as urban management, agricultural production, and natural disaster early warning. Existing meteorological monitoring methods are mainly divided into two categories: (1) using large-scale meteorological monitoring systems, which are usually deployed in cities or areas with good environmental conditions and can monitor meteorological data of the current area in real time. (2) using microcontroller-based meteorological monitoring systems, which are suitable for accurate detection of meteorology in specific areas. The detection data is stored in an SD card, and meteorological data is subsequently obtained by reading the SD card.

[0003] Currently, meteorological monitoring systems built at weather stations typically consist of a sensor section, a communication section, and a system power supply. The sensor section collects environmental information by sensing voltage changes in sensing elements, and then performs linearization and quantification processing to generate meteorological monitoring data. The communication section transmits the monitoring data to a computer or electronic device via industrial communication protocols. The system power supply provides power to the sensors, controllers, and computer. However, existing technologies have the following shortcomings:

[0004] (1) Power supply and distribution limitations: Weather stations are usually built in areas with convenient power supply. They are difficult to work properly in areas far from cities or with difficult power supply, resulting in the inability to accurately collect meteorological data.

[0005] (2) Environmental limitations: Meteorological stations are often located in cities and other areas with good environments. In areas with frequent natural disasters or harsh environments, existing meteorological stations are difficult to operate stably for a long time, and their reliability is challenged.

[0006] (3) Difficulty in meteorological station topology: The sensor structure of existing meteorological stations is relatively concentrated, and new meteorological element sensors cannot be directly expanded, resulting in insufficient upgrade and expansion capabilities.

[0007] (4) Limited meteorological data: The meteorological elements monitored by existing meteorological stations are mainly concentrated on basic indicators such as temperature, atmospheric pressure, humidity, wind and precipitation, while the collection of important data such as solar radiation is often neglected.

[0008] The above problems limit the application of existing meteorological monitoring systems in complex environments and high-demand scenarios, and there is an urgent need to propose an improved solution to enhance the stability, scalability and data diversity of meteorological monitoring systems.
