Dual power supply solution for campus weather stations

Practical education places emphasis on the integration of the curriculum with actual practice, the unity of knowledge and action, and encourages students to learn and innovate by doing. By guiding students to participate in disciplinary inquiry activities, we emphasise interdisciplinary practice, allowing them to experience the process of discovery and problem solving, and to enhance their knowledge and skills. In this way, students' understanding not only comes from practice, but is also deepened in practice, avoiding the disconnection between theory and practice.

Campus weather stations include both automatic and manual types. Automatic weather stations can collect a variety of meteorological data in real time, providing accurate data support for scientific research and experiments. The artificial weather station, on the other hand, allows students to participate in observation and recording, cultivates their practical ability and scientific skills, and enhances their comprehensive quality.

The Campus Weather Station automatically monitors key meteorological elements such as wind speed, wind direction, rainfall, air temperature, light intensity, atmospheric pressure and so on around the clock. Through professional data acquisition communication lines, these data can be easily transferred to the meteorological database of the computer for subsequent statistics, analysis and processing.

The device can use a dual power supply scheme, i.e. 220V from the mains and a solar power supply system. During use, utility power will be the preferred power supply method. Once the utility power is interrupted, the system can automatically switch to solar power supply to ensure the continuous operation of the equipment and data integrity. This double safeguard design ensures both the online rate of the device and the continuity and integrity of the data.

The device supports a variety of output signals, including RS485, 4G full network and RJ45 Ethernet. Through RS485, devices such as PCLs, microcontrollers and computers can be connected; 4G Full Netcom supports wireless transmission to the cloud and connects to multiple transit centres for easy viewing of data on computers and mobile phones; and RJ45 Ethernet allows data to be transmitted directly to servers or designated LAN servers.
