Working principle of automatic weather station

What is an automatic weather station:

An automatic weather station is a device that can automatically observe and store weather observation data. It is mainly composed of meteorological sensors, collectors, and communication interfaces. System power and other components. As the value of meteorological elements changes. The power output from the sensing element of each sensor changes. This amount of change is collected by a data collector controlled by the CPU in real time. After linearization and quantitative processing. Realize the conversion of engineering quantity to element quantity. Then filter the data to get the value of each meteorological element. Weather station observation items mainly include factors such as air pressure, temperature, humidity, wind direction, wind speed, and rainfall. After expansion, other elements can be measured, and data collection frequency is higher. A set of observation data is collected and stored every minute. Automatic weather stations can also be divided into manned automatic stations and unmanned automatic stations according to the manual intervention of automatic weather stations.

automatic weather station

Automatic weather stations can be widely used for weather monitoring in forests, scenic spots, farmlands, airports and other fields. It can monitor conventional meteorological elements such as wind direction, wind speed, temperature, humidity, air pressure, rainfall, soil temperature and humidity. With automatic recording. Functions such as over-limit alarm and data communication.

working principle:

The automatic weather station is an unmanned weather station that uses 3G/4G wireless communication (GPRS) technology to automatically send the weather parameter data of the region to the central weather station. Automatic weather stations are generally set up in harsh conditions. Areas where artificial weather observation stations cannot be established. The automatic weather station can collect and provide meteorological parameter information (such as temperature, pressure, humidity, wind force, wind direction, rainfall, etc.). Accumulate meteorological data of various regions. It is automatically sent to the central weather station hundreds of kilometers away by radio transmitter.

The central weather station can display the weather information in real time after receiving it. It can also be recorded and stored for later weather analysis and weather forecasting. Automatic weather stations generally use various sensors to automatically measure parameters such as atmospheric pressure, temperature, relative humidity, wind direction, average wind speed, maximum wind speed, accumulated rainfall, and precipitation phenomena. And transform the measurement result into a radio signal. Then sent to the central weather station by 3G wireless communication. In some remote areas. Due to the inconvenience of power supply. The automatic weather station can use solar power supply system and accumulator. Satisfy the electricity consumption of the automatic weather station itself.
