Composition of automatic weather station
What is an automatic weather station:
Weather station is a device that can automatically observe and store weather observation data. It is mainly composed of meteorological sensors, collectors, communication interfaces, and system power supplies. As the value of the meteorological element 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, the conversion of engineering quantity to element quantity is realized. Then filter the data to get the value of each meteorological element. Weather station observation items mainly include air pressure, temperature and humidity; wind direction and speed, rainfall and other elements. The frequency of data collection is relatively high, and a set of observation data is collected and stored every minute. According to this, manual intervention of the automatic weather station. weather stations can also be divided into manned automatic stations and unmanned automatic stations.
The weather station uses 3G/4G wireless communication (GPRS) technology. The meteorological parameter data of the local area is automatically sent to the unmanned weather station of the central weather station. Automatic weather stations are generally set up in areas where conditions are bad and 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 in various regions and pass them through radio transmitters. Automatically and regularly sent to the central weather station hundreds of kilometers away. The central weather station can display the weather information in real time after receiving it, or record and store it for future 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. In some remote areas, due to inconvenient power supply. The automatic weather station can use solar power supply system and accumulator to meet the power consumption of the automatic weather station itself.
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. It has functions such as automatic recording, over-limit alarm and data communication.
