Weather station is an important meteorological observation facility, which is composed of main collector, sub collector, various sensors and power supply system. It can automatically observe surface meteorological observation elements such as temperature, humidity, pressure, wind speed, wind direction, rainfall, etc. To improve the timeliness and richness of the operation status monitoring of the weather stations and realize the remote control, a monitoring and control system is studied and designed for weather station. The system takes Raspberry Pi as the core to complete the hardware design and development of the weather station controller. And based on Python language, the software and controller program for monitoring and controlling the operation state of weather stations are developed. Finally, the reliability and power consumption of the system are tested and verified. The test results show that: The success rate of the system in obtaining the operation status of the automatic stations is above 99.5%, and it has a good ability to identify the abnormal operation state of the Surface meteorological stations. The average value of the controller is 3.9W, and the proportion of power consumption is 5.6% when the eight elements Weather stations are connected. But it should be considered to replace a larger capacity battery when used in the low-power consumption weather stations like two elements meteorological stations. The use of this system can further improve the operation quality of weather stations and reduce the work intensity of maintenance personnel.
