Abstract: Since the traditional automatic weather station usually only can acquisite some conventional meteorological data (for example: temperature, humidity, wind-force, etc), but can not capture the high-resolution image information of the automatic weather station, an image acquisition and transmission system based on high-resolution digital camera for automatic weather-station is designed by researching the Olympus digital camera and using CAMEDIA SDK 3.3 developed by Olympus. The acquisition and transmission of the local image information around the automation weather station is achieved by collecting the remote image information through the high-resolution digital camera and transfering it to data center by network. The application of digital camera in the system is analyzed emphatically. The automatic acquisition function of image data was realized. Keywords: automatic weather station; image acquisition; digital camera; network transmission
在氣象觀測中經常需要通過自動氣象站采集當地的天氣、環境等圖像信息供氣象分析使用,而通常傳統自動氣象站只采集溫度、濕度、風速等常規氣象信息,而對于現場空氣質量、能見度等信息的采集卻無能為力。系統設計的自動氣象站除了以上常規氣象數據外,還能夠采集高清晰圖像,并通過網絡傳輸至數據中心,用以分析當地的空氣質量、能見度等氣象情況。
1 自動氣象站圖像采集傳輸系統
自動氣象站圖像采集傳輸系統由戶外自動數據采集站和數據中心構成。自動數據采集站負責多種氣象數據和現場圖像數據的采集,自動站系統采用ARM為核心的主機,通過RS 485總線控制載有高分辨率相機的云臺移動方位[1-2]。高分辨率數碼相機通過USB數據總線與主機相連[3],拍攝的圖像數據可通過TCP/IP網絡或WiFi網絡傳輸至數據中心[4]。……
