In view of the shortages of traditional agro-meteorological observations and current automatic collecting techniques based on the sensors, an automatic collecting system of agro-meteorology information was built based on remote monitoring technique. Its total devices were composed of collecting front of the field microclimate, collecting front of the video, data collecting device, data transmission device and power equipment. The system highly integrated collection and transmission of the field microclimate data and video information, and automatically collected precipitation, air temperature, air humidity, wind speed, wind direction, photosynthetic active radiation, soil temperature, soil moisture and crop video information. The remote client software could achieve a real-time dynamic display and remote monitoring for all information. The test in Zhengzhou, Hebi, Wenjiang and Jingzhou stations showed that the system had a good performance in automatic collection, integrated transmission, real-time dynamic display and remote monitoring. It provided the basis for automatic identification, disasters information extracting and even crop yields estimation.
