Abstract: ObjectiveA remote monitoring cloud platform for soil moisture was designed in order to obtain real-time dynamic soil moisture information of maize field and irrigate summer maize in a scientific manner. It could provide reference for ensuring high and stable yield of summer maize.MethodRemote monitoring cloud platform for soil mois-ture adopted GPRS gateway to access the internet and formed local area network with 433 Mhz wireless. It was located in maize field of cities and towns in Henan Province,such as Yongcheng City so as to collect and analyze the information of soil moisture automatically.ResultThe cloud platform realized the real-time dynamic monitoring,online map position, historical data query,statistical analysis and text messages warning. Since 2015,the cloud platform has been widely used in Yongcheng City,Ruzhou City,Xihua County,Yuanyang County and other places in Henan. The test result indicated that the cloud platform achieved the aim of long-term real-time monitoring on variation of soil moisture in maize field. Through the analysis of soil moisture monitoring data,monitoring data could reflect the actual situation of maize field soil moisture.ConclusionIn conclusion ,the designed remote monitoring cloud platform for soil moisture can meet the requirements of soil moisture monitoring in maize field,and supply an online data collection and analysis platform for maize precise irrigation.
