The farmland information monitoring generally has the characteristics of complex environment, more monitoring point and wide coverage. Wireless sensor networks technical is the main means to realize variables information collection of agricultural environment network. In order to solve the problem of reliable real-time transmission, a farmland information online monitoring based on wireless sensor network has been designed, which the ZigBee wireless communication technology was used. Monitoring data of different farmland regions are transmitted through the GPRS network to the monitoring center securely and reliably. The use of data monitoring center is aimed at collecting data for processing. The results show that the online monitoring system of field information can automatically complete the data acquisition and transmission throw GPRS network, the data can be sent to the data server with high stability, high reliability, punctuality, meeting the basic requirements of on-line monitoring of farmland information.
