In order to solve the present dual contradiction of the low utilization of water resources in China's agricultural sector and the low land management efficiency,using Zigbee wireless sensor network and GPRS technology,this paper designs an intelligent monitoring system based on the GPRS and Zigbee wireless network technology. The Zigbee wireless sensor network is established based on the IEEE 802. 15. 4 / Zigbee protocol,consisting of terminal node for capturing and transmitting soil and environmental information to the coordinator node( gateway node)or acting the control command from the GPRS network. The irrigation remote monitoring network layer consists of coordinator node connected by the TCP / IP protocol,which can implement the precision irrigation of crops and the information management of arable land to the monitor center or user. And the monitor center using Java to write the system is safe and effective.
