Abstract: Bring ZigBee technology into automatic control system of drip irrigation in field, making every controller terminal of system in field has capability of ZigBee communication, and founds a wireless Ad-hoc network in field, in order to remote control and collect system state. It is an energy saving plan in drip irrigation. So, design of a perfect function and high efficient ZigBee terminal controller is an indispensable and important link for large field drip irrigation. This paper gives a scheme of control terminal based on ZigBee wireless network, designs the controller hardware, software, and meets the requirements of large field drip irrigation. It makes the ZigBee wireless network in the drip irrigation technology better application.

Key words: field drip irrigation, ZigBee, wireless selforganizing, network terminal
