针对灌溉水利用系数较低,文中提出一种基于嵌入式智能灌溉控制系统。依托无线传感器网络采集灌区作物需水信息,汇聚到网关节点发送给主控中心,中心主机根据信息确定灌溉状态并计算灌水量,控制灌溉设备工作实现智能灌溉;依托Internet管理员有权对系统远程管理,满足了规模化灌溉的需求。根据示范区观测,灌溉水利用系数由原来的0.6提高到0.9。系统结合了无线传感、计算和网络通信技术,解决了精确农业亟待解决的关键技术问题。
Aiming at the low utilization coefficient of irrigation water, a control system based on embedded intelligent irrigation is proposed in this paper. Relying on wireless sensor networks to collect crop water demand information, collected to the gateway node sent to the control center, the center host according to the information to determine the state of irrigation and calculate the amount of irrigation, control of irrigation equipment to achieve intelligent irrigation; relying on Internet administrators have the right to remote Management, to meet the needs of large-scale irrigation. According to the observation of the demonstration area, the irrigation water utilization coefficient increased from 0.6 to 0.9. The system combines wireless sensing, computing and network communication technologies to solve the key technical problems that need to be solved in precision agriculture.
