【摘要】 针对本科自动控制实验教学需求,结合科研项目实践,根据现代无线智能灌溉系统需求,设计一种低功耗、高效的智能灌溉试验系统,实现智能控制实验教学。实验系统采用STM32芯片+(NRF24L01+PA+LAN)无线芯片组成的节点在多点采集数据,通过由低功耗STM32芯片、GPRS模块、低功耗NRF24L01+PA+LAN无线芯片及嵌入式操作系统Co OS组成的主下位机来汇总各点采集数据和全局控制;设计高效、简洁的通信协议来组建无线通信网络,当远距离控制或不在监控室时,主下位机能向用户的手机发送报警信息或者呼叫用户以提示土壤旱情,而且可通过手机发短信查传感器的监测值以及控制电磁阀,当在灌溉区时,可以通过手机的蓝牙来实现对灌溉的精确控制。更多还原

【Abstract】 Based on undergraduate experimental teaching needs of automatic control, combined with thepractice of scientific research projects, according to the needs of modern wireless smart irrigation systems, thelow power, high performance, intelligent irrigation systems is designed to fulfill experimental teaching of intel-ligent control. This system firstly uses the node made of chip STM32 and wireless chip NRF24L01 + PA +LAN to get data in a multi-point, then collects these data through embedded integration operating systemsCo OS of the main lower machine, achieves global control as well(the main lower machine includes low-powerchip STM32, GPRS module and low-power wireless chip NRF24L01 + PA + LAN). Based on network commu-nication, an independent development of efficient, simple communication treaty is used to set up wireless com-munication network. When the users are not in the irrigation district or the control room, the main lower ma-chine can send a warning message or make a call to the users to prompt the soil drought,users can also sendmessages to monitor the values of the sensor and control the solenoid valve. In the irrigation area, users can al-so use Bluetooth to control the entire irrigation system.更多还原
