【摘要】：为降低现有农业无线灌溉系统中控制节点的能耗,延长无线灌溉网络的生命周期,采用OOK调制技术,设计了一种低功耗唤醒装置,改变了当前无线灌溉系统中定时周期唤醒方式,减少了系统中开销,并实现了在4 3 4 MHz频段下无线灌溉控制器的研制。控制器主要由C8 0 5 1 F9 6 5单片机、电源电路、电磁阀驱动电路、唤醒电路、无线收发通道和开关量采集电路组成。该控制器由基站发送指令控制,根据距离远近,自适应寻址接收信号,实现实时采集和控制。经试验测得:额定容量为250m Ah的单节碱性9V电池,可使控制器工作一个灌溉季以上;与采用传统唤醒方式相比,系统不仅降低了能耗,而且提高了响应速度。
[Abstract]:In order to reduce the energy consumption of the existing agricultural irrigation system wireless control node in wireless network, prolong the life cycle of irrigation, using OOK modulation technology, design a low power wake-up device, change the timing wake-up mode of current wireless irrigation system, reduce system overhead, and realized in the development of wireless irrigation controller 434 MHz the band. The controller is mainly composed of C8 051 F9 65 single chip microcomputer, power supply circuit, solenoid valve drive circuit, wake up circuit, wireless transceiver channel and switch volume acquisition circuit. The controller is controlled by the command of the base station. According to the distance, the receiver adaptively addresses the received signal and realizes the real-time acquisition and control. The test results show that the single base 9V battery with rated capacity of 250m Ah can make the controller work for more than one irrigation season. Compared with the traditional wake-up mode, the system not only reduces energy consumption, but also improves the response speed.
