摘　　要：为了有效对农作物害虫进行绿色防控,解决现有系统普遍存在的声波频率范围窄和不利于野外环境实施等问题,结合物联网技术和DDS技术,设计了一种远程控制声波防治害虫系统。系统以STM32为主控芯片,通过DDS模块产生较大范围频率的声波,以达到防治不同种类害虫的目的。利用NB-IoT模块完成与手机APP的通信,实现远程控制;使用太阳能和电池双电源供电,并对电源进行有效管理,使电源利用率最大化。实验结果表明,通过对系统的软硬件进行优化设计,实现利用手机APP对系统进行远程监控,降低系统功耗,能够产生与预设频率值相比误差小于1%、频宽为60 kHz和功率基本稳定的声波。In order to effectively carry out green control of crop pests and solve the problems of the existing systems,such as narrow frequency range,and not good for the implementation of field environment,a remote wave pest control system is designed by Internet of Things technology and DDS technology.The system uses STM32 as the main control chip and generates sound waves with a wide range of frequencies through DDS module,so as to achieve the purpose of controlling different kinds of pests;NB-IoT module is used to complete the communication with mobile APP to realize remote control;the solar energy and the battery are used to supply power,the power is effectively managed to maximize the utilization ratio.By optimizing the software and hardware,the experimental results show that the remote monitoring of the system with the mobile APP is realized and system power consumption is reduced,and the system can produce sound waves with an error of less than 1%compared with the preset frequency value,a bandwidth of 60 kHz and basically stable power.
