Hardware Design and Application of Internet of things for Rural Fishery Complex

围绕智能渔业融合创新以及改变传统渔业的养殖模式,文章研究了一套基于物联网技术的田园渔业综合体物联网管理控制系统,系统以STM32单片机为控制核心,外设增氧机、投料机、各类水质监测传感器等采集调控装置,选用稳恒科技研发的NB-IoT模组,以中国移动OneNET作为物联网工作的云平台,完成对pH、水位、温湿度、溶氧量数据的采集及处理,通过串口传送至NB-Io T模组,将数据通过LWM2M协议上报至云平台。云平台分析处理收集的数据与设定阈值对比从而下发动作,采集终端收到下发指令后进行投饵、增氧动作。系统可以远程精准投料,在规定时间内定时投料,提高了养殖效率。

Focusing on the integration and innovation of intelligent fishery as well as changing traditional fishery breeding mode, this paper studies a set of IOT management and control system for rural fishery complex based on Internet of things technology. The system takes STM32 single-chip microcomputer as the control core, and sets up acquisition and control devices such as aerator, feeder and various water quality monitoring sensors, selecting NB-IOT technology as transmitting mode, we exploit onenet of China Mobile as the cloud platform, and processing of pH value, water level, temperature and humidity, dissolved oxygen content data, and transmits them to NB-IOT module through serial port. The data to cloud platform is transmitted through LWM2 M protocol. The cloud platform analyzes and processes the collected data and compares with the set threshold value, so as to send the action. After receiving the command, the acquisition terminal carries out the feeding and oxygenation actions. The system can be remote accurate feeding, feeding in the specified time, improve the efficiency of breeding.
