摘 要:针对传统水质监控系统中存在不能兼顾通信距离、通信成功率、调控精准度等问题,设计了一种基于长距离无线通信(LoRa)技术和窄带物联网(NB-IoT)技术的养殖塘水质监控系统。利用MSP430F149单片机和传感器实时采集水质参数信息,通过LoRa局域网传输参数信息至采集节点中心,利用NB-IoT进行数据汇总上传至中国移动物联网云平台(One-NET),开发了相应的微信小程序实现与云平台数据对接。云平台根据所得到的数据主动控制电气设备实现水质参数的调控。试验结果表明:通信成功率在98%以上,水质参数平均相对误差在0.5%以内,其他参数指标均符合要求。该系统保证了远程监控的实时性,提高了对水质参数调控的精准度。In view of the problem that traditional water quality monitoring system cannot take into account the communication distance,communication success rate and control accuracy at the same time,a water quality monitoring system of aquaculture pond was designed based on long range radio(LoRa)technology and narrow band internet of things(NB-IoT)technology.The MSP430F149 microcontroller and sensor were used to collect water quality parameter information in real time,and the parameter information was transmitted to the collection node center through LoRa local area network.The data was summarized and uploaded to China mobile internet of things cloud platform(OneNET)through NB-IoT,and the corresponding Wechat mini-program was developed to achieve data docking with the cloud platform.The cloud platform actively controlled the electrical equipment according to the obtained data to realize the regulation of water quality parameters.The test results show that the communication success rate is above 98%,and the average relative error of the water quality parameters is within 0.5%.Other parameters meet the requirements.The system ensures the real-time of remote monitoring and improves the accuracy of water quality parameters control.
