摘要： 针对小龙虾传统养殖过程中环境污染严重的问题，设计了一套将生态调控和智能调控相结合的基于LoRa技术的小龙虾生态养殖监控系统。系统通过循环调水模式，并且依据养殖生物间的互补共生共存原理，设计了“稻、草、虾”混合生态养殖模式。通过LoRa技术实现水质数据信息采集，根据模糊控制算法智能处理溶氧量，向下位机发出控制指令，并且通过4G路由器和云服务器共同搭建VPN，实现系统的远程控制。结果显示，利用LoRa技术可克服广域网存在的低功耗、短距离问题，系统显示中心运行正常，数据传输稳定。该方案具有通信距离远、部署简单、成本低的特点，且坚持绿色生态养殖理念，为水产养殖与物联网相结合的应用研究提供有效参考。

Abstract: In order to address the serious environmental pollution in the traditional aquaculture of crayfish, a LoRa-based monitoring system for crayfish ecological aquaculture that combines ecological control with intelligent control is designed. The system adopts circulating water transfer mode, and based on the principle of complementary symbiosis between cultured organisms, a mixed ecological aquaculture model of “rice, grass and shrimp” is designed. The water quality data information is collected by LoRa technology, the dissolved oxygen concentration is intelligently processed according to the fuzzy control algorithm, and the control command is issued to the lower computer. In addition, VPN is built through 4G router and cloud server to realize remote control of the system. The result shows that LoRa technology overcomes the problems of low power consumption and short distance in WAN. The system display center runs normally and the data transmission is stable. The scheme has the characteristics of long communication distance, simple deployment and low cost, and adheres to the concept of green ecological aquaculture, which can provide an effective reference for the application of aquaculture and Internet of Things.
