基于Modbus协议的海水养殖监测系统的设计

A Design of Mariculture Monitoring System Based on Modbus Protocol

海水养殖需要密切注意水质变化,传统的人工监测方式存在准确率低、实时性差、效率低下等问题。为此,提出基于Modbus传感器设计大蚝养殖监测系统的方案。以STM32F103为控制核心,采用Modbus协议和RS-485总线控制SIN-D0530和YS8166B,实时采集海水的溶解氧、pH和水温,并通过上位机发送到Web服务器,便于用户随时随地获取现场信息。实践表明,该系统具有实时性高、成本低廉、稳定可靠、响应快速等优点。

Water quality is critical for maricuhure hence needs closelywatching. Traditional manual monitoring methods are not performing well in terms of accuracy, real-time performance and efficiency. Therefore, an oyster cultivation monitoring system based on Modbus sensors was proposed in this study. This system takes STM32F103 as the main chip,controls the SIN-D0530 and YSS166B via Modbus protocol and RS-485 bus, acquires real-time data of seawater＇s dissolved oxygen,pH,temperature and sends it to Web Server by upper computer, which allows users obtain real-time information anytime and anywhere. Practice shows that the system has the advantages of being low-cost, stable and fast-response and so on.
