系统设计为集成传感器清洁装置的水产养殖环境远程测控系统,设计采样箱将传感器数据采集及清洁装置集成一体;采用PLC为主控制器,完成对传感器清洁系统、增氧泵、采样水泵等可执行装置的控制;现场人机交互选用MCGS触摸屏,触摸屏作为主机,通过485总线实时采集传感器数据,实现测试数据的实时显示、储存及历史信息统计;PLC与触摸屏之间通过RS232总线通讯交换数据,同时PLC与GPRS模块GRM200G通过485总线通讯,将现场信息传到服务器,实现远程监控。试验结果表明,系统运行稳定可靠,操作界面友好,实现了对水产养殖水质参数的实时监测与远程监控。

Design of Remote Monitoring System of Aquaculture Environment with Sensor Cleaning

The remote monitoring system of aquaculture environment with data collection module and sensor cleaning was de-signed. The PLC unit with strong anti-interference ability was utilized to control sensor cleaning device, oxygen pumps, water pumps and other executable devices. MCGS touch screen was selected as Human-computer Interaction System, and the sys-tem based on MCGS performs real-time acquisition, display, recording and analysis for datum from sensors via RS485 bus. Communication between PLC and MCGS touch screen was realized through RS232 bus. Based on the communication between PLC and GRM200G GPRS data module which was realized through RS485 bus, field information was uploaded to the server, and the remote monitoring system was designed. The experimental results showed that the remote real-time monitoring of water quality was realized, and the system which offered a friendly user interface was stable and reliable.
