介绍集约化水产养殖监控系统的设计和开发。阐述系统的功能、硬件组成以及软件设计。本系统以西门子S7—300PLC作为数据采集及控制单元,配合各种检测和控制设备对液位、温度、含氧量、pH值、电导及氨氮含量等检测量进行数据采集。上位机通过西门子的监控软件WinCC实现实时监控。经过系统调试与运行,该系统完全达到设计要求。
This paper presents a monitoring system for the intensive aquaculture, including the function of the system, the hardware components and the software design. This system takes the Siemens S7- 300 PLC as the data acquisition and control unit, and measures liquid level, temperature, oxygen content, pH value, conductivity, and ammonia nitrogen content with various detection and control equipment. Besides, it uses the Siemens WinCC software to realize monitoring. System commissioning and operation shows that this system meets the design requirements completely.
