摘要
针对目前国内水产养殖监控系统较落后的研究现状,设计了采用西门子S7—200PLC的循环水养殖温控系统,采用PID控制算法,对养殖池的水位和温度进行实时监控,实现养殖池温度和水位的恒定控制。详细介绍了系统的整体控制方案,工作原理,并给出了系统的软、硬件结构设计,有效地实现了系统的逻辑控制、安全控制、故障显示及故障处理。
Since study on the domestic aquaculture monitoring system was backward at present,the SIMATIC S7—200 CPU226 is used and adopted PID control algorithm to make real-time monitoring and controlling for the water level and temperature of closed circulating aquaculture system,thus it realized constant water level and temperature control in the culture pond.The system overall control scheme and principle are introduced in detail,and the system software and hardware structure design are given,the system has efficiently implemented system logic control,safety control,fault display and fault treatment.
