摘要
为了适应太阳能热水系统的大型化、智能化与工程一体化发展趋势,解决传统的单元型太阳能热水专用控制设备在人机交互、智能控制、远程监测、可靠性与扩展性等方面不能满足大型工程需要的问题,提出了基于PLC与人机界面触摸屏的太阳能热水工程水位测控方案,采用了PID控制变频器输出的方式,优化了系统控制策略、设计了友好的人机交互界面。实验测试与工程应用表明,该系统运行稳定,节能效果明显,能够很好的解决上述问题,具有很大的应用与推广价值。
In order to accommodate the trends that Solar Water Heating System become large-scale,intelligent and integration,solve the problem that traditional control unit of solar water heating system not adapted to technology requirement of large-scale engineering,in human-computer interaction,intelligent control,remote monitoring,reliability,scalability and networking.Proposing aprogram that water monitoring and controlling of solar water heating system based on PLC and HMI touch screen,using the way PID control output of frequency converter,optimizing control strategy of system,designing a friendly man-machine interface.It is showed that this system is stable,Energy saving is obvious,and it is a good solution to the above problems,by experimental testing and engineering application,that has great application and promotion of value.
