【摘要】：人们对生活质量的追求伴随着经济的不断发展而日益提高,同时在节能环保方面的意识也得到了进一步的提高。这使得人们在注重产品质量的同时更加注重能源的回收重复利用。就本文主要的研究方向——除湿干燥而言,除湿热泵的设计能够克服传统的电加热或者燃料燃烧加热等除湿方法所带来的耗能大、污染重的缺点。本文研究了基于ABB PLC的除湿热泵设计控制系统,进一步设计了系统总体控制方案和PLC控制程序,并且与触摸屏控制界面相结合,使之功能更为完善,并制作了触摸屏控制界面和实现了触摸屏对除湿热泵工作状态的监控,能够广泛应用于生活及工业生产中。具体研究内容如下:一、研究除湿热泵PLC控制系统硬件设计和设备选型。硬件部分包括:除湿热泵的选型、温湿度变送器的选型、PLC控制器的选型与设计、人机交互触摸屏的选型与设计。二、设计系统软件程序,包括:PLC程序编写和触摸屏画面制作。利用PS501编程软件实现PLC与温湿度变送器和触摸屏的通信等,实现了与温湿度控制器以及与触摸屏通信等功能。利用TouchWin组态软件完成温湿度记录及调节界面等的设计。触摸屏显示使得温湿度的监控更为直观,易于实现操作和控制,方便使用与维护。三、进行系统测试。对除湿热泵PLC控制系统的各个模块测试。测试结果表明所设计的系统能够在保证耗能较低的前提下满足对物料的干燥需求,表明所设计系统是有效和可行的。
[Abstract]:People's pursuit of quality of life is increasing with the development of economy. At the same time, the awareness of energy saving and environmental protection has also been further improved. This has made people pay more attention to the recovery and reuse of energy while paying more attention to product quality. The design of dehumidified heat pump can overcome the disadvantages of high energy consumption and heavy pollution brought by traditional dehumidification methods such as electric heating or fuel combustion heating. The design and control system of dehumidified heat pump based on ABB PLC is studied in this paper. Furthermore, the overall control scheme and PLC control program of the system are designed and combined with the touch screen control interface to make the function more perfect. The touch screen control interface and the monitoring of the desiccant heat pump working state are made and realized by the touch screen. Can be widely used in life and industrial production. The specific research contents are as follows: first, the hardware design and equipment selection of dehumidifying heat pump PLC control system are studied. The hardware part includes: desiccant heat pump type selection, Selection and design of PLC controller, selection and design of man-machine interactive touch screen. Including the programming of PS501 and the screen making of touch screen, the communication between PLC and temperature and humidity transmitter and touch screen is realized by using PS501 programming software. The functions such as communication with temperature and humidity controller and touch screen are realized. The design of temperature and humidity recording and adjusting interface is completed by using TouchWin configuration software. The display of touch screen makes the monitoring of temperature and humidity more intuitive and easy to operate and control. The test results show that the designed system can satisfy the drying requirement of materials on the premise of low energy consumption. It is shown that the designed system is effective and feasible.
