可编程控制器和变频器在喷泉中的应用

Application of PLC Controller And Freguency Converter In Fountain

随着科学技术突飞猛进的发展,变频调速器技术正大步走进喷泉控制领域,发挥着不可替代的作用。特别是一些小型喷泉只有一台潜水泵,其变化按常规讲只能是喷或不喷的变化,但如果引进变频调速器技术,其变化将是极其丰富的。以北京工业职业技术学院广场喷泉应用变频技术,将一个手动控制的喷泉改造成自动控制喷泉为例,说明PLC控制器和变频器在喷泉中的应用。

Along with the development advance by leaps and bounds of science technology, the technology of frequency governor is stepping in the fountain control field fleetly, and having played an irreplaceable role. Especially, according to the normal regulations, the variety of some small scaled fountains, which has only one under water pump, is only spraying or not spraying. If the frequency governor technology, however, is imported, the variety will be very profuse. In this paper, the square fountain of Beijing Polytechnic College, which has been converted into an auto-control fountain by applying the converter technique from a manual control fountain, is an example of showing the applying of the PLC controller and the frequency converter in the fountain.
