喷泉控制系统的设计
摘要:人工喷泉原本是西方园林建筑中的景观建筑，18世纪初叶正式传入中国。随着我国经济的不断发展，人民生活水平也日益提高，物质需求满足的人们越来越注重精神上的享受，喷泉这一事物因其观赏性高的原因走进了人们的生活。可编程控制器的发展使喷泉的喷泉式样变得多种多样，本设计使用了PLC作为控制器,通过西门子PLC200的编程软件STEP7设计控制系统控制喷泉的3种喷水方式，并且运用变频器使喷泉的喷水高度可调节，设计了I/O分配表和PLC的外部接线图以及控制梯形图。

The design of the fountain control system
ABSTRACT: Artificial fountain is originally the western landscape architecture landscape architecture of the early part of the eighteenth Century, was formally introduced into Chinese. With the development of China's economy, people's living level increasing, people pay more and more attention to meet the needs of the material and spiritual enjoyment, the fountain is such a thing because of its high ornamental reasons come into people's lives. Development of programmable controller to the fountain style become diverse, the design uses PLC as the controller, through the STEP7 programming software design 3 kinds of controlling the water fountain system Siemens PLC200, and the use of frequency converter to the fountain of spray height adjustable, designed the I/O allocation table and the external wiring diagram and PLC the control ladder diagram.
Key word: Fountain ; PLC; Control system; Water pump
