摘要
花式喷泉是近年来出现的一种园林建筑与花式观赏相结合的一种产物。随着可编程控制器在我国的迅速发展，对花式喷泉的控制要求也越来越高，使得越来越多的控制部分需要可编程控制器来实现。
本文结合任务设计书的要求，以花式喷泉为研究对象，采用了S7-200 PLC作为喷泉的控制器。对花式喷泉的控制系统的总体功能进行了分析，阐述了可编程控制器的组成和工作原理。提出了喷泉硬件的各组成模块及详细的硬件模块设计方案，并对控制方式进行了设计和程序的编写。本设计改善了喷泉系统的控制品质，并真正地达到了实时控制的要求。

Abstract
Fancy fountain is a product of a kind of landscape architecture in recent years and combining the fancy watch. With the programmable controller in China's rapid development，fancy fountain control requirements are also getting higher and higher，they make more and more control of the programmable controller is required to achieve.
This text based on the mission design requirements, to fancy fountain as the research object，using S7-200 series PLC as a fountain of the controller。The overall function of fancy fountain control system are analyzed，this paper describes the composition and working principle of the programmable controller。The fountain of hardware modules and the detailed design of hardware modules，another ways of writing design and procedures。This design improves the fountain system, control quality, and truly achieve the real-time control requirements.
Key words: PLC; fountain; control system
