基于PLC编程的花式喷泉毕业设计_精品.doc

摘 要 在游人和居民经常光顾的场所，如公园、广场、旅游景点及一些知名建筑前，经常会修建一些喷泉供人们休闲、观赏。这些喷泉按一定的规律改变喷水式样，如果再与五颜六色的灯光相配合，在和谐优雅的音乐中，更使人心旷神怡，流连忘返。本讲述的是如何利用PLC控制喷泉喷水方式，产生各样的样式 PLC，喷泉控制组态ABSTRACT The place which patronizes frequently in the tourist and there resident, before like the park, the square, the scenic site and some well-known constructions, will construct some eruptive fountains to supply the people leisure, watching frequently. These eruptive fountains according to certain rule change spraying of water model, if coordinates again with the colorful light, in with the harmonious graceful music, causes the human to be completely relaxed, forgets to return. As the rapid development of the programmable logic controller, it has been appied in the control field to meet the more and more demanding. With the advantages such as its high reliability and easy of use, it can simplify the design logic and programming. When controlment demand changing, the user just need to adapt the program, avoiding modify the design plan if needs to change the pattern and time of fountains. What this article narrated is how using the PLC control eruptive fountain spraying of water way, has all kinds styles. Fore patterns of the fountain were given. The distribution of PLC is input/output interface was described under those patterns. The external hookup and ladder diagrams were designed also in this paper. The configuration realization of the system was introduced. Configuration dynamic simulation was completed by communicating the configuration software and the PLC hardware of SIEMENS. Keywords: PLC，eruptive fountain，control system，Configuration 目 录 摘 要 I ABSTRACT II 第1章 绪论 5 1.1 课题研究背景 5 1.2 课题设计目的和意义 5 1.3 课题设计内容 6 第2章 系统控制方案的确定 8 2.1 花式喷泉的概述 8 2.2 系统设计基本步骤 9 2.3 系统控制方案 10 2.4 花式喷泉控制系统的原理图 12 2.4.1 多花样喷泉设计原理 12 2.4.2 多花样喷泉设计原理图 13 第3章 系统硬件设计 14 3.1 可编程控制器（PLC）的选择 14 3.1.1 PLC概述 14 3.1.2 PLC的选型 14 3.2 开关量输入模块的选择 16 3.2.1 开关量输入模块的选择 16 3.2.2 开关量输出模块的选择 16 3.3 水泵的选型 17 3.4 喷头的选择 18 3.4.1 喷头的介绍 18 3.4.2 各
