花样喷泉控制系统的设计 [摘 要] 本设计重点要解决的是花样喷泉的花样造型问题，要解决这个问题需要分为两部分，因此花样喷泉控制系统分为硬件和软件两部分，硬件部分主要是设计主电路图、外部接线图、控制接线图，软件主要是用可变程序控制器编写出所要的喷泉花样并且按照期望的顺序循环执行实现花样喷泉运行的自动控制功能，可靠性大大提高。花样喷泉采用了可编程序控制器和交流变频技术，变频器具有优异的调速性能.可以控制喷泉水位的高度，自动控制通过计算机运行程序发出控制信号，使水型按照期望的花样进行变化。 [关键词] 可编程控制器；花喷泉；变频器；水泵The Design of Synchronised Fountain Control System Electrical Engineering and Automation Specialty Hu Jing Abstract: What this design needs to solve with emphasis is the pattern eruptive fountain pattern modelling question, must solve this problem to need to divide into two parts, therefore the pattern eruptive fountain control system divides into the hardware and the software two parts, the hardware part is mainly designs the main circuit chart, the exterior wiring diagram, the control wiring diagram, the software is mainly the eruptive fountain pattern which compiles with the invariable program timer wants, and realizes the pattern eruptive fountain movement automatic control function according to the expectation order looping execution, the reliability enhances greatly. The pattern eruptive fountain has used the programmable controller and the frequency changer technology frequency changer has the outstanding velocity modulation performance. May control the eruptive fountain water level the altitude, the automatic control sends out the control signal through the computer run procedure, is the water type carries on the change according to the expectation pattern. Key words: Programmable controller; pattern eruptive fountain; frequency changer; water pump 目 录 1. 引言 1 1.1 本课题的研究背景 1 1.2 课题研究的目的和意义 1 2 S7-200系列PLC的介绍 2 2.1 S7-200 PLC的简介 2 2.2 S7-200系列PLC的选型 4 3 变频器的选择 5 3.1 变频器的特性 5 3.2 变频器的选型 5 4 花样喷泉控制系统的硬件体设计 6 4.1 花样喷泉系统的设计方案 6 4.1.1 喷泉概况 6 4.1.2 喷泉水泵、喷头布置 7 4.2 花样喷泉控制系统的硬件设计 7 4.2.1 花样喷泉控制系统的主电路图 7 4.2.2花样喷泉控制系统的结构框图 8 4.2.3 花样喷泉控制系统控制接线图和外部接线图 8 5 软件设计 11 5.1 花样喷泉控制系统的I/O 分配表 11 5.2 程序编写 11 5.2.1 梯形图 11 5.2.2 程序指令表 11 5.3 系统的调试与实现 11 结束语 13 参考文献 14 附录 15 致谢 271. 引言 1.1 本课题的研究背景 随着城市化进程的加速
