西门子LOGO!控制系统的设计与编程

基于西门子LOGO！的真空泵自动控制系统设计本设计基于西门子 LOGO！的真空泵自动控制系统，主要实现对真空泵的自动控制，提高了生产效率，减少了人工操作。

下面将从需求分析、硬件选型、软件设计和测试验证四个方面进行详细介绍。

需求分析本系统需要实现以下功能：1. 自动打开和关闭真空泵；2. 实时监测真空泵的工作状态（如泵速、泵压）；3. 报警提示功能，当真空泵异常时能够发出警报，并记录异常信息；4. 根据生产计划进行自动化管理，能够自动调整真空泵工作时间，实现生产计划的自动化控制。

硬件选型本系统选用西门子 LOGO！作为控制器，真空泵直接连接在其输出端子上，可以实现对真空泵的控制。

同时，系统还需要具备一个实时监测真空泵状态的传感器，采用了压力传感器进行监测，并与 LOGO！控制器进行通讯。

此外，系统还需要一块人机界面屏幕，用于操作和监测系统状态。

软件设计本系统的软件设计分为两部分：PLC编程和人机界面编程。

1. PLC编程：主要实现控制器与真空泵、传感器之间的通讯和控制逻辑，包括打开/关闭真空泵、读取压力传感器的数据以及根据生产计划调整真空泵工作时间。

2. 人机界面编程：主要实现操作界面的设计和生产计划的管理。

操作界面需要实现打开/关闭真空泵、查看真空泵状态和记录异常信息的功能，生产计划管理需要实现设置生产计划和监测生产进度。

测试验证系统测试主要分为功能测试和性能测试两部分。

1. 功能测试：测试系统各项功能是否可行，包括自动打开和关闭真空泵、实时监测真空泵状态、警报提示和自动化生产计划管理。

2. 性能测试：测试系统响应速度、控制精度和可靠性等方面。

111西门子LOGO ！自动打铃控制系统王浩然（辽宁工程职业学院，辽宁　铁岭　112000）摘　要：随着时代的发展，目前的打铃系统多种多样，如多媒体中控系统、音乐电铃以及打铃器控制的电铃等，针对学院的实际情况，我们从经济性、可靠性以及操作难易程度上选择了PLC控制的打铃系统，本文主要介绍PLC控制的打铃系统的优点及系统组成。

关键词：学院；LOGO！；打铃一、PLC打铃控制系统的优点（一）经济性。

PLC即可编程序控制器，本系统我们选择的PLC是西门子公司生产的LOGO！控制器。

LOGO！是西门子公司生产的小型PLC。

LOGO！的全球唯一生产基地在中国南京，中国制造却发往世界各地，所以中国客户拿到的产品就代表着全球质量水准。

本地化生产给中国客户带来的就是更短的订货周期、更快的售后服务响应。

相比其他类型的PLC，LOGO！从选型到编程都力求精简，对用户的技术要求最低，而且相对中国市场主流的PLC价格更低，更加经济。

（二）可靠性。

因为PLC采用了大规模集成电路设计，不需要大量的活动元件和连线电子元件，它的连线大大减少。

与此同时PLC采用了一系列可靠性设计的方法进行设计。

例如冗余设计、断电保护、故障诊断和信息保护及恢复。

它具有比通用计算机控制更简单的编程语言和更可靠的硬件。

（三）操作简单。

本系统选用的西门子LOGO！集成了多功能显示面板，我们可以通过面板和组合按键来实现参数修改、系统监控、时钟调整等功能。

而普通类型的PLC及其他打铃系统则必须通过编程软件或专用的多媒体软件来实现。

（四）容易扩展。

西门子LOGO！的输入点可以针对打铃的控制方案来选取，比如日常打铃可以通过一路输入控制，当有考试时可以换另一路输入。

这样就可以通过选取输入点来控制输出，从而实现不同打铃方案快速切换。

如需要临时添加打铃方案，还可通过增加输入点来实现，操作简单，易于扩展。

二、系统组成针对以上优点，我们设计了以LOGO！为控制单元的打铃系统，本系统主要包括CPU模块（西门子LOGO!）、输入、输出模块、控制箱以及软件设计等几部分。

基于西门子LOGO！的洗衣机自动控制系统设计武永红张福顺杜立江（北京铁路电气化学校铁道电气化专业科，北京，102202）摘要：西门子LOGO!是介于PLC和继电器之间的可编程逻辑控制器，它适应控制技术市场细分的趋势，简单灵活，易于设计、维护。

本文采用西门子LOGO!作为全自动洗衣机的控制器，对整个系统进行了创造性的设计，方便了职业教育的控制技术教学，也为LOGO!步入洗衣机控制领域做出了有益的尝试。

关键词：西门子LOGO! 洗衣机自动控制设计LOGO！即可编程逻辑控制器。

它不同于PLC，不具备数学运算功能，但它本身集成了编程能力，且其带负载能力非常强，继电器输出的LOGO!，无须中间继电器与接触器，就可直接接入负载；它也不是继电器，其内部集成了多种继电器功能，外部接线极其简单。

它填补了继电器与PLC之间的技术空间。

随着控制技术市场日益细分，它以简单灵活，易于设计，易于维护逐渐赢得青睐。

为了适应日益细分的技术市场，我们整和现有设备，设计了基于西门子LOGO！的洗衣机自动控制系统，方便今后的控制技术教学，同时，也为LOGO! 创新性地进入全自动洗衣机的控制领域提供了技术参考。

图1．仿真调试界面１、系统总体方案设计概述本系统是在现有设备基础上，进行的改造性设计。

传统的洗衣机采用单片机控制，控制稳定，效率高，LOGO!虽然不如单片机功能强大，但是LOGO!的控制系统更加灵活简便。

在该系统中，我们采用LOGO!做为控制器，选用LOGO!230RC 。

洗衣机我们选用的是现有的海尔宁静型XQB45-A 全自动洗衣机，在拆除系统的单片机之后，保留电机、选择按键等其他设备部件。

按照LOGO!的接线方式设计解决方案，根据硬件电路，把LOGO! 接入洗衣机的基本电路中，完成电路搭建。

此外，由于LOGO!直接由交流220V 电源供电，所以，本系统就不同于单片机，不需要另设直流电源。

在搭建系统的过程中，我们采用LOGO!的配套编程软件在PC 机上开发控制系统程序，并进行仿真调试。

AbstractKeywords: Siemens LOGO!; Vacuum pump; Automatic control; Pressure sensor一、引言随着科技的日益进步，真空技术在工业生产、航空航天、医疗卫生等领域的应用越来越广泛。

真空泵是实现真空技术的关键设备之一，对其的控制和监测显得尤为重要。

目前，大部分真空泵的控制和监测还是采用人工操作的方式，存在着操作不便、控制精度低、实时监测不足等问题。

因此，需要设计一种能够实现真空泵自动控制和监测的系统，提高真空技术的应用效率和生产效益。

二、系统设计2.1 系统功能本文设计的真空泵自动控制系统主要实现以下功能：1）输入真空泵的目标压力值。

2）自动控制真空泵的启停，使其保持在目标压力范围内工作。

3）实时监测真空泵的运行状态，包括压力值和运行时间等。

4）通过液晶显示屏显示真空泵的运行状态和参数信息。

5）实现对真空泵的远程控制和维护，便于实际应用。

本系统采用以下硬件组成：1）真空泵：负责提供真空环境。

2）空气压缩机：用来驱动真空泵工作，保证其不间断连续运行。

3）压力传感器：用来检测真空泵的压力值，并将检测结果传输给控制器。

5）Siemens LOGO！控制器：根据压力传感器的检测结果和用户设置的目标压力值，自动控制真空泵的启停，控制液晶显示屏的显示内容等。

6）其他电气元器件：包括继电器、开关、线路等，用于连接各个硬件之间的电气信号。

2.3 系统设计思路系统的主要设计思路如下：2）用户通过液晶显示屏设置真空泵的目标压力值。

同时对在安装调试、维护使用中应注意的问题提出了有益的建议。

【关键词】真空泵；西门子LOGO！；可靠性0引言在锂电电池等制造行业，烤箱、搅拌机、自动注液机、封口机等设备必须在真空状态下运行，一旦真空系统出现故障，不仅只是维修真空泵的问题，而且生产无法进行，直接损失巨大，因此保证真空系统包括其控制系统运行的可靠性至关重要。

LOGO！即可编程逻辑控制器。

它不同于PLC，不具备数学运算功能，但它本身集成了编程能力，且其带负载能力非常强，只要选对型号，无须中间继电器和交流接触器，就可直接接入负载；它也不是继电器，其内部集成了多种继电器功能，外部接线极其简单。

它填补了继电器和PLC之间的技术空间。

以简单灵活、易于设计、易于维护逐渐赢得青睐。

1 控制系统的构成1.1基于西门子LOGO！控制的设计思想环宇集团海普赛能源科技有限公司真空系统由两台真空泵组成，原来的电气控制柜是继电器控制，各种继电器合计十余个。

由于继电器触点容易接触不良，时常出现故障，因此必须进行改造，原先准备改用PLC进行控制，这样可用软件代替大量继电器，只要程序写好，故障率会大大下降。

但是PLC各输入、输出端硬件接线线路都要经过公共输入、输出端，接线很不方便，同时PLC动辄几千元或以上，价格不菲，这就造成原料成本和安装成本很高，可是LOGO！市场价格才几百元，并且各输入点只要取自同一相电源即可，而输出又是继电器触点，没有公共端，这在硬件设计上相当自由。

在软件编程上又可将故障状态编成文本显示在显示面板上，并且给出输出报警。
