卷扬机式闸门启闭机控制系统设计(含CAD装配图)(任务书,开题报告,外文翻译,论文说明书18000字,CAD图纸1张)
摘要
闸门控制系统是水库工程中的一个重要组成部分。随着自动控制、通信及计算机技术的不断发展,由人工操作的闸门,其控制手段和方法已日益不适应水利信息化的要求。过去的闸门主要依靠继电器逻辑控制,系统组成及接线复杂,继电器数量较多,投资较大、运行耗能较大,可靠性不高。
为适应当今整个社会经济蓬勃发展的需求，水利事业不断地得到发展。现代水利枢纽工程集防洪、抗旱、发电、航运、旅游等功能于一体，产生着巨大的经济效益和社会效益，它在保障人民的生活、安全和在交通、能源利用方面起着非常重要的作用。
且随着自动化技术和计算机控制技术的发展，卷扬起重机的控制系统也得到了极大的改善，自动控制领域较前沿的技术正逐步被应用到了卷扬机的控制系统中。在卷扬机控制系统的设计中，选用可靠性强的可编程逻辑控制器为核心对系统实现控制，这种控制模式已逐步发展成为卷扬机控制系统的主流。
为了提高闸门的工作可靠性及自动化程度，在原系统的基础上，提出用可编程控制器，利用行程开关，压力传感器，编码器等信号对闸门卷扬机，制动器实现自动化控制。本论文使用西门子S7-200系列可编程控制器进行控制，介绍了该系统的工作原理，并对其进行了总体设计和自动化控制系统设计。本系统方案简单且易于实现，该方法具有普遍意义，可广泛用于闸门控制。
本论文设计机械设计、电气控制与可编程控制器、组态软件等知识领域，是机械工程及自动化专业各科知识的综合应用。

Design of the Control System for the Hoist Type Gate Crane
ABSTRACT
Gate control system is an important component part of reservoir engineering. With the continuous development of automatic control, communication and computer technology, by the gate of artificial operation, the control means and methods has been increasingly don't adapt to the requirement of water resources normalization. The gate of the past relies mainly on the relay logic control, the system composition and the complex wiring, relay number is more, greater investment, operation energy consumption is larger, the reliability is not high.
In order to adapt to the needs of the whole social economy booming, water constantly. Modern water conservancy projects for flood control and drought resistance, power generation, shipping, tourism, and other functions into an organic whole, produce the huge economic benefit and social benefit, it is in the protection of people's life, safety, and in the use of transport, energy plays a very important role.
And with the development of automation technology and computer control technology, hoist crane control system has been greatly improved, and are more frontier in the field of automatic control technology is gradually being applied to the control system of hoist. In the design of the control system of hoist, selects the reliability of the programmable logic controller as the core to control the system implementation, this kind of control mode has gradually developed into the mainstream of hoist control system.
In order to improve the working reliability and automation degree of the gate, on the basis of the original system, put forward by programmable controller, using the travel switch, pressure sensor, encoder signal to a gate hoist, brake to realize automation control. This paper USES Siemens S7-200 series programmable controller to control, this paper introduces the working principle of the system, and carries on the overall design and automation control system design. This system is simple and easy to implement, this method has universal significance, can be widely used in the control gate.
This paper design the mechanical design, electrical control and PLC, configuration software, and other areas of the knowledge, is mechanical engineering and automation professional comprehensive application of knowledge in all the subjects.
