文档介绍：基于PLC控制三层饭店送饭系统
摘要
随着微电子技术和计算机技术的迅速发展,PLC(即可编程控制器)在工业控制领域内得到十分广泛地应用。PLC是一种基于数字计算机技术、专为在工业环境下应用而设计的电子控制装置,它采用可编程序的存储器,用来存储用户指令,通过数字或模拟的输入/输出,完成一系列逻辑、顺序、定时、记数、运算等确定的功能,来控制各种类型的机电一体化设备和生产过程。
本设计主要介绍了PLC控制三层饭店送饭系统,由于PLC在自动控制方面有较大的优势,在这里我所以选用的是实现主要功能。
技术要求:每层设有其它两层的选层按钮。按下其中一层的选层按钮,选层信号被登记,其相应得选层指示灯亮。电梯可自动达到该层,待装完货且将厅门关好后,电梯自动消号并行至所选楼层。如电梯到达该层10s后未将门打开,其呼号被清除,其呼梯号被清除,电梯应答其它层呼梯号。当电梯处于检修转状态时,可通过慢上和慢下按钮点动移动轿厢。
控制要求:每层都有电梯位置指示功能有呼叫和功能有可靠的限速和限位功能
设计内容:设计电器控制原理图进行PLC选型及I/O口分配PLC控制程序的编写按要求撰写毕业设计说明书绘制设计图样。

Based on PLC control layer 3 hotel dinner system
ABSTRACT
With microelectronics technology puter technology to develop rapidly, PLC (programmable controller) in the industrial control area are very widely. PLC is based on a puter technology, designed for industrial application and design under the environment of the electronic control unit, it USES programmable memory, storage for user instructions, through digital or analog input/output, complete a logical sequence, timing, etc, operation of function, to control all types of electromechanical equipment and production process.
This design mainly introduces three layers of PLC control system, due to the restaurant meals in the automatic control of PLC has many advantages, here so I choose the main function is to realize.
Technical requirements: each layer with other two layers of selected layer button. Press one layer of selected layer button, choose layer, the corresponding signal is registered to choose layer indicator. Lift up the layer can be loaded with goods, and will be shut doors, hall, and runs away elevator automatically selected floors. Such as elevators reach this layer 10s not open the door, after their outcry be removed, the hall was cleared, elevator response other layer hall. When the elevator in turn, can repair by the slow and slow button at moving enclosure.
Control requirements: each layer has elevator position indicator function calls and function of the spee
