四层电梯MCGS组态模拟
本资源利用MCGS组态软件来模拟实现四层电梯的控制,运行。PLC WORLD处理器为核心,综合了计算机控制、自动化、通讯网络等技术的一种通用的工业控制装置。PLC电梯控制系统有如下的特点:(1)、PLC是基于工业环境下设计的控制装置,环境适应性强,可靠性高;(2)、PLC最常用的编程语言是梯形图语言,编程语言形象、直观,编程筒单,便于广大现场工程技术人员掌握。(3)、門C控制系统的体积小,重量轻,便于安装,维修方便。(4)、PLC具有自诊断、故障报警、故种类显示等功能,可以方便的实时监视系统的运行状态。(5)、现代PLG具有传统控制系统无法比拟的远程数据传送、交换、控制和监枧的网络通讯功能。1.2系统结构和控制器选型电梯的PLC控制系统的结构如图1所示,主要硬件包括:可编控制器PL0、变频器、光电旋转编码器、轿厢操纵盘、厅外呼梯盘、门机及其他电气元件等。轿箱历外上位积操纵呼梯盘组态监控楼层显示申行接入部PLC部分串行接口2分门机编拽引机变频器码器图1系统结构图PLC WORLD1.3本次实习所选用的PLG机型?以及编程软件?S7-200可编程控制器是德国西门子公司研制的一种新型可编程控制器。它工作可靠,功能极其强大,存储容量大,编程方便,输出端可直接驱动2A的继电器或接触器的线圈,抗干扰能力强。因此,能够满足电梯对电气控制系统的要求。S7-200系列小型PG( MicroPL0)可应用于各种自动化系统。紧凑的结构,低廉的成本,强大的功能使得它成为各种小型控制任务的理想解决方案。在本次设计中,利用它编写控制一个四层楼电梯的控制系统分别完成轿厢内指令,厅外召唤指令,楼层位置指示,开门控制等任务STEP7WN32是S7-200系列的PLG编程软件,可以对S7-200的所有功能进行编程。该软件在 Windows平台上运行。其基本功能是协助用户完成应用软件任务。例如:创建用户程序,修改和编辑过程中编辑器具有简单的语法检查功能。还可以直接用软件设置PG的工作方式,参数和运行监控2.四层楼电梯模拟控制的设计控制要求(1)开始时,电梯处于任意一层。(2)当有外呼电梯信号到来是,轿厢响应该呼梯信号,达到该楼层时,轿厢停止运行,(轿厢门打开,延时3秒后自动关门)(3)当有内呼电梯信号到来是,轿厢响应该呼梯信号,达到该楼层时,轿厢停止运行,(轿厢门打开,延时3秒后自动关门)(4)在电梯轿厢运行过程中,即轿厢上升(或下降)途中,任何反PLC WORLD方向下降(或上升)的外呼信号均不响应,但如果反方向外呼梯信号前方再无其他内、外呼梯信号时,则电梯响应该外呼梯信号。例如,电梯轿厢在一楼,将要运行到三楼,在次过程中可以响应二层向上的外呼梯信号,但不响应二层向下的外哗梯信号。当到达三层,如果四层没有任何呼梯信号,则电梯可以响应三层向下外呼梯信号。否则,电梯将继续运行至四楼,然后向下运行响应三层向下外呼梯信号(5)电梯具有最远反向外呼梯功能。例如,电梯轿厢在一楼,而同时有二层向下呼梯,三层向下呼梯,四层向下外吇梯,则电梯轿厢先去四楼响应四层向下外呼梯信号。(6)电梯未平层或运行时,开门按钮和关门按钮均不起作用。平层且电梯轿厢停止运行后,按开门按钮轿厢开门,按关门按钮轿厢关门。3.I/0点的分配如下10.0S4四层内呼|10.7U1层上呼10.1S3层内呼11.0U2二层上呼10.2S2二层内呼11.1U3三次上呼10.3S1层内呼11.2SQ1层限位PLC WORLD10.4D4四层下呼11.3SQ2二层限位10.5D3层下呼11.4SQ3三层限位10.6D2二层下呼11.5SQ4四层限位Q0.0L4轿厢在四Q1.0SL2内呼二层层指示Q0.1L3轿厢在三Q1.1SL1内呼一层层指示Q0.2L2轿厢在二Q12外呼一层层上指示00.3L1轿厢在一Q1.3UP2外呼二层层上指示Q0.4DOWN轿厢上行Q1.4UP3外呼三层上指示Q0.5UP轿厢下行Q1.5DN2外呼二层下指示00.6sL4内呼四层Q1.6dn3呼三层指示下指示Q0.7内呼三层Q1.74外呼四层指示下指示4.PLC编程程序如下:4.1指令表:PLC WORLDsgLDsa22sq33sq1414Dsq0LD MO. 50MO. 4ALDLDSg2sq10MO. 5LDMO. 7M0. 6ALDOLDM2.0PLC WORLDsgdownLDMO. 7MO. 6ALDLD14sqdownM0. 6DMO. 5MO. 4ALDOLDM2.1MO. 2ANM3.0ownsq2sa3ANg4OLDPLC WORLDM3.3sg3sa2qAN MO. 5AMO. 7M2.0M3.3LDN MO. 2ANM2.7LDn sq 1AN213sqOLDM3.4g40sa3PLC WORLDsq200AAdownM0. 6MO. 3MO. 4LDM2.1M3.6OLDM3.4downd4sq4AL0ADd3sq3OLD20d22OLDusq

Title621.367-dc2l97-3803410987654321;4TWO-DIMENSIONALPHASE UNWRAPPINGFOREWORDTwo-dimensional phase unwrapping is the type of problem that is typically thedomain of the mathematician. It is both complex and abstract However, phaseunwrapping is also the core technology that enables radar interferometryOver the past decade interferometry has changed the way that we use radardata. Radar data are now used for precise measurement of surface topography inclouded regions. Additionally, spaceborne radar systems have proved effectivefor measuring surface changes from earthquakes and volcanic eruptions. Theseapplications have created a new class of radar data users primarily involved inmapping and remote sensing applicationIn Two-Dimensional Phase Unwrapping: Theory, Algorithms, and Softwarethe authors unlock the mystery of phase unwrapping in interferometric datarocessing. This text provides a clear, concise treatment of phase unwrappingthat cannot be found in any other source. It presents for the first time therelationship between theory and application. Its uniform treatment of thevarious phase unwrapping techniques makes it a valuable resource for anyengineer or scientist involved in processing or exploitation of interferometricexpect that radar interferometry will increase in importance over the comingdecade with the development of airborne and spaceborne sensor systemsdesigned to optimally exploit this tcchnology. Two- Dimensionsping: Theory, Algorithms, and Software is an important contribution to ourinderstanding of radar interferometry that will bencfit both research intoadvanced techniques and the design of these future sensor systemsJOHN C. CURLANDEPresident and CEOVexcel CorporationPREFACETwo-dimensional phase unwrapping arises most naturally in, but is notrestricted to, interferometric applications. Measured or calculated phasevalues from two or more mutually coherent multidimensional signals are relatedn a nonlinear manner to a desired physical quantity of interest. The nonlinearityis in the form of"wraps"or cycle discontinuities where an underlying two-dimensional phase is wrapped into the interval (T, r. The wrapped phasemust somehow be unwrapped in order to provide an estimate of the underlyingphysical quantity. Estimation of surface topography from interferometricsynthetic aperture radar(SAR)or extremely accurate profiling of mechanicaparts by optical interferometers are two such examplesOriginally developed for military reconnaissance, SAR is now experiencingnew life in civil applications. In fact civilian and commercial interests are rapidlbecoming the drivers of technology. Clever utilization of the coherent SArimagery in interferometric configurations makes possible the measurement ofsurface topography to accuracies much better than the spatial resolution( 0.3meters to several meters)of the SaR images themselves. Indeed, as is commonplace with interferometers, measurement sensitivities are on the order of theoperating wavelength, which is typically a few centimeters for SAR. Imaginggeometries, noise, and other operational factors degrade performance some-what from centimeter-scale accuracies, but nevertheless SAR interferometrymakes possible global topographic mapping in a timely fashion, in daylight or atnight, in all weather conditions, and with unprecedented accuracyinterferometry also can detect deformations of the earths crust on the orderof millimeters, a capability that shows promise for the timely detection ofearthquakes or volcanic eruptionsThese exciting possibilities have led to an explosive growth in the field of phaseunwrapping as indicated by the increasing number of journal publicationsNewcomers to SAR interferometry and related disciplines will eventuallyonfront the phase unwrapping problem and, undoubtedly, will encounter arather bewildering variety of ideas and algorithms, including those based onneural networks, simulated annealing, cellular automata, genetic algorithms,and other unusual constructs. Which of these are good? Which are not? We doThroughout this book we use the notation(-丌,丌 to represent the interval-丌
