一种基于LabVIEW的多功能机械臂末端执行器的软件架构的方案和验证
摘要
本文提出一种基于LabVIEW软件架构，用于控制离散事件系统。所提出的架构是生产者 - 消费者设计模式的变形。本方案使用多功能机械臂末端执行器的控制软件作为试验台来分析软件架构的适应性、使用限制和优点。该研究表明该架构在处理集成多种功能的控制系统的有效性。对于本文案例研究中，使用两个验证技术进行架构验证案件检查软件产品：（1）正式验证使用时间自动机和UPPAAL模型检查（2）一致性注入和故障注入的方法来决定软件测试的设置。两个验证技术确定了在编程阶段被引入到控制系统中的错误。
1 引言
本文讨论了设计和验证控制软件在LabVIEW离散事件系统的问题。本文的构思来源于航空工业的实际应用和用于多功能机械臂末端执行器的控制软件的发展。FARE（机身装配机器臂末端执行器）是巴西航空和工业技术的航空协会（ITA）之间合作项目的一部分。FARE的首要特点是作为一个有时间限制的离散事件系统。使用LabVIEW作为FARE控制系统的编程语言是航空公司的要求，因为它减少了开发时间，有与硬件设备的整合的可扩展性和易用性。LabVIEW已经广泛地图形化编程环境仪器仪表和控制应用中使用。但是，应用在
LabVIEW中离散事件控制系统的例子是不常见的。
离散事件控制系统的开发过程，通常基于诸如自动机和Petri建模技术网，应适应的图形化编程语言LabVIEW中。用于现成的解决方案模拟离散事件系统中，LabVIEW有一个状态图工具包、有限状态机和最近推出的状态图模块。因为这些解决方案为系统的限制拥有大量状态和转换，这项工作提出基于生产者 - 消费者设计模式的提案。
本文的贡献是对离散事件控制系统软件架构的建议、应用和验证。本文用机身装配机械臂末端执行器作为测试台分析软件体系结构的适用性和局限性、优点。关于该技术用于验证开发离散事件控制系统LabVIEW中的讨论也是本文的贡献。使用两个验证技术进行架构验证案件检查软件产品：（1）正式验证使用时间自动机和UPPAAL模型检查（2）一致性注入和故障注入的方法来决定软件测试的设置。两个验证技术确定了在编程阶段被引入到控制系统中的错误。
该验证方法的步骤如下图1所示。从软件需求出发，对部分版本FARE控制软件开发。对于相应的模型时间自动机的开发和验证。在时间自动机模型检测到的错误被用于校正的软件。同样的，CoFl的测试是使用由飞机制造商指定的并且施加到端部执行器的控制软件的部分版本的要求开发的。检测到的错误被编译在总结经验教训的清单，这是用于完整版FARE控制软件的开发。完整版提交功能测试进行最终审定。
本文还有以下几章。第2章讨论相关性工作。第3章描述所提出的软件架构。第4章介绍了FARE和它的控制软件。然后，第5章介
绍了对使用UPPAAL模型检测FARE软件的验证和基于CoFl模型的测试方式的应用。第6章是对本文的总结和未来工作的展望。
2 相关性工作
相关工作的审查的重点是两个主题：离散事件系统的控制和软件开发在LabVIEW中离散事件系统。本系统的执行终端没有安装向计算机回传数据的传感器,为了使仿真模型与实际机械臂同步运行, 作者通过软件编程来实现同步。
基本原理是:使控制指令(机械臂转动的角度值)同时被仿真程序和 控制程序执行,并在新指令到来时进行判断;若当前控制指令已经被仿真程序和控制程序执行完毕, 则传入新指令,否则进行等待,直到当前指令被执行完毕。
机械臂是一种可以运动的刚体，它需要一种数学方法来描述自身的运动特点，包括位移（距离）、速度、加速度等等。这种数学方法需要准确地描述机械臂的控制输入变量（关键角度）与输出变量（末端执行器）的关系。导出它的运动方程，至今，已成为标准的表示机器人和对机器人运动进行建模的方法。它以四阶方阵变换三维空间点的齐次坐标为基础的。为了描述机械臂与周围物体的关系，如抓取目标等，就需要学习刚体的坐标变换。
机械臂的运动学包括正向运动学和逆向运动学。正向运动学是指通过机械臂的各个关节的角度求取末端执行器的位置的问题；逆向运动学则恰好相反，已知末端执行器的位置，求取机械臂的各个关节的
角度的问题。
航天器机械臂典型故障的数字模拟包括机械臂模型的建立和故障模式的数字模拟。机械臂模型的建立包括机械臂几何尺寸、臂管材料的选取, 转动关节的设计,由运动学规划出发和回程轨迹, 以及动力学分析等步骤,同时也为两种故障模式的数字模拟提供了分析基础。故障模式的数字模拟是以所建立的机械臂模型为对象来模拟两种主要故障模式包括对机械臂工作的影响和表现特征, 也将为后面建立健康监控系统提供重要的依据。
臂管强度破坏的数字模拟。由前面已知条件和出发段、回程段各臂管的惯量矩阵, 便可做各臂管的动力学分析和应力分析。图 2(a )和图 2(b) 分别为出发段和回程段各臂管表面应力随时间变化曲线。可以看出应力主要在加速和减速时比较显著, 应力变化也比较明显, 匀速段应力几乎没有什么变化, 加速变匀速和匀速变减速时应力变化起伏很大。回程段臂管承受的应力比较大是因为回程段机械臂是负载着大质量的有效载荷运动的, 所以回程段的应力非常显著。因此, 故障诊断时应以回程段为重点, 特别是加速变匀速和匀速变减速的阶段。
本项目利用 LabVIEW 提供的三维参数曲面图形显示控件构建机械臂的三维仿真显示平台。静态建模时,先在 X-Z 平面内绘制出机械臂各杆件的平面图形, 构建一个包含各杆件平面坐标的数组(x i ,0,z i ),根据各杆件的尺寸比例将其沿Y方向平移y 后可得到一新的数组(x i ,y i ,z i )(此时,若将这两个数组传给三维参数曲面函数可绘制出一个

Virtual Instruments Based on Reconfigurable Logic
The emergence of virtual instrumentation is a revolution in the history of the development of measuring instruments. It fully utilizes the latest computer technology to implement and extend the instrument function. Using the image of a computer screen can be easily simulate a variety of equipment control panels to the needs expressed in the form of the output of test results. Using computer software to achieve most of the signal of the analysis and processing to complete a variety of control and test function. The user through the application of general-purpose computer program modules and features of the hardware together. Through friendly graphical interface to operate this computer. As in operating their own definition of individual instruments of their own design can be measured to complete the acquisition, analysis, determine, control, display, data storage and so on.
Virtual Instruments advantages of more traditional instruments:
(1)A strong integration of computer hardware resources. Breaking the traditional instruments in data processing, display, storage and other limitations, and
greatly enhanced the capabilities of traditional instruments.
(2)The use of computer software resources to achieve some part of the software of instrument hardware, saving material resources, increase system flexibility. Through software technology and the corresponding numerical algorithm. Directly on the test data for various analysis and processing in time. Through the graphical user interface technology, truly user-friendly, human-computer interaction.
(3)Hardware and software of virtual instrument is an open, modular, reusable and interchangeability characteristics. Therefore, the user can according to their own needs and use different manufacturers products. The development of the instrument system is more flexible, efficient and shorten the formation time of the system
The traditional instruments are application specific systems based on fixed hardware and software resources so their function and applications are defined by the manufacturer. These instruments are complex systems and therefore they become expensive and difficult to manage.
The widespread usage of personal computers in many scientific and technological fields make them an ideal hardware and software platform for the implementation of measurement instruments. By adding a simple data acquisition system, a personal computer can emulate any instrument. The instruments generated in this way are called virtual instruments because they do not have exclusive access to hardware and software resources. Different instruments can be implemented over the same hardware by only reprogramming the software. The virtual instruments offer plenty of advantages the most important of which is the low cost due to the reusability of hardware and software resources. The above characteristics and the continuous evolution and cheapening of the personal computers make the virtual instruments a valuable alternative to traditional ones.
Nevertheless, there are two main factors which limits the application of virtual
instruments. By one hand, the data capture is reduce to slow rates because of the more common operating systems of the general purpose computers are not oriented to realtime applications. By other hand, the data acquisition system is not an application oriented system but a generic one. Therefore, our proposal is focused on the enhancement of virtual instruments by the replacement of the generic hardware with a reconfigurable data acquisition system, as it is shown in Figure 1. By this way, some data process can be implemented by hardware reducing the data flow to/from the computer and rising the maximum sample rate.
基于虚拟仪器的可重构逻辑
虚拟仪器的出现是测量仪器发展历史上的一场革命。它充分利用最新的计算机技术来实现和扩展仪器的功能，用计算机屏幕可以简单地模拟大多数仪器的调节控制面板，以各种需要的形式表达并且输出检测结果，用计算机软件实现大部分信号的分析和处理,完成大多数控制和检测功能。用户通过应用程序将一般的通用计算机与功能化模块硬件结合起来,通过友好的界面来操作计算机,就像在操作自己定义，自己设计的单个仪器,可完成对被测量的采集，分析，判断，控制，显示，数据存储等。
虚拟仪器较传统仪器的优点
(1)融合计算机强大的硬件资源,突破了传统仪器在数据处理，显示，存储等方面的限制，大大增强了传统仪器的功能。
(2)利用计算机丰富的软件资源，实现了部分仪器硬件的软件化，节省了物质资源，增加了系统灵活性。通过软件技术和相应数值算法，实时，直接地对测试数据进行各种分析与处理，通过图形用户界面技术,真正做到界面友好、人
机交互。
(3)虚拟仪器的硬件和软件都具有开放性，模块化，可重复使用及互换性等特点。因此，用户可根据自己的需要，选用不同厂家的产品,使仪器系统的开发更为灵活，效率更高，缩短系统组建时间。
传统的仪器是以固定的硬件和软件资源为基础的specific系统， 这使得系统的功能和应用程序由制造商定义。这些仪器都是复杂的系统，因此它们变得昂贵而且难以操作和管理。个人电脑在许多科技领域的广泛应用使其为测量仪器的执行搭建了一个理想的硬件和软件平台，通过增加一个简单的数据采集系统，个人计算机可以仿真任何仪器。因为它们没有独自占有和访问硬件和软件资源，所以以这种方式产生的仪器被称为虚拟仪器。不同的仪器只要对该软件重新编程就可以在同一硬件中实现。虚拟仪器呈现了大量的优势，其中最重要的就是由于硬件和软件资源的重用性降低了成本。上述特点及虚拟仪器的不断发展和个人电脑降价使虚拟仪器成为传统仪器的一个有价值的替代。
然而，也有两个主要因素限制了虚拟仪器的应用。一方面，数据捕获的减少将放缓速度，因为一般用途的电脑普遍常用的操作系统并不面向实时应用。另一方面，数据采集系统不是应用导向系统而是一个通用的系统。因此，我们建议的重点是由通用硬件更换可重构数据采集系统来加强虚拟仪器，它如图1所示。通过这种方式，一些数据的处理过程可以通过减少计算机上硬件数据流和上升的最大采样率来实现。
