Book Abstract

1．3 操作系统
平板电脑的运行依赖于操作系统。Android（安卓）是Google公司开发的开放源代码的操作系统，主要用于智能手机和平板电脑，是目前平板电脑最广泛使用的操作系统。本书介绍的平板电脑数控系统软件在Android操作系统下运行。
平板电脑数控系统软件是运行在Android操作系统下的一个应用程序，完成数控系统的所有实时控制计算和人机界面操作任务，控制数控机床或工业机器人的运行。Android同时还可以运行其他需要的标准应用程序，例如：文件管理、文字编辑、wiFi联网、多媒体程序等，它们为数控系统提供了丰富的辅助功能。Android是一个内置支持Java语言的操作系统，Android应用程序由Java编程语言编写和生成。
数控系统和其他自动控制系统的控制计算机以固定的定时周期控制系统的运行。它要求计算机操作系统和控制程序能够提供一个稳定的实时任务处理周期，在嵌入式控制系统中，也被称为中断处理周期。针对不同的控制系统要求，这个控制周期通常在1～100ms之间选择。作者在目前主流平板电脑完成的研究试验表明，当控制周期为25ms以上时，Antroid操作系统可以提供满足大多数控制系统要求的实时处理能力。本书将在第5章介绍编程方法和试验结果。
1．4 Java语言
Java是一种面向对象的计算机程序设计语言，广泛应用于互联网、PC计算机（包括平板电脑）、移动通信设备、多媒体设备等。在移动通信和互联网软件中，Java具有显著的技术和市场优势，成为这些技术领域的主要软件开发工具。
目前Java运行平台几乎已经嵌入到所有的主流计算机操作系统，其中也包括Android操作系统。用Java语言编写的程序可以在Android操作系统下运行，本书所介绍的数控系统软件编程方法和编程示例是用Java语言实现的。

Introduction

平板电脑（Tablet Personal Computer）发展迅速，已经成为目前广泛使用的个人计算机产品和移动多媒体设备。平板电脑是一个功能强大和丰富的计算机硬件平台，因此采用平板电脑作为工业自动化设备的控制计算机，具有结构紧凑、功能强大、价格低廉的优势，在工业自动化领域具有广阔的应用前景。
本书的作者团队（北京航空航天大学数控和伺服技术实验室）长期从事数控机床和工业机器人控制系统研究工作，包括软硬件平台、系统体系结构、控制算法、编程技术、设备控制现场总线等。使用平板电脑作为工业控制计算机平台技术是团队所密切关注的研究方向，并取得关键技术的突破。这些关键技术包括平板电脑与外部控制设备的接口技术、Android操作系统实时控制技术、Java语言数控系统软件编程技术、基于以太网芯片的控制设备现场总线等。在这些研究成果基础上，开发出了基于平板电脑的数控机床控制系统。
为了促进平板电脑在工业控制领域的推广和应用，作者通过本书将这些关键技术介绍给读者，与读者共同探讨相关技术，促进其广泛应用。相关的研究和开发经验也可以用于其他自动控制、数据采集和处理设备，例如：智能家电、医疗仪器、科学试验仪器、服务机器人、教学实验设备和物联网终端等。
本书的主要内容如下：
第1章为概述，简要介绍平板电脑在工业自动化领域的应用前景、数控系统工作原理、平板电脑结构、操作系统和编程语言。
第2章介绍了数控系统及其控制软件的整体结构。
第3章介绍了基于平板电脑的数控系统硬件平台结构，以及外部设备现场总线FED和通信控制。
第4章概要介绍了Java编程语言，以及编写数控系统控制软件的Java语法要点。
第5章概要介绍了Android操作系统，以及作为数控系统实时操作系统的可行性。
第6章介绍了数控系统软件的控制原理、实现方法、程序和数据结构的设计流程和程序示例。
第7章介绍了本书编程示例使用的数据结构和参数定义。
附录A为ISO6983数控编程指令国际标准。
附录B为本书编程示例使用的自定义G指令代码。
本书是一本介绍平板电脑数控系统开发方法的书，同时也适用于学习数控系统软件原理、编程方法，以及工业自动化系统开发技术。它包括功能模块的划分、接口、数据流、Andriod操作系统、Java编程语言、以太网通信和现场总线技术等。读者通过本书学习，掌握了数控系统软件编程方法之后，对使用其他编程语言（例如C语言）编写数控系统软件或者开发其他类似的工业自动化设备控制系统也会有很大帮助。
