标准摘要
[中文适用范围]： 该国际标准定义了物理层（PHY）和数据链路层的协议，以便在工厂等工业现场的设备之间构建可靠、高速的数据传输网络。 该网络规范提供了标准化协议，为各种工业设备提供框架，在它们之间建立简单、低成本、节能、高速的网络。 为了满足工厂和大型工厂的服务需求，该网络规范旨在使设备能够在不借助任何基础设施的情况下自行建立网络，并可靠地交换各种数据，包括实时音频和视频数据，它们之间。 除了高传输速率之外，还提供多媒体数据（例如视频）的服务质量（QoS）。 本国际标准所称设备是指可用于工厂、自动化装配线等工业现场的设备。 设备包括PLC（可编程逻辑控制器）、CNC（计算机数字控制器）和制造机器人。 然而，除了这些传统设备之外，本文档中提到的设备还包括工作人员在工作时可以携带和使用的个人IT设备，包括蜂窝电话、个人工业数字助理(PDA)和笔记本电脑。 [外文原描述]： ISO/IEC 24771:2009 defines a protocol for the physical layer (PHY) and the data link layer in order to construct a reliable and high-speed data transmission network between devices on industrial sites such as factories and plants. This network specification provides a standardized protocol to provide a framework for various industrial devices to establish a simple, low-cost, energy-efficient, and high-speed network between them. In order to fulfil the service requirements of the factories and large plants, this network specification is designed to enable devices to establish a network by themselves without the help of any infrastructure and to reliably exchange various kinds of data, including real-time audio and video data, between them. In addition to high transmission rates, Quality of Service (QoS) for multimedia data - such as video - is also provided. The devices mentioned in ISO/IEC 24771:2009 refer to equipment that can be used on industrial sites such as factories and automated assembly lines. Devices include PLC (Programmable Logic Controller), and CNC (Computerized Numerical Controller) and manufacturing robots. However, beyond such conventional devices, devices mentioned in this document include personal IT devices that workers may carry and use while working, including cellular phones, personal industrial digital assistants (PDA), and laptop PCs.
