标准摘要
[中文适用范围]: 本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。该网络规范提供了一个标准化协议框架,为各种工业设备提供了一个简单、低成本、节能且高速的网络。为了满足工厂和大型厂房的服务需求,该网络规范旨在使设备能够在无需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。除了高传输速率外,还提供了针对多媒体数据(例如视频)的服务质量 (QoS)。本国际标准中提到的设备是指在工厂和自动化装配线等工业现场使用的设备。此类设备包括 PLC(可编程逻辑控制器)、CNC(计算机数控系统)和制造机器人。然而,除了这些常规设备之外,本国际标准中提到的设备还包括工人在工作时可能携带和使用的个人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 24771:2014 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 help of any infrastructure and 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 24771:2014 refer to equipment that is and can be used in industrial sites such as factories and automated assembly lines. Such devices include PLC (Programmable Logic Controller), and CNC (Computerized Numerical Controller) and manufacturing robots. However, beyond such conventional devices, devices mentioned in this International Standard include personal IT devices that workers may carry and use while working, including cellular phones, personal industrial digital assistants (PDA), and laptop PCs.
