Industry 4.0 brings up new types of use cases, whereby mobile use cases play a significant role. These use cases have stringent requirements on both automation and communication systems that cannot be achieved with recent shop floor technologies. Therefore, novel technologies such as IEEE time-sensitive networking (TSN) and Open Platform Communications Unified Architecture (OPC UA) are being introduced. In addition, for the realization of mobile use cases, wireline technologies cannot be used and have to be replaced by wireless connections, which have to meet the high demands of the industrial landscape. Here, 5th generation wireless communication system (5G) is seen as a promising candidate. Especially encouraging and similarly challenging is the cooperative work of mobile robots, where particularly high demands on time synchronization arise. Therefore, this paper introduces a concept for the integration of TSN time synchronization (IEEE 802.1AS) conform with 5G to fulfill the requirements of these use cases. Furthermore, the paper describes a testbed for discrete manufacturing, consisting pre-dominantly of industrial equipment, in order to evaluate the presented approach.

将 5G 与 TSN 集成作为高度灵活的未来工业自动化的先决条件：基于 IEEE 802.1AS 的时间同步

工业 4.0 带来了新的用例类型，其中移动用例发挥了重要作用。这些用例对自动化和通信系统都有严格的要求，而最近的车间技术无法实现这些要求。因此，正在引入 IEEE 时间敏感网络 (TSN) 和开放平台通信统一架构 (OPC UA) 等新技术。此外，对于移动用例的实现，有线技术无法使用，必须被无线连接取代，这必须满足工业环境的高要求。在这里，第 5 代无线通信系统 (5G) 被视为有希望的候选者。特别令人鼓舞和同样具有挑战性的是移动机器人的协作工作，其中对时间同步的要求特别高。因此，本文引入了符合 5G 的 TSN 时间同步 (IEEE 802.1AS) 集成概念，以满足这些用例的要求。此外，本文描述了一个主要由工业设备组成的离散制造测试平台，以评估所提出的方法。
