菲尼克斯电气、魏德米勒、R&M、福禄克网络、德力格能等成立单对以太网系统联盟

The technology partnership between Phoenix Contact, Weidmuller, Reichle & De-Massari (R&M), Fluke Networks, and Telegartner for the Single Pair Ethernet (SPE) has progressed to create the SPE System Alliance. In this group, technology companies from various industries and fields of application have come together to bundle their respective SPE expertise and ensure the target-oriented exchange of this knowledge. The partners in this group are pursuing the goal of driving the development of SPE further forward for the Industrial Internet of Things (IIoT) and may branch out to other areas as well. The System Alliance has now also been joined by Datwyler, Kyland, Microchip Technology, Rosenberger, SICK, ORing, Draka/Prysmian Group, and University 4 Industry.

随着单对以太网（SPE）技术的发展，菲尼克斯电气、魏德米勒、R&M、福禄克网络, 以及德力格能之间的技术合作不断加强，并成立了SPE系统联盟。该联盟将来自不同行业和应用领域的领先技术公司聚集在一起，整合各自的SPE专业知识并针对性地开展交流。该联盟的成员以追求推动SPE在工业物联网（IIoT）以及相关领域的进一步发展为目标。目前，包括德特威勒、东土科技、微芯科技、罗森伯格、西克、威力工业网络、Draka/Prysmian集团和University 4 Industry等公司也正式加入该联盟。
 
The network aims to collaborate on the technological challenges faced when implementing SPE in IIoT applications. The goal of the companies is to accelerate their own development of expertise in SPE technology and to allow it to be implemented in their products.

该联盟旨在协作解决SPE拓展到工业物联网领域所面临的技术挑战。这些公司的目标是加速他们在SPE技术方面的技术专长，并使其在产品中得以部署。

Through this orientation toward a cross-industry and cross-application exchange platform, companies from all future SPE ecosystems are coming together. The focus is not, however, on individual aspects such as connection technology. Instead, the focus is on questions and challenges that continue to exist with many market participants in connection with SPE. Rule exchange formats and collaborative project activities provide the freedom for close cooperation. The members are already working together in the first sub-communities, in the fields of connection technology, standardization, SPE use-case reports, and even for cable solutions, among others.

根据跨行业、跨领域的交互平台定位，未来所有的SPE生态系统公司将融为一体。但重点不在诸如连接技术之类的各个方面，而是将仍面临各种问题和挑战的不同市场参与者，通过SPE连接到一起。建立起相关的互连规则并使其更为自由的连接。目前的联盟成员在第一阶段已经开展紧密合作，配合领域涉及连接技术、标准的制定、SPE案例应用报告，甚至包含电缆解决方案等等。
 
Thanks to its lineup, the SPE System Alliance already covers a range of applications and fields of application:

得益于众多业界公司的加入，SPE系统联盟已经覆盖了广泛的应用和应用领域。

Ethernet systems are being installed increasingly in the vehicle generations of today. Through the networking of control devices and sensors, further innovations in the fields of driver assistance systems such as LiDAR, high-resolution displays, autonomous driving, 4K cameras, and infotainment can be realized.

在当今汽车业高速发展的时代，越来越多车辆搭载车载以太网系统。通过控制设备和传感器的互连，实现辅助系统领域的进一步创新，例如LiDAR、高清显示器、自动驾驶、4K摄像头和信息娱乐系统的高速传输。

The development of the automobile Ethernet has led to the creation of two IEEE standards: 100BASE-T1 (100 Mbps based on BroadR-Reach technology) and 1000BASE-T1 (1 Gbps). Limit values for the connectors and cables and the associated measurement methods were defined from the demands on the overall channel. The partner company Rosenberger played a leading role in the standardization in both standard committees in the fields of automotive connector design, signal integrity, and EMC.

汽车以太网的发展推动两个全新的IEEE标准的建立：100BASE-T1（基于BroadR-Reach技术的100 Mbps）和1000BASE-T1（1 Gbps）。根据对整个通道的要求定义了连接器和电缆的极限值以及相关的测量方法。合作伙伴罗森伯格在汽车连接器设计、信号完整性以及电池兼容测试的两个标准委员会的标准化工作中发挥了领导作用。

The Internet of Things (IoT) allows smart buildings and factories to become a reality more easily and cost-effectively. With this IP protocol, LED lamps, switches, sensors, thermostats, machine control systems, and motors for window blinds are connected via the local data network and the cloud to the building management system. Application-specific fieldbus systems are no longer needed, meaning that gateways, complex interfaces, and different protocols are not necessary either. With the structured ceiling cabling (the Digital Ceiling), intelligent building automation can be combined via IP. This simplifies installation, maintenance, and network management. In most cases, high data rates are not needed, but a high connection density is. SPE is considered an ideal addition for the Digital Ceiling. The existing cabling infrastructure can easily be expanded with SPE for higher port density. Both, R&M and Telegärtner provide Digital Ceiling solutions and can show the implementation of SPE into such a system.

物联网使智能建筑和工厂更容易、更经济地成为现实。通过该IP协议，LED灯、开关、传感器、恒温器、机器控制系统以及百叶窗的电机等通过本地数据网络和云连接到建筑管理系统。不再需要专用的现场总线系统，这意味无需网关、复杂的接口和不同的协议等等。借助数字化天花板（Digital Ceiling）的框架，智能楼宇控制系统就可以通过IP实现无缝连接。这简化了安装、维护和网络运维。在大多数情况下，智能建筑不需要高速率传输，但需要高的连接密度。SPE被认为是数字化天花板的理想补充。SPE可以轻松扩展现有的布线基础设施，以实现更高的端口密度。R＆M和德力格能提供了数字化天花板解决方案，并且可以展示SPE在此类系统中的实施。

SPE provides consistent IP communication from the field level right through to the corporate level, and therefore from the sensor through to the cloud. Standardized pin connector patterns form the basis for the barrier-free networking of a wide range of components and devices. Phoenix Contact, Weidmuller, R&M, Rosenberger, and Telegärtner develop compact device and cable connectors in accordance with the standardized and fully compatible interfaces in accordance with IEC 63171-2 (IP20) and 63171-5 (IP67). The pin connector pattern can be integrated into all conventional and standardized connector versions (M8/M12) and enables efficient and future-proof cabling thanks to the high packing density and low space requirements.

SPE提供从现场层到企业层的一致IP通信，因此也可以提供从传感器到云端的一致IP通信。标准化的引脚连接器模式构成了各种组件和设备无障碍联网的基础。菲尼克斯电气、魏德米勒、R＆M、罗森伯格和德力格能按照符合IEC 63171-2（IP20）和63171-5（IP67）的标准且完全兼容的接口开发紧凑型设备和电缆连接器。引脚连接器模式可以集成到所有传统和标准连接器（M8/M12）中，并且由于紧凑和较小的空间要求，因此可以实现高效且面向未来的布线。

Now,in addition to their use in classic automation technology, sensors are increasingly being integrated as intelligent data suppliers into IIoT applications via Ethernet networks. Due to the miniaturization of the connection technology that has become possible with SPE, smaller and spatially limited sensors can also be connected to Ethernet networks.

现在除了传统自动化技术中的应用外，传感器正越来越多地作为智能数据模块通过以太网集成到工业物联网应用中。搭载SPE技术实现连接的小型化，更小及更紧凑的传感器也能连接到以太网。
 
An additional advantage is yielded by combining SPE with the power supply over the data line. This means that additional plug connections to the voltage supply are no longer needed. Moreover, the use of SPE as the standard interface allows device manufacturers to provide an optimized range of devices with fewer versions. Sensors in a machine or system can be cabled more easily and reduce the installation work for the user.

通过将SPE与数据线上的电源组合在一起，可以带来另一个优势。这意味着不再需要与电源的其他插头连接。而且，使用SPE作为标准接口允许设备制造商以更少的版本提供优化的设备范围。机器或系统中的传感器可以更容易地布线，减少了用户的安装工作。
 
In SPE fields of application, the transmission channels are created from various cables and a varying number of plug connections. While the transmission channels are specified through transmission parameters such as bandwidth, attenuation, return loss, and shielding dimensions in the system standards (e.g., the ISO/IEC 11801 series of standards), the connectors and cables must then be tailored to the respective channel.

在SPE应用领域中，传输信道是由各种电缆和连接器组成。虽然在系统标准（例如ISO/IEC 11801系列标准）中通过传输参数（例如带宽、衰减、回波损耗和防护尺寸）指定了传输通道，但是必须根据各自的通道量身定制连接器和电缆 。
 
The work being performed in the IEC46C committee is taking the lead here. Cables with a 20 MHz bandwidth for fixed routing, connecting cables suitable for the 10BaseT1 channels, and cables with a bandwidth of 600 MHz for 100BaseT1 and 1000BaseT1 are available (IEC 61156-11 series of standards and those following).

IEC46C委员会正在积极推进这项工作，固定路由带宽为20 MHz的线缆，适用于10BaseT1的信号传输，带宽为600 MHz的电缆适用于100BaseT1和1000BeT1的传输（IEC 61156-11系列标准及关联标准）。

Along with the transmission of signals, the advantage lies in the simultaneous transmission of power along the single-pair cable, for example from the switch to the sensor. Known as PoE in the field of building cabling, the single-pair cable is called PoDL (Power over Data Line) here. Coordinated with the cross-sections and channel length, powers of up to approx. 15W can then be transmitted.

SPE的优势实现了信号和电源同步传输，例如从开关到传感器。在建筑布线领域被称为PoE，在这里称作单对电缆（PoDL，power over data line）。基于横截面和线缆长度，传输的电能可达约15W。

The different ambient conditions in industry and in building technology result in requirements on the mechanical, chemical, thermal, fire-related, and even electromagnetic resistance aspects. The system partners contributing their experience in this field are Datwyler and the Draka Prysmian Group.

工业和建筑领域中在不同环境条件对机械、耐腐蚀、耐热、防火及电磁电阻方面有有这不同的要求，联盟成员德特威勒和Draka/Prysmian集团共享了他们丰富经验。
 
Ethernet in general and SPE in particular play a central role in the establishment of the Industrial Internet of Things. Often, however, the need for further training of employees is not considered when introducing such technologies. This is where University 4 Industry helps with online learning content from various areas of IIoT, e.g. on the topic of Ethernet APL.

在工业物联网的搭建中，以太网尤其是SPE起着核心作用。不过在引进此类技术时，人们往往忽略对员工进行进一步培训。University 4 Industry在线学习平台帮助开展工业物联网相关领域的培训，比如关于以太网APL主题。
