Phoenix Contact, Weidmüller, Reichle & De-Massari (R&M), Fluke Networks, and Telegartner partner to create SPE System Alliance
菲尼克斯電氣、魏德米勒、R&M、福祿克網(wǎng)絡(luò)、德力格能等成立單對以太網(wǎng)系統(tǒng)聯(lián)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.

隨著單對以太網(wǎng)（SPE）技術(shù)的發(fā)展，菲尼克斯電氣、魏德米勒、R&M、福祿克網(wǎng)絡(luò), 以及德力格能之間的技術(shù)合作不斷加強(qiáng)，并成立了SPE系統(tǒng)聯(lián)盟。該聯(lián)盟將來自不同行業(yè)和應(yīng)用領(lǐng)域的領(lǐng)先技術(shù)公司聚集在一起，整合各自的SPE專業(yè)知識并針對性地開展交流。該聯(lián)盟的成員以追求推動SPE在工業(yè)物聯(lián)網(wǎng)（IIoT）以及相關(guān)領(lǐng)域的進(jìn)一步發(fā)展為目標(biāo)。目前，包括德特威勒、東土科技、微芯科技、羅森伯格、西克、威力工業(yè)網(wǎng)絡(luò)、Draka/Prysmian集團(tuán)和University 4 Industry等公司也正式加入該聯(lián)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.

該聯(lián)盟旨在協(xié)作解決SPE拓展到工業(yè)物聯(lián)網(wǎng)領(lǐng)域所面臨的技術(shù)挑戰(zhàn)。這些公司的目標(biāo)是加速他們在SPE技術(shù)方面的技術(shù)專長，并使其在產(chǎn)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.

根據(jù)跨行業(yè)、跨領(lǐng)域的交互平臺定位，未來所有的SPE生態(tài)系統(tǒng)公司將融為一體。但重點不在諸如連接技術(shù)之類的各個方面，而是將仍面臨各種問題和挑戰(zhàn)的不同市場參與者，通過SPE連接到一起。建立起相關(guān)的互連規(guī)則并使其更為自由的連接。目前的聯(lián)盟成員在第一階段已經(jīng)開展緊密合作，配合領(lǐng)域涉及連接技術(shù)、標(biāo)準(zhǔn)的制定、SPE案例應(yīng)用報告，甚至包含電纜解決方案等等。
 
Thanks to its lineup, the SPE System Alliance already covers a range of applications and fields of application:

得益于眾多業(yè)界公司的加入，SPE系統(tǒng)聯(lián)盟已經(jīng)覆蓋了廣泛的應(yīng)用和應(yīng)用領(lǐng)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.

在當(dāng)今汽車業(yè)高速發(fā)展的時代，越來越多車輛搭載車載以太網(wǎng)系統(tǒng)。通過控制設(shè)備和傳感器的互連，實現(xiàn)輔助系統(tǒng)領(lǐng)域的進(jìn)一步創(chuàng)新，例如LiDAR、高清顯示器、自動駕駛、4K攝像頭和信息娛樂系統(tǒng)的高速傳輸。

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.

汽車以太網(wǎng)的發(fā)展推動兩個全新的IEEE標(biāo)準(zhǔn)的建立：100BASE-T1（基于BroadR-Reach技術(shù)的100 Mbps）和1000BASE-T1（1 Gbps）。根據(jù)對整個通道的要求定義了連接器和電纜的極限值以及相關(guān)的測量方法。合作伙伴羅森伯格在汽車連接器設(shè)計、信號完整性以及電池兼容測試的兩個標(biāo)準(zhǔn)委員會的標(biāo)準(zhǔn)化工作中發(fā)揮了領(lǐng)導(dǎo)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.

物聯(lián)網(wǎng)使智能建筑和工廠更容易、更經(jīng)濟(jì)地成為現(xiàn)實。通過該IP協(xié)議，LED燈、開關(guān)、傳感器、恒溫器、機(jī)器控制系統(tǒng)以及百葉窗的電機(jī)等通過本地數(shù)據(jù)網(wǎng)絡(luò)和云連接到建筑管理系統(tǒng)。不再需要專用的現(xiàn)場總線系統(tǒng)，這意味無需網(wǎng)關(guān)、復(fù)雜的接口和不同的協(xié)議等等。借助數(shù)字化天花板（Digital Ceiling）的框架，智能樓宇控制系統(tǒng)就可以通過IP實現(xiàn)無縫連接。這簡化了安裝、維護(hù)和網(wǎng)絡(luò)運維。在大多數(shù)情況下，智能建筑不需要高速率傳輸，但需要高的連接密度。SPE被認(rèn)為是數(shù)字化天花板的理想補充。SPE可以輕松擴(kuò)展現(xiàn)有的布線基礎(chǔ)設(shè)施，以實現(xiàn)更高的端口密度。R＆M和德力格能提供了數(shù)字化天花板解決方案，并且可以展示SPE在此類系統(tǒng)中的實施。

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提供從現(xiàn)場層到企業(yè)層的一致IP通信，因此也可以提供從傳感器到云端的一致IP通信。標(biāo)準(zhǔn)化的引腳連接器模式構(gòu)成了各種組件和設(shè)備無障礙聯(lián)網(wǎng)的基礎(chǔ)。菲尼克斯電氣、魏德米勒、R＆M、羅森伯格和德力格能按照符合IEC 63171-2（IP20）和63171-5（IP67）的標(biāo)準(zhǔn)且完全兼容的接口開發(fā)緊湊型設(shè)備和電纜連接器。引腳連接器模式可以集成到所有傳統(tǒng)和標(biāo)準(zhǔn)連接器（M8/M12）中，并且由于緊湊和較小的空間要求，因此可以實現(xiàn)高效且面向未來的布線。

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.

現(xiàn)在除了傳統(tǒng)自動化技術(shù)中的應(yīng)用外，傳感器正越來越多地作為智能數(shù)據(jù)模塊通過以太網(wǎng)集成到工業(yè)物聯(lián)網(wǎng)應(yīng)用中。搭載SPE技術(shù)實現(xiàn)連接的小型化，更小及更緊湊的傳感器也能連接到以太網(wǎng)。
 
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.

通過將SPE與數(shù)據(jù)線上的電源組合在一起，可以帶來另一個優(yōu)勢。這意味著不再需要與電源的其他插頭連接。而且，使用SPE作為標(biāo)準(zhǔn)接口允許設(shè)備制造商以更少的版本提供優(yōu)化的設(shè)備范圍。機(jī)器或系統(tǒng)中的傳感器可以更容易地布線，減少了用戶的安裝工作。
 
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應(yīng)用領(lǐng)域中，傳輸信道是由各種電纜和連接器組成。雖然在系統(tǒng)標(biāo)準(zhǔn)（例如ISO/IEC 11801系列標(biāo)準(zhǔn)）中通過傳輸參數(shù)（例如帶寬、衰減、回波損耗和防護(hù)尺寸）指定了傳輸通道，但是必須根據(jù)各自的通道量身定制連接器和電纜 。
 
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委員會正在積極推進(jìn)這項工作，固定路由帶寬為20 MHz的線纜，適用于10BaseT1的信號傳輸，帶寬為600 MHz的電纜適用于100BaseT1和1000BeT1的傳輸（IEC 61156-11系列標(biāo)準(zhǔn)及關(guān)聯(lián)標(biāo)準(zhǔn)）。

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的優(yōu)勢實現(xiàn)了信號和電源同步傳輸，例如從開關(guān)到傳感器。在建筑布線領(lǐng)域被稱為PoE，在這里稱作單對電纜（PoDL，power over data line）?；跈M截面和線纜長度，傳輸?shù)碾娔芸蛇_(dá)約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.

工業(yè)和建筑領(lǐng)域中在不同環(huán)境條件對機(jī)械、耐腐蝕、耐熱、防火及電磁電阻方面有有這不同的要求，聯(lián)盟成員德特威勒和Draka/Prysmian集團(tuán)共享了他們豐富經(jīng)驗。
 
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.

在工業(yè)物聯(lián)網(wǎng)的搭建中，以太網(wǎng)尤其是SPE起著核心作用。不過在引進(jìn)此類技術(shù)時，人們往往忽略對員工進(jìn)行進(jìn)一步培訓(xùn)。University 4 Industry在線學(xué)習(xí)平臺幫助開展工業(yè)物聯(lián)網(wǎng)相關(guān)領(lǐng)域的培訓(xùn)，比如關(guān)于以太網(wǎng)APL主題。
