智能制造和數(shù)字化轉(zhuǎn)型，再加上邊緣智能，使制造商能夠提高生產(chǎn)力、減少停機(jī)時(shí)間并提高產(chǎn)品質(zhì)量。這種轉(zhuǎn)型成功的一個(gè)關(guān)鍵因素是智能邊緣計(jì)算解決方案的部署，該解決方案可以通過(guò)提供許多好處來(lái)彌合運(yùn)營(yíng)技術(shù) (OT) 和信息技術(shù) (IT) 世界之間的差距。在本文中，我們將討論制造商需要從 IIoT 趨勢(shì)中受益，以及新一代 IIoT 網(wǎng)關(guān)如何幫助他們獲得 IIoT 的好處，從而改變他們的業(yè)務(wù)。

減少延遲

制造商有望通過(guò)在全球范圍內(nèi)提供定制產(chǎn)品和服務(wù)來(lái)更好地響應(yīng)客戶(hù)需求。此外，對(duì)時(shí)間敏感的應(yīng)用程序需要立即處理設(shè)備數(shù)據(jù)，以便能夠及時(shí)采取糾正措施并促進(jìn)快速?zèng)Q策。邊緣智能可以促進(jìn)現(xiàn)場(chǎng)站點(diǎn)的快速?zèng)Q策，而不是將所有設(shè)備數(shù)據(jù)從邊緣發(fā)送到云端進(jìn)行處理。

獨(dú)立遠(yuǎn)程操作

邊緣計(jì)算平臺(tái)使遠(yuǎn)程位置能夠減少停機(jī)時(shí)間并在中央系統(tǒng)無(wú)法訪問(wèn)時(shí)獨(dú)立運(yùn)行。例如，如果網(wǎng)絡(luò)中斷并且與云系統(tǒng)的連接丟失，現(xiàn)場(chǎng)站點(diǎn)可以使用本地計(jì)算能力來(lái)處理和分析數(shù)據(jù)。當(dāng)連接恢復(fù)時(shí)，處理后的數(shù)據(jù)可以發(fā)送到云端進(jìn)行長(zhǎng)期存儲(chǔ)。

數(shù)據(jù)安全

將敏感的操作數(shù)據(jù)從邊緣發(fā)送到云端會(huì)使數(shù)據(jù)和邊緣設(shè)備面臨風(fēng)險(xiǎn)。需要設(shè)置多個(gè)級(jí)別的安全性，以確保數(shù)據(jù)從邊緣設(shè)備安全地傳輸?shù)皆贫恕?/font>在邊緣處理數(shù)據(jù)有助于防止數(shù)據(jù)泄露并實(shí)現(xiàn)更快的響應(yīng)。

降低數(shù)據(jù)傳輸成本

將大量數(shù)據(jù)從網(wǎng)絡(luò)邊緣傳輸?shù)皆品?wù)器可能非常昂貴。此外，從長(zhǎng)遠(yuǎn)來(lái)看，每天傳輸這些數(shù)據(jù)的成本可能會(huì)導(dǎo)致不可持續(xù)的通信成本。

制造商正在為其工業(yè)自動(dòng)化應(yīng)用程序?qū)ふ覂?yōu)化的計(jì)算解決方案，以智能地處理從傳感器和現(xiàn)場(chǎng)監(jiān)視器接收到的大量數(shù)據(jù)，并僅將關(guān)鍵數(shù)據(jù)或數(shù)據(jù)摘要發(fā)送到云端。緊湊型、堅(jiān)固耐用的基于 Arm 的工業(yè)計(jì)算機(jī)，專(zhuān)為低功耗而設(shè)計(jì)，是這些解決方案的核心，使邊緣計(jì)算更加可靠和更具成本效益。

基于 Arm 的 Linux IIoT 網(wǎng)關(guān)解決方案提供工業(yè)級(jí)安全性、可管理性、性能和可靠性，同時(shí)仍保持可擴(kuò)展性。它們通常結(jié)合下面列出的硬件、操作系統(tǒng)和軟件功能，為 IIoT 應(yīng)用提供優(yōu)化的邊緣計(jì)算解決方案。

壽命：工業(yè)產(chǎn)品的使用期限通常為 10 至 15 年。為了滿(mǎn)足這一要求，基于 Arm 的 CPU 通常具有至少 15 年的使用壽命。此外，Arm 對(duì)長(zhǎng)期支持和獲取其未來(lái)增強(qiáng)功能的承諾，使基于 Arm 的解決方案成為工業(yè)應(yīng)用的理想選擇。

低功耗：低功耗處理是許多行業(yè)的要求，以確保設(shè)備不會(huì)過(guò)熱并造成潛在危險(xiǎn)。無(wú)風(fēng)扇設(shè)備也是，以減輕工業(yè)環(huán)境中灰塵的影響。Arm Cortex-A 處理器針對(duì)性能和電源效率進(jìn)行了高度優(yōu)化。

可擴(kuò)展性：Linux 具有出色的可擴(kuò)展性，能夠在各種平臺(tái)上運(yùn)行。Linux 平臺(tái)的基本功能——命令行工具、配置和代碼——與任何基于 Linux 的設(shè)備兼容。這種靈活性使不同系統(tǒng)之間的升級(jí)和兼容性變得更加容易。

增強(qiáng)的安全性：制造商在從數(shù)字化中獲益的同時(shí)，也面臨著數(shù)據(jù)安全風(fēng)險(xiǎn)和軟件完整性問(wèn)題。可以部署可信平臺(tái)模塊（TPM）來(lái)保證邊緣設(shè)備的物理安全。此外，Arm 的 TrustZone 可用于創(chuàng)建一個(gè)隔離的安全世界，可以增強(qiáng)安全性并保持邊緣計(jì)算解決方案的完整性。

Arm-based Linux IIoT Gateway solutions provide industrial-grade security, manageability, performance, and reliability while still maintaining extensibility. They typically combine the hardware, OS, and software functions listed below to provide an optimized edge-computing solution for IIoT applications.

Longevity: Industrial products are usually in place for 10 to 15 years. To meet this requirement, Arm-based CPUs typically come with a minimum lifespan of 15 years. In addition, Arm’s commitment to long-term support and access to their future enhancements, make Arm- based solutions an ideal choice for industrial applications.

Low Power Consumption: Low-power processing is a requirement in many industries to ensure that the equipment does not overheat and pose a potential hazard. Fanless equipment are also preferred so as to mitigate the effects of dust in industrial environments. Arm Cortex-A processors are highly optimized for performance and power efficiency.

Scalability: Linux is eminently scalable and is able to run on a variety of platforms. The basic functionality of a Linux platform—command line tools, configuration, and code—are compatible with any Linux-based device. This flexibility allows for easier upgrades and compatibility between different systems.

Enhanced Security: While manufacturers are reaping the benefits of digitization, they are also faced with data security risks and software-integrity issues. A Trusted Platform Module (TPM) can be deployed to guarantee the physical security of edge devices. In addition, Arm’s TrustZone can be used to create an isolated secure world, which can enhance security and maintain the integrity of edge-computing solutions.

Ready-to-run IIoT gateways

A new generation of IIoT Gateways that are optimized for industrial applications are revolutionizing the manufacturing landscape. Built around an open Linux-based platform, these IIoT gateways are secure, industrial-grade computing platforms that support multiple communication interfaces and run on low power.
