隨著過去僅存在於傳統數據中心或雲端的數據與分析轉移至邊緣，這意味著工業應用正從自動化邁向自主化。但為什麼只有少數工業電腦製造商提供邊緣 AI 平台？這是因為在將具備 AI 的工業電腦部署到現場時存在許多挑戰。

將 AI 整合至工業電腦，就像賦予其人類大腦的學習與推理能力，但不會受到偏見、疲勞或情緒的影響。這種整合能夠提供智慧，進一步提升效率、準確性和生產力。

當您在已有緊湊且散熱條件不佳的嵌入式外殼中加入 GPU 卡或顯示卡時，這會破壞系統的散熱、供電及安裝平衡。

因此，工業電腦的設計必須非常謹慎，確保其 CPU/GPU/元件散熱、電路板佈局、支架機構、干擾隔離，以及外殼結構能協調無縫地運作，以在各種環境條件下持續提供 24/7 的最佳系統效能。

與人類身體相似，邊緣電腦會受到環境因素的影響，例如溫度波動/極端溫度、灰塵、液體、濕氣和鹽分等。而供電接受度就像食物來源，是維持各種操作的關鍵。

因此，工業電腦的設計必須非常謹慎，確保其 CPU/GPU/元件散熱、電路板佈局、支架機構、干擾隔離，以及外殼結構能協調無縫地運作，以在各種環境條件下持續提供 24/7 的最佳系統效能。

當人體過熱時，會散熱來調節體溫，工業電腦也是如此。一個設計良好且高效的散熱系統對工業電腦的壽命、穩定性和效能至關重要。除了溫度，震動/衝擊會影響安裝，而灰塵、液體和濕氣滲入時則可能影響內部元件。

具備寬範圍 DC 輸入接受度對系統的操作和部署可行性至關重要。寬範圍 DC 輸入降低了系統的電壓特定需求，使其在各種情境下更加兼容和靈活。

當環境因素和供電問題得以解決後，您可以根據需求選擇 GPU 卡來決定您的工業電腦能有多智慧。對於 AI，GPU 卡的整合能夠賦予其學習與推理的能力，而其 TFLOPS（每秒一兆次浮點運算）則是處理能力的指標，範圍從個位數到數百。請記住，處理能力越高，產生的熱量也越大。因此，有各種效能等級的 GPU 卡可供選擇，耗電量從 30W 到 250W 不等，您可以根據需求選擇安裝一張或兩張。

GPU 卡的加入賦予工業電腦 AI 能力，但同時也使本已面臨環境挑戰的系統在散熱、安裝及供電方面更加複雜。作為將 AI 整合至工業電腦的先驅之一，Neousys Technology 提供多種經過現場測試的工業電腦，支援從入門到高階 GPU 卡，以滿足您的部署與應用需求。

Unlike general purpose computers—such as desktops used at homes or in offices, Industrial computers are special breeds of personal computers (PCs) deployed or embedded in an automatic/autonomous system to provide the niche computing power for collecting and analyzing data and enabling control / monitoring of the system as well as M2M and human-machine communications.

The most advanced such systems, with Machine Learning and Artificial Intelligence (AI) capabilities, command high degree of autonomy and require least human intervention in process. Some people see them as the enabler of The 5th Industrial Revolution which marks the paradigm shift from IoT to AIoT.

These industrial computers, or IPCs, could be embedded in the wind turbines situated in a desert or a seashore area exposed to enormous day-night temperature difference and other negative environmental factors. Or, they could be embedded in an outdoor system controlling or monitoring energy/power/sewage/transportation facilities and have to withstand harsh and variable weather conditions.

Some of them could be installed in rolling stock or wayside apparatuses susceptible to extreme shocks and vibrations as well as high voltage and electro-magnetic interference. Some of them have AI capabilities and are deployed for driverless vehicles--including autonomous cars and planes--and have to conquer all the extreme situations on the road or in the air.

Some IPCs are embedded in medical apparatuses that must observe the aseptic and hygiene standards for operating rooms. And some could be used in high-end smart factories like semiconductor fabs where clean rooms are 100 times cleaner than a hospital operating room for protecting silicon wafers from ambient contamination.

Therefore, computers made for industrial purposes must fulfill the following features and satisfy the demands of their applications:

• Industrial computers must be made with higher level of rugged designs than normal PCs to provide reliable and stable operations in their application environments that might contain extreme harsh conditions and require 24/7 ceaseless operations. IPCs usually have a wider operating temperature range, higher capabilities in resisting shocks, vibrations, humidity, dust, salt, acid, voltage, electro-magnetic interference, adverse weather, or any other kind of negative environmental factors depending on their application settings and scenarios.
• Industrial computers not only have to maintain compliance with the standards of their domain computers but also often have to observe the industrial standards or regulations in their vertical markets to fulfill application demands and interoperability with other system components.
• For example, computers used for military or defense purposes usually follow the military standards issued by the U.S. Department of Defense (called "MIL-STD" or "MIL-SPEC") in providing interoperability, SWaP (size, weight and power) optimized and rugged platforms ready for quick deployment with off-the-shelf products.
• Industrial computers must have special I/O designs for connecting to different sensors and devices in their purposed application system. Different applications usually have their own I/O emphases. For example, computers used in factory automation usually require serial ports like RS232/422/485 for supporting Modbus/Fieldbus serial communication protocols, or LAN ports for supporting Ethernet, which are rarely seen in commercial computers. Besides, computers used for controlling digital signage would require greater variety in image input/output ports for displaying high quality images, and expansion slots for boosting graphic processing performance. Richer and more versatile I/O designs would usually increase flexibility and expandability for system deployment and deliver greater economic benefits to customers.

We would like to discuss the prerequisites into two directions, hardware specifications and environmental factors. Let’s start with an industrial computer's specifications.

• What is the main purpose of your application system and how much processing power you would need?
  Check the hardware requirements listed by your software provider for reference.
• Do you need AI processing power?
  With modern complex applications, the need for real-time reactions may require artificial intelligence (AI). Applications such as multiple image recognition, or the ability for a machine to sense, reason, act in response to, or adapt according to the application. The complexity of the application will determine the need for an inference accelerator or GPU.
• How much RAM do you need?
  Random Access Memory plays a critical role in deciding computing speed and the overall system performance. ECC (error-correcting code) memory is another type of RAM, which is often chosen for rugged systems or mission-critical applications but typically has a higher price.
• How much storage do you need?
  For industrial applications, solid state disk (SSD) is more rugged and reliable than the mechanical hard disk drive (HHD), and offers significantly higher throughput, but has a higher price tag per GB of storage. If your system will rely on edge computing rather than uploading most data to the cloud, you will need larger capacity for data storage, HDD will be a more economic choice. Of course, you may like to have both of them and obtain high speed and high capacity at the same time if your budget allows.
• Set out your I/O requirements for device communication
  Communication is vital in embedded computing and it brings connected systems into a harmonious sync to execute tasks. Therefore, it is important to make a list of all the devices and equipment the industrial computer will need to establish links and identify their I/O type. You don’t want to have a computer deployed to your floor which is not able to fetch data from all of your critical devices and have to install a second computer to compensate.
• Specify your SWaP restrictions and choose suitable form factors
  An embedded computer often has to fit in a space facing restrictions in size, weight and power (SWaP), which sometimes run into contradiction with performance demand. Understand your environmental restrictions and choose a computer with form factors that meet your needs.
• Flexibility and expandability
  Your system is expected to be used for years to generate returns on investment, but technologies are always advancing and your system could be left behind. To protect your investment and maximize economic benefits, choose an industrial computer with future-proofing designs, so you can upgrade your system and add new features without sacrificing your existing system.
• Budget
  Your budget constraint is always your biggest pain point in planning your project and choosing a perfect computer. All your dreams about computing performance and stunning features have to be measured against your budget ceiling.

When choosing an industrial computer for your application, the "environmental factors" are of utmost importance, because, if the computer cannot operate in the deployed environment, all other specifications are just irrelevant. So understanding the environment your industrial computer will be operating in 24/7 becomes crucial to a successful deployment.

• Temperature range
  Heat is the biggest enemy for electronic components in a computer. Without an efficient thermal dissipation design, it can cause a processor to thermal throttle (reduced operating frequency) resulting in performance degradation; and the effects of long term high temperature operation of electronic components may also significantly reduce their lifespan! Many computers are deployed out in the open and perhaps have to boot under minus zero coldness in the morning and operate under blazing sun in up to 50°C air temperature at noon. Computers deployed to manufacturing facilities often have to face constant extreme heat. So identifying the temperature range in your application setting and make sure that your IPC supplier is able to provide "real" wide temperature support to meet your application needs.
• Note characteristics of location
  Many computers are deployed to a confined space and will need a SWaP optimized design; others could be deployed in vehicles or mobile applications like autonomous mobile robots (AMRs) and will face extreme shocks and vibrations during operation. Find a computer with reinforced capabilities that address the characteristics of your application location.
• Environmental criteria in the vertical industry
  Many vertical markets have their common environmental concerns that IPC applications have to address, such as shock and vibration, humidity, salinity, temperature, and many more, and certain industries have developed their own standards for electrical or electronic equipment. For example, defense applications often follow MIL-STD for ruggedness compliance; railway applications are often required to address the international standards in anti-electromagnetic interference and anti-shock and vibration capabilities; computers used in medical applications should observe water/dust proofing and aseptic standards. If you don’t have clear ideas about specific environmental requirements of your applications, look into industrial certifications for reference and assurance.
