SBC - Edge Computing: 6 Uses Cases for Industrial IoT
Edge computing as holding a promise to no less than “dramatically” improve data processing for mission-critical applications and accelerate the adoption of Industry 4.0. The SBC-Edge Computing Platform, based on single-board computer and single-board edge clusters, provide an opportunity to extend the cloud computing paradigm to the edge where a SBC or micro cloud cluster exists between the data-center and the data source at the edge, which can significantly reduce the decision-making latency, save bandwidth resources, and to some extent, protect and privacy.
The Challenge for Cloud Computing
In traditional cloud computing models, data needs to be transmitted over long distances to cloud service provider data centers for processing and analysis. This can result in latency and network congestion issues, which may affect application performance and efficiency. Additionally, transmitting large amounts of data can produce high costs.
What is Edge Computing
Edge computing is the deployment of computing and storage resources near the edge or source of data generation instead of sending all data to a centralized data center or cloud. By bringing computing resources and data storage closer to end devices and users, edge computing can avoid the latency and cost issues with data transmission.
How Does Edge Computing Work?
Here is an example of how edge computing works:
Let's say you are using a smart thermostat in your home. Instead of sending temperature data to a cloud server for processing, the data is processed locally on the thermostat. The thermostat can then use this data to make adjustments to the temperature in your home in real-time.
To enable edge computing, specialized hardware, such as edge servers, edge routers, and edge gateways are required. These devices have enough processing power and memory to handle data processing tasks quickly and efficiently.
Single-Board Computers (SBCs) vs Commodity Computers for Edge Platforms
Edge platforms typically utilize commodity computers, which can be a significant source of energy consumption. These types of computers use approximately 200 W/h when being used, emitting around 525 kg of CO2 per year. Even in standby mode, power consumption remains relatively high. Data centers utilizing commodity computers consume roughly 1% of the world's electricity usage, which is considered a high percentage. In an effort to reduce energy consumption, Single-board Computers (SBCs) are becoming a popular replacement option for commodity computers. Because SBCs are smaller, less expensive, and consume significantly less energy - approximately 2.7 W in an idle state and 6.4 W in full load.
Single-Board Computers (SBCs) used as Egde Device
In edge computing, SBCs are often used as computing devices for edge nodes to process and analyze data in real-time, and can be used for tasks such as image processing, machine learning, and data analytics. Examples of SBCs include Raspberry Pi, Arduino, BeagleBone and LattePanda. In addition, data privacy is ensured by edge computing since data are being processed locally instead of at the cloud. Yet, with data becoming a higher liability and powerful single board computers (SBC) decreasing in cost, the best solution is often to bring at least some processing back to the local network.
Edge Computing is Essential for Industrial IoT (IIOT)
The term IoT, Internet of Things, is often used to refer to ubiquitous, consumer-oriented IoT products. The Industrial Internet of Things (IIoT) , on the other hand, stands for Industrial Internet of Things, and is a subset of the larger IoT, focusing on the specialized requirements of industrial applications such as manufacturing, oil and gas, and utilities.
IIoT requires both cloud-based data centers and edge processing to function efficiently. While cloud-based resources offer mass storage, processing power, and security, they can also experience latency issues and increased exposure to hackers. To combat these issues, processing and analytics can be performed at the edge with the help of single-board computers (SBCs).

- Smart Manufacturing with SBC-edge Computing for Deep Learning
The use of smart manufacturing in the IIoT has several advantages. New industrialists are adopting IIoT solutions to enhance the productivity and profitability of their industries. The integration of DL methods in smart industries can upgrade the smart manufacturing process into a highly optimized environment by information processing through its multi-layer architecture. Deep Learning(DL) inference and training require substantial computation resources to run quickly. Edge computing, where a fine mesh of compute nodes are placed close to end devices, is a viable way to meet the high computation and low-latency requirements of deep learning on edge devices and also provides additional benefits in terms of privacy, bandwidth efficiency, and scalability.
Use Case Examples for IIoT Edge Computing with SBC-edge clusters (SBC-EC)
- Use Case: Parking Application based on SBC-edge clusters (SBC-EC)
Due to SBC’s small form factor and low costs, SBC based edge clusters can be easily and cost effectively deployed on a site. The sensors data can be relayed to the SBC-edge clusters (SBC-EC) for local processing instead of the distantly located data-center, therefore reducing the need for massive network communication.
The SBC-EC’s ecosystem leverages the use of light weight cloud computing technologies suitable for resource constraint SBC devices. The framework utilizes Docker based containers, Containers are designed to be lightweight having a small foot print in comparison to the traditional virtual machines (VM). Much of the operating system functions such as file system, memory address space and networking can be virtualized in a container. The small size of containers as opposed to a VM makes it easier to copy and move the container images between devices.

The main objective of this application is to log data collected from parking sensors, process the data locally in the SBC-EC (total occupation time of parking bays) and send updates to the cloud service.
The combination of SBC and edge computing provides a powerful platform for Industrial IoT. SBCs offer high performance and reliability, making them suitable for edge computing. They can also collaborate with the cloud for more flexible and efficient IoT applications. Using SBCs as edge computing platforms in industrial IoT deep learning enables real-time data processing and analysis, improving production efficiency, quality control, and predictive maintenance. However, challenges remain in selecting the appropriate SBC platform based on factors such as application requirements, reliability, budget, software support, and community ecosystems. Despite these challenges, the combination of SBCs and edge computing has significant potential in industrial IoT deep learning.
