Introduction: Why Industrial Edge Computing?

In the wave of the Industrial Internet of Things (IIoT), uploading device data to the cloud has become essential for remote monitoring, intelligent analysis and predictive maintenance. However, as device numbers explode and real-time requirements tighten, the pure "upload everything to the cloud" model exposes clear drawbacks:

• High latency: Round trips from device to cloud can take seconds or more — far too slow for millisecond-level real-time control on the factory floor.

• High bandwidth cost: Massive fleets continuously uploading all raw data strain network bandwidth and cloud storage budgets.

• Security & privacy: Uploading all sensitive industrial data to the cloud creates risk of leakage and theft.

• Network dependency: If the network drops, devices lose touch with the cloud and on-site control can collapse.

The core idea of industrial edge computing: keep the data-processing "brain" in the cloud, and extend the "nerve endings" to the device site. Edge computing handles fast response, local preprocessing and caching; cloud computing handles global analysis, model training and long-term storage. The two work together to deliver an efficient, intelligent, reliable IIoT system.

Who Needs It: Solving Real-World Pain Points

Industrial edge computing solutions serve four core user groups:

Product Line: SoM, Edge Gateways and SBCs

 SoM (Core Board): The Computing Core of Edge Nodes

The SoM is the "brain" of an edge computing node, integrating processor, memory, storage and power management. EBYTE offers several ARM SoM options for different performance needs:

Edge Collection Gateways: Out-of-the-Box Edge Nodes

Beyond ARM SoMs, EBYTE offers dedicated edge gateway products for rapid deployment:

SBC (Single-Board Computer): Rapid Prototyping & Development

An SBC is a complete computer board integrating CPU, memory, storage and rich interfaces; it can run an OS directly for rapid prototyping:

Collaborative Architecture & Data Flow

Uplink (Device → Edge → Cloud)

[Field devices] --(RS485/Modbus)--> [ARM core-board edge gateway] --(MQTT/WiFi/4G)--> [Cloud platform]

1. Device data collection: The edge gateway polls field devices over serial (RS485/RS232) or Ethernet using Modbus RTU/TCP to fetch raw data (temperature, current, etc.).

2. Edge preprocessing: The gateway cleans, filters and formats raw data, then applies preset rules (e.g. "temperature > 80℃" or "change > 10%") to upload only key or changed data.

3. Packaging & upload: The gateway packs preprocessed data as JSON and uploads it via MQTT (or HTTP/CoAP). Each packet includes device ID, timestamp, value and quality flag.

4. Cloud storage & analysis: The cloud stores data in a time-series DB (e.g. InfluxDB) or relational DB and triggers stream processing for real-time analysis.

Downlink (Cloud → Edge → Device)

1. Cloud command dispatch: Users send control commands via the cloud UI or API ("start motor", "set temperature threshold").

2. Gateway reception: The gateway receives commands in real time via MQTT subscription.

3. Local execution: The gateway parses commands and controls field devices via Modbus or GPIO.

4. Result feedback: The device reports state changes back through the gateway to the cloud, closing the loop.

Edge Standalone Mode (Offline)

When the network drops, the edge gateway enters standalone mode:

• Local data buffering: Collected data is cached on local eMMC storage or an SD card.

• Local rule execution: The gateway keeps running preset local control logic (PID control, threshold alarms) to keep field devices operating.

• Sync on recovery: Once the network returns, the gateway automatically uploads buffered data in timestamp order and syncs the latest cloud configuration.

Application Scenarios

Smart Factory: Predictive Maintenance

Architecture: Field PLC + sensors → E870-G1 (edge gateway) → Alibaba Cloud IoT platform
Workflow:

1. The E870-G1 collects motor vibration, temperature and current data via Modbus RTU.

2. The gateway runs a local rule engine — when vibration exceeds the threshold it immediately triggers a local DO alarm.

3. It uploads preprocessed feature data (vibration amplitude, peak frequency) to the cloud.

4. A cloud AI model (trained on historical data) analyzes features, predicts remaining useful life and generates maintenance work orders.

5. The cloud pushes updated AI models back to the gateway to improve local prediction accuracy.

Smart Agriculture: Remote Irrigation & Environment Monitoring

Architecture: Soil moisture sensors + weather station → E870-D0 (4G edge gateway) → cloud platform
Workflow:

1. The E870-D0 periodically collects sensor data.

2. The gateway executes irrigation strategy locally — if soil moisture is below threshold, it controls the solenoid valve via local DO to start irrigation.

3. It packages humidity, temperature and light data and uploads via 4G.

4. The cloud aggregates all farm data, generates irrigation logs and crop reports, and lets users adjust thresholds remotely.

5. When the signal is weak, the gateway buffers data and batch-uploads once the signal recovers.

Smart Building: Energy Management & Saving Control

Architecture: Electric meters + water meters + HVAC control → ECK40-E (high-performance ARM edge platform) → cloud energy management system
Workflow:

1. The ECK40-E collects smart meter data over RS485.

2. The edge platform runs AI energy-saving algorithms, optimizing HVAC and lighting strategies based on occupancy density, outdoor temperature and historical usage.

3. It aggregates second-level energy data into minute-level summaries and uploads to the cloud.

4. The cloud performs global analysis, identifies energy waste, generates optimization suggestions and pushes updated strategies to the edge.

5. The edge platform drives a local large display via HDMI or MIPI to show energy data and alarms in real time.
