Multi-screen Interaction of Industrial Touch Screen PCs: Unlocking the "Golden Key" to Cross-device Data Synchronization
In the wave of Industry 4.0 and smart city construction, industrial touch screen PCs are evolving from single data display terminals into composite devices that function as both "data hubs" and "intelligent nodes." Their core value lies not only in high-definition display and edge computing capabilities but also in breaking down data silos between devices through multi-screen interaction technology, enabling real-time collaboration across terminals and scenarios.

However, how can seamless data synchronization be achieved among devices of different brands and protocols? How can a stable, efficient, and low-latency multi-screen联动 (linked) ecosystem be constructed? This article will delve into the technical pathways and implementation strategies for cross-device data synchronization, drawing on practical cases involving the USR-SH800 industrial touch screen PC.

Core Challenges of Multi-screen Interaction: From "Information Silos" to "Data Floods"
1.1 Protocol Barriers: The Dilemma of Incompatible Device "Languages"
Industrial sites utilize dozens of protocols, including Modbus, Profibus, and CANopen, while smart cities require compatibility with IoT protocols like MQTT, CoAP, and LoRa. Traditional solutions rely on customized gateways or protocol converters, leading to high deployment costs and poor scalability. For example, an automotive parts factory incurred an additional 300,000 RMB in protocol conversion equipment costs during a production line upgrade due to incompatible device protocols. Each new device addition required reconfiguration, taking up to two weeks.
1.2 Data Floods: The Trade-off Between Real-time Performance and Bandwidth
A single device can generate hundreds of data points per second, with data volumes growing exponentially in multi-screen联动 scenarios. If a "full upload" model is used, cloud load surges, and latency spikes. Conversely, uploading only critical data risks losing important information. A smart energy project once experienced a 15-minute delay in grid dispatch decisions due to data synchronization issues, resulting in direct economic losses exceeding one million RMB.
1.3 Fragmented Scenarios: The Challenge of Adapting to Diverse Needs
Different industries have vastly different multi-screen interaction requirements:
Industrial Manufacturing: Requires cross-screen of production line equipment status, quality inspection data, and process parameters.
Smart Cities: Demand global visualization of traffic flow, environmental monitoring, and emergency command data.
Smart Healthcare: Focuses on real-time synchronization of operating room equipment, patient vital signs, and remote consultation feeds.
Traditional "one-size-fits-all" solutions struggle to meet these differentiated needs, significantly reducing project implementation effectiveness.

USR-SH800's Breakthrough Approach: Four Core Technologies Redefining the Multi-screen Interaction Ecosystem
2.1 Protocol Fusion Engine: "One-click" Interoperability for Hundreds of Protocols
The USR-SH800's built-in WukongEdge edge application platform integrates over 100 industrial protocol libraries, covering mainstream protocols such as Modbus, OPC UA, BACnet, Power 104, and Water SL651. Through its dual engines of "protocol conversion + data standardization," it enables automatic parsing and unified modeling of device data. For example, in a smart park project, the USR-SH800 simultaneously connected:
200 air conditioning units using Modbus;
50 elevator control systems employing OPC UA;
300 LoRa-based environmental sensors.
All devices were integrated and synchronized within two hours, achieving a 90% efficiency improvement over traditional solutions.

2.2 Edge Computing Hierarchical Architecture: Data "Slimming" and Intelligent Processing
The USR-SH800 adopts a three-tier "end-edge-cloud" data processing architecture:
End Layer: Directly collects raw data (e.g., temperature, pressure, current) via sensors.
Edge Layer: Performs local data cleaning (filtering invalid data), feature extraction (e.g., calculating equipment vibration frequency), and anomaly detection (e.g., threshold comparison).
Cloud Layer: Uploads only key metrics (e.g., equipment health scores, process parameter optimization recommendations), reducing data transmission by over 90%.
In a steel plant blast furnace monitoring project, edge computing reduced daily data transmission from 10TB to 1TB, shortened fault response times from five minutes to eight seconds, and prevented a potential blast furnace shutdown.

2.3 Dynamic Configuration and Low-Code Development: From "Code Programming" to "Drag-and-Drop Configuration"
The USR-SH800's built-in Web configuration tool supports drag-and-drop interface design, enabling:
Device icon binding: Dragging temperature sensor icons onto configuration screens automatically links them to real-time data.
Logic rule configuration: Setting联动 conditions through verbal descriptions (e.g., "Activate cooling fans when temperature > 300°C").
Multi-screen division of labor: Main screens display global data, secondary screens show detailed parameters, and floating screens control current devices.
In a 3C product assembly line project, engineers built a digital twin system in just two hours, achieving an 80% efficiency improvement over traditional configuration software. The system reduced line changeover times by 35% and increased overall equipment effectiveness (OEE) by 18%.

2.4 Multi-screen Synchronization Protocol Stack: "Time-Space Compression" with Millisecond-Level Latency
The USR-SH800 employs a triple synchronization protocol stack of "NTP + MQTT + WebSocket":
NTP (Network Time Protocol): Ensures time synchronization errors <1ms across all devices.
MQTT (Lightweight Message Queue): Enables real-time data transmission between devices, reducing bandwidth usage by 60%.
WebSocket: Supports full-duplex communication, ensuring cross-screen operation delays (e.g., dragging, annotations) <20ms.
In a provincial grid dispatch center project, four 4K screens displayed a provincial grid topology map, dynamically adjusting display priorities based on load changes. The project reduced peak-valley grid differences by 18%, increased renewable energy consumption by 12%, and lowered line losses by 12%.

Scenario-based Practices: How USR-SH800 Reshapes Industry Boundaries?
3.1 Smart Manufacturing: The "Nerve Center" of Production Line Digital Twins
In an automotive parts factory, the USR-SH800 built a production line digital twin system:

Secondary Screen: Shows quality inspection data, automatically marking defect locations and triggering alarms.
Mobile End: Engineers access equipment maintenance guides and scan codes for spare parts inventory information.
The solution reduced line changeover times by 35%, increased OEE by 18%, lowered product defect rates from 1.2% to 0.3%, and saved over two million RMB in annual quality costs.

3.2 Smart Energy: The "Intelligent Dispatcher" for Grid Demand Response
In a provincial grid dispatch center, the USR-SH800 enabled optimized energy management:
Multi-screen Integration: Four 4K screens displayed a provincial grid topology map, showing real-time generation, transmission, and consumption data.
Dynamic Configuration: Automatically adjusted display priorities based on load changes, highlighting substation load rates during peak periods.
Edge Computing: Locally analyzed electricity usage data, generating demand response strategies (e.g., adjusting industrial user electricity consumption periods).
The project reduced peak-valley grid differences by 18%, increased renewable energy consumption by 12%, and lowered line losses by 12%.

3.3 Remote Operation and Maintenance: The "Eagle Eye" for Unmanned Wind Farms
In an offshore wind farm, the USR-SH800 established a remote operation and maintenance system:
AR Augmented Display: Overlaid real-time turbine parameters and historical maintenance records via AR glasses.
Voice Interaction: Field personnel queried data using natural language (e.g., "Display temperature curve for Turbine 3's gearbox").
Multi-screen联动: The main screen showed turbine overviews, secondary screens displayed detailed components, and mobile ends pushed alarm notifications.
The solution improved expert-guided on-site maintenance efficiency by 60%, reduced annual on-site visits by 120 times, and lowered operation and maintenance costs by 40%.

Future Trends: From "Multi-screen联动" to "Scenario Intelligence"
With advancements in 5G, digital twins, and large models, the multi-screen interaction capabilities of industrial touch screen PCs are evolving across three dimensions:
