Multi-screen Display Control for Industrial PC: Unlocking the "Golden Rules" of Cross-screen Synchronization and Split-screen Display
In the welding workshop of a new energy vehicle factory, operator Xiao Wang is staring at three screens in front of him: the left screen displays the real-time welding current curve, the middle screen shows the equipment's operational status, and the right screen scrolls through quality inspection data. This scenario of "multi-functionality on a single screen" is a microcosm of how industrial PC multi-screen display technology empowers smart manufacturing. However, many enterprises still grapple with issues such as: How can cross-screen synchronization be achieved for devices with different protocols? How can split-screen displays be both efficient and stable? How can multi-screen management avoid becoming an amplifier of "data silos"? This article will delve into the core technological paths of multi-screen display and provide practical solutions.
There are dozens of industrial field device protocols (such as Modbus RTU, Profinet, BACnet), while displays typically only support standard protocols like HDMI and DP. A photovoltaic enterprise once attempted to project inverter data onto a monitoring large screen but faced a three-month project delay due to incompatibility between the device's DL/T 645 protocol and the display's HDMI interface. More challenging is that some older devices even use proprietary protocols, further exacerbating integration difficulties.
In semiconductor packaging production lines, the motion trajectories of robotic arms, visual inspection results, and environmental temperature and humidity data need to be displayed synchronously on the same screen. A delay exceeding 50ms can lead to production accidents. A chip manufacturer once suffered a direct loss of over RMB 2 million due to asynchronous multi-screen display, causing misalignment between the robotic arm and visual system actions.
A chemical enterprise's central control room deployed eight screens displaying parameters such as reaction kettle temperature, pressure, and flow rate. However, operators had to frequently shift their gaze, leading to a 15% increase in misoperation rates. More seriously, the data sources for different screens were scattered across multiple systems, lacking a unified management platform, resulting in inefficient troubleshooting.
When addressing multi-screen display challenges, the USR-EG628 industrial PC stands out as a "Swiss Army knife" for enterprise digital transformation with its three core capabilities: "protocol fusion, timing calibration, and intelligent management."
The USR-EG628 is equipped with over 100 industrial protocol parsing engines, supporting real-time conversion of protocols such as Modbus RTU/TCP, OPC UA, BACnet, and DL/T 645. Take a smart grid project as an example: its distribution terminals used the IEC 61850 protocol, electricity meters used the DL/T 645 protocol, and environmental monitoring equipment was based on the Modbus protocol. The USR-EG628 converted all device data into MQTT format through its protocol conversion engine, enabling three-screen synchronized display (current curve, equipment status, environmental parameters). The project integration cycle was shortened from six months to two months.
The USR-EG628 is equipped with a hardware-level timestamp engine that can precisely timestamp each data point (accuracy ±10μs). In a semiconductor packaging production line, its robotic arm control, visual inspection, and environmental monitoring systems achieved timing synchronization through the USR-EG628, with display delays controlled within 20ms and misoperation rates reduced to 0.3%. More critically, this technology does not require modifications to existing equipment; it only requires deploying the USR-EG628 at the data acquisition layer.
The WukongEdge edge management platform should be "accompanying" or "associated", here translated as "associated") with the USR-EG628 supports centralized configuration and remote operation and maintenance of multi-screen display strategies. A chemical enterprise utilized this platform to:
Unified Management: Centrally configure the display content of eight screens (reaction kettle parameters, safety warnings, energy consumption statistics), allowing operators to grasp the overall situation without switching interfaces;
Intelligent Alerts: Automatically trigger audible and visual alarms when data displayed on a screen is abnormal and push notifications to relevant personnel's mobile phones;
Historical Traceability: Save all screen display records, supporting multi-dimensional queries by time, device, and parameter, improving troubleshooting efficiency by 70%.
| Requirement Dimension | Technical Indicators | Implementation Method |
| Protocol Compatibility | Modbus RTU, OPC UA, HDMI/DP | USR-EG628 Protocol Engine |
| Timing Synchronization | ≤ 50ms Delay | Hardware Timestamp Engine |
| Display Strategy | Three-screen asynchronous display + partial synchronization | WukongEdge Configuration |
| Scalability | Support for future new devices | Open API Interface |
The USR-EG628 offers multiple hardware configurations, allowing enterprises to choose flexibly based on their needs:
Basic Version: 2 Gigabit Ethernet ports + 4 serial ports, supporting 2 HDMI/DP outputs, suitable for small to medium-sized production lines;
Flagship Version: 4 Gigabit Ethernet ports + 8 serial ports, supporting 4 HDMI/DP outputs, suitable for large monitoring centers;
Wireless Version: Built-in 4G/WiFi module, supporting remote data acquisition and display, suitable for distributed scenarios.
A photovoltaic enterprise selected the flagship USR-EG628, connecting its monitoring large screen through four HDMI outputs while utilizing eight serial ports to collect data from inverters, electricity meters, and environmental monitoring equipment, achieving centralized management with "one machine, multiple screens."
The USR-EG628 provides a visual configuration tool that supports drag-and-drop interface design:
Protocol Configuration: Select the device protocol (e.g., Modbus RTU) and fill in parameters such as device IP, port, and register address;
Data Mapping: Map device data to display parameters (e.g., map the value of register 40001 to the Y-axis of the "current curve");
Display Strategy: Configure multi-screen display rules (e.g., screen 1 displays the current curve, screen 2 displays equipment status, screen 3 displays quality data);
Timing Calibration: Enable the hardware timestamp function and set synchronization accuracy (e.g., ±20ms).
An electronic component manufacturer completed the configuration of three screens in just two hours using this tool, improving efficiency by 90% compared to traditional programming methods.
Multi-screen display testing should focus on:
Protocol Compatibility: Use tools such as Modbus Poll and OPC UA Expert to simulate devices and verify data acquisition accuracy;
Timing Synchronization: Capture screen display content with a high-speed camera and analyze the time differences between different screens;
Long-term Stability: Run continuously for over 72 hours to check for issues such as memory leaks and task blocking.
A machinery manufacturing enterprise discovered through testing that its original solution experienced screen lag after 24 hours of operation, while the USR-EG628 remained stable after 168 hours of continuous operation, leading to the decision to replace the original equipment.
With the development of AIoT technology, multi-screen display is presenting two major trends:
Low-code Development: The next-generation USR-EG628 will support Blockly programming, allowing developers to complete complex display logic development without writing code;
Intelligence: Integrate lightweight AI models to enable screens with autonomous decision-making capabilities. For example, when the welding current is abnormal, the screen not only displays an alarm message but also automatically adjusts the welding parameters.
