In industrial scenarios such as smart manufacturing, energy management, and traffic control, the choice of an operating system directly impacts equipment stability, response speed, and development efficiency. Faced with the three mainstream systems of Windows, Linux, and RTOS, enterprises often find themselves in a dilemma characterized by "difficult technical adaptation, high selection costs, and poor ecosystem compatibility." This article provides an analysis from three dimensions: technical characteristics, scenario requirements, and selection logic. It incorporates practical cases from the USR-EG628 industrial personal computer to offer enterprises actionable system adaptation solutions and guides them to submit inquiries for customized advice.

1. Comparison of Technical Characteristics: Core Capability Maps of the Three Systems

1.1 Windows System: The "Compatibility King" of Industrial Ecosystems

Technical Advantages:
The Windows system, with its mature industrial ecosystem, has become the preferred choice for equipment integration and rapid deployment:
Hardware Compatibility: Supports mainstream industrial protocols (such as Modbus, OPC UA, Profinet) and has a driver library that covers over 90% of industrial equipment. For example, an automotive production line directly runs Siemens TIA Portal software on a Windows system, achieving seamless integration between PLCs and HMIs and reducing debugging time by 50%.
Development Toolchain: Tools like Visual Studio and .NET Framework support low-code development, making it suitable for quickly building industrial apps. A food enterprise used Power Apps to develop a production line quality inspection app, completing the process from requirement to deployment in just three days.
User-Friendliness: The graphical interface lowers the operational threshold, allowing maintenance personnel to operate without professional training. A chemical enterprise used Windows Remote Desktop to monitor equipment across workshops, tripling operational efficiency.
Technical Bottlenecks:
Insufficient Real-Time Performance: As a non-real-time operating system (RTOS) architecture, task scheduling delays can reach 10-100 milliseconds, making it difficult to meet high-precision scenarios such as robot control.
High Resource Consumption: System updates and background services may occupy over 30% of CPU resources, leading to lag on low-configuration industrial computers.
Security Risks: The open ecosystem is vulnerable to virus attacks. A manufacturing enterprise once experienced a production line shutdown for two hours due to unpatched vulnerabilities.
Applicable Scenarios:
Production monitoring, equipment management, data display, and other scenarios with high compatibility requirements but low real-time requirements. For example, a wind farm integrates data from multiple brands of wind turbines using a Windows system to achieve unified monitoring and fault warning.

1.2 Linux System: The "Customization Expert" for Performance and Stability

Technical Advantages:
Linux systems, with their open-source and customizable nature, excel in industrial automation:
Low Resource Consumption: The kernel can be trimmed to retain only necessary modules, making it suitable for embedded devices. For example, the USR-EG628 industrial personal computer, based on the Linux Ubuntu system, occupies only 400MB of memory while stably running edge computing tasks.
High Stability: Without a forced restart mechanism, it supports 7×24-hour continuous operation. A steel enterprise deployed a Linux system and reduced equipment annual failure rates from 2.8% to 0.4%.
Flexible Protocol Support: Achieves multi-protocol compatibility through kernel modules or user-space drivers. A logistics enterprise used a Linux system to simultaneously parse protocols such as Modbus RTU, CANopen, and EtherCAT, reducing intermediate gateway costs.

Technical Bottlenecks:
High Learning Curve: Command-line operations and configuration file management require professional technicians, with a training period of up to two months for small and medium-sized enterprises.
Difficult Driver Adaptation: Minority hardware lacks official drivers, requiring self-development or reliance on community support. An agricultural enterprise delayed a project by one month due to incompatible sensor drivers.
Applicable Scenarios:
Automated production lines, data acquisition, edge computing, and other scenarios with high performance and stability requirements. For example, a photovoltaic power plant uses a Linux system to run AI predictive maintenance algorithms, analyzing inverter data in real-time through local models and achieving a 92% fault warning accuracy rate.

1.3 RTOS System: The "Ultimate Pursuer" of Real-Time Performance

Technical Advantages:
RTOS (Real-Time Operating System) is designed for high-precision control, with core characteristics including:
Deterministic Response: Task scheduling algorithms ensure critical operations are completed within specified times. For example, a semiconductor manufacturing enterprise achieved nanometer-level positioning accuracy in lithography machine motion control using an RTOS system.
Lightweight Design: The kernel code volume is typically less than 100,000 lines, with a startup time of less than one second, making it suitable for resource-constrained scenarios. A medical device manufacturer reduced equipment power consumption by 60% and extended battery life to eight hours after adopting an RTOS.
Task Isolation: Prevents high-priority tasks from being blocked by low-priority tasks through priority division and memory protection. An aerospace enterprise used an RTOS system to achieve aircraft attitude control, ensuring zero delay for critical tasks.
Technical Bottlenecks:
Limited Ecosystem: Fewer development tools and software libraries, with functional expansion relying on vendor support. A robot enterprise was forced to switch to a Linux system due to a lack of visual algorithm libraries.
Compatibility Risks: Hardware drivers require custom development, with high upgrade costs. An automotive electronics manufacturer had to redevelop drivers for each product generation, increasing R&D costs by 20%.
Applicable Scenarios:
Robot control, precision machining, aerospace, and other scenarios with stringent real-time requirements. For example, a robotic arm manufacturer reduced trajectory tracking errors from ±0.5mm to ±0.1mm using an RTOS system, significantly enhancing product competitiveness.

2. Scenario-Driven Selection: Four Core Decision-Making Logics

2.1 Real-Time Requirements: The Critical Point of Millisecond-Level Response

High Real-Time Scenarios (such as robot control, vibration monitoring): Prioritize RTOS systems to ensure tasks are completed on time. For example, a wind farm used an RTOS system to collect gearbox vibration data in real-time, advancing fault prediction time by 72 hours.
Medium Real-Time Scenarios (such as production line interlocking, data acquisition): Linux systems can meet requirements through kernel tuning (such as adjusting scheduling strategies). A packaging machinery factory achieved multi-axis synchronous control with a synchronization error of less than 0.1 milliseconds using a Linux system.
Low Real-Time Scenarios (such as monitoring display, log recording): The compatibility advantages of Windows systems are more prominent. A chemical enterprise integrated data from multiple brands of instruments using a Windows system to achieve visual monitoring.

2.2 Hardware Resources: The Balancing Act of Performance and Cost

Resource-Constrained Devices (such as embedded sensors, single-board computers): Linux systems can reduce resource consumption by trimming the kernel (such as removing the graphical interface). The USR-EG628 controller, with a 4GB memory + 32GB storage configuration, still has sufficient resources to support Docker container deployment after running a Linux system.
High-Performance Devices (such as edge computing nodes, AI quality inspection equipment): Windows systems can leverage GPU acceleration (such as CUDA), while Linux systems optimize inference speed through TensorRT. A car factory found that a Linux system running the YOLOv5 model had a 30% higher frame rate than Windows.
Ultra-Low Power Consumption Devices (such as portable detectors): RTOS systems are the preferred choice due to their low power consumption. A medical device manufacturer extended equipment battery life from four hours to 12 hours using an RTOS system.

2.3 Development Efficiency: The Trade-Off Between Rapid Iteration and Customization

Rapid Integration Requirements: Windows systems provide ready-made industrial software (such as WinCC, LabVIEW), suitable for short-term projects. An electronics factory completed a production line monitoring system development in two weeks using WinCC configuration software.
Deep Customization Requirements: Linux systems support source-level modifications, suitable for long-term projects. An agricultural enterprise developed a customized irrigation algorithm based on a Linux system, reducing the AI model volume by 80% through model compression and lowering hardware costs by 60%.
Hybrid Development Requirements: The USR-EG628 controller supports a Linux + RTOS dual-kernel architecture, allowing simultaneous operation of real-time control tasks and non-real-time data analysis tasks. A logistics enterprise utilized this feature to achieve collaborative work between AGV navigation (RTOS) and path optimization (Linux).
