工业自动化安全第一解决方案简述

•Convergence of hardware and software systems–The need for seamless integration and interoperability–Assurance of overall industrial automation equipment safety and performance–The challenges of obtaining safety certificationSecurity and Safety: Working TogetherDeveloping functional safety features requires a multifaceted approach that integrates hardware, software, andoperations. Model-based design methodologies and simulation tools facilitate the rapid prototyping and validationof safety-critical systems, streamlining the development process and accelerating time-to-market. Advancementsin embedded systems, AI-based algorithms, and cybersecurity protocols further enable sophisticated safety-criticalsystems that are resilient to cyberthreats and external interference — though they also add to system complexity.Functional safety becomes even more important for software utilizing these advanced and autonomous systems.And while safety focuses on mitigating risks associated with system malfunction and failure, security addressesthreats posed by malicious actors and cyberattacks. When developers integrate robust security measures into safety-critical systems, they can mitigate the risk of unauthorized access, data breaches, and system tampering, safeguard-ing the integrity and reliability of their products.Regulatory Landscape for SafetyThe industrial automation industry is subject to stringent regulatory frameworks that govern safety standards andrequirements. Standards such as IEC 61508 provide guidelines for the design, implementation, and validation ofsafety-related control systems, and ensuring compliance is essential to mitigate legal liabilities and to uphold repu-tation. Functional safety certification programs for IEC 61508 standards are offered globally by several recognizedcertification bodies, including Intertek, SGS, TÜV Rheinland, TÜV SÜD, and UL.REAL-TIME OPERATING SYSTEMS FOR SAFETY-CERTIFIED APPLICATIONSAny mission-critical device, system, or component in industrial automation, robotics, medical, automotive, or other indus-tries needs to be safety certified. A robotic arm must not harm workers; an automatic braking system must work instantlywhen needed. To get this assurance, the system software needs to run on a real-time operating system (RTOS) thatutilizes multi-core processing and that has been certified according to specific standards. This functional safety supportneeds to continue throughout the product’s lifecycle, even in its legacy stage.Tailored Linux Development for AI, ML, and Deep Learning (DL)As industrial automation and robotics incorporate autonomous middleware, AI, ML, and deep learning (DL), much ofthe software system development will depend on Linux. For devices and equipment to operate in the field, it is criticalto minimize the Linux distro.In safety-critical scenarios, this entails integrating Linux into a system traditionally reliant on an RTOS. The inclusionof AI/ML algorithms, often affiliated with Linux, then becomes imperative. This necessitates applications and systemscapable of bridging both operating systems, prompting system integrators to adeptly navigate and harmonize theirdiverse requirements.Hypervisor Technology for InteroperationSilicon technology is advancing: The latest processors currently contain 24 to 40 cores on a single system-on-chip (SoC);more cores will be on future versions. For systems to comprise a safety-certified RTOS and an embedded Linux OS,operating side by side on a single SoC, developers rely on virtualization and software container technology. It is criticalto have the means to monitor both systems with high-speed communication. This is where a hypervisor that is certified,rapid, and capable of managing the host operating system(s) is a requisite.2 WIND RIVER PRODUCTS AND SERVICES FOR FUNCTIONAL SAFETYWind River offers long experience and an extensive portfolio of software and services that lead the way in functionalsafety development in industrial automation:•More than 40 years working with industrial automation developers•Safety-certified products•Products and services that enable modern Industrial 4.0 technologies•Support for delivery of 5G wireless communication to the industrial segment•Support for implementation of safety systems in industrial, aerospace, automotive, defense, robotics,medical, rail, and moreWind River has extensive expertise and experience meeting the safety-critical standards of crucial sectors, including flightsafety (DO-178C DAL A), industrial (IEC 61508), rail (EN 50126/8/9), and automotive (ISO 26262).FUNCTIONAL SAFETY–CERTIFIABLE SOFTWAREVXWORKS CERT EDITIONVxWorks®Cert Edition is a platform for safety-critical applications that require DO-178C, ISO 26262, IEC 61508, IEC 62304;or certification evidence in the avionics, automotive, industrial automation, and medical device industries.>>Learn MoreAbout VxWorks Cert EditionWIND RIVER HELIX VIRTUALIZATION PLATFORMWind River Helix™ Virtualization Platform, a Type
