安全控制技术

安全控制技术包括用于预防或减轻工业环境中危险情况的各种方法、系统和设备。它在确保人员、设备和周围环境的安全方面发挥着至关重要的作用。

常用安全控制组件

安全传感器：这些传感器可检测危险情况，例如过大的力、压力、温度或靠近危险机械。

安全逻辑控制器：这些控制器根据预定义的安全规则和风险评估处理传感器数据并激活安全执行器。

安全执行器：这些执行器执行防止或减轻危险情况的操作，例如关闭机器、制动电机或隔离能源。

安全通信网络：这些网络促进了安全设备之间的安全可靠通信，从而实现了实时监控和协调响应。

安全控制功能

紧急停止：在检测到迫在眉睫的危险时立即启动机器或流程的关闭。

防护装置和联锁装置：在不符合安全条件时，防止进入危险区域或防止危险操作。

安全监控系统：持续监控安全参数，并在超过阈值时触发警报或干预措施。

危险能源的保护：隔离或锁定能源，以防止意外释放或激活。

安全标准和法规

安全控制系统必须遵守各种标准和法规，例如：

IEC 61508（功能安全）：定义功能安全的系统方法，确保安全功能可预测且可靠。

ISO 13849-1（机械安全 - 安全相关控制）：规定安全相关控制系统的设计、构造和集成的原则和要求。

NFPA 78（工业和商业场所电气标准）：涵盖工业设施的电气安全要求，包括安全控制系统。

Safety control technology

Safety control technologies include methods, systems and equipment used to prevent or mitigate hazardous situations in industrial environments. It plays a vital role in ensuring the safety of people, equipment and the surrounding environment.

Common security control components

Safety sensors: These sensors detect hazardous situations, such as excessive force, pressure, temperature, or proximity to dangerous machinery.

Safety logic controllers: These controllers process sensor data and activate safety actuators according to predefined safety rules and risk assessments.

Safety actuators: These actuators perform operations that prevent or mitigate dangerous situations, such as turning off machines, braking motors, or isolating energy.

Secure communication networks: These networks facilitate secure and reliable communication between security devices, enabling real-time monitoring and coordinated responses.

Safety control function

Emergency stop: The shutdown of a machine or process is initiated immediately when an imminent danger is detected.

Protective devices and interlocking devices: prevent entry into hazardous areas or prevent dangerous operations when safety conditions are not met.

Security monitoring system: Continuously monitor security parameters and trigger alarms or interventions when thresholds are exceeded.

Protection of hazardous energy sources: Isolate or lock down energy sources to prevent accidental release or activation.

Safety standards and regulations

Safety control systems must comply with various standards and regulations, such as:

IEC 61508 (Functional Safety) : defines a systematic approach to functional safety, ensuring that safety functions are predictable and reliable.

ISO 13849-1 (Safety of Machinery - safety-related controls) specifies principles and requirements for the design, construction and integration of safety-related control systems.

NFPA 78 (Electrical Standard for Industrial and Commercial Premises) : Covers electrical safety requirements for industrial facilities, including safety control systems.
