标准摘要
[中文适用范围]: 本国际标准规定了一种用于非关键监控@警报@监督控制@开环控制@和闭环控制应用的可靠且安全的无线操作方法。该标准定义了一个协议套件@,包括系统管理@网关注意事项@和安全规范@,用于与固定@便携式@和缓慢移动设备@经常在严格的能量和功率限制下运行的低数据速率无线连接。该标准的应用重点是过程自动化监控@的性能需求,其中可以容忍100毫秒左右的端到端通信延迟。本标准规定了以下内容: ?物理层服务定义和协议规范; ?数据链路层服务定义和协议规范; ?网络层服务定义和协议规范; ?传输层服务定义和协议规范; ?应用层服务定义和协议规范@,包括对协议隧道和网关的支持; ?安全和安全管理; ?供应和配置; ?网络管理;和 ?附加通信角色配置文件(即可以同时选择一个或多个)。 OSI 基本参考模型@应用层之上的功能,例如所谓的用户层和该层@的不同功能配置文件,没有得到解决。然而,附件 A 对此进行了简要讨论。 [外文原描述]: IEC 62734:2014 provides specifications in accordance with the OSI Basic Reference Model, ISO/IEC 7498-1, (e.g., PhL, DL, etc.). It is intended to provide reliable and secure wireless operation for non-critical monitoring, alerting, supervisory control, open loop control, and closed loop control applications. It defines a protocol suite, including system management, gateway considerations, and security specifications, for low-data-rate wireless connectivity with fixed, portable, and slowly-moving devices, often operating under severe energy and power constraints. The application focus is the performance needs of process automation monitoring and control where end-to-end communication latencies on the order of at least 100 ms can be tolerated.
