用于数据收集、汇总和分析的监控和测量系统 第1部分：设备要求

[中文适用范围]： 本部分规定了用于数据采集、聚合及分析的监控和测量系统的设备要求。这些系统广泛应用于工业自动化、物联网、智能建筑等领域的数据处理。 [外文原描述]： IEC 62974-1:2024 specifies product and performance requirements for devices that fall under the heading of "monitoring and measuring systems used for data collection, aggregation and analysis", for industrial, commercial, and similar use rated below or equal to 1 kV AC and 1,5 kV DC. These devices are fixed and are intended to be used indoors as panel-mounted devices, or as modular devices fixed on a DIN rail, or as housing devices fixed on a DIN rail, or as devices fixed by other means inside a cabinet. These devices are used to upload or download information (energy measured on loads, power metering and monitoring data, temperature information, etc.), mainly for energy efficiency purposes. These devices are known as energy servers (ESE), energy data loggers (EDL), data gateways (DGW) and I/O data concentrators (IODC) and are grouped together under the family name of Data Management Devices (DMD). This document does not cover: • devices used only in the consumer market (living quarters) or household; • devices used in the smart metering infrastructure (e.g. smart meters); • devices used in the smart grid infrastructure; • devices used as IT servers in the information technology business; • power metering and monitoring devices (PMD); • I/O data concentrators already covered by a specific product standard; • communication protocols and interoperability; • power quality instruments (PQI); • software used for the data collection and analysis of the power quality for the supply side. IEC 62974-1:2024 cancels and replaces the first edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the performance criteria have been reviewed; b) EMC and safety requirements have been improved; c) mechanical requirements have been clarified and amended.
