消费电子产品和网络的服务诊断接口 ECHONET 的实现

[中文适用范围]： 本标准规定了适用于消费电子产品和服务诊断接口的网络实施要求，特别是针对ECHONET协议的应用。它涵盖了多种类型的诊断服务，包括独立产品的自我诊断、设施或家庭电器网络中的诊断以及远程诊断。此外，详细描述了测试器硬件和软件的需求，以及控制协议的详细格式，包括ECHONET及其简化版本（ECHONET Lite）的数据传输机制。 [外文原描述]： IEC 62394:2024 specifies requirements for service diagnostic software to be implemented in products that incorporate a digital interface. It does not specify requirements for carrying out remote diagnosis or for manufacturer-dependent software. The Service Diagnostic Interface (SDI) requires an external controller (exclusive or general-purpose/PC) into which service diagnostic software can be loaded. Parts of the controller software are standardized while other parts are proprietary to the manufacturers. To reach a common approach in servicing all products from all manufacturers, it is necessary to standardize specific items to be tested in products and certain aspects of controllers' diagnostic software. The SDI is based upon ECHONET specification version 2.11, ECHONET Lite specification version 1.13, and APPENDIX Detailed Requirements for ECHONET Device objects Release Q rev. 1, because this interface will be used in future products. The use of this connection and existing communication protocols enable implementation in products at a low cost, with maximum flexibility and efficiency. The SDI consists of • specific hardware and software requirements of the device under test (DUT); • specific requirements of the controller: – the service software; – an ECHONET interface; • the connection between the controller and the DUT. This document provides the minimal requirements necessary to carry out computerized diagnosis. It covers the standardized software of the controller as well as the standardized software and provisions in the DUT. IEC 62394:2024 cancels and replaces the fourth edition published in 2022. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) updates of the device object super class specifications for the property configurations shared by all device objects; b) modification and addition of the property configurations defined by each object; c) addition of new device objects and their property configurations; d) updates to Bibliography.
