现场设备是智能交通系统（ITS）的关键部件。现场设备包括交通信号、信息标志、气象站、交通传感器、用于连接ITS（C-ITS）环境的路边设备等。 现场设备通常需要与其他外部实体（经理）交换信息。现场设备可能非常复杂，需要对许多数据交换概念进行标准化。因此，ISO 20684？系列分为几个单独的部分。 ISO 20684？系列的这一部分确定了几乎所有现场设备管理的基本用户需求，并将这些需求追溯到可互操作的设计。这包括识别设备、其功能和状态的能力。 注？本文件类似于NTCIP 1103？v03和NTCIP 1201？v03的部分。 ISO 20684-1提供了有关ISO 20684？系列如何与整体ITS体系结构相关的其他详细信息。

Field devices are a key component in intelligent transport systems (ITS). Field devices include traffic signals, message signs, weather stations, traffic sensors, roadside equipment for connected ITS (C-ITS) environments, etc. Field devices often need to exchange information with other external entities (managers). Field devices can be quite complex necessitating the standardization of many data concepts for exchange. As such, the ISO 20684 series is divided into several individual parts. This part of the ISO 20684 series identifies basic user needs for the management of virtually any field device and traces these needs to interoperable designs. This includes the ability to identify the device, its capabilities, and its status. NOTE       This document is similar to portions of NTCIP 1103 v03 and NTCIP 1201 v03. ISO 20684-1 provides additional details about how the ISO 20684 series relates to the overall ITS architecture.
