现场设备是智能交通系统（ITS）的关键组件。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，因此需要对许多数据概念进行标准化以进行交换。因此，ISO20684系列分为几个单独的部分。本文件规定了触发触发器的多种机制的需求、要求和设计，这些触发机制会导致设备尝试执行操作。其他文档中定义了特定类型的操作，可以包括发送通知（ISO/TS 20684-4）、将数据输入日志以便稍后检索（ISO/TS-20684-5）和/或启动基于SNMP的请求（ISO/TS20684-6）。注释1NTCIP 1103和NTCIP 1201的某些部分与本文件有相似之处。注释2ISO 20684-1提供了有关ISO如何20684系列涉及整个ITS架构。

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 several individual parts.This document specifies the needs, requirements and design for multiple mechanisms to fire triggers, which result in the device attempting to perform an action. Specific types of actions are defined in other documents and can include sending notifications (ISO/TS 20684-4), entering data into a log for later retrieval (ISO/TS 20684-5), and/or initiating SNMP-based requests (ISO/TS 20684-6).NOTE 1   There are similarities between certain portions of NTCIP 1103 and NTCIP 1201 and this document.NOTE 2   ISO 20684-1 provides additional details about how the ISO 20684 series relates to the overall ITS architecture.
