标准摘要
[中文适用范围]： 本文件定义了用于数据交换的平台特定模型 (PSM)，该模型专门使用 ASN.1 和 TCP/UDP（传输控制协议/用户数据报协议）数据报，这些数据报在本文件的第一版中被定义为 AP-DATEX（应用程序配置文件数据交换）和其他互联网协议 (IP) 网络的“DATEX-ASN”。PSM 是用于交换的平台独立模型 (PIM) 的实际实现。本文件规定了使用 TCP/UDP 数据报在 ITS 的不同系统之间进行通信的消息规则和程序。本文件主要涉及通信接口。它旨在满足智能交通系统 (ITS) 的独特要求。但是，它也以通用方式设计，因此也可以用于其他数据交换。 [外文原描述]： This document defines a platform-specific model (PSM) for data exchange, which specifically uses ASN.1 and TCP/UDP (transmission control protocol/user datagram protocol) datagrams which were defined as “DATEX-ASN” in the first edition of this document for AP-DATEX (application profile-data exchange) and other Internet protocol (IP) networks. A PSM is an actual implementation of a platform-independent model (PIM) for exchange. This document specifies the message rules and procedures for communication between different systems for ITS using TCP/UDP datagrams. This document deals mainly with the communication interfaces. It has been designed to meet the unique requirements of intelligent transport systems (ITS). However, it has also been designed in a generic fashion and thus can be used for other data exchanges as well.
