广域通信用车辆探测数据

[中文适用范围]： 本国际标准规定了以下内容： • 探车系统和探数据的参考架构。该参考架构为探车系统提供了一般结构，在此结构内可以构建各种实际的探车系统，其物理特性可能不同（例如，在通信介质的选择上）。该参考架构用于： - 阐明本标准将使用的探车系统的主要构建块和逻辑互连； - 根据下述信息模型对探数据进行分类。 • 探数据元素和探数据的基本数据框架。该框架规定了如何定义探数据元素和探数据。具体而言，它提供以下内容： - 将探数据的信息模型（如ISO 14817中定义）映射到探数据元素/消息的规则。信息模型显示了探数据中涉及的实体和概念的逻辑结构。 - 探数据元素和探数据消息所需的特征。 - 探数据元素/消息的符号（在XML中）。 - 使用核心数据元素和基本数据元素（见下文）以及每个应用领域中数据元素扩展的规则。 • 核心数据元素定义。核心数据元素是旨在出现在每条探消息中的基本描述性元素。这些是探数据被感测时的位置和时间的元素。 • 初始探数据元素集。这些元素将在典型的探数据启用应用领域（如交通、天气和安全）中常用。标准化这些探数据元素有助于开发探车系统和分发探数据。这并不旨在列出所有探数据元素。 • 示例探消息。这些消息定义了如何组合探数据元素以向探处理中心传达信息。这并不旨在列出所有探消息。 图1描绘了上述范围。为了完全定义探处理，仅标准化探数据元素和探消息是不够的。还需要对处理后的探数据（探处理的输出）和下行链路元素和消息（用于将这些结果传送给车辆和其他用户）进行标准化。本国际标准规定了从车辆传输到陆地处理中心的重要的初始探数据元素集。其他探数据问题的标准化将在未来的工作中解决。 [外文原描述]： ISO 22837:2009 relates to vehicle probe data for wide are communications. It specifies the following. Reference architecture for probe vehicle systems and probe data, which provides a general structure for probe vehicle systems within which a wide range of actual probe vehicle systems can be built whose physical characteristics may differ (e.g., in their choice of communications medium). The reference architecture is used to: clarify the major building blocks and logical interconnections of probe vehicle systems for which this standard will be used; categorize probe data in accordance with the information model described below. Basic data framework for probe data elements and probe data, which defines probe data elements and probe messages, and specifically provides: rules for mapping information models (as defined in ISO 14817) of probe data to probe data elements/messages. The information models show the logical structure of entities and concepts involved in probe data; the required characteristics of probe data elements and probe data messages; the notation for probe data elements/messages (in XML); rules for using core data elements and basic data elements (see below), and extensions of data elements in each application domain. Core data element definitions, which are basic descriptive elements intended to appear in every probe message, i.e. the location and the time at which the probe data was sensed. Initial set of probe data elements, which are commonly used in typical probe data enabled application domains, such as traffic, weather, and safety. Example probe messages, which define how probe data elements are combined to convey information to probe processing centres.
