标准范围

ISO 22837:2009涉及用于wide are通信的车辆探头数据。它指定了以下内容。探测车系统和探测数据的参考架构，其提供了探测车系统的通用结构，在该结构内可以构建物理特性可能不同(例如，在通信介质的选择上)的广泛范围的实际探测车系统。参考架构用于:阐明本标准将用于的探测车系统的主要构件和逻辑互连；根据下面描述的信息模型对探针数据进行分类。探针数据元素和探针数据的基本数据框架，定义了探针数据元素和探针消息，具体提供:用于将探测数据的信息模型（如ISO 14817中定义的）映射到探测数据元素/消息的规则。信息模型显示了探针数据中涉及的实体和概念的逻辑结构；探测数据元素和探测数据报文所需的特征；探测数据元素/消息的符号（XML）；使用核心数据元素和基本数据元素的规则（见下文），以及每个应用程序域中数据元素的扩展。核心数据元素定义，其是旨在出现在每个探测消息中的基本描述性元素，即探测数据被感测的位置和时间。探测数据元素的初始集合，通常用于典型的支持探测数据的应用领域，如交通、天气和安全。示例探测消息，其定义如何组合探测数据元素以向探测处理中心传送信息。

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.
