这是ASHRAE研究项目1011-RP“公用事业/能源管理和控制系统（EMCS）通信协议要求”的一篇论文的第二部分该项目的重点是定义与能源相关的信息服务，并分析实现这些服务的数据需求。定义了以下九种信息服务，并分析了它们的通信和数据需求:（1）收入电表读数（电、气、水和加热和冷却能量），（2）服务质量监测，（3）实时定价传输，（4）负荷管理服务，（5）现场发电监控，（6）能效监测，（7）天气报告和预报服务，（8）室内空气质量监测，（9）电力交易所的动态需求投标。 本文介绍了通用应用服务模型（Common Application Service Models，CASM）作为一种数据建模框架，用于在使用各种计算平台的不同网络中实现这些服务的拓扑独立性。将通过实时定价通信的示例，给出并进一步描述实时定价费率计划的详细数据模型。本文最后给出了一种映射方法，将为上述服务定义的数据对象从CASM框架映射到BACnet协议。单位:非引文:ASHRAE交易，第107卷，第。1.

This is part two of a paper that presents an excerpt of ASHRAE Research Project 1011-RP, "Utility/Energy Management and Controls System (EMCS) Communication Protocol Requirements." The focus of this project was on the definition of energy-related information services and the analysis of data requirements to enable these services. The following nine information services were defined, and their communication and data requirements were analyzed: (1) revenue meter reading (electricity, gas, water, and heating and cooling energy), (2) quality of service monitoring, (3) real-time- pricing transmission, (4) load management service, (5) on-site generation supervisory control, (6) energy efficiency monitoring, (7) weather reporting and forecasting services, (8) indoor air quality monitoring, and (9) dynamic demand bidding into a power exchange. This paper introduces the Common Application Service Models (CASM) as a data-modeling framework for achieving topology independence in the implementation of these services in diverse networks using a wide range of computing plat-forms. A detailed data model for a real-time-pricing rate schedule will be presented and further described by means of an example of a real-time-pricing communication. The paper concludes with a mapping approach to map data objects defined for the above services from a CASM framework to the BACnet protocol.Units: None
