ISO IEC TR 15044:2000 pdf download.Information technology - Terminology for the Home Electronic System (HES)
1 Scope
The home electronic system (HES) provides a common method for interfacing equipment with a variety of home control systems (HCS) such as sensors, actuators, appliances， user interfaces, controllers, switches etc. An HCS is a local area network specialized for residential communications, commonly called home automation.
This terminology is applicable to all standards and technical reports dealing with HES.
2 Terminology
2.1 application
field of use of an HES. An HES may support more than one application
2.2 application object
an HES object located within the HES device application process
2.3 application process
an element within an HES which performs the information processing for a particular application
2.4 application protocol
standardized protocol for the exchange of information between application processes in an HES. It is transported without interpretation by the home network resources
2.5 architecture
conceptual structure of systems that are to communicate with each other
2.6 bridge
functional unit interconnecting two home network systems that use the same network layer protocol but where there may be some differences in the link layer protocol
2.7 classes of home control systems
characterization of home control systems based on their transport capabilities
2.8 connection
association established between two peer entities across a network (or part of a network) for the purpose of communication between the entities. The association is explicitly established at some point in time, and exists until explicitly ended
2.9 connection-mode service
service providing communication between two entities within the context of a connection established between the entities
2.10 connectionless-mode service
service providing communication between two entities not within the context of a connection established between the entities
2.11 control channel
a communication channel that is established between two or more entities for the primary purpose of exchange of HES control and monitoring messages
2.12 controller
any device with the capability of controlling and possibly monitoring other devices
2.13 device
physical implementation of functions belonging to one or more functional groupings providing a service directly for an end-user
2.14 device application process
element within a device that performs information processing for a particular application.Device application processes can represent manual, automated, computerized or physical processes
2.15 domain
range of validity
NOTE When used for a specific concept, the exact domain should be stated, for example application domain, user domain.
2.16 end user
entity outside the home control system domain that uses the services and functions of the home control system
2.17 flow control
function that controls the flow of data within a layer. It regulates the rate at which information is exchanged between peer entities
2.18 functional grouping
set of functions performing part of the operations of a home control system
NOTE The functions in a functional grouping might be performed in one or more pieces of equipment and the functions of several functional groupings might be performed in one piece of equipment.ISO IEC TR 15044 pdf download.
