This common user interface provides input and output methods for user information exchange to access, monitor and control applications running on home cluster systems.
This will be accomplished using the HES Gateway (ISO/IEC 15045 series) and related interoperability standards (ISO/IEC 18012 series). The messages specified in this standard are transported by using the HES-CLME specified in ISO/IEC 18012-4.
A home cluster system is implemented by interconnecting several devices to deliver one or more applications. A cluster may function independently of other clusters. Cluster devices include sensors, actuators, a controller, and user interfaces. Multiple home cluster systems may be installed and operated in a single home for the following reasons:
• There are various types of application domains in the home such as lighting, safety, air conditioning, telecommunications, and audio/video, etc. One or more applications are implemented by the constituents of a cluster. If a user purchases several applications, multiple home cluster systems may be installed in a home.
• Home application vendors usually provide systems implemented in clusters of required devices. Depending on the user's needs, several application systems, possibly from different manufacturers, may be installed in a home as separate clusters.
A customer may access a device in a cluster via a user interface provided for that cluster. With multiple clusters a user must learn how to operate a range of different interfaces. This standard provides the cluster-to-cluster interworking foundation necessary for a single common user interface to manage applications in multiple clusters.
Application-to-application and the resulting device-to-device collaboration are essential for providing integrated services in a multi-device HES environment. For example, if a fire monitoring system detects a fire, the indoor lights should be turned on and the fire announcements should be broadcast through available speakers in the house for prompt evacuation of the residents, the ventilation blowers should be stopped to avoid spreading the fire, and the public fire service should be contacted. This requires collaboration among fire detectors, indoor lights, speakers, HVAC and telecommunication devices. If the devices are located in different clusters, cluster-to-cluster interworking is required for collaboration among them.
In practice, a safety monitoring cluster might send out a fire-detected message and a lighting cluster might be ready to activate a lighting scene that alerts the occupant by turning on or flashing the appropriate lights. However, the two clusters may not have a way to communicate with each other especially if supplied by different manufacturers possibly using different protocols and messages. This standard solves that problem by providing the necessary interworking and interoperability functionality to ensure that the clusters can work together.
When the cluster systems are in different HANs or use different protocols, the interworking is accomplished using the HES Gateway (ISO/IEC 15045 series) and related interoperability standards (ISO/IEC 18012 series). For interworking between cluster systems using the same protocols and belonging to the same HAN, HES gateway services may optionally be used if the cybersecurity, privacy and safety features of the HES Gateway are desired. This standard does not require the Internet to operate, but can connect to the Internet if the application requires.
This standard specifies the architecture for interworking home cluster systems where
– The home cluster systems use different HANs or protocols, or
– The home cluster systems use the same HANs and protocols plus the services of the HES gateway.
