EN 50090-6-1:2017 5 1 Scope This European Standard defines a standardized web service based interface between Home and Building HBES Open Communication System and other inform
35、ation technology (IT) systems. The standardized interface is encapsulated in a gateway device, the HBES Gateway, which is able to communicate with both the Home and Building HBES Open Communication System and the connected IT systems. The HBES Gateway implements a set of encoding standards (see 10.2
36、) as well as various message exchange protocols (see 10.3) to enable remote access to the Home and Building HBES Open Communication System via the Internet or another wide area network (WAN). For this purpose, gateway profiles define different implementation levels (see 10.4). 2 Normative references

40、Exchange WS Web Services 4 Overall introduction Home and Building HBES Open Communication System is dedicated to the control and monitoring of networked building automation systems (BASs). Currently, Home and Building HBES Open Communication System has limited capability to communicate with other sy
41、stems, as a result of the use of different protocols, incompatibility or various other restrictions. For the integration of Home and Building HBES Open Communication System and for solving specific problem scenarios, customized solutions are currently on offer. A standard interface between the HBES
42、world and the remaining systems would however constitute a common link to bridge the gap and integrate Home and Building HBES Open Communication System into systems like the traditional Internet or the emerging Internet of Things (IoT). A standard bridge between Home and Building HBES Open Communica
43、tion System and IT systems based on Web services (WSs) is currently missing to support upcoming use case scenarios. This standard specifies such a standard interface. BS EN 5009061:2017EN 50090-6-1:2017 6 5 General technical introduction to HBES Web Services The HBES Gateway is an abstract concept,
44、and thus not restricted to any hardware requirements or limitations. Constrained devices can be used as well as enterprise systems as HBES Gateway device. It shall be kept in mind that some configurations may overload the used hardware regarding the mentioned limitations. For example, a computationa
45、lly intensive message exchange protocol cannot be used in resource-constrained HBES Gateways. However, the HBES Web services specification defines the HBES Gateway in an abstract and platform-independent way irrespective of any particular hardware. Figure 1 sketches the intended setting containing t
46、he Home and Building HBES Open Communication System, the IT systems and the HBES Gateway between these two components. Figure 1 General intention of the HBES WS interface In a first version, the HBES Gateway and its WS interface is based on OASIS Open Building Information Exchange (OBIX). The OBIX i
47、ntegration is specified in Clauses 8 and 9. The HBES Gateway shall allow browsing of information on the Home and Building HBES Open Communication System and reading or modifying runtime data of devices, Data points, Functional Blocks, Interface Objects or channels. Thus, any high level management us
48、e case to manipulate or monitor the underlying Home and Building HBES Open Communication System is covered by this standard and can be implemented using the presented interfaces. By default, the HBES Gateway is intended for two target groups: BS EN 5009061:2017EN 50090-6-1:2017 6 5 General technical
