25、f existing buildings for an acceptable indoor environment, practical energy conservation and efficiency. This part describes the software and the engineered functions used for building automation and control systems. The application of this series of standards for BACS is envisaged as follows: - the
26、 environmental design for all building types requires complex methods for automation and control. The functional integration of services other than HVAC e.g. lighting and electric power distribution control, security control, transportation, maintenance management or facilities management are genera
27、l tasks for all parties employed to develop an integrated multi-application system. This integration allows the user to take advantage of synergies between the different applications. This standard will give guidance to architects, consultants and contractors as well as to users on how to share such
28、 resources; - the innovation cycles between devices, systems and networks vary. To make it possible to add and to change existing devices, and extend the building network, several interfaces both proprietary and standardized are defined between the BACS network and the other systems. A manufacturer
29、can design a product, both to meet his specific marketing objectives and to give the option to integrate that special device into a multi-application BACS. Interfaces are also defined in appropriate parts of this standard along with the necessary communications protocol and conformance test required
30、 to support the interworking of devices; - a manufacturer, a systems house, or an electrical or mechanical contractor may assemble an implementation of a building automation and control system; - the application of this standard is not to standardize the hardware and software design or the architect
31、ure of a System, but to define the process for the creation of project specifications, where functionality and the quality of the solution are clearly defined. The purpose of this series of standards is intended for use by those involved in the design, manufacture, engineering, installation, commiss
32、ioning, operational maintenance and training of BACS when contracted, i.e.: as a guide to the terminology of the building automation and control trade. Unambiguous terminology is required for a complete and accurate conveyance of the intent and details of this standard; in product development, to av
33、oid unnecessary duplication of function or terminology, but should not place a restraint on the evolution of new products, systems or applications. A precise definition of system functionality is needed to prevent the overlap of functionality in different control system devices; as a basis for inter
34、facing products and systems. In order to interoperate, the elements of a BACS require a common data communication protocol and information model; as a basis for drawing up a project specification for the procurement of building automation and control products for systems suppliers and customers. The
35、 successful design, procurement, installation, and operation of BACS require careful management and integration of the various aspects of the project; as a code of practice for proper commissioning prior to handover of a system; by educational establishments wishing to train people in the field of b
36、uilding automation and control systems. This entire series of BACS standards consists of the following contents: 5egaP ENISO164843:2003Page5 ENISO164843:2005 Part 1: Overview and vocabulary (in preparation) Part 1 of this standard describes the objectives and interrelationships of all parts of this
37、standard. It provides an overview and detailed information about the structure of the related series of standards for the BACS industry. This part of the standard provides also the vocabulary with terms and definitions for the understanding of the entire series of this standard and it contains a tra
38、nslation of the main terms in English, French, Russian and German in an informative annex. This ongoing work is coordinated at expert level with standards work from ISO/TC 205 WG 3 and CEN/TC 247/WG 2, WG 3, WG 4 and WG 5. Each specific part of this standard contains its dedicated necessary terms an
39、d abbreviations/acronyms out of this part. Part 2: Hardware Part 2 of the standard specifies the requirements for the hardware to perform the tasks within a BACS. Part 2 provides the terms, definitions and abbreviations for the understanding of Part 2 and Part 3. Part 2 relates only to physical item
40、s/devices, i.e.: devices for management functions, operator stations and other human system interface devices; controllers, automation stations and application specific controllers; field devices and their interfaces; cabling and interconnection of devices; engineering and commissioning tools. Part
41、2 shows a generic system model to which all-different types of BACS and their interconnections (BACS network) can fit. A graphical concept of the BACS network in terms of LAN and internetwork topology will be provided in Part 5 of this standard. Regional amendment(s): Regional amendments can specify
42、 the local requirements of physical and electrical characteristics, the verifications for BACS devices and equipment, and the code of practice for the physical installation of systems. The amendments refer to the regional implementations of the relevant IEC standards. Part 3: Functions (refer to the
43、 scope of this part) Part 4: Applications (in preparation) Part 4 of the standard specifies the requirements for specific communicating applications/devices, e.g. for general room automation and for sophisticated optimization of controls for heating, fan coil and induction units, CAV, VAV and radian
44、t cooling. This ongoing work will be coordinated at expert level with standards work from ISO/TC 205 WG 3 and CEN/TC 247. Part 5: Data Communication Protocol Part 5 of the standard specifies data communication services and protocols for computer equipment and controllers used for monitoring and cont
45、rol of HVAC output positioning/setpoint: analog output object, analog output value; binary input counting: counter input value, totalised value, accumulated value; input state: binary input object, binary input value, multi-state input; output switching: binary output object, binary output, multi-st
46、ate output; text string values; schedule information; alarm and event information; files; and control programs and parameters respectively. This protocol models each building automation and control system as a collection of data structures called objects, the properties of which represent various as
47、pects of the hardware, software, and operation of the device. These objects provide a means of identifying and accessing information without requiring knowledge of the details of the devices internal design or configuration. An overview of possible integration with other systems in buildings, e.g. f
48、ire, security, access control, maintenance and facilities management, is shown in Figure 1 of Part 2 of this standard. Part 6: Data Communication Conformance testing (in preparation) Part 6 of the standard specifies the technical requirements of the conformance test suite and the methods for testing the products for the conformance with the protocol. It provides a comprehensive set of procedures for verifying the correct implementation of each capability claimed on a BACS network protocol implem
