16、SSION _ ELECTRONIC RAILWAY EQUIPMENT ON-BOARD MULTIMEDIA AND TELEMATIC SUBSYSTEMS FOR RAILWAYS Part 2: Video surveillance/CCTV services FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees
17、(IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Repor
18、ts, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and no
19、n- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements
20、of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are
21、 accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote inter
22、national uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in t
23、he latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All user
24、s should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or othe
25、r damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. U
26、se of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent
27、 rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a Technical Specification when the required support cannot be obtained for the publication of an International Standard, despit
28、e repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical Specifications are subject to review within three years of publication to decide whether th
29、ey can be transformed into International Standards. IEC TS 62580-2, which is a Technical Specification, has been prepared by IEC technical committee 9: Electrical equipment and systems for railways. PD IEC/TS 62580-2:2016IEC TS 62580-2:2016 IEC 2016 5 The text of this specification is based on the f

T
35、he on-board video surveillance/CCTV system is a subsystem of OMTS, providing services for on-board surveillance and the security issue of the train and passengers. It serves as the crucial source of information for train operator, security organizations and first responders. The basic system functio
36、nality contains video/audio capture, recording, retrieval, replay, display, etc. This Technical Specification will be useful to those responsible for establishing operational requirements, writing specifications, selecting devices, installing, commissioning, using and maintaining the on-board video
37、surveillance/CCTV system. This specification is divided into the following sections: a) system breakdown: divides the on-board video surveillance/CCTV system into four components based on their functionality, including video capture component, video storage component, video display component and vid
38、eo analysis component; b) function breakdown: gives the function list that system may offer from the users point of view, and presents the function blocks of system according to the functional breakdown, which includes video environment, system management and system security. Within video environmen
39、t, it contains the basic functions that system could provide, such as to capture video, to record video, to retrieve video, to export video, to replay video, to display video, to analyse video and manage interconnection; c) requirements: describes the requirements of video environment, system manage
40、ment and security as well as video transmission in which transmission performance, protocol and IP interoperability implementation based on Web service have been introduced; Some use cases of the on-board video surveillance/CCTV system are given in Annex A.

41、IEC 2016 7 ELECTRONIC RAILWAY EQUIPMENT ON-BOARD MULTIMEDIA AND TELEMATIC SUBSYSTEMS FOR RAILWAYS Part 2: Video surveillance/CCTV services 1 Scope This part of IEC 62580, which is a Technical Specification, specifies the on-board video surveillance/CCTV system functionality and requirement for the p
42、urpose of interoperability between components of on-board video surveillance/CCTV systems in the same vehicle and subsystems in different vehicles of the same train, which means two levels of interoperability are considered, one is interoperability between components and another is between subsystem
43、s. This specification gives guidelines for: system breakdown structure of the on-board video surveillance/CCTV system; function breakdown structure of the on-board video surveillance/CCTV system, and requirement of the on-board video surveillance/CCTV system. This specification is applicable to any
44、type of train, for example open trains, multiple unit trains and closed trains. As illustrated in Figure 1, this part of IEC 62580 provides video surveillance/CCTV services of monitoring, recording and retrieval of data, etc. This specification follows the general OMTS requirement defined in IEC 625
45、80-1. The communication network of on-board video surveillance/CCTV system is based on the network defined by the IEC 61375 series, in which IEC 61375-2-5 and IEC 61375-3-4 define communication between and within consists, respectively, IEC 61375-2-3 lays out the communication profile for the backbo
46、ne which is used for the train coupling, and IEC 61375-2-6 1provides the support for the communication between on-board system and ground wayside infrastructures. The general system requirement of on-board video surveillance/CCTV system is developed based on IEC 62676 series with supplementing the s
47、pecial requirement for railway application. For interoperability implementation between components of system and subsystems, this specification makes reference to IEC 62676-2-3, which specifies a compliant IP video protocol and interface based on Web services. Special requirements for railway, such
48、as device discovery between consists and within a consist, as well as network compliant to the IEC 61375 series are also defined here. In addition, IEC 62676-4 gives recommendations and requirements for the selection, planning, installation, commissioning, maintaining and testing for use in security
49、 applications. Finally, the requirement of exported data of on-board video surveillance/CCTV system is compliant with ISO 22311 if system is for security purpose. _ 1Under consideration.
