18、TS 13149-8:2013 (E) 4 Introduction The Technical Specifications in the EN 13149 series provide rules for data communication systems on-board public transport vehicles. Part 8 together with part 7 and part 9 describes a complete solution parallel to, but independent of, parts 1-3 and part 4-6. Public

19、 Transport (PT) vehicles have an increasing array of information and communications systems, including ticket machines, Automated Vehicle Location (AVL) systems, destination displays, passenger announcement systems, vehicle monitoring systems etc. Other systems are beginning to be included such as a

20、dvertising screens, tourist guides, WiFi “hotspots” and infotainment. These systems may be provided by a number of different suppliers, and may need to be integrated. For instance a ticket machine may need location information to update fare stages; next-stop and destination information may be drawn

21、 from schedule information held in the ticket machine; and location systems may be used to drive signal priority requests. In addition, equipped PT vehicles will often have communications facilities to enable voice and/or data to be exchanged with the intermodal transport control system centre, othe

22、r PT vehicles, PT infrastructure, and roadside devices (for instance in requesting priority at traffic signals). Many types of communication channel are utilised, including public and private wireless communication networks. Without a clear technology framework, integrating these systems would requi

23、re complex technical discussions every time a device is procured. A large number of current and future communication networks will use the Internet Protocol (IP) as a core network technology. Existing parts of EN 13149 are not consistent with an IP network and do not support the use of associated pr

24、otocols. This makes it difficult for integrated on-board systems to use modern networks efficiently. If an IP approach is adopted, the PT vehicle begins to look like a local area network (LAN) of connected systems. In this context it is relevant to define a hardware network which makes use of IEEE 8

25、02 technologies these are much the most widespread basis for IP LANs worldwide. The parts 7 to 9 will describe this adaptation. This will facilitate: high quality intermodal passenger services based on intermodal PT information, integration of new PT services, lower cost, lower risks and a smoother

26、onboard integration of PT equipment, more efficient operation and maintenance of onboard PT equipment, and more efficient development of PT components. PD CEN/TS 13149-8:2013CEN/TS 13149-8:2013 (E) 5 1 Scope This Technical Specification specifies the physical layer of an onboard data transmission bu

27、s between the different equipment for service operations and monitoring of the fleet. This applies to equipment installed on board vehicles that are operating as part of a public transport network, i.e. in operation under public service contracts. This equipment includes operation aid systems, autom

28、atic passenger information systems, fare collection systems, etc. Equipment directly related to the safety-related functioning of the vehicle (propulsion management, brake systems, door opening systems, etc.) are excluded from the scope of this Technical Specification and are dealt with in other sta

29、ndardization bodies. Interfaces to such equipment or safety-critical networks can be provided through dedicated gateways. Part 8 covers the link between equipment inside vehicles consisting of one carriage only, e.g. buses and trolleybuses, as well as a set of carriages, e.g. trams and trains. For t

30、he described application, three communication systems are standardised under EN 13149. There is no ranking between the three communication systems. Parts 1, 2 and 3 describe the WORLDFIP communication system; Parts 4, 5 and 6 describe the CANopen communication system; Parts 7, 8 and 9 describe the I

31、P-based communication system. Part 71of the 13149 series specifies the Network and System Architecture for onboard equipment. It describes basic principles of communications including a general description of the network topology, addresses schematics, basic network services, a system overview and b

32、asic device architecture. Part 8 of the 13149 series specifies the Physical Layer for IP-communication networks onboard PT vehicles. This part specifies the cables, connectors and other equipment including pin assignment and environmental requirements. Part 92of the 13149 series specifies in detail

33、the Profiles of basic and generic Services and Devices as well as profiles of specific services and devices. This part 8-1 specifies wired communication networks onboard PT vehicles which are based on the Ethernet specification IEEE 802.3 10 Base T and 100 Base Tx. 2 Normative references The followi

The following chapters provide specific requirements for the applications within the scope of th

40、is Technical Specification. It is important to understand that electrical connections onto the communication network have important impact upon the network performance, and that the application is dependent upon the principles relevant to transmission lines rather than simple electrical power circui

41、ts. For the purposes of Part 8, all Ethernet ports of devices which are connected to the network shall work in accordance to: PD CEN/TS 13149-8:2013CEN/TS 13149-8:2013 (E) 7 IEEE 802.3 10 Base-T, or IEEE 802.3 100 Base-Tx. 5.2 Network Structure The general network structure (see figure below) is bui

42、ld up by end devices that are connected via switches. Key Box A End Device Box B Switch Figure 1 Ethernet Structure The following rules should be followed when installing an Ethernet network: a) the maximum cable length between a switch and a device or between two switches shall not exceed 100m in t

43、he half-duplex mode, and b) the number of connectors (Type 2, see Figure 4) in a cable between a switch and a device or between two switches shall not exceed six (6). 5.3 Cabling The Ethernet cable used shall fulfil IEC 61156-6 category 5e requirements: It should be free from CFCs, halogen, silicone
