38、 and train backbones defined by this part of IEC 61375. The TCN has a hierarchical structure with two levels of networks, a train backbone and a consist network: a) for interconnecting vehicles in close or open trains, this part of IEC 61375 specifies train backbones with different characteristics;
39、b) for connecting standard on-board equipment, this part of IEC 61375 specifies consist networks with different characteristics. The general architecture of the TCN, which is defined in this part of the standard, shall c) establish the rules for interconnecting consist networks with train backbones,
40、 as identifying the interfaces; defining the principles of how train topology changes can be discovered; defining the basic communication services provided by train backbones to be used by consist networks; d) establish basic rules for the train backbone and for the consist network; e) establish rul
41、es for communalities in operation, as: patterns for the communication between users; addressing principles; data classes to be supported. BS EN 61375-1:2012 8 61375-1 IEC:2012 ELECTRONIC RAILWAY EQUIPMENT TRAIN COMMUNICATION NETWORK (TCN) Part 1: General architecture 1 Scope This part of IEC 61375 a
42、pplies to the architecture of data communication systems in open trains, i.e. it covers the architecture of a communication system for the data communication between vehicles of the said open trains, the data communication within the vehicles and the data communication from train to the ground. The
43、applicability of this part of IEC 61375 to the train network technologies allows for interoperability of individual vehicles within open trains in international traffic. The data communication systems inside vehicles are given as recommended solutions to cope with the said TCN. In any case, proof of
44、 compatibility between a proposed train backbone and a proposed consist network will have to be brought by the supplier. This part of IEC 61375 may be additionally applicable to closed trains and multiple unit trains when so agreed between purchaser and supplier. NOTE 1 For a definition of open trai
45、ns, multiple unit trains and closed trains, see Clause 3. NOTE 2 Road vehicles such as buses and trolley buses are not considered in this part of IEC 61375. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its
