Description
Technical field
The present invention relates to the railroad train control technology, relate in particular to a kind of speed per hour 250km/h motor train unit train network control system.
Background technology
Train network control system is the per hour nerve center of (km/h) motor train unit of 250 kilometers of speed per hours; bearing the control of whole motor train unit; monitor; diagnosis and protection task; be responsible for finishing the operation control of train; monitor; diagnosis function; tractor equipment by networked control system of the train and management train; brake equipment; high-tension apparatus; auxiliary power supply; air-conditioning; traffic safety equipment; nearly all equipment such as car door and light equipment; in train operation; play an important role in the maintenance
Existing speed per hour 250km/h motor train unit train network control system adopts and meets TCN(Traincommunication network, TCN) the secondary bus equipment of standard.Four cars form a traction unit, at the inner MVB(Multifunction Vehicle Bus that adopts of each traction unit, MVB) communicate, and between each traction unit, adopt WTB(Wire Train Bus, wired train bus) communicate.
Fig. 1 is the constructional drawing of existing speed per hour 250km/h motor train unit train network control system.In Fig. 1, (each traction unit comprises end car, the trailer with pantograph, motor-car and trailer to show the speed per hour 250km/h motor train unit train network control system that is applied to the first traction unit and the second traction unit, each car that not shown traction unit comprises among Fig. 1, and only show the speed per hour 250km/h motor train unit train network control system that is applied to this first traction unit and this second traction unit), the MVB equipment in each traction unit is connected to the WTB/MVB gateway by MVB.
As shown in Figure 1, in this speed per hour 250km/h motor train unit train network control system, from left to right four MVB buses are respectively in the first traction unit: with the MVB bus 11 of MVB equipment connection in the end car of the first traction unit, with the MVB bus 12 with the MVB equipment connection in the trailer of pantograph of the first traction unit, with the motor-car of the first traction unit in the MVB bus 13 of MVB equipment connection, and with the trailer of the first traction unit in the MVB bus 14 of MVB equipment connection; Dextrosinistral four MVB buses are respectively in the second traction unit: with the MVB bus 21 of MVB equipment connection in the end car of the second traction unit, with the MVB bus 22 with the MVB equipment connection in the trailer of pantograph of the second traction unit, with the motor-car of the second traction unit in the MVB bus 23 of MVB equipment connection, and with the trailer of the second traction unit in the MVB bus 24 of MVB equipment connection.The MVB equipment that is connected in MVB comprises: the HMI(man-machine interface), ATC(driverless train control unit), HADS(hot box monitoring system), the HVAC(air-conditioning and ventilation system), the DCU(door control system), MBCU(main brake control unit), RIOM, MVB/RS485 gateway, DDU(remote data transmission device), the BC(battery charger) and the PIS(passenger information system) etc.
