Problems solved by technology

Moreover, the fixed MVB network segment grouping method can only realize the grouping and connection between different MVB network segments, but it cannot realize the arbitrary addition of carriages in the same MVB network segment. The main reason is that the MVB network segment needs to be equipped with terminal resistors, which cannot be realized by current technology. Free configuration of MVB terminal resistance

Abstract

An MVB topology automatic converter, characterized in that it includes three relays Q1, Q2, Q3 and three MVB connectors X1, X4, X5, the relays Q1, Q2, Q3 are connected in parallel, and the MVB connector X1 is provided with positive and negative two X4 has 8 pins, and X5 has 4 pins. Q1, Q2, and Q3 are connected to the car connection signal through the positive and negative pins of X1 to supply power; the 1 and 2 pins of X4 pass through Q1 Connect pins 1 and 2 of X5, pins 4 and 5 of X4 are connected to pins 4 and 5 of X5 through Q2; pins 1, 2, 4 and 5 of X4 are respectively connected to pins 6, 7 and 5 of X4 through Q3 8, 9 four pins; the present invention reduces the cost of equipment procurement, and can make full use of the advantages of fixed MVB bus data transmission cycle at the same time, so that the EMU vehicle control software is stable and reliable.

Description

technical field [0001] The invention belongs to the field of train network control and monitoring systems, and in particular relates to an MVB topology automatic converter which is used in the MVB multifunctional vehicle bus and has a flexible marshalling function. Background technique [0002] Foreign rail transit vehicle manufacturers are striving to develop EMUs with flexible marshalling characteristics. For example, the German ICE EMUs can be composed of 7 to 14 cars, and the French TGV EMUs can be composed of 10 to 20 cars. Both can realize flexible grouping operation of trains. [0003] At present, EMUs using MVB multifunctional vehicle bus generally adopt the marshalling mode of fixed MVB network segments. If two different EMUs are required to have the ability of automatic marshalling and reconnection operation, a TCN gateway must be installed in the EMUs to transmit control signals, status data, diagnostic information, etc. between different EMUs. Moreover, the fix...
