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

The invention discloses an MVB topology automatic converter. The device is characterized in that the device is characterized in that the converter comprises three relays Q1, Q2 and Q3 and three MVB connectors X1, X4 and X5, the relays Q1, Q2 and Q3 are connected in parallel, the MVB connector X1 is provided with a positive pin and a negative pin, the X4 is provided with eight pins, the X5 is provided with four pins, and the Q1, Q2 and Q3 are all connected with a compartment coupling signal through the positive pin and the negative pin of X1 for power supply; the first pin and the second pin ofthe X4 are connected with the first pin and the second pin of the X5 through Q1, and the fourth pin and the fifth pin of the X4 are connected with the fourth pin and the fifth pin of the X5 through Q2. Pins 1, 2, 4 and 5 of the X4 are respectively connected with pins 6, 7, 8 and 9 of the X4 through Q3. According to the invention, the purchasing cost is reduced, and the advantage of fixed MVB busdata transmission period can be fully utilized, so that the whole motor train unit 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...
