[0003] At present, there are not many trains using double-connected trains, so there are few control methods for the air compressors of double-connected urban rail trains. Once the air compressor of a train unit in a double-connected train fails, it will directly cause The total wind pressure drops below the lower limit of the wind pressure, which may even lead to the failure of the normal operation of the double train. control

Embodiment Construction
[0018] A control method for an air compressor of a double-connected urban rail train, such as figure 1 shown, including the following steps:
[0019] 1) For the first time after the reconnection of the urban rail train, the four air compressors in the two train units of the reconnection train are blown at the same time, and when the total wind pressure of a certain train unit reaches the upper limit of the wind pressure, stop the train unit The air compressor blows until the total wind pressure of the two train units reaches the upper limit of wind pressure;
[0020] 2), after the two train units of the double-connected train use wind, the total wind pressure drops. When the total wind pressure of one of the train units is lower than the wind pressure reference value, such as 750kPa, the main air compressor in the train unit blows the wind; When the main air compressor in the train unit fails, the slave air compressor in the train unit blows air; when both the main air compre...

The invention discloses a method for controlling an air compressor of a multi-connection city rail train. The method is mainly used for controlling the air compressor when the city rail train is in multi-connection running, and mainly comprises the following main contents: when the train is in multi-connection running, each train wind supply unit in two train units operates at normal condition to supply wind to the multi-connection train, so as to satisfy normal running requirements; a master-slave compressor in the train unit is controlled according to odd-numbered days or even-numbered days; when one train wind supply unit in some train fails to work, the other train wind supply unit in the multi-connection train is started up, so as to satisfy the running requirements of the train; and when the two wind supply units in some train fail to work, the two train wind supply units in another train operate at the same time, so as to satisfy the wind supply requirements of the multi-connection train.
Description
technical field [0001] The invention relates to a control method for an air compressor of a double-connected urban rail train, which is suitable for controlling the air compressor during the double-connected operation of the urban rail train. Background technique [0002] Most of the existing urban rail trains are controlled by air compressors in the form of a single row. Urban rail trains are generally equipped with two sets of air source systems, one is the main (main air compressor), and the other is used as a backup (slave air compressor) machine), the control of master and slave air compressors can be implemented in various forms such as single and double day information or head car operation. When one air compressor fails, the other air compressor starts, and the two are redundantly set. [0003] At present, there are not many trains using double-connected trains, so there are few control methods for the air compressors of double-connected urban rail trains. Once the ...
