Embodiment Construction

[0031] The technical solutions in the present invention are clearly and completely described below in combination with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] A method for controlling the main compressor of a concentrated power EMU provided by the present invention includes:

[0033] 1. Obtain the pressure values ​​of the first main air cylinder of the power car, the second main air cylinder of the power car and the second main air cylinder of the control car.

[0034] Such as figure 1As shown, for a short EMU, it includes a power car, a control car and a multi-section intermediate car. The power car or the control car is l...

Abstract

The invention discloses a control method and system for a main compressor of a power centralized motor train unit. The pressure value of the first main air cylinder of the power vehicle is used as a main compressor start-stop judgment basis, the pressure values of the second main air cylinder of the motor vehicle and the second main air cylinder of the control vehicle are used as the start-stop judgment basis of the main compressor so that the situation that the second main air cylinder of the control vehicle is far away from the air source to cause insufficient total air pressure to easily trigger the vehicle set to block traction is avoided; meanwhile, when the pressure values of the first main air cylinder and the second main air cylinder of the vehicle are both higher than a second preset value and the pressure values of the second main air cylinders of other vehicles are higher than a third preset value, the main compressor of the vehicle is controlled to stop, and the problem that vehicle air equipment is damaged due to the fact that the pressure values of the first main air cylinder and the second main air cylinder of the power vehicle are too high is solved.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a control method and system for a main compressor of a power centralized train set. Background technique [0002] In recent years, with the development of EMU technology, power-concentrated EMUs have been popularized in China due to their flexible formation, lower manufacturing, operation, and maintenance costs than power-distributed EMUs, and higher comfort. [0003] According to the configuration of the concentrated power EMU, only the power car is equipped with the main compressor, and the power car is located at the head or tail end of the car group, so that the characteristics of the pressure distribution of the main air duct system of the car group are: distance from the wind source (that is, the main compressor) The farther away, the lower the total air pressure; especially when the control car is in the main control, the second main air cylinder of the co...
