Problems solved by technology

[0004] However, in a specific time period of a special line, such as rush hour, the vehicle load can vary by up to 80%, resulting in a sharp increase in the compressed air consumption of the air spring, making it difficult for the traditional compressor opening control method to meet the vehicle's wind demand. need

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] The core of the present invention is to provide a compressor control method and device that can meet the air demand of the air spring when the vehicle load changes greatly.

[0025] A compressor control method, comprising:

[0026] Step S1: Obtain the total wind pressure change rate and the total wind pressure value;

[0027] Step S2: When the rate of change of the total wind pressure is within the first preset range and the value of the total wind pre...

Abstract

The invention discloses a compressor control method, comprising: obtaining the total wind pressure change rate and the total wind pressure value; when the total wind pressure change rate is within a first preset range and the total wind pressure value is within a second preset range When it is inside, control the opening of the corresponding compressor. The present invention is based on the judgment of the total air pressure value, and at the same time, according to the change rate of the total air cylinder pipe pressure value within the first preset range, the opening control of the compressor is performed, and the pressure value can be predicted in advance from the change rate of the pressure value Therefore, it is possible to predict the consumption of compressed air, start the corresponding compressor work in advance, and reserve more compressed air for the vehicle in advance, so that when the vehicle load changes greatly, the pressure change rate is accelerated and the pressure drops. Wind demand at faster times.

Description

technical field [0001] The present invention relates to the technical field of compressors, and more specifically, to a compressor control method and device. Furthermore, the present application also relates to a rail vehicle comprising the compressor control device described above. Background technique [0002] Urban rail subway trains are generally composed of multiple vehicles, and two sets of air compressors are installed for the air source of the braking system and the air spring supply. The train control system will start a single compressor or two compressors at the same time according to the pressure value of the total air cylinder, and the pressure values ​​are set according to industry standards. In normal operation, the traditional compressor opening control method can meet the operation requirements of the vehicle. [0003] The traditional control method for turning on the air compressor of subway vehicles is: when the total air pressure is lower than 7.0bar, s...
