Abstract

The invention discloses an air compressor regenerated airflow control system for an urban rail vehicle. The control system comprises a monitoring device for monitoring the working state of an air compressor, a regenerated airflow regulating device for regulating flow of the regenerated airflow and a processing device electrically connected with the monitoring device and the regenerated airflow regulating device. The processing device is used for acquiring the work ratio of the air compressor according to the working state, controlling the regenerated airflow regulating device to enable the flow of the regenerated airflow to be a preset flow value when the work ratio is higher than a preset work ratio, and controlling the regenerated airflow regulating device to increase the flow of the regenerated airflow when the work ratio is not higher than the preset work ratio, so that the work ratio of the air compressor is equal to the preset work ratio. With application of the control system, extra output of the air compressor is avoided, and energy consumption is reduced. The invention further discloses the urban rail vehicle comprising the air compressor regenerated airflow control system and an air compressor regenerated airflow control method for the urban rail vehicle.

Description

technical field [0001] The present invention relates to the technical field of urban rail vehicles, and more specifically, relates to a method and system for controlling the regeneration airflow of a dryer of an urban rail vehicle, and also relates to an urban rail vehicle including the above-mentioned dryer regeneration airflow control system. Background technique [0002] With the increasingly serious problems of traffic congestion, travel inconvenience, and environmental pollution, rail transit has been recognized by more and more people because of its advantages such as large transportation capacity, high punctuality, and low environmental pollution. Urban rail vehicles are an important part of rail transit. [0003] Urban rail vehicles mostly adopt the EMU model, which is grouped in units, and its air source system is also supplied with air in units, and each unit is equipped with a set of air source systems. The air source system mainly includes air compressor, main a...
