Closed-loop control method of air-conditioning unit and diesel generator set

Abstract

The embodiment of the invention provides a closed-loop control method for an air conditioning set and a diesel generating set. The method comprises steps: inner temperature of a carriage is acquired, and whether the inner temperature meets preset temperature is determined; if the inner temperature can not meet the preset temperature, the air conditioning set is controlled to be started, and the diesel generating set is controlled to be started for providing for the air conditioning set; if the inner temperature meets the preset temperature, the air conditioning set is controlled to be stopped, and the diesel generating set is controlled to stop providing power for the air conditioning set. Thus, synchronous closed-loop control on starting and stopping of the air conditioning set and the diesel generating set is realized, the problem of energy waste caused by continuous power supply by the diesel generating set is avoided, noise generated by the diesel generating set continuously when the vehicle operates is reduced to a certain degree, and riding comfort of a person is improved.

Description

technical field [0001] Embodiments of the present invention relate to train control technology, and in particular to a closed-loop control method for an air-conditioning unit and a diesel generator set. Background technique [0002] At present, there are two forms of power supply for railway passenger cars: centralized power supply and single-vehicle power supply. The form of power supply for a single vehicle is to install a diesel power generation device on a single carriage, and the diesel power generation device installed on the vehicle itself supplies power to the AC load of the vehicle. Generally speaking, two 40kW diesel generator sets are installed at the bottom of the vehicle, one of the two diesel generator sets is used for normal power supply, and the other is used as a backup. [0003] On railway vehicles, in order to reliably control the temperature and humidity inside the carriage, to ensure the comfort of passengers or the reliability of product transportation...

Problems solved by technology

[0004] However, at present, the start and stop of the diesel generator set and the air conditioning unit are not synchronized. No matter whether the air conditioning unit is running or not, the diesel generator set is always running to ensure continuous power supply.

During the continuous operation of the diesel generator set, it will produce a lot of noise, and the continuous operation of the diesel generator set will waste a lot of fuel, resulting in a large amount of energy consumption and waste
