Abstract

The invention provides an intelligent control method of a ventilation and air conditioning system of a rail transit station based on passenger flow. The method comprises the following steps: determining a research station, acquiring station basic data, station historical passenger flow and train data and historical meteorological data; according to the theoretical calculation method of the ventilation and air conditioning system load, the theoretical calculation value of the ventilation and air conditioning system load is obtained by using the known data. The load calculation model of ventilation and air-conditioning system based on dynamic passenger flow is constructed. The short-term forecast load of ventilation and air-conditioning system is calculated according to the model. The control strategy of ventilation and air-conditioning system is formulated, and the intelligent control method of station ventilation and air-conditioning system based on predictive control and time-varyingpassenger flow characteristics is proposed. The invention obtains passenger flow data in a short time in the future by using passenger flow prediction and passenger flow simulation technology, therebycalculating the system predicted load in a short time in the future according to the constructed model, so that the station ventilation and air conditioning control system can deal with the temperature fluctuation in the station in the short time in the future in advance.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to an intelligent control method for a ventilation and air-conditioning system of a rail transit station based on passenger flow. Background technique [0002] As the level of economic development increases, the process of urbanization continues to accelerate, and the scale of cities further expands, the demand for transportation also increases rapidly. The contradiction between urban transportation demand and supply has become a widespread problem. Compared with urban road traffic, urban rail transit has the advantages of safety, comfort, fast environmental protection, and large transport capacity. Every city vigorously develops urban rail transit to relieve the pressure on urban road traffic. However, urban rail transit system is a large energy-consuming household in a city. High energy consumption has become one of the important reasons hindering the development of urban rail transit,...
