Closed type parking lot ventilation control method and system

Abstract

The invention provides a closed type parking lot ventilation control method. The control method comprises the following steps that S1, the number of parked vehicles in a parking lot, information of the parked vehicles and temperature information, humidity information and altitude information in the parking lot are collected; S2, the evaporation emission amounts of the parked vehicles are determined; S3, information of vehicles entering the parking lot and driving out of the parking lot and information of vehicles in the driving process are collected, and the driving mileages of the vehicles inthe driving process are determined; S4, the emission amounts of the vehicles in the driving process are determined; and S5, an emission amount-fan power comparison table is found according to the sumof the emission amounts of the vehicles in the driving process and the emission amounts of the parked vehicles, the working power of fans are determined, and the fans are controlled to work accordingto the fan working power. Thus, waste gas in the parking lot can be ensured to be fully discharged, and the health of personnel in the parking lot is ensured; and on the other hand, the power required by the fans can be dynamically adjusted so that the energy required for driving the fans can be saved, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to the field of parking lots, in particular to a ventilation control method and system for a closed parking lot. Background technique [0002] In modern society, in order to save the amount of land used, underground parking is generally used for parking vehicles. As the name implies, underground parking is a space opened up under the ground. This space is generally relatively airtight. Of course, in There will also be parking lots above the ground, such as parking buildings, which are also relatively closed, and these parking lots can all be closed parking lots. [0003] The air quality in these parking lots is extremely low, and what affects air quality is mainly caused by the discharge of vehicles, if good ventilation is not carried out in the parking lot, so can cause serious impact to the health of drivers and passengers, staff, prior art Among them, for the ventilation of these parking lots, fans are used to inhale fresh air...

AI Technical Summary

Problems solved by technology

[0003] The air quality in these parking lots is extremely low, and what affects air quality is mainly caused by the discharge of vehicles, if good ventilation is not carried out in the parking lot, so can cause serious impact to the health of drivers and passengers, staff, prior art Among them, for the ventilation of these parking lots, fans are used to inhale fresh air and suck out dirty air. Power work, this method has the following defects: On the one hand, constant power work, when the vehicle emissions are large, that is, when there are many vehicles in the parking lot, the exhaust gas in the parking lot cannot be fully discharged, which will still cause health problems to the human body. On the other hand, if the emission of the vehicle is small at this time, the constant power will cause waste of energy, which is not conducive to environmental protection
