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

Embodiment Construction

[0046] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0047] A method for controlling ventilation in a closed parking lot provided by the invention comprises the following steps:

[0048] S1. Collect the number of parked vehicles in the parking lot, parked vehicle information, temperature information, humidity information, and altitude information in the parking lot; among them, the vehicle information includes the license plate number, vehicle type, vehicle displacement, and vehicle fuel Type, initial registration date, vehicle emission standard, vehicle speed, vehicle driving time and vehicle mileage, license plate number can lock the vehicle entering and leaving the parking lot, thereby identifying the vehicle's mileage, vehicle fuel type Used to determine the target vehicle use condition correction factor θ of the target vehicle i , the vehicle's emission standard and displacement are used to determine the cylinder ...

Abstract

A ventilation control method for a closed parking lot provided by the present invention comprises the following steps: S1. collecting the number of parked vehicles in the parking lot, the information of the parked vehicles, and the temperature information, humidity information and altitude information in the parking lot; S2. Determine the evaporative emissions of parked vehicles; S3. Collect the information of vehicles entering and exiting the parking lot and driving vehicles, and determine the mileage of vehicles during driving; S4. Determine the emissions of vehicles during driving S5. according to the sum of the emission of the vehicle in the running process and the emission of the parked vehicle, find the emission-fan power comparison table, determine the working power of the fan, and control the work of the fan according to the working power of the fan; thus both can ensure parking The exhaust gas in the field can be fully discharged to ensure the health of the people in the parking lot. On the other hand, the power required by the fan can be dynamically adjusted, so that the energy required to drive the fan can be saved, which is conducive to environmental protection.

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...
