A wind balance automatic control method and system for a spray booth

Abstract

The invention relates to an automatic wind balance control method and system for a spray booth. The method comprises steps as follows: the average wind velocity of each area of the spray booth is acquired; the opening degree of an automatic wind valve is adjusted according to the average wind velocity of each area, so that the average wind velocity of each area reaches the calibrated wind velocity; the average total wind volume is calculated according to the average wind velocity of each area; the power supply frequency of an air supply motor and an exhaust motor is progressively increased according to set values when the average total wind volume is smaller than a first wind volume threshold; the power supply frequency of the air supply motor and the exhaust motor is progressively decreased according to set values when the average total wind volume is larger than a second wind volume threshold. With the adoption of the automatic wind balance control method and system, the problems that time and labor are consumed and the production efficiency is affected due to the fact that manual testing on the wind velocity of each area and manual adjustment of the opening degree of wind valves of air supply and exhaust systems are required for wind balance of existing spray booths are solved, and the automation and production efficiency of automobile production are improved.

Description

technical field [0001] The invention relates to the technical field of automobile production, in particular to a method and system for automatic control of wind balance in a spray booth. Background technique [0002] In the painting workshop of the automobile manufacturing industry, for the wind balance control of the spray booth, the wind speed of the spray booth is mainly periodically tested manually, and then the air valve opening of the air supply and exhaust system is adjusted according to the wind speed, and the air supply and exhaust air are manually adjusted. The inverter frequency parameters of the system should be adjusted so that the wind speed in the spray booth is in the range of 0.2-0.4 meters per second. However, after several weeks or even less than a week of production and operation of the air supply and exhaust system, or when the production situation fluctuates greatly, the air balance state that has been adjusted will be broken again. Moreover, the manua...
