AI Technical Summary
Technical Problem
The existing fume hoods cannot adapt to different experimental needs and changes in operator height, resulting in inconsistent door opening and inaccurate air extraction.
Method used
By detecting the position of the cabinet door, the opening degree is determined and the opening area of the experimental area is calculated. Based on the area, the target air extraction volume is determined. The area obstructed by the arm is obtained using an infrared detection array, and the air extraction volume is adjusted to adapt to different opening degrees and operator positions.
Benefits of technology
It enables precise control of the air extraction volume based on experimental requirements and operator location, thereby improving the air extraction accuracy of the fume hood.

Abstract
本发明公开了一种实验用的通风柜的抽气量控制方法及系统，该方法包括：当检测到需要开始进行实验时，控制柜门进行移动以将柜门移动至符合当前实验需求的位置；根据柜门所处的位置确定柜门的开度，并根据柜门的开度确定实验区的开口的面积；根据实验区的开口的面积确定通风柜当前所需的目标抽气量，并通过目标抽气量对通风柜进行抽气。本发明解决了现有技术中抽气控制不准确的问题。
