Intelligent Visual Acuity Protector Based on Fuzzy Control

摘要:

针对青少年长时间使用电子产品导致视力下降的问题，提出一种基于模糊控制的智能感控视力保护仪。该保护仪的控制系统综合运用了传感器技术、数字信息处理技术、模拟数据处理技术以及智能算法，实现了软硬件的结合。针对检测过程中距离和光照强度难调节的问题，引入了模糊控制算法，通过模糊控制规则来调节距离和光照，并进行了仿真实验，将采集到的光照强度和检测距离作为输入量，定时时间作为输出量，达到提醒学生的目的。对比实验结果表明，模糊控制比PID控制的定时时间增加了10.6min，相对时间增大了18.563%，能够为学生创造更良好的学习环境。

Abstract:

In view of the problem of vision loss caused by the long-term use of electronic products by teenagers, an intelligent visual acuity protection instrument based on fuzzy control is proposed. The control system of the protector combines sensor technology, digital information processing technology, analog data processing technology, and an intelligent algorithm, and realizes the combination of software and hardware. Aiming at the problem that distance and illumination intensity are difficult to adjust in the detection process, a fuzzy control algorithm is introduced. The distance and illumination are adjusted by fuzzy control rules. The simulation experiment is carried out. The collected illumination intensity and detection distance are taken as input and timing time as output quantity to remind students. The results of the comparative experiments show that the time of fuzzy control is increased by 10.6min and the relative time is 18.563% compared with PID control, which can create a better learning environment for students.
