单片机超声波视力保护系统设计

由于人们对人才教育的器重已经达到了新的高度,压力最终都落到学生身上,导致学生的近视程度越来越高。基于此,设计提出一款超声波视力保护系统。通过设计定时芯片实现显示器实时显示当前时间,能让用户及时查看学习时间和把控解题速度;设计语音播报电路,通过主要播放声音的形式通知和提示主人适当休息;利用超声波实现用户目视距离的测量,达到距离过近语音提示效果;搭建光敏电路,在光线比较暗的情况下能实现自动开灯效果;系统还带有GSM短信通讯功能,如果孩子不听从语音提示,长时间没有调整坐姿,就会触发短信警报通知监护人。最终能让主人在保持身体健康的同时,提高学习效率,实现劳逸结合。

As people's emphasis on talent education has reached a new height,the pressure finally falls on students,resulting in an increasing degree of myopia.Based on this,an ultrasonic vision protection system is designed and proposed.A timing chip is designed to display the current time in real time;a voice broadcast circuit is designed to inform and remind the host to have a proper rest by mainly playing sound;ultrasound is used to measure the visual distance of the user,so as to achieve the voice prompt effect of close distances;a photosensitive circuit is built,which can automatically turn on the light in the case of dark light.Besides,the system also has a GSM short message communication function,which will trigger the SMS alarm to notify the guardian if the child does not follow the voice prompt and does not adjust his sitting posture for a long time,and finally,it will enable the owner to improve the learning efficiency and realize the combination of work and rest while keeping healthy.
