Abstract

The invention relates to a control circuit of a multi-function learning control device and a leaning control method, wherein the distance of a body and the device can be sensed by an ultrasonic sensing device; once the posture of the body is incorrect, a control panel controls a loudspeaker to send voice for reminding users of correcting the posture; a learning time setting button is set according to the learning plans of the users; when the learning time is up, the device sends reminding voice; the device simultaneously controls to cut off the power supply of the socket of a lamp and the lamp is off, and the user is forced to stop learning and relaxes eyes; and the incentive to nearsightedness can be effectively avoided from multiple aspects to effectively prevent nearsightedness.

Description

technical field [0001] The invention relates to a control circuit and a learning control method of a multifunctional learning control device capable of controlling learning time, correcting learning postures and preventing myopia. Background technique [0002] Students are now suffering from myopia due to various reasons, such as long continuous study time, incorrect study posture, etc. There are various products on the market, among which posture correctors are the main ones. As mentioned above, besides learning incorrect postures, there are other causes of myopia. Therefore, these products on the market cannot completely Eliminate the triggers that lead to myopia. Contents of the invention [0003] The object of the present invention is to provide a control circuit and a learning control method of a multifunctional learning control device, which can comprehensively control learning time, learning posture, etc., and effectively prevent myopia. [0004] The present inven...
