Children eyesight protection device used for screens of computers and TV sets and realization method thereof

Abstract

The invention discloses a children eyesight protection device used for screens of computers and TV sets and a realization method thereof. The device comprises a host, and the host comprises a biokinetic sensor, a distance sensor, a signal processor, an alarming module, a data line interface, and a display screen. The detection of the biokinetic sensor and the detection of the distance sensor areadopted in a cooperated way, a distance between a living body and the host is calculated, and then whether the living body is in a set alarming range is analyzed. When the living body is in the alarming range, acoustic, optical, electric and vibrated alarming signals are transmitted according to preset alarming modes, or the signal processor of the host is used to shut down video signals input inthe TV sets, and then the TV sets cannot broadcast TV programs, and therefore the living body can be warned to stay away from the screens of the computers and the TV sets, and harms on the eyes of the living body can be reduced, and an object of protecting the children eyesight can be realized.
