Abstract
The utility model discloses an eyesight protective device which comprises a detection box and a fixture. The detection box is fixedly connected with the fixture, an ultrasonic range finder, an alarm module and a control key are arranged on the detection box, a central processing unit and a power module are arranged in the detection box, and the central processing unit is respectively connected with the ultrasonic range finder, the alarm module, the control key and the power module. The eyesight protective device has the advantages that the eyesight protective device can give an alarm when the distance from the head of a user to a display of a computer is excessively short, the user is reminded of keeping a distance to the display, and accordingly the purpose of protecting eyes of the user is achieved.
Description
Technical field
The utility model relates to human eye resist technology field, relates in particular to a kind of vision protection device.
Background technology
At present, computer has become people's indispensable instrument in study, life, work, and people utilize computer greatly to improve work efficiency.But simultaneously, people use the time of computer also more and more longer every day, and owing to personal habits, sitting posture or other reason, a lot of people can not keep the distance of eyes and computer monitor well, eyes suffer damage near computer monitor because of long-term easily, cause visual impairment.
China Patent Publication No. 201829033U; open day on May 11st, 2011; the name of utility model is called Multifunctional vision protecting control device; this application case discloses a kind of Multifunctional vision protecting control device; it comprises light Acquisition Circuit, single chip machine controlling circuit, warning circuit, display circuit, perpetual calendar circuit, keyboard circuit; described light Acquisition Circuit collection signal is to single chip machine controlling circuit; single chip machine controlling circuit drives warning circuit and reports to the police, and shows the light bull bear position by display circuit.Its weak point is, this device can only be when light intensity be undesirable call user's attention, and can not be when user's eyes and computer monitor hypotelorism reminding user.
The utility model content
The purpose of this utility model is to overcome people can not keep eyes and computer monitor well when using computer distance; eyes suffer damage near computer monitor because of long-term easily; the technical matters that causes visual impairment; a kind of vision protection device is provided; it can send warning when the hypotelorism of user's head and computer monitor; call user's attention is kept at a distance, thereby reaches the purpose of protection eyes of user.
In order to address the above problem, the utility model is achieved by the following technical solutions:
A kind of vision protection device of the present utility model; comprise and detect box and anchor clamps; described detection box is fixedly connected with anchor clamps; described detection box is provided with ultrasonic range finder, alarm module and control button; be provided with CPU (central processing unit) and power module in the described detection box, described CPU (central processing unit) links to each other with power module with ultrasonic range finder, alarm module, control button respectively.
In the technical program, power module is powered to vision protection device.Vision protection device is fixed on the top of computer monitor by anchor clamps.The user can start vision protection device work by the control button.Ultrasonic range finder detects the distance between user's head and the computer monitor, and sends it to CPU (central processing unit), and CPU (central processing unit) is judged the distance value that receives.When the distance between user's head and the computer monitor greater than predefined safe distance the time, warning device is not worked; When the distance between user's head and the computer monitor less than predefined safe distance the time, the central processing unit controls alarm module is reported to the police, and call user's attention is kept at a distance, thereby reaches the purpose of protection eyes of user.
As preferably, described alarm module comprises pilot lamp, and described pilot lamp links to each other with CPU (central processing unit).When the distance between user's head and the computer monitor less than predefined safe distance the time, the pilot lamp flicker.
As preferably, described pilot lamp is for sending the light emitting diode of ruddiness and green glow.When the distance between user's head and the computer monitor less than predefined safe distance the time, pilot lamp sends ruddiness; When the distance between user's head and the computer monitor greater than predefined safe distance the time, pilot lamp sends green glow.
As preferably, described alarm module comprises speech chip and loudspeaker, and described speech chip links to each other with loudspeaker with CPU (central processing unit) respectively.When the distance between user's head and the computer monitor less than predefined safe distance the time, CPU (central processing unit) transmits control signal to speech chip, and loudspeaker sends audio alert.
As preferably, described a kind of vision protection device comprises also and is arranged on the USB interface that detects on the box that described USB interface links to each other with CPU (central processing unit).External unit can be communicated by letter with CPU (central processing unit) by USB interface, thereby makes the user carry out setting to safe distance by external unit.
The beneficial effects of the utility model are: can send warning when the hypotelorism of user's head and computer monitor, call user's attention is kept at a distance, thereby reaches the purpose of protection eyes of user.
