At the same time, the universality of the eye protection device can be guaranteed, and the use cost can be reduced.

The technical solutions of the present invention will be clearly and completely described below through specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Please refer to Fig. 1, a monitoring eye protection device for computer, the monitoring eye protection device includes electric eye 1, electric eye 1 is installed in the center of the top of the computer screen, so as to ensure that the electric eye can face the user directly, and it is convenient to detect the eye information for use .

Electric eye 1 comprises shell 11, and shell 11 exterior is provided with start switch 12, and shell 11 inside is provided with: scanner 13, timer 14, database 15 and alarm 16, start switch, scanner, timer, database and The alarms are all connected through the transmission circuit. Wherein, a power supply is also arranged inside the casing.

The monitoring eye protection device also includes a bracket 2 for fixing the electric eye 1. The bottom of the bracket 2 is provided with a clamping part 21. The clamping part 21 is clamped and fixed on the upper end of the computer screen. The electric eye 1 and the bracket 2 are hinged and fixed, and can realize up and down, left and right swing. In order to adjust the position of the electric eye.

The scanner 13 is disposed inside the casing 11 and partially protrudes outside the casing 11 to monitor the state of the user's eyes.

Scanner: used to monitor the state of the user's eyes in real time; a scanner is a device that uses photoelectric technology and digital processing technology to convert graphic or image information into digital signals in a scanning manner. Scanners are commonly used as peripherals to computers by capturing images and converting them into digitized input devices that the computer can display, edit, store and output. Scanners can be used as scanning objects for three-dimensional objects such as photos, text pages, drawings, art drawings, photographic negatives, film films, and even textiles, signage panels, printed board samples, etc., to extract and convert original lines, graphics, text, photos, etc. , Convert the flat object into a device that can be edited and added to the file. In the present invention, the scanner can be similar to the scanner used in daily WeChat, because the heat of various parts of the human body under infrared rays is different, so we can program to scan when the detected heat is within the heat range of the human eye.

Generally, the scanner can be an infrared scanner, specifically an HRQ-G1 infrared scanner. When in use, programming codes can be added to control as needed.

Timer: accumulatively calculates the user's eye use time, and has an automatic reset function; after the start switch 12 is turned on, the timer starts counting. In order to ensure that the user uses the eyes reasonably, the eye use time can generally be set to 1 hour, and the user will be reminded to take a break after the cumulative use time of 1 hour. When the human eyes leave the screen for a short time, the timer stops counting, and when the human eyes stare at the screen again, the timer continues to accumulate time. If the human eye is away for a long time and the scanner cannot detect the human eye, it will stop scanning, and the timer will be timed in another way (for example, the normal time is 24-hour digital system, and the human eye is 24-hour Chinese character time system), If the human eye has not been scanned for a long time, the timer will be automatically reset, and the timer will be restarted after the human eye is scanned. The timer can be an ordinary timer on the market, and there is no specific limitation.

The timer in this application refers to the article "Design and simulation of a 24-second timer based on Multisim". When the human eye is detected by the scanner, the timer is displayed with 24 digits (such as: 1, 2, etc.) , when the human eye leaves the screen, the timer receives the signal from the scanner and converts it into 24 Chinese characters (such as: one, two, etc.).

It is recommended to use software control, the idea of the main function is as follows:

if(i==0)//i=0 means that the signal from the scanner shows that the human eyes are facing the screen;

{s=s+1;

h=s/60; }//h means 24 digital timing, s is the accumulated seconds;

if(i==1)//i=1 means that the signal from the scanner shows that the human eyes are not facing the screen;

{S=S+1;

H＝H/60;}//H means 24 Chinese characters timing, S is the accumulated seconds;

From 0:00, when the computer is turned on for the first time, the timer starts counting, and when it ends at 24:00 in the evening, the timer is reset. Cycle like this.

Database: Receive information from scanners and timers, and calculate user eye parameters to determine whether the user is in the stage of eye fatigue. The database is generally a SQL Server database.

Alarm: After determining the user's eye fatigue, an alarm is issued to remind the user to pay attention. In this application, the alarm can be an audible and visual alarm or a buzzer alarm. The reminder cycle of the timer is 1 hour, and the number of times of each alarm is 3 times. Among them, the reminder period and the number of alarms can also be set by yourself, and there is no specific limit.

A distance sensor for monitoring the relative distance between the user and the screen is also integrated inside the casing, and the distance sensor is electrically connected to the database through a transmission circuit. By setting the distance sensor to detect the distance between the user and the electric eye in real time, a reasonable distance range value can be set in the database. If the distance is within the range, it will be used normally. Once the distance exceeds the set range, the data will be sent to the alarm to alarm. remind. The distance sensor may be a common sensor on the market, such as a light sensor (FTWR80, FTWR80L), and there is no limitation here.

The eye protection device also includes a dimming module (not shown), the dimming module is arranged in the casing, and the dimming module is communicated with the database through a transmission circuit. In addition, the dimming module is electrically connected to the computer display screen. When the human eyes monitored by the scanner enter the state of eye fatigue, the dimming module automatically adjusts the light of the computer screen so that it can adapt to the light when the human eyes are tired, so that even if the human eyes are tired It can also properly reduce the damage to human eyes even if you can't leave the computer at the same time. Among them, the dimming module can adopt the 57-10000012-01 model module of the Brocade brand, or the CR-153 model module of the cn-rainbow brand, etc. The specific model can be determined according to the needs of use, and there is no limitation here.

The use principle of the present invention is as follows:

After the electric eye is installed, when the user uses the computer, the start switch 12 is turned on. At this time, the timer 14 starts timing, and the scanner 13 starts to scan the condition of the user's eyes when working. During this process, if the scanner scans that the user's eyes are not in the state of staring at the computer, the timer stops counting and accumulates with this. When the accumulated time of the timer reaches 1 hour, the database 15 transmits the signal to the alarm through the transmission circuit. Device 16, siren 16 sends the alarm, reminds the user to use eye time to reach 1 hour, eye fatigue, should carry out eye rest 5～10 minutes. If the user ignores the first siren alarm, the siren will continue to alarm 3 times. When the user gets up to rest his eyes, the timer counts to zero, and when the user works with the computer again, the timer starts counting from zero again, so as to achieve the purpose of protecting the eyes with the eyes.

The invention discloses a monitoring eye protection device for a computer, which includes an electric eye installed at the center of the top of the computer screen; the electric eye includes a casing, a start switch is arranged outside the casing, and a scanner, a timer, a database and a computer are arranged inside the casing.
