The beneficial effects of the utility model are: with respect to prior art, the utility model adopts optoelectronic switch to detect the sitting posture that the user reads display automatically, makes user and display keep suitable distance; The time of adopting time control module control user to read display, can control or adopt the mode of voice to point out the user to protect eyes automatically.
The utility model voice suggestion eyeshield module has portability, just with convenient, is fit to very much the notebook computer user.The eyeshield module is implemented environmental protection concept in limited time, the time of having a rest setting, and make display enter holding state automatically, so not only can impel user's rest eyeshield, and in the time of having a rest, save the power consumption of display.The utility model can effectively be corrected incorrect reading computer display distance, and correct the adjustment distributed reading time, and general this eyeshield display equipment of promoting the use of is of value to and improves the trend of myopia at national rapid spread.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two;
Fig. 3 is the structural representation of the utility model embodiment three;
Fig. 4 is the structural representation of the utility model embodiment four.
Embodiment
Embodiment one
As shown in Figure 1, environmental protection voice suggestion display eye protector comprises pick-up unit, control device and suggestion device, and described pick-up unit comprises optoelectronic switch E, and control device comprises triode F, and suggestion device comprises the desktop computer that has stand alone display; Described optoelectronic switch E is located on the display of desktop computer, and optoelectronic switch E is connected with the VGA video interface of triode F and display successively, and optoelectronic switch E one end connects power supply, other end ground connection.
In the present embodiment, the detection of flip-over type optoelectronic switch E is apart from 20-30cm (conforming with the normal reading distance of people), the model of triode F is 2n2222, also be connected with some current-limiting resistances in the circuit, the VGA video interface is used to add the signal line that is inserted in display, comprises two connectivity port VGA1 and VGA2.When people's reading distance is crossed when near, be triggered to the optoelectronic switch E that is installed on the computer display screen, optoelectronic switch E trigger end is high level and promotes NPN type triode F then, make the conducting of triode C-E knot, and 14 pin of VGA interface (standby signal pin) signal ground connection, display is because standby signal pin ground connection is low level relation, and display enters holding state, so just can prevent that people from reading the hypotelorism of display, to correct user's reading posture.
Embodiment two
Because notebook computer is not as computed table, display has the VGA signal line to draw, so can not use the triggering eyeshield module of embodiment one, therefore utilize the RS232 interface to cooperate optoelectronic switch to come supervisory user and display distance, and the matching program message that gives a warning.
As shown in Figure 2, described suggestion device comprises the notebook computer that has the RS232 interface, and described optoelectronic switch E is located on the display of notebook computer, and optoelectronic switch E is connected with the RS232 interface of triode F and notebook computer successively, optoelectronic switch E one end connects power supply, other end ground connection; Special-purpose prompting eyeshield driver is installed in the notebook computer.
During this notebook dedicated trigger eyeshield module operate as normal, when optoelectronic switch E by the user because of when the too near cause of display is triggered, optoelectronic switch E trigger end is high level and promotes NPN type triode F then, make the conducting of triode C-E knot, RS232 interface the 6th pin (DSR) level is drawn high.The software aspect utilizes MSCOMM control and the TIMER control of VB6.0, ceaselessly check the level of RS232 interface the 6th pin (DSR), whenever detecting high level, just utilize list to cover the concurrent responding speech of display signal, keep suitable up to user and display, so the incorrect reading posture of correcting people is had greatest help apart from 20-30cm.
Embodiment three
Because some novel notebook computer does not have the RS232 interface, adopting voice suggestion is good solution, and this module comprises that a detection distance has the flip-over type optoelectronic switch E of 20-30cm, a record playing module M, a relay G and a 10k resistance R.As shown in Figure 3, optoelectronic switch E is located on the computer monitor, and optoelectronic switch E is connected with record playing module M with relay G successively, and optoelectronic switch E one end connects power supply, other end ground connection.
During the voice suggestion eyeshield module operate as normal of present embodiment, as optoelectronic switch E by the user because of being triggered from the too near cause of display, optoelectronic switch E trigger end is high level starting relay G then, the trigger end closure is play in order, record playing module M is triggered, the voice suggestion that gives a warning simultaneously requires user and display to keep certain distance, so the incorrect reading posture of correcting people is had greatest help.
Embodiment four
As shown in Figure 4, the described control device of present embodiment comprises time control module, and this module is made up of interconnective two time relay G1, G2 and a common relay G3, and time control module is connected with the VGA video interface of display.The VGA video interface is used to add the signal line that is inserted in display, comprises two connectivity port VGA1 and VGA2.Time relay G1 and G2 are mainly used in control user's working time and the time of having a rest, and common relay G3 is as the usefulness of reposition element.
During present embodiment work, the time relay G1 work of control user job time, normally closed port closure, order connects the 14th pin closure of computer VGA interface and display, display operate as normal.After having served as 30 minutes (triggered time of time relay G1), normally closed port disconnects, make the 14th pin that connects computer VGA interface and display disconnect (holding state signal pin), display receives the holding state signal from host computer because the 14th pin disconnects like this, computer enters holding state, and the user has a rest.The normally closed port closure of time relay G1 makes the time relay G2 work of control user's time of having a rest simultaneously, and after 10 minutes (triggered time of the time relay 2), normal ported closure starts common relay simultaneously, finishes to reset excessively.The user just can every work just need to have a rest 10 minutes in 30 minutes like this, just can work on then.
