Below, with reference to the accompanying drawings, preferred embodiment of the present utility model is described in detail, wherein:
Fig. 1 shows the course of work according to display of the present utility model.
Fig. 2 shows the inside connection diagram according to display of the present utility model.
Fig. 3 shows the synoptic diagram of induction angle.
Fig. 4 shows the synoptic diagram according to the operating position of display of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is specified.Be noted that described embodiment only is for illustrative purposes, rather than to the restriction of the utility model scope.
Fig. 2 shows the inside connection diagram according to display of the present utility model.
Adopt prior art to link to each other according to display of the present utility model, comprise sight protectio switch 205, infrared distance measurement element 203 and timer 201 with main frame.Sight protectio switch 205 is embedded in the upper side frame center position of display, and this switch 205 also is a pilot lamp 205 simultaneously.Infrared distance measurement element 203 is built in display, links to each other with sight protectio switch 205, and timer 201 links to each other with infrared distance measurement element 203.In the utility model, sight protectio switch, pilot lamp are designed to key-LED unification, and are in infrared distance measurement mouth position, succinct with the maintenance display appearance, and handled easily.Power supply of the present utility model is provided by display power supply 204, and parts that comprised and relation thereof are simple.
Infrared distance measurement element 203 adopts existing passive pyroelectric infrared probe technology.Its ultimate principle and characteristic are, human body sends and gathers on the infrared induction source after infrared ray about specific wavelength 10um strengthens by your optical filter of luxuriant and rich with fragrance mud, the pyroelectricity element in infrared induction source will lose charge balance when the human infrared radiation temperature changes receiving, outwards discharge electric charge, subsequent conditioning circuit is handled the back after testing and is produced alerting signal.Because only to the human infrared radiation sensitivity, can effectively the control environment interference of background radiation of passive infrared probe.Characteristics such as that this technology has is radiationless, low-power consumption, technical feature are stable, cheap, be widely used.The utility model has utilized the distance measurement function of this technology dexterously.
Fig. 1 shows the course of work according to display of the present utility model.
After display entered duty, infrared distance measurement element 203 promptly entered duty (S100), at this moment, and pilot lamp 205 shown in green (S102); After before user 206 is sitting in display, infrared distance measurement element 203 detects the distance (being the distance between user 206 and this element) of people-display in real time, if 〉=60 centimetres of distances, then continue to detect, according to actual needs, can be set, the still shown in green (S104: not) of pilot lamp 205 interval time between adjacent twice detection.
When user 206 too near and (the S104: be that (people-＜60 centimetres of display distances and should be, 201 computing times of timer judges whether the time of being calculated surpasses preset time) during certain time apart from duration＞30 second; S106: be), timer 201 triggers pilot lamp controller 202 and changes pilot lamp 205 color state (S108), become redness and (for example flash by the green under the normal condition with certain frequency, the cycle of flashing is 2 seconds), (S110: be after infrared range finding element 203 detects 〉=60 centimetres of people-display distances and duration＞10 second; S112: be), pilot lamp controller 202 control pilot lamp 205 colors become green (S102).
In the display use, user 206 can press sight protectio switch 205 (S103 or S109) at any time, and power-supply controller of electric 204 promptly cuts off this device power supply, and close vision defencive function (S116) is pressed switch once more and can be started this function (S100); When display is deactivated state, infrared distance measurement element 203 state of deactivating, sight protectio switch 205 enters "off" state (pilot lamp 205 extinguishes).
Fig. 3 shows the synoptic diagram of induction angle.
In the utility model, the main induction targets of infrared distance measurement element 203 is incidence of human body, belongs to local induction, and the induction angle is based on vertical direction.Can suitably set the induction angle of horizontal direction and vertical direction according to actual needs.For example, can wait and set according to user's sitting height and custom, visual angle, number of users.The induction angular range of horizontal direction is 90 °～140 °, and the induction angular range of vertical direction is 15 °～30 °.For example, during less move left and right, the induction angle of horizontal direction is set to 90 ° in the user occupy the display dead ahead and uses; As same user when in use move left and right is big, the induction angle of horizontal direction is set to 140 °.When and sitting height concordant with the infrared distance measurement mouth comparatively stablized when user's horizontal line of sight, the induction angle of vertical direction was set to 15 °; When same display used by the bigger different user of sitting height difference or sole user's sitting height when changing greatly, the induction angle of vertical direction is set to 30 °.
Fig. 4 shows the synoptic diagram according to the operating position of display of the present utility model.
As shown in Figure 4, can whether suitable by the distance between the pilot lamp 205 prompting users of display center upper portion itself and display, the user can keep the distance suitable with display (for example, 〉=60 centimetre) under the prompting of pilot lamp 205.
In addition, because the suitable distance of people-display is subjected to many-sided factor affecting such as the size of eyesight, age, display and resolution, so the defined people of the utility model-display appropriate distance can be adjusted as required.
In addition, because normal the moving of user's body may cause people-display distance to shorten in " dangerous " distance range of definition at short notice, therefore, in order to reduce wrong report, the defined infrared distance measurement element of the utility model possesses the certain time-delay response time, and its length also can be adjusted as required.
In addition, under the normal condition, the color of pilot lamp is a prerequisite with the notice of dispersion user not; Under " dangerous " distance state, the color change of pilot lamp and stroboscopic note but do not cause the people nervous, dangerous to be purpose to reach the prompting user, can define as required as for using which kind of color and flashing frequency.
Although illustrated and described the utility model at exemplary embodiments, will be understood by those skilled in the art that, under the situation that does not break away from spirit and scope of the present utility model, can carry out various other change, replacement and interpolations.Therefore, the utility model should not be understood that to be limited to above-mentioned particular instance, and should be limited by claims.
