Description
Technical field
The utility model relates to a kind of instrument of protecting eyes, i.e. expression in the eyes monitor.
Background technology
In prior art, the three big factors that mainly contain of myopia of student: 1, writing posture is incorrect, and the reading of promptly closely writing is prone to produce kopiopia.2, ambient light is not enough, and under darker light, reading and writing is prone to produce kopiopia.3, do not note the eyes rest, promptly long-time with eye, be difficult for during kopiopia can being changed into eyes muscular fatigue, formation myopia of long duration by student's self-discovery.
The utility model content
One of the utility model purpose is to provide a kind of to above-mentioned deficiency to utilize light-operated principle to point out the writer writing posture, writes the ambient light power through monitoring to point out the writer, and utilizing prescribes a time limit controls with eye, reaches the refreshing appearance of surveying of expression in the eyes prison of protection eyes.
The technical solution of the utility model is: the expression in the eyes monitor has light-emitting hole, light-receiving hole on housing, apart from the control circuit in pilot lamp and the housing, and control circuit comprises: the infrared emission circuit, be connected with infrared transmitting tube, and be used to launch infrared ray; Infrared receiving circuit is connected with infrared receiving tube, is used to receive the infrared ray of human body reflection; Warning circuit is connected with infrared receiving circuit, is connected with musical film, and infrared receiving circuit receives behind the IR and guide alarm circuit, the warning of sounding.This programme is confirmed eye position through monitoring writer head position.When writer's head is nearer apart from desk, be mapped to facial infrared light reflection and report to the police to receiving circuit, realize monitoring.Also have the illuminance pilot lamp on the housing of this expression in the eyes monitor, control circuit also is connected to light measuring circuit, and this circuit is connected with photoresistance, and light measuring circuit is connected with above-mentioned infrared receiving circuit, warning circuit.When writing ambient light when dark, photoresistance work, guide alarm circuit and reporting to the police is realized second purpose of the present invention.Also have timing indicator on the housing of this expression in the eyes monitor, control circuit also is connected to and is used for timing delay circuit, and is connected with above-mentioned warning circuit.Setting-up time when writing, as 40 seconds, time is up promptly reported to the police, and can overtimely not learn, and reaches the purpose of protection eyes equally.The expression in the eyes implication is the meaning of eyes, spirit.
The utility model has the advantages that: these article are used for the student and prevent bathomorphic generation and development, and it can process a product separately, also can place in the lamp of study usefulness. and it is monitored with electrical principles, and performance is high and accurate, easy to use, is easy to carry about with one.This product is monitored ambient light through Writing distance and posture are monitored, and to monitoring with length between at the moment, thereby the morbidity rate that realizes can descend greatly, eliminates myopia in the prevention stage.
Description of drawings
Fig. 1 is the utility model contour structures sketch.
Fig. 2 is the utility model control circuit schematic diagram.
Embodiment
Referring to Fig. 1, on the housing of expression in the eyes monitor, be placed with transmitting aperture 1, light-receiving hole 2, timing indicator 3, illuminance pilot lamp 4, apart from pilot lamp 5, time switch 6, time switch pilot lamp 7, power light 8, power switch 9, vocal hole 10, internal battery groove 11.During use, be placed on the dead ahead of desk, apart from about 50 centimeters of head, turn on the power switch, time switch, machine begins comprehensive monitoring, and monitoring range is distance, illuminance, learning time, gets final product with the back off switch.When the student uses, close the audible alarm system on the classroom, to avoid the influence teaching.
Referring to Fig. 2, the utility model mainly is made up of infrared emission, receiving circuit, delay circuit, warning circuit four parts.The infrared emission circuit is about the oscillatory circuit of 15kHZ by the IC1-a.b component frequency; Oscillator signal is amplified by Q1 makes infrared transmitting tube L1 emission infrared ray; In order to economize on electricity, the control of the 1Hz pulse producer that this vibration receives to be made up of IC1-c.d, thus infrared light is intermittently launched.Before this device was put in desk, power valve was aimed at and is write head, when its head infrared light when desk is nearer will be reflexed to receiving circuit by face.After infrared ray receiving tube P1 received infrared ray, 7 pin of IC2 became electronegative potential by noble potential, and the luminotron L2 that then receives indication lights.The effect of VR1 is a sensitivity adjusting, and the potential change of 7 pin makes inverter ic 3-b upset be high level simultaneously, and this high level one tunnel is through D3, and R9 drives Q2, Q3 conducting; Make L3 luminous, the writer is at first sent light report to the police, the effect of C6 is after high level disappears, for driving circuit one section time-delay to be provided; Another road makes the IC3-c upset be low level, Q7 conducting through D2, R17; Through the differential of C10 and R22,, make it to send music alarm for musical film provides trigger pulse.Light measuring circuit is by photoresistance R12 monitoring ambient light among Fig. 2.When light weakens; The 1 pin current potential step-down of IC3-a, 2 pin current potentials uprise, and this high level makes L4 send light on the one hand and reports to the police; Make the music block warning of sounding on the other hand again; The effect of C9 is to postpone a period of time to make the IC3-c upset again, and purpose is accidental in order to prevent, inevitably bow or the accidental light that covers of head causes the false triggering to reporting to the police, and has only and continues can be considered to useful signal more than 5 seconds just added the above-mentioned situation of C9.Also having a kind of situation is exactly repeatedly accidental bowing or the shading meeting is constantly grown tall the current potential on the C9; Its result also can false alarm, for fear of this situation, in circuit, has added clear circuit; Form pulsing circuit by IC3-e.f; Made it conducting for Q6 provides a pulse in per 5 seconds, and went up charges accumulated to discharge C9.Delay circuit is by IC3-d and R23, and C11 forms, about about 45 minutes of delay time, and time-delay one is arrived, the Q8 conducting, L5 is luminous, and simultaneously through C12, the R26 differential triggers the musical film sounding by the QA point, reminds the user to take a momentary rest.Product function: 1, writing posture monitoring: writing posture and distance are monitored.Writing distance is defined as 30-40 centimetre.Be placed on student's learning desk front to this product, student's chest and head and this product distance be lower than qualification apart from the time send red light (L2) and report to the police, 5-10 be when the student can not recover correct body position in second, the warning of sounding again.2, ambient light monitoring: normal writing light illumination is 75 Luxs, when ambient light is lower than 50 Luxs, sends amber light (L4) and reports to the police, and in the time of can not changing ambient light about 5 seconds, the warning of sounding again.3, between at the moment, monitor: the student learns between at the moment, to be set at 40 seconds, when learning the stipulated time, sends green light (L5) earlier and reports to the police the warning of sounding again after 5 seconds.
