Abstract
The utility model relates to an automatic monitor for studying posture and ambient light illumination, which is mainly characterized in that a casing is provided with a light receiving hole, a display board and an indication hole, and a light sensor is installed in the light receiving hole. A timing circuit, a posture detector, an alarm circuit and a detection circuit which is connected with the light sensor and the posture detector are installed in the casing. The utility model has the advantages of simple structure, safe and convenient operation and one object with multifunction. The utility model not only can detect ambient light illumination but also can monitor and remind a user to keep correct studying posture, and the automatic monitor for posture for studying posture and ambient light illumination has timing function simultaneously, which is especially suitable for teenagers in growth period.
Description
The utility model relates to a kind of learning posture and illuminance routine.
Show according to interrelated data, remove foreign genetic element, near-sighted, bow-backed formation is many by learning posture and ambient light is bad causes.Rarely seen on the market at present a kind of photometry stationery closes, and can only be used as the testing environment illuminance, and can not monitor learning posture.Application number is 90213100.1 juvenile's learning posture and illuminance routine, though can monitor automatically learning posture and ambient light, because its posture detection device structure is comparatively complicated, performance difficulty, and, potential danger is arranged during use because it has adopted mercury.
The purpose of this utility model is to avoid above-mentioned defective and deficiency, provides a kind of structure more simple, safe and convenient to use, the learning posture of one-object-many-purposes and ambient light routine.
The novel purpose of this reality be realize like this: on shell, be provided with and be subjected to unthreaded hole, indicator hole, display board is worn the holder of band (rope), selector switch reaches adjusting and pulls (7) geometrical clamp.Be subjected to light activated element is housed in the unthreaded hole, pilot lamp is housed in the indicator hole.Timing circuit is housed, posture detection device, and the testing circuit and the warning circuit that are connected with light activated element, posture detection device in the shell.
The utility model is subjected to unthreaded hole, indicator hole, display board owing to being provided with on shell, be subjected to be equipped with in the unthreaded hole light activated element, pilot lamp is housed in the indicator hole, timing circuit, posture detection device are housed in the shell, and the testing circuit and the warning circuit that are connected with light activated element, posture detection device, so can realize detecting the academic environment illuminance by selector switch, illumination all can show too by force or too, can monitor, remind the user to keep the better learning posture again, simultaneously can timing, reach the purpose of one-object-many-purposes.Because this monitor can wear at head or chest, and the posture detection device is by conducting strip (14), is provided with the conducting strip (16) of spacing hole (18), is contained in the formation of the conducting sphere (15) in the spacing hole (18) between conducting strip (14) and (16).For improving the restriction to conducting sphere (15), conducting strip (14) also can be established spacing hole (18) adapted on spacing hole (17) and the conducting strip (16).So no matter user's health is left avertence, right avertence, still bends forward and backward, when needing only deviation greater than certain angle, the posture detection device all can detect, and can in time remind the user to note correcting learning posture.This prison device is simple in structure, and profile is small and exquisite, and safety easy to use is particularly suitable for being in the teenager of stage of development and uses.
Accompanying drawing 1 is the monitor front view, and accompanying drawing 2 is a monitor broken section left view, and accompanying drawing 3 is the monitoring circuit schematic diagram.
Below in conjunction with accompanying drawing the utility model most preferred embodiment is described: on shell (1), be provided with and be subjected to unthreaded hole (5), indicator hole (3), display board (as the timing LCD panel) (2) is worn the holder (19) of band (9), geometrical clamp (20).Be subjected to light activated element (as photoresistance) (6) is housed in the unthreaded hole (5), pilot lamp (as LED) (4) is housed in the indicator hole (3).Timing circuit (11) is housed, posture detection device (10), and testing circuit (12) that is connected with light activated element, posture detection device and warning circuit (13) in the shell.Testing circuit is by R

4As CD4011) constitute; Warning circuit is made of NS acoustics circuit and hummer HTD.In order to make the posture detection device can detect the incorrect learning posture of user's health over-tilting (as left avertence, right avertence, bend forward and backward etc.), the posture detection device is contained in the formation of the conducting sphere (15) in the spacing hole (18) between conducting strip (14) and (16) by two conducting strips (14) (16) that are provided with spacing hole (17) (18).
During use this monitor is placed tested light path environment, functional select switch (8) selects A, can detect ambient light.Light activated element (6) is when being subjected to optical radiation, and resistance changes, and its terminal voltage Vi is changed, and the variation of Vi reflects the variation of ambient light indirectly.The upper and lower limit of testing circuit (12) sensing range is set with standard light illumination.When tested illuminance exceeds allowed band, too by force or too, Sheffer stroke gate G
4Output HIGH voltage drives the luminous and warning circuit (13) of interior the pilot lamp of indicator hole (3) (4) and sends sound equipment, and the prompting user notes improving ambient lighting, when tested illumination in allowed band, Sheffer stroke gate G
4Output LOW voltage can not drive luminous and warning circuit (13) sounding of pilot lamp (4).
After correctly settling down, monitor is hung over the front with wearing band (9), clamp clothes with geometrical clamp (20), perhaps be fixed on head (as forehead) with wearing band, functional select switch selects B, can carry out the learning posture monitoring.When user's body inclination during greater than certain angle (be generally 15 degree), place that conducting sphere (15) center of gravity C is offset between conducting strip (14), (16), exceed fulcrum D, balls tumble, and connect with conducting strip (14), conducting strip (14) is connected (quite power switch closure), warning circuit work with (16) by conducting sphere (15) as a result, hummer is rung, and reminds the user to correct learning posture.After recovering correct body position, conducting sphere (15) is rolled back in the spacing hole (18) and is disconnected (being equivalent to power switch disconnects) with conducting strip (14), and warning circuit quits work.
