Description
Technical field
The utility model relates to book case, and particularly one is based on ultrasonic anti-shortsightedness student book case.
Background technology
Myopia affects the life of people, used by students during reading abnormal sitting posture or reading apart from improper be one of reason causing myopia of student, need for this reason a kind of can read a book time preventing students from nearsightedness device.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of based on hyperacoustic myopia prevention book case.
The purpose of this utility model is realized by such technical scheme, and this book case comprises book case unit and control unit; Described book case unit comprises press strip, magnet, plastic mattress, spine, housing; Ultrasonic distance-measuring sensor, inclination sensor, button, buzzer, indicator lamp, battery module that described control unit comprises control module and is connected with control module respectively.
Further, described press strip is positioned at lower housing portion, described magnet is placed in book case edge, described plastic mattress is positioned at book case corner, described spine is positioned at housing central section, described control module, battery module, inclination sensor is arranged in spine, and described button, buzzer, indicator lamp lay respectively at shell rim.
Further, described control module is singlechip microprocessor.
Further, described ultrasonic distance-measuring sensor is HC-SR04 type ultrasonic sensor, is placed in housing top edge, and has angle with housing top edge.
Further, described inclination sensor is MMA7361 inclination sensor, is placed on spine middle and upper part, can measure the angle of inclination that book case is placed.
Further, when book case keeps flat on the table or book case takes up slant setting, described ultrasonic distance-measuring sensor detects the actual range of reading person and book case, the book case angle of inclination that inclination sensor detects, and deliver in controller, calculate the gauged distance of reading, when actual range is less than gauged distance, controller drives buzzer to send the sound, to remind reading person's hypotelorism; When reading person recovers normally to read a book distance, buzzer stops sending the sound.
Owing to have employed technique scheme, the utility model has following advantage:
One of the present utility model is based on hyperacoustic Anti-shortsightedness pupil book case, owing to adopting inclination sensor, the placed angle of book case can be detected, like this when user places book case at diverse location, correspondence can to read a book more accurately gauged distance, then detect used by students during reading distance by ultrasonic sensor, when reading distance is less than reading gauged distance, the timely warning reminding of buzzer, thus pre-myopia prevention.
Accompanying drawing explanation
In order to explain the 26S Proteasome Structure and Function principle of transformation Novel book cover more clearly, enclosing corresponding schematic diagram below and being stated detailed description:

Fig. 2 is the utility model book case circuit module connection diagram.
In Fig. 1: 1, ultrasonic distance-measuring sensor; 2, buzzer; 3, indicator lamp; 4, magnet; 5, button; 6, press strip; 7, battery module; 8, spine; 9, book case housing; 10, plastic mattress; 11, control module; 12, inclination sensor.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As Fig. 1, shown in 2, the utility model implement based on ultrasonic anti-shortsightedness book case primarily of draw together book case unit and control unit composition.Described book case unit is made up of press strip 6, magnet 4, plastic mattress 10, spine 8, housing 9.Described control unit is made up of control module 11 and the ultrasonic distance-measuring sensor 1 be connected with control module 11 respectively, inclination sensor 12, button 5, buzzer 2, indicator lamp 3, battery module 7.
Described control module 11 adopts singlechip microprocessor, realizes the control to whole system, and adopt msp430f149 microcontroller, it is the singlechip microprocessor of Low Power High Performance, and its power consumption is ultralow, moderate, meets control overflow.
Described ultrasonic distance-measuring sensor 1 selects HC-SR04 type ultrasonic sensor, for detecting the reading distance of user, and this sensor low price, low in energy consumption.
Described inclination sensor 12 is MMA7361 inclination sensor, can measure the angle that book case is placed.
Indicator lamp 3 adopts dichromatic LED, when the power source is turned on, shown in green.When battery electric quantity is not enough, shown in red.User is reminded to change battery.
Described band drives buzzer 2 for detecting that reader and book case export apart from nearly alarm when controller, a pin of singlechip microprocessor drives between buzzer 10 with band has a holding wire to be connected, when micro processor leg exports high level, buzzer rings, when exporting as low level, buzzer stops ringing.
Described power module 7 mainly comprises battery and mu balanced circuit, is control module 11, and inclination sensor 12, ultrasonic distance-measuring sensor 1, buzzer 2 etc. provides stabilized power source.
Described press strip 6, for fixing books or electronic product, prevents landing.
Described button 5 runs for starting and stop book clamp control unit.
Described magnet 4 is placed in book case edge, holds upper-lower casing when closing up for book case.Book case corner plastic mattress 10 is for the protection of book case.
In conjunction with embody rule of the present utility model, the utility model is described further:
This myopia prevention book case adopts two ultrasonic sensors 1, is the reliability in order to increase range finding.Ultrasonic sensor 1 and book case housing are also fixing at angle, and all separated in time detects reading actual range, when both measuring distance, with minimum distance for reading actual range., to go out to read a book gauged distance according to the angle correspondence that inclination sensor 12 detects, when actual range of reading a book is less than gauged distance three times continuously, buzzer 2 starts to report to the police meanwhile, until detect detecting distance when being greater than predetermined distance, stop alarm.
In order to economize on electricity, if two ultrasonic distance-measuring sensors do not detect distance all continuously several times, then illustrate that book case is in unmanned using state, controller will enter resting state, wake up after separated in time, again detect, if also distance do not detected, then again enter resting state.According to the number of times entering resting state, progressively extend the time interval that dormancy is waken up.
The above is only to preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
