Description
Technical Field
The application relates to the technical field of myopia prevention and control, in particular to a myopia prevention and control device and a control method thereof.
Background
Compared with the relative value of solar spectrum irradiance at noon, the sun-facing solar spectrum irradiance has a plurality of wave peaks in the spectrum range of 600 nm-1300 nm, red light and infrared light in the range are beneficial to human bodies, and a plurality of instruments for treating by utilizing the light in the range are available at present, such as a dermatology red light therapeutic instrument, and a fostering instrument for treating amblyopia and myopia in ophthalmic application.
The eye research institute of college of London university published the journal of 'senile medicine' with the use energy density of 8mW/cm in 2020 2 670nm, for 3 minutes in the morning, thereby increasing the cone color contrast sensitivity (ability to detect color) of the eye of a user over 40 years old by 20% of the reported evidence that red light treatment is indeed effective on the eye.
Chinese patent document CN100569200C discloses a semiconductor laser amblyopia treatment instrument, which has an emission power of 2-3 mW and can output red laser with a wavelength of 630-650 nm to irradiate the fundus to treat amblyopia. Professor of light further verifies that the use of low intensity red light and near infrared light to illuminate the fundus is beneficial to the fundus in chinese patent document CN110237432A, "a method to increase fundus blood flow and metabolic rate"; to this conclusion, professor of how to show light also published a paper "effect of repeated low intensity red light treatment on the control of myopia progression in children: clinical tests prove that the Myopia progress of Children can be effectively Controlled by irradiating the eyeground with Red laser with the entrance pupil power of 0.29mW and the wavelength of 650 nm.
Further, chinese patent document CN108474888A discloses an "optical member" which is described to prevent and control myopia by using violet light or ultraviolet light having a certain wavelength. The realization has been carried out by clinical verification of 113 recruited children in two years in ophthalmology of medical college of Japanese Qing-Yijue university, and the clinical verification result proves that the myopia prevention and control effect of purple light is equivalent to that of low-concentration atropine.
The existing universal light feeding instrument is generally double-barrel, such as "a light feeding instrument" disclosed in chinese patent document CN 215131448U; or a single cylinder, such as "a portable myopia prevention light-feeding instrument" disclosed in chinese patent document CN 216603817U; some devices are open, such as "a smart phone vision care device" disclosed in chinese patent document CN 106657479A.
The light-feeding instrument is originally used for treating amblyopia, the reason of the single-cylinder design is that amblyopia patients generally have an eye amblyopia, the single cylinder is convenient for the amblyopia patients to carry out independent treatment on the eye of the amblyopia, so the light-feeding instrument uses the single-cylinder design in the early period. The double-cylinder design is that the myopia patients mostly have myopia of two eyes, the double-cylinder is convenient for the two eyes of the patients to receive treatment at the same time, and the double-cylinder fostering instrument is also provided with a complex pupil distance adjusting device in order to adapt to different pupil distances. Whether the single-barrel spectrometer or the double-barrel spectrometer is used, the lens barrel is used for controlling the distance between the pupil of the patient and the laser diode so as to indirectly control the intensity of the laser reaching the fundus of the patient, for example, the two types of laser standards (or the one type of laser standard (the entrance pupil power of the laser standard is not more than 0.29 mW)) that the total power of the laser reaching the pupil is not more than 1mW are met, so that the fundus can not be injured while the treatment effect is achieved; the length of the prior lens barrel is generally 127mm and 230 mm. The open type light-feeding instrument has the problem that how to control the proper distance so as to achieve the treatment effect and not bring damage, and the open type light-feeding instrument is not put into practical use in the market at present.
The inventor realizes that the existing light feeding instrument with the lens barrel generally uses an edge emitting (edge emitter) laser diode with the power of about 5mW, the laser diode is adjusted to be a circular light spot with the diameter of about 10mm after passing through a light distribution lens or being added with other beam shaping devices, the pupil distance needs to be adjusted according to the actual condition of a user when the light feeding instrument is used, the circular light spot can be irradiated to human eyes, the use is inconvenient, and the comfort is poor when the light feeding instrument is used; in addition, because the conventional light instrument usually needs to be provided with a lens barrel, the volume is large, and the use is troublesome. Meanwhile, the existing light feeding instruments lack the detection of the actual distance between the user and the laser diode; the existing light-feeding instrument cannot detect and control the intensity of laser reaching human eyes, although a Laser Diode (LD) in the existing light-feeding instrument also has PD photosensitive function to detect the intensity of laser emitted by the LD, the detected intensity is only the initial emission intensity and cannot reflect the actual intensity of the laser reaching human eyes.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Example one
In this embodiment, a myopia prevention and control device is provided, as shown in fig. 1 and fig. 2, the myopia prevention and control device includes a prevention and control device body 1, the prevention and control device body 1 includes a first casing 101, a first circuit board (not shown in fig. 1 because it cannot be seen from outside inside the first casing 101) is disposed inside the first casing 101, a main control module 102 and a constant current adjusting module 103 are disposed on the first circuit board, a light emitting component 104 is disposed on the first casing 101 (which may be a front surface), a control signal input end of the constant current adjusting module 103 is electrically connected to a first control signal output end of the main control module 102, and a current output end of the constant current adjusting module 103 is electrically connected to the light emitting component 104.
The first housing 101 (which may be an upper portion of the front surface) is further provided with a distance detection sensor 105 (i.e., 1051 and 1052 exemplarily drawn in fig. 1) or a depth vision module 106, both of which may be selectively used as needed. The data output end of the distance detection sensor 105 is electrically connected with the first data input end of the main control module 102; the data output terminal of the depth vision module 106 is electrically connected to the second data input terminal of the main control module 102. The distance detection sensor 105 and the depth vision module 106 are both required to be disposed on the same surface of the first housing 101 as the light emitting assembly 104, for measuring the distance between the user's eye and the prevention and control device body 1 when the eye is treated with the laser treatment emitted by the light emitting assembly 104.
The constant current regulating module 103 is configured to output a constant current to drive the light emitting element 104 to operate. The light emitting assembly 104 emits at least one of red laser, infrared laser, violet laser and ultraviolet laser under the driving of the constant current adjusting module 103, and the laser emitted by the light emitting assembly 104 can cover both eyes of the user at the same time. Specifically, the light emitting assembly 104 may emit red laser light, infrared laser light, violet laser light, or ultraviolet laser light with a single wavelength, for example, red laser light or infrared laser light with a wavelength of 600nm to 1300nm to be emitted into the human eye; preferably, the light emitting component 104 can emit 650nm to 670nm red laser to prevent and control myopia, and the dopamine secretion of the fundus can be increased similar to the irradiation effect towards the sun; further preferably, an infrared laser having a wavelength of 650nm is used. Of course, the light emitting component 104 can emit violet or ultraviolet laser light with a wavelength of 360-400 nm to enter human eyes, and violet laser light with a wavelength of 380nm is preferably used. The light emitting component 104 can also emit laser light with multiple wavelengths simultaneously, such as red laser light and violet laser light, for example, red laser light with a wavelength of 650nm and violet laser light with a wavelength of 380nm simultaneously, that is, a combined laser light is emitted. The laser emitted by the light emitting component 104 needs to be able to cover both eyes of the user at the same time, so the laser emitted by the light emitting component 104 can be a large beam of divergent laser, and has a certain divergence angle, thereby ensuring that both eyes of the user can be reached at the same time at a certain distance.
Alternatively, the divergence angle of the laser light emitted from the light emitting assembly 104 may be 15 ° to 150 °. Preferably, the divergence angle of the emitted laser light is 120 °.
In particular, the light emitting assembly 104 may comprise at least one light emitting diode. The light assembly 104 may preferably use at least one surface light emitting diode (e.g., 2835 lamp bead); since the laser emitted by the surface light emitting diode is divergent, an additional beam shaping device is not required, and a diffusion sheet, a dodging sheet or a diffuser is mostly used without the need of the beam expansion sheet. Of course, the light emitting component 104 may also select at least one edge laser diode, and then cooperate with the beam shaping device to generate laser with a divergence angle of 15 ° to 150 °, so long as it is ensured that the laser emitted by the edge laser diode is the diverging laser after passing through the beam shaping device, and the spot diameter can cover both eyes.
In other words, if the divergence angle of the laser light emitted by the light emitting diode is too small (for example, an edge laser diode is used), the light emitting diode can be used with the beam shaping device to make the laser light emitted by the light emitting diode diverge at a sufficiently large divergence angle, so as to ensure that the laser light generated by the light emitting component 104 is a large beam of divergent light, and thus can be simultaneously irradiated to the pupils of both eyes of a person. The beam shaping device can adopt a light homogenizing sheet, a convex lens, a grating and the like for expanding beams, diffusing or homogenizing light.
The number of the light emitting diodes is not limited, as long as it is ensured that the laser light generated by the light emitting assembly 104 can be simultaneously irradiated to the pupils of both eyes of a person, and the specific number can be set according to practical situations. The laser emitted by each light emitting diode is a beam of divergent laser (the divergent laser is emitted after being shaped or directly emitted), and the divergence angle of the laser can be 15-150 degrees; the angle of the laser emitted by each light emitting diode can be adjusted according to the number and the positions of the arranged light emitting diodes. Because the light emitting component 104 emits a large beam of scattered light, the diameter of a light spot reaching human eyes can be larger than 200mm at a certain distance (such as 10 cm-30 cm), and the light spot can cover two eyes at the same time, so that the myopia prevention and control device can enable laser to irradiate two eyes at the same time without depending on a traditional lens cone; the pupil distance does not need to be adjusted, the use is very convenient, and the comfort of the user is higher.
The laser (preferably 650nm and 380 nm) used by the prevention and control device is a part of sunlight spectrum, is harmless to human bodies under proper intensity, and uses a surface light emitting diode or an edge laser diode to be matched with a beam shaping device, so that the emitted laser is diffused at an angle of 15-150 degrees, light spots can cover two eyes, the interpupillary distance does not need to be adjusted, and the prevention and control device is convenient to use.
In addition, the appearance of the light emitting component 104 can be varied, for example, it is a round shape showing the sun after adding the light homogenizing cover, it can also be a red dot of the eyebrow of a beauty girl fighter, or a ruby on a special star-moon cane for a moon hare, etc., so as to increase the use fun of children or children.
Further, a display module 107 and/or an audio processing module 108 are further disposed on the first casing 101 of the prevention and control device body 1, and the display module 107 and the audio processing module 108 are both electrically connected to the main control module 102. The display module 107 can be disposed at the lower portion of the front surface of the first casing 101, and the audio processing module 108 can be disposed at any position of the front surface of the first casing 101, or at the side surface of the first casing 101, as long as it is ensured that the user can clearly hear the sound generated by the audio processing module 108.
The display module 107 may be a common display screen or a touch display screen. When the display module 107 is a common display screen, the input end of the display module 107 is electrically connected with one output end of the main control module 102; when the display module 107 is a touch display screen, the display module 107 is in bidirectional communication with the main control module 102, and the content to be prompted by the myopia prevention and control device can be displayed through the touch display screen, and the parameter information and the like input by a user in advance can be received.
In addition, the audio processing module 108 may only include an audio output device (speaker) and a power amplifier, and may also include an audio output device, a power amplifier and an audio input device (microphone), where the audio input device may be configured to receive a voice instruction. When the audio processing module 108 comprises an audio output device and a power amplifier, the input end of the audio processing module 108 is electrically connected with one output end of the main control module 102; when the audio processing module 108 includes an audio output device, a power amplifier and an audio input device, the audio processing module 108 is connected to the main control module 102 in a two-way communication manner.
Further, the distance detection sensor 105 may specifically be a general TOF sensor or an ultrasonic sensor. Wherein, the model of the ultrasonic sensor can be HC-SRO4. The ultrasonic sensor used in the present embodiment includes two ultrasonic probes, i.e., a first ultrasonic probe 1051 and a first ultrasonic probe 1052 in fig. 1, one of which is used to transmit ultrasonic waves and the other of which is used to receive ultrasonic waves. Some ultrasonic sensors only have one ultrasonic probe, and the distance measurement effect can be achieved by adopting the ultrasonic sensor. A common TOF sensor may be a laser range sensor, an alternative common laser range sensor model number VL53L0X when a laser range sensor is employed.
In addition, the depth vision module 106 may be composed of a three-dimensional TOF sensor, a structural light module, a binocular camera or a monocular camera, etc., and additional components to assist in depth localization. Specifically, the human face can be identified through the binocular camera, the position and the size of the pupil can be identified, and the distance between the human eyes and the module can be further accurately positioned; although the monocular camera cannot directly position the distance between the human eyes and the module and obtain the size of the pupils of the human eyes, the monocular camera can also identify the human faces, and then indirectly calculates the distance between the human eyes and the module and the size of the pupils by comparing with the scale of the forehead support; three-dimensional TOF sensors (e.g., ADSD 3100) can also be used to detect depth and identify pupil size; an example of a structured light module is microsoft's Kinect three-dimensional camera. Other depth vision schemes are also contemplated, such as light field phasing, which is not always enumerated here.
Because the myopia prevention and control device provided by the application is additionally provided with the distance detection sensor 105/the depth vision module 106, the actual distance between human eyes and the prevention and control device body 1 can be measured, so that the myopia prevention and control device can be used for realizing the auxiliary control of the distance between the eyes of a user and the prevention and control device, and the emitted laser irradiates the two eyes of the user with proper illumination intensity.
Further, when the front surface of the first housing 101 is provided with the depth vision module 106, fig. 3 illustrates with a binocular camera, and the depth vision module 106 includes the first camera 1061 and the second camera 1062 at this time, and the myopia prevention and control device further includes the forehead support bracket 2, and the front of the forehead support bracket 2 is provided with the sliding table module 3, and the forehead support bracket 2 and the sliding table module 3 can be fixed on a desktop or a bottom plate through screws in actual application. The prevention and control device body 1 is fixedly arranged on the sliding table module 3, and one surface of the prevention and control device body 1, which is provided with the light-emitting component 104, faces the forehead rest support 2; the sliding table module 3 is electrically connected with the main control module 102, and the sliding table module 3 is used for driving the prevention and control device body 1 to move up and down, back and forth, or driving the prevention and control device body 1 to move up and down, back and forth, and left and right. Optionally, a control signal input end of the sliding table module 3 is electrically connected to a second control signal output end of the main control module 102, or the sliding table module 3 is in bidirectional communication with the main control module 102.
As an alternative embodiment, as shown in fig. 3, the sliding table module 3 includes a first sliding rail 301 and a second sliding rail 302, the second sliding rail 302 is fixed on the first sliding rail 301 through a first sliding block 303, and the first sliding block 303 drives the second sliding rail 302 to move back and forth along the first sliding rail 301 through a first motor 304; the control signal input terminal of the first motor 304 is electrically connected to the corresponding control signal output terminal of the main control module 102.
As shown in fig. 4, a second slide block 305 is arranged on the second slide rail 302, the prevention and control device body 1 is fixed on the second slide block 305, when the prevention and control device body 1 is fixed, one surface of the light-emitting assembly 104 arranged on the prevention and control device body 1 faces the forehead support bracket 2, and the second slide block 305 drives the prevention and control device body 1 to move up and down along the second slide rail 302 through a second motor 306; a control signal input terminal of the second motor 306 is electrically connected to a corresponding control signal output terminal of the main control module 102.
The slide table module 3 is a conventional mechanical device, and the arrangement of the first motor 304 and the second motor 306 is obvious to those skilled in the art, so that the motors are not shown in fig. 3 and 4.
Because the monocular camera cannot directly position the distance between the eyes and the monocular camera, when the depth vision module 106 is specifically a monocular camera, the distance between the eyes and the monocular camera can be determined by using the current position of the first sliding block 303 on the first sliding rail 301, and when the first sliding block 303 moves on the first sliding rail 301, the main control module 102 can automatically acquire the position of the first sliding block 303 on the first sliding rail 301 based on the bidirectional communication connection between the sliding table module 3 and the main control module 102,
the function of the existing sliding table module in the market is self-provided. Moreover, scales can be arranged on the forehead support 201 or the chin support 202 of the forehead support bracket 2, so that the size of the pupil can be indirectly identified and calculated by comparing the image acquired by the monocular camera with the scales, and the distance between the pupil and human eyes can also be calculated.
On this basis, as another alternative embodiment, as shown in fig. 5, the sliding table module 3 may include two parallel first sliding rails 301 and two parallel second sliding rails 302, where the two second sliding rails 302 are respectively fixed on the first sliding rails 301 through first sliding blocks 303, and the two first sliding blocks 303 drive the two second sliding rails 302 to move back and forth along the first sliding rails 301 through first motors 304; as shown in fig. 6, the two second slide rails 302 are respectively provided with a second slider 305, two ends of the third slide rail 307 are respectively fixedly arranged on the two second sliders 305, and the two second sliders 305 can drive the third slide rail 307 to move up and down along the two second slide rails 302 through the second motor 306; a third slide block 308 is arranged on the third slide rail 307, the prevention and control device body 1 is fixed on the third slide block 308, one surface of the prevention and control device body 1, which is provided with the light-emitting component 104, faces the forehead support bracket 2, the third slide block 308 can drive the prevention and control device body 1 to move left and right along the third slide rail 307 through a third motor, and a control signal input end of the third motor is electrically connected with a corresponding control signal output end of the main control module 102.
In other words, the concrete implementation of the sliding table module 3 is various, and the sliding table module 3 can be designed to drive the prevention and control device body 1 to move up and down and back and forth, and can also be designed to drive the prevention and control device body 1 to move up and down, back and forth and left and right, even to move in multiple directions. Of course, the concrete implementation form of the sliding table module 3 is not limited to two forms in the example of the present application.
Further, the back surface of the first casing 101 of the general prevention and control device body 1 is flat, so that the prevention and control device body 1 can be fixed to any suitable place for use, for example, fixed to a table top or a wall surface by a double-sided adhesive tape.
As a preferable application, when the distance detection sensor 105 is provided on the front surface of the first housing 101 for convenience of use, as shown in fig. 7, the magnet 4 may be provided on the back surface of the first housing 101 of the prevention and control device body 1, so that the prevention and control device body 1 can be used by being attached to any ferrous object, such as a refrigerator, or an iron sheet that has been attached to a wall surface.
As another preferable application, the lower end of the first housing 101 of the prevention and control device body 1 may be connected with one end of the connection rod 5, and the other end of the connection rod 5 may be provided with the pedestal 6.
Specifically, as shown in fig. 8, the connecting rod 5 may be a bendable tube, and the base 6 may be in the form of a clamp: the lower extreme of the first casing 101 of prevention and control device body 1 and the one end fixed connection of connecting rod 5, the other end of connecting rod 5 is provided with centre gripping formula base 6, can press from both sides this prevention and control device body 1 to any suitable place through centre gripping formula base 6 and fix, the every single move angle of regulation prevention and control device body 1 that simultaneously can be very convenient through flexible connecting rod 5.
Similarly, as shown in fig. 9, the connecting rod 5 may be an upright tube, and the base 6 may be in the form of a base similar to a table lamp that can be placed on a table: the lower extreme of the first casing 101 of prevention and control device body 1 passes through the installed part and is connected with connecting rod 5 rotation, through wrench movement prevention and control device body 1, can adjust the angle of prevention and control device body 1.
Of course, the form of the control device body 1 is not limited to the ones shown in the drawings of the present embodiment.
Further, a first light intensity sensor 109 and/or a temperature sensor 110 may also be disposed on the first housing 101; a data output end of the first light intensity sensor 109 is electrically connected with a third data input end of the main control module 102, and the first light intensity sensor 109 is used for detecting the light intensity of the laser emitted by the light emitting component 104; the data output terminal of the temperature sensor 110 is electrically connected to the fourth data input terminal of the main control module 102.
The position of the first light intensity sensor 109 is not limited to be below the light emitting assembly 104, as long as the first light intensity sensor 109 can detect the light intensity of the laser light emitted by the light emitting assembly 104 more accurately; similarly, the position of the temperature sensor 110 may be various, and may be any position on the front surface of the first casing 101, or may be arranged on the side surface of the first casing 101, as long as it is ensured that the temperature sensor 110 can accurately detect the ambient temperature. Since the temperature has an influence on the brightness curve of the light emitting assembly 104, the intensity of light emitted by the light emitting assembly 104 can be adjusted more accurately by collecting the ambient temperature.
Further, a first communication module 111 is further arranged on the first circuit board of the prevention and control device body 1, the first communication module 111 is in bidirectional communication connection with the main control module 102, and the first communication module 111 is further used for establishing communication connection with a terminal and a cloud server.
Further, the myopia prevention and control device may further include a light intensity detection device body 7, which is used in cooperation with the prevention and control device body 1, as shown in fig. 10, the light intensity detection device body 7 includes a second housing, a second light intensity sensor 701 is disposed on a front surface of the second housing, a second circuit board is disposed in the second housing, and a processor 702 and a second communication module 703 are disposed on the second circuit board;

The specific wearing mode can refer to a heart rate belt. Of course, the fixing band may be a whole elastic band fixed from the back, or two bands provided from both ends of the second housing.
Further, the first communication module 111 needs to communicate with the second communication module 703, the terminal and the cloud server at the same time, and both the first communication module 111 and the second communication module 703 may be WIFI modules or mobile communication modules (4G modules or 5G modules). When the second communication module 703 is a bluetooth module, the first communication module 111 may include a bluetooth module and a mobile communication module (or a WIFI module) at the same time, and the first communication module 111 may communicate with the second communication module 703 through the bluetooth module, and may also communicate with the terminal and the cloud server through the mobile communication module (or the WIFI module) at the same time.
In addition, the first light intensity sensor 109 and the second light intensity sensor 701 may each be of a model TSL2561.
Through the communication connection between the second communication module 703 and the first communication module 111, the processor 702 can send the actual light intensity (power reaching human eyes) of the laser emitted to human eyes, detected by the second light intensity sensor 701, to the main control module 102 in real time, and then the main control module 102 controls the display module 107 to output and display the actual light intensity, so as to display the actual light entering amount of human eyes in real time.
As an optional configuration, through the communication connection between the first communication module 111 and the terminal and the cloud server, the main control module 102 of the prevention and control device body 1 can also send the distance between the human eye and the prevention and control device body 1 detected by the distance detection sensor 105 or the depth vision module 106, the received actual light intensity of the laser emitted to the human eye, and the pre-recorded pupil diameter information of the human eye to the terminal and the cloud server, and then display the information through software on the terminal; other information or voice prompts can be displayed through the terminal. The terminal can be, but is not limited to, a smart phone, a computer, a notebook, and the like.
Certainly, the main control module 102 can also control the display module 107 to output and display the detected distance between the human eyes and the prevention and control device body 1 and the pre-entered pupil diameter information of the human eyes, so as to remind the user to adjust the distance between the user eyes and the prevention and control device body 1, so as to control the distance between the user eyes and the prevention and control device body. In addition, the main control module 102 can also control the audio processing module 108 to perform voice prompt on the distance between the human eye detected by the distance detection sensor 105 and the prevention and control device body 1, the received actual light intensity of the laser emitted to the human eye, and the pre-recorded pupil diameter information of the human eye, so that the use by the old and the children is facilitated.

In this embodiment, as shown in fig. 11, there is provided a control method of a myopia prevention and control device, which is applied to the myopia prevention and control device provided in the above embodiment, and the method includes the following steps:
step S111, when a user puts the chin on the chin rest of the forehead rest bracket and supports the forehead against the forehead rest, the main control module acquires image data acquired by the depth vision module in real time;
step S112, the main control module sends a corresponding control signal to the sliding table module to enable the sliding table module to drive the prevention and control device body to move up and down, and the prevention and control device body is controlled to stop at a target position according to the acquired image data; when the prevention and control device body is at the target position, laser emitted by the light-emitting component can irradiate the pupils of the user;
when the concrete implementation mode of the sliding table module is as shown in fig. 3, the steps are as follows: the main control module sends a corresponding control signal to the second motor, so that the second motor drives the prevention and control device body to move up and down along the second sliding rail, and the prevention and control device body is controlled to stop at a target position according to the acquired image data; when the prevention and control device body is at the target position, the laser emitted by the light-emitting component can irradiate the pupils of the user;
step S113, calculating by the main control module according to the received image data to obtain the size of the pupil of the user, and calculating in real time to obtain the actual distance between the pupil of the user and the prevention and control device body;
step S114, the main control module calculates the target distance between the pupil of the user and the prevention and control device body according to the preset target luminous intensity, the calculated pupil size of the user and the preset target entrance pupil power;
the preset entrance pupil power can be set according to actual conditions, and generally should be controlled within 0.29mW, and should not exceed 1.0mW under special conditions;
step S115, the main control module sends a corresponding control signal to the sliding table module to enable the sliding table module to drive the prevention and control device body to move back and forth, and the actual distance between the pupil of the user and the prevention and control device body is the calculated target distance between the pupil of the user and the prevention and control device body;
when the concrete implementation manner of the sliding table module is as shown in fig. 3, the steps are as follows: the main control module sends a corresponding control signal to the first motor, so that the first motor drives the second slide rail and drives the prevention and control device body to move back and forth along the first slide rail, and the actual distance between the pupil of the user and the prevention and control device body is the calculated target distance between the pupil of the user and the prevention and control device body;

That is, for some users accidentally over-close to cause the entrance pupil power to be too high, the main control module can reduce the current to reduce the light intensity, and can also actively turn off the light emitting assembly to prevent the eye power from exceeding a certain intensity, thereby protecting the human eyes from being injured. For example, the distance can be set to be less than 5cm, and the light emitting component is actively turned off.
For example, assuming that the pupil is a perfect circle, with reference to the empirical parameters used in the professor of light, the wavelength of red light emitted by the light emitting element is set to 650nm, the illuminance to the eye is about 1600lux, the measured diameter of the pupil of the human eye is 4mm, and the actual optical power (entrance pupil power) reaching the human eye is 0.29mW (class light). That is to say: the preset light irradiation intensity reaching human eyes should be 0.29 mW/(pi 0.2cm) =2.31mW/cm 2 。
Taking a certain light emitting diode as an example, the luminous flux of the label in the manual of the diode is known to be 711.6mW, and the light emitting angle is 120 degrees spherical angle.

the main control module receives the target entrance pupil power preferred by the user from the cloud server, and takes the target entrance pupil power preferred by the user as the preset target entrance pupil power.
The mode of identifying the identity information of the user can be face identification or iris identification, namely the cloud server distinguishes different clients through face identification or iris identification, and after the user is identified, the cloud server immediately calls out the eye-entering power preference information of the user and returns the eye-entering power preference information to the prevention and control device, so that the user can conveniently use the eye-entering power preference information for treatment. In this way, even if the user uses the therapeutic apparatus provided by the application in different vision care shops, the same user information can be obtained for treatment.
Further, the method also includes:
the main control module judges whether the user has a mask or not according to the received image data;

the main control module sends a corresponding control signal to the loudspeaker, so that the loudspeaker plays a voice prompt by using the sound of the cartoon figure image, and the voice prompt is used for confirming whether the user is ready to receive treatment or not; for example, play with the sound of the isatta princess "is now magic time, do you get ready";
the main control module acquires a voice instruction of a user through a microphone and judges whether the user is ready according to the voice instruction of the user;
when the main control module judges that the user is ready to receive treatment according to the voice command of the user, step S116 is executed; for example, when the user answers "ready", it can be determined that the user is ready and then the laser emission is started.
In addition, during the treatment process, voice guidance can be added through a loudspeaker to inform the user what should be seen and what attention should be paid during the treatment process.

Example four
In this embodiment, as shown in fig. 12, another control method for a myopia prevention and control device is provided, which is applied to any one of the myopia prevention and control devices in fig. 7 to 9 in the above embodiments, and a distance detection sensor is provided on the myopia prevention and control device, and the method includes the following steps:
step S121, calculating a target distance between the pupil of the user and the prevention and control device body by the main control module according to preset target luminous intensity, a preset pupil diameter of the human eye and a preset target pupil entrance power; for example, the pupil diameter may be 4mm;
step S122, the main control module sends a corresponding control signal to the display module and/or the audio processing module to enable the display module to output a target distance and/or enable the audio processing module to output a voice prompt for prompting the target distance;
step S123, the main control module obtains the actual distance between the user ' S pupil and the prevention and control device body detected by the distance detection sensor in real time, and compares the actual distance between the user ' S pupil and the prevention and control device body with the calculated target distance between the user ' S pupil and the prevention and control device body;
step S124, when the difference value between the actual distance between the pupil of the user and the prevention and control device body and the calculated target distance is larger than or equal to a preset threshold value, the main control module sends a corresponding control signal to the display module and/or the audio processing module, so that the display module and/or the audio processing module outputs a corresponding prompt to prompt the user to adjust the distance between the user and the prevention and control device body;
step S125, when the difference value between the actual distance between the pupil of the user and the body of the prevention and control device and the calculated target distance is smaller than a preset threshold value, the main control module sends a corresponding control signal to the constant current regulating module within preset irradiation time based on preset target luminous intensity, so that the constant current regulating module outputs preset standard driving current, and the light-emitting component is controlled to emit laser with the target luminous intensity;
step S126, the main control module determines whether the actual distance between the pupil of the user and the prevention and control device body is smaller than a preset distance threshold in real time, and when it is determined that the actual distance between the pupil of the user and the prevention and control device body is smaller than the preset distance threshold, the main control module sends a corresponding control signal to the constant current adjusting module, so that the constant current adjusting module suspends outputting current, thereby controlling the light emitting assembly to suspend emitting laser.
The preset threshold may be determined according to actual situations, and may be, for example, 1cm. For example, when the distance that needs to be satisfied between the human eye and the prevention and control device body is calculated to be 10cm, and the actual distance between the human eye detected by the distance detection sensor and the prevention and control device body is 9cm, the main control module can send the detected distance to the display screen, the display screen displays the detected distance, and meanwhile, the speaker is controlled to output a voice prompt for reminding the user of being too close to the distance, so that the user is reminded of being slightly far away, and therefore the actual distance between the human eye and the prevention and control device body is consistent with the calculated distance that needs to be satisfied between the human eye and the prevention and control device body, and the preset requirement for reaching the actual light intensity of the human eye is met.
Similarly, for some users with too-close distance to cause too-high entrance pupil power, the main control module can reduce the current to reduce the light intensity, and can also actively turn off the light-emitting component to prevent the eye power from exceeding a certain intensity, thereby protecting the human eyes from being injured. For example, the distance may be set to be less than 5cm, and the light emitting device is actively turned off.
By the method provided by the embodiment of the application, the distance between the human eyes and the prevention and control device body, which needs to be met, can be determined based on the preset target light intensity, the user can be reminded to control the distance, and the light intensity reaching the human eyes can be indirectly controlled through the distance, so that a good treatment effect is achieved, and the limitation of a lens barrel of a traditional light feeding instrument is eliminated.
In addition, when the user is too close to the prevention and control device body, the light-emitting assembly can be actively closed to prevent the power of the eyes from exceeding the determined intensity, so that the eyes are protected from being injured, and the safety of treatment is guaranteed.
EXAMPLE five
In one embodiment, as shown in fig. 13, there is provided a method for controlling a myopia prevention and control device, which is applied to the myopia prevention and control device in the above embodiment, and comprises the following steps:
step S131, a distance detection sensor or a depth vision module detects the distance between the human eyes and the prevention and control device body in real time and sends the detected distance information to a main control module, and pupil diameter information of the human eyes is pre-recorded in the main control module, for example, the pupil diameter can be 4mm;
step S132, the main control module calculates the target luminous intensity of the light-emitting component according to the pupil diameter of the human eyes and the detected distance, so that the light intensity of the laser reaching the human eyes is preset light intensity after the light-emitting component emits the laser with the target luminous intensity; the preset light intensity may be set according to actual conditions, and may be set to 0.29mW, for example;
step S133, the main control module calculates the current required by the light-emitting component to reach the target light-emitting intensity, and sends a corresponding control signal to the constant current regulating module within the preset irradiation time, so that the constant current regulating module outputs the required current, and the light-emitting component is controlled to emit the laser with the target light-emitting intensity;
according to a relation curve of brightness and current in a data manual of a light-emitting diode lamp bead, the current required by a light-emitting component to reach specified brightness can be calculated; the brightness and the luminous intensity are in a direct proportion relation, so that the current required for reaching the target luminous intensity can be obtained through a relation curve of the brightness and the current;
step S134, the first light intensity sensor detects the light intensity of the laser emitted by the light-emitting component in real time and sends the detected light intensity to the main control module;
step S135, the main control module compares the detected light intensity of the laser emitted by the light-emitting component with the target light intensity;
step S136, when the main control module determines that the difference value between the light intensity of the laser emitted by the light emitting component and the target light emitting intensity exceeds the preset threshold value, the main control module sends a corresponding control signal to the constant current adjusting module, so that the constant current adjusting module adjusts the output current, and the light emitting component is controlled to adjust the light intensity of the emitted laser, so that the actual light intensity of the laser emitted by the light emitting component is adjusted by using the feedback of the first light intensity sensor, and the consistency with the target light emitting intensity or the error within the preset range is further ensured.
By considering that the physique of each person is different, the size of the pupil is different, and the required light intensity is different, through the steps, the myopia prevention and control device can automatically calculate the proper luminous intensity according to the size of the pupil and the current distance, so that the laser intensity reaching the pupil is the designated intensity. If the pupil diameter is 5mm, the initial luminous intensity is suitably reduced compared to 4mm diameter at the same distance so that the intensity reaching the pupil meets the requirement of 0.29 mW. When the distance between the user and the prevention and control device body is gradually reduced, the light intensity of the laser emitted by the light emitting component is reduced.
The main control module can also consider the influence of temperature on a brightness curve in the process of controlling the constant current module to reach the specified current to adjust the light intensity of the laser emitted by the light-emitting component; namely, the ambient temperature detected by the temperature sensor in real time is received, and then the luminance curve is calculated and the current of the constant current module is controlled by integrating the temperature influence, so that the accuracy of regulating and controlling the light intensity of the light-emitting component is further improved.
Further, the method further comprises:
the second light intensity sensor detects the actual light intensity from the laser emitted by the light-emitting component to human eyes in real time and sends the detected actual light intensity from the laser to the human eyes to the processor;
the processor sends the detected actual light intensity from the laser to the human eyes to the main control module through the second communication module and the first communication module, and the main control module judges whether the detected actual light intensity from the laser to the human eyes is consistent with the preset light intensity or not, or whether the error is within the preset range;
when the main control module judges whether the detected actual light intensity of the laser to the human eyes is inconsistent with the preset light intensity or whether the error exceeds the preset range, the main control module sends a corresponding control signal to the constant current regulating module, so that the constant current regulating module regulates the output current, and the light-emitting assembly is controlled to regulate the light intensity of the emitted laser until the actual light intensity of the laser to the human eyes received by the main control module is consistent with the preset light intensity or the error is in the preset range.
The light intensity of the laser emitted by the light emitting component is controlled through the second light intensity sensor, and the eye-entering light intensity can be controlled more accurately.
Further, the method further comprises:
the main control module judges whether the distance between the human eyes and the prevention and control device body is smaller than a preset distance threshold value or not;
when the distance between the human eyes and the prevention and control device body is judged to be smaller than the preset distance threshold value, the main control module sends corresponding control signals to the constant current adjusting module, so that the constant current adjusting module suspends output current, and the light emitting assembly suspends light emitting. That is to say, when the human eye is too close to the light-emitting point, the prevention and control device body can be automatically closed, so that the human eye is prevented from being damaged.
By the control method of the myopia prevention and control device, the laser intensity of the prevention and control device body can be automatically adjusted according to the distance between the human eyes and the prevention and control device and the size of the pupils, the limitation of the lens barrel is eliminated, portability and convenience in use are achieved, and the prevention and control device can achieve a good treatment effect. The existing light-feeding instrument of a certain brand can only adjust the laser intensity in three gears, and due to the control method provided by the embodiment of the application, the laser intensity can be automatically adjusted after the distance is detected by the distance detection sensor or the depth vision module, so that more gears of the laser intensity can be adaptively adjusted, for example, more than ten gears of the laser intensity can be adaptively adjusted.
