In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Referring to fig. 2, a first embodiment of the present invention provides a flowchart of a method for preventing myopia. In this embodiment, the method of preventing myopia comprises the steps of:
step S10, acquiring current light intensity information of the target device, distance information between the user and the target device and current action information of the user;
the method for preventing myopia in this embodiment is applied to a system including a light sensor, a distance sensor, a camera, a 9-axis gyroscope sensor, a PCBA (Printed Circuit Board) motherboard, and a spectacle frame. The camera is used for detecting whether electronic equipment with a screen and the number of the electronic equipment exist in a visual field range of the camera, wherein the electronic equipment with the screen can be but is not limited to a mobile phone, a tablet computer, a television and the like, the light sensor is used for detecting the light intensity emitted by the screen of the equipment currently used by a user, the distance sensor is used for detecting the distance between the user and the equipment, the 9-axis gyroscope sensor is used for detecting the current action of the user, the PCBA mainboard is used for processing, calculating and analyzing data, and the glasses support is at least used as a carrier of the sensors, the camera and the PCBA mainboard.
Further, when the user uses the electronic equipment with the screen, the system calls the camera to shoot images in the visual field range, and identifies the type of the equipment currently used by the user according to the shot images. Further, the system calls a light sensor to detect light intensity information sent by a screen of the device currently used by the user, calls a distance sensor to detect distance information between the user and the device currently used, and calls a 9-axis gyroscope sensor to detect current action information of the user. For example: when a user lies on a bed to play a mobile phone, the system recognizes that the electronic equipment currently used by the user is the mobile phone by calling the camera, detects the light intensity emitted by the mobile phone used by the user by calling the light sensor, simultaneously calls the distance sensor to detect the distance between the user and the mobile phone, and calls the 9-axis gyroscope sensor to detect the gesture of the user currently playing the mobile phone.
Step S20, determining a target duration based on the current light intensity information, the distance information and the action information;
further, the system determines the target duration representing the maximum value of the optimal time for the user to use the current equipment according to the light intensity information sent by the screen of the current equipment used by the user, the distance information between the user and the current equipment used by the user and the current action information of the user. Specifically, the system determines a first initial duration by comparing current light intensity information with initial light intensity information of the electronic device; determining a second initial duration by comparing the distance information with recommended distance information of the electronic equipment; and determining a third initial time length by comparing the action information with the recommended action information. Further, the system calls the PCBA mainboard to calculate according to the first initial time, the second initial time and the third initial time and in combination with an adjustment coefficient determined by the light intensity information, the distance information and the action information, and determines the target time.
Step S30, detecting the use duration of the target device used by the user, determining whether the use duration is longer than the target duration, and if the use duration is longer than the target duration, generating a prompt message.
Furthermore, the system is also provided with a timing module for counting the time length of the user using the equipment, a vibration module for emitting vibration and a voice module for emitting voice prompt. Furthermore, the system detects the use duration of the current equipment used by the user through the timing module, acquires the target duration calculated and analyzed by the PCBA mainboard, and determines whether the use duration of the current equipment used by the user is greater than the target duration or not by calculating and analyzing the use duration of the current equipment used by the user and the target duration. Further, when the service life is longer than the target life, the system generates prompt information corresponding to the numerical value according to the numerical value that the service life is longer than the target life.
Further, if the duration of use is greater than the target duration, the step of generating the prompt message includes:
step S31, if the duration is longer than the target duration, determining a duration value of the duration longer than the target duration;
step S32, if the duration value is less than a preset threshold value, generating first-level prompt information;
and step S33, if the duration value is greater than or equal to a preset threshold value, generating secondary prompt information.
Further, when the fact that the service time of the current equipment used by the user is longer than the target time calculated and analyzed by the PCBA mainboard is determined, the fact that the vision and even the body health of the user are damaged when the user continues to use the electronic equipment is represented, the system generates corresponding prompt information according to the numerical value size relation between the service time and the target time, wherein the generated prompt information has at least two types, one type is vibration information, the vibration information is sent out by the glasses support through calling the vibration module, and the user is prompted that the service time of the current equipment exceeds the optimal time; the other is to generate voice reminding information, and the voice module sends out voice information to remind the user that the service time of the current equipment exceeds the optimal time, and the user is recommended to have a rest or perform outdoor activities so as to relieve eye fatigue and move bones and muscles. The prompt message can be divided into a plurality of levels, preferably two levels in the embodiment, but not limited to two levels, the intensity of the vibration message sent by the prompt message with different levels is different from the intensity of the voice prompt message, and the higher the level is, the higher the intensity of the prompt message is. The prompt messages with different forms and different levels are provided for the user, the user is reminded that the time for using the equipment is too long, and the user is advised to pause to use the equipment, so that the myopia problem caused by continuous use of the equipment by the user is prevented. Specifically, the system calculates a duration value when the use duration is longer than the target duration, if the duration value is smaller than a preset threshold value, it is indicated that the vision of the user is damaged when the electronic equipment is used under the current duration, and the system automatically generates first-level prompt information to remind the user of having a rest; if the time length value is larger than the preset threshold value, the fact that the vision of the user is greatly damaged when the electronic equipment is used under the current time length is indicated, the system automatically generates second-level prompt information, uses and warns the user, and reminds the user to move.
The embodiment provides a device and a computer readable storage medium for preventing myopia, wherein the method for preventing myopia comprises the following steps: acquiring current light intensity information of target equipment, distance information between a user and the target equipment and current action information of the user; determining target duration based on the current light intensity information, the distance information and the action information; detecting the use time of the target equipment used by the user, determining whether the use time is longer than the target time, and if the use time is longer than the target time, generating prompt information. According to the method and the device, the target duration representing the maximum value of the optimal use time is determined according to the current light intensity information of the target device, the distance information between the user and the target device and the current action information of the user, and when the use duration is longer than the target duration, prompt information is generated to provide corresponding suggestions and warnings for the user. The target duration is combined with the current light intensity information, the distance information and the action information, so that the influence of various factors on the vision of people in the current use state is accurately reflected, the frequent long-time and short-distance timely reminding of the people facing to the screen with higher brightness is realized, the excessive eye use of people is avoided, and the effective prevention of the problems of strabismus, myopia and the like is facilitated.
Further, referring to fig. 3, a second embodiment of the method for preventing myopia according to the present invention is proposed based on the first embodiment of the method for preventing myopia according to the present invention, wherein in the second embodiment, the step of determining the target duration based on the current light intensity information, the distance information, and the motion information comprises:
step S21, determining a first initial duration according to the current light intensity information;
step S22, determining a second initial time length according to the distance information;
step S23, determining a third initial time length according to the action information;
step S24, determining a target duration based on the first initial duration, the second initial duration, and the third initial duration.
Further, since different light intensities have different effects on the vision of the user, the optimal time for using the electronic device under different light intensities is different. Understandably, the light intensity of the electronic equipment is in inverse proportion to the optimal use time under a certain limit, and the stronger the light intensity is, the shorter the optimal use time is; the weaker the light intensity, the longer the optimum time. Further, the system compares the light intensity information sent by the screen of the device currently used by the user with the initial light intensity representing the default light intensity of the electronic device, and determines the first initial duration according to the proportional relation between the light intensity and the optimal duration. Further, since the influence of using the electronic device at different distances on the eyesight of the user is different, the optimal time for using the electronic device at different distances is different, and understandably, the distance for using the electronic device and the optimal use time are in a proportional relationship under a certain limit, and the longer the distance for using the electronic device is, the longer the optimal use time is; the closer the distance to use the electronic device, the shorter the optimum time. Further, the system compares the distance information of the user and the current used equipment with recommended distance information representing the optimal use distance of the electronic equipment, and determines a second initial time length according to the proportional relation between the distance of the used electronic equipment and the optimal use time length; the user uses the electronic equipment with different actions and has different influences on the eyesight of the user, so that the optimal time for the user to use the electronic equipment under different actions is different, the larger the difference between the current action of the user and the recommended action is, the shorter the corresponding optimal use time length is, and the smaller the difference between the current action of the user and the recommended action is, the longer the corresponding optimal use time length is. Further, the system compares the current action information of the user with recommended action information representing the optimal use posture of the electronic equipment, and determines a third initial duration according to the corresponding relation between the current action information of the user and the recommended action information. It can be understood that, when the user uses the electronic device, the current light intensity, the current distance, and the current action all affect the eyesight of the user, where the current light intensity affects the eyesight of the user most, and then the current distance, and the minimum is the current action. Further, the system determines the time length with the minimum value in the first initial time length, the second initial time length and the third initial time length, and determines the adjustment coefficient according to the rest two time lengths so as to balance the use time length according to a plurality of factors influencing the eyesight of the user. Further, the system determines the target time length through calculation and analysis of the PCBA mainboard according to the first initial time length, the second initial time length and the third initial time length and by combining the adjustment coefficient. Further, the step of determining the first initial duration according to the current light intensity information includes:
step S211, obtaining type information of the target equipment, and determining initial light intensity information corresponding to the type information;
step S212, comparing the initial light intensity information with the current light intensity information, and determining a proportional relationship between the initial light intensity information and the current light intensity information;
step S213, determining a first initial duration based on the proportional relationship.
Further, the system acquires type information of the target device, acquires default light intensity information of a screen corresponding to the type of the target device, and determines the default light intensity information as initial light intensity information. Further, the system compares current light intensity information, which is detected by the light sensor and is sent by a screen of the device currently used by the user, with the initial intensity information, determines a proportional relation between the initial light intensity information and the current light intensity information, and determines a first initial duration according to the proportional relation. Specifically, under the condition that the initial light intensity is fixed, the stronger the current light intensity is, the shorter the first initial duration is; the weaker the current light intensity is, the longer the first initial period is. For example, when the initial light intensity of the device used by the user is 50, the mobile phone can be used for 2 hours, and if the light intensity of the device currently used by the user is 100, it indicates that the brightness of the device currently used by the user is high, and the damage to the vision of the user is high due to long-time use, so that the use time is shortened to 1 hour; if the light intensity of the device currently used by the user is 40, the brightness of the device currently used by the user is low, and the visual damage of the user is low when the device is used at the brightness, so that the use time is prolonged to 2.2 hours.
Further, the step of determining a target duration based on the first initial duration, the second initial duration, and the third initial duration includes:
step S241, determining a minimum duration among the first initial duration, the second initial duration, and the third initial duration as a main duration;
step S242, determining an adjustment coefficient according to two other durations except the main duration in the first initial duration, the second initial duration, and the third initial duration;
and step S243, calculating the main time length and the adjusting coefficient, and determining a target time length.
Further, the system compares the numerical values of the first initial duration, the second initial duration and the third initial duration, and determines the duration with the minimum numerical value as the main duration. Further, the system determines an adjustment coefficient for balancing the main time length according to the other two time lengths except the main time length in the first initial time length, the second initial time length and the third initial time length, and specifically, determines the adjustment coefficient by taking a ratio of the time length with a large influence on the vision of the user to the time length with a small influence on the vision of the user in the two time lengths. Further, the system calculates the main time length and the adjustment coefficient according to the PCBA mainboard, and determines the target time length representing the maximum value of the optimal time for the user to use the equipment. For example, when a user uses a mobile phone, if the first initial duration is 1 hour, the second initial duration is 1.5 hours, the third initial duration is 1.2 hours, and the adjustment coefficient is 1.2, the first initial duration is used as the main duration, and the adjustment coefficient is combined to perform calculation, so that the obtained target duration is 1.2 hours; if the first initial duration is 1.2 hours, the second initial duration is 1 hour, the third initial duration is 1.5 hours, and the adjustment coefficient is 0.8, the first initial duration is taken as the main duration, and the adjustment coefficient is combined for calculation, so that the obtained target duration is 0.8 hours.
According to the embodiment, a plurality of initial durations representing the most suitable duration in each state are obtained according to the current light intensity information, the distance information and the action information, the main duration and the adjustment coefficient are obtained according to the initial durations, the target duration is accurately calculated through the PCBA mainboard, the target duration representing the maximum value of the most suitable duration of the equipment used by a user is accurately calculated, the user is timely reminded, the user is prevented from excessively using the equipment, and the beneficial effect of preventing myopia is achieved.
Further, referring to fig. 4, a third embodiment of the method for preventing myopia according to the present invention is proposed based on the first embodiment or the second embodiment of the method for preventing myopia according to the present invention, wherein the step of obtaining the current light intensity information of the target device, the distance information between the user and the target device, and the current action information of the user includes:
step S40, detecting whether an electronic device exists;
step S50, if the electronic equipment exists, determining the number of the electronic equipment;
step S60, if the number of the electronic devices is one, determining the electronic device as a target device;
step S70, if the number of the electronic devices is multiple, determining a target device according to the distance between the user and the multiple electronic devices.
Further, the system calls a camera to shoot images in the visual field range of the camera, and detects whether electronic equipment with a screen, such as a mobile phone, a computer, a tablet computer and the like, exists in the images shot by the camera. Further, if the electronic equipment exists in the image shot by the detection camera, the system further detects the number of the electronic equipment in the image. Further, if the detected image is detected to have only one electronic device, the system determines the detected electronic device as the target device; and if the detected image shot by the camera has a plurality of electronic devices, determining the target device according to the distances between the user and the electronic devices.
Further, if the number of the devices is multiple, the step of determining the target device according to the distance between the user and the multiple electronic devices includes:
step S71, if the number of the detected electronic devices is multiple, detecting distances to the multiple electronic devices respectively;
step S72, determining a minimum distance among distances between the user and the plurality of electronic devices, and determining an electronic device corresponding to the minimum distance as a target device.
Furthermore, a distance measurement algorithm for measuring distance is further arranged in the system, and the distance detection between the camera and the object to be detected is realized by combining the distance measurement algorithm and the camera.

Further, when the system determines that a plurality of electronic devices exist in an image shot by the camera, distances between the user and the plurality of electronic devices are respectively measured by calling the camera and a distance measurement algorithm. Further, after the distance measurement with the plurality of electronic devices is completed, the system calculates and compares the plurality of distances, determines the electronic device corresponding to the distance with the minimum value, and takes the electronic device as the target device. For example, when a user uses a mobile phone in a place where people are more than one, and other people are playing the mobile phone, a plurality of electronic devices exist in an image shot by a camera, and at this time, it is necessary to determine the electronic device closest to the user, that is, the mobile phone used by the user, as the electronic device most harmful to the eyesight of the user.
In the embodiment, whether the electronic equipment exists in the visual field of the user and the number of the electronic equipment exists are detected, and the electronic equipment closest to the user is determined to be the target equipment. By determining the target equipment, the situation that equipment used by other people is mistakenly considered as the user to use the electronic equipment is avoided, the light intensity of the current equipment used by the user is accurately detected, the distance between the user and the current equipment used by the user is accurately detected, the optimal time for using the current equipment is calculated according to the light intensity of the current equipment used by the user and the distance between the user and the current equipment used by the user in combination with the current action of the user, the electronic equipment is prevented from being used by the user under the conditions of high light intensity, short distance and bad posture for a long time due to the fact that the user does not pay attention to the time, and the eyesight health of the user is prevented.
