Rather than drawing according to the number, shape and size of the components in actual implementation, the types, quantities and proportions of the components in actual implementation are not limited to the illustrations, and can be changed according to the actual design requirements.

The following is an embodiment of the present invention. As shown in FIG. 1 , the device for preventing myopia and cervical spondylosis provided by the present invention comprises an embedded system front end and an operation and maintenance back end, and the embedded system front end includes a data acquisition module 1 and a main control The module 2, the warning module 3 and the power module 4; the data acquisition module 1 is connected to the main control module 2, the main control module 2 is connected to the warning module 3, and the power module 4 provides power for the device Supply and charge management; each module receives and transmits data or instructions through a data bus; the data acquisition module 1 includes a distance sensing module, a light intensity sensing module, and a micromechanical system motion sensing module; the distance sensing module For collecting the distance between the eye and the target object; the light intensity sensing module is configured to collect ambient light intensity data; the micromechanical system motion sensing module is configured to collect data of head motion and posture; the master control The module 2 is configured as an active analysis mode, and includes a storage module and an intelligent operation module. The storage module is configured to store data collected by the data acquisition module 1 and a configurable standard. Data, standard error according to. The operation and maintenance backend includes a user interface 6.

As shown in FIG. 2, the system startup flowchart of the device for preventing myopia and cervical spondylosis of the present invention comprises the following steps:

Step 100, start.

In step 101, the system automatically detects the power of the device. When the device is higher than the alarm threshold, the process proceeds to step 102, the sensor is configured, and the configuration is interrupted. When the device is lower than the alarm threshold, the device proceeds to step 103. An alert is issued, and the alert will last for a while. Then, proceeding to step 104, the user is prompted to charge the device or connect an external power source. If the user charges the device or connects the external power source according to the prompt, the process proceeds to step 102; if the user does not charge the device or connect the external power source according to the prompt, the system proceeds to step 105 to shut down.

Step 106: After the device detects the power, prompt the user to perform mode selection, and the user may select a mode suitable for himself according to his own needs, and the selectable mode includes an active analysis mode and a power saving mode.

The active analysis mode, that is, if the user selects the mode, the device collects data at a time, analyzes the collected data in real time, and if an alarm threshold is found, an alarm signal is issued.

The power saving mode, that is, if the user selects the mode, the main control module 2 of the device is in a sleep state, and waits for a sensor interrupt event to wake up the main control module 2.

As shown in FIG. 3, it is a system flowchart of the active analysis mode of the device for preventing myopia and cervical spondylosis according to the present invention, comprising the following steps:

Step 201, after the user selects the mode, the intelligent module in the main control module 2 retrieves the head motion and posture data collected by the micromechanical system motion sensing module in the acquisition module; meanwhile, the posture stored in the storage module is also retrieved. And the motion decision tree algorithm relies on and trains the data, and the intelligent module logically processes the two sets of data.

In step 203, after the above logic processing, the current usage state of the user is determined.

Step 204: If the system does not recognize the usage status of the user by the above determination, the process proceeds to step 205, and the intelligent module continuously determines the head movement and posture data of the user collected by the micromechanical system motion sensing module. Still not sure, then go to the step 206. The intelligent module continuously monitors the head motion and posture data collected by the micromechanical system motion sensing module. If the user's usage status can be determined by the user's head motion and posture data, then step 207 is entered.

Step 207, through the above processing, the usage state of the user can be determined, for example, sitting, lying on the back, lying on the side.

Step 209, after determining the usage state of the user, the intelligent module will retrieve the configurable standard data in the state from the storage module according to the determined usage state; at the same time, the intelligent module pairs the distance, the light intensity, and the micro in the acquisition module. The data collected by the mechanical system motion sensing module is logically analyzed to wait for the results.

Step 210: The intelligent module retrieves the standard error data in the storage module, and compares the calculated result with the step 209. If the result is lower than the alarm threshold, the active analysis mode is returned; if the result is higher than the alarm threshold, an alarm signal is sent to enter the alarm mode.

It is worth mentioning that the configurable standard data retrieved by the intelligent module in step 209 is updated in real time. In this way, the comparison data can be effectively and timely selected according to the current usage state of the user, so that the structure is more accurate, and the steps are as follows:

Step 202: While determining the usage status of the user in step 203, the intelligent module still determines the current usage status of the user through step 201.

Step 208: After determining the current usage state, the intelligent module retrieves the configurable standard data of the current usage state in the storage module according to the latest determined usage state, and updates the configurable standard data in step 209.

Repeat the above steps to achieve the purpose of active analysis and real-time monitoring of the device.

As shown in FIG. 4, it is a flow chart of the power saving mode of the device for preventing myopia and cervical spondylosis of the present invention. It includes the following steps:

Step 301, the distance sensing module, the light intensity sensing module, and the micro-mechanical system motion sensing module perform initial judgment according to the built-in standard, and determine whether the collected data exceeds a preset alarm threshold. Whether the current user usage status is good.

Step 302, through the above judgment, the distance sensing module, the light intensity sensing module, and the micro-mechanical system motion sensing module respectively obtain three determination results: all data is lower than the alarm threshold, and one or all of the data is higher than the alarm threshold, all data constant.

If all the data is lower than the alarm threshold, the device considers that the user is in good use and the device returns to the power saving mode.

Step 303, when one or all of the data is higher than a preset alarm threshold, one or all of the distance sensing module, the light intensity sensing module, and the micromechanical system motion sensing module are interrupted, and the wakeup main control module is issued. 2 signal.

Step 304: When the distance sensing module, the light intensity sensing module, and the micromechanical system motion sensing module collect data, the data remains unchanged for a certain period of time. The system defaults to that the user is in the same state for a long time or the user does not use the device, and the timing module in the acquisition module is interrupted, and a wake-up signal is sent to the main control module 2.

Step 305, when the main control module 2 receives the wake-up signal of step 303 and step 304, the main control module 2 wakes up, and the intelligent module analyzes the newly collected data of the acquisition module, and determines whether to issue an alarm according to the analysis result. When the structure judged again is still higher than the alarm threshold, the alarm mode is entered; if the result of the judgment meets the standard, that is, below the alarm threshold, the power saving mode is returned.

It should be pointed out that in the power saving mode, the device can still easily judge the user's use state, mainly based on the head motion and posture data collected by the micromechanical system motion sensing module. In the power saving mode, the attitude is calculated based on the gravity components of the three directions of X, Y, and Z collected by the three-axis acceleration sensor. The three gravity vectors are Ax, Ay, Az. The sum of the three vectors is A. The orientation of the user is determined by the vector A being close to the axis of the three axes X, Y, and Z.

Repeat the above process to complete the operation of the unit in the power saving mode.

FIG. 5 is a flow chart of a device alarm mode for preventing myopia and cervical spondylosis according to the present invention.

In the active analysis mode and the power saving mode of the device, the device sends an alarm and enters the alarm mode.

It is divided into the following steps:

In step 401, after receiving the alarm signal, the alarm module issues an alarm prompt. For example, one or several warning modes of sound, light, and vibration are emitted. It is worth mentioning that there are other ways for the alarm prompt of the device, such as the glasses warning mode, by attaching a liquid crystal screen with controllability transparency to the surface of the spectacle lens, and when the alarm is issued, the liquid crystal screen is energized and adjusted. Current and voltage The size controls its transparency. The main control module 2 of the device can also transmit the information of one or any combination of the text, picture and symbol of the alarm to the liquid crystal screen through the transmission bus of the electronic and electrical standard, and the alarm information can be displayed on the liquid crystal screen, or Displayed in a fixed position. There are many alarm methods, which can more effectively remind users to correct bad living and work habits in time, and fully realize the purpose of preventing myopia and cervical spondylosis.

Step 402: After the alarm prompt is issued, when the user takes correction according to the prompt, the collecting module collects the corrected data of the user, and the intelligent module performs the analysis of step 210 or step 305 on the data, and the judgment result is lower than the alarm threshold, then the method stops. Alarm, the device re-enters active analysis mode or power saving mode.

Step 403: If the user still does not correct or the user corrects after the alarm prompt is sent, the device still considers that the user is in a bad state, and then continues to alarm.

The above is the basic function of the device to realize the operation process, of course, the device can also implement other functions. The main control module 2 of the device further includes an automatic configuration module, and the user can set configurable standard data according to different conditions of the device, and is used as standard data for alarm determination. Since the standard data of the initial configuration does not necessarily meet the requirements of different users, the user can set the configurable standard data that meets his actual situation, which can make the judgment of the device more accurate and achieve better prevention. As shown in FIG. 1 , the device is further configured with a communication module 5, through which the communication module 5 can communicate with a host on which the corresponding software is installed, and the parameters of the device are changed on the host; otherwise, if the user operates the host for a long time, The device displays the alarm information on the screen through the communication module 5; in addition, the main control module 2 further includes a forced rest module. When the alarm information described above is displayed on the screen, and the user still does not correct in time, the rest module is forced. The forced rest command sent by the main control module 2 is transmitted to the host through the communication module 5, and the screen of the host will be locked or blackened, so that the user cannot continue to operate. The host is an intelligent mobile terminal, such as a smart phone, a computer, or the like.

In order to enable the user to develop a healthy life and work habits, the main control module 2 of the device is also provided with a health index evaluation module, which collects, organizes and analyzes the data collected by the acquisition module during a period of use, within the interval. The user's usage status is displayed on the screen of the host computer through the communication module 5 through the form of comments and charts, so that the user can intuitively experience his life and work habits, and can be used for reference in future life and work. In addition, The attention of the basic users is different, that is to say, for young users, attention may be paid to the prevention of vision and cervical spondylosis; for older users, only the prevention of cervical spondylosis may be concerned, so the health index evaluation module can User selection, aggregation, collation and analysis of different data. For example, users who only care about cervical spondylosis can only sort distance data and head movement and posture data to give comments or charts. For users who are concerned about vision and who are concerned about cervical spondylosis, the data collected by the distance sensing module, the light intensity sensing module and the micro-mechanical system motion sensing module are collated, summarized and analyzed to obtain accurate opinions and charts. analysis report.

Considering that the user cannot find the power supply for charging when the power of the device is too low, so that the device cannot be used, the power generation module configured by the device can charge the device by kinetic energy or solar energy.

Due to frequent alarms of the device, the user may be bored, so the main control module 2 of the device also has a function of delay alarm. When the data collected for the change is relatively slow, such as the light intensity data collected by the light intensity sensor, when it is higher than the alarm threshold, the main control module 2 immediately sends an alarm signal, and the alarm module receives the alarm signal and immediately issues an alarm prompt; Compared with the data collected more frequently, such as the distance data collected by the distance sensing module, or the data of the head motion and posture collected by the micromechanical system motion sensing module, the data is continuously detected for a certain number of times or a period of time, and the interval is integrated. The average value of the data is still higher than the alarm threshold, and the main control module 2 sends an alarm signal, and the alarm module receives the alarm signal and issues an alarm prompt.

The device further comprises a rotating clamp connected to the outside of the device. When the device is fixed on the eye or other head attachment by the rotating clamp, the direction of collecting data of the device can be effectively improved by adjusting the rotating clamp. Close to the direction of the user's line of sight, the data collected is more accurate, and ultimately accurate and reliable results.

It should be understood by those skilled in the art that the above description is only the embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalents, and improvements made within the spirit and principles of the present invention. And the like should be included in the scope of protection of the present invention.
