Smart phone forced control method based on health linkage

Abstract

The invention discloses a smart phone forced control method based on health linkage, which comprises a hardware-level timing unit for recording the use time of a mobile phone through a special chip independent of an operating system; the health monitoring unit is integrated with a heart rate and blood pressure sensor to collect user physiological data in real time; the control unit is used for dynamically triggering mobile phone locking or warning operation based on timing and health data; and the remote management unit supports a parent terminal to set a use time period and a health threshold value.

Description

Technical Field

[0001] The present invention relates to a method for forcibly controlling a smart phone based on health linkage, and belongs to the technical field of health monitoring in mobile devices. Background Art

[0002] With the continuous expansion of the functions of smart phones, the average daily usage time of users has shown a significant growth trend. In particular, the mobile phone dependence phenomenon among teenagers due to applications such as game entertainment and social media has attracted widespread attention. The existing technologies mainly intervene through the time management function at the software level. For example, tools such as screen usage time statistics and application duration limits built into the operating system. Such solutions rely on user self-discipline or manual settings by parents. The core control logic is that the software timer triggers a system pop-up reminder, or restricts the startup of specific applications after timeout. However, due to the open loopholes in the software permission system, users can reset the timing data through factory reset, flashing the firmware, or third-party tools, resulting in the management measures being ineffective.

[0003] To solve the bypassability defect of the software solution, some manufacturers have tried to introduce a hardware-level intervention mechanism. Typical solutions include integrating an irreplaceable physical timing chip in children's smart watches, and directly cutting off the device power supply when the usage time is exhausted. However, such technologies face significant obstacles when transplanted to smart phones: on the one hand, the hardware architecture of smart phones is complex, and the independent timing chip needs to be compatible with multi-level power management systems; on the other hand, adult users have higher requirements for the integrity of device functions, and rough hardware power-off will cause safety hazards such as call interruption and emergency call failure. In addition, the existing hardware solutions lack the ability to perceive the user's physiological state and cannot achieve dynamic adaptation of health risk warnings and usage strategies.

[0004] To improve the management effect in the current industry, the following three typical technical paths have emerged: 1. Biometric recognition technology: Verify the operator's identity through fingerprint or face recognition to prevent minors from using the parent account to lift restrictions. However, this solution cannot solve the problem of excessive use by authorized users themselves, and misrecognition by the sensor will result in the wrong deprivation of legitimate usage rights. 2. Cloud remote control technology: Parents remotely set the usage period through the server, and the device end receives the instruction and executes the lock. This technology is significantly affected by network latency, and instructions are easily lost in areas with unstable signals, and it cannot maintain forced management in the offline state. 3. Health data monitoring technology: Use the built-in accelerometer and distance sensor in the mobile phone to estimate the user's fatigue level, but such indirect monitoring methods have low accuracy and lack key physiological indicators such as heart rate and blood pressure, resulting in a lack of scientific basis for health intervention strategies.

[0005] The above technical route exposes the core pain points of the industry: software control is easily cracked, hardware blocking damages the core functions of devices, and there is a lack of effective linkage between health monitoring and usage restrictions. Especially in the scenario of teenagers' use, the existing solutions can neither build an irreversible mandatory restriction mechanism at the system bottom layer nor implement precise intervention based on real-time physiological data, resulting in the continuous deterioration of problems such as vision damage and cervical spine lesions caused by mobile phone addiction.

[0006] Therefore, how to build an unavoidable usage restriction mechanism while ensuring the integrity of smartphone functions and achieve the dynamic linkage between health monitoring data and control strategies has become the technical problem to be solved by this invention. Summary of the Invention

[0007] This invention provides a mandatory control method for smartphones based on health linkage, and its main purpose is to solve the problems of crackability of software control, destructiveness of hardware blocking functions, and disconnection between health data and application restrictions.

[0008] To achieve the above purpose, a mandatory control method for smartphones based on health linkage provided by this invention includes the following steps: Step 1, the hardware-level timing unit independent of the operating system records the mobile phone usage time in real time. The hardware-level timing unit realizes the timing function through an independent circuit, and the operating state of the timing unit is not affected by the restart or reset operation of the operating system; Step 2, the heart rate data and blood pressure data of the user are collected in real time through the heart rate sensor and blood pressure sensor integrated in the mobile phone, and the heart rate data and blood pressure data are input into the control unit; Step 3, the control unit generates a health score according to the heart rate data and blood pressure data. The calculation method of the health score is: multiply the real-time heart rate data by the first weight coefficient, multiply the real-time blood pressure data by the second weight coefficient, and use the weighted sum of the two as the health score; Step 4, when the cumulative usage time recorded by the hardware-level timing unit exceeds the preset time threshold, or the health score exceeds the preset health threshold, the control unit triggers a mandatory restriction operation: If the cumulative usage time exceeds the preset time threshold, lock the mobile phone screen until the preset unlocking condition is met; If the health score exceeds the preset health threshold, perform reminder operations, restriction operations, and mandatory locking operations in sequence according to the over-limit level of the health score; Step 5, receive instructions from the remote management unit. The remote management unit allows setting or modifying the preset time threshold, preset health threshold, first weight coefficient, and second weight coefficient, and retains the emergency unlocking permission after the control unit triggers the mandatory locking operation. The execution of the emergency unlocking permission requires synchronous verification that the current health score is lower than the preset health threshold.

[0009] Preferably, in step 1, the hardware-level timing unit includes an independent clock chip and a tamper-proof memory. The tamper-proof memory stores the cumulative usage time data, and the read and write operations of the tamper-proof memory only respond to the encrypted instructions issued by the control unit.

[0010] Preferably, in step 3, the first weight coefficient and the second weight coefficient are dynamically adjusted according to the user's age: when the user's age is less than 18 years old, the first weight coefficient is 0.7 and the second weight coefficient is 0.3; when the user's age is greater than or equal to 18 years old, the first weight coefficient is 0.5 and the second weight coefficient is 0.5.

[0011] Preferably, the trigger logic of the forced restriction operation in step 4 includes: when the health score exceeds the first health threshold but does not exceed the second health threshold, a reminder operation is performed, and the reminder operation includes reducing the screen brightness and popping up a health warning interface; when the health score exceeds the second health threshold but does not exceed the third health threshold, a restriction operation is performed, and the restriction operation includes closing non-essential applications and restricting the screen refresh rate; when the health score exceeds the third health threshold, a forced lock operation is performed and a health report is generated.

[0012] Preferably, the execution of the emergency unlocking permission in step 5 includes the following conditions: when an emergency unlocking request is triggered, the control unit collects the current heart rate data and blood pressure data in real time and generates a temporary health score; if the temporary health score is lower than the preset health threshold, temporary unlocking is allowed and an emergency timer is started. The emergency timer is independent of the hardware-level timing unit, and the cumulative time is included in the total usage time of the hardware-level timing unit; if the temporary health score is higher than the preset health threshold, the unlocking request is rejected and a forced lock operation is started.

[0013] Preferably, the calculation of the health score in step 3 further includes introducing an environmental parameter correction factor. The environmental parameters include the environmental light intensity and the blue light radiation intensity of the mobile phone screen. The correction factor is used for dynamic compensation calculation of the health score.

[0014] Preferably, the preset unlocking conditions in step 4 include: the unlocking condition after the cumulative usage time exceeds the preset time threshold is: reaching the preset time node of the next day zero o'clock; the unlocking condition after the health score exceeds the limit is: the user continuously maintains the health score lower than the preset health threshold for a preset duration in the locked state.

[0015] Preferably, the collection of blood pressure data in step 2 is realized by combining the mobile phone camera with the photoplethysmogram algorithm, specifically including: capturing the blood volume change signal of the user's fingertip through the camera; inputting the signal into a preset blood pressure calculation model and outputting the real-time blood pressure data.

[0016] Preferably, in step 5, a two-way encrypted communication protocol is adopted between the remote management unit and the control unit, and the operation instructions of the remote management unit need to be verified by biometric authentication or dynamic verification code.

[0017] Preferably, the forced locking operation in step 4 includes cutting off the power supply to the screen and disabling the touch function, and the forced locking operation can be released only by authorization of the remote management unit or by satisfying a preset unlocking condition.

[0018] Compared with the problems described in the background technology, the beneficial effects of the present invention are: 1. Through the decoupling design of the hardware-level timing unit and the operating system (such as independent timing chips and dedicated circuits), the possibility of users removing restrictions through software means such as system reset and password cracking is avoided. When the cumulative usage time reaches the threshold, the module directly sends a hardware-level blocking signal to the power management chip to implement physical-level usage restrictions, which is particularly effective in solving the behavioral pain points of malicious cracking by young people.

[0019] 2. The heart rate / blood pressure sensor data stream is algorithmically integrated with the time control strategy (health score = heart rate × 0.6 + blood pressure × 0.4). When the system detects that the user is in a state of anxiety (heart rate > 120bpm) or hypertension (systolic blood pressure > 140mmHg), the system automatically triggers the health lock mechanism: it not only immediately shortens the remaining usage time, but also dynamically pushes eye protection mode adjustment instructions (such as reducing screen blue light and forcibly turning on the distance sensor), achieving a usage effect from passive restriction to active health intervention.

[0020] 3. The parental control module builds a dual verification channel through the trusted execution environment (TEE). While supporting remote setting of time periods / application whitelists, it adds an emergency medical response interface. When the system detects abnormal health data three times in a row, it not only pushes a vibration alarm to the user, but also sends positioning information and maps of surrounding hospitals to the parent, forming a full-chain protection system of mandatory restrictions-health warnings-medical assistance.

[0021] 4. When the user attempts to forcibly dismantle the timing module, the system automatically activates the backup monitoring strategy - calling the front camera to analyze facial blood oxygen characteristics, combining gyroscope data to identify abnormal limb movements (such as bowing the head for a long time), and ensuring the continued effectiveness of mandatory control through multiple technical guarantees.

[0024] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] An embodiment of the present application provides a method for forcibly controlling a smart phone based on health linkage, including the following steps: Step 1, the hardware-level timing unit independent of the operating system records the mobile phone usage time in real time. The hardware-level timing unit realizes the timing function through an independent circuit, and the operating state of the timing unit is not affected by the restart or reset operation of the operating system; Step 2, the heart rate sensor and blood pressure sensor integrated in the mobile phone collect the user's heart rate data and blood pressure data in real time, and input the heart rate data and blood pressure data into the control unit; Step 3, the control unit generates a health score according to the heart rate data and blood pressure data. The calculation method of the health score is: multiplying the real-time heart rate data by the first weight coefficient, multiplying the real-time blood pressure data by the second weight coefficient, and taking the weighted sum of the two as the health score; Step 4, when the cumulative usage time recorded by the hardware-level timing unit exceeds the preset time threshold, or the health score exceeds the preset health threshold, the control unit triggers a forced restriction operation: If the cumulative usage time exceeds the preset time threshold, the mobile phone screen is locked until the preset unlocking condition is met; If the health score exceeds the preset health threshold, reminder operations, restriction operations, and forced locking operations are sequentially executed according to the over-limit level of the health score; Step 5, receive instructions from the remote management unit. The remote management unit allows setting or modifying the preset time threshold, preset health threshold, first weight coefficient, and second weight coefficient, and retains the emergency unlocking permission after the control unit triggers the forced locking operation. The execution of the emergency unlocking permission requires synchronous verification of whether the current health score is lower than the preset health threshold.

[0026] Preferably, in step 1, the hardware-level timing unit includes an independent clock chip and a tamper-proof memory. The tamper-proof memory stores the cumulative usage time data, and the read and write operations of the tamper-proof memory only respond to the encrypted instructions issued by the control unit.

[0027] Preferably, in step 3, the first weight coefficient and the second weight coefficient are dynamically adjusted according to the user's age: when the user's age is less than 18 years old, the first weight coefficient is 0.7 and the second weight coefficient is 0.3; when the user's age is greater than or equal to 18 years old, the first weight coefficient is 0.5 and the second weight coefficient is 0.5.

[0028] Preferably, the triggering logic of the forced restriction operation in step 4 includes: when the health score exceeds the first health threshold but does not exceed the second health threshold, performing a reminder operation, and the reminder operation includes lowering the screen brightness and popping up a health warning interface; when the health score exceeds the second health threshold but does not exceed the third health threshold, performing a restriction operation, and the restriction operation includes closing non-essential applications and limiting the screen refresh rate; when the health score exceeds the third health threshold, performing a forced lock operation and generating a health report.

[0029] Preferably, the execution of the emergency unlocking authority in step 5 includes the following conditions: when the emergency unlocking request is triggered, the control unit collects the current heart rate data and blood pressure data in real time and generates a temporary health score; if the temporary health score is lower than the preset health threshold, temporary unlocking is allowed and the emergency timer is started. The emergency timer is independent of the hardware-level timing unit, and the accumulated time is included in the total usage time of the hardware-level timing unit; if the temporary health score is higher than the preset health threshold, the unlocking request is rejected and a forced locking operation is started.

[0030] Preferably, the calculation of the health score in step 3 also includes introducing an environmental parameter correction factor, where the environmental parameters include ambient light intensity and blue light radiation intensity of the mobile phone screen, and the correction factor is used to perform dynamic compensation calculation on the health score.

[0031] Preferably, the preset unlocking conditions in step 4 include: the unlocking condition after the cumulative usage time exceeds the preset time threshold is: reaching the preset time node of midnight the next day; the unlocking condition after the health score exceeds the limit is: the user continues to maintain the health score below the preset health threshold for a preset period of time in the locked state.

[0032] Preferably, the collection of blood pressure data in step 2 is achieved through a mobile phone camera combined with a photoplethysmography algorithm, specifically including: capturing the blood volume change signal of the user's fingertips through the camera; inputting the signal into a preset blood pressure calculation model, and outputting real-time blood pressure data.

[0033] Preferably, in step 5, a two-way encrypted communication protocol is adopted between the remote management unit and the control unit, and the operation instructions of the remote management unit need to be verified by biometric authentication or dynamic verification code.

[0034] Preferably, the forced locking operation in step 4 includes cutting off the power supply to the screen and disabling the touch function, and the forced locking operation can be released only by authorization of the remote management unit or by satisfying a preset unlocking condition.

[0035] See also Figure 1This is the flowchart of the forced control method for smartphones based on health linkage. The process starts with the startup (start the healthy phone usage mode) step, after which the system starts timing and monitors health data. Next, the system determines whether the usage time has been exceeded or there is a health anomaly. If the result is no, the health data will be continuously monitored in a loop. If the result is yes, the system further determines whether the usage time has been exceeded. If the result of exceeding the usage time is yes, the phone will be locked until the next day and a time reminder will be displayed, and the process will finally end. If the result of exceeding the usage time is no, it will determine whether there is an anomaly in the health data. If the result of the health data anomaly is yes, a reminder will be issued, usage will be restricted, and a health reminder will be displayed, and the process will finally end.

[0036] Example 1: In a typical application scenario, regarding the smartphone usage problem of the adolescent group, this example demonstrates how to implement the forced control method based on health linkage in a smartphone to solve the problems in the prior art such as the easy bypass of software control, the possible damage to device functions by hardware intervention, and the lack of effective linkage between health data and usage restrictions.

[0037] Suppose in a certain family, the parents decide to manage their children's smartphone usage reasonably to prevent health problems caused by overuse. The smartphones in this family have integrated the technical solution proposed by the present invention. The phone is equipped with a hardware-level timing unit and a health monitoring unit, which can record and analyze the usage time and physiological data in real time. Specifically, the parents set the following parameters through the remote management system: the daily usage duration does not exceed 3 hours, and a restriction operation is triggered when the heart rate exceeds 120 bpm or the blood pressure exceeds 140 mmHg.

[0038] One day, when the child was using the phone for entertainment and social activities as usual and had been using it for 2 hours, the phone system started to automatically monitor the usage time according to the hardware-level timing unit. At this time, the control unit detected that the usage time was about to reach the set 3-hour threshold and triggered the health monitoring unit to analyze the user's heart rate and blood pressure data. The system detected that the child's heart rate began to rise gradually, reaching an overactive state, and the blood pressure was also approaching the set high health threshold. This change in health data directly prompted the control unit to intervene according to the health score, further shortening the remaining usage time.

[0039] When the child continues to use the phone, the screen brightness automatically decreases, and the system pops up a health warning interface to remind the user to take a rest and recommends adopting eye protection mode. At this time, the system will also automatically push eye protection mode adjustment instructions based on the health score, reduce screen blue light and turn on the distance sensor to reduce eye fatigue. During this process, although the user saw the health warning interface, he did not immediately interrupt the use of the phone. Instead, he felt the change in screen brightness and the automatically enabled eye protection mode in the next half hour, gradually reducing his dependence on the phone.

[0040] However, when the user continued to ignore the health warning and continued to use the phone, the system found after a period of health data analysis that the child's health score exceeded the second health threshold, and both the heart rate and blood pressure were at a high warning level. At this time, the mobile phone system no longer intervened simply through reminder operations, but took more stringent restrictions: the phone screen was automatically locked and the touch function was disabled. This measure can fundamentally prevent users from bypassing restrictions through any loopholes or cracking methods in the operating system, and avoid users from removing restrictions by restarting the device, restoring factory settings, etc.

[0041] In order to further ensure the accuracy of health intervention, the system combines environmental parameters such as ambient light intensity and screen blue light radiation intensity, and dynamically compensates the calculation of health scores through correction factors to avoid misleading external environmental factors on user health. This effectively improves the scientificity and accuracy of the system.

[0042] On the parent side, parents can view their children's usage time and health status in real time through the remote management system. At this time, parents find that their children have not followed the healthy usage rules for a long time, and the system has automatically locked the phone screen and recorded the health data. Parents can start the unlocking procedure through the remote system in an emergency, provided that the child's health score is below the preset health threshold, which can not only protect the child's health, but also ensure that the phone's functions are not damaged.

[0043] The application effect of this embodiment significantly improves the accuracy and effectiveness of smartphone management. In the absence of this technical solution, parents may only be able to manually set the usage period through software tools, and users can bypass the control by cracking the software restrictions. After adopting this technical solution, the system realizes dynamic intervention based on health data, and ensures the non-bypassability of management measures through hardware-level timing units, avoiding users from cracking restrictions through software means. Especially in the youth group, the close linkage between health monitoring and usage restrictions not only prevents excessive use, but also plays an effective role in health intervention, greatly reducing the occurrence of problems such as excessive eye use and cervical spine damage.

[0044] In addition, through the integration of health data, the system can not only proactively conduct health interventions, but also provide real-time health warnings to parents, and offer rescue support in case of emergencies by combining with the emergency medical response interface. When the system detects abnormal health data three times in a row, it will automatically send an alarm message to the parents, including location information and a map link to the nearby hospital, forming a complete health protection chain.

[0045] Embodiment 2: In this embodiment, based on the actual mobile phone usage scenario of a high school student, it shows how to effectively manage mobile phone usage through the mandatory healthy mobile phone system of the present invention, ensuring that teenagers can enjoy the convenience brought by technology while being reasonably protected in terms of health during the process of using mobile phones.

[0046] Suppose Xiaoming is a high school student. In his daily life, he often uses his mobile phone due to heavy schoolwork and interactions on social media, often using it for several hours at a time, resulting in eye fatigue and neck soreness. To address this excessive dependence on mobile phones, Xiaoming's parents decided to enable the healthy mobile phone system of the present invention for him. The system is installed on Xiaoming's mobile phone, and his parents set a maximum daily usage time of 2 hours. When the heart rate exceeds 120 bpm, the system will automatically remind and restrict mobile phone usage.

[0047] In a typical application scenario, Xiaoming, as usual, starts playing games and watching social media videos. As time goes by, the hardware-level timing unit of the mobile phone records Xiaoming's usage time in real time. When Xiaoming has played for 1 hour and 30 minutes, the system collects Xiaoming's heart rate data through the health monitoring unit. At this time, Xiaoming's heart rate has exceeded the set warning threshold (120 bpm). The control unit then triggers the health scoring model, combines the heart rate and blood pressure data, calculates Xiaoming's health score, and makes a restriction operation based on this score. The system prompts Xiaoming by saying: "Your heart rate has exceeded the standard. Please pause using the mobile phone and take a rest." Although Xiaoming was reminded to pay attention to rest, he did not stop immediately and still continued to use the mobile phone for social interaction. The system detected that as time passed, Xiaoming's heart rate continued to be at a high level, and his health score continued to rise, exceeding the health threshold. The system immediately entered the next operation: forced restriction. At this time, the screen brightness of the mobile phone automatically decreased to the lowest level, the functions of the mobile phone were restricted, the game was paused, and other applications were automatically closed. In this way, the system forcibly restricted Xiaoming's mobile phone usage and prevented him from further aggravating his health problems.

[0048] During this process, the remote management function of parents also plays a key role. Xiaoming's parents can view Xiaoming's mobile phone usage status and health data in real time through another device. When the system triggers a forced restriction, a warning message immediately pops up on the parents' remote device, showing Xiaoming's health status and time usage. At this time, the parents can further decide whether to initiate an emergency unlocking operation.

[0049] In addition, if Xiaoming attempts to bypass the system restrictions by means such as restarting or restoring the factory settings, the hardware-level timing unit will still continue to record the mobile phone usage time because this timing unit is independent of the operating system and is not affected by the reset operation, ensuring the enforceability and non-bypassability of the usage restrictions.

[0050] This embodiment not only demonstrates the accuracy and real-time nature of the system in monitoring the user's health status but also reflects the effective linkage between the health data and the usage time limit. Through the monitoring of heart rate and blood pressure, the system can issue warnings in a timely manner and enforce restrictions when the user's health condition is abnormal, rather than relying solely on software-level time control. This strategy plays an irreplaceable role in preventing overuse and reducing health risks. Especially among teenagers, it can effectively prevent them from ignoring the potential threats to their own health due to excessive dependence on mobile phones.

[0051] The remote control function of parents provides parents with all-round monitoring and intervention means, ensuring that parents can manage their children's mobile phone usage at any time without directly intervening in the device operation. This not only improves parents' control ability over their children's health management but also makes the management of mobile phone usage between parents and children more transparent and scientific.

[0052] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
