Technical Field

[0001] The present invention relates to the technical field of human body safety feedback monitoring, and in particular to a human body safety feedback monitoring system and method based on a posture sensor. Background Art

[0003] Foreign companies have paid attention to wearable health monitoring systems for a long time. This is mainly reflected in the field of sports and health. Smart bracelets and watches are representatives of this type of products. In 2009, Fitbit launched its first product, Fitbit Tracker. This product is a portable chip clip measuring meter that can record various data of the day and gain a comprehensive understanding of one's own health, including the distance moved, the number of steps moved, the amount of calories consumed, and the time of physical activity.

[0004] In China, the Gudong bracelet launched by Baidu Cloud, the Xiaomi bracelet, and the Geak watch smartwatch launched by Guokr Electronics have good user experience and good market promotion. However, due to the late development of related projects in China, the quality of products on the market varies greatly, and the measurement accuracy of some products needs to be improved.

[0005] In the prior art, the invention patent with application number 201510824163.6 proposes a gait analysis method for skin screening of knee osteoarthritis. Based on the extracted gait feature data of knee joint angle and displacement, neural network modeling and identification are performed on the gait system dynamics of healthy normal people and patients with knee osteoarthritis. However, it is obvious that this method does not realize feedback and record analysis of the data, but only provides a data model for medical treatment, does not play a role in pre-monitoring, does not compare data continuity, model characteristics, etc., and does not realize intelligent wearable technology, which is not conducive to the popularization of the product and its use at any time by healthy people.

[0006] Based on the above research, in order to make up for the shortcomings of previous inventions, this application proposes a technical solution that can overcome the above technical defects. Summary of the invention

[0008] In view of this, the present invention provides a human body safety feedback monitoring system based on a posture sensor to play a role of pre-monitoring.

[0009] The present invention proposes a human body safety feedback monitoring system based on a posture sensor, comprising: a posture sensor, a microcontroller and an information system platform; wherein: the posture sensor is connected to the microcontroller; the microcontroller is connected to the information system platform; the posture sensor comprises a posture sensor module and a power supply module for powering the posture sensor, and the posture sensor is at least arranged at the human arm, hand and knee.

[0010] In a possible design, it also includes memories connected to the microcontroller and the information system platform respectively.

[0011] In a possible design, the attitude sensor includes a base and a protective cover; an annular boss is provided on the front of the base to form a housing cavity for accommodating the attitude sensor module; the protective cover is spherical and is arranged above the annular boss, and is fixed between the protective cover and the base.

[0012] In a possible design, the posture sensor also includes an elastic rubber ring, and the front side of the base is also provided with an annular groove located outside the annular boss, the protective cover and the annular groove are connected by screws, and the elastic rubber ring is located in the annular groove and pressed against the edge of the protective cover.

[0013] In a possible design, the protective cover is also provided with heat dissipation holes.

[0014] In a possible design, the attitude sensor module model is ICM20602; pin 1 of the attitude sensor module is connected to the power supply module; pins 2, 3, 4, and 5 of the attitude sensor module are respectively connected to resistors R1, R2, R3, and R4; pins 9, 10, 11, 12, and 13 of the attitude sensor module are respectively grounded; the power supply module model is MIC5205; pin 1 of the power supply module is connected to a VCC DC power supply; pin 5 of the power supply module is connected to pin 1 of the attitude sensor module.

[0015] In a possible design, the microcontroller and the information system platform are connected via a wireless network.

[0016] In a possible design, the resistance values ​​of the resistors R1 , R2 , R3 , and R4 are all 10K ohms.

[0017] In a possible design, it also includes an alarm connected to the information system platform.

[0018] The present invention also provides a human body safety feedback monitoring method based on a posture sensor, comprising the following steps: when a microcontroller receives a start acquisition command issued by an information system platform, the microcontroller triggers the posture sensor connected thereto to acquire real-time status information of a person to be measured, the posture sensor acquires X-axis acceleration, Y-axis acceleration, Z-axis acceleration, X-axis angular velocity, Y-axis angular velocity, Z-axis angular velocity, X-axis magnetic field intensity, Y-axis magnetic field intensity, Z-axis magnetic field intensity and temperature information of the person to be measured, and sends the acquired information to the microcontroller, the microcontroller calculates the received information to obtain the posture, orientation, three-axis acceleration and temperature information of the person to be measured, and sends the calculated information to the information system platform, the information system platform displays the received information in real time, and when the information system platform issues a stop acquisition command, the posture sensor stops acquiring the real-time status of the person, thereby realizing the monitoring of the posture of the person to be measured in a stationary state or a moving state.

[0019] The present invention has the following beneficial effects: The present invention acquires X-axis acceleration, Y-axis acceleration, Z-axis acceleration, X-axis angular velocity, Y-axis angular velocity, Z-axis angular velocity, X-axis magnetic field intensity, Y-axis magnetic field intensity, Z-axis magnetic field intensity and temperature information of a person to be measured in real time through a posture sensor, and sends the acquired information to a microcontroller connected thereto; the microcontroller calculates the received information to obtain the person's posture, orientation, three-axis acceleration and temperature information, and sends the calculated information to an information system platform connected thereto; the information system platform displays the received information, thereby realizing the monitoring of the person's posture when stationary and the posture when moving.

[0020] The present invention uses Invensense's ICM-20602 chip as the main sensor, which can detect the acceleration and angular velocity of the chip itself at high speed, and send the original collected data to the external processing unit through the slave SPI / IIC bus transceiver inside the chip. The external processing unit performs algorithm processing according to the ICM-20602's own coordinate system, and finally obtains accurate posture data. The power supply module of the present invention uses the MIC5205 low-voltage difference regulator to reduce the input power supply, provide a stable low-voltage power supply for the posture sensor module, and finally improve the detection stability of this sensor module. A posture sensor control circuit with small size, light weight, low power consumption and stable performance is formed by the posture sensor module and the power supply module.

[0021] In the present invention, the design of the elastic rubber ring can not only realize the sealed connection between the annular groove and the protective cover, that is, the seal between the protective cover and the base, but also the screw passes through the protective cover and the elastic rubber ring to be fixed in the annular groove. When the protective cover is impacted or collided with by external force, the elastic rubber ring can cause a small displacement with the base, thereby greatly buffering the external force impact or collision, and playing a good anti-impact and anti-collision role for the electronic components. At the same time, when a small displacement occurs between the protective cover and the base, the volume of the cavity enclosed by the two changes, thereby achieving an effect similar to breathing, thereby accelerating heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the drawings required for use in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present application. For those skilled in the art, other drawings can be obtained based on these drawings without creative work.

[0024] Figure 1 A perspective view of an embodiment of the present invention; Figure 2 A front view of an embodiment of the present invention; Figure 3 for Figure 2 AA section view Figure 4 It is a principle framework diagram of an embodiment of the present invention. DETAILED DESCRIPTION

[0026] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] Description of reference numerals: Base 1, protective cover 2, connecting ear 3, connecting hole 4, filter cloth 5, posture sensor module 6, elastic rubber ring 7, annular groove 8, accommodating cavity 9, annular boss 10, heat dissipation hole 11.

[0028] like Figure 1-4As shown, the present invention proposes a human body safety feedback monitoring system based on a posture sensor, comprising: a posture sensor, a microcontroller and an information system platform; wherein: the posture sensor is connected to the microcontroller; the microcontroller is connected to the information system platform; the posture sensor comprises a posture sensor module and a housing, and the posture sensor is at least arranged at the human arm, hand and knee.

[0029] It also includes memories connected to the microcontroller and the information system platform respectively.

[0030] The housing includes a base 1 and a protective cover 2, and the base 1 and the protective cover 2 are detachable, so as to facilitate installation and removal of the attitude sensor module 6; An annular boss 10 is provided on the front of the base 1 to form an accommodating cavity 9 for accommodating the attitude sensor module 6. The annular boss 10 can protect the attitude sensor module 6 in the accommodating cavity 9. The attitude sensor module 6 is provided with four through holes in the circumference to facilitate fixing the attitude sensor module 6 to the accommodating cavity 9 by screws. The base 1 is disc-shaped and the protective cover 2 is spherical arc-shaped. The design reduces edges and avoids stress concentration. It is suitable for long-term wear by the human body and is not easy to hurt people in the event of a collision. The protective cover 2 is arranged above the annular boss 10 and is fixed between the protective cover 2 and the base 1. The spherical arc-shaped design of the protective cover 2 can avoid stress concentration and can resist stronger external forces or collisions, thereby well protecting the posture sensor module 6 in the accommodating cavity 9.

[0031] Preferably, the protective cover 2 is also provided with heat dissipation holes 11. The heat dissipation holes 11 in the figure are in the shape of strips, which are only for illustration. A better design can be circular and have several heat dissipation holes. In addition, the heat dissipation holes 11 should not be located at the top of the protective cover 2 (which is actually more prone to collision). The heat dissipation holes 11 can be located at the outer edge of the protective cover 2, which can not only play a heat dissipation role, but also have less impact on the overall structural strength of the protective cover 2.

[0032] Furthermore, the present application also includes an elastic rubber ring 7, and an annular groove 8 outside the annular boss 10 is also provided on the front of the base 1. The protective cover 2 and the annular groove 8 are connected by screws. The elastic rubber ring 7 is located in the annular groove 8 and is tightly pressed against the edge of the protective cover 2. The design of the heat dissipation hole 11 can facilitate the heat dissipation of the attitude sensor module 6. At the same time, the design of the elastic rubber ring 7 can not only achieve a sealed connection between the annular groove 8 and the protective cover 2, that is, a seal between the protective cover 2 and the base 1, but also the screws pass through the protective cover 2 and the elastic rubber ring 7 to be fixed in the annular groove 8, and the protective cover 2 is protected. When an external force impacts or collides, the elastic rubber ring 7 can be displaced a small distance from the base 1, thereby greatly buffering the external force impact or collision, and playing a good anti-impact and anti-collision role for the attitude sensor module 6. At the same time, when a small distance displacement occurs between the protective cover 2 and the base 1, the volume of the cavity enclosed by the two changes, thereby achieving an effect similar to breathing, thereby accelerating heat dissipation. It should be noted that when the screw passes through the protective cover 2, the elastic rubber ring 7 and is fixed in the annular groove 8, it may not be completely screwed on, leaving space for the elastic rubber ring 7 to be squeezed and elastically deformed.

[0033] Furthermore, a filter cloth 5 is provided between the protective cover 2 and the annular boss 10. The position of the filter cloth 5 in the figure is for illustration only. In actual application, the filter cloth 5 can be positioned close to the heat dissipation hole 11 to prevent external dust, water vapor, etc. from passing through the heat dissipation hole 11 and contacting the posture sensor module 6, causing interference and unstable operation.

[0034] Preferably, the width of the annular groove 8 is greater than that of the elastic rubber ring 7. Since the elastic rubber ring 7 may be squeezed, expanded, and retracted during use, such a design can prevent the elastic rubber ring 7 from overflowing from the annular groove 8 when being squeezed and expanded.

[0035] Preferably, the protective cover 2 is evenly distributed around the circumference with a plurality of connection holes 4 for screws to pass through, so as to facilitate the detachable connection between the protective cover 2 and the base 1. Furthermore, the connection holes 4 are countersunk holes to prevent the screw heads from protruding too much from the protective cover 2.

[0036] Preferably, the outer edge of the base 1 is further provided with a connecting ear 3, and the setting of the connecting ear 3 is convenient for fixing the posture sensor by means of a strap or the like, so as to facilitate wearing or carrying.

[0037] Preferably, the protective cover 2 and the base 1 are both made of ABS engineering plastics, which are not only lightweight but also have high structural strength and are harmless to the human body. They can not only well protect the posture sensor module 6 but also are suitable for long-term wearing.

[0038] Among them, the model of the attitude sensor module is ICM20602; pin 1 of the attitude sensor module is connected to the power supply module; pins 2, 3, 4, and 5 of the attitude sensor module are respectively connected to resistors R1, R2, R3, and R4; pins 9, 10, 11, 12, and 13 of the attitude sensor module are respectively grounded; the model of the power supply module is MIC5205; pin 1 of the power supply module is connected to a VCC DC power supply; pin 5 of the power supply module is connected to pin 1 of the attitude sensor module.

[0039] Wherein, the microcontroller and the information system platform are connected via a wireless network.

[0040] Wherein, the resistance values ​​of the resistors R1, R2, R3, and R4 are all 10K ohms.

[0041] Among them, it also includes an alarm connected to the information system platform.

[0042] The present invention provides a human body safety feedback monitoring method based on a posture sensor. The method is based on the above-mentioned human body safety feedback monitoring system based on a posture sensor and comprises the following steps: when a microcontroller receives a start acquisition command issued by an information system platform, the microcontroller triggers the posture sensor connected thereto to acquire real-time status information of a person to be measured, the posture sensor acquires X-axis acceleration, Y-axis acceleration, Z-axis acceleration, X-axis angular velocity, Y-axis angular velocity, Z-axis angular velocity, X-axis magnetic field intensity, Y-axis magnetic field intensity, Z-axis magnetic field intensity and temperature information of the person to be measured, and sends the acquired information to the microcontroller; after the microcontroller calculates the received information, the posture, orientation, three-axis acceleration and temperature information of the person to be measured are obtained, and the calculated information is sent to the information system platform; the information system platform displays the received information in real time; when the information system platform issues a stop acquisition command, the posture sensor stops acquiring the real-time status of the person, thereby realizing the monitoring of the posture of the person to be measured in a stationary state or a moving state.

[0043] In addition to ICM-20602, each component also has a wireless communication chip. These chips can form a self-network, and then the router chip is responsible for uploading the data collected by all components to the information system platform in real time. The information platform processes, analyzes and predicts the body's condition in real time through big data.

[0044] Based on the data of someone's healthy life, the data of healthy life means that one should do what he should do at what time every day, and the completion time of each task is basically regular.

[0045] However, if a person is sitting and not moving for a certain period of time, as measured by his leg, waist, and hand sensors, then he is sedentary for a long time.

[0046] According to the sensors on his legs, waist and hands, it was detected that he was sitting down and was not moving, which was the sitting down alarm.

[0047] According to the sensors on his legs, waist and hands, it was detected that he was lying down at times when he shouldn't have been, which was the lying down alarm.

[0048] Specifically, the electronic components of the attitude sensor of the present application are the same as those of the Chinese utility model patent CN217238120U. The attitude sensor includes an attitude sensor module, a power supply module for powering the attitude sensor module, and an external processing unit for processing the collected attitude data.

[0049] In this embodiment, the attitude sensor module is Invensense's ICM-20602 high-performance six-axis MEMS motion attitude sensor, which detects the acceleration and angular velocity of the chip itself, and sends the acquired acceleration and angular velocity of the chip to the external processing unit through the slave SPI / IIC bus transceiver inside the chip. The external processing unit can perform algorithm processing according to the ICM-20602's own coordinate system. The first pin of the attitude sensor is connected to the fifth pin of the power supply module.

[0050] The 2nd, 3rd, 4th and 4th pins of the attitude sensor are connected to resistors R1, R2, R3 and R4 respectively; the four resistors R1, R2, R3 and R4 are connected in parallel to the power supply module. The 9th, 10th, 11th, 12th and 13th pins of the attitude sensor are grounded. The 16th pin of the attitude sensor is connected to the power supply module.

[0051] In this embodiment, the model of the power supply module is MIC5205, the first pin and the third pin of the power supply module are both connected to a VCC direct current power supply; the second pin of the power supply module is grounded.

[0052] In this embodiment, the power supply module is connected to a power supply indication circuit for indicating normal power supply. When the 5th pin of the power supply module normally outputs voltage to the posture sensor module, the power supply indication circuit can be turned on, so that the indicator light of the power supply indication circuit lights up.

[0053] In this embodiment, the attitude sensor module is further connected to a resistor.

[0054] In this embodiment, the resistance values ​​of the resistors R1 , R2 , R3 , and R4 are all 10K ohms.
