Description

[Technical Field]

[0001] The present invention relates to a handheld cane system with smart measurements, and more particularly to a handheld cane system with smart measurements that can measure body conditions. [Background technology]

[0002] With the advancement of modern hygiene and medical science, the average lifespan of modern people has increased significantly, and as a result, people generally have to face the problem of aging. Due to muscle loss and a decline in hematopoietic function, falls in the elderly can be extremely fatal. To prevent damage to vital organs and the formation of blood clots, more observation is required after a fall, and the damage may be delayed, with deterioration possibly occurring weeks or months later. If the user's physical condition can be detected early, falls can be prevented early, significantly reducing the user's long-term pain and risk, and significantly reducing the psychological stress of family members, care costs and valuable time, health insurance, and medical costs.

[0003] According to statistics from the Ministry of the Interior, the proportion of people aged 65 or older exceeds 14% of Taiwan's total population, making it truly an aging society. With growing health awareness, more and more people are wearing health watches to monitor their physical condition in real time. While these smart devices can share data with family members, health watches are primarily non-interactive body monitoring devices, making it difficult for seniors to accurately monitor their current usage. Furthermore, underwear that can interactively monitor the user's physical condition is crucial for seniors. Canes are important walking aids, so researchers are researching and developing canes that can interactively monitor and monitor the user's physical condition, allowing users to know their current condition early and take early preventative measures to avoid injury.

[0004] Therefore, the present inventors have taken this into consideration and conceived the concept of the invention, designed it based on their many years of experience, and completed the present invention after much discussion, prototype testing of samples, and several modifications and improvements. Summary of the Invention

[0005] Technical issues to be solved The present invention provides a handheld cane system with smart measurement, which has the function of smart detection and can infer the user's gait and physical data, track the user's gait and physical condition in real time, and achieve the effect of preventive measures.

[0006] Technical points to solve the problem The present invention provides a system for a handheld cane with smart measurement, which includes a smart handheld cane, a smart device, and smart software. The smart handheld cane has a handheld cane body, and a handheld cane handle is provided at the top of the handheld cane body for a user to hold and support. The handheld cane body further includes a 9-axis inertial sensor, a pushing force sensor, and a photoelectric sensor. The 9-axis inertial sensor is provided with a 3-axis accelerometer, a 3-axis gyroscope, and a 3-axis magnetometer, and the 3-axis accelerometer is used to measure the X, Y, and Z axes of the smart handheld cane. The three-axis gyroscope is used to measure the rotation speed of the smart handheld cane on the three axes of X, Y, and Z, and calculate the angle to determine whether the frequency of movement is stable when the smart handheld cane is used. The three-axis magnetometer performs error correction and direction determination on the six-axis data of the three-axis accelerometer and the three-axis gyroscope, and can determine the speed of movement, the number of steps, and whether the user's hand is shaking when the smart handheld cane is being used. The smart cane can measure whether the direction of movement is stable and straight when used; the pushing force sensor is used to detect the pushing force applied by the user's hand, and can measure the magnitude of the pushing force when the smart cane is used; the photoelectric sensor is used to optically detect changes in the user's heart rate; when the 9-axis inertial sensor, pushing force sensor, and photoelectric sensor do not detect the values, a warning light and a buzzer will issue a light and sound warning, respectively; the smart cane transmits the values ​​detected by the 9-axis inertial sensor, pushing force sensor, and photoelectric sensor to the smart device via Bluetooth; the smart device is a smartphone, and can detect the user's moving distance and number of steps; the smart device is equipped with a GPS, a communication unit, and a warning unit; the smart device can detect the current location using the GPS; the smart software is installed in the smart device and displayed; and the smart device and smart software are used toThe data is notified and transmitted to at least one contact person, and the smart software can display the numerical data sensed and compiled by the 9-axis inertial sensor, the pushing force sensor, the photoelectric sensor and the smart device, and further inductively obtain the user's normal walking style and physical condition numerical value, and the contact person can also check the numerical data through the smart software. When the user's walking style and physical condition numerical value are abnormal, the smart device can transmit the current location to the contact person through the GPS, and the smart device can call the contact person through the communication unit, and the smart device can sound a buzzer or send a short message to the contact person through the alarm unit.

[0007] The main object of the present invention is to enable users to rely on the assistance of the smart handheld cane to reduce the discomfort of walking. The three-axis accelerometer can determine the user's walking speed and steps and whether there is hand tremor. The three-axis gyroscope can determine whether the user is swinging the smart handheld cane stably and whether the frequency of movement is stable. The three-axis magnetometer can perform error correction and direction determination on the six-axis data of the three-axis accelerometer and the three-axis gyroscope to determine whether the user's movement direction is stable and straight, and can confirm whether the user's legs are strong or their sense of balance is normal. The pushing force sensor can detect the pushing force applied by the user to determine whether the user's leg strength has decreased and they need to use their hands to help them walk with the smart handheld cane. The photoelectric sensor can detect the heart rate, thereby knowing the user's physical condition most directly. The GPS can record the walking location and track the user to prevent them from getting lost. The 9-axis inertial sensor can use the 9-axis data from the 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer, as well as the data measured by the pressure sensor, photoelectric sensor, and smart device, to determine the user's walking style and physical condition, which can be displayed to the user or the contact person by the smart software for care.

[0010] In order to better understand and appreciate the objects, features, and advantages of the present invention, the following detailed description will be made with reference to the drawings in which: BRIEF DESCRIPTION OF THE DRAWINGS

[0011] First, as shown in Figures 1 to 3, the present invention provides a system for a handheld cane with smart measurement, which includes a smart handheld cane (10), a smart device (20), and smart software (30). The smart handheld cane (10) has a handheld cane body (11), and a handheld cane handle (111) is provided at the top of the handheld cane body (11) for a user to hold and support. The handheld cane body (11) further includes a 9-axis inertial sensor (12), a pushing force sensor (13), and a photoelectric sensor (14). The inertial sensor (12) is provided with a three-axis accelerometer (121), a three-axis gyroscope (122), and a three-axis magnetometer (123). The three-axis accelerometer (121) is used to measure the gravitational acceleration of the smart handheld cane (10) on three axes, X, Y, and Z, to measure the moving speed, number of steps, and whether the user's hand is shaking when the smart handheld cane (10) is being used. The three-axis gyroscope (122) is used to measure the rotation speed of the smart handheld cane (10) on three axes, X, Y, and Z, to calculate the angle. The three-axis magnetometer (123) performs error correction and direction determination on the six-axis data of the three-axis accelerometer (121) and the three-axis gyroscope (122), and can measure whether the movement direction of the smart handheld cane (10) is stable and moving in a straight line when it is used. The pushing force sensor (13) is used to detect the pushing force applied by the user's hand, and can measure whether the movement frequency of the smart handheld cane (10) is stable when it is used. The photoelectric sensor (14) is used to optically detect changes in the user's heart rate, and when the 9-axis inertial sensor (12), the pushing force sensor (13) and the photoelectric sensor (14) do not detect a value, the warning lamp (15) and the buzzer (16) emit light and sound, respectively, to warn the user. The smart handheld cane (10) transmits the values ​​detected by the 9-axis inertial sensor (12), the pushing force sensor (13) and the photoelectric sensor (14) to the smart device (20) via Bluetooth.

[0012] As shown in Figures 3 to 8, the smart device (20) is a smartphone, capable of measuring the user's travel distance and number of steps, and is equipped with a GPS (21), a communication unit (22), and an alert unit (23). The smart device (20) can measure its current location using the GPS (21). The smart device (20) has installed and displayed smart software (30). The smart device (20) and smart software (30) can be used to notify and transmit data to at least one contact person (40). The smart software (30) also includes the 9-axis inertial sensor (12), the pressure sensor (13), the optical The electrical sensor (14) can display the collected numerical data from the smart device (20), and then inductively obtain the user's normal walking pattern and physical condition values. The contact person (40) can also check the numerical data through the smart software (30). When the user's walking pattern and physical condition values ​​are abnormal, the smart device (20) can send the current location to the contact person (40) through the GPS (21), call the contact person (40) through the communication unit (22), and sound a buzzer or send a short message to the contact person (40) through the warning unit (23).

[0013] According to the above structure, the user can rely on the assistance of the smart handheld cane (10) when walking to reduce the discomfort of walking. The three-axis accelerometer (121) can detect the user's walking speed and number of steps and whether there is any hand tremor. The three-axis gyroscope (122) can detect whether the user is swinging the smart handheld cane (10) stably, and whether the frequency of movement is stable. The three-axis magnetometer (123) can perform error correction and direction determination on the six-axis data of the three-axis accelerometer (121) and the three-axis gyroscope (122) to determine whether the user's movement direction is stable and straight, and can confirm whether the user's legs are strong or their sense of balance is normal. The pushing force sensor (13) can measure the pushing force applied by the user to know whether the user's leg strength has decreased and they need to use their hands to help them walk with the smart handheld cane (10). The photoelectric sensor The sensor (14) can detect the heart rate, thereby directly knowing the user's physical condition. The GPS (21) can record the walking location and track the user to prevent them from getting lost. The 9-axis inertial sensor (12) uses the 9-axis data from the 3-axis accelerometer (121), 3-axis gyroscope (122), and 3-axis magnetometer (123), as well as the data measured by the push force sensor (13), photoelectric sensor (14), and smart device (20) to determine the user's walking style and physical condition, which can be displayed by the smart software (30) to the user or the contact person (40) for care. The smart software (30) can also compile long-term numerical data. If the user notices any abnormalities in their walking style or physical condition while using the smart cane (10), the smart device (20) and smart software (30) will notify the contact person (40) and send an alarm immediately, thereby ensuring the health and safety of the user.

[0014] In actual use, as shown in FIG. 5, the smart software (30) can display the numerical data measured and compiled by the 9-axis inertial sensor (12); as shown in FIG. 6, the smart software (30) can display the numerical data measured and compiled by the pushing force sensor (13); as shown in FIG. 7, the smart software (30) can display the numerical data measured and compiled by the pushing force sensor (13), the photoelectric sensor (14), and the smart device (20); as shown in FIG. 8, the smart software (30) can display the numerical data measured and compiled by the GPS (21). The design and configuration of the smart software (30) makes it more convenient for the user and the contact person (40) to view the measured and compiled data through the smart software (30), thereby achieving tracking of the user's walking style and physical condition.

[0015] As shown in Figure 1, the present invention provides a handheld cane system with smart measurement, in which at least one battery (17) is provided in the handheld cane body (11), and the battery (17) is replaceable or can be charged through a charging port (18).

[0016] As shown in Figure 1, the present invention provides a smart measurement handheld cane system, in which the battery (17) supplies power to the lighting lamp (19) to give the smart handheld cane (10) lighting function, improving safety in poor lighting conditions.

[0017] As shown in FIG. 1, the present invention provides a handheld cane system with smart measurement, in which the pushing force sensor (13) and photoelectric sensor (14) are installed in the handle (111) of the handheld cane, the pushing force sensor (13) is used to measure the force with which the user pushes the handle (111) of the handheld cane, and the photoelectric sensor (14) can photoelectrically sense the blood vessels in the user's hand to know the changes in heart rate.

[0018] The present invention provides a smart measurement system for a walking stick, in which when the three-axis accelerometer (121) detects that the speed of movement exceeds 50% of the normal speed, the three-axis gyroscope (122) detects that the smart walking stick (10) is at an angle of more than ±45 degrees relative to the ground, the three-axis magnetometer (123) detects that the smart walking stick (10) has no direction of movement, the pushing force sensor (13) continues to be unable to measure the pushing force, and the photoelectric sensor (14) continues to be unable to measure the heart rate, and the nine-axis inertial sensor (12), the pushing force sensor (13) and the photoelectric sensor (14) are unable to detect any values ​​for more than 30 seconds, it is determined that the user is in danger of falling. After 15 seconds, the warning lamp (15) will emit a light warning, after 30 seconds, the buzzer (16) will emit a buzzer sound warning, after 60 seconds, the warning unit (23) of the smart device (20) will send three consecutive short messages to the contact person (40), after 120 seconds, the communication unit (22) of the smart device (20) will call the contact person (40) to notify them, after 180 seconds, the communication unit (22) of the smart device (20) will call 119 to request help, and the user can confirm that the smart handheld cane is not in use and press the stop key (not shown) to stop the warning.

[0019] The present invention provides a smart measurement system for a handheld walking stick, wherein the three-axis accelerometer (121) measures the user's moving speed, and combines it with the number of steps measured by the smart device (20) and the distance traveled measured by the GPS (21). The three numerical data are inductively calculated by the smart software (30). The average usage time and number of steps per 100 meters for the first three days after the user starts using the smart walking stick (10), and the data measured by the three-axis accelerometer (121), smart device (20) and GPS (21) have a fluctuation rate of within 10%. If the rate of change is maintained, it is deemed to be a reasonable change in normal movement, and if it exceeds this rate, it is deemed to be an abnormal state. For example, if a user takes an average of 90 seconds to walk 250 steps per 100 meters, and the subsequent usage time is between 81 and 99 seconds and the number of steps is between 225 and 275, this is a normal and reasonable change. However, if the rate of change exceeds 10%, for example, the usage time is between 99 and 108 seconds and the number of steps is between 275 and 300, it is deemed that the user's movement is slowing down, and the user and the contact person (40) should be notified and should consult a doctor as soon as possible to check their health.

[0020] The present invention provides a smart measurement system for a handheld cane, wherein the three-axis accelerometer (121) measures the frequency with which the user shakes the smart handheld cane (10) to measure the state of the user's hand shaking, the three-axis accelerometer (121) measures the acceleration values ​​of the three axes, and the smart software (30) performs inductive calculations. If the data measured by the three-axis accelerometer (121) maintains a fluctuation rate within 10%, it is determined to be a reasonable variation of normal movement, and if it exceeds this, it is determined to be an abnormal state. For example, if the user's original average value of the X axis is 10km / h, the average value of the Y axis is 5km / h, and the average value of the Z axis is 15km / h, and the fluctuation rate is within 10%, it is determined to be an abnormal state. If the rate of change exceeds 10% and the average values ​​of the three axes decrease, for example, the average value of the X axis is 8km / h, the average value of the Y axis is 4km / h, and the average value of the Z axis is 12km / h, it means that the rehabilitation or treatment is effective and the user's hand tremors have decreased. However, if the rate of change exceeds 10% and the average values ​​of the three axes increase, for example, the average value of the X axis is 12km / h, the average value of the Y axis is 6km / h, and the average value of the Z axis is 18km / h, it means that the user's hand tremors have worsened, or the user's hands have started to tremble even though they were not trembling before. The user and the contact person (40) should be notified and should consult a doctor as soon as possible to check their health.

[0021] The present invention provides a smart measurement system for a walking stick, wherein the three-axis gyroscope (122) measures the frequency of the user's foot movement, and the three-axis angle value changes when the user moves the smart walking stick (10) through the three-axis gyroscope (122), and the smart software (30) performs inductive calculation. For the first three days after the user starts using the smart walking stick (10), if the data measured by the three-axis gyroscope (122) maintains a fluctuation rate within 10%, it is determined to be a reasonable fluctuation amount of normal movement, and if it exceeds this, it is determined to be an abnormal state. For example, the average value of the X axis is The average value of the Y axis is between 0 and 5 degrees, the average value of the Y axis is between +15 and -15 degrees, and the average value of the Z axis is between +5 and 0 degrees. If the rate of change thereafter is within 10%, it is considered a normal change, and the frequency of the user's walking movement is stable. However, if this is not the case, for example, if the change exceeds 10%, the frequency of the user's walking movement is determined to be abnormal and unstable. After the user and the contact person in question (40) are informed of this, they should investigate the reason for the increase or decrease in the value, consult a doctor as soon as possible, and check their physical condition. They should also pay attention to whether the user is exercising or increasing the amount of exercise.

[0022] The present invention provides a smart measurement system for a walking stick, in which the three-axis magnetometer (123) measures the direction of travel of the user using the smart walking stick (10), and combines it with the position data measured by the GPS (21). The two numerical data are inductively calculated and compared by the smart software (30). If the user's direction of travel using the smart walking stick (10) maintains a fluctuation rate of within 20%, it is determined to be a reasonable variation of normal movement, and if it exceeds this, it is determined to be an abnormal state. For example, when walking normally, if the direction is not north +10 degrees, If the angle is -10 degrees and the subsequent direction is +8 degrees or -8 degrees north, or +12 degrees or -12 degrees north, it is within the normal fluctuation rate and is therefore normal. However, if the subsequent direction is +15 degrees or -15 degrees north, the rate of change between the direction of the smart handheld cane (10) and the direction of movement of the GPS (21) is too large, so it is determined to be an abnormal walking style, indicating that the user is frequently deviating left and right while moving and is unable to move in a straight line. After the user and the contact person (40) are informed of this, they will be advised to consult a doctor as soon as possible to check their health.

[0023] The present invention provides a smart measuring handheld cane system, wherein the pushing force sensor (13) measures the pushing force when the user uses the smart handheld cane (10), and the numerical data is recursively calculated by the smart software (30), and when the user uses the smart handheld cane (10), if the pushing force changes by more than 25% for more than 10 minutes, it will be deemed abnormal.

[0024] As shown in FIG. 3, the present invention provides a handheld cane system with smart measurement, wherein a plurality of said contact persons (40) can be organized into at least one contact group (50), and said smart device (20), smart software (30) can be used to notify and transfer data to said contact group (50).

[0025] The detailed principles of the handheld cane with smart measurement system of the present invention can be seen from:

[0026] The three-axis accelerometer (121) is commonly known as a G-sensor, and is used to detect the physical gravitational acceleration (unit: m / s^2) on the X, Y, and Z axes. The inertial force of the three axes is determined by the numerical distribution of the gravitational acceleration on the X, Y, and Z axes.

[0027] The three-axis gyroscope (122) is usually called a Gyro-sensor and is used to measure the rotation speed (unit: rad / s) on the X, Y, and Z axes. In the present invention, the three-axis gyroscope (122) is used to measure the amplitude and frequency of the smart handheld cane (10). If the amplitude of the smart handheld cane (10) is too small or too large, attention should be paid to whether there is any abnormality in the frequency and stride length of each step when the user walks.

[0028] The three-axis magnetometer (123) is also called a geomagnetic sensor or a magnetic sensor, and can be used to measure the magnetic field strength and direction, and can also be used to determine the orientation of the equipment. The principle of the three-axis magnetometer (123) is similar to that of a compass. When used, it performs error correction and direction determination on the six-axis data of the three-axis accelerometer (121) and the three-axis gyroscope (122). The value of the three-axis accelerometer (121) can determine the state in which the smart handheld cane (10) is placed, but it cannot know the upside-down or rotation speed of the smart handheld cane (10), and it cannot sense the instantaneous state of the smart handheld cane (10). Since it is not possible to know the actual direction, the three-axis gyroscope (122) is added, and through the integration of the three-axis accelerometer (121) and the three-axis gyroscope (122), the movement state of the smart handheld cane (10) can be obtained. The integration calculation has a slight difference from the actual state, and the impact is small in a short time, but the error continues to accumulate, and after a long period of use, an obvious deviation will occur. Even if the six-axis device rotates 360 degrees, the image will not return to the origin, just like when a person gets lost and cannot find the direction of north. At such times, it is necessary to know the correct direction, so the three-axis magnetometer (123) is added to make corrections and find the correct direction.

[0029] The 9-axis inertial sensor (12) uses the 3-axis accelerometer (121), 3-axis gyroscope (122), and 3-axis magnetometer (123) to obtain 9-axis values ​​through a fusion algorithm, which can then calculate the correct posture of the object. Currently, 9-axis fusion algorithms include Kalman filtering, particle filtering, and complementary filtering algorithms. For developers, all fusion algorithms basically input the values ​​and timestamps from the 9-axis sensors, obtain the values ​​output by the fusion algorithm, and then comprehensively determine the user's status.

[0030] The pushing force sensor (13) is a load cell or weighing sensor, which is a special type of force sensor consisting of a strain gauge and a bridge circuit. When a pushing or pulling force is applied, it generates a voltage output proportional to the force. Load cells include compression, pulling / compression, double shear beam, cantilever beam, single-point force measurement, and annular load cells. They are used in weighing devices and are calibrated in kilograms (kg). The load cell elastically deforms in response to the gravitational load, and the strain gauge installed inside converts the deformation into a proportional voltage signal. This achieves a high accuracy of ±0.01% to ±0.05%, so the pushing force sensor (13) can accurately record the pushing force applied by the user when using the smart handheld cane (10).

[0031] When the heart beats, it pumps blood into the arteries, increasing blood flow and reducing the amount of reflected light. Between two consecutive heartbeats, the blood flow at the wrist weakens and the amount of reflected light increases. The photoelectric sensor (14) optically measures the time between high and low light intensities to determine the interval between heartbeats and then calculates the heart rate based on these values. Optical heart rate is measured using photoplethysmography (PPG) technology to measure changes in subcutaneous blood volume. In theory, PPG signals can be measured from any part of the body (e.g., finger, earlobe, temple, wrist, etc.). Compared to traditional methods of measuring heart rate by analyzing the electrical activity of the heart, this method is less accurate but more convenient and smooth, and is suitable for real-time tracking of physical status.

[0032] The smart device (20) is a smartphone, and current smartphones have related sensors such as an accelerometer that can measure acceleration mounted on the circuit board. When the smartphone is moved on any plane or in space, the direction and speed of the movement are measured, and the distance of the movement, the number of steps taken by the user, and other numerical values ​​can be obtained through further calculations. Whether the smartphone is in a pocket or attached to the arm during exercise, the smartphone can accurately calculate the basic movement values ​​of the user, and the smart device (20) can measure the user's distance traveled and the number of steps taken.

[0033] The smart software (30) may be an application installed on the smart device (20). When the smart cane (10) is used, the 9-axis inertial sensor (12), the pushing force sensor (13), the photoelectric sensor (14) and the smart device (20) measure the user's distance traveled and the number of steps taken, and the location value measured by the GPS (21) can be displayed on the smart software (30). Depending on different parameters such as the user's age, the criteria for abnormal walking patterns and physical conditions vary. The smart software (30) can also compile and organize long-term numerical data to assist in determining abnormal conditions.

[0034] The above is merely one embodiment of the present invention and is not intended to limit the scope of the present invention, and all changes and modifications made within the scope of the claims of the present invention are also within the scope of the present invention.
