Several embodiments of the portable motion monitoring system of the present invention are described below in accordance with the drawings. 1 is a system diagram of a portable motion monitoring system of the present invention. As shown, the portable motion monitoring system of the present invention mainly includes a motion sensing device 10 and a mobile terminal device 20. Although the mobile terminal device 20 can be an independent electronic device dedicated to motion monitoring, in a preferred embodiment of the present invention, the motion monitoring system is built in the form of application software in a smart mobile terminal device 20. . The smart mobile terminal device 20 can be an electronic device such as a smart phone or a tablet computer. After the smart mobile terminal device 20 executes the application software after the completion of the establishment, the communication, calculation and storage capability of the smart mobile terminal device 20 can be used, and the sensing signal of the motion sensing device 10 can be received and calculated. The motion type and the motion state represented by the sensing result data generated by the motion sensing device 10 are interpreted, and the determination result is generated and the determination result is executed according to a predetermined determination rule. Regardless of the form, the mobile terminal device 20 is equipped with communication capability to obtain sensing result data from the motion sensing device 10, and has computing power to make a judgment based on the sensing result data, and display capability. To display information related to the judgment result.

According to the present invention, the motion sensing device 10 has at least one inertial sensor 11 for sensing the displacement of the inertial sensor 11 itself and outputting a displacement sensing signal. The inertial sensor 11 is typically a sensor structure fabricated in microelectromechanical technology and has an output electrode for outputting a displacement sensing signal. The motion sensing device 10 also includes a processing circuit 12 for receiving the output signal of the inertial sensor 11 and converting it into a sensing signal that can be transmitted and processed. If the motion sensing device 10 contains more than one inertial sensor, it is possible to equip the individual inertial sensors with a processing circuit. Each of the inertial sensors is connected to the wireless transmitter 13 by a signal line through a corresponding processing circuit.

The inertial sensor 11 can be any commercially available displacement sensing structure for sensing the motion of the sensor itself, such as the presence or absence of motion, the direction of motion, the speed of motion, etc., to produce an electrical signal. Suitable inertial sensors 11 can be, for example, commercially available accelerometer structures, angular velocity meter structures, magnetometer structures, or combinations thereof in any manner. The inertial sensor 11 typically needs to provide displacement sensing capabilities in at least two directions, such as two axial displacement sensing capabilities. However, more than two axes, such as three axes, six axes, nine axes, etc., are suitable for use in the present invention. The so-called two axes may be two orthogonal axial directions in space, or an angular direction and a linear axial direction at an angle to the plane of the angle. If it is a three-axis displacement sensing structure, it may be a three-axis accelerometer or a three-axis angular velocity meter structure; if it is a six-axis displacement sensing structure, it may be a three-axis accelerometer combined with a three-axis angular velocity meter. Structure, or a three-axis accelerometer combined with a three-axis magnetometer; if it is a nine-axis displacement sensing structure, it may be a three-axis accelerometer, a three-axis angular velocity meter combined with a three-axis magnetometer structure.

Inertial sensors with the above features and capabilities are well established technologies and a variety of products are commercially available. Combinations or combinations of different displacement sensing structures are also well known to those skilled in the industry. For example, U.S. Patent Publication No. 2016/084871 A1 discloses an inertial sensor structure that combines the functions of an accelerometer and a magnetometer. The relevant technical details are not mentioned here.

The processing circuit 12 is connected to the inertial sensor 11, that is, an electrode (not shown) of the inertial sensor 11 to receive the sensing signal output by the inertial sensor 11. The function of the processing circuit 12 is mainly to sample the signal output by the inertial sensor 11 and convert it into a predetermined form and output it to the outside world. Usually, the processing circuit 12 picks up the signal output by the inertial sensor 11 according to a predetermined or set sampling frequency, and converts it into signals of different levels by using a simple analog-to-digital converter (not shown), for example, different bits. Quasi-voltage signal. Such processing circuitry can also be implemented using any commercially available processing circuitry and is a known technique. The details are not to be repeated here.

A displacement sensing element having a sensing capability of two or more axes, that is, a device including at least one displacement sensing structure and one processing circuit, and capable of outputting a sensing result signal in a digital form, and also has many commercially available products. This industry expert can utilize such commercially available products or techniques to achieve the inertial sensor 11 and processing circuitry 12 required by the present invention.

After the athlete starts to exercise, the inertial sensor 11 continuously senses its own displacement and continuously outputs the sensing signal. FIG. 2 is a waveform diagram showing the sensing result data outputted by an embodiment of the inertial sensor 11 of the present invention. As shown, the inertial sensor 11 is a three-axis accelerometer that is worn on the upper of the athlete and senses the displacement of the inertial sensor 11 when the athlete is running, and outputs a sensing signal. After the signal is processed, it becomes the waveform shown in FIG. 2. The data represented by such a waveform can be accepted by a variety of animation generating devices as a basis for generating motion recording animations.

The motion sensing device 10 further has a wireless transmitter 13 for outputting the sensed result processed by the processing circuit 12 to the outside. Any commercially available wireless transmitter can be adapted for use in the present invention. The wireless transmitter 13 can also use a wireless transceiver to establish a communication channel with the mobile terminal device 20 to exchange data with each other. However, in most applications of the present invention, the motion sensing device 10 only needs to be able to provide sensing result data. The wireless transmitter 13 is sufficient to provide the necessary functionality. Generally, the wireless transmitter 13 continuously sends the sensing result signal in accordance with the sampling frequency of the processing circuit 12. It is also possible to provide a sensing result signal with a different set output rate. The wireless transmitter 13 having such a function is usually a simple commercially available wireless transmitter that sends a sensing result signal via a predetermined wireless communication channel. The wireless communication channel can be a short-range wireless communication channel, such as a Bluetooth channel. The relevant technical details are mature technologies and need not be described here.

The sensing result signal output by the motion sensing device 10 may additionally include code information of the sensing device 10 for recognition by the mobile terminal device 20. In particular, when the portable motion monitoring system is used to serve the majority of the motion sensing device 10, the sensor code data is added to the sensing result signal to prevent the determination error.

The motion sensing device 10 also includes a power supply unit 14 for providing the power required by the inertial sensor 11, the processing circuit 12, and the wireless transmitter 13. The power supply unit 14 will typically include a battery, a charging circuit and a power saving circuit (neither shown) to provide off-line sensing for a comparable amount of time. The power supply unit 14 can of course also use any commercially available power supply unit. The motion sensing device 10 can further include a switch or select button 15 for turning the processing circuit 12 and the wireless transmitter 13 on and off. If the button 15 is not provided, a wake-up circuit (not shown) can be used to turn on the processing circuit 12 and the wireless transmitter 13 when a specific displacement mode is detected, and no displacement is detected for a certain period of time. When the signal is detected, the operation of the processing circuit 12 and the wireless transmitter 13 is stopped.

The button 15 can also be used to select the operating mode of the motion sensing device 10. For example, a setting circuit (not shown) can be used to set several operating modes, such as a running mode, a walking mode, a bicycle mode, and the like. Individual sampling frequencies, pickup detection signal types, etc. are individually assigned, and detection signals conforming to specific modalities are output. In addition to the setting of the button 15, the working mode can be set by an external device such as the mobile terminal device 20. At this time, the wireless transmitter 13 should be a wireless transceiver to receive the settings of the mobile terminal device 20. In this application example, the information output device 23 of the mobile terminal device 20 should be equipped with a touch display device, or other input device for the user to select the working mode of the motion sensing device 10, and sense the motion. The device 10 performs setting.

However, since in most embodiments of the present invention, the mobile terminal device 20 has been equipped with a working mode determination capability or a motion mode determination capability, the motion sensing device 10 is generally not required to be equipped with a working mode selection function.

Both the power supply unit 14 and the push button/switch 15 can be realized by using a commercially available product. In addition, the motion sensing device 10 having the above-described components, architecture, and functions can also be implemented using commercially available wireless displacement sensing components.

The motion recording device 100 of the present invention is particularly suitable for recording motions that are more periodic, such as running, walking, cycling, and the like. Thus, the motion sensing device 10 is provided with a wearing device 16 for fitting the motion recording device to an athlete, in particular on a foot or on a shoe. Thus, in the example of FIG. 1, the wearing device 16 for equipping the motion sensing device 10 on the limb 19 includes leggings for attaching the motion sensing device 10 to the athlete's ankle. However, it is known in the art that the motion sensing device 10 can be worn on other limbs or body parts, or can be worn on shoes to obtain the same or similar motion recording effect. The wearing device 16 can also be in other forms, such as adhesive tape, buckles, clips, chains, suction cups, magnetic chucks, and the like. As long as it can be attached to the animal body and move as the object moves.

Fig. 3 is a block diagram showing a power applied to the mobile terminal device of the present invention. As shown, the mobile terminal device 20 includes an arithmetic device 21, a wireless communication device 22 coupled to the computing device 21, an information output device 23 coupled to the computing device 21, and a coupled to the computing device. Device 21 and/or memory device 24 of the wireless communication device 22.

The wireless communication device 22 is for receiving an output signal of the motion sensing device for processing by the computing device 21. The wireless communication device 22 provides a communication interface for receiving the sensing result data sent by the motion sensing device 10. In a typical application, the wireless transmitter 13 of the motion sensing device 10 continuously sends out sensing result data after startup. The wireless communication device 22 can receive the sensing result data from the motion sensing device 10 after a certain negotiation procedure using a commercially available short-range wireless communication chip, such as a Bluetooth chip. This communication negotiation process between wireless communication devices is already a mature technology, and experts in this industry are easy to achieve the necessary design to implement the establishment of communication channels. Although the data transmission between the two also passes through the wired transmission channel, as the application of the motion monitoring system, it is still suitable for wireless transmission. It may be necessary for the user to pair the two devices when using the wireless communication channel.

The computing device 21 can be any microprocessor equipped with the necessary software programs for processing the sensing result data received by the wireless communication device 22. The computing device 21 is coupled to the wireless communication device 22 to receive the sensing result data received by the wireless communication device 22. The memory device 24 can be any data storage device suitable for use in an electronic device, such as a memory chip or the like. The memory device 24 is coupled to the computing device 21 for storing a software program required by the computing device 21, that is, a motion monitoring program, and processing result information of the computing device 21. The memory device 24 can also be coupled to the wireless communication device 22 for storing the sensing result data received by the wireless communication device 22. In addition, the information output device 23 is coupled to the computing device 21 for outputting processing result information of the computing device 21. The information output device 23 is typically a sound output device and/or a video output device. As the sound output device, for example, an earphone can be provided to expand the output sound and to facilitate the wearer's wearing. The information output device 23, if it is an image output device, can be a small display screen, such as a display screen built on the glasses, and the processing of the computing device 21 is displayed in text and/or graphics during the movement of the player. result. The mobile terminal device 20 can also be equipped with a necessary power supply (not shown) to facilitate long-term operation of the mobile terminal device 20.

The arithmetic device 21, the wireless communication device 22, the information output device 23, the memory device 24, the power supply, and the like can be realized by a commercially available product, component, or combination of technologies. However, in the preferred embodiment of the present invention, the mobile terminal device 20 is built in the form of an application software in a smart mobile device, such as a smart phone or a tablet computer, and utilizes the smart mobile device. The processing unit, the wireless communication unit, the information output unit, the memory unit, the power supply unit, and the like that have been equipped, perform the operations required by the mobile terminal device 20 to output the processing result. This form of mobile terminal equipment architecture and operation methods are well known in the industry, and details are not required to be described here.

According to a preferred embodiment of the present invention, the mobile terminal device 20 constructs a motion monitoring program. After the computing device 21 is executed, the computing device 21 can be caused by the computing device 21 according to the sensing result data received by the wireless communication device 22. Judging, producing a judgment result.

In most embodiments of the present invention, the computing device 21 performs the determination by the motion monitoring program, that is, the determining rule included in the motion monitoring program includes: identifying the sensing result data according to a signal pattern identification rule. At least one type of exercise represented. This type of exercise includes types of exercise such as walking, running, and cycling. According to a motion state recognition rule, based on the identified motion type, the state of the motion represented by the sensing result data is determined. The state of motion includes states defined by the pitch, number of steps, and distance of a particular type of motion. According to a motion state display rule, the judgment result of the motion state is displayed on the information output device. Usually, the displayed information is the information of the motion state, the stride frequency, the number of steps and the distance represented by a series of successive sensing results.

As described above, the information output device 23 is at least one of a sound output device and a video output device. When the information output device 23 is a sound output device, the information output device displays the sound information. When the information output device 23 is the video output device, the information output device displays characters, graphics, or animation information.

In the above-mentioned judging rule, the signal pattern identification rule includes comparing the motion type data included in the motion monitoring program according to a series of successive sensing result data, and using the motion type represented by the model with the highest approximation as critical result.

Figure 4 shows several waveforms of the results of measuring the movement of the human foot with different displacement detecting devices. In Fig. 4, Figs. 4A-4C are results obtained by placing an accelerometer on the ankle and measuring the amount of displacement of the foot when walking. 4A shows the displacement amount or component of the accelerometer in the front-rear direction of the foot, that is, the direction from the heel to the toe; FIG. 4B shows the amount of displacement of the accelerometer in the inner and outer directions of the foot, that is, the left and right direction of the foot. Or component; Figure 4C shows the displacement amount or component of the accelerometer measured in the vertical direction of the foot, i.e., the up and down direction of the foot. In addition, FIGS. 4D-4F are results obtained by placing the angular velocity on the ankle and measuring the angular velocity generated when the foot is walking. 4D shows the angle of the external rotation/inversion of the foot measured by the angular velocity meter; FIG. 4E shows the angle of the plantar/dorsi-flexion measured by the angular velocity meter. Figure 4F shows the angle of the abduction/adduction of the foot measured by the angular velocity meter. It can be observed from Fig. 4 that when the foot is performing different types of motion, the displacement values in different directions are measured by a specific displacement detector, so that a series of successive measurement results can be presented with a specific displacement pattern. . Using statistical methods, it is possible to form an array of motion types with easy distinguishing features. When judging, a series of successive sensing result data in a predetermined period is obtained, and compared with various patterns, the type of motion represented by the model with the highest degree of approximation is used as a judgment result, and the sensing result data can be correctly determined. The type of exercise represented.

In addition to comparing the patterns formed by the sensing results data, analysis of the results of the sensing results can also be used to generate useful information. Fig. 5 is a waveform diagram showing the sensing result data which is attached to the athlete's ankle when the athlete is running. The first trough in Fig. 5 can be judged as the heel strike time, and the second trough can be judged as the toe off time. The time between two time points can be judged as the "landing time" of one foot. Therefore, the period between the two heel strike times is the time required to run one step. Based on this, the number of steps per unit time can be calculated.

By comparing the sample comparison of the sensing result data and the value of the stride frequency, it is possible to correctly judge whether the exerciser is walking or running.

As for the type of exercise of riding a bicycle, it can be judged by the detection result of the angular velocity meter. Since the foot has a swivel movement when the bicycle is stepped on, the time required for each step of the pedal is approximately equal to the time required for the front and rear rings to be stepped on. When the value of the detection result of the angular velocity meter shows a regular periodic change, it can be judged as the type of exercise of riding a bicycle.

In addition to identifying the type of motion, the motion monitoring program of the present invention can be used to identify the state of motion, including the state defined by the pitch, number of steps, and distance of a particular type of motion. The method for recognizing includes extracting a specific component from the sensing result data according to the sensing result data, for example, a specific amount of axial displacement component, an angular component, etc., a value within a specific time window, and then according to the value The displayed characteristics, such as the aforementioned peak, the time point at which the peak is located, the period between the peaks, and the like, calculate the values of the step frequency, the number of steps, and the distance. The motion monitoring program may include the above or other similar determination rules, determine the type of motion represented by the sensing result data, and calculate the required motion parameters to describe the current motion state.

Since the calculation of the motion state is based on the time window, the state changes with time. The computing device 21 can successively receive the sensing result data, and subsequently generate the latest judgment result.

In addition, the motion monitoring program also includes a motion state display rule for determining information to be displayed on the information output device, that is, description information of the motion state. In a general application, the information displayed by the rule display result according to the motion state is the latest sport type information and the motion state information, that is, the step frequency, the number of steps, and the distance. For example, according to the judgment result, the following information is displayed on the image output device: "Running has been running for 20 minutes" "Step frequency: 120 steps/minute, steps: 2513 steps, distance: about 3,056 meters"

In fact, athletes in motion usually do not want the motion monitoring system to provide judgment results in the form of images. In a preferred embodiment of the invention, the information output device 23 is a voice output device, such as a voice output device including a headset. In such an embodiment, the motion state display rule judgment result is that the outputted information is output in the form of sound. For example: "You have been running for 20 minutes while running." "The current step frequency is 120 steps per minute. You have already ran 2513 steps, about 3,056 meters."

Such a voice output device and method can be achieved by using a prior art voice generating device. People in this industry are not difficult to achieve with existing technology.

Furthermore, in a preferred embodiment of the present invention, the determination rule of the motion monitoring program further includes generating at least one motion suggestion information based on the determined motion state according to a motion suggestion rule, displayed on the information output device 23. The sports construction information that the motion suggestion rule can provide may include adjustment of the pitch recommendation information, encouragement suggestion information, target type suggestion information, and comparative suggestion information, and the like.

In the above suggestion information, the adjusting step frequency suggestion information may include determining a set of ideal step frequencies suitable for different time periods according to a certain motion quantity target setting value, comparing the current step frequency with the ideal step frequency, and generating the step frequency suggestion information. . For example: "You are now a little faster, please slow down." "You are now a little slower, please speed up."

The encouragement suggestion information may include setting a value according to a certain exercise amount target, and calculating a gap between the current exercise amount and the target value when detecting that the exerciser's pitch frequency is significantly decreased, and issuing encouraging suggestion information. For example: "Don't give up, only 200 meters from the target."

The target type suggestion information may include setting a value according to a certain exercise amount target, periodically determining the difference between the current exercise amount and the target value, and issuing target type suggestion information. For example: "There is still 500 meters from the target."

The comparison type suggestion information may include taking out a specific motion quantity record value according to a certain motion monitoring record file, periodically determining the difference between the exercise step frequency, the number of steps and the distance and the recorded value, and issuing comparative suggestion information. For example: "You have improved more than yesterday. Today, we have taken 500 more steps."

The above-mentioned motion parameters, including the description of the motion type, the motion state, and the like, can be calculated according to the sensing result data of the motion sensing device 10, and the operating device 21 can obtain the relevant parameters and values by using a simple application software. The calculation and determination are performed based on the judgment rule in the motion monitoring program, and useful information is generated and displayed on the information output device 23.

In an embodiment of the present invention, a series of successive determination results and corresponding sensing result data may form a motion record file stored in the memory device 24 for describing a motion. This sports log file is still available for offline analysis or sent to a cloud server for analysis.

Moreover, in a preferred embodiment of the present invention, the mobile terminal device 20 may further include an input device 24 for the user to input at least one of the number of steps and the distance. The input device 24 is typically the touch screen or button of the mobile terminal device 20. The input target value can be applied in the above motion suggestion rule to generate various suggestion information. In one embodiment, the determination rule of the motion monitoring program further includes a motion target rule, and based on the determined motion state, determining at least one type of motion target information is displayed on the information output device. The motion suggestion information may include at least one of information from a target step and a distance from the target. For example: "Today's target is 4000 meters, and the target is 1200 meters." The judgment rule can be judged periodically to generate voice information.

Other judgment rules that can be applied to the present invention may include professional analysis judgment rules in the field of sports technology. The timing of the judgment may be timing or it may be triggered by an event. It is better to output in the form of speech, accompanying the athlete to complete the exercise.

The invention provides a novel portable motion monitoring system, which is small in size and light in weight. The motion sensing device 10 can be attached to the limb of the athlete to sense the motion of the athlete. The mobile terminal device 20 can be attached to an athlete, and provides one or a pair of earphones to output motion related information and/or suggestion information to the user. The mobile terminal device 20 can even be formed, for example, in the size of a headset, attached to the ear of an athlete. The mobile terminal device 20 can also be provided with a function of a recorder or a radio to play music, books, news, and the like from the earphone. The portable motion monitoring system proposed by the present invention may be referred to as a mobile treadmill. The treadmill's motion monitoring function can be provided without the treadmill settings. Sportsmen can also ride freely by bicycle, not limited to the gym.
