Hereinafter, a real-time exercise information management system according to embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1, a real-time exercise information management system 10 according to an embodiment of the present invention is shown.

The first receiving unit 110 may receive the motion data from the first device, and the second receiving unit 120 may receive the operation data from the second device.

The first receiving unit 110 and the second receiving unit 120 may include a wireless communication module for receiving wireless data transmitted from the first device or the second device. In this embodiment, the first receiving unit 110, And the second receiving unit 120 may be independent modules, but the present invention is not limited thereto. The first receiving unit 110 and the second receiving unit 120 may operate as one direct module.

The first device may be a device attached to the client and measuring motion information of the client to generate motion data, and may further include a communication module for wireless communication and a plurality of sensor modules for measuring motion information of the client.

For example, the first device may be a wearable device in the form of a wrist band attached to a client, and may include a communication module for transmitting a communication signal at a predetermined interval within the band, And an inertial measurement unit (IMU) that measures the heart rate, body temperature, and the like of the client. However, the present invention is not limited thereto.

The first device may measure motion information of the client to generate motion data, and may transmit the generated motion data to the first receiver 110 through the communication module.

The second device may include a wireless communication module and a plurality of sensor modules that are attached to the exercise device to generate operation data by measuring motion information of the exercise device, and perform communication with other communication modules.

Generally, a fitness machine provided in a fitness center can be roughly divided into an aerobic fitness machine, a weight machine, and a free weight machine.

The aerobic or aerobic machine may be a device capable of helping the aerobic exercise of the user, such as a treadmill (treadmill), a cycle, etc., and the second device may be attached to one side of the aerobic exercise device to generate the operation data of the machine . For example, in the case of a treadmill, the second device may be attached to one side of the treadmill to receive the speed, operating time, slope, virtual travel distance, etc. of the belt produced from the treadmill. The operation information of the treadmill is transmitted to the second device using a Communications Specification for Fitness Equipment (CSAFE) port, which is a common communication standard for all fitness equipments. The second device transmits operation data based on the operation information received through the CSAFE However, the present invention is not limited to this, and it is also possible to photograph the belt at a high speed using a separate image sensor provided in the second apparatus to generate operation data.

Further, the second device may be mounted on the free weight mechanism. Representative examples of free weight mechanisms are dumbbells and barbels, which may be mounted on dumbbell and barbell rods, but are not limited thereto. For example, the second device may be a cylindrical device that can be mounted on the rod portion of the dumbbell, and the speed, acceleration, etc. of the dumbbell may be measured using the inertial measurement device or the acceleration sensor, have. Further, unlike other fitness devices, the dumbbell, the barbell, and the like may further include a wireless communication module or a distance measurement module capable of generating position information at predetermined time intervals and transmitting the position information to another communication module since the position may be moved by a user But is not limited thereto.

The weight machine can be fixed to a certain place and can be a mechanism that can help the movement of specific muscles such as biceps, triceps, and rhyolite. A desired motion effect may be obtained by adjusting the number of weight of the user, and the second device may be mounted on the weight, but the present invention is not limited thereto. For example, a tag including weight information may be attached to each weight, and the NFC module included in the second device attached to the pin for controlling the weight of the weight may recognize the position and tag of the weight control pin Weight information can be measured corresponding to the position where the pin is inserted.

As such, the second device can be varied in size and shape corresponding to various exercise devices, and can generate operation data from the exercise device using the plurality of sensor modules included in the second device, To the second receiver (120).

The controller 200 may determine whether the motion data is matched with the motion data based on the correlation between the motion data received by the first receiver 110 and the motion data received by the second receiver 120. [

For example, it is possible to calculate the similarity or correlation coefficient between two data by comparing the reception timing, duration, ending point, and pattern of the movement data with the reception timing, duration, ending point, and pattern of the movement data, If the correlation coefficient is included in the critical section for a predetermined time or more, it is determined that the two data are correlated with each other, so that the two data can be matched.

The meaning of matching the motion data with the motion data means that the client that transmitted the motion data or the first device is exercising using the exercise device or the second device that transmits the motion data. That is, when the starting point of the motion data is similar to the starting point of the motion data and the pattern amount of the motion data is varied corresponding to the variable amount of the motion data pattern, it is possible to guess that the client is using the mechanism to exercise, The controller 200 can determine the correlation based on the correlation coefficient or similarity between the motion data and the motion data.

In some other embodiments, the controller 200 may determine whether to match each location data received from the first or second device further on. For example, when a plurality of clients, i.e., a plurality of first devices, are located near one exercise device, i.e., the second device, a determination criterion may be required as to which client uses the exercise device. At this time, the control unit 200 may match the first device, which is positioned at the closest position with reference to the position data of the second device received from the second device, with the second device. In other words, the module or the server provided with the real-time motion information management system 10 according to the present embodiment may further receive a plurality of position data and determine whether the received position data is matched based on the received data. However, The control unit 200 may further perform a preprocessing process of filtering the exercise data based on the usage candidate list generated from the second device and selectively compare only the filtered exercise data with the operation data.

The processor 300 may compare the motion data and the operation data matched by the controller 200 with the historical data to calculate the similarity and generate the fitness information based on the history data in which the similarity is maintained over the predetermined reference time. That is, the processor 300 may compare the matched motion data and the motion data with previously learned history data, and compare the matched pattern with the learned pattern to extract a similar pattern. For example, when the motion data having the first pattern and the motion data having the second pattern are matched from the control unit 200, the processing unit 300 searches the database unit (not shown) for the history data, It is possible to retrieve the similar data in which the two patterns are matched. When the exercise data of the client is the first pattern and the exercise apparatus using the fitness pattern forms the second pattern, it is possible to calculate the kind, strength, pattern, number of times, amount of heat consumed and time of exercise from the stored history data, Information can be generated.

In some other embodiments, the processing unit 300 may directly calculate fitness information from matched motion data and motion data. That is, the fitness information can be directly calculated on the basis of information such as acceleration, angular velocity, posture, and time included in the exercise data, and variables such as acceleration, speed, and time included in the exercise data.

The transmitting unit 400 may transmit the generated fitness information to the client device or the external server, but the present invention is not limited thereto and may be further transmitted to the first device or the second device. As described above, the fitness information includes the type, frequency, intensity, amount of activity, energy consumption, time, pattern, and the like of the exercise, and various exercise-related contents can be generated using the received fitness information.

Referring to FIG. 2, embodiments for receiving motion data and motion data in the extended system of FIG. 1 are shown.

As shown, the real-time exercise information management system 10 according to the present embodiment can construct an extended system using the first device 20, the second device 30, and the antenna module 40 . As described above, the first device 20 may be attached to the client and generate the exercise data based on the exercise information of the client. The second device 30 may be mounted on one side of the exercise device, The operation data can be generated on the basis.

The motion data generated from the first device 20 and the motion data generated from the second device can be directly transmitted to the real-time motion information management system 10 according to the present embodiment, but the present invention is not limited thereto, 40).

The antenna module 40 may be disposed within a predetermined radius and may have a function of relaying data from the first device 20 or the second device 30 located outside the communication radius of the system 10 according to the present embodiment And may further measure the distance information of the first device 20 or the second device 30.

Referring to FIG. 3, there is shown an embodiment for positioning location information of a first device in the extended system of FIG.

As shown in the figure, the mobile communication terminal includes a first device 20, a plurality of second devices 30_1, 30_2, 30_3, and 30, a plurality of antenna modules 40_1, 40_2, 40_3, The gateway or server 10 may be connected to a wireless communication network and may exchange data with each other using, for example, Zigbee communication.

At this time, the position information of the first device 20 can be measured from the plurality of antenna modules 40. For example, the first antenna module 40_1 may transmit a distance measurement signal and receive a response signal from the first device 20 receiving the distance measurement signal. The first antenna module 40_1 can measure the distance information of the first device 20 using the time difference between the transmission time of the distance measurement signal and the reception time point of the response signal and the antenna modules 40_2 and 40_3, The distance information with respect to the first device 20 can be measured in the same manner. Three different distance information measured from the plurality of antenna modules 40 is received by the gateway or the server 10, and based on the initial position coordinates of the plurality of antenna modules 40 and a plurality of distance information, The position data of the first device 20 can be calculated.

In some other embodiments, the plurality of antenna modules 40 may further measure distance information to the plurality of second devices 30, and the server 10 may further calculate position data of the second device 30 based thereon And may further measure the distance information of the first device 20 from the plurality of second devices 30. Further, the plurality of second devices 30 may further measure the mutual distance information, and in some other embodiments, the second device 30 may have the initial position coordinates.

The position data of the first device 20 or the second device 30 measured by the server 10 can be used to determine the exercise device being used by the client attaching the first device 20. [ For example, when the position data of the first device 20, that is, the position coordinate, is similar to the position data of the specific second device 30_2, the motion data received from the first device 20 is transmitted to the specific second device 30_2 To the operation data received from the mobile communication terminal.

Referring to Fig. 4, an example of determining the usage candidate group of Fig. 1 is shown. As described above, the control unit according to the present embodiment can determine whether to match based on the position data of the first device and the position data of the second device. However, when there are a plurality of first devices 20_1, 20_2, 20_3, and 20 having position data similar to the position data of the second device 30, it is necessary to select an appropriate candidate group to improve the data processing speed .

Accordingly, the second device 30 can determine the use candidate group using the received signal strength indicator (RSSI) of the communication signal received from the first device 20. [ The first device 20 can transmit a communication signal at a predetermined time interval using a communication module and can receive a communication signal from the second device 30, 30 can be calculated. In general, the intensity of the communication signal is attenuated in proportion to the distance, so that the approximate separation distance can be calculated using this characteristic.

Further, the second device 30 sets the reference radius, and can determine the first devices 20_1 and 20_2 located within the reference radius based on the separation distance as the use candidate group. The use candidate group can be updated at predetermined time intervals, and the use candidate group can be transmitted to a control unit (not shown) included in the server 10. [ The control unit (not shown) filters the motion data except for the motion data received from the first apparatuses 20_1 and 20_2 included in the use candidate group and compares the motion data with the motion information of the second apparatus 30, Accuracy can be improved.

Referring to FIG. 5, an example of a data processing flow of a real-time exercise information management system according to embodiments of the present invention is shown.

First, motion data may be received from a first device attached to the client, and operational data may be received from a second device attached to the exercise device. The motion data and the motion data may be separately received by a separate receiving unit, or both the motion data and the motion data may be received by one receiving unit.

Further, distance information of the first device or the second device can be further received from the plurality of antenna modules, and the position data of the first device and the second device can be calculated using the distance information.

In some other embodiments, a use candidate group may be further received from the second device. The second device may generate and transmit a usage candidate group that is a list of first devices located within a reference radius based on the RSSI of the communication signal received from the first device.

The control unit may filter the exercise data based on the position data or the use candidate group (S11). For example, some first devices at positions close to the position data of the second device may be selected as the candidate group, and the first device included in the use candidate group may be selected as the candidate group, but the present invention is not limited thereto, The motion data of all the first devices may be selected as the candidate group.

The motion data of the selected first device may be compared with the motion data of the second device to calculate the correlation between the motion data and the motion data (S12). That is, the correlation coefficient or the similarity can be calculated using the reception time, interval, pattern, etc. of the movement data and the movement data. If the correlation coefficient or the similarity is included in the critical interval longer than the reference time, (S13). If the exercise data and the exercise data are matched, the server can determine that the client that transmitted the exercise data is using the fitness equipment.

The similarity can be calculated by comparing the matched motion data and the motion data with the history data (S14). The pattern of the exercise data and the pattern of the operation data generated corresponding thereto can be searched for data having a similar pattern among the stored history data, and the fitness information can be generated on the basis of the retrieved data (S15). The fitness information may be information such as type, number of times, intensity, amount of activity, amount of heat consumed, time, pattern, etc. according to the exercise information of the client.

Finally, the generated fitness information may be transmitted to the client device or the external server (S16) and further transmitted to the first device or the second device.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
