Description

A device for measuring momentum by using a wireless sensor node and a system using the same {{ENERGY EXPENDITURE APPARATUS USING WIRELESS SENSOR NODES AND SYSTEM USING THE SAME}

The present invention relates to an exercise amount measuring apparatus using a wireless sensor node and a system using the same, and more particularly, to an exercise amount measuring apparatus and a system using the same in consideration of the topographical characteristics of the movement path.

In the related art, the number of steps is measured, such as a pedometer, and then the approximate amount of motion is calculated by converting the moving distances. In recent years, the mobile communication device includes an acceleration sensor or a GPS (Global position system) function. Using the terminal, it is possible to measure the exercise amount by calculating the path, the moving speed, and the moving distance.

In the case of the conventional pedometer, not only the accuracy was lower than that of a recent GPS measuring instrument, but also the inconvenience of not considering the speed information other than the moving distance. Therefore, it was very difficult to measure calories burned from exercise.

On the other hand, even when GPS is used, location information is used, but inaccurate results are obtained because speed information calculated using a change amount of location information with respect to time is used.

In particular, the most important thing in considering the momentum will be the moving distance and the moving speed, but for the more accurate measurement, it is necessary to consider the characteristics of the path.

In other words, the space in which users exercise generally varies from the small lot of villages to the tracks and hiking trails of large lake parks, and in particular, they have different characteristics in the slope, bend, bend, and terrain of the movement path. Therefore, when measuring the amount of exercise of the user in consideration of this, more accurate measurement is possible.

However, as described above, even in the case of a conventional measuring device such as a pedometer or a location information-based measuring system such as a GPS, there is a problem in that a route characteristic of a region where the user is exercising cannot be considered, and a method for solving the problem is required.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide an apparatus for measuring the amount of exercise using a wireless sensor node reflecting the characteristics of the topographical elements in the motion path and a system using the same.

In order to achieve the above object, an exercise amount measuring system according to an embodiment of the present invention includes a wireless sensor node for transmitting a wireless signal at a predetermined time interval; A plurality of receiving nodes for receiving a radio signal transmitted from the wireless sensor node; And an exercise amount measuring device for measuring the exercise amount by comparing the exercise amount inferred using the wireless signal received by the receiving node with a preset exercise table.

In addition, the wireless sensor node, a communication module for transmitting a low power wireless signal; And a power module for supplying power to the communication module.

The exercise amount measuring apparatus records the strength of the radio signal received by each of the plurality of receiving nodes during a predetermined sampling time, and infers the movement speed for each section of the exercise path.

In addition, the exercise amount measuring apparatus may infer the movement speed for each section of the exercise path, and determine the exercise amount of the user by comparing the inferred movement speed for each section with a preset exercise table.

The exercise amount measuring device may determine the calorie consumption of the user by corresponding the determined exercise amount to a preset calorie consumption table.

The exercise amount measuring apparatus may further include a display configured to display the measured exercise amount.

The exercise amount measuring apparatus may display the measured exercise amount for each section or display the total exercise amount by calculating the total of the measured exercise amounts.

On the other hand, the exercise amount measuring apparatus according to an embodiment of the present invention for achieving the above object, the storage unit for storing a table containing a standard exercise amount on the exercise path; And an exercise amount measuring unit comparing the amount of exercise inferred using the radio signals received from a plurality of receiving nodes with the amount of exercise compared with the previously stored amount of exercise table.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a view showing a part of the configuration of the exercise amount measurement system according to an embodiment of the present invention. However, FIG. 1 illustrates only the wireless sensor node 100 and the receiving nodes 200 in the process of collecting data for measuring the exercise amount according to the movement path of the user 10, and through the collected data. With respect to the exercise amount measuring device for measuring the actual exercise amount will be described in detail with reference to FIG.

As illustrated in FIG. 1, a wireless sensor node 100 and a plurality of receiving nodes 200 may be provided to collect data for measuring an exercise amount according to a moving path of the user 10.

The wireless sensor node 100 includes a communication module for transmitting a low power wireless signal to a plurality of receiving nodes 200 established on an exercise path at regular time intervals. On the other hand, it may further include a power module for supplying power to the communication module. Here, the wireless sensor node 100 may store its own identification number, and through this, the exercise amount measuring apparatus may recognize the user 10.

On the other hand, the plurality of receiving nodes 200 are installed in the movement path of the user 10 at regular intervals, and when the wireless signal transmitted by the wireless sensor node 100 is received in the receiveable area, the strength of the received wireless signal Record it.

As shown in FIG. 1, when the user 10 moves the exercise path, each of the receiving nodes 200, that is, the receiving node i + 2, the receiving node i + 1, the receiving node i, and the receiving node i− 1, all of the receiving node i-2 receives the wireless signal from the wireless sensor node 100 worn by the user 10. However, the receiving node i + 2, the receiving node i + 1, the receiving node i, the receiving node i-1, and the receiving node i-2 will each receive radio signals of different sizes.

That is, the signal of the receiving node i close to the user 10 will be the largest, and the receiving node i + 2 or the receiving node i-2 located relatively far will receive a weaker signal than the receiving node i.

When the plurality of receiving nodes 200 records the intensity of the radio signal received during the predetermined sampling time, it may be inferred how the user 10 has moved the exercise path. That is, the user may obtain information on how fast the user has moved, rested, or walked at a particular section.

Meanwhile, the plurality of receiving nodes 200 may have a function of recognizing the identification number of the wireless sensor node 100 and storing wireless signal data transmitted for each user. Through this, when a plurality of users are traveling along the movement path at the same time, it is possible to distinguish and store the radio signals transmitted from the respective wireless sensor nodes 100.

2 illustrates data representing the strength of a signal received by the plurality of receiving nodes 200.

In FIG. 2, M wireless nodes record the strength of a wireless signal received during N sampling times, that is, the strength of a wireless signal transmitted from the wireless sensor node 100. In the graph of FIG. 2, the wireless signal strengths of the five receiving nodes illustrated in FIG. 1, that is, the wireless signal strength 210 of the receiving node i + 2, the wireless signal strength 220 of the receiving node i + 1, and the receiving node i The wireless signal strength 230 of the receiver, the wireless signal strength 240 of the receiving node i-1, and the wireless signal strength 250 of the receiving node i-2.

Referring to the graph of FIG. 2, the strength 210 of the radio signal of the reception node i + 2 is weak at first and gradually increases over time. In addition, the strength 230 of the radio signal of the reception node i tends to increase and decrease again, and the strength 250 of the radio signal of the reception node i-2 is very large at first, but gradually decreases with time. Seems.

And, it can be seen that the signal strength at each receiving node tends to increase or decrease constantly for a certain period. Through such signal data, it can be seen that the moving path of the user 10 is in the receiving node i + 2 direction from the receiving node i-2, and the moving speed is constant.

In addition, it is possible to measure the amount of exercise per section for the entire exercise path. With respect to the amount of exercise measured for each section, considering the state of the entire exercise route, that is, the elevation of the terrain or the state of the road, it is possible to measure the amount of exercise more precisely.

For example, even if there is an uphill section A and a flat section B on the exercise route, if the amount of exercise data is the same, the actual amount of exercise is weighted by giving weight to the amount of exercise in the uphill section A. Greater than).

Of course, Figure 2 assumes a simple graph for convenience of explanation, in the actual case will show a more complex aspect, even in that case may be applied to the above-described method of measuring the momentum.

FIG. 3 is a graph of the graph of FIG. 2, that is, the strengths of the radio signals received during the N samplings by the M radio receiving nodes 200 in a matrix. The intensity of the wireless signal received by the wireless reception node 200 is eventually stored as data in the form of a matrix as shown in FIG. 3 for the momentum measurement, and the stored data is transmitted to the momentum measurement device 300.

The matrix shown in FIG. 3 represents the strength of the radio signal received by the M radio receiving nodes 200 during the N samplings, and thus is represented by an M * N matrix. Comparing this with a preset standard matrix, it is possible to more precisely measure the overall momentum as well as the momentum of each section.

The exercise amount measuring apparatus 300 is configured to form an exercise amount measuring system and may be implemented as a separate server. In this case, the exercise amount measuring apparatus 300 may collect all the data representing the wireless signal strength in a matrix from the receiving nodes 200 and measure the overall amount of exercise.

In addition, the exercise amount measuring apparatus 300 may also be assumed when provided in the wireless sensor node 100 for transmitting a wireless signal. In this case, the wireless sensor node 100 may have a function of receiving a matrix of wireless signal strengths from the receiving node 200 in addition to transmitting a signal. That is, the wireless sensor node 100 may receive a matrix of wireless signal strength from the receiving node 200 and measure an overall amount of motion.

Hereinafter, referring to FIG. 4, a method of measuring the amount of exercise and calorie consumption per section by the exercise amount measuring apparatus 300 will be described.

The exercise amount measuring apparatus 300 extracts a pattern for each section using a preset standard pattern table 310. The preset standard pattern table is a table in which the amount of exercise and calorie consumption are defined in consideration of the moving speed or the movement pattern by reflecting the terrain information for each section when the user moves the exercise route for each section.

For example, the standard pattern table 310 is a table in which the amount of exercise is defined step by step in consideration of the terrain and the speed from the section 1 to the section n.

That is, when section 1 is an uphill road, the weight of the uphill road is applied to define the amount of momentum when moving at a speed of 5 m / s, moving at a speed of 10 m / s, and moving at a speed of 20 m / s. . In addition, even when the section n is flat but is sandy, the weight of the sand is also applied, and when moving at a speed of 5 m / s, moving at a speed of 10 m / s, and moving at a speed of 15 m / s, respectively. You can define it.

The standard pattern table 310 may be compared with a matrix of wireless signals representing the received movement pattern of the user 10, so that the amount of exercise of the user 10 may be determined for each section or for the entire section. This reflects the topographical characteristics of each section and enables more precise momentum measurement.

The exercise amount measuring apparatus 300 extracts the pattern 320 for each section from the preset standard pattern table 310. The section-specific pattern 320 extracted by the exercise amount measuring apparatus 300 matches the wireless signal strength matrix 340 generated through the section-specific reception pattern 330 of the user 10 to determine the section-specific amount of exercise.

That is, when the amount of exercise in the section N is measured, the actual amount of exercise is determined by matching the information indicated by the wireless signal strength matrix 340 with the standard pattern in the section N extracted from the preset standard pattern table 310. That is, the preset standard pattern table 310 summarizes the amount of exercise reflecting the topographical elements into a table, and since the exercise pattern of the user 10 can be known through the received matrix, the user 10 in the section N The momentum reflects the topographical factors.

In addition, the exercise amount measuring apparatus 300 may store data on calorie consumption corresponding to the exercise amount, and may determine calorie consumption when the exercise amount is determined in a specific section.

In addition, the exercise amount measuring apparatus 300 may include a display unit (not shown) for displaying the determined exercise amount or calorie consumption amount. The user 10 may intuitively check his or her exercise amount and calorie consumption through a display unit (not shown).

Figure 5 is a block diagram showing the configuration of an exercise amount measuring apparatus according to an embodiment of the present invention. As shown in FIG. 5, the exercise amount measuring device includes a storage 400 and an exercise amount measuring part 410.

The storage unit 400 has a function of storing the standard pattern table 310 as described above. The standard pattern table 310 includes pattern information for each section, and the pattern information for each section may include an exercise amount and calorie consumption amount corresponding to a moving speed.

As described above, the exercise amount measuring unit 410 determines the amount of exercise for each section by matching the wireless signal intensity matrix that records the exercise pattern for each section of the user 10. That is, the exercise amount measuring unit 410 extracts the pattern 320 for each section from the preset standard pattern table 310.

The exercise amount measuring unit 410 determines the amount of exercise for each section by matching the extracted section-specific pattern 320 with the wireless signal strength matrix 340 generated through the section-specific receiving pattern 330 of the user 10.

That is, when the amount of exercise in the section N is measured, the actual amount of exercise is determined by matching the information indicated by the wireless signal strength matrix 340 with the standard pattern in the section N extracted from the preset standard pattern table 310. That is, the preset standard pattern table 310 summarizes the amount of exercise reflecting the topographical elements into a table, and since the exercise pattern of the user 10 can be known through the received matrix, the user 10 in the section N The momentum reflects the topographical factors.

In addition, the exercise amount measuring unit 410 may determine the calorie consumption amount for the exercise amount determined in a specific section by using the data on the calorie consumption amount stored in the storage unit 400.

However, the exercise amount measuring device may include a display unit for displaying the exercise amount or calorie consumption amount determined by the above-described process, in addition to the configuration shown in FIG. 5. Through the display unit, the user may intuitively recognize his or her exercise amount and calorie consumption.

In addition, the exercise amount measuring apparatus may further include a communication unit for receiving data from the receiving nodes. The communication unit has a main function of receiving data from the receiving nodes, but may have a function of transmitting the determined exercise amount and calorie consumption to the outside and providing the same to the user. As a result, the user may receive the exercise amount and calorie consumption determined from the exercise amount measuring device through a portable mobile.

According to the exercise amount measuring apparatus and the system according to an embodiment of the present invention described above, it is possible to reflect the topographical characteristics of the movement path, it is possible to enable more accurate exercise amount measurement.

In addition, calorie consumption according to the amount of exercise can provide an environment that the user can intuitively recognize.

While the above has been shown and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, it is usually in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or prospect of the present invention.
