1 is a view illustrating that a weight measuring device 10 according to an embodiment of the present invention is installed on a hip seat 70 for infants and toddlers, and FIG. 2 is a hip seat 70 for infants according to an embodiment of the present invention. It is a flow chart of the weight measurement method used.

In general, the hip seat 70 for infants and toddlers is provided with a shoulder strap so that an adult can wear the shoulder strap and seat the infant on the mold part 75 of the hip seat 70 so that both adults and infants can take a comfortable posture.

FIG. 1 shows as an example that the weight measuring device 10 is installed on the upper part of the mold part 75 in which the mold is accommodated in the hip seat 70 .

In addition, in FIG. 1 , the body weight measuring device 10 is shown in internal transmittance to show the configuration of the first load cell 20 and the second load cell 25 .

Referring to FIG. 1 , the weight measuring device 10 is installed on the upper part of the mold part 75 and measures the weight of the infant seated on the upper surface of the mold part 75 , the first load cell 20 and the second load cell 25 . is measured and transmitted to the terminal 40 through the Bluetooth communication method.

The weight measurement method using the hip seat 70 for infants and toddlers according to an embodiment of the present invention is performed by a computer, and the computer may be implemented with the terminal 40 and the server 50 .

In addition, in the embodiment of the present invention, being performed by the terminal 40 means being driven through a service application provided by the server 50 .

Accordingly, the pre-setting is completed by the guardian of infants and toddlers installing the service application in the terminal 40 and pairing the terminal 40 and the Bluetooth communication of the weight measuring device 10 .

Then, when the guardian places the infant on the hip seat 70, the weight measuring device 10 measures the infant's weight and transmits the measured value to the terminal 40, and thereafter, the terminal 40 or the server 50 The calculator 60 calculates the exact weight of the infant by using the measurement value received from the weight measuring device 10 .

Hereinafter, with reference to FIG. 2, this will be described in more detail.

The terminal 40 receives a plurality of measured values measured from the weight measurement device 10 installed on the hip seat 70 for infants and toddlers. (Step S100)

At this time, since the weight measuring device 10 includes the first load cell 20 and the second load cell 25, the weight of the infant is measured using the two load cells.

In addition, since the weight value measured once is inaccurate due to the characteristics of the hip seat 70 , the weight measuring device 10 is repeatedly measured a plurality of times, for example, 20 to 30 times for 5 seconds, and pairing it It is transmitted to the terminal (40).

At this time, since the weight is measured through the first load cell 20 and the second load cell 25 as described above, the weight measurement value of each round consists of two measurement value sets.

Then, the weight measuring device 10 is turned on when it is detected that the infant is seated on the hip seat 70, starts to measure the weight, and measures the weight of the infant several times for a certain period of time, and the terminal 40 It operates in such a way that it is turned off after being provided as

In an embodiment, the weight measuring device 10 may receive a re-measurement request signal when the weight calculation fails in the terminal 40 or the server 50, so that the turn-on state is maintained even after measuring the weight of the infant multiple times. After maintenance, when a weight calculation completion signal is received from the terminal 40 or the server 50, it may be turned off.

Also, according to an embodiment, when receiving a weight measurement request signal from the terminal 40 , the weight measurement apparatus 10 is turned on to measure the weight of the infant.

Due to the nature of the hip seat 70, if the infant is excessively leaning on the parent's body or the left and right balance is severely disturbed, an error may occur in the measurement itself, so the server 50 transfers the infant to the hip seat 70 through the service application. ) can be provided with a guiding video guiding the method of being seated.

Therefore, the guardian executes the service application installed in the terminal 40, checks the guiding image provided on the screen, and places the infant on the hip seat 70 according to the guiding image.

In step S100, the terminal 40 receives the set of measured values measured from the first load cell 20 and the second load cell 25 a plurality of times, but included in the set of measured values more than a certain number of times among the set of measured values received a plurality of times. When the measured values of the first load cell 20 and the second load cell 25 differ by more than a threshold ratio, the infant's posture correction request message may be provided to the terminal 40 .

More specifically, it is helpful for accurate weight measurement that the measured values of the first load cell 20 and the second load cell 25 are similar, but the infant is incorrectly seated on the hip seat 70 and the first load cell 20 If there is too much difference between the two values measured by the and the second load cell 25, it may cause an error in the weight value measurement.

The calculator 60 calculates an average value of a plurality of measured values received from the weight measuring device 10 . (Step S200)

The calculation unit 60 calculates an additional correction value according to the gender and number of days of birth of the infants to be applied to the average value calculated in step S200 using the standard growth chart data of infants and toddlers and the actual measurement data of a plurality of infants stored in the database. (Step S300)

An additional correction value for the infant is calculated according to the infant's gender and birth date. (Step S300)

The calculator 60 calculates a corrected weight value by adding the calculated average value and the additional correction value. (Step S400)

The error that occurs depending on the position and posture where the infant is seated on the hip seat 70 varies, but the error that occurs also varies depending on the gender, number of days of birth, etc. of the infant, so the calculation unit 60 considers this An additional correction value is calculated, and an additional correction value is applied to an average value obtained by using the measurement value received from the weight measurement device 10 to obtain a corrected weight value.

In more detail, the calculator calculates an additional corrected value according to the gender and number of days of birth of the infant by using the standard growth chart data of infants and toddlers and the actual measurement data of a plurality of infants stored in the database.

At this time, standard growth chart data created by the Korea Centers for Disease Control and Prevention is stored in the database of the server. In addition, the database of the server stores actual data on the weight of a large number of infants and toddlers according to gender and various birth days.

Therefore, the calculator can calculate the additional correction value according to the gender and number of days of birth of the infant using the standard growth chart data and the actual measurement data stored in the database as described above.

In this case, the method of calculating the additional correction value may be implemented in various ways, for example, the additional correction value may vary according to the average value calculated in step S200 .

In addition, the learned and built additional correction value calculation algorithm uses the standard growth chart data of infants and the actual measurement data of a large number of infants and toddlers stored in the database to calculate additional correction values according to the gender and number of days of birth of the infant.

The calculation unit 60 builds a weight calculation model that has been tested and learned a number of times for various cases, and calculates the above-described additional correction value using this model.

As such, the corrected weight value calculated through steps S100 to S400 requires the premise that the weight of the infant seated on the hip seat 70 is accurately measured.

Hereinafter, a process of verifying whether the multiple measurements measured by the weight measuring device 10 are correct measurements will be described.

After step S400, the calculation unit 60 calculates the expected weight value of the infant by using the expected weight calculation algorithm. (Step S500)

When the difference between the calculated predicted weight value and the corrected weight value is less than or equal to the threshold value, the calculator 60 determines the corrected weight value as the final value, and provides it through the service application of the terminal 40 .

Conversely, when the difference between the calculated expected weight value and the corrected weight value is equal to or greater than a threshold value, the calculator 60 determines that the measured value measured by the weight measurement device 10 is incorrect, and provides the service of the terminal 40 . Provides notification of measurement failure through the application. (Step S600)

Accordingly, the guardian may check the measurement failure notification provided to the terminal 40 and select a re-measurement button to control the weight measurement device 10 to measure the infant's weight again.

Let us explain the estimated weight calculation algorithm.

① If there is a previous measurement of the infant or toddler

The calculator 60 calculates an expected weight value A from the current date in consideration of one or more previous measurement values of the corresponding infant and the weight increase rate of the corresponding infant.

The calculator 60 calculates, as the average value B, the difference between the average weight values of the infants and toddlers based on the number of birth days of the infants at the time of measuring one or more previous measurement values of the corresponding infants and toddlers and each previous measurement value.

The calculator 60 calculates an average weight value C of infants and toddlers corresponding to the current birth days of the corresponding infants and young children.

Then, the calculator 60 calculates the current expected weight value of the infant using Equation (1).

② If there is no previous measurement value for the infant or toddler

The calculator 60 determines the average weight value of infants and toddlers corresponding to the current number of birth days of the infant as the expected weight value of the infant.

In this case, the terminal 40 may store the measured value of the infant's weight in the terminal 40's own storage space, or may transmit it to the server 50 and store it.

In addition, although the calculation unit 60 has been described as a component of the terminal 40 in the above-described embodiment of the present invention, it may also be a component of the server 50 .

For example, the terminal 40 is paired with the weight measuring device 10 through Bluetooth to receive a measurement value, transmit it to the server 50, and then the calculator 60 of the server 50 performs the above-described calculation process. , and may provide a final value to the terminal 40 .

The implementation of the invention as described above can be easily selected by the implementer according to each situation.
