In order to accomplish the above object, the present invention provides a method for detecting the amount of milk, comprising: a first measurement step of measuring a first weight of a baby placed on a feeding cushion and applied to the feeding cushion; , The weight during the feeding of the lactating cushion during feeding is measured a plurality of times at a predetermined interval and the initial weight is compared with the weight measured during a plurality of times of breastfeeding and it is judged that an external force is applied when the weight during breast- And a measuring step of calculating.

The measurement step may include a change amount calculating step of calculating a change amount by measuring a weight during breastfeeding and comparing the initial weight or the weight during breastfeeding with the weight of the previous breastfeeding measured before the weight of breastfeeding; An external force influence judging step of judging whether the change amount is 0.5 percent or more and recognizing that the external force is an event applied to the feeding cushion if the change amount is 0.5 percent or more of the initial weight or the weight of the former breast- Thereafter, a counter step of adding a counter factor by one and a measurement end determination step of determining whether a counter factor is 3 or more are included. If the counter factor is less than 3, the change amount calculating step can be performed again.

In addition, the weight during feeding can be measured at intervals of 1 second after the start of feeding.

If the amount of change is less than 0.5 percent of the weight of the initial weight or the weight of the poultry measured before the lactation, an event occurrence confirmation step is performed to determine whether a previous event has occurred. If there is no previous event occurrence, the counter step is performed , The counter factor may be added by one.

If the amount of change is less than 0.5 percent of the initial weight or the weight of the previous feeding measured before the weight of the poultry, an event occurrence confirmation step is performed to determine whether a previous event has occurred. If there is a previous event occurrence, And an effective range determination step of determining whether the absolute value of the initial weight difference is 4 percent or less of the initial weight.

Also, if the absolute value of the weight and initial weight difference at the time of event occurrence exceeds 4 percent of the initial weight, the counter step is performed and the counter factor can be added by one.

In addition, if the absolute value of the weight and the initial weight difference at the time of event occurrence is less than 4% of the initial weight, the weight during pumping at the time of event occurrence is subtracted from the weight at the time of occurrence of all events recognized as an event before the event occurs A final weight calculation step of calculating the final weight of the event by adding the weight of the poultry measured before the occurrence of the event and the event weight change amount may be performed. Thereafter, a counter step is performed, and a counter factor can be added by one.

If the event is not generated, the effective weight, which is the sum of the initial weight and a plurality of the weights during infant feeding, is divided by the effective time which is the final counter factor value, When an event occurs, an approximation of an external force, which is a weight obtained by subtracting the final weight of the event calculated at the time of occurrence of the event, from the measured weight during the event, is obtained, and the sum of the approximate values of the external forces And calculating an average weight by dividing the effective weight by the effective time obtained by subtracting the number of times of occurrence of the event from the final counter factor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, it should be noted that the same components or parts among the drawings denote the same reference numerals whenever possible.

In the following description of the present invention, a detailed description of related arts will be omitted so as not to obscure the gist of the present invention.

1 to 3, the method for detecting the amount of milk using the load cell 130 provided in the feeding cushion 100 of the present invention is characterized in that the baby is placed on the feeding cushion 100, (S200) in which the breastfeeding mother feeds breast milk to the baby, and a weight during breastfeeding applied to the breastfeeding cushion (100) at a predetermined interval several times (S300) for comparing the initial weight with the weight measured during the plurality of times of breastfeeding, determining that an external force is applied when the weight during breastfeeding is above the threshold value, and calculating the amount of breastfeeding excluding the external force. In one embodiment of the invention, the weight during feeding is measured at intervals of one second after the start of feeding.

The measurement step S300 includes a change amount calculating step S310, an external force influence determining step S320, a counter step S330, a measurement end determination step S340, and a measurement end determination step S340.

The change amount calculating step S310 calculates the change amount by measuring the weight during breastfeeding and comparing it with the weight of the initial breastfeeding measured before the initial weight or the weight during breastfeeding.

 The external force influence determining step S320 determines whether the change amount is 0.5 percent or more of the initial weight or the weight of the previous breaststroke measured before the weight of the poultry. If the amount of change is equal to or greater than 0.5 percent of the initial weight or the weight during the pre-lactation measured before the weight during lactation, an external force is recognized as the occurrence of the event applied to the lactation cushion 100.

The term " event " refers to the fact that an unnecessary external force is applied to the feeding cushion 100, thereby causing an unintended weight increase of the feeding cushion 100 other than the initial weight and the weight increase due to the feeding amount.

In the embodiment of the present invention, as described above, the change amount of the weight to be applied to the feeding cushion 100 is calculated through the variation amount calculating step S310, and the variation amount is first If the weight is determined to be 0.5% or more of the weight measured before the lactation, the event is considered to have occurred.

The counter step S330 is performed after the external force influence determining step S320, and the counter factor is added by one. The counter factor is incremented by 1 every time a determination is made as to whether an event has occurred, whether there is an external force fluctuation, and the final weight of the event is calculated.

The measurement end determination step (S340) determines whether the counter factor is 3 or more. If the counter factor is less than 3, the change amount calculating step (S310) is performed again. When the counter factor is 3 or more, the measurement step S300 is ended, and the subsequent step is performed.

If it is determined through the external force influence determination step S320 that the change amount is less than 0.5 percent of the initial weight or the weight of the previous breaststroke measured before the weight of the poultry, an event occurrence confirmation step S350 is performed to determine whether a previous event has occurred .

If it is determined through the event occurrence confirmation step S350 that no previous event has occurred, the validity range determination step S360, the feeding amount calculation step S370, and the final weight calculation step S380, which will be described later, are not performed, (S330) is performed, and the counter factor is added by one.

This is to calculate the event weight change amount and the final weight of the event on the basis of the weight immediately before the occurrence of the event and after the occurrence of the event. The amount of change in the event weight is a value obtained by subtracting the weight during breastfeeding at the time of occurrence of all events recognized as an event before the occurrence of the event in the weight during breastfeeding at the time of occurrence of the event. The final weight of the event is a value obtained by adding the weight change of the event to the weight measured before the event occurs.

That is, when the first event is generated, the effective range determining step S360, the feeding amount calculating step S370, and the final weight calculating step S380 are not performed. After that, in the measurement end determining step S340, The validity range determining step S360, the feeding amount calculating step S370, and the final weight calculating step S380 are repeated until it is determined that the final weight calculation is completed.

On the other hand, if it is recognized through the effective range determination step S360 that the external force is changed, the counting step S370 and the final weight calculation step S380 are not performed, the counter step S330 is performed, 1 is added.

If it is recognized through the effective range determination step (S360) that the external force has changed, it is assumed that the external force has changed and it is assumed that the first event is generated. Accordingly, the event weight change amount due to the fluctuating external force and the final weight of the event are calculated based on the weight during feeding and the weight during breast-feeding measured at the time of the external force change.

This is explained in more detail as follows. An effective range determination step S360 of determining whether the absolute value of the weight during milking at the time of occurrence of the event and the initial weight difference is less than or equal to 4 percent of the initial weight is determined through the event occurrence confirmation step S350, Is performed.

If the absolute value of the weight and the initial weight difference at the time of event occurrence exceeds 4 percent of the initial weight, the counter step S330 is performed as described above, and the counter factor is added by one. When the absolute value of the difference between the weight and the initial weight difference at the time of occurrence of the event exceeds 4 percent of the initial weight, it is assumed that the external force has changed and the external force approximation and the amount of feed are not measured.

If the absolute value of weight and initial weight difference at the time of event occurrence is less than 4% of the initial weight, the weight during pumping at the time of event occurrence is subtracted from the weight during pumping at the time of occurrence of the previous event A feeding amount calculating step (S370) for calculating the weight change amount is performed.

After performing the feeding amount calculation step S370, a final weight calculation step S380 is performed to calculate the final weight of the event by adding the weight during breastfeeding measured before the occurrence of the event and the event weight change amount.

After the final weight calculation step S380 is performed, a counter step S330 is performed, and the counter factor is added by one.

In the measurement end determination step S340, if the counter factor is 3 or more, the measurement step S300 ends.

After the measurement step S300 ends, the average weight calculation step S400 is performed. When no event has occurred in the measurement step S300, the average weight is calculated by dividing the effective weight, which is the sum of the initial weight and the plurality of weights during feeding through the average weight calculation step S400, into the effective time which is the final counter factor.

When an event occurs in the measurement step S300, an external force approximation value obtained by subtracting the final weight of the event calculated at the time of occurrence of the event is obtained from the weight during the measurement of the weight during the event through the average weight calculation step S400. Then, the sum of the approximate values of the external forces is subtracted from the sum of the initial weight and the plurality of weights during lactation, and the effective weight is obtained. Finally, the average weight is calculated by dividing the effective weight by the effective time obtained by subtracting the event occurrence count from the final counter factor.

After the average weight calculation step S400, the feeding end determination step S500 is performed. In the feeding termination determination step S500, it is determined whether the effective weight is equal to the previous effective weight. If the effective weight is equal to the previous effective weight, it is determined that the feeding is completed. If the effective weight is not equal to the previous effective weight, the measurement step (S300) is performed again for continuous measurement. When the first feeding termination determination step S500 is performed, since the previous effective weight is 0, the measurement step S300 is performed again.

If it is determined in step S500 that the effective weight is equal to the previous effective weight, the measurement abnormality determination step S600 is performed.

As the external force is not repeatedly changed through the determination of the presence or absence of the measurement abnormality (S600), the final weight calculation step S380 is performed to check whether the final weight of the event has been calculated.

If it is confirmed that the event final weight is not calculated as the external force is repeatedly varied, an error indication step (S710) is performed to output an error indication to the outside.

In step S600, the final event weight, the event weight change amount, or the average weight is output to the outside in step S700.
