Summary of the Invention

Problems to be Solved by the Invention

[0006] Although Patent Document 1 can measure the weight of an infant, it cannot store the weight and there is no description about the growth record of the infant.

[0007] Although Patent Document 2 describes storing measured weight in chronological order, for example, when a father measures his weight, he must press the father's input button on the target weight input means at the beginning of the measurement. This requires operations tailored to the person being measured before the measurement is taken. Thus, the scale described in Patent Document 2 is not intended for measuring the weight of infants, and when measuring the weight of an infant, it is assumed that a parent or guardian will operate the scale while holding the infant. In such cases, performing multiple operations to measure according to the person being measured, as described in Patent Document 2, is not convenient for the user.

[0008] Therefore, the present invention aims to provide a weight measuring device, a weight measuring system, a weight measuring method, and a weight measuring program that can measure the weight of an object to be measured with simple operation. [Means for solving the problem]

[0009] A weight measuring device according to a first aspect of the present invention is a weight measuring device for measuring the weight of an object to be measured, comprising: a storage means for storing the measurement results of the registered object to be measured in chronological order; and a notification means for notifying the start of weight measurement by turning on the power if there is one registered object to be measured stored in the storage means, and for notifying the selection of the registered object to be measured for weight measurement by turning on the power if there are two or more registered objects.

[0010] With this configuration, if there is only one registered object to be measured, the weight of the object can be measured simply by turning on the power of the weighing device. A case where there is only one registered object is, for example, when the weighing device is used primarily to measure the weight of a single infant. This allows the user of the weighing device to measure the weight of the object with simple operation.

[0011] A second aspect of the present invention is a weight measuring device according to the first aspect, wherein the notification means may provide notification prompting the user to register the object to be measured if the object to be measured is not registered in the storage means. With this configuration, registration of the object to be measured is required for weight measurement, so the user can be made to habitually record weight measurements.

[0012] A third aspect of the present invention is a weight measuring device of the first or second aspect, which may include a difference calculation means for calculating the difference between two consecutive weight measurements of the object to be measured. With this configuration, the user can easily find out the difference between consecutively measured weights.

[0013] A fourth aspect of the present invention is a weight measuring device according to any one of the first to third aspects, wherein, if the number of registered objects is two or more, the notification means may first notify the user of a pre-set object from among the registered objects to be measured, as a selection of the registered object to be measured for weight measurement. With this configuration, even if the registration order is later, weight measurement can be performed with fewer operating steps, thereby improving user convenience.

[0014] A fifth aspect of the present invention is a weight measuring device according to any one of the first to fourth aspects, wherein the object to be measured is a human infant, and the device is equipped with a tray on which the infant is placed.

[0015] A sixth aspect of the present invention is a weight measuring system comprising a weight measuring device and an information processing device for measuring the weight of an object to be measured, wherein the weight measuring device includes notification means for turning on the power to notify the start of weight measurement when there is one registered object to be measured, and for turning on the power to notify the selection of a registered object to be measured for weight measurement when there are two or more registered objects, and communication means for transmitting the weight measurement result of the object to be measured to the information processing device, wherein the information processing device stores the measurement results received from the weight measuring device in chronological order for each registered object to be measured. With this configuration, a user of the weight measuring device can measure the weight of an object to be measured with simple operation.

[0016] In the seventh aspect of the present invention, the weight measurement system is a weight measurement system according to the sixth aspect, and the notification means may notify the information processing device that the weight measurement result from the weight measurement device has not been transmitted to the information processing device for a predetermined number of days or more. This configuration makes it possible to encourage the user to make a habit of recording weight on a daily basis.

[0017] An eighth aspect of the present invention is a weight measuring system for a weight measuring device that measures the weight of an object to be measured, comprising: a first step in which, when the power of the weight measuring device is turned on, a determination means determines the number of registered objects to be measured; and a second step in which, if there is one registered object to be measured, the start of weight measurement is notified, and if there are two or more registered objects, the power is turned on to notify the notification means of the selection of a registered object to be measured whose weight is to be measured. With this configuration, the user of the weight measuring device can measure the weight of an object to be measured with simple operation.

[0018] The weight measurement program according to the ninth aspect of the present invention causes a computer included in a weight measuring device that measures the weight of a measurement target to execute a first step in which a determination means determines the number of registered measurement targets when the power of the weight measuring device is turned on, and a second step in which when the number of registered measurement targets is one, a notification means is notified of the start of weight measurement, and when the number of registered measurement targets is two or more, the notification means is notified of the selection of the registered measurement target for which weight is measured by turning on the power. According to this configuration, the user of the weight measuring device can measure the weight of the measurement target by a simple operation.

Effects of the Invention

[0019] According to the present invention, the weight of a measurement target can be measured by a simple operation.

Embodiments for Carrying Out the Invention

[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiments described below are examples of implementing the present invention and do not limit the present invention to the specific configurations described below. In implementing the present invention, specific configurations according to the embodiments may be appropriately adopted.

[0022] Figure 1 is a schematic diagram of the weight measurement system 10 of this embodiment. The weight measurement system 10 comprises a weight measuring device 12, a terminal device 14, and a server 16.

[0023] The weight measuring device 12 is a device for measuring the weight (body weight) of an object to be measured. In this embodiment, the weight measuring device 12 is, as an example, a baby scale equipped with a tray 20 on which the infant is placed, with the object to be measured being a human infant. The tray 20 is, for example, curved from the edge towards the center or box-shaped to prevent the infant from falling out even if the infant moves.

[0024] The weight measuring device 12 is equipped with a display 22 and buttons 24 on its front. The display 22 functions as a display means for showing various information and a notification means for providing various notifications to the user. The buttons 24 are operated by the user, and as an example, buttons 24A, 24B, and 24C are provided.

[0025] Button 24A is a button 24 for turning on the power of the weight measuring device 12. Button 24B is a button 24 for turning off the power of the weight measuring device 12. Button 24C is a button 24 for operating various functions of the weight measuring device 12. For example, by repeatedly pressing button 24C, the previously measured weight (body weight), the previously measured amount of milk, etc., can be switched and displayed on the display 22. Also, for example, by long-pressing button 24C, various settings such as setting the number of registrations can be performed.

[0026] The weight measuring device 12 in this embodiment stores the measured weight and transmits it to the server 16 via the terminal device 14. Communication between the weight measuring device 12 and the terminal device 14 is performed, for example, by a wireless communication standard with a narrow communication range, such as BLE (Bluetooth Low Energy).

[0027] The terminal device 14 is an information processing device capable of sending and receiving data between the weight measuring device 12 and the server 16, and is, for example, a smartphone or tablet terminal device. In this embodiment, the terminal device 14 has an application (hereinafter referred to as the "measurement app") installed for receiving measurement results from the weight measuring device 12 and sending the measurement results to the server 16. The measurement app also provides various notifications to the user regarding the weight measuring device 12.

[0028] In the embodiments described below, an example is disclosed in which measurement results are transmitted from a terminal device 14 on which the measurement application is installed to a server 16, but this is not necessarily the case. For example, the terminal device 14 on which the measurement application is installed may also function as the server 16. In that case, the measurement results, milk intake amount, etc., received by the measurement application may be stored in the memory area of ​​the terminal device 14. In other words, the "information processing device" in the claims may be implemented by the terminal device 14. It goes without saying that the description of the embodiments below does not exclude the possibility that the configuration of the present invention is implemented solely by the weight measuring device 12. That is, the configuration implemented by the terminal device 14 described in the embodiments below may also be implemented by the weight measuring device 12.

[0029] The user registers the object to be measured with the weight measuring device 12 using the measurement application. The user can also use the measurement application to read and check the changes in measurement results over time stored on the server 16. The measurement results that can be checked using the measurement application include not only the measurement results of the object currently registered with the weight measuring device 12, but also the measurement results of objects that were registered in the past.

[0030] Server 16 stores the measurement results from the weight measuring device 12 received via the terminal device 14. Server 16 also transmits the weight measurement results to the terminal device 14 upon request from the measurement application running on the terminal device 14, and displays them on the terminal device 14's display 22. Furthermore, Server 16 receives and stores user information such as the name, gender, height, and date of birth of the person being measured from the terminal device 14.

[0031] The terminal device 14 may temporarily store the measurement results from the weight measuring device 12. For example, if the communication between the server 16 and the terminal device 14 is poor, the terminal device 14 stores the measurement results from the weight measuring device 12, and after the communication between the server 16 and the terminal device 14 improves, the terminal device 14 sends the measurement results to the server 16. After sending the measurement results to the server 16, the terminal device 14 deletes the measurement results from the terminal device 14.

[0032] In this embodiment, the weight measuring device 12 notifies the start of weight measurement by turning on the power when there is only one registered object to be measured, and notifies the selection of the registered object to be measured by turning on the power when there are two or more registered objects. As a result, the weight measuring device 12 of this embodiment can measure the weight of an object to be measured with simple operation.

[0033] In this embodiment, the notification content is displayed on the display 22 as an example, but is not limited to this. The weight measuring device 12 may also be equipped with a speaker, and the notification content may be output by sound and voice from the speaker. Alternatively, notification may be provided by a combination of display on the display 22 and output from the speaker.

[0034] Figure 2 is a functional block diagram relating to the various functions of the weight measuring device 12 of this embodiment. The weight measuring device 12 includes a display 22 and buttons 24, as well as a weight measuring unit 30, a registration unit 32, a registration count determination unit 34, a notification processing unit 36, a difference calculation unit 38, a storage unit 40, and a communication unit 42. The various calculations in the weight measuring device 12 may be performed, for example, by the CPU (Central Possessing Unit) of the weight measuring device 12, or they may be implemented by individual hardware such as an ASIC (Application Specific Integrated Circuit).

[0035] The weight measuring unit 30, for example, is equipped with a load cell for measuring the weight of an object placed on the tray 20. The load cell consists of a metal strain element that deforms in response to a load, and a strain gauge attached to the strain element. When the object to be measured is placed on the tray 20, the load of the object causes the strain element of the load cell to bend and the strain gauge to expand and contract. The resistance value (output value) of the strain gauge changes in accordance with this expansion and contraction. The weight measuring unit 30 then calculates the weight from the difference between the output value (zero point) of the load cell when no load is applied and the output value when a load is applied.

[0036] The registration unit 32 registers the object to be measured. The registration operation is performed using the terminal device 14.

[0037] The registration count determination unit 34 determines the number of items to be measured for the weight measuring device 12 when the power to the weight measuring device 12 is turned on.

[0038] The notification processing unit 36 ​​controls the display 22 to display various notifications related to weight measurement, etc. In this embodiment, if there is only one registered object to be measured, the notification processing unit 36 ​​notifies the start of weight measurement by turning on the power, and if there are two or more registered objects, it displays the selection of the registered object to be measured on the display 22 by turning on the power.

[0039] The difference calculation unit 38 calculates the difference between two consecutive weight measurements of the object to be measured.

[0040] The memory unit 40 stores programs for executing various functions of the weight measuring device 12, user information, and the weight of registered objects being measured in chronological order.

[0041] The communication unit 42 transmits and receives data to and from the terminal device 14. In this embodiment, the communication unit 42 communicates with the terminal device 14 using BLE (Bluetooth Low Energy), a wireless communication standard with a narrow communication range, as an example, but is not limited to this, and wireless communication may be performed using other standards.

[0042] Figure 3 is a flowchart showing the flow of the registration process for the object to be measured to the weight measuring device 12 of this embodiment.

[0043] First, in step 100, the user launches the measurement application installed on the terminal device 14.

[0044] In the next step 102, the measurement application determines whether the terminal device 14 and the weight measuring device 12 are already paired. If the determination is positive, the process proceeds to step 106; otherwise, it proceeds to step 104. Pairing refers to the process of linking the terminal device 14, on which the measurement application is installed, and the weight measuring device 12 so that data can be sent and received. The user can also confirm whether or not pairing has been achieved by checking whether or not an icon indicating pairing has been displayed on the measurement application screen.

[0045] In step 104, the user performs a pairing process between the terminal device 14 and the weight measuring device 12 via the measurement application, and then proceeds to step 106. The pairing process is performed, for example, by enabling BLE communication on the terminal device 14 and then long-pressing a predetermined button 24 on the weight measuring device 12.

[0046] In step 106, the user enters user information of the person to be measured via the measurement app. User information includes name, gender, height, and date of birth, as described above. In addition, common information regarding the use of the weight measuring device 12, such as the region in which the weight measuring device 12 will be used, may also be set.

[0047] In the next step, 108, the user enters their personal number via the measurement app. The personal number is a registration number, and as an example, a number from 1 to 5 is displayed on the measurement app (terminal device 14). This allows the user to determine whether each registration number has been used or not, and the user enters their personal number by selecting one of the registration numbers. There is a limit to the number of registrations; for example, the limit for the number of registrations is 5.

[0048] In the next step 110, the user information and personal number entered in steps 106 and 108 are transmitted from the terminal device 14 to the weight measuring device 12, and the registration unit 32 stores them in the storage unit 40 of the weight measuring device 12, thereby completing the registration process. The user information and personal number are also transmitted from the terminal device 14 to the server 16 and stored in the storage unit of the server 16. In addition, the date, time, region, etc. may be set in the weight measuring device 12 along with the registration of the user information and personal number.

[0049] Figure 4 is a flowchart showing the flow of the weight measurement process of the object to be measured using the weight measuring device 12 of this embodiment.

[0050] First, in step 200, the user presses button 24A to turn on the power to the weight measuring device 12.

[0051] In the next step 202, the registration count determination unit 34 determines whether or not there is a registered subject in the memory unit 40. If the determination is positive, the process proceeds to step 208; if the determination is negative, the process proceeds to step 204.

[0052] In step 204, the notification processing unit 36 ​​notifies the user that the person being measured is not registered by displaying this information on the display 22.

[0053] In the next step, 206, the user performs the registration process described in steps 106 to 110 via the measurement app and proceeds to step 212. In this way, the weight measuring device 12 of this embodiment has a display 22 that prompts the user to register the object to be measured if there is no registration of the object to be measured in the memory unit 40. As a result, since registration of the object to be measured is required for weight measurement, it becomes possible to encourage the user to make daily recording of weight measurements a habit.

[0054] In step 208, which is reached if the result in step 202 is positive, the registration count determination unit 34 determines whether the number of registrations is one. If the result is positive, the process proceeds to step 212; if the result is negative, the process proceeds to step 210.

[0055] In step 210, the personal number is displayed on the display 22, prompting the user to select a personal number, and the process proceeds to step 212. The selection of the personal number is done by repeatedly pressing the button 24. In other words, in step 210, the notification processing unit 36 ​​notifies the user that a personal number selection is required by displaying the personal number on the display 22.

[0056] The personal numbers displayed on the display 22 do not necessarily have to be in ascending or descending order. If there are two or more registered personal numbers, the personal number of one of the registered objects to be measured may be displayed first on the display 22 as a selection of the registered objects to be measured. For example, if "2" is selected as the personal number in advance, "2" will be displayed first on the display 22. This allows for weight measurement of objects associated with personal numbers that are registered later, for example, those with a high measurement frequency, with fewer operating steps, thereby improving user convenience. Furthermore, the process is not limited to the user selecting and setting the personal number to be displayed first on the display 22. For example, the measurement frequency of each personal number may be stored in the storage unit 40, and the personal number with the highest stored measurement frequency may be set to be displayed first on the display 22. In addition, for example, the storage unit 40 may store measurement trends such as measurement time and measurement frequency for each personal number, and the personal number based on the time the user turned on the power of the weight measuring device 12 and the measurement trend may be set to be displayed first on the display 22.

[0057] In step 212, the display 22 displays an indication that weight measurement is possible (hereinafter referred to as the "measurement start indicator") to inform the user that weight measurement is possible. The measurement start indicator is, for example, "0g".

[0058] In the next step 214, the user places the object to be measured on tray 20, and the weight of the object is measured.

[0059] In the next step 216, the storage unit 40 stores the measurement data, which associates the measurement result with user information and the measurement date and time, and the body weight measurement process ends.

[0060] As described above, in this embodiment, if there is only one registered object to be measured stored in the memory unit 40, the display 22 notifies the user to start measuring the weight by turning on the power. If there are two or more registered objects, the display 22 notifies the user to select an object to be measured from among the registered objects to be measured by turning on the power.

[0061] As a result, the weight measuring device 12 of this embodiment can measure weight simply by turning on the power when there is only one registered object to be measured. A case where there is only one registered object is, for example, when the weight measuring device 12 is used at home to measure the weight of an infant. In most households with infants, there is only one infant, and when measuring the infant's weight, it is assumed that the parent will operate the weight measuring device 12 while holding the infant. In such cases, the weight measuring device 12 of this embodiment allows the infant's weight to be measured with the minimum necessary operation, specifically by turning on the power, and can also store the weight in chronological order in association with the infant. In other words, in such cases, the weight measuring device 12 of this embodiment can eliminate unnecessary selection operations by the user at the start of measurement. On the other hand, in cases where there are multiple infants in the household, such as twins, to avoid situations where the weight of one infant is mistakenly stored as the weight of another infant, the device requires the user to select an individual number when there are multiple registered objects to be measured. Thus, the weight measuring device 12 of this embodiment is configured to operate in a way that is convenient for the user, according to the number of infants in the household.

[0062] Furthermore, the weight measuring device 12 of this embodiment may, for example, be initially set to have only one personal number that can be registered. In this case, the user may be able to set the number of personal numbers that can be registered. For example, if a user starts using the weight measuring device 12 of this embodiment around the time their first child is born, there is only one infant to be measured, and only one personal number to be used, thus reducing the effort required for the user to select one number from multiple registration numbers. Also, if a second child is born in the user's household and there are now two infants, the user can increase the number of personal numbers that can be registered.

[0063] In this embodiment of the weight measurement system 10, the transmission of measurement data from the weight measurement device 12 to the server 16 is performed using a measurement application installed on the terminal device 14. For example, by operating a data acquisition icon displayed on the screen of the measurement application, the user can read the measurement data stored in the weight measurement device 12 and transmit the measurement data to the server 16 via the terminal device 14.

[0064] The measurement app may also display a breast milk button and a formula button. The breast milk button is activated when the infant's weight is measured immediately after breastfeeding, and information indicating that breast milk was given is associated with this measurement result and sent to the server 16. The formula button is activated when the infant's weight is measured immediately after formula feeding, and information indicating that formula was given is associated with this measurement result and sent to the server 16.

[0065] Furthermore, if the weight measurement result from the weight measuring device 12 has not been transmitted to the server 16 for a predetermined number of days (for example, 5 days or more), the notification processing unit 36 ​​will notify the display 22 or the measurement application that the measurement result has not been transmitted to the server 16 for a predetermined number of days. In other words, the user needs to periodically transmit the measurement result to the server 16 each time they measure weight so that the server 16 can store it. This helps the user to get into the habit of recording weight on a daily basis. In this embodiment, if the measurement result has not been transmitted to the server 16 for a predetermined number of days or more, a process is performed to disable weight measurement by the weight measuring device 12 (hereinafter referred to as "measurement disablement process") along with the notification.

[0066] The measurement failure process is an example of notifying the user that the measurement result from the weight measuring device 12 has not been sent to the server 16 for a predetermined number of days or more. For example, if the measurement result from the weight measuring device 12 has not been sent to the server 16 for a predetermined number of days or more, the display 22 or the measurement application may display that the measurement result has not been sent to the server 16 for a predetermined number of days or more without performing the measurement failure process. Also, as an example of notifying the user that the measurement result has not been sent to the server 16 for a predetermined number of days or more, the user may be able to select whether or not the measurement failure process is executed through settings.

[0067] Figure 5 is a flowchart showing the flow of the milk feeding amount measurement process using the weight measuring device 12 of this embodiment. The milk feeding amount measurement process is a process of measuring the amount of milk fed by measuring the weight of the infant before and after feeding.

[0068] First, in step 300, the infant's weight is measured for the first time before breastfeeding, and the measurement result is displayed on the display 22 and stored in the memory unit 40.

[0069] In the next step 302, the infant's weight is measured for the second time after breastfeeding, and the measurement result is displayed on the display 22 and stored in the storage unit 40.

[0070] In the next step 304, the difference calculation unit 38 determines whether a predetermined button 24 for calculating the amount of milk fed has been pressed. If the determination is positive, the process proceeds to step 306; if the determination is negative, the calculation of the amount of milk fed is not performed and the process ends.

[0071] In step 306, the difference calculation unit 38 calculates the amount of milk fed, which is the difference between the second measurement result and the first measurement result. The calculated amount of milk fed may also be stored in the storage unit 40.

[0072] In the next step 308, the difference calculated in step 306 is displayed on the display 22 as the amount of milk fed. Each time the designated button 24 is pressed, the first measurement result, the second measurement result, and the amount of milk fed are displayed on the display 22 in a cycle.

[0073] Although the present invention has been described above using the embodiments described above, the technical scope of the present invention is not limited to the scope described in the embodiments above. Various modifications or improvements can be made to the embodiments above without departing from the spirit of the invention, and such modified or improved forms are also included in the technical scope of the present invention.

[0074] In the above embodiment, the subject of measurement was described as an infant, but the present invention is not limited thereto. The subject of measurement may be, for example, a small animal kept by the user. For example, the weight of the small animal may be measured and the measurement result stored by the same process as described above with respect to Figure 4 and steps 200 to 216, and the weight of the small animal may be checked over time using the measurement application described above. Also, for example, the intake of food, water, or medicine of the small animal may be calculated by the same process as described above with respect to Figure 5 and steps 300 to 308, and the intake amount may be stored in the storage unit 40.

[0075] In the above embodiment, a configuration in which the weight measuring device 12 is a baby scale was described, but the present invention is not limited thereto. The weight measuring device 12 may be a weight measuring device capable of measuring the weight of infants to adults, or it may be a body composition analyzer capable of measuring body composition in addition to weight.

[0076] In the above embodiment, a configuration was described in which the weight measuring device 12 transmits the measurement results to the server 16 via the terminal device 14, but the present invention is not limited thereto. For example, the weight measuring device 12 may be able to communicate with the server 16 via wireless communication such as Wi-Fi (registered trademark) without going through the terminal device 14, and transmit the measurement results to the server 16. In this configuration, the terminal device 14 is operated by the user to perform the registration process described with reference to Figure 3 and to confirm the measurement results stored in the server 16.
