Abstract

PURPOSE:To automatically measure weight by automatically identifying a person to be measured who mounts a weight meter, classifying measured weight data every person to be measured, recording the data and outputting it. CONSTITUTION:When the person takes out his toothbrush from a toothbrush rack in a state where he mounts the weight meter 1, a corresponding toothbrush detection switch 4 is turned on and the detected weight data D0 is inputted in a microcomputer 2. Next, in the computer 2, the data D1 corresponding to the switch 4 is read out of the weight data stored in a RAM 23 and the data D1 and D0 are compared to decide whether or not a difference between them is smaller than a previously set reference value alpha. When the difference is smaller than the value, it is confirmed that the data D0 which has been just inputted belongs to the same person to whom the data D1 used for comparison belongs and the recording and the registration of the data are executed and the data is printed as individual data by a printer 3 if necessary.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an apparatus for automatically measuring the weight of a subject while identifying the subject.

<Conventional technology> In recent years, interest in health has increased, and weight, blood pressure,
More and more people are trying to measure and record their body temperature, etc. every day7, and use it as a barometer of their health, and ff1l+ devices that can be easily used at home are now commercially available.

<Problems to be solved by the invention> However, performing measurements and recording without fail is surprisingly troublesome and tends to become loose, and requires a strong will to obtain sufficient effects. To solve this problem, it would be desirable to have a device that allows measurement and recording to be carried out naturally in daily life, but such a device has not yet been developed.

The present invention has been made in view of these problems, and specifically aims to provide a device that allows a person to measure and record body weight naturally in daily life without being aware of it.

Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention provides a weighing scale disposed near a washstand and an identification means for automatically identifying a person to be measured who steps on the weighing scale. , a recording means for recording the measured body weight data for each subject, and an output means for outputting the recorded body weight data. In this case, it is desirable that the scale be placed in a position where the user naturally stands on the scale when washing or brushing teeth.

As the above-mentioned identification means, for example, a toothbrush detection switch may be provided in the toothbrush holder, and the person to be measured can be identified by opening and closing the switch when the toothbrush is taken out for use.

Furthermore, the above-mentioned identification can also be performed using body weight.

In this case, the measured weight data is compared with the recorded weight data, and the subject is identified from the recorded weight data with the smallest error.

〈Function〉 Just by stepping on a scale placed near the sink when washing or brushing your teeth, your weight will be automatically measured, identified, and recorded without you even being aware of it, and the results will be output to improve your health. Data useful for management can be obtained.

Furthermore, since the toothbrush is dedicated to each individual, the person to be measured can be reliably identified by using the toothbrush detection switch.

Furthermore, in a system in which the person to be measured is identified using weight data, there is no need for any operation by the person to be measured, and measurement and recording are performed fully automatically by simply stepping on the scale.

<Example> Next, the illustrated embodiment will be described.

FIG. 1 is a block diagram showing the configuration of an embodiment using a toothbrush detection switch, in which 1 is a weight scale, 2 is a microcomputer for control, 3 is a printer for output, and 4 is each compartment of a toothbrush holder. A plurality of toothbrush detection switches are installed in the toothbrush detection switch. Microcomputer 2 is
It is equipped with a CPU 21 that performs various calculations and controls, a ROM 22 that stores control programs, etc., a RAM 23 that stores measured weight data, an input boat 24, an output boat 25, etc., as shown in the flowchart of FIG. It operates according to the following steps.

That is, when a person takes out their own toothbrush from the toothbrush holder while standing on the scale 1, the corresponding toothbrush detection switch 4 is turned on, and the detected weight data D. is input to the microcomputer 2 (step Sl)
. In the next step S2, the microcomputer 2
From the weight data stored in the AM 23, data D corresponding to the detection switch 4 turned on is read out, and data D□ is obtained. It is determined whether the difference is smaller than a preset reference value α.

Note that the data D1 used for comparison at this time is registered as confirmation data through a process described later.

If the difference is small, data D is input. It is confirmed that the data belongs to the same person as the data D used for comparison, and the procedure proceeds to the next step 83 and subsequent steps to record and register the data.

This embodiment is an example in which the measurement period is divided into days, and in step S3, it is determined whether the data D used for comparison was input on the same day, and if it is not input on that day, step In S4, if the input is on the day, step S
Proceed to step 5 respectively.

In step S4, data D. is registered as a new data D to be used as confirmation data for the next comparison, and the original data D□ is incremented to D2, D2 to D□, and so on, and the data numbers are sequentially increased to Dr+-+Dn+t
Execute the processing.

In addition, in step S5, since the measurement data of the day has already become data D1 in the process in step s4 described above,
First, the current data D and the current input data D0 are compared with the data D2 used as confirmation data on the previous day. And data D. If the data D2 is closer to the data D2 and the difference is small, the current data D1 is deleted and the data D0 is newly registered as the confirmation data D.

The microcomputer 2 stores each piece of data Dn in correspondence with the date using a built-in calendar, and the above-mentioned processing records one piece of data Dn every day, and the latest data D8 is always used as confirmation data. become. Note that the above series of operations ends when the detection switch 4 is turned off, and the system returns to the initial standby state (step S6).

The above-mentioned processing is performed for all registered persons, so if necessary, the recorded data can be output using the printer 3 to output individual data in the form of a table or a transition graph. It will be obtained by

Figures 3 and 4 show an embodiment in which the subject is identified using body weight data. Figure 3 is a block diagram showing the configuration of the embodiment, and Figure 4 is a flowchart of the operating procedure. be. Hereinafter, points different from the above-mentioned embodiments will be explained.

In the figure, 1a is a scale switch built into the scale 1, and when a person steps on the scale 1, the scale switch 1a
is turned on, and the detected weight data D. is input to the microcomputer 2 (step 511). At this stage, unlike the previous embodiment, it is still unclear to whom the input data belongs. Therefore, the next step S2
In 1.

The microcomputer 2 reads the closest data D1 from among the weight data stored in the RAM 23, and takes the data D. It is determined whether the difference is smaller than a preset reference value α. and,
If it is small, it is data D that has been manually generated. It is determined that the data D2 and the data D2 used for comparison belong to the same person.

In the next step S4, data D. It is the same as in Fig. 2 in that the data number is registered as pig D and the data number is incremented to D n - + D n + 1, but in this example, data D is not for confirmation but for identification data. It differs from the previous example in one respect. Further, the processing in step S5 is also similar to that in FIG. 2.

When data D0 is newly registered, it is registered not as confirmation data but as identification data.

Through the above processing, one piece of data Dn is recorded every day,
Also, the latest data D1 is always used as identification data. The above series of operations ends when the weight scale switch 1a is turned off, and the scale returns to the initial standby state (step 561).

The above-mentioned processing is performed on the registered person's home, so if necessary, the recorded data can be output using the printer 3 to display individual data in tables or trend graphs. It will be obtained in the form of Furthermore, in this embodiment, there is no need to brush teeth, and the user only needs to step on the scale, which increases the number of opportunities for measurement, and is convenient because measurement and recording are performed fully automatically.

In addition to the toothbrush detection switch and weight data as in the embodiment, it is also possible to use height data or an image sensor to identify the person to be measured.

<Effects of the Invention> As is clear from the above-mentioned embodiments, according to the automatic weight measuring device of the present invention, the body weight is detected during the daily activity of washing the toilet, and the obtained weight data is identified by the identification means. Since the information is recorded for each person being measured, the measurement and recording can be performed without the person being particularly aware of it, and by outputting the results, useful data for health management can be obtained.

In addition, if the toothbrush detection switch is used to identify the J111, the identification can be performed reliably.

In addition, with the system that uses one weight data to identify the person being measured, there is no need for any operation by the person being measured, and the measurement and recording are fully automatic, so there is no need to forget the sub-settings, and it is convenient and easy to use. A body layer measuring device can be obtained.
