When the mobile phone 200 is mounted, the scale 100 and the mobile phone 200 are connected to each other through a 24-pin standard connector (consisting of a socket installed on the mobile phone and a plug installed on the scale) (S1).

When the scale 100 and the mobile phone 200 are connected, the scale 100 receives power from the battery of the mobile phone, performs an initialization operation, and communicates with the mobile phone 200 through a 24-pin standard connector to transmit the scale ID. (S2, S3). Accordingly, the mobile phone 200 recognizes that the scale 100 is connected and drives an application related to weight measurement (S4).

Subsequently, the weight scale 100 performs calibration for accurate weight measurement, and when the measurement preparation is completed, communicates with the mobile phone 200 through the 24-pin standard connector and reports the measurement preparation completion (S5, S6). Accordingly, the mobile phone 200 displays the text requesting weight measurement on the LCD screen of the mobile phone 100 and outputs the voice through the speaker in a TTS (Text To Speech) method (S7).

Subsequently, when the user measures the weight, the microprocessor 124 of the scale may report to the mobile phone 200 that the weight is being measured, thereby guiding that the mobile phone 200 is measuring the weight (S8 to S10).

When the weight measurement is completed, the weight scale 100 transmits the measured weight value to the mobile phone 200 through the 24-pin standard connector. Accordingly, the mobile phone 200 stores the received weight value in a memory and then displays it on the LCD screen. In addition to the display in the voice output through the speaker (S11 ~ S13).

On the other hand, the mobile phone 200 used in the present invention may provide various functions by driving a weight measurement-related application program, as shown in Figure 7 may provide a corresponding function through the menu of the mobile phone 200. . Referring to FIG. 7, the menu that can be provided to the mobile phone 200 in relation to the present invention is "1.Weight measurement" 701 as a sub menu in the basic menu item "1.1 New measurement" 711, "1.2. Items such as "measurement value display" 712, "1.3 measurement data upload" 713, "1.4 mobile service" 714, and the like.

According to this menu method, the user may select the "weight measurement" 701 menu in the state in which the scale 100 is connected, and then click the "new measurement" 711 to newly or re-measure the weight.

In the state in which the scale 100 is not connected, the user selects the “weight measurement” 701 menu of the mobile phone 200 and then clicks the “display measurement value” item 712 to weigh previously measured and stored in the memory. Value and weight-related indicator values (BMI, etc.) can be checked, and the measured weight data can be uploaded to the server of the mobile service by clicking the "upload measurement data" (713) item, and the "mobile service" (714) item. You can also access a mobile service through a variety of services.
