Description

A weighing scale capable of displaying weight change curves

technical field

The invention relates to a household weight scale, which belongs to the field of electronic technology.

Background technique

At present, weight has become a health indicator that people are very concerned about, especially young women, who regard weight control and beauty as equally important. As a result, weighing scales have entered thousands of households. However, the current electronic weighing scales do not have the function of data recording, and there is no function of displaying weight change curves and querying past weight data.

Contents of the invention

The purpose of the present invention is to provide a weight scale that can transmit the measured weight data to the home computer through the wireless data transmission module and record it in the database, and can query the weight data of the past at any time and display the weight change curve and the warning information of excessive weight .

In order to achieve the above purpose, the following technical solutions are adopted:

The invention includes a pressure sensor for measuring body weight, a single-chip microcomputer a, a liquid crystal display, a wireless transceiver module a, and a PC, a single-chip microcomputer b, and a wireless transceiver module b for displaying, inquiring and printing weight information. It is characterized in that: the pressure sensor is connected with the single-chip computer a, the single-chip computer a is connected with the liquid crystal display and the wireless transceiver module a; the PC is connected with the single-chip computer b through the serial port, and the single-chip computer b is connected with the wireless transceiver module b.

Build a weight database and information management system with VB on the PC to display current weight data and past weight change curves, and also query previous weight measurement values. When a certain measured weight exceeds the standard, a prompt window will be displayed information.

Operating procedure and work process of the present invention are:

First turn on the computer, then run the weight information management system, and then log in. When the user name and password entered are correct, click the "Measurement" button on the information management system, and then stand on the weighing scale. When the data on the LCD display is stable Finally, the data is transmitted to the PC through two wireless transceiver modules, and the weight information management system running on the PC displays the weight data just measured, and automatically recalls the previous weight data to form a weight change curve. If you want to query earlier weight data or print the weight data report within a certain period of time, you can click the "Query" button or "Print" button on the information management system to achieve.

The positive effects of the present invention are: 1. The weight data measured each time can be stored in the database; 2. The weight data within any period of time can be queried and printed; 3. The weight change curve within a period of time can be automatically formed; 4. An early warning message can be sent to those who are overweight. It helps people realize their desire for health and beauty.

Fig. 1 is a functional block diagram of an embodiment of the present invention.

Detailed ways

The technical content of the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

As shown in Figure 1, a kind of weighing scale that can display body weight change curve, comprises and pressure sensor 1, single-chip microcomputer 2, liquid crystal display 3, wireless transceiver module 4, PC 5, single-chip microcomputer 6, wireless transceiver module 7 and antenna 8. It is characterized in that: the pressure sensor 1 is connected with the single chip 2, the single chip 2 is connected with the liquid crystal display 3 and the wireless transceiver module 4; the PC 5 is connected with the single chip 6 through the serial port, and the single chip 6 is connected with the wireless transceiver module 7.

In Fig. 1, the pressure sensor 1 chooses the electronic human body scale sensor, the single-chip microcomputer 2 and the single-chip microcomputer 6 choose STC11F01 packaged in SOC16 package of domestic single-chip microcomputer with low price and small size, the liquid crystal display 3 adopts a 4-bit segment liquid crystal module, and the wireless transceiver module 4 and 7 adopts PTR8000, the module has its own antenna, which can be directly connected with the single-chip microcomputer, and the PC 5 can use the existing desktop or notebook computer in the family.

It must be pointed out that the above example is only a non-limitative illustration of the invention. However, those skilled in the art will understand that without departing from the spirit and scope of the present invention, various modifications, replacements and changes can be made to the present invention, and these modifications, replacements and changes still belong to the protection scope of the present invention.
