The fast pace of life and irregular diet of modern people make it easy for many people to increase their weight, especially girls who don’t pay attention to them will get fat. Losing weight has become a major event for many people. If you want to do your job well, you must first sharpen your tools. If you want to lose weight, you must have a good partner: weight scales that can simply display weight are outdated, and smart body fat scales that can measure body fat are now the mainstream. The smart scale we developed can measure eight indicators of muscle content, water content, calories, weight, BMI, bone density, fat content, and visceral fat content, truly a scale that monitors daily body changes. And with the APP can help to record each measurement information, form a health database and generate health recommendations, remind the measurement regularly, and monitor body changes.

1. Introduction to the Smart Scale Solution

Smart scales can analyze our weight level. As we all know, different heights and different weights correspond to different weight classes. As long as the two aspects are combined, we can calculate our own obesity. However, ordinary people do not know how to combine the two and analyze the calculation. Get your own weight level. Then, with this smart scale, you can directly display your own weight level on the mobile phone APP software on your mobile phone, so that you can more clearly understand which level you are in. And then better strengthen the monitoring and management of one's own weight.

At the same time, the smart scale will make diet recommendations based on your weight level on the mobile app. The advantage is that we can clearly know what we can eat without a professional nutritionist, and eat Those things will be more beneficial to our own control of body weight. For example, if a relatively obese person eats something high in calories and fat, this will increase his own weight burden. And if when we know what to eat? We can avoid such situations through our own control, so as to better control our own weight and achieve a healthy physical condition.

Second, the advantages of smart scales

The emergence of smart scales allows consumers to better understand their own body mass index, and also allows consumers to manage their own indicators scientifically and rationally to achieve the goal of healthy exercise.

1. Stylish body. The smart scale has many functions, but this does not affect his beauty. The 15mm slim size of the body and the integrated matte bottom shell allow it to crush the smart scales of major brands in terms of appearance. It is simple, elegant and durable. The surface uses a hidden LED display to match the body, which is natural and beautiful.

2. High-end configuration. Compared with the 4-electrode configuration of other electronic scales, the smart scale uses 8-electrodes with heating function, which can measure human body weight, body fat, bone mass, BMI, muscle, water, basal metabolism, protein, etc. The 22 items of body data allow users to understand the physical condition of the whole body. The machine is equipped with a new generation of extremely low-power LED power management chips, and uses a 2000mAh lithium battery to meet the needs of use. It can stand by for a whole year after charging.

3. Easy to use. The smart scale is easy to use, and the function of linkage with the mobile phone allows the elderly at home to easily operate it. It has designed a family user account management function, which can be used by the whole family. An account can simultaneously manage the physical data information of 10 family members, and grasp the physical information of each family member in real time. Through the mobile phone APP, it can also provide users with professional advice on exercise and diet based on user information.

3. Introduction to the function of the smart scale

The weight scale seems to be a very common item, and now it has been played out. A new definition is given to it through the intelligent two characters. Of course, the smart weight scale is not only as simple as measuring a weight, it can also measure a number of data. In addition to measuring body fat percentage, smart scales can also be connected to mobile phones to automatically record daily measurement data. Some models can also share receipts on your sports bracelet to help you make better exercise plans.

The smart scale can also detect 8 human data: weight, water content, visceral fat content, muscle content, fat content, BMI overall health data, basal metabolism, and bone density content. Combined with the measured values, it analyzes the user's physical condition in detail and provides relevant health advice.

In addition, the cloud data of the smart scale is the core of the entire product. The APP supports automatic health recording of the personal health database, automatic recording of daily weighing data, and supports cloud storage without losing data even if the mobile phone is replaced.

Fourth, the development of smart scale APP

The smart scale APP can help users manage weight measurement standards and monitor their body weight in real time. However, the real-time weight bearing of the scale is displayed in real time, and the user can only see the current weight indicator. The development and customization of the smart scale APP can record the user's data on the scale and save it to form a weight data report. The data can be saved by connecting the device through Bluetooth.

1. The function of smart scale APP development

1) Health assessment: The shared weight scale APP performs a comprehensive assessment of the user's body composition and health status such as weight, fat, water, body age, bone mass, and muscle. The data is transmitted to the mobile phone via Bluetooth, and the user's physical condition and various items can be analyzed scientifically. Numerical level;

Five, the characteristics of smart scales

Smart scales are favored by users for their good reliability, accuracy, scale principle and technology, and simple structure. In business activities, smart scales are used more and more widely, bringing convenience to people's economic life.

1. The most basic function of the smart scale is to scale the weight. Three seconds after standing up, the smart scale can display the weight very accurately.

2. Turn on the alarm clock function, the smart scale can automatically remind you to weigh, and the alarm clock will automatically stop after the weight is completed.

3. The smart scale can quickly analyze your BMI (body mass index).

4. The smart scale can synchronize your weight and health information to a private health center by connecting to WiFi.

5. Stand barefoot on the smart scale. The smart scale can analyze the body fat ratio through your feet and automatically store the recorded information.

Sixth, the working principle of the smart scale

The working principle of the smart weight scale is to use a force sensor to deform the surface after placing a weight on the platform, which causes the shape change of the built-in resistor. The deformation of the resistor will inevitably cause the change of the resistance value, and the change of the resistance value. The change of the internal current produces a corresponding electrical signal, and the electrical signal becomes a visible number after processing.

1. Weight measurement

The principle of smart scales is similar to that of ordinary electronic scales, and they basically use pressure sensors. The shape of the smart scale has four contact points with the ground, and a pressure sensor is placed at the four contact points. The pressure sensor converts the weight of the human body into an electrical signal, which is sampled by the processor AD, and then converted to obtain The body weight.

2. Body fat measurement

The smart weight scale measures body fat by the electrical impedance method. The specific principle is that the electrode sheet emits a weak current to form a closed loop with the human body. Through the principle that muscles are easy to conduct electricity, fat does not conduct electricity, an electrical impedance value is obtained, and then The electrical impedance value is combined with data such as height and weight to calculate the body fat rate.

Seven, the meaning of the parameters of the smart scale

The parameters of the smart scale include body weight, body fat rate, muscle rate, bone mass, basic metabolic rate, water, body age, etc.

Weight: Body weight measured naked or wearing work clothes of known weight.

Body fat percentage: the proportion of body fat weight in the total body weight, and the percentage of body fat, which reflects the amount of body fat.

Muscle rate: The muscle rate is a ratio of the human body obtained by combining the total amount of human muscles, body weight, height, etc. The range of this value determines a person's physical health and strength.

Bone mass: The content of bone tissue [bone minerals (calcium, phosphorus, etc.) and bone matrix (collagen, protein, inorganic salts, etc.) per unit volume, used to represent the health of bones.

Basic metabolic rate: the energy metabolism rate of the human body in a state of being awake and extremely quiet, not affected by muscle activity, environmental temperature, food, and mental stress.

Moisture: It is the water content in the body, including blood, body fluids, etc.

Physical age: It is also commonly referred to as the biological age, which refers to the age in physiology. It is a brand new concept, representing the vitality of this person. The key to the physiological age depends on the person's lifestyle and health status.

Eight, the structure of the smart scale

The intelligent weight scale includes: load-bearing board, pressure sensor, main control board, liquid crystal display module board, and wireless communication module board. The connection between each component is a tight connection:

1. The pressure sensor is set under the load-bearing plate and collects the gravity signal applied on the load-bearing plate;

2. The main control board is arranged on the lower surface of the load-bearing board. The main control board includes: a single-chip microcomputer main control module, a data acquisition module, and a data acquisition module.

3. It has the corresponding ports connected with the pressure sensor and the main control module of the single-chip microcomputer;

4. The liquid crystal display module board is set on one side of the load-bearing board, and has a corresponding port connected with the main control module of the single-chip microcomputer;

5. The line communication module board is integrated and installed on the load-bearing board, and has a corresponding port connected with the main control module of the single-chip microcomputer.

IX. Precautions for the use of smart scales

1. The data error measured by the electrical impedance method used by the smart scale will be relatively large. The biggest culprit that affects the result of the body fat scale is the change of exercise and body moisture. Get different data.

2. Generally, the appropriate measurement time period is 1 hour after getting up, 1 hour before going to bed, and 1 hour after three meals. However, you can also measure according to your own habits. Note that each measurement is performed at the same time every day, and then pay attention to the above The essentials are fine.

3. It is best to use it in some relatively flat and hard places when weighing, and it is best to avoid relatively soft places, such as blankets, foam, etc., so as to ensure the accuracy of the data. Also, first confirm whether the four weighing feet are placed stably and whether they are suspended in the air.

4. You must stand firm when you are weighing. Standing in the middle of the scale, the left and right feet should be evenly distributed and in the middle of the scale, because this can make our data more accurate. If you are standing on the left or right side, this will cause some errors. Please pay attention.

5. In order to measure body fat mass, bone weight and other information more accurately, please go on the scale with bare feet.

6. When binding the mobile phone, make sure that the Bluetooth, wireless, and sports apps are turned on. If you stand on the scale, there is no response. May wish to unbind, remove the battery, stand on it again, and try connecting a new device.

7. Move the scale, if the display is still lit, keep the scale feet off the ground, and the first weighing reading after placing it stably will add about 2Kg, because the weight of the scale is automatically added to the reading. . After the indicator light goes out, stand up again, and the reading is normal. Therefore, the scale is generally placed in a corner or a fixed position. Don't move it around frequently. On the one hand, it will affect the accuracy. On the other hand, it will wear the floor.

10. Development prospects of smart scales

With the improvement of people’s living and cultural water level, smart technology is slowly becoming common in our daily lives, which makes many users think of moving electronic scale products to the intelligent route, which is convenient for users. Use, and can further improve the accuracy. In order to meet the needs of users, some manufacturers have conducted tests on different types of electronic scale products and launched the products to the market, which has also received a good response. At present, the outstanding functions of smart electronic scale products are touch screen operation, automatic weighing, automatic weighing data recording, weighing data export, upper and lower limit alarms can be set, optional external printers, statistical daily sales reports, etc. Features. With the advent of the intelligent age, the development of smart electronic scales is inevitable, and industry insiders have analyzed that the development prospects of the smart electronic scale industry are relatively optimistic.
