Description

Weight detecting device and heating method thereof

Technical field

The invention relates to the technical field of intelligent heating body fat scales, in particular to a body weight detecting device and a heating method thereof.

Background technique

At present, the quality of life of the people in the country is constantly improving, and everyone is pursuing higher and higher quality of life. Due to the rising standard of living, everyone's weight has risen very quickly. In order to maintain a good body, everyone pays close attention to their weight. The electronic weight scale is easy to measure and measure weight, and the human-computer interaction is good. It is welcomed by the public and its market is expanding.

A healthy body lies in the balance of fat in the body. Excessive accumulation of fat is harmful to the body and causes various diseases. Human body fat is an important part of the human body and has important functions and functions in the human body, such as providing energy, protecting internal organs, maintaining body temperature, assisting in the absorption of water-soluble vitamins, and participating in human metabolic activities. However, too much fat can affect human health, diabetes, and cardiovascular and cerebrovascular diseases.

Existing weight scales not only measure the body weight but also the body's fat content. The body fat scale uses the electrodes on the surface of the scale body to contact the legs of the user, and measures the body resistance through a certain safe current. Based on the input user data and the measured body resistance, it is able to accurately measure the percentage of body fat, body moisture percentage, body muscle percentage, and bone weight. However, the current body fat scale requires the user to stand on the surface of the scale containing the electrode to measure the impedance. The surface of the scale is generally made of glass, and the electrode is made of metal. When the indoor temperature is low in winter, the dial of the body fat scale is relatively cold. At this point the foot is in direct contact with the surface of the cold scale. In the winter, the feet are frozen, and the feet are frostbitten, causing the user to catch a cold.

Application Publication No. CN 104068856 A, the invention patent application filed on October 1, 2014, discloses a body fat scale having a surface heating function and a method of using the same, including: opening a heating function and a preset heating function, The body of the body fat scale is provided with a heating area, and the body of the body fat scale is heated before use by the user. When used, the user bare feet stand on the body fat scale and feel comfortable.

The body fat scale in the patent can only heat the body of the body fat scale in a single heating mode, so that the scale The temperature of the body reaches a preset heating temperature. Single heating mode In different temperature and humidity environments, the heating time required to reach the preset heating temperature is different. Even with the preset heating function, it is difficult for the user to set the preheating time point based on the indeterminate heating time, so that the body fat scale can completely match the user's usage rhythm. If the preset time is too early, it will inevitably increase the resources such as electric energy required for heating, and the long-time heating will also affect the material life of the scale surface, and the life of the sensor installed in the scale body will also be affected. The preset time is too late. When the user needs to use, the temperature of the surface of the body fat scale does not reach the preset heating temperature, or the user needs to wait for a period of time to reach the preset heating temperature, and the user experience is greatly reduced.

Measuring zone temperature sensor 24. Wherein, the ambient temperature sensor 23 is disposed at the bottom edge of the body fat scale to reduce the body fat scale heating affecting the ambient temperature sensor 23 to interfere with the measurement of the ambient temperature. Two measuring zone temperature sensors (24a, 24b) are arranged in the measuring function zone, respectively arranged in the lower part of the active foot area when the corresponding human body stands on the surface of the scale, and are used for detecting the temperature after the corresponding positions of the two legs of the body fat scale are heated. The measurement zone temperature sensors (24a, 24b) are surface-mount temperature sensors attached to the sides of the two measurement electrodes 22 shown in FIG.

The heating unit 31 and the power driving unit 32 are included, and the power driving unit 32 outputs power to the heating unit 31 to drive the heating unit 31 to generate heat to heat the surface of the scale. The heating unit 31 is arranged on the surface of the scale corresponding to the foot of the human body (ie, the measuring function area), and the metal is wrapped with a large resistance wire to ensure uniform heating.

The control module 4 is electrically coupled to the mass sensor 21, the measurement electrode 22, the ambient temperature sensor 23, and the measurement zone temperature sensor 24 to receive detection data from the sensing elements of the sensing module. At the same time, the control module 4 is also electrically connected to the power driving unit 32, and the control module determines the working mode of the heating module according to the environmental parameter value input by the sensing module. Based on the determined mode of operation, a corresponding control signal is output to the power drive unit 32 to control the output power of the power drive unit 32.

Wherein, in the starting step S1, the ambient temperature is used as an input variable, and the heating mode is determined in combination with the ambient humidity.

Under normal circumstances, the higher the humidity at the same temperature, the lower the temperature perceived by the human body. Generally, the suitable humidity of the human body is in the range of 45% to 65%, and the humidity is defined as 0 level; the humidity range is 65%-75%, the definition level is 1 level; the humidity range is 75%-85%, which is defined as level 2; The humidity range is 85%-100%, which is defined as level 3.

The seasonal factor refers to the information of the current season, where the summer is 0, the fall and spring are defined as level 1, and the winter is defined as level 2. The total heating level is also calculated by a weighted average, where the weight of the season is the smallest. For example, the weight of the temperature is 0.85; the weight of the humidity is 0.1, and the weight of the season is 0.05. The formula for calculating the total heating level is:

Hotsum=temp*k1+hum*k2+sea*k3;

K2 is the humidity weight,

K3 is the seasonal weight,

Temp is the temperature level,
