Specifically, the weight detecting device and the mobile terminal are wirelessly connected, and the user can select the heating mode of the weight detecting device on the mobile terminal, and control the heating of the weight detecting device by using the mobile terminal; wherein the weight detecting device includes a body fat scale, an electronic weight scale, and the like. The mobile terminal includes a mobile phone, an iPad, and the like. When the user selects the preset heating mode, the user can set the measurement time by himself or use the system default measurement time. The preset heating mode means that the heating zone of the weight detecting device has completed heating when the measuring time arrives.

As shown in FIG. 2 and FIG. 3, according to another embodiment of the present invention, a heating method of a weight detecting device includes the following steps: S10: acquiring a heating mode of a user selecting a body weight detecting device according to an operation instruction of a user; The heating mode includes using a heating mode, a preset heating mode, and an automatic heating mode;

S201. When the heating mode is to use the heating mode, obtain an ambient temperature value of an environment in which the weight detecting device is located;

S202. The heater on the weight detecting device heats the heated area on the weight detecting device according to the adjustable heating current according to the ambient temperature value and the preset target temperature value.

Preferably, the method further includes: S2021, calculating a temperature difference between the ambient temperature value and the preset target temperature value according to the ambient temperature value and a preset target temperature value;

S2022: Determine whether the temperature difference exceeds a preset temperature difference;

When the temperature difference does not exceed the preset temperature difference, step S2023 is performed; otherwise, step S2024 is performed;

S2023. The heating current of the heater is used to heat the heated area according to a first preset downflow speed;

S2024. The heater heats the heated area according to a heating current.

S2025, when the temperature difference exceeds the preset temperature difference, obtaining a heating temperature of the heated area according to a preset temperature sampling time (for example, sampling 10 times per second);

When the heated temperature reaches the preset heated temperature threshold, step S2027 is performed; otherwise, execution is performed. Step S2024;

S2027: The heating current of the heater is used to heat the heated area according to a second preset downflow speed.

Specifically, when the user selects to use the heating mode on the mobile terminal, when the user uses the weight detecting device, the function of opening the weight detecting device needs to be turned on on the mobile phone. At this time, the heater on the weight detecting device needs to quickly heat the heated area to ensure the user's experience. In order to ensure the user's experience, that is, when the user stands on the weight detecting device, the temperature of the upper surface of the weight detecting device should be close to the temperature of the user's foot, and at the same time, the user cannot be burned, and the current environment of the weight detecting device is combined with Ambient temperature values, using different heating methods.

When the ambient temperature value (for example, 20 ° C) is relatively high, and the preset target temperature value (for example, 28 ° C) is not much different, the heater uses the heating current (for example, 10 A) to heat the heated region, due to 10A. Use a large heating current for 10A. Heating with a heating current will burn the user. Thus, 10A heats the upper surface layer of the body weight detecting device after the current is lowered at the first predetermined downflow speed (2 A/per second) using the heating current.

When the ambient temperature value (for example, 2 ° C) is relatively low, and the difference from the preset target temperature value (for example, 28 ° C) is large, the heater continues to use the heating current to heat the upper surface layer of the weight detecting device for a period of time using 10 A. The upper surface layer of the weight detecting device is heated faster. Since the 10A uses a large heating current, it has been heated by the heating current of 10A, which will burn the user. Therefore, the temperature of the surface layer on the weight detecting device is collected 10 times per second, and it is determined whether or not the heating current is reduced by 10 A based on the temperature of the surface layer of the body weight detecting device. For example, when the heating temperature of the upper surface layer of the weight detecting device (for example, 12 ° C) does not reach the preset heating temperature threshold (for example, 22 ° C), the heater continuously uses 10 A to heat the surface layer of the weight detecting device by using the heating current. . When the heated temperature of the upper surface layer of the weight detecting device (for example, 23 ° C) reaches the preset heating temperature threshold (for example, 22 ° C), the heater continues to use the heating current of 10 A according to the second preset downflow speed (5 A/ After the downflow per second, the surface layer of the body weight detecting device is heated.

As shown in FIG. 3 and FIG. 4, according to still another embodiment of the present invention, a heating method of a weight detecting device includes the following steps: S10: acquiring a heating mode of a user selecting a body weight detecting device according to an operation instruction of a user; The heating mode includes using a heating mode, a preset heating mode, and an automatic heating mode;

S202. Add the weight on the weight detecting device according to the ambient temperature value and a preset target temperature value. The heater heats the heated zone on the weight detecting device in a manner that is adjustable in heating current.

S2024. The heater heats the heated area according to a heating current.

S2025, when the temperature difference exceeds the preset temperature difference, obtaining a heating temperature of the heated area according to a preset temperature sampling time;

When the heated temperature reaches the preset heated temperature threshold, step S2027 is performed; otherwise, step S2024 is performed;

S211, when the heating mode is the preset heating mode, determining whether the current time reaches the preset heating time; the preset heating time is earlier than the preset measurement time in the preset heating mode;

When the current time reaches the preset heating time, step S212 is performed; otherwise, step S211 is performed;

S212. The heater on the weight detecting device heats the heated area on the weight detecting device according to a preset heating current constant manner during the preset heating time to the preset measuring time.

Specifically, when the user selects the preset heating mode on the mobile terminal, the user can set the preset measurement time (for example, Monday to Friday 20:00), or use the default preset measurement time (for example: Monday to Sunday 9:00). The preset heating time can be 3 minutes before the measurement time (19:57 Monday to Friday or 8:57 Monday to Sunday), 5 minutes (Monday to Friday 19:55 or Monday to Sunday 8:55) Wait. When the current time reaches the preset heating time (19:57 or 8:57), the weight detecting device is controlled by a constant heating current (for example, 4.5A) from 19:57 to 20:00 or 8:57 to 9:00. The upper surface layer is heated.

As shown in FIG. 3 and FIG. 5, according to still another embodiment of the present invention, a heating method of a weight detecting device, The method includes the following steps: S10. Acquire a heating mode of the user selecting the weight detecting device according to an operation instruction of the user; the heating mode includes using a heating mode, a preset heating mode, and an automatic heating mode;

S2024. The heater heats the heated area according to a heating current.

S203. When the heating mode is the heating mode, the measurement time when the user uses the weight detecting device is statistically recorded, and the usage rule of the user using the weight detecting device is obtained.

S221. When the heating mode is the automatic heating mode, the heater on the weight detecting device automatically heats the heating zone on the weight detecting device according to the usage rule and the automatic heating current constant mode. The automatic heating current may be equal to the preset heating current, or may be slightly larger or slightly smaller than the preset heating current, for example, greater than or less than the preset heating current 1A.

Specifically, when the user selects the automatic heating mode on the mobile terminal, when the user does not use the weight detecting device, the weight detecting device can follow the system default heating time in a constant heating current (for example, 4.5A). The upper surface layer of the body weight detecting device is automatically heated. When the user uses the weight detecting device multiple times in the heating mode, the user analyzes the usage time of the user using the weight detecting device to obtain a usage rule; for example, the user often uses the weight detecting device at around 15:00. The weight detecting device automatically heats the heated area at 15:00 with a constant heating current of 4.5A.

The heating control module 15 is further configured to: when the current time reaches the preset heating time, control heating on the weight detecting device during the preset heating time to the preset measurement time The heated area on the weight detecting device is heated in a constant heating current manner.

The heating control module 15 is further configured to: when the heating mode is the automatic heating mode, control the heater on the weight detecting device to detect the weight according to the usage rule and the automatic heating current constant mode. The heated area on the device is automatically heated.

Specifically, the heater includes a plurality of electric resistance wires uniformly disposed in the weight detecting device, and a circuit board is disposed on a lower side of the plurality of electric resistance wires, and a first insulating layer is disposed between the circuit board and the plurality of electric resistance wires. The temperature acquisition module 12 includes a temperature sensor disposed on an upper side of the heater, and a second insulation layer is disposed between the temperature sensor and the plurality of resistance wires. A resistor wire heats a small area. Similarly, the temperature sensor is also measured in blocks. In addition to this, the upper surface of the weight detecting device is provided with an electrode sheet or the like which is electrically connected to the control chip on the circuit board.

As shown in FIG. 7, FIG. 8, and FIG. 9, according to an embodiment of the present invention, a heating method of a weight detecting device includes the following steps: a user measures according to a time set by himself, and then the weight detecting device can be set according to Preheating and heating at a fixed time. The temperature sensor obtains the current temperature, compares it with the optimum temperature of the human sole, adds the time variable, and adds the resistance variable of the resistance wire for heating, which can be heated three minutes in advance or five minutes in advance. The temperature requirement is met when the specified time point is reached.

The user does not measure according to the fixed time point. Since the user will open the application before measuring the body fat, the application will send a heating command to the weight detecting device. At this time, the weight detecting device performs automatic heating. Because the time is short, the heating power will be very high. Large, at this time, the temperature sensor layer needs to feedback the temperature change in time, and the processor adjusts the current according to the temperature change condition in time, so that the user can reach the requirement when the scale is reached in a short time without being too high, and a good use experience is obtained.

The specific situation can set the time, temperature, current three variables, set the sensor to collect 10 times per second temperature, Then, the two adjacent temperature differences *10 are the temperature change amounts, and the difference between the current temperature and the set temperature and the temperature change amount is the heating time. There is a certain mathematical relationship between the heating time, the temperature change rate and the current of the heating resistor wire. When the heating time is relatively long, the temperature change speed is inversely proportional to the current to prevent the heating from being too fast. When the required heating time is shorter, there is no need to consider the temperature change, the current is gradually reduced, and so on.

When other factors are not considered, the heating curve should be S1 line, but when the integrated user wants to scale, the time is relatively short, so the early heating needs to be faster, the later heating should be slower to prevent excessive heating, so the S2 line will be selected. The curve of the heating goes.

The S2 area on the left side of the dotted line is when the current temperature and the set temperature are greatly different. At this time, the processor can directly perform rapid heating without considering the current temperature factor. When the temperature curve enters the S3 area on the right side of the dotted line, Taking into account temperature variations, the processor can gradually reduce the heating current to prevent overheating.

Specifically, in the hardware design, considering that if one wire is used, if the fault occurs, the user experience of heating cannot be guaranteed, and other heat factors of different parts of the weight detecting device have other uncertain factors, so multiple The mode in which the resistance wires work separately through the power management module. A resistor wire heats a small area, and the same temperature sensor is also measured in blocks. When the value measured by a certain temperature sensor deviates greatly from the value measured by other sensors, the current of the resistance wire corresponding to the sensor can be appropriately adjusted by the processor to perform intelligent temperature control.

The overall structure of the surface of the scale is the uppermost layer is a conductive layer. In order to measure the body fat, the second layer is a temperature sensor layer, which can measure the temperature of the surface of the entire body weight detecting device, and the third layer is a resistance wire layer for the entire scale. The surface is heated.

If the resistance wire is at the top, the value measured by the temperature sensor may be biased, resulting in excessive heating. It must be ensured that the temperature sensor measures the same temperature as the human foot, so the temperature sensor is set in the resistance wire and the most There should be insulating glass isolation between the layers of the upper layer.

When the user sets the time of the scale, the weight detecting device will preheat according to this time and the current temperature to ensure the user experience. In addition, the weight detecting device records the time when the user performs the measurement into the database, and adds factors such as the date and time, for example, the user does not need to consider the measurement problem at night, and the working day does not consider the user measurement problem during the day. Perform unified calculation predictions and perform intelligent heating during the predicted time period.

Considering that the product is intelligent hardware, it communicates with the mobile device. When the user connects the weight detecting device with the mobile terminal device, the user can be considered to perform body fat weight measurement, and the weight detecting device starts heating. In addition, health monitoring functions can be added to the user terminal application for daily or weekly When the measurement is made, the weight detecting device can be given a timed command to enable it to be heated for a fixed period of time.

It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It should be considered as the scope of protection of the present invention.
