1-3 illustrate a semiconductor intelligent health scale, according to embodiments of the present disclosure, comprising: a scale body 10; a controller 200 disposed within the scale body 10; the weighing module 301 is arranged in the scale body 10 and used for sensing the pressure applied to the upper surface of the scale body 10 and converting the pressure into a first electric signal, and the weighing module 301 is electrically connected with the controller 200 through a first electric signal input end of the controller 200 so as to send the first electric signal to the controller 200, thereby realizing the measurement of the weight; and an electrode 11, wherein the electrode 11 is arranged on the upper surface of the scale body 10 and is electrically connected with the controller 200 through a second electric signal input end of the controller 200 so as to measure the biological resistance information of the human body when the human body is positioned on the upper surface of the scale body 10; wherein the controller 200 is configured to include a body fat mode and a nutrition mode, wherein: under the body fat mode, the semiconductor intelligent health scale measures the biological resistance information, and therefore body fat information of a human body is obtained; or in the nutrition mode, the semiconductor intelligent health scale performs measurement of the weight of the food 13 contained by the tray 12 so as to derive the nutrient content of the food 13 in combination with the kind of the food 13; and the controller 200 is further configured to provide a recommended intake weight of the food 13 based on the derived body fat information of the human body, the kind of the food 13, and the nutrient content of the food 13.
In this embodiment, the weighing module 301 may include a sensor, such as a piezoelectric material or a piezoresistive material. In the case of piezoresistive materials, when the piezoresistive material is deformed by pressure, the resistance of the piezoresistive material changes, and then a voltage is applied to the piezoresistive material, so that a value of the pressure can be obtained by measuring the resistance of the piezoresistive material. In the case of piezoelectric materials, the piezoelectric materials generate current or voltage signals under the action of pressure, and the value of the measurement signals can obtain the value of the pressure, namely the weight of the human body on the scale body. The weighing module 301 may also be configured in other principles. In this embodiment, the first electrical signal is a signal corresponding to the weight, may be an electrical signal representing a resistance value, may be an electrical signal representing a voltage value, may be an analog signal, and may also be a digital signal. The weighing module 301 may include circuitry or other components, the weighing module 301 may include only piezoresistive or piezoelectric materials, etc., and the circuitry portion may be included in the controller 200.
In this embodiment, the semiconductor intelligent health scale may include two weighing modules. For example, one weighing module is used for weighing a person's body weight and the other weighing module is used for weighing food 13.
In this embodiment, the controller 200 may be a semiconductor circuit, which is advantageous in that the semiconductor circuit has the advantages of low power consumption, fast response, high integration, small size, and low cost.
In this embodiment, the method of measuring body fat of a human body is similar to the existing method of measuring body fat, that is, the fat content of a human body is measured using a bioelectrical impedance measurement method. The human body stands on the electrode 11 on the scale body 10 with bare feet, weak current passes through the electrode 11, and the muscle content can be known according to the rule that fat in the body is not conductive and water in the body is conductive, so that the proportion of fat in the body weight can be judged according to the difficulty of passing current. The prior art body fat scale can provide the fat content information of the human body, however, it is inconvenient to additionally use the scale to weigh the food 13. Generally, it is contemplated that additional scales may be used to weigh the food items 13 to avoid the food items 13 from being soiled, since it is contemplated that body fat scales may require bare feet to stand on the scale. In an embodiment, the intelligent health scale comprises a body fat mode and a nutrition mode, so that the purposes of weighing the human body and measuring the body fat and the purposes of weighing the food 13 can be provided at the same time, and therefore the recommended intake weight of the food 13 can be provided according to the body fat information of the human body and the nutrition element content of the food 13, and more health information can be provided compared with the existing body fat scale, and the intelligent health scale is convenient for a user to use.
In this embodiment, the controller 200 may have a storage function, for example, may include a memory, not shown in fig. 3, but it should be understood that it may be a part of the controller's circuit, which may store the historical weight of the human body, the body fat information, the plurality of foods 13 consumed, the usage amount of each food 13, and the like, and automatically save the correspondence of these information with time, thereby providing a more scientific recommended intake weight of a certain food 13 according to the combination of the historical health information of the human body and the weight of the food 13. It should be noted here that, because the body fat measurement and the weighing analysis of the food 13 are combined, the intelligent health scale automatically stores the information of the weight, the body fat and the food 13 eating amount in a certain day, which is beneficial to analyzing the relationship between the food 13 intake and the body fat, and the user experience is more convenient to use. For example, when the number of days in which the user has eaten lean meat more than 300 grams or the number of days in which the user has eaten lean meat more than 300 grams in the past month exceeds a certain number, the user has an increase in weight, which may be related to other aspects such as the user's exercise, and the intelligent health scale recommends a decrease in the amount of lean meat eaten based on this information, which is not possible with the existing body fat scales.
In this embodiment, the use of the tray 12 prevents the food 13 from contacting the scale body 10 that has been in contact with the human body, and keeps the food 13 sanitary.
In the embodiments of the present disclosure, although the expression of the first electrical signal input terminal of the controller 200 is used, it should be understood that the controller 200 and the weighing module 301 may be electrically connected through a circuit, the first electrical signal input terminal may be a part of the circuit at this time, and the first electrical signal input terminal is used for convenience of the expression, and it is not necessary to separate the weighing module 301 and the controller 200 and electrically connect through a separate terminal. The controller 200 may be electrically connected to the electrode 11 by a circuit, without having to provide a separate second electrical signal input of the controller 200, or the second electrical signal input may be considered to be part of the circuit or a line.
The controller 200 is further configured to store the weight of the tray 12, and subtract the measured weight of the food 13 held by the tray 12 from the inherent weight of the tray 12 to derive the weight of the food 13. Such an arrangement facilitates a user to directly obtain the weight of the food items 13 without requiring the user to weigh the tray 12 separately and then use the weight of the food items 13 held by the tray 12 minus the weighed weight of the tray 12 to derive the weight of the food items 13. However, the intelligent health scale may be set so as not to automatically subtract the weight of the tray 12, e.g., the user may place food 13 contained in another receptacle (e.g., a bowl) on the scale body 10 for weighing the food 13.
In one embodiment, the controller 200 is configured to further include a sleep mode. Under the condition that the scale body 10 is empty, when the semiconductor intelligent health scale is in a sleep mode, the controller 200 starts the weighing module 301 at a first time interval, and detects whether an electric signal at a first electric signal input end changes; and/or the controller 200 applies a rest pulse voltage to the electrode 11 at a second time interval and detects whether there is a change in the electrical signal at the second electrical signal input terminal.
In this embodiment, the controller 200 may activate the weighing module 301 for example once every second, for example, once every second (or two seconds, which may not affect the user experience), provide the sleep pulse voltage to the weighing module 301 for example once every second (i.e., only provide the sleep pulse voltage to the weighing module 301 once in one second), if (for example) the resistance of the piezoresistive material in the weighing module 301 does not change, the electrical signal at the first electrical signal input terminal does not change, and the controller 200 defaults that there is no human body or food on the intelligent health scale, and then the intelligent health scale continues to maintain the sleep state. By doing so, the controller 200 does not always provide voltage to the weighing module 301, and the cumulative time of providing voltage over the course of a day may be less than ten minutes, thus saving significant power, which may be particularly advantageous for health scales using, for example, dry or rechargeable batteries, which may extend endurance.
In this embodiment, the first time interval and the second time interval may be the same or different, for example, the first time interval is 1 second, and the second time interval is 1.5 seconds, which does not need to be determined. The first time interval and the second time interval may or may not be synchronous. The first time interval and the second time interval are not synchronous, that is, the controller 200 may provide the sleep pulse voltage signal to the weighing module 301 and the electrode 11 in a time-sharing manner, so that the user waiting time may be shortened, and the user experience may be improved.
In this embodiment, the sleep pulse voltage provided to the weighing module 301 may be the same as or different from the sleep pulse voltage applied to the electrodes 11. The value of the rest pulse voltage may be different from the voltage value used for actual weighing or the voltage value used for body fat measurement. The voltage value used for actual weighing or the voltage signal used for body fat measurement may be a continuous signal or a pulse signal.
In one embodiment, the controller 200 is configured to further include a first wake-up mode, such that when the tray 12 is placed on the scale body 10 or a human body stands on the scale body 10, the controller 200 detects a change in the first electrical signal input when the weighing module 301 is activated, and the semiconductor intelligent health scale wakes up to start weighing and/or start measuring human body resistance. In this embodiment, the controller 200 may provide the sleep pulse voltage to the weighing module 301, when the piezoresistive material in the weighing module 301 is deformed under pressure and the resistance changes, the controller 200 detects the change of the electrical signal at the first electrical signal input end, i.e. the change relative to the predetermined value, so that the controller 200 determines that a heavy object has been placed on the scale body 10, and thus wakes up the semiconductor intelligent health scale to start weighing and/or start measuring the human body resistance. For example, the controller 200 may provide a weighing voltage to the weighing module 301 at this time, and measure the weight of the human body or the tray 12 on the scale body 10 by receiving an electrical signal generated by the weighing module 301.
In this embodiment, the user is allowed to use other receptacles without having to wake up the smart health scale using the fixed tray 12.
In embodiments of the present disclosure, the intelligent health scale may include buttons 15 disposed on the scale body 10, such as the buttons 15 disposed on the upper surface of the scale body 10 as shown in fig. 1. The keys 15 can also be arranged on other surfaces of the scale body 10. For example, a start button may be disposed on the upper surface of the scale body 10, and a user may wake up the intelligent health scale by pressing the start button; other keys, such as a body fat measuring key, a nutrition key and the like, can be arranged on the scale body 10; however, it is conceivable that, in the embodiment of the present disclosure, the key may be unnecessary, which may avoid cost increase due to the use of the key, maintenance trouble due to damage of the key, and life limitation.
In one embodiment, the controller 200 is configured to further include a second wake-up mode, such that when the tray 12 is placed on the electrode 11 on the scale body 10, the electrode 11 is turned on, the controller 200 detects a change in the electrical signal at the second electrical signal input, the semiconductor intelligent health scale is woken up and switched to the nutrition mode to start measuring the weight of the food. In this embodiment, the outer surface of the tray 12 is electrically conductive, so that the electrodes 11 can be switched on when the tray 12 is placed on the electrodes 11 on the upper surface of the scale body 10. The tray 12 may be, for example, a tray 12 formed of plastic or ceramic material, and the surface of the tray 12 is coated with a conductive film, which may be, for example, a metal conductive film. In another embodiment of the present disclosure, the tray 12 may be a tray 12 formed of an electrically conductive material, such as a metal tray 12. In this embodiment, when the tray 12 is turned on the electrode 11, the sleep pulse voltage applied to the electrode 11 by the controller 200 causes a current signal, and the controller 200 detects the electrical signal at the second electrical signal input terminal, and switches the intelligent health scale from the sleep mode to the nutrition mode.
In this embodiment, since the second wake-up mode is provided, when the first time interval and the second time interval are not synchronous, the first wake-up mode and the second wake-up mode can work in turn, which makes wake-up more timely and optimizes user experience. For example, the first time interval is two seconds, the second time interval is two seconds, and when the first time interval and the second time interval are staggered, even if the sleep pulse voltage signal for weighing in the first wake-up mode is missed, the sleep pulse voltage signal applied to the electrode 11 can still be caught up, so that the intelligent health scale can be woken up in one second through the electrode 11.
In one embodiment, the controller 200 may include a hall circuit 201, the tray 12 is magnetic, and the controller 200 is configured to include a third wake-up mode such that when the tray 12 is placed on the scale body 10, the hall circuit 201 senses the magnetic tray 12, thereby waking up the semiconductor intelligent health scale and being switched to the nutrition mode. It may be advantageous to provide a third wake-up mode, which may provide a redundant design for the intelligent health scale. For example, a smart health scale may be awakened when a receptacle (not necessarily required to be the tray 12) formed of a magnetic material is placed on the scale body 10. In another embodiment, the hall circuit 201 may be a separate circuit from the controller 200.
In one embodiment, the controller 200 may include a calibration circuit 202 configured to calibrate the first electrical signal input from the first electrical signal input after the semiconductor intelligent health scale is woken up, convert the first electrical signal into a digital signal and compare the digital signal with data stored in the controller 200, thereby obtaining the weight of the human body or the weight of the tray 12 containing the food 13; also, the calibration circuit 202 does not calibrate the electrical signal at the first electrical signal input terminal while in the sleep mode. Here, the data stored in the controller 200 may be comparison data of the value of the electric signal and the weight, which may be stored in the controller 200 or in a memory in the controller 200 by a preset setting. In other embodiments of the present disclosure, after being awakened, the semiconductor intelligent health scale may be directly switched to, for example, a body fat mode, and then the calibration circuit 202 calibrates the first electrical signal input by the first electrical signal input terminal to obtain the weight of the human body; after the semiconductor intelligent health scale is awakened, the semiconductor intelligent health scale can be directly switched to a nutrition mode, and then the weight of the tray 12 containing the food 13 is obtained, so that the weight of the food 13 is obtained. Since the calibration circuit 202 does not calibrate the electrical signal at the first electrical signal input terminal while in the sleep mode, calibration steps are reduced, and power consumption is reduced.
When weighing module 301 is used to weigh using sensors such as piezoresistive materials, calibration is required to obtain accurate results because the deformation of the piezoresistive material is not linear. In this embodiment, the weighing module 301 may output an analog electrical signal, and the controller 200 may receive the analog electrical signal of the weighing module 301, convert the analog electrical signal into a digital signal through the calibration circuit 202, and then address in the memory of the controller 200 to find the weight value stored in the memory corresponding to the digital signal, i.e., convert the digital signal into the weight value. The controller 200 includes a human body weight calibration range and a food weight calibration range, as well as a calibration electrical signal threshold. It should be noted that the body weight calibration range and the food weight calibration range, as well as the calibration electrical signal thresholds, may be stored in the memory of the controller 200. When the semiconductor intelligent health scale is in a dormant state and a human body stands on the scale body 10, even if the first electric signal obtained is not determined to be a signal corresponding to the weight of the human body or a signal corresponding to food 13, the calibration circuit 202 can compare the first electric signal with the threshold value of the calibration electric signal and determine whether the first electric signal is from the weight of the human body or the weight of the food 13. The calibration circuit 202 compares a first electrical signal with the calibration electrical signal threshold, determines the human body weight when the value of the first electrical signal is greater than the calibration electrical signal threshold, and determines the value of the weight corresponding to the value of the first electrical signal in the human body weight calibration range; when the value of the first electric signal is smaller than the calibration electric signal threshold value, the weight of the food 13 is determined, and after the value of the first electric signal is amplified, the value of the weight corresponding to the value of the first electric signal is determined in the food weight calibration range. Here, the value of the first electrical signal may be a value of an analog signal, such as a current, or a voltage; the value of the first electrical signal may refer to a value of the first electrical signal after being converted into a digital signal. To improve the measurement accuracy, the calibration circuit 202 may also amplify a smaller digital signal corresponding to the weight of the food 13, for example, amplifying the digital signal obtained by weighing the food 13 by 100 times, and then comparing the amplified digital signal with the calibrated range of the weight of the food to obtain a corresponding weight value. The calibration circuit 202 may not amplify the converted digital signal for an analog electric signal corresponding to, for example, the weight of a human body, so as to reduce the amount of calculation and increase the output speed while satisfying the accuracy. In one embodiment, the precision of measuring the weight of the human body is 0.01kg, and the precision of measuring the weight of food can be improved by 100 times to reach 0.0001 kg.
