[0001] The present application relates to the field of hairdressing, and in particular to a method and system for adjusting the power of hair clippers. Background Art

[0002] Electric hair clippers are widely used in the current hairdressing industry as a convenient haircutting tool. They use the electric motor to drive the blade to reciprocate at high speed to achieve the function of haircutting. Its basic principle is to convert electrical energy into mechanical energy, drive the blade to move quickly, and thus cut the hair.

[0003] Electric hair clippers have several advantages over traditional manual scissors. First, they can provide stable and continuous cutting force, reducing the barber's hand fatigue and improving work efficiency. Second, electric clippers can cut faster and achieve more precise hair design. In addition, many modern electric hair clippers are equipped with adjustable blades and a variety of accessories to meet different haircutting needs.

[0004] However, existing electric hair clippers have some limitations. Unlike manual scissors, they cannot adjust the cutting force to suit the different hair qualities of users, making it difficult to achieve a uniform effect. In addition, electric hair clippers also make a certain amount of noise when working, which can easily cause discomfort to users. Summary of the invention

[0018] A7, adjusting the motor voltage output to the motor of the electric hair clipper through the calculation control module according to the motor target voltage.

[0019] By adopting the above technical solution, the hair clipper power adjustment system can determine the movement state and motor load of the hair clipper through the acceleration sensor module and the current detection module, and intelligently adjust the motor power according to these data, so as to achieve precise cutting of different hair qualities. This dynamic adjustment can improve haircutting efficiency, reduce energy waste, extend the service life of hair clippers, and provide users with a more comfortable and personalized haircutting experience.

[0020] Optionally, the motor control strategy further includes the following steps for determining whether the electric hair clipper is in a moving state:

[0021] B1, calculate the corresponding acceleration mean value according to the acceleration data;

[0022] B2, if the acceleration mean is within a preset gravity threshold range, it is determined that the electric hair clipper is in a stationary state;

[0023] B3, if the acceleration mean is within a preset weightlessness threshold range, it is determined that the electric hair clipper is in a falling state;

[0024] B4: If the acceleration mean is not within the gravity threshold interval and is not within the weightlessness threshold interval, it is determined that the electric hair clipper is in a moving state.

[0025] By adopting the above technical solution, the hair clipper power adjustment system can judge the state of the electric hair clipper through acceleration data and corresponding threshold intervals, so as to further make different control operations to cope with different states.

[0026] Optionally, the motor control strategy further includes the following steps for determining whether the electric hair clipper is in a cutting state:

[0027] C1, calculates the corresponding current standard deviation based on the motor current data;

[0028] C2: If the current standard deviation is greater than a preset idling standard deviation threshold, it is determined that the electric hair clipper is in a cutting state.

[0029] By adopting the above technical solution, the hair clipper power adjustment system can determine whether the electric hair clipper is in the cutting state through the standard deviation of the motor current data. This method is simple and effective, and does not require complex sensors to achieve accurate judgment of the working state of the hair clippers. By setting a suitable idling standard deviation threshold, the system can flexibly adapt to different types and models of electric hair clippers.

[0030] Optionally, the hair quality determination algorithm comprises the following steps:

[0031] D1, calculate the corresponding acceleration standard deviation based on the acceleration data;

[0032] D2, calculating the corresponding hair quality coefficient according to the current standard deviation, the preset current weight coefficient, the acceleration standard deviation, the preset acceleration weight coefficient and the preset adjustment coefficient, wherein the hair quality coefficient is calculated by the following calculation formula:

[0035] By adopting the above technical solution, the hair clipper power adjustment system can quantitatively reflect the hair quality of the user by comprehensively analyzing the acceleration and current data, thereby providing a data basis for adjusting the voltage and power of the motor of the electric hair clipper to achieve more precise adjustment.

[0036] Optionally, the motor adjustment algorithm comprises the following steps:

[0037] E1, when the duration of the electric hair clipper being in a stationary state exceeds a preset power-saving duration threshold, setting the motor target voltage to a preset power-saving voltage;

[0038] E2, when the electric hair clipper is in a falling state, the motor target voltage is set to a preset shut-off voltage;

[0039] E3, when the electric hair clipper is in a cutting state, the corresponding motor target voltage is calculated according to a preset standard voltage and a hair quality coefficient.

[0040] By adopting the above technical solution, the hair clipper power adjustment system can improve the safety and energy efficiency of the equipment by executing different voltage control strategies according to different working states of the hair clippers. In the static state, the system saves energy by automatically switching to the power saving mode; in the falling state, the system can quickly cut off the power supply to ensure safe use; in the cutting state, the system dynamically adjusts the voltage according to the hair quality characteristics to ensure the best cutting effect. This multi-scenario adaptive control strategy not only improves the intelligence level of the hair clippers, but also extends the service life of the equipment and reduces energy waste, while providing users with a safer, more comfortable and personalized haircutting experience.

[0041] Optionally, the motor control strategy further includes the following steps for adjusting the motor voltage:

On the one hand, sudden voltage adjustment can be avoided to reduce the risk of damaging the motor. On the other hand, when the electric hair clipper cuts hair, it usually cuts from the edge to the inside, and the hair on the edge is half sparse and the hair on the inside is dense. By gradually adjusting the voltage, it can also adapt to the changes in the density of the hair.

[0048] The present application also provides a method for adjusting the power of a hair clipper, comprising the following steps:

[0050] G2, judging whether the electric hair clipper is in a moving state according to the acceleration data;

[0062] Figure 2 The present invention is a schematic diagram of a process of adjusting the power of a hair clipper. DETAILED DESCRIPTION

[0063] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0064] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0065] refer to Figure 1 The present invention provides a hair clipper power adjustment system, which is used to judge the thickness and density of a customer's hair during a haircut, and adjust the motor voltage of the hair clipper according to the thickness and density of the customer's hair, so that the hair clipper can maintain a good cutting effect on hair of different hair qualities.

[0066] The hair clipper power adjustment system comprises:

[0067] The acceleration sensor module 10 is used to obtain acceleration data of the electric hair clipper 100 when it moves;

[0068] An ADC current detection module 20, used to obtain current data of the motor 101 of the electric hair clipper 100;

[0069] The calculation control module 30 is used to calculate the acquired data and control the power of the motor 101 of the electric hair clipper 100;

[0070] The acceleration sensor module 10 and the ADC current detection module 20 are respectively communicatively connected to the operation control module 30, the acceleration sensor module 10 is arranged on the electric hair clipper 100, the ADC current detection module 20 is electrically connected to the motor 101 of the electric hair clipper 100, and the operation control module 30 is electrically connected to the motor 101 of the electric hair clipper 100.

[0071] The acceleration sensor module 10 is mainly used to obtain acceleration data of the electric hair clipper 100 to determine whether the electric hair clipper 100 is in a moving state.

[0072] The ADC current detection module 20 is mainly used to detect the current value of the motor 101 of the electric hair clipper 100, and to determine the load condition of the motor 101 according to the current value, and then estimate the thickness and density of the customer's hair.

[0073] The operation control module 30 is mainly used to operate the respective data, and adjust the voltage value output to the motor 101 according to the operation result, so as to change the cutting effect of the electric hair clipper 100 to adapt to different hair qualities; for example, when the current value of the motor 101 is high, it can be estimated that the user's hair is coarse or thick, and the voltage value output to the motor 101 can be increased to improve the cutting effect. On the contrary, when the current value of the motor 101 is low, it can be estimated that the user's hair is fine or sparse, and the voltage value output to the motor 101 can be reduced, thereby ensuring the cutting effect while reducing the energy consumption and noise of the electric hair clipper 100.

[0074] Through the above technical scheme, the hair clipper power adjustment system can monitor the movement state and motor load of the hair clippers in real time, and adjust the motor voltage according to actual usage, thereby adjusting the motor output power. This can not only optimize the hair cutting effect, but also extend the service life of the motor and improve energy efficiency.

[0075] Furthermore, the hair clipper power adjustment system further includes a motor control strategy, and the motor control strategy includes the following steps:

[0076] A1, acquiring acceleration data through the acceleration sensing module 10 according to a preset first time window;

[0077] The first time window is a preset time window, which is used to obtain the acceleration data of the electric hair clipper 100 within a corresponding time range, and can be manually set according to needs or experience;

[0078] The acceleration data is a collection of all acceleration values ​​of the electric hair clipper 100 acquired by the acceleration sensor module 10 within the first time window.

[0079] A2, judging whether the electric hair clipper 100 is in a moving state according to the acceleration data;

[0080] Whether the electric hair clipper 100 is in a moving state can be determined based on the acceleration data through a variety of methods or algorithms. For example, a corresponding acceleration threshold is set. If the acceleration value exceeds the entire threshold, it can be considered that the electric hair clipper 100 is in a moving state; or the standard deviation of the acceleration is calculated. Generally, in a stationary state, the standard deviation of the acceleration is small, while the standard deviation of the moving state is large; or a spectrum analysis is performed. By performing algorithms such as fast Fourier transform on the acceleration data, the time domain-based data is converted into frequency domain data, and the moving state or the stationary state is distinguished according to the characteristics of the frequency domain data; or the acceleration data is integrated based on time to obtain the speed. If the speed exceeds a certain speed threshold, it can be determined to be a moving state.

[0081] A3, if the judgment result is that the motor is in a moving state, the motor current data is obtained through the ADC current detection module 20 according to the preset second time window;

[0082] The second time window is a preset time window, which is used to obtain the current data of the motor 101 of the electric hair clipper 100 within a corresponding time range;

[0083] The motor current data is a collection of current values ​​of the motor 101 of the electric hair clipper 100 when it is running in the second time window.

[0084] A4, judging whether the electric hair clipper 100 is in a cutting state according to the motor current data;

[0085] It is possible to determine whether the electric hair clipper 100 is in a cutting state by using a variety of algorithms based on the motor current data, because when the cutter of the electric hair clipper 100 is cutting hair, it will generate a certain resistance to the motor 101 to increase the load of the motor, thereby causing the current of the motor 101 to change. Therefore, it is possible to determine whether it is in a cutting state by the change in the current;

[0086] For example, the standard deviation of the motor current data can be calculated. If the standard deviation exceeds a certain threshold, it can be determined to be in a cutting state; or it can be compared with the idling current measured in advance. When the measured current data exceeds the idling current for a certain period of time, it can be determined to be in a cutting state.

[0087] A5, if the judgment result is that the hair is in the cutting state, the corresponding hair quality coefficient is calculated according to the motor current data and the acceleration data using a preset hair quality judgment algorithm;

[0088] The hair quality judgment algorithm is a pre-set algorithm, which estimates the customer's hair quality based on the motor current data and the acceleration data, so as to adjust the output voltage of the motor 101 of the electric hair clipper 100 accordingly, thereby facilitating cutting of different types of hair quality;

[0089] When the electric hair clipper 100 encounters thicker or denser hair, the motor load will increase, resulting in a change in current. On the other hand, the acceleration sensor can detect the moving speed of the hair clipper. When encountering thicker or denser hair, the movement of the hair clipper may slow down. Therefore, the thickness or density of the hair can be estimated by combining the motor current data and the acceleration data.

[0090] The hair quality coefficient is a value estimated based on the motor current data and the acceleration data, and reflects the thickness or density of the hair quality, that is, reflects the cutting difficulty of the electric hair clipper 100 when cutting hair.

[0091] A6, calculating the motor target voltage of the motor 101 of the electric hair clipper 100 according to the hair quality coefficient using a preset motor adjustment algorithm;

[0092] The motor adjustment algorithm is a pre-set algorithm for adjusting the voltage value output to the motor 101 of the electric hair clipper 100 according to the hair quality coefficient, so that the electric hair clipper 100 can better cut different hair qualities;

[0093] The motor target voltage is the voltage to be output to the motor 101 that needs to be adjusted.

[0094] A7, adjusting the motor voltage output to the motor 101 of the electric hair clipper 100 through the calculation control module 30 according to the motor target voltage.

[0095] The voltage value output to the motor 101 is adjusted by the operation control module 30 , and the corresponding output voltage can be adjusted by PWM.

[0096] Through the above steps, the hair clipper power adjustment system can determine the motion state and motor load of the hair clipper through the acceleration sensor module and the current detection module, and intelligently adjust the motor power according to these data, so as to achieve precise cutting of different hair qualities. This dynamic adjustment can improve haircutting efficiency, reduce energy waste, extend the service life of hair clippers, and provide users with a more comfortable and personalized haircutting experience.

[0097] Furthermore, the motor control strategy further includes the following steps for determining whether the electric hair clipper 100 is in a moving state:

[0098] B1, calculate the corresponding acceleration mean value according to the acceleration data;

[0099] The acceleration mean is the average value of the acceleration data, which may be an arithmetic mean or a weighted mean. By calculating the acceleration mean, the influence of noise signals in the data may be reduced.

[0100] B2, if the acceleration mean is within the preset gravity threshold range, it is determined that the electric hair clipper 100 is in a stationary state;

[0101] The gravity threshold interval is a preset value interval, which is used to determine whether the electric hair clipper 100 is in a stationary state. In the stationary state, the electric hair clipper 100 will only measure the acceleration data generated by gravity, that is, g. Considering the noise factors such as vibration in the external environment, a reasonable threshold interval is set, which can be used to determine whether the electric hair clipper 100 is only affected by gravity, that is, in a stationary state. For example, the gravity threshold interval can be set to 9.7m / s 2 Up to 9.9m / s 2 , when the acceleration mean falls within the interval, it can be determined that the electric hair clipper 100 is in a stationary state;

[0102] Furthermore, the voltage of the motor can be reduced or the motor can be turned off in a stationary state to reduce additional energy consumption and reduce the noise generated.

[0103] B3, if the acceleration mean is within a preset weightlessness threshold range, it is determined that the electric hair clipper is in a falling state;

[0104] The weightlessness threshold interval is a preset value interval, which is used to determine whether the electric hair clipper 100 is in a free fall state. Since the acceleration value measured by the electric hair clipper 100 should be close to 0 during free fall, the corresponding threshold interval can be used to determine whether the electric hair clipper 100 is in a free fall state. For example, the weightlessness threshold interval can be set to 0m / s 2 To 0.1m / s 2 ;

[0105] Furthermore, the voltage output to the motor 101 can be reduced to 0 in the falling state to shut down the movement of the motor 101, thereby avoiding the scattering of components in the impact after falling and reducing damage to the surroundings.

[0106] B4, if the acceleration mean is not within the gravity threshold interval and is not within the weightlessness threshold interval, it is determined that the electric hair clipper 100 is in a moving state;

[0107] When the acceleration mean is neither within the gravity threshold interval nor within the weightlessness threshold interval, it can be considered that the electric hair clipper 100 is in a moving state, that is, it may be in the hands of a barber and may be used for hair cutting at any time.

[0108] Through the above steps, the hair clipper power adjustment system can judge the state of the electric hair clipper through the acceleration data and the corresponding threshold range, so as to further make different control operations to deal with different states.

[0109] Furthermore, the motor control strategy further includes the following steps for determining whether the electric hair clipper is in a cutting state:

[0110] C1, calculates the corresponding current standard deviation based on the motor current data;

[0111] The current standard deviation is the corresponding standard deviation calculated based on the motor current data.

[0112] C2: If the current standard deviation is greater than a preset idling standard deviation threshold, it is determined that the electric hair clipper 100 is in a cutting state.

[0113] The idling standard deviation threshold is a pre-measured or set standard deviation of current data of the motor 101 of the electric hair clipper 100 in an idling state. Usually, the standard deviation of the current in the idling state is small. When cutting hair, the current will increase when the cutter is cutting hair, and the current will decrease when the cutter is reset, thereby forming fluctuations in the current data and increasing the corresponding standard deviation. Therefore, it can be further used as a basis for judging whether the electric hair clipper 100 is in a cutting state.

[0114] Through the above steps, the hair clipper power adjustment system can determine whether the electric hair clipper is in the cutting state through the standard deviation of the motor current data. This method is simple and effective, and does not require complex sensors to achieve accurate judgment of the working state of the hair clippers. By setting a suitable idling standard deviation threshold, the system can flexibly adapt to different types and models of electric hair clippers.

[0115] Furthermore, the hair quality determination algorithm comprises the following steps:

[0116] D1, calculate the corresponding acceleration standard deviation based on the acceleration data;

[0117] The acceleration standard deviation is the standard deviation corresponding to the acceleration data.

[0118] D2, calculating the corresponding hair quality coefficient according to the current standard deviation, the preset current weight coefficient, the acceleration standard deviation, the preset acceleration weight coefficient and the preset adjustment coefficient, wherein the hair quality coefficient is calculated by the following calculation formula:

[0119] H=(aI D +bA D )÷c,

[0120] Among them, H is the hair quality coefficient, I D is the current standard deviation, a is the current weight coefficient corresponding to the current standard deviation, A D is the acceleration standard deviation, b is the acceleration weight coefficient corresponding to the acceleration standard deviation, and c is the adjustment coefficient, where a+b=1.

[0121] Through the above steps, the hair clipper power adjustment system can quantitatively reflect the hair quality of the user by comprehensively analyzing the acceleration and current data, and then provide a data basis for adjusting the voltage and power of the motor of the electric hair clipper to achieve more accurate adjustment.

[0122] Furthermore, the motor adjustment algorithm comprises the following steps:

[0123] E1, when the duration of the electric hair clipper 100 being in a stationary state exceeds a preset power-saving duration threshold, the motor target voltage is set to a preset power-saving voltage;

[0124] The power saving time threshold is a preset time, which is used to determine whether the electric hair clipper 100 in a stationary state should be controlled and adjusted to reduce its voltage, reduce its energy consumption in a non-working state, and also reduce the noise generated by it;

[0125] The power-saving voltage is a preset reference voltage value, which is used to reduce the voltage to a corresponding value when the electric hair clipper 100 is in a non-working state, so as to reduce energy consumption and noise. The power-saving voltage can be set to 0 or a smaller value.

[0126] E2, when the electric hair clipper 100 is in a falling state, the motor target voltage is set to a preset shut-off voltage;

[0127] The shutdown voltage is a preset reference voltage value, which is used to reduce the voltage output to the motor 101 of the electric hair clipper 100 to a shutdown state. Usually, the shutdown voltage can be 0.

[0128] E3, when the electric hair clipper is in a cutting state, the corresponding motor target voltage is calculated according to a preset standard voltage and a hair quality coefficient;

[0129] The standard voltage is a preset voltage reference value, which is used to determine the default working voltage of the electric hair clipper 100, and can be set manually or based on experience. For example, the standard voltage can be half of the rated voltage of the motor 101;

[0130] Furthermore, the corresponding motor target voltage can be calculated according to the standard voltage and the hair quality coefficient by different calculation methods. For example, under the premise of not exceeding the rated voltage, the standard voltage is multiplied by the hair quality coefficient to obtain the motor target voltage to adapt to different hair qualities.

[0131] Through the above steps, the hair clipper power adjustment system can improve the safety and energy efficiency of the equipment by executing different voltage control strategies according to different working states of the hair clippers. In the static state, the system saves energy by automatically switching to the power saving mode; in the falling state, the system can quickly cut off the power supply to ensure safe use; in the cutting state, the system dynamically adjusts the voltage according to the hair quality characteristics to ensure the best cutting effect. This multi-scenario adaptive control strategy not only improves the intelligence level of the hair clippers, but also extends the service life of the equipment and reduces energy waste, while providing users with a safer, more comfortable and personalized haircutting experience.

[0132] Furthermore, the motor control strategy further includes the following steps for adjusting the motor voltage:

[0133] F1, obtaining the current voltage of the motor 101 of the electric hair clipper 100;

[0134] The current voltage is the current working voltage of the motor 101 of the electric hair clipper 100 .

[0135] F2, calculate the corresponding voltage adjustment value based on the difference between the current voltage and the motor target voltage;

[0136] The voltage adjustment value is the difference between the current voltage and the motor target voltage, that is, the adjustment amount that needs to be reduced.

[0137] F3, calculating the corresponding voltage unit displacement adjustment value according to the quotient of the voltage adjustment value and the preset adjustment displacement;

[0138] The adjustment displacement is a preset displacement reference value, which is used to determine the displacement distance for voltage adjustment;

[0139] The voltage unit displacement adjustment value is the amount of voltage adjustment required for each unit displacement;

[0140] For example, assuming that the voltage adjustment value is 1V and the adjustment displacement is 10cm, the voltage unit displacement adjustment value may be 0.1V / cm, that is, for every 1cm displacement of the electric hair clipper 100, the voltage output to the drip 101 is increased by 0.1V, until the displacement reaches 10cm and the voltage is increased by 1V.

[0141] F4, calculating the cumulative displacement value of the electric hair clipper 100 according to the acceleration data;

[0142] The cumulative displacement value is a cumulative value of the displacement values ​​of the electric hair clipper 100 calculated based on the acceleration data.

[0143] F5, adjusting the motor voltage output to the motor 101 of the electric hair clipper 100 according to the accumulated displacement value and the voltage unit displacement adjustment value until the motor target voltage is reached;

[0144] The output voltage is adjusted in real time according to the accumulated displacement value and the voltage unit displacement adjustment value until the motor target voltage is reached.

[0145] Through the above steps, the hair clipper power adjustment system can calculate the displacement of the electric hair clipper through acceleration data, and gradually adjust the voltage value of the output value motor according to the displacement of the electric hair clipper. On the one hand, sudden voltage adjustment can be avoided to reduce the risk of damaging the motor. On the other hand, when the electric hair clipper cuts hair, it usually cuts from the edge to the inside, and the hair on the edge is half sparse and the inside is dense. By gradually adjusting the voltage, it can also adapt to the changes in the density of the hair.

[0146] refer to Figure 2 The present application also provides a hair clipper power adjustment method for adjusting the motor output power of the electric hair clipper, comprising the following steps:

[0147] G1, acquiring acceleration data according to a preset first sliding window;
