As shown in fig. 1 to 5, an embodiment of the present invention provides a power compensation control method for an electrical appliance having a circuit board and a motor, including:
inputting a voltage signal to the circuit board;
acquiring a clock signal of a circuit board;
and controlling the motor to enter a power compensation process according to the clock signal.
According to the control method of the power compensation, the circuit board is provided with the single chip microcomputer, the resistor, the capacitor, the inductor and other components, the clock is arranged in the single chip microcomputer, in the prior art, due to the fact that the clock of the single chip microcomputer has an error, the fluctuation range of output power is large, when the actual clock is faster than the standard clock, the output power of the motor is too large, and when the actual clock is slower than the standard clock, the output power of the motor is too small. The invention compensates the power according to different clock signals, namely corrects the clock of the singlechip, the compensation comprises negative compensation and positive compensation, when the power output by the motor is overlarge, the power is reduced by the negative compensation, when the power output by the motor is too small, the power is increased by the positive compensation, the problem that the clock has errors is radically solved, the problem that the power fluctuation range is large due to clock signal errors is further solved, the power consistency and the uniformity of the motor of an electric appliance product are improved, and the quality of the electric appliance product is further improved. After the clock of the single chip microcomputer is corrected, the clock of the single chip microcomputer starts timing, when the clock of the single chip microcomputer times to a time value set by the timer, the silicon controlled rectifier is controlled to be conducted, and the motor starts to operate to output power outwards. Compared with the mode of collecting the motor current and the bus voltage constant power to adjust in real time in the prior art, the control method of the power compensation is realized only through an algorithm, has simple control logic, does not add new electronic elements, can be realized by adopting an original circuit board, and has low research and development difficulty and low input cost.
It should be noted that the control method of power compensation according to the embodiment of the present invention may be performed at least once before the electric product leaves a factory, or may be performed at least once during the use of the user, or may be performed at least once before leaving a factory, or may be performed at least once during each use of the user. In one embodiment, the control method of power compensation according to an embodiment of the present invention may be performed at least once before the electric product is shipped, and will be described as an example of a previous operation before the electric product is shipped.
In some embodiments of the present invention, as shown in fig. 2 and 5, acquiring the clock signal of the circuit board includes acquiring an actual number of clock steps of the circuit board within a fixed time; acquiring the step number of a standard clock within fixed time; determining the clock signal to be fast according to the fact that the actual clock step number is larger than the standard clock step number; and determining that the clock signal is slow according to the fact that the actual clock step number is smaller than the standard clock step number. As described above, power compensation is required differently between the case where the clock signal is fast and the case where the clock signal is slow, and a determination method of whether the clock signal is fast or slow will be described in detail below. The comparison between the fast and slow speed needs to be compared with a reference, so that the actual clock step number and the standard clock step number of the single chip microcomputer of the circuit board in a fixed time need to be obtained, if the actual clock step number is larger than the standard clock step number, the clock signal is determined to be fast, and the motor is controlled to enter a first power compensation process, namely a negative compensation process. And if the actual clock step number is smaller than the standard clock step number, determining that the clock signal is slow, and controlling the motor to enter a second power compensation process, namely a positive compensation process. The fixed time may be any time period, such as half a voltage signal period, an integer multiple of a voltage signal period, a quarter of a voltage signal period, and the like. In order to better describe the method for determining whether the clock signal is fast or slow, a specific numerical example is described below, in one voltage signal period, the standard clock step number of the single chip of the circuit board is 5 steps, the actual clock step number is 6 steps, and the clock signal can be determined to be fast. In a voltage signal period, the standard clock step number of the singlechip of the circuit board is 5 steps, the actual clock step number is 4 steps, and the clock signal can be determined to be slow.
In some embodiments of the present invention, as shown in fig. 5, controlling the motor to enter the first power compensation process according to the clock signal being fast includes controlling the motor to enter the first power compensation process according to the clock signal being fast; and controlling the motor to enter a second power compensation process according to the slow clock signal. As will be described in detail below, for different circuit boards, three situations exist in the clock signal of the single chip of the circuit board: first, the clock signal is faster than the standard clock signal, second, the clock signal is slower than the standard clock signal, and third, the clock signal is synchronized with the standard clock signal. When the clock signal is in the first condition, the power output by the motor is larger than the preset power, when the clock signal is in the second condition, the power output by the motor is smaller than the preset power, and when the clock signal is in the third condition, the power output by the motor is equal to the preset power. And aiming at the condition that the power output by the motor is equal to the preset power, power compensation is not needed. For the case that the output power of the motor is not equal to the preset power, different compensation processes need to be performed on the power. And controlling the motor to enter a first power compensation process to perform negative compensation to reduce the power under the condition that the first clock signal is fast, and controlling the motor to enter a second power compensation process to perform positive compensation to increase the power under the condition that the third clock signal is slow.
In some embodiments of the present invention, as shown in fig. 3 and 5, controlling the motor to enter the first power compensation process according to the clock signal being fast includes obtaining a standard delay step and a step adjustment coefficient of the motor; and calling a first power compensation function T1 to be T0+ k (T1-Ts), and calculating the actual delay step of the motor, wherein T1 is the actual delay step of the clock signal, T0 is the standard delay step, Ts is the standard clock step, T1 is the actual clock step, k is the step adjustment coefficient, and the value range of k is 0-1. According to the foregoing, when the clock signal is fast, which may cause that the time value set by the timer has not yet been reached, the thyristor is turned on in advance, which causes that the power output by the motor is too large, so that the delay time needs to be controlled to increase, and the turn-on time point of the thyristor is delayed backwards, thereby reducing the power output by the motor. The clock signal is fast, which means T1-Ts > 0, T1 ═ T0+ k (T1-Ts), that is, T1 is greater than T0, for different voltage signals, the following change of the adjustment coefficient k is compensated, k ═ Ts/T1, and the value range of k is 0-1. For each circuit board, the corresponding k value is fixed, the first power compensation function is determined, after power compensation is performed for one time before the electric product leaves a factory, the actual delay step length of the signal which is always fast can be obtained, and in the using process of a user, the time set by the timer is the actual delay step length.
In some embodiments of the present invention, as shown in fig. 4 and 5, controlling the motor to enter the second power compensation process according to the clock signal being slow includes obtaining a standard delay step and a step adjustment coefficient of the motor; and calling a second power compensation function T2 to be T0+ k (T1-Ts), and calculating the actual delay step of the motor, wherein T2 is the slow actual delay step of the clock signal, T0 is a standard delay step, Ts is a standard clock step, T1 is the actual clock step, and k is a step adjustment coefficient. According to the foregoing, when the clock signal is slow, the thyristor is not turned on and the output power of the motor is too low when the time value set by the timer is reached, so that the delay time needs to be controlled to be reduced, the turn-on time point of the thyristor is advanced, and the output power of the motor is increased. The clock signal is slow, which means T1-Ts < 0, T1 ═ T0+ k (T1-Ts), i.e. T1 is less than T0, for different voltage signals, the following change of the adjustment coefficient k is compensated, k ═ Ts/T1. For each circuit board, the corresponding k value is fixed, the second power compensation function is determined, after power compensation is performed for one time before the electric product leaves a factory, the actual delay step length when the signal is slow can be obtained all the time, and in the using process of a user, the time set by the timer is the actual delay step length.
In some embodiments of the invention, according to the foregoing, the circuit board or the electric product having the circuit board is required to be in a power-on state to perform the power compensation. As shown in fig. 5, the voltage signal is an ac signal, and the control of the output power of the motor is realized by controlling the on-time of the thyristor. In the period time of an alternating current signal, the period time comprises conduction time and delay time, the delay time corresponds to a control angle, and the conduction time corresponds to the conduction angle, namely the period time of the alternating current signal minus the control angle time is equal to the conduction angle time. After the first power compensation function is determined, a specific numerical value of the actual delay step length with the clock signal being fast in one alternating current signal period can be calculated, the numerical value is stored, when the next electric appliance product is used, the motor of the electric appliance product is controlled to run according to the actual delay step length with the clock signal being fast in each alternating current signal period, and compared with a mode of collecting the motor current and the bus voltage constant power to adjust in real time in the prior art, the control method of the power compensation does not need to adjust in real time, the calculation workload and the workload of the electric appliance product are reduced, the load of the electric appliance product is further reduced, and the service life of the electric appliance product is prolonged. Similarly, after the second power compensation function is determined, a specific numerical value of the actual delay step length of which the clock signal is slow in the period time of the alternating current signal can be calculated, the numerical value is stored, and when the electrical product is used next time, the motor of the electrical product is controlled to run according to the actual delay step length of which the clock signal is slow in each period time of the alternating current signal.
The frequency of the voltage signal used in various countries in the world is different, and the frequency of the voltage used in countries such as china, australia, india, japan is 50Hz, and the frequency of the voltage used in countries such as canada, usa, korea is 60 Hz.
In some embodiments of the present invention, the clock is corrected to eliminate the influence of the error of the clock on the power output by the motor, when the correction is performed, the actual clock step number and the standard clock step number within a fixed time need to be obtained, where the standard clock step number is not specifically a standard value, and the standard clock step number has two meanings, the first meaning is that the standard clock step number is the standard clock step number of the standard circuit board, that is, there is no error in the clock of the single chip of the circuit board, and the standard clock step number without error is used as the reference to determine whether the clock signal is fast or slow, and the standard constant step number of the standard circuit board is used as the standard to not only correct one circuit board, but also correct batches of a plurality of circuit boards, on one hand, the influence of the error of the clock on the power output by the motor can be eliminated, on the other hand, before the electric products leave a factory, power compensation is carried out on each electric product, the power output by the motor can be closer to the preset power, the difference among the electric products in the same batch is reduced, and the consistency and uniformity of the power are improved. Secondly, when batch correction is carried out on the condition of a plurality of circuit boards, the clock step number of any circuit board can be defined as a standard clock step number, and the standard clock step number is used as a reference to judge whether the clock signal is fast or slow. In one embodiment, the standard clock step count is a standard clock step count of a standard circuit board.
