Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of washing machines, and specifically to a method, device, electronic device and computer-readable storage medium for quantifying belt degradation. Background Art

[0002] The motor of the washing machine drives the inner drum of the washing machine to rotate through a belt. As the washing machine is used for a longer time, the belt will fail and will not be able to effectively transmit power. The failure of washing machine belts is mainly divided into sudden failure and degradation failure. Sudden failure is unpredictable, and degradation failure refers to the slow degradation of the transmission function of the washing machine belt over time. When it exceeds the critical failure point, the transmission function is completely lost. Degradation failure has predictable characteristics. However, the relevant technology lacks a method for predicting the degradation of washing machine belts. Summary of the invention

[0096] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0097] In one embodiment, Figure 1 As shown, a method for quantifying the amount of belt degradation is provided. Although a logical order is shown in the step diagram, in some cases, the steps shown or described may be performed in an order different from that shown in the figure. Specifically, the method for quantifying the amount of belt degradation can be applied to a microcontroller unit (MCU) in a washing machine.

[0098] It should be noted that the order of description of the following embodiments is not intended to limit the priority order of the embodiments.

[0099] according to Figure 1 The method for quantifying the amount of belt degradation shown in the figure includes at least steps S110 to S150, which are described in detail as follows:

[0100] In step S110, the current washing program of the washing machine and the weight of the current load are determined.

[0101] The laundry program is a pre-configured running program, and the multiple target speeds of the drum of the washing machine corresponding to the laundry program are also pre-configured. The laundry program includes but is not limited to: washing, dehydration, rinsing, drying and / or drum self-cleaning, etc., and washing can include but is not limited to: normal washing, delicate washing, heavy-duty washing and / or quick washing, etc.

[0102] The current load weight refers to the weight of the load in the drum of the washing machine. The weight of the load of the washing machine will affect the amount of belt degradation. The load in the drum of the washing machine usually includes clothes and / or water. The sensor in the washing machine can obtain the weight of the load in the drum of the washing machine and transmit the obtained weight to the microprocessor unit.

[0103] In step S120, according to the washing program, the rotation speed of the inner drum of the washing machine is controlled to reach various target rotation speeds.

[0104] The multiple target speeds of the washing machine drum corresponding to the washing program are pre-configured. Therefore, according to the current washing program, the number of target speeds and each target speed can be determined. According to each target speed configured in the washing program, the washing machine drum is controlled to rotate so that the speed of the washing machine drum reaches each target speed in sequence.

[0105] In step S130, the speed switching time corresponding to each of the target speeds is obtained, and the motor powers of the motor when the speed of the inner drum of the washing machine reaches each of the target speeds are obtained.

[0106] The speed switching time of the washing machine drum is affected by the washing machine belt. The speed of the washing machine drum can be obtained by a Hall effect sensor or a photoelectric sensor. According to the speed of the washing machine drum corresponding to each time, the speed switching time corresponding to each target speed can be obtained.

[0107] The motor power corresponding to each time is collected, and the motor power of each motor when the speed of the drum in the washing machine reaches each target speed is obtained. In one embodiment, the motor power can be obtained by a power meter, the power meter is connected to the power supply end of the motor, and then the motor is connected to the power meter, and the power meter will directly obtain the motor power. In another embodiment, the motor power can be determined by detecting the current flowing through the motor and the voltage at both ends of the motor, and the product of the current and the voltage.

[0108] In step S140, the historical operation time of the washing machine is obtained.

[0109] The running time of the washing machine will be recorded each time, and the historical running time of the washing machine can be obtained from the record.

[0110] In step S150, the degradation amount of the belt of the washing machine is determined according to the weight, the speed switching time, the motor power and the historical operation time.

[0111] In one embodiment, the degradation process of a washing machine belt can be modeled as:

[0112]

[0113] Where Y(t) represents the degradation amount of the washing machine belt; f represents the degradation path function; A is the code of the current washing program of the washing machine; W is the weight of the current load; n k Characterizes the target speed, Indicates the speed of the washing machine drum from n k-1 Convert to n k The time taken is defined as the speed switching time. Indicates that the speed of the washing machine drum reaches the target speed n k The motor power of the motor at , k = 1, 2, ..., k, k is a positive integer; t is the historical running time of the washing machine. A determines the speed n k The number and size of values, n k >n k-1 >…>n2>n1.

[0114] In another embodiment, taking into account the measurement error, the degradation process of a washing machine belt can be modeled as:

[0115]

[0116] Among them, ε is the measurement error, which obeys the normal distribution: ε~N(0,σ 2 ); the meanings of the remaining characters can be found in the previous text.

[0117] Based on the modeling of the above degradation process, the degradation path function f under a certain A can be expressed as:

[0118]

[0119] Where α is the load weight correction factor, is the speed correction coefficient matrix, is the power correction coefficient matrix, μ is the time correction coefficient, t represents the transpose of the matrix; the meanings of the remaining characters can be referred to in the previous text.

[0120] The load weight correction coefficient, speed correction coefficient matrix, power correction coefficient matrix and time correction coefficient corresponding to each washing program are pre-configured, and the load weight correction coefficient, speed correction coefficient matrix, power correction coefficient matrix and time correction coefficient corresponding to each washing program are calculated based on a large number of experiments or by building a model.

[0121] Figure 2 FIG. 1 is a flow chart of a method for quantifying belt degradation provided in an embodiment of the present application. Figure 2 As shown, after the washing machine is started, the current washing program is selected, and the speed n is determined according to the current washing program. kThe value size and number of , determine the running time of the washing program this time, and obtain the configured load weight correction coefficient, speed correction coefficient matrix, power correction coefficient matrix and time correction coefficient. Get the historical running time t of the washing machine and match the measurement error ε, then weigh the load and get the current load weight W. According to the determined n k The value size and number are used to control the speed of the washing machine drum to reach: n1, n 2, …,n k , record the speed n1,n 2, …,n k Time t n1 ,t n2 ,…,t nk , and calculate n1,n 2, …,n k Motor power P n1 ,P n2 ,…,P nk Then according to the formula Δt ni-1～ni =t ni -t ni-1 (i=1,2,…,k) to calculate the speed switching time. Finally, the current degradation amount Y(t) is calculated according to the modeling formula of the degradation process described above, and the historical running time of the washing machine is updated using the current running time of the washing machine, and the updated historical running time is recorded.

[0122] By adopting the technical solution of the embodiment of the present application, according to the current washing program of the washing machine, the speed of the drum in the washing machine can be controlled to reach various target speeds, thereby obtaining various speed switching times, and the various motor powers of the motor when the speed of the drum in the washing machine reaches each of the target speeds can also be obtained; the weight of the current load and the running time of the washing machine are also obtained, and then based on the weight, the various speed switching times, the various motor powers and the running time, the degradation amount of the washing machine belt can be determined, thereby realizing the quantification of the degradation amount of the washing machine belt, so as to predict the degradation failure of the washing machine, and take corresponding measures according to the degradation amount of the washing machine belt to ensure the normal operation of the washing machine.

[0123] Based on the above technical solution, Figure 2 As shown, after determining the degradation amount of the belt of the washing machine, the method may further include: determining the current operation time of the washing machine according to the current washing program of the washing machine; updating the historical operation time of the washing machine according to the current operation time of the washing machine; and recording the updated historical operation time.

[0124] The running time corresponding to each washing program is pre-configured. According to the current washing program of the washing machine, the running time of the washing machine can be determined. The sum of the running time of the washing machine and the historical running time of the washing machine is determined as the updated historical running time. The updated historical running time is used to overwrite the historical running time before the update, so that the degradation amount is calculated according to the updated historical running time when the washing machine is run next time.

[0125] Based on the above technical solution, as an embodiment, Figure 3 As shown, after determining the degradation amount of the washing machine belt, the method further includes: obtaining a degradation amount limit value Y M ; When the degradation amount of the washing machine belt is greater than the degradation amount limit value, an alarm is issued; when the degradation amount of the washing machine belt is not greater than the degradation amount limit value, a degradation amount threshold value Y is obtained C ; the degradation amount threshold is less than the degradation amount limit value; when the degradation amount of the washing machine belt is less than the degradation amount threshold, the washing machine is operated normally; when the degradation amount of the washing machine belt is not greater than the degradation amount limit value and not less than the degradation amount threshold, a target processing method for the washing machine belt is determined, and the washing machine is processed according to the target processing method.

[0126] The degradation amount of the washing machine belt reaches the degradation amount limit value, indicating that the washing machine belt has failed. The degradation amount of the washing machine belt reaches the degradation amount threshold value, indicating that the washing machine belt needs to be compensated for degradation. The degradation amount limit value and the degradation amount threshold value are pre-configured, and the degradation amount limit value and the degradation amount threshold value can be determined based on experience or big data. The degradation amount threshold value is less than the degradation amount limit value.

[0127] A degradation limit value is obtained. When the degradation amount of the washing machine belt is greater than the degradation limit value, the washing machine stops and an alarm is sounded to provide feedback to the user that the belt has failed and guide the user to report the belt for repair.

[0128] When the degradation amount of the washing machine belt is not greater than the degradation amount limit value, the degradation amount threshold is obtained. When the degradation amount of the washing machine belt is less than the degradation amount threshold, it is proved that the washing machine belt is not failed and no compensation is required. At this time, the washing machine can be operated normally according to the washing program.

[0129] When the degradation amount of the washing machine belt is not less than the degradation amount threshold and not greater than the degradation amount limit, it proves that the washing machine belt has degraded but has not failed. At this time, the washing machine belt can be processed according to the target processing method to make the washing machine belt continue to work. The target processing methods include alarm, normal operation of the washing machine, acceleration compensation and speed compensation. The following article will detail how to determine the target processing method corresponding to the washing machine belt.

[0130] By adopting the technical solution of the embodiment of the present application, by comparing the degradation amount of the washing machine belt with the degradation amount limit value and the degradation amount threshold value, it is possible to determine whether the washing machine belt has failed, and whether it needs to be processed if it has not failed, thereby discovering the degradation of the washing machine belt as early as possible and processing it, so as to extend the life of the washing machine belt.

[0131] On the basis of the above technical solution, as an embodiment, the target processing method for the washing machine belt is determined, including: obtaining the theoretical speed switching time; obtaining the compensation method determination coefficient, and determining the determination threshold according to the compensation method determination coefficient and the theoretical speed switching time; for each speed switching time corresponding to the target speed: when the speed switching time corresponding to the target speed is less than the theoretical speed switching time, determining the processing method as an alarm; when the speed switching time corresponding to the target speed is equal to the theoretical speed switching time, determining the processing method as normal operation of the washing machine; when the speed switching time corresponding to the target speed is greater than the theoretical speed switching time and less than the determination threshold, determining the processing method as acceleration compensation for the washing machine belt; and / or when the speed switching time corresponding to the target speed is not less than the determination threshold, determining the processing method as speed compensation for the washing machine belt; according to statistics of each of the determined processing methods, determining the target processing method from multiple processing methods.

[0132] The target speeds corresponding to the washing program form an arithmetic progression, and the theoretical speed switching time corresponding to each target speed is the same. The calculation formula for the theoretical speed switching time is as follows:

[0133]

[0134] Among them, t 理 is the theoretical speed switching time, a std This is the acceleration of the washing machine belt when it is working normally.

[0135] The compensation mode determination coefficient is used to determine whether to perform speed compensation or acceleration compensation on the washing machine. The compensation mode determination coefficient can be a constant determined by experience or big data and can be directly obtained. The compensation mode determination coefficient is greater than 1. The product of the compensation mode determination coefficient and the theoretical speed switching time is the determination threshold.

[0136] According to the relationship between the speed switching time corresponding to each target speed and the theoretical speed switching time, the processing method corresponding to the target speed can be determined. By statistics of the processing methods corresponding to each target speed, the target processing method for the washing machine can be determined.

[0137] The processing method corresponding to each target speed can be determined by the following formula:

[0138]

[0139] Among them, t 判 is the judgment threshold, t 判 =K t *t 理 , K t is the compensation method determination coefficient; t n is the speed switching time corresponding to the target speed n. n <t 理 When the alarm is determined as processing method A, t n =t 理 The normal operation of the washing machine is determined as treatment method B, and t 理 <t n <t 判 When acceleration compensation is performed, it is determined as processing method C, and tt n ≥t 判 When speed compensation is performed, it is determined as processing method D.

[0140] In one embodiment, determining the target processing method from the multiple processing methods based on the statistics of the determined processing methods may include: when the statistics of the alarm processing method are not zero, determining the target processing method to be an alarm; when the target processing method is not an alarm and the statistics of the processing method of normally operating the washing machine is greater than the sum of the statistics of the processing method of performing acceleration compensation on the washing machine belt and the statistics of the processing method of performing speed compensation on the washing machine belt, determining the target processing method to be performing speed compensation on the washing machine belt; when the target processing method is not an alarm or the washing machine is operated normally, and the statistics of the processing method of performing speed compensation on the washing machine belt is greater than the statistics of the processing method of performing acceleration compensation on the washing machine belt, determining the target processing method to be performing speed compensation on the washing machine belt; when the target processing method is not an alarm, the washing machine is operated normally, or the speed compensation is performed on the washing machine belt, determining the target processing method to be performing acceleration compensation on the washing machine belt.

[0141] Considering that when the speed switching time corresponding to the target speed is greater than the theoretical speed switching time, it proves that the speed of the washing machine is abnormal, so an alarm is needed. The speed is a user-sensitive parameter, so it is usually not adjusted, and the acceleration is a parameter that is difficult for users to perceive in the background. Therefore, the priority of the four processing methods can be determined as A>C>D>B.

[0142] Based on the above priorities, the target processing method of the washing machine can be determined as follows:

[0143]

[0144] By adopting the technical solution of the embodiment of the present application, a processing method can be determined according to the speed switching time corresponding to each target speed, and a target processing method can be determined from multiple processing methods by comparing the speed switching time corresponding to multiple target speeds with the theoretical speed switching time. In this way, the speed switching time corresponding to each target speed is taken into account, and the actual impact on the washing machine and the user's perception are taken into account, so the washing machine can be reasonably processed according to the determined target processing method.

[0145] Based on the above technical solution, as an embodiment, Figure 4 As shown, the target processing method is to perform acceleration compensation on the belt of the washing machine. The method may further include steps S210 to S240, which are described in detail as follows:

[0146] In step S210, the corresponding processing method is to obtain each target speed switching time for performing acceleration compensation on the washing machine belt.

[0147] When determining the target processing method, the processing method corresponding to the speed switching time corresponding to each target speed is determined, and the corresponding processing method is the speed switching time for acceleration compensation of the washing machine belt, which is determined as the target speed switching time, and the target speed switching time is obtained.

[0148] In step S220, the average time of each target speed switching time is obtained.

[0149] The average value of each of the target speed switching times is determined as the mean time.

[0150] In step S230, the compensated acceleration is determined according to the difference between the mean time and the theoretical speed switching time.

[0151] The acceleration is compensated according to the degree to which the speed of the drum in the washing machine deviates from the mean time to the theoretical speed switching time, thereby obtaining the compensated acceleration.

[0152] The compensated acceleration can be determined according to the following formula:

[0153] a mod =D a ·ln{E a [(t 均 -t 理 )+1]}·a std +F a ;

[0154] Among them, a mod is the acceleration after compensation, a stdis the acceleration of the washing machine belt during normal operation, t 均 is the mean time, t 理 is the theoretical switching time; D a 、E a and F a is the adjustment coefficient, so that the acceleration a after compensation mod and (t 均 -t 理 ) changes logarithmically to better fit the actual situation, D a 、E a and F a It may be determined empirically or experimentally.

[0155] In step S240, the motor is controlled to operate according to the compensated acceleration.

[0156] The compensated acceleration is used as the standard acceleration for controlling the motor operation. The scope of the compensated acceleration is until the end of the current washing program. The next time the washing program is run, it will still be run with the built-in acceleration of the program to determine the target processing method. If the target processing method is to compensate the acceleration of the washing machine, the compensated acceleration may change when the washing program is run next time.

[0157] By adopting the technical solution of the embodiment of the present application, a specific method for acceleration compensation of a washing machine is proposed. By performing acceleration compensation on the washing machine, the belt of the washing machine can work normally after compensation, thereby delaying the degradation of the belt of the washing machine.

[0158] Based on the above technical solution, as an embodiment, Figure 5 As shown, the target processing method is to perform speed compensation on the belt of the washing machine. The method may further include steps S310 to S340, which are described in detail as follows:

[0159] In step S310, the output speed of the motor is obtained, and the maximum speed reached by the inner drum of the washing machine when the motor maintains the output speed is obtained.

[0160] In step S320, a compensation speed is determined according to the difference between the output speed and the maximum speed.

[0161] In step S330, the compensated motor speed is determined according to the compensation speed and the output speed.

[0162] In step S340, the motor is controlled to operate according to the compensated motor speed.

[0163] When t ≥ t 判It proves that within the specified time range, the speed of the washing machine drum cannot reach the target speed, and the belt degradation is large, so the target speed needs to be compensated. For example, the washing machine drum is required to reach a speed of 1000r / min, but the belt degradation is large. Although the motor outputs a speed of 1000r / min, the speed reaching the washing machine drum through the belt is only 900r / min. Therefore, the motor needs to output a speed greater than 1000r / min at this time.

[0164] The compensation speed n can be determined by the following formula ad :

[0165] n ad =m·(n std -n);

[0166] Among them, n std is the motor speed before compensation, n is the maximum speed that the drum of the current washing machine can reach within the specified time range when the motor runs according to the command speed before compensation. m is the compensation magnification factor, m≥1, and the value of m is determined according to the specific washing machine model. When m=1, the amount of shortage is compensated.

[0167] The motor speed n after compensation can be determined by the following formula mod :

[0168]

[0169] Among them, n max is the motor's maximum speed. The meanings of the other characters can be found in the previous text.

[0170] According to the compensated motor speed, the motor is controlled to run, thereby realizing speed compensation for the washing machine.

[0171] By adopting the technical solution of the embodiment of the present application, a specific method for speed compensation of a washing machine is proposed. By performing speed compensation on the washing machine, the belt of the washing machine can work normally after compensation, thereby delaying the degradation of the belt of the washing machine.
