[0005] As an improvement of the above scheme, the initial abnormal rule includes: judging whether the working current is always greater than a first preset current threshold within a preset time; if the judgment is yes, it means that the preset initial abnormal rule is met; if the judgment is no, it means that the preset initial abnormal rule is not met.

If the judgment is yes, it indicates that the motor is in the second abnormal working state.

[0009] As an improvement of the above-mentioned scheme, the normal state rules include: calculating the working time of the motor after recovery; when the working time is equal to the preset working time, judging whether the proportion of time when the working current in the preset working time is less than or equal to the second preset current threshold is greater than a third preset ratio; if the judgment is no, it indicates that the motor is in a normal working state.

[0010] As an improvement of the above scheme, the step of optimizing and adjusting the motor according to the current working state includes: when the motor is in an abnormal working state, determining whether the number of times the motor is confirmed to be in an abnormal state is greater than a preset number, and if so, performing a motor fault alarm; if not, controlling the compressor and the motor to perform abnormal repair work, and re-determining the current working state of the motor and optimizing and adjusting the motor; when the motor is in a normal working state, restoring the compressor and the motor to normal operation.

[0021] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, a specific embodiment of the present invention provides a method for detecting abnormal noise of a motor frozen cylinder, which includes:

[0023] S101, obtaining the working current of the motor in real time;

[0024] S102, when the working current meets the preset initial abnormality rule, controlling the compressor and the motor to perform abnormality repair work;

[0025] Specifically, the initial abnormal rule includes: determining whether the working current is always greater than a first preset current threshold within a preset time; if so, it indicates that the preset initial abnormal rule is satisfied; if not, it indicates that the preset initial abnormal rule is not satisfied.

[0026] It should be noted that when the working current of the motor is always greater than the first preset current threshold within the preset time, it means that the preset initial abnormal rule is met, and the motor begins to be in an abnormal working state. For example, the motor is in an abnormal situation of abnormal noise from the freezing cylinder. At this time, the compressor and the motor are controlled to perform abnormal repair work to avoid damage to parts or the motor due to abnormal conditions; otherwise, it means that the preset initial abnormal rule is not met, and the motor is kept working normally.

[0027] The step of controlling the compressor and the motor to perform abnormal repair work includes:

[0028] Step 1, controlling the compressor and the motor to stop working at the same time, and calculating the stop working time;

[0029] It should be noted that when the motor starts to be in an abnormal working state, the compressor and the motor are controlled to stop working at the same time. On the one hand, it protects the motor, and on the other hand, it prevents the material temperature from being too low and causing the material to be too hard, affecting the normal working of the motor. At the same time, the stop working time is calculated to accurately control the working status of the compressor and the motor.

[0030] Step 2: When the stop working time is equal to the preset time threshold, the motor is restored to normal operation.

[0031] It should be noted that when the stop working time is equal to the preset time, the normal operation of the motor is restored, and the compressor continues to be stopped, so as to further determine the working condition of the motor later.

[0032] Preferably, the preset time threshold range is 6 minutes to 20 minutes, but not limited thereto.

[0033] S103, determining the current working state of the motor according to the working current and a preset motor state determination rule;

[0034] Specifically, the step of determining the current working state of the motor according to the working current and a preset motor state determination rule includes: when the working current meets the abnormal state rule, the motor is in an abnormal state; when the working current meets the normal state rule, the motor is in a normal state.

[0035] It should be noted that when the working current of the motor meets the abnormal state rules, it means that the motor is still in an abnormal working state, and subsequent optimization and adjustment work is needed to determine whether the motor can be adjusted and repaired; when the working current of the motor meets the normal state rules, it means that the motor has returned to a normal working state, and the motor and compressor are working normally to make ice.

[0036] Furthermore, the abnormal state rule includes a first abnormal state rule and a second abnormal state rule; the first abnormal state rule includes: determining whether the proportion of time during which the working current is greater than a first preset current threshold within a preset time is greater than a first preset ratio, and if the determination is yes, it indicates that the motor is in a first abnormal working state;

[0037] It should be noted that when the proportion of time when the motor's working current is greater than the first preset current threshold is greater than a first preset ratio within the preset time, it means that the motor is in an abnormal state with a more serious freezing cylinder noise. At this time, the motor's working current value is large, and the motor is likely to burn out if it is in this abnormal state for a long time.

[0038] Preferably, the first preset current threshold value range is 0.6A-1.5A, but is not limited thereto;

[0039] Preferably, the preset time range is 1-5 minutes, but not limited thereto;

[0040] Preferably, the first preset ratio is 3%, but not limited thereto;

[0041] For example, if the time when the motor's working current I is greater than 1.2A accounts for more than 3% within 3 minutes, that is, the cumulative time when the motor's working current I is greater than 1.2A accounts for 3% of the total time within 3 minutes, it means that the motor is in the first abnormal working state. At this time, regardless of whether the preset time of 3 minutes has been completed, the motor will be optimized and adjusted immediately.

[0042] The second abnormal state rule includes: determining whether the proportion of the time when the working current is less than or equal to the first preset current threshold and greater than the second preset current threshold within the preset time is greater than a second preset ratio. If the determination is yes, it indicates that the motor is in the second abnormal working state.

[0043] It should be noted that when within the preset time, the working current of the motor is less than or equal to the first preset current threshold and the proportion of time greater than the second preset current threshold is greater than the second preset ratio, it means that the motor is in an abnormal state of mild freezing and noise. At this time, the working current value of the motor is large. Being in this abnormal state for a long time may damage parts or even burn out the motor.

[0044] Preferably, the second preset current threshold range is 0.3-1A, but not limited thereto;

[0045] Preferably, the second preset ratio is 5%-50%, but not limited thereto;

[0046] For example, when within 3 minutes, the proportion of time when the working current I of the motor is less than 1.2A and the working current I is greater than or equal to 0.7A is greater than 17%, that is, within 3 minutes, the cumulative time when the working current I of the motor is less than 1.2A and the working current I is greater than or equal to 0.7A accounts for 3% of the total time, then it means that the motor is in the second abnormal working state. At this time, regardless of whether the preset time of 3 minutes has been completed, the motor will be optimized and adjusted immediately.

[0047] Furthermore, the normal state rules include:

[0048] Step 1, calculating the working time of the motor after recovery;

[0049] Step 2: When the working time is equal to the preset working time, determine whether the proportion of time during which the working current is less than or equal to the second preset current threshold in the preset working time is greater than a third preset ratio. If the determination is yes, it indicates that the motor is in a normal working state.

[0050] It should be noted that when the motor runs for the preset working time, if the proportion of time when the working current in the preset working time is less than or equal to the second preset current threshold is greater than the third preset ratio, it means that the motor is in a normal working state, and the working current of the motor is at a normal value.

[0051] Preferably, the preset working time threshold range is 6 minutes to 20 minutes, but is not limited thereto;

[0052] Preferably, the third preset ratio range is 60%-90%, but not limited thereto;

[0053] For example, after the motor has run for 3 minutes, during the 3 minutes of working time, the proportion of time when the motor's working current I is less than or equal to 0.7 A is greater than the third preset ratio.

[0054] S104, optimizing and adjusting the motor according to the current working state.

[0055] Specifically, the step of optimizing and adjusting the motor according to the current working state includes:

[0056] Step 1: when the motor is in an abnormal working state, determine whether the number of times the motor is confirmed to be in an abnormal state is greater than a preset number, if it is determined to be yes, perform a motor fault alarm, if it is determined to be no, control the compressor and the motor to perform abnormal repair work, and re-determine the current working state of the motor and optimize and adjust the motor;

[0057] Step 2: When the motor is in normal working condition, restore the compressor and the motor to normal working state.

[0058] It should be noted that when the motor is still in an abnormal working state, if the number of times the motor is considered to be in an abnormal state is less than or equal to a preset number of times, the compressor and the motor are controlled again to perform abnormal repair work, so that the compressor and the motor stop working for a period of time, and then determine whether the motor can work normally; when the motor resumes working, the current working state of the motor is re-determined, and the motor is optimized and adjusted again according to the working state until the motor is adjusted and restored to a normal working state. At this time, the compressor and the motor are controlled to perform normal ice making work, or when the number of times the motor is considered to be in an abnormal state is greater than a preset number of times, that is, after the preset number of optimization and adjustment work is cyclically performed, when the motor still cannot be detected and determined to be in an abnormal state, it is finally determined that the motor is faulty and cannot be adjusted and repaired. At this time, the motor fault alarm work is performed to promptly notify the user to perform motor maintenance processing. For example, multiple indicator lights on the control device are lit at the same time or the alarm light is lit to play a visual warning role; the alarm speaker can also be controlled to work to play an auditory warning role; an alarm signal can also be sent to the user's mobile terminal by wireless means to promptly notify the user to perform motor maintenance processing.

[0059] Preferably, the preset number of times ranges from 1 to 5 times, but is not limited thereto.

[0060] like Figure 2 As shown, the present invention also includes a motor freezing cylinder abnormal noise detection system, including:

[0061] Acquisition module 1, used to obtain the working current of the motor in real time;

[0062] The motor abnormality processing module 2 is used to control the compressor and the motor to perform abnormality repair work when the working current meets the preset initial abnormality rule;

[0063] Specifically, Figure 3 As shown, the motor abnormality processing module 2 includes: a motor judgment processing unit 21, which is used to judge whether the working current is always greater than a first preset current threshold within a preset time. If it is judged as yes, it means that the preset initial abnormality rule is met. If it is judged as no, it means that the preset initial abnormality rule is not met.

[0064] It should be noted that when the working current of the motor is always greater than the first preset current threshold within the preset time, it means that the preset initial abnormal rule is met, and the motor begins to be in an abnormal working state. For example, the motor is in an abnormal situation of abnormal noise from the freezing cylinder. At this time, the compressor and the motor are controlled to perform abnormal repair work to avoid damage to parts or the motor due to abnormal conditions; otherwise, it means that the preset initial abnormal rule is not met, and the motor is kept working normally.

[0065] Among them, Figure 3As shown, the motor abnormality processing module 2 also includes:

[0066] The motor abnormality processing unit 22 is used to control the compressor and the motor to stop working at the same time, and calculate the stop working time;

[0067] It should be noted that when the motor starts to be in an abnormal working state, the compressor and the motor are controlled to stop working at the same time. On the one hand, it protects the motor, and on the other hand, it prevents the material temperature from being too low and causing the material to be too hard, affecting the normal working of the motor. At the same time, the stop working time is calculated to accurately control the working status of the compressor and the motor.

[0068] The motor recovery processing unit 23 is used to recover the normal operation of the motor when the stop working time is equal to a preset time threshold.

[0069] It should be noted that when the stop working time is equal to the preset time, the normal operation of the motor is restored, and the compressor continues to be stopped, so as to further determine the working condition of the motor later.

[0070] Preferably, the preset time threshold range is 6 minutes to 20 minutes, but not limited thereto.

[0071] A motor state determination module 3, used to determine the current working state of the motor according to the working current and a preset motor state determination rule;

[0072] Specifically, Figure 4 As shown, the motor state determination module 3 includes: a motor state determination unit 31, which is used to determine that the motor is in an abnormal state when the working current meets the abnormal state rule; when the working current meets the normal state rule, the motor is in a normal state.

[0073] It should be noted that when the working current of the motor meets the abnormal state rules, it means that the motor is still in an abnormal working state, and subsequent optimization and adjustment work is needed to determine whether the motor can be adjusted and repaired; when the working current of the motor meets the normal state rules, it means that the motor has returned to a normal working state, and the motor and compressor are working normally to make ice.

[0074] Furthermore, the abnormal state rule includes a first abnormal state rule and a second abnormal state rule; the first abnormal state rule includes: determining whether the proportion of time during which the working current is greater than a first preset current threshold within a preset time is greater than a first preset ratio, and if the determination is yes, it indicates that the motor is in a first abnormal working state;

[0075] It should be noted that when the proportion of time when the motor's working current is greater than the first preset current threshold is greater than a first preset ratio within the preset time, it means that the motor is in an abnormal state with a more serious freezing cylinder noise. At this time, the motor's working current value is large, and the motor is likely to burn out if it is in this abnormal state for a long time.

[0076] Preferably, the first preset current threshold value range is 0.6A-1.5A, but is not limited thereto;

[0077] Preferably, the preset time range is 1-5 minutes, but not limited thereto;

[0078] Preferably, the first preset ratio is 3%, but not limited thereto;

[0079] For example, if the time when the motor's working current I is greater than 1.2A accounts for more than 3% within 3 minutes, that is, the cumulative time when the motor's working current I is greater than 1.2A accounts for 3% of the total time within 3 minutes, it means that the motor is in the first abnormal working state. At this time, regardless of whether the preset time of 3 minutes has been completed, the motor will be optimized and adjusted immediately.

[0080] The second abnormal state rule includes: determining whether the proportion of the time when the working current is less than or equal to the first preset current threshold and greater than the second preset current threshold within the preset time is greater than a second preset ratio. If the determination is yes, it indicates that the motor is in the second abnormal working state.

[0081] It should be noted that when within the preset time, the working current of the motor is less than or equal to the first preset current threshold and the proportion of time greater than the second preset current threshold is greater than the second preset ratio, it means that the motor is in an abnormal state of mild freezing and noise. At this time, the working current value of the motor is large. Being in this abnormal state for a long time may damage parts or even burn out the motor.

[0082] Preferably, the second preset current threshold range is 0.3-1A, but not limited thereto;

[0083] Preferably, the second preset ratio is 5%-50%, but not limited thereto;

[0084] For example, when within 3 minutes, the proportion of time when the working current I of the motor is less than 1.2A and the working current I is greater than or equal to 0.7A is greater than 17%, that is, within 3 minutes, the cumulative time when the working current I of the motor is less than 1.2A and the working current I is greater than or equal to 0.7A accounts for 3% of the total time, then it means that the motor is in the second abnormal working state. At this time, regardless of whether the preset time of 3 minutes has been completed, the motor will be optimized and adjusted immediately.

[0085] Furthermore, the normal state rules include:

[0086] Step 1, calculating the working time of the motor after recovery;

[0087] Step 2: When the working time is equal to the preset working time, determine whether the proportion of time during which the working current is less than or equal to the second preset current threshold in the preset working time is greater than a third preset ratio. If the determination is yes, it indicates that the motor is in a normal working state.

[0088] It should be noted that when the motor runs for the preset working time, if the proportion of time when the working current in the preset working time is less than or equal to the second preset current threshold is greater than the third preset ratio, it means that the motor is in a normal working state, and the working current of the motor is at a normal value.

[0089] Preferably, the preset working time threshold range is 6 minutes to 20 minutes, but is not limited thereto;

[0090] Preferably, the third preset ratio range is 60%-90%, but not limited thereto;

[0091] For example, after the motor has run for 3 minutes, during the 3 minutes of working time, the proportion of time when the motor's working current I is less than or equal to 0.7 A is greater than the third preset ratio.

[0092] The motor optimization and adjustment module 4 is used to optimize and adjust the motor according to the current working state.

[0093] Specifically, Figure 5 As shown, the motor optimization and adjustment module 4 includes:

[0094] The motor abnormality adjustment unit 41 is used to determine whether the number of times the motor abnormality is confirmed is greater than a preset number when the motor is in an abnormal working state, and if so, to perform a motor fault alarm; if not, to control the compressor and the motor to perform abnormality repair work, and to re-determine the current working state of the motor and optimize and adjust the motor;

[0095] The motor normal adjustment unit 42 is used to restore the compressor and the motor to normal operation when the motor is in a normal operating state.

[0096] It should be noted that when the motor is still in an abnormal working state, if the number of times the motor is considered to be in an abnormal state is less than or equal to a preset number of times, the compressor and the motor are controlled again to perform abnormal repair work, so that the compressor and the motor stop working for a period of time, and then determine whether the motor can work normally; when the motor resumes working, the current working state of the motor is re-determined, and the motor is optimized and adjusted again according to the working state until the motor is adjusted and restored to a normal working state. At this time, the compressor and the motor are controlled to perform normal ice making work, or when the number of times the motor is considered to be in an abnormal state is greater than a preset number of times, that is, after the preset number of optimization and adjustment work is cyclically performed, when the motor still cannot be detected and determined to be in an abnormal state, it is finally determined that the motor is faulty and cannot be adjusted and repaired. At this time, the motor fault alarm work is performed to promptly notify the user to perform motor maintenance processing. For example, multiple indicator lights on the control device are lit at the same time or the alarm light is lit to play a visual warning role; the alarm speaker can also be controlled to work to play an auditory warning role; an alarm signal can also be sent to the user's mobile terminal by wireless means to promptly notify the user to perform motor maintenance processing.

[0097] Preferably, the preset number of times ranges from 1 to 5 times, but is not limited thereto.
