The following are detailed descriptions.

[0078] Embodiment 1

[0079] See also Figure 1 , Figure 1 : is a flow chart of a method for detecting the operation of a motor with load disclosed in an embodiment of the present invention. Figure 1 The described method for detecting the operation of a motor with load can be applied to a device for detecting the operation of a motor with load, and the embodiment of the present invention does not limit this. Figure 1 As shown, the method for detecting the operation of a motor with load may include the following operations:

[0080] 101. When a start instruction for the motor is detected, a load detection is performed on the motor according to the start instruction to obtain a load detection result for the motor, where the load detection is used to determine a connection status between the load on the motor and the motor.

[0081] In the embodiment of the present invention, specifically, the load on the motor may be a motor rotor, such as a stirring head; thereby forming a combination of the motor and the stirring head. Correspondingly, the actual application device of the configuration combination of the motor and the stirring head may be a milk frother.

[0082] 102. Determine whether the load detection result indicates that the motor meets the preset normal operating conditions.

[0083] 103. When it is determined that the load detection result indicates that the motor meets normal operating conditions, a first operating identifier for the motor is generated, and a first operating control is performed on the motor according to the first operating identifier to control the rotation of the motor.

[0084] In the embodiment of the present invention, the first operation identifier indicates that the motor meets the preset normal operating conditions, and then the first operation control is executed, that is, the motor is controlled to rotate normally to ensure that the motor runs efficiently under safe load conditions; while the second operation identifier indicates that the motor does not meet the normal operating conditions, and the second operation control is executed at this time, which not only outputs an abnormal prompt to warn the operator, but also immediately terminates the power supply to the motor, effectively preventing potential safety hazards and further equipment damage, and embodies a high degree of intelligence and safety.

[0085] 104. When it is determined that the load detection result indicates that the motor does not meet the normal operating conditions, a second operating identifier for the motor is generated, and a second operating control is performed on the motor according to the second operating identifier. The second operating control is used to output an abnormal prompt indicating that the motor has an operating abnormality, and is also used to terminate the power supply to the motor.

[0086] In the embodiment of the present invention, specifically, the abnormal prompt indicating that the motor has an abnormal operation may be implemented by an alarm component connected to the motor, and the alarm component may be a buzzer, an indicator light, and the like.

[0087] It can be seen that the implementation Figure 1 The described loaded motor operation detection method immediately performs load detection after receiving a start-up command for the motor, thereby ensuring instant confirmation of the connection status between the motor and the load before starting, effectively avoiding motor failure or abnormal operation due to improper load connection, thereby helping to improve the real-time and accuracy of motor operation monitoring; further, according to different load detection results, it can intelligently generate a first operation identification or a second operation identification for the motor, and execute an adapted first or second operation control, that is, through this load detection, it can discover and deal with potential problems before the motor runs in advance, such as poor load connection, thereby effectively preventing possible failures of the motor during operation; at the same time, when the motor runs abnormally, it can quickly locate the problem and take corresponding measures, such as outputting abnormal prompts and terminating power supply, which provides convenience for subsequent fault diagnosis and repair, and helps to reduce maintenance costs.

[0088] In an optional embodiment, the above step 101 performs load detection on the motor according to the start instruction, and the method of obtaining the load detection result for the motor specifically includes:

[0089] Calling a running detection program for the motor according to the start command, and generating a test voltage for the motor according to the running detection program; the test voltage is used to control the preset test time of the motor start;

[0090] Perform a power supply test on the motor according to the test voltage, and collect the test parameters corresponding to the motor under the test voltage, the test parameters at least include feedback current, the feedback current includes a stable current value and a current change rate; the stable current value is a current value among several current values ​​collected when performing a power supply test on the motor, the duration of which remains unchanged is greater than the calculated duration; the current change rate is the current change rate at the moment of power supply to the motor;

[0091] The feedback current, the preset test time, and the test voltage are determined as the load detection result for the motor.

[0092] In this optional embodiment, after receiving the start command, the operation detection program for the motor is first called, and the program can generate a specific test voltage to control the start of the motor and run the preset test duration, thereby ensuring that the motor performs load detection under safe conditions and avoiding the risks that may be caused by direct starting. The component that generates the test voltage can be a PCB board associated with the motor.

[0093] In this optional embodiment, the motor is powered on and tested by a test voltage, and key test parameters such as the feedback current of the motor under the test voltage are collected, thereby being able to accurately reflect the load state of the motor.

[0094] In this optional embodiment, the feedback current included in the collected test parameters further includes multiple dimensional parameters such as stable current value and current change rate, wherein the stable current value is the current value that remains unchanged for a period longer than the calculated period during the power supply test, which reflects the load characteristics of the motor in a stable state; and the current change rate is the current change rate at the moment of power supply to the motor, which reveals the dynamic response characteristics of the motor when starting.

[0095] In this optional embodiment, the collected key parameters such as feedback current, preset test duration, test voltage, etc. are integrated into the load detection results for the motor, which not only realizes the intelligent processing of data, but also provides a reliable basis for subsequent operation control. For example, by comparing the load detection results with the preset normal operating conditions, it can intelligently determine whether the motor meets the operation requirements, so as to take corresponding operation control measures.

[0096] It can be seen that in this optional embodiment, the detection program set up can ensure that the motor can perform load detection under safe conditions, avoiding the risks that may be caused by direct startup; at the same time, multi-dimensional test parameters can be integrated as the load detection results of the motor, which is beneficial to improve the accuracy and reliability of determining the corresponding load detection results of the motor.

[0097] In another optional embodiment, the method of determining whether the load detection result indicates that the motor meets the preset normal operating conditions in step 102 specifically includes:

[0098] Obtaining rated current information recorded for the motor; the rated current information includes a first current interval and a second current interval, the first current interval being a correspondingly recorded power-on current interval when the motor is normally connected to the load; the second current interval being a correspondingly recorded power-on current interval when the motor is unloaded;

[0099] Determining whether the feedback current has a first current value that matches the first current interval; when it is determined that the feedback current has a first current value that matches the first current interval, determining that the motor meets a preset normal operating condition;

[0100] When it is determined that the feedback current does not have a first current value that matches the first current interval, it is determined whether the feedback current has a second current value that matches the second current interval, and when it is determined that the feedback current has a second current value that matches the second current interval, it is determined that the motor meets a preset first abnormal condition;

[0101] When it is determined that the feedback current does not have a second current value matching the second current interval, it is determined that the motor meets a preset second abnormal condition.

[0102] In this optional embodiment, the connection state includes a first state indicating that the load is normally connected to the motor or a second state opposite to the first state, and the second state includes a first sub-state or a second sub-state; the first sub-state is used to indicate that the motor is not connected to the load; the second sub-state is used to indicate that the motor is connected to the load and the load has an operating fault, and / or, is used to indicate that there is an abnormality in the connection path between the motor and the load;

[0103] When the motor meets normal operating conditions, the load and the motor are in a first state;

[0104] When the motor meets the first abnormal condition, the load and the motor are in the first sub-state; when the motor meets the second abnormal condition, the load and the motor are in the second sub-state.

[0105] In this optional embodiment, by setting a first current interval (a power-on current interval corresponding to when the motor is normally connected to the load) and a second current interval (a power-on current interval recorded when the motor is unloaded), a clear reference standard is provided for determining the load connection status of the motor.

[0106] In this optional embodiment, specifically, the specific value of the first current interval can be [0.048, 0.051], and this first current interval is the power-on current when the motor is loaded with a correct load and the motor and the load are operating normally; the specific value of the second current interval can be [0, 0.048), and this second current interval is the feedback current of the motor idling when the motor is not loaded with a load; or, it can be the feedback current of the motor when the motor is loaded with an incompatible load; or, the motor is loaded with a compatible load, but at least one component in the motor and / or the load has an abnormal operating current.

[0107] It can be seen that in this optional embodiment, by judging whether the feedback current falls into these intervals, different operating states of the motor can be accurately distinguished, including normal operation, load not connected (first abnormal condition) and connection abnormality or load failure (second abnormal condition), thereby improving the accuracy of judging the connection state between the motor and the load; further, the connection state can be subdivided into a first state indicating that the load is normally connected to the motor, a first sub-state indicating that the load is not connected, and a second sub-state indicating that the connection is abnormal or the load is faulty. This detailed classification method is conducive to improving the accuracy of identifying the operating state of the motor.

[0108] In yet another optional embodiment, the test parameter further includes a feedback voltage corresponding to the feedback current, and the feedback voltage includes a stable voltage value and a voltage change rate;

[0109] When it is determined that the feedback current has a first current value matching the first current interval, before determining that the motor meets the preset normal operating conditions, the method further includes:

[0114] Embodiment 2

[0115] See also Figure 2 , Figure 2 FIG. 1 is a flow chart of another method for detecting the operation of a motor with load disclosed in an embodiment of the present invention. Figure 2 The described method for detecting the operation of a motor with load can be applied to a device for detecting the operation of a motor with load, and the embodiment of the present invention does not limit this. Figure 2 As shown, the method for detecting the operation of a motor with load may include the following operations:

[0116] 201. When a start instruction for a motor is detected, a load detection is performed on the motor according to the start instruction to obtain a load detection result for the motor, where the load detection is used to determine a connection state between a load on the motor and the motor.

[0117] 202. Determine whether the load detection result indicates that the motor meets the preset normal operating conditions.

[0122] 207. When it is determined that the load detection result indicates that the motor does not meet the normal operating conditions, a second operating identifier for the motor is generated, and a second operating control is performed on the motor according to the second operating identifier. The second operating control is used to output an abnormal prompt indicating that the motor has an operating abnormality, and is also used to terminate the power supply to the motor.

[0123] In the embodiment of the present invention, for other descriptions of steps 201 to 203 and step 207, please refer to other specific descriptions of steps 101 to 103 and step 104 in the first embodiment, which will not be repeated in the embodiment of the present invention.

[0124] It can be seen that the implementation Figure 2The described loaded motor operation detection method can collect key parameters such as the motor's speed, temperature and rotation mode in real time during the motor operation, and compare them with preset safety thresholds, thereby realizing continuous monitoring of the motor's operating status. This real-time monitoring mechanism is conducive to improving the speed of discovering abnormal conditions in the motor operation; further, when it is detected that the motor operating parameters meet the preset shutdown conditions, it can automatically generate shutdown supervision information and perform emergency shutdown control on the motor. This intelligent shutdown mechanism can not only effectively avoid damage to the motor due to abnormal conditions such as overheating and overspeed, but also promptly notify relevant personnel for processing, thereby reducing maintenance costs and downtime.

[0125] In an optional embodiment, the above-mentioned method of comparing the operating parameter with the corresponding preset safety threshold execution parameter to obtain the parameter comparison result corresponding to the operating parameter specifically includes:

[0126] When the operating parameters include the motor speed, determining the average speed of the motor in the current recording period according to the operating parameters; and comparing the speed difference between the average speed and a preset speed threshold, and adding the speed difference and the average speed to the parameter comparison result corresponding to the operating parameters;

[0127] When the operating parameters include the motor temperature, determining the heating rate of the motor according to the operating parameters; and comparing the rate difference between the heating rate and a preset heating rate threshold, and adding the rate difference and the heating rate to the parameter comparison result corresponding to the operating parameters;

[0128] When the operating parameters include a motor rotation mode, the intermittent frequency of the motor is determined according to the operating parameters; and the frequency difference between the intermittent frequency and a preset intermittent frequency threshold is compared, and the intermittent frequency and the frequency difference are added to the parameter comparison result corresponding to the operating parameters.

[0129] In this optional embodiment, by making a detailed comparison and analysis of different operating parameters, the operating status of the motor can be evaluated more comprehensively, and the monitoring strategy and control measures can be flexibly adjusted according to actual conditions, thereby enhancing the flexibility and applicability of the system.

[0130] It can be seen that in this optional embodiment, for the motor speed, by calculating the average speed in the current recording period and comparing it with the preset speed threshold, and recording the speed difference and the speed average, it is possible to more accurately reflect the stability and fluctuation of the motor speed, which is beneficial to improve the speed of detecting abnormal speed; for the motor temperature, by calculating the heating rate and comparing it with the preset heating rate threshold, and recording the rate difference and the heating rate, it is possible to more sensitively capture the rapid changes in the motor temperature, and improve the warning speed of potential overheating risks; for the motor rotation mode, by calculating the intermittent frequency and comparing it with the preset intermittent frequency threshold, and recording the intermittent frequency and the frequency difference, it is possible to more accurately evaluate the stability of the motor rotation mode, which is beneficial to improve the speed of identifying abnormal conditions in the intermittent operation of the motor.

[0131] In another optional embodiment, the above-mentioned determination that the operating parameters meet the preset shutdown conditions specifically includes:

[0132] Any operating parameter in the above parameter comparison results does not match the preset safety threshold;

[0133] Among them, when the speed difference indicates that it is greater than the set difference threshold, and / or when the speed difference indicates that it is greater than the set speed threshold, and / or when the intermittent frequency is greater than the set intermittent frequency threshold, it is determined that the operating parameters meet the preset shutdown conditions.

[0134] It can be seen that in this optional embodiment, by real-time monitoring of the motor's speed, temperature and motor rotation mode, the motor operation can be monitored from multiple dimensions, which is beneficial to improving the precision of real-time monitoring of the motor's operation, thereby increasing the speed of detecting motor faults, which in turn is beneficial to increasing the speed of subsequent fault repairs.

[0135] In yet another optional embodiment, the method further comprises:

[0136] When it is determined that the load detection result indicates that the motor meets the normal operating conditions, the component parameters of the load are collected, and the component parameters include the service life of the component and the frequency of component use. The service life of the component includes the production date of the load, the start date of use, and the duration of use;

[0137] Determine target loss information of the load according to the component parameters, the target loss information includes first loss information and second loss information, the first loss information is natural factor-related loss corresponding to the use time; the second loss information includes size change information and shape change information of the load;

[0138] Performing numerical conversion on the target loss information according to a set conversion formula to obtain a target loss rate and / or a target loss value corresponding to the load;

[0139] When it is determined that the target loss rate is greater than or equal to the set usage loss rate, and / or it is determined that the target loss value is greater than or equal to the set usage loss value, it is determined that the load is in an abnormal usage state with abnormal operation; at the same time, a third operation identifier for the load is generated, and a third operation control is performed on the load according to the third operation identifier, the third operation control is used to output an abnormal prompt indicating that the load has excessive loss, and is also used to prompt the user to perform maintenance or replacement operations on the load;

[0140] When it is determined that the target loss rate is less than the set usage loss rate or the target loss value is less than the set usage loss value, it is determined that the load is in a basic state of normal use, and the above-mentioned first operation control of the motor according to the first operation identifier is triggered to control the corresponding operation of the motor rotation.

[0141] It can be seen that in this optional embodiment, in addition to setting up an operation monitoring scheme for the motor and the load, especially the motor, a wear detection scheme for the load is also set up. On the basis that the motor meets normal operating conditions, the wear monitoring of the load can be further realized, thereby improving the detection speed and processing speed of abnormal wear of the load, reducing the situation of motor failure caused by normal motor and abnormal load (excessive wear of components), and further improving the safety and reliability of the products corresponding to the motor and the load.

[0143] See also Figure 3 , Figure 3 : is a schematic diagram of the structure of a motor operation detection device with load disclosed in an embodiment of the present invention. The motor operation detection device with load can be a motor operation detection terminal, device, system or server with load. The server can be a local server, a remote server, or a cloud server (also known as a cloud server). When the server is a non-cloud server, the non-cloud server can communicate with the cloud server, which is not limited in the embodiment of the present invention. Figure 3 As shown, the motor operation detection device with load may include a load detection module 301, a judgment module 302, a first operation control module 303 and a second operation control module 304, wherein:

[0144] The load detection module 301 is used to perform load detection on the motor according to the start instruction when a start instruction for the motor is detected to obtain a load detection result for the motor. The load detection is used to determine the connection status of the load on the motor and the motor.

[0145] The judgment module 302 is used to judge whether the load detection result indicates that the motor meets the preset normal operating conditions.

[0146] The first operation control module 303 is used to generate a first operation identifier for the motor when the judgment module 302 judges that the load detection result indicates that the motor meets the normal operation conditions, and perform a first operation control on the motor according to the first operation identifier to control the rotation of the motor.

[0147] The second operation control module 304 is used to generate a second operation identifier for the motor when the judgment module 302 determines that the load detection result indicates that the motor does not meet the normal operating conditions, and perform a second operation control on the motor according to the second operation identifier. The second operation control is used to output an abnormal prompt indicating that the motor has an operating abnormality, and is also used to terminate the power supply to the motor.

[0148] It can be seen that the implementation Figure 3 The described loaded motor operation detection device, upon receiving a start-up command for the motor, immediately performs load detection, thereby ensuring instant confirmation of the connection status between the motor and the load before starting, effectively avoiding motor failure or abnormal operation due to improper load connection, thereby facilitating improving the real-time and accuracy of motor operation monitoring; further, according to different load detection results, it can intelligently generate a first operation identification or a second operation identification for the motor, and execute an adapted first or second operation control, that is, through the load detection, it can discover and deal with potential problems before the motor runs in advance, such as poor load connection, thereby effectively preventing possible failures of the motor during operation; at the same time, when the motor runs abnormally, it can quickly locate the problem and take corresponding measures, such as outputting abnormal prompts and terminating power supply, which provides convenience for subsequent fault diagnosis and repair, and helps reduce maintenance costs.

[0149] In an optional embodiment, the load detection module 301 performs load detection on the motor according to the start instruction, and the manner of obtaining the load detection result for the motor specifically includes:

[0150] Calling a running detection program for the motor according to the start command, and generating a test voltage for the motor according to the running detection program; the test voltage is used to control the preset test time of the motor start;

[0152] The feedback current, the preset test time, and the test voltage are determined as the load detection result for the motor.

[0153] It can be seen that in this optional embodiment, the detection program set up can ensure that the motor can perform load detection under safe conditions, avoiding the risks that may be caused by direct startup; at the same time, multi-dimensional test parameters can be integrated as the load detection results of the motor, which is beneficial to improve the accuracy and reliability of determining the corresponding load detection results of the motor.

[0154] In another optional embodiment, the determination module 302 determines whether the load detection result indicates that the motor meets the preset normal operating conditions in the following manner:

[0155] Obtaining rated current information recorded for the motor; the rated current information includes a first current interval and a second current interval, the first current interval being a correspondingly recorded power-on current interval when the motor is normally connected to the load; the second current interval being a correspondingly recorded power-on current interval when the motor is unloaded;

[0156] Determining whether the feedback current has a first current value that matches the first current interval; when it is determined that the feedback current has a first current value that matches the first current interval, determining that the motor meets a preset normal operating condition;

[0157] When it is determined that the feedback current does not have a first current value that matches the first current interval, it is determined whether the feedback current has a second current value that matches the second current interval, and when it is determined that the feedback current has a second current value that matches the second current interval, it is determined that the motor meets a preset first abnormal condition;

[0158] When it is determined that the feedback current does not have a second current value matching the second current interval, it is determined that the motor meets a preset second abnormal condition.

[0159] In this optional embodiment, the connection state includes a first state indicating that the load is normally connected to the motor or a second state opposite to the first state, and the second state includes a first sub-state or a second sub-state; the first sub-state is used to indicate that the motor is not connected to the load; the second sub-state is used to indicate that the motor is connected to the load and the load has an operating fault, and / or, is used to indicate that there is an abnormality in the connection path between the motor and the load;

[0160] When the motor meets normal operating conditions, the load and the motor are in a first state;

[0161] When the motor meets the first abnormal condition, the load and the motor are in the first sub-state; when the motor meets the second abnormal condition, the load and the motor are in the second sub-state.

[0162] It can be seen that in this optional embodiment, by judging whether the feedback current falls into these intervals, different operating states of the motor can be accurately distinguished, including normal operation, load not connected (first abnormal condition) and connection abnormality or load failure (second abnormal condition), thereby improving the accuracy of judging the connection state between the motor and the load; further, the connection state can be subdivided into a first state indicating that the load is normally connected to the motor, a first sub-state indicating that the load is not connected, and a second sub-state indicating that the connection is abnormal or the load is faulty. This detailed classification method is conducive to improving the accuracy of identifying the operating state of the motor.

[0163] In yet another optional embodiment, the test parameter further includes a feedback voltage corresponding to the feedback current, and the feedback voltage includes a stable voltage value and a voltage change rate;

[0164] The method in which the judging module 302 judges whether the load detection result indicates that the motor meets the preset normal operating conditions specifically includes:

[0166] When the current comparison result indicates that the current change rate is consistent with the rated current change rate, and the voltage change rate is consistent with the rated voltage change rate, the above-mentioned determination that the motor meets the preset normal operating conditions is triggered.

[0167] It can be seen that in this optional embodiment, by simultaneously monitoring the feedback current and the feedback voltage and comparing their change rates with the rated values, the actual operating state of the motor can be more comprehensively reflected; at the same time, this dual monitoring mechanism makes the judgment of the motor operating state more complete and reliable.

[0168] In another alternative embodiment, see Figure 4 , Figure 4 Schematic diagram of a structure of a motor operation detection device with load disclosed in an embodiment of the present invention. Figure 4 As shown, the device also includes a parameter acquisition module 305, a parameter comparison module 306 and a shutdown control module 307, wherein:

[0169] The parameter acquisition module 305 is used to acquire the operation parameters of the motor after the first operation control module 303 performs the first operation control on the motor according to the first operation identifier, and the operation parameters include at least one parameter of the motor speed, the motor temperature and the motor rotation mode;

[0170] A parameter comparison module 306 is used to compare the operating parameter with the preset safety threshold execution parameter corresponding to the operating parameter to obtain a parameter comparison result corresponding to the operating parameter;

[0172] It can be seen that in this optional embodiment, during the operation of the motor, key parameters such as the motor's speed, temperature and rotation mode can be collected in real time and compared with the preset safety thresholds, thereby realizing continuous monitoring of the motor's operating status. This real-time monitoring mechanism is beneficial to improving the speed of discovering abnormal conditions in the operation of the motor; further, when it is detected that the motor operating parameters meet the preset shutdown conditions, shutdown supervision information can be automatically generated, and emergency shutdown control can be performed on the motor. This intelligent shutdown mechanism can not only effectively avoid damage to the motor due to abnormal conditions such as overheating and overspeeding, but also promptly notify relevant personnel for processing, thereby reducing maintenance costs and downtime.

[0173] In another optional embodiment, the parameter comparison module 306 compares the operating parameter with the corresponding preset safety threshold execution parameter, and obtains the parameter comparison result corresponding to the operating parameter in a manner specifically including:
