[0044] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0045] In order to illustrate the technical solution described in this application, specific embodiments are provided below.

[0046] As people's material living standards improve, their pursuit of spiritual life is also increasing. Raising pets can enrich people's spiritual life and bring them happiness and companionship. Therefore, raising pets has become the choice of more and more people, and the convenience of feeding has become a concern for people when raising pets.

[0047] Typically, pets are fed a single serving of food, which is a portion of food delivered to the pet at each meal. This method requires manual feeding at each meal, which is cumbersome. Furthermore, it is difficult to separate wet and dry food during feeding, hindering accurate feeding control.

[0048] Based on this, an embodiment of the present application proposes a pet feeder. FIG1 is a schematic structural diagram of a pet feeder provided by an embodiment of the present application. As shown in FIG1 , the pet feeder includes a turntable 10, a drive motor 20, a shielding component 30, and a control module 40. Specifically, more than two food troughs 101 can be provided on the turntable 10, and the food troughs 101 can be divided according to the angle of the turntable 10. For example, when there are five food troughs 101 on the turntable 10, the food troughs can be respectively provided in the ranges of 0-72 degrees, 72-144 degrees, 144-216 degrees, 216-288 degrees, and 288-360 degrees in the turntable.

[0049] The shielding portion 30 is used to shield a portion of the food trough 101 in the turntable 10, temporarily preventing the pet from eating the food in the food trough 101. The food trough 101 that is not shielded can be used for the pet to eat. In general, the number of unshielded food troughs 101 can be one or two.

[0050] The drive motor 20 is used to drive the turntable 10 to rotate. The drive motor 20 can be a stepper motor or a DC motor. The drive motor 20 can receive a control signal from the control module 40 to drive the turntable to rotate to a desired rotation angle, thereby facilitating the control of the states of different food troughs 101 at different times. In the timing control process, the time for controlling the rotation of the turntable can be determined by a crystal oscillator and a real-time clock (RTC in English). The control module 40 is responsible for the control of the entire pet feeder, as well as the signal processing and logical judgment of the feedback, and the logic output. The control module 40 includes but is not limited to a microcontroller (MCU), a central processing unit (SOC), a logic circuit, etc.

[0051] FIG2 is a schematic diagram of a process flow for implementing a control method for a pet feeder according to an embodiment of the present application, which is described in detail as follows:

[0052] In S201, a preset feeding plan is obtained, where the feeding plan includes a correspondence between food types and feeding times.

[0053] The feeding plan in the embodiment of the present application can include the types of food that need to be fed, and the feeding times of different types of food. For example, when the types of food that need to be fed include A, B, and C, it can be set to feed Class A food in the morning, Class B food at noon, and Class C food in the evening. Or, at the same time, when the number of food troughs in the turntable that are not blocked is 2 (such as two adjacent food troughs), the feeding plan can be set to a combination of different foods at the same time, including a combination of dry and wet foods. For example, the feeding plan can include feeding Class A food and Class B food in the morning, feeding Class A food and Class C food at noon, and feeding Class B food and Class C food in the evening. Since different foods are in different food troughs, the dry and wet separation of pet food can be effectively achieved.

[0054] In the feeding plan of the present application, the correspondence between food troughs and feeding times can be pre-set. For example, if the turntable includes N food troughs, and the number of food troughs in a feedable state (unblocked) at any one time is 1, then the correspondence between food types and feeding times can be determined by placing the food items in the food troughs in order.

[0055] In one possible implementation, the pet feeder can communicate with a smart terminal, allowing the smart terminal to set the mapping between food types and feeding times. For example, after a user places food in a food trough, the user can use the smart terminal to select the mapping between each food trough and the food type, and set the mapping between different food types and feeding times. Once the smart terminal completes the settings, the configured feeding plan can be sent to the pet feeder. Alternatively, the user can set the feeding plan using the pet feeder's setting buttons and prompts on the display.

[0056] In order to facilitate setting the corresponding relationship between the food types and the food troughs in the feeding plan, food trough identifiers can be set on the food troughs, and the positions of the food troughs can be determined according to the food trough identifiers. For example, the food trough identifiers can include digital identifiers.

[0057] In S202, the corresponding relationship between the rotation angle of the turntable and the feeding time is determined according to the feeding plan and in combination with the pre-set corresponding relationship between the food types and the rotation angles.

[0058] The types of food in the embodiment of the present application can be set in the food troughs in the turntable in sequence according to the order of feeding time. In this case, combined with the correspondence between the food types and the rotation angles, the correspondence between the determined rotation angles and the feeding times, as time goes by, it is only necessary to rotate the predetermined angle at the set time to switch the turntable to the next food trough for feeding, which can improve the convenience of feeding control.

[0059] For example, in the turntable schematic diagram shown in FIG3 , the turntable includes 6 food troughs, the feeding plan includes six types of food, A, B, C, D, E, and F, and the feeding order of the feeding plan is A, B, C, D, E, and F. Then, according to the feeding order, A, B, C, D, E, and F can be placed in food troughs 1, 2, 3, 4, 5, and 6 in sequence. The determined corresponding relationship between the rotation angle and the feeding time can be: the first moment corresponds to a rotation angle of 0 degrees, the second moment corresponds to a rotation angle of 60 degrees, the third moment corresponds to a rotation angle of 120 degrees, the fourth moment corresponds to a rotation angle of 180 degrees, the fifth moment corresponds to a rotation angle of 240 degrees, and the sixth moment corresponds to a rotation angle of 300 degrees. Among them, the first moment to the sixth moment are different sequential feeding times.

[0060] In a possible implementation, the correspondence between the food types in the food trough and the rotation angle (the correspondence between the food types and the rotation angle is the angle at which the turntable rotates from the initial state to the state at which the food type is feedable. The same food type can be placed in multiple food troughs and can correspond to multiple rotation angles) can be arbitrarily configured, and the correspondence between the food types and the feeding time in the feeding plan can also be arbitrarily configured. For example, the food types include two types, A and B, and the feeding plan is to feed types A and B alternately. In a turntable including N food troughs, the food troughs where type A food is located can be set to be the 1st to |N / 2|th food troughs configured with type A food, and the |N / 2|+1th food trough to the Nth food trough are configured with type B food. Alternatively, type A food and type B food can also be alternately arranged in the food troughs.

[0061] In S203, the turntable is controlled to rotate according to the corresponding relationship between the rotation angle of the turntable and the feeding time, so that the turntable rotates until the food slot of the food type corresponding to the feeding time is in an unblocked state.

[0062] After determining the correspondence between the turntable's rotation angle and the feeding time, when the corresponding feeding time arrives, control the turntable to the corresponding rotation angle. The turntable's rotation angle is the angle the turntable needs to rotate to reach the target position from the initial state. When determining the required rotation amplitude at the current time, the required rotation amplitude can be determined based on the position before rotation and the target position corresponding to the rotation angle. For example, if the position before rotation is 180 degrees and the target position corresponding to the rotation angle is 300 degrees, then the rotation amplitude is 300-180=120 degrees. You only need to rotate 120 degrees in the predetermined rotation direction based on the current position to make the target food trough in a feedable state.

[0063] In the embodiment of the present application, in addition to pre-setting a feeding plan for feeding, feeding instructions can also be received for feeding.

[0064] For example, the feeding instruction may be a feeding instruction including specific types of food. For example, the types of food include A, B, and C types of food. When a feeding instruction for type A food is received, the turntable can be controlled to rotate so that the food trough containing type A food is in a feedable state. When the same type of food is contained in more than two food troughs, a selection can be made based on the number of times the food trough is opened (or the number of times it is in a feedable state) and the size of the food trough. For example, when it is detected that the number of times a food trough is in a feedable state reaches a predetermined number, the food in the food trough may have been consumed, and the next food trough containing the same type of food can be controlled to be in a feedable state by rotation. Alternatively, the amount of food remaining in the food trough can be determined by weight detection or other methods. When the amount of food remaining in the food trough is less than a predetermined food amount threshold, the turntable is controlled to rotate until the next food trough containing the same type of food is in a feedable state.

[0065] During the operation of the pet feeder, food residue or other objects may clog the turntable, causing it to be stuck. In order to promptly detect whether the turntable is abnormal, the abnormal state screening during the rotation process and the abnormal state screening based on the duration can be used to determine whether the turntable is abnormal.

[0066] As shown in Figure 4, abnormal status screening of the rotation process may include:

[0067] In S401, the operating current of the driving motor is detected while the rotation of the turntable is controlled according to the corresponding relationship between the rotation angle of the turntable and the feeding time.

[0068] Based on the corresponding relationship between feeding time and rotation angle, the turntable is controlled to rotate when the set time is reached. At this time, the operating current of the drive motor can be sampled according to the pre-set sampling time. The operating current can be sampled using a current sensor such as a Dürer sensor.

[0069] In S402 , if, within a predetermined detection period, the operating current exceeding a predetermined proportion is greater than a predetermined current threshold, it is determined that the turntable is in a stalled state.

[0070] The sampled current can be converted into a digital current signal through analog-to-digital conversion, and the current of the digital signal can be compared with a predetermined current threshold to determine whether the sampled current is greater than the current threshold. Alternatively, the analog current signal can be directly compared with a comparator to determine whether the sampled current is greater than the current threshold.

[0071] The detection period can be shorter than the time it takes for the turntable to complete a single rotation. By monitoring the operating current (i.e., the current required to drive the motor) during the turntable's rotation, if a predetermined proportion of the detected current exceeds a current threshold within a predetermined period, the turntable is determined to be in a stalled state. Since a predetermined proportion of the sampled values ​​within the detection period are all greater than the current threshold, the impact of interference signals on the detection results can be effectively reduced, improving detection accuracy.

[0072] In a possible implementation, abnormal states can be filtered based on duration to determine whether the turntable is in an abnormal state of stalling. For example, based on the correspondence between rotation angle and feeding time, the turntable can be controlled to rotate after a predetermined time has elapsed. Within a predetermined period of time after the turntable begins rotating or after a control command is issued, the turntable is checked to determine whether it has reached the target position corresponding to the feeding time.

[0073] The predetermined duration may be greater than the duration required for the turntable to complete a single rotation under standard conditions. For example, if the duration for completing a single rotation under standard conditions is 2-3 seconds, the predetermined duration may be 5 seconds, 7 seconds, or the like.

[0074] When detecting whether the turntable has rotated to the target position, the real-time angle of the turntable can be determined by using infrared sensors, duplex sensors, ultrasonic sensors or encoders, and the real-time angle of the turntable is compared with the angle of the target position to determine whether the turntable has completed the rotation task.

[0075] When the rotation process screening or the time length screening determines that the turntable is in a stalled state, a stall prompt may be output, or the stall may be eliminated according to a predetermined stall elimination method.

[0076] The method for eliminating stalling may be as shown in FIG5 , including:

[0077] In S501 , a stall elimination instruction is generated at a predetermined time interval.

[0078] When it is determined that the turntable is in a stalled state, stall elimination processing can be performed at predetermined time intervals, that is, stall elimination instructions are periodically generated to eliminate the stall, thereby reducing the probability of damage to the motor or other equipment due to continued stalling.

[0079] In S502, according to the stall elimination instruction, the turntable is controlled to rotate toward the target rotation angle in a predetermined rotation direction, or is controlled to rotate toward the target rotation angle in a direction opposite to the predetermined rotation direction, or is controlled to move back a predetermined angle and then rotate toward the target rotation angle.

[0080] When a stall is eliminated according to a stall elimination instruction, the stall can be eliminated by switching the rotation direction. For example, before the stall occurs, the turntable rotates in a first direction (clockwise or counterclockwise). When the turntable is detected to be in a stalled state, the turntable is controlled to rotate in a second direction (opposite to the first direction) to try to eliminate the stall.

[0081] Alternatively, the system may rotate toward the target rotation angle of the current rotation task according to the stall elimination instruction at a predetermined time interval, and determine whether the stall state can be eliminated by making several attempts at a predetermined time interval.

[0082] Alternatively, the motor can be controlled to rotate in a first direction by a predetermined angle and then in a second direction. The second direction can be the direction that completes the current rotation task, and the first and second directions are parallel. The stalled state can be eliminated by backing off and trying again.

[0083] When the number of attempts reaches a predetermined threshold and the jam still cannot be eliminated, a prompt message indicating that the jam elimination attempt failed may be generated, for example, a prompt message may be sent to a bound smart terminal.

[0084] During the use of the pet feeder, the angle of the turntable may deviate due to improper use by the pet or other reasons. In order to improve the reliability of the pet feeder, a process of resetting the turntable may be included, as shown in Figure 6. The process includes:

[0085] In S601, the position and posture of the turntable is detected according to a predetermined detection period.

[0086] The predetermined detection period can be determined based on the usage time of the pet feeder and the frequency of malfunctions. For example, the longer the pet feeder is used, the shorter the detection period can be. The more frequently the turntable position anomalies occur, the shorter the detection period can be.

[0087] The position of the turntable can be expressed as the rotation angle of the turntable, which can be detected by any one of an infrared sensor, a Hall sensor, an ultrasonic sensor, or an encoder.

[0088] In S602 , a deviation between the detected posture and the standard posture is determined, where the deviation includes a deviation angle and a deviation direction.

[0089] Based on the corresponding relationship between feeding time and rotation angle, combined with the feeding time determined at the current time, the standard position of the turntable, that is, the standard rotation angle, can be obtained. The deviation between the detected position and the standard position can be expressed as the deviation between the standard rotation angle and the current rotation angle.

[0090] For example, based on the corresponding relationship between feeding time and rotation angle, if the current rotation angle is 270 degrees and the actual rotation angle is 280 degrees, the deviation is 10 degrees. If the rotation direction is set to counterclockwise, the turntable can be controlled to rotate 10 degrees in the same direction or 350 degrees clockwise.

[0091] In S603, the turntable is controlled to reset according to the deviation angle and the deviation direction.

[0092] After determining the deviation between the standard posture and the detection posture, the turntable can be controlled to rotate and return to the standard posture.

[0093] Figure 7 shows a schematic diagram of the turntable's deviation reset. The reset direction can be set to a predetermined direction, such as counterclockwise. As shown in the upper portion of Figure 7, when the turntable deviates counterclockwise, it can be rotated a larger angle counterclockwise to return to its standard position. As shown in the lower portion of Figure 7, when the turntable deviates clockwise, it can be rotated a smaller angle counterclockwise to return to its standard position.

[0094] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
