[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The following describes a method for detecting a state of a lifting mechanism, a computer-readable storage medium, an air-conditioning controller, and an air-conditioner according to an embodiment of the present invention with reference to the accompanying drawings.

[0036] Figure 1 Flow chart of a method for detecting a state of a lifting mechanism according to an embodiment of the present invention.

[0037] In one embodiment of the present invention, the state detection method of the lifting mechanism is applied to the air conditioner 1000, referring to Figure 2As shown, the lifting mechanism includes a driving motor 1, a traction member 2 and a bearing part 3. The traction member 1 drives the bearing part 3 to move up and down under the drive of the driving motor 1. When the bearing part 3 rises to the target position, it provides humidification water to the air conditioner 1000.

[0038] Specifically, the traction member 2 can be a traction rope, and the bearing part 3 can be a chassis that can prevent the water tank. At this time, one end of the traction rope is connected to the bearing part 3, and the other end is connected to the winding mechanism converted by the driving motor 1. When the driving motor 1 works clockwise, it drives the winding mechanism to work clockwise, so that the traction rope that is not wound on the winding mechanism is gradually wound on the winding mechanism, and the traction rope is recovered. The bearing part 3 rises with the recovery of the traction rope. When the driving motor 1 works counterclockwise, it drives the winding mechanism to work counterclockwise, so that the traction rope wound on the winding mechanism is gradually released, and the bearing part 3 is lowered under the action of gravity. In order to ensure the stability of the bearing part 3 during the rising / falling process, the lifting mechanism is also equipped with a telescopic mechanism 4, one end of the telescopic mechanism 4 is connected to the bearing part 3, and the other end can be connected to the air conditioner 1000. The telescopic mechanism 4 is scaled as the bearing part 3 rises and falls. Thus, the humidification and water replenishment action of the air conditioner hanging machine can be realized through the lifting mechanism.

[0039] Specifically, when the lifting mechanism performs the ascending process, the driving motor 1 is controlled to work clockwise to store the traction member 2 to perform the traction member 2 recovery action. The traction member 2 pulls the load-bearing part 3 to rise, and the telescopic mechanism 4 shrinks upward as the load-bearing part 3 rises. Its main function is to stabilize the load-bearing part 3 and prevent the load-bearing part 3 from shaking during the ascending process. When the load-bearing part 3 is pulled up to the highest point, that is, the target position, the driving motor 1 stops rotating, the ascending process is completed, and the air conditioner can perform the humidification function through the water in the load-bearing part 3.

[0040] When the lifting mechanism is in the process of descending, the driving motor 1 is controlled to reverse, that is, work counterclockwise, to lower the traction member 2, the carrying part 3 is lowered, and the telescopic mechanism 4 is lowered as the carrying part 3 descends. When the carrying part 3 descends to the lowest point, the driving motor 1 is controlled to stop rotating, and the descending process is completed. At this time, the user can take out the water tank in the carrying part 3, perform water filling operation on the water tank, and put the water tank filled with water back into the carrying part 3, and control the lifting mechanism to perform the ascending process, so that the carrying part 3 rises to the target position to provide humidification water for the air conditioner 1000.

[0041] Furthermore, the lifting mechanism can determine the current position of the bearing part 3 through a limit switch or according to parameters such as the rotation time of the driving motor and the number of motor feedback pulses, thereby controlling the driving motor 1. Figure 3 The lifting mechanism is in the stored state, that is, when it rises to the target position. At this time, the supporting part 3 rises to the target position, and the lifting mechanism is stored inside the air conditioner 1000.

[0042] Although the above-mentioned lifting mechanism solves the humidification and water replenishment work of the air conditioner, the operating status of the lifting mechanism is difficult to monitor. In order to further improve the working quality of the lifting mechanism, the present application proposes a state detection method of the lifting mechanism.

[0043] like Figure 1 As shown, the state detection method of the lifting mechanism includes: determining the tension change information of the traction member; and determining the state information of the lifting mechanism according to the tension change information of the traction member.

[0044] Specifically, during the process of the lifting mechanism ascending or descending, or when the lifting mechanism is in the storage state, the tension of the traction member is monitored in real time to determine the tension change information of the traction member, and the state of the lifting mechanism is judged according to the tension change information of the traction member. The tension change information can be the tension fluctuation value of the traction member during the process of the lifting mechanism ascending or descending, or the difference between the tension and the initial tension, or the tension change value of the lifting mechanism in the storage state. In addition, the tension change information should include the tension change direction and the tension change value. The tension increase or decrease is determined according to the tension change direction, and the tension fluctuation amplitude is determined according to the tension change value.

[0045] For example, when the lifting mechanism is ascending or descending, if the pulling force of the traction member suddenly increases or decreases according to the pulling force of the traction member, it is considered that the lifting mechanism has encountered an obstacle, for example, the load-bearing part hits a person passing below during the descent. When the lifting mechanism is in the storage state, it is determined that the pulling force of the traction member decreases to the minimum pulling force value, then it is considered that the current load-bearing part is in a water shortage state, and the amount of water inside the load-bearing part cannot meet the humidification demand of the air conditioner. For another example, when the lifting mechanism descends to the lowest point, it can also be judged based on the pulling force change information of the traction member to determine whether the lifting mechanism has completed the water replenishment action.

[0046] In addition, Figure 2 , Figure 4 For example, the lifting mechanism is further provided with an auxiliary pulley 5 and a pressure sensor 6. The auxiliary pulley 5 and the pressure sensor 6 cause the traction member 2 to be misaligned, so that when the traction member 2 pulls the bearing portion 3, it will generate pressure on the pressure sensor 6, wherein the direction of the force is Figure 4 The pressure sensor 6 determines whether the load carried by the traction member 2 has changed by detecting the pressure value and outputs a corresponding pressure signal. Figure 5As shown, the pressure sensor 6 has a Wheatstone bridge inside. When the pressure sensor 6 is subjected to pressure, the Wheatstone bridge will output a pressure difference, which is proportional to the pressure. After being amplified by the operational amplifier, the voltage signal is output to the MCU (Micro Controller Unit). The MCU establishes a proportional relationship between the voltage signal and the pressure value to calculate the pressure value borne by the pressure sensor 6, thereby determining the tension of the traction member 2, and then determining the tension change information of the traction member 2 based on the voltage signal obtained over a period of time.

[0047] In one embodiment of the present invention, determining the state information of the lifting mechanism according to the tension change information of the traction member includes: determining the tension fluctuation value of the traction member according to the tension change information of the traction member; and determining that the bearing part is shaking when the absolute value of the tension fluctuation value of the traction member exceeds a first preset threshold value. The first preset threshold value can be set according to actual conditions.

[0048] Specifically, when the lifting mechanism is ascending or descending, if the load-bearing part ascends or descends too fast, or the center of gravity is unbalanced, it will shake left and right, and this shaking will act on the traction member, making its pulling force unstable and causing the pulling force to fluctuate. Figure 4 Taking the pressure sensor 6 as an example, the real-time detection of the pulling force of the traction member 2 is performed. As the pulling force of the traction member 2 fluctuates, the pressure value detected by the pressure sensor 6 is also unstable. When the bearing part 3 shakes, the pressure value detected by the pressure sensor 6 will fluctuate greatly within a preset period (e.g., 50ms).

[0049] For example, when the pressure value detected by the pressure sensor changes within a preset period and exceeds a preset pressure threshold, it is considered that the absolute value of the tension fluctuation value of the traction member exceeds the first preset threshold, and it is determined that the load-bearing portion is shaking. Assume that the current pressure value detected by the pressure sensor is P, and the pressure value 0.5 seconds ago is P1, and the preset pressure threshold is P_off1, for example, P_off1 is 0.05kg. Then when the lifting mechanism performs an ascending or descending process, if P-P1>P_off1 or P1-P>P_off1, it is considered that the absolute value of the tension fluctuation value of the traction member exceeds the first preset threshold, and the load-bearing portion is shaking.

[0050] It should be noted that, in addition to the above-mentioned technical solution, the pressure value detected by the pressure sensor is used to directly judge whether the absolute value of the tension fluctuation value of the traction member exceeds the first preset threshold value. The pressure value detected by the pressure sensor can also be first converted into the tension of the traction member, and then the tension fluctuation value is judged whether it exceeds the first preset threshold value based on the tension of the traction member obtained by the conversion. There is no limitation here.

[0051] In one embodiment of the present invention, when it is determined that the load-bearing portion is shaking, the state detection method of the lifting mechanism further includes: controlling the driving motor to reduce speed to stabilize the load-bearing portion.

[0052] That is, when it is determined that the load-bearing part is shaking during the ascent or descent process, the speed of the drive motor is controlled to reduce the preset speed threshold, and the operation is continued at the adjusted speed, so that the load-bearing part is stabilized. In addition, when the drive motor is controlled to continue the ascent or descent process at the adjusted speed, the tension of the traction member is re-acquired, the tension fluctuation value is determined, and the state of the lifting mechanism is further judged according to the re-determined tension fluctuation value. If it is determined that the load-bearing part is still shaking according to the re-acquired tension fluctuation value of the traction member, the speed reduction adjustment is continued to be performed to further stabilize the load-bearing part.

[0053] In one embodiment of the present invention, during the process of controlling the driving motor to decelerate, the state detection method of the lifting mechanism further includes: determining the number of deceleration adjustments of the driving motor; and determining that a mechanical failure of the lifting mechanism occurs when the number of deceleration adjustments reaches a preset number threshold. The preset number threshold can be set according to actual conditions.

[0054] That is to say, if the load-bearing part is still in a shaking state after the drive motor is decelerated for a preset number of times, it is determined that a mechanical failure has occurred in the lifting mechanism, such as a motor bearing failure, and the drive motor is controlled to stop running and an alarm is issued.

[0055] For example, when the lifting mechanism is performing an ascending process, if it is determined that the load-bearing part is shaking based on the tension fluctuation value of the traction member, the drive motor is decelerated, and the tension change information of the traction member is acquired again, and the state information of the lifting mechanism is judged based on the reacquired tension change information. If it is determined that the load-bearing part is still shaking based on the reacquired tension fluctuation information of the traction member, the above steps are repeated to decelerate the drive motor; if it is determined that the load-bearing part is not shaking based on the reacquired tension fluctuation information of the traction member, the drive motor is controlled to continue the ascending process at the current speed. If the number of deceleration adjustments of the drive motor during the ascending process reaches a preset number threshold, it is considered that a mechanical failure has occurred in the lifting mechanism, and the purpose of stabilizing the load-bearing part cannot be achieved by deceleration adjustment, the drive motor is controlled to stop, and an alarm is issued to promptly remind the user to check and repair the lifting mechanism.

[0056] In one embodiment of the present invention, determining the state information of the lifting mechanism according to the tension change information of the traction member further includes: determining the initial tension of the traction member and the current tension of the traction member according to the tension change information of the traction member; and determining that the bearing part encounters an obstacle when the absolute value of the tension difference between the initial tension and the current tension reaches a second preset threshold. The second preset threshold can be set according to actual conditions.

[0057] Specifically, taking the second preset threshold of 0.5kg as an example, assuming that when the load-bearing part needs to be controlled to descend for water replenishment, the initial tension of the traction member is determined to be 2kg, and the drive motor is controlled to rotate counterclockwise to control the load-bearing part to descend. During the descent of the load-bearing part, the real-time tension of the traction member is detected. When the load-bearing part hits an obstacle, such as the bottom of the load-bearing part hitting a person or moved furniture below, the tension of the traction member will be reduced. Therefore, the current tension of the traction rope is compared with the initial tension. If the absolute value of the tension difference between the initial tension and the current tension reaches 0.5kg, it is confirmed that the load-bearing part has encountered an obstacle.

[0058] It should be noted that through Figure 4 Taking the example of obtaining the tension of the traction member using the pressure value obtained in real time by the pressure sensor shown, the tension value obtained in real time by the pressure sensor can be directly used to determine whether the load-bearing part encounters an obstacle. Alternatively, the tension of the traction member can be obtained by converting the pressure value obtained in real time by the pressure sensor, and then determining whether the load-bearing part encounters an obstacle based on the tension value of the traction member. There is no limitation here.

[0059] In one embodiment of the present invention, when it is determined that the carrying part encounters an obstacle, the state detection method of the lifting mechanism further includes: controlling the driving motor to stop running.

[0060] That is to say, when it is determined that the bearing part encounters an obstacle, the driving motor is controlled to stop working and an alarm is issued to avoid damage to the device or injury to personnel due to continued operation.

[0061] In addition, after determining that the obstacle has been removed, the drive motor can be controlled to continue to perform the corresponding control work. Whether the above-mentioned obstacle has been removed can be determined manually or based on the change in the tension of the traction member. For example, after the drive motor stops, the control unit continues to judge the tension of the traction member according to the pressure information output by the pressure sensor. When it is determined that the absolute value of the tension difference between the initial tension and the current tension is less than the third preset threshold, it is considered that the obstacle of the load-bearing part has been removed. Then, after the first preset time, the control unit continues to control the drive motor to perform the work according to the preset program to ensure the normal progress of the work, while reducing manual participation and improving the user experience.

[0062] In one embodiment of the present invention, determining the state information of the lifting mechanism according to the pulling force change information of the traction member further includes: determining the amount of water remaining in the load-bearing part according to the pulling force change information of the traction member; and determining that the load-bearing part is in a water shortage state when the amount of water remaining drops to a preset water volume threshold. The preset water volume threshold can be set according to actual conditions.

[0063] Specifically, when the load-bearing part of the lifting mechanism rises to the target position, humidification water is provided to the air conditioner. When the air conditioner uses the water in the load-bearing part for cleaning or humidification during operation, the water in the load-bearing part will decrease, and the pulling force of the traction member will also decrease. When it is determined that the pulling force of the traction member is reduced to the minimum pulling force threshold, it is determined that the remaining water in the load-bearing part has dropped to the preset water amount threshold, and it is considered that the load-bearing part is in a water shortage state, and a water shortage prompt is issued to prompt the user to add water. The above-mentioned minimum pulling force threshold can be preset according to actual conditions, for example, it can be set according to the weight of the load-bearing part without water, and it can also be determined according to the traction force increased by the water injection action.

[0064] In addition, the lifting mechanism can also determine the amount of water injected into the load-bearing part according to the tension change information of the traction member determined during the descent process and the ascent process. For example, when the load-bearing part descends to the lowest point, the tension P_L of the current traction member is obtained. When the lifting mechanism receives the ascent command, the tension P of the current traction member is obtained, thereby determining the additional tension P_w=P-P_L. The weight of the injected water can be calculated based on the tension P_w, and the volume of the water can be calculated in combination with the density of the water, thereby determining whether the lifting mechanism has completed the preset water injection process and whether the amount of water injected has reached the standard. It is understandable that after the load-bearing part descends to the lowest point, the user takes out the water tank in the load-bearing part to complete the water injection action, and puts the water tank that has completed the water injection back into the load-bearing part, and then performs the ascent process. Therefore, the amount of water injected can be determined based on the tension obtained at the lowest point and the initial tension of the ascent process.

[0065] The state detection method of the lifting mechanism can determine whether the lifting mechanism shakes left and right or encounters an obstacle during the lifting process based on the tension change information of the traction rope, and when it is determined that the load-bearing part of the lifting mechanism shakes left and right, the driving motor is controlled to slow down to achieve stability, and the brake is applied in time when it is determined that an obstacle is encountered. In addition, the water volume in the load-bearing part can also be detected based on the tension change information of the traction rope, so as to notify the user to replenish water in time.

[0066] As a specific embodiment of the present application, Figure 6 As shown, in the process of controlling the lifting mechanism to perform ascending or descending, the state detection method of the lifting mechanism may include the following steps:

[0067] S601, controlling the lifting mechanism to perform an ascending / descending action.

[0081] In summary, according to the state detection method of the lifting mechanism of the embodiment of the present invention, the state detection method of the lifting mechanism is applied to the air conditioner, the lifting mechanism includes a driving motor, a traction member and a bearing part, the traction member drives the bearing part to move up and down under the drive of the driving motor, and when the bearing part rises to the target position, it provides humidification water to the air conditioner, and the state detection method determines the tension change information of the traction member, and determines the state information of the lifting mechanism according to the tension change information of the traction member. Therefore, the method realizes the supplement of the air conditioner humidification water based on the lifting mechanism, and judges the state information of the lifting mechanism according to the tension change information of the traction member, thereby realizing real-time monitoring of the lifting mechanism, ensuring the operation stability of the lifting mechanism, and providing guarantee for the humidification water of the air conditioner.

[0082] Corresponding to the above embodiments, the present application also proposes a computer-readable storage medium.

[0083] The computer-readable storage medium of the embodiment of the present invention stores a state detection program of a lifting mechanism, and the state detection program of the lifting mechanism implements the above-mentioned state detection method of the lifting mechanism when executed by a processor.

[0084] According to the computer-readable storage medium of an embodiment of the present invention, the above-mentioned lifting mechanism status detection method is implemented when the processor executes the lifting mechanism status detection program stored thereon. Based on the above-mentioned lifting mechanism status detection method, real-time monitoring of the lifting mechanism is achieved to ensure the operating stability of the lifting mechanism, thereby providing a guarantee for the humidification water of the air conditioner.

[0085] Corresponding to the above embodiment, the present invention further proposes an air-conditioning controller.

[0086] like Figure 7 As shown, the air conditioning controller 100 of the embodiment of the present invention includes a memory 110, a processor 120, and a lifting mechanism status detection method stored in the memory 110 and executable on the processor 120.
