Due to the current high cost and poor detection effect of the method of detecting obstacles in the closing of the air conditioner door panel. The invention provides a solution for detecting the pulse duration during the closing process of the air conditioner opening and closing structure by the detector, and determining whether the current driving step of the driving motor is preset when the pulse duration exceeds the set time threshold. Within the step count range, if the preset opening and closing structure is blocked by the preset, the control motor drives the opening and closing structure to move in the opening direction.

Referring to FIG. 2, an embodiment of the present invention provides a method for controlling opening and closing structure of an air conditioner, and a method for controlling opening and closing structure of the air conditioner includes:

Step S10, receiving a closing instruction of the opening and closing structure, and controlling the motor to drive the opening and closing structure to move in a closing direction thereof;

In this embodiment, the air conditioner is preferably a cabinet type air conditioner, and the cabinet type air conditioner comprises a door panel and a door panel moving device and a door panel driving device, the door panel is connected with the door panel moving device, the door panel moving device is connected with the door panel driving device, and the door panel is connected. The driving device is connected to the controller of the air conditioner, and the door panel moving device is driven by the control panel of the controller under the driving of the door panel driving device. The door panel is an opening and closing structure of the air conditioner, and the door panel is generally arranged for closing and opening of the air outlet of the air conditioner, and the dust enters the air conditioner when the air conditioner is not operated. The opening and closing structure may also be other structures that need to be opened or closed or opened and closed. Of course, the air conditioner is not limited to the cabinet type air conditioner, and may be other air conditioners having an opening and closing (air guiding structure) hanging machine. In this embodiment, a cabinet type air conditioner is taken as an example, and the opening and closing structure is described by taking a door panel as an example.

The air conditioner runs according to the instruction of the user, or automatically starts according to the parameter set in advance, and the operating parameter can be adjusted according to the environmental condition or the instruction of the user requirement during the running process. When the air conditioner is turned off, the door panel needs to be closed. After the compressor of the air conditioner, the indoor fan, and the outdoor fan are turned off, the controller sends a control command (signal) to close the door panel and receive the closing command of the opening and closing structure.

After receiving the closing command, the control motor drives the opening and closing structure to move in the closing direction thereof. If the door panel of the air conditioner is open at this time, it is controlled to move in the direction of closing the door. The door panel may be a single door or a double door. The single door only needs to control the door panel to move in the closing direction, and the double door is the relative movement of the two opposite door panels. The relative movements close to a set position and close, and close each other. The connection can be one of toothing, snapping or fitting.

Step S20, in the process of controlling the closing of the opening and closing structure, determining whether the duration of each pulse signal detected by the detector exceeds a set time threshold;

Referring to FIG. 3, the detector detects that the signal pulse is: the detector includes a magnetic component, and the magnetic component is fixed on the opening and closing structure, the magnetic component has P N magnetic poles and Q S magnetic poles, wherein P , Q is an integer greater than 1; a Hall detecting component, the a Hall detecting components are fixed on the air conditioner body, and the a Hall detecting component is disposed close to the magnetic component, the a The sensing component senses a magnetic change of the magnetic component as the opening and closing structure moves to generate an x-way sensing signal, the sensing model being a signal pulse.

A magnetic ring + Hall sensor that detects the closing of the air conditioner opening and closing structure is provided, and the number of magnetic poles of the magnetic ring is increased to the maximum, so that the number of magnetic poles can be maximized under the premise of being sensed by the Hall sensor, which can further reduce the reaction time. The magnetic pole + Hall sensor is a detector, and the pulse detected by the Hall sensor during the closing process is detected by the detector during the closing process of the air conditioner controlling the opening and closing structure, and each pulse is judged every time a complete pulse is detected. Whether the duration of the signal exceeds a set time threshold; the time threshold is set to Tm*k, k>1, preferably 1.05, for the maximum value Tm of all pulse durations in the normal shutdown of the barrier-free operation.

Preferably, in order to further improve the detection sensitivity, the magnetic ring is no longer mounted on the driving gear, but a high-speed gear is separately used to detect whether the door plate is blocked, and the detecting magnetic ring is mounted on the door panel, and the gear and the electrode gear pass through. Tooth engagement can be n times the rotational speed of the electrode shaft, n>1. At this time, the detection threshold of the signal pulse time becomes 1/n of the original when it is mounted on the drive gear, so that the sensitivity is increased, and it is possible to quickly detect whether or not it is blocked and prevent further damage.

Step S30, if it is exceeded, determining whether the driving step of the driving motor of the current opening and closing structure is within a preset step counting range;

When the duration of the pulse signal detected by the detector exceeds the set time threshold, there may be a detection error. When the first pulse signal is present, there is a timeout, which results in an inaccurate judgment and a false alarm. At this time, it is determined whether the driving step of the driving motor of the current opening and closing structure is within a preset step counting range, and the preset step counting range is a few or dozens of driving steps closest to the closing position to the position. For example, the preset step count range is 8-90. The driving motor of the opening and closing structure is a stepping motor, and the stepping motor rotates by the change of the driving pulse. Each change is called a step, and each step corresponds to an angle of the rotation of the motor, and the driving can drive the door panel to advance a certain distance. The door panel travels the same distance. The ratio of the number of driving steps to the number of output signal pulses is approximately tens or even hundreds of times.

Determining whether the number of driving steps of the driving motor of the current opening and closing structure is within a preset step counting range comprises: determining a counting number of a pulse count of the pulse signal exceeding the time threshold; acquiring the first preset distance from the closing position of the closing door Determining the number of steps; determining whether the counting number is within the first preset step; if so, determining that the driving step of the pulse signal exceeding the time threshold is within the first preset step counting range; Otherwise, it is determined that the number of driving steps of the pulse signal exceeding the time threshold is not within the first preset step count range. Specifically, taking the air conditioner door panel as an example, the number of driving steps required for the whole process of the door panel is determined in advance, and then the number of detection mask steps is set according to the specific situation of the door panel closing in position, and the range of x is 1<= x <p, if there is a docking slot when the door panel is closed, x can be set to the number of driving steps corresponding to the slot depth. For example, the groove depth d, the gear radius r, and the motor rotation angle corresponding to each driving step is deg (unit: radians), then x takes the value d/(r*deg)+p, p takes a non-negative integer, if present For coaxial transmission, the distance needs to be converted. If the door panel has no docking groove, it is directly flat or similar to the direct flat pair, then x is preferably 5~300, and x should be as small as possible when the door is closed and the obstacle is met.

In an embodiment, the step of determining whether the number of driving steps of the pulse signal exceeding the time threshold is within a preset step counting range comprises: determining a counting number of driving steps of the pulse signal exceeding the time threshold; acquiring the opening door a second step counting range of the starting position preset distance; determining whether the counting number is outside the second step counting range; if yes, determining that the driving step of the pulse signal exceeding the time threshold is in the second pre- The step count range is set; if not, the number of driving steps of the pulse signal exceeding the time threshold is determined not to be within the second preset step count range. Specifically, taking the air conditioner door panel as an example, the number of driving steps of the door movement is measured by the experiment, and the shielding pulse s is set according to the specific situation of the door closing door, and the x range is 1 ≤ s <A, if there is a docking groove when the door panel is closed, s can be set to the number of pulses generated by the groove depth. For example, if the door panel has no docking groove, it is directly flat or similar to the direct flat pair, then s is preferably 5~30, and s should take the minimum value when the door is closed and the obstacle is met. If the pulse duration exceeds the set time threshold and the pulse count belongs to a range smaller than A-s, that is, outside the range of the mask, it is determined that an obstacle or a grip is encountered.

In step S40, when the driving step of the pulse signal exceeding the time threshold is within the preset step counting range, it is determined that the opening and closing structure is closed, and the control motor drives the opening and closing structure to move in the opening direction thereof.

When the duration of the pulse signal detected by the detector exceeds the set time threshold, and the number of driving steps is within the preset counting range, if it is within the preset step counting range, it is determined that the opening and closing structure is blocked. There are obstacles, for example, pinching and the like. At this time, in order to prevent the obstacle from being continuously gripped, the control motor drives the opening and closing structure to move in the opening direction thereof. When the opening and closing structure is blocked, the alarm device may be alarmed by the set alarm device, or the alarm information may be sent to the third-party terminal connected thereto through the Internet of Things, so that the third-party terminal user knows that the air conditioner is blocked, and the application scenario is: When the child operates the cabinet air conditioner, the alarm of the child's hand is sent to the guardian's mobile phone, and the guardian is reminded to check in time to prevent further damage to the child.

It can be understood that after controlling the motor to drive the opening and closing structure to move in the opening direction thereof, the distance and time of the operation are detected, and when the time or distance reaches the set value (according to the demand and the actual application setting), the control is continued to the closing direction. motion.

If the duration of the current pulse does not exceed the set time threshold, or the number of driving steps is not within the preset step count range, then the opening and closing structure of the control air conditioner continues to move in the closing direction.

In this embodiment, the detector detects the pulse duration during the closing process of the air conditioner opening and closing structure, and when the pulse duration exceeds the set time threshold, it is determined whether the current driving step of the driving motor is in the preset step counting range. If the preset opening and closing structure is blocked by the preset, the control motor drives the opening and closing structure to move in the opening direction. Through the detector of the simple magnetic ring + Hall sensor, it is detected whether the pulse time is timed out, and after the timeout, it is detected whether the number of steps of the driving motor is detected in the preset step counting range, and the detection cost is reduced, thereby reducing the detection cost. Moreover, whether the detection is blocked by the pulse duration combined with the driving step number makes the detection sensitivity high, improves the detection accuracy and speed, and reduces the damage.

Referring to FIG. 4, in a preferred embodiment of the present invention, in order to further improve the accuracy of the detection of the opening and closing structure, if the exceeding is performed, it is determined whether the number of driving steps of the driving motor of the current opening and closing structure is counted in a preset step. After the steps in the scope, it also includes:

Step S50, when the number of driving steps of the pulse signal exceeding the time threshold is within the first preset counting range, determining whether the pulse count of the pulse signal whose driving step exceeds the preset pulse counting range is within the preset pulse counting range;

In step S60, when the pulse count of the pulse signal whose driving step exceeds the preset step count range is within the preset pulse count range, it is determined that the opening and closing structure is closed, and the control motor drives the opening and closing structure to move in the opening direction thereof.

In this embodiment, when the duration of the pulse signal detected by the detector exceeds the set time threshold, there may be a detection error. When the first pulse signal occurs, there is a timeout, and the judgment is inaccurate. A false positive has occurred. The difference from the first embodiment described above is that, in the present embodiment, based on the duration and the judgment of the stepping motor step number, the judgment of the pulse count is further increased to further avoid the detection error. At this time, it is first determined whether the current driving step number is within the preset step counting range, and when the driving step number is within the preset step counting range, it is determined whether the pulse count of the pulse signal exceeding the time threshold is at the preset counting. In the range, the pulse signal of the preset counting range is the pulse signal closest to the position of the closing door, and the number of driving steps is combined with the number of pulses to further improve the detection accuracy. The process of determining whether the pulse count of the pulse signal whose driving step exceeds the preset step counting range is within the preset pulse counting range includes: determining a counting number of the pulse count of the pulse signal whose driving step exceeds the preset step counting range; Obtaining a pulse counting range of a preset distance from the closed position of the door; determining whether the counting number is within the pulse counting range; if yes, determining a pulse count of the pulse signal whose driving step exceeds the preset step counting range is preset Within the pulse count range; if not, the pulse count of the pulse signal that determines that the number of drive steps exceeds the preset step count range is not within the preset pulse count range. Specifically, taking the air conditioner door panel as an example, the plane butting when the door is closed is changed to the groove docking, so that the normal door closing position and the door panel movement to the last clamping thing are blocked, there is a distance difference, according to this The difference in distance can distinguish between the blockage of the block and the normal closing of the door. The principle of differentiation is as follows: the number of signal pulses of the normal door closing stroke is m1, and the number of stroke pulses that can be blocked by the object is m2, m1>m2, and the m=m1-m2 air-conditioning door closing threshold is also added. One or two pulses are reliably distinguished. During the closing process, each pulse duration is detected in real time. If a pulse duration exceeds the set threshold, it is judged whether the signal pulse counts the range <m1-m, and if so, it is determined that the door panel is in trouble or is pinched.

In an embodiment, the step of determining whether the pulse count of the pulse signal exceeding the preset step count range is within the preset pulse count range comprises: determining a pulse signal whose driving step exceeds the preset step count range a counting number of the pulse count; acquiring a second pulse counting range from the preset distance of the opening position of the opening; determining whether the counting number is outside the second pulse counting range; if yes, determining that the driving step exceeds the preset The pulse count of the pulse signal of the step count range is within the preset pulse count range; if not, the pulse count of the pulse signal that determines that the number of drive steps exceeds the preset step count range is not within the preset pulse count range. Specifically, taking the air conditioner door panel as an example, a total of M pulses are outputted through the experimental measurement of the full stroke detection signal of the door panel, and c shielding pulses are set according to the specific situation of the door closing door position, and the x range is 1 ≤ c < M, if When the door panel is closed, there is a docking slot, and c can be set to the number of pulses generated by the slot depth. For example, the groove depth d, according to the closing speed v, t time to generate a pulse signal, then c takes the value d / v / t + q, q takes an integer, preferably 0 or 1. If the door panel has no docking groove, which is directly flat or similar to direct flat pairing, then c is preferably 1~3, and c should take the minimum value when the door is closed and the obstacle is met. If the pulse duration exceeds the set time threshold and the pulse count belongs to a range smaller than M-c, that is, outside the range of the mask, it is determined that an obstacle or a grip is encountered.

Referring to FIG. 5, in a preferred embodiment of the present invention, in order to further improve the accuracy of the detection of the opening and closing structure, it is determined whether the duration of each pulse signal detected by the detector is determined during the closing of the control opening and closing structure. The steps to exceed the set time threshold include:

Step S21, in the process of controlling the closing of the opening and closing structure, the pulse detector is enabled to detect the pulse signal;

Step S22, after each complete pulse signal is detected, acquiring the duration of the pulse signal and its corresponding time threshold;

Step S23, comparing the duration of the pulse signal with the time threshold;

Step S24, when the duration of the pulse signal is greater than or equal to the time threshold, the determination is exceeded;

In step S25, when the duration of the pulse signal is less than the time threshold, the determination is not exceeded. In the above embodiment, there are differences between the magnetic poles of the magnetic ring, the difference in the Hall components, the difference in the distance between the Hall and the magnetic ring, etc., which ultimately results in a difference in the actual width of the pulse widths of the respective pulse widths, and the detection time is large. Threshold, all pulses have the same duration during normal shutdown. In the embodiment, the initialization is performed when the product is used for the first time, and the detection function is masked during initialization, and the number of signal pulses and the time of each pulse are recorded, and the record is stored. Thereafter, each signal pulse time during the closing process establishes a respective detected time threshold Tn, where Tn is K times the duration of each pulse during the normal closing process, K ≥ 1. When the door closing operation (opening and closing operation is closed), the current signal pulse is taken out, and the corresponding time threshold is taken out to determine the sensitivity, thereby effectively improving the sensitivity of the detection. Of course, it can be understood that K is not constant, and counts the number of normal closing times. When the number of closing times c<n1, K takes the value K1. When n1≤c<n2, the K value takes K2, when n2≤c, K The value takes K3, where n1, n2 and n3 are positive integers greater than 1, and n1 < n2 < n3, K1, K2 and K3 are both greater than 1, and K1 < K2 < K3; meanwhile, the signal is signaled after each normal closing The total number of pulses and each pulse duration are compared with the previous corresponding storage. If it is greater than the stored value, it is updated and the large value is stored.

When the control is turned on and off, each time a signal pulse is detected, the time threshold comparison corresponding to the pulse number is taken out, and if it is exceeded, it is determined that the door panel encounters an obstacle or a hand, and the door panel is driven to move in the opposite direction. The duration of each pulse is basically the same every time, but there will be accidental changes, and the initialization is only performed once. If the data is not updated, there is a risk of misjudgment, and the k value changes according to the increase of the number of normal closing times. Overcoming the above-mentioned repeated consistency problem, avoiding the sudden jump of the duration of a certain signal pulse to cause false detection when the door is closed several times. After the normal closing is enough, the maximum value of each pulse has been recorded, and the probability of false detection is greatly When it is lowered, k is reduced, so that the detection sensitivity is optimized while ensuring reliable and false detection.

Referring to FIG. 6, in a preferred embodiment of the present invention, after the step of enabling the pulse detector to detect the pulse signal during the process of controlling the opening and closing of the opening and closing structure, the method further includes:

Step S26, determining the number of pulses detected by the pulse detector;

In the present embodiment, due to the loose motion of the gear meshing and the looseness of the structure and the deformation of the extrusion, the time of several signal pulses immediately after the door closing is started is higher than the normal operation of the normal pulse duration. Each time the door is closed, the initial j pulses are not judged for the duration of the time, which effectively improves the accuracy of the detection. j is set according to the actual situation and is set as small as possible. It can be understood that, in the first few pulse detections, a compensation value is set, and the duration of the previous j signal pulses is detected after compensation is performed. The scheme of this embodiment is applied to the judgment of uniformly using a duration threshold, and also to the judgment that each signal pulse corresponds to a pulse duration threshold.

In this embodiment, by not judging the duration of the previous pulses, the error is greatly avoided, and the sensitivity and accuracy of the closing detection of the opening and closing structure are improved.

In other embodiments of the present invention, the first signal pulse is not detected, or a preset position is set in the process of closing the opening and closing structure, and the position sensor detects whether the opening and closing structure moves to a preset position. The preset position is superior to the starting position, and is set according to requirements and actual conditions. Of course, if an image capturing device is disposed on the air conditioner, the user information or the obstacle information may be extracted according to the image before the camera device captures the opening and closing structure of the air conditioner, and the preset position should be set according to the information extracted by the screen, thereby avoiding The preset position setting is too small, and the detection has not been started until the hand has been gripped or the obstacle has been clamped, thereby further improving the detection accuracy. Specifically, the control process is: detecting whether the opening and closing structure moves to a preset position; and when the opening and closing structure moves to a preset position, performing the pulse signal after each complete detection of a complete pulse signal is performed The steps of the duration and its corresponding time threshold. The detecting of the preset position may further be: determining a driving step of the driving motor; and when the driving step reaches a preset step threshold, determining that the opening and closing structure moves to a preset position. The process of detecting the preset position is also performed by: controlling the closed position switch to detect the bit signal; and when the in-position switch does not detect the in-position signal, determining that the opening and closing structure moves to the preset position.

In this embodiment, the preset position is set to avoid false detection and timely detection of the front end, thereby improving detection accuracy.

Further, in an embodiment, referring to FIG. 7, before the step of controlling the motor to drive the opening and closing structure to move in the closing direction thereof, the method further includes:

Step S70, detecting whether the opening and closing structure is in an open starting position;

Step S80, if not, controlling the opening and closing structure to move in the opening direction thereof until the opening and closing structure moves to the opening start position;

In this embodiment, each time the door is closed, it is first checked whether the door panel is in the open position, and if not, the door panel is first moved to the door open position. In this way, even if the door panel is considered to be swaying, there is no need to power off and then power on to restore the door panel to normal, and the air conditioner automatically corrects when the door is closed. Or, before receiving the closing instruction of the opening and closing structure, first determining whether the door panel is in the starting position of the door opening, and if so, receiving the closing command of the opening and closing structure, and controlling the motor to drive the opening and closing structure to move in the closing direction thereof; After receiving the opening and closing structure closing command, it may be determined whether the door panel is in the door opening position, and if so, the control motor drives the opening and closing structure to move in the closing direction thereof.

Further, in order to better reset the door panel, when the door panel of the air conditioner is already in the open state, after receiving the door closing command, the door panel is first driven to move in the direction of the door opening t time or e driving steps, so that the door panel is in the door opening position. The pressing structure meshes with the gear to the non-reformable state, and then drives the door panel to move in the closing direction, ensuring that the door closing stroke of the door panel is completely the same, and the number of signal pulses generated is the same. By driving to the door opening position, the starting position of each detection is guaranteed to be the same, ensuring the same number of pulses, which improves the accuracy of the detection of the opening and closing structure.

In an embodiment of the present invention, in order to better detect the detection of the closing obstacle in the opening and closing structure, the opening and closing structure may be controlled to move in the opening direction until the opening and closing structure moves to the opening start thereof. Position; when the opening and closing structure is in the open position, the step of controlling the motor to move the opening and closing structure to the closing direction is performed. The detection of the starting position of the door opening is not performed, and the operation is controlled to the door opening direction before closing the opening and closing structure.

The present invention also provides an air conditioner comprising: an opening and closing structure, a memory and a processor connected to the opening and closing structure, and an air conditioner stored on the memory and operable on the processor The structure control program is configured to implement the opening and closing structure control method of the air conditioner as described above when the opening and closing structure control program of the air conditioner is executed by the processor.

In this embodiment, the detector detects the pulse duration during the closing process of the air conditioner opening and closing structure, and when the pulse duration exceeds the set time threshold, it is determined whether the current driving step of the driving motor is within the preset step counting range. If it is determined by the preset that the opening and closing structure is closed, the control motor drives the opening and closing structure to move in the opening direction thereof. Through the detector of the simple magnetic ring + Hall sensor, it is detected whether the pulse time is timed out, and after the timeout, it is detected whether the number of steps of the driving motor is detected in the preset step counting range, and the detection cost is reduced, thereby reducing the detection cost. Moreover, whether the detection is blocked by the pulse duration combined with the driving step number makes the detection sensitivity high, improves the detection accuracy and speed, and reduces the damage.
