Referring to fig. 2, an embodiment of the present invention provides a method for controlling an opening and closing structure of an air conditioner, including:
step S10, receiving a closing instruction of the opening and closing structure, and controlling a motor to drive the opening and closing structure to move towards the closing direction;
in this embodiment, the air conditioner is preferably a cabinet air conditioner, the cabinet air conditioner includes a door panel, a door panel movement device, and a door panel driving device, the door panel is connected to the door panel movement device, the door panel movement device is connected to the door panel driving device, the door panel driving device is connected to a controller of the air conditioner, and the door panel movement device moves according to the control door panel of the controller under the driving of the door panel driving device. The door plate is an opening and closing structure of the air conditioner, and the door plate is generally arranged for closing and opening an air outlet of the air conditioner, so that dust is prevented from entering the air conditioner when the air conditioner does not operate. The opening and closing structure can also be other structures which need to be opened and closed or can be opened and closed. Of course, the air conditioner is not limited to the cabinet air conditioner, and may be other air conditioners having an opening/closing (air guiding structure) on-hook unit. In the present embodiment, a cabinet air conditioner is taken as an example, and a door panel is taken as an example for the opening and closing structure.
The air conditioner is operated according to the instruction of a user or automatically started to operate according to the preset parameters, and the operation parameters can be adjusted according to the environmental conditions or the instruction of the user requirement in the operation process. And when the air conditioner is closed, the door panel needs to be closed. After the compressor, the indoor fan and the outdoor fan of the air conditioner are closed, the controller sends a control command (signal) to close the door plate and receives a closing command of the opening and closing structure.
After receiving the closing instruction, the control motor drives the opening and closing structure to move towards the closing direction. If the door plate of the air conditioner is opened at the moment, the door plate is controlled to move towards the door closing direction. The door plate can be a single door or a double door, the single door only needs to control the door plate to move towards the closing direction, the double door is formed by relative movement of two opposite sub-door plates, the two sub-door plates meet and close at a set position after relative movement, and the connection mode of the meeting and closing position can be one of meshing, meshing or attaching.
Step S20, controlling the light emitting tube and the light receiving tube which are used for detecting the closing position of the opening and closing structure to be opened;
the infrared light emitting tube and the light collecting tube are arranged at the closing position of the opening and closing structure of the air conditioner, the infrared light emitting tube and the light collecting tube are arranged in a V shape, the angle is related to the distance d between the upper edge and the lower edge of the opening and closing structure (determined according to which edge the pair of tubes are arranged) and the distance l between the two tubes, and the angle deg of the V shape is 2tan (l/2/d). When a closing instruction of the opening and closing structure is received, the motor is controlled to drive the opening and closing structure to move towards the closing direction of the opening and closing structure, the light emitting tube and the light receiving tube which are arranged and used for detecting the closing in-place position of the opening and closing structure are controlled to be opened, and whether the opening and closing structure moves to the closing in-place position is detected through the arranged light emitting tube and the light receiving tube. The luminotron emits infrared rays, and the light receiving tube is connected with the infrared rays emitted by the light receiving tube; when the opening and closing structure does not move to the closed in-place position, the light beams emitted by the light emitting tube are reflected by the edge of the opening and closing structure, the light receiving tube receives the reflected light beams, and the in-place signals are output. Meanwhile, the luminous and light receiving geminate transistors can be mounted on the upper side and the lower side of the door plate at the in-place position without being mounted in a V shape, the light receiving tubes always receive light beams when the door plate is not in place, and when the door plate is in place, the light beams of the light emitting tubes are blocked, and the light receiving tubes do not receive the light beams and send door plate in-place signals to a master control.
Step S30, before the light receiving tube does not output the open-close structure in-place signal, judging whether the duration of each pulse signal detected by the detector exceeds the set time threshold;
before the light receiving tube outputs the in-place signal, namely before the light receiving tube does not output the in-place signal of the opening and closing structure, and before the opening and closing structure is not closed, the condition that the closing is blocked exists, and whether the blocking is detected is judged by detecting the duration time of the pulse signal detected by the detector in the closing process of the opening and closing structure. When the opening and closing structure is opened and closed on two sides, for example, when the door panel is a double-side door panel, two groups of light emitting tubes and light collecting tubes are arranged, and before one of the light collecting tubes does not output an opening and closing structure in-place signal on the edges of the door panels on two sides, whether the duration time of each pulse signal detected by the detector exceeds a set time threshold value or not is judged.
Referring to fig. 3, the detector detects the signal pulses as: the detector comprises a magnetic component, wherein the magnetic component is fixed on the opening and closing structure and is provided with P N magnetic poles and Q S magnetic poles, and P and Q are integers more than 1; the X Hall detection assemblies are fixed on the air conditioner body and close to the magnetic assembly, the X Hall detection assemblies sense the magnetic change of the magnetic assembly to correspondingly generate an X-path sensing signal when the opening and closing structure moves, and the sensing model is a signal pulse.
The magnetic ring and the Hall sensor are arranged for detecting the closing of the opening and closing structure of the air conditioner, the number of the magnetic poles of the magnetic ring is increased extremely, the number of the magnetic poles of the magnetic ring is maximized on the premise that the magnetic poles can be sensed by the Hall sensor, and therefore the reaction time can be further shortened. The magnetic pole and the Hall sensor are detectors, pulses detected by the Hall sensor in the closing process are detected by the detectors in the closing process of the air conditioner control opening and closing structure, and whether the duration time of each pulse signal exceeds a set time threshold value is judged when each complete pulse is detected; the time threshold is set at the maximum Tm of all pulse durations in the barrier-free normal shutdown or to Tm × k, k >1, preferably 1.05.
Preferably, in order to further improve the detection sensitivity, the magnetic ring is not mounted on the driving gear, but a high-speed gear is independently made for detecting whether the door panel is blocked, the magnetic ring for detection is mounted on the door panel, and the gear and the electrode gear are meshed and can be n times of the rotating speed of the electrode shaft, wherein n is greater than 1. At this time, the detection threshold of the signal pulse time is changed to 1/n of the original detection threshold when the signal pulse time is originally mounted on the driving gear, so that the sensitivity is increased, whether the signal pulse time is blocked or not can be quickly detected, and further damage can be prevented.
After the light receiving tube outputs an opening and closing structure in-place signal, judging that the opening and closing result is closed, and controlling the motor to stop running; and after the preset time for controlling the motor to stop running, controlling the light emitting tube and the light receiving tube to be closed.
And step S40, if the current situation exceeds the preset threshold value, judging that the opening and closing structure is blocked, and controlling the motor to drive the opening and closing structure to move towards the opening direction.
When the duration of the pulse signal detected by the detector exceeds a set time threshold, it is determined that the closing of the opening and closing structure is blocked and an obstacle, such as a hand, is present. At this time, in order to prevent the obstacle from being clamped continuously, the motor is controlled to drive the opening and closing structure to move towards the opening direction. When the structure that opens and shuts is closed and is obstructed, the alarm device that the accessible set up reports to the police, perhaps sends alarm information to rather than the third party terminal of being connected through the mode of thing networking to supply third party end user to know that the air conditioner is closed and is obstructed, use the sight and do: when the child operates the cabinet air conditioner, the alarm that the child is clipped is sent to the mobile phone of the guardian, so that the guardian is reminded to check in time to prevent the child from further injury.
It can be understood that after the control motor drives the opening and closing structure to move towards the opening direction, the running distance and time are detected, and when the time or the distance reaches a set value (set according to requirements and practical application), the control motor continues to control the opening and closing structure to move towards the closing direction.
And if the duration time of the current pulse does not exceed the set time threshold, controlling the opening and closing structure of the air conditioner to continue moving towards the door closing direction.
In the embodiment, the light emitting tube and the light receiving tube are arranged on the opening and closing structure, when the light receiving tube outputs a target signal, the opening and closing structure is closed, before the light receiving tube does not output the target signal, the possibility of blocking the closing exists, the detector is arranged to detect the pulse duration of the opening and closing structure of the air conditioner in the closing process, when the pulse duration exceeds a set time threshold, the opening and closing structure is judged to be blocked, and the motor is controlled to drive the opening and closing structure to move towards the opening direction of the opening and closing structure. Whether open and shut the structure through the luminotron with receive the luminotron and judge and close whether target in place, the simple magnetic ring of rethread + hall sensor's detector realizes that the structure that opens and shuts closes the obstructed detection, has reduced the detection cost, and makes sensitivity high through pulse duration's judgement, has improved the degree of accuracy that detects, reduces and closes the obstructed injury.
Referring to fig. 4, in a preferred embodiment of the present invention, after the step S40, the method further includes:
step S50, after the control motor drives the opening and closing structure to move towards the opening direction for a preset time, executing the step of controlling the motor to drive the opening and closing structure to move towards the closing direction;
and step S60, after the times of stopping the closing of the opening and closing structure are judged to reach the preset times, the motor is controlled to drive the opening and closing structure to move to the opening initial position towards the opening direction, and the motor is controlled to stop running.
After the closing is blocked, the opening and closing structure needs to be closed again after the opening direction of the opening and closing structure is operated for a preset time. The preset time can be 8s or 10s and the like, and is set according to the opening and closing time of the opening and closing structure or the user requirement. If the continuous closing is blocked, the opening/closing operation of the opening/closing structure can be continuously performed according to the mode, after the number of times of the blocking of the opening/closing operation is judged to reach the preset number, the motor is controlled to drive the opening/closing structure to move to the opening starting position towards the opening direction, and the motor is controlled to stop running. That is, after the preset times of closing is reached and the closing is blocked, the opening/closing operation of the opening/closing structure is not executed any more, the opening/closing structure is controlled to move to the opening initial position, the resource waste is avoided, and repeated damage caused by continuous blocking or damage caused to the air conditioner structure is avoided.
Referring to fig. 5, in order to further improve the accuracy of detecting the open-close structure, in a preferred embodiment of the present invention, before the light receiving tube does not output the open-close structure in-place signal, the step of determining whether the duration of each pulse signal detected by the detector exceeds a set time threshold includes:
step S21, before the light receiving tube does not output the open-close structure in-place signal, the pulse detector is started to detect the pulse signal;
step S22, after each complete pulse signal is detected, the duration of the pulse signal and the corresponding time threshold value are obtained;
step S23, comparing the duration of the pulse signal with the time threshold;
a step S24 of determining that the pulse signal exceeds the time threshold when the duration of the pulse signal is greater than or equal to the time threshold;
and step S25, when the duration of the pulse signal is less than the time threshold, determining that the duration is not exceeded.
In the above embodiment, the difference between the magnetic poles of the magnetic ring, the difference between the hall elements, the difference between the hall and the magnetic ring, and the like, eventually result in that the actual width difference of the pulses of the same signal width is large, and the detected time threshold value is the same as the duration time of all the pulses in the normal closing process. In the embodiment, the product is initialized when being used for the first time, the detection function is shielded during initialization, the number of the signal pulses and the time of each pulse are recorded during the whole door closing process, and the records are stored. And then, establishing a respective detected time threshold Tn for each signal pulse time in the door closing process, wherein Tn is K times of each pulse duration in the normal door closing process, and K is more than or equal to 1. When door closing operation (closing operation of the opening and closing structure) is carried out, the current signal pulse is the first signal pulse, namely, the corresponding time threshold value is taken out to judge, so that the detection sensitivity is effectively improved. It can be understood that K is not constant, and is counted as the normal gate closing times, when the gate closing times c is less than n1, K takes the value K1, when n1 is less than or equal to c and less than n2, K takes the value K2, when n2 is less than or equal to c, K takes the value K3, where n1, n2, and n3 are positive integers greater than 1, n1< n2< n3, K1, K2, and K3 are all greater than 1, and K1< K2< K3; meanwhile, after the door is normally closed each time, the total number of the signal pulses is compared with the duration of each pulse, and the duration of each pulse is compared with the duration of the corresponding pulse, if the total number of the signal pulses is larger than the duration of each pulse, the comparison is updated, and a large value is stored.
Before the light receiving tube does not output an opening and closing structure in-place signal, when a signal pulse is detected, the corresponding time threshold value corresponding to the pulse serial number is taken out for comparison and judgment, if the time threshold value is exceeded, the door panel is judged to be in obstacle or clamped, and the door panel is driven to move in the opposite direction. The duration of each pulse is basically consistent every time the door is closed, but the pulse is changed more and more accidentally, the initialization is only carried out once, if the data are not updated, the risk of misjudgment exists, meanwhile, the k value is changed according to the increase of the normal door closing times, the problem of repeated consistency is also solved, the problem that when the door is just closed for a few times, the duration of a certain signal pulse suddenly jumps to cause misdetection is avoided, after the door is normally closed enough, the maximum value of each pulse is recorded, the misdetection probability is greatly reduced, the k is reduced, the detection sensitivity is enabled to be optimal, and meanwhile, the reliable misdetection is guaranteed.
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 before the light receiving tube does not output the on-off structure bit signal, the method further includes:
step S26, determining the number of pulses detected by the pulse detector;
and when the number of the current pulses reaches a preset number threshold, executing the step of acquiring the duration of the pulse signals and the corresponding time threshold after each complete pulse signal is detected.
In this embodiment, the time of the first few signal pulses after the door closing start is much longer than the normal operation normal pulse duration due to the idle stroke of the gear engagement, the loose structure, the compression deformation, and the like. Every time the door is closed, the duration length of the initial s pulses is not judged, the detection accuracy is effectively improved, and s is set according to actual conditions and is set as small as possible. It will be appreciated that in the detection of the first few pulses, a compensation value is set, and the duration of the first s signal pulses is detected after compensation has been made. The scheme of the embodiment is applied to the judgment of uniformly using one duration threshold value and also adapts to the judgment of corresponding one pulse duration threshold value to each signal pulse.
According to the embodiment, the misjudgment caused by large errors is avoided by not judging the duration of the previous pulses, and the sensitivity and the accuracy of the closing detection of the opening and closing structure are improved.

Specifically, the control process is as follows: detecting whether the opening and closing structure moves to a preset position or not; and when the opening and closing structure moves to a preset position, executing the step of acquiring the duration time of the pulse signal and the corresponding time threshold value after detecting each complete pulse signal. The detection of the preset position may also be: determining the driving step number of a driving motor; and when the driving step number reaches a preset step number threshold value, judging that the opening and closing structure moves to a preset position. The process of detecting the preset position also comprises the following steps: controlling to close the in-place switch to detect an in-place signal; and when the in-place switch does not detect the in-place signal, judging that the opening and closing structure moves to a preset position. The in-place switch can be replaced by the light emitting tube and the light receiving tube in the embodiment, and the arrangement mode is consistent with the above. And outputting an in-place signal indicating whether the opening and closing structure is in place or not through the light collecting tube. The position is predetermine through setting up to this embodiment, avoids the false detection and the timely detection of front end, improves detection accuracy.
