Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present invention and should not be construed as limiting the present invention.
A mobile air conditioner, a control method and apparatus thereof, and a storage medium according to embodiments of the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method of controlling a mobile air conditioner according to an embodiment of the present invention.
As shown in fig. 1, the present invention provides a method of controlling an air conditioner, the method including the steps of:
and S10, detecting the inclination angle of the air conditioner in the operation process.
In particular, during the operation of the air conditioner, that is, when a compressor or other machine is in operation, the whole air conditioner tends to swing, and especially for a mobile air conditioner, if the swing amplitude is large, the air conditioner is easy to topple. In this embodiment, the swing amplitude generated during the operation of the air conditioner may be detected, for example, an angle sensor may be provided to detect the tilt angle during the operation of the air conditioner, wherein the angle sensor includes, but is not limited to, a gyroscope. Certainly, in this embodiment, detecting the inclination angle of the air conditioner is not limited to that the air conditioner is always in the operating state, and when the air conditioner is not in the operating state, the inclination angle of the air conditioner may still be detected, and then the user is reminded through the prompt message.
And S20, controlling the air conditioner step by step according to the detected inclination angle of the air conditioner, and further preventing the air conditioner from toppling over to protect the air conditioner.
Specifically, after the inclination angle of the air conditioner is acquired through the step S10, the air conditioner may be controlled according to the detected inclination angle of the air conditioner, and the air conditioner may be specifically controlled step by step, that is, for different inclination angles, different control instructions may be adopted, so that it is ensured that the air conditioner does not topple over, and it is also ensured that the operation of the air conditioner is not greatly affected. For example, when the inclination angle of the air conditioner is a first angle, the air conditioner is controlled by adopting a first-level control instruction; when the inclination angle of the air conditioner is a second angle, the air conditioner is controlled by adopting a second-level control instruction; by analogy, the operation parameters of the air conditioner can be ensured not to be changed too much, the use requirements of users can be ensured, and then the phenomenon of toppling of the air conditioner can be prevented.
In one embodiment of the present invention, as shown in fig. 1 and 2, the step S20 of controlling the air conditioner step by step according to the detected tilt angle of the air conditioner may include the steps of:
s201, further determining the current inclination degree of the air conditioner according to the detected inclination angle of the air conditioner. And S202, controlling the air conditioner step by step according to the current inclination degree of the air conditioner.
Specifically, in this embodiment, if the tilt angle of the air conditioner is detected, the current tilt degree of the air conditioner may be further determined, for example, the tilt degree may be divided into a first stage, a second stage, a third stage, and the like, where the first stage may be a non-tilt stage, the second stage may be a slight tilt stage, and the third stage may be a severe tilt stage, and then the air conditioner may be controlled by different control commands corresponding to different tilt degrees. For example, if it is detected that the air conditioner is not tilted, the current operation mode may be maintained; and if the air conditioner is detected to be slightly inclined, the air conditioner can be controlled to respond to corresponding instructions; if it is detected that the air conditioner is severely tilted, the air conditioner may be controlled to be turned off. The inclination degree of the air conditioner may be divided into different levels, which may be set and selected by the user, or may be set by the manufacturer before the air conditioner leaves the factory. It will be appreciated that different degrees of control accuracy may be determined for different numbers of levels, for example, where the degree of air conditioner tilt is divided into 5 levels, with greater control accuracy than where the degree of air conditioner tilt is divided into 3 levels.
In an embodiment of the present invention, as shown in fig. 1 and 3, the step S20 of controlling the air conditioner step by step according to the detected tilt angle of the air conditioner may include the following steps:
s301, when the air conditioner is in a normal operation state, acquiring a reference angle of the air conditioner, and then comparing the current inclination angle of the air conditioner with the reference angle to obtain an angle difference.
First, it should be noted that, as shown in fig. 4, the protection method for preventing the air conditioner from falling down according to the embodiment of the present invention can be applied to the device for preventing the air conditioner from falling down shown in the figure, and specifically, as shown in fig. 4, an anti-falling switch is disposed in the power supply system of the ac power supply and the air conditioner, and the power supply system can supply power to the gyroscope, the central processing unit, and the compressor to enable the gyroscope, the central processing unit, and the compressor to operate normally.
Specifically, in this embodiment, when the air conditioner is in the normal operation state, the reference angle of the air conditioner may be acquired first, and more specifically, the acquisition of the reference angle of the air conditioner may be an average angle of the air conditioner inclination of the first 5 seconds after the air conditioner is turned on to operate. That is, when the air conditioner starts to normally operate, the tilt angle of the air conditioner may be acquired for 5 seconds before the air conditioner, and it is understood that a plurality of tilt angles may be acquired, and then averaged, and the average value may be used as the final reference angle of the air conditioner. It should be noted that the reference angle of the air conditioner may be different every time the air conditioner operates, and therefore, the reference angle needs to be obtained again every time the air conditioner operates. Of course, the reference angle of the air conditioner may be obtained again when the air conditioner changes the operation position, and if the air conditioner does not change the operation position, the air conditioner may participate in the control according to the original reference angle.
After the reference angle of the air conditioner is obtained, the inclination angle of the air conditioner during operation can be further obtained, and then the inclination angle is compared with the reference angle to obtain the angle difference. Specifically, the central processing unit can monitor and record the current pouring angle of the air conditioner in real time through the gyroscope.
And S302, if the angle difference is larger than the first preset angle threshold value, the operation frequency of the compressor of the air conditioner can be reduced, the operation system of the air conditioner can be subjected to pressure reduction, then the current inclination angle of the air conditioner is further obtained, and whether the inclination angle is larger than a second preset angle threshold value or not is judged, wherein the second preset angle threshold value is larger than the first preset angle threshold value.
Specifically, after the angle difference between the current inclination angle and the reference angle of the air conditioner is obtained, the angle difference is judged, and if the angle difference is larger than a first preset angle threshold value, the operation frequency of an air conditioner compressor can be reduced, the pressure of an operation system of the air conditioner is reduced, impact is reduced, and the swing amplitude of the air conditioner compressor in the operation process can be reduced. And then, running at the adjusted running frequency of the compressor, obtaining the current dumping angle of the air conditioner again, comparing the obtained dumping angle with a second preset angle threshold value, and performing the next step of control according to the comparison result. It should be noted that the second preset angle threshold in this embodiment is larger than the first preset angle threshold, that is, after the tilting angle of the air conditioner is compared and adjusted with the first preset angle threshold, it is determined whether the adjusted tilting angle of the air conditioner is larger than the second preset angle threshold, if so, a higher level of control may be performed to ensure that the air conditioner can operate smoothly, and if not, the control may be maintained.
And S303, if the current inclination angle of the air conditioner is larger than the second preset angle threshold value, controlling the compressor of the air conditioner to be directly closed, further acquiring the current inclination angle of the air conditioner, and judging whether the inclination angle is larger than a third preset angle threshold value, wherein the third preset angle threshold value is larger than the second preset angle threshold value.
Specifically, after the pour angle of the air conditioner adjusted in step S302 is obtained, the inclination angle may be compared with a second preset angle threshold, and if it is determined that the current inclination angle is greater than the second preset angle threshold, the compressor of the air conditioner may be directly turned off to stop the operation of the compressor of the air conditioner, so as to achieve the purpose that the air conditioner can be stabilized. It is understood that other devices of the air conditioner, such as a fan, etc., may be normally operated after the air conditioner turns off the compressor. After the air conditioner shuts off the compressor, the current inclination angle of the air conditioner can be further acquired, and then whether the inclination angle is larger than a third preset angle threshold value is judged, wherein the third preset angle threshold value is larger than a second preset angle threshold value. That is, after the dump angle of the air conditioner is greater than the second preset angle threshold and the compressor is turned off, it may be determined whether the dump angle of the air conditioner is greater than a third preset angle threshold greater than the second preset angle threshold, and if so, the air conditioner may be controlled to a higher level, and if not, the air conditioner may be maintained
And S304, if the current inclination angle of the air conditioner is judged to be larger than the third preset angle threshold value, directly cutting off the power supply of the air conditioner.
Specifically, after the dump angle of the air conditioner adjusted in step S303 is obtained, the dump angle may be compared with a third preset angle threshold, and if it is determined that the current dump angle of the air conditioner is greater than the third preset angle threshold, the power supply of the air conditioner may be directly cut off, and more specifically, as shown in fig. 4, the power supply system of the air conditioner may be directly cut off from the ac power supply through the anti-dump switch, so that the air conditioner is completely powered off, and the air conditioner is ensured to be stable. It can be understood that, when the tipping angle of the air conditioner is greater than the third preset angle threshold, it indicates that the air conditioner is currently about to tip over, so in this embodiment, the air conditioner is powered off, and therefore, even if the air conditioner has a tipping phenomenon, the air conditioner can be powered off in advance, and the damage degree of the air conditioner is reduced.
As shown in fig. 5, to summarize the method for controlling an air conditioner according to an embodiment, specifically, referring to fig. 4 and 5, firstly, during the operation of the air conditioner, the central processing unit monitors and records the current dumping angle a of the air conditioner in real time through the gyroscope, and records the reference angle Ab when the air conditioner is normally operated, and when the change angle of the gyroscope is detected to exceed the preset change range angle a1, the central processing unit controls the compressor of the air conditioner to start to decrease the frequency, and simultaneously reduces the pressure and the impact of the refrigeration system, and then obtains the dumping angle of the air conditioner through the gyroscope. When the inclination angle of the gyroscope exceeds a preset inclination angle A2, the central processing unit controls to turn off the operation of the compressor of the air conditioner. When the inclination angle of the air conditioner reaches the triggering angle A3 of the anti-toppling switch, the anti-toppling switch directly cuts off the power supply of the whole air conditioner. The method can be used for protecting the internal devices of the air conditioner step by step according to the sensitivity degree of the inclination angle. Not only effectively protected the inside device of air conditioner, made the air conditioner more intelligent moreover, promoted user experience greatly, increased the selling point of air conditioner simultaneously.
As shown in fig. 6, in an embodiment of the present invention, during the operation of the air conditioner, the central processing unit monitors and records the current dumping angle a of the air conditioner in real time through the gyroscope, and records the reference angle Ab when the air conditioner is operating normally, and when detecting that the change angle of the gyroscope exceeds the preset change range angle of 2 degrees, the central processing unit controls the compressor of the air conditioner to start frequency reduction, and reduces the pressure and impact of the refrigeration system, and then obtains the dumping angle of the air conditioner through the gyroscope. When the inclination angle of the gyroscope exceeds the preset inclination angle by 15 degrees, the central processing unit controls to close the compressor of the air conditioner. When the inclination angle of the air conditioner reaches 75 degrees of the triggering angle of the anti-toppling switch, the power supply of the whole air conditioner is directly cut off by the anti-toppling switch. The method can protect the internal devices of the air conditioner step by step according to the sensitivity degree of the inclination angle. Not only effectively protect the internal devices of the air conditioner, but also make the air conditioner more intelligent, greatly improve the user experience and increase the selling points of the air conditioner.
In some embodiments of the present invention, as shown in fig. 7, before detecting the tilt angle of the air conditioner during operation, the following steps may be further included:
and S701, receiving a calibration instruction of the inclination angle of the air conditioner.
S702, acquiring initial angle information of the air conditioner according to the received calibration instruction, and then using the initial angle information of the air conditioner as information used by the air conditioner for calibrating the reference angle, so that when the inclination angle of the air conditioner is detected, the inclination angle of the air conditioner can be calibrated according to the calibrated information of the reference angle.
Specifically, the air conditioner often results in that it can not be installed on ground horizontally in the process of installing, or because of its installed position, so if this embodiment directly carries out the comparison with the horizontal angle with the inclination angle of air conditioner, cause the error very easily, and then cause the mistake to control to the air conditioner. Therefore, before the inclination angle of the air conditioner in the operation process is detected, the embodiment of the invention can calibrate the inclination angle of the air conditioner. More specifically, an inclination angle calibration instruction of the air conditioner is received first, and then initial angle information of the air conditioner is obtained according to the received calibration instruction, where the initial angle information of the air conditioner may include, but is not limited to, an overlook angle information, an elevation angle information, and a rolling angle, and it needs to be noted that the initial angle information of the air conditioner may be obtained by setting a gyroscope on the air conditioner, and certainly, may also be obtained by setting other obtaining modules. After the initial angle information is acquired, the initial angle information is used as information for calibrating the reference angle of the air conditioner, for example, the initial angle is inclined to the right by 1 degree in the installation process of the air conditioner, so that after the gyroscope receives a calibration instruction for the inclination angle of the air conditioner, the initial angle of the air conditioner can be detected to be inclined to the right by 1 degree, and then the reference angle can be calibrated (i.e., the reference angle is calibrated to be inclined to the right by 1 degree) according to the initial angle information of the air conditioner (i.e., inclined to the right by 1 degree), so that when the inclination angle of the air conditioner is detected, the inclination angle of the air conditioner can be calibrated according to the calibrated information of the reference angle.
It should be noted that, the calibration instruction in this embodiment may be sent by the intelligent terminal device, specifically, the calibration instruction may be sent to the air conditioner by installing a corresponding application program on the intelligent terminal device and then sending the calibration instruction to the air conditioner by the application program.
In an embodiment of the present invention, the initial angle information of the air conditioner may include an initial top view angle, and an initial rolling angle of the air conditioner detected by a gyroscope, and the calibrating the tilt angle of the air conditioner according to the information of the reference angle that has been calibrated may include: and respectively subtracting the corresponding initial overlooking angle, initial upgoing angle and initial rolling angle from the real-time overlooking angle, upgoing angle and rolling angle detected by the gyroscope arranged on the air conditioner, so as to obtain the final overlooking angle, upgoing angle and rolling angle, and taking the final angle as the current inclination angle of the air conditioner.
First, although the gyroscopes are calibrated at a fixed angle before shipment and are used as horizontal reference surfaces, when the gyroscopes are installed in air conditioners, it is not guaranteed that all the gyroscopes can be accurately installed at the factory-calibrated angle due to the structure, the air conditioner position, and the like, and thus a measurement error occurs. In this embodiment, first, corresponding initial angles are subtracted according to a real-time overlook angle, a real-time upward view angle and a rolling angle detected by a gyroscope arranged on the air conditioner, that is, the real-time overlook angle is subtracted by the initial overlook angle, the real-time upward view angle is subtracted by the initial upward view angle, and the real-time rolling angle is subtracted by the initial rolling angle, so that a final overlook angle, a final upward view angle and a final rolling angle are obtained, and then the obtained final angle is used as a current inclination angle of the air conditioner.
For example, if the initial top view angle of the air conditioner is 1 degree, the initial top view angle is also 1 degree, and the initial rolling angle is 1 degree, after the real-time top view angle is 2 degrees, and the real-time rolling angle is 2 degrees are obtained through the gyroscope, the obtained real-time angle is subtracted by the initial angle to obtain a final angle, which is used as the current inclination angle of the air conditioner.
In an embodiment of the present invention, when a calibration instruction for calibrating the tilt angle of the air conditioner is received, the air conditioner may be controlled to enter a corresponding calibration mode, so as to obtain information of the reference angle of the air conditioner.
Specifically, in this embodiment, the air conditioner may be controlled to operate in the calibration mode when the instruction is received, and more specifically, the calibration mode of the air conditioner may be to control the air conditioner to be in a shutdown state but not to be powered off to maintain the communication function of the air conditioner. It can be understood that, when the air conditioner is in a shutdown state, the current inclination angle of the air conditioner is the inclination angle considering factors such as a gyroscope installation error and an air conditioner position, so that information of a reference angle of the air conditioner can be obtained by obtaining the inclination angle of the air conditioner in the mode, when the true inclination angle of the air conditioner is obtained subsequently, the true inclination angle of the air conditioner can be obtained by calculating according to the obtained information of the real-time inclination angle and the reference angle of the air conditioner, and then the air conditioner is controlled according to the inclination angle. In some embodiments, the real-time detection of the tilt angle of the air conditioner may be after the air conditioner exits the calibration mode. It is understood that when the air conditioner exits from the calibration mode, it indicates that the air conditioner has completed the calibration of the tilt angle, so the detection of the tilt angle can be performed in real time next.
As shown in fig. 8, after the air conditioner is powered on, it may be determined whether the air conditioner receives a calibration command, if so, receiving the pitch angle and the roll angle detected by the gyroscope, storing the pitch angle and the roll angle in a memory, then judging whether a calibration instruction is received again, if the air conditioner does not receive the calibration instruction, receiving the current depression angle and roll angle of the gyroscope, then reading the pitch angle and the roll angle which are stored in the memory before, determining the final pitch angle and the final roll angle through the pitch angle and the roll angle which are detected in real time and the pitch angle and the roll angle which are stored in the memory, and obtaining the current inclination angle of the air conditioner according to the final pitch angle and the final roll angle, and finally controlling the air conditioner step by step according to the current inclination angle of the air conditioner.

In particular, during the operation of the air conditioner, that is, when a compressor or other machine is in operation, the whole air conditioner tends to swing, and especially for a mobile air conditioner, if the swing amplitude is large, the air conditioner is easy to topple. In this embodiment, the detection module 101 may be used to detect the swing amplitude generated during the operation of the air conditioner, for example, an angle sensor may be provided to detect the tilt angle during the operation of the air conditioner, where the angle sensor includes, but is not limited to, a gyroscope. Certainly, in this embodiment, detecting the inclination angle of the air conditioner is not limited to that the air conditioner is always in the operating state, and when the air conditioner is not in the operating state, the inclination angle of the air conditioner may still be detected, and then the user is reminded through the prompt message.

When the inclination angle of the gyroscope exceeds a preset inclination angle A2, the central processing unit controls the operation of a compressor of the air conditioner to be turned off. When the inclination angle of the air conditioner reaches the triggering angle A3 of the anti-toppling switch, the anti-toppling switch directly cuts off the power supply of the whole air conditioner. The method can protect the internal devices of the air conditioner step by step according to the sensitivity degree of the inclination angle.
