As described in the background art, in order to solve the problem that the rotation speed of the inner fan of the photovoltaic air conditioner is unstable, the embodiment of the application provides a control method and a control device of the photovoltaic air conditioner, a computer readable storage medium and the photovoltaic air conditioner.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

In the present embodiment, a control method of a photovoltaic air conditioner operating on a mobile terminal, a computer terminal, or a similar computing device is provided, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different from that herein.

Fig. 1 is a flowchart of a control method of a photovoltaic air conditioner according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:

Step S201, obtaining an initial wind sweeping angle of a wind sweeping plate of a photovoltaic air conditioner and an initial wind sweeping speed of the wind sweeping plate, and detecting the rotating speed of an inner fan of the photovoltaic air conditioner according to a first preset time interval to obtain a first rotating speed of the inner fan corresponding to each first sampling moment, wherein the time interval of every two adjacent first sampling moments is the first preset time interval;

specifically, in order to reduce consumption of non-renewable energy sources, the photovoltaic air conditioning system is powered by a photovoltaic power supply, when the photovoltaic air conditioner is started to sweep air up, down, left and right, the rotating speed of a fan in the air conditioner can generate certain fluctuation, and further the air quantity of an air outlet is negligibly small, so that the experience of a user is poor. According to multiple experiments, when a certain windshield is set by the inner machine, the air outlet uniformity of the inner machine is judged to be in a qualified state only when the fluctuation of the rotation speed is smaller than 15r (revolutions), so that the air outlet uniformity of the inner machine can not be caused by the running of the air conditioner as long as the maximum fluctuation of the rotation speed is kept to be not more than 15r in the running process. Therefore, the rotating speed of the inner fan is stable by adjusting the wind sweeping plate, the initial wind sweeping angle and the initial wind sweeping speed of the wind sweeping plate are obtained, and the first preset time interval can be 1s, namely the rotating speed of the inner fan of the photovoltaic air conditioner is detected every second.

Step S202, when the absolute value of the difference value of the rotating speeds of the first inner fans corresponding to the two adjacent first sampling moments is larger than a rotating speed threshold value, acquiring an adjusting angle and an adjusting speed, calculating the difference value of the initial wind sweeping angle and the adjusting angle to obtain a target wind sweeping angle, and calculating the sum of the initial wind sweeping speed and the adjusting speed to obtain a target wind sweeping speed;

Specifically, the difference value of the rotation speeds of the first inner fans corresponding to two adjacent first sampling moments is represented by N _n+1-N_n, and when N _n+1-N_n is detected to be larger than 15r, the rotation speed fluctuation is larger, so that the adjustment angle and the adjustment speed are obtained, and the difference value is calculated to obtain the target wind sweeping angle and the target wind sweeping speed, so that the wind sweeping angle and the wind sweeping speed are reduced.

And step S203, controlling the wind sweeping angle of the wind sweeping plate to be the target wind sweeping angle and the wind sweeping speed of the wind sweeping plate to be the target wind sweeping speed.

Specifically, after the target wind sweeping angle and the wind sweeping speed are calculated, the wind sweeping angle and the wind sweeping speed of the air conditioner are controlled to be the target wind sweeping angle and the target wind sweeping speed, so that the fluctuation of the rotating speed of an inner fan of the air conditioner is reduced, and the target is N _n+1-N_n < 15r.

According to the embodiment, the rotation speed of the inner fan is collected according to the first preset time interval, and under the condition that the absolute value of the difference value of the rotation speeds of the inner fans at two adjacent first sampling moments is larger than the rotation speed threshold value, the air sweeping angle of the air conditioner is controlled to be reduced to be a target air sweeping angle, and the air sweeping speed of the air conditioner is controlled to be reduced to be a target air sweeping angle, so that fluctuation of the rotation speed of the inner fan is reduced by reducing the air sweeping angle and the air sweeping speed, and the rotation speed of the inner fan tends to be stable. Compared with the prior art that the unstable rotation speed of the inner fan can be caused by the up-down, left-right wind sweeping of the wind sweeping plate, the application ensures that the rotation speed of the inner fan tends to be stable by adjusting the wind sweeping angle and the wind sweeping speed of the wind sweeping plate, thus solving the problem of unstable rotation speed of the inner fan of the photovoltaic air conditioner in the prior art, improving the stability of the rotation speed of the inner fan and further ensuring that the air output of the air conditioner tends to be stable.

In a specific implementation process, the step S202 obtains an adjustment angle and an adjustment speed, calculates a difference value between the initial wind sweeping angle and the adjustment angle to obtain a target wind sweeping angle, and calculates a sum of the initial wind sweeping speed and the adjustment speed to obtain a target wind sweeping speed, which may be implemented by the following steps: under the condition that the photovoltaic air conditioner is started in an up-down wind sweeping mode or a left-right wind sweeping mode, a first adjustment angle and a first adjustment speed are obtained, a difference value between the initial wind sweeping angle and the first adjustment angle is calculated to obtain a first target wind sweeping angle, and the sum of the initial wind sweeping speed and the first adjustment speed is calculated to obtain a first target wind sweeping speed; under the condition that the photovoltaic air conditioner is started to perform an up-down wind sweeping mode and a left-right wind sweeping mode, a second adjustment angle and a second adjustment speed are obtained, a difference value between the initial wind sweeping angle and the second adjustment angle is calculated to obtain a second target wind sweeping angle, and a sum of the initial wind sweeping speed and the second adjustment speed is calculated to obtain a second target wind sweeping speed, wherein the first adjustment angle is smaller than the second adjustment angle, and the first adjustment speed is smaller than the second adjustment speed. According to the method, the target wind sweeping angle and the target wind sweeping speed are calculated according to different adjusting angles and adjusting speeds under the two conditions, so that the air conditioner can be controlled according to different conditions.

Specifically, when the air conditioner system is set at the outer ring temperature T ₀, the running frequency is Z ₀, the rotating speed of the inner fan is N ₀, the initial wind sweeping angle W ₁ of the upper and lower wind sweeping, the wind sweeping speed V ₁, the initial wind sweeping angle W ₂ of the left and right wind sweeping and the wind sweeping speed V ₂, and when the air conditioner system is normally running, the rotating speed fluctuation condition of the inner fan of the system is monitored at any moment, so that the time is kept in the rotating speed range of (N ₀ +/-30) r and N _n+1-N_n < 15 r: the method comprises the steps that the target rotating speed of a system is monitored once every second at the moment of the system, and is recorded as N ₁、N₂、N₃...N_n, when the Nn+1-Nn of the system is detected to be larger than 15r for the first time, the rotating speed regulation mode of the system is still regulated normally, if the internal machine is only started to sweep wind up and down or sweep wind left and right at the moment, the first regulating angle can be 15 degrees, the rotating speed regulation mode of the system is still regulated normally, the system regulates the internal machine sweeping wind angle to W ₁ -15 degrees or W ₂ -15 degrees for the first time, the first regulating speed is assumed to be V ₀, and the first regulating speed is regulated to V ₁-V₀ or V ₂-V₀; at this time, if the inner machine is opened up and down and left and right to sweep wind simultaneously, the rotational speed of the inner machine is more difficult to control due to the mutual influence of the up and down and left and right wind sweeping simultaneously, at this time, the initial wind sweeping angle is directly adjusted to the minimum value, namely, the second adjusting angle can be 25 degrees, the second adjusting speed is recorded as V ₃, and the initial wind sweeping angle is adjusted to the slowest speed (namely, the up and down wind sweeping angle is W ₁ -25 degrees, the speed is V ₁- V₃, the left and right wind sweeping angle is W ₂ -25 degrees, and the speed is V ₂- V₃).

In some alternative embodiments, the step S203 may be implemented by: controlling the wind sweeping plate of the photovoltaic air conditioner to be at the first target wind sweeping angle and the first target wind sweeping speed under the condition that the photovoltaic air conditioner is started in the up-down wind sweeping mode or in the left-right wind sweeping mode; and controlling the wind sweeping plate of the photovoltaic air conditioner to be at the second target wind sweeping angle and the second target wind sweeping speed under the condition that the photovoltaic air conditioner is started in the up-down wind sweeping mode and the left-right wind sweeping mode. Under the two different conditions, the method controls the wind sweeping angle and the wind sweeping speed of the wind sweeping plate to be the first target wind sweeping angle or the second target wind sweeping angle, so that the rotation speed of the inner fan of the air conditioner can be controlled to be stable according to actual conditions.

In the specific implementation process, after the first target wind sweeping angle, the first target wind sweeping speed, the second target wind sweeping angle and the second target wind sweeping speed are calculated in the steps, under the condition that only up-down or left-right wind sweeping is started and up-down or left-right wind sweeping is started at the same time, the wind sweeping plate of the air conditioner is controlled to be the first target wind sweeping angle, the first target wind sweeping speed, the second target wind sweeping angle and the second target wind sweeping speed respectively, so that the rotating speed of the inner fan is controlled to be stable under different conditions respectively, and then the following detection is carried out.

In order to continuously detect whether the inner fan tends to be stable, after controlling the wind sweeping angle of the wind sweeping plate to be the target wind sweeping angle and the wind sweeping speed of the wind sweeping plate to be the target wind sweeping angle in the step S203, the method may further include the following steps: step S2031: a calculation step of detecting the rotation speed of the inner fan according to a second preset time interval to obtain a second inner fan rotation speed corresponding to each second sampling time, and calculating the difference value of the second inner fan rotation speeds corresponding to two adjacent second sampling times, wherein the second preset time interval is smaller than the first preset time interval; step S2032: and controlling the photovoltaic air conditioner according to the difference value of the rotating speeds of the second inner fans at the two adjacent second sampling moments. After the wind sweeping angle and the wind sweeping speed of the wind sweeping plate of the air conditioner are controlled to be the target wind sweeping angle and the target wind sweeping speed, the method continues to detect the rotating speed of the inner fan according to a second time interval, and continues to determine whether the rotating speed of the inner fan is stable or not according to the difference value of the rotating speeds of the inner fans at two adjacent sampling moments, and further control is carried out.

In the specific application process, after the angle and the speed are adjusted, the rotation speed is monitored and adjusted to be monitored once every a second preset time interval, which can be 0.5s, and the air conditioner is still controlled according to the value of N _n+1-N_n, so that N _n+1-N_n is smaller than 15r.

In some alternative embodiments, step S2032 may be implemented by: an acquisition step of acquiring a third adjustment angle and a third adjustment speed when the absolute value of the difference value of the rotation speeds of the second inner fans corresponding to two adjacent second sampling moments is larger than the rotation speed threshold under the condition that the photovoltaic air conditioner is in an up-down wind sweeping mode or in a left-right wind sweeping mode, wherein the third adjustment angle is larger than the first adjustment angle, and the third adjustment speed is larger than the first adjustment speed; a control step of calculating a difference value between the first target wind sweeping angle and the third adjustment angle to obtain a third target wind sweeping angle, calculating a sum of the first target wind sweeping speed and the third adjustment speed to obtain a third target wind sweeping angle, and controlling the wind sweeping plate of the photovoltaic air conditioner to be the third target wind sweeping angle and the third target wind sweeping angle; and repeating the calculating step, the acquiring step and the controlling step at least once in sequence until the absolute value of the difference value of the second inner fan speeds corresponding to the two adjacent second sampling moments is smaller than or equal to the speed threshold, and continuously detecting the inner fan speed of the photovoltaic air conditioner according to the first preset time interval when the absolute value of the difference value of the second inner fan speeds corresponding to the two adjacent second sampling moments is smaller than or equal to the speed threshold. The method continues to control the photovoltaic air conditioner according to the difference value of the rotating speeds of the inner fans at two adjacent sampling moments, so that after the air conditioner is adjusted, whether the adjusting effect, namely the rotating speed of the inner fan is stable in area or not can be determined, and the method further comprises the step of controlling.

Specifically, if no rotation speed fluctuation is greater than 15r after 1min, the system rotation speed monitoring is restored to one time per second, if the rotation speed fluctuation still occurs with N _n+1-N_n > 15r in the above process, the angle and speed of the wind sweeping up and down or left and right are reduced again, that is, a third adjustment angle (25 ° or V ₃) and a third adjustment speed (V ₃) are obtained, the third target wind sweeping angle must not be less than W ₁-25°/W₂ -25 °, and the third target wind sweeping speed must not be less than V ₁-V₃/V₂-V₃ until the rotation speed fluctuation is less than 15r. The present application is not limited to the values of the respective adjustment angles and the respective adjustment speeds.

In order to further control the rotation speed of the inner fan to be stable, the step S2032 may be further implemented by: under the condition that the photovoltaic air conditioner is started in an up-down wind sweeping mode and a left-right wind sweeping mode, continuously detecting the rotating speed of the inner fan of the photovoltaic air conditioner according to the first preset time interval under the condition that the absolute value of the difference value of the rotating speeds of the second inner fans corresponding to two adjacent second sampling moments is smaller than or equal to the rotating speed threshold; and controlling the photovoltaic air conditioner according to a proportional-integral controller under the condition that the absolute value of the difference value of the rotating speeds of the second inner fans corresponding to the two adjacent second sampling moments is larger than the rotating speed threshold value. According to the method, under the condition that the rotating speed of the inner fan is stable, the rotating speed of the inner fan is detected according to the first time interval, and under the condition that the rotating speed of the inner fan is unstable, the photovoltaic air conditioner is controlled according to the proportional-integral controller, so that the rotating speed of the inner fan can be stable and kept stable.

In the specific implementation process, when the absolute value of the difference value of the rotating speeds of the second inner fans corresponding to two adjacent second sampling moments is smaller than or equal to the rotating speed threshold value, the rotating speed of the inner fans is indicated to meet the target that the difference between the two adjacent sampling moments is smaller than 15r, so that the inner fans are stable, and the second time interval monitoring is changed into the first time interval monitoring; and if the rotating speed of the inner fan still does not meet the stable condition, controlling the rotating speed of the inner fan by using a PID controller.

In some alternative embodiments, the photovoltaic air conditioner is controlled according to the proportional-integral controller, and the control method can be implemented by the following steps: acquiring a target value of the rotating speed of the inner fan, and detecting an actual value of the rotating speed of the inner fan; calculating the difference between the target value and the actual value to obtain a rotation speed error, and calculating the rotation speed error through a proportional integral controller to obtain a rotation speed correction; and calculating the difference between the actual value and the rotational speed correction amount to obtain a target rotational speed, and controlling the rotational speed of the inner fan of the photovoltaic air conditioner to be the target rotational speed. According to the method, the rotating speed of the inner fan is controlled through the proportional-integral controller, so that the control is continuously performed according to the proportional-integral controller under the condition that the rotating speed of the inner fan cannot be stabilized in the control mode, and the rotating speed of the inner fan is stabilized.

Specifically, the target value of the rotation speed of the inner fan is set as Nt, the actual rotation speed Na of the inner fan is obtained through a stroboscope or a rotation speed sensor, the rotation speed error e=nt-Na is calculated, the controller calculates the correction u according to the rotation speed error, and the formula of the proportional-integral controller can be adopted as follows: Where Kp, ki, kd are proportional, integral, and derivative coefficients, respectively, +. edt represents the integral of the rotational speed error, and de/dt represents the derivative of the rotational speed error. The controller output correction u is applied to the inner fan control loop, and the control precision is adjusted to stabilize the rotating speed and solve the problem of uneven air outlet caused by fluctuation of the rotating speed.

In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the control method of the photovoltaic air conditioner of the present application will be described in detail below with reference to specific embodiments.

The embodiment relates to a specific control method of a photovoltaic air conditioner, fig. 2 shows a schematic structural diagram of a photovoltaic air conditioning system, and the photovoltaic system and a commercial power system supply power to the air conditioning system, including the following steps:

Step S1: when the air conditioning system operates normally, the outer ring temperature T ₀ of the air conditioning system is assumed, the operating frequency is Z ₀, the rotating speed of the inner fan is N ₀, the initial wind sweeping angle W ₁ of upper and lower wind sweeping and the wind sweeping angle V ₁ of left and right wind sweeping are W ₂, the wind sweeping speed is V ₂, the rotating speed fluctuation condition of the inner fan of the system is monitored at all times, the time is kept in the rotating speed range of N ₀ +/-30 r and N _n+1-N_n < 15r, N represents the sampling time of the rotating speed of the inner fan, and the target rotating speed of the system is monitored once per second (first preset time interval) at the time of the system, and is recorded as N ₁、N₂、N₃...N_n;

Step S2: when N _n+1-N_n of the system is detected to be more than 15 for the first time, if the inner fan is only started to sweep air up and down or only started to sweep air left and right at the moment, the inner fan sweeping air angle is adjusted to be W ₁ -15 degrees or W ₂ -15 degrees (a first adjusting angle is 15 degrees) and V ₁- V₀ or V ₂- V₀ (a first adjusting speed is V ₀), the speed of the inner fan is monitored once every 0.5 seconds (a second preset time interval) after adjustment, N _n+1-N_n is ensured to be less than 15, if no phenomenon that the speed fluctuation is more than 15 occurs after 1min, the speed of the inner fan is monitored once every second (a first preset time interval), if the speed fluctuation still occurs N _n+1-N_n to be more than 15, the angle and speed of the upper and lower or left and right sweeping air are reduced again, the sweeping air angle is not less than W ₁-25°/W₂ -25 degrees (a third adjusting angle can be 25 degrees or can be other angles), the speed of the sweeping air is not less than V ₁- V₃/V₂- V₃ (a third adjusting speed V ₃), and the speed of the inner fan is not less than 15r;

Step S3: if the internal machine is started up, down, left and right wind sweeping simultaneously, the initial wind sweeping angle is adjusted to the minimum value, the initial wind sweeping angle is adjusted to the slowest speed, namely, the up and down wind sweeping angle is W ₁ -25 degrees (the second adjusting angle is a value larger than the first adjusting angle, for example, 25 degrees or other values), the speed is V ₁-V₄, the left and right wind sweeping angles W ₂ -25 degrees and the speed V ₂-V₄ are monitored once every 0.5 second (second preset time interval), and the rotating speed of the system is maintained within the rotating speed range of N _n+1-N_n < 15 r;
