Detailed Description
In order to make the purpose, features and advantages of the present invention more obvious and understandable, 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, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
An embodiment of the present invention provides a method for controlling an air conditioner, and referring to fig. 1, the method includes step S1: and acquiring the pressure at the wind shielding panel of the air conditioner in real time, and controlling the running state of the air conditioner according to the change of the pressure.
In one possible manner of this embodiment, the controlling the operation state of the air conditioner according to the change of the pressure includes: and judging whether the pressure is gradually reduced or not within a first preset time, and if so, reducing the rotating speed of the wind wheel. According to the pressure variation trend, the rotating speed of the wind wheel is adjusted, prejudgment is made in advance, and the condition that the rotating speed is too high and cannot be stopped quickly when the wind shielding panel is completely opened is avoided.
It should be noted that the obtaining of the pressure at the wind shielding panel of the air conditioner means obtaining a pressure value of a side of the wind shielding panel of the air conditioner facing the wind wheel. When the air conditioner wind shielding panel is in a normal state, the pressure value of the side, facing the wind wheel, of the air conditioner wind shielding panel is T1, when the air conditioner wind shielding panel is in an abnormal state, the pressure value of the side, facing the wind wheel, of the air conditioner wind shielding panel is T2, and T1 is larger than T2. That is, when the air conditioner wind shielding panel is unintentionally opened or dropped, the pressure value of the side of the air conditioner wind shielding panel facing the wind wheel is reduced. The wind shielding panel of the air conditioner and the base of the air conditioner enclose a cavity, and the wind wheel is arranged in the cavity. And in the normal operation process of the air conditioner, the air deflector of the air conditioner is opened, and air is discharged through the air outlet of the air conditioner. At the moment, wind generated by rotation of the wind wheel forms certain wind pressure in a cavity formed by the wind shielding panel of the air conditioner and the base of the air conditioner. When the air conditioner wind shielding panel is in an abnormal state, namely the air conditioner wind shielding panel is opened or dropped unintentionally, the air conditioner wind shielding panel is separated from or away from the base of the air conditioner, the condition of enclosing a cavity is avoided, and the wind pressure can be reduced or zero. In another feasible manner of this embodiment, the controlling the operation state of the air conditioner according to the change of the pressure further includes: judging whether the pressure is smaller than a first preset pressure threshold value or not, and if so, reducing the rotating speed of the wind wheel; or judging whether the pressure is smaller than a second preset pressure threshold value, if so, stopping rotating the wind wheel, and if not, keeping the rotation of the wind wheel, wherein the second preset pressure threshold value is smaller than the first preset pressure threshold value. According to the method, whether the pressure value of the wind wheel side of the wind shielding panel of the air conditioner is smaller than a preset value or not can be judged quickly, whether the wind shielding panel of the air conditioner is in an abnormal state or not can be judged, and whether the wind shielding panel of the air conditioner needs to be shut down or not is determined so as to protect the safety of a user. The first preset pressure threshold and the second preset pressure threshold may be pressure values when the wind shielding panel of the air conditioner is in a normal state.
When the pressure value at the wind shielding panel is still at a higher level, the opening of the wind shielding panel is not large, the rotation of the wind wheel can be reduced, and when the pressure value at the wind shielding panel is very low, the opening of the wind shielding panel is large, the rotation of the wind wheel is stopped immediately to ensure safety.
In a feasible manner of the embodiment of the present invention, the number of the preset pressure thresholds is multiple, and the preset pressure thresholds are different according to different rotation speeds of the wind wheel. For example, the preset pressure threshold is TS1 when the air conditioner is operated in the low wind range, TS2 when the air conditioner is operated in the medium wind range, and TS3 when the air conditioner is operated in the high wind range. Therefore, under different wind speeds, the generated wind pressures are different, and the judgment is carried out according to different preset pressure thresholds, so that the reliability of the judgment result is ensured, and the misjudgment is reduced.

Thus, the signal acquired by the pressure sensor is amplified by the first operational amplifier a1 and the second operational amplifier a 2. The first capacitor C1, the second capacitor C2, and the third capacitor C3 are used for filtering signals, and the third resistor R3 is used for balancing the positive input end and the negative input end of the second operational amplifier a 2.
In a possible manner, referring to fig. 4, the signal conditioning unit includes a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, a tenth resistor R10, an eleventh resistor R11, a fourth capacitor C4, a fifth capacitor C5, a sixth capacitor C6, a first diode D1, a second diode D2, a third diode D3, a fourth diode D4, a fifth diode D5, an NPN triode, and a 555 timer.
