Detailed Description
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example 1
As shown in fig. 1, it is a schematic structural diagram of the interrupt control method in this embodiment; the power-off control method comprises the following steps:
s1, detecting the state of an air conditioner power-off switch;
the power-off switch is positioned below a panel of the air conditioner, the power-off switch is associated with the panel of the indoor unit of the air conditioner, and the power-off switch is disconnected when the panel is detached or opened in a normal state; when the panel is closed, the power-off switch is closed. Therefore, when the power-off switch is in an off state, the panel can be explained to be in an open or detached state to a greater extent.
Specifically, the power-off switch is arranged between a lamp panel and a display box of the air conditioner, namely, two ends of the power-off switch are respectively connected with the lamp panel and the display box, and the power-off switch is pressed between the lamp panel and the display box through the display box, and is in a pressing state at the moment, the power-off switch is closed, and the air conditioner is electrified; when the display box is detached, the power-off switch is in a bouncing state, the power-off switch is disconnected, and the air conditioner is powered off. The lamp panel of the air conditioner is arranged on the electric control box, the power-off switch is connected with a control circuit in the electric control box of the air conditioner, and when the power-off switch is pressed, the control circuit in the electric control box is communicated with an external power supply, so that the air conditioner is powered on; when the power-off switch bounces, the control circuit in the electric control box is disconnected with the external power supply, so that the air conditioner is powered off. The display box of the air conditioner is fixed on the panel, when the panel is closed, the display box presses the power-off switch between the lamp panel and the display box, namely between the panel and the lamp panel, and the power-off switch is in a pressed state at the moment; when opening or dismantling the panel, the display box disappears to the press effort of power off switch, and the display box no longer presses power off switch, and power off switch is in the bounce-up state this moment.
S2, detecting the illumination intensity of the inner side of the mounting position of the air conditioner panel;
when the panel is detached or opened, the inner side of the mounting position of the air conditioner panel is in an exposed state, and the illumination is strong; when the panel is closed, the inner side of the mounting position of the air conditioner panel is shielded by the panel, and the illumination is weak. Therefore, when the light on the inner side of the panel installation position is strong, the panel can be explained to be in an open or detached state to a large extent.
S3, performing power-off protection on the air conditioner according to the state of the power-off switch and the illumination intensity;
wherein, it includes to carry out power-off protection to the air conditioner: and controlling the load of the air conditioner to be closed, wherein the load comprises an inner fan, a swing motor, an electric heating device, a negative ion generating device, an outer machine power supply and the like. After the air conditioner load is closed, the air conditioner is shut down by default, the air conditioner control instruction sent by the remote controller or the APP cannot be executed, and the potential safety hazard cannot exist when the user unpicks and washes the air conditioner.
Further, step S3 includes:
s31, if the power-off switch is in an off state and the illumination intensity is greater than a first light intensity threshold value, performing power-off protection on the air conditioner;
the first light intensity threshold is a set fixed value and can be adjusted according to the environment where the air conditioner is located.
In this embodiment, when the power-off switch is in the off state, the panel can be described as being in the open or detached state to a greater extent, but if the power-off switch is in the abnormal state, the state of the panel is determined by detecting the state of the power-off switch alone, and there is a possibility that erroneous determination occurs.
Therefore, the power-off control method in the embodiment can timely perform power-off protection on the air conditioner when the user unpicks and washes the air conditioner; and the opening or detaching state of the panel is judged by simultaneously detecting the state of the power-off switch and the illumination intensity, so that the accuracy of judging the opening or detaching state of the panel is improved, the misjudgment is avoided, and the normal operation of the air conditioner is ensured.
Further, in step S31, while performing power-off protection on the air conditioner, the method further includes:
and controlling a buzzer of the air conditioner to continuously sound and/or controlling a display screen of the air conditioner to display a fault code B and twinkle.
Wherein, the buzzer of the air conditioner is controlled to continuously sound, and a user can be reminded to pull out the power line of the air conditioner. The display screen of the control air conditioner displays the fault code B and flickers, so that a user can be reminded of opening or detaching the air conditioner panel, and the user is reminded of pulling out the power line of the air conditioner.
Further, step S3 further includes:
s32, if the power-off switch is in an off state and the illumination intensity is smaller than the second light intensity threshold value, or the power-off switch is in an on state and the illumination intensity is larger than the first light intensity threshold value, performing power-off protection on the air conditioner.
Step S31 is a parallel step with step S32.
The second light intensity threshold value is a set fixed value and can be adjusted according to the environment of the air conditioner; the second light intensity threshold is not greater than the first light intensity threshold.
Wherein, if the air conditioner detects that the function of illumination intensity is normal:
when the power-off switch is in a normal state, if the power-off switch is detected to be in an off state, the air conditioner panel is in an open or detached state, and the illumination intensity is certainly greater than a first light intensity threshold value; if the illumination intensity is detected to be smaller than a second light intensity threshold value, the power-off switch is in an abnormal state;
when the power-off switch is in a normal state, if the power-off switch is detected to be in a closed state, the power-off switch represents that the air conditioner panel is in the closed state, and the illumination intensity is necessarily smaller than a second light intensity threshold value; if the illumination intensity is detected to be larger than the second light intensity threshold value, the power-off switch is in an abnormal state.
Similarly, if the function of the power-off switch is normal:
if the power-off switch is detected to be in an off state, the air conditioner panel is in an open or detached state, and the illumination intensity is certainly greater than a first light intensity threshold value; if the detected illumination intensity is smaller than a second light intensity threshold value, indicating that the function of the air conditioner for detecting the illumination intensity is abnormal;
when the power-off switch is in a normal state, if the power-off switch is detected to be in a closed state, the power-off switch represents that the air conditioner panel is in the closed state, and the illumination intensity is necessarily smaller than a second light intensity threshold value; and if the detected light intensity is larger than the second light intensity threshold value, indicating that the function of the air conditioner for detecting the light intensity is abnormal.
As can be seen from the above analysis, if the power-off switch is in the off state and the illumination intensity is less than the second light intensity threshold, or the power-off switch is in the on state and the illumination intensity is greater than the first light intensity threshold, it represents that at least one of the function of the power-off switch and the function of the air conditioner for detecting the illumination intensity is in an abnormal state, and the power-off protection function of the air conditioner is abnormal.
Therefore, through the steps, the power-off control method in the embodiment can also detect the abnormal state of the power-off protection function of the air conditioner, so that the fault of the air conditioner can be found in time, and the protection of the air conditioner is enhanced.
Further, in step S32, the method for protecting an air conditioner from power failure includes:
and controlling a buzzer of the air conditioner to continuously sound and/or controlling a display screen of the air conditioner to display the fault code A and twinkle.
Wherein, the buzzer of the air conditioner is controlled to continuously sound, and a user can be reminded to pull out the power line of the air conditioner. The display screen of the air conditioner is controlled to display the fault code A and flicker, so that the user can be reminded of the abnormal power-off protection function of the air conditioner, and the user is reminded of reporting and repairing the air conditioner.
Further, the power-off control method further includes:
and S4, if the power-off switch is in a closed state and the illumination intensity is smaller than a second light intensity threshold value, controlling the air conditioner to recover normal operation.
And if the power-off switch is in a closed state and the illumination intensity is smaller than a second light intensity threshold value, the user takes the place that the air conditioner is disassembled and washed and the panel is installed or the user maintains the air conditioner and installs the panel.
Therefore, through the steps, the power failure control method in the embodiment can control the air conditioner to recover to normal operation in time after the user unpicks and washes the air conditioner and installs the panel or after the user maintains the air conditioner and installs the panel; and the closed state of the panel is judged by simultaneously detecting the state of the power-off switch and the illumination intensity, so that the accuracy of judging the closed state of the panel is improved, the misjudgment is avoided, and the normal operation of the air conditioner is ensured.
Further, as shown in fig. 2, the power outage control method further includes:
s5, detecting the state of an air conditioner emergency switch key;
the emergency switch key is positioned in the air conditioner and can be manually operated after the air conditioner panel is opened or detached. The emergency switch button can control the on-off of the air conditioner.
S6, if the emergency switch key is pressed, memorizing the pressing times;
if the emergency switch key is not pressed down, the air conditioner is defaulted to continue to be kept in the shutdown state after the air conditioner is unpicked and washed by a user and the panel is closed, and the air conditioner can normally receive and execute the command of the remote controller or the APP after the panel is closed. If the panel is in an open or detached state and the emergency switch key is manually pressed, the air conditioner receives the key signal, memorizes the key signal times but does not execute the key signal.
S7, if the pressing times are odd, controlling the air conditioner to start after the air conditioner panel is closed; and if the pressing times are even, controlling the air conditioner to keep a shutdown state after the air conditioner panel is closed.
Therefore, after the user is emptied after the disassembly and washing, the emergency switch button can be pressed for an even number of times, and the air conditioner is automatically started after the panel is installed; when a user maintains the air conditioner, the emergency switch button can be pressed for even times, and the air conditioner is automatically started after the air conditioner is maintained and the panel is installed. Like this, when the air conditioner remote controller loses or APP operates inconveniently, the user accessible emergency switch button control air conditioner start.
Therefore, when a user maintains the air conditioner, the user can press the emergency switch button for even times or odd times, and after the air conditioner is maintained and the panel is installed, whether the air conditioner is in a shutdown state or is started is observed. Like this, whether the user of being convenient for verifies the air conditioner after having maintained the air conditioner normal, need not remote controller or APP operation, it is fast to verify.

When the emergency switch detection pin P2 of the controller 30 receives the low level signal once, the controller 30 memorizes the number of times of pressing. It should be noted that the above-mentioned high-low level control logic is only an example, and the conversion of the emergency switch circuit 40 naturally causes the conversion of the above-mentioned control logic, and cannot form a limitation on the power failure control device.
