and when the starting time length is less than a second preset time length, executing the step of obtaining the average temperature of the temperature detected by the first sampling frequency, wherein the first preset time length is greater than the second preset time length.
Referring to fig. 2, in an embodiment, the method for controlling the air conditioner includes the steps of:
step S10, acquiring the temperature detected by the temperature sensor at a first sampling frequency;
the first sampling frequency is a frequency at which the temperature sensor detects the temperature of the area in which the room is located within a preset time after the air conditioner is started, and may be set to 5 minutes/time (min/p), for example. In a preset time after the air conditioner is started, the temperature sensor of the action space of the air conditioner detects the temperature of the area where the temperature sensor is located at a first sampling frequency.
The number of the temperature sensors may be one or more in the present embodiment. Optionally, when the air conditioner has a plurality of sensors in the operating space, after the air conditioner is started, the plurality of sensors uniformly detect the temperature of the operating space of the air conditioner according to the first sampling frequency within a preset time.
Step S20, acquiring the target sampling frequency of the temperature sensor according to the temperature detected by the temperature sensor;
the target sampling frequency is the sampling frequency of the air conditioner for determining the indoor temperature according to the detected temperature. In order to avoid the problems that the temperature of the indoor environment is frequently detected by a temperature sensor when the indoor environment temperature is not stable in the initial stage of starting the air conditioner, so that the judgment accuracy of the air conditioner is reduced and the energy consumption of the temperature sensor is overlarge, the temperature sensor is arranged to detect the indoor environment temperature at a first sampling frequency, wherein the target sampling frequency is greater than the first sampling frequency.
Alternatively, when there is only one temperature sensor, the temperature detected by the temperature sensor is transmitted to the air conditioner after the air conditioner is started. And the air conditioner determines the target sampling frequency of the temperature sensor according to the acquired temperature. For example, after the air conditioner is started, the temperature sensor detects the indoor ambient temperature (25 ℃) at a first sampling frequency of 5 minutes/time, and transmits the indoor ambient temperature to the air conditioner. After receiving the temperature detected by the temperature sensor, the air conditioner compares the obtained temperature with the set temperature (28 ℃), and determines that the temperature of the current indoor environment is closer to the set temperature, and then determines that the target sampling frequency of the temperature sensor is 3 minutes/time; when the acquired indoor environment temperature is 22 ℃ (in the heating mode) and is lower than the set temperature, the temperature sensor is determined to continue to detect the temperature of the indoor environment according to the first sampling frequency, and no control operation is executed. The set temperature can be a default set temperature when the air conditioner leaves a factory, or can be set by a user according to specific use conditions.
Optionally, the temperature sensor in this embodiment may also be multiple. The air conditioner may determine the target sampling frequency according to the temperatures acquired by the plurality of temperature sensors, for example, as follows.
The number of the temperature sensors of the air conditioner acting space is 3. When the air conditioner acquires that the temperatures of areas where the 3 temperature sensors detect are 23 ℃, 25 ℃ and 26 ℃, respectively, the temperatures acquired by the three temperature sensors are determined to be less than the set temperature (28 ℃), and then the target sampling frequency of the three temperature sensors for detecting the indoor temperature is determined to be 3 minutes/time. When the temperatures of the areas detected by the temperature sensors are 26 ℃, 28 ℃ and 28 ℃, respectively, the target sampling frequency is set to be 1 minute/time, so that the air conditioner can acquire the indoor environment temperature and adjust the indoor environment temperature.
Alternatively, when a plurality of temperature sensors are provided in the operating space of the air conditioner, the air conditioner may be controlled to detect the indoor ambient temperature by controlling the temperature sensors of different regions at different target frequencies. For example, when the air conditioner operates in a heating mode, the temperatures detected by the first temperature sensor, the second temperature sensor and the third temperature sensor are respectively 26 ℃, 23 ℃ and 28 ℃ acquired at the first sampling frequency, and then it is determined that the temperature of the area where the second sensor is located needs to be adjusted by controlling the operation of the air deflector. Optionally, the air guide angle of the air guide plate is controlled so that the air outlet direction of the air conditioner is adjusted to the area where the sensor faces 23 ℃, so as to increase the temperature of the area where the second temperature sensor is located. Meanwhile, the second temperature sensor is controlled to detect the temperature of the area at the target sampling frequency of 1 minute/time, the first temperature sensor is controlled to detect the temperature of the area at the target sampling frequency of 2 minutes/time, and the third temperature sensor is controlled to detect the temperature of the area at the target sampling frequency of 2 minutes/time. The detection frequency of the temperature adjustment area is improved, the situation that the second temperature sensor of the air deflector can not timely acquire the temperature change of the area is avoided, and the temperature of each area of the action space can be timely acquired in the air conditioner adjustment process.
Step S30, sending the target sampling frequency to the temperature sensor.
When the air conditioner acquires the temperature sent by the temperature sensor at the first sampling frequency, the target sampling frequency of the temperature sensor is determined according to the acquired temperature, and the target sampling frequency is sent to the temperature sensor, so that the temperature sensor detects the temperature of the area according to the target sampling frequency after receiving the target sampling frequency.
In the present embodiment, the temperature sensor detects an indoor ambient temperature through a first sampling frequency and transmits the detected temperature to the air conditioner. After receiving the temperature detected by the temperature sensor, the air conditioner determines the target sampling frequency of the temperature sensor according to the received temperature and sends the determined target sampling frequency to the temperature sensor so as to control the temperature sensor to detect the temperature of the area according to the target sampling frequency. The detection frequency of the temperature sensor is adjusted in real time according to the temperature of the current indoor environment, and energy loss when the temperature sensor detects the temperature of the indoor environment in real time is reduced.
In another embodiment, as shown in fig. 3, on the basis of the embodiment shown in fig. 2, step S20 includes:
step S21, acquiring temperature difference of the temperature acquired by each temperature sensor, wherein at least two temperature sensors are arranged in the indoor environment of the air conditioner;
step S22, when the temperature difference is larger than or equal to the preset temperature difference, taking a second sampling frequency as the target sampling frequency;
and step S23, when the temperature difference is smaller than the preset temperature difference, taking a third sampling frequency as the target sampling frequency, wherein the second sampling frequency is greater than the third sampling frequency, and the third sampling frequency is greater than the first sampling frequency.
In this embodiment, there are at least two temperature sensors, and the air conditioner determines a target sampling frequency of the temperature sensors according to a temperature difference between temperatures of the at least two temperature sensors. Alternatively, in the embodiment, the temperature sensors are exemplified by a first temperature sensor and a second temperature sensor which are installed at opposite positions in the air conditioner operation space.
When the air conditioner acquires that the temperature of the first area detected by the first temperature sensor is 27 ℃, the temperature of the second area detected by the second temperature sensor is 22 ℃, the temperature difference between the first sensor and the second sensor is 5 ℃ (the temperature difference is determined by using the absolute value of the temperature subtraction between the two sensors, such as |27-22|), and is greater than the preset temperature difference by 2 ℃, then the frequency of the first temperature sensor and the second temperature sensor for detecting the temperature of the areas where the first temperature sensor and the second temperature sensor are located is determined, wherein the second sampling frequency can be set to be 1 minute/time.
The method comprises the steps that the temperature of a first area detected by a first temperature sensor is 28 ℃ when the air conditioner obtains, the temperature of a second area detected by a second temperature sensor is 27 ℃, the temperature difference between the first sensor and the second sensor is 1 ℃ (|27-28|), the temperature difference is smaller than a preset temperature difference by 2 ℃, the temperature of an action space of the air conditioner is determined to meet a temperature uniformity condition, a third sampling frequency is determined to be used as the frequency of the first temperature sensor and the second temperature sensor for detecting the temperature of the areas where the first temperature sensor and the second temperature sensor are located, and the third sampling frequency can be set to be 3 minutes/time.
In this embodiment, the temperature sensor through installing the effect space at the air conditioner acquires the temperature in place region, and then confirms the difference in temperature of the temperature that individual temperature sensor obtained, when the difference in temperature is greater than preset difference in temperature, control temperature sensor gathers the temperature in place region with second sampling frequency, when the difference in temperature is less than preset difference in temperature, control temperature sensor gathers the temperature in place region with third sampling frequency, wherein third sampling frequency is less than second sampling frequency. The frequency of collecting the indoor environment temperature by the temperature sensor can be reduced when the temperature of the indoor environment reaches the uniform temperature, and the frequency of collecting the indoor environment temperature by the temperature sensor is relatively improved when the temperature of the indoor environment is not uniform. Under the condition through at different indoor ambient temperature, control temperature sensor detects its regional temperature in place with different frequencies, has improved temperature sensor and has detected indoor ambient temperature's intellectuality, compares in real-time detection indoor ambient temperature, has reduced temperature sensor and has acquireed indoor ambient temperature's frequency, has reduced temperature sensor's energy loss.
Optionally, in this embodiment, after the air conditioner obtains a temperature difference between the temperatures of the first temperature sensor and the second temperature sensor and determines that the temperature difference is smaller than a preset temperature difference, the first temperature sensor and the second temperature sensor are controlled to detect the temperature of the indoor environment at a third sampling frequency and a frequency of 3 minutes/time. And calculating the starting time length of the air conditioner (the time length after the air conditioner is started), and when the starting time length is determined to be greater than or equal to the first preset time length, sending a sleep instruction to the temperature sensor to control the temperature sensor to enter a sleep state. For example, the first preset time period may be set to 60 minutes, and the first and second temperature sensors detect the temperature of the indoor environment at the third sampling frequency (3 minutes/time) and transmit to the air conditioner. After the air conditioner receives the temperatures sent by the first temperature sensor and the second temperature sensor, when the temperature of the indoor environment is determined to be uniform according to the temperature difference of the temperatures, the temperature sensor is controlled to continue to detect the temperature of the indoor environment at the third sampling frequency, and a sleep instruction is sent to the temperature sensor until the starting duration of the air conditioner reaches 60 minutes, so that the temperature sensor is controlled to enter a sleep state.
And when the starting time of the air conditioner does not reach the first preset time, controlling the temperature sensor to sample and detect the indoor environment temperature at the third sampling frequency, and accurately determining whether the temperature of the action space is maintained in a uniform state or not by determining the temperature of each area of the action space of the air conditioner for multiple times.
Optionally, in this embodiment, when the air conditioner controls the temperature sensor to detect the temperature of the indoor environment at the second sampling frequency, and when the start duration of the air conditioner is greater than or equal to the first preset duration, it is determined that the temperature of the indoor environment, which cannot be currently adjusted by the air conditioner, reaches uniform temperature, and a sleep command is sent to the temperature sensor to control the temperature sensor to stop detecting. The energy loss caused by the fact that the temperature sensor continues to detect the indoor environment temperature under the condition that the air conditioner cannot accurately adjust the indoor environment temperature is avoided.
In this embodiment, when it is determined that the starting duration of the temperature sensors detecting the indoor environment temperature at the third sampling frequency is greater than or equal to the first preset duration, a sleep command is sent to each of the temperature sensors to control each of the temperature sensors to stop detecting the indoor environment temperature and enter the sleep mode. After the temperature of the indoor environment is determined to be kept uniform, the temperature sensor is controlled to stop detecting the temperature of the indoor environment, and energy loss of the temperature sensor is greatly reduced.
In addition, referring to fig. 4, fig. 4 is a schematic flow chart of adjusting the air deflector of the air conditioner according to the present application. When the temperature difference is greater than or equal to a preset temperature difference, after the step of taking a second sampling frequency as the target sampling frequency, the method further comprises the following steps:
step S40 of comparing the temperatures detected by the respective temperature sensors;
step S50, adjusting the angle of the air deflector of the air conditioner according to the comparison result and the position information of each temperature sensor; or;
and step S60, adjusting the angle of the air deflector of the air conditioner according to the comparison result and the air guide angle associated with each temperature sensor.
In this embodiment, when the air conditioner uses the second sampling frequency as the target sampling frequency, that is, when it is determined that the temperature of the indoor environment is not uniform enough at this time through the difference between the temperatures obtained by the temperature sensors, the operation parameters of the air conditioner need to be adjusted to achieve uniform temperature of the indoor environment.
Optionally, in this embodiment, after the temperatures of different areas are obtained by the temperature sensor, the magnitudes of the temperatures are compared, and then the operation parameters of the air conditioner that need to be adjusted are determined. For example, when the air conditioner is in the cooling mode, the temperature detected by the temperature sensor of the first zone is 28 ℃ and the temperature detected by the temperature sensor of the second zone is 24 ℃. And determining to adjust the temperature of the first area, adjusting the angle of the air deflector to be the maximum angle, conveying a low-temperature refrigerant to the first area, and reducing the temperature of the first area.
Optionally, after the air conditioner determines the angle of the air deflector for conveying the low-temperature refrigerant to the first area, the rotating speed of an indoor fan of the air conditioner can be adjusted according to the angle of the air deflector. For example, when the angle of the air deflector of the air conditioner is 40 °, the rotation speed of the indoor fan is controlled to be increased by 100r/min (revolutions per minute), and when the angle of the air deflector of the air conditioner is 60 °, the rotation speed of the indoor fan is controlled to be increased by 200 revolutions per minute.
Optionally, in this embodiment, the angle between the temperature sensor and the air deflector is associated, for example, when the air conditioner is in a cooling mode, the temperature detected by the temperature sensor in the first area is 29 degrees celsius, the air deflector of the air conditioner associated with the currently obtained angle is determined to be 50 degrees, and the air deflector of the large sealing plate of the air conditioner is controlled to be adjusted to 50 degrees; and when the temperature of the first area detected by the temperature sensor is 28 ℃, determining that the air deflector of the air conditioner associated with the currently obtained angle is 40 ℃, and controlling the air deflector of the large air conditioner sealing plate to adjust to 40 ℃.
It can be understood that, when the air conditioner is in the heating mode, the obtained temperature sensors can also be used for detecting the temperature of the indoor environment to adjust the angle of the air deflector and the rotating speed of the fan.
The temperature of the indoor environment is adjusted by controlling the angle of the air deflector and the indoor fan of the air conditioner in a cooperative mode, so that the speed of enabling the temperature of the indoor environment to reach the temperature uniformity is improved, the time of detecting the temperature of the indoor environment by the temperature sensor at the second sampling frequency is shortened, and the energy loss of the temperature sensor is reduced.
Based on the first embodiment, the present application proposes yet another embodiment.
After the step of acquiring the temperature detected by the temperature sensor at the first sampling frequency, the method further comprises the following steps:
step S01, obtaining the average temperature of the temperatures detected by the temperature sensor at the first sampling frequency;
step S02, when the average temperature is equal to the preset temperature, determining whether the air conditioner starts a temperature uniform mode;
and step S03, when the air conditioner is determined not to start the temperature uniformity mode, sending a sleep instruction to the temperature sensor.
The temperature uniformity mode is a mode in which the air conditioner controls the temperature of each area in the room to be in a uniform state.
In this embodiment, after the air conditioner is started, the start time of the air conditioner is obtained, and when the start time of the air conditioner is less than a second preset time (for example, 20 minutes), the air conditioner receives the temperature sensor to obtain the indoor temperature at the first frequency, and calculates the average temperature according to the obtained temperature. When the average temperature reaches the preset temperature, whether a temperature uniformity mode is started or not is determined so as to judge whether a target sampling frequency needs to be determined according to the temperature detected by the temperature sensor at the first sampling frequency or not. And when the average value of the acquired temperatures does not reach the preset temperature, determining and controlling the temperature sensor to continuously detect the indoor temperature at the first sampling frequency.
Optionally, when the air conditioner determines that the average temperature reaches the preset temperature and the indoor temperature uniformity mode is currently started, the step of determining the target sampling frequency according to the temperature detected by the first sampling frequency is executed, when it is determined that the indoor temperature uniformity mode is not started, a sleep instruction is sent to the temperature sensor to reduce power consumption of the temperature sensor for detecting the indoor temperature, when the air conditioner receives the instruction for starting the temperature uniformity mode, the temperature sensor is awakened to detect the indoor temperature, the temperature sensor detects the indoor temperature and sends the temperature detected by the temperature sensor to the air conditioner, and then the step S20 is executed.
In this embodiment, the air conditioner calculates an average temperature of the temperatures according to the temperatures detected by the acquired temperature sensors, and detects whether the air conditioner starts the temperature equalization mode when the average temperature is equal to a preset temperature. The target frequency of the temperature sensor is determined according to the obtained temperature under the condition that the indoor temperature reaches the preset temperature and the air conditioner starts a temperature uniform mode, and the accuracy of the air conditioner in determining the target frequency is improved.
Referring to fig. 5, fig. 5 is a schematic view of the inventive concept of the present application.
The method comprises the following steps: starting an air conditioner;
step two: bluetooth temperature sensor received signal, record time t (start duration):
1. when t < tmin (the second preset time period tmin is preferably 20min), the temperature sensor detects the temperature of the indoor environment at the first sampling frequency a (a is preferably 5 minutes/time), and timing is continued; when the temperature reaches (TA + TB is 2 × Ts, wherein Ts is a preset temperature, and the value can be set by a user), entering a fourth step;
2. when t is more than or equal to tmin, entering the next judgment;
step three: judging whether the temperature is in a uniform mode:
1. when the temperature is not in the temperature uniform mode at present, the first acquisition frequency a of the sensor acquires the temperature of the indoor environment and sends the temperature to the air conditioner;
2. when the current mode is the 'temperature uniform mode', entering the next step;
step four: reading temperature values TA, TB of the sensor A, B, detecting a temperature uniformity deviation Δ T (Δ T | TA-TB |):
step five: and (3) judging whether the room temperature is uniform or not according to the delta T value, and whether air supply needs to be adjusted or not:
1. when delta T is less than m, the room temperature is uniform, the air conditioner does not need to be frequently adjusted, feedback signals are reduced to the air conditioner, and the temperature sensor feeds back one-time signals to the air conditioner when detecting the indoor temperature at a second sampling frequency b (b is preferably 3 minutes/time);
2. when the delta T is larger than or equal to m, the room temperature is not uniform, the air conditioner needs to adjust air supply, the sensor detects the temperature of the indoor environment in time and feeds the temperature back to the air conditioner, and the air conditioner guides the air deflector to adjust according to the obtained temperature. The sensor detects the indoor ambient temperature of the space where the air conditioner acts at a second sampling frequency c (c is preferably 1 minute/time) and sends the indoor ambient temperature to the air conditioner.
Step six: the temperature sensor detects the starting time t of the indoor temperature at the third sampling frequency, judges whether the air conditioner completes adjustment and is in a stable state:
1. when t1< tmax (the first preset time tmax is preferably 40min), returning to the third step;
2. when t1 is larger than or equal to tmax, the sensor A, B sleeps and stops feedback until the power-on awakening next time.
