The intelligent eye is usually assembled on an indoor unit of the air conditioner, is responsible for searching the use position of a user and controls the wind direction, the wind power and the temperature according to the requirements of a control unit or a cloud processor. It is the most closely related part of the air conditioning system to the user and thus determines the comfort experience of the user. However, due to the limitation of the recognition angle range, accuracy and data acquisition speed, the smart eye can only recognize the moving range of the user in a state that the user is nearly still. Meanwhile, the use of the intelligent eyes greatly improves the selling price of air conditioner products, the average service life of the air conditioner products as large durable consumer goods is about 10 years, and the number of the air conditioners in the whole country is about 6 hundred million at present according to the data of the national statistical bureau. There is a significant economic cost to the user to replace their existing air conditioners in the home for the purpose of experiencing smart control, and it is not practical to replace their existing air conditioners with all users nationwide.
In the existing non-intelligent air conditioner temperature control technology, a user needs to set an air conditioner air outlet temperature Ts, and after the air conditioner temperature is set, the air conditioner is stopped when the difference value between an indoor temperature value T1 measured by a temperature sensing probe of an indoor unit and the set air conditioner air outlet temperature Ts reaches a certain value. When the difference value of the two values is lower than a certain value, the air conditioner can be started again. Thus, the indoor temperature T1 is as close as possible to the set air conditioner outlet air temperature Ts. However, the sensor for measuring the indoor temperature T1 is usually arranged on the air inlet or the wire controller of the air conditioner and is not arranged on the air inlet or the wire controller of the air conditionerIs the temperature T (theta) of the location of the userx,rx) Therefore, when the indoor temperature T1 reaches the set air-conditioning outlet temperature Ts, the temperature T (θ) of the user is often the same as the set temperature T (T _x,rx) The difference between the indoor temperature and the set value of the air-out temperature of the air conditioner is too far, and when the air conditioner is stopped, the indoor temperature does not meet the comfort requirement of a user, and refrigeration or heating is required to be continued.
The control of the air supply direction and the wind power of the existing non-intelligent air conditioner basically depends on that a user respectively clicks and selects vertical air swinging and horizontal air swinging on a remote controller or an APP, and the temperature of an air outlet is set according to experience. After the up-and-down swinging air needs to be clicked, the position state of the air outlet guide vane of the air conditioner is checked manually, and whether the outlet air blows to the use position of a user or not is sensed. After the air conditioner is clicked step by step, the position state of the air outlet guide vane of the air conditioner is changed, and finally a user can sense air blowing of the air conditioner. However, the user needs to judge whether the temperature of the air reaching the user position meets the comfort requirement of the user, and if the temperature of the air outlet of the air conditioner is not met, the air outlet temperature of the air conditioner is reset until the comfortable temperature satisfied by the user is reached.

Referring to fig. 2, the user marks and uploads the coordinate points to the cloud processing data, so as to obtain an outer contour curve and a house plane structure diagram of the house, and obtain the specific position of the air conditioner in the house.
Specifically, after the air conditioner is installed, a user needs to mark the air conditioner position on the mobile phone app, and input the installation height of the air conditioner and the side length of the room, so that the spatial position of the air conditioner in the room is determined. The mobile phone automatically divides the room with the input size into a plurality of grids according to the area average.
In addition, the user may mark the user's current location information on the app.
S12: and acquiring a temperature adjustment correction coefficient of the cell to which the current position information belongs, wherein the temperature adjustment correction coefficient is determined according to the comfortable temperature set for the cell by the user in the pre-calibration process.
The air conditioner control method provided by this embodiment may be referred to as a self-positioning adjustment stage of a user use stage, and in addition, the air conditioner control method may further include a calibration stage of comfort level of use of the air conditioner. And acquiring the temperature regulation correction coefficient of each unit cell in the calibration stage of the using comfort degree of the air conditioner.
Accordingly, referring to fig. 3, the method further comprises:
s10: and calibrating the temperature regulation correction coefficient of each cell obtained by dividing the room area.
Specifically, referring to fig. 4, the calibrating the temperature adjustment correction coefficient of each cell obtained by dividing the room area includes:
s41: and acquiring position information marked by the user when the user is located at the preset position corresponding to each preset position in the room area, and adjusting an air deflector of the air conditioner to supply air towards the user according to the position information.
For example, referring to fig. 2, after the surrounding contour of the house is obtained, a user can walk to 4 corners of the house and the middle positions of the two side walls of the air-conditioning outlet, and after the user is at a certain preset position, the user can mark the current position information and send the current position information to the system, so that the position information of the user is obtained, and the position information can be used respectively (θ)2,r2)…(θ7,r7) And (4) showing. After the air conditioner obtains the position information of the person, the air deflector can be adjusted to respectively face (theta)2,r2)…(θ7,r7) To supply air.
S42: receiving the set temperature sent by the user at the preset position, wherein the set temperature is set by the user according to the air supply feeling, and the latest set temperature meeting the rationality requirement is determined as a comfortable temperature to replace the set air outlet temperature Ts initially calculated by the system.
After the air conditioner supplies air towards the position of a person, the person can set corresponding set temperature corresponding to each preset position through self feeling.
The user can change the set temperature at different moments, the latest set temperature is usually determined as the comfortable temperature, however, the system can remove the unreasonable temperature, such as the higher or lower temperature, after receiving the set temperature sent by the user, and the latest set temperature meeting the rationality requirement is determined as the comfortable temperature, considering the temperature which the user may set randomly. The specific higher or lower value can be determined according to actual conditions.
It is assumed that the set comfort temperatures are denoted by T2, …, T7, respectively. Generally, the temperature values of different areas where the air-conditioning outlet air reaches are different due to different use positions of users due to different indoor home furnishings and distances. The user needs to reset the outlet air temperature to make the air temperature sent to the position of the user reach the temperature which the user feels comfortable, namely reach the comfortable temperature Ts preset by the system. The set comfort temperatures for the different zones are different and the comfort temperature experienced by the user is the same, e.g., T2, …, T7 are different, but after the user sets T2, …, T7, the temperature sensed at the location is substantially the same comfort value, which is equal to the value of the comfort temperature Ts preset by the system.
S43: and acquiring the measured temperature of the user at the preset position, and determining a temperature regulation correction coefficient corresponding to the preset position according to the measured temperature and the comfortable temperature.
The measured temperature can be obtained at each preset position through a temperature sensing probe of the air conditioner, and the temperature regulation correction coefficient of each preset position can be obtained according to the set comfortable temperature. For example, if the comfort temperature at a predetermined position is T2 and the measured temperature is T1, the temperature adjustment correction coefficient α (θ) corresponding to the predetermined position is2,r2) T2-T1. Similarly, temperature adjustment correction coefficients corresponding to other preset positions can be obtained: alpha (theta)3,r3)，…，α(θ7,r7). Generally speaking, the measured temperatures of different areas are different, so the temperature adjustment correction coefficients corresponding to different areas are also different.
S44: and determining the cell to which each preset position belongs, and determining the temperature regulation correction coefficient corresponding to the preset position as the temperature regulation correction coefficient of the cell to which the preset position belongs.
For example, (theta)2,r2) The cell belonging to is cell 2, the temperature adjustment correction coefficient of the cell is alpha (theta)2,r2)。
Optionally, the cell after the room area division further includes: the calibrating the temperature adjustment correction coefficient of each cell obtained by dividing the room area, except for the cells to which the preset position belongs, further includes:
and determining the temperature regulation correction coefficients of other cells according to the temperature regulation correction coefficient of the cell to which the preset position belongs.
For example, referring to fig. 2, the temperature adjustment correction coefficients of the cells 2, 4, 5, 7, 8, 10 may be obtained by locating a person at the cells 2, 4, 5, 7, 8, 10, and the temperature adjustment correction coefficients of the cells 3, 6, 9 may be obtained from the temperature adjustment correction coefficients of the cells 2, 4, 5, 7, 8, 10. The process can also be directly solved by a formula for predicting the average Vote (PMV) or realized by a neural network method process.
In addition, when the number of users is one and the activity range is in one cell, the cell to which the user belongs can be determined according to the position information of the user, and the temperature adjustment correction coefficient of the cell is obtained.
When the number of the users is at least two, and the activity areas of the at least two users occupy at least two cells, or when the number of the users is one and the activity area of the user occupies at least two cells, the obtaining of the temperature adjustment correction coefficient of the current cell includes:
acquiring a temperature regulation correction coefficient of each cell occupied by the user;
and according to a preset weighting algorithm, carrying out weighting operation on the temperature regulation correction coefficient of each cell occupied by the user, and determining the temperature regulation correction coefficient after weighting operation as the temperature regulation correction coefficient of the cell.
For example, the users are two, respectively located in cell 2 and cell 3, and the corresponding temperature adjustment correction coefficients are respectively α (θ)2,r2) And α (θ)3,r3) Then, can be aligned to alpha (theta)2,r2) And α (θ)3,r3) And after weighted averaging, obtaining a new temperature regulation correction coefficient, and determining the new temperature regulation correction coefficient as the adopted temperature regulation correction coefficient.
S13: and acquiring the measured temperature, and correcting the measured temperature according to the temperature regulation correction coefficient to obtain the corrected temperature.
The measured temperature can be detected by a temperature sensing probe arranged on the air conditioner.
Assuming that the measured temperature is represented by T1, the temperature adjustment correction coefficient is represented by α (θ)x,rx) The corrected temperature can be represented by T1+ alpha (theta)x,rx) And (4) showing.
S14: and controlling the air conditioner according to the current position information and the corrected temperature.
In one aspect, the air conditioner may be controlled to stop or start according to the corrected temperature.
In the conventional scheme, the control is directly performed according to the measured temperature and the set temperature, but in the embodiment, the corrected temperature is used for controlling the temperature. Specifically, see table 1, where the original shutdown and startup determination algorithm in table 1 is a conventional scheme, and the improved shutdown and startup determination algorithm is the algorithm adopted in this embodiment.

On the other hand, if the air conditioner can swing wind continuously according to the traditional control mode, the position which really needs to intensively use the air conditioner can not be effectively controlled by temperature, so that the comfort of people can be reduced, and a lot of energy waste can be caused. In the embodiment, the air guide plate can be controlled to blow air towards the user according to the position of the user, so that the comfort of the user is improved, and energy is saved.
By adopting the temperature adjustment correction coefficient, the wind outlet force and the wind volume can be gradually increased from near to far along the wind outlet direction. When the air supply direction is adjusted, the horizontal distance between a user and the air conditioner air outlet can be calculated to obtain the angle of the horizontal air deflector of the air conditioner air outlet, and the position of each horizontal area grid determines the swing angle of the vertical air deflector of the air conditioner air outlet.
In addition, the set temperature may be set by a user, or the air conditioner may give a recommended value, and the user determines the recommended value as the final set temperature, or the user may modify the recommended value and determine the modified temperature value as the final set temperature.
Wherein the recommended value can be determined according to the comfort value set by the user in the calibration stage, for example, the user is in (theta)2,r2) The comfort value set is T2 if the user is currently in the cell (θ)2,r2) To which cell the recommended value may be T2.
In addition, in the calibration stage, the user can calculate the temperature adjustment correction coefficient by the cloud, in the self-positioning adjustment stage of the user, after the cloud determines the temperature adjustment correction coefficient of the cell to which the current position of the user belongs, the temperature adjustment correction coefficient can be sent to the air conditioner, the air conditioner obtains the corrected temperature according to the measured temperature and the temperature adjustment correction coefficient, and the air conditioner performs on-off control according to the corrected temperature, or the cloud calculates the corrected temperature and sends the corrected temperature to the air conditioner, and the air conditioner performs on-off control according to the corrected temperature, or the cloud calculates the corrected temperature and sends an on-off instruction to the air conditioner according to the corrected temperature to control the on-off of the air conditioner.
The temperature after the correction is obtained according to the temperature regulation correction coefficient, and the air conditioner is controlled according to the corrected temperature, so that the comfort requirement of a user can be met, the comfort is used as an index for temperature regulation, the use experience of the user is improved, and the energy consumption of the air conditioner is reduced.
