[0047] Terms such as "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices. 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0048] This embodiment provides an application scenario. As shown in Figure 2 , the scenario includes an air conditioner installed on the wall of a room, and the room is a rectangular bedroom. The outdoor temperature is higher than 27 degrees. The user uses a remote control to turn on the air conditioner in the room. The set temperature of the air conditioner is 27 degrees. The user is sitting at position A near the air conditioner watching TV. After that, the user is going to go to position C to go to bed and fall asleep. Position C is on the right side of the air conditioner and is slightly farther away from the air conditioner. After a while, the user feels a little hot. After turning on the light and finding the remote control, the user turns the temperature down to 24 degrees. After some time, the user feels a little cold, so the user turns on the light again to find the remote control and turns the temperature up to 26 degrees. In a possible situation, the user is older and more sensitive to hot and cold. At the same time, for users of this age group, some have a lower educational level and their eyesight has also declined. It is more difficult to see the content displayed on the remote control clearly, and the operation of the remote control is not very proficient, resulting in multiple temperature adjustments and it is not easy to achieve the comfort level expected by the user.

[0049] Based on the above situation, an embodiment of the present invention provides a temperature control method for an air conditioning device, which is applied to the air conditioning device. The air conditioning device can be a split air conditioner with an indoor unit and an outdoor unit. The air conditioning device can apply the method of this embodiment to perform three-dimensional modeling on a room, output the wind speed distribution data and temperature distribution data of the room, and then combine the position and activity data of the user, so as to automatically perform temperature adjustment control in a targeted and real-time manner to achieve the comfort expected by the user and be suitable for various user groups.

[0050] Combined with Figure 1 As shown in the flowchart, an embodiment of the present invention provides a temperature control method for an air conditioning device, which is applied to the air conditioning device. The air conditioning device includes a device main body, a ranging module installed on the device main body, and a camera module installed on the device main body for user identification; wherein, the ranging module is used for distance measurement. In this embodiment, the ranging module measures the coordinates of multiple vertices of the room where the air conditioning device is located. In this embodiment, the position of the ranging module is used as the coordinate origin, and at the same time, it is also used as the position of the air outlet of the air conditioner. In addition, the position of the camera module relative to the ranging module is known. The temperature control method for an air conditioning device provided by an embodiment of the present invention includes steps 101-step 105:

[0051] Step 101: Obtain the indoor temperature, outdoor temperature, indoor fan speed, outdoor fan speed, compressor frequency, indoor humidity, and air conditioner set temperature;

[0052] In this embodiment, the indoor temperature refers to the temperature inside the room where the air conditioning device is located. The outdoor temperature refers to the ambient temperature outside the room. The outdoor temperature can be obtained through weather forecast information or manually input by the user. The fans of the air conditioning device include an indoor fan and an outdoor fan. The indoor fan mainly absorbs heat during air conditioning cooling and draws away the indoor cold air during heating. The outdoor fan assists the outdoor heat exchanger in heat exchange. The indoor humidity refers to the content of water vapor in the air inside the room. The air conditioner set temperature refers to the currently set temperature that the user expects the indoor to reach. When the air conditioning device is just turned on, the air conditioner set temperature can be the temperature set during the last use or a fixed temperature set by the user.

[0053] For example, after the user used the air conditioning device yesterday, the set air conditioner set temperature was 25 degrees. When the user turns on the air conditioning device today, if the user does not adjust the air conditioner set temperature, the default current air conditioner set temperature is 25 degrees. If the set air conditioner set temperature was 23 degrees after the user used the air conditioning device last time, but the user fixes the air conditioner set temperature at 25 degrees each time the air conditioning device is turned on according to habit, then after the user turns on the air conditioning device today, the air conditioner set temperature is 25 degrees.

[0054] Step 102: Based on the camera module, identify the user activities in the room to obtain position and activity data;

[0055] In this embodiment, a camera module is installed on the air conditioning device, and the camera module is used to identify the user activities in the room where it is located. After the air conditioning device in the room is turned on, the user's activity location may be fixed or may not be fixed. For example, as shown in Figure 2 After the user turns on the air conditioning device in the room in the afternoon, at 1 o'clock in the afternoon, the user sits at position A watching TV. At 1:30 in the afternoon, the user receives a call from his mother and stands up to go to position B by the window to make a call; at 2 o'clock in the afternoon, the user goes to position C to go to bed and start taking a nap.

[0056] It is not difficult to see that during this period in the afternoon, the user is mainly at position A, position B, and position C. And these three positions are at different positions in the room and are also different relative to the position of the air conditioning device. It is not difficult to understand that even at the same moment, at different positions in the room, the temperature and wind speed felt by the user are different, and thus the comfort feeling of the user is also different.

[0057] For example, in combination with Figure 2 the schematic diagram of the user's activities in the room described above. This room is a rectangular room, and the surrounding of the room is connected by wall 1, wall 2, wall 3, and wall 4 in sequence. The indoor unit of the air conditioning device is installed on wall 1, and the air conditioning device is close to one side of wall 2 and far from one side of wall 4. The air conditioning device is currently in the cooling mode, the set temperature of the air conditioning is 23 degrees, and the wind speed is 0.3 m / s. At 1 o'clock in the afternoon, the user sits at position A watching TV. Position A is directly opposite the air outlet of the air conditioner, and the wind blown out from the air conditioning device will directly blow on the user. At this time, the user feels a bit cold. At 1:30 in the afternoon, the user receives a call from his mother and stands up to go to position B by the window to make a call. Position B is a bit farther from the air conditioning device compared to position A, and the user feels comfortable at position B; at 2 o'clock in the afternoon, the user goes to position C to go to bed and start taking a nap. Position C is on the right side of the air conditioning device and is relatively close to the air conditioning device, but not directly opposite the air outlet. The user feels comfortable when at position C.

[0058] Since the user may move at different positions in the room, and the user's comfort feeling at different positions in the room is different. Based on this, when controlling the adjustment of the air outlet temperature in this example, the user's activities in the room will be considered. In implementation, in an optional implementation manner, the camera module can be used to identify the user activities in the room, and measure the user's position and the distance to the camera, so as to obtain the user's position activity data.

[0059] It should be noted that the location activity data can mark the user's activity locations within a preset time period and accumulate the stay time of the user at each activity location. Based on the activity locations and the accumulated stay time at the activity locations, the location activity data is obtained. Among them, the preset time period can be set according to the actual situation. For example, it can be 1 minute, 10 minutes, 1 hour, etc., and this embodiment does not limit it.

[0060] It should be noted that the stay time of the user at some locations is very short. Although it is detected that the user stays at this location, these locations are not representative of the stay locations and can be considered as the moving process. For example, when the user moves to location B, the user may stay at location B for a period of time, or may stay briefly and then move to location C. For example, when the user moves to location B to drink water, the user stays at location B for 20 seconds and then moves to location C to watch TV and stays at location C for 1 hour and 30 minutes.

[0061] Therefore, it is necessary to perform screening processing on the location activity data. In an optional implementation manner, a stay threshold can be set, and for the activity locations where the accumulated stay time is less than the stay threshold, these activity locations are filtered out.

[0062] Step 103: Establish a three-dimensional room model based on the dimension data measured by the ranging module for the room;

[0063] In this embodiment, the ranging module will measure the dimension data of the room, that is, measure the coordinates of multiple vertices of the room through the ranging module. Commonly, the room is mostly rectangular or close to a rectangular shape. For such a room, the ranging module measures the vertex coordinates of the room. Then, based on the measurable vertex coordinates, a three-dimensional room model is established. Among them, the location where the ranging module is located is used as the position of the air outlet of the air conditioning device.

[0064] In an optional implementation manner, the dimension data of the room can also be input by the user. For example, the user can upload the dimension diagram of the room to the mobile APP related to the air conditioning device by taking a photo; or, the user manually selects the shape of the room in the mobile APP related to the air conditioning device, marks the dimension data of the room, and the position of the air outlet of the air conditioning device.

[0065] Step 104: In the three-dimensional room model, obtain the wind speed distribution data and temperature distribution data of the room according to the indoor temperature, the outdoor temperature, the indoor fan speed, the outdoor fan speed, the compressor frequency, and the air conditioning set temperature;

[0066] In this embodiment, the indoor temperature, the outdoor temperature, the indoor fan speed, the outdoor fan speed, the compressor frequency, and the air conditioner set temperature can be used as input data to obtain the wind speed distribution data and temperature distribution data of the room. This embodiment can perform simulations based on the wind speed distribution data and temperature distribution data. For example, simulations can be carried out using Comsol, Matlab, EES, etc. to obtain the wind speed distribution cloud map and temperature distribution cloud map for display to the user. The position activity data can also be combined to further obtain the wind speed distribution cloud map and temperature distribution cloud map with user position markings. In the wind speed distribution cloud map and temperature distribution cloud map, the user's current location will be clearly marked. The user can clearly and intuitively understand the current location, as well as the temperature and wind speed at that location, which can assist the user in manually adjusting the temperature. It should be noted that for the convenience of user position marking, the center point of the user's head is used to represent the user in this embodiment.

[0067] The wind speed distribution cloud map and temperature distribution cloud map with user position markings can be sent to the mobile APP associated with the air conditioning device. The user can view the wind speed distribution cloud map and temperature distribution cloud map with user position markings through the mobile APP. If the user believes that the current temperature and wind speed do not meet expectations after viewing the wind speed distribution cloud map and temperature distribution cloud map with user position markings, the outlet temperature can be adjusted. There are various adjustment methods. In an optional embodiment, the air conditioning device, the remote control, or the mobile APP can respond to the user's voice command regarding temperature adjustment. For example, the user issues a voice command such as "Set the temperature to 25 degrees" or "Raise the outlet temperature to 25 degrees". According to the user's voice command, the outlet temperature will be adjusted accordingly. This adjustment method enables the user to have an intuitive understanding of the actual data of the temperature and wind speed at the target location they want to know, which can assist the user in making more accurate judgments rather than relying solely on the user's feeling. Moreover, the user can not only adjust the outlet temperature of their own room but also adjust the outlet temperature of other rooms without having to go to other rooms in person. Especially when taking care of family members at night, this adjustment method brings great convenience to the user. That is to say, the person located at the target position can be the user himself, or it can be the user's child, elderly person, or other people with relatively weak behavioral abilities who need the user's care.

[0068] For example, when the air conditioning equipment in a room is turned on and in the cooling mode, and the user's child a is sleeping in the room. To avoid the child a catching a cold due to too low temperature, the user can view the wind speed distribution cloud map and temperature distribution cloud map marked with the position of child a on the mobile phone APP, and judge whether the outlet temperature needs to be adjusted by combining the wind speed distribution cloud map and temperature distribution cloud map. If the user feels that the temperature at the position where child a is located is too low or the wind speed is too high, the user can issue a voice command to the mobile phone APP to increase the outlet temperature. The user doesn't need to go to the child's room to check in person.

[0069] Step 105: According to the wind speed distribution data, temperature distribution data of the room and the position activity data, perform comfort judgment, and control the adjustment of the outlet temperature based on the comfort judgment result.

[0070] In this embodiment, if the user doesn't want to manually adjust the outlet temperature, it can be set so that the device automatically adjusts the outlet temperature. Specifically, according to the wind speed distribution data, temperature distribution data of the room and the position activity data, perform comfort judgment, and then determine how to adjust the outlet temperature according to the comfort judgment result.

[0071] Among them, this embodiment will preset an objective comfort judgment standard. For example, when the temperature is 25 degrees and the wind speed is 0.3 m / s, it is considered moderate. However, comfort judgment varies from person to person. Therefore, the comfort judgment standard in this embodiment is adjustable. The user can make personalized adjustments based on their historical usage habits on the basis of the preset objective comfort judgment standard. Subsequently, when controlling the adjustment of the outlet temperature, the personalized comfort standard adjusted by the user will be used for judgment.

[0072] In an alternative embodiment, controlling the adjustment of the outlet temperature based on the comfort judgment result includes:

[0073] If the comfort judgment result is on the hot side, increase the compressor frequency and / or increase the indoor fan speed to lower the outlet temperature;

[0074] If the comfort judgment result is on the cold side, decrease the compressor frequency and / or decrease the indoor fan speed to increase the outlet temperature;

[0075] If the comfort judgment result is moderate, keep the current outlet temperature.

[0076] In this embodiment, the comfort judgment result is mainly divided into 3 categories, namely moderate, on the cold side, and on the hot side. Of course, the comfort judgment result can also be further subdivided, such as moderate, on the cold side, extremely cold, on the hot side, extremely hot, etc. This embodiment does not limit this.

[0077] In this embodiment, if the comfort judgment result is too hot, the outlet temperature needs to be reduced, which can be achieved by increasing the compressor frequency and / or increasing the indoor fan speed. If the comfort judgment result is too cold, the outlet temperature needs to be increased, which can be achieved by decreasing the compressor frequency and / or decreasing the indoor fan speed. If the comfort judgment result is moderate, the current outlet temperature can be maintained.

[0078] It should be noted that this embodiment will determine the user's comfort level in combination with the user's location activity data. However, within a certain period of time, the user's activity location may not be fixed. Based on this, in an alternative embodiment, all the activity locations of the user within a preset duration can be determined according to the user's location activity data, and the weight of each activity location can be calculated using a weighted algorithm based on the cumulative stay time at each activity location. Then, in combination with the temperature at each location, the comprehensive temperature and comprehensive wind speed around the user can be finally calculated, and the comfort judgment can be made based on the comprehensive temperature and comprehensive wind speed.

[0079] For example, in combination with Figure 2 As shown, if the preset objective comfort judgment standard is that the temperature is between 24 - 26 degrees and the wind speed is between 0.2 - 0.4 m / s for moderate; the temperature is less than 24 degrees for too cold; the temperature is greater than 26 degrees and the wind speed is less than 0.2 m / s for too hot. Within the preset duration of 2 hours, the effective activity locations of the user are Location A, Location B, and Location C. The user's stay time at Location A is 30 minutes, the user's stay time at Location B is 10 minutes, and the user's stay time at Location C is 1 hour. Then, when making the comfort judgment, the weight corresponding to Location A for the user is 30%, the weight corresponding to Location B for the user is 10%, and the weight corresponding to Location C for the user is 60%. According to the temperature distribution data and wind speed distribution data, the temperature at Location A is 22 degrees and the wind speed is 0.5 m / s, the temperature at Location B is 24 degrees and the wind speed is 0.4 m / s, and the temperature at Location C is 25 degrees and the wind speed is

[0080] 0.3 m / s. Combining the weight values, the comprehensive temperature around the user is calculated to be 24 degrees and the comprehensive wind speed is 0.37 m / s, and the comfort judgment is made based on the comprehensive temperature and comprehensive wind speed to determine that the comfort judgment result is moderate.

[0081] In another alternative embodiment, all the activity locations of the user within a preset duration can be determined according to the user's location activity data, and the activity location with the longest stay time can be determined based on the cumulative stay time at each activity location, and then the comfort judgment can be made based on the temperature and wind speed at that activity location.

[0082] For example, in combination with Figure 2As shown, if the preset objective comfort judgment criteria are that the temperature is between 24 - 26 degrees and the wind speed is between 0.2 - 0.4 m / s is moderate; the temperature is less than 24 degrees is on the cold side; the temperature is greater than 26 degrees and the wind speed is less than 0.2 m / s is on the hot side. The effective activity positions of the user within the preset duration of 2 hours are position A, position B, and position C. The user stays at position A for 30 minutes, stays at position B for 10 minutes, and stays at position C for 1 hour. Then, when making a comfort judgment, the user stays at position C for the longest time. The temperature at position C is 25 degrees and the wind speed is 0.3 m / s. Then, based on this, a comfort judgment is made, and the comfort judgment result is determined to be moderate.

[0083] In this embodiment, the steps for obtaining the wind speed distribution data and temperature distribution data of the room may include:

[0084] Based on the indoor temperature, the outdoor temperature, the indoor fan speed, the outdoor fan speed, the compressor frequency, and the air conditioner set temperature, determine the outlet temperature and outlet air volume of the air conditioner;

[0085] In the three - dimensional model of the room, based on the outlet temperature, the outlet air volume, the indoor temperature, and the heat transfer coefficient of the preset heat - exchange wall, obtain the wind speed distribution data and temperature distribution data of the room.

[0086] Among them, the outlet temperature refers to the temperature of the cold or hot air blown out from the outlet of the air - conditioning equipment when the compressor starts. Many users think that the outlet temperature is the air - conditioner set temperature set by the remote control or mobile phone APP, but actually the outlet temperature and the air - conditioner set temperature are not the same thing.

[0087] For example, when the air - conditioning equipment is in the cooling mode, if the indoor and outdoor temperatures are both 35 degrees and the air - conditioner set temperature is 25 degrees, after the compressor starts and reaches a stable state after a period of time, the outlet temperature will be much lower than 25 degrees because the air - conditioning equipment needs to reduce the indoor temperature of 35 degrees to 25 degrees by blowing cold air, so the outlet temperature must be lower than 25 degrees. Similarly, when the air - conditioning equipment is in the heating mode, the outlet temperature will also be much higher than the air - conditioner set temperature and can even rise above 40 °C. The outlet temperature and outlet air volume are mainly affected by the indoor temperature, outdoor temperature, indoor fan speed, outdoor fan speed, compressor frequency, and air - conditioner set temperature. When the indoor temperature, outdoor temperature, indoor fan speed, outdoor fan speed, compressor frequency, and air - conditioner set temperature are determined, the outlet temperature and outlet air volume can be calculated.

[0088] It should be noted that, for the convenience of position determination and display, the three-dimensional room model is also divided into regions in this embodiment to obtain the divided three-dimensional room model. For example, the three-dimensional room model is divided into a checkerboard pattern according to the target distance to obtain the divided three-dimensional room model.

[0089] It is easy to understand that the walls in a room mainly include side walls, a ceiling, and a floor. The walls of the room will exchange heat with the outside world, affecting the temperature distribution in the room. If the house is a multi-story building, the side walls are mainly responsible for the obvious heat exchange. If the house is a single-story house, the ceiling and side walls are responsible for the obvious heat exchange. Considering that most houses are multi-story buildings nowadays, the side walls are used as the heat exchange walls in this embodiment, and the heat transfer coefficient of the heat exchange walls is preset. Of course, the side walls, ceiling, and floor can also be used as heat exchange walls, and this embodiment does not limit this. Then, combining the three-dimensional room model, the outlet temperature, and the outlet air volume, the wind speed distribution data and temperature distribution data of the room are obtained through simulation.

Through data such as indoor and outdoor temperatures, indoor and outdoor fan speeds, and the established three-dimensional room model, the wind speed distribution data and temperature distribution data of the room are determined, so that the temperature and wind speed conditions at each position in the room can be understood. Then, combined with the user's position activity data, the temperature and wind speed at the user's location can be judged, so as to accurately judge whether the user feels comfortable, and then adjust and control the outlet temperature in a targeted manner. It can help users achieve automatic and precise control of comfort, eliminating the process of users manually adjusting the air conditioner. At the same time, it can be adjusted in real time according to the different positions of the user, avoiding being too cold or too hot caused by the user changing the activity position. It greatly improves the comfort and convenience of users.
