[0001] The present application relates to the technical field of intelligent control, in particular to an air conditioner and a projection device interconnection control method and device and an air conditioner. BACKGROUND

[0002] With the development of society and the continuous improvement of people's living standards, people's requirements for the quality of life are also getting higher and higher. People pay more and more attention to the comfort of the living environment, and the demand for environmental regulation equipment in daily life or work is not limited to traditional functions. More and more people hope that they can make various adjustments according to the real-time needs of users. The environmental regulation equipment can be an air conditioner and other household appliances for regulating environmental air parameters. However, most of the current environmental regulation equipment cannot well interpret the concept of interconnection with other devices due to the limitations of their own functions and structures. For example, the current air conditioner and projection device cannot be effectively interconnected, cannot be intelligently adjusted according to the actual state of each other, and the user experience is poor. SUMMARY

[0003] The inventor realizes that projection devices are not only widely used in office areas, but also increasingly used in homes to watch movies, online courses, etc. However, the projection light emitted by the projection device is strong, and if the eyes of young children, the elderly, or even adults in the family directly contact the projection light, it will bring strong irritation and discomfort, and even affect the eye development of some users and damage their vision, which has serious safety hazards.

[0017] Optionally, the air conditioner is provided with a light detection device; and

[0018] The step of detecting whether a darkening situation exists on the projection screen comprises:

[0019] acquiring light intensity information on the projection screen in real time or periodically through the light detection device;

[0020] comparing the light intensity information acquired this time with light intensity information acquired last time;

[0021] if the light intensity contained in the light intensity information acquired this time is less than the light intensity contained in the light intensity information acquired last time, determining that a darkening situation exists on the projection screen.

[0022] Optionally, the step of judging whether a darkened area on the projection screen is a whole area or a local area of the projection screen comprises:

[0023] calculating an area of the darkened area and a whole area of the projection screen;

[0024] determining a preset limit area according to the whole area of the projection screen; and

[0025] if the calculated area of the darkened area is less than the preset limit area, determining that the darkened area on the projection screen is a local area of the projection screen; otherwise, determining that the darkened area on the projection screen is a whole area of the projection screen.

[0026] Optionally, in the protection mode, the interconnection control method further comprises:

[0027] acquiring a user type in the projection range; and

[0036] Optionally, after the protection mode is started, the interconnection control method further comprises:

[0037] detecting whether there is a local shadow on the projection screen;

[0038] if yes, keeping the protection mode unchanged;

[0040] According to a second aspect of the present application, the present application further provides an interconnection control device of an air conditioner and a projection device, the projection device and the air conditioner being in the same indoor environment space; and

[0041] the interconnection control device comprising a processor and a memory, the memory storing a machine executable program, and the machine executable program being executed by the processor to implement the interconnection control method according to any one of the above-mentioned schemes.

[0042] According to the second aspect of the present application, the present application further provides an air conditioner comprising the interconnection control device according to any one of the above-mentioned schemes.

[0043] The application provides an interconnection control method of an air conditioner and a projection device. The air conditioner and the projection device are in the same indoor environment space, so that the air conditioner and the projection device work cooperatively to realize more intelligent regulation and control. Specifically, the interconnection control method detects whether a local darkening of a projection screen of the projection device occurs in a normal projection process of the projection device. If the local darkening occurs, it indicates that a human body exists in a projection range of the projection device. At this time, the projection device is automatically controlled to switch from a normal projection mode to a protection mode, so that the user in the projection range is protected by starting the protection mode, and discomfort of the user caused by strong stimulation of the projection light on the eyes of the user or safety hazards such as eye development disorder and vision damage are effectively avoided. The application uses interconnection of the air conditioner and the projection device to achieve the above purpose, has high intelligence, provides a scene of intelligent interconnection of household appliances, and effectively improves the intelligence.

[0044] The inventor realizes that, in the normal projection process of the projection device, if the projection screen darkens, there may be two cases. One is that the darkening is caused by a change in display content on the projection screen, and the other is that a user enters the projection range of the projection device and blocks part of the projection light emitted by the projection device. The inventor further realizes that the two cases are obviously different. The first case is caused by the display content, so the brightness change is integral. The second case is caused by the user, and the volume of the user is much smaller than that of the projection screen. Therefore, the user can only block part of the projection light, so the brightness change caused thereby is local, rather than integral. Therefore, the application further judges whether the darkening region is an integral region of the projection screen or a local region of the projection screen when detecting that the projection screen darkens, so as to distinguish the real cause of the darkening of the projection screen, which is very close to the actual situation, and the accuracy of the judgment result is very high. Moreover, the scheme of the application only needs to set a detection device capable of detecting the brightness of the projection screen, so the structure is simple and the cost is low.

[0054] The present application first provides an interconnection control method of an air conditioner and a projection device, which can realize intelligent interconnection of the air conditioner and the projection device, provides a smart home appliance interconnection scene, and effectively improves the intelligent degree.

[0055] Specifically, the projection device and the air conditioner are in the same indoor environment space, so as to facilitate cooperative work of the air conditioner and the projection device, thereby realizing more intelligent regulation and control.

[0056] It should be noted that the methods of the following embodiments of the present application are described from the side of an interconnection control device of the air conditioner and the projection device, that is, the control device executes the related steps. And, the precondition for realizing the following embodiment schemes of the present application is that the air conditioner and the projection device are interconnected. Specifically, the interconnection control device of the air conditioner and the projection device can be arranged between the air conditioner and the projection device. The control device can receive signals sent by the air conditioner and the projection device, and can send signals to the air conditioner and the projection device. The control device can be additionally and independently arranged, or arranged in the air conditioner.

[0057] The projection device in the embodiment has the intelligent feature. It is just because of the above-mentioned that it can send signals to the control device and receive signals sent by the control device. Specifically, a controller can be arranged on the projection device to realize this. Similarly, the air conditioner can also be provided with its own controller, so as to send signals to the control device and receive signals sent by the control device.

[0058] Figure 1is a schematic flow chart of an interconnection control method of an air conditioner and a projection device according to an embodiment of the present application. Referring to Figure 1 The interconnection control method of the present application comprises:

[0059] Step S10, judging whether the projection device is in a projection running state; if yes, turning to step S20; if no, returning to continue judging;

[0060] Step S20, detecting whether there is a local darkening situation on the projection screen corresponding to the projection device; if yes, turning to step S30; if no, returning to continue detecting;

[0061] Step S30, determining that there is a human body in the projection range covered by the projection light emitted by the projection device; and

[0062] Step S40, controlling the projection device to switch from a normal projection mode to a protection mode with an eye protection function.

[0063] It should be noted that the projection device being in the projection running state means that the projection device receives a start signal to start the process of normal projection, and the working mode is the normal projection mode without any interference factors.

[0064] Figure 2 is a working scenario schematic diagram of a projection device according to an embodiment of the present application. Referring to Figure 2 The projection direction of the projection device 100 corresponds to the projection screen 200, and the projection light emitted by the projection device 100 is projected onto the projection screen 200, thereby displaying relevant information on the projection screen 200.

[0065] Further, the aforementioned projection range 300 of the projection device 100 means all the space regions covered by the projection light emitted by the projection device 100, that is, the region shown by the section line in Figure 2 It can be understood that the region is a three-dimensional space, rather than a planar space.

[0066] The inventor realizes that when the human body is in the projection range 300, it will block part of the projection light emitted by the projection device 100, and a local darkening situation occurs, referring to the darkening region 400 in Figure 2 Therefore, when the local darkening situation occurs on the projection screen 200, it can be determined that there is a human body in the projection range 300.

[0067] The interconnection control method of the present application detects whether the projection screen of the projection device appears local darkening during the normal projection process of the projection device, if yes, it means that there is a human body in the projection range of the projection device, at this time, the projection device is automatically controlled to switch from the normal projection mode to the protection mode, so as to protect the user in the projection range by starting the protection mode, effectively avoiding the user's eyes from being strongly stimulated by the projection light and causing discomfort or bringing security risks such as eye development disorder and vision damage.

[0068] The present application realizes the above-mentioned purpose by interconnection of the air conditioner and the projection device, and has high intelligence.

[0069] Specifically, the normal projection mode of the projection device is the projection mode when the projection device normally works. The protection mode of the projection device has an eye protection function. In the protection mode, the projection device has many ways to realize the eye protection function, which will be described in subsequent embodiments.

[0070] In some embodiments, the step of detecting whether the projection screen corresponding to the projection device exists local darkening can specifically include:

[0071] detecting whether the projection screen appears darkening;

[0072] if yes, judging whether the darkening area on the projection screen is the overall area or the local area of the projection screen; and

[0073] if it is the local area, determining that the projection screen exists local darkening.

[0074] The inventor realizes that during the projection process of the normal operation of the projection device, if the projection screen darkens, there can be two situations, one is the brightness darkening caused by the change of the display content on the projection screen, and the other is that a user enters the projection range of the projection device and blocks part of the projection light emitted by the projection device. The inventor further realizes that the obvious difference between the two situations is that the first situation is caused by the display content, so its brightness change is overall, and the second situation is caused by human, the volume of the user is much smaller than the projection screen, so the user can only block part of the projection light, and the brightness change caused thereby is local, not overall.

[0075] Therefore, the present application further judges whether the darkening area is the overall area or the local area of the projection screen when detecting that the projection screen appears darkening, so as to distinguish the real reason causing the darkening of the projection screen, which is very close to the actual situation, so the accuracy of the judgment result is very high.

[0076] Moreover, the present application only needs to set a detection device capable of detecting the brightness of the projection screen, which has simple structure and low cost.

[0077] Specifically, Figure 3 is a schematic flow chart of the interconnection control method of the air conditioner and the projection device according to the second embodiment of the present application. Referring to Figure 3 , the interconnection control method of the present application comprises:

[0078] Step S10, judging whether the projection device is in a projection running state; if yes, proceeding to step S20; if no, returning to continue judging;

[0079] Step S21, detecting whether the projection screen appears to be darkened; if yes, proceeding to step S22; if no, returning to continue detecting;

[0080] Step S22, judging whether the darkened area on the projection screen is a whole area or a partial area of the projection screen; if a partial area, proceeding to step S30; if a whole area, returning to step S21;

[0081] Step S30, determining that there is a human body in the projection range covered by the projection light emitted by the projection device; and

[0082] Step S40, controlling the projection device to switch from a normal projection mode to a protective mode with an eye protection function.

[0083] In some embodiments, the air conditioner is provided with a light detection device. In these embodiments, the step S21 of detecting whether the projection screen appears to be darkened can specifically comprise:

[0084] acquiring light intensity information on the projection screen in real time or periodically through the light detection device;

[0085] comparing the light intensity information acquired this time with the light intensity information acquired last time;

[0086] if the light intensity contained in the light intensity information acquired this time is less than the light intensity contained in the light intensity information acquired last time, it is determined that the projection screen appears to be darkened.

[0087] Further, the step S22 of judging whether the darkened area on the projection screen is a whole area or a partial area of the projection screen can specifically comprise:

[0088] calculating the area of the area with the minimum light intensity on the projection screen and the whole area of the projection screen;

[0089] determining a preset limit area according to the whole area of the projection screen; and

[0090] if the calculated area is less than the preset limit area, it is determined that the darkened area on the projection screen is a partial area of the projection screen; otherwise, it is determined that the darkened area on the projection screen is a whole area of the projection screen.

[0091] It can be understood that when the parameters (e.g. focal length) of the projection device are different, the size of the corresponding projection screen is also different. Therefore, the overall area of the projection screen must be actually obtained when the comparison and analysis is performed.

[0092] Further, the preset limit area can be the overall area of the obtained projection screen, or can be slightly smaller than the overall area of the obtained projection screen, so that the judgment result is more accurate.

[0093] In some embodiments, in the protection mode, the interconnection control method of the application further comprises:

[0094] obtaining the user type in the projection range; and

[0095] selectively turning off the projection device or reducing the brightness of the projection device according to the user type.

[0096] That is, according to the different user types in the projection range, the specific execution mode in the protection mode is also different, so that the protection mode of the projection device is more matched with the safety level required by the user in the projection range, thereby realizing the special protection of the user in the special projection range without affecting the viewing process of the user as much as possible.

[0097] Further, the step of selectively turning off the projection device or reducing the brightness of the projection device according to the user type comprises:

[0098] judging whether the user in the projection range is a child or a baby whose height is lower than a preset height value;

[0099] if yes, turning off the projection device; and

[0100] if no, reducing the brightness of the projection device.

[0101] The inventor realizes that for the low-age children and babies whose height is lower than the preset height value, the visual development is not yet sound, and the consequences caused by strong light stimulation are more serious. Moreover, such users do not have any cognition of the projection device, and even have great interest and attraction to the light-emitting projection device, and are easy to approach the projection device, so that the eye damage to such users is more serious in this case.

[0102] Therefore, when it is judged that the user in the projection range is a child or a baby whose height is lower than the preset height value, the projection device is directly turned off so that the light-emitting brightness is zero, thereby directly cutting off the source of eye damage to such users and completely avoiding the harm to the eye health of such users. When the user in the projection range is other than the low-age children and babies whose height is lower than the preset height value, the brightness of the projection device can be reduced, thereby reducing or even avoiding the damage to such users without affecting the normal viewing.

[0103] In some embodiments, in the protection mode, the interconnection control method further comprises:

[0104] sending, by the air conditioner and / or the projection device, first prompt information for indicating the user to move out of the projection range.

[0105] In the protection mode, the interconnection control method of the present application further sends the first prompt information by the air conditioner and / or the projection device, so as to timely remind the user in the projection range to move out of the projection range as soon as possible, so as to reduce the stimulation time and damage degree of the projection light on the user's eyes as much as possible, and effectively achieve the prompting purpose.

[0106] It can be understood that this embodiment is more suitable for users with cognitive and discrimination abilities and autonomous activity abilities, such as users other than children or infants whose heights are lower than the preset height value.

[0107] The inventor realizes that the user in the projection range can be a young child or an infant who has no cognition of the projection device, at this time, even if the above-mentioned prompt information is sent by the air conditioner and / or the projection device, such user will not accurately understand the meaning of the prompt information.

[0108] Therefore, in some embodiments, in the protection mode, the interconnection control method of the present application further comprises:

[0109] sending, to a mobile terminal interconnected with the air conditioner and / or the projection device, second prompt information for indicating that there is a user in the projection range.

[0110] In the protection mode, the interconnection control method of the present application further sends the prompt information to the terminal device interconnected with the air conditioner and / or the projection device, so as to timely remind the guardian that there is a user in the projection range, so as to facilitate the guardian to timely and quickly move the user without cognitive and discrimination abilities out of the projection range, and then reduce the stimulation time and damage degree of the projection light on the user's eyes as much as possible, and achieve the purpose of effective supervision.

[0111] It can be understood that this embodiment is more suitable for the case that the user is a child or an infant whose height is lower than the preset height value.

[0112] Specifically, Figure 4 is a schematic control flowchart of the projection device in the protection mode according to an embodiment of the present application. Referring to Figure 4 , in the protection mode, the interconnection control method of the present application comprises:

[0113] Step S401, acquiring a type of a user in a projection range; and

[0114] Step S402, judging whether the user in the projection range is a child with a height lower than a preset height value; if yes, turning to step S403; if no, turning to step S404;

[0115] Step S403, turning off the projection device, and sending second prompt information indicating that there is a user in the projection range to a mobile terminal interconnected with the air conditioner and / or the projection device; and

[0116] Step S404, reducing the brightness of the projection device, and sending first prompt information indicating that the user moves out of the projection range through the air conditioner and / or the projection device.

[0117] Of course, in other embodiments, the step S404 can also include sending second prompt information indicating that there is a user in the projection range to a mobile terminal interconnected with the air conditioner and / or the projection device, to further ensure that any user can move out of the projection range.

[0118] In some embodiments, after sending the second prompt information indicating that there is a user in the projection range to a mobile terminal interconnected with the air conditioner and / or the projection device, the control method of the present application further includes:

[0119] judging whether a normal projection resuming instruction sent by the terminal device is received; the normal projection resuming instruction is used to indicate that the projection device is resumed to the normal projection mode from the protection mode;

[0120] if yes, resuming the projection device to the normal projection mode according to the normal projection resuming instruction.

[0121] That is, if the guardian and other users receive the second prompt information through the terminal device, the user in the projection range can be moved out in time, at this time, the guardian and other users can send a normal projection resuming instruction through the terminal device, so that the projection device resumes the normal projection, thereby ensuring the normal operation of the projection. That is, the projection device can receive the instruction sent by the terminal device and operate according to the instruction sent by the terminal device, and the intelligent degree is high, so as to meet the use purpose of the user to the greatest extent.

[0122] In some embodiments, after the protection mode is started, the interconnected control method of the present application further includes:

[0123] detecting whether there is a local shadow on the projection screen;

[0124] if yes, keeping the protection mode unchanged;

[0125] if no, controlling the projection device to resume to the normal projection mode from the protection mode.

[0126] After the protection mode is started, the user can have moved out of the projection range through the prompting of the first prompt information and / or the second prompt information, or the user has moved out of the projection range autonomously through free activity. At this time, re-executing the protection mode will affect the viewing experience of the user. Therefore, the application still needs to continue to detect whether there is a local shadow on the projection screen after the protection mode is started, and restore the projection device to the normal projection mode after the projection screen does not have a local shadow, thereby realizing flexible switching of the working mode of the projection device on the basis of necessary protection of the user, and having a high degree of intelligence.

[0127] Specifically, Figure 5 is a schematic flow chart of an interconnection control method of an air conditioner and a projection device according to the third embodiment of the application. Referring to Figure 5 , the interconnection control method of the application comprises:

[0128] Step S10, determining whether the projection device is in a projection running state; if yes, proceeding to step S20; if no, returning to continue to determine;

[0129] Step S20, detecting whether there is a local darkening condition on the projection screen corresponding to the projection device; if yes, proceeding to step S30; if no, returning to continue to detect;

[0130] Step S30, determining that there is a human body in the projection range covered by the projection light emitted by the projection device;

[0131] Step S40, controlling the projection device to switch from the normal projection mode to the protection mode with the eye protection function;

[0132] Step S50, detecting whether there is a local shadow on the projection screen; if yes, proceeding to step S60; if no, proceeding to step S70;

[0133] Step S60, keeping the protection mode unchanged, and returning to step S50 to continue to detect;

[0134] Step S70, controlling the projection device to restore to the normal projection mode from the protection mode.

[0135] Specifically, in step S50, the specific steps of detecting whether there is a local shadow on the projection screen can be the same as or similar to those in step S20, which will not be described here.

[0136] The application further provides an interconnection control device of an air conditioner and a projection device, wherein the projection device and the air conditioner are in the same indoor environment space.

The interconnection control device 20 of the present application comprises a processor 21 and a memory 22, the memory 22 stores a machine executable program 23, and the machine executable program 23 is executed by the processor 21 to implement the interconnection control method described in any of the above embodiments.

[0138] Specifically, the processor 21 can be a central processing unit (CPU) or a digital processing unit, etc. The processor 21 transmits and receives data through a communication interface.

The memory 22 is any medium capable of carrying or storing desired program code in the form of instructions or data structures and capable of being accessed by a computer, and can also be a combination of multiple memories. The above-mentioned machine executable program 23 can be downloaded from a computer readable storage medium to a corresponding computing / processing device or downloaded to a computer or an external storage device via a network (such as the Internet, a local area network, a wide area network and / or a wireless network).

[0139] As mentioned above, the interconnection control method of the air conditioner and the projection device of any of the above embodiments is described from the side of the interconnection control device 20, that is, the relevant steps are executed by the interconnection control device 20. In a specific embodiment, the interconnection control device 20 is data-connected with the air conditioner and the projection device, which can be arranged as a server, a cloud, etc. network side device, obtains various data of the set space through the network, and realizes the relevant adjustment by remotely sending instructions to the air conditioner and the projection device.

[0140] The interconnection control device 20 can also be various types of centralized control devices, arranged in the set space, and control the air conditioner and the projection device.
