[0053] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] This application provides an intelligent control method, apparatus, projection device, and storage medium.

[0055] In some embodiments, the intelligent control device can be integrated into the projection device, and the intelligent control method of this application can be implemented by the projection device; the lighting device can be built into the projection device, which can be used as a projection device with projection function or as a lighting device.

[0056] In some embodiments, the intelligent control device can be integrated into the projection device and the lighting device, and the projection device and the lighting device can jointly implement the intelligent control method of this application; the lighting device is a lighting device associated with the projection device, which can be a lighting device connected to the projection device via the Internet, or a lighting device connected to the projection device via a data cable, signal cable, or other means.

[0057] For example, the lighting equipment is built into the projection equipment. The projection equipment can determine its own working state; when the projection equipment is in the first working state, it obtains the target brightness, target color temperature and ambient light brightness corresponding to the environment where the projection equipment is located at the current time; it determines the target current corresponding to the target brightness; it updates the target current based on the ambient light brightness to obtain the updated current; based on the updated current and the target color temperature, it controls the driving current of the lighting equipment associated with the projection equipment; when the projection equipment is in the second working state, it controls the driving current of the lighting equipment to be the current corresponding to the preset brightness and color temperature.

[0058] In this embodiment, the projection device can control its built-in lighting equipment based on its own operating status and the target brightness, target color temperature, and ambient light intensity of the environment in which the projection device is located at the current time. Therefore, this embodiment can control the brightness and color temperature of the lighting equipment according to different environments, times, and the different operating states of the projection device, meeting the needs of different users without requiring constant adjustments, thereby improving the user experience.

[0059] The following sections provide detailed descriptions of each example. It should be noted that the sequence numbers of the following embodiments are not intended to limit the preferred order of the embodiments.

[0060] In this embodiment, an intelligent control method is provided, such as... Figure 1a As shown, the specific process of this intelligent control method can be as follows:

[0061] 110. Determine the working status of the projection equipment.

[0062] The working status can include standby status, movie viewing status, screen casting status, music playback status, screen saver status, etc.; movie viewing status can be used to indicate that the projection device is playing movies, TV series, local videos, etc., and screen saver status can be used to indicate that the projection device is playing application software or local screen saver images, etc.

[0063] 120. When the projection device is in the first working state, obtain the target brightness, target color temperature and ambient light brightness corresponding to the environment where the projection device is located at the current time.

[0064] The current time refers to the current system time obtained by the projection device, which can be Beijing time.

[0065] The first working state can be standby state, screen saver state, etc.

[0066] Ambient light brightness can be the brightness of the environment in which the projection device is located at the current time, and can be measured using devices such as ambient light sensors.

[0067] Target brightness can refer to the expected brightness of the lighting equipment at the current time, without considering ambient light. Target brightness can be any value among the brightness values ​​supported by the lighting equipment.

[0068] The target color temperature can refer to the expected color temperature of the lighting equipment at the current time. The target color temperature can be any value among the color temperatures supported by the lighting equipment.

[0069] In some embodiments, the target brightness is determined based on a target brightness mapping relationship; for example, the brightness value corresponding to the current time is selected from the target brightness mapping relationship as the target brightness.

[0070] The target brightness mapping relationship is obtained by updating a preset brightness mapping relationship based on the sunrise and sunset times of the environment where the projection device is located; the preset brightness mapping relationship is used to represent the change in brightness of the lighting equipment over time. Optionally, the projection device may be equipped with a GPS module and / or a WiFi module. Based on the information collected by the GPS module and / or WiFi module, the sunrise and sunset times of the environment where the projection device is located are obtained at the current time; then, the preset brightness mapping relationship is stretched based on the sunrise and sunset times to obtain the target brightness curve.

[0071] For example, such as Figure 1b The diagram shows a preset brightness mapping relationship. Brightness can be represented as a ratio to the maximum brightness of the lighting equipment. For example, if the maximum brightness of the lighting equipment is 3000 lm, then 0-100% corresponds to 0-3000 lm respectively. Assume sunrise time is sr and sunset time is ss. Figure 1c The brightness of sunrise (6 AM) in the curve is shifted to the sr position, and the brightness of sunset (6 PM) in the curve is shifted to the ss position; at the same time, the curve is scaled by (ss-sr / 18-6) times to obtain a brightness curve that matches the time of day in the environment where the projection device is located.

[0072] In some embodiments, the target color temperature is determined based on a target color temperature mapping relationship, wherein a preset color temperature mapping relationship is used to represent the change in color temperature of the lighting equipment over time. The target color temperature mapping relationship is obtained by updating the preset color temperature mapping relationship based on the sunrise and sunset times of the environment where the projection device is located. Similarly, the preset color temperature mapping relationship can be stretched based on the sunrise and sunset times of the environment where the projection device is located at the current time to obtain the target color temperature mapping relationship.

[0073] Optionally, the preset color temperature mapping relationship and preset brightness mapping relationship can be updated each time the projection device is turned on or daily to obtain the target color temperature mapping relationship and target brightness mapping relationship. This allows the brightness and color temperature of the light to match the changes of sunrise and sunset each day.

[0074] It should be noted that the preset brightness mapping relationship and preset color temperature mapping relationship can be obtained by fitting the color temperature and brightness of sunlight, which can be collected using instruments such as lux meters. Optionally, the fitted mapping relationship can be multiplied by a preset coefficient to obtain the preset brightness mapping relationship and preset color temperature mapping relationship; this preset coefficient can be customized according to the actual application, and can be 1.1, 1.2, etc. Optionally, considering that users need to take a nap during the midday period, the color temperature and brightness can be reduced during the midday period (12-2 pm). Figure 1c As shown, curve 1 represents the original color temperature mapping relationship, and curve 2 represents the preset color temperature curve after reducing the color temperature during the midday period.

[0075] It's important to note that in the preset brightness mapping and preset color temperature mapping, the color temperature and brightness before sunrise and after sunset can be customized according to the actual application. For example, they can be set to fixed values, such as a color temperature of 2000K and a brightness of 1350lm; they can also be set to fixed proportional coefficients, such as a color temperature of 45% of the maximum color temperature of the lighting equipment and a brightness of 45% of the maximum brightness; or they can be set to gradually changing variables and fixed values, such as... Figure 1c The curve shown is after 18 o'clock.

[0076] In some embodiments, the following steps may be performed each time the projector is turned on, or at preset intervals (such as once a week or once a month):

[0077] a) Obtain historical usage data of the projection equipment.

[0078] Historical usage data may include: the time when the user turns the lighting equipment on and off, the time when the brightness or color temperature of the lighting equipment is adjusted and the adjusted brightness or color temperature, the working status of the projection equipment when adjusting the color temperature and brightness, etc.

[0079] b) Based on historical usage data, determine the target time period in which the user is in the target state.

[0080] The target state can be a lunch break, or a state of being away from the environment where the projection device is located. For example, if a user turns off the lights at 12:30 every day and turns them on at 2:00, it may indicate that the user is in a lunch break state from 12:30 to 2:00, so the target time period is from 12:30 to 2:00.

[0081] Optionally, the projection device can also determine the target time period in which the user is in a target state based on wireless sensing technology or image processing of the collected image information.

[0082] c) Determine the brightness and color temperature corresponding to the target state.

[0083] It can provide a user interface to allow users to customize the brightness and color temperature corresponding to the target state; it can also preset the brightness and color temperature corresponding to the target state in the projection device; it can also determine the brightness and color temperature corresponding to the target state based on the brightness and color temperature adjusted by the user during the target time period, based on the brightness and color temperature.

[0084] d) Update the brightness corresponding to the target time period in the preset brightness mapping relationship to the brightness corresponding to the target state, and update the color temperature corresponding to the target time period in the preset color temperature mapping relationship to the color temperature corresponding to the target state.

[0085] 130. Determine the target current corresponding to the target brightness.

[0086] The target current can refer to the current that drives the lighting equipment to achieve the target brightness. It can be expressed as a ratio to the rated current of the lighting equipment. For example, if the rated current of the lighting equipment is 1600mA, then 0-100% corresponds to 0-1600mA, or 0-1000‰ corresponds to 0-1600mA.

[0087] In some embodiments, determining the target current corresponding to the target brightness may include: obtaining the slope coefficient, the preset coefficient, and the accuracy of the brightness of the lighting device; and determining the target current corresponding to the target brightness based on the mapping relationship between the slope coefficient, the preset coefficient, the accuracy of the brightness of the lighting device, the target brightness, and the first preset index.

[0088] In this context, the base 'a' in the first preset index mapping relationship can be determined based on the brightness precision of the lighting equipment; this precision refers to how many brightness levels the lighting equipment can support. For example, if the lighting equipment supports 1000 brightness levels, 0-1000‰ corresponds to 0-1600mA respectively, meaning the brightness precision of the lighting equipment is 1000; then the base can be 10. If the lighting equipment supports 625 brightness levels, then the base can be 5.

[0089] The slope coefficient is used to represent the smoothness of the first preset exponential mapping relationship. The slope coefficient can be customized according to the actual application. Optionally, the preset coefficient is obtained based on the slope coefficient, assuming that the brightness accuracy of the lighting equipment adopts a... n This means that the sum of the preset coefficient and the slope coefficient equals n; for example, if the precision is 1000, n is 3, and the slope coefficient is 2.5, then the preset coefficient is 0.5. A larger slope coefficient means that when the brightness of the lighting equipment is low, the change in current is slower when the brightness is increased; conversely, when the brightness of the lighting equipment increases, the rate of change in current also increases. This way, users will not feel the stimulation of increased brightness at low brightness levels; that is, the increase in brightness is more linear for the human eye, thus improving the user experience.

[0090] For example, taking the base of the first preset exponent mapping relationship as 10, the first preset exponent mapping relationship can be expressed as follows:

[0091] C=10^((B-δ) / ((K1-δ) / K2)+K3)

[0092] Where C represents the current of the lighting equipment; B represents the brightness of the lighting equipment; K1 represents the accuracy of the brightness of the lighting equipment; K2 represents the preset coefficient; and K3 represents the slope coefficient. δ represents a difference used for fine-tuning when calculating the target current to prevent the target current from exceeding the rated current; its value can be customized according to the actual application, for example, it can be 1. Substituting the obtained slope coefficient, preset coefficient, brightness accuracy of the lighting equipment, and target brightness into the first preset exponential mapping relationship yields the target current.

[0093] In some embodiments, determining the target current corresponding to the target brightness may include: acquiring a slope coefficient, a preset coefficient, and the accuracy of the brightness of the lighting device; determining the target current corresponding to the target brightness based on the slope coefficient, the preset coefficient, the accuracy of the brightness of the lighting device, the target brightness, and a second preset exponential mapping relationship; wherein, the second preset exponential mapping relationship adds a target linear coefficient compared to the first preset exponential mapping relationship, and the target linear coefficient is determined by a preset proportional coefficient, the accuracy, and the brightness of the lighting device. The preset proportional coefficient is determined based on the accuracy of the lighting device and the rated current of the lighting device; for example, if the rated current is 1600mA and the accuracy is 1000, then the preset proportional coefficient is 1.6; if the rated current is 1600mA and the accuracy is 100, then the preset proportional coefficient is 16.

[0094] For example, taking the base of the second preset exponent mapping relationship as 10, the second preset exponent mapping relationship can be expressed as follows:

[0095] C=(10^((B-δ) / ((K1-δ) / K2)+K3))*K*B / K1

[0096] Where K represents a preset scaling factor. By substituting the obtained slope coefficient, preset coefficient, accuracy, preset scaling factor, and target brightness into the second preset exponential mapping relationship, the target current can be obtained. For example... Figure 1d The diagram shown illustrates a second preset index mapping relationship provided in this embodiment. The horizontal axis represents brightness expressed as a ratio (0-1000‰), and the vertical axis represents the current of the lighting equipment, with a rated current of 1600mA. Figure 1d As shown, the target linear coefficient is used to fine-tune the slope of the latter part of the curve, so that when the brightness of the lighting equipment is high, the user can adjust the brightness and feel a more uniform and comfortable change in brightness.

[0097] In some embodiments, determining the target current corresponding to the target brightness includes: obtaining the rated current of the lighting device and the accuracy of the brightness of the lighting device; and determining the target current corresponding to the target brightness based on the rated current, accuracy, target brightness and a preset logarithmic mapping relationship.

[0098] For example, taking a base of 10 for the logarithm, the predefined logarithmic mapping relationship can be shown in the following formula:

[0099] B = 10^((C-1) / ((Cmax-1) / n))

[0100] Where Cmax represents the rated current; n is the brightness accuracy of the lighting equipment, expressed as a n The exponent n is used in the representation. For example... Figure 1e The diagram shows a preset logarithmic mapping relationship and a preset linear mapping relationship. The vertical axis represents the brightness expressed as a ratio (0-1000‰), and the horizontal axis represents the current of the lighting equipment, with a rated current of 1600mA.

[0101] In some embodiments, determining the target current corresponding to the target brightness includes: obtaining a preset scaling factor; and determining the target current corresponding to the target brightness based on the preset scaling factor, the target brightness, and a preset linear mapping relationship.

[0102] For example, a predefined linear mapping relationship can be represented by the following equation:

[0103] C = K * B

[0104] Where K represents the preset scaling factor. For example... Figure 1f The diagram shows a preset linear mapping relationship. The horizontal axis represents the brightness expressed as a ratio (0-1000‰), and the vertical axis represents the current of the lighting equipment, with a rated current of 1600mA.

[0105] 140. Update the target current based on the ambient light intensity to obtain the updated current.

[0106] In some embodiments, the updated current can be obtained using the following formula:

[0107] Y = C * X

[0108] Y represents the updated current; X represents the ratio of the current ambient light intensity. The ratio of ambient light intensity is the ratio of the current ambient light intensity to the maximum ambient light intensity. The maximum ambient light intensity can be the maximum threshold of the ambient light sensor or the ambient light intensity at noon in the environment where the projection device is located. This intensity can be determined through multiple data acquisitions. For example, if the maximum ambient light intensity is 3000 lm and the current ambient light intensity is 1800 lm, then the ratio of ambient light intensity is 60%, and X is 60%. In other words, the target current X is reduced by 60% to obtain the updated current Y.

[0109] 150. Based on the updated current and target color temperature, control the drive current of the lighting equipment associated with the projection device.

[0110] In some embodiments, the lighting equipment includes a cool light lamp device and a warm light lamp device, wherein the color temperature of the cool light lamp device and the warm light lamp device is not limited; for example, the color temperature of the warm light lamp device may be 2700K, and the color temperature of the cool light lamp may be 6500K. Based on the updated current and target color temperature, controlling the drive current of the lighting equipment associated with the projection device includes:

[0111] a) Determine the current ratio between the drive currents of the cool light lamp device and the warm light lamp device at the target color temperature.

[0112] Optionally, the current ratio f:g corresponding to the target color temperature can be determined from a preset color temperature-current ratio mapping relationship, where f represents the proportion of the driving current of the warm-colored lamp device, and g represents the proportion of the driving current of the cool-colored lamp device. The preset color temperature-current ratio mapping relationship can be obtained through actual measurements of the lighting equipment. For example, with a color temperature of 2700K for the warm-colored lamp device and 6500K for the cool-colored lamp device, the preset color temperature-current ratio mapping relationship can be shown in the table below:

[0113] Preset color temperature current ratio mapping relationship

[0114]

[0115]

[0116] b) Based on the current ratio and the updated current, determine the first current corresponding to the cold light lamp device and the second current corresponding to the warm light lamp device.

[0117] c) Control the driving current of the cold light lamp device to the first current, and control the driving current of the warm light lamp device to the second current.

[0118] 160. When the projection device is in the second working state, the driving current of the lighting device is controlled to be the current corresponding to the preset brightness and color temperature.

[0119] The second working state can be a movie viewing state, a screen casting state, etc.

[0120] The preset brightness and color temperature can be set by the user, obtained through analysis of historical usage data, or be the factory default brightness and color temperature. Optionally, the current corresponding to the preset brightness and color temperature can also be directly set. When the projection device is in the second working state, this current is directly acquired and the driving current of the lighting device is controlled to be this current.

[0121] In some embodiments, when the projection device is in a second working state or the user is in a target state, a target control command is generated; the target control command is sent to the target device to control the target device to be in the state indicated by the target control command. The target device can be a curtain, a screen, etc. For example, when the user is watching a movie, a closing control command can be sent to the curtain to control it to be closed, and an opening control command can be sent to the screen to lower it; a closing control command can also be sent to the curtain during the user's lunch break to control it to be closed, thus providing a better environment for the user's lunch break or movie watching.

[0122] As shown above, the lighting equipment can be controlled based on the projector's operating status, as well as the target brightness, target color temperature, and ambient light intensity of the environment at the current time. Therefore, this solution allows for the control of the lighting equipment's brightness and intensity according to different environments, times, and the projector's operating status, meeting the needs of different users without requiring constant adjustments, thus improving the user experience.

[0123] To better implement the above methods, this application also provides an intelligent control device. In this embodiment, the method of this application will be described in detail with the example of the intelligent control device being specifically integrated into a projection device.
