Description

Technical Field

[0001] The present disclosure relates to the field of lighting control, and more particularly, to a method, device, electronic device, and storage medium for controlling lighting. Background Art

[0002] Currently, voice-activated lights in public scenarios such as office spaces or dormitory corridors generally have problems with insensitive triggering mechanisms or unreasonable delays. For example, some voice-activated lights require a relatively high decibel sound to activate, and normal walking or quiet conversations are difficult to trigger the lighting. Especially in the late night or in a quiet environment, users are forced to deliberately create noise, which instead affects others. In addition, the delay-off time settings of some lamps are fixed and cannot adapt to different scenario requirements: short delays may cause the lighting to be interrupted frequently, while long delays are likely to result in the embarrassing situation of "always on when no one is there". If users need to carry items or stay briefly, they often need to repeatedly trigger the voice-activated switch, and the actual experience far from meets the original design intention of "seamless convenience".

[0003] Moreover, although voice-activated lights are sold as an energy-saving feature with "lights off when people leave", they often have hidden energy consumption due to technical defects in actual operation. On the one hand, the misjudgment rate of sensors is high. For example, environmental noise or activities in adjacent areas may accidentally trigger the switch, resulting in ineffective lighting. More seriously, to make up for the sensitivity problem, many places adopt a compromise solution of "high brightness + long delay", which instead doubles the energy consumption per single lighting. Data shows that the comprehensive electricity consumption of inferior voice-activated systems is even higher than the timed-switching mode of ordinary lamps, and the energy-saving promise becomes meaningless.

[0045] In all the examples shown and discussed here, any specific values should be construed as merely exemplary, rather than as limitations. Thus, other examples of the exemplary embodiments may have different values.

[0046] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, it is not necessary to discuss it further in subsequent figures.

[0047] It should be noted that all actions of obtaining signals, information, or data in the embodiments of the present disclosure are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where the location is located and obtaining authorization from the corresponding device owner.

[0048] In an example of this embodiment, a method for controlling lights is further provided. A detection device is provided on the door entering the target space. The detection device includes a device for detecting whether the corresponding door is opened and the target access control device carried by the user who opens the door, such as Figure 1 As shown, the method includes steps S11 - S13:

[0049] Step S11, when it is detected that the door is opened, taking the position corresponding to the door as the initial position and determining the target access control device carried by the user.

[0050] In the embodiments of the present application, the target space is the space to which the light control method is applied, and there are one or more lamps with different positions inside this space. In this example, the target space may be a public area such as an office or a dormitory corridor.

[0051] In the embodiments of the present application, when the user enters the target space, a detection device may be provided on or near the door entering the target space. The device may include various types of sensors as detection units. When the user opens the door, the sensors can detect that the door is opened and take the position of the door as the initial position of the user entering the target space.

[0052] In this example, the detection device may be an access control device or an intelligent door lock, etc. The sensors may include a pressure sensor provided on the doorknob, a camera sensor that captures the position of the door, or an identity verification sensor in the access control that interacts with the user, etc.

[0053] In this example, an authentication device can be set near the door of the target space to determine the user's identity. For example, an access control device that interacts with the user. The user can open the door by swiping a smart work ID card, a smart access control device, or other devices with access control functions. At the same time, the system can determine the user's identity based on this interaction behavior. Or, a wireless communication module such as Bluetooth, UWB, or NFC is set near the door. A wireless communication connection can be established with the corresponding access control device carried by the user to determine the access control device carried by the user, so as to open the door corresponding to entering the target space and determine the access control device at the same time.

[0054] Step S12: Turn on the first lamp in the target space. The lighting area of the first lamp corresponds to the initial position.

[0055] Step S13: Determine the user's position in the target space through the target access control device, and control the opening and closing of the lamps in the target space based on the position.

[0056] In one example, the target access control device carried by the user refers to a device with access control functions such as a smart work ID card, a smart access control device, a mobile phone, etc. Then, the user's position in the target space is determined through the access control device. For example, a positioning module can be built into the device to directly obtain the user's location. Another example is that the device and the target space can have a UWB positioning module, and the positioning function of UWB is used to realize the positioning of the user in the target space.

[0057] In this example, after determining the user's initial position, the lamp corresponding to the initial position of the lighting in the target space can be controlled to turn on, so as to provide lighting for the user. In the embodiments of the present application, the lighting area corresponding to each lamp inside the target space can be stored in advance. When there is someone in this area, the corresponding lamp is kept on. When there is no one in the corresponding area, the lamp in the corresponding area is turned off. In this example, the lighting areas corresponding to different lamps can have overlapping parts. Then, it can be determined whether the user's position is in the corresponding area. When the user enters the lighting area of a certain lamp, the corresponding lamp is turned on for lighting. When the user leaves the corresponding area, the corresponding lamp can be turned off to save power.

[0058] In this example, a method for controlling lighting is provided. When a user enters a target space, the detection device on the door can confirm the user's initial position when entering and the target access control device carried by the user, and turn on the lighting fixture corresponding to the initial position for illumination. After that, based on the user's target access control device, the user's position in the target space is determined, and the opening and closing of the lighting fixtures are controlled based on the user's position. In this way, after the user enters the target space, the lighting at the user's position can be automatically turned on without any operation by the user, and when the user is in the target space, the opening and closing of each lighting fixture are automatically controlled along with the user's position, solving the problems of poor convenience and energy-saving effect in traditional lighting control.

[0059] In an example of this embodiment, determining the user's position in the target space through the target access control device includes: controlling the target access control device to emit a sound signal with a target frequency, and determining the user's position in the target space according to the sound signal, where the target frequency is greater than the highest frequency that the human ear can hear.

[0060] In this example, the access control device can be controlled to continuously send out a sound signal with a target frequency higher than the highest frequency that the human ear can hear, such as a sound signal greater than 20 kHz, to determine the user's position. In this example, the user's mobile device can be controlled to emit an ultrasonic signal to determine the user's own position in the target space, and since the frequency of the sound signal is higher than the range that the human ear can hear, this method will not cause noise interference to the user and other people in other spaces.

[0061] In an example of this embodiment, one or more receiving devices are preset at different positions in the target space for receiving the sound signal with the target frequency and determining the position according to the sound signal, including: determining the number of receiving devices that receive the sound signal; in the case where the number is multiple, respectively obtaining the sending time of the sound signal and the receiving time of each receiving device, and determining the distance between the user and the receiving device according to the sending time, receiving time, and sound propagation speed, and determining the user's position according to the distance.

[0062] In an example of this embodiment, the receiving devices are installed one-to-one on the lighting fixtures in the target space, or the receiving devices are installed one-to-one on the inner side of the door entering the target space.

[0063] In this example, multiple receiving devices for receiving sound signals can be set at different positions in the target space. The receiving device can be provided with a microphone and a supporting circuit to sample the corresponding sound signal at a fixed frequency, such as 60 Hz. The receiving device can be turned on and sampled only after the user enters the target space. In one example, it can be as Figure 2As shown, a receiving device is provided on each lamp in the target space, and the sound signal emitted by the user's device is obtained through the receiving device on the lamp. In another example, the receiving device can be provided on the inner side of each door in the target space. Moreover, the position of each receiving device can be stored in advance so as to determine the position of the user in the target space based on the position of the receiving device subsequently.

[0064] In the embodiment of the present application, the position of the user can be determined according to the number of receiving devices that receive the sound signal.

[0065] In one example, when the number of receiving devices that receive the sound signal is multiple, such as two or more, the transmission time of the sound signal can be obtained from the user device side, and the reception time of the sound signal can be obtained from the receiving device. The relative distance between the two is determined by the product of the time difference and a factor. According to the distances between the user device and multiple receiving devices, the orientation of the user in the target space can be determined based on the pre-stored positions of the receiving devices. In this example, when three or more receiving devices receive the sound signal, three-point positioning can be achieved based on the positions and distances of these three devices, and the unique position of the user in the space can be obtained. When two receiving devices receive the sound signal, for example, as Figure 3 shown in the figure, a receiving device is provided on the door. The two receiving devices can be respectively provided at the positions of the door pointed by the dotted lines in the figure. Based on the positions of the two receiving devices and the distances between the user and these two receiving devices, it is possible to find the unique position of the user in the space, that is, the position of the black dot. However, it is also possible to find two positions, such as Figure 4 shown in the figure. In this case, the position relatively close to the position of the user in the previous sampling period can be used as the position of the user.

[0066] In one example of this embodiment, determining the position according to the sound signal includes: in the case of a single quantity, obtaining the transmission time of the sound signal and the reception time of the first receiving device, and determining the first distance between the user and the first receiving device according to the transmission time, the reception time, and the sound propagation speed. Based on the first position of the user in the previous sampling period and the first distance, the second position of the user in the current sampling period is determined.

[0067] In one example of this embodiment, determining the second position of the user in the current sampling period based on the first position of the user in the previous sampling period and the first distance includes: obtaining the third position of the first receiving device, and constructing a first circular area with the third position as the center and the distance between the user and the first receiving device in the current sampling period as the radius; taking the position closest to the first position in the first circular area as the second position.

[0068] In this example, the first distance between the user and the first receiving device can be determined based on the transmission time of the sound signal and the receiving time of the first receiving device, and according to the transmission time, the receiving time, and the sound propagation speed. However, when only one receiving device receives the sound signal, the specific position information of the user cannot be obtained solely based on the distance. At this time, a circular area can be constructed with the third position as the center and the distance as the radius, such as Figure 5 the dotted circular area shown, and the position of the circle closest to the position of the user in the previous sampling period ( Figure 5 the small white circle in) ( Figure 5 the black circle in) is used as the position of the user in the current period. In this example, the position of the user in each sampling period is cached until the user leaves the target space.

[0069] In this example, a method for determining the user's position is provided, which can determine the user's position in the space in different ways based on the number of receiving devices that receive the user's sound, so as to control the opening and closing of the lamps and handle various possible situations.

[0070] In an example of this embodiment, a UWB positioning module is provided on the target access control device, and at least two UWB positioning devices are provided in the target space. Determining the position of the user in the target space through the target access control device includes: controlling the UWB positioning module to broadcast a UWB signal; determining the time difference between the receiving time and the transmitting time of the UWB signal received by at least two UWB positioning devices; determining the distance between the UWB positioning module and the UWB positioning device, where the distance is half of the product of the time difference and the speed of light; and determining the position of the user in the target space based on the distances between the UWB positioning module and at least two UWB positioning devices.

[0071] In this embodiment, the installation positions of the UWB positioning devices can be similar to those of the receiving devices, and they can be installed one by one on the lamps in the target space or on the inner side of the door entering the target space. The access control device carried by the user can also have a UWB positioning module, which serves as a UWB positioning tag to perform positioning with the UWB positioning devices in the space. In this example, the transmission time of the UWB signal broadcast by the UWB positioning module and the receiving time when the UWB positioning device receives the signal can be determined respectively to determine the time difference. Then, based on TOF (Time of Flight), the distances between the target access control device and the two UWB positioning devices are determined, where the distance is half of the product of the time difference and the speed of light, so as to determine the position of the target access control device in the space, so as to control the opening or closing of the lamps based on this position subsequently.
