[0052] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0053] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0055] First, some nouns involved in this application are analyzed:

[0056] Infrared pair tube: It includes infrared transmitting tube and infrared receiving tube, where the infrared transmitting tube is used to transmit infrared rays and the infrared receiving tube is used to receive infrared rays. When the infrared pair tube detects an object, its output voltage will change. This voltage change can be detected by a microcontroller (also called a microcontroller unit, Microcontroller Unit, MCU) or other electronic devices, thereby realizing the detection of objects or the measurement of distance.

[0057] Bathroom mirror cabinet: a type of bathroom furniture that combines the functions of a mirror and a storage cabinet. Bathroom mirror cabinets can be equipped with lighting equipment, such as LED light strips.

[0058] The lighting control method for a bathroom mirror cabinet, the controller, the bathroom mirror cabinet, and the medium provided in the embodiments of the present application are specifically described through the following embodiments. First, the lighting control method for a bathroom mirror cabinet in the embodiments of the present application is described.

[0059] Figure 1 is an optional flow chart of a lighting control method for a bathroom mirror cabinet provided in an embodiment of the present application. Figure 1 The method may include but is not limited to steps 101 to 104.

[0060] Step 101, obtaining an environmental exposure value and an environmental non-exposure value;

[0061] Step 102, performing difference calculation based on the environmental exposure value and the environmental non-exposure value to obtain an environmental transformation difference;

[0062] Step 103, comparing the environment change difference at the first moment with the target environment change judgment threshold to obtain a change difference comparison result; wherein the change difference comparison result includes a first result, the first result is that the environment change difference at the first moment is greater than the target environment change judgment threshold, the target environment change judgment threshold is obtained by updating the preset initial environment change judgment threshold based on the environment change difference at the second moment, and the first moment is later than the second moment;

[0063] Step 104: Perform a light on / off switching operation according to the first result.

[0064] The beneficial effects of the embodiments of the present application include but are not limited to: updating the target environment change judgment threshold by the environment change difference at the second moment, thereby updating the target environment change judgment threshold in real time based on the lighting conditions of the environment where the bathroom mirror cabinet is located; and using the updated target environment change judgment threshold to judge whether the environment change difference at the first moment is greater than the target environment change judgment threshold. If the environment change difference is greater than the target environment change judgment threshold, a light on / off switching operation is performed, so that the light of the bathroom mirror cabinet can be controlled in different lighting environments, thereby improving the accuracy and universality of the light control method of the bathroom mirror cabinet.

[0065] In step 101 of some embodiments, the ambient exposure value and the ambient non-exposure value can be obtained through the light detection module. Specifically, the light detection module is deployed in the bathroom mirror cabinet, and the light detection module can be an infrared pair tube, such as a digital infrared pair tube, wherein the digital infrared pair tube includes an infrared transmitting tube and an infrared receiving tube, wherein the infrared transmitting tube is used to transmit infrared rays, and the infrared receiving tube is used to receive infrared rays. Therefore, the ambient light can be detected by the digital infrared pair tube to obtain the ambient exposure value and the ambient non-exposure value. Among them, the ambient light refers to the lighting state around the bathroom mirror cabinet. The ambient exposure value and the ambient non-exposure value can also be obtained by other means, not limited to this.

[0066] It should be noted that exposure refers to the infrared emitting tube emitting infrared light, and non-exposure refers to the infrared emitting tube not emitting infrared light. The environmental exposure value refers to the energy value detected by the infrared receiving tube when the infrared emitting tube is exposed (emitting infrared light); the environmental non-exposure value refers to the energy value detected by the infrared receiving tube when the infrared emitting tube is not exposed (not emitting infrared light).

[0067] It should be noted that the environment in which the bathroom mirror cabinet is located will affect the ambient exposure value and the ambient non-exposure value. For example, in one application example, the bathroom mirror cabinet is set above a smooth ceramic wash basin, and ceramics can reflect light very well. Therefore, the light intensity detected by the light detection module on the bathroom mirror cabinet is relatively large, resulting in a relatively large ambient non-exposure value. In another application example, the bathroom mirror cabinet is set on a rough stone wash basin, and the light intensity refracted by the stone wash basin is relatively small, or the light around the bathroom mirror cabinet is relatively dark, resulting in a relatively small light intensity detected by the light detection module, which in turn results in a relatively small ambient non-exposure value.

[0068] In some embodiments, the environmental exposure value and the environmental non-exposure value can be periodically obtained according to a preset polling interval. The polling interval can be the interval time for the digital infrared tube to detect the illumination state, such as collecting the environmental exposure value and the environmental non-exposure value every 0.1s (seconds). The exposure time of the digital infrared tube can also be initialized. The exposure time refers to the time for the infrared transmitting tube of the digital infrared tube to emit infrared light. The longer the exposure time, the greater the light intensity received by the infrared receiving tube, and the greater the environmental exposure value. Therefore, when the environmental exposure value is too small (for example, less than a preset exposure intensity lower limit threshold), the exposure time can be increased, such as increasing the exposure time by a preset unit time length, and the unit time length can specifically be 0.5ms (milliseconds).

[0069] Specifically, the environmental exposure value and the environmental non-exposure value may be standardized values ​​without units. The digital infrared tube may store the environmental exposure value and the environmental non-exposure value in an internal register, and the MCU reads the environmental exposure value and the environmental non-exposure value from the internal memory to calculate the difference between the environmental exposure value and the environmental non-exposure value.

[0070] In step 102 of some embodiments, the difference calculation is performed according to the environmental exposure value and the environmental non-exposure value, and the absolute value of the difference between the environmental exposure value and the environmental non-exposure value can be calculated. It should be noted that the environmental transformation difference is used to characterize the difference between the environmental exposure value and the environmental non-exposure value, and the size of the environmental transformation difference can be used to determine whether the user has made a light shielding action (such as a hand sweeping action, or using a hand to approach the detection area corresponding to the light detection module of the bathroom mirror cabinet). For example, when the infrared transmitting tube is exposed (emitting infrared light), if the infrared rays emitted by the infrared transmitting tube are blocked by an object, the light intensity received by the infrared receiving tube is weakened, resulting in a higher output voltage of the infrared receiving tube, which is usually expressed as a high level (for example, the voltage of the power supply connected to the digital infrared pair tube), resulting in a larger value of the environmental exposure value, and then the environmental transformation difference is larger. If there is no object blocking the infrared rays, the output voltage of the infrared receiving tube is low, which is usually expressed as a low level (such as 0V to 0.5V), resulting in a smaller value of the environmental exposure value, and then the environmental transformation difference is small. In addition, the environmental non-exposure value is mainly affected by the ambient light around the bathroom mirror cabinet. Since the intensity of ambient light is weaker than the intensity of infrared light emitted by the infrared emitting tube, when the infrared emitting tube is not exposed, if there is an object blocking the light, the ambient non-exposure value will increase, but the degree of increase in the ambient non-exposure value is much smaller than the ambient exposure value. It can be seen that when there is an object blocking the infrared light, the difference in ambient change is larger; when there is no object blocking the infrared light, the difference in ambient change is smaller.

[0071] In step 103 of some embodiments, the transformation difference comparison result indicates that the environment transformation difference is greater than the target environment transformation judgment threshold, or indicates that the environment transformation difference is less than or equal to the target environment transformation judgment threshold. It should be noted that the target environment transformation judgment threshold is obtained by updating the preset initial environment transformation judgment threshold based on the environment transformation difference at the second moment. The specific updating process includes: after obtaining the environment exposure value and the environment non-exposure value at the second moment and calculating the environment transformation difference, the initial environment transformation judgment threshold is updated with the environment transformation difference at the second moment to obtain the target environment transformation judgment threshold. Then, after a period of time (for example, after a polling interval), at the first moment, the environment exposure value and the environment non-exposure value are obtained and the environment transformation difference at the first moment is calculated, and the target environment transformation judgment threshold updated at the second moment is compared with the environment transformation difference at the first moment to obtain the transformation difference comparison result. Since the environment transformation difference at the second moment is the difference between the environment exposure value and the environment non-exposure value, it can reflect the lighting state of the environment. Therefore, by updating the target environment transformation judgment threshold by the environment transformation difference at the second moment, the target environment transformation judgment threshold can be updated in time when the environment changes. In this way, this embodiment is applicable to different lighting environments, thereby improving the accuracy and universality of the lighting control method for the bathroom mirror cabinet.

[0072] In step 104 of some embodiments, a light on / off switching operation is performed according to the first result. That is, if the environment change difference at the first moment is greater than the target environment change judgment threshold, the lighting module of the bathroom mirror cabinet is controlled to be in a light-on state or a light-off state. The lighting module may be a light strip or an LED (light emitting diode) lamp bead.

[0073] It should be noted that if the environment change difference is greater than the target environment change judgment threshold, it means that there is a shading action, so the light on / off switching operation is performed. Performing the light on / off switching operation means that if the lighting module of the bathroom mirror cabinet is in the light-on state, the lighting module is switched from the light-on state to the light-off state; if the lighting module of the bathroom mirror cabinet is in the light-off state, the lighting module is switched from the light-off state to the light-on state.

[0074] See also Figure 2 In some embodiments, after step 103, the lighting control method for a bathroom mirror cabinet may further include but is not limited to steps 201 to 202:

[0075] Step 201, obtaining the number of first results to obtain a first target number;

[0076] Step 202: If the first target quantity is greater than a preset quantity threshold, a light brightness adjustment operation is performed.

[0077] The advantage of this embodiment is that, when the obtained transformation difference comparison result continues to be the first result, the number of the first results is obtained to obtain the first target number, and the first target number is compared with a preset number threshold. If the first target number is greater than the preset number threshold, a light brightness adjustment operation is performed, thereby being able to control the light brightness of the bathroom mirror cabinet and improving the flexibility of the light control method.

[0078] In step 201 of some embodiments, the number of first results obtained refers to the number of first results obtained when the transformation difference comparison results in the continuous time period are all the first results. For example, the transformation difference comparison result obtained at time t1 is the first result, and after a polling interval, the transformation difference comparison result obtained at time t2 is also the first result. In this way, if the measurement is performed continuously for 5 times and the transformation difference comparison result obtained each time is also the first result, the number of first results is 5.

[0079] In step 202 of some embodiments, if the first target quantity is greater than a preset quantity threshold, it can be determined that a continuous shading action is detected. For example, the quantity threshold is 9, and if a transformation difference comparison result is obtained every 0.1 seconds, 10 transformation difference comparison results are obtained in succession. If each transformation difference comparison result is the first result, it means that the manual shading action lasted for 1 second, and the first target quantity is 10. Since the first target quantity is 10 and is greater than the quantity threshold of 9, a light brightness adjustment operation can be performed. It should be noted that the light brightness adjustment operation can be performed by adjusting between preset light brightness gears, such as adjusting the state of the lighting module of the bathroom mirror cabinet from the first light gear to the second light gear. The light intensity corresponding to the second light gear is greater than the light intensity corresponding to the first light gear.

[0080] In some embodiments, when performing the light brightness adjustment operation, the lighting module is in a light-on state.

[0081] See also Figure 3 In some embodiments, before step 103, the lighting control method for a bathroom mirror cabinet may also include but is not limited to steps 301 to 302:

[0082] Step 301, calculating the average value of the environmental change difference of at least two consecutive historical moments to obtain the historical average environmental difference value; the at least two historical moments include the second moment;

[0083] Step 302: Update the initial environment change judgment threshold according to the historical average environment difference to obtain the target environment change judgment threshold.

[0084] The advantage of this embodiment is that the initial environment change judgment threshold is updated by the average value of the environment change difference at multiple consecutive moments, thereby eliminating the deviation of the single calculated environment change difference as much as possible, obtaining a more reliable historical average environment difference, and using the historical average environment difference to update the initial environment change judgment threshold, thereby improving the reliability of the target environment change judgment threshold obtained after the update.

[0085] In step 301 of some embodiments, at least two consecutive historical moments, wherein consecutive means that there is only a polling interval between the two historical moments. For example, the polling interval is 0.5 seconds, and polling is performed every 0.5 seconds. First, the environmental exposure value and the environmental non-exposure value are obtained at time t1 and the environmental change difference Q1 is calculated, and at time t2 after 0.5 seconds, the environmental change difference Q2 is calculated again, and so on, the environmental change difference is calculated every 0.5 seconds until time t128, and the environmental change difference Q128 is calculated, and the environmental change difference of 128 consecutive historical moments can be obtained. Then, the average value of the 128 environmental change differences is calculated to obtain the historical average environmental difference Qp=(Q1+Q2+…+Q128) / 128. Finally, the initial environmental change judgment threshold is updated according to the historical average environmental difference Qp.

[0086] In step 302 of some embodiments, the initial environment change judgment threshold is updated according to the historical average environment difference value. Specifically, the historical average environment difference value may be determined as the initial environment change judgment threshold value, or the historical average environment difference value and the initial environment change judgment threshold value may be weightedly calculated to obtain the updated target environment change judgment threshold value. The target environment change judgment threshold value may also be calculated in other ways, without limitation thereto.

[0087] See also Figure 4 In some embodiments, step 302 may include but is not limited to steps 401 to 402:

[0088] Step 401, performing weighted calculation based on the historical average environment difference and the initial environment change judgment threshold to obtain an environment change judgment weighted value;

[0089] Step 402: determine the environment change judgment weighted value as the target environment change judgment threshold.

[0090] The advantage of this embodiment is that the target environment change judgment threshold is calculated by a weighted sum method, which can improve the accuracy of the target environment change judgment threshold, thereby improving the accuracy of the lighting control method of the bathroom mirror cabinet.

[0091] In step 401 of some embodiments, the weighted calculation may specifically be a weighted average calculation.

[0092] In step 402 of some embodiments, the target environment change judgment threshold is an environment change judgment threshold used for comparison with the environment change difference at the next moment (a moment after a polling interval time).

[0093] In some embodiments, before step 101, the light control method for a bathroom mirror cabinet may further include:

[0094] Initialize the initial environment change judgment threshold;

[0095] Wherein, initializing the initial environment change judgment threshold may specifically include:

[0096] Initialize the polling interval;

[0097] At each polling interval, the initial environment non-exposure value and the initial environment exposure value are obtained;

[0098] Calculate the average value of the initial environment non-exposure values ​​of the second target number to obtain the initial environment non-exposure average value;

[0099] Calculate the average value of the initial environmental exposure values ​​of the second target number to obtain an average value of the initial environmental exposure;

[0100] The initial environment change judgment threshold is obtained by performing a difference calculation based on the initial environment non-exposure average value and the initial environment exposure average value.

[0101] The advantage of this embodiment is that, at each polling interval, the initial environment non-exposure value and the initial environment exposure value are obtained; the initial environment non-exposure average value is obtained according to the average value of the initial environment non-exposure values ​​of the second target number; and the initial environment exposure average value is obtained according to the average value of the initial environment exposure values ​​of the second target number, so that the initial environment change judgment threshold can be calculated according to the difference between the initial environment non-exposure average value and the initial environment exposure average value, and the initial environment change judgment threshold is initialized. In the embodiment of the present application, the initial environment change judgment threshold is initialized according to the surrounding environment of the bathroom mirror cabinet, thereby improving the accuracy of the initial environment change judgment threshold, thereby improving the accuracy of the target environment change judgment threshold obtained by subsequent updates.

[0102] It should be noted that the second target number may be any positive integer, such as 32. The polling interval may range from 0.05 to 1 second.

[0103] See also Figure 5 In some embodiments, after step 101, the lighting control method for a bathroom mirror cabinet may include but is not limited to steps 501 to 502:

[0104] Step 501, comparing the ambient non-exposure value with a preset light intensity threshold to obtain a light intensity comparison result;

[0105] Step 502, if the light intensity comparison result is that the ambient non-exposure value is less than the light intensity threshold, increase the preset light sensitivity to obtain an updated light sensitivity; wherein the light sensitivity is used to characterize the minimum detection light intensity of the light detection module, and the light detection module is used to detect the ambient exposure value and the ambient non-exposure value.

[0106] The advantage of this embodiment is that a light intensity comparison result is obtained by comparing the ambient non-exposure value with a preset light intensity threshold, and the light sensitivity is updated according to the light intensity comparison result, so as to adapt to the numerical values ​​of the ambient exposure value and the ambient non-exposure value detected by the light detection module, thereby improving the universality of the lighting control method and being applicable to different lighting environments.

[0107] It should be noted that the minimum detection light intensity refers to the minimum light intensity that the light detection module can detect. The greater the light sensitivity, the smaller the minimum detection light intensity. If the light intensity comparison result is that the ambient non-exposure value is less than the light intensity threshold, it means that the light in the environment where the bathroom mirror cabinet is located is weak. Therefore, increasing the light sensitivity can more accurately obtain the ambient non-exposure value, so that the light sensitivity can be adjusted according to the environment.

[0108] In step 501 of some embodiments, the light intensity comparison result may indicate that the ambient non-exposure value is less than the light intensity threshold, or that the ambient non-exposure value is greater than or equal to the light intensity threshold.

[0109] In step 502 of some embodiments, increasing the preset light sensitivity may be increasing the light sensitivity by a preset sensitivity unit value. The sensitivity unit value may be any positive real number, which is not limited in the embodiments of the present application. Specifically, the light sensitivity may be expressed in mW / sr, where mW / sr represents the power per unit area within a unit solid angle (sr for short), i.e., the power per square meter per solid angle is how many milliwatts (mW for short).

[0110] The embodiment of the present application further provides a controller, the controller includes a memory and a processor, the memory stores a computer program, and the processor implements the above-mentioned light control method for bathroom mirror cabinet when executing the computer program. Specifically, the controller can be an MCU. The controller can also include any intelligent terminal such as a tablet computer, a car computer, etc.
