Description

Technical Field

[0001] This invention relates to the field of light-controlled lamps, specifically to a method and system for synchronously controlling multiple light-controlled lamps. Background Technology

[0002] The light-controlled lamp can automatically turn on and off according to changes in ambient brightness. It uses a built-in photosensitive sensor to collect the ambient brightness and a processor to determine whether the ambient brightness is less than a preset threshold. If it is less than the preset threshold, the processor activates the lamp's circuit and turns on the lamp.

[0003] In some locations, such as corridors and lobbies, where the space is large, multiple light-controlled lights need to be installed simultaneously for illumination. Due to differences in the sensitivity of photosensitive sensors, when multiple light-controlled lights are under the same ambient brightness, the data output by their photosensitive sensors may differ. Furthermore, the brightness data detected by the photosensitive sensors may vary depending on their installation position within the same space. When multiple light-controlled lights illuminate the same area simultaneously, they may not be able to turn on or off at the same time, resulting in significant differences in the timing of switching on and off, severely impacting user experience.

[0004] The purpose of this invention is to design a method and system for synchronous control of multiple light-controlled lamps, addressing the problems existing in the prior art. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention provides a method and system for synchronous control of multiple light-controlled lamps, which can effectively solve at least one of the problems existing in the prior art.

[0006] The technical solution of this invention is:

[0007] A method for synchronously controlling multiple light-controlled lamps includes the following steps:

[0008] Install multiple light-controlled lamps in their respective positions, and fix the position and orientation of the photosensitive sensor of each light-controlled lamp;

[0009] The obstruction between each photosensitive sensor and the outdoor light is fixed, so that the coefficient of change of outdoor light propagating to each photosensitive sensor is fixed.

[0010] When multiple light-controlled lights are set, the indoor brightness is adjusted to the target brightness that requires the light-controlled lights to be turned on, and each light-controlled light is driven to collect the current brightness through the photosensitive sensor. Each light-controlled light stores its own current brightness as a brightness threshold.

[0011] When the multiple light-controlled lamps are working, each light-controlled lamp collects real-time brightness and compares the real-time brightness with the corresponding brightness threshold. When the real-time brightness is less than the brightness threshold, the light-controlled lamp is turned on.

[0012] Furthermore, the obstruction includes one or more of curtains, furniture, and decorations;

[0013] The means of fixing the obstruction between each photosensitive sensor and outdoor light includes: fixing the shape of the curtain; and / or fixing the placement of the furniture; and / or fixing the placement and orientation of the decorations;

[0014] The method of fixing the variation coefficient of outdoor light propagating to each of the photosensitive sensors includes fixing the influence of the obstruction on the outdoor light when it propagates indoors, thereby fixing the variation coefficient between the data received by the photosensitive sensor and the outdoor brightness data.

[0015] Furthermore, adjusting the indoor brightness to achieve the target brightness required to turn on the light-controlled lamp includes:

[0016] The light is diffused and illuminated at the center of the room, and the brightness of the diffused light is adjusted so that the average brightness of the room reaches the target brightness required to turn on the light-controlled lamp.

[0017] Furthermore, adjusting the indoor brightness to achieve the target brightness required to turn on the light-controlled lamp includes:

[0018] By illuminating the room with natural light, we wait for the average brightness of the room to change naturally and reach the target brightness required to turn on the light-controlled lights.

[0019] Furthermore, adjusting the indoor brightness to achieve the target brightness required to turn on the light-controlled lamp includes:

[0020] Obtain the angle of sunlight shining into the room at sunset, and then direct sunlight shines into the room from the outside at the angle of sunlight shining into the room at sunset, so that the average brightness of the room changes naturally and reaches the target brightness that requires turning on the light-controlled lights.

[0021] Furthermore, the light control lamp includes a storage module, and each light control lamp stores its current brightness as a brightness threshold in the corresponding storage module. When the light control lamp is powered on, it automatically reads the brightness threshold in the storage module.

[0022] Furthermore, the light control lamp includes a human-computer interaction module;

[0023] When multiple light-controlled lights are set, the human-computer interaction module obtains human-computer interaction instructions and starts driving each light-controlled light to collect the current brightness through the photosensitive sensor.

[0024] Furthermore, after each of the light-controlled lamps stores its current brightness as a brightness threshold, the following steps are executed:

[0025] The light-controlled lamp flashes as a signal to the user that storage is complete.

[0026] A system for synchronously controlling multiple light-controlled lamps, the system comprising multiple light-controlled lamps, each light-controlled lamp including a storage module, a processing module, a photosensitive sensor, and a lamp fixture; the storage module is used to store the brightness threshold of the corresponding light-controlled lamp; the processing module is used to compare the real-time brightness collected by the photosensitive sensor with the corresponding brightness threshold; when the real-time brightness is less than the brightness threshold, the corresponding lamp fixture is lit.

[0027] The system includes a brightness threshold adjustment mode and a working mode.

[0028] The brightness threshold adjustment mode is used to drive each of the light-controlled lamps to collect the current brightness through the photosensitive sensor when multiple light-controlled lamps are set, and each light-controlled lamp stores its own current brightness as a brightness threshold.

[0029] The working mode is used so that when the multiple light-controlled lights are working, each light-controlled light collects real-time brightness and compares the real-time brightness with the corresponding brightness threshold. When the real-time brightness is less than the brightness threshold, the light-controlled light is turned on.

[0030] Therefore, the present invention provides the following effects and / or advantages:

[0031] This invention addresses the problem of inconsistent light switching times caused by electronic component errors or inconsistent sensor installation positions. It achieves synchronization through the above operations, thereby resolving the inconsistency. The set value for the light switching point can be reset and changed via a switch reset, without requiring additional input devices.

[0032] This invention fixes the position and orientation of the photosensitive sensor of each light-controlled lamp, and fixes the obstruction between each photosensitive sensor and the outdoor light, so that the change coefficient of outdoor light propagating to each photosensitive sensor is fixed. Therefore, when collecting photosensitive data, each light-controlled lamp can obtain data with a fixed change coefficient, and each light-controlled lamp can determine its own switching threshold, thereby achieving the technical effect of synchronously turning on the lamps at the target brightness.

[0033] It should be understood that the above summary and the following detailed description of the invention are exemplary and explanatory, and are intended to provide further explanation of the invention as claimed. Attached Figure Description

[0034] Figure 1This is a schematic diagram of the method flow of one embodiment of the present invention. Detailed Implementation

[0035] To facilitate understanding by those skilled in the art, the structure of the present invention will now be described in further detail with reference to the accompanying drawings:

[0036] refer to Figure 1 A method for synchronously controlling multiple light-controlled lamps includes the following steps:

[0037] S1, Install multiple light-controlled lamps in their respective positions, and fix the position and orientation of the photosensitive sensor of each light-controlled lamp;

[0038] In this embodiment, the installation positions of the multiple light-controlled lamps are fixed, such as a fixed position on the ceiling. Simultaneously, the position and orientation of the photosensitive sensors for the light-controlled lamps are also fixed, such as a fixed position on the wall and a specific orientation. Preferably, the photosensitive sensors face the window because the window serves as the light inlet for natural light into the room, and the window itself should be located in a well-lit area. This orientation allows the photosensitive sensor to directly receive and determine the brightness of natural light. Furthermore, since opening and closing doors and movement of people can easily interfere with natural light indoors, this orientation minimizes interference from changes in indoor light.

[0039] By fixing the position and orientation of the photosensitive sensor of each light-controlled lamp, multiple photosensitive sensors can acquire fixed brightness data at the same time or under the same ambient light intensity. This fixed brightness data can be used for subsequent judgment.

[0040] S2, fix the obstruction between each photosensitive sensor and the outdoor light, so that the change coefficient of outdoor light propagating to each photosensitive sensor is fixed;

[0041] Because there may be obstructions between the photosensor and outdoor light, such as curtains, furniture, and decorations, the placement and orientation of the furniture may interfere with the transmission of outdoor light. Decorations, such as mirrors and vases, may reflect and refract light in different ways. Therefore, this step fixes the obstructions. Under the same outdoor light conditions, the variation coefficient of light propagating to each photosensor will be minimized when the obstructions are fixed. Thus, the brightness data sensed by each photosensor will be consistent at subsequent times or under the same ambient light intensity.

[0042] S3, when multiple light-controlled lamps are set, the indoor brightness is adjusted to the target brightness that requires the light-controlled lamps to be turned on, and each light-controlled lamp is driven to collect the current brightness through the photosensitive sensor. Each light-controlled lamp stores its own current brightness as a brightness threshold.

[0043] This step is the core step of this application. The background technology mentions that when multiple light-controlled lamps are under the same ambient brightness, the data output by their photosensitive sensors may differ, and even within the same space, different installation positions of the photosensitive sensors will result in different brightness data detected by the sensors. This step can solve these two problems.

[0044] First, the indoor brightness is controlled to reach the target brightness required to turn on the light-controlled lights; at this point, the indoor brightness is fixed. Because the orientation and position of the photosensitive sensors are fixed as described above, the brightness data sensed by each photosensitive sensor remains constant over a subsequent period when the indoor brightness reaches the target brightness. For example, if the brightness data sensed by photosensitive sensor 1 at the target brightness is 35 after analog-to-digital conversion, then the next time photosensitive sensor 1 senses brightness data at the target brightness, after analog-to-digital conversion, it will also be 35. Similarly, if the brightness data sensed by photosensitive sensor 2 at the target brightness is 34 after analog-to-digital conversion, then the next time photosensitive sensor 2 senses brightness data at the target brightness, after analog-to-digital conversion, it will also be 34. In other words, the external influence on the light reaching the photosensitive sensors is constant; for example, factors such as obstruction, scattering, diffraction, and refraction mean that the data received by each photosensitive sensor at each target brightness is fixed at different times. Therefore, this step can eliminate the existing technical defect that causes different lights to be on at the same time because the brightness data detected by the photosensitive sensors are different depending on the installation position of the photosensitive sensors in the same space.

[0045] Furthermore, assuming the user's requirement is for the lights to automatically turn on when the ambient light intensity is below 150 lm, the AD value sampled by the photosensor at this time is 30, and the threshold set by the existing execution method is 30. Given three lamps A, B, and C, when the ambient light dims to 150 lm, due to differences in the internal components of the light controller and the sensor installation position, the AD value sampled by the MCU of lamp A is 29, that of lamp B is 30, and that of lamp C is 31. However, the program-set threshold is 30. Clearly, lamp A has not yet switched states, lamp B is switching, and lamp C has already switched ahead of schedule. This inconsistent state switching between lamps severely impacts the user experience.

[0046] The steps of this application involve placing N light-controlled lamps that need to be synchronized in fixed positions and synchronizing them at the required switching time (e.g., when the ambient brightness is 150 lm). Simultaneously, a trigger signal is sent to each of the N light-controlled lamps (e.g., switching 5 times within 5 seconds on a wall switch, or triggering the switch by pressing and holding a button). The lamps flash to indicate to the user that the trigger signal has been successfully activated. At this moment, all the light-controlled lamps simultaneously sample the ambient brightness value via the MCU. Therefore, this step allows for setting an activation threshold for each light-controlled lamp, enabling synchronized lighting of all lamps, even when there are differences in the data collected by the photosensitive sensors in existing technologies.

[0047] S4, when the plurality of light-controlled lamps are working, each light-controlled lamp collects real-time brightness and compares the real-time brightness with the corresponding brightness threshold. When the real-time brightness is less than the brightness threshold, the light-controlled lamp is turned on.

[0048] This step can be implemented as follows: the MCU writes its sampled values ​​into flash memory for storage (these values ​​are not lost when power is off); each time a lamp is powered on, the MCU reads the value stored in its flash memory and uses this value as the setting value for determining whether to turn the lamp on or off. After synchronization using the above method, when the ambient light dims to 150lm, the MCU of lamp A samples an AD value of 29, the MCU of lamp B samples an AD value of 30, and the MCU of lamp C samples an AD value of 31. Since lamps A, B, and C have already written their sampled AD values ​​into flash memory during the previous synchronization operation and used these values ​​as their respective switching thresholds, the switching thresholds for lamps A, B, and C are 29, 30, and 31, respectively. When the ambient light dims to 150lm, lamps A, B, and C will turn on simultaneously.

[0049] Furthermore, the obstruction includes one or more of the following: curtains, furniture, and decorations;

[0050] The means of fixing the obstruction between each photosensitive sensor and outdoor light includes: fixing the shape of the curtain; and / or fixing the placement of the furniture; and / or fixing the placement and orientation of the decorations;

[0051] The method of fixing the variation coefficient of outdoor light propagating to each of the photosensitive sensors includes fixing the influence of the obstruction on the outdoor light when it propagates indoors, thereby fixing the variation coefficient between the data received by the photosensitive sensor and the outdoor brightness data.

[0052] This step fixes the placement direction, position, type, and quantity of items along the path of outdoor light to each photosensitive sensor. In other words, it fixes the influence of the indoor environment on the transmission of light to the photosensitive sensor. After the light-controlled lamp records a certain set value, the influence of the outside environment on the light is fixed, avoiding the impact caused by the addition of obstructions or changes in the position of furniture or decorations when the outside light reaches the set value next time. It also fixes the coefficient of variation between the data received by the photosensitive sensor and the outdoor brightness data.

[0053] Furthermore, adjusting the indoor brightness to achieve the target brightness required to turn on the light-controlled lamp includes:

[0054] The light is diffused and illuminated at the center of the room, and the brightness of the diffused light is adjusted so that the average brightness of the room reaches the target brightness required to turn on the light-controlled lamp.

[0055] This step adjusts the indoor light brightness from the center of the room. Light-controlled lights can be fire emergency lights, etc. Under natural conditions, indoor light is generally diffused light; therefore, adjusting the brightness of the diffused light from the center of the room controls the overall brightness, allowing each light-controlled light to sense this brightness level and set it as the target brightness. This step can quickly achieve the target brightness required to turn on the light-controlled lights.

[0056] Furthermore, the light control lamp includes a storage module, and each light control lamp stores its current brightness as a brightness threshold in the corresponding storage module. When the light control lamp is powered on, it automatically reads the brightness threshold in the storage module.

[0057] Furthermore, the light control lamp includes a human-computer interaction module;

[0058] When multiple light-controlled lights are set, the human-computer interaction module obtains human-computer interaction instructions and starts driving each light-controlled light to collect the current brightness through the photosensitive sensor.

[0059] In this embodiment, the human-computer interaction module can be a button, screen, voice control, etc. It is used to acquire commands input by the operator, switch the light-controlled lamps to the setting mode, and thus begin driving each light-controlled lamp to collect its current brightness through the photosensor.

[0060] Furthermore, after each of the light-controlled lamps stores its current brightness as a brightness threshold, the following steps are executed:

[0061] The light-controlled lamp flashes as a signal to the user that storage is complete.

[0062] Furthermore, a system for synchronously controlling multiple light-controlled lamps is provided. The system consists of multiple light-controlled lamps, each of which includes a storage module, a processing module, a photosensitive sensor, and a lamp. The storage module is used to store the brightness threshold of the corresponding light-controlled lamp, and the processing module is used to compare the real-time brightness collected by the photosensitive sensor with the corresponding brightness threshold. When the real-time brightness is less than the brightness threshold, the corresponding lamp is lit.

[0063] The system includes a brightness threshold adjustment mode and a working mode.

[0064] The brightness threshold adjustment mode is used to drive each of the light-controlled lamps to collect the current brightness through the photosensitive sensor when multiple light-controlled lamps are set, and each light-controlled lamp stores its own current brightness as a brightness threshold.

[0065] The working mode is used so that when the multiple light-controlled lights are working, each light-controlled light collects real-time brightness and compares the real-time brightness with the corresponding brightness threshold. When the real-time brightness is less than the brightness threshold, the light-controlled light is turned on.

[0066] The working principle of a system for synchronously controlling multiple light-controlled lamps is basically the same as that of a method for synchronously controlling multiple light-controlled lamps, and will not be elaborated here.

[0067] Example 2

[0068] Furthermore, adjusting the indoor brightness to achieve the target brightness required to turn on the light-controlled lamp includes:

[0069] By allowing natural light to illuminate the room, the average brightness of the room changes naturally until it reaches the target brightness required to turn on the light-controlled lights.

[0070] This embodiment is basically the same as Embodiment 1, except that this step adjusts the average indoor brightness using natural light. For example, it can be set to adjust the average indoor brightness naturally at the local sunset time to achieve the target brightness required to turn on the light-controlled lights. This step allows for simple setting of the target brightness without the need for external tools.

[0071] Example 3

[0072] Furthermore, adjusting the indoor brightness to achieve the target brightness required to turn on the light-controlled lamp includes:

[0073] Obtain the angle of sunlight shining into the room at sunset, and then direct sunlight shines into the room from the outside at the angle of sunlight shining into the room at sunset, so that the average brightness of the room changes naturally and reaches the target brightness that requires turning on the light-controlled lights.

[0074] This embodiment is essentially the same as Embodiment 1, except that in rooms with less building obstruction, such as those by the sea, on mountaintops, or in plazas, the scattered light from the surrounding environment is reduced, and most of the light is direct sunlight. Therefore, at sunset, sunlight shines directly into the room, and the angle of direct sunlight is within a certain range. This step combines the recorded indoor light intensity and the angle of sunlight at sunset to simulate the outdoor light that produces that intensity, thus setting the target brightness. This allows for precise control of the indoor light intensity to achieve the target brightness required to turn on the light-controlled lights.
