[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Smart home is a new concept brought by new Internet technologies such as big data and the Internet of Things. Through smart home, people's daily life can become more intelligent and comfortable. The lighting system is the most important and basic part of all homes, so many corresponding products and technologies have been born. Since LED is the main technology in the current lighting system, a large number of smart lighting related technology products based on LED lamps have been born. However, the intelligent operation of current LED lamps requires corresponding mode settings through the central control panel for drive control. Due to the fixed mode, the drive control of this method may not meet the indoor lighting needs and the degree of intelligence is low. For this reason, the present invention provides an LED driving method, and the technical solution is as follows:

[0056] refer to Figure 1 As shown, all LED lamps in the house are obtained, and corresponding lighting information and driving information are obtained according to all the LED lamps;

[0057] Establishing an LED dynamic driving curve of the lighting information and the driving information, and determining a driving range of a corresponding LED lamp according to the LED dynamic driving curve;

[0058] Acquire house information and corresponding positions of all the LED lamps, determine a first current lighting setting according to the positions and the LED dynamic drive curve; adjust the first current lighting setting according to the lighting conditions of the positions and in combination with the LED dynamic drive curve to generate a second current lighting setting;

[0059] All the LED lamps are driven according to the second current lighting setting and the LED dynamic driving curve; house usage characteristic information corresponding to the LED lamps is obtained; the second current lighting setting is adjusted again according to the house usage characteristic information and the LED dynamic driving curve to generate a third current lighting setting;

[0062] The method uses the characteristics of the LED lamps installed in each room. Since the lighting conditions and input current requirements of each LED are different, in order to facilitate intelligent adjustment, the driving information of each LED is obtained, that is, the input current and the corresponding lighting radius are generated to generate respective two-dimensional coordinate systems; and the safety range of each LED lamp is determined through nonlinear regression and safe driving current, and the LED dynamic driving curve is generated; the method can determine the safe driving range for different LED lamps, and at the same time, it can also take into account the possible differences between different batches of the same product, and can perform intelligent adaptive data adjustment of each lamp, perform intelligent driving input, and improve the intelligence level of the LED lamp lighting system;

[0063] Based on the LED dynamic driving curve, the LED dynamic driving curve is adjusted according to the temperature conditions of each room. Since the LED itself is affected by temperature, and the indoor temperature, season and air conditioning factors will cause the lighting brightness of the LED lamp itself to change, the LED dynamic driving curve is further adjusted by obtaining temperature data, which can effectively improve the intelligent adjustment of the LED lamp based on the ambient temperature; at the same time, the image recognition algorithm is further combined to identify the usage habits of the residents in different rooms at different times, and the driving of the LED lamp is further adjusted based on the usage habits, so that the light can reach the brightness most suitable for the current use environment; the above method can perform environmental intelligent adaptive driving adjustment of the LED based on the use environment and environmental parameters, thereby improving the environmental intelligence level of the LED lamp;

[0064] Taking into account that the loss of LED lamps will affect lighting, and in real life the life information of LED lamps may be affected by various reasons, the driving input current information of LED lamps is obtained in real time, and the distance between the current input current and light intensity coordinates and the LED dynamic driving curve is calculated. This method can measure whether the current driving current data affects the life of the LED lamp. If it is greater than the safety threshold, the actual life information of the LED lamp is further calculated, and corresponding measures are taken. This method can avoid a series of accidents caused by lighting problems of LED lamps and improve the intelligence of LED lamp lighting systems.

[0065] Embodiment 1

[0066] For specific description, an LED driving method is described in combination with the following embodiments, including:

[0067] Obtain all LED lamps in the house, and obtain corresponding lighting information and driving information based on all LED lamps;

[0068] The lighting information is the lighting radius of the LED lamp. The lighting radius is , is the minimum illumination radius, is the maximum lighting radius; the driving information is the driving input current data of the LED lamp corresponding to the lighting information;

[0069] The lighting radius is obtained based on experimental data combined with expert experience, and the input current data of the LED lamp is adjusted to obtain the illumination value of the experimental measurement target based on the experiment. The target can be moved;

[0070] The threshold of the illumination value is set based on expert experience. When the target movement process reaches the threshold of the illumination value, the distance between the LED lamp and the target is measured and the corresponding illumination radius is recorded. The illumination value is obtained by measuring with an LED illuminance meter.

[0071] Due to the differences in manufacturing processes and design ideas of different LED lamps, the driving input current information and the actual lighting area size are also different. In order to achieve reasonable and automatic driving adjustment of each LED lamp, multiple lighting data and driving input current sizes in different intervals are collected to facilitate subsequent intelligent analysis and improve the intelligent driving level of LED lamp lighting;

[0072] Establish LED dynamic driving curves of lighting information and driving information, and confirm the driving range of corresponding LED lamps according to the LED dynamic driving curves;

[0073] Further, the illumination radius data and input current data of all LED lamps are obtained, and a two-dimensional coordinate system is established according to the multiple illumination radius data and the corresponding input current data of each LED lamp; the input current data is the horizontal coordinate, and the illumination radius data is the vertical coordinate;

[0074] An initial LED curve is obtained by performing nonlinear regression on a plurality of illumination radius data and a plurality of corresponding input current data; a safe driving input current range of the initial LED curve is determined according to a safe driving input current of the LED lamp;

[0075] Corresponding coordinates are established through the lighting radius data and input current data of different LED lamps. Nonlinear regression based on a large amount of coordinate data can obtain the specific driving control range of each lamp. Considering that the collected data is in the range between the maximum and minimum values ​​of the lamp, but for the service life of the LED lamp, it is also necessary to divide a safe range of driving input current to meet the conditions of daily use. The LED dynamic driving curve generated based on the safe driving input current range and the nonlinear regression method can realize the adaptive intelligent adjustment of each LED, improve the driving adjustment range, and can also make more intelligent adjustments according to the curve changes, thereby improving the intelligent driving adjustment level of the LED lighting system.

[0076] The initial LED curve within the safe driving input current range is the LED dynamic driving curve, and the driving range is the safe driving input current range of the initial LED curve;

[0077] Acquire house information and corresponding positions of all LED lamps, determine a first current lighting setting according to the position and the LED dynamic drive curve; adjust the first current lighting setting according to the lighting conditions of the position and the LED dynamic drive curve to generate a second current lighting setting;

[0078] Further, the calculation of the first current lighting setting and the second current lighting setting is:

[0079] ;

[0080] ;

[0081] ;

[0082] in, is the second current lighting setting of the i-th LED lamp, is the illumination weight of the i-th LED lamp, which takes a value of 0 or 1. is the illumination time weight of the i-th LED lamp, is the lighting impact value of the i-th LED lamp, is the first current lighting setting of the i-th LED lamp, and is the minimum driving value and maximum driving value of the LED dynamic driving curve DC of the i-th LED lamp, is the room volume of the location of the i-th LED luminaire, and max represents the maximum value;

[0083] Indicates whether there is light in the room. The value of a room that can be illuminated is 1, such as a bedroom with a window or balcony; the value of a room that cannot be illuminated is 0, such as some warehouses, cloakrooms, etc.

[0084] The lighting of the current room at different times is affected by natural light such as the sun or non-natural light such as street lights. It is mainly used to determine whether the room will be affected at the corresponding time. The value is set to 0 and 1 according to the time; for example, the street light is set to 1 at night and 0 during the day; the sun is set to 1 during the day and 0 at night;

[0085] This corresponds to the illumination data of the room at different times when it is exposed to natural light such as the sun or non-natural light such as street lamps;

[0086] Different rooms are exposed to different amounts of light at different times. For example, a room with windows will be brighter than a room without windows. The room's windows are to the east or west, which will affect the light intensity of the room at different times. The room's location, window orientation, and time will all result in an initial light intensity in the room. In order to avoid excess current loss, the room's light intensity can be calculated based on the LED dynamic drive curve, which can achieve a more intelligent light intensity for the LED, save current intelligently, and improve the intelligent driving level of the LED lighting system under ambient light conditions.

[0087] All LED lamps are driven according to the second current lighting setting and the LED dynamic driving curve; house usage characteristic information of the corresponding LED lamps is obtained; the second current lighting setting is adjusted again according to the house usage characteristic information and the LED dynamic driving curve to generate a third current lighting setting;

[0088] Furthermore, the third current lighting setting obtains the character action characteristics and usage time of the room where the LED lamp is located by combining the image data obtained by the sensor device or the monitoring device with the image recognition model (such as convolutional neural network, yolov5, etc.), and the character action characteristics and usage time are the house usage characteristic information;

[0089] The image recognition model mainly obtains the corresponding image information through the camera installed in the house, transmits the image data to the server through the network for analysis and records the time after the action feature is recognized; when lighting is performed, the LED lamps are adjusted to the lighting range corresponding to the person's behavior according to the lighting settings and LED dynamic drive curve; by identifying the situation of each family, personalized and intelligent corresponding settings can be achieved, and the default settings can also reduce the workload of image data recognition and analysis;

[0090] However, in the specific implementation process, some additional situations may occur in the default lighting settings. For example, multiple people appear in a study room that was originally occupied by one person. Therefore, it is necessary to monitor the behavioral characteristics in the current room and make adjustments based on different situations. Figure 2 As shown, when the action characteristics of the character change, the LED lamp is adjusted to another set lighting range corresponding to the character's behavior according to the LED dynamic driving curve; the action characteristic recognition after the default setting will be monitored once every monitoring time T (for example, but not limited to 3 minutes, 5 minutes, 7 minutes, etc.);

[0091] Obtaining driving influence parameters of each LED lamp at a position, and performing lighting according to the driving influence parameters and the LED dynamic driving curve in combination with the third current lighting setting;

[0092] In the specific use process, each person needs a different light source. For example, a family eating in a room or a person reading at a table requires different LED light intensities. Since different families spend different time and use different rooms, the image recognition algorithm is used to collect the motion characteristics of each family. Based on each characteristic, the corresponding light intensity is adopted, which can improve the user's comfort and further save power loss. This method can be combined with the user's usage scenario for intelligent settings, and improve the intelligent driving level of LED lamps in environmental usage scenarios.

[0093] Furthermore, the average temperature information of the position of each LED lamp is obtained, a temperature change curve is established according to the average temperature information and time, and the LED lighting current adjustment value is calculated by combining the temperature change curve and the LED dynamic drive curve:

[0094] ;

[0095] in, is the LED lighting current adjustment value, Mapping curves for temperature and lighting range, is the average temperature information of the tth day on the temperature change curve of the i-th LED lamp position, and F is based on Calculate the current adjustment function of the driving input current of the LED dynamic driving curve DC within the lighting range;

[0096] Through a large number of experiments, the influence of different temperatures on the illumination range of LED lighting under the same driving input current is obtained; with temperature data as the horizontal axis and the lighting range as the vertical axis, a nonlinear regression method is used to generate a mapping curve between temperature and lighting range under the current driving input current;

[0097] F is based on a large number of experiments with the current drive input current as the benchmark. Under different temperatures, if the lighting range changes, the drive input current is adjusted according to the LED dynamic drive curve, the current lighting range is adjusted to the same lighting range data as before, and the adjustment value of the drive input current is recorded. Under the same drive input current data, the current adjustment function is generated through the data statistics and nonlinear regression method of a large number of current adjustment values.

[0098] LED lamps are affected by different temperatures. In actual use, seasonal temperature and air conditioning will cause different temperatures in different rooms. In addition, the temperature and heat dissipation of the LED itself will cause the LED lighting range to increase or decrease. In order to ensure the comfort of users' LED lamps and prevent the lights from being too bright or too dark, the average temperature data of the rooms where each LED is located in different seasons and at different times is obtained to make more detailed adjustments to the dynamic drive curves of each LED, so as to achieve intelligent drive input when the LED lamps meet the lighting conditions. This ensures the normal use of LED lamps, saves electricity and increases the use time of LED lamps. Environmental factors are taken into consideration to improve the intelligent drive level of LED lamps under different environmental influences.

[0099] Monitor the driving data information of the LED lamp; calculate the abnormal driving information of the LED lamp according to the third current lighting setting, the driving data information and the LED dynamic driving curve; evaluate the life information of the LED lamp according to the abnormal driving information, and take corresponding measures according to the life information;

[0100] Furthermore, the driving data information is the actual input current data of the LED lamp, and an abnormal monitoring point is generated according to the actual input current data and the lighting radius data of the third current lighting setting; and the abnormal distance between the abnormal monitoring point and the LED dynamic driving curve is calculated. , and compare the safety monitoring interval Conduct assessments;

[0101] like It is judged as abnormal, and the corresponding life information of the LED lamp is obtained according to the actual input current data; D is the shortest Euclidean distance between the current abnormal monitoring point and the LED dynamic drive curve; the safety monitoring interval The safe distance range is obtained based on a large amount of data combined with expert experience; The minimum value is 0; Reference for value Figure 3 As shown, Figure 3 is the LED dynamic driving curve obtained through simulation data, Figure 3 The upper and lower curves are The value of

[0102] During the use of household LED lamps, the LED lamps may input wrong driving current data due to system call errors, power outages or driving power errors. These current data are likely to cause the LED lamps to lose, resulting in the LED brightness failing to reach normal brightness. Therefore, the actual input current data is obtained and combined with the target light intensity to generate coordinates, and it is determined whether the distance of the coordinates from the LED dynamic driving curve exceeds the safety threshold. If it exceeds the threshold, the life information of the LED is further calculated and corresponding measures are taken. This method can prevent the brightness from failing to reach normal brightness due to the loss of the lamps during the intelligent driving and regulation process of the LED lamps, causing some accidents. For example, the brightness of the lamps is not enough at night, causing accidents for the elderly or children because they cannot see clearly, so as to improve the intelligent driving level of LED lamps in hazard monitoring.

[0103] If the life information is less than the life threshold, the user is reminded to replace it; if the life information is greater than the life threshold, the LED lamp is marked and the life information is recorded; the life information and life threshold are obtained based on statistical calculations of a large amount of experimental data.
