With the development of the technology, the demands of users on the lighting lamp are more and more diversified, and the existing linear lighting lamp can only realize the effect change of the whole lighting lamp, can not realize the change of local reduction and expansion of the light emitting area of the linear lighting lamp, and can not realize the deformation of the position of the local light emitting area and the synchronous change along with the gesture position, so that the local lighting and the lighting atmosphere of the light can not be enjoyed. The inventor researches and discovers that the currently adopted reflective infrared sensor technology generally adopts a single sensor, a common LED is adopted as a light source, and an operation instruction is single, so that more interaction effects of gestures and light cannot be presented.
In order to solve the problems, the invention adopts N + X sensors to realize the gesture linkage effect by matching with an addressable LED combination mode, wherein N represents that N sensors are linearly distributed to realize the change of a double-hand gesture command and a single-hand gesture command to synchronize the light area, and X represents 1 left-right direction sensor to realize the switching of the light brightness, color or dynamic mode and the switch state.
As shown in fig. 1, one embodiment of the present invention discloses a system for non-contact direction identification and sliding control of an addressed LED, comprising a sensor assembly 10, an LED lamp assembly 20 and a main controller 30, wherein the main controller 30 is respectively connected with the sensor assembly 10 and the LED lamp assembly 20, specifically, the sensor assembly 10 is connected with an input end of the main controller 30 through an I2C bus, and the LED assembly 20 is connected with an output end of the main controller 30 through an SPI bus. The LED lamp assembly 20 includes a plurality of LED lamps 21 distributed linearly, the sensor assembly 10 includes a plurality of first sensors 11 and a second sensor 12, the plurality of first sensors 11 are distributed linearly, the plurality of first sensors 11 and the second sensor 12 are respectively configured to receive a gesture signal and send the gesture signal to the main controller 30, the main controller 30 is configured to generate a first control command according to the gesture signal of the plurality of first sensors 11, and is configured to generate a lamp turning-on/off command or a second control command according to the gesture signal of the second sensor 12, so as to control the plurality of LED lamps 21 distributed linearly according to the first control command, the lamp turning-on/off command and the second control command.
In the embodiment, the LED lamp assembly 20 includes M LED lamps 21(LED Pixel 1 to LED Pixel M), where each LED lamp 21 is an addressable LED lamp, the LED lamp belongs to a Pixel LED, and single-point control can be realized, and the translation of the light emitting position of the lamp light can be realized by matching with the sensor assembly 10, and is smooth transition, rather than jump transition, which cannot be achieved by a common LED.
The Sensor assembly 10 includes N first sensors 11(Sensor 1-Sensor N) and one second Sensor 12(X Sensor), where M ≧ N such that each first Sensor 11 corresponds to one or more LED lamps 21. The operation principle of the plurality of first sensors 11 and the plurality of second sensors 12 are the same, and all the first sensors 11 and the second sensors 12 adopt infrared sensors, and are distinguished by adopting infrared reflection reception, wherein each first sensor 11 comprises an infrared emission module (IR) and an Infrared Reception Module (IRM), so that two adjacent first sensors 11 are required to be integrated to judge the direction of the gesture movement, and the second sensors 12 comprise an infrared emission module (IR) and two Infrared Reception Modules (IRM), so that the direction of the gesture movement can be judged by a single second sensor 12.

In the effective distance range in front of the sensor, displacement and orientation signals generated by gesture shielding are used as synchronous signals of the light state and the effect, and the interaction effect of light and gestures is formed.
As shown in fig. 2, the input unit adopts N first sensors 11 in linear distribution, collects motion trajectory information of two-gesture shielding and simultaneous back-and-forth translation operation (opposite motion or relative motion) as a synchronization instruction for enlarging or reducing the lighting area, or a synchronization instruction for moving a position sensor hovering between 1 st to N first sensors 11 as an adjusted lighting area position by single-gesture shielding; the input unit also adopts a second sensor 12 (an X-type directional sensor) to acquire a single-gesture shielding left and right translation signal as a synchronous signal for switching the light color or dynamic mode and switching, or the single-gesture shielding hovering on the X-type sensor takes the hovering duration as a total brightness change signal. Wherein the N first sensors 11 and the second sensor 12 are associated with each other, the state of the switch switching signal of the second sensor 12 is a precondition for the operation of the N first sensors 11, and the N first sensors 11 can control the LED lamp assembly only when the switch of the second sensor 12 switches the LED lamp assembly to the on state.

S2: the main controller 30 generates a light switching instruction and controls the LED light assembly 20 to turn on or off according to the light switching instruction, and then performs step S3;
s3: the main controller 30 judges whether the LED lamp assembly 20 is in the on state, and if so, performs steps S4 and S6 simultaneously, and if not, returns to step S1;
s4: the main controller 30 monitors whether gesture signals of a plurality of first sensors 11 are received, and if so, performs step S5, and if not, returns to step S1;
in this step, the main controller 30 starts to sequentially query the feedback information of the 1 st to nth first sensors in a round-robin manner in the light-on state, so as to monitor whether the gesture signals of the plurality of first sensors 11 are received.
S5: the main controller 30 determines whether the received gesture signals of the plurality of first sensors 11 are valid, and if yes, generates a first control command and controls the LED lamp assembly 20 according to the first control command, and if not, returns to step S1;
specifically, step S5 includes:
s51: collecting first gesture information, judging whether the duration of the collected first gesture information is greater than or equal to a first preset time T1, if so, judging the first gesture information to be a valid signal, saving the current position of the first gesture information as the starting point of the first gesture information, and executing the step S52, otherwise, returning to the step S1;
in this step, whether the first gesture information is a valid signal is determined by determining whether the duration of the first gesture information is greater than or equal to a first preset time T1, so as to prevent misoperation.
S52: monitoring whether a second gesture signal is acquired within a second preset time T2 after the first preset time T1, if so, executing the step S53, otherwise, executing the step S57;
s53: judging whether the duration of the acquired second gesture information is greater than or equal to a third preset time T3, if so, judging the second gesture information to be an effective signal, saving the current position of the second gesture information as the starting point of the second gesture information, and then executing the step S54, otherwise, executing the step S57;
the third preset time T3 in this step may be the same as the first preset time T1, and it is determined whether the second gesture information is a valid signal by determining whether the duration of the second gesture information is greater than or equal to the third preset time T3, so as to prevent misoperation.
S54: judging the motion tracks of the first gesture information and the second gesture information, if the first gesture information and the second gesture information are relative motion or opposite motion, judging the first gesture information as an effective signal and executing the step S55, and if the first gesture information and the second gesture information are equidirectional motion, judging the first gesture information and the second gesture information as an ineffective signal and returning to the step S51;
in this step, when the motion trajectories of the first gesture information and the second gesture information are determined, if the motion trajectories are a static and a dynamic relative motion (approaching motion) or an opposite motion (departing motion), or two simultaneous dynamic relative motions (approaching motion) or an opposite motion (departing motion), the determination is made as an active signal and step S55 is performed, and if the motion trajectories are simultaneous dynamic equidirectional motions, the determination is made as an inactive signal and the step S51 is returned to;

specifically, the conversion range of the light emitting region corresponding to the conversion range command of the light emitting regions of the plurality of linearly distributed LED lamps is generated in proportion to the absolute value of the difference between the first moving distance and the second moving distance, that is, the larger the absolute value of the difference between the first moving distance and the second moving distance is, the larger the conversion range of the light emitting region is, and the smaller the absolute value of the difference between the first moving distance and the second moving distance is, the smaller the conversion range of the light emitting region is. When the first gesture information and the second gesture information are in relative motion, the conversion range of the corresponding light-emitting area is in reduction conversion, and when the first gesture information and the second gesture information are in opposite motion, the conversion range of the corresponding light-emitting area is in expansion conversion.

Taking the first gesture information (left hand gesture) moving 2 units to the right, the second gesture information (right hand gesture) moving 4 units to the left as an example, that is, the final landing point of the first gesture information is on the left side of the starting point, the first moving distance may be a positive value, that is, 2 units, the final landing point of the second moving distance is on the right side of the starting point, the second moving distance may be a negative value, that is, 4 units, the difference between the first moving distance and the second moving distance is calculated as the second moving distance, that is, the first moving distance is-6 units, and since the first gesture information and the second gesture information are relative motions, the reduction range command of the light emitting region should be generated correspondingly, and the reduction range command of the light emitting region corresponding to the moving distance of 6 units is generated correspondingly.
