As shown in Figure 4, the control method of intelligent Worn type light fixture of the present invention, comprises the following steps:
The wearing position of S1, sensing light fixture, generates position jump signal data;
S2, whether be in intelligent control mode according to position jump signal data setting light fixture;
S3, when lamp settings is in intelligent control mode, the motion state data of sensing light fixture, and according to motion state data, generate the control command controlling light fixture corresponding function;
S4, according to control command, drive light fixture perform corresponding function.
In some embodiments of the invention, in step sl, by the infrared signal of pyroelectric infrared sensor sensing light fixture periphery, and position jump signal data are generated according to infrared signal.When light fixture be worn on user with it time, infrared signal that pyroelectric infrared sensor senses can become suddenly large; When light fixture is taken with it from user, the infrared signal that pyroelectric infrared sensor senses can diminish suddenly.In step s 2, become suddenly large setting light fixture according to infrared signal and be in intelligent control mode.
In step s 2, step is comprised:
S2-1: the first threshold of intelligent control mode is opened in setting;
S2-2: the Second Threshold of intelligent control mode is closed in setting; Wherein, first threshold is greater than described Second Threshold;
S2-3: in setting-up time section, continuous acquisition position jump signal data, and after averaging, compare with first threshold and Second Threshold; When the mean value of position jump signal data is greater than first threshold, setting light fixture is in intelligent control mode; When the mean value of position jump signal data is less than Second Threshold, setting light fixture exits intelligent control mode.This setting operation can avoid the frequent of intelligent mode to open and close by mistake.
Such as, A is set to the mean value of the position jump signal data of continuous acquisition in 1 second, B is set to first threshold, and C is set to Second Threshold, wherein B > C; As A > B, setting light fixture is in intelligent control mode; As A < C, setting light fixture exits intelligent control mode, enters ordinary control mode.
Composition graphs 1, in this step S2, by setting first threshold and Second Threshold in processing unit 10, position jump signal data compare with this first threshold and Second Threshold in processing unit 10, judge whether to open and close intelligent control mode by comparative result.In step s3, when intelligent control mode starts, action sensing device 30 works, the motion state data of sensing light fixture.
In step s3, the motion state data of light fixture are sensed by one or more in acceleration transducer, gyroscope, magnetometer; The motion state data of sensing comprise angular speed, linear acceleration etc.
This step S3 can comprise the following steps:
S3-1: setup control instruction threshold value;
S3-2: by motion state data compared with control command threshold value, when motion state data are greater than control command threshold value, generates corresponding control command.
The motion state data received and this control command threshold value, in this step S3, by setup control instruction threshold value in processing unit 10, are compared by composition graphs 1, generate the control command controlling light fixture corresponding function according to comparative result.In step s 4 which, light source assembly 40 performs the functions such as light, extinguishing, change light according to control command.
Further, further comprising the steps of in step S3:
S3-3: by setting low-frequency noise threshold value and high-frequency noise threshold value, the low-frequency noise in motion state data and high-frequency noise are filtered.
At light fixture with user static or when slowly moving, the motion state data sensed belong to low-frequency noise, walk about with user at light fixture, operation shake time, the motion state data sensed belong to high-frequency noise, motion state data under both of these case all belong to interference noise, control not to light fixture, therefore should filtering, to avoid causing misoperation to light fixture.This step S3-3 can carry out before step S3-2, was first filtered the low-frequency noise in motion state data and high-frequency noise respectively by high pass filter and low pass filter, then by the motion state data after filtration compared with control command threshold value.
As selection, high pass filter can select cut-off frequency to be 2Hz filter, and low pass filter can select cut-off frequency to be the filter of 20Hz.
Such as, in step s3, the data (X, Y, Z) of three axis when user's head is shaken the head or nods are recorded by 3-axis acceleration sensor or three-axis gyroscope; Because the installation site of action sensing device 30 in light fixture is controlled, and the usual method of light fixture is also fixing, and therefore suppose X to be considered as direction (double swerve) data of shaking the head, Y is considered as direction (teetertottering) data of nodding; M is set to the control command threshold value to inductive switch (light or extinguishing) control command, N is set to the control command threshold value to strain photocontrol instruction, as X > M, generate switching control instruction, generate as Y > N and become photocontrol instruction.
When being recorded the data (X of three axis when user's head is shaken the head or nods by 3-axis acceleration sensor or three-axis gyroscope, Y, Z) containing high-frequency noise and low-frequency noise in, in order to accuracy of judgement, to the motion state data (X gathered, Y, Z) carry out low-pass filtering and high-pass filtering process obtain effective exercise status data between low-frequency noise threshold value and high-frequency noise threshold value (X ', Y ', Z '), as X ' > M, generate switching control instruction, generate as Y ' > N and become photocontrol instruction.
In step s3, further comprising the steps of:
S3-4: setting window interval time, in interval time of this setting in window, is consecutively detected the motion state data being greater than control command threshold value and is considered as invalid, do not generate control command.
Under special circumstances as user bumpy sections walking or by bike time, the motion state data sensed are between low-frequency noise threshold value and high-frequency noise threshold value, and be greater than control command threshold value, equally can to lamp operation misoperation, therefore, by the setting of window interval time, by the interval time of setting in window, the control command threshold value motion state data that are greater than be consecutively detected are considered as invalid, do not generate control command.
Such as, in particular cases above-mentioned, the motion state data sensed are interference signal, and the characteristic generally can not significantly rocked continuously when controlling light fixture according to user, the interval time that double light fixture operate condition data Rule of judgment is set up is set to T, window interval time of setting is set to W, use time window algorithm, as T<W, it is invalid the motion state data be consecutively detected to be considered as, and does not generate control command.
Due to custom and the operational environment difference to some extent of the user of different crowd (as Different age group), control command threshold value in this control method, low-frequency noise threshold value, high-frequency noise threshold value and interval time window requirement also difference to some extent, in order to reach each crowd user can this light fixture easy to use and to greatest extent reduce misoperation control object, this control method also includes intelligent learning pattern, comprises the following steps:
S4-1: preset many group acquiescence control command threshold values, acquiescence low-frequency noise threshold value, acquiescence high-frequency noise threshold value, default interval time window according to use crowd;
S4-2: the motion state data sensed that use first according to user select one group of immediate acquiescence control command threshold value, acquiescence low-frequency noise threshold value, acquiescence high-frequency noise threshold value, default interval time window;
S4-3: according to motion state Data Update and/or optimization acquiescence control command threshold value, acquiescence low-frequency noise threshold value, acquiescence high-frequency noise threshold value, the default interval time window of sensing.
Wherein, step S4-1 can carry out before step S1, thus is preset in organizing acquiescence control command threshold value, acquiescence low-frequency noise threshold value, acquiescence high-frequency noise threshold value and default interval time window in light fixture more.After the first use, from above-mentioned many group default data, selected one group is immediately carried out memory storage to user, so as this user upper once use time directly select these selected data to compare judgement.
In step s 4 which, as selection, multiple default data can carry out arranging and storing according to the crowd of 10-20 age bracket, 20-30 age bracket, 30-40 age bracket, 40-50 age bracket, 50-60 age bracket and more than 60 age brackets respectively.After using acquiescence low-frequency noise threshold value and acquiescence high-frequency noise threshold value to filter motion state data during the use first of user, and acquiescence control command threshold value compares.Thus select immediate acquiescence control command threshold value, acquiescence low-frequency noise threshold value and acquiescence high-frequency noise threshold value.In user repeatedly use procedure, the regularity according to the many groups motion state data obtained optimizes each default threshold above-mentioned.
F1 is set to high-frequency noise threshold value, f2 is set to low-frequency noise threshold value, and M, N are set to control command threshold value, and W is window interval time; In the process that user uses, according to the parameters in the use habit of operate condition data analysis user gathered and operational environment dynamic micro-adjustments default set (f1, f2, M, N), easily manipulate light fixture accurately so that user is follow-up and reduces misoperation to greatest extent.
The update rule of M parameter:
As X ' >M, M=M+ [(X '-M)/2];
As X ' <M and (M-X ') <M ' time, M=M-[(M-X ')/2];
Certainly, M will be more than or equal to M ' all the time, and M ' is the minimum value of acquiescence control command threshold value.
And M will be less than or equal to M all the time ", M " is the maximum of acquiescence control command threshold value.
The update rule of N parameter:
As Y ' >N, N=N+ [(Y '-N)/2];
As Y ' <N and (N-Y ') <N ' time, N=N-[(N-Y ')/2];
Certainly, N will be more than or equal to N ' all the time, and N ' is the minimum value of acquiescence control command threshold value.
And N will be less than or equal to N all the time ", N " is the maximum of acquiescence control command threshold value.
The update rule of f1, f2: when having determined light fixture control action, calculates centre frequency F amendment f1, f2 of temporary raw motion data threshold value f1, f2, makes f1=F-7Hz, f2=F+7Hz.
From the above, the present invention is by sensing lamp position to start the intelligent control mode of light fixture, under intelligent control mode working condition, sense the motion state of light fixture, perform by motion state data the corresponding function that corresponding control command controls light fixture, realize the action Based Intelligent Control of light fixture.
