Its The position sensing device 20 is configured to sense the position of the entire luminaire, and send the sensed position abrupt signal data to the processing device 10; the motion sensing device 30 is configured to sense the motion state of the entire luminaire, and sense The measured motion state data is sent to the processing device 10; the processing device 10 opens and closes the motion sensing device 30 according to the received position abrupt signal data, and generates a control light source component according to the motion state data sensed by the motion sensing device 30. 40 corresponding function control commands, and control of the light source assembly 40 to perform corresponding functions.

In some embodiments of the present invention, the position sensing device 20 may include a pyroelectric infrared sensor for sensing an infrared signal at the periphery of the lamp, and generating position abrupt signal data according to the infrared signal, and outputting To the processing device 10. When the luminaire is worn on the user, the infrared signal sensed by the pyroelectric infrared sensor suddenly becomes large; when the luminaire is removed from the user, the infrared signal sensed by the pyroelectric infrared sensor suddenly becomes smaller. In order to determine whether the luminaire is worn on the user. By determining that the lamp is worn on the user and then actuating the motion sensing device 30 to sense the operating state data of the lamp, it is possible to avoid unnecessary power waste caused by the sensing operation of the motion sensing device 30 when the lamp is not worn.

In some embodiments of the invention, the motion sensing device 30 may include one or more of an acceleration sensor, a gyroscope, and a geomagnetic instrument for sensing motion state data of the luminaire. The motion state data of the luminaire includes data such as angular velocity and linear acceleration.

The processing device 10 can employ a single chip microcomputer (MCU). As shown in FIG. 2, the processing device 10 can include a position signal sampling module 11, a control module 12, an action signal acquisition module 13, an action signal processing module 14, and an invocation module 15. The position signal sampling module 11 is configured with a first threshold and a second threshold, wherein the first threshold is greater than the second threshold; the position signal sampling module 11 is configured to collect the position mutation signal data sent by the position sensing device 20, and position the position The abrupt signal data is compared to a first threshold and a second threshold. Further, the position signal sampling module 11 can continuously collect for a predetermined period of time. The position mutation signal data is taken, and the average value of the position mutation signal data is compared with the first threshold and the second threshold. The control module 12 is connected to the position signal sampling module 11. When the position abrupt signal data threshold is greater than the first threshold, the control module 12 activates the motion sensing device 30, thereby turning on the intelligent control mode of the lamp, and the motion sensing device 30 works. The motion state of the light fixture is measured; the control module 12 turns off the motion sensing device 30 when the positional abrupt signal data threshold is less than the second threshold. The motion signal sampling module 13 is configured to collect the motion state data sensed by the motion sensing device 30. The motion signal processing module 14 is connected between the motion signal sampling module and the 13 control module 12 for filtering the motion state outside the preset threshold. The data, and/or motion state data within a preset threshold that occurs continuously within the interval window is considered invalid. The calling module 15 is connected to the control module 12, and calls the corresponding control command in the control module 12 according to the filtered motion state data. The control module 12 drives the light source assembly 40 to perform corresponding functions in accordance with the control commands. The light source assembly 40 performs functions such as lighting, extinction, dimming, and the like according to the control command.

The control module 12 is further configured with a control command threshold, which compares the collected motion state data with a control command threshold, and generates a corresponding control command when the motion state data is greater than the control command threshold.

When the luminaire is worn on the user, the luminaire will move with the user's walking or working, and these movements are interference movements, and the user does not need to control the movement operation of the luminaire. Therefore, in order to avoid interference with the movement, the luminaire is brought to the luminaire. In some embodiments of the present invention, the motion signal processing module 14 includes a high pass filter and/or a low pass filter, the high pass filter and the low pass filter respectively set a low frequency noise threshold and high frequency noise set by themselves. Threshold, filtering out low frequency noise and high frequency noise. When the luminaire moves statically or slowly with the user, the motion sensing device 30 has a continuous motion state data output in the sensing direction, and the output data is regarded as low frequency noise; when the luminaire moves with the user, the operation jitters At the time, the motion sensing device 30 has a continuous motion state in the sensing direction. According to the output, the output data is regarded as high frequency noise. Therefore, as an option, the high-pass filter can be selected with a cutoff frequency of 2 Hz, and the low pass filter can be selected with a cutoff frequency of 20 Hz. The motion signal processing module 14 filters the motion state data having a frequency other than 2-20 Hz through the setting of the high pass filter and the low pass filter.

In addition, in a special case, if the user walks or rides on a bumpy road, the motion sensing data sensed by the motion sensing device 30 is within 2-20 Hz and is greater than the control command threshold, which may also cause an erroneous operation on the luminaire. In order to further filter out the interference noise, the action signal processing module 14 can set an interval time window, which is continuously within a preset threshold within a set interval time window (eg, 300 milliseconds) by the time window algorithm (low frequency The motion state data within the noise threshold and the high frequency noise threshold is considered invalid.

Further, the processing device 10 further includes an action signal learning module, configured to preset a plurality of sets of default control instruction thresholds, a default low frequency noise threshold, a default high frequency noise threshold, a default interval time window according to the usage population, and according to the first use of the user. The sensed motion state data selects a set of closest default control command thresholds, a default low frequency noise threshold, a default high frequency noise threshold, and a default interval window. In subsequent use, processing device 10 may determine subsequent sensed motion state data based on a first selected default control command threshold, a default low frequency noise threshold, a default high frequency noise threshold, and a default interval window. During the use of the user, according to the user's manipulation action (violent, gentle, etc.), the motion sensing device 30 senses that the angular velocity, the linear acceleration, and the like are different. Therefore, the motion signal learning module can also be used according to the use. The multiple-use sensed motion state data optimizes the default control command threshold, the default low-frequency noise threshold, the default high-frequency noise threshold, the default interval window, the default control command threshold, the default low-frequency noise threshold, the default high-frequency noise threshold, The default interval window is optimized to be consistent or consistent with the data obtained by the user.

In some embodiments of the invention, the luminaire is a headlight, and the processing device 10, the position sensing device 20, the motion sensing device 30, and the light source assembly 40 are integrated in a housing. When the lamp is a headlight, the user can control the function of opening and closing, dimming, etc. by simply moving the head, and the hands can be completely released for work. The housing can be set according to different requirements such as light weight, partial voyage, partial waterproof and partial brightness, so as to be suitable for different occasions. The position sensing device 20 faces the user on the housing. The motion sensing device 30 can be a three-axis acceleration sensor that can measure three axial acceleration data when the user's head shakes or nods; the motion sensing device 30 can also be a three-axis gyroscope that can measure the user's head. Three axial angular velocity data when shaking or nodding.

In the practical application of the smart wearable luminaire for the headlight, after the user wears the headlight on the head, the user can control the headlight switch or dim the light by shaking his head or nodding, completely releasing the hands, facilitating the two-hand operation. In order to avoid danger or missed opportunities in an emergency situation due to the failure to handle the headlights.

In other embodiments, the luminaire can also be a luminaire worn on other parts of the user such as the arms, waist, and the like.

In addition, the luminaire further includes a power supply device 60, which is respectively connected to the processing device 10, the position sensing device 20, the motion sensing device 30, and the light source assembly 40, and is a processing device 10, a position sensing device 20, and a motion sensing device 30. And the light source assembly 40 is powered. The power supply unit 60 is also integrated in the housing.

The position sensing device 20 includes a pyroelectric infrared sensor, the pyroelectric infrared sensor includes a probe for collecting an infrared signal, an amplifying circuit and a filter circuit, the amplifying circuit is connected to the probe, and the filter circuit is connected.

Light source assembly 40 includes at least one LED light set; in some embodiments of the present invention, light source assembly 40 can include three LED light sets, each of which includes an LED drive circuit coupled to processing device 10. The power supply device 60 supplies power to the processing device 10, the position sensing device 20, the motion sensing device 30, the light source assembly 40, and the like.

In some embodiments of the invention, the smart wearable luminaire further includes a control assembly 50 coupled to the processing device 10 for manually controlling the corresponding function of the luminaire. The control assembly 50 is disposed on the housing. In the normal mode (non-intelligent mode), the corresponding function of the luminaire can be controlled directly by the control component 50. Alternatively, the control component 50 can include one or more of a button, a rocker, etc., by sending a control signal to the processing device 10 by pressing a button or rocking the joystick, and transmitting the control command to the light source assembly 40 by the processing device 10. Control to perform the appropriate function.

As shown in FIG. 4, the control method of the smart wearable luminaire of the present invention comprises the following steps:

S1, sensing a wearing position of the luminaire, generating a position mutation signal data;

S2, setting whether the luminaire is in an intelligent control mode according to the position mutation signal data;

S3. When the luminaire is set in the intelligent control mode, sensing the motion state data of the luminaire, and generating a control instruction for controlling the corresponding function of the luminaire according to the motion state data;

S4. Drive the lamp to perform the corresponding function according to the control instruction.

In some embodiments of the present invention, in step S1, the infrared signal of the periphery of the lamp is sensed by the pyroelectric infrared sensor, and the positional abrupt signal data is generated based on the infrared signal. When the luminaire is worn on the user, the infrared signal sensed by the pyroelectric infrared sensor suddenly becomes large; when the luminaire is removed from the user, the infrared signal sensed by the pyroelectric infrared sensor suddenly becomes smaller. . In step S2, the luminaire is set to the intelligent control mode according to the sudden increase of the infrared signal.

In step S2, the steps are included:

S2-1: setting a first threshold for turning on the intelligent control mode;

S2-2: setting a second threshold for turning off the intelligent control mode; wherein the first threshold is greater than the second threshold;

S2-3: continuously collecting the position mutation signal data in the set time period, and after comparing the average, comparing with the first threshold and the second threshold; when the average value of the position mutation signal data is greater than the first threshold, setting The luminaire is in the intelligent control mode; when the average value of the position abrupt signal data is less than the second threshold, the luminaire is set to exit the intelligent control mode. This setting operation avoids frequent false opening and closing of the smart mode.

For example, set A to the average value of the positional abrupt signal data continuously acquired within 1 second, B is set to the first threshold, C is set to the second threshold, where B>C; when A>B, the set lamp is intelligent Control mode; when A<C, set the lamp to exit the intelligent control mode and enter the normal control mode.

With reference to FIG. 1, in the step S2, the first threshold and the second threshold are set in the processing device 10, and the position mutation signal data is compared with the first threshold and the second threshold in the processing device 10, and the comparison result is judged. Whether to open and close the intelligent control mode. In step S3, in the case where the intelligent control mode is activated, the motion sensing device 30 operates to sense the motion state data of the luminaire.

In step S3, motion state data of the luminaire is sensed by one or more of an acceleration sensor, a gyroscope, and a geomagnetic instrument; the sensed motion state data includes angular velocity, linear acceleration, and the like.

The step S3 can include the following steps:

S3-1: setting a control command threshold;

S3-2: Comparing the motion state data with the control command threshold, and generating a corresponding control command when the motion state data is greater than the control command threshold.

Referring to FIG. 1, in step S3, the control command threshold is set in the processing device 10, the received motion state data is compared with the control command threshold, and the control light is generated according to the comparison result. Control instructions with corresponding functions. In step S4, the light source assembly 40 performs functions of bright light, extinction, dimming, and the like according to the control command.

Further, the step S3 further includes the following steps:

S3-3: Filter low frequency noise and high frequency noise in the motion state data by setting a low frequency noise threshold and a high frequency noise threshold.

When the luminaire moves statically or slowly with the user, the sensed motion state data belongs to low frequency noise, and the sensed motion state data belongs to high frequency noise when the luminaire moves with the user and the work jitters. The motion state data underneath is interference noise, not the control of the luminaire, so it should be filtered to avoid misoperation of the luminaire. The step S3-3 can be performed before the step S3-2, and the low-frequency noise and the high-frequency noise in the motion state data are respectively filtered by the high-pass filter and the low-pass filter, and then the filtered motion state data and the control are performed. The instruction thresholds are compared.

Alternatively, the high pass filter may use a 2 Hz cutoff filter and the low pass filter may use a 20 Hz cutoff filter.

For example, in step S3, three axial data (X, Y, Z) when the user's head shakes or nods are measured by a three-axis acceleration sensor or a three-axis gyroscope; since the motion sensing device 30 is inside the lamp The installation position is controllable, and the wearing method of the luminaire is also fixed, so it is assumed that X is regarded as the direction of shaking head (swaying left and right) data, Y is regarded as the direction of the nodding direction (swaying up and down); setting M as the corresponding switch (light or Off) The control command threshold of the control command, N is set to the control command threshold corresponding to the dimming control command. When X>M, the switch control command is generated, and when Y>N, the dimming control command is generated.

When the user's head is shaken or nodding by a three-axis accelerometer or a three-axis gyroscope, the three axial data (X, Y, Z) contain high frequency noise and low frequency noise, in order to judge accurately, the collected The motion state data (X, Y, Z) is subjected to low-pass filtering and high-pass filtering to obtain effective motion state data (X', Y', Z') between the low-frequency noise threshold and the high-frequency noise threshold, when X'> M At the time, a switch control command is generated, and when Y'>N, a dimming control command is generated.

In step S3, the following steps are further included:

S3-4: Set the interval time window. During the set interval time window, the motion state data that is continuously detected to be greater than the control command threshold is regarded as invalid, and no control command is generated.

In special cases, if the user walks or rides on a bumpy road, the sensed motion state data is between the low frequency noise threshold and the high frequency noise threshold, and is greater than the control command threshold, which also causes misoperation of the luminaire operation. By setting the interval window, the continuously detected motion state data greater than the control command threshold value in the set interval time window is regarded as invalid, and no control command is generated.

For example, in the above special case, the sensed motion state data is an interference signal, and according to the characteristics that the user generally does not continuously sway when controlling the luminaire, the interval between the two luminaire operation state data determination conditions is established. The time is set to T, the set interval time window is set to W, and the time window algorithm is used. When T < W, the continuously detected motion state data is regarded as invalid, and no control command is generated.

Due to differences in the habits and working environment of users of different populations (such as different age groups), the requirements of the control command threshold, the low frequency noise threshold, the high frequency noise threshold and the interval time window in the control method are also different, in order to achieve Users of all groups can easily use the luminaire and minimize the purpose of malfunction control. The control method also includes an intelligent learning mode, including the following steps:

S4-2: selecting a set of the closest default control instruction threshold, a default low frequency noise threshold, a default high frequency noise threshold, and a default interval time window according to the motion state data sensed by the user for the first time use;

S4-3: Update and/or optimize the default control instruction threshold, the default low frequency noise threshold, the default high frequency noise threshold, and the default interval time window according to the sensed motion state data.

预设在灯具中。使用者在首次使用后，从上述多组默认数据中选定一组最接近的进行记忆存储，以便该使用者在下一次使用时直接选用该选定的数据进行比较判断。Wherein, step S4-1 can be performed before step S1, so that multiple sets of default control instruction thresholds, default low frequency noise thresholds, default high frequency noise thresholds, and default interval time windows are used.

Preset in the fixture. After the first use, the user selects a set of the closest memory storage from the plurality of sets of default data, so that the user directly selects the selected data for comparison judgment on the next use.

The crowd is set up and stored. The first time the user uses the default low frequency noise threshold and the default high frequency noise threshold to filter the motion state data and compare it with the default control command threshold. The nearest default control command threshold, the default low frequency noise threshold, and the default high frequency noise threshold are selected. During the multiple use of the user, each of the above default thresholds is optimized according to the regularity of the obtained plurality of sets of motion state data.

Set f1 as the high frequency noise threshold, f2 as the low frequency noise threshold, M and N as the control command threshold, and W as the interval time window; during the user's use, analyze the user's use based on the collected action state data. Habits and work environment dynamically fine-tune the parameters in the default group (f1, f2, M, N) so that the user can easily and accurately manipulate the fixtures and minimize malfunctions.

Update rules for M parameters:

When X'>M, M=M+[(X'-M)/2];

Of course, M must always be greater than or equal to M', and M' is the minimum value of the default control command threshold.

Moreover, M is always less than or equal to M", and M" is the maximum value of the default control command threshold.

Update rules for N parameters:

When Y'>N, N=N+[(Y'-N)/2];

When Y'<N and (N-Y')<N', N=N-[(N-Y')/2];

Of course, N must always be greater than or equal to N', and N' is the minimum value of the default control command threshold.

Moreover, N is always less than or equal to N", and N" is the maximum value of the default control command threshold.

f1、f2的中心频率F修改f1、f2，使f1＝F-7Hz，f2＝F+7Hz。F1, f2 update rule: when it is judged that there is a luminaire control action, calculate the temporary original action data
