In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
Fig. 1 shows a flow chart of a method of controlling a light strip display of the present invention.
As shown in fig. 1, the invention discloses a method for controlling a display of a lamp strip, which comprises the following steps:
s102, selecting a corresponding control template to start a lamp belt according to a rated brightness value selected by a user;
s104, verifying the display effect of the lamp strip through a photosensitive sensor, and marking the abnormal light emitting module;
s106, adjusting control parameters of the abnormal light emitting module to enable the actual brightness value of the abnormal light emitting module to meet the rated brightness value;
s108, when the control parameters of the abnormal light emitting module cannot be adjusted to enable the actual brightness value of the abnormal light emitting module to be adjusted to the rated brightness value, the control parameters of the abnormal light emitting module are adjusted to be first preset parameters, and the control parameters of other light emitting modules are adjusted to be second preset parameters;
s110, adjusting the power supply voltage of the lamp strip and the control parameters of the abnormal light emitting module based on a preset adjustment factor to enable the actual brightness value of the abnormal light emitting module to meet the rated brightness value;
and S112, adjusting control parameters of other light-emitting modules based on the adjusted lamp band supply voltage, so that the lamp band is displayed with a rated brightness value.
According to the embodiment of the invention, the lamp strip is formed by connecting a plurality of identical light-emitting modules in parallel, and the light-emitting modules at least comprise an adjustable resistor and a lamp bead. The lamp strip is connected with an adjustable power supply, and the power supply voltage of the lamp strip is adjusted through the adjustable power supply. And adjusting the resistance value of the adjustable resistor according to the actual power supply voltage and the lamp bead state of each light-emitting module, so that each light-emitting module of the lamp strip can display according to the rated brightness value. When a user starts the lamp strip, the system selects a corresponding control template in the database according to the rated brightness value selected by the user to start the lamp strip, and the movable photosensitive sensor detects the display effect (brightness value) of each light emitting module or each section of lamp strip on the lamp strip to verify, so as to determine the abnormal light emitting module;
in the process of adjusting the abnormal light-emitting module, preferentially judging whether the lamp beads meet the rated brightness value under the maximum power, if not, judging that the abnormal light-emitting module is in fault, and cutting off the power supply of the abnormal light-emitting module to wait for maintenance; if the brightness value is satisfied, the control parameters of the abnormal light emitting module, namely the resistance value of the adjustable resistor, are adjusted to adjust the power supply voltage and the power supply current of the lamp beads in the abnormal light emitting module, so that the lamp beads in the abnormal light emitting module emit light according to the rated brightness value. If the control parameters of the abnormal light emitting module cannot be adjusted to enable the actual brightness value of the abnormal light emitting module to be adjusted to the rated brightness value, adjusting the power supply voltage of the abnormal light emitting module through an adjustable power supply to adjust the power supply voltage of a lamp strip, and adjusting the resistance value of an adjustable resistor in the abnormal light emitting module according to a preset adjusting factor at the same time, so that the power supply voltage and the power supply current of the lamp bead in the abnormal light emitting module are synchronously adjusted according to a certain ratio. The purpose of setting the first preset parameter and the second preset parameter is to ensure that the actual power of other light emitting modules is greater than the maximum power in the process of adjusting the power supply voltage, so that the lamp beads are damaged. In addition, when the control parameters of other light-emitting modules are adjusted, the light-emitting modules to be adjusted with the same luminous efficiency can be adjusted synchronously according to the adjusted control parameters of the light-emitting modules, so that the adjustment efficiency is improved.
FIG. 2 is a flow chart showing a method for verifying luminous efficiency of a luminous module according to the present invention;
as shown in fig. 2, according to an embodiment of the present invention, further includes:
s202, adjusting the control parameter of each light emitting module to a default parameter;
s204, independently supplying power to each light-emitting module by adjusting the power supply voltage of the lamp strip, so that each light-emitting module works under the rated voltage;
s206, comparing the actual brightness value of each light-emitting module under the rated power supply parameter with the rated brightness value to determine the light-emitting efficiency k of each light-emitting module 1 ；
And S208, recording the luminous efficiency verification time, and periodically verifying and updating the luminous efficiency of each luminous module of the lamp strip based on the preset time interval.
The luminous efficiency k 1 The method comprises the steps of measuring and determining a plurality of influencing factors such as lamp bead types of lamp beads in a light-emitting module, lamp pearl attenuation and the like, respectively setting corresponding influencing weights for each influencing factor, and determining the light-emitting efficiency k of the light-emitting module according to the sum of products of all influencing factors and the corresponding influencing weights 1 . With the use of the lamp strip, the luminous efficiency of the lamp strip luminous module is reduced, and the actual brightness value of the lamp strip is lower than the rated brightness value. Therefore, the luminous efficiency of the lamp strip luminous module needs to be verified and updated regularly, and the preset time interval can be set according to the date, for example, the detection is carried out according to the 7-day interval; the lamp strip can also be set according to the use time length, for example, the lamp strip is detected after the accumulated time length reaches 50 hours. By adjusting the power supply voltage of the lamp strip, each light-emitting module is independently powered, so that the power supply voltage and the power supply current of each light-emitting module are rated values in the verification process, and the influence of the power supply voltage and the power supply current fluctuation on the verification result is avoided.Wherein the default parameters are set by the system.
According to an embodiment of the present invention, further comprising:
the control template comprises a lamp strip power supply voltage and control parameters of each light emitting module;
acquiring the last use time of the corresponding control template;
acquiring the last luminous efficiency verification time of the lamp strip;
judging whether the last time of the corresponding control template is longer than the last time of the luminous efficiency verification of the lamp strip or not;
if yes, starting the lamp belt through the corresponding control template;
if not, starting the lamp belt through a control template when the lamp belt is started last time.
After each start of the lamp strip, a control template is generated according to the rated brightness value selected by the user, the adjusted lamp strip power supply voltage and the control parameters of each light emitting module, and the control template is stored in a database. When the lamp strip is started, the system searches in the database preferentially according to the rated brightness value selected by the user, the last time the lamp strip luminous efficiency verification time and the current time are taken as selection intervals, and a control template with the same rated brightness value in the current time period is selected to adjust the power supply voltage of the lamp strip to be started and the starting parameters of the luminous module. In addition, if the luminous efficiency of the lamp strip luminous module is not changed in the last luminous efficiency verification time, the selection interval can be properly prolonged, and the previous n times of lamp strip luminous efficiency verification time and the current time are taken as the selection interval. In addition, if the control template is selected to start the lamp strip when the lamp strip is started last time, because the luminous efficiency of each luminous module of the lamp strip is determined, the actual brightness value of part of the luminous modules of the lamp strip can be ensured to meet the rated brightness value, and only the control parameters of part of the luminous modules of which the actual brightness value does not meet the rated brightness value need to be verified and adjusted subsequently, so that the starting speed of the lamp strip is improved.
Fig. 3 is a flowchart showing a method for judging an abnormal light emitting module according to the present invention.
As shown in fig. 3, according to an embodiment of the present invention, the verification of the display effect of the light strip by the photosensitive sensor, marking the abnormal light emitting module, includes:
s302, sequentially obtaining the actual brightness value of each light-emitting module through a photosensitive sensor to obtain a first brightness value of each light-emitting module;
s304, comparing the first brightness value of each light-emitting module with a rated brightness value respectively to obtain a first brightness difference value of each light-emitting module;
s306, marking the light emitting module with the first brightness difference value larger than a first preset threshold value as an abnormal light emitting module.
It should be noted that, because the voltage drop exists in the lamp strip, when the lamp strip is longer, the brightness value of the tail end of the lamp strip may be lower than the rated brightness value, which causes brightness difference and affects the splicing effect of the lamp strip. The slide rail can be arranged above the lamp belt or at other positions, the light intensity value of each light-emitting module of the lamp belt can be sequentially detected through the slide rail control photosensitive sensor, and the lamp belt can be detected through intelligent equipment such as an unmanned aerial vehicle, an intelligent robot and the like carrying the photosensitive sensor. Under the condition that the difference of the brightness values is smaller, the human eyes cannot intuitively feel the difference of the brightness, so that through abnormality detection on each light-emitting module based on the difference of the brightness values, the first difference of the brightness values is the absolute value of the difference of the first brightness value and the rated brightness value, and when the first difference of the brightness values is smaller than or equal to a first preset threshold value, the default light-emitting module is a normal light-emitting module, and no light-emitting abnormality exists. When the first brightness difference value is larger than a first preset threshold value, the human eye can obviously detect that the brightness difference exists, namely the light emitting module has abnormal light emission, and the abnormal light emitting module is the abnormal light emitting module. The first preset threshold is set by a person skilled in the art according to actual requirements.
According to an embodiment of the present invention, the adjusting the control parameter of the abnormal light emitting module to enable the actual brightness value of the abnormal light emitting module to meet the rated brightness value includes:
analyzing according to the luminous efficiency of the abnormal luminous module, and judging whether the maximum brightness value of the abnormal luminous module in the maximum power state meets the rated brightness value;
if not, closing a power supply port of the abnormal light emitting module;
and if the brightness value is satisfied, adjusting the control parameters of the abnormal light emitting module, and adjusting the actual brightness value of the abnormal light emitting module to the rated brightness value.
The maximum power is calculated from the maximum voltage and the maximum current in the lamp parameters of the lamp beads in the maximum power luminous module, and the maximum brightness value of the abnormal luminous module in the maximum power state is calculated by combining the luminous efficiency of the luminous module, wherein the maximum brightness value=ηxk 1 X maximum voltage x maximum current, η is the light energy conversion coefficient, and the light energy conversion system is determined by a table look-up method. And (3) compiling an energy table by collecting display brightness values of the lamp beads under different powers, determining rated brightness values of the lamp beads according to known power supply power, and determining a final actual brightness value by combining luminous efficiency. If the maximum brightness value is larger than the rated brightness value, the brightness of the lamp beads can be adjusted in a mode of adjusting the power supply voltage and the power supply current, so that the brightness value of the light-emitting module meets the rated brightness value. Otherwise, the abnormal light emitting module cannot meet the brightness value requirement required by the user, and the damaged condition exists, so that the damaged part of the lamp strip is required to be maintained or replaced. The maximum voltage and maximum current of the lamp bead are the maximum power supply voltage and maximum power supply current of the lamp bead in a normal use state.
According to an embodiment of the present invention, the adjusting the control parameter of the abnormal light emitting module to a first preset parameter and the control parameters of other light emitting modules to a second preset parameter includes:
adjusting control parameters of the abnormal light emitting module based on a first preset parameter to enable the lamp beads in the abnormal light emitting module to supply power according to rated current;
and adjusting control parameters of other light-emitting modules based on the second preset parameters to enable the actual power supply current of the other light-emitting modules to be smaller than the rated current.
It should be noted that, the power supply voltage of the lamp strip is adjusted according to the actual brightness value of the abnormal light emitting module, in order to avoid increasing the power supply voltage to increase the power supply voltage and the power supply current of other light emitting modules, the actual power is larger than the maximum power to damage the lamp beads of other light emitting modules, the control parameters of each light emitting module are adjusted before the power supply voltage is adjusted, the control parameters of other light emitting modules are adjusted to be the second preset parameters, the resistance value of the adjustable resistor in the light emitting module is increased, and the actual power of the lamp beads in the light emitting module is ensured to be smaller than the maximum power in the process of adjusting the power supply voltage of the lamp strip. Meanwhile, the control parameters of the current abnormal light emitting module are adjusted to be first preset parameters, so that the situation that the abnormal light emitting module is adjusted by adjusting the resistance value of the adjustable resistor in the light emitting module to adjust the power supply parameters of the lamp beads when the abnormal light emitting module is subjected to pressure drop again in the adjusting process of other light emitting modules is avoided after the actual brightness value of the abnormal light emitting module is adjusted to be the rated brightness value, and the situation that the abnormal light emitting module is adjusted by adjusting the power supply voltage of the lamp belt is avoided.
The first preset parameter and the second preset parameter are set according to actual requirements by a person skilled in the art, and the resistance value of the adjustable resistor in the first preset parameter is smaller than that of the adjustable resistor in the second preset parameter.
According to an embodiment of the present invention, the adjusting the lamp band supply voltage and the control parameter of the abnormal light emitting module based on the preset adjustment factor to enable the actual brightness value of the abnormal light emitting module to meet the rated brightness value includes:
adjusting the power supply voltage of the lamp strip, and adjusting the resistance value of the adjustable resistor in the abnormal light emitting module according to the adjusted power supply voltage of the lamp strip and a preset adjusting factor;
when the actual brightness value of the abnormal light emitting module is equal to the rated brightness value, finishing the control parameter adjustment of the abnormal light emitting module;
the adjusting method of the resistance value of the adjustable resistor in the abnormal light emitting module is expressed as follows by a formula:
；
wherein lambda is a preset adjustment factor, U Real world For the actual supply voltage, U Forehead (forehead) For the foreheadConstant supply voltage, I Forehead (forehead) For rated supply current, R Resistance resistor Is the actual resistance value, R of the adjustable resistor Lamp with light-emitting device Is the resistance value of the lamp beads in the light-emitting module.
When the power supply voltage of the lamp strip is adjusted, the control parameters of the abnormal light emitting module are adjusted at the same time, and the resistance value of the adjustable resistor in the abnormal light emitting module is adjusted according to the actual power supply voltage, so that the power supply voltage adjustment coefficient and the power supply current adjustment coefficient of the abnormal light emitting module are adjusted according to a certain ratio, and the relation between the power supply voltage adjustment coefficient and the power supply current adjustment coefficient is expressed as follows by a formula:
；
wherein K is 1 For adjusting the coefficient, K, of the supply voltage 2 Adjusting the coefficient, k for the supply current 2 As the pressure drop coefficient, the pressure drop coefficient k 2 The determination is performed by a look-up table method. The system generates a voltage drop coefficient table by collecting voltage drop coefficients of different lamp bands with different types under different power supply voltages and power supply currents.
According to an embodiment of the present invention, the adjusting the control parameters of other light emitting modules based on the adjusted power supply voltage of the lamp strip to display the lamp strip with the rated brightness value includes:
marking all the light-emitting modules of the lamp strip as light-emitting modules to be adjusted, and adjusting control parameters of each light-emitting module to be adjusted in turn according to a power supply sequence;
the actual brightness value of the light-emitting module to be adjusted is adjusted to a rated brightness value, and the control parameters of the light-emitting module to be adjusted are extracted to obtain third preset parameters;
adjusting control parameters of other light-emitting modules to be adjusted, which have the same light-emitting efficiency as the light-emitting modules to be adjusted, based on the third preset parameters, and marking the adjusted other light-emitting modules to be adjusted as light-emitting modules to be verified;
when the next light-emitting module to be adjusted is the light-emitting module to be verified, calculating a second brightness difference value between the actual brightness value and the rated brightness value of the light-emitting module to be verified;
when the second brightness difference value is smaller than a second preset threshold value, skipping adjustment;
otherwise, continuing to adjust, and updating the control parameters of other to-be-verified light-emitting modules with the same light-emitting efficiency according to the adjusted control parameters.
It should be noted that, in order to avoid the influence of voltage drop, the brightness value of the light emitting module is abnormal again, each light emitting module to be adjusted is adjusted in turn according to the power supply sequence, that is, the light emitting module closest to the power supply device is adjusted preferentially. The adjusted parameters of the normal light-emitting module are adjusted by the adjusted lamp band power supply voltage, so that the actual brightness value of the normal light-emitting module reaches the rated brightness value, the light-emitting module to be adjusted with the same luminous efficiency is adjusted based on the adjusted parameters of the normal light-emitting module, and the adjusted brightness value of the light-emitting module to be adjusted only needs to be verified later, so that the adjustment efficiency is improved. The second brightness difference value is the absolute value of the difference value between the actual brightness value and the rated brightness value of the light-emitting module to be verified, and when the second brightness difference value is smaller than a preset threshold value, the actual brightness value of the light-emitting module to be verified meets the use requirement without being adjusted again; otherwise, if the voltage drop and other conditions affect that the actual brightness value of the light-emitting module to be verified does not meet the use requirement, the adjustment needs to be continued on the basis of the third preset parameter, so that the actual brightness value of the light-emitting module to be verified reaches the rated brightness value, the third preset parameter is updated according to the adjusted adjustment parameter, and the light-emitting module to be verified, which is not verified and has the same luminous efficiency, is adjusted according to the updated third preset parameter.
