As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The LED display system of each embodiment of the application, through additionally configuring the power supply battery, the power supply battery provides higher power supply at the peak power consumption stage, and the power supply accessed from the outside only needs to be distributed with reference to the average power consumption, so that the power requirement of the LED display screen on the power supply of the external power supply can be reduced.
The LED display system according to the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a schematic structural diagram of an LED display system 10 according to an embodiment of the present disclosure is exemplarily shown, where the LED display system 10 includes a display screen body 110, a control system 120, a distribution box 130 and a power supply battery 140, and the control system 120 is connected to the display screen body 110 and is used for controlling the display of the display screen body 110; the distribution box 130 is electrically connected to the control system 120 and the display screen body 110, and is used for supplying power to the control system 120 and the display screen body 110; the power supply battery 140 is connected to the display screen body 110 and is in signal connection with the control system 120, and when the power consumption of the display screen body 110 exceeds a first preset value, the control system 120 cuts off the power supply of the distribution box 130 to the display screen body 110 and controls the power supply battery 140 to supply power to the display screen body 110.
By configuring the power supply battery 140, when the power consumption of the display screen body 110 exceeds a first preset value, the power supply side of the display screen body 110 is changed from the distribution box 130 to the power supply battery 140, and the power supply battery 140 supplies power in a peak stage. When the power consumption of the display screen body 110 is low, the external power source supplies power with low power through the distribution box 130, and the power supply power at this time only needs to refer to the average power consumption of the display screen body 110, for example, may be slightly larger than the average power consumption of the display screen body 110. When the power consumption exceeds the first preset value, the control system 120 may provide a control signal to cut off the power supply of the distribution box 130 to the display screen body 110, and the power supply battery 140 starts to supply power to the display screen body 110, so that the power supply power of the external power supply is not increased due to the peak power consumption, and the power requirement of the display screen body 110 on the external power supply can be reduced.
It can be understood that the distribution box 130 is configured with an external power interface 131, and when the external power interface 131 is connected to a commercial power socket via a power cable, the distribution box 130 can supply power to the display screen body 110. In one or more embodiments, the power distribution box 130 is electrically connected to the power supply battery 140 and charges the power supply battery 140. Specifically, when the power supply battery 140 is in an idle state, the distribution box 130 may charge the power supply battery 140 until the power supply battery 140 is full; and when the power supply battery 140 supplies power to the display screen body 110, the distribution box 130 can also charge the power supply battery 140, so as to avoid the display of the display screen body 110 being affected by insufficient electric quantity of the power supply battery 140 caused by too long power supply time.
In particular embodiments, to avoid the switchbox 130 from charging the power supply battery 140 to boost the power of the external power source, the switchbox 130 only charges the power supply battery 140 during certain conditions. Specifically, when the power consumption of the display screen body 110 is smaller than a second preset value, or the power consumption of the display screen body 110 is larger than a first preset value, the distribution box 130 charges the power supply battery 140, wherein the second preset value is smaller than the first preset value. When the power consumption of the display screen body 110 is smaller than the second preset value, the external power supply supplies power to the display screen body 110 through the distribution box 130, and since the power consumption of the display screen body 110 is at a lower position relative to the average power consumption, the power supply power of the external power supply can meet the requirement of supplying power to the display screen body 110 and charging the power supply battery 140 at the same time; when the power consumption of the display screen body 110 is greater than the second preset value, since the external power supply supplies power to the display screen body 110 through the distribution box 130, if the distribution box 130 charges the power supply battery 140 at the same time, the power supply of the display screen body 110 may be affected, and therefore, the distribution box 130 does not charge the power supply battery 140 any more; when the power consumption of the display screen body 110 is greater than the first preset value, the power supply battery 140 supplies power to the display screen body 110, and the distribution box 130 does not supply power to the display screen body 110 any more, so that the distribution box 130 can charge the power supply battery 140, and the power consumption of the power supply battery 140 in the process of supplying power to the display screen body 110 can be avoided, thereby affecting the display of the display screen body 110.
Referring to fig. 1 and 2, in an embodiment, the power supply battery 140 may be disposed in the distribution box 130 or disposed on the display screen body 110. For example, when the display screen body 110 is a tiled display screen, the display screen body 110 includes a plurality of LED boxes, and each of the LED boxes may be configured with a power supply battery 140.
In the LED display system 10, by configuring the power supply battery 140, when the power consumption of the display screen body 110 exceeds a first preset value, the power supply side of the display screen body 110 is changed from the distribution box 130 to the power supply battery 140, and the power supply battery 140 completes the power supply in the peak stage. When the power consumption of the display screen body 110 is low, the external power source supplies power with low power through the distribution box 130, and the power supply power at this time only needs to refer to the average power consumption of the display screen body 110, for example, may be slightly larger than the average power consumption of the display screen body 110. When the power consumption exceeds the first preset value, the control system 120 may provide a control signal to cut off the power supply of the distribution box 130 to the display screen body 110, and the power supply battery 140 starts to supply power to the display screen body 110, so that the power supply power of the external power supply is not increased due to the peak power consumption, and the power requirement of the display screen body 110 on the external power supply can be reduced.
Referring to fig. 3, the present application further provides a power supply control method applied to an LED display system, which specifically includes the following steps:
s110: determining a peak power consumption and an average power consumption of the display screen body, and determining a first preset value;
when the display screen body is determined, the peak power consumption of the display screen body is determined, for example, when the display screen body is a monochromatic (such as green) lamp bead, all the lamp beads are controlled to display the monochromatic (green) lamp bead at the maximum brightness, and the power consumption of the display screen body is the peak power consumption at the moment; when the lamp beads are full-color lamp beads, all the lamp beads are controlled to display white with the maximum brightness, and at the moment, the power consumption of the display screen body is the peak power consumption.
In some of these embodiments, the first preset value may be determined based on the peak power consumption and the average power consumption. When the display screen body displays different images, the power consumption values are different, so that the average power consumption value is not a specific accurate value, and therefore, the average power consumption is only used for determining the first preset value. In a specific embodiment, the display screen body may be enabled to normally play a video, a power consumption curve of the display screen body is recorded, and the power consumption of the display screen body is maintained in a preset interval most of the time, so as to determine the first preset value, for example, the first preset value is between an average power consumption value and a peak power consumption value, and a value slightly larger than a maximum value of the preset interval is taken as the first preset value. Of course, a plurality of different videos can be played by the display screen body, the average power consumption of one display screen body is determined for each video, a final average power consumption value is obtained after appropriate weighting calculation, and then the first preset value is determined according to the final average power consumption value and in combination with the peak power consumption.
Of course, the first preset value may also be determined in other ways, for example, only by the peak power consumption or the average power consumption.
S120: acquiring a power consumption value of a display screen body;
in order to achieve the purpose of reducing the power of an external power supply for supplying power to the LED display system, different power supply sources of the display screen body need to be switched according to the first preset value, so that the external power supply is prevented from being used for supplying power near the peak power consumption. Since the power supply is real-time, it is difficult to switch the power supply source according to the time curve, and therefore, it is necessary to determine whether to switch the power supply source according to the power consumption value of the display screen body.
In some embodiments, the power consumption value of the display screen body is a real-time power consumption value of the display screen body. At this time, the step of obtaining the power consumption value of the display screen body specifically includes:
and acquiring the current real-time power consumption value of the display screen body.
When the display screen body displays a frame of image, the control system can detect the power consumption value of the display screen body in real time and takes the real-time power consumption value at the current moment as a reference value for judging whether to switch the power supply source or not.
In other embodiments, the power consumption value of the display screen body may be a predicted power consumption value of a next frame image. At this time, the step of obtaining the power consumption value of the display screen body specifically includes:
and predicting the power consumption of the display screen body when displaying the next frame of image, and acquiring the predicted value.
In a specific embodiment, the control system may predict the power consumption value of the next frame image based on the power consumption value in the historical time period, and use the power consumption value as the power consumption value of the display screen body. Because the video is formed by rapidly switching multiple continuous images, the same pixel point of two adjacent images is embodied as certain inheritance in brightness and color, the difference is not large, the same pixel point is embodied on a power consumption curve, cliff type rising or falling cannot occur, and generally the transition is gradual, so that the power consumption of the display screen body when the next image is displayed can be predicted according to the power consumption value of the current frame or the current frame in a close time period, and a predicted value close to the actual power consumption can be obtained.
Or, the control system may calculate the luminance information of each pixel in the next frame of image. For example, when the control system controls the display of the corresponding image, the control system correspondingly has a configuration file, which records the brightness information of the corresponding pixel points, each pixel point corresponds to a brightness value, each brightness value can correspond to a power consumption value, and the power consumption values of all the pixel points are integrated to obtain the power consumption value corresponding to the next frame image, which is the predicted power consumption value of the next frame image.
After the power consumption value of the display screen body is determined, the power consumption value of the display screen body can be compared with the first preset value, and therefore the corresponding power supply strategy is determined.
S130: and judging whether the power consumption value of the display screen body is larger than a first preset value or not, if so, cutting off a circuit between the distribution box and the display screen body to enable the power supply battery to be conducted with the display screen body so as to supply power to the display screen body by utilizing the power supply battery.
After the power consumption value of the display screen body is confirmed, the power consumption value of the display screen body is compared with a first preset value, if the power consumption value is higher than the first preset value, the display screen body is judged to be about to enter a power consumption peak value stage, at the moment, the power supply is switched to a power supply battery for supplying power, the display screen body is in the power consumption peak value stage in a time interval thereafter, until the power consumption is reduced to be lower than the first preset value, the power distribution box is switched to be connected with the display screen body, and power is supplied through an external power source. It can be understood that if the power consumption value is smaller than the first preset value, the first distribution box is continuously maintained to supply power to the display screen body.
Referring to fig. 4, in one or more embodiments, after step S130, the method may further include the steps of:
s140: when the power supply battery supplies power to the display screen body, the distribution box is controlled to charge the power supply battery.
When the power supply battery supplies power for the display screen body, the distribution box can also charge the power supply battery so as to avoid the phenomenon that the power supply battery is insufficient due to overlong power supply time and the display of the display screen body is influenced.
Referring to fig. 5, in one or more embodiments, the method may further include the steps of:
s150: when the display screen body is supplied with power through the distribution box, if the power consumption value of the display screen body is smaller than a second preset value, the distribution box is controlled to supply power to the rechargeable battery while supplying power to the display screen body.
The power supply power of external power source is invariable, the power consumption value of the display screen body is then in continuous change, when external power source charges to the power supply battery through the block terminal, form the reposition of redundant personnel to the power, consequently, in order to avoid causing the influence to the power supply of the display screen body, can define a second default, when being less than the second default, external power source's power supply can satisfy simultaneously for the power supply battery charge and charge for the display screen body, in order to guarantee at every turn when switching the power supply battery for the display screen body power supply, the power supply battery has sufficient electric quantity.
Referring to fig. 6, in one or more embodiments, step S130 may specifically include:
s131: judging whether the power consumption value of the display screen body is larger than a first preset value or not;
s133: if so, acquiring the power consumption value within a nearby preset time interval, and confirming the change trend of the power consumption value;
s135: if the trend is rising, controlling a power supply battery to supply power for the display screen body;
s137: if the trend is stable, acquiring a plurality of power consumption values larger than a first preset value in the time interval, judging the distribution condition of the plurality of power consumption values larger than the first preset value along with the time, if the power consumption values are distributed discretely, maintaining the power supply of the distribution box to the display screen body, and if the power consumption values are not distributed discretely, controlling the power supply battery to supply power to the display screen body.
The power consumption of the display screen body may fluctuate in an area near the first preset value, and at this time, if the power consumption value is just greater than the first preset value, the power supply battery is switched to supply power, and at the next moment, the power consumption value may be smaller than the first preset value, which may cause switching between the distribution box and the power supply battery. In order to avoid frequent switching, a group of power consumption values in a nearby time interval of the current video frame can be obtained, a power consumption value variation trend in the nearby time interval can be obtained according to the group of power consumption values, if the trend is increased, the power consumption value is also greatly increased in the next period of time, and therefore, a power supply battery is directly switched to supply power for the display screen body; if the trend is stable, extracting the power consumption value which is larger than the first preset value in the time interval, judging the distribution situation of the power consumption value which is larger than the first preset value along with the time, if the power consumption value is distributed discretely, indicating that the power consumption of the display screen body is larger than the first preset value only in a short period of time, and the power consumption value is immediately reduced to be smaller than the first preset value, and at the moment, in order to avoid frequent power supply switching, maintaining the power supply of the distribution box to the display screen body.
It can be understood that when the distribution box is used for supplying power to the display screen body, the power supply power of the external power supply can meet the power supply when the power consumption value of the display screen body is slightly larger than the first preset value, on one hand, the above strategy for avoiding frequent switching can be met, on the other hand, the sufficient power supply power can be provided when the power supply battery is switched, and insufficient power supply is avoided.
According to the power supply control method, when the power consumption of the display screen body exceeds a first preset value, the power supply of the display screen body is changed from the power distribution box to the power supply of the power supply battery, and the power supply of the power supply battery in a peak stage is completed. When the power consumption of the display screen body is low, the external power supply supplies power with low power through the distribution box, the power supply power at the moment only needs to refer to the average power consumption of the display screen body, when the power consumption exceeds a first preset value, the control system can give a control signal, the power supply of the distribution box to the display screen body is cut off, the power supply battery starts to supply power for the display screen body, therefore, the power supply power of the external power supply cannot be increased due to peak power consumption, and the power requirement of the display screen body on the external power supply can be reduced.
