In order to realize low-power control of the LED display device, the embodiment of the application provides the LED display device and a low-power control method and control device thereof.
Next, a low power consumption control method of an LED display device according to an embodiment of the present application will be described first. The execution main body of the low-power-consumption control method of the LED display device provided by the embodiment of the application is an MCU (micro controller Unit) in the LED display device or a control device independent of the LED display device, the LED display device can be an LED television, an LED screen and the like, and is a display device with a personal computer function and a network communication function, a display panel of the display device is composed of LED lamp beads, and the LED display device comprises a power supply, a control Unit, a display Unit and an MCU. The manner of implementing the low power consumption control method of the LED display device provided in the embodiment of the present application may be at least one of software, a hardware circuit, and a logic circuit provided in the execution main body.
As shown in fig. 1, an embodiment of the present application provides a low power consumption control method for an LED display device, which may include the following steps.
S101, detecting the currently triggered sleep mode. If the currently triggered sleep mode is detected to be the shallow sleep mode, executing S102; if it is detected that the currently triggered sleep mode is the deep sleep mode, S103 is executed.
S102, outputting a first control signal to the power supply to control the power supply to cut off the power supply to the display unit, and outputting a second control signal to control the power supply to keep supplying power to the control unit.
S103, outputting the first control signal to the power supply to control the power supply to cut off the power supply to the display unit, and outputting the third control signal to control the power supply to cut off the power supply to the control unit.
By applying the scheme of the embodiment of the application, the LED display equipment is provided with the MCU, the MCU has the functions of detection and control, if a shallow sleep mode is detected, the power supply is controlled to be switched off by outputting a first control signal to the power supply, and the power supply is controlled to be kept supplying power to the control unit by outputting a second control signal, namely, the control unit can normally work and the display unit is switched off in the shallow sleep mode; if the deep sleep mode is detected, the power supply is controlled to cut off the power supply to the display unit by outputting a first control signal to the power supply, and the power supply is controlled to cut off the power supply to the control unit by outputting a third control signal, that is, in the deep sleep mode, both the control unit and the display unit are cut off. Therefore, the low power consumption control of the LED display device in shallow dormancy and deep dormancy is realized through the detection and the control of the MCU, and the power consumption of the LED display device in shallow dormancy and deep dormancy is reduced.
In the embodiment of the application, an MCU is additionally arranged in the LED display equipment, and the MCU has a low-power-consumption control function and mainly completes the receiving and sending of some control signals. The LED display device is provided with a key for triggering the sleep mode, or an infrared remote controller for controlling the LED display device is provided with a key for triggering the sleep mode, and the MCU can detect whether the sleep mode of the LED display device is triggered or not in real time, or detect whether the sleep mode of the LED display device is triggered or not at fixed intervals. Since the sleep mode is divided into the shallow sleep mode and the deep sleep mode, after it is detected that the sleep mode of the LED display device is triggered, it is necessary to further determine whether the triggered sleep mode is the shallow sleep mode or the deep sleep mode.
The control signals in the embodiment of the application include a first control signal, a second control signal, a third control signal and a fourth control signal, which can be level signals, and the level signals include a high level mode and a low level mode, which can be specifically set by user according to actual conditions.
In an implementation manner of the embodiment of the present application, S101 may specifically be: if the input signal of the designated key is detected to be low level and is still low level after the first preset time, determining that the sleep mode is triggered currently; if the continuous duration of the input signal of the designated key being at the low level does not reach a second preset duration, determining that the currently triggered sleep mode is a shallow sleep mode; and if the continuous time length of the input signal of the appointed key, which is at the low level, reaches a second preset time length, determining that the currently triggered sleep mode is a deep sleep mode, wherein the second preset time length is greater than the first preset time length.
If the input signal of the designated key is detected to be at a low level, in order to prevent false detection caused by software jitter, an anti-jitter time (for example, 50ms) with a first preset time duration may be set, and if the input signal of the designated key is detected to be at a low level and is still at a low level after the first preset time duration, it may be determined that the sleep mode is currently triggered. And then, continuously judging whether the triggered sleep mode is a shallow sleep mode or a deep sleep mode by utilizing a second preset time length, if the continuous time length of the input signal of the appointed key with the low level does not reach the second preset time length, determining that the currently triggered sleep mode is the shallow sleep mode, and if the continuous time length of the input signal of the appointed key with the low level reaches the second preset time length, determining that the currently triggered sleep mode is the deep sleep mode.
For example, whether the sleep mode of the LED display device is triggered may be detected every 10ms, and specifically, the sleep mode detection may be implemented by software, where the software is implemented as follows:
Figure BDA0003112564310000101
Figure BDA0003112564310000111

Specifically, a structure of an LED display device according to an embodiment of the present application is shown in fig. 6, where an AC signal represents an AC power supply, a DC signal represents a DC power supply, and an IO signal represents a General-purpose GPIO (General-purpose Input/Output). The function of each part is explained as follows:
power supply: the power supply module for supplying power to the whole machine comprises an input power supply AC1, a power supply DC1 for the control unit and the MCU, a power supply AC2 for the display unit, and a plurality of enable control signals (EN). Wherein when IO8 is high, AC2 turns on power supply, and low indicates AC2 stops supplying power; when IO7 is high, 12V DC outputs 12V, and when IO7 is low, the voltage is appropriately lowered (approximately 9V), further reducing power consumption.
MCU: in order to realize the sleep mode, an MCU is required to realize low power consumption control, and mainly complete the reception and transmission (IO) of some low-speed control signals.
A control unit: the video conversion system comprises a main control unit, an FPGA unit, a video conversion unit and a network conversion unit. The LED display device mainly realizes the conversion of common video signals into LED data streams to a display unit.
DC 1: the power supply independently supplies power for the direct current of the MCU, a DC-DC power supply chip is arranged in the middle, and 12V is converted into 3.3V to be supplied to the MCU for working. When IO7 is low, DC1 is 9V to 3.3V, further reducing the operating power consumption of the MCU.
DC 2: the power supply supplies 12V dc power to the control unit, but passes through a switching control unit. After passing through the switch control unit, the 12V DC power supply DC3 of the control unit is generated.
DC 3: when IO5 is high, DC3 and DC2 are open; when IO5 is low, DC3 is disconnected from DC2 and the control unit is powered down.
AC 1: the commercial power is connected with the power supply, and the commercial power is generally 220V alternating current.
AC 2: alternating current to the display unit. When IO8 is high, AC2 and AC1 are open; when IO8 is low, AC2 is disconnected from AC1 and the display unit is powered down.
IO 3: and a user key on the LED display device is used for entering the sleep mode. The specific implementation manner, for example, the short press enters the shallow sleep mode and the long press enters the deep sleep mode, may be defined by software, and is specifically implemented by the above method embodiment, and is not described here again.
IO 4: the dormant state indicator lamp can be defined according to the requirements of users. For example, the normal operation mode is green light, the shallow sleep mode is yellow light, and the deep sleep mode is red light.
IO1 and IO 2: and accessing signals of the infrared remote controller. The IO2 gives the MCU, only receives the code pattern of the standby key, shields the code patterns of other keys, and may define a specific implementation manner through software, for example, a short press enters shallow sleep and a long press enters deep sleep, which is specifically implemented according to the above method embodiment and will not be described herein again. The IO1 is a command unit for a remote controller to perform other control of the LED display device, such as adjusting sound and brightness, and masking the standby key code pattern.
The final achieved effect is as follows:
(1) under the normal power-on condition, a user key (or a remote controller standby key) is pressed for a short time, then the IO5 and the IO7 maintain the high level, the IO8 is changed from the high level to the low level, the display unit connected with the AC2 is powered off, and the shallow sleep mode is entered. The indicator light changes from green to yellow.
(2) Under the normal power-on condition, a user key (or a remote controller standby key) is pressed for a long time, so that the IO5, the IO7 and the IO8 are changed from high level to low level, the display unit connected with the AC2 is powered off, and the control unit connected with the DC3 is powered off. Only the MCU connected with the DC1 of the whole machine works normally, and at the moment, 12V of the DC1 becomes 9V, and the deep sleep mode is entered. The indicator light changes from green to red.
(3) In the shallow sleep mode, when a user key (or a standby key of a remote controller) is pressed for a short time, the IO5 and the IO7 continue to maintain a high level, the IO8 changes from a low level to a high level, the display unit connected with the AC2 is powered on, and the normal operation mode is entered. The indicator light changes from yellow to green.
(4) In the deep sleep mode, if a user key (or a standby key of a remote controller) is pressed for a short time, the IO5, the IO7 and the IO8 are all changed from low level to high level, the display unit connected with the AC2 is powered on, the control unit connected with the DC3 is powered on, and the DC1 and the DC2 are both 12V direct current, so that the normal operation mode is entered. The indicator light changes from red to green.
