Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and
It is not used in the restriction present invention.
It is described in detail below in conjunction with realization of the concrete accompanying drawing to the present invention：
Fig. 1 shows the power redundancy backup method that one embodiment of the invention is provided, and for convenience of description, illustrate only
The part related to the embodiment of the present invention, details are as follows：
First, the power redundancy backup method that the embodiment of the present invention is provided is mainly used in carrying out electricity to LED display unit
Source redundancy backup.
Specifically, Fig. 2 is refer to, Fig. 2 is shown in the power redundancy backup method that one embodiment of the invention is provided
The modular structure of LED display unit 10.As shown in Fig. 2 the main pin of power redundancy backup method that the embodiment of the present invention is provided
To be LED display unit 10 power supply, and the LED display unit 10 (is with two in figure including N number of viewing area 100
Example), each viewing area 100 is provided with power supply 101, and power supply 101 is powered for viewing area 100, and the output of power supply 100
N/mono- of power power consumption for needed for LED display unit 10；Wherein, N is the positive integer not less than 2.
Further, as shown in figure 1, the power redundancy backup method that the embodiment of the present invention is provided is comprised the following steps：
S101：Detect the power supply output state of each viewing area.
Wherein, in embodiments of the present invention, power supply output state includes that power supply output normally exports two kinds of failure with power supply.
S102：If the power supply output failure of at least one viewing area, disengagement failure power supply.
Wherein, in embodiments of the present invention, as shown in Fig. 2 each viewing area 100 has been provided with switch 102, the switch
102 are connected with power supply 101, when the power supply 101 for detecting viewing area 100 exports failure, then control in viewing area 100
Switch 102 disconnects, so as to reach the purpose of disengagement failure power supply 101.
S103：Obtain the input power consumption of LED display unit.
Wherein, in embodiments of the present invention, the input power consumption for obtaining LED display unit is specially：
The luminance parameter of detection LED display unit, and corresponding input power consumption is obtained according to luminance parameter.
Specifically, due to the input power consumption that the different luminance parameters correspondence of LED display unit 10 is different, therefore, can pass through
The luminance parameter of detection LED display unit 10, and can just may be used according to the luminance parameter for detecting and corresponding input power consumption
Obtain the input power consumption of LED display unit 10.
S104：If input power consumption is not more than the output of each normal power supply of output, all outputs are controlled normal
Power supply power for LED display unit.
Wherein, in embodiments of the present invention, after the input power consumption of LED display unit 10 is got, it is necessary first to this
Input power consumption is detected, and when the input power consumption is not more than the output of each normal power supply 101 of output, is then controlled
The normal power supply 101 of all outputs is powered for LED display unit 10.
For example, as shown in Fig. 2 LED display unit 10 is divided into into two viewing areas 100, each viewing area 100 is equal
It is provided with a power supply 101, and the output of each power supply 101 is two points of power consumption M watt for needed for LED display unit 10
One of, i.e., the output of each power supply is 1/2M watts.One in two viewing areas 100 in LED display unit 10
When the power supply 101 of viewing area 100 breaks down, the trouble power 101 is cut off, and obtain the defeated of now LED display unit 10
Enter power consumption, and when the input power consumption of the LED display unit 10 for getting is less than or equal to 1/2M watt-hours, then control other one
Export normal power supply 101 in individual viewing area 100 to power for LED display unit 10.

When power supply 101 in the viewing area 100 of LED display unit 10 breaks down, with other viewing areas in LED display unit 10
Export normal power supply 101 in 100 to connect, so as to normal power supply 101 is exported in other viewing areas 100 for the power supply output
The viewing area 100 of failure powers, therefore, when the input power consumption of the LED display unit 10 for getting is less than or equal to 1/2M
Watt-hour, then open the channel switching 103 so that exports normal power supply in the channel switching 103 and other viewing areas 100
101 form supply access, realize controlling to export normal power supply 101 as LED display unit 10 in other viewing areas 100 with this
The purpose of power supply；The channel switching 103 can be arranged between viewing area 100, as shown in Fig. 2 channel switching 103 is arranged on
Between two viewing areas 100, it is also possible to be arranged on the other positions of LED display unit 10, such as a left side for LED display unit 10
Edge placement, is not particularly limited herein.
In the present embodiment, by the way that LED display unit 10 is divided into into N number of viewing area 100, each viewing area 100
It is respectively provided with power supply 101, and N/mono- of the output of each power supply 101 power consumption for needed for LED display unit 10 so that
Output for the power supply 101 of the power supply of LED display unit 10 declines, and reduces the requirement to the output of power supply 101, you can
To be realized using more low power power supply, so as to while the power redundancy backup of LED display unit 10 is realized, reduce electricity
The cost of source redundancy backup.
