In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Realization of the invention is described in detail below in conjunction with specific attached drawing:
Fig. 1 shows power redundancy backup method provided by one embodiment of the invention, for ease of description, illustrates only
Part related to the embodiment of the present invention, details are as follows:
Firstly, power redundancy backup method provided by the embodiment of the present invention is mainly used for carrying out electricity to LED display unit
Source redundancy backup.
Specifically, referring to FIG. 2, Fig. 2 shows in power redundancy backup method provided by one embodiment of the invention
The modular structure of LED display unit 10.As shown in Fig. 2, the main needle of power redundancy backup method provided by the embodiment of the present invention
Pair be LED display unit 10 power supply, and the LED display unit 10 include N number of display area 100 (be with two in figure
Example), each display area 100 is provided with power supply 101, and power supply 101 is that display area 100 powers, and the output of power supply 101
Power is N/mono- of power consumption needed for LED display unit 10；Wherein, N is the positive integer not less than 2.
Further, as shown in Figure 1, power redundancy backup method provided by the embodiment of the present invention the following steps are included:
S101: the power supply output state of each display area is detected.
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 of at least one display area exports failure, disengagement failure power supply.
Wherein, in embodiments of the present invention, as shown in Fig. 2, each display area 100 has been provided with switch 102, the switch
102 connect with power supply 101, when the power supply 101 for detecting display area 100 exports failure, then control in display area 100
Switch 102 disconnects, to achieve the purpose that disengagement failure power supply 101.
S103: the input power consumption of LED display unit is obtained.
Wherein, in embodiments of the present invention, the input power consumption of LED display unit is obtained specifically:
The luminance parameter of LED display unit is detected, and corresponding input power consumption is obtained according to luminance parameter.
Specifically, since the different luminance parameters of LED display unit 10 correspond to different input power consumptions, it can pass through
Detect LED display unit 10 luminance parameter, and can according to the luminance parameter and corresponding input power consumption detected,
Obtain the input power consumption of LED display unit 10.
S104: if it is normal to control all outputs no more than the output power of each normal power supply of output for input power consumption
Power supply be LED display unit power supply.
Wherein, in embodiments of the present invention, after getting the input power consumption of LED display unit 10, it is necessary first to this
Input power consumption is detected, and when output power of the input power consumption no more than each normal power supply 101 of output, is then controlled
All normal power supplys 101 of output are the power supply of LED display unit 10.
For example, as shown in Fig. 2, LED display unit 10 is divided into two display areas 100, each display area 100 is
It is provided with a power supply 101, and the output power of each power supply 101 is two points of M watts of power consumption needed for LED display unit 10
One of, i.e., the output power of each power supply is 1/2M watts.As one in LED display unit 10 in two display areas 100
When the power supply 101 of display area 100 breaks down, the trouble power 101 is cut off, and obtain the defeated of LED display unit 10 at this time
Enter power consumption, and the input power consumption for working as the LED display unit 10 got is less than or equal to 1/2M watt-hour, then controls other one
Normal power supply 101 is exported in a display area 100 as the power supply of LED display unit 10.
It should be noted that being additionally provided with channel switch 103 on LED display unit 10, which is used for
When power supply 101 in the display area 100 of LED display unit 10 breaks down, with other display areas in LED display unit 10
It exports normal power supply 101 in 100 to connect, so as to export normal power supply 101 in other display areas 100 as power supply output
The display area 100 of failure powers, therefore, when the input power consumption of the LED display unit 10 got is less than or equal to 1/2M
Watt-hour then opens the channel switch 103, so that exporting normal power supply in the channel switch 103 and other display areas 100
101 form supply access, are realized in other display areas 100 of control with this and export normal power supply 101 as LED display unit 10
The purpose of power supply；The channel switch 103 can be set between display area 100, as shown in Fig. 2, the setting of channel switch 103 exists
