Brief description of the drawings
, below will be to embodiment or existing in order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
The embodiment of application, for those of ordinary skill in the art, on the premise of not paying creative work, can also basis
The accompanying drawing of offer obtains other accompanying drawings.
Fig. 1 is a kind of structural representation of DLP products；
The method flow diagram that a kind of DLP products that Fig. 2 is provided by the embodiment of the present application are powered；
A kind of method schematic diagram for division power supply area that Fig. 3 is provided by the embodiment of the present application；
The system structure diagram that a kind of DLP products that Fig. 4 is provided by the embodiment of the present application are powered.
Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application
In accompanying drawing, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described embodiment is
Some embodiments of the present application, rather than whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belong to the scope of the application protection.
It refer to Fig. 1, the method flow diagram that a kind of DLP products that Fig. 1 is provided by the embodiment of the present application are powered, specific skill
Art scheme is as follows：
S101：The unit screen of the DLP products is divided into power supply area；
The purpose of this step is in order that with centrally connected power supply, to how to divide the unit screen of DLP products and be not construed as limiting.This
The unit screen at place refers to a projecting cell, implies that and refers to each projecting cell being divided into a power supply area.
Preferably, the unit screen of divided by column DLP products can be used.Because in actual use, DLP products be all by
Some unit screens assemble, and DLP products are generally more than height, the i.e. bottom side length of rectangle DLP products for the demand of length
Degree is generally longer than vertical edge.Therefore the unit screen of divided by column DLP products is easier to install, tested and the dimension in later stage
Shield.For example, when needing 4*8 DLP products, when configuring electric power system, 4 unit screens of each row can be set to one
Power supply area, then a total of 8 power supply areas of the DLP products.Can also be by the unit screen region of suitable shape as service area
In domain, such as Fig. 31,2,5,6 composition regions be used as power supply area, with { 1,2,5,6 } expression, then { 3,4,7,8 }, 9,
10,13,14 }, { 11,12,15,16 } are remaining power supply area
Certainly, how to divide power supply area will also be with the corresponding actual conditions of DLP products depending on, select right quantity or conjunction
The unit screen region of conformal shape will be advantageous to install as power supply area, test and the maintenance in later stage.
It is noted that it can not only use a power-supply system using whole DLP products as a power supply area here
Power supply, because can so make, the consumption of DLP current bus is quite big, and circuit also will be considerably long, and power consumption is higher.Furthermore, it is also possible to go out
Existing power-supply fluctuation, the situation of DLP products response failure.Even for cost, only powered with a power-supply system, it is also necessary to examine
Consider transformation problem, cost is also higher.And divide power supply area and simply use subregion centrally connected power supply, circuit is influenceed not
Greatly, the problem of such is not had.
S102：Powered for power-supply system corresponding to each power supply area use；Wherein, the power-supply system includes negative
Carry circuit and redundant load circuit；
After power supply area has been divided through S101, powered in each power supply area using a power-supply system.Relative to
For the power-supply system of prior art, the power-supply system in the application can provide two voltage bus, and one is standby voltage,
Another is load voltage.Load voltage is allowed to start shooting by opening instruction when meeting that start requires.In addition, the power supply in the application
System possesses redundancy feature, that is, provides redundant load circuit, for when main load circuit breaks down, taking over main load electricity
Road powers for unit screen.The quantity of redundant load circuit is not construed as limiting herein, should be depending on actual conditions demand.Example
Such as, such as Fig. 3, after divided by column power supply area is taken, redundant load circuit can be N+1, N+2, N+3, N+4, and N+4 is with regard to suitable
Broken down in prevention least ideal situation, the i.e. equal power supply circuit of the four of the power supply area unit screen.But actually using
In, because can regularly overhaul, therefore the supply line of Individual cells screen breaks down and has belonged to cas fortuit, is this redundant load electricity
Road be not usually required to it is consistent with actual power number of, lines, should be by those skilled in the art rule of thumb or actual conditions are determined
It is fixed.Certain redundant load circuit is more, and reliability is higher.
Here a power supply area described herein is explained using a power-supply system.In the prior art, often
Individual unit screen has single power-supply system to be powered for it, then detection unit screen is corresponding one by one for needs when installing, debug and safeguarding
Power-supply system.And the power-supply system quantity that the same amount of unit screen needs of the application operate is then relatively few a lot, improves
Installation, debugging and the efficiency safeguarded.
S103：Judge whether the power supply status of the unit screen is normal；
This step is directed to during use, and whether the power supply status of judging unit screen is normal.Judgement is not limited herein
Method, as long as the whether normal method of power supply status of energy judging unit screen all should be in the protection domain of the application.It is preferred that
, the state of each unit screen can be monitored in real time using Master Control Center.It is in place that power supply status includes number of power sources, power supply
Situation, power supply output state and power alarm information etc..Can be shown in by the interface software of Master Control Center on screen so as to
Monitoring in real time.
S104：If abnormal, the redundancy exchanged in power-supply system corresponding to the power supply area belonging to the unit screen
Load circuit is powered.
When the circuit malfunctions of unit screen, power supply corresponding to the power supply area belonging to the unit screen should be exchanged in time
Redundant load circuit in system is powered for it, avoids the occurrence of blank screen.
The embodiment of the present application provides a kind of method of DLP products power supply, be able to can be realized to DLP by the above method
The independently-powered of product is optimized for centrally connected power supply, and realizes the power supply status of monitoring each unit screen, avoids the occurrence of using failure, subtracts
Lack system cost, improve installation, debugging and the efficiency safeguarded.
