Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The present invention program aims to provide a kind of method for controlling power supply.Before carrying out power supply control, be sequentially each display unit that display unit set comprises and arrange identification number and waiting time, described display unit set comprises at least one display unit.Particularly, method for controlling power supply of the present invention comprises: do following process for each display unit, in order to start each display unit successively according to described identification number: start timing, and when timing arrives waiting time corresponding to described identification number, the display unit corresponding to described identification number is powered.
The present invention program is mainly applicable to large-scale display device, and so-called large-scale display device can be understood as the equipment comprising polylith LED/LCD display screen.Usually, can according to display subregion, display device is divided into multiple display unit, and each display unit can have the ability of being independently energized/cut-off capacity.In conjunction with actual division situation, display unit can comprise one piece of LED/LCD display screen, or display unit also can comprise polylith LED/LCD display screen, and the present invention can be not specifically limited this.
In actual applications, no matter be the display plan of establishment based on server controls, or based on the display plan of establishment of FMAS, all can relate to and powering to display device, start display device and carry out this problem of commodity displaying.Usually, large-scale display device is higher to power requirement, and the increase of the display screen number comprised along with display device, and equipment is also larger to the requirement of delivery, and powerup issue becomes restriction display device and to maximize a reason of development.For example, the output power of large-scale display device, is usually designed to the maximum starting power sum of all display screens.To comprise the display device of 15 pieces of display screens, if the maximum starting power of one piece of display screen is 1000 watts, so, when doing power-supply service for this display device, at least need 15*1000=15000 watt.Along with the increase of display screen number, this power-supply service also linearly increases.
Inventor finds in actual applications, display device communicating with miscellaneous equipment (as, the any equipment with display device with correspondence of controller, memory device, FMAS etc.) before, each display screen is all to complete energising via self startup checking and initialization, also namely, without the need to powering to all display screens simultaneously.Based on this, it is display unit set that the present invention program can divide display device in advance, and wherein, display unit set comprises at least one display unit.
As an example, the display unit of mapping relations can be had by with same FMAS, be divided in a display unit set; Or, can according to the position of display unit, be divided into by adjacent display cell in a display unit set, the present invention can be not specifically limited this.
Below to control the start-up course of each display unit in a display unit set, the present invention program is explained.
(1) for each display unit arranges a corresponding identification number and waiting time.
Identification number is for identifying the identity of display unit, and the boot sequence of display unit in set; Waiting time for representing the interval time between device start to display unit energising, by arranging waiting time, can the object that is sequentially energized of each display device of control realization.It should be noted that, the identification number that display unit is corresponding and waiting time, automatically can be configured according to actual needs by power supply control apparatus, or, also can carry out default configuration by Default Value; Or power supply control apparatus also can communicate with the external world, and carry out far-end configuration according to the information of external world's input, the present invention can be not specifically limited this.
In the present invention program, identification number can be presented as the ID of display unit, or, also can be presented as the positional information (e.g., display unit place line number and row number) of display unit.For example, display unit set comprises 6 display units, and each display unit comprises one piece of LED display, if 6 pieces of LED display are specifically distributed as the rectangle that 2 row * 3 arrange, each display unit can be identified by No. ID 1,2,3,4,5,6, also by ranks number (1,1), (1,2), (1,3), (2,1), (2,2), (2,3) identify each display unit.
In the present invention program, the waiting time that each display unit is set that can be regular, or, the waiting time of each display unit also can be irregularly set.For example, arrange and start gap periods T, then the difference of the waiting time between adjacent two display units in boot sequence is T, as, the waiting time of display unit 1 correspondence is T, and the waiting time of display unit 2 correspondence is 2T, by that analogy, the waiting time of display unit 6 correspondence is 6T.Or, waiting time corresponding to each display unit can be irregularly set, that is, the difference of the waiting time between adjacent two display units in boot sequence is not necessarily identical, as, the waiting time of display unit 1 correspondence is 1/10s, the waiting time of display unit 2 correspondence is 2/10s, and the waiting time of display unit 3 correspondence is 4/10s, and the waiting time of display unit 4 correspondence is 5/10s, the waiting time of display unit 5 correspondence is 8/10s, and the waiting time of display unit 6 correspondence is 9/10s.
For example, in the present invention program, at least arrange by circuit shown in Fig. 1 and start gap periods T.Particularly, by the mode of adjusting resistance R1 and/or electric capacity C1 value, arrange and start gap periods T.As, R1=47K ohm, C1=0.1 μ farad, then T=R1*C1=47K*0.1 μ=0.0047 second.Or, the combination of other resistance and electric capacity also can be introduced on the basis of R1 and C1, adjust with this and start period distances T, as shown in Figure 1, also introduce R2 and C2, if R2=470K ohm, C2=10 μ farad, T=R1*C1+1.1*R2*C2=47K*0.1 μ+1.1*470K*10 μ=0.0047+5.2=5.2047 second.
(2) according to waiting time, display unit corresponding to this waiting time is started successively.
In the present invention program, between waiting time and identification number, there is corresponding relation, like this, timing is started when device start, once arrive a waiting time, just can search the identification number knowing that this waiting time is corresponding, and then whom the clearly current display unit needing power supply is.
For example, when timing arrives T, just can know corresponding with this waiting time to be ID be 1 display unit, can control to power to display unit 1, so analogize, till starting 6 display units successively.It should be noted that, start moment it is desirable that start the maximum starting power of display device 1.
It should be noted that, if just two display devices have identical waiting time, the waiting time as display unit 5 and 6 correspondence is 5T, then illustrate and need to start display unit 5 and 6 simultaneously, so, when timing arrives 5T, can control to power to display unit 5 and 6 simultaneously.It should be noted that, start moment it is desirable that start the maximum starting power of display device 5 and 6.
Alternatively, when there is multiple display unit set, also can be each display unit set and a corresponding numbering is set, that is, the boot sequence of display unit set is set.
According to the present invention program, each display unit of sequential start, just can reduce the designing requirement of equipment to output power, realizes the object of saving output power.This mainly because, when display device starts laggard row commodity displaying, parts in equipment (as, display screen, hub etc.) operating voltage only need a relatively low DC voltage, that is, the actual motion power after display device startup is less than the maximum starting power of display device.If conventionally, in order to meet the output power of device start moment, and the output power of equipment is designed to the maximum starting power sum of all display screens, so, in long-play process after display device starts, then can cause the waste of output power, and be unfavorable for the maximization development of display device.If according to each display unit of the present invention program's sequential start, then the output power of equipment can be designed to display unit number N+ actual motion power * (display unit total number M-N) that the maximum starting power * of P=starts at most simultaneously.
To start each display unit (i.e. N=1) one by one, for above lift the display unit set comprising 6 display units, if the maximum starting power of each display unit is 1000 watts, actual motion power is 500 watts, then, in prior art, the output power of equipment is 6*1000=6000 watt, and in the present invention program, the output power of equipment is 1000+500*5=3500 watt, hinge structure scheme, the present invention program can save 2500 watts.So, under identical output power design, the present invention program allows display device to comprise more multi-aspect unit; In addition, if display device comprises identical number display unit, the present invention program reduces output power, also help protection display device not destroy by surge voltage.
Particularly, in the present invention program, power supply control apparatus at least by following two kinds of modes, is powered to display unit: power supply control apparatus can directly and display unit communicate, when waiting time arrives, controlled to power to the display unit of correspondence by power supply control apparatus.Or power supply control apparatus can communicate with FMAS, when waiting time arrives, first determine and the current FMAS needing the display unit of powering to have mapping relations, then control to power to display unit via this FMAS.
It should be noted that, the FMAS in the present invention program can be presented as schematic diagram shown in Fig. 2, comprising: physics input/output interface 201, for carrying out data interaction with the external world; At least two flash memory modules 202, store for the serial or parallel realizing data; Comprise the flash array controller 204 of a block map unit 203, for preserving the mapping relations between logical address and physical address, wherein, physics input/output interface carries out data interaction with extraneous by logical address, and data interaction is carried out by physical address in physics input/output interface and array inside.In addition, flash array controller also can be preserved, the mapping relations between flash memory module and display unit, and particularly, mapping relations therebetween can be understood as, the merchandise news that display unit is preserved for showing the flash memory module that there is mapping relations with it.In the present invention program, with display unit, there is mapping relations FMAS and refer to FMAS belonging to the flash memory module with display unit with mapping relations.
Alternatively, in display device shutdown or when restarting, power supply control apparatus also can do following process for each display unit, in order to close each display unit successively according to described identification number: start timing, and when timing arrives waiting time corresponding to described identification number, stop the display unit to described identification number is corresponding to power.So, contribute to equally protection display device not destroy by surge voltage.
Alternatively, power supply control apparatus also can do following process: the power supply information being gathered described display unit by the described FMAS with mapping relations after controlling to complete power supply to each display unit; Calculate the actual power information of described display unit set according to the power supply information of each display unit, and compared with default power supply information, obtain failure diagnosis information; The described failure diagnosis information of long-range transmission.
In the present invention program, power supply information when each display unit normally runs can be identified, if display unit breaks down, is bound to affect to some extent its power supply information, and also, power supply information during display unit fault is different from power supply information during normal operation.Based on this, power supply control apparatus can the power supply information of each display unit of Real-time Obtaining, and carry out fault diagnosis with this to each display unit.For example, power supply information can be embodied as voltage, power etc., and the present invention can not limit this.
As a kind of example, power supply control apparatus can obtain the actual power information of each display unit one by one, and compared with the default power supply information corresponding with this display unit, if the two conforms to (in the present invention program, conform to identical both can be understood as, or deviation therebetween meets preset range), then can obtain the normal fault diagnosis result of this display unit; If the two does not conform to, then can obtain the fault diagnosis result of this display unit exception.
Or, as a kind of example, in order to improve the fault diagnosis efficiency of the present invention program, electric supply installation can obtain the actual power information of each display unit in display unit set, and calculate actual power information corresponding to display unit set accordingly, compared with default power supply information corresponding with display unit set again, if the two conforms to, then can obtain all normal fault diagnosis result of each display unit in this set; If the two does not conform to, then can obtain the fault diagnosis result comprising abnormal show unit in this set.So, by once comparing, the fault diagnosis of whole set can be realized, improve diagnosis efficiency.Alternatively, when the two does not conform to, also as required, one by one fault diagnosis can be carried out to each display unit in set, finds out described abnormal show unit, realize localization of fault.In addition, it should be noted that, the actual power information of display unit set is calculated according to the power supply information of each display unit, be specially: if the power supply information of display unit and default power supply information adopt same units, then process is summed up to the power supply information of each display unit, obtain the actual power information of display unit set; If the power supply information of display unit and default power supply information adopt not commensurate, then after first Conversion of measurement unit being carried out to the power supply information of each display unit, then sum up process, obtain the actual power information of display unit set.
It should be noted that, in above-mentioned two examples, if power supply control apparatus is direct and display unit communicates, power supply control apparatus directly can gather the power supply information of each display unit, carries out fault diagnosis; Or if power supply control apparatus and FMAS communicate, power supply control apparatus gathers the power supply information of display unit by FMAS, and the present invention program can be not specifically limited this.
Actual motion power voltage to be identified and to show, or be sent to control system by selectivity FPDP.This just allow for remote monitoring and fault diagnosis.Because at a node, the maximum load power of electronics is that constant (such as all lamps are all bright, and under the brightness case of 100%), if the so current maximum load voltage at arbitrary node is less than known maximal value (under same certain situation), some lamps of proof or module break down (large LED shields modal problem) by that.This just allows by the monitoring of NAPA routine and the remote diagnosis to LED display.
Because great majority have the LED display of the element broken down to change to the meeting of source voltage requirements, in the rack array of a large display screen, NAPA comes report load voltage or demand voltage, for remote diagnosis by its FPDP.This information improves the function of large LED flash memory module array system softpanel.
Alternatively, need in conjunction with practical application, described failure diagnosis information can comprise fault diagnosis result and/or localization of fault information.Wherein, fault diagnosis result can be embodied as normal or abnormal, and localization of fault information can be embodied as the identification number of display unit or display unit set.
Alternatively, if described failure diagnosis information comprises localization of fault information, power supply control apparatus also can do following process: according to described localization of fault information, determines the FMAS with fault display unit with mapping relations; Control described fault display unit by the FMAS determined and carry out fault pre-alarming.That is, judge to there is fault display unit (namely at power supply control apparatus, the fault diagnosis result of this display unit is abnormal) time, also can control this fault display unit and carry out fault pre-alarming, particularly, fault display unit carries out fault pre-alarming by modes such as word, sound, light, flickers, and the present invention can be not specifically limited this.
