Description
Technical field
The utility model relates to the LED display field, specifically refers to a kind of Novel LED display screen.
Background technology
Along with the develop rapidly of LED technology, the LED display application is more and more extensive, for example various megastore, hotel, place of public amusement etc.LED display only is equipped with single power supply assembly and driver element usually at present, no matter power supply module or driver element, or corresponding connection line, use procedure there will be the damage fault unavoidably, and compare LED display unit, power supply module and driver element occur that the probability of damage fault is larger.When power supply module or driver element break down, while perhaps going wrong due to the somewhere circuit, at present way must be keeped in repair immediately, consuming time in maintenance, consumption power is loaded down with trivial details again, more crucial is to affect LED display demonstration effect in real time, thereby causes some unnecessary losses.
In view of this, the failure problems that the inventor exists for existing LED display conducts in-depth research, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of Novel LED display screen, adopts dual power supply dual drive system mode, after having avoided in prior art breaking down, brings various rough sledding, has greatly improved stability and the reliability of display screen normal operation.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of Novel LED display screen, mainly comprise LED display unit, switch control unit, detecting unit and two groups of power drives systems; The signal output part of this detecting unit is electrically connected to described switch control unit, and the control output end of this switch control unit and described LED display unit are electrically connected; Described two groups of power drives systems respectively include a power supply module and a driver element, the test side of this power supply module and driver element all is electrically connected to the signal input part of described detecting unit, and the output terminal of this power supply module and driver element all is electrically connected with described switch control unit.
The control input end of described switch control unit also is electrically connected with the PC controller.
After adopting such scheme, this Novel photo is for the beneficial effect of prior art: only use a group in two groups of power drives systems in work, wherein first group of work, for whole system power supply and driving LED display unit, is done for second group standbyly not work.When the first power supply module or first driver element of first group of power drives system of work goes wrong, the perhaps problem that breaks down of the circuit between them, after now by detecting unit, detecting instant detection relevant information, send corresponding signal to switch control unit, switch control unit is analyzed the laggard line correlation blocked operation of corresponding signal, by second source assembly and alternative corresponding out of order the first power supply module of the second driver element and second driver element of second group of power drives system.Thus, save the trouble that must keep in repair at once in the prior art, but also guaranteed LED display display effect in real time with can carrying out zero failure.
The accompanying drawing explanation
Fig. 1 is the theory diagram of this novel system structure.
Label declaration
Embodiment
Below in conjunction with the drawings and specific embodiments to originally being described in further detail.
This is novel relates to a kind of Novel LED display screen, as shown in Figure 1, mainly includes LED display unit 5, switch control unit 4, detecting unit 3 and two groups of power drives systems.These two groups of power drives systems are divided into the first power drives system 1 and second source drive system 2.This first power drives system 1 is comprised of the first power supply module 11 and the first driver element 12, and second source drive system 2 is comprised of second source assembly 21 and the second driver element 22.
As shown in Figure 1, the signal output part of detecting unit 3 is electrically connected to switch control unit 4, and the control output end of this switch control unit 4 is electrically connected mutually with LED display unit 5.The first power supply module 11, the first driver element 12, second source assembly 21 and the second driver element 22, their test side all is electrically connected to the signal input part of detecting unit 3, and their output terminals all are electrically connected with switch control unit 4.Detecting unit 3 is for detection of the failure condition of the first power supply module 11, the first driver element 12, second source assembly 21, the second driver element 22 and line related, and will detect relevant information convert signal to and send switch control unit 4 to.Switch control unit 4 is whole system work for controlling the first power supply module 11 or the first driver element 12, second source assembly 21 or the second driver element 22.
Only use a group in two groups of power drives systems in initial normal operation, i.e. wherein first group of power drives system 1 work, do standbyly not work for whole system power supply and 5, the second groups of power drives systems 2 of driving LED display unit.When the first power supply module 11 or first driver element 12 of first group of power drives system 1 of work goes wrong, the perhaps problem that breaks down of the circuit between them, after now by detecting unit 3, detecting instant detection relevant information, send corresponding signal to switch control unit 4, switch control unit 4 is analyzed the laggard line correlation blocked operation of corresponding signal, according to circumstances, perhaps by second source assembly 21, substitute the first power supply module 21 power supply is provided, perhaps by the second driver element 22, substitute the first driver element 12 with driving LED display unit 5, perhaps by second source assembly 21 and the second driver element 22, substitute corresponding out of order the first power supply module 11 and the second driver element 12 simultaneously.Even thereby in the situation that chance failure appears in system, by above-mentioned detection and handoff functionality, LED display still can be recovered normal operation in time, without on-site maintenance, accomplish that zero failure shows effect, greatly improved stability and the reliability of LED display normal operation.
This case Novel LED display screen utmost point is applicable to some extremely important occasions, can ensure the serviceable life of LED display.The shared volume of dual power supply drive system is little, lightweight.Detect handoff functionality and automatically control by the system corresponding units, without manually.Basically without being keeped in repair, saved the trouble of maintenance in use procedure, unless the external damage that causes due to external factor, or because environment badly causes.
In addition, for the ease of understanding constantly the system behaviour in service, and artificially manually whole system is controlled, the control input end of described switch control unit 4 also is electrically connected with PC controller 6.The operating personnel, by controlling PC controller 6, can either understand and control the working condition of whole system, maximizes and meets application demand.
The foregoing is only this novel preferred embodiment, all equalizations of doing with this novel claim scope change and modify, and all should belong to the scope of this novel claim.
