Modeling decorative lamp with functions of redundancy and fault tolerance
Technical field
The present invention relates to a kind of lighting device, particularly relate to a kind of modeling decorative lamp.
Background technology
Lamp decoration is used as decorates extensive use, usually can using corresponding representative as decoration in various festival celebrations, to increase happy atmosphere; As on west Christmas Day, using various traditional designs as ornament lamp on Christmas Day, such as reinder, Christmas tree, Santa Claus, snowman, gift box etc.In the prior art modeling decorative lamp, can to each LED, control separately by built-in driving control chip, ornament lamp is changed various, make the red-letter day decorative effect better, but in prior art, the driving control chip of ornament lamp is all generally to adopt four signal controlling circuits to form a transmission channel to be controlled, when this transmission channel breaks down, signal transmission interrupts, and will have a strong impact on LED luminous, makes the ornament lamp cisco unity malfunction; And the function that reports an error of prior art chip, generally all can only be reported an error by indicator lamp, this mode, as in the heavy construction application, seemed directly perceived not, increases the difficulty that detects maintenance.
Redundancy refers to some parts of repeated configuration system, and when system breaks down, the work of trouble unit is got involved and born to the parts of redundant configuration; Fault-tolerant refer to system when its a certain component faults, still can continue the normal operation function, fault tolerance is generally to realize by redundant component.The technology that the assurance system breaks down or still can work during mistake at some part is called fault-toleranr technique.Can be divided into two classes from the fault of system: a class is " fatal ", impossible self-healing, and for example the critical piece of system all damages; Another kind of is local, may be repaired the mistake caused such as subelement inefficacy, line fault, accidental interference etc.Redundancy Fault-tolerant Technology utilizes redundant component to construct a kind of technology that can automatically get rid of the non-lethal fault just.
