Description
Technical field
The utility model relates to the detection technique of lighting device, relates in particular to a kind of LED pick-up unit.
Background technology
At present, development along with the LED display technique, LED display application and LED lamp decoration brightening application are low because of its energy consumption, color reducibility is strong, the characteristics such as life-span length, enormous size, exotic shape, be applied to more and more widely various occasions, in the middle of these were used, fault detection technique also more and more embodied its importance.The LED display application in the great occasion particularly because of its movable importance, thereby shows that to LED the requirement of the judgement of fault and maintenance is also higher.
In the middle of current LED display application, although having recognized LED, users show the significance of fault detection technique, leading firm is also in the research and development of having carried out in varying degrees fault detection technique both at home and abroad.But be limited by the technical strength various factors, present fault judgement focuses mostly in visual inspection and micro-judgment, and detection means also stays in the offline inspection means such as multimeter, oscillograph, efficient is low, weak effect, and detection means falls behind, levels of precision is not high, and intelligent level is low.The contradiction of widespread popularity and fault-detecting ability deficiency is also more and more outstanding.
The utility model content
The purpose of this utility model is for defects, provides a kind of fault-detection data accurate, and detection efficiency is high, the LED pick-up unit that intelligent level is high.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of LED pick-up unit comprises a pcb board, and is arranged on LED display terminal, detection module, memory module, message processing module, signal correction unit on the pcb board; Described detection module comprises electro-detection module and signal detection module; Described memory module comprises the first memory module and the second memory module, described electro-detection module is connected with each element in the described LED display terminal by power lead, for detection of the status of electrically connecting of each element, generate the status of electrically connecting data, store described memory module into; Described signal detection module is connected by each element that is connected with the signal input in signal wire and the described LED display terminal, and for detection of the signal connection status of each element, generation signal connection status data store described memory module into; Terminal link information processing module in described the first memory module and the second memory module; Described signal correction unit is connected with each led module on the LED display terminal by signal wire; Described signal connects and comprises that side signal transmission is connected with secondary signal to opposite first signal connection, is used for transmitting respectively the control signal of each led module.
One signal also is set on the described LED pick-up unit connects converting unit, be connected with described message processing module, be used for selecting first signal to connect, or when described first signal connects fault, select described secondary signal to connect.
The LED pick-up unit that the utility model provides, the position and the fault type that can failure judgement occur, intelligent level is high, and this pick-up unit detects simple to operate, and detection efficiency is high.
