The Design And Implement Of Fiber Fusion Based On BF561

Fiber is one of the most important transmission medium in communication.It has many advantages such as wide transmission bandwidth,low loss, large capacity, no electromagnetic interference,abundant raw materials and so on.When the damage of fiber cables occurred,it is needed to be repaired.Nowdays the most used method is fiber fusion.It is necessary to ensure that two sections of the fiber are precisely aligned to ensure full integration and same density. Or else there will be refraction and reflection to reduce the communication quality. The Design and implementation of fiber fusion system based on Blackfin 561 is discussed in the paper.This system can automatically make the fiber fused according to the sampled images and the menu set.By switching output screen, the situation of the actual fusion can be observed in vertical and horizontal direction.The development of fiber fusion is introduced in the first.After that the design of the separate mold and the whole hardware are offered.The system is divided into three parts, the power mold, the DSP processing mold and I/O interface mold. The power mold is in charge ofthe switch of battery and 220V AC.The DSP mold is responsible for the video imagesampling,data processing,character overlaying and other realization of functions or corealgorithms.The I/O interface mold controls the keyboard,the motor,the heat sources and so on.Then the method of adjusting the electric circuit of the system in order to make the PCB is discussed.At last the hardware debugging method are presented, the software image processing methods are discussed and the preliminary system accuracy is analysed.
