Guided Bombs And Aircraft Fire Control System, Cross-linked Research And Design

With the progress and development of science and technology, precise guided technology makes considerable progress and development. Ordinary aerial bombs are transformed into guided bombs by installing guided and control additional.It can not only improve a large amount of ordinary bomb into a guided bomb with a few investments but also improve fight performance greatly.These texts go on research and design the crosslinking between guided bomb unit (GBU) and aircraft fire control system in order to that solves these problems of hanging model, data communication, transfer alignment and throwing guided bomb etc. It mostly research and design the 1553B hardware interface between GBU and aircraft fire control system and the embedded software of the system. It analyzes to the designed system by simulating test through the artificial platform.The thesis has put forward the systematic design plan by systematic analysis between GBU and aircraft fire control system. True dual-port RAM configuration is used to solve the systematic real-time character problem and confirm the design of the 1553B hardware interface by that analyzes the structure and function of DSP C6713 chip, 1553B agreement chip UT1553B BCRT and pairs of RAM CY7C025 and compare the pseudo dual-port RAM configuration, DMA configuration and true dual-port RAM configuration of hardware interface between UT1553B BCRT and C6713. Designing the embedded software of the system , it firstly solve self-examining and initial state of the systematic hardware,and then design the drive of UT1553B BCRT that analyzes and designs the problem of receiving and sending message, dealing with interruptions etc. It finishes lastly the crosslinking flow btween GBU and aircraft fire control system.Utilizing the artificial platform of aircraft fire control system in the laboratory, interface hardware and embedded software of system are carried on a series of test. Data between GBU and fire control system transmits steadily and result of transfer alignment is greatly ideal.Simulated bombing can go on, indicating that the crosslinking is normal between GUB and aircraft fire control system.Design of systematic hardware and embedded software are reasonable and can suffice requirement of system.
