Design Of Universal And Standardized Missile-borne Avionics

The traditional subsystems of missile-borne electronic system use separate design schemes and use decentralized management modes,which causes many problems.The size of the system is large.The power consumption is high.The relationship of interfaces is complex.The ability of reconfiguration is poor.The functional density is low.With the urgent demand for integrated and intelligent precision-guided system,optical system,radar system and communication system,it is an urgent task to research the universal and standardized missile-borne avionics.The main content of this thesis is as follows:1.The traditional typical subsystems of missile-borne electronic system are analyzed,such as radar system,communication system,navigation system and optical system.The similarities and differences of each systems are compared.On the basis of these points,a method is presented to design a universal and standardized missile-borne avionics.The avionics consists of some sensors,a central process unit and some actuators.On the basis of this method,this thesis reconstructs these subsystems and partition the specific functions of each module.2.On the basis of the integrated electronic design method,a heterogeneous multi-processor system based on Open VPX structure is presented.The modules of this system are connected by high-speed serial bus.The system consists of I/O modules,signal processing modules,calculation acceleration modules,control modules,mass memory modules and exchange modules.The key point of circuit design is introduced in detail.The hardware system is designed.3.On the basis of the hardware,the platform software is designed,including drivers and underlying applications.The software realizes the system monitor and control function,and the function of rapid data exchange through FPGA.The system can be reconfigured dynamically by software.Finally,the high-speed data interface is tested.The system is implemented on a missile-borne imaging project to verify the function.
