[Abstract]:In this paper, based on the project of "XX gliding extended range missile technology", a missile computer hardware system based on DSP (TMS320C6747) is designed and implemented, and the software design and system debugging test are completed. The main work is as follows: (1) the overall scheme design. According to the working principle and overall structure layout of gliding extended range missile, as well as the function and performance requirements of the system, the design scheme of missile computer system is determined. (2) the design and manufacture of PCB hardware circuit board. Taking TMS320C6747 as the core, the schematic diagram design and PCB fabrication of the missile-borne computer system are completed, and the circuit board test is carried out. The anti-overload performance and hardware anti-interference of the missile-borne computer are taken into account in the PCB design. (3) the design and debugging of the system software. The software design of the system is completed by using modular design idea, and the functions of serial communication, A / D data acquisition, PWM waveform output, Nand Flash program loading (BootLoader) and SDRAM data reading and writing are realized by using hardware simulator to download and debug. (4) system debugging. The hardware circuit is tested and the functions of each software module are debugged, and the basic functions of missile-borne computer system, such as program download, program boot, serial port data transceiver and steering gear control, are tested. The test results show that, This design completes the system design requirements. This paper can provide technical support for the development of missile-borne computer for gliding extended range projectiles, and the related research results can be applied to conventional weapons such as artillery shells, rockets, terminal sensitive projectiles and so on.
