Study Of Guidance Target Ground Test And Parameter Setting System

Before target guidance performs a flight mission, trajectory calculation and the ground fault diagnosis and parameter setting must be completed. The thesis adopts VC++to realize ground test and setting software design of the parameter. Through the communication between the software and the computer, and test towards the various modules of target system, and providing target trajectory parameter with the computer, the software will ensure a successful completion of the mission.The main content of the thesis is divided into six parts as follows:(1) Overall plan research about Guidance target ground test and parameter setting system. System is set up by a serial port module, fault diagnosis module, parameters setting module, the automatic calibration module, the yaw test modules and confirm the launch module.(2) Guidance target ground test and parameter setting system and the computer communication program design adopt Serial control with MSComm to realize the control of serial interface and to send and receive data.(3) The design of fault diagnosis system includes reading and fault judgment, four-way navigation parameters steering state detection and target automatic detection guidance and control system for power supply state.(4) Programming of the Target parameter setting system realizes the target trajectory parameter’s input and to download it on the computer.(5) The design of the flight trajectory parameters automatic calibration program, mixed with VC++programming based on MATLAB, realizes the simulation of the target flight trajectory parameters and gets the target trajectory simulation2d figure, realizes the target trajectory parameters calibration function.(6) The design of the target yaw test program, adopting a cycle manner to to send commands to the the computer, by receiving the feedback of yaw value from the computer, is to realize calibration of the yaw value calculation method.The software function is tested, through the debugging between the guided target ground test and parameter setting system connected to the computer control system,Test results show that the design can succeed in the requirements of various functions of the software.
