| Small-caliber antiaircraft gun is an important component of terminal defence system.As the development of computer simulation technology,the digital simulation and HIL simulation of antiaircraft gun system can simulate the process of practice drills,which becomes the data support of system demonstration,indices determination and key algorithm validation.This paper designed and implemented the terminal defence fire control simulator base on domestic embedded real-time multitasking system,which is capable of the validation of important algorithm and operational effectiveness evaluation as well as operation training.As the need of high real-time requirement of distributed antiaircraft gun system,domestic embedded real-time system is chosen as the development platform.The hardware structure of interface computer,task computer and 3D display computer is determined.Designed the software structure which can ensure the real-time cooperation of communication,information processing,hitting solving,barrel drive and ballistic calculation.As the need of networked artillery strike,designed the classification criteria based on unsupervised clustering method and target recognition method based on supervised classification method.Then threat assessment method based on combination weighting is chosen to evaluate the comprehensive situation,which compensate the lack of precision of subjective weighting and have great significance to cooperative engagement.Proposed the optimization method of the cooperation operation problem and multitasking problem of the fire control simulator.The performance of simulation system is proved to be improved.This paper implemented the fire control digital simulator based on domestic embedded real-time operation system.The timing accuracy,multitasking capability and system reliability of the embedded system are fully used.This paper provides some experience of the development of fire control simulator software base on domestic embedded real-time operation system.The use of domestic Sylixos system improves the timing accuracy,multitasking ability and operating speed of fire control simulator.This paper devote valuable experience of domestic fire control system development. |
