Design And Implementation Of The System Software For An Air Defense Command Car

This paper is based on the needs and engineering approach, designed a low altitude defense command car software system which is used to a surface-to-air missile system. The software is developed with Visual C++ 6.0 and combined with MapX, have realized electronic maps, communication, data processing, threat assessment, target assignment, database design and other functions.First, analyze the application requirements of the defense command car software system, starting from the software design, give the overall system design and functional modules.Then, design communication module and data processing module of the system. Communication module includes: radio communication, multi-threaded serial communication class, udp network socket of radar data transmission; Data processing module analyzes and processes air situation information which has been received, changes radar target coordinates to GPS coordinates, calculates the indicator values which are used for threat assessment and firing advantage; use grey relational analysis to calculate the threat factor which the target relative to the launch car and sort of target, in the mean time follow firing advantages degree evaluation system shoot to calculate the firing advantages degree which launch car relative of target, on this basis optimize the allocation of the target. In addition, create SQL Server 2000 database which used to save air information, fully use of the advantage of the ADO wrapper class and ADO control.Finally, study geographic information system, and GIS base on MapX is the second developed, research e-map matching algorithm. Realize map zoom in, zoom out, roam, dynamic latitude and longitude, dynamic scale, dynamic goals and add trace, eagle-eye map, track playback and other functions.The system realizes the functions which are needed by the software of air-defense command car, and reaches the required purposes.
