某战术训练模拟器快速校准数据采集系统

A Fast Calibration Data Acquisition System of Tactical Training Simulator

某战术训练模拟器数据采集采用现场总线方式,由主控计算机作为上位机,两个单片机控制盒作为下位机。通过采用RTX实时操作系统产生精确定时,同时以事件驱动的方式实现数据采集程序同步运行,通过485总线在数据采集程序与2个单片机控制盒之间实现应答式数据通信,从而实现数据采集系统与主时钟的完全同步。设计了模拟量输入数据采集表的人工改写功能,实现了能够自动更新模拟量输入数据采集表的快速校准方法,满足了操纵机构模拟量输入数据实时性、可靠性、维护校准高的要求。

Data collection of the tactical training simulator uses field bus technology. Main control computer is host machine,two single chip microcomputer control box are under machine. The system produces precise timing by using RTX real-time operating system,at the same time drives joystick program in the form of event driven,realizes data communication between the joystick program and two single chip microcomputer control box through the 485 bus.The system realizes complete synchronization between the data acquisition system and the main clock. The system designes the mode that the data collection table can be artificial rewrited,realizes the fast calibration method that the data collection table can be automatically updated. The operation data requirements are well satisfied,such as real-time ,reliability,maintenance.
