基于CPLD的模拟弹丸信号发生器的设计

设计一种特定的脉冲序列信号发生器,以模拟自动武器在连发或霰弹射击状态下弹丸过靶产生的脉冲信号,并用此脉冲信号发生器对VXI测速模块进行校准。利用EDA技术设计核心信号发生电路,所设计的信号发生器能够对输出脉冲信号的个数和频率进行控制,并可通过数据选择电路控制输出为规则脉冲信号还是随机脉冲信号,最后利用MAX＋PLUS‖软件对其进行验证,给出了时序仿真图。实际现场试验证明该信号发生器完全满足设计要求,可较好地用于模拟自动武器的各种射击状态。

Design of signal generator simulate projectiles based on CPLD

The design of a signal generator which can simulate the pulse signal generated when projectiles passing through a target at the state of automatic fire or canister fire,and use the signal generator to calibrate the VXI velocity measurement module.The design of core signal producing circuit is based on EDA technology.The signal generator designed can not only control the number and frequency of output pulse signal,but also decide whether the output signal is regular or random,at last MAX＋PLUS‖is used to test the signal generator and the figure of time sequence simulation is generated.Actual field tests show that the signal generator can fully meet the design requirements,that is it can simulate a variety fire status of automatic weapons.
