1.本文指出触发引信是控制弹丸(或火箭战斗部)主装药的状态与转换的自动控制系统。按其功能、结构与作用特点,它是混合(模拟～逻辑)时序系统或有限状态机。并给出应用布尔代数和阈函数建立触发引信系统数学模型的方法。2.讨论了触发引信处理信息的特点,并指出其识别信息的功能。3.对触发引信时序系统模型的应用提出探讨性的看法。 1. This paper points out that the triggering fuze is an automatic control system that controls the state and transition of the projectile (or rocket warhead) main charge. According to its function, structure and function characteristics, it is a hybrid (analog ~ logic) timing system or finite state machine. The method of establishing the mathematical model of triggering fuze system by using Boolean algebra and threshold function is given. The characteristics of trigger fuze handling information are discussed and the function of identifying information is pointed out. Propose a tentative view on the application of triggering fuze timing system model.
