摘　　要：在发动机寄留释放火箭橇试验中,需同时验证被试发动机静态、动态2种工作状态。为精确控制被试发动机及其他火工品,使其能按预设时间依次工作,设计地面多路时序点火控制系统。详细介绍硬件设计,在此基础上给出主控芯片内部的工作流程及设计方法,并进行试验验证。结果表明:该系统攻克了高精度时序控制、多路大电流驱动输出、多路输出信号间串扰和环境适应性等关键技术,能实现对弹上多种指令和多级火工品的点火控制。During the test of the engine-retained release rocket sled,it is necessary to simultaneously verify 2 working states of the tested engine statically and dynamically.Focusing on how to accurately control the engine and other initiating devices to operate in order according to the pre-set time,this paper designs a ground multichannel timing ignition control system.The hardware design is introduced in detail.Based on this,the internal work flow and design method of the main control chip are given,and the test is verified.The results show that the system breaks through the key technologies of high precision timing control,multi-channel large current drive output,multi-channel output signal crosstalk,and environmental adaptability,etc.This design can achieve ignition control of multiple commands and multi-stage pyrotechnics on the missile.
