摘要
文章基于FPGA特性,采用软、硬件协同设计方法,设计了新型火箭橇时序点火控制装置,详细阐述了总体方案设计、按键防抖、火工品在位检测、RS422总线通信及数据存储、读取等主要功能的实现方法,简述了主要IP核的的设计以及仿真试验情况及其在型号中的联试情况。结果表明该新型时序点火控制系统能满足型号和多级火箭橇高可靠性、安全性及通用性试验需求。
A new FPGA-based sequential ignition control device is designed for a rocket sled by adc^ting software and hardware co-design methodology in tibis per, which introduces the overall design scheme aod the realization method of button shake, EED online- detectioii, RS422 bus commimication, data storage and reading etc in detail, also briefly presents the main IP cores design, simulation experiment and tbe test case on the hardware platform. The results show tbat the proposed system can satisfy the test requirements of high reliability, safety and universality.
