摘要
基于对火箭炮发射的复杂动力学进行研究,需要对其发射动力学参数进行采集、分析和处理,而现有的针对火箭发射动力学参数测试的仪器普遍具有体积大、接线复杂、测试距离局限性等缺点。为满足小型便携化、多通道、模块化和不受测试距离限制等要求,采用STM32F407系列芯片作为主控芯片、GSM通信作为上位机与数据采集模块之间的通信方式,同时设计了满足不同物理量需求的信号调理模块,通过软件编程和模块化电路设计,实现对火箭发射动力学参数的采集和分析。
Based on the study of the complex dynamics of rocket launch,it is necessary to collect,analyze and process its launch kinetic parameters.However,the existing instruments for testing the rocket launch dynamics parameters generally have large volume,complicated wiring and limited test distance.Sexual disadvantages.In order to meet the requirements of small portable,multi-channel,modular and untested distance limitation,STM32F407 series chip is used as the main control chip,GSM communication is used as the communication mode between the upper computer and the data acquisition module,and at the same time,it is designed to meet different physical quantities.The signal conditioning module of the demand,through software programming and modular circuit design,achieves the collection and analysis of the rocket launch dynamics parameters.
