A Design of low - cost uncontrolled rocket ignition timing controller

摘要:

本文基于无控火箭，设计了一种低成本多路点火时序控制器。系统以STM8为控制器，采用震动开关完成火箭计时零点的采集，按照既定流程，完成火箭的时序控制。系统设计火工品运输及发射，因此设计了一套完整的电路与软件流程，完成火工品安全保护、火箭时序装订，火工品阻值检测、时序控制器自检及上报、过载检测，火工品点火，故障上报及处理等功能，系统在地面的自检率为85%以上。试验结果表明，控制器可以在-20℃至50℃工作，可应用于增雨防雹火箭、探空火箭以及模拟训练火箭等领域，用户可以根据不同的火箭发动机选择过载检测时间，根据点火头引爆参数，选择不同的容值的电路参数，根据不同流程，装订不同的时序，完成精确的无控火箭时序控制。

Abstract:

In this paper, a low - cost multi - ignition timing controller is designed based on non - controlled rocket. This system usess STM8 as the main control board, adopts the vibration switch to complete the acquisition of the time zero of the rocket, and completes the timing control of the rocket according to the established process.The system is designed for the transportation and launch of pyrotechnics, so a complete set of circuit and software flow is designed to complete such functions as pyrotechnics safety protection, rocket timing binding, pyrotechnics resistance value detection, timing controller self-inspection and reporting, overload detection, pyrotechnics ignition, fault reporting and handling.The test results show that the control er can work in - 20 ℃ to 50 ℃, adding that one can be applied to prevent hail rockets, sounding rockets, as well as simulation training in areas such as rocket, the user can choose according to different rocket motor overload detection time, according to the ignition head detonation parameters, choose different capacitance value of capacitance, according to the different process, different temporal binding, complete accurate control rocket sequential control.
