摘　　要：针对某商用返回式卫星回收系统轻小型、高可靠的约束要求,设计了一种新型回收控制器产品,该装置基于微电子机械系统(Micro Electro Mechanical Systems,MEMS)过载传感器进行弹道过载测量,采用双核四进程“与或”逻辑实现冗余控制,基于容性释能半导体桥点火器起爆技术实现火工品管理。策划了针对返回过程的弹道过载触发验证试验,针对容性释能电容阵列放电特性,开展了容性释能系统不同初始电压、不同电容阵列容值以及不同回路阻值下的点火效能仿真分析。结果表明该回收控制器在轻小型约束下返回弹道过载感知精度达到±0.28 g,可实现开伞逻辑高可靠控制。半导体桥点火器容性释能电路优化参数为初始电压大于24 V、回路阻值小于0.3Ω、初始电容大于22μF,可实现点火器高可靠点火控制。该设计在不显著增加硬件基础上,大大降低产品质量,可为航空航天用同类电子系统设计提供参考。In response to the requirements of a lightweight,compact,and highly reliable commercial recoverable satellite recovery system,a recovery controller product based on a MEMS accelerometer for ballistic overload measurement are designed.It incorporates dual-core,four-process“AND-OR”logic for redundant control,and utilizes capacitive discharge semiconductor bridge igniter detonation technology for pyrotechnic device management.The ballistic overload trigger verification tests for the return process are planned.The ignition efficiency simulation analysis of the capacitive energy release system is carried out under different initial voltages,capacitor array capacitance values,and circuit resistance values.The results show that the recovery controller can achieve an overload sensing accuracy of±0.28 g for the return trajectory under the lightweight and compact constraints,and has real-time and highly reliable control of the parachute opening logic.The optimized parameters for the capacitive discharge circuit of the semiconductor bridge igniter comprise an initial voltage greater than 24 V,a circuit resistance less than 0.3Ω,and an initial capacitance greater than 22μF,which can ensure highly reliable ignition control of the igniter.This design can greatly reduce the weight of the product without significantly increasing hardware consumption,and can provide reference for the design of similar electronic systems in aerospace applications.
