基于DSP的抗辐照控制系统的设计与实现

Design and Implementation of the Anti-Irradiation Control System Based on DSP

抗辐照单片机作为航天用控制系统的核心处理器,常用来实现对动作部件的控制。由于抗辐照单片机功能模块较少,且无法实现多通道开关量的采集与控制、复杂通信等功能,不利于航天用控制系统性能的提升和推广应用。设计了一种基于数字信号处理(Digital Signal Processing,DSP)的抗辐照控制系统,此系统具有丰富的功能模块和通用输入输出接口(General-Purpose Input/Output,GPIO)数量,提升了航天用控制系统的性能,促进其进一步发展。测试结果表明,此控制系统满足性能指标要求,具备较好的航天适用性。

As the core processor of the aerospace control system,the anti-irradiation MCU is commonly used to control the moving components.However,the anti-irradiation MCU has few function modules,and cannot realize the complex communication,the value acquisition,control of multi-channel switching,et al.It is not conducive to improve the performance of the aerospace control system and the application.An anti-irradiation control system based on digital signal processing(DSP)is designed.This system has a wealth of functional modules and general-purpose input/output(GPIO),and improves the performance and the further development of aerospace control systems.The test results show that this control system can meet the performance index requirements and has good aerospace applicability.
