一种弹载数据记录器的电源模块设计

摘要

弹载数据记录器电源模块的优劣直接影响信号的采集质量,针对弹载数据记录器在弹射试验中特殊的工作要求,提出了在电源模块中采用可充电锂电池,实现在地弹转电后数据记录器可依靠其自身的电源模块正常工作;为了使锂电池在弹射试验前能够完成充电过程,在地面测试阶段通过长线电源对其供电;该电源模块能够稳定工作3h以上,已成功应用于某弹载数据记录器.%Merits and shortcomings of power supply system directly affects signals, quality to be collected for Bomb - borne Data Recorder. According to its special working requirements, this article proposes a scheme which uses rechargeable lithium battery. It can work normally relying on its power supply module. In order to complete the charging process for lithium battery before launching, the recorder works by long - term power supply. This power supply module can work more than 3 hours stably, and has successfully used in a data recorder.
