基于51单片机的能源管理系统智能单元的设计

Design of intelligent unit in power manage system based on 51 single-chip microcomputer

临近空间作为不可忽视的资源,其重要的开发应用价值在国际上引起广泛关注。能源供给系统是临近空间飞行器的重要组成分部分。建立智能电源管理系统,实现对电源系统状态的在线监测和数据的实时处理以及能量的有效分配,显得尤为重要。设计了一种基于单片机80C32E的智能电源管理系统,着重介绍了和临近空间环境特点相关的硬件电路设计和软件架构。该系统完成对电源系统重要参数的采集和数据的实时分析、上传,以及蓄电池组的充放电控制等功能。考虑到临近空间飞行器的空间环境对电源系统高可靠度的要求,采用双机冷备份的方式,从而确保了飞行器的能源供给。

As the crucial resource, the important value of near space in exploitation and application brings extensive attention internationally. Power supply system is an important part of aircraft in near space. Accordingly, it is important to establish intelligent power manage system, implement on-line inspecting status of power system and real-time transacting of data. A kind of intelligent power manage system based on single-chip microcomputer 80C32E was designed, and the design of hardware and software in near space environment was introduced. The system could complete collection of the main parameters and real-time analyzing and uploading of data in power system as well as the charging and discharging control. Considering the environment of near space aircraft is strict with power system in reliability, the method of double machine cooling in asynchronous time was adopted to ensure the power supply of aircraft.
