摘　　要：针对野外环境下供电方式的特点,提出了一种基于分块间断供电的电源管理方法,以降低遥测终端的耗电量,适应其长期无人值守自动监测的要求。讨论了它的基本结构、工作原理及实现技术,以应用实例说明了其有效性。With a view of power supply mode in open country, a sort of power management means based on discontinuous supply partly is presented in this paper, which can make remote terminal unit to be in permanent self-service. Its framework and principle as well as its implementation are discussed, and its availability is illuminated through actual applications in working fields.
