激光自准直经纬仪电源监控系统设计

为了保证激光自准直经纬仪在野外环境下,能够长时间正常工作,设计了一套便携式的供电电源及其监控系统,主要由锂电池组、DC/DC模块、充放电控制模块、显示告警模块等部分组成,输出激光自准直经纬仪需要的直流电源,显示供电电源的电量,并且当电池电量达到最低限时能够告警并自动充电。实验结果表明,连续供电时间超过20h,携带方便、操作简单,满足了用户的使用要求。

Design of power supply monitoring system in laser autocollimator theodolite

In order to ensure the long time work of laser autocollimator theodolite in the wild environment,the portable power supply and monitoring system has been designed.The system is composed of lithium battery pile,DC/DC module,charge and discharge controlling module,display and warning module.It provides the power supply,shows the power supply quantity,and can warn and charge automatically when battery power achieves minimum.Experimental results show that the continuous power supply time exceed 20 h,it's easy t...
