In order to monitor the state of UAV power system and increase its safety, a design of UAV power management system is introduced, utilizing the abundant interface of mega161. According to the information of supply power and auxiliary power, which is collected by AVR, and the command information from the ground station, the system could charge these batteries intellectually. This system could transmit the data collected by AVR to the ground station and receive the control command from the station, utilizing the transceiver's (XT09- SI) quality of long distance and high security. Experiments showed that this system could complete the task automatically, and transmit the information of UAV power and control information between transceiver and ground station, guaranteeing the safety of the helicopter.%为了能实时监控无人机电源系统的状态和提高无人机的安全可靠性,利用Atmegal61丰富的资源和接口,设计了一套无人机电源管理系统;该系统通过单片机采集供电电源和备用电源的电压,根据这些数据以及地面站的控制命令,对两组电源进行充放电管理;该系统采用了无线射频模块XT09-SI,利用其长距离特性及高级网络安全等特点,将单片机采集到的电源信息发送给地面站,并接收地面监控平台发送过来的允放电等控制命令.实验结果表明该系统能自主完成机载电源的充放电管理,快速准确的传输飞机的电源、控制等信息,能够保障自主飞行时无人直升机的安全.
