Abstract: This paper introduces a supervision software which aims at a type of programmable SCPI command power supply based on LabVIEW，serial communication and a method called“combination of rotating time slice with event trigger” are adopted.The supervision software with friendly interface design and perfect function provides reliable power supply for the flight control computer in the UAV ground half entity simulation trial，which is valuable for other development of measuring and control software.

摘要： 在LabVIEW开发环境下，采用一种“时间片轮转与事件触发相结合“的方法，运用串口通讯设计了针对SCPI命令程控电源的监控软件。该监控软件界面设计友好、功能完善，实现了电源的控制与监测并在无人机半物理仿真试验中完成了飞控计算机电源的稳定供给，对今后的测控软件开发具有重要参考价值。
