| 摘 要： | 针对某型空中机器人机载电源监测电压存在的温度漂移现象,提出3种温度补偿方案:加入负温度系数热敏电阻、普通光隔线性化、直接采用线性光隔,最终选用高精度线性光隔PS8741;详细给出了PS8741的工作原理及典型应用电路,并对电路进行高低温试验;为便于数据处理,开发了基于MATLAB的图形用户界面(GUI);实验结果表明,利用PS8741测得电压线性度好,抗干扰性强,可有效抑制监测电压随温度漂移,为空中机器人的准确、安全飞行提供有利保障。

| Abstract: | In order to reduce the temperature drift of monitor voltage for a type of aerial robotic airborne power supply,three methods of temperature compensation are presented,high-precision linear optocoupler PS8741 is adopted finally.The operating principle and typical ap- plication circuit are given in detail.The graphical user interface(GUI)based on MATLAB is developed to process data.The high linearity and anti-interference ability of PS8741 are proved by the results of high-low temperature test,the temperature drift of monitor voltage can be reduced markedly.The application of PS8741 can provide adequate protection for aerial robot accurate and safety flight. |
