摘要 介绍了一种新型微型飞行器高度计的研制技术.利用微型数字压力传感器和数字信号处理(DSP)串口通迅,读取数字压力传感器中压力、温度值及补偿参数,用软件进行温度补偿和高度计算.介绍了在2种温度、2种压力下校正传感器的灵敏度、零漂等参数的方法及温度补偿原理.实验室测试表明:该高度计的误差小于±5 m,分辨率为1 m.经飞行试验,证实所研制的高度计具有体积小,重量轻,功耗低,精度高,工作可靠等特点. A kind of new technology of altimeter of micro air vehicle (MAV) is introduced. Based on the digital signal process (DSP) communication with digital pressure sensor, the pressure, temperature and cali bration coefficients can be read from digital pressure sensor. The temperature compensation and height calculation are conducted using software. The paper mainly introduces the method that calibrates the sensor's sensitivity and offset and temperature compensation. The laboratory test results show that the error of altimeter is less than 5 m. The flight experiment shows that the altimeter has many merits such as small volume, light weight, low power consumption, and high precision, and high reliability etc.
