摘　　要：针对无人机多传感器矢量磁测补偿系统,研制了一套小体积、低功耗的多通道数据同步采集系统。该系统采用模拟采集和控制部分分开设计的方法。模拟采集部分基于STM32处理器STM32F103C8T6,集成了9通道24位高精度的模数转换芯片ADS1255、倾角和温度传感器,能够实现9通道数据的同步采集、飞行载体的倾角数据和温度数据的获取。控制部分基于32位ARM低功耗处理器S3C2416和嵌入式LINUX系统,完成了数据实时采集、SD卡存储、GNSS同步校时和网络通信等功能,并具有功耗低、体积小的特点,满足了机载数据采集系统特定的应用需求。A multi-channel synchronous data acquisition system with small volume and low power consumption was developed for the UAV multi-sensor vector magnetic measurement compensation system.It adopted a separate design of analog acquisition and control parts,which effectively improved flexibility of installation in limited space.The analog acquisition part was based on STM32 processor STM32F103C8T6,which integrated 9-channel 24-bit high-precision analog-to-digital converter ADS1255,inclination chip and temperature sensor.It can realize synchronous acquisition of 9-channel data,inclination data and temperature data of the carrier.The control part was based on the 32-bit ARM low power processor S3C2416 and embedded LINUX system,and completed the functions of real-time data acquisition,SD card storage,GNSS synchronous time calibration and network communication,and had low power consumption and small size,which can meet the specific application requirements of airborne data acquisition system.
