Abstract:: 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.
