Abstract本文介绍了星载电场仪上的数据采集和传输系统设计。该系统以C8051F020单片机为核心控制芯片,控制外围CAN控制器和多路A/D转换器,实现了模拟量和数字量的采集和传输;此外,针对模拟信号动态范围较大的问题,实现了对信号进行可变增益放大的控制。文章阐述了系统的硬件设计和软件设计,并给出了测试的结果。测试结果表明,该系统功能完善,运行稳定。
Other AbstractThis paper introduces the data acquisition,transmission and constant current source design for a satellite onboard electric field meter.It takes C8051F020 as a central processing chip which controls CAN bus controller,multi-channel A/D converting to implement data acquisition and transmission.This paper describes the hardware and software design,and lists the test result.Test result shows that the system has a complete function and works stably.
