摘　　要：文章主要介绍了采用在线可编程CPU单元和16位串行逐次逼近型A/D芯片,实现8通道电压信号的采集存储与处理功能。解决了早期温箱实验设备不能自动采集温度的问题,确保了卫星产品在测试及环境试验中能够获得精确可靠的实验数据。This paper mainly introduces Data Acquisition Unit based on the In-System Programming CPU unit and 16-bit successive-approximation analog-to-digital converters chip technique. It realizes the functions of collecting, storing and processing the 8-channel voltage signal. Moreover,it resolves the problem that the early temperature box cannot collect tem-perature data automatically during the experiment. The paper also shows that satellite products are able to get accurate and reliable experimental data in environmental tests.
