摘　　要：针对西部和海上油气田开采过程中客观条件的限制,设计了一种两相流计量系统二次仪表,代替计算机进行数据采集和处理,实现在线实时计量。该系统选用DSP作为核心处理器,数据采集采用双缓冲的DMA传输,并利用在系统编程技术和DSP自举引导实现了系统的独立运行。实验证明该仪表具有性能高、功耗低、体积小等优点。A measuring instrument of two phase flow was developed for the western and marine oilfields exploitation, which can realize the data real-time acquisition and disposal instead of computer. The system adopted DSP as the microprocessor, and used two buffers to save the acquired data transmitted by DMA, realized system running independently by using in system programming technology and DSP boot loader. The results show that the instrument has the advantages such as high performance, low power and small size.
