dsPIC在阵列声波测井仪采集系统中的应用

The Application of dsPIC in the Array Sonic Logging Acquisition System

介绍了dsPIC在阵列声波测井仪采集系统中的应用设计方案。采用dsPIC实现对采集系统的控制、采集、存储以及数据处理。介绍了该系统的分布式处理思想,每个通道数据由独立的dsPIC进行处理。同时使用1个dsPIC进行数据汇总和协调各个dsPIC模块的工作。详细阐述了该采集系统的系统结构、A/D转换电路以及采集系统与主dsPIC的通信接口,并介绍了数据采集和数据处理的过程。

Design of the array sonic acquisition system with dsPIC is introduced in the paper. dsPIC is used in the data acquisition system to realize system control, data acquisition, data saving and processing. The idea of distributed processing that the data of every channel is processed by dsPIC independently is also introduced, and a main dsPIC is used to collect the data and coordinate each dsPIC module simultaneously. The structure of the acquisition system, the A/D circuit and the interface between the acquisition system and the main dsPIC are introduced in detail.
