基于dsPIC的存储式数据采集系统设计与实现

Design and Implementation of Storable Data Acquisition System Based on dsPIC

文章介绍的存储式数据采集系统应用于随钻声波测井仪中,它以dsPIC芯片做为控制核心,利用时钟芯片(RTC)实现了随钻声波测井仪器的定时启动工作,具有高速数据采集、大容量数据存储、高速数据传输等功能。实验结果表明,以dsPIC为核心的存储式数据采集系统能够满足随钻声波测井仪在控制和数据处理方面的要求。

This paper introduces the storable data acquisition system which is used in acoustic Logging While Drilling（LWD） tool. The dsPIC chip is used as the core of the acoustic LWD tool, which realized acoustic timing transmitter, high speed data acquisition, high -capacity data storage,high speed data transmission etc. The test results show that the system of storable data acquisition based on dsPIC can meet the requirements of control and data processing in acoustic LWD tool.
