摘　　要：一种测井数据采集系统,通过IDMA口实现各个DSP之间的数据通信,IDMA接口采用74系列的小规模逻辑电路组成,各个从DSP负责各个通道的数据采集与预处理,主DSP作为各个从DSP之间的桥梁,负责各个从DSP之间的同步、数据传输、程序引导。同时主DSP还是该系统与外围设备之间的接口,确保井上和井下仪器之间正常通信,传输地面设备与井下仪器之间所需的数据。The well logging data acquisition system realizes data communication among every DSP by IDMA interface. The IDMA interface consists of 74 series small-scale logic circuit. The server DSP realizes channel data acquisition and preprocessing. The master DSP is the communication bridge for every server DSP, which realizes the in-phase, data transmission and program inducting among server DSP. At the same time, the master DSP is the interface between system and peripheral equipment to ensure equipment communication among outside and inside of well. Then, the system transmits data between the ground and the inside well equipments.
