摘要
为满足声波测井中大量声波数据的传输需求,提出了基于DMA方式的声波数据传输方案。针对原有声波测井系统中不具有总线让出功能的微控制器,该方案使用USB接口芯片、可编程逻辑器件和先入先出存储器,实现了声波数据的DMA方式传输,并且在应用层具有出错重传的功能。通过仿真和整体系统测试验证了该方案的可行性,满足了测井中大量声波数据的传输要求。
To transfer bulk of acoustic data in acoustic logging system, acoustic data transmission scheme based on DMA was provided. For Microcontrollers in previous logging system that can＇t be bus-off, implements data transmission by DMA using USB interface chip, programmable logic device and first-in-first-out memory, and also can retransfer data on finding error in application layer. The scheme is feasible by using simulation and system test, and meets the need of bulk of acoustic data transmission.
