摘要
在混场源电磁接收系统中,为了解决数据采集和处理过程中的大量数据传输的问题,提出用TMS320VC33和通用串行总线(USB)技术相结合实现通讯的方案。对比传统的串口通讯,大大提高了传输速度,为系统实时处理提供了条件。论述了采集系统的整体构成,详细介绍了系统通讯接口的硬件构成和软件实现。测试结果表明该方案可提供较高的数据传输速度,其方便性特别适合应用于地质仪器。
In HSMT system, in order to solve the problem of a large number of data transmission, the communication with USB based on TMS320VC33 is presented. Compared with the traditional serial communication, the speed raises greatly. The whole scheme of data acquisition system is introduced. Then, the hardware structure and software realization are presented. At last, the test result is given. Experiments prove that the method can get good performance especially in geophysics instruments.
