串行总线信号采集与译码方法研究

The Acquisition and Coding of Serial Impulse Based on LabVIEW

某型武器系统与其火控系统采用串行总线通讯,为掌握向该武器系统装定数据的内容,需要对串行总线信号进行采集与译码。本文设计了一种基于PXI总线的数据采集系统,它以LabVIEW为软件编程平台,采用高速I/O采集卡同步触发模式完成数据采集,较好地解决了串行总线信号采集过程中易出现的数据丢失、存储溢出等问题,经现场测试,该套系统运行稳定可靠,结果准确,达到了预期的效果。

The certain type of weapon system use Serial Bus to communicate with its fire control system. To master the data transmitted to the system,the acquisition and coding of serial impulse signal is very important. This paper designs an signal acquisition system based on PXI bus. Combining the advanced data acquisition technique based on PXI bus,the system uses LabVIEW as its software platform. It makes up the defect of huge data number and coding complexity when the signal acquisition system before is used on the system. The experimental results demonstrate the good data acquisition and coding capability of the system.
