基于LabVIEW的串行通信接口设计

Design of Serial Communication Interface Based on LabVIEW

针对传统接口误比特率较高的问题,提出基于LabVIEW的串行通信接口设计研究。运用LabVIEW技术对接收端口进行编程设计,利用鉴相器、压控振荡器、环路滤波器等设备实现时钟信号提取,通过Comma序列设计完成串行数据并行,运用多相时钟法实现串并数据转换,通过相位对齐的设计实现XCLK并行时钟与USJDLK并行时钟的同步,以此完成了基于LabVIEW的串行通信接口设计。经实验证明,该接口具有较低的误比特率,能够良好的满足串行数据的通信。

Interface for traditional high bit error rate problems,study design serial communication interface based on LabVIEW for this propose. Using LabVIEW programming techniques designed receiving port,using a phase detector,a voltage controlled oscillator,loop filter and other equipment to achieve the extracted clock signal,the serial data by the parallel Comma complete sequence was designed,using a multiphase clock and serial data implemented method converting,by phase-aligned with the design and implementation of the parallel clock XCLK USJDLK parallel synchronous clock,thereby completing a serial communication interface based on LabVIEW. The experiment proved that the interface has a lower bit error rate,it is possible to satisfy a good serial data communication.
