摘　　要：串行接口在工业控制领域得到广泛的应用,而且对串口的功能进行验证具有较为完善的测试设备和方法。另一方面,如何简化并快速进行串口模块的功能验证具有重要的意义。基于此观点,在研究了模块自身的功能特性的基础上,提出一种具有一定通用性的设计思想,即利用通信速率和采样速率之间的关系,将串口收/发送器速率与串口接收器采样速率配置成一定配比关系,从而实现用于测试串口接收器的任意帧结构数据。Serial Communication Interface （SCI） is widely used in the field of industrial control applications. There are complete ways to carry out the verification of the SCI function. It is also important to study brief and fast ways. It is based on this point that the paper has researched the common characters in variety of SCI （or UART）. And it finds the relationship between SCI communication rate and sample rate, and has realized that it can help test SCI function to make SCI RX/TX communication rate and SCI RX sample rate in some relationship to compound any format of SCI data frame.

关 键 词：通信协议 串行通信接口 通信速率 采样速率
