摘　　要：针对现有的波特率检测法存在的耗时较长、设计繁琐等问题,提出了基于迭代和修正的波特率自适应算法。该算法以主机波特率为基准,调整各从机的波特率使通信双方波特率一致;各从机分时复用同一总线接口,分别完成与主机波特率的自适应和数据传输。软件仿真和硬件模拟表明:该算法设计简单,精度高,收敛速度快,占用资源少,适用于弹载设备的一对多通信。The present Baud rate detection has disadvantages of much time consuming,cumbersome designing etc.A baud rate self-adapting algorithm based on iteration and correction was put forward in the paper.To take the host baud rate as the benchmark,the algorithm adjusted the baud rate of the slaves so that they could communicate with the same baud rate.By time division multiplexing the same bus interface,the slaves complete baud rate self-adapting and data transmission with the host respectively.Studys showed that the algorithm was of high accuracy,fast convergence and less resource,and suitable for one-to-many communication of missile equipment.
