摘 要: | 为满足建立动态易调整串行通信网络的需求,采用基于盲环境下对通讯波特率和帧格式自动识别的方法,设计了一种智能串行通信终端。在完成对上位机的通信设置后,该终端可在一切未知条件下自动识别并跟随上位机的通信设置,与上位机建立通信。工业应用证明该方法设计的智能串行通信终端运行稳定可靠、抗扰性能好、可大大提高串行通信的灵活性。

Abstract: | To meet the needs of establishing a dynamic adjustable serial communication network, an intelligent serial communication terminal is designed using the method of automatic identification of communication baud rate and frame format in blind environment. After communication settings of host computer, the terminal can automatically identify and follow the communication setting of host computer and establish communication with host computer. Industrial application has proved that the intelligent serial communication terminal designed by this method enhances greatly the flexibility of serial communication with its stable and reliable operation and interference rejection. |
