摘　　要：针对工业控制领域中对多串口通信的需求,采用SOPC技术并利用FPGA的可编程性,给出了一个基于Nios Ⅱ的30路串口数据转发通信处理机的设计方法,同时定义了相应的数据通信协议,从而实现了30路下位机与上位机的串口通信。实验结果表明,该系统具有相对较高的可靠性和稳定性,并可以根据实际需求灵活改变串口个数,具有良好的可移植性、易实现性和灵活性。In the field of industrial control serial communication needs, using SOPC technology and use of FPGA＇s program mability, gives a Nios Ⅱ-based 30-way serial data communication processor design forward, and it defines the corresponding Data communication protocol, down the road in order to achieve a 30 bit machine with the host computer＇s serial port communications. Experimental results show that the system has relatively high reliability and stability, and flexibility to change according to the serial number of the actual demand, with good portability, easy to implement and flexibility.
