摘　　要：设计了基于Direct–Net核心处理模块,支持IPv6通信协议的串口服务器,实现了单点信号控制器基于IPv4或IPv6联网的功能,对智能交通、物联网等领域的发展具有一定的现实意义.实验结果表明,在IPv4和IPv6环境下,上位机客户端均可以通过串口服务器和单点信号控制器通信,实现了现场运行状态远程监视和控制的设计功能.经测试,系统可靠性、稳定性、功能性等各项指标均达到设计要求.The paper designs a serial server based on Direct-Net that supports next generation Internetcommunication protocol named as IPv6 to make single point signal controllers be networked based on IPv4 or IPv6,which has a certain practical significance for the development of intelligent transportation, Internet of Things andother fields. In the IPv4 and IPv6 environment, the PC client can communicate with the single point signal controllerthrough the serial server to achieve the functions of remotely monitoring and controlling running state in the field.After testing, the reliability, stability, functionality and other indicators of system have reached the designrequirements.
