最近几年来,计算机局部网络技术得到了迅速的发展,并逐渐在投入应用。本文针对局部网络的应用现状,综合总线式局部网络的特点,提出了一种优先信息传递的协议,使总线型局部网络能够较好地适应于实时工业控制系统的要求,扩大局部网的应用范围,最后,将信息优先传输服务在具体总线上网络上实现应用。
In recent years, computer local network technology has been rapid development, and gradually put into use. In this paper, according to the status quo of local network and the characteristics of bus local network, a protocol of prioritized information transmission is proposed, which makes the bus local network adapt to the requirements of real-time industrial control system and expand the application range of local network , And finally, the message priority transmission service is implemented on a specific bus network.
