基于PROFIBUS-DP协议的计算机联锁控制方案

A Solution for Computer Interlocking Control Based on PROFIBUS-DP

讨论了将PROFIBUS-DP通信技术应用于铁路车站信号计算机联锁系统中,提高计算机联锁系统的智能化、模块化。通过对PROFIBUS-DP现场总线的研究,提出了采用德国赫优讯自动化系统有限公司开发的COMX通信模块在计算机联锁系统中实现PROFIBUS-DP通信协议的方案,应用于现场设备端的DP智能从站的设计和实现,并对设计的智能从站进行了调试,基本实现了与主站的通信。

The paper mainly discussed PROFIBUS-DP communication technology application to the computer interlocking control system of railway station signal, improved computer interlocking system more intelligent and modularization, etc. Through the research of PROFIBUS-DP fieldbus put forward a design proposal by using the COMX eommunication module that invented by the Hilscher GmbH come true the purpose that make use of PROFIBUS - DP in the system of computer interlocking. And rise a method about design and implementation of DP intelligence slave at the side of field device. Then debugging the DP intelligence slave,we can get the result that the slave work well.
