摘　　要：构建可靠的货运列车车内通讯网络是实现货运列车状态在线监测的基础。针对车内无线通讯网络的研究现状,提出了一种混合型货运列车车内通讯网络。该网络利用CAN总线完成单节车辆及机车的内部通讯,并在机车的尾端和车辆两端安装无线模块,可实现同列车的所有机车、车辆之间通讯。通过将有线通讯和无线数据传输相结合,可以显著减小无线通讯距离,提高通讯效率及可靠性。实验表明,该系统可以较好地满足货运列车状态在线监测的通讯功能要求,对于提高货运列车的运行效率和安全性具有重要意义。Building a reliable communication net is the basis of realizing the online monitoring of a freight train status.Aiming at improving the communication net within a freight train,A mixed communication net was proposed.The system was realized by wired and wireless communication combined,using CAN bus for single-vehicle internal communication,and wireless modules installed in both ends of the car to achieve communication between cars.Thereby the distance of the wireless communication was greatly reduced,and the efficiency and reliability of the communication was improved.Experimental results show that the system can meet the communication requirements of the online monitoring in a freight train.
