System and method for controlling train topology equipment based on LTE

Abstract

The invention provides a system for controlling train topology equipment based on LTE. The system is characterized in that the system comprises a control center, a server, ETBN equipment and equipmentE which is based on the ETBN equipment and comprises an APN encryption module and an LTE communication module. The control center interacts with the server, the equipment E is arranged in one carriage of the train, the ETBN equipment is arranged in the other carriages of the train, and the equipment E and the ETBN equipment interact with the server; and the equipment E interacts with ETBN equipment, the equipment E acquires IP addresses of the equipment E and the ETBN equipment after establishing connection with a server, and the ETBN equipment and the equipment E are in 4G network connectionwith the server. According to the invention, the system can adapt to more use environments.

Description

technical field [0001] The invention belongs to the application field of EMU communication, and in particular relates to the technology of controlling train topology equipment based on LTE. Background technique [0002] With the rapid development of train network technology, the development trend of Ethernet technology applied to train network gradually emerges. In order to respond to the needs of train operation, the train will adjust the length of the train according to the passenger load to achieve the purpose of flexible use and improve operating efficiency. In order to realize the interconnection and intercommunication of Ethernet networks among flexible groups, the IEC61375 series of international standards has released a series of related technical standards on train Ethernet. important standards in the field. The popularization of the network in the 4G era has provided new opportunities for the management of train network equipment. The equipment of the train topol...

Problems solved by technology

The popularization of the network in the 4G era has provided new opportunities for the management of train network equipment. The equipment of the train topology network has realized diversification and networking. Based on the IES61375 series standards, the existing train topology mainly realizes the realization of the reorganization network between the marshalling cars. The equipment in the train is managed and maintained by the train control room. If you need to remotely manage and view equipment information, you must go to the train or have the on-site inspection by the train personnel, resulting in high management costs and low management efficiency. Manage data security and ease of access

Although this comparative document 1 is based on the LTE network for wireless transmission of data, this comparative document 1 is specifically a method in which the data of the train communication bus is CAN or 485 bus is converted into a network message and transmitted to the server through the LTE network, The train equipment needs to support CAN or 485 bus, but many scene devices only support network communication, it should be that the comparison document 1 is not applicable in many scenes
