Embodiment Construction

[0019] The invention aims at the characteristics of information transmission of the train control system, and optimizes the wireless transmission mode in the data communication subsystem. For the instructions issued by the regional control center to the on-board controller, as well as the safety control data related to the train position, speed, running direction and status of the on-board controller sent back by the on-board controller to the regional control center, ensure that it is in the wireless network Priority transmission.

[0020] According to the logical structure of the wireless train control system, the present invention assigns the IP address of the same subnet (non-safe IP subnet) to the management layer equipment, and assigns the IP address (non-safe IP subnet) of the same subnet to the equipment of the operation layer and the execution layer (including regional control equipment, trackside control equipment and vehicle-mounted equipment) control device) to ass...

Abstract

The invention discloses a method for applying wireless priority based on an IP (internet protocol) address in a train control system. The method is characterized in that a sub-network and a corresponding IP address are distributed to wireless train control system equipment; safety equipment is considered as a safety sub-network, and a non-safety equipment is considered as a non-safety sub-network; and the data of the safety sub-network is preferentially transmitted through a wireless channel. With the adoption of the method disclosed by the invention, the wireless transmission mode in the data communication subsystem is optimized based on the property of the information transmission of the train control system.

Description

technical field [0001] The invention belongs to the field of train control, and is mainly used for determining the priority of data information in a train control system according to IP address division, so as to ensure the priority real-time transmission of safety control information. Background technique [0002] With the development of informatization, the tentacles of communication technology and computer technology have extended to every corner of social life. The automation and informatization leap in any field is inseparable from the support of these technologies, and the field of train signal control is no exception. The communication-based train control system (CBTC) controls trains through continuous, two-way train-to-ground communication, thereby greatly improving train safety and system transportation efficiency. At present, CBTC technology has also become the mainstream technology of train control system. [0003] The CBTC system in which the vehicle-to-ground...
