Problems solved by technology

Due to the inherent characteristics of this open structure, a certain RE may receive control commands from multiple VOBCs at the same time. If it is not handled properly, it may cause the state of the RE to change during the process of a certain RE being controlled and used by a certain VOBC. The problem of being controlled and changed by other VOBCs may cause serious accidents of car crashes and fatalities. Therefore, it is necessary to deal with the competition and sharing of RE resources among multiple VOBCs
However, there is still no mature and open solution for how to solve this problem, especially to increase the sharing requirements of multiple VOBCs for the same RE resources as much as possible on the basis of ensuring safety

Abstract

The invention provides a method for a safety control trackside device of a vehicle-mounted controller. The method comprises the following steps: after a train enters into an access road, acquiring a trackside controller corresponding to the access road by the vehicle-mounted controller according to an access table; sending a request for applying for a control right of the trackside device in the access road by the trackside controller; returning the control right of the trackside device to the vehicle-mounted controller by the trackside controller; operating the trackside device in the access road by the vehicle-mounted controller through the trackside controller; after completing the operation, returning the control right of the trackside device to the trackside controller by the vehicle-mounted controller. According to the invention, a control right mechanism is designed for realizing the cooperative control of the vehicle-mounted controller and the trackside controller; the safety in controlling the trackside device by the vehicle-mounted controller is guaranteed; the trackside device can be used when the expected states of a plurality of vehicle-mounted controllers for the trackside device are consistent to each other; the system efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of rail traffic safety control, in particular to a method for a vehicle-mounted controller to safely control trackside equipment. Background technique [0002] With the development of my country's national economy and the acceleration of urbanization, urban traffic congestion and traffic connection problems between large, medium and small cities and small towns are becoming more and more serious. As an important means of relieving traffic pressure, the pace of development of rail transit is accelerating. , the demand for urban rail transit and intercity railway construction is becoming stronger and stronger. [0003] As the "brain and nerve center" of rail transit, the development pressure of train operation control technology is increasing day by day. Communication-based CBTC (Communication Based Train Control System, train operation control system) has played a huge role in the construction of urban rail t...
