Circuit characterized in that ATP and LKJ achieve non-stop automatic switching of control power and train

Abstract

The embodiment of the invention discloses a circuit characterized in that an ATP and an LKJ achieve non-stop automatic switching of the control power and a train. The circuit comprises a first switchmodule and a second switch module. The second switch module is controlled by the ATP. When the third input end and the second output end are connected by the second switch module, the first switch module is directly controlled by the ATP so that switching of the ATP and the LKJ can be achieved. When the ATP has a fault, the fourth input end and the second output end can be directly connected by the first switch module, and the train is controlled by the LKJ. The control of the ATP over the second switch module is conducted in the process that the train runs in the switching region, and the purpose that switching of train-mounted train control systems is conducted under the condition that the train does not stop is achieved. Compared with manual switching of the train-mounted train controlsystems, the circuit has the advantages that the switching efficiency is improved, and the transport efficiency of the train is guaranteed.

Description

technical field

[0001] The embodiment of the present invention relates to the technical field of switching control systems on trains, in particular to a circuit and a train for automatically switching control rights between ATP and LKJ without stopping. Background technique

[0002] The section signal of the existing heavy-duty railway line adopts three-display automatic block or four-display automatic block, and the on-board vehicle control system is LKJ system. However, in the process of heavy-duty mobile block reconstruction, there are some lines in the reconstruction line that are automatically blocked by the original three-display or four-display, and some lines are transformed into mobile block. The original LKJ system compatible with three-display or four-display auto-blocking. The vehicle-mounted ATP of the mobile block system and the existing LKJ system will control the locomotive at different times, and the dual system will face problems such as control switching....
