Embodiment Construction

[0059]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0060] refer to image 3 , introduces the architecture of the redundant signal control system of the present invention. The front and rear of the train are respectively equipped with a set of independent on-board signal control system VOBC (VOBC), including speed measuring equipment, beacon antenna and processing unit. VOBCs at both ends are connected through redundant red and blue networks.

[0061] refer to Figure 4 , positioning synchronization flow c...

Abstract

The invention relates to a train positioning synchronization method and device, equipment and a storage medium. The train positioning synchronization method comprises the following steps: 101 calculating an original positioning LocalOrigLoc of a local end; 102 receiving remote end original positioning and time information RemoteOrigLoc; 103 calculating a secure transmission delay TransTime from the remote end VOBC to the local end VOBC; 104 calculating the positioning RemoteEstiLoc of the remote end at the current moment; and 105 carrying out train positioning, and taking an intersection of the LocalOrigLoc and the RemoteEstiLoc. Compared with the prior art, the method has the advantages that the safety positioning precision is improved, the train tracking interval is shortened, and the signal system equipment cost is reduced.

Description

technical field [0001] The invention relates to a train signal control system, in particular to a train positioning synchronization method, device, equipment and storage medium for the train signal control system. Background technique [0002] Train positioning is the core function of urban rail transit on-board signaling system (hereinafter referred to as VOBC), and is the basis for realizing train safety protection and automatic driving. During the movement of the train, VOBC receives the information of the transponder arranged on the track through the on-board transponder antenna, so as to obtain the initial positioning of the train. The real-time positioning of the train is updated according to the speed measuring equipment. Train positioning is updated by calibration of transponders spaced at unequal intervals. [0003] The safe positioning of the train should consider the measurement error of the speed measuring equipment to ensure that the safe envelope of the train...
