Problems solved by technology

In the system adopting this architecture, the main control unit A only has the control right to the functional units of the A series, and the main control unit B only has the control right to the functional units of the B series. The failed unit also becomes unavailable
At the same time, when there is a faulty unit in the main system and it is switched to the backup system, if a certain unit in the backup system (whether it is symmetrical to the faulty unit in the main system or not) fails, the entire system will be unavailable

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings, and the features of the present invention will be further revealed in the following detailed description.

[0027] figure 2 is a system architecture diagram of an ATO system according to an embodiment of the present invention. exist figure 2 , shows a dual-machine hot standby redundant system, one of which can operate as the main system, and the other can operate as the standby system. However, the present invention is also applicable to redundant systems with more lines, for example, the system contains three or more lines of main control units and functional units, one of which is the main line, and the rest are backup lines. For ease of description, the following descriptions are made using a dual-machine redundant system as an example.

[0028] like figure 2 As shown, the main control unit A, the main control unit B and all functional units are connected thr...

Abstract

The invention provides a cell-level hot standby redundancy ATO system architecture and a cell-level hot standby redundancy automatic train operation system. The system comprises a first sub-system running as a main system, and a second sub-system running as a standby system, wherein the first sub-system is provided with a first main control unit and a first group of functional units; the second sub-system is provided with a second main control unit and a second group of functional units corresponding to the functional units in the first group of functional units one to one; when one function unit in the first group of functional units of the first sub-system breaks down, the system activates the function unit, corresponding to the functional unit which breaks down, in the second group of functional units of the second sub-system, so that the functional units which do not break down in the first sub-system and the activated function unit in the second sub-system continue to work together.

Description

technical field [0001] The invention relates to the field of train operation control systems, in particular to a unit-level hot standby redundant train automatic driving system. Background technique [0002] Automatic Train Operation (ATO for short), its main function is to use on-board and ground information to automatically control train operation, realize automatic adjustment of train speed and keep it in the best running state, complete timing, fixed-point parking, automatic Functions such as door opening and closing control can reduce the labor intensity of the driver and save energy to the greatest extent. [0003] With the development of my country's rail transit industry, ATO has been widely used in urban rail transit, intercity rail transit signaling systems and other fields, and its importance has become increasingly prominent, especially the higher requirements for system safety, reliability and availability . [0004] For system security, ATO is an on-board sign...
