Problems solved by technology

However, when the communication between the main unit, the backup unit and the switching unit fails and other functions are normal, the switching (management) unit cuts off the output of the main and backup system and exits ATO, or when the communication failure of the switching unit itself will also affect the system function , resulting in the withdrawal of ATO, so the reliability of the existing dual-machine hot standby is low

Embodiment Construction

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0056] Such asfigure 1 As shown, the embodiment of the present invention introduces a dual-system hot-standby switching method applied to the automatic train operation system. The switching method includes, first, the logic unit of the own system and the logic unit of the corresponding system compete for the main and backup sys...

Abstract

The invention discloses a dual-system hot standby switching method and system applied to an automatic train operation system. The switching method comprises the steps that firstly, a system logic unitand an opposite system logic unit are subjected to main standby competition; then, when the system logic unit or the opposite system logic system competes to be the main system, output and communication are controlled, and a main system status signal is output. Due to switching between dual-system hot standby, main and standby system switching is achieved, no back crossing (management) unit or functional similar back crossing (management) unit equipment needs to be added, and the system reliability is improved.

Description

technical field [0001] The invention belongs to the field of rail transit, and in particular relates to a dual-system hot standby switching method and system applied to an automatic train operation system. Background technique [0002] The existing dual-machine hot-standby structure of the automatic train operation system includes a main system, a backup system, a reverse (management) unit, and the like. Therefore, the switching method of dual-machine hot backup is that when the main system fails, the backcut unit cuts off the output of the main system, and the backup system is upgraded to the main system. However, when the communication between the main unit, the backup unit and the switching unit fails and other functions are normal, the switching (management) unit cuts off the output of the main and backup system and exits ATO, or when the communication failure of the switching unit itself will also affect the system function , resulting in withdrawal from ATO, so the re...
