Embodiment Construction

[0021] 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 are only some 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 belong to the protection scope of the present invention.

[0022] An embodiment of the present invention provides a timing-based intelligent diagnosis method for turnout operation and maintenance of a computer interlocking system. According to the timing sequence of normal switchover, the intelligent diagnosis is divided into two stages: when the switch is switched and after the switch is completed; figure 1 Shown:

[0023] When the turnout is switched, judge whether the auxiliary control relay is invalid;...

Abstract

The invention discloses an intelligent diagnosing method based on timing sequence for computer interlocking system turnout operation and maintenance. Based on analysis of the turnout action process and action timing process, an interface portion and control logic are detected comprehensively by the intelligent diagnosing method, and risk prejudgement and safety protection are effectively carried out to the turnout false action and false expression. Intelligent maintenance of a turnout portion is achieved in the operation and maintenance processes, the false action and false expression are effectively prevented, and safety of a signal system is improved.

Description

technical field [0001] The invention belongs to the field of railway signals, in particular to an intelligent diagnosis method for operation and maintenance of turnouts in a computer interlocking system based on time series. Background technique [0002] The computer interlocking system is a signal device that controls the turnout action, the status of the signal machine, and the status of the section, instructs the driving operation and ensures the safety of the driving operation. Its core function is to handle the receiving and dispatching operations. To handle the receiving and dispatching operation, the turning of the turnout must be completed first. After the turning of the turnout is in place, the approach is locked and the signal can be opened. The signal instructs the train to run according to the prescribed speed and traffic permit. Among them, the path connected by the turnout to the fork road is the premise of the operation of receiving and dispatching trains from...
