Problems solved by technology

The confirmation of faults is mainly done manually. Maintenance personnel need to check the maintenance workstations of each subsystem of the signal separately and combine the actual status of the equipment to confirm the fault and report it to the dispatcher by phone, resulting in low efficiency of fault judgment

Embodiment Construction

[0034] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] figure 2 It is a flow chart of the subway signal fault early warning method of an embodiment of the present invention; figure 2 , the early warning method includes the following steps:

[0036] S1: Real-time collection of working status parameters of each device on the current subway line;

[0037] S2: Judging whether each device on the current subway line is normal according to the collected working state parameters, if not, generating alarm information, and analyzing the alarm information to generate fault information corresponding to the fault; if If all the devices on the current subway line are normal, then directly return to step S1.

[0038] In the exis...

Abstract

The invention discloses an early warning method and an early warning system of subway signal faults and relate to rail transit technical field. The early warning method comprises: S1: acquiring the operating state parameters of various devices of a current subway line in real time; and S2: determining whether the various devices of the subway line are normal according to the operating state parameters, and if not, generating alarm information and analyzing the same in order to generate fault information corresponding to a fault. The early warning method and the early warning system acquire the operating state parameters of various devices of the current subway line and perform determination according to the operating state parameters so as to achieve automatic fault detection and increase fault determining efficiency, and may inquire a processing prepared plan database in order to obtain a processing prepared plan corresponding to the fault information, thereby increasing fault determining speed. The early warning system may immediately publish urban rail transit signal fault information and trip references to Internet such that passengers may automatically obtain the fault information and transfer suggestion with a mobile terminal connected with Internet.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a subway signal failure early warning method and system. Background technique [0002] Urban rail transit signal control system is the core system of rail transit to control the operation of trains and ensure the safety and efficient operation of trains. The failure of the signal system is closely related to the operation, and will directly affect the safe driving and passenger travel. When the signal system fails, it may cause station closures, reduce operational efficiency, and even cause large-scale outages, which may seriously affect the traffic conditions of the entire city. influences. [0003] like figure 1 As shown, at present, the maintenance personnel of various lines in the city confirm the fault by checking the maintenance terminals of each subsystem of the signal and combining the situation of the field equipment, and report the fault to the dispatcher of the ...
