Description
Technical Field
The application relates to the technical field of intelligent operation and maintenance of urban rail transit, in particular to a rail transit signal equipment fault processing method, device and system.
Background
The urban rail transit signal system is key technical equipment for ensuring normal operation of a train. In the daily operation process, once a signal device fails, the degradation control of a signal system is often caused, and even the normal operation is interrupted. Therefore, in order to quickly locate a specific fault point and take scientific and reasonable measures to repair the fault when the equipment has a fault, the availability design index of the signal system requires that the fault can be located to an online Replaceable Unit (LRU) after the fault occurs, but for more complex faults which affect each other between the equipment, the system is often difficult to give an accurate judgment and processing scheme. In the aspect of field maintenance, a first-line maintainer in charge of daily maintenance work of the signal equipment is required to have firm service capability, abundant first-line equipment maintenance experience, skillful skill level and good psychological quality, and when a fault occurs, the fault position can be quickly judged, the fault can be eliminated in a short time as much as possible, and the system function and the normal driving order can be restored. Meanwhile, the operation and maintenance department, the professional shift and the multiple professions need to have higher cooperative working capacity and uniform resource allocation capacity. However, in the maintenance work of the actual signal equipment, because the signal system is large and complex, the fault is often not easily and quickly located to a specific LRU by manual experience. In addition, in the process of analyzing and judging the fault position and taking fault handling measures, the experience of field personnel and the summary of the conventional fault handling measures are relied more, and intelligent information support and detailed paperless record of the whole process are lacked. In addition, when a fault is responded, resources such as available communication equipment, spare parts, tools, manpower, drawings and the like need to be manually and synchronously allocated on site according to a fault responding scheme, so that time and labor are wasted, and mistakes are easily made in busy hours. After the fault is disposed, the whole processing process needs to be summarized in detail, and the analysis is insufficient, the learning experience and the training are needed. The whole process lacks systematic and automatic auxiliary maintenance equipment.
At present, in most urban rail transit lines, maintenance work of signal equipment is basically completed by a large number of operation and maintenance engineers in the same line and experienced technologies, fault analysis and processing are completely completed by experience and judgment of correctness at the first time, and resource allocation is also completely completed by manpower. The operation and maintenance work of the signal equipment is faced with the problems of serious dependence on manual experience, lack of automatic auxiliary technical means, high manpower and management cost, high guarantee difficulty, incomplete information loss, incapability of digitalizing and instantiating maintenance experience and knowledge and the like. Therefore, an intelligent maintenance auxiliary system is urgently needed, when a signal device fails, the system can automatically analyze and judge the position and the characteristics of the fault, automatically generate a maintenance scheme, automatically allocate various resources, record the whole maintenance processing process and make experience knowledge.

And the fault positioning module is used for analyzing the position of the fault and primarily locking the fault equipment. The module is pre-stored with a whole Line signal system architecture and an interface relationship, and is refined to each LRU (Line Replaceable Unit) function and the cooperative relationship between the interfaces and the whole. When the system monitors fault alarm information, the system screens out possible associated equipment of the fault by analyzing characteristic information such as time, source, grade, fault code and the like of the alarm information so as to lock a local range where the fault is located, give a possible position of a fault point and provide an analysis result to a fault comprehensive analysis module.
