[0026] The electronic map module is used to visually locate and navigate the equipment corresponding to the alarm information, and extract the equipment operation information of the equipment. In the electronic map module, the BIM modeling software Revit is used to create a site BIM model, and all equipment is displayed and alarms are presented on the base map of the BIM model. It is associated with the equipment, boards, and ports in the system to achieve physical location and system logical relationship mapping to locate alarms.

Real-time comprehensive analysis of the alarm data and performance data of equipment in the communication system is carried out to achieve the purpose of performance threshold alarm and intelligent anomaly detection. Equipment performance data monitoring is used to achieve long-term supervision and early warning of long-term equipment performance change trends, and to capture equipment change trends in advance and explore laws from a wider dimension.

[0029] The alarm analysis module is used to perform correlation analysis on alarm information. By analyzing the mutual relationship of alarms, the alarm generation order and dependency relationship between multiple alarm information can be obtained. It can provide support for causal relationship and fault location between alarms and accurately locate the fault point. Especially when multiple alarms occur at the same time, the alarm analysis module can be used to find the root cause, eliminate secondary alarm information, and find the root alarm information.

[0030] The method by which the alarm analysis module performs correlation analysis on alarms is as follows: Collect the alarm information of each communication subsystem in urban rail transit and determine the data collection content of each communication subsystem, that is, determine the time when the alarm occurs, the system to which the alarm belongs, and the alarm content.

[0031] Before the alarm occurs, the alarm information within the time threshold is added and merged to obtain the occurrence time of each alarm and the alarm information under the time threshold, and the alarm information under each communication subsystem is marked. In this embodiment, the time threshold is set within the range of 3 minutes to 10 minutes.

[0033] Based on the inspection results, an alarm information network analysis model is constructed.

[0034] Run the alarm information network analysis model to obtain the attribute information of each alarm information in the network and display it visually.

[0035] The method to obtain the attribute information of each alarm information in the network and display it visually is as follows: Generate a network diagram based on the attribute information of each alarm information in the network. The network diagram is as follows: Figure 3 As shown in the figure, the network diagram includes node and edge information, and the node and edge information in the network diagram are analyzed. The node represents each type of alarm, and the number of edges of each node represents the correlation weight of the alarm type. The degree centrality of the node represents the correlation strength between this type of alarm type and other alarm types, and the betweenness centrality of the node reflects the bridge role of this alarm system in connecting with other alarm systems; the weight of each edge in the network diagram represents the degree of correlation between the alarm information connected to the edge; the clustering coefficient in the global network attribute reflects the aggregation of the alarm system, and the network density attribute represents the overall correlation between the alarm information; in the network diagram, the current alarm is the most central node, and the more relevant other alarm information is to the current alarm, the closer it is to the current alarm node in the network diagram and the wider the connection line with the current node.

[0036] The network diagram can be visualized based on the attribute information of network nodes and edges. In the network diagram, the subsystems to which the alarm belongs can be set to different colors. By laying out the network diagram, the categories and associations of different alarm information can be displayed in the diagram. Through network analysis, the alarm information in different subsystems can be integrated into a network diagram, and the redundant data content can be displayed concisely. The association between each alarm information can also be automatically processed based on the time information, which helps to understand the cause of the alarm.

[0037] The equipment history management module is used to record, count and manage equipment history information. The equipment history management module manages equipment history in a unified manner, realizes automatic updating and maintenance of equipment history, and automatically records and counts information such as the board number, software version, number of failures, failure recovery time, and number of replacements of the equipment in use. Based on the theory of full life cycle management, big data technology is used to build a fusion data wide table of equipment assets to realize data concatenation, incremental update and horizontal expansion of equipment operation information. The fusion data wide table organically connects the information of each stage of the equipment to realize the "one-stop" full life cycle management of facility equipment history data.

[0038] The production scheduling module is used to implement equipment maintenance planning and closed-loop management based on the root alarm information, equipment history information, and equipment operation information. Based on the alarm information and equipment operation information, the production scheduling module can start the disposal process, generate maintenance work orders, and push them to the relevant teams.

[0039] In this embodiment, a closed-loop management system for the entire alarm process is provided. According to the alarm prompt or early warning information of the operation monitoring module, the production scheduling module can timely start the handling process, automatically generate a maintenance work order, and push it to the relevant team through the SMS module. The relevant team can view the alarm-related information through the handheld maintenance terminal, and feedback the alarm processing status through the handheld maintenance terminal, close the work order operation, and form a closed-loop management of alarm processing.
