[0024] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0025] like Figure 1 As shown, the rail transit equipment fault rapid handling method comprises the following steps:

[0026] Step S1: Sort out the relationship between the equipment points of the integrated monitoring system (ISCS) and the equipment ledger managed by the equipment operation and maintenance system (MMS). ISCS usually takes different points on the equipment as management objects, which is convenient for refined alarm monitoring; while MMS usually defines a single device as a management object, which is convenient for daily inspections, repairs and maintenance; therefore, MMS and ISCS are usually a one-to-n relationship, that is, one device contains multiple monitoring points.

[0027] Step S2: Based on the sorted relationships, an intermediate mapping relationship is established to integrate the point attributes of the ISCS system monitoring dimension with the equipment attributes of the MMS system daily operation and maintenance management dimension to achieve underlying data model matching. When the equipment point alarm occurs, the system can clearly locate the faulty equipment and describe the fault phenomenon to ensure the accuracy and effectiveness of data flow.

[0028] like Figure 2 As shown in the figure, taking the No. 1 sliding door of the up platform of the subway station as an example, the comprehensive monitoring points include manual and automatic status, door closing and locking, DCU failure, motor failure, door opening encountering resistance 3 times, etc. For equipment operation and maintenance management, the No. 1 sliding door is taken as the management object for maintenance work, so it is necessary to sort out and establish a one-to-n mapping relationship.

[0029] The mapping table uses the equipment point label as the primary key to uniquely identify the alarm point. The ISCS point label can be automatically associated with the MMS system equipment ledger. The ISCS field model includes: line, specialty, system, equipment label, equipment name, location, precise location, etc.; the MMS system includes fields such as line, specialty, equipment code, equipment name, equipment alias, equipment classification, installation area, etc. For example, after the ISCS dig.tyz.sxzthdm1.dcugz point alarm, the mapping relationship is used to quickly retrieve and match the No. 1 sliding door of the uplink platform coded as 0201030001 in the MMS system to achieve the transmission and interoperability of the underlying data, as shown in Table 1.

[0031]

[0032]

[0033] Step S3: Establish an association between equipment failure and fault handling process, match different fault handling processes according to the importance of the equipment and the fault impact level. The fault handling process includes ordinary handling process and emergency handling process. When important equipment failure endangers driving or operational safety, such as the sliding door cannot be closed, the emergency handling process is automatically started; when an ordinary equipment failure alarm occurs, it is quickly handled according to the ordinary handling process.

[0034] Step S4: Establish the relationship between equipment failure, management profession and maintenance operation template. According to the ownership relationship of equipment management, determine which profession is responsible for the management of each operating equipment when a failure occurs, and automatically match the corresponding maintenance operation template. The management professions of comprehensive monitoring equipment in subway stations include electromechanical, door and ladder, automation, AFC and other professions. The electromechanical profession is further divided into environmental control, water supply and drainage, low-voltage power distribution and other minor professions. In order to clarify the automatic matching of maintenance operations with accurate management professions, a management affiliation model of management profession classification and equipment classification is established through the parent-child nodes of the tree structure, for example:

[0035] {"F_CODE":"01","F_NAME":"Station Management","F_PARENT_CODE":"","F_PARENT_NAME":"",F_LV:1},{"F_CODE":"0101","F_NAME":"Mechanical and Electrical Engineering","F_PARENT_CODE":"01","F_PARENT_NAME":"Station Management",F_LV:2},{"F_CODE":"010103","F_NAME":"Low Voltage Power Distribution", "F_PARENT_CODE":"0101","F_PARENT_NAME":"Mechanical and electrical engineering",F_LV:3},{"F_CODE":"01010303","F_NAME":"Lighting distribution box","F_PARENT_CODE":"010103","F_PARENT_NAME":"Low voltage power distribution",F_LV:4},{"F_CODE":"0101030301","F_NAME":"Lighting distribution box 01","F_PARE NT_CODE":"01010303","F_PARENT_NAME":"Lighting distribution box",F_LV:5}。

[0036] When a specific device (Lv5) fails, it will automatically match which equipment category (Lv4) the device belongs to, and then further determine the minor (Lv3) and major (Lv2) that manage the device, and finally determine which station (Lv1) will manage it, so as to establish the association between equipment maintenance operations and management professions, as shown in Table 2 below.

[0037] Table 2 Classification of professional management of equipment

[0038] Lv1 Lv2 Lv3 Lv4 Lv5 Station Management Mechanical and Electrical Engineering Environmental Control Water supply and drainage Low voltage power distribution Ventilation and air conditioning electric control cabinet Power distribution box Lighting distribution box Lighting distribution box 01 Lighting distribution box 02 ... Door and ladder professional Automation ...

[0039] According to different management professional contents, the corresponding maintenance work order template is automatically matched. When an alarm occurs at the equipment monitoring point, the fault point information, fault time, fault location, fault phenomenon and other information are transmitted from the ISCS system to the MMS system through the establishment of a standard REST transmission protocol; the MMS system parses and converts the incoming JSON data through the monitoring point and equipment mapping relationship established in step S2; finally, the work order template class Map is used in the system background<string,Object> This information is automatically captured and filled into the corresponding maintenance work order. After the maintenance personnel receive the order, they can arrange the corresponding preparation work in advance based on the details of the equipment failure.

[0040] Step S5: According to the equipment management specialty specified in step S4, the team shifts and shift handover personnel information of the specialty for the day are determined, and combined with OA attendance and handheld terminal positioning for analysis, the current on-duty and nearest on-duty personnel are determined. After a series of screening strategies, the maintenance work order is automatically assigned to the team member most suitable for on-site maintenance.

[0041] According to the equipment management specialty specified in step S4, all teams under the management specialty are retrieved, and the data structure is as follows:

[0042] {"F_MAJOR":"010103","F_TEAMS":[{"F_TEAM_ID":"010103yb","F_TEAM_NAME":"Low Voltage Distribution Class B"}]}.

[0043] The subway maintenance team generally follows the "day and night rest" shift rule to change shifts. The current shift changeover team is determined using the shift changeover rule. The data structure is as follows:

[0044] {"F_MAJOR":010103","F_GIVE_TEAM_ID":"010103jb","F_GIVE_TEAM_NAME":"Low Voltage Distribution Class A","F_GIVE_TEAM_MEMBER":[{"F_PERSON_ID":"4600013","F_PERSO N_NAME":"Maintenance Personnel A"},{"F_PERSON_ID":"4600054","F_PERSON_NAME":"Maintenance Personnel B"}],"F_RECEIVE_TEAM_ID":"010103yb","F_RECEIVE_TEAM_NAME":"Low Voltage Distribution Class B","F_RECEIVE_TEAM_MEMBER":[{"F_PERSON_ID":"4600027","F_PERSON_NAME":"Maintenance Personnel B"}] E":"Maintenance Personnel C"},{"F_PERSON_ID":"4600042","F_PERSON_NAME":"Maintenance Personnel D"}]}.

[0045] According to the OA attendance punch-in information and the F_PERSON_ID of the team members, all the team members on duty in the current profession are screened. Combined with the handheld terminal positioning function, the location information of the on-duty personnel and the fault location are obtained in real time for spatial distance analysis, so as to determine the person closest to the fault point.

[0046] Step S6: Maintenance personnel receive maintenance work orders for equipment failure alarms under this management profession, plan routes in advance, and prepare maintenance tools and other materials for on-site disposal. Finally, when an alarm is triggered at an equipment point under comprehensive monitoring, the system automatically starts the most suitable disposal process after analysis and judgment, and pushes the fault information to the most suitable team member on site with the most suitable operation template. The entire fault handling link automatically matches fast options, reduces the time for manual judgment and coordination in the middle links, enhances the response speed of fault handling, and ensures operational safety. The complete rail transit equipment fault rapid disposal data model relationship diagram is shown below: Figure 3 shown.
