Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the embodiments of the present application will be described in detail hereinafter with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be arbitrarily combined with each other.
The conventional monitoring operation system has the following main problems:
in terms of data sharing, in a traditional monitoring operation and maintenance system, data with different professions and different sources are often heterogeneous, such as an AFC device running state, video monitoring data, sensor data and the like, are usually stored and displayed respectively, and lack of close connection with an actual model, so that the information management mode can cause a plurality of inconveniences to maintenance work.
In terms of data analysis, monitoring the accumulation of operational data is of great value for most building facilities and equipment. In the conventional monitoring operation and maintenance system, the integration degree of the data is insufficient, and the inherent connection between the data is difficult to deeply mine, so that the operation and maintenance efficiency is reduced.
In the aspect of data visualization, in a traditional monitoring operation and maintenance system, information and states of equipment and facilities are usually displayed by using two-dimensional drawings, and are difficult to correspond to an actual physical model. Therefore, in the display mode, data presentation and fault feedback are not visual enough, and the actual running state of equipment and facilities is difficult to reflect, so that the overall operation and maintenance management efficiency is influenced.
Aiming at the technical problems, the scheme provided by the embodiment of the application introduces digital twinning and light BIM model technology, the digital twinning technology synchronizes physical assets and digital assets, all data elements in the digital twinning assets are linked to each stage and each flow by utilizing digital means, and are innovated and applied in a different output mode, and are combined with the light BIM model technology to perform visual display, so that the data presentation is more real and visual, the intelligent level and efficiency of the equipment operation and maintenance are conveniently improved, and the intelligent operation and maintenance processing device and the display method of the equipment based on the digital twinning and light BIM model technology are accordingly developed.
The method and the system adopt a digital model for establishing the combination of the BIM information model and the equipment information, simultaneously contain the equipment information in the BIM information model, digitally convert the resources required in the subway management process by means of wireless sensing, communication technology and the like, form an interactive human-computer interface, and comprehensively and actively reflect the service running condition. And the new generation technologies such as machine learning and the like are combined for analysis and modeling, the operation data are analyzed in real time, and the service condition is analyzed and diagnosed.
The urban rail transit system provided by the embodiment of the application comprises a plurality of mutually independent sub-models, wherein each sub-model is obtained by dividing a building information model BIM of the urban rail transit system according to a physical area.
Specifically, BIM data corresponding to areas with adjacent physical positions or areas on the same floor are used as data of the same submodel according to the positions of the areas in the BIM; or,
and according to the functions corresponding to the areas in the BIM model, taking BIM data corresponding to the areas serving as the same functional area as data of the same sub-model.
For example, sub-models in several ifc formats are exported by location or function through BIM modeling software (e.g., revit). For example, the subway station model can be divided into a station hall layer and a station platform layer according to physical positions, and can be divided into a plurality of sub-models such as a public area, a plurality of equipment rooms and the like according to functions.
Further, the sub-model is a sub-model after light weight treatment;
the lightweight sub-model is obtained by the following method, comprising:
converting the original submodel in rvt format into the submodel in ifc format;
and setting data filtering conditions in a pre-installed high topo BIM conversion platform, and converting the sub-model in the ifc format to obtain a light sub-model.
Aiming at the problem that the traditional BIM model generally depends on professional software and files, the 3D visualization software Hightopo (hereinafter referred to as ht) is adopted to lighten and analyze the BIM equipment model into a format recognizable by a browser based on the Hightopo plug-in using a WEB terminal. The specific operation is as follows:
1) Exporting a BIM model in rvt format to ifc format using revt (BIM editing software)
2) Uploading the model in the ifc format to a BIM conversion platform developed by hightopo, and setting the operations of coding the model, filtering the model and the like on the platform.
3) Downloading the converted model on the platform, wherein the volume of the converted model is about 5% of that of the model before conversion, and then utilizing hightopo
4) And importing the converted submodel into a webpage through js codes by using a preset webpage API interface web-API.
The light weight processing can solve the problem that the traditional BIM model generally depends on professional software management and has larger files.
Fig. 1 is a flowchart of an operation and maintenance management method of an urban rail transit system according to an embodiment of the present application. As shown in fig. 1, the method includes:
102, determining a target sub-model corresponding to the operation and maintenance management request from the plurality of sub-models;
104, receiving an operation and maintenance management request set in the target submodel;
and step 105, triggering an execution flow of the operation and maintenance management request.
According to the method provided by the embodiment of the application, the BIM model is split into the plurality of sub-models, the information recorded in the sub-models is utilized to respond to the operation and maintenance management request, the data loading amount is reduced, and the data loading speed is improved.
Preferentially, before determining a target sub-model, determining a target service scene corresponding to the operation and maintenance management request, wherein each service scene corresponds to one or more sub-models;
reading data of a sub-model corresponding to the target service scene;
and when the target submodel is output, only the data of the target submodel is loaded from the read data to perform output operation.
Specifically, one model is selected from the light sub-models to be used as an inlet model, and the selection of the inlet model is determined according to functional requirements. For example: the hall layer is the key point of the patrol work, and then the hall layer model is used as an entrance model, and only the entrance model is loaded when the BIM scene is loaded.
When the user browses the current sub-model and wants to view the models of other areas, the corresponding sub-model can be loaded through the program. For example, the detached subway station has two parts, namely a station hall layer and a platform layer, and when the subway station is initialized, a user only needs to load the station hall layer, and can freely operate without waiting for loading of all models, and when the user clicks the 'check platform layer', the program loads the platform layer model by monitoring a clicking event. Therefore, the volume of the first loading model is reduced in a step loading mode, the time consumed for opening the scene can be greatly reduced, and the smaller the model volume of the first loading is, the more obvious the loading speed is increased compared with the mode of loading all models at one time.
Considering that BIM modeling is very focused on detail processing, some details (such as text models, building lines and the like) consume more CPU and GPU performances, and meanwhile, the business functions are not necessarily helped more, and for the details, a more performance-saving map can be adopted to replace an original model, so that BIM is subjected to light-weight processing in detail.
The method establishes a basic database of the equipment and associates the position information of the equipment; the equipment record database is established, the equipment basic database and the equipment record database can be updated when equipment or parts are replaced, overhaul record data are associated with equipment records, and full life cycle tracking and management of the equipment are realized; and (3) establishing a list chart and a historic chart of the equipment, carrying out data and graphic display on the equipment historic chart of the existing scattered paper version, and displaying information such as equipment, maintenance records, faults and the like on the list chart and the historic chart according to the equipment chart commonly used by each professional, so that the system operation is more humanized and more convenient.
An equipment overhaul database is established, an overhaul record form is solidified into the system, overhaul operation flow and standardized management are realized, real-time management of overhaul progress is realized, and real-time management of the working condition of an overhaul worker is realized; the paperless maintenance record is realized, and automatic analysis and treatment of maintenance abnormal data are supported. For equipment state monitoring, the system can acquire real-time equipment data, conduct online equipment fault prediction by using a fault model, and prompt the predicted equipment fault in a human-computer interface.
In order to combine the digital twin technology with actual business more tightly, the method is mainly used for realizing functions such as equipment fault prediction, the real-time predicted value calculated and generated by a dynamic equipment model is compared with the real-time value of an equipment measuring point through a big data analysis platform and a fault prediction analysis system, equipment fault state early warning is issued according to a comparison result, a feedback result is displayed on the digital twin model in a visual way, and other functions of the model and a software platform assist operation and maintenance personnel to finish inspection and maintenance tasks.
The method not only completes the generation of the digital model, but also combines the digital model with the operation and maintenance stage business process, and designs a business process management system by means of the digital model, including but not limited to the functions of intelligent video inspection, intelligent alarm, business scene customization and the like.
1) Intelligent video inspection
In an exemplary embodiment, the triggering the execution flow of the operation and maintenance management request includes:
when the operation and maintenance management request is a patrol request, scaling the plane area corresponding to the sub-model to obtain a scaled plane area;
0 and 1 are used for representing barriers and paths, and the numerical value of each coordinate point in the scaled plane area is determined to obtain a two-dimensional array;
obtaining a routing inspection path of the scaled plane area based on the two-dimensional array, wherein the routing inspection path comprises routing inspection coordinate points recorded in sequence;
converting each inspection coordinate point sequentially recorded in the scaled plane area into a target coordinate point sequentially recorded in the plane area corresponding to the sub-model;
and generating a target inspection path by using the sequentially recorded target coordinate points.
The converting each inspection coordinate point sequentially recorded in the scaled plane area into a target coordinate point sequentially recorded in the plane area corresponding to the sub-model includes:
obtaining a scaling ratio N corresponding to the scaled plane area, wherein the value of N is greater than 1;
and expanding the numerical value of each inspection coordinate point by N times to obtain the numerical value of the target coordinate point.
After the target inspection path is generated by using the sequentially recorded target coordinate points, the method further comprises the following steps:
acquiring a coordinate point of equipment with the equipment type of a camera in a target inspection path from the equipment types recorded in the sub-model;
and reading the inspection data from the target equipment corresponding to the coordinate point of the equipment.
The inspection work is a task that each equipment maintainer is subjected to. In conventional inspection work, a worker physically checks the operation condition of the equipment and the surrounding environment on site, and manually records an inspection report. This process is not only labor and force intensive, but is also very unfriendly to new on-duty workers, for example, unfamiliar with the location of the equipment or unfamiliar with the field environment, greatly extending the task completion time. Therefore, the simulation characteristics of BIM and the like are utilized, and a route calculation algorithm is combined to replace on-site inspection of staff, so that the working efficiency is improved.
And (3) light weight treatment of a BIM model: and the high topo plug-in of the WEB terminal is utilized to lighten and analyze the BIM equipment model into a format recognizable by a browser. For the inspection function, the processed file needs to at least retain the tag attribute and the equipment number of the equipment model besides retaining the three-dimensional information of the processed file. Since in the industrial internet, the device number can be associated with the asset management system and the integrated monitoring system, other information of the device can be obtained from the system for device number management without being stored in the BIM model.
the tag attribute is used for acquiring a model object in a program and is set when the model is split. The lightweight model also needs a developer to split the part to be controlled in the model, otherwise, the model is obtained as a whole, and the equipment or the building structure in the model cannot be controlled independently. The specific splitting process is as follows: the developer sets tag attributes (used as unique identifiers of split models) for sub-models which want to be controlled independently in the models on a BIM platform of Hightopo, and each model with the tag attributes can be controlled independently in a program (corresponding model objects are acquired through tag identifiers in the program, and a model method is called according to an api document so as to complete control operation).
The device number is used to interface with systems such as device asset management (these systems typically use the device number as a unique identifier) and is typically set at the time of BIM modeling, and if the device number in the model is missing, then the device number of the model needs to be manually set to tag attribute in the BIM platform to ensure that the model can be identified while also associating the asset system.
Developing a patrol algorithm map according to the light BIM model: the map consists of a two-dimensional array, 0 representing the path and 1 representing the obstacle.
Take a two-dimensional array of 5*6 as an example for illustration:
[1,1,1,1,1,1,]
[1,0,0,1,0,1,]
[1,0,0,1,0,1,]
[1,0,0,0,0,1,]
[1,1,1,1,1,1,]
if one wants to reach [1,4] from the array coordinates [1,1], one needs to bypass the points with values of [1,3] and [2,3] as 1, and accordingly one array path can be obtained: [1,1],[2,1],[3,1],[3,2],[3,3],[3,4],[2,4],[1,4].
And marking corresponding points of the obstacle and the passage in the array according to the coordinates of the BIM model, and calculating a route for use by using a route algorithm. According to different required fineness, the algorithm map can be scaled according to the requirement, and the occupied volume of the map can be reduced. For example: the coordinate range of the BIM model is 100×100, and the algorithm map is scalable to a two-dimensional array of 50×50.
Making a patrol task:
fig. 2 is a flowchart of a method for managing an inspection task in an urban rail transit system according to an embodiment of the present application. As shown in fig. 2, cameras associated with the inspection route (the relevant camera information is acquired from the background while the cameras are selected) are sequentially selected and sent to the background program, and the background program stores the equipment codes of the cameras and the coordinates thereof in the inspection map into the inspection task recording table of the database. The basic information of the camera is stored in a camera data table of the database. The selection sequence of the cameras is the sequence of the tour in the task, and the coordinate positions of the cameras can be marked in the tour path, for example, coordinates (2, 2) and (2, 5) in the 5*6 array are the coordinate positions of the cameras.
Calculating a patrol path by using an astar algorithm:
and sequentially selecting the coordinate information of two adjacent cameras from the established algorithm map as input to obtain a group of routing inspection shortest route formed by the array, wherein the path between the adjacent cameras can be formed by one or more sections of sub-paths, and each section of sub-path is a straight line. When the route is a straight line, only two end points of the straight line are reserved, and the array between the end points is omitted, so that the space occupied by the route array can be greatly reduced.
Coordinate conversion from the inspection path to the 3D path:
since the algorithm path is calculated based on the scaled version map and has a difference from the real coordinates in the 3D scene, the algorithm path cannot be directly used for the tour function. We therefore need to formulate a scaling formula from the algorithmic path to the 3D path based on the scale of the algorithmic map scaling. For example, we get an algorithm path based on the map of 5*6 in step two: [1,1], [2,1], [3,2], [3,3], [3,4], [2,4], and [1,4], the conversion formula of the path is [ X (3D), Y (3D) ]= [ 10X (algorithm), 10X Y (algorithm) ], assuming that the scaling ratio at this time is 10. The 3D tour path is shown as [10,10], [20,10], [30,20], [30,30], [30,40], [20,40], [10,40]
Considering that the patrol is performed on the ground (a plane), the coordinates on the vertical axis do not change during the patrol, the ordinate can be set to be a constant, the specific value can be adjusted according to the visual effect in the actual patrol, and here, assuming that the ordinate value is 15, the 3D path obtained finally is:
[10,10,15],[20,10,15],[30,10,15],[30,20,15],[30,30,15],[30,40,15],[20,40,15],[10,40,15]
restoring the inspection work in the BIM scene:
fig. 3 is a flowchart of a method for restoring an inspection task in an urban rail transit system according to an embodiment of the present application. As shown in fig. 3, the first camera to be inspected is positioned according to the coding information of the first camera in the inspection task, and a monitoring picture and a remark column of the camera are popped up to record the inspection work conveniently; after the recorded content is filled, the visual angle attribute in the BIM scene is moved to the next device along the calculated inspection path to repeat the work until the last device is inspected to complete the inspection task.
2) Intelligent alarm
In one exemplary embodiment, each sub-model records a device identification of the device;
the triggering the execution flow of the operation and maintenance management request comprises the following steps:
when the operation and maintenance management request is a device alarm request, determining a position corresponding to a device identifier in the target sub-model;
and outputting an alarm prompt at a position corresponding to the equipment identifier.
In the related art, the alarm can only be informed to a worker to check the alarm in a text information and bell sound mode, and the mode is difficult to intuitively reflect the alarm information to maintenance personnel, such as whether the alarm content is true, whether the equipment has false alarm, where the specific position of the alarm equipment is, and the like, so that people need to understand and think the alarm content to obtain accurate judgment. And the characteristics of BIM model parameterization and information completeness are combined to perfect the flow of alarm processing, so that the efficiency of alarm processing is improved.
Fig. 4 is a flowchart of a method for restoring an inspection task in an urban rail transit system according to an embodiment of the present application. As shown in fig. 4, the implementation flow of the intelligent alarm is as follows:
(1) Opening up a data interface: the component information and the coordinate information of the equipment are associated with the equipment management system, so that the positioning processing during alarming is convenient. The specific association process is as follows: storing the binding relation between the device codes, the component codes and the measuring points in a database. Binding the equipment codes and the component codes to the equipment model and the component respectively. During display, relevant information of equipment, such as equipment measuring points, measuring point real-time values and the like, needs to be requested to the back-end service according to equipment codes. And rendering the data to a front-end display interface after the data are acquired.
(2) And (5) processing alarm information: after receiving the alarm information, acquiring equipment coordinates according to the equipment information in the alarm, moving the visual angle of the BIM scene to the front of the BIM equipment for the alarm according to the coordinates, popping up specific alarm information at the equipment accessory, and adding red flashing characteristic to the alarm equipment for reminding workers. When all alarms of the device binding are released, the BIM device stops flashing back to the normal color.
3) Business scenario customization
In an exemplary embodiment, before determining the target sub-model, determining a target service scenario corresponding to the operation and maintenance management request, wherein each service scenario corresponds to one or more sub-models;
