In addition, among the prior art, when carrying out the VR show to the BIM model, one mode relies on the BIM platform to demonstrate from taking the VR module, and the VR image of this kind of show mode show can not update according to the real-time running information of object equally. And in another VR display mode of BIM data, the BIM model is often required to be converted and extracted in a basic format, and then geometric form lightweight and effect processing are performed to a certain extent, so that the model is used as a model for VR experience subsequent development, appearance effect optimization is performed, and specific animation interaction is performed, so that the processed data only has appearance and shape, and the BIM data cannot be read in real time.

The processor 130 is used for executing executable modules stored in the memory 120, such as software functional modules and computer programs included in the BIM model dynamic display device 110.
In order to solve the above problems, the present embodiment of the application provides a BIM model dynamic display method applied to the electronic device 100, which is described in detail below with reference to fig. 2, and the method includes steps S010 to S060.
And S010, acquiring BIM data of any monitored object in the target scene.
Specifically, building information model BIM data of any monitored object in the target scene is acquired, where the BIM data of any monitored object includes a first position parameter of the any monitored object in the target scene and information of an appearance form of the any monitored object.
And step S020, acquiring any one of the monitored objects by using the BIM data of the monitored object to acquire the running animation of the monitored object.
Specifically, according to the BIM data of the any monitored object, a running animation for simulating the running of the any monitored object in the target scene is obtained, where the running animation includes sub-running animations respectively corresponding to each running stage in the running process of the any monitored object.
And S030, detecting whether the real-time running information of any monitored object in the database changes.
And step S040, if the real-time running information of any monitored object changes, acquiring a first spatial geographical position parameter of the any monitored object in the GIS platform.
Specifically, a first spatial geographic position parameter of the any monitored object in the GIS platform is obtained according to the first position parameter of the any monitored object.
And step S050, acquiring the sub-operation animation corresponding to any monitored object.
Specifically, a sub-running animation corresponding to the running stage parameter in the real-time running information after the change of the any monitored object is obtained from the running animation corresponding to the any monitored object.
Step S060, displaying the sub-operation animation on the GIS platform at a position corresponding to the first spatial geographic location parameter, so as to realize dynamic display of the any monitored object on the GIS platform.
The embodiment is used for acquiring the running animation corresponding to each monitored object, and establishing the corresponding relation between each sub-running animation in the running animation and each running stage in the running process of the monitored object, which is equivalent to the corresponding relation between each sub-running animation and the running stage parameter of each running stage in the running process of the monitored object. And determining the sub-operation animation to be displayed according to the real-time operation information stored in the database and displaying the sub-operation animation. Therefore, the purpose of dynamically displaying the monitored object on the GIS platform can be realized according to the BIM data of the monitored object.
Optionally, in this embodiment, the specific steps of step S020 are: first, the BIM data of any monitored object is converted into first model data supported by 3DS Max software. And then inputting the first model data into 3DS Max software for animation recording to obtain the running animation.
The embodiment is used for independently exporting each monitored object into a format supported by 3DS Max software, such as a.
When animation is specifically produced, animation recording can be performed according to animation types corresponding to different operation stages of the monitored object, for example, rigid body animation and skeleton animation can be produced, model texture replacement can also be performed, and the like.
And after the running animation is produced, detecting whether the real-time running information of any monitored object in the database changes, if so, searching the sub-running animation corresponding to the changed real-time running information from the running animation, and displaying the sub-running animation at a corresponding position in the GIS platform. And loading the corresponding data in the SGM format to the GIS platform for display.
In this embodiment, when detecting whether the real-time operation information of any monitored object in the database changes, the database may be monitored through a function, and then when the function monitors that the real-time operation information changes exist in the database, step S050 is executed according to the changed real-time operation information.
For example, the connection of the SuperMap platform to the database may be established in the following manner. In the SqlSever database, real-time running information in the database can be monitored through a SqlDedependency function, and when the SqlDedependency function monitors that the real-time running information in the database changes, an OnChange event is automatically triggered, so that the purpose of automatically updating the displayed sub-running animation by the system is achieved. Specifically, a SqlDedependency connection can be initialized, then the connection between the database and the SuperMap platform is established through the SqlConnection object and the SqlCommand object, and a Transact-SQL statement is defined. Then, a new SqlDedependency object is created or a defined SqlDedependency object is used, namely, a SqlNotification request object is created and is bound with the SqlCommand object, wherein the SqlNotification request object comprises an identifier for uniquely identifying the SqlDedependency object. The sqlnnotificationrequest object also starts a client listener. An event handle is then subscribed to the OnChange event of SqlDependency. Then any Execute method of the SqlCommand object is used to Execute the SqlCommand, because the SqlCommand and is bound with the SqlNotification request object, the database server considers that it must generate a SqlNotification request and the queue message points to the dependences queue. And finally, closing the connection of the SqlDedependency to the server for storing the running information.
After the above connection operation, if any user modifies the data we monitor, Microsoft SQLServer will monitor this modification, throw a notification and give it to the client created by sqldependency. After receiving the notification, the client listener locates the associated SqlDependency object and triggers an OnChange event. And making corresponding sub-running animation display when the data is changed.
The real-time operation information is stored in a data table, and the data table for storing the real-time operation information can comprise fields (column names), data types and 'allowed Null values' for representing whether a certain field is empty or not. The fields comprise model identification information ID, database server identification information SysType, Operation information Operation, equipment identification information Name, Time information Time and detail information Details, and the ID fields are used for identifying the model of the equipment to be monitored in the GIS platform. The operation type is a field record operation type and can be used for showing what type of animation is shown on the GIS platform, and the field record operation type has three states of 0, 1 and 2, wherein 0 is a rigid body animation type, 1 is a skeleton animation type, and 2 is a model texture replacement type. The Name field is used for recording the Name of an object to be monitored in practice. The Time field records the Time at which the operation occurred and also represents the Time at which the animation occurred.
For example, the animation types supported by the SuperMap include: rigid animation, skeletal animation, model texture replacement, and the like. The rigid Animation is an Animation class in the SuperMap, the attributes of the class are StartTime (used for obtaining or setting the starting Time position of the Animation), EndTime (obtaining or setting the ending Time position of the Animation), IsEnabled (obtaining or setting whether the current Animation is available), the attributes are used for setting the starting Time and the ending Time of Animation playing, the Animation action of a certain Time period of a model can be played, and further the control on the rigid Animation is finished, for example, the Time in a Time field is used as the starting Time and the ending Time, and the Animation corresponding to the Time is played; that is, Time may be used as a run phase parameter. Skeleton animation is a Nodeanimation class in the SuperMap, and the class has a method SetTrack (setting a motion track for the skeleton animation), and can complete the effect of the motion of a model along a specified route by binding a path to the model; the texture replacement animation can use Mesh class in the SuperMap, a grid surface set of the three-dimensional model geometric object is obtained through the class, and the control of the texture replacement of the model can be completed by setting the Material of the grid surface, namely the Material attribute.
How to perform the dynamic display of the monitored object is further described below with reference to detailed examples.
For example, a record ID is newly added to a data table storing real-time operation information: 0001, SysType: 0, Name: signal lights, Details: and the red light, namely 2019/8/18/09:45:30, represents that the signal light animation model with the ID of 0001 in the scene is changed from the green light to the red light at 2019/8/18/09:45:30, the client side acquires the signal light model with the ID of 0001 in the three-dimensional scene after monitoring the record, replaces the green texture with the red texture in a texture replacement mode, and then displays the sub-operation image in the texture replacement process on the GIS platform.
For another example, a new record ID is added to the data table storing the real-time operation information: 0002, SysType: 1, Name: disconnecting switch, Details: and switching off, namely that the Time is 2019/8/18/09:50:00, the isolating switch animation model with the ID of 0002 in the scene is changed from a switching-on state to a switching-off state at 2019/8/18/09:50:00, after monitoring the record, a client program acquires the isolating switch model with the ID of 0002 in the three-dimensional scene, and the running animation in the switching-off stage is played in a mode of playing the animation in a certain Time period through the animation control related technology introduced above, so that the real-Time driving of the rigid animation can be completed.
For another example, the data table storing the real-time operation information has a new record ID: 0003, SysType: 2, Name: bullet train CRH380B, Details: entering a garage, wherein the Time is 2019/8/18/09:55:00, the garage represents that the motor car animation model with the ID of 0003 in the scene enters the garage at the Time of 2019/8/18/09:55:00, after the client program monitors the record, the motor car model with the ID of 0003 in the three-dimensional scene is obtained, and the motor car garage entering animation is completed through the animation control related technology introduced in the embodiment and the skeleton animation binding motion path mode, so that the real-Time driving of the skeleton animation can be completed.
Optionally, in this embodiment, before the step S030, GIS data may be obtained, where the GIS data includes target scene three-dimensional model data forming a target scene where each monitored object is located and second spatial geographic position parameters of each background object in the target scene in the GIS platform. And then displaying the background objects on the GIS platform according to the second spatial geographic position parameters of the background objects in the GIS platform to obtain a three-dimensional model of the target scene. At this time, step S060 specifically is to display the sub-operation animation in the three-dimensional model of the target scene at a position corresponding to the first spatial geographic position parameter.
The embodiment is used for constructing the three-dimensional model of the background object in the environment (target scene) where the monitored object is located, and displaying the monitored object based on the display result of the three-dimensional model of the target scene, so that the monitored object and the background object in the environment where the monitored object is located can be combined to be displayed, that is, the monitored object is displayed in the three-dimensional model of the target scene.

And importing the second model data into the GIS platform, displaying the building in a target scene three-dimensional model of the GIS platform according to the third spatial geographic position parameter, and obtaining a new target scene three-dimensional model.
The method and the device are used for adding the building in the environment where the monitored object is located in the target scene three-dimensional model, so that the monitored object is combined with the environment more closely and is closer to the actual situation.
Referring to fig. 4, optionally, in this embodiment, after the step S010, the method further includes the step S210 to the step S260.

And step S250, acquiring the target sub-running animation corresponding to the animation identification.
Step S260, acquiring target information conforming to the type of the target information from third model data corresponding to the target sub-operation animation.
Specifically, according to the corresponding relation, target information conforming to the target information type is obtained from third model data corresponding to the target sub-operation animation.
The embodiment is used for establishing the relationship between the running animation of the monitored object and the BIM data of the monitored object, and then when the related information of the monitored object needs to be inquired, the corresponding data is inquired from the data table according to the established relationship between the running animation of the monitored object and the BIM data of the monitored object. By converting the data and storing the third model data in the data table, the problem that the attribute information of the BIM data is lost after the BIM data is subjected to intermediate format conversion can be solved.
For example, when a user clicks a monitored object whose related information needs to be queried in an interface showing an animation with a mouse, the electronic device 100 queries the related information of the monitored object from the data table by obtaining an animation identifier of a sub-run animation of the monitored object, and displays the information on the interface.

When the GIS platform is a SuperMap platform, a user can browse any position in a three-dimensional scene in a mode of dragging a mouse in the displayed sub-operation animation when monitoring the monitored equipment. The user may also query the three-dimensional coordinates of any one device. The embodiment can also perform accurate measurement calculation of length, area, height and the like in the three-dimensional scene.
