Detailed Description
The following detailed description is made with reference to the accompanying drawings.
In the invention, the two-dimensional graph is not a symbolic two-dimensional model or two-dimensional identification in the prior art, but a two-dimensional graph capable of displaying the attribute of the controlled object.
The three-dimensional model in the invention is a three-dimensional graph capable of displaying the attribute of the controlled object, namely the fusion of the three-dimensional graph and the attribute.
The attributes of the controlled object in the present invention at least include the size, model, location, associated components, operating status, environment status, etc. of the controlled object. For example, a two-dimensional graph of the controlled object attribute is displayed, the size of the part size of the two-dimensional graph is in proportion to the real size of the controlled object, and the part connection position of the two-dimensional graph is consistent with the real situation. In particular, the three-dimensional component structure of the two-dimensional graph of the controlled object attribute completely coincides with the real component structure of the controlled object, and when a certain component of the controlled object moves or opens, the corresponding component of the three-dimensional graph is in a moving or opening state.
The picture frequency stream in the present invention means: a video stream of pictures can be formed. Video streaming refers to the transmission of video data, which can be handled as a steady and continuous stream over a network, for example.
In order to overcome the defects in the prior art, the invention provides a visual digital twin plant server embedded with a distributed control system, which can also be called a digital twin plant-based embedded distributed control system.
The visual digital twin factory server embedded in a distributed control system of the present invention, as shown in fig. 1, includes at least a two-dimensional module 1 and a three-dimensional module 2. And the two-dimensional module and the three-dimensional module are in communication connection in a priority or wireless mode. The two-dimensional module and the three-dimensional module can be one or more of an application-specific integrated chip, a server, a processor, a server group and a cloud server. The two-dimensional module 1 and the three-dimensional module 2 are both in communication connection with at least one operation terminal 5. The two-dimensional module 1 and the three-dimensional module 2 display a two-dimensional view and a three-dimensional view to be displayed through the operation terminal 5, and receive an operation instruction of an operator through the operation terminal 5.
The plant server is connected to the control device 4, and the control device transmits monitoring data and control state information of the controlled object to the plant server. Specifically, the two-dimensional module and the three-dimensional module simultaneously receive real-time data of the controlled object through the control device. The control device is used for controlling the equipment.
The operator terminal includes at least one operator station for displaying a two-dimensional view or a three-dimensional view of the two-dimensional module or the three-dimensional module and accepting input information of an operator so that the two-dimensional module and the three-dimensional module respond to the input information.
The two-dimensional module 1 is used to display a two-dimensional view of the controlled object in a two-dimensional manner, so that the operator can view and control the state of the controlled object in the two-dimensional view. Preferably, the two-dimensional module can display parameters and attribute data of all variables in the production process of the controlled object, can inform an operator of an unexpected situation in the production process in an acousto-optic alarm mode, can display a real-time or historical trend graph of process data in any combination or single-point mode, and can acquire a process safety interlock protection state and the like. Preferably, the data stored in the two-dimensional module is two-dimensional data. For example, the two-dimensional module defines the number, function, use, setting value, input/output data, alarm, and various related engineering design figures and data of the controlled object and each component of the controlled object. The two-dimensional module only stores the two-dimensional data has the advantages that the resources of other servers are not occupied, the workload of the three-dimensional module is favorably reduced, and the processing efficiency of the three-dimensional module is improved.
In response to an operation of the operator at the operation terminal 5, the two-dimensional module adjusts the display position in the two-dimensional view, thereby displaying the operating states of different controlled objects.
The three-dimensional module of the invention is used for displaying the controlled object in a three-dimensional mode and responding to the operation of an operator to display, control and view the current controlled object. Preferably, the controlled object in the three-dimensional view is displayed in a rendering manner, so that the operator can clearly view each part of the controlled object from various angles. Preferably, the designated controlled object in the three-dimensional view is displayed in a highlighted color to facilitate the operator to quickly find the designated controlled object. Preferably, the three-dimensional module receives the three-dimensional graphics from the graphics server 3 and renders the three-dimensional graphics, that is, the three-dimensional module of the present invention does not need to perform a light-weight process on the three-dimensional model, thereby reducing the processing amount for selecting and calling the three-dimensional graphics and reducing the workload of the three-dimensional module.
Preferably, the graphics server 3 is used to store static data, including both non-graphics type engineering data, such as data tables, specifications, etc., and graphics type engineering data. The graphic engineering data is, for example, a flow chart, a device manufacturing diagram, a floor plan, and the like. The image data in the present invention refers to data in a graphic manner, not data describing graphics. Preferably, the graphic server is further configured to fuse the attribute data of the controlled object with the graphic data to form a three-dimensional graphic of the controlled object. In the prior art, in the conventional three-dimensional graph, the three-dimensional graph of the controlled object is only a three-dimensional model which is arranged in a certain proportion with real equipment, the three-dimensional model only plays an exemplary role in a three-dimensional view, and the three-dimensional model cannot be changed in real time according to the attribute change of the controlled object. The invention fuses the graphic component of the controlled object with the real-time attribute data through the image server to form the three-dimensional graph of the controlled object in the real-time state, so that an operator can directly check the real-time state of the controlled object through the change of the three-dimensional graphic component in the three-dimensional view.
The three-dimensional module is used for acquiring the three-dimensional image, and the attribute data of the three-dimensional image are transmitted to the graphic server. Compared with a video device with angle limitation, the three-dimensional graph of the controlled object can be used for viewing and controlling the controlled object at any visual angle.
Preferably, the graphics server receives real-time data transmitted from the control device, and changes attribute data in the three-dimensional graphics in real time based on the real-time data.
The controlled object and each component thereof in the invention are coded according to a predefined uniform coding rule. And, the attributes of the controlled object are individually assigned in units of components.
This has the advantage that each component has a unique code. The same controlled object in the two-dimensional module and the three-dimensional module adopts the same code. The code of each component is a unique interface for uniquely calling various components. According to the two-dimensional module and the three-dimensional module, when various components of the controlled object are called, the attribute data can be called quickly and accurately according to the codes, errors are not prone to occurring, operations such as relation retrieval, analysis and screening are not needed to be carried out on the data, the calling speed of the attribute data of the controlled object is high, and the calling efficiency is high.
In the invention, the two-dimensional graphic component of the controlled object is mapped to the three-dimensional graphic component of the controlled object, so that an operator can position the two-dimensional graphic component in the three-dimensional view. Preferably, the operator can jump to the three-dimensional graphical component of the controlled object by clicking on the controlled object in the two-dimensional view. Alternatively, the operator can jump to the two-dimensional graphical component of the controlled object by clicking on the controlled object in the three-dimensional view. The operator can accurately and simultaneously position the controlled object in the two-dimensional view and the three-dimensional view through the mapping association setting, and jump between the two-dimensional graphic component and the three-dimensional graphic component based on the requirement, so that the operator can conveniently view and control the controlled object through the two-dimensional view and the three-dimensional view.
Preferably, in response to an operation instruction of the operator, the attributes of the controlled object can be displayed in parallel in two-dimensional and three-dimensional manners. After the attribute information of the controlled object is changed by the operating party, the attributes in the two-dimensional module and the three-dimensional module are synchronously changed in real time, so that the controlled object is displayed by the two-dimensional module and the three-dimensional module in a real-time display mode with consistent attributes all the time. Compared with the working mode of the two-dimensional module and the three-dimensional module in series in the prior art, the working mode of the two-dimensional module and the three-dimensional module in parallel does not occupy the bandwidth of a control network, has small workload, reduces the phenomenon of data delay display of the three-dimensional module and the two-dimensional module, and obviously improves the working efficiency of graphic display.
In the invention, the control device sends the attribute data of the controlled object to the two-dimensional module and the image server in real time, so that the attributes of the formed two-dimensional graph and the three-dimensional graph are real-time, and the real-time control of an operator on the controlled object is facilitated.
The server of the invention is embedded into a distributed control system, so as to form a distributed control system, namely a distributed control system, which can control a twin digital factory in real time. Fig. 2 shows a distributed control system of the present invention. As shown in fig. 2, the distributed control system of the present invention includes at least a production run management layer F1, a data service layer F2, a data application layer F3, an operation monitoring layer F4, and a control layer F5. The operation monitoring layer F4 and the control layer F5 are connected through a first gateway device. The data application layer F3 and the operation monitoring layer F4 are connected through a second gateway device. The data service layer F2 and the data application layer F3 are connected through a third gateway device. A first firewall device 61 is disposed between the first gateway device and the third gateway device. A second firewall device 62 is provided between the third gateway apparatus and the production operation management layer F1. A third firewall device 63 is disposed between the second gateway device and the third gateway device. The firewall is arranged, so that the key server can be prevented from being invaded from the outside, and the data security of the server is protected. Preferably, the twin digital factory server of the present invention is provided in the data application layer F3. The operation terminal 5 of the present invention is an operation monitoring layer F4, and includes at least a first operator station 51, a second operator station 52, and an engineer station 53. The number of operator stations and the number of engineer stations in the operation terminal are not limited to the number illustrated in fig. 2, and may be more. Preferably, the operation monitoring layer F4 further includes a database 44 for storing historical data of data collected by the control device. Preferably, the operation monitoring layer F4 further includes a time synchronizer 45.
Preferably, the control device 4 is in data connection with a plurality of controlled objects 50 through the unit module, so as to collect and transmit data of the controlled objects to the server.
Preferably, the data service layer F2 of the present invention at least includes a dispatcher 21, a production analysis client 22, a WEB server 23 and a protection server 24.
The scheduling station 21 is used for the operator to schedule the production of the controlled object and for inputting a scheduling operation instruction.
The production analysis client 22 is used for the operator to perform production analysis on the production process of the factory.
The WEB server 23 is for providing a WEB information browsing service.
The guard server 24 is used to listen for service requests submitted by other computers on the network and provide corresponding services.
The production operation management layer F1 includes at least a personnel location system 11, a database system 12, an advanced application terminal 13, and a WEB client 14.
The personnel positioning system 11 is used for acquiring personnel positioning information based on a positioning device carried or worn by a worker, and sending the personnel positioning information to the two-dimensional module, the graphic server and/or the three-dimensional module. The two-dimensional module fuses the personnel positioning information and the two-dimensional graph to form a real-time personnel drift position and a drift track at a real position.
And the graphics server fuses the personnel positions and the three-dimensional graphics to form the three-dimensional graphics with real-time personnel positioning based on the real-time personnel positioning information. The operator can view the attributes and real-time location information of the worker in real time through the three-dimensional view. The attributes of the staff members include at least name, image, job title, and the like.
Preferably, the person positioning device sends the real-time position data to the two-dimensional module, the graphic server and/or the three-dimensional module at preset time intervals.
Under the condition that the personnel positioning device is intelligent wearing equipment, the two-dimensional module responds to real-time position information of the intelligent wearing equipment and displays a two-dimensional view of a controlled object within a specified range of a real-time position on a display screen of the intelligent wearing equipment. For example, when the staff member arrives at the a area, a request to view a two-dimensional view within 5m of the vicinity is issued by the smart wearable device. The two-dimensional module responds to the request of the intelligent wearable device and displays a real-time two-dimensional view of the controlled object within 5m of the real-time position of the worker on the specified display screen. Preferably, the wearable device comprises one or more of intelligent glasses, augmented reality equipment, an intelligent bracelet and an intelligent chest card.
Under the condition that the personnel positioning device is the intelligent wearable equipment, the three-dimensional module responds to real-time position information of the intelligent wearable equipment and displays a three-dimensional view of the controlled object within a specified range of the real-time position on a display screen of the intelligent wearable equipment. For example, when the staff arrives at the a area, a request is issued to view a three-dimensional view within 5m of the vicinity through the smart wearable device. The three-dimensional module responds to the request of the intelligent wearable device and displays a real-time three-dimensional view of the controlled object within the range of 5m of the real-time position of the worker on the designated display screen. The method is beneficial for workers to check the production condition and the safety condition of the nearby controlled object in real time in the physical factory and control the controlled object.
The two-dimensional module or the three-dimensional module responds to a viewing request of the intelligent wearable device for a specified controlled object, and displays a real-time two-dimensional view or a real-time three-dimensional view of the controlled object on a specified display screen. Through the cooperation use of intelligent wearing equipment, the staff just can look over the two-dimensional view or the three-dimensional view that have attribute information of controlled object near controlled object to master controlled object's true attribute condition, be convenient for the staff patrol controlled object's production condition.
Wherein, in response to the coded information of the controlled object input by the wearable device, the visual digital twin factory server feeds back a two-dimensional graph of the controlled object and/or a three-dimensional graph associated with the controlled object to the wearable device.
In response to the wearable device clicking on the two-dimensional graph of the controlled object, the visual digital twin factory server feeds back the real-time three-dimensional graph of the controlled object to the wearable device. The staff can carry out similar operation like the operator station on wearable equipment's display screen promptly, looks over the real-time condition of controlled object at any time.
In the prior art, the number of controlled objects of a factory is huge, and because reference of a two-dimensional view is not provided, an operator searches and views the controlled objects according to a connection relation, so that the main viewed objects are easily blurred in impression, and the viewing efficiency is reduced due to more and more controlled objects.
Preferably, the three-dimensional view of the present invention provides a three-dimensional view containing the controlled object and the device associated with the controlled object within the depth range according to the depth range request data specified in the two-dimensional scene.
The depth of field range of the present invention refers to a display range in which a clear image can be formed on a display when a view of a limited distance is acquired. The depth field region is a distance range in which a three-dimensional graphic component of a controlled object can be clearly displayed.
The area delineated on the two-dimensional view may be a specified depth of field range. The depth of field range contains a plurality of controlled objects. When the operator defines the depth of field area, the three-dimensional view displays the three-dimensional graphic component of the controlled object according to the depth of field range which can be specified.
For example, the operator defines a depth area of the three-dimensional view in an undefined geometric shape on the displayed two-dimensional view, and the two-dimensional module transmits the depth information to the three-dimensional module. The three-dimensional module responds to the depth of field information and displays the depth of field area in a three-dimensional graph.
When the operator views the three-dimensional figure and its attributes in the designated depth of field area, the picture is clear. When an operator checks the edge of the scene depth area, the three-dimensional graph in the edge is high in definition, and the definition of the three-dimensional graph outside the edge is reduced, so that the operator is prompted to check the content exceeding the scene depth area, the operator can plan the checked scene depth area again, and the situation that no clear target exists in checking is avoided.
Preferably, for a device with abnormal attributes, the two-dimensional graph displays the two-dimensional graph of the device sending alarm information in a highlighted color and/or identification, and at least one other device associated with the abnormal problem of the device. I.e. the operator is able to see clearly the device issuing the alarm and the associated device associated with the alarm in a two-dimensional view. The operator can define the depth of field area containing the alarm device and the associated device on the two-dimensional view, and can check the three-dimensional graph and the attribute information of the alarm device and the associated device on the three-dimensional view in a high-definition mode. By highlighting the alarm device and the related devices thereof, an operator can quickly determine the devices needing to be checked in a key mode, and the defect that the devices are not checked in a targeted mode to find out the reason of the alarm is overcome.
If the defining mode of the depth-of-field area is not set, when an operator views the device of the three-dimensional view on the display device, the three-dimensional server cannot determine the device to be viewed by the operator next step, and only can display all the devices in the current three-dimensional view in a high-definition mode. In practice, however, there are many three-dimensional graphics of the device and its attributes that the operator will not view in detail. This results in the three-dimensional server sending an excessive amount of unnecessary data to the display device, resulting in data delay at the display device side and slow update of the three-dimensional graphics, affecting the screen update speed of the display device. Preferably, the display device includes a two-dimensional display, a three-dimensional display, and a display device of a wearable device.
According to the invention, through the designation of the depth of field area, the three-dimensional server can reduce the data volume of the data transmitted to the viewed display equipment. And the three-dimensional server screens the high-definition data of the three-dimensional graph and the attribute data thereof based on the depth-of-field area sent by the two-dimensional server and the equipment list in the depth-of-field area, and sends the high-definition data to the display equipment. That is, the three-dimensional server can filter and deliver data targeted based on the depth of field area, thereby reducing the sending of a large amount of unnecessary data.
Preferably, the depth of field region can be arranged not only in a two-dimensional view but also in a three-dimensional view. When the operator defines a depth of field area in the three-dimensional view, the three-dimensional server can search data according to the depth of field area and give a list of devices in the depth of field area. And the operator checks the required information according to the form.
Preferably, the invention preliminarily displays the three-dimensional graph of the controlled object at a preset angle. And the three-dimensional module adjusts the display angle of the controlled object to a specified angle in response to the click information or the display angle request of the operator. Therefore, the display is beneficial to the operation condition of each angle of the controlled object to be checked by the operation party, and the limitation of checking the angle is avoided.
It should be noted that the above-mentioned embodiments are exemplary, and that those skilled in the art, having benefit of the present disclosure, may devise various arrangements that are within the scope of the present disclosure and that fall within the scope of the invention. It should be understood by those skilled in the art that the present specification and figures are illustrative only and are not limiting upon the claims. The scope of the invention is defined by the claims and their equivalents.
