Description

Technical Field

[0001] The present invention relates to a device for visualizing rolling process information of a rolling line of an iron and steel complete set of equipment. Background Art

[0002] In the rolling line of a steel plant, it is important to accurately grasp the rolling process information including the rolling equipment and the rolled material. Therefore, in the past, the following method was used: using an image device called ITV (Industrial Television) or an animation display on the screen of HMI (Human Machine Interface) to provide various rolling process information in a visually easy-to-understand manner. For example, Patent Document 1 proposes a manufacturing performance image display system that stores a dynamic image obtained by shooting a product being manufactured by a camera and an image based on manufacturing-related data as an animation file, thereby quickly providing an image representing the manufacturing performance of the product.

[0003] On the other hand, there may be places where no camera is installed on the rolling line. In addition, the dynamic image shooting range of the camera is limited, so there may be places that become blind spots of the camera. In these places, it is difficult to visually grasp the rolling process information accurately, and the grasp of the state of the rolling process is restricted. Therefore, when improving equipment maintenance and improving product quality to improve the yield rate, it will hinder the correct situation judgment and become a factor that induces wrong countermeasures.

[0035] 1. First Implementation

[0036] 1-1. Configuration of Visualization System of First Embodiment

[0037] The system of the first embodiment of the present invention is described using the accompanying drawings. The system of the present embodiment is a system that visualizes and displays the rolling process information of the rolling line of the iron and steel plant through three-dimensional expression. Hereinafter, the system of the present embodiment is referred to as a visualization system. In addition, the systems of the second to fourth embodiments described later are also systems that visualize the rolling process information of the rolling line of the iron and steel plant, similar to the system of the present embodiment. These systems are also referred to as visualization systems.

[0038] use Figure 1The configuration of the visualization system of the present embodiment is described. The visualization system 1 of the present embodiment visualizes and displays the rolling process information provided by the control system 20 through three-dimensional expression. The control system 20 includes a process computer 21 that performs process calculations for controlling the rolling process, a controller 22 that controls the actuators of the rolling line according to the calculation results of the process computer 21, and a data collection system 23 that collects the rolling process information. The rolling process information is information indicating the current state of the rolling process, and is collected from the process computer 21, the controller 22, and a plurality of process sensors (not shown) arranged in the rolling line. The process computer 21, the controller 22, the data collection system 23, and the process sensors are connected via a control network 24.

[0039] The visualization system 1 includes a visualization device 11 for visualizing rolling process information, a three-dimensional animation display device 30 as a three-dimensional display device, and an XR (cross reality) display device 40. The visualization device 11 is connected to the control network 24. The rolling process information collected by the data collection system 23 is sent from the data collection system 23 to the visualization device 11 via the control network 24 in real time.

[0040] The visualization device 11 includes a processor 101, a program memory 102, a specification information memory 103, a communication module 104, and a user interface 105. The processor 101 may be a CPU, a GPU, a RISC, a DSP, an FPGA, an ASIC, a PLD, or other processing units, or a combination of two or more of these, or a dedicated processor for the visualization device 11. In the present embodiment, the number of processors 101 is one, but the visualization device 11 may also include a plurality of processors 101.

[0041] The program memory 102 is communicatively coupled to the processor 101. The program memory 102 stores a program consisting of a plurality of instructions INST executable by the processor 101. The program consisting of the instructions INST can be obtained using a non-temporary storage medium readable by a computer, or can be obtained via a network. In addition, the program memory 102 can also be built into the processor 101.

[0042] The specification information memory 103 is communicatively coupled to the processor 101. The specification information memory 103 stores the specification information SPEC of the rolling equipment installed in the rolling line and the rolled material processed by the rolling line. The specification information SPEC includes the position, angle, and size of the rolling equipment, the position, angle, and size of each machine constituting the rolling equipment, the end shape and size of the rolled material at each stage in the process, and other information that is not included in the rolling process information but is required for the generation of the three-dimensional visualization information described later. The specification information SPEC can be obtained via a network. In addition, the specification information memory 103 can also be built into the processor 101.

[0043] The communication module 104 is communicatively coupled to the processor 101. The communication module 104 is provided for communicating with an external device. The external device includes a data collection system 23 as an input source of rolling process information, and a three-dimensional animation display device 30 and an XR display device 40 as output destinations of three-dimensional visualization information described later. The user interface 105 is communicatively coupled to the processor 101. The user interface 105 is provided for the manager of the rolling line to input information. The specification information SPEC can also be registered by manual input of the manager via the user interface 105.

[0044] The three-dimensional animation display device 30 is a device for displaying three-dimensional visualization information described later by three-dimensional animation. The three-dimensional animation display device 30 is connected to the visualization device 11 by wire. However, the three-dimensional animation display device 30 can also be connected to the visualization device 11 wirelessly. In addition, the three-dimensional animation display device 30 can also be integrated with the visualization device 11.

[0045] The XR display device 40 is a device that displays three-dimensional visualization information described later by three-dimensional holography. The XR display device 40 is wirelessly connected to the wireless communication device 25 on the control network 24. The XR display device 40 communicates with the visualization device 11 via the wireless communication device 25. However, the XR display device 40 may also be connected to the visualization device 11 by wire.

[0046] 1-2. Functions of the visualization system of the first embodiment

[0047] use Figure 2 The functions of the visualization system 1 configured as described above will be described. Among the functions of the visualization system 1 described below, the functions of the visualization device 11 are functions implemented by reading the instruction INST from the program memory 102 and executing it by the processor 101 .

[0048] First, the visualization device 11 obtains the rolling process information INF01 from the control system 20 in real time. The visualization device 11 uses the rolling process information INF01 and the specification information SPEC to perform processing PRC01. Processing PRC01 is a process for generating three-dimensional visualization information INF02. The three-dimensional visualization information INF02 is information used to visualize the rolling equipment and the rolled material through three-dimensional representation. The three-dimensional visualization information INF02 is generated by editing and integrating the rolling process information INF01 based on the specification information SPEC. The three-dimensional visualization information INF02 includes three-dimensional movement information of the rolling equipment and the rolled material, and image information obtained by representing the one-dimensional information of the rolling equipment and the rolled material through images.

[0049] In addition, in the case of a machine that performs open-loop control, it is not possible to obtain feedback on its state from the rolling process information INF01. For such a machine, the state at each moment is estimated by interpolation calculation based on the assumed change amount or operation amount and the response characteristics such as the change speed of the actuator, assuming that the state is not abnormal. Then, the estimated value of the state is used to generate the three-dimensional visualization information INF02.

[0050] The visualization device 11 executes processing PRC02 for sending three-dimensional visualization information INF02. The three-dimensional visualization information INF02 is sent to the three-dimensional animation display device 30 and the XR display device 40 through processing PRC02. Processing PRC01 and processing PRC02 executed by the visualization device 11 can be executed by the same processor or by different processors. In addition, the visualization device 11 can also be composed of a device that executes processing PRC01 and a device that executes processing PRC02. The same is true for each process executed by the visualization device of the second to fourth embodiments described later.

[0051] The three-dimensional animation display device 30 generates and displays a three-dimensional animation ADS01 based on the three-dimensional visualization information INF02 by processing PRC11. The processing PRC11 uses the machine three-dimensional model MDL and the machine action definition information DEF. These are pre-stored in the memory of the three-dimensional animation display device 30. The machine three-dimensional model MDL is mechanical three-dimensional model information of the rolling equipment and the rolled material for three-dimensional display. The information used to make the machine three-dimensional model MDL move is the three-dimensional action information contained in the three-dimensional visualization information INF02. Then, the definition information indicating how each part of the machine three-dimensional model MDL moves based on the three-dimensional action information contained in the three-dimensional visualization information INF02 is the machine action definition information DEF. The three-dimensional action information contained in the three-dimensional visualization information INF02 can also be called information for making the machine three-dimensional model MDL move in accordance with the actual action of the rolling equipment, the actual action of the rolled material, and the shape change determined according to the rolling process information INF01. The three-dimensional visualization information INF02 is information that changes according to the rolling process information INF01, while the machine three-dimensional model MDL and the machine action definition information DEF are fixed information. However, when the rolling line that is the object is changed, the machine three-dimensional model MDL and the machine action definition information DEF are updated in a manner that reflects the changed content.

[0052] The three-dimensional animation display device 30 accepts the designation of the viewpoint VP from the user interface. In processing PRC11, a three-dimensional animation ADS01 is generated in which the machine three-dimensional model MDL is observed from the direction of the designated viewpoint VP. The manager can designate any viewpoint VP and monitor the movement and state of the rolling machine and the rolled material from various directions. In addition, when the three-dimensional animation display device 30 is integrated with the visualization device 11, the user interface 105 of the visualization device 11 can also be used to designate the viewpoint VP.

[0053] The XR display device 40 generates and displays a three-dimensional hologram HDS01 based on the three-dimensional visualization information INF02 by processing PRC21. The machine three-dimensional model MDL and the machine action definition information DEF are used to process PRC21. These are the same as those used in the three-dimensional animation display device 30 and are pre-stored in the memory of the XR display device 40. The generation of the three-dimensional hologram HDS01 uses, for example, a technology that displays images with different viewpoints in both eyes and visualizes them in three dimensions. According to the three-dimensional hologram HDS01, visual three-dimensional information can be freely obtained from the viewpoint of the wearer of the device.

[0054] 1-3. Three-dimensional Display by Visualization System of First Embodiment

[0055] use Figures 3 to 5The three-dimensional display performed by the visualization system 1 having the above-mentioned functions will be described by way of example. Figures 3 to 5 1 shows an example of a three-dimensional video ADS01 displayed by the three-dimensional video display device 30. The three-dimensional video ADS01 is converted into a hologram to form a three-dimensional hologram HDS01 of the XR display device 40.

[0056] Figure 3 1 is a diagram showing an example of a three-dimensional display of a rolling line. The visualization system 1 can be applied to a hot rolling line or a cold rolling line. Figure 3 The rolling line 200 illustrated in the figure is a hot rolling line. The screen of the three-dimensional animation display device 30 displays three-dimensionally the rolling equipment such as the heating furnace 210, the finishing mill 220, the roughing mill 230, the rod-shaped heater 240, the head cutter 250, the descaling device 260, the finishing mill 270, the discharge roller 280, and the down coiler 290 constituting the rolling line 200. For example, the first edge rolling mill E1, the first horizontal rolling stand R1, the second edge rolling mill E2, and the second horizontal rolling stand R2 are displayed three-dimensionally for the roughing mill 230. For example, seven rolling stands F1-F7 arranged in series are displayed three-dimensionally for the finishing mill 270. In addition, the rolled material 300 moving in the rolling line 200 is also displayed.

[0057] Through Figure 3 The entire rolling line 200 is three-dimensionally displayed as shown, so that the operation of each rolling equipment constituting the rolling line 200 and the conveying state of the rolled material 300 moving in the rolling line 200 can be easily grasped. In particular, the exemplified finishing mill 220, roughing mill 230, head cropping mill 250, finishing mill 270, discharge roller table 280, down coiler 290, and coil box not shown are visualized by three-dimensional expression, so that the state is easier to grasp than when it is represented by numerical values. The front and rear end positions, size, shape, camber, and vertical warping of the rolled material 300 can also be easily grasped by the three-dimensional display.

[0058] The three-dimensional display by the visualization system 1 can also be performed for each rolling equipment constituting the rolling line 200 . Figure 4 This is a diagram showing an example of a three-dimensional display of the first edger E1 and the first horizontal rolling stand R1 of the roughing mill 230, which is one of the rolling equipment. The left and right edger rollers 231L and 231R constituting the first edger E1 and the upper and lower horizontal rollers 232U and 232D constituting the first horizontal rolling stand R1 are displayed in three dimensions. In addition, a motor for driving the horizontal rollers 232U and 232D, a hydraulic cylinder for pressing the horizontal rollers 232U and 232D in the vertical direction, and a hydraulic cylinder for pressing the edger rollers 231L and 231R in the width direction can be added to the three-dimensional display.

[0059] The position, angle, shape, etc. of the rolled material 300 are depicted at each stage. Figure 4 In the example, the three-dimensional shapes of the rolled material 300A before being fed into the first edge rolling mill E1, the rolled material 300B being width-rolled by the first edge rolling mill E1, and the rolled material 300C after being horizontally rolled by the first horizontal rolling stand R1 are depicted. The end shape of the rolled material 300 in the middle of processing, specifically, the trimmed shape of the front and rear ends, is an element that is indispensable for depiction even though there is no measured value. Therefore, for example, by expanding and contracting a representative dimensional shape stored in advance according to the processing amount, the envisioned trimmed shape can be generated according to the processing amount. By using this method, the three-dimensional shape of the rolled material 300 being horizontally rolled by the first horizontal rolling stand R1 can also be depicted.

[0060] In addition, one-dimensional information of the roughing mill 230 that cannot be represented by three-dimensional motion is visualized by three-dimensional expression based on the image information. Figure 4 In the example, arrows obtained by three-dimensionally displaying the rolling loads PL and PR in the width direction acting on the first edge rolling mill E1 are displayed. In addition, arrows obtained by three-dimensionally displaying the rolling load PW in the vertical direction acting on the workpiece side of the first horizontal rolling stand R1 and the rolling load PD in the vertical direction acting on the driver side are displayed. The length, thickness, or color of each arrow indicates the magnitude of the rolling load.

[0061] By extracting the roughing mill 230 from the rolling line 200 and displaying it in detail in three dimensions, it is possible to more easily grasp the crown of the rolled material 300 during roughing rolling, for example. In addition, by three-dimensionally displaying images of the rolling loads PL and PR in the width direction acting on the first edge rolling mill E1 and the rolling loads PW and PD in the vertical direction acting on the first horizontal rolling stand R1, it is possible to easily grasp the state of the roughing mill 230. Then, by performing these three-dimensional displays in real time during the operation of the rolling line 200, reliable manual intervention in control can be achieved.

[0062] A detailed three-dimensional display can also be performed for rolling equipment other than the roughing mill 230. For example, when the finishing mill 270 is displayed in detail in three dimensions, the meandering of the rolled material 300 during the finishing rolling and the shape of the rolled material 300 after the finishing rolling can be more easily grasped. The thickness of the rolled material 300 during the finishing rolling and the change in the gap between the rolling rollers are relatively small, but by enlarging the finishing mill 270 and displaying it in three dimensions, their states can be visually grasped. In addition, when the finishing mill 270 is equipped with a slotting machine, its three-dimensional display can easily grasp the movement such as swinging. In the case of the down coiler 290, the three-dimensional display can make it easy to distinguish the four winding rollers around the core shaft, and it can be easy to identify the winding roller with abnormality.

[0063] The three-dimensional display based on the image information can also be applied to the three-dimensional display of one-dimensional information such as tension, rolling equipment, motor vibration, current, voltage, and motor temperature. If it is tension, its direction and size are expressed by the length and direction of the arrow. If it is vibration, current, voltage, or temperature, its size can be expressed by color. In the case where the three-dimensional visualization information includes image information, the three-dimensional animation display device 30 and the XR display device 40 use the pre-registered definition information to generate an image for three-dimensional display based on the image information. By combining the three-dimensional display based on the image information with the three-dimensional display based on the three-dimensional action information, the state of the rolling process can be grasped in more detail and easily. For example, when the discharge roller 280 detects a temperature abnormality of the motor, by changing the color of the motor detected to be abnormal, the motor with the temperature abnormality can be easily found from multiple motors.

[0064] The three-dimensional display by the visualization system 1 can also be enlarged so that the movement and shape changes of the rolled material 300 can be more clearly displayed. Figure 5 2 is a diagram showing an example of a three-dimensional display of a rolled material 300. Side guides 271W and 271D are provided at the entrance side of each rolling stand of the finishing mill 270. In the finishing mill 270, the rolled material 300 often enters the rolling stand at a high speed. Therefore, the opening of the side guides 271W and 271D is set to a width after adding a margin to the width of the rolled material 300 in advance. Figure 5 In FIG. 1 , the rolled material 300 passing between the side guides 271W and 271D is shown from a viewpoint directly above.

[0065] The tail end 301 of the rolled material 300 is contracted, but it is difficult to obtain the actual measured value of the size and shape of the contraction. Therefore, for example, when a collision with the side guides 271W and 271D is detected, the shape change of the tail end 301 is assumed based on which of the two side guides 271W and 271D the rolled material 300 has collided with and the collision position of the rolled material 300. The shape change includes the case where the tail end 301 is cut or bent due to the collision. Figure 5 3 shows a situation in which the rear end 301 of the rolled material 300 bends toward the side guide 271W and collides with it.

[0066] 1-4. Effects of the visualization system of the first embodiment

[0067] According to the visualization system 1, three-dimensional visualization information is generated based on real-time rolling process information obtained from the rolling line. The manager who manages the rolling line can grasp the state of the rolling process in detail and easily based on the three-dimensional visualization information displayed by the three-dimensional display device. As a result, the maintenance of the equipment is improved, the product quality is improved, and the yield rate is improved.

[0068] 2. Second Implementation

[0069] 2-1. Configuration of visualization system according to second embodiment

[0070] use Figure 6 The configuration of a visualization system according to a second embodiment of the present invention will be described. The visualization system 2 according to this embodiment is different from the visualization system 1 according to the first embodiment in the configuration of a visualization device that visualizes rolling process information.

[0071] The visualization device 12 constituting the visualization system 2 includes, in addition to the processor 101, the program memory 102, the specification information memory 103, the communication module 104, and the user interface 105, an information storage 106. The elements other than the information storage 106 are the same as those of the visualization device 11 of the first embodiment, and thus the description thereof is omitted. However, in order to realize the functions unique to the present embodiment described later, the contents of the instructions INST of the present embodiment stored in the program memory 102 are different from those of the instructions INST of the first embodiment.

[0072] The information storage 106 is coupled to the processor 101 so as to be communicable. The information storage 106 stores the three-dimensional visualization information output to the three-dimensional animation display device 30 and the XR display device 40. A database for managing the three-dimensional visualization information is constructed in the information storage 106. By managing the date and time when the three-dimensional visualization information is recorded in the information storage 106 in the database, the three-dimensional visualization information from any time in the past can be read from the information storage 106. In addition, the information storage 106 can also be built into the visualization device 12 or installed separately in the visualization device 12.

[0073] 2-2. Functions of the visualization system of the second embodiment

[0074] use Figures 7 to 12 The functions of the visualization system 2 configured as described above will be described. However, the description of the same processing as that performed by the visualization system 1 of the first embodiment will be omitted or simplified. In addition, the description of the same information as that used in the visualization system 1 of the first embodiment will also be omitted or simplified. Among the functions of the visualization system 2 described below, the functions of the visualization device 12 are functions implemented by reading the instruction INST of this embodiment from the program memory 102 and executing it by the processor 101.

[0075] Figure 7 The first function of the visualization system 2, i.e., the real-time display function of the three-dimensional visualization information, is shown. The visualization device 12 generates the three-dimensional visualization information INF02 using the rolling process information INF01 and the specification information SPEC obtained in real time from the control system 20. Then, the visualization device 12 sends the three-dimensional visualization information INF02 to the three-dimensional animation display device 30 and the XR display device 40, and stores all the generated three-dimensional visualization information INF02 in the information storage 106.

[0076] The processing executed by the three-dimensional animation display device 30 and the XR display device 40 in response to the input of the three-dimensional visualization information INF02 is the same as that in the case of the visualization system 1 .

[0077] Figure 8The second function of the visualization system 2, i.e., the reproduction and display function of the past three-dimensional visualization information, is represented. The visualization device 12 receives the input of the specified period PBP and the input of the specified speed PBS, and executes the processing PRC03 according to the specified period PBP and the specified speed PBS. The input of the specified period PBP and the specified speed PBS uses the user interface 105. The processing PRC03 is a processing of reading the three-dimensional visualization information INF03 corresponding to the specified period PBP from the information storage 106 and reproducing it at the specified speed PBS. The specified period PBP is determined according to the reproduction start time and the reproduction end time. However, it is also possible to start the reproduction by specifying only the reproduction start time and end the reproduction at any time after the reproduction starts. The visualization device 12 executes the processing PRC02 and sends the three-dimensional visualization information INF03 to the three-dimensional animation display device 30 and the XR display device 40.

[0078] The 3D animation display device 30 generates and displays a 3D animation ADS02 based on the 3D visualization information INF03 by processing PRC11. The 3D animation ADS02 is displayed at a specified speed PBS over a specified period PBP. The XR display device 40 generates and displays a 3D hologram HDS02 based on the 3D visualization information INF03 by processing PRC21.

In parallel with the display of the three-dimensional animation ADS01, the three-dimensional visualization information INF02 that will be the basis of the three-dimensional animation ADS01 is stored in the information storage 106. The manager can grasp the state of the rolling process through the three-dimensional animation ADS01 displayed in real time.

[0080] After the three-dimensional animation ADS01 is finished, the manager may want to confirm a certain scene again. In this case, the manager operates the user interface 105 of the visualization device 12 and inputs the period that he wants to confirm as the specified period PBP. Fig. 9 In the example shown, the period from time t1 to time t2 is input as the specified period PBP. In addition, the administrator can also input the specified speed PBS by operating the user interface 105 of the visualization device 12. The specified speed PBS is normally set to a constant speed.

[0081] The three-dimensional visualization information INF03 corresponding to the designated period PBP is read from the information storage 106 and reproduced at the designated speed PBS. The manager can reconfirm the state of the rolling process by displaying the three-dimensional animation ADS02 generated based on the three-dimensional visualization information INF03.

[0082] exist Fig. 9 In the figure, from the top, the reproduction period of the three-dimensional animation ADS02 when the specified speed PBS is a constant speed (×1.0), the reproduction period of the three-dimensional animation ADS02 when the specified speed PBS is 0.5 times the speed (×0.5), and the reproduction period of the three-dimensional animation ADS02 when the specified speed PBS is 2 times the speed (×2.0) are shown. In this way, the specified speed PBS can be made faster or slower than the constant speed. In addition, the reproduction period of the three-dimensional animation ADS02 when the specified speed PBS is made variable in the order of 2 times the speed, 0.5 times the speed, and constant speed is shown in the bottom section. In this way, by changing the specified speed PBS, the overall reproduction time can be suppressed while carefully observing the scene of interest.

The visualization device 12 performs processing PRC01 on the rolling process information INF01 obtained in real time from the control system 20, and generates three-dimensional visualization information INF02 using the rolling process information INF01 and the specification information SPEC. In parallel with the processing PRC01, the visualization device 12 receives the input of the specified period PBP and performs processing PRC03, and reads the three-dimensional visualization information INF03 corresponding to the specified period PBP from the information storage 106. In addition, when using the simultaneous display function, the specified speed PBS of the three-dimensional visualization information INF03 is fixed at a constant speed. The visualization device 12 performs processing PRC02 and sends the three-dimensional visualization information INF02 and the three-dimensional visualization information INF03 to the three-dimensional animation display device 30 and the XR display device 40.

[0084] The 3D animation display device 30 generates a 3D animation ADS01 according to the 3D visualization information INF02 by processing PRC11, and generates a 3D animation ADS02 according to the 3D visualization information INF03. The XR display device 40 generates a 3D hologram HDS01 according to the 3D visualization information INF02 by processing PRC21, and generates a 3D hologram HDS02 according to the 3D visualization information INF03.

[0085] Fig.11 as well as Fig.122 is a diagram showing an example of a display method of a three-dimensional animation by the simultaneous display function of the visualization system 2. Fig.11 In the first display mode shown, the three-dimensional animation display device 30 displays the three-dimensional animation ADS01 and the three-dimensional animation ADS02 side by side. The three-dimensional animation ADS01 shows the movement of the upper and lower rolling rollers 272U and 272D and the state of the rolled material 300 at the current moment. The three-dimensional animation ADS02 shows the movement of the upper and lower rolling rollers 272U and 272D and the state of the rolled material 300 at a specified moment in the past. By comparing and observing the three-dimensional animation ADS01 and the three-dimensional animation ADS02, the manager can easily grasp the changes in the movement of the rolling rollers 272U and 272D and the changes in the state of the rolled material 300. In addition, the display screen displaying the three-dimensional animation ADS01 and the display screen displaying the three-dimensional animation ADS02 can also be different screens.

[0086] exist Fig.12 In the second display mode shown, the three-dimensional animation display device 30 displays the three-dimensional animation ADS02 overlapping with the three-dimensional animation ADS01. Fig.12 In the figure, the three-dimensional animation ADS01 is indicated by a dotted line, and the three-dimensional animation ADS02 is indicated by a solid line. By superimposing the three-dimensional animation ADS02 on the three-dimensional animation ADS01, the manager can more easily grasp the changes in the movements of the rolling rolls 272U and 272D and the changes in the state of the rolled material 300.

As a result, the accuracy of the obstacle analysis is improved, which leads to the improvement of product quality. In addition, all the generated three-dimensional visualization information is stored in the information storage device 107, so multiple three-dimensional visualization information at different times can be displayed in parallel or overlapping.
