The embodiment of the invention provides a motion process display method based on a digital twin technology, which is applied to a display platform, wherein the display platform is in communication connection with a plurality of devices, the devices send motion state data of each section of preset interval distance starting time to the display platform according to the preset interval distance when in motion, and the motion state data are used for simulating a motion process of the display platform.
Specifically, for each device, before the device starts to move, the motion process of the device is divided into a plurality of small segments by utilizing the principle of infinitesimal division, namely, each segment is preset with a spacing distance, the device can be moved in a large range to be divided into a plurality of small segments by the method, and the division mode can enable the motion of each small segment to be controllable relative to the motion condition of a whole segment for a plurality of hours.
The motion state data may include a starting position coordinate of the device when the device moves at each preset interval distance, a moving time of the device, and a plurality of motion speed values, such as a fastest motion speed, a lowest motion speed, and the like. Specifically, the more motion state data is acquired, the more realistic the simulation of the motion process of the device is exhibited. In the embodiment of the invention, the acquired motion state data is not required to be specifically selected according to actual requirements.
The device may send the corresponding motion state data to the corresponding presentation platform via the TCP protocol.
In the embodiment of the invention, an intelligent optical fiber display system is used as a display platform; the moving process of a plurality of mechanical arms of the intelligent optical distribution equipment is used as the moving process in the equipment.
As shown in fig. 1, the method comprises the steps of:
step S101: and sending a motion instruction to target equipment for displaying the motion process. Specifically, the smart fiber display system sends the relevant movement command to the robotic arm.
Step S102: and when the target equipment starts to move, performing simulation display of a movement process according to the acquired movement state data of the target equipment.
Specifically, when the mechanical arm starts to move, uploading corresponding movement state data such as the starting coordinate of the physical position of movement, the movement time of the physical equipment and the like to the intelligent optical fiber display system through a TCP protocol; the intelligent optical fiber display system performs simulation display on the motion process of the mechanical arm according to the received motion state data.
According to the motion process display method based on the digital twin technology, which is provided by the embodiment of the invention, the operation condition of the transmission equipment is monitored without collecting video stream hardware equipment and consuming a large amount of network bandwidth, the analog display of the motion process of the equipment is directly realized through the communication connection between the display platform and the equipment and based on the digital twin technology, so that the hardware equipment resources are reduced, and the analog display of the motion process of the equipment is not influenced; the motion distance of the equipment is divided into sections by utilizing the principle of micro-element division, so that the motion of each small section is controllable, the data transmission quantity is small, and the motion process of the display equipment can be simulated in real time.
As an optional implementation manner of the embodiment of the present invention, step S102 includes: when the target equipment moves at a uniform speed, acquiring the current network time delay and the first movement time of the target equipment within a first section of preset interval distance; determining the simulation lag time of the display platform according to the network time delay and the first motion time; determining a waiting display time delay according to preset conditions, and determining the starting time of the display platform for displaying the motion process of the target equipment according to the simulation lag time and the waiting display time delay, wherein the waiting display time delay reflects the time difference between the time of the display platform receiving the motion state data of the target equipment and the time of the display platform for displaying the motion process of the target equipment; and performing simulation display of a motion process according to the starting time and the acquired motion state data of the target equipment.
Specifically, the mechanical arm is to move from the start port A to the destination port Z with a distance S total The method comprises the steps of carrying out a first treatment on the surface of the Before the mechanical arm starts to move, dividing the movement distance S of the mechanical arm into N sections, and obtaining the distance of each section:
S＝S total /N
the larger N is, the more the number of the divided moving segments is, the more the restored object moves truly under the variable speed movement, but the conveying amount is relatively larger. The smaller N is, the less the divided moving segments are, the more the movement of the restoring object is blurred under the variable speed movement, but the transmission amount is relatively smaller. In the embodiment of the invention, the value of N is not particularly limited, and the N is determined according to actual requirements.
After dividing the movement distance S of the mechanical arm into N sections, the mechanical arm starts to move at a uniform speed and passes through a first section of preset interval distance (from a start port A to a next section of start port B), and at the moment, the current network time delay delta is obtained t1 And a first movement time within the start port a to the next segment start port B:
t m1 ＝S AB /V AB
wherein: s is S AB Representing a first segment of preset spacing distance; v (V) AB Indicating that the mechanical arm is at S AB An average speed of movement within; network delay delta t1 The method can be obtained according to the current heartbeat package test;
when the mechanical arm moves to the next segment starting port B, the network delay delta is passed t1 Transmitting the motion state data in the first section of preset interval distance to a corresponding intelligent optical fiber display system, namely, the corresponding simulation lag time when the intelligent optical fiber display system performs simulation display on the motion process of the mechanical arm is as follows:
t d ＝t m1 +δ t1
after the intelligent optical fiber display system receives the motion state data, the motion state data is analyzed and passes through delta t2 After a time delay (waiting for display time delay), the motion process in the first section of the preset interval distance of the mechanical arm is simulated and displayed, so thatAfter the intelligent optical fiber display system finishes displaying the movement process in the first section of the preset interval distance of the mechanical arm, the intelligent optical fiber display system already receives the movement state data in the next section of the preset interval distance and starts to simulate and display the movement process in the next section of the preset interval distance, so that the movement process of the mechanical arm can be simulated and displayed truly and continuously. By the method, the transmission delay of the following network instability can be counteracted, and the situations of blocking and the like caused by the network delay instability and the like can be reduced.
Namely, the starting time of the intelligent optical fiber display system for displaying the movement process of the mechanical arm is as follows:
t d ＝t m1 +δ t1 +δ t2
wherein the network delay delta t1 The prediction can be performed according to a neural network, and the currently better models are an Elman neural network model and an AR model. Waiting for presentation of the delay delta t2 Can be based on the current network environment delta t1 The adjustment is, for example, that the network environment is relatively stable for a period of time, i.e. the network delay is in a relatively stable stage no matter the network environment is good or the network environment is bad, and the waiting exhibits a delay delta t2 Can be set to a relatively small value; if the network environment changes from a poor environment such as congestion to a better environment for a period of time, then the waiting time exhibits a delay delta t2 A relatively small value may also be set; if the network delay jitter is relatively large and is changed from a better environment to a more congested environment for a period of time, the waiting presentation delay delta needs to be increased appropriately t2 。
When the starting time is met, the intelligent optical fiber display system can simulate and display the movement process of the mechanical arm according to the acquired movement state data of the mechanical arm.
As an optional implementation manner of the embodiment of the present invention, step S102 further includes: when the target equipment moves in a variable speed manner, determining the total time delay of the target equipment in the moving process and the second moving time corresponding to the target equipment in each preset interval distance; determining the starting time of the display platform for displaying the motion process of the target equipment according to the total time delay and the second motion time; and performing simulation display of a motion process according to the starting time and the acquired motion state data of the target equipment.
Specifically, after dividing the movement distance S of the mechanical arm into N segments, the mechanical arm performs a variable speed movement in the process of moving.
When n=2, the movement time of the mechanical arm is as follows when the mechanical arm moves to the next segment start port B and from the port B to the next segment start port C:
t m2 ＝S BC /V BC
wherein t is m2 Representing the movement time of the mechanical arm from port B to the next segment start port C; s is S BC Representing the distance of movement of the robotic arm from port B to the next segment start port C; v (V) BC The average movement speed of the mechanical arm from the port B to the next segment starting port C can be calculated according to a plurality of speed values such as the maximum acceleration, the minimum acceleration and the like in the movement state data;
when the mechanical arm moves from port B to the next segment start port C, a delay delta is passed t3 The corresponding motion state data is transmitted to a corresponding intelligent optical fiber display system (total time delay), namely, the corresponding starting time when the intelligent optical fiber display system performs simulation display on the motion process of the mechanical arm is as follows:
t x ＝t m1 +t m2 +δ t3
when the starting time is met, the intelligent optical fiber display system can simulate and display the movement process of the mechanical arm according to the acquired movement state data of the mechanical arm.
When the intelligent optical fiber display system displays the nth segment information, the mechanical arm sends the (n+1) th segment information to the intelligent optical fiber display system, namely:
S AB /V AB +δ t1 +δ t2 ＞S BC /V BC +δ t3
wherein S is AB ＝S BC ＝S total /N
In the moving process of the mechanical arm of the intelligent optical distribution equipment, the movement of the mechanical arm can be regarded as uniform. Then there are:
δ t1 +δ t2 ＞δ t3
wherein the total delay delta of the network t3 The prediction may be performed based on a neural network model. Such as using an Elman neural network model or an AR model. According to delta t3 The estimated value is used for adjusting the waiting display time delay delta t2 。
For variable speed motion, the solution can be substituted by the highest and lowest instantaneous speeds as average speeds during the overall motion. In general, δt2 can be appropriately reduced in the case of a relative acceleration motion. For the case of the relative deceleration movement, δt2 may be appropriately increased. In general, the platform latency delta is appropriately increased t2 The platform display motion is smoother, the clamping is not easy to occur, and the motion of the platform display motion is more lagging relative to that of real equipment. Setting delta t2 When the value is obtained, the processing can be balanced according to the requirement.
As an optional implementation manner of the embodiment of the present invention, before step S102, the method further includes: and obtaining physical parameters of the display platform and modeling the appearance of the target equipment by using a preset engine.
Specifically, in the intelligent optical fiber display system, the physical parameters may include a device model, the number of fiber core ports, a movement mode of a mechanical arm corresponding to the fiber core ports, a battery power, an operation state, and the like. The number of fiber core ports is different, so that the movement modes of the mechanical arms are also different;
the preset engine may be a Web 3D digital drawing engine. The intelligent optical fiber display system can complete appearance modeling of the mechanical arm through the Web 3D digital drawing engine, so that the motion process of the mechanical arm can be subjected to appearance simulation in a digital space.
As an optional implementation manner of the embodiment of the present invention, the simulation display of the motion process according to the start time and the acquired motion state data of the target device includes: calling a corresponding interface according to the physical parameter and the motion instruction; mapping the motion state data of the target equipment into the preset engine and responding to the simulation display operation of the motion process of the target equipment through the interface.
Specifically, after the intelligent optical fiber display system collects the physical parameters, the relevant web 3D API can be called according to the motion instruction; after the motion state data of the mechanical arm are mapped into the corresponding Web 3D digital drawing engine, the intelligent optical fiber display system can complete dynamic display of the cluster transverse of the motion of the mechanical arm by calling the Web 3D API.
As an optional implementation manner of the embodiment of the present invention, the method further includes: when the motion state data of the target equipment is obtained, a preset confirmation frame is sent to the target equipment, so that the target equipment responds to the deletion operation of the motion state data in a sending queue according to the preset confirmation frame, and the sending queue stores the motion state data when each preset interval distance sent to the display platform by the target equipment is started.
Specifically, the transmission of the motion state data of each section of preset interval distance between the target equipment and the display platform adopts an ACK confirmation mechanism.
After receiving the motion state data uploaded by the target equipment, the display platform sends an ACK (acknowledgement) frame to the target equipment; after receiving the ACK confirmation frame, the target device deletes the corresponding motion state data in the transmission queue, and in this way, the motion state data in each section of preset interval distance can be ensured not to be missed.
If the N-th motion state data is executed by the display platform, the following n+1th motion state data arrives, and the display platform judges that all motion state data before the n+1th motion state data are received, the motion state data are received under normal conditions, and the motion state data which are not received possibly exist before under extreme abnormal conditions. At this time, the platform needs to wait for the N pieces of previous motion state data to be received, and the display platform responds to the (n+1) th ACK acknowledgement message. When the device receives the n+1th ACK acknowledgement frame, all previous motion state data is deleted from the transmit queue. This reduces the amount of acknowledgement information transmitted; if the motion state data which is not received is within the safe network time delay threshold value, waiting; if the receiving time corresponding to the motion state data which is not received exceeds the safe network delay threshold, initiating a request frame of the motion state data which is overtime and resends by the display platform.
In an extreme case, the display platform may also get stuck, for example, the network suddenly becomes worse from a normal state, the network delay increases in geometric multiple, and the network is disconnected in a limit case, where the display platform determines whether to receive the motion state data according to a time threshold or senses whether to disconnect the network according to a heartbeat packet.
