DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Please refer to the instruction manual Figures 1 to 7 , an embodiment provided by the present invention: an integrated production line integration and simulation system based on a magnetic levitation transport line, comprising: The module free assembly and construction unit includes: standardized processing of the maglev line module model library, grid placement module and common maglev transport line layout; The standardized processing of the above-mentioned magnetic levitation line module model library is to simplify the internal structure of the .step format 3D magnetic levitation line module model and its mover model, and then convert them into a .fbx format model, and then through unified formatting processing, convert the .fbx model into a reusable standard prefabricated body as a resource model of the model library. The 3D magnetic levitation line module model and its mover model are configured to generate a whole line model of a specified length.

[0019] The module free assembly building unit also implements a grid placement module. The implementation principle is to establish a grid in three-dimensional space. The grid cells contain their coordinate information and internal model information. The cell size is adapted to the minimum module of different types of modules. Users can configure and obtain the required line model in the model library, select the appropriate rotation direction and place it in the grid. The system will check whether there is a model in the grid, so as to determine whether the operation of placing the model is legal; The module free assembly construction unit also realizes the function of one-click generation based on the configuration information set by the user obtained by the magnetic levitation configuration information analysis unit, mainly including the common bilateral connecting line layout and ring line layout in the transportation line. The transportation line generated with one click can have different line lengths to meet the requirements of most on-site automated production lines. The implementation principle is to calculate the number of grid cells occupied by the entire line model and the position of the line in the magnetic levitation transportation line to obtain the coordinates in the grid, so as to automatically place all the lines in the correct position of the grid.

[0020] The integrated system also includes a magnetic suspension configuration information analysis unit, which is used to obtain the configuration information of the external controller, analyze the system configuration, line configuration, station configuration, mover configuration, single-axis servo configuration, docking configuration and station motion configuration in the configuration information, and generate the construction layout of the magnetic suspension transport line and the mover station motion process flow. The implementation principle is to first obtain the external controller configuration information. The configuration information is a set of .json format configuration files filled in and generated by the host computer software of the external controller. The system provides two ways to obtain files. One is to directly copy the files in the path where the host computer stores the configuration information; the other is that when the user needs to use the configuration files stored in other paths of the computer, the corresponding folder can be directly selected through the pop-up window; Next, the configuration information is analyzed to obtain the attributes related to the model, including analyzing the line configuration information to obtain the layout of the line, analyzing the mover configuration information to obtain the number and initial position of the movers, analyzing the station configuration information to obtain the allocation and processing details of the station on the line, analyzing the single-axis servo configuration information to obtain the layout and motion parameters of the single axis, analyzing the docking configuration information to obtain the ferrying motion details and the timing of docking, and analyzing the station motion configuration information to obtain the mover station motion process. Then, the analysis results are combined with the system's form page to reorganize the configuration information of the three-dimensional maglev transport line and save it in a .json format file. The unit also has the function of memorizing the most recent transport line configuration information, and can load the memorized configuration information with one click.

[0021] The integrated system also includes a maglev transport line production operation process simulation unit. According to the mover station motion process flow generated by the maglev configuration information analysis unit, the transport line equipment model motion program is given to the three-dimensional maglev module free assembly construction unit to simulate the operation status of the production line without on-site equipment. The implementation principle is to establish a control logic based on the mover, single-axis servo, line body, station and transport line to simulate the control logic of the external controller, and continuously send motion instructions to the mover and single-axis servo according to the production line operation process requirements to determine whether the motion conditions are met. After the motion instruction is successfully sent, the mover and the single axis move in coordination, thereby completing the complete production line operation process. The above-mentioned movement conditions mainly include whether the mover is at the designated workstation, whether the process at the workstation is completed, whether the connecting line is in place, and whether the mover at the next workstation has left.

[0022] The integrated system also includes a production line operation process sequence and CT analysis unit, which is used to record the motion state and time information of the mover when the production operation process simulation unit of the magnetic levitation transport line is running, analyze the station motion sequence, and intercept the process CT of the entire production line; Since the maglev transport line usually undertakes the work of transporting workpieces on site, the workpieces will continuously pass through designated workstations for processing and other processes. There are entrances and exits on the entire transport line. The entrance is connected to the exit of the previous processing equipment, and the exit is connected to the entrance of the next processing equipment. Each equipment is linked together. Therefore, the time when the workpiece enters and leaves the maglev transport line, that is, the process CT, affects the processing efficiency of the entire automated production line. The result of the process CT is determined by the time difference from the workpiece leaving the current workstation to the next workstation for processing, that is, the workstation movement sequence. Therefore, timing and CT analysis are crucial in the production and operation planning process of the transport line.

[0023] The production line operation process sequence and CT analysis unit uses the transportation line production operation process simulation unit to realize the same processing environment as the on-site in the software, simulate the complete production line operation process, obtain the workstation movement sequence in the dynamic three-dimensional production line operation environment, and calculate the process CT; if the CT does not meet the actual needs, after adjusting the workstation movement sequence, re-simulate and test the CT until it meets the needs; The process CT is the time difference between the time when each workpiece enters the production line and the time when each workpiece leaves the production line. The station movement sequence is the time difference between the time when each workpiece leaves the current station and the time when it leaves the next station. The above-mentioned means of adjusting the timing of workstation movement mainly include modifying the speed, acceleration and deceleration of the mover movement, modifying the speed, acceleration and deceleration of the connecting line body ferry, modifying the position distribution of the workstation and modifying the number of movers, etc. If the modified speed parameter reaches the limit value of the equipment, and the reasonable design of the workstation and mover distribution still cannot meet the process CT requirements, it means that the production line process requirements cannot be met and the plan needs to be redesigned; The integrated system also includes a solution generation unit, which plans the process layout of the transportation line according to the three-dimensional magnetic suspension module free assembly construction unit, uses the magnetic suspension transportation line production operation process simulation unit to design the production line operation process flow, realizes the dynamic motion simulation of the transportation line, and then calculates the process CT and station motion timing through the production line operation process timing and CT analysis unit to generate a complete 3D solution; Through the three-dimensional magnetic levitation module free assembly and construction unit, the magnetic levitation configuration information analysis unit, the magnetic levitation transportation line production operation process simulation unit and the production line operation process timing and CT analysis unit, we design and generate magnetic levitation transportation line solutions for customers. The solution includes the layout of the line, the configuration of the workstations and movers, the production line operation process flow, the workstation movement timing and process CT results and 3D dynamic simulation animation, which is convenient for users to communicate their needs with the business personnel of the magnetic levitation transportation line. The three-dimensional simulation results intuitively and clearly show the operation effect of the production line, accelerating the efficiency of the production line.

[0024] The integrated system also includes an online monitoring unit for the maglev transport line, which can communicate with the actual integrated production line to obtain the motion status of the mover and the single-axis servo, that is, to obtain the real-time motion status information of the mover and the single-axis servo, and then use the data to drive the 3D model, so as to realize real-time monitoring of the maglev equipment; The communication methods with the actual integrated production line include: Connect via Ethernet port: use TCP / IP network request to obtain data; Through memory sharing: get the data stored in the memory of the external controller; The implementation principle is to first obtain the motion information of the mover and the single axis in the external controller. There are two ways to obtain it. One is that the system sends a request to the external controller through TCP / IP communication and receives feedback information; the other is to install the system in the industrial computer where the external controller is located through memory sharing. The external controller saves the data in the specified memory, and the system obtains the data from the specified memory, then processes the data and maps it to the virtual magnetic levitation device.

[0025] The integrated system also includes a standard laboratory unit. The standard laboratory provides equipment layouts used by maglev transport line R&D personnel in daily development and equipment layouts used for display and training to customers, namely standard layouts, including standard maglev shuttle transport lines and standard maglev ring transport line layouts, to help production line staff and maglev technicians understand and become familiar with the meaning of various attributes in the configuration, production line operation process flow and online debugging process. The implementation principle is to use the maglev configuration information analysis unit to analyze the configuration information obtained from the host computer, and then verify whether the configuration information meets the configuration standards of the standard laboratory equipment. If it meets the requirements, the three-dimensional maglev module free assembly and construction unit is used to generate a virtual maglev transport line model of this layout; then, when there is no equipment, the maglev transport line production operation process simulation unit and the production line operation process timing and CT analysis unit are used to design the production line operation process and generate a maglev transport line solution; finally, when there is equipment, the maglev transport line online monitoring unit is used to monitor the actual maglev transport line in real time and debug the equipment.

[0026] The integrated system also includes a graphics interaction and viewing angle operation unit, which includes: Perspective operation module: Combined with human-computer interaction external devices, the observation perspective can be adjusted as needed with the first-person lens; Graphical interactive page: displays the interactive entrances to different units, including the interactive entrance to the transport line construction unit, the interactive entrance to the solution generation unit, and the interactive entrance to the standard laboratory unit. It uses distributed function windows and prompts to guide users to operate and configure correctly. It can realize intuitive and simple graphic interactive pages and use external devices to control the display perspective of various models in the 3D view. The principle of perspective control is to first design the starting point of the first-person perspective, and then set the camera to follow the protagonist. By controlling the position of the protagonist, the camera's perspective can be changed. The position of the protagonist can be controlled including forward and backward, left and right rotation, zooming in and out, rising and falling, and pitching. External devices include mouse and keyboard.

[0027] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
