Description

Technical Field

[0001] This invention relates to the field of satellite automated assembly system technology, and more specifically, to a method for information interaction between a satellite automated assembly system and a MES system. Background Technology

[0002] With the booming development of commercial spaceflight, traditional manual methods of satellite assembly and quality control can no longer meet the production needs of mass-produced satellites at low cost and high efficiency.

[0003] In recent years, with the implementation of domestic satellite constellation construction, satellite automated assembly technology and informatization have developed rapidly. In satellite automated assembly systems, automatic control technology is one of the core technologies for achieving batch automated assembly and quality tracking. Regarding informatization, most systems utilize Manufacturing Execution System (MES) to digitally manage information such as production tasks, processes, materials, logistics, quality, and process records. Therefore, in actual production, it is necessary to solve the information interaction problem between the automatic control system and the MES system in the satellite automated assembly system, break down information silos between various stages of satellite batch manufacturing, and achieve seamless connection between the planning layer, execution layer, and the field to ensure the smooth progress of production tasks.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Summary of the Invention

[0005] The purpose of this invention is to provide an information interaction method between a satellite automatic assembly system and a MES system, which enables automated assembly and information management of satellite products.

[0006] This invention provides an information interaction method between a satellite automatic assembly system and a MES system, including an automatic assembly system, wherein the automatic assembly system includes an automatic control system, and a PLC central control system and a host computer system are configured on the automatic control system;

[0007] The PLC central control system is integrated with the mechanism in the automated assembly system to achieve motion control; the host computer system interfaces with the MES system to achieve information exchange of production task information, material logistics information, automated assembly process information, and assembly quality information.

[0008] Specifically, the following steps are included:

[0009] S1: The MES system sends the production plan information to the host computer system. After receiving the information, the host computer system scans the satellite product information of its workstation and feeds back the information obtained from the scan to the MES system for verification of production task information.

[0010] S2: Once the production task information is verified to be correct, the MES system will send the corresponding running program information to the host computer system, which will then send the program information to the PLC control system to implement the production action control of the automatic assembly system.

[0011] S3: Before the assembly action is executed, the automatic assembly system automatically determines whether materials need to be delivered based on the material information in the trays on the workstation. If so, the demand information is fed back to the MES system, which then automatically calls for material delivery. After delivery, the host computer system controls the automatic assembly system to scan the tray information and call the MES system interface to obtain the material information. The final assembly process is then scanned.

[0012] S4: The automated assembly system receives the production task number and confirms the start-up information with the MES system before starting work by running the automated program;

[0013] S5: The host computer system tracks and monitors the operation of the automatic assembly system program and the status of production tasks, and feeds back program abnormalities and task completion status information to the MES system; if a program abnormality occurs, the MES system will call technical personnel to handle the abnormality; if the task is completed, the MES system will issue the next production task.

[0014] Further, step S5 includes:

[0015] S51: During the production process, the automated assembly system scans and obtains the consumed materials, and feeds the information back to the MES system through the host computer system. The MES system verifies and records the material consumption.

[0016] S52: During the production process, the automated assembly system feeds back program error information and product defect information to the MES system through the host computer system. The MES system then calls on technicians to handle the error.

[0017] S53: After the automatic assembly system completes a certain process, it uploads the completion information and quality control information during the process to the MES system through the host computer system. After verification, the MES system triggers the start signal of the next process and feeds the signal back to the host computer system. The host computer system then transmits the signal to the PLM central control system to prepare for the start of the next process.

[0018] Furthermore, in step S3, the start-up confirmation information is transmitted from the host computer to the MES system. After the MES system confirms that there are no errors, it feeds back the start-up information to the host computer system, which then transmits it to the PLC control system. The PLC control system then starts running the program and starts production according to the set parameters.

[0019] Further, step S1 includes:

[0020] S11: The MES system sends the production task number to the automated assembly system at the workstation based on the production schedule and the on / off status of the automated assembly system.

[0021] S12: After receiving the task, the automated assembly system scans the satellite SN number at the workstation to obtain information such as satellite product information and production status bound to the SN number.

[0022] S13: MES provides an SN verification interface to verify the SN information. If there is a problem with the verification, the MES system will send the error information back to the automated assembly system, issue an anomaly warning, and call the technical personnel to handle the anomaly.

[0023] Furthermore, in step S13, the SN information is verified. The verification includes whether there are any unfinished processes at the current workstation for the product SN, whether the current status of the whole star SN is qualified, and whether the order status corresponding to the whole star SN allows production.

[0024] Further, step S2 includes:

[0025] S21: After the SN number is verified to be correct, the MES system will send the process execution program number corresponding to the task order number back to the automated assembly system.

[0026] S22: After receiving the program number, the automatic assembly system loads the process execution program by the PLC central control system.

[0027] Further, step S3 includes:

[0028] S31: Before the process execution program runs, the automatic assembly system needs to scan the pallet information to confirm the material delivery status;

[0029] S32: If materials need to be delivered, the MES system will make a material call, and then the warehousing and logistics system will deliver the materials and pallets to the workstation according to the final assembly task.

[0030] S33: After delivery, the automated assembly system scans the pallet information again and calls the MES system interface to verify the pallet and material information. After verification, the process program is executed.

[0031] S34: If no materials are needed, start the process procedure directly.

[0032] Furthermore, step S5 also includes: after the materials arrive, the automatic assembly system starts to execute the automatic assembly process; the MES system obtains the completion information of the process at the workstation through automatic process interaction information, and judges the completion information. If all processes are completed, the next production task is issued; if there are still processes to be executed, the automatic assembly process continues to be executed.

[0033] Further, step S4 includes:

[0034] S41: When the automated assembly system is performing the automated assembly process, it simultaneously sends a work order request signal to the MES system.

[0035] S42: After receiving the work order request information, MES performs work order start verification. If there is a problem with the verification, the MES system will send the error information to the automated assembly system, the system will issue an exception warning, and the MES system will call the technicians to handle the exception. If the verification passes, work can start.

[0036] S43: If the MES system verifies the work order start-up, it will process the work order start-up and send the verification success information back to the automation equipment system.

[0037] S44: After receiving the work order inspection success information from the MES system, the automated assembly system automatically performs process execution according to the processing procedure requirements.

[0038] Further, step S51 includes:

[0039] S511: The automated assembly system scans the material information and serial number of the product to be installed and transmits the information to the MES system;

[0040] S512: The MES system confirms the material information and serial number fed back by the automated assembly system. If the material number is incorrect, it calls the technician to handle it. If the material number is correct, the product with that serial number is marked as consumed and the relevant information is fed back to the warehousing and logistics system.

[0041] Further, step S52 includes:

[0042] S521: When the automated assembly system installs products on the satellite, it needs to collect and record the task status information of the installation process.

[0043] S522: The automated assembly system feeds information back to the MES system, which then classifies and stores the valid information according to process and quality control requirements, and calls for manual processing of abnormal information.

[0044] Furthermore, in step S521, task status information of the installation process is collected and recorded, including photo information, equipment processing information, work step execution information, material information, and detailed abnormal information.

[0045] Further, step S53 includes:

[0046] S531: The automated assembly system feeds back the process completion information to the MES system;

[0047] S532: The MES system verifies the received process completion information and judges the completeness of process execution;

[0048] S533: Verify whether all processes at this workstation are completed. If there are still processes waiting to be completed, return to step S41 to continue with the next request for a work order signal. If all processes are completed, the MES system recognizes that the last process is completed, reports the process, and returns to step S5 to issue the next production task.

[0049] The information interaction method between the satellite automated assembly system and the MES system provided by this invention, based on the information recording requirements of the traditional satellite assembly process and combined with the distribution requirements of the automated assembly system workstations according to the production cycle of batch satellites, classifies information according to the hierarchical relationship and internal logic of workstations and processes, in order to achieve information interaction between the automated assembly system and the MES system. Before the automated assembly system executes the automated assembly process, the MES system transmits production tasks, programs, and material logistics information to the automated assembly system, laying the foundation for the smooth progress of the final assembly task at that workstation. After the task start conditions are met, the automated assembly is started. The automated assembly system feeds back information such as start-up, material consumption, process execution, and process completion to the MES system, completing all assembly actions and information transmission in the automated assembly process. During each process execution, the MES system judges and handles anomalies based on the received feedback information. When all processes are completed without anomalies, the information exchange between the automated assembly process and the MES system stops, and the MES system issues the next production task to the workstation. This achieves information exchange between the automated assembly system and the MES system, ensuring the orderly and efficient implementation of different production tasks at the workstation and all processes within each production task.

[0052] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0053] The terms "first," "second," "third," "fourth," etc., used in the specification and claims of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0054] Example 1

Please refer to... Figure 1 The information interaction method between the satellite automatic assembly system and the MES system provided in this embodiment of the invention includes an automatic assembly system, which includes an automatic control system. A PLC central control system and a host computer system are configured on the automatic control system. The PLC central control system is integrated with the mechanisms in the automatic assembly system to achieve motion control. The host computer system interfaces with the MES system to achieve information interaction of production task information, material logistics information, automated assembly process information, and assembly quality information.

[0056] It should be noted that the manufacturing of mass-produced satellites generally involves designing multiple automated assembly systems at different workstations based on the production cycle and the satellite product envelope and interfaces. Each automated assembly system performs different assembly actions to achieve continuous automated installation of the satellites. The automated assembly system interacts with the MES system with a large amount of information and high immediacy. Therefore, it is necessary to effectively classify and logically organize the interactive information in conjunction with the process and assembly process to ensure smooth and complete information interaction. In this invention, based on the information recording requirements of the traditional satellite assembly process and combined with the distribution requirements of the automated assembly system workstations according to the production cycle of mass-produced satellites, the information is classified according to the hierarchical relationship and internal logic of the workstations and processes in order to achieve information interaction between the automated assembly system and the MES system.

[0057] S100: Automatic assembly station information interaction method. Specifically, the automatic assembly station and the MES system rely on the host computer system to realize information interaction.

[0058] Specifically, the following steps are included:

[0059] S1: The MES system sends the production plan information (production task order) to the host computer system. After receiving the information, the host computer system scans the satellite product information of its workstation and feeds back the information obtained from the scan to the MES system for verification of the production task information.

[0060] S2: The automatic assembly system operates based on the set program in the automatic control system. Generally, for different types of satellites and production tasks, the automatic control system will generate and save different operating programs. When the production task information is verified to be correct, the MES system will send the corresponding operating program information to the host computer system, and the host computer system will send the program information to the PLC central control system to implement the production action control of the automatic assembly system.

[0061] S3: Materials for the automated assembly system during operation need to be delivered by the warehousing and logistics system. Before the assembly action is executed, the automated assembly system automatically determines whether materials need to be delivered based on the material information in the pallets at the workstation. If so, the demand information is fed back to the MES system, which then automatically calls for material delivery. After delivery, the host computer system controls the automated assembly system to scan the pallet information and call the MES system interface to obtain material information for the final assembly process.

[0062] S4: The automated assembly system receives the production task number and confirms the start-up information with the MES system before starting work by running the automated program;

[0064] S200: Automatic assembly process information interaction method. Specifically, the automatic assembly process and the MES system rely on the PLC central control system and the host computer system to realize information interaction.

[0065] Specifically, the following steps are included:

[0066] S4: The automatic assembly system receives the production task number and confirms the start-up information with the MES system before starting work by running the automatic program. Specifically, the start-up confirmation information is transmitted from the host computer to the MES system. After the MES system confirms that there are no errors, it feeds back the start-up information to the host computer system, which then transmits it to the PLC control system. The PLC control system then starts running the program and starts production according to the set parameters.

[0067] S51: During the production process, the automated assembly system scans and obtains the consumed materials, and feeds the information back to the MES system through the host computer system. The MES system verifies and records the material consumption.

[0068] S52: During the production process, the automated assembly system feeds back program error information and product defect information to the MES system through the host computer system. The MES system then calls on technicians to handle the error.

[0069] S53: After the automatic assembly system completes a certain process, it uploads the completion information and quality control information during the process to the MES system through the host computer system. After verification, the MES system triggers the start signal of the next process and feeds the signal back to the host computer system. The host computer system then transmits the signal to the PLM central control system to prepare for the start of the next process.

[0070] The information interaction method between the satellite automated assembly system and the MES system of this invention, based on the information recording requirements of the traditional satellite assembly process and combined with the distribution requirements of the automated assembly system workstations according to the production cycle of batch satellites, classifies information according to the hierarchical relationship and internal logic of workstations and processes to achieve information interaction between the automated assembly system and the MES system. Before the automated assembly system executes the automated assembly process, the MES system transmits production tasks, programs, and material logistics information to the automated assembly system, laying the foundation for the smooth execution of the final assembly task at that workstation. After the task start conditions are met, the automated assembly program is started, and the automated assembly system feeds back information such as start-up, material consumption, process execution, and process completion to the MES system, completing all assembly actions and information transmission of the automated assembly process. During the execution of each process step, the MES system judges and handles anomalies based on the received feedback information. When all processes are completed and there are no anomalies, the information interaction between the automated assembly process and the MES system stops, and the MES system issues the next production task to the workstation. This achieves information interaction between the automated assembly system and the MES system, ensuring the orderly and efficient implementation of different production tasks at the workstation and all processes within each production task.

[0084] Step S4 of the present invention includes:

[0085] S41: Considering the situation where the assembly process is stopped and restarted or resumed due to abnormalities, material or planning factors during the execution of the assembly task, the automatic assembly system sends a request for work order signal to the MES system at the same time when executing the automatic assembly process.

[0086] S42: After receiving the work order request information, MES performs work order start verification. If there is a problem with the verification, the MES system will send the error information to the automated assembly system, the system will issue an exception warning, and the MES system will call the technicians to handle the exception. If the verification passes, work can start.

During each process execution, the MES system judges and handles anomalies based on the received feedback information. When all processes are completed without anomalies, the information interaction between the automated assembly process and the MES system stops, and the MES system issues the next production task to the workstation. This achieves information interaction between the automated assembly system and the MES system, ensuring the orderly and efficient implementation of different production tasks at the workstation and all processes within each production task.
