Description

Technical Field

[0001] This application relates to the field of industrial automation and intelligent manufacturing technology, and in particular to a collaborative operation system and method for dual gasoline filling equipment in an automobile assembly workshop. Background Technology

[0002] The gasoline filling station in the automobile assembly workshop is one of the key processes in vehicle production. Traditional filling operations mostly rely on manual operation or independent operation of a single machine, which has problems such as low automation, low work efficiency, and high labor intensity. In addition, it is difficult to achieve real-time collection, centralized management and traceability analysis of filling operation data.

[0003] To improve production line management, Manufacturing Execution Systems (MES) have been widely adopted in automotive assembly workshops. As a crucial bridge connecting the enterprise's upper-level planning and management system (ERP) with the lower-level industrial control system (such as PLC), the enterprise MES system can realize functions such as production planning and scheduling, resource allocation, process control, and data traceability. However, the integration of existing refueling equipment with the enterprise MES system is low, failing to fully leverage the management advantages of the enterprise MES system. Furthermore, the lack of an effective collaborative operation mechanism between multiple refueling devices easily leads to problems such as operation conflicts and duplicate operations, resulting in low efficiency and a low level of intelligence in gasoline refueling operations at the automotive assembly workshop.

[0004] Therefore, there is an urgent need for an automated refueling system and method that can enable multiple refueling devices to work together and be deeply integrated with the enterprise's MES system, in order to improve the operational efficiency and intelligence level of the gasoline refueling station in the automobile assembly workshop. Summary of the Invention

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] The purpose of this application is to provide a collaborative operation system and method for dual gasoline refueling equipment in an automobile assembly workshop. It is applicable to the automation and intelligent operation transformation of gasoline refueling stations in automobile assembly workshops. The aim is to realize the automated collaborative operation of multiple refueling equipment, improve refueling efficiency, reduce labor intensity, and realize real-time synchronization of refueling data with the enterprise's MES system to complete centralized management and traceability analysis of refueling data.

[0043] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] This application proposes a collaborative operation system for dual gasoline refueling equipment in an automobile assembly workshop, which includes a hardware execution unit and a software control unit.

[0045] The hardware execution unit includes at least two refueling devices 1 and at least two industrial control terminals 2. Each industrial control terminal 2 is communicatively connected to a corresponding refueling device 1 and is used to control the refueling device 1 to refuel gasoline.

[0046] The software control unit is deployed in each of the industrial control terminals 2 and is used to realize automatic control, data interaction and collaborative scheduling of the filling operation.

[0047] Each of the industrial control terminals 2 is also connected to the enterprise MES system to obtain gasoline refueling operation information from the enterprise MES system and upload vehicle refueling operation result data to the enterprise MES system.

[0048] A point-to-point communication connection is established between each of the industrial control terminals 2. The communication connection between the industrial control terminals 2 is used to realize the allocation of work tasks. Each industrial control terminal 2 is used to monitor its corresponding refueling device 1 to complete the automated refueling operation.

[0049] As an optional implementation, since the enterprise's final assembly line only reserves one network port at the gasoline refueling station, this embodiment adopts a master-slave communication architecture. Specifically, each pair of industrial control terminals 2 adopts a master-slave communication architecture, and interacts with the enterprise's MES system through a shared network communication interface. Each industrial control terminal 2 shares the gasoline refueling operation information in the enterprise's MES system. The gasoline refueling operation information includes refueling parameters such as vehicle VIN code, target refueling volume, vehicle model, and fuel type.

[0050] As an optional implementation, the dual gasoline refueling equipment collaborative operation system in the automobile assembly workshop adopts a dual-machine collaborative operation mechanism. This mechanism utilizes a master-slave structure of "at least two industrial control terminals 2 + at least two refueling devices 1" to achieve dynamic allocation and collaborative execution of refueling tasks. In this master-slave structure, each of the two refueling devices 1 is controlled by an independent industrial control terminal 2, with one terminal acting as the master and the other as the slave. The master and slave terminals establish a data interaction channel via UDP communication to achieve real-time sharing of refueling task information and operation status. During system operation, refueling tasks are not pre-assigned to a specific device, but are dynamically scheduled based on the actual operating status. When any of the refueling devices 1 performs a refueling operation, the system automatically obtains the next gasoline refueling operation information. At this time, the system automatically assigns the next gasoline refueling operation information, and idle refueling devices can use this gasoline refueling operation information to perform the refueling operation. At this time, the two refueling devices 1 operate simultaneously, forming a continuous task flow mechanism. In this way, the two refueling devices 1 can operate in parallel within the same time period, rather than being assigned refueling operations according to fixed rules, thereby realizing the parallel and collaborative operation of two gasoline refueling devices.

[0057] As an optional implementation, the industrial control terminal 2 includes a power supply module 21, a main control module 22, a display module 23, an alarm indication module 24, an identification module 25, and a heat dissipation module 26.

[0058] The main control module 22 is communicatively connected to the display module 23, the alarm indication module 24, and the identification module 25, respectively. The main control module 22 is used to control the display module 23, the alarm indication module 24, and the identification module 25 to respectively realize the display of vehicle refueling operation results, alarm indication, and barcode identification functions.

[0059] The power supply module 21 is connected to the main control module 22 and the heat dissipation module 26 respectively. The power supply module 21 is used to supply power to the main control module 22 and the heat dissipation module 26 respectively. The heat dissipation module 26 is used to dissipate heat from the industrial control terminal 2 as a whole.

[0060] As an optional implementation, the software control unit includes a user management module and a refueling operation module.

[0061] The user management module is used to manage the account information, permission allocation, and identity authentication of operators.

[0062] The refueling operation module includes an MES interaction submodule, an equipment monitoring submodule, and a status management submodule.

[0063] The MES interaction submodule is used to realize the data interaction between the industrial control terminal 2 and the enterprise MES system.

[0064] The equipment monitoring submodule is used to monitor the operation status, control gasoline refueling, and handle abnormalities of the refueling equipment 1 corresponding to the industrial control terminal 2.

[0065] The status management submodule is used to configure parameters, display operating status, and perform refueling data statistics and display for the software control unit. The refueling data includes gasoline refueling operation information and vehicle refueling operation result data.

[0066] As an optional implementation, the MES interaction submodule adopts a three-level interaction architecture of "industrial control software - data access middleware - database server" to establish a communication connection between the industrial control terminal 2 corresponding to the software control unit and the enterprise MES system, so as to realize the local storage and uploading of vehicle refueling operation result data and the synchronization of gasoline refueling operation information.

[0067] As an optional implementation, the equipment monitoring submodule can send corresponding control commands according to the communication protocol of the dispensing device 1 to realize the switching of the working mode, quantitative dispensing control and dispensing status start and stop control of the dispensing device 1.

[0068] As an optional implementation, the status management submodule is configured with a human-machine interface. The human-machine interface is equipped with various function sub-menu buttons. The human-machine interface is used to display the running status of the software control unit in real time and supports the retrieval, viewing and statistical analysis of historical data.

[0069] In an exemplary embodiment, to illustrate the technical solutions provided in the embodiments of this application in detail, the following are provided: Figure 1 The system shown is a collaborative operation system for dual gasoline refueling equipment in an automobile assembly workshop. The system mainly includes a hardware execution unit and a software control unit.

[0070] Taking a dual-filling equipment as an example (i.e., equipped with two filling devices 1 and two industrial control terminals 2), the hardware execution unit includes two filling devices 1 and two industrial control terminals 2. The vehicle to be filled on the accompanying platform arrives at the gasoline filling station along the production line's movement direction. The accompanying platform refers to the platform used to carry the vehicle to be filled and move it along the production line's movement direction. The two filling devices 1 are designated as the left and right filling devices according to the production line's movement direction. The software control unit includes a user management module and a filling operation module, corresponding to the user login program and the filling program, respectively. The user login program and the filling program are written in LabVIEW, enabling software-level user login management and automated filling operations.

[0071] As an optional implementation, the industrial control terminal 2 communicates with the enterprise MES system via a TCP / IP network port, and the industrial control terminal 2 communicates with the dispensing device 1 via a serial port. Through serial communication, the industrial control terminal 2 monitors the dispensing device 1 to complete the automatic dispensing operation.

[0072] As an optional implementation, each of the two industrial control terminals 2 controls one refueling device 1. The industrial control terminals 2 establish communication via UDP. The two industrial control terminals 2 adopt a master-slave communication architecture (i.e., the two industrial control terminals 2 include one master industrial control terminal and one slave industrial control terminal, and both use the same network port to communicate with the enterprise MES system). Figure 2 The collaborative operation process of two refueling devices is illustrated. The master industrial control terminal obtains gasoline refueling operation information from the enterprise's MES system and assigns it to the slave industrial control terminal. The master and slave industrial control terminals share the gasoline refueling operation information from the enterprise's MES system via UDP communication. Refueling tasks are dynamically allocated based on the device's idle status through competition. The winning party executes the refueling task and uploads the refueling result, while the losing party waits for the next allocation. This achieves parallel operation and continuous task flow for the two refueling devices. UDP is used to establish a communication relationship between the two industrial control terminals 2, enabling them to share the same network port, utilize the gasoline refueling operation information and vehicle refueling operation result data from the enterprise's MES system, and transmit the vehicle refueling operation result data back to the enterprise's MES system.

[0073] As an optional implementation, the refueling device 1 includes a refueling execution component, an information reading component, and an input operation component. The refueling device 1 is a fuel dispenser, the refueling execution component is a fuel nozzle, the information reading component is an IC reader, and the input operation component is a matrix keypad. It can be matched with different types of gasoline (e.g., 92-octane gasoline and 95-octane gasoline) and perform quantitative refueling respectively.

[0074] Each refueling device 1 is equipped with multiple fuel nozzles, multiple IC readers, and multiple matrix keypads, corresponding to quantitative refueling operations for various types of gasoline, achieving matching and quantitative refueling of different types of gasoline. The specific number of each component can be set according to the type of gasoline to be refueled. For example, taking 92-octane and 95-octane gasoline as an example, two independent fuel nozzles are set on refueling device 1 to refuel 95-octane and 92-octane gasoline respectively, without interference between them. The fuel nozzles, IC readers, and matrix keypads are devices on refueling device 1 and are integrated into the refueling device 1.

[0075] As an optional implementation method, such as Figure 3 As shown, the industrial control terminal 2 includes a power supply module 21, a main control module 22, a display module 23, an alarm indication module 24, an identification module 25, and a heat dissipation module 26. The main control module 22 communicates with the display module 23, the alarm indication module 24, and the identification module 25 via a hub through serial ports. Serial communication enables information exchange and function execution between the modules within the industrial control terminal 2. The identification module 25 preferably uses a barcode scanner to scan the vehicle's VIN code and obtain vehicle identification information.

[0076] Figure 4 The system's overall hardware networking and communication connections are illustrated. The core is based on an industrial LAN, with the enterprise MES system's MES server and SQL server serving as the data core. This network connects clients and other workstations on the production line. The main and slave industrial control terminals communicate via UDP, and both are connected to their respective hubs via RS232 communication. Each hub establishes communication with its corresponding left and right dispensing devices via RS-422, thus enabling communication between the industrial control terminals and the dispensing devices. The barcode scanner and audible / visual alarm lights establish communication connections with their respective main and slave industrial control terminals via serial ports. This forms a multi-device, multi-communication protocol integrated hardware network architecture, ensuring data transmission and command interaction among the hardware units.

[0077] like Figure 5 As shown, the software program in the software control unit includes a master industrial control terminal program and a slave industrial control terminal program. Both the master and slave industrial control terminal programs include programs related to personnel management, parameter configuration, and result statistics. The system performs self-checks and automatically runs the corresponding refueling program after user login, realizing automated refueling, data interaction, and status control at the software level.

[0078] As an optional implementation, the refueling operation module includes an MES interaction submodule, an equipment monitoring submodule, and a status management submodule.

[0079] As an optional implementation, the MES interaction submodule is used to read gasoline refueling operation information from the enterprise MES system and save it locally, and to read vehicle refueling operation result data locally and upload it to the enterprise MES system; the equipment monitoring submodule is used to control the operating status of refueling equipment 1 according to the refueling parameters configured according to the enterprise MES system and display the actual refueling amount in real time, and save the refueling result after the refueling operation is completed to obtain vehicle refueling operation result data; the status management submodule is used to implement functions such as software configuration, data viewing and statistics.

[0080] In this embodiment, the communication and interaction between the industrial control terminal 2 and the enterprise MES system is realized through the MES interaction submodule, the automated control of the filling equipment 1 is realized through the equipment monitoring submodule, and the status management submodule enables users to enter the corresponding function interface by clicking the menu on the main interface, such as data viewing and statistics, software configuration, system exit, etc.

[0081] As an optional implementation, the MES interaction submodule adopts a three-tier interaction architecture of "industrial control software - data access middleware - database server," wherein the industrial control software is preferably LabVIEW, the data access middleware is preferably Microsoft Data Access Middleware, and the database server is preferably SQL Server. Through the steps of "LabVIEW → Microsoft Data Access Middleware → SQL Server," the interaction relationship between the industrial control terminal 2 and the enterprise MES system is established, enabling the acquisition of gasoline refueling operation information and the uploading of local data to the enterprise MES system. Specifically, a data link can be created using the LabVIEW Database Connection Toolkit to achieve communication between the industrial control terminal 2 and the enterprise MES system, acquire gasoline refueling operation information, and upload vehicle refueling operation result data, ensuring the stability and accuracy of data interaction.

[0082] As an optional implementation, the equipment monitoring submodule can send control commands and switch working modes according to the communication protocol of the refueling device 1; the equipment monitoring submodule can realize automatic quantitative control through instruction codes; the equipment monitoring submodule has functions such as starting and stopping the motor of the refueling device and controlling the opening and closing of the control valve; the equipment monitoring submodule can query the status of the main board and obtain real-time refueling data; the equipment monitoring submodule has the function of storing refueling data into the storage device.

[0083] This application embodiment realizes real-time monitoring and functional control of the filling equipment 1 through the equipment monitoring submodule, so as to achieve the effect of automatically executing the filling operation and realize full-process monitoring of the filling equipment 1.

[0084] As an optional implementation, the status management submodule can execute corresponding function modules by clicking the system menu; the status management submodule has the function of clicking buttons in the program interface to execute preset completed button functions; the information prompt box in the status management submodule interface can directly display the current running status of the software to the operator; the status management submodule has functions such as data information retrieval, data viewing, and gasoline refueling operation information statistics, and can perform multi-dimensional retrieval of historical refueling data on the local data of the industrial control terminal 2 (e.g., according to vehicle VIN code, refueling time, actual refueling amount, equipment number, etc.).

[0085] This application embodiment realizes human-computer interaction through the status management sub-module. Operators can click on the corresponding function module to complete operations such as retrieving and querying historical refueling data and changing system configurations as needed, providing operators with a convenient operation method and comprehensive data analysis support.

[0086] Figure 6The hierarchical architecture and functional division of the software control unit are shown. The software control unit is divided into a user management module and a refueling operation module (including an MES interaction submodule, an equipment monitoring submodule, and a status management submodule). Among them, the user management module undertakes basic management functions such as user login authentication, permission allocation management, and account lifecycle management. The MES interaction submodule, equipment monitoring submodule, and status management submodule respectively implement MES system data interaction (communication status judgment, reading refueling code, uploading vehicle refueling operation result data), full-process control and real-time data acquisition of refueling equipment 1 (refueling equipment status monitoring, real-time refueling volume display, saving vehicle refueling operation result data), system parameter configuration and human-machine interaction operation (data filtering and viewing, data uploading, data statistics), etc. The modules are clearly hierarchical and have well-defined division of labor, which together constitute a complete software control system.

[0087] The collaborative operation system for dual gasoline refueling equipment in the automobile assembly workshop proposed in this application includes the following steps in its specific working process.

[0088] Step 1: When a vehicle enters the refueling station in the automobile assembly workshop, the industrial control terminal 2 obtains gasoline refueling operation information from the enterprise's MES system, including vehicle identification information and preset refueling parameters. This allows the system to determine the vehicle model information and then refuel the vehicle with the corresponding type of gasoline based on the vehicle identification information and preset refueling parameters. If the information cannot be obtained automatically, the vehicle identification information can be obtained by manually scanning the vehicle's VIN code through the identification module 25, and the refueling parameters can be manually configured.

[0089] Step 2: Each industrial control terminal 2 interacts with the operation status through point-to-point communication. The refueling task is automatically assigned to the corresponding industrial control terminal 2 according to the collaborative allocation strategy. The collaborative allocation strategy is based on the equipment operation status, vehicle refueling needs and production line turnover efficiency.

[0090] Step 3: The industrial control terminal 2 controls the corresponding refueling device 1 to perform the refueling operation through serial communication based on the acquired refueling parameters, and collects and displays the refueling operation data in real time; during the operation, it sends operation status information in real time, and if an abnormality is detected, it issues an alarm signal and suspends the refueling operation.

[0091] Step 4: After the refueling operation is completed, the industrial control terminal 2 will store the refueling results, i.e., the vehicle refueling operation result data (including the actual refueling amount, refueling time, and equipment status), locally, and upload the vehicle refueling operation result data to the enterprise MES system to achieve the synchronization of refueling data.

[0092] Step 5: Operators can configure refueling parameters, retrieve and statistically analyze work data, and view system status through the human-machine interface of the industrial control terminal 2.

[0093] Figure 7 The system software usage process is shown. After starting the software, the operator logs in and can then choose to configure system parameters, manage personnel, upload statistics, log in to the system, or exit the software. The process combines the flexibility of automated execution with manual operation.

[0094] This application proposes a collaborative operation system for dual gasoline refueling equipment in an automobile assembly workshop. By communicating with the enterprise's MES system, it obtains vehicle VIN codes, gasoline refueling operation information, and other data. Two industrial control terminals 2 share the gasoline refueling operation information and vehicle refueling result data, enabling automatic task allocation between the two terminals and control of the two refueling devices 1 to operate collaboratively. Each terminal 2 monitors the refueling device 1 based on the gasoline refueling operation information, achieving automated operation with high automation, low labor intensity, and high efficiency. By connecting the industrial control terminals 2 to the enterprise's MES system, networking the refueling equipment with the system and automatically saving refueling results are achieved, providing detailed gasoline refueling record traceability for the assembly line. This system can be applied to 24-hour continuous gasoline refueling operations on the production line.

[0095] Based on the same inventive concept, this application also provides a method for collaborative operation of dual gasoline refueling equipment in an automobile assembly workshop, based on the aforementioned collaborative operation system for dual gasoline refueling equipment in an automobile assembly workshop. The solution provided by this method is similar to the solution described in the aforementioned system. Therefore, the specific limitations in the embodiments of the collaborative operation method for dual gasoline refueling equipment in an automobile assembly workshop provided below can be found in the limitations of the collaborative operation system for dual gasoline refueling equipment in an automobile assembly workshop described above, and will not be repeated here.

[0099] S3: Save the vehicle refueling operation result data to the local industrial control terminal 2 and upload it to the enterprise MES system.

[0100] This application proposes a collaborative operation system and method for dual gasoline refueling equipment in an automobile assembly workshop. The system includes at least two refueling devices 1 and at least two corresponding industrial control terminals 2. A software control unit runs on each of the industrial control terminals 2, used for automatic control and data management of the refueling operation. Each industrial control terminal 2 independently controls its corresponding refueling device 1 via serial communication. The two industrial control terminals 2 establish a collaborative mechanism via UDP communication, employing a master-slave communication architecture, sharing the same network port to communicate with the enterprise's MES system, achieving unified acquisition and sharing of vehicle VIN codes and refueling parameter information. During operation, the system obtains the vehicle VIN code, model information, and preset refueling parameters from the enterprise's MES system, and automatically allocates the refueling task to the two industrial control terminals 2 according to a collaborative allocation strategy. The corresponding refueling device 1 completes the synchronous or parallel refueling operation. The two industrial control terminals 2 exchange operation status information in real time to avoid refueling conflicts and duplicate operations. After refueling is completed, the system automatically saves the refueling results and uploads them to the enterprise's MES system, achieving centralized management and traceability of refueling data. This application embodiment improves the refueling efficiency and automation level of the production line and reduces labor intensity through the collaborative operation of two gasoline refueling devices 1, and is suitable for the automation transformation of gasoline refueling stations in automobile assembly workshops.

[0101] The collaborative operation system and method for dual gasoline refueling equipment in an automobile assembly workshop proposed in this application have the following advantages.

[0102] (1) By setting up at least two filling devices 1 and corresponding industrial control terminals 2, point-to-point communication is established between each industrial control terminal 2 to achieve collaborative scheduling. A master-slave communication architecture is adopted to connect with the enterprise MES system, realizing the automatic allocation of filling tasks and the parallel operation of dual devices, effectively improving the operation efficiency of the filling station, reducing the intensity of manual labor, and meeting the needs of 24-hour continuous operation of the production line.

[0103] (2) The system is deeply integrated with the enterprise MES system, realizing the unified acquisition of vehicle identification information and the real-time uploading of vehicle refueling operation results data. It has completed the centralized management and traceability analysis of refueling data, providing accurate data support for production line scheduling and cost control.

[0104] (3) The refueling equipment 1 is adapted to the quantitative refueling requirements of different types of fuel. The industrial control terminal 2 integrates multiple modules such as display, alarm, and identification. The software control unit is equipped with complete human-computer interaction and data processing functions, which improves the system's adaptability, operational flexibility and data analysis capabilities.

[0105] (4) When multiple refueling devices 1 work together, an allocation strategy is formulated based on the real-time operating status of the devices (idle status, working status or fault status), which effectively avoids refueling operation conflicts and duplicate operations. At the same time, an abnormal alarm mechanism is set up to ensure the stability and accuracy of the refueling operation and improve the intelligent operation level of the production line.
