[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0033] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0034] In an exemplary embodiment, Figure 1 As shown, a cross-network file interaction method based on physical isolation is provided. The method is executed by a computer device, and can be executed by a computer device such as a terminal or a server alone, or by a terminal and a server together. In the embodiment of the present application, the method is applied to a server as an example for explanation, and includes the following steps.
[0035] The cross-network file interaction method based on physical isolation mentioned in this application is applied to an interactive network; the interactive network includes one or more subnets; wherein the subnets include: an interconnected cloud platform, an enterprise resource management system, and a manufacturing execution system. Figure 1 As shown, the cross-network file interaction method based on physical isolation includes:
[0036] Step 100: Get information instructions. Information instructions are control instructions issued by the cloud platform to retrieve data information. Specifically, information instructions are instructions in 16-bit coded form.
[0037] Step 200: Adjust the network connection according to the information instruction to obtain the adjusted connection status data. The network connection adjustment is based on the difference in the connection network of the single-chip microcomputer corresponding to the enterprise resource management system and the manufacturing execution system, and adjusts the connection status.
[0038] Step 300: Based on the adjusted connection status data, information interaction and data reading and writing are performed according to the information instruction, wherein the interaction cycle of the information interaction is not less than 10 seconds.
[0039] In one embodiment, based on adjusting the connection state data, information interaction and data reading and writing are performed according to the information instruction, specifically including:
[0040] When the single-chip microcomputer corresponding to the enterprise resource management system is connected to the lower computer and is in normal state, the mobile storage device is connected to the enterprise resource management system; when the data interaction of the enterprise resource management system is completed and the information interaction of the manufacturing execution system is required, the single-chip microcomputer corresponding to the enterprise resource management system receives the information instruction to control the corresponding relay to switch to the manufacturing execution system to read and write data; when the information interaction of the manufacturing execution system is completed, the single-chip microcomputer corresponding to the manufacturing execution system controls the single-chip microcomputer corresponding to the manufacturing execution system to reset the relay corresponding to the enterprise resource management system to the initial state.
[0041] When the single-chip microcomputer corresponding to the manufacturing execution system is connected to the lower computer and is in a normal state, the mobile storage device is connected to the manufacturing execution system; when the data interaction of the manufacturing execution system ends and the information interaction of the enterprise resource management system is carried out, the single-chip microcomputer corresponding to the manufacturing execution system receives the information instruction to control the corresponding relay to switch to the enterprise resource management system for data interaction; when the information interaction of the enterprise resource management system is completed, the single-chip microcomputer corresponding to the enterprise resource management system controls the single-chip microcomputer corresponding to the enterprise resource management system to reset the relay corresponding to the manufacturing execution system to the initial state.
[0042] In one embodiment, the types of network connection adjustment instructions include: reset instructions, switch instructions, and default initial state instructions.
[0043] As an optional implementation method, a cross-network file interaction method based on physical isolation supports the interaction of structured data and unstructured data; wherein the unstructured data interacts as an attachment to the structured data, and under the condition that the relevant information of the file server is pre-configured, the attachment location needs to be marked in the structured data.
[0044] In practical applications, this application can complete the interaction of files and data according to the different states of the manufacturing execution system and the enterprise resource management system. Figure 2 As shown, by default, the storage device of the manufacturing execution system is connected to the manufacturing execution system, and the storage device of the enterprise resource management system is connected to the enterprise resource management system. The connection can be switched according to the instructions of the host computer of the manufacturing execution system and the host computer of the enterprise resource management system, that is, when the cloud platform issues information instructions, that is, when files and data need to be interacted, and after the interaction is completed, it is restored to the default connection state. The device mainly realizes:
[0045] 1) Files and data can be transmitted according to the needs of cross-network interactive devices, and the interactive data are isolated from each other.
[0046] 2) After the data exchange between the manufacturing execution system and the enterprise resource management system is completed, the status can be reset. During the whole process, the networks between the enterprise resource management system and the manufacturing execution system are physically isolated from each other.
[0047] The lower computer (single-chip microcomputer) uses an ARM-based lower computer control relay to switch the mobile storage device port.
[0048] The host computer needs to provide two connection states to the slave computer, connecting the manufacturing execution system and the enterprise resource management system respectively. The host computer sends the information to the slave computer in the form of 16-bit code, and the slave computer makes adjustments based on the received information. According to the different connection networks of the microcontroller, it is divided into the enterprise resource management system connecting the slave computer and the manufacturing execution system connecting the slave computer. There are three types of instructions: reset instruction, switch instruction, and default initial state instruction.
[0049] When the ERP system is connected to the lower computer, the removable storage device is connected to the ERP system in a normal state. When the ERP system data interaction is completed and the MES information interaction is required, the ERP system microcontroller receives the host computer instruction, and the storage device is connected to the MES for data reading and writing. When the MES information interaction is completed, the MES computer controls the MES microcontroller to reset the ERP system relay to the initial state, that is, switch back to the connection with the ERP system.
[0050] On the contrary, when the manufacturing execution system is connected to the lower computer in a normal state, the removable device is connected to the manufacturing execution system. When the data interaction of the manufacturing execution system ends and the information interaction of the enterprise resource management system is carried out, the manufacturing execution system microcontroller receives the instructions of the manufacturing execution system computer, and the removable storage device switches to the enterprise resource management system for data interaction. When the information interaction of the enterprise resource management system is completed, the enterprise resource management system computer controls the enterprise resource management system microcontroller to reset the manufacturing execution system relay to the initial state, that is, switch back to the connection with the manufacturing execution system.
[0051] In order to be able to be ported to different platforms in the future, the upper computer software application is developed in Java. The database uses MySQL to ensure the stability of the queue and reduce the procurement cost. The application is a BS system architecture. The client delivers data to one side of the interactive system through RESTFul requests, and the system will periodically interact with the data to another network environment. The main technology stack used by the system is shown in Table 1.
[0052] Table 1 System main technology stack
[0053] Function Product Name Application Platform JDK1.8 database MySQL8 Database persistence (ORM) MyBatis-Plus MVC Framework SpringMVC IOC Container SpringBoot
[0054] The enterprise resource management system data is backed up periodically to the manufacturing execution system, which facilitates the information exchange between the enterprise resource management system and the manufacturing execution system. The shortest interaction cycle can be about 10 seconds.
[0055] Hardware circuit design: The hardware circuit mainly includes the schematic diagram and PCB circuit diagram design. The serial port interaction chip uses the CH340 chip for data interaction. By controlling the microcontroller pin level, driving the optocoupler, driving the relay action, the switching of the storage device connection is completed;
[0056] Structural design: The structural design uses 3D printed PLA filament as the overall appearance, such as Figure 3 As shown, openings for connecting to the host computer are designed on both sides of the shell to complete the connection of the USB data cable.
[0057] Embedded programming: the overall process is as follows Figure 4 As shown in the figure, add serial port interrupt to the main program to monitor and read serial port information. Introduce external interrupt to complete the operation of resetting the relay of the microcontroller. After the data interaction is completed, restore the relay to the initial state. Add a watchdog timer, and the main program loop will set the watchdog. If it is not set within 200ms, perform a hardware reset operation on the microcontroller to avoid abnormal operation of the microcontroller program.
[0058] like Figure 5 As shown, the host computer system mainly completes functions such as data delivery, security authentication mechanism, attachment processing, interactive services, and data interaction. The specific description is as follows.
[0059] Data delivery:
[0060] The system supports multi-line data delivery. Different types of business data are distinguished by built-in identifiers in the system. Data interaction of different data structures can be achieved after simple configuration, greatly reducing the cost of application maintenance.
[0061] Security authentication mechanism:
[0062] The data provider provides the interactive administrator with system information, and the data interactive system generates the access AppId and AppSecret as the authentication basis for subsequent service calls. Before calling the data collection interface each time, you need to call this interface to generate an access token (Token) and write the Token to the header information of the interface to be called. The interactive system will authenticate all data services.
[0063] Attachment handling:
[0064] The system supports the interaction of structured data and unstructured data, where unstructured data is interacted as an attachment to structured data. Under the condition that the relevant information of the file server is configured in advance, the client does not need to submit unstructured data. It only needs to indicate the attachment location in the structured data. The interactive system will automatically download the file and transfer it to the other side of the interactive system, which can greatly reduce the development workload when the client connects to the interactive system.
[0065] Interactive Services:
[0066] The system has an independent scheduled task, which scans the data in the queue with the status of "waiting" at intervals (configurable before the application is started), organizes all such data into batches, and generates text files according to different business groups. Then it is copied to the specified location of the interactive machine (configurable), and after all data serialization is completed, the interactive machine is notified to mount and transfer to the network environment on the other side.
[0067] Data interaction:
[0068] The interactive system application is designed to decouple the data delivery service and the interactive service, and the two communicate through the data queue. That is, after receiving the data, the data delivery service organizes the data into batches and gives the data in this batch an "initialized" status value. At this time, even if the system triggers the scheduled scanning task, it will not process the data. Only when all the data this time enters the queue, the system will uniformly change the data status of this batch to "waiting". This relies on the row lock mechanism of the database.
[0069] In an exemplary embodiment, a cross-network file interaction device based on physical isolation is provided, comprising:
[0070] The acquisition module is used to obtain information instructions; information instructions are control instructions issued by the cloud platform to retrieve data information.
[0071] The connection status adjustment module is used to adjust the network connection according to the information instruction to obtain the adjusted connection status data; the network connection adjustment is based on the difference in the connection network of the microcontroller corresponding to the enterprise resource management system and the manufacturing execution system, and adjusts the connection status.
[0072] The interaction module is used to perform information interaction and data reading and writing according to information instructions based on adjusting the connection status data.
