[0002] In the field of computer ERP systems, to ensure the security of core business data, enterprises typically deploy ERP systems in a physically isolated intranet environment, strictly prohibiting internet access and the deployment of wireless network facilities. While this architecture effectively prevents the risk of data leakage caused by external attacks, it severely restricts the use of mobile devices such as PDAs in business scenarios.

[0003] Currently, although there are some methods for applying wireless network technology to enterprise intranets, most of these methods pose data security risks and cannot effectively solve the problem of intranet data leakage in wireless environments.

[0020] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] The embodiments of the present application provide a PDA data interaction method, device and medium based on a wireless private network to solve the following technical problem: how to build a wireless private network environment while ensuring the security of intranet data so as to enable interaction between PDA mobile applications and intranet ERP data.

[0022] The technical solutions proposed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0023] Figure 1 The present invention provides a flow chart of a PDA data interaction method based on a wireless private network. Figure 1 As shown, the embodiment of the present application provides a PDA data interaction method based on a wireless private network, which specifically includes the following steps:

[0024] Step 10: Obtain the business documents to be operated in the intranet and pre-process them to obtain the target business documents.

[0025] As an optional embodiment, pre-processing the business documents to be operated to obtain target business documents may specifically include: Step 101: Based on preset business requirements, screening the business documents to be operated to obtain required business documents.

[0026] In this step, different business scenarios and management goals within the enterprise will correspond to different data operation requirements. Based on the enterprise's actual business processes, management rules and specific business goals, a series of data operation requirements are pre-defined, including business scenario limitations, for example, clarifying which business scenarios need to be operated through PDA mobile applications, such as material receipt in the procurement system and material inventory in the inventory system; data scope limitations, determining which types of business documents or data need to be operated; operation authority limitations, according to the enterprise's management rules, setting specific users or roles to operate specific business documents to ensure compliance of operations.

[0027] Step 102: Perform a data integrity check on the demand business document. If there are missing fields in the demand business document, supplement the missing field information using the preset association rules, and map the sensitive data fields in the demand business document based on the preset mapping rules to generate the target business document.

[0028] In this step, data integrity check refers to the verification of various fields of the demand business document during the data processing process to check whether the demand business document contains all required fields. For example, some business documents may need to include fields such as material number, material name, quantity, etc. Through integrity check, business logic errors or operation failures caused by incomplete data can be avoided; association rules are pre-defined data association logic used to obtain information about missing fields from other data sources. If missing fields are found in the demand business document during the data integrity check, the missing information is supplemented by the association rules; furthermore, the intranet ERP system inevitably involves some supplier information, material costs, etc. Such sensitive data fields need to be mapped, and the original sensitive data is converted into non-sensitive alternative values ​​according to the pre-defined data conversion logic; after data integrity check, missing field supplementation and sensitive data field mapping, the generated target business document contains all necessary information while avoiding the risk of sensitive data leakage.

[0029] Step 103: Lock the target business document and generate a unique access identifier to prohibit the target business document from being edited in the intranet.

[0030] In this step, because data may be accessed and operated by multiple users simultaneously in the enterprise intranet, which may lead to data conflicts, the target business document obtained after preprocessing is locked before transmission. This ensures that the status of the target business document in the intranet is fixed and will not be changed due to operations in the intranet. After locking the document, a unique identifier is created for the locked target business document, which is used to uniquely identify and access the document in subsequent operations.

[0031] Step 20: Based on the data ferry technology, the target business document is transmitted to the preset wireless private network, and the target business document is structured to obtain structured data.

[0032] As an optional embodiment, the method further includes: Step 201: Building a wireless private network.

[0033] As an optional embodiment, building a wireless private network may specifically include: Step 2011: configuring independent network equipment in a physically isolated network environment from the intranet to build an independent wireless private network architecture.

[0034] In this step, the physically isolated network environment refers to a network space that is completely separated from the enterprise intranet, which is achieved through physical means to ensure that there is no direct physical connection between the two networks. Physical isolation can effectively prevent intranet data from being leaked to the external network through network vulnerabilities or unauthorized access. Through physical isolation, intranet data is protected in a relatively closed and secure environment; in the physically isolated network environment, network equipment specifically used to build a wireless private network is installed and set up, including but not limited to routers, switches, wireless access points (WAPs), firewalls, etc. By configuring wireless access points, wireless network coverage is provided, so that PDA mobile devices can connect to the wireless private network within the designated area. By configuring firewalls and other security devices, network access control and security protection are provided. The wireless private network architecture operates independently of the intranet and has its own network topology and configuration, so that the wireless private network can focus on supporting PDA mobile applications without being affected by the intranet.

[0035] Step 2012: Deploy the backend application server and call the API interface required by the PDA mobile application to build a wireless private network.

[0036] In this step, the back-end application server is the core component of the wireless private network. It provides necessary service support for PDA mobile applications, including data storage, business logic processing, user authentication, etc. The back-end application server is deployed in a wireless private network environment that is physically isolated from the intranet to ensure its independent operation; at the same time, it calls the API interface required by the PDA mobile application. The API interface is a bridge for data interaction between the PDA mobile application and the back-end application server. It contains security mechanisms such as authentication, authorization and data encryption to ensure the security and integrity of data during transmission, and encapsulates the business logic of the back-end application server, so that the PDA mobile application can implement corresponding business functions through simple calls.

[0037] Step 202: Establish a data ferry channel between the wireless private network and the intranet.

[0038] In this step, the data ferry channel refers to a data transmission mechanism established between two network environments (wireless private network and intranet), which allows data to be securely transmitted between the two networks without the need for direct network connection, while ensuring physical and logical isolation between the two networks. The data ferry channel usually has strict access control and management mechanisms to ensure that only authorized data and operations can be transmitted through the channel.

[0039] Step 203: Set a scheduled task component and import the target business document into the backend application server at a preset time interval.

[0040] In this step, since the design of the data ferry channel needs to follow the principles of non-real-time and non-direct connection, a scheduled task component needs to be set up to automatically execute specific tasks within a preset time interval; the scheduled task component can set different time intervals according to the actual business needs of the enterprise, and can be adjusted according to factors such as the urgency of the business and the frequency of data updates to meet the needs of different business scenarios; the scheduled task component is responsible for scheduling and managing the execution of tasks to ensure that the tasks are triggered at a predetermined time point or time interval; through the scheduled task component, the target business documents are automatically synchronized from the intranet to the wireless private network back-end application server, reducing manual intervention, improving the efficiency and accuracy of data processing, and ensuring that the target business documents are kept up to date on the back-end application server in the wireless private network through preset time intervals, supporting real-time operation of PDA mobile applications.

[0041] Step 204: Structuring the imported target business document to convert the target business document into structured data.

[0042] In this step, since the business form of the original business documents in the intranet environment is relatively complex, in order to avoid intranet data leakage, the original business documents need to be converted into a standardized data model that can be directly and efficiently operated by PDA mobile applications in the wireless private network environment. This process is a key transformation link for data to flow from the intranet to the private network, and aims to solve the data compatibility problem caused by the differences between the two network environments; among them, the structured data includes a status mark field and a numeric field. The status mark field is used to record whether the data has been processed and whether further processing is required. The numeric field is used to record specific business data, such as order quantity, inventory quantity, etc. Through lightweight updates, the PDA avoids processing the entire data record or a large amount of irrelevant data, reducing the load while also avoiding intranet data leakage to a certain extent.

[0043] Step 205: Store the structured data in the wireless private network database.

[0044] Step 30: Use the PDA mobile application to update the structured data to obtain an updated business document.

[0045] As an optional embodiment, the structured data is updated using a PDA mobile application to obtain an updated business document, which may specifically include: Step 301: Synchronizing the structured data with the PDA mobile application through an API interface.

[0046] In this step, the back-end application server exposes a dedicated API interface for the PDA to actively pull data or receive server push. Through the API interface, the PDA mobile application can obtain the latest structured data from the back-end application server regularly or on demand to ensure that the data on the mobile device is the latest. The transport layer adopts a secure encryption mechanism to ensure the confidentiality of data transmission in a wireless environment, and provide a safe and efficient data access portal for mobile terminals in an isolated network environment.

[0047] Step 302: Utilize the PDA mobile application to update the status mark field and / or the numerical field.

[0048] In this step, the PDA mobile application focuses on the update and maintenance of core fields for business document operations, mainly realizing business flow through the precise update of status mark fields and numerical fields; the status mark field is the core identifier of the business document lifecycle management, and its update operation directly reflects the stage of business progress, while the update of numerical fields records the quantitative results generated by business operations. Following the principle of lightweight update, only key fields directly related to business operations are modified to avoid unnecessary data transmission and processing, which not only improves the efficiency of mobile terminal operations but also reduces the complexity of data synchronization.

[0049] Step 303: The updated business document data is transmitted back to the backend application server through the API interface.

[0050] In this step, after the business document is processed on the PDA mobile app, the updated data is transmitted back to the backend application server via a dedicated API. This transmission adopts an incremental update strategy, transmitting only the changed fields, significantly reducing network transmission load. After receiving the updated data, the backend server first performs integrity verification and security validation to ensure that the data complies with predefined business rules and security policies. This mechanism enables the secure and efficient flow of data between the private network environment and the intranet environment, laying a solid foundation for subsequent intranet data processing.

[0051] Step 40: The updated business document is transmitted back to the intranet and marked.

[0052] As an optional embodiment, the updated business document is transmitted back to the intranet and marked, which may specifically include: Step 401: using the data ferry channel to transmit the updated business document in the backend application server back to the intranet, and monitor and audit the transmission process in real time.

[0053] In this step, a multi-dimensional real-time monitoring and auditing system is built during the data ferrying process. By deploying monitoring agents at key nodes of the ferrying channel, key indicators such as data transmission status, data integrity, and transmission timeliness are continuously tracked. The audit module records in detail the operator identity, operation time, transmission data characteristics and other metadata of each transmission to form a complete audit trail; the business documents in the back-end application server that have been lightweight updated by the PDA are packaged as a whole and transferred to the intranet according to the established protocol without any continuous connection with the intranet, thereby maintaining the closed nature of the intranet. At the same time, the real-time monitoring and auditing system is used to centrally store and manage the contents of these business documents.

[0054] Step 402: Record the update timestamp and update source information of the intranet to obtain an updated status identifier.

[0055] In this step, when the intranet receives the updated business document, it automatically records the precise update timestamp and update source information. The update timestamp is generated by a high-precision time service to ensure the consistency and comparability of time stamps in a distributed environment. The update source information includes key elements such as terminal device identification, operator identity, and network access point, forming a complete operation traceability chain. This information is closely related to business data and provides a reliable basis for subsequent data consistency checks and business audits. When the data is transmitted back from the private network to the intranet, the status identification will be automatically updated according to the preset business rules to mark the processing stage of the data. The state management adopts an event-driven mechanism to trigger the corresponding state transition by monitoring data change events to ensure that the state identification is strictly synchronized with the actual business progress. The update process of the status identification itself is also recorded and audited, forming a closed-loop management system.

[0056] Step 403: Generate an operation log related to updating the business document.

[0057] In this step, a complete business document operation log generation system is built in the intranet, which uses an event-driven architecture to automatically capture various key operation events. The log generation module is deeply integrated into the business processing flow. When the status of a business document changes, the core elements such as the operation type, operation object, and operation context are recorded in real time. The log content adopts a structured storage format and contains the necessary business semantic information to ensure that the log records are both machine-readable and retain sufficient business context. The log update mechanism adopts an incremental recording method to form an operation sequence for continuous operations on the same business document, fully presenting the evolution process of the document life cycle, assigning a unique identifier to each log record, and ensuring that the log records and business operations remain atomic through the transaction mechanism to avoid inconsistencies between business status and log records.

[0058] Step 404: Monitor and analyze the operation log in real time to detect whether there are abnormal operation behaviors or data processing errors, and store the operation log in the intranet.

[0059] In this step, when abnormal operational behavior or data processing errors are detected, a multi-level response process is triggered. The abnormal event is first automatically classified and prioritized, and then appropriate measures are taken according to pre-set policies, including generating alerts, suspending suspicious operations, and triggering manual review. For high-risk anomalies, the emergency response process is automatically initiated to minimize the potential impact. Anomaly detection results are fed back to the log generation module, forming a closed-loop learning mechanism. By analyzing false positives and missed negatives, the detection algorithm and rule base are continuously optimized to improve the accuracy and timeliness of anomaly identification. This adaptive mechanism can effectively respond to the ever-changing business environment and security threats.
