[0002] With the development of informationization and digitization technology, the management and operation methods of power grid enterprises in auditing work have gradually changed. Traditional auditing systems have problems such as low efficiency, difficulty in data interaction, etc., especially in the auditing project field work of power grid enterprises. The current auditing system mainly relies on ERP system, PMIS system, etc. to carry out work, but its query efficiency is low, the comparative analysis function is weak, and it can only realize post-result auditing, and cannot realize risk intelligent identification, analysis and early warning functions. In addition, the existing system has slow data updating speed, and the implementation effect of part of the function points is not good, which is difficult to meet the centralized management and rapid response demand of power grid enterprises on large-scale engineering projects.

[0003] In specific application scenarios, the auditing work of power grid enterprises needs to face a large number of engineering projects, and the time is urgent, and the auditing task is heavy. The man-machine interface of the existing system is not user-friendly, the audience range is narrow, and it cannot meet the requirements of field visualization, and it lacks real-time monitoring and intelligent management means for the implementation process of the project. This leads to the accuracy and timeliness of the auditing results being affected, and reduces the overall efficiency and quality of the auditing work.

[0004] To solve the problems of low efficiency and inconvenient data interaction in the field work of power grid enterprise audit projects, the prior art discloses an internal auxiliary auditing method. The method performs mobile auditing work through a mobile terminal, realizes synchronization of the mobile terminal and the internal network server of the audit record through the power grid wireless private network VPN encryption mode, receives the audit record transmitted by the mobile terminal through the internal network server, and performs identification, conversion extraction and collection. The collected data is synchronized to the internal network server in real time. The audit record collected in real time by the mobile terminal and the workflow are combined to automatically generate an audit draft, an audit summary and an audit report. The audit results are analyzed to realize multi-dimensional problem analysis and value mining of the audit report. Although this method realizes audit recording in multiple scenarios, multiple modes and at any time and any place, improves the efficiency and information security of the audit work, but there is still room for improvement in the intelligent identification and understanding of audit problems and policy basis during the audit process. The prior art relates to a multi-terminal project declaration system. The system includes an internal network server, an internal network router, a network gate, an external network server, an external network router and a plurality of terminals. The internal network server and the external network server with a specific structure are set to work cooperatively, and the network gate synchronizes the project declaration information in the internal and external network database servers. The system supports project declaration data filling on mobile terminals and single machine terminals, and multiple terminals can cross edit, supports locking function of migration in / out to ensure that only one terminal is editing at the same time, prevents data loss caused by cross update of different terminals, and improves the efficiency and accuracy of declaration. However, the system still has room for improvement in the optimization of audit information input and saving and the flexible satisfaction of different business needs and processes.

[0044] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0045] In order to make the above purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail in the following with reference to the drawings and specific embodiments.

[0046] In an exemplary embodiment, as shown in Figure 1 An audit system for a power grid enterprise is provided, which comprises terminal hardware, a mobile phone APP module, an external network application server, an internal network application server, an internal network database server and a file server.

[0047] The mobile phone APP module is loaded on the terminal hardware. The terminal hardware is used for on-site auditing according to an auditing task, real-time data entry and information acquisition, and uploading the entered data and acquired information to the internal network application server. The terminal hardware such as a mobile phone, a tablet computer and the like is specially designed for on-site work of power grid enterprise auditing, has high performance processing capability and strong and durable characteristics, and can adapt to various complex on-site environments.

[0048] The mobile phone APP module is connected with the external network application server. The mobile phone APP module is used for providing mobile access function and sending an external user access request to the external network application server.

[0049] Specifically, the mobile phone APP module communicates with the external network application server through a secure HTTPS protocol.

[0050] The outer network application server is used for processing external user access requests, providing Web services and API interfaces, and supporting mobile APP modules and remote user access; the outer network application server requests data processing and business logic execution from the inner network application server to ensure the security of internal data.

[0051] The inner network application server is used for processing requests of internal users and performing business logic processing and internal data interaction.

[0052] The inner network database server is connected with the inner network application server; the inner network database server is used for storing audit-related data and performing addition, deletion, modification and search operations of the audit-related data through the inner network application server; the audit-related data includes audit records, user information and reports.

[0053] Specifically, the inner network application server and the inner network database server communicate through a database connection protocol.

[0054] The outer network application server and the inner network application server realize the interaction between the enterprise inner network and outer network, guarantee the real-time transmission and processing of audit project field data, and ensure the security and timeliness of the data.

[0055] The specific communication process is as follows:

[0056] Through data transmission to the intermediate cache area, the connection between the information source and the intermediate cache area is established to establish an initial connection. The information source sends data to the intermediate cache area, and after the data transmission is completed, the connection between the information source and the intermediate cache area is physically disconnected to prevent unauthorized access or tampering of the data during transmission. The intermediate cache area receives and temporarily stores the data to ensure the integrity and confidentiality of the data in this area. Before the data is transmitted to the destination, the intermediate cache area may perform security checks such as virus scanning and data integrity verification. Once the data processing in the intermediate cache area is completed, the transmission channel between the intermediate cache area and the information destination is connected.

[0057] The intermediate cache area transmits data to the information destination (such as an outer network application system). After successful data transmission, the connection between the information source and the intermediate cache area is physically disconnected. At this time, the connection between the intermediate cache area and the information destination is also disconnected.

[0058] The file server is connected with the inner network application server; the file server is used for storing files and performing file uploading, downloading and sharing; the files include audit reports, pictures and documents.

[0059] Specifically, the intranet application server communicates with the file server through a network sharing protocol (such as SMB or NFS).

[0060] As a specific embodiment, the mobile phone APP module includes: a workbench, a message unit, a project unit, a wisdom review unit, and a wisdom library unit.

[0061] The workbench is configured to provide daily office functions to facilitate the efficient handling of daily affairs by the audit personnel on site; the daily office functions include, but are not limited to: task management, schedule arrangement, and message notification.

[0062] The message unit is configured to perform real-time transmission and communication of different forms of messages to ensure efficient communication and cooperation among members of the audit team; the different forms of messages include: text, picture, audio, and video messages.

[0063] The message notification mainly uses a message queue (such as Kafka, RabbitMQ, etc.) to handle asynchronous message transmission; when a new message is generated, the message is pushed into the message queue, and the relevant processing module can consume the message from the queue to achieve decoupling and asynchronous processing. When the message is processed in the message queue, the push notification service can push the message to the terminal user's device (such as a mobile phone APP or a webpage) in real time through technologies such as WebSocket, APNs (Apple Push Notification service), or Firebase Cloud Messaging (FCM). The main message push includes: approval notification, pending approval notification, plan expiration notification, and audit personnel message intercommunication, etc. A message notification center is provided on the front-end interface (such as a webpage or a mobile phone APP), and the user can view all notifications, mark them as read, and reply to the approval.

[0064] The project unit is configured to manage the audit project to ensure that each link of each project can be effectively managed and controlled; the management of the audit project includes: project establishment, progress tracking, and document management.

[0065] The management of the audit project is to clearly define the objectives and coverage points of the audit project in the early stage, communicate with relevant parties, determine the key areas and specific needs of the audit. The project proposal needs to be approved by relevant personnel, including the audit supervisor, group leader, etc., to ensure the necessity and feasibility of the project. After approval, the roles of each participant in the project are clearly defined, and the project is distributed to the audit supervisor, group leader and team members, and their responsibilities and tasks are determined. Track the progress through project management tools, regularly check the completion of tasks to ensure that the project is progressing according to plan. Establish document management standards to ensure that all audit-related documents (such as audit plans, work drafts, reports, etc.) are organized according to the specified format and requirements. After the completion of the project, the audit results are summarized, and the achievement of the project objectives and the effectiveness of the audit are evaluated.

[0066] The wisdom unit is used to conduct intelligent audit analysis using artificial intelligence technology, and provides audit models, intelligent decision support and risk warning functions to improve the scientificity and accuracy of audit work;

[0067] The wisdom unit is used to build an audit knowledge base using artificial intelligence technology, support the query and reference of audit-related laws, regulations, policy documents and historical audit cases, and facilitate auditors to quickly obtain the required information.

[0068] The audit knowledge base stores the experience and data of past audit projects, facilitating auditors to query and learn, and using the AI question and answer function, auditors can quickly obtain the required information and guidance, improving work efficiency. It can also help to process the key issues ignored in the interview, identify the doubtful questions in the interviewee's answers, and analyze the inconsistencies and emotions of the interviewee's answers. Scene applications; can automatically review contracts, invoices and other documents, identify potential compliance issues or data errors, and reduce the workload of manual review.

[0069] The data model of the audit can automatically analyze transaction data according to the set parameters, identify suspicious data of abnormal transactions or behaviors, and prompt the auditor to further investigate. The data model can analyze historical data to identify potential high-risk areas or activities, helping auditors focus on areas that need more attention.

For example, existing data can be processed through expressions or algorithms to generate new data views in real time. When designing the database table, define the basic fields (such as ID, name, date, etc.), and add the definition of the virtual field if necessary. Design the relationship between tables to ensure that the tables involved can be associated through foreign keys, which facilitates subsequent dynamic querying and statistics. By using parameterized queries and stored procedures, users can specify which virtual fields need to be calculated at runtime, thereby dynamically generating results. Combine data mining and analysis tools to allow users to generate dynamic reports based on virtual fields and perform multi-dimensional analysis.

[0073] The multi-terminal project declaration module is used for mutual cooperation of the intranet application server and the extranet application server, supports project declaration data filling on multiple terminals, ensures data synchronization and consistency, and improves the efficiency and accuracy of declaration.

[0079] Data compression component is used to reduce the volume of data to improve transmission speed and save bandwidth - use efficient compression algorithms (such as Gzip, LZ77, etc.) to compress data, reduce data transmission.

[0080] Data storage component is used to store the transmitted data in mobile terminal and backend system for subsequent access and management - use local database (such as SQLite) to store temporary data in mobile terminal, improve access speed and offline ability.

[0081] Data exchange component is responsible for data interaction between mobile terminal and backend ERP system, mainly through RESTful API or GraphQL interface, providing standardized data exchange way for communication between different systems.

[0082] Specifically, the voice recognition technology module specifically includes: collection and arrangement unit, data preprocessing unit, text conversion unit, voice recognition unit and information retrieval unit;
