Description

Technical Field

[0001] The present invention relates to the field of financial institution business data processing, and in particular to a provident fund business adaptation method and system based on a self-service terminal. Background Art

[0002] The digital transformation of government services has become a core trend. As a key provider of government services, financial institutions urgently need to expand provident fund service scenarios and enhance their ability to provide convenient services through intelligent devices.

[0003] At the same time, the rapid development of financial technology is driving the intelligent transformation of financial institutions. Smart teller machines (ATMs) and self-service terminals have become key vehicles for extending services. In areas of livelihood, such as provident funds, cross-platform compatibility issues have become a major bottleneck for business implementation.

[0004] Currently, financial institutions' self-service devices are gradually adopting domestically produced "Tongxin" operating systems (such as Tongxin UOS) to respond to the requirements of the "Innovation in Information Technology Applications" industry; while the core business systems of provident fund centers are generally developed based on the Windows architecture. There are significant differences between the two in terms of API interfaces, system call specifications, hardware driver support, etc. For example: because the current self-service devices use the domestically produced "Tongxin" operating system, they are incompatible with the Windows system environment of the provident fund center. As a result, the intelligent teller machine (return slip version) cannot call the ID card reading module, and the non-return slip version cannot realize the printing function. After searching the existing technology, there is no relevant solution to this problem. For example, the closest related provident fund business service technology is the patent literature: CN116308145A discloses a method and device for centralized management of provident fund business. A specific implementation of the method includes: receiving a provident fund business processing request initiated by a user; wherein the provident fund business processing request includes a user number, provident fund business type, and provident fund business request data; querying the business processing flow table according to the provident fund business type, determining the business processing system and business processing sequence corresponding to the provident fund business type, forwarding the provident fund business processing request to the corresponding business processing system in sequence according to the business processing system and business processing sequence, and receiving the returned business processing result; sending the business processing result to the user. This technology receives user requests through the provident fund business centralized management system, queries the flow table according to the business type, and forwards the returned results to the corresponding business system in sequence, so as to centrally handle business; CN107369087A discloses a system for extending the services of a housing provident fund center through a bank. The system includes the following steps: First, a customer applies for a digital certificate at a bank; Second, the customer inserts the digital certificate into a relevant website. The website verifies the validity of the certificate and proceeds to the next step if it is valid; otherwise, an error message is displayed and the system exits if it is invalid or the digital certificate is not inserted; Third, to ensure the security of the website, the system fully utilizes the bank's security system to ensure the integrity of the website and related data and prevent the leakage of related data; Fourth, to ensure the authenticity and validity of the customer, the digital certificate is verified throughout the login and use process; Fifth, relevant business data is entered through the relevant business processing interface established by the bank; Sixth, data exchange is achieved through encrypted connection between the bank's external business processing platform and the housing provident fund center's CSP business processing platform; Seventh, the housing provident fund management center transfers the data received by its CSP business processing platform to the core business processing system. If the business is correct, the data is written to the core business database. This technology is a system for extending the services of a housing provident fund center through a bank. Customers apply for digital certificates to log in, use the bank's security system to ensure security, and encrypt the interactive data between the bank's external liaison platform and the provident fund CSP platform.

[0051] The self-service terminal-based provident fund business adaptation method of the present application can be implemented via a computer program. The computer program for implementing the method of the present application can be written in any combination of one or more programming languages.

The computer program can be executed entirely on the machine, partially on the machine, as a standalone software package, partially on the machine and partially on a remote machine, or entirely on a remote machine or server.

[0052] For S001: Identify the API differences and dependency library incompatibilities between Windows programs and the Tongxin operating system, and build a Tongxin development and testing environment.

[0053] Specifically, during implementation, the Tongxin UOS migration tool is used to scan the dynamic link library (DLL) of the original Windows program, identify Windows-specific system library dependencies such as user32.dll and gdi32.dll, generate a detailed compatibility report, and mark missing API functions and incompatible system calls.

[0054] For the Windows registry operations and COM component calling functions used in the original program, determine their alternative implementation methods in the Tongxin system.

[0055] When building a development environment based on the Tongxin UOS server version, configure the GCC9.3.0 compiler and CMake3.18.4 build tool, install the Qt5.15.2 framework, database driver package, and hardware interface development toolkit in the Tongxin application development SDK, and ensure that the system kernel version (such as Linux5.10) and basic component version of the development environment are consistent with those of the production environment.

[0056] Create a dedicated virtual machine cluster to simulate the actual deployment environment of intelligent teller machines, configure dual network cards to connect to the internal test network and the provident fund center's dedicated network respectively, and deploy lightweight LDAP services and NTP services in the test environment to ensure the normal operation of identity authentication and time synchronization functions.

[0057] Analyze the resource files of the original Windows program, convert the .ico icon into the .png format supported by the Tongxin system, recompile the dialog resources to adapt to the GTK+ interface specifications, establish a cross-platform configuration management mechanism, and distinguish the different configuration parameters of Windows and Tongxin systems through environment variables.

[0058] For S002: Modify the original Windows program code to adapt to the API interface and system call specifications of the Tongxin operating system; specifically, use the Qt5.15.2 framework to reconstruct the front-end interface code, replace the original Windows-specific MFC dialog class with Qt's QWidget derived class, and use Qt's layout manager to reconfigure the interface to ensure consistent visual effects and interactive experience under the Tongxin system.

The pthread thread library is used to replace the Windows thread API, and conditional compilation (#ifdefUOS) is used to achieve compatibility with dual-system environments in the same code base.

[0060] When migrating the database connection module, replace the ODBC interface under Windows with libpq for PostgreSQL or Connector / C++ driver for MySQL, and re-implement the database connection pool management mechanism to ensure stable connection to the provident fund business database under the Tongxin system.

[0061] For the COM component calls in the original program, an intermediate adaptation layer is developed to convert the COM interface into a Qt-based plug-in system, and inter-component communication is achieved through Qt's meta-object system, eliminating the dependence on the Windows COM runtime.

[0062] Reconfigure the log system and use syslog instead of Windows event logs to implement a logging method that complies with Linux specifications while retaining the original log level and format for easier operation and maintenance monitoring.

[0063] Modify Windows-specific registry operations, store configuration data in INI files or JSON files under the / etc directory of the Tongxin system, develop cross-platform configuration management classes, and unify the configuration reading and saving logic of different operating systems.

[0064] Replace the multi-thread synchronization mechanism and use Linux's mutex lock (pthread_mutex) and semaphore (sem_t) instead of Windows's Critical Section and Event objects to ensure thread safety.

[0067] For S003: Develop hardware driver adaptation to implement driver support for the ID card reading module and printer hardware under the Tongxin system; specifically in implementation, for the ID card reading module, first reverse analyze the communication protocol between the original Windows driver and the ID card reader, identify the data transmission format, instruction set and handshake process, develop an adaptation layer based on the USB subsystem of the Linux kernel, and implement device enumeration, connection and data exchange through the libusb library.

[0068] We studied the Windows version of the Ministry of Public Security's ID card authentication API and encapsulated it as a POSIX-compliant dynamic link library. We deployed the driver files to the / lib / modules directory using the FHS specification and implemented automatic device hot-plugging recognition through udev rules. We also developed a multi-threaded management mechanism to ensure UI responsiveness during ID card reading. We also implemented device status monitoring and error handling, automatically resetting and notifying the user when a card reading timeout or device anomaly occurs.

[0069] For printer driver development, we conduct in-depth analysis of the ESC / P and PCL instruction sets of the original Windows print driver, and develop a dedicated back-end program based on the CUPS architecture to implement the parsing, conversion, and transmission of print tasks.

[0070] For PDF-formatted certificates commonly used in provident fund business, we integrated the Poppler library for document rendering and developed custom filters to handle special formatting requirements, such as duplicate printing and multi-page splicing. We optimized print queue management, enabling multi-tasking concurrent processing through the CUPS scheduling mechanism, and developed a print status feedback module to display printing progress and results in real time.

[0071] Implement the printer parameter configuration interface, support the adjustment of paper size and print density parameters, and ensure that the output effect is consistent with the Windows environment.

[0072] Establish a hardware abstraction layer to uniformly manage ID card reading and printing functions, provide a standardized interface for upper-level business systems to call, and shield the differences between different hardware models and driver implementations.

[0073] Develop hardware compatibility testing tools that cover mainstream ID card reader and printer models on the market, and provide customized driver solutions for incompatible devices.

[0074] Create hardware management services in the Tongxin system to implement automatic driver updates and fault diagnosis functions, improve hardware stability through logging and analysis, and ultimately ensure the reliability and performance of ID card reading and printing functions in the Tongxin environment.

[0075] For S004: Control the real-time interaction of dedicated line data between the Tongxin system and the Provident Fund Center Windows system to ensure the transmission of business requests and responses; in implementation, specifically, use the TCP / IP protocol based on the Linux socket API to build a dedicated line network connection, deploy a dedicated line communication service program on the Tongxin system side, and strictly limit data interaction to the specified IP address and port of the Provident Fund Center Windows system through firewall rules.

[0076] Use the Protobuf protocol to serialize business request and response data, standardize the data structures such as personal account information query and provident fund withdrawal application, and compress the data volume to improve transmission efficiency.

[0077] Use the libcurl library to implement HTTP / HTTPS requests to the Provident Fund Center Web Service interface (SOAP protocol), configure SSL digital certificates and a two-way authentication mechanism to ensure the integrity and security of data during transmission.

[0078] Deploy a Redis cache server to locally cache frequently accessed provident fund business data (such as provident fund contribution base and loan benchmark interest rate), set a reasonable cache expiration time and update strategy, and reduce repeated dedicated line requests.

[0079] Develop a data interaction management module to monitor the dedicated line connection status in real time. When a network interruption is detected, the reconnection mechanism is automatically activated and unsuccessful business requests are temporarily stored in the local queue and reissued in sequence after the network is restored.

[0080] Log business request and response data, record request time, parameters, and response result information in detail to facilitate subsequent troubleshooting and business audits, and ensure stable, efficient, and secure data interaction between the Tongxin system and the Provident Fund Center Windows system.

[0081] For S005: Test interface connectivity and verify front-end interaction processes, covering all provident fund business scenarios. Specifically, use the Postman tool to send various business requests, such as personal account information queries and provident fund withdrawal applications, to the provident fund center's Web service interface. Verify that the response status code is 200 under the HTTP / HTTPS protocol to confirm interface connectivity.

[0082] Use the Selenium automated testing tool to simulate user operations. Following the provident fund business process, starting with real-person verification login, execute front-end interactive operations of business scenarios such as personal account information query, deposit details printing, and loan business processing in sequence to check whether page jumps, data display, and button response functions are normal.

[0083] For the ID card reading module call, a simulated ID card device is inserted in the test environment to verify whether the system can correctly obtain identity information and automatically fill it into the corresponding form fields; for the printing function, PDF format certification documents are generated in different business scenarios, and printing instructions are sent through the CUPS printing system to check whether the printer outputs normally and the content format is consistent with the Windows environment.

[0084] Using the JMeter tool, we created a multi-threaded group to simulate 100 concurrent users performing provident fund business queries and printing operations simultaneously. The test lasted for 30 minutes, monitoring the system's response time to ensure it remained within 3 seconds, as well as CPU utilization and memory usage stability. We deployed adapted systems for Tongxin UOS versions 10.3 and 10.4, respectively, to conduct full-business scenario testing. We checked dynamic link library loading, hardware driver compatibility, and system call stability.
