Huaqi Passenger Information Management Software V2.0

A new generation cloud-native architecture enables business agility and growth. Our management software adopts a cutting-edge microservices architecture and cloud platform deployment solution, aiming to completely resolve the inherent rigidity and risks of traditional monolithic systems. By decomposing a bloated monolithic application into a set of small, independent, autonomous specialized services, each service can be independently developed, deployed, and elastically scaled, thereby greatly enhancing the system's flexibility, reliability, and maintainability.

Subsystems and Main Functions

System Features

01
Operating environment: Meet the stringent requirements for autonomy, controllability, and information security in critical sectors, based on domestic operating systems.
Core components: Utilize domestic databases as the business data storage engine, forming a fully domestic foundation for data management and application.
02
System services: Integrate RabbitMQ message middleware to achieve decoupling and asynchronous communication between services; utilize Docker containerized deployment to ensure environment consistency and improve operational efficiency.
System support: Equipped with ntpd time synchronization service to ensure precise system clock synchronization, providing a reliable time reference for the entire business chain.
03
Base library support: Use the Boost library for efficient time processing, regular expression matching, file system operations, and multi-thread control.
Data interaction: Utilize Rapidjson for JSON parsing, Curl for network transmission, and Restbed for building RESTful interface services.
Security verification: Integrate LibBSD to implement MD5 verification mechanisms, ensuring the integrity of data transmission and storage.
04
Development environment: Use Eclipse+GDB for C++11 standard development under domestic operating systems, fully leveraging native compilation performance.
Version management: Utilize VisualSVN for code version control, combined with the GCC 4.9.3 compiler to build a stable and reliable compilation toolchain.
05
Core components: Equipped with independently developed Media Server software to meet professional-grade audio and video processing requirements.
Base framework: Integrate the Waxberry development library, providing common functional modules such as log management, enhancing code reusability and system maintainability.
