Design of software structure for central control unit based on QNX OS

摘要: 在对CRH3A型城际动车组中央控制单元功能需求分析的基础上,提出一种基于QNX操作系统的应用软件结构设计。该结构将软件按功能划分为多个进程和线程,通过信号量机制实现线程间的数据传输和管理,提高软件的执行效率和可靠性。

Abstract: With the analysis of function requirements for central control unit of CRH3A EMU, a software design structure was proposed based on QNX OS. The design structure divided software into several processes and threads. The data transmission and management between threads were implemented by the semaphore mechanism to optimize efficiency and reliability of the software.
