摘　　要：在开发自动售票机软件系统中,针对系统资源利用不足和性能低下,提出多线程技术。结合自动售票机软件系统的架构和多线程技术的运行机制,用C++实现自动售票机软件系统中设备驱动层和通信层,并给出部分关键代码。该技术的运用使整个软件系统得到很大改善。目前,该软件系统已稳定运行在武汉地铁2号线。For the inadequate use of system resources and poor performance in the development of ticket vending machine software system, multi-threading technology is proposed. Combing with the software system architecture and running mechanism of multi- threading technology, this paper achieves the device driver layer and communication layer of ticket vending machines software sys- tem by C ＋＋ , and gives some key code. The performance of the whole software system has been greatly improved since this tech- nology is used. Now, the software system has been stably operated in line two Wuhan metro.
