基于Qt的交通雷达监控终端软件设计

Software Design of Traffic Radar Monitoring Terminal Based on Qt

在交通雷达监控终端中,既要正确运行多个任务,又要保证系统的实时性,针对此问题,提出并实现了基于Qt的软件设计方案。首先分析了交通雷达的基本结构和工作原理,并通过研究Qt的实现机制,确立了Qt/E的开发流程,在此基础上建立了Qt的开发环境,对ARM所需完成的功能进行了合理的划分,着重对ARM与DSP的通信、监控界面的设计和ARM的网络通信做了详细的描述。实验测试表明,该设计方案能保证系统的可靠工作以及交通流量信息的安全传输和显示,可应用于交通流量监控领域。

In the traffic radar monitoring terminal,the system should ensure both multiple tasks' proper working and the real-time property. To solve this problem,an software design scheme based on Qt is proposed and realized.The traffic radar's structure,operational principle and Qt's implementation mechanism are firstintroduced.Furthermore,a reasonable division to ARM's functions is doned, and communication between ARM and DSP,GUI design and ARM's ethemet communication are especially described.Experiments demonstrate,this design can make sure system work reliably and the traffic data transfer in security.
