为满足利用信号试验车进行在线测试的需求,建立铁路信号测试系统的信息流模型,提出符合COTS(Commercial Off-the-Shelf,即成熟的商品化产品)、信息融合、信息统一、模块化等指导原则的车载测试系统架构。系统硬件主要采用PXI/CompactPCI数据采集系统、PDA、GPS定位设备、无线局域网设备等;软件采用RT实时操作系统,综合应用多线程、数据库和虚拟仪器等软件开发技术完成。系统已经在实际的铁路信号测试中得到应用,并且满足各方面需求指标,应用前景广泛。
In order to meet the need of on-line test of signal test vehicle, the information flow model of railway signal test system is established, and the information flow model which meets the requirements of COTS (Commercial Off-the-Shelf), information fusion, information unification and modularization Guiding principles of automotive test system architecture. The system hardware mainly uses PXI / CompactPCI data acquisition system, PDA, GPS positioning equipment, wireless LAN equipment, etc .; software RT real-time operating system, integrated application of multi-threading, database and virtual instrument software development technology to complete. The system has been applied in the actual railway signal test, and meet the various needs indicators, the application of a wide range of prospects.
