摘要:
针对城市轨道交通信号互联互通测试平台,提出了一种基于PXI(面向仪器系统的PCI扩展)的通用车载适配解决方案。该方案可兼容适配不同厂家车载设备接口需求,可快速适配和切换不同厂家车载设备,支持不同厂家车载设备的共线、跨线功能验证需求。目前,该技术已在重庆互联互通交叉测试平台上应用,并支持完成了相关的共线/跨线测试工作,有力推动了信号系统互联互通技术的发展。

In this paper, a general vehicle on-board controller (VOBC) adaptation solution based on PXI (PCI extensions for instrumentation) for urban rail transit interconnection test platform is proposed. Beneficial and compatible to meet VOBC interface requirements provided by different manufacturers, the solution can quickly adapt and switch different devises, support the common line and cross line functional verification requirements of VOBC from different manufacturers. At present, the technology is applied on Chongqing interconnection cross test platform, and supports the completion of the relevant co-line/cross-line test works, effectively promoting the development of signal system interconnection technology.
