摘　　要：针对目前CBTC测试平台中各仿真子系统存在接入难和复用性差等问题,以车辆仿真子系统为例,设计一种基于Linux的车辆仿真子系统接口适配器。首先根据接口适配器的通用性,提出硬件接入层和软件逻辑层的设计模型;然后在硬件接入层部分完成接口适配器和车辆仿真子系统与CBTC测试平台之间的信息配置和交互过程;其次在软件逻辑层部分,设计基于Linux平台的BSP驱动开发流程,实现信息转换和传递功能。最后将车辆仿真子系统的接口适配器接入到CBTC测试平台中,通过使用试验线的数据以及动车组数据进行调试,研究结果表明:接口适配器输出的速度脉冲误差在2%以内,满足CBTC测试仿真平台的性能要求。For the simulation subsystems of the current CBTC test platform, there are problems such as difficult access and poor reusability. By taking the vehicle simulation subsystem as an example, a Linux-based vehicle simulation subsystem interface adapter was designed. First, according to the versatility of interface adapter, the design model of hardware access layer and software logic layer was proposed;second, in the hardware access layer part, the information configuration and interaction process between the interface adapter and the vehicle simulation subsystem and the CBTC test platform were mainly completed. In the software logic layer, the BSP driver development process under the Linux platform was devised, which completed the information conversion and delivery functions. Finally, the interface adapter of the vehicle simulation subsystem was connected to the CBTC test platform, and test line data and EMU data were used for joint adjustment. The results show that the speed pulse error of the interface adapter output is within 2%, which satisfies the performance requirements of the CBTC test simulation platform.
