一种E1多模式数据仿真测试平台的设计与实现

摘要

Aimed at the current E1 simulation and testing platform only simulating simultaneously at single-mode E1 data, a design of multi-mode parallel processing E1 data to simulation testing platform is put forward. The hardware of simulation platform, work principle, upper controlling software and design of low-level driver are studied. The simulation and testing platform is used to simulate El data stream in communication network, provides signal source for production, testing, research and development. Testing results show that the platform has a strong multi-mode in parallel data transmission capabilities, good availability and practical application,the platform strongly satisfies the needs of data acquisition devices testing.%针对目前E1仿真测试平台只能仿真单工作模式数据,提出了一种并行处理多工作模式数据平台的设计方法.研究内容主要包括平台硬件、工作原理、上层控制软件和底层驱动程序的设计.该仿真测试平台用于仿真通信网E1数据流,为生产、测试、研发提供信号源.测试结果表明,该平台具有较强的多工作模式数据并行传输能力,具有良好的实用性和应用价值,极大地满足了E1数据采集设备测试的需求.
