摘要
针对RS-232C通讯存在的速度瓶颈问题,以Philips公司的USB设备接口芯片PDIUSBD12为例,结合数字信号处理器应用开发平台,将USB通讯应用在励磁调节器仿真测试系统中,提高系统的数据传输率。仿真测试结果表明,采用USB通讯接口比RS-232C的数据传输率快,能够满足系统实时仿真的要求。
This paper presents USB interface based on DSP and PDIUSBD12 to overcome the shortcoming of the transfer rate limitation in RS-232C.Its application in the excitation regulator simulation and measurement system is described in detail.The experiments indicate that using USB can get a much higher data transfer rate than RS-232C to satisfy the system real-time simulation requirement.
