摘要
由于励磁控制器精度和通讯功能要求的提高,DSP这种高精度处理器在电力行业应用逐渐广泛,各种新型的通讯模式也开始在电力系统应用.本文主要讨论以DSP作为主控制器的励磁控制器与流行的数据传输方式USB相结合,改造原来励磁系统主流的单片机+RS232通讯模式,使得无论在通讯速度还是灵活程度上都有很大进步.本文以TI公司的DSP2812和沁恒公司CH375为例,给出了硬件、固件、驱动开发和应用软件编写的基本方法.
Due to the proceeding demand of precision and communication of excitation controller, DSP-high precision processor applies in power energy industry widely, new communication mode also has some application in it. This paper mainly discusses the combination of excitation controller with USB, a prevalent data communication mode, instead of the traditional transmission pattern - SCM ＋ RS232. As a consequence, either communication speed or agility of excitation controller has made a great progress. It also takes the DSP2812 of Co. TI and CH375 of Co. WCH as an example and discusses the hardware solution, firmware solution, the driver software solution, and the application software solution.
