摘要
为解决便携式继电保护测试仪在数据处理及存储方面的相关问题,提出基于USB芯片CH375的解决方案。通过分析CH375的命令集和工作时序,编写了MSP430处理器与U盘的数据通信应用程序。使用结果表明,由此构建的USB接口能够与各种U盘进行数据高速传输和存储。
In order to solve the problem of data process and data storage on the portable relay protection apparatus, the solution based on USB chip CH375 is proposed. Through analyzing CH375 command set and working sequence, the data communication software between MSP430 and U disk is programmed. The test result shows that the USB Interface constructed in this way can transfer and save the data with all kinds of U disk devices at high speed.
