机载固态数据存储器地面测试接口设计方法的研究

The Study of Methods for Designing Interface of Ground Test of Solid state Data Storage on Craft

描述了机载固态数据存储器与地面测试计算机通信接口的硬件设计和相应的软件设计，根据不同的应用要求，采用不同的设计方法，其中包括近距离直接ＲＳ２３２串行通信、长距离电流驱动ＲＳ２３２串口通信和ＲＳ４８５异步通信。介绍了采用ＭＡＸＩＭ公司的ＭＡＸ２３２和ＭＡＸ４８５实现各种通信接口的设计方法。

This paper presents the hardware and software design of interface for communicating ground testing computer with solid state data storage on craft. According to the various requirements of applications,the respective design methods are applicable,including near distance directly RS232 serial communication,far distance current driven RS232 serial communication and RS485 asynchronous communication. This paper introduce the methods for designing the said communicative interface realized by using of MAX232 and MAX485 produced by MAXIM Corporation.
