摘　　要：为有效解决现装甲特种车辆信息控制单元占用空间较大、传输功能单一等问题,设计了一种基于STM32的可双向操作数据存储模块.该模块以USB接口芯片CH378为核心进行USB主从机信息传输,以STM32F103为核心处理器搭建主控系统;设计了一种主、从机模式切换电路,实现模块虚拟磁盘工作模式和外接USB存储设备工作模式的自动切换.通过对模块各工作模式进行测试,验证了该模块功能实现的可行性与可靠性.该模块体积小、方便操作,为装甲特种车辆测试数据传输系统的应用与维护提供了便利.In order to effectively solved the existing armored special vehicle information control unit occupies a large space,transmission function single and other problems,designed a STM32-based bi-directionally operable data storage module.The module uses the USB interface chip CH378 as the core for USB master-slave information transmission,and the STM32F103 as the core processor to build the master control system;a master and slave mode switching circuit was designed to realize the automatic switching of the module's virtual disk working mode and external USB storage device working mode.By testing each working mode of the module,the feasibility and reliability of the module function is verified.The module is small in size and easy to operate,which provides convenience for the application and maintenance of the test data transmission system of armored special vehicles.
