摘要
出租车监控系统主要功能为录音和拍照,并把采集的数据存储到本地存储器,可以通过SD卡导出存储的数据。本监控系统使用ST公司的STM32F103ZX为主控MCU,通过SDIO接口与标准SD卡和microSD卡进行通信,实现了大容量数据的存储和拷贝。本文给出了系统硬件结构图,详细探讨了SDIO驱动以及FatFs文件系统的移植和应用方面的软件设计。该方案传输速度快、兼容性好、可靠性高的优点,具有广阔的市场应用前景。
The main function of Taxi monitoring and control system is recording and taking photos, and storing the collected data to the local memory, and the stored data can be exported through the SD card.The monitoring system is realized by connecting STM32F103ZX of ST with SD card and microSD card though SDIO bus, implementing the functions of large capacity of data storage and copy.The hardware structure of the monitoring system is presented, how to designed SDIO driver program and transplant FatFs file system is discussed in details.The SD card has a high transmission speed, standards compliant and reliability, so it has a large board market application prospect.
