摘　　要：为解决传统服务器功耗大、硬件成本高等问题,设计了一款基于嵌入式系统的低功耗服务器。该服务器由STM32F767ZIT6微控制器、SD卡、网络接口模块、电源控制系统等部分组成。基于μC/OS-Ⅲ嵌入式操作系统和LWIP网络协议栈的实时性与稳定性等优点,利用FATFS文件系统,为网络客户端提供文件、网页、应用等服务,实现了数据采集以及多媒体通信等功能。测试结果表明,本服务器连接成功率达99%且可在断电情况下利用UPS可工作近10 h,具有较好的应用价值。In order to solve the problems of traditional server power consumption and high hardware cost,a low-power server based on embedded system was designed. The server consists of four parts:STM32 F767 ZIT6 microcontroller,SD card,network interface module and power control system. Based on the real-time and stability of the μC/OS-Ⅲ embedded operating system and the LWIP network protocol stack,the FATFS file system was used to provide network clients with functions such as files,web pages and applications,so as to achieve functions such as data acquisition,electrical control and multimedia communication. The test results show that,the server has 99% connection success rate and can work for nearly 10 hours with UPS in case of power off. The server has good application value.
