摘要
介绍了一种基于嵌入式技术、无风扇、无硬盘、高可靠性通信管理机的硬件系统和软件设计。该装置具有2个以太网接口,多路可选配的标准异步串行接口,实现了异种网络之间的通信协议转换和数据收集转发功能。使用高性能、低功耗的嵌入式硬件平台,操作系统选择裁减的Linux,合理的分层分布软件设计达到长期稳定运行的要求。
A new designed communication controller based on the embedded technology, no fans, no hard disk is proposed. It has two Ethernet interface and multi-channel standard asynchronous serial interface. It has realized protocol transformation between the heterogeneous network communication and the data collection repeater. The communication controller uses the hardware with high performance and low power consumption. It also uses reduced Linux operating system and reasonable lamination distribution software design. The device is achieved the request of long-term stability operation.
