摘要
隧道在地铁长期运营后会出现横向与纵向上的变形.为保证地铁在隧道空间中运行的安全性,必须对隧道进行可靠的健康监测.提出将嵌入式Linux应用于隧道的纵向变形监测系统中,该方案包括了嵌入式终端的硬件组成与软件设计,通过自定义串口通信协议实现主机和多个嵌入式终端之间的命令控制和数据传输,并提供了寻址、差错检验和一定的冲突检测能力.
In general,the horizontal and vertical deformations occur after a long-term subway operation.To ensure the subway operational safety,it is necessary to implement the health monitoring on tunnels.In this study,a LinuxTM-embedded vertical deformation monitoring system is proposed in terms of hardware configuration and software programming.By self-defining the serial communication protocols,the command control and data transfer between host PC and embedded terminals are realized to provide such functionalities as address search,failure measurement and conflict detection.
