高速铁路路基形变多点检测系统设计

摘要

为了解决铁路路基形变多点检测、远程监控和预警问题，提出了一种基于嵌入式LAMP的铁路路基多点检测系统的设计方案。通过测量路基面竖直方向和水平方向的加速度并运算处理得到路基面的形变量，当其大于设定的阈值时进行报警。系统利用STM32对得到的多点测量信号进行处理，并通过ZigBee网络传输到基于S3C6410的嵌入式LAMP网络服务器。远程用户可通过浏览器远程监控铁路路基面振动幅度变化。经调试证明，系统运行稳定，能够满足设计要求。%In order to solve the problems existing in multi▬point detection, remote monitoring and early warning for railway roadbed deformation, the design strategy of the multi▬point detection system based on embedded LAMP for this application is proposed. Through measuring the accelerations of the subgrade surface in vertical and horizontal directions, and conducting operating and process, the deformation of the subgrade surface can be obtained. When the deformation value is greater than the set point of threshold, alarm signal will be sent out. In the system, the multi▬point measurement signals are processed by using STM32, and transmitted to S3C6410 based embedded LAMP web server through ZigBee network;the remote users may monitor the variation of the vibration amplitude of subgrade surface via browser. The test verifies that the system is running stably, and meets design requirement.
