铁路路基与铁轨沉降数据采集系统的设计

Design on Railway Roadbed and Track Sedimentation Deta Collection System

针对目前铁路路基的现状,设计和开发一套铁路路基与铁轨沉降数据采集系统。该系统由沉降数据采集器、数据传输网络和远程控制中心组成。采集器通过One-Wire总线采集沉降传感器数据,通过无线通信ZigBee组成一个链状网络传输数据,由一特定采集器将数据存储在SD卡里并将所有数据定期通过GPRS发送到远程控制中心。通过远程控制中心对沉降数据客观的统计和分析,预测工后沉降,在路堤填筑过程中,指导控制填土速率;并在运营期间指导轨道参数调整和养护维修,确保列车平顺、安全运营。

According to the current status of railway and roadbed,a set of Data Collection System for railway roadbed and track sedimentation was designed and developed.The System consisted of sedimentation data collector,data transmission network and remote control center.The data collector collected the sensor data through One-Wire bus.And then,the data,through ZigBee,composed a chain network send data.Finally,it was by a particular collector that the data was stored in a SD card and all the data were regularly sent to the remote control center by way of GPRS.The objective statistics and analysis of the sedimentation data in the remote control center could help forecast the post-construction sedimentation and guide the control of filling velocity.Also,the statistics and analysis contributed to the guidance of rail parameters adjustment and maintenance during the operation to ensure smooth-going and the safe operation.
