基于GSM-R的青藏铁路冻土地温自动监测系统

Automatic Permafrost Temperature Monitoring System of Qinghai-Tibet Railway Based on GSM-R Network

根据青藏高原永久性冻土及高原恶劣的环境条件等特点,集传感器技术、数据采集技术及计算机与通信技术于一体,研制开发一套性能稳定可靠、自动化程度高、操作简便的青藏铁路长期地温自动监测系统。该系统实现了青藏铁路多年冻土路基的多断面多测点地温数据高精度的自动采集、远程自动传输和自动分析处理功能。该系统自安装完毕后,运行状况良好,采集的地温数据为青藏铁路多年冻土区路基稳定性分析奠定了基础,并为路基病害整治和铁路安全运行提供科学依据。

In consideration of the Qinghai-Tibet Railway permafrost and most adverse environment, the automatic long-term ground temperature monitoring system was developed for the Qinghai-Tibet Railway by integration of sensing technology, data acquisition technology and computer and communication technology. The monitoring system is reliable, highly automatic and easy to operate. It has realized the functions of automatic acquisition of multiple cross-section multipoint ground temperature data, automatic remote transmission and automatic analyzing and processing. It has been working well since mounting and commissioning. The reliable and true ground temperature data serve analysis of stability of the Qinghai-Tibet Railway permafrost subgrade and provide a scientific basis for subgrade disease repair and safe operation of the Railway.
