摘　　要：高地温、冻土使铁路、公路等工程隧道、路基施工及运营存在较大的安全隐患,地温数据是地温场机理研究的关键因素,远程无人监测手段是获取长周期地温数据的最佳手段。现有传输技术在无人区难以开展,无人区的远程数据传输是实现远程监测的关键因素,采用北斗短报文技术实现远程通讯功能。由于民用北斗系统的限制,使得通讯不可靠,通过自定传输通讯机制的方法解决了无通讯回执的问题;通过数据组包及压缩的手段解决了北斗短报文系统传输空间小、间隔时间长导致的传输时间长,低传输成功率的问题。通过某铁路的冻土监测孔实践表明:设计的传输方案使得传输成功率在85%以上,获得了大量的地温监测数据,为无人区大数据远程传输提供了一种新的手段,为铁路方案设计提供了翔实的数据支撑。High ground temperature and frozen soil make the construction and operation of railway,highway and subgrade more dangerous.Ground temperature data is the key factor in the mechanism research of ground temperature field,and remote unmanned monitoring means is the best means to obtain long-term ground temperature data.The existing transmission technology is difficult to carry out in the no-man's land,and the remote data transmission in the no-man's land is the key factor to realize the remote monitoring.The Beidou short message technology is used to realize the remote communication function.Due to the limitation of civil Beidou system,the communication is unreliable,so the problem of no communication receipt is solved by self-determined transmission communication mechanism,and the problems of long transmission time and low transmission success rate are solved by data packet and compression.The practice of frozen soil monitoring hole in railway shows that the designed transmission scheme makes the transmission success rate more than 85%,and a large amount of geothermal monitoring data is obtained,which provides a new means for the remote transmission of big data in no man's land,and provides detailed data support for the railway scheme design.
