Ground Temperature Monitoring Data Transmission Scheme Based on Beidou Short Message
High ground temperature and frozen soil make the construction and operation of railway,highway and subgrade more danger-ous.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 Bei-dou 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.
