AB  - This dataset only involves temperature field monitoring data of Xing'anling Tunnel on Suiman Expressway. Mainly includes monitoring the temperature changes of the surrounding rock at the cross-section. The time range of the dataset is from September 2020 to December 2020. During the monitoring process, Pt100A temperature sensors and self-made supporting equipment from Harbin Institute of Technology (temperature measuring rod and temperature measuring chassis) were used. For the imported Pt100A temperature sensor chip, its accuracy can reach up to 0.02 ℃. In addition, each monitoring section needs to be equipped with a wireless bridge, and data is transmitted to the 4G router set at the tunnel entrance through the wireless bridge, achieving wireless transmission through 4G signals. Wireless bridge is a bridge that connects wireless networks, connecting two distant networks through wireless bridging. In recent years, it has been commonly used to replace fiber optic cables and network cables, and even for network data transmission of several kilometers or tens of kilometers. The working principle of a wireless bridge is to use microwave transmission and reception in a designated frequency band for wireless bridging. Since microwave transmission is linear, it is important to ensure that there are no obstacles in the transmission path when using a wireless bridge. The common operating frequency bands are 2.4GHz and 5.8GHz.
