Tandem type network construction method for tunnel remote on-line remote-measuring system

The invention discloses a tandem type network construction method for tunnel remote on-line remote-measuring system. The tandem type network construction method is suitable for remote on-line remote-measuring network construction of tunnel engineering such as water conservancy and hydropower and transportation. The tandem type network construction method comprises the following steps: in tunnel excavation process, based on the monitoring requirement, in the tunnel excavation direction, burying groups of sensors in sequence in tunnel surrounding rock at the rear of a target monitoring section after the first spray of concrete; allowing each group of sensors after installation to connect with channel processors of corresponding area through signal lines respectively, and finally in series connection with channel processors of each area through bus cables, so as to form a linear network access monitoring center to achieve remote real-time collection, transmission and reception of data. The tandem type network construction method for tunnel remote on-line remote-measuring system gives full consideration to the linear structural characteristics of the tunnel, can form an effective combination with tunnel layer-by-layer excavation process, reduces the interference of monitoring work to construction work, is beneficial to improving the transmission and collection capability of the monitoring system to the monitoring data and reduces the damage rate of the instrument, and the system is easier to expand.
