Using Wireless Sensor Network on Real-Time Remote Monitoring of the Load Cell for Landslide
Abstract:This study designed a real-time remote monitoring system for installing the load cell of tieback anchor as well as the rain gauge in the landslide area. The architecture of proposed system consists of four tiers: (1) sensors, (2) infrastructure nodes, (3) the gateway, and (4) Web interface. Based on the embedded system development, an amplifier was considered to enlarge the voltage of load cell to fit in the transmission range of mote at each node of the wireless sensor network (WSN). For efficiently measuring the loads of the tieback anchor, a calibration equation was employed to calculate the load according to the corresponding voltage in the load cell and the amplifier. Multihop communication among the WSN was utilized to transmit measured data of the load cell from the motes to the gateway. Through Web interface, the socket receiver, database management, and monitoring interface were incorporated at the backend server to monitor, record, and perform the real-time information of landslide for achieving the initial approach.
