Integrated Tunnel Monitoring System Using Wireless Automated Data Collection Technology
Tunnel accident is apt to become a serious disaster when it occurs. But tunnel construction is being increased rapidly in Korea because tunnel has advantages and usefulness. According to Korean Ministry of Land, Transport and Maritime Affairs, total length of road tunnels was extended from 150 km to 648 km for last decade (333% increased). On the other hand there are several tunnels aged about ...
متن کاملAbstract : Wireless Sensor Network - Based Tunnel Monitoring ∗
In this paper we describe the development and deployment of a wireless sensor network (WSN) to monitor a train tunnel during adjacent construction activity. The tunnel in question is a part of the London Underground system. Construction of tunnels beneath the existing tunnel is expected to cause deformations. The expected deformation values were determined by a detailed geotechnical analysis. A...
متن کاملSiC Resistivity Monitoring; A look at Novel Methods
The market for SiC devices is growing rapidly in Asia, US and Europe. Applications include heterojunction transistors where SiC emitters allow forming high gain, high speed, and radiation hardened devices. SiC is particularly attractive for the power device manufacturers due to its wide band gap and high thermal conductivity. For all applications, the electrical properties of the SiC epitaxial ...
متن کاملGround Monitoring using Resistivity Measurements in Glaciated Terrains
The most common method of monitoring and mapping groundwater contaminants is to extract and analyse a number of groundwater samples from wells in the investigation area. However, there are a number of limitations with this type of point-wise investigation, as it is hard to acquire an adequate picture of a heterogeneous and anisotropic subsurface using a few points. To overcome the limitations o...
متن کاملResearch of Tunnel Construction Monitoring System Based on Senor Information Fusion
With the complex of the tunnel construction, tunnel construction become more and more difficult, in order to ensure the safety of tunnel construction, the paper introduced a kind of tunnel construction monitoring system based on sensor. The system achieves the real-time monitoring of tunnel construction environment including temperature and humidity, gas concentration, dust concentration, locat...
