WIRELESS SENSOR SYSTEM FOR SURFACE TEMPERATURE MONITORING OF THE UNDERGROUND TUNNEL CABLE JOINT

摘要

PURPOSE: A monitoring system using a wireless sensor of a surface temperature of a underground tunnel cable joint is provided to easily construct a wireless communication network at low costs at a place where a wire communication infra is not installed. CONSTITUTION: A surface temperature measuring node(100) measures a surface temperature of an underground tunnel cable joint by three temperature sensors(110). A relay node(200) receives surface temperature data. The relay node measures an air temperature. A collecting node(300) delivers data of the relay node through an internet. A gateway(400) receives measurement information from the installed collecting node. A measuring server(500) provides processed measurement information to a manager terminal and a web monitoring screen.
