UNDERGROUND CABLE ROUTE MARKER AND MANAGEMENT SYSTEM OF UNDERGROUND CABLE ROUTE MARKER USING INFORMATION RECOGNITION DEVICE BASED ON HYBRID ENERGY HARVESTING

摘要

The present invention relates to an underground cable route marker and a management system of the underground cable route marker, using an information recognition device based on hybrid energy harvesting. A technical subject matter of the present invention relates to an underground facility management system and a method of acquiring information. More specifically, the method includes: storing information of an underground cable route marker into a transmission unit of an information recognition device such as an RFID tag, NFC, Bluetooth and the like; attaching an energy harvesting module such as a piezoelectric sensor and a solar cell to the underground cable route marker attached thereto with the information recognition device so as to store energy acquired from the energy harvesting module; and supplying power to the transmission unit of the information recognition device so as to allow a user to read information by using a receiver of the information recognition device for the underground cable route marker when necessary. Accordingly, information of underground facilities is easily shared through access to an Internet homepage, so that repeated works of investigating the underground facilities at each construction, and big accidents resulting from construction defects caused by changed information unknown to the user are prevented in advance.;COPYRIGHT KIPO 2017
