A METHOD AND A DEVICE OF MEASURING VARIETY ENVIRONMENT STATUS FOR THE ENGINEERING AND CONSTRUCTION SITE

摘要

PURPOSE: An instrument for measuring environmental change of civil construction site is provided to determine changes around the site to protect damage and accident of construction works and to ensure safety management by measuring and transmitting signals detected from sensors installed in the site by wireless. CONSTITUTION: The instrument comprises ladder type stand comprises sensors (110) to output signals corresponding to various environmental changes and/or displacement amounts; matching part (120) to input the signals from the sensors; ADC (130) to convert the analog signals from the matching part into digital signals; a first wireless part (140) to transmit the frequency signals by receiving the environmental signals from ADC and converting them into the frequency signals of 424MHz or 447MHz; a second wireless part (145) to receive the frequency signals from the first part and transmit control signals corresponding to the received signals; a control part (150) to receive various signals of the construction site from the second part, to identify the signals for corresponding sensors, to compensate the error signals and to amplify them into determined level; and an operation storage part (160) to generate alarm and record when the environmental signals are out of the desired range.
