MEASUREMENT SYSTEM OF CIVIL ENGINEERING STRUCTURE USING WIRELESS TRANSMISSION TECHNOLOGY

摘要

PURPOSE: A measurement system of a civil engineering structure using wireless transmission technology is provided to reduce measurement cost by transmitting a sensed signal in a wireless manner. CONSTITUTION: A sensor interface(1) is connected to a gauge-type sensor such as a strain system, a displacement system, a load cell, and various sensors such as an accelerometer and a speed meter. A transmitter controller(2) is comprised of an AD(Analog-to-Digital) converter. The AD converter digitizes an analog signal in order to transmit it in a wireless manner. A transmitter(3) transmits the digital signal. A receiver(4) receives the digital signal transmitted from the transmitter(3). A receiver controller(5) controls the receiver(4), demodulates a signal, and performs a data conversion. Data storages(6,7,8) such as a computer store data and analyzes it.
