WEB SERVER EMBEDDED DATA LOGGER SYSTEM FOR REAL-TIME FIELD MEASUREMENT

摘要

PURPOSE: A web server embedded data logger system for real-time field measurement is provided to remarkably reduce expenses for constructing a system and operating field office, and a number of managers by measuring/analyzing structural behaviors of a bridge in real-time for 24 hours and checking abnormality of the bridge through an embedded web server regardless of time and location. CONSTITUTION: A data logger transmits/receives data through a Linux system. The web server monitors a detection result in real-time through a Java applet by transceiving the detection result transmitted/received from the data logger through socket communication. The data logger comprises a microcontroller/web server(20), and a measurement module(10) formed with a signal controller, a data collector, and a communication module. The measurement module has configuration of an I/O(Input/Output) board for transmitting/receiving a signal to the microcontroller/web server by periodically collecting information of the bridge and adjusting the signal.
