DESIGN AND IMPLEMENTATION OF EMBEDDING WEB SERVER FOR REAL TIME DATA ACQUISITION AND LOGGING SYSTEM

摘要

Real time data acquisition and logging system allows real time local and remote data acquisition and logging involve in industrial processes. The application runs in a PC with a web server. The interaction with the physical quantity to be measure is done through specific hardware or PC standard interfaces such as the serial port or USB, or by LAN. Terminal mainly includes web database and ADC that acquire signal from transducers and generate its binary equivalent at output lines which interfaced to microcontroller and transmitted to PC and the measured waveforms are shown on LabVIEW, also log this data in standard spreadsheet and upload that spreadsheet over an IP address and will be used for remote monitor or control applications. The test results show that the system meets the accuracy, real-time and reliability of automatic maintenance equipment. And it implements effectively the remote monitoring. The system is designed to be low cost and flexible with the increasing variety data to be acquired.
