Based On The Lonworks Field Bus Technology And Gprs Engine Room Power Monitoring System

With the development of electronic technology , technology of the computer and communication technology, wireless communication technology and on-the-spot bus technology get swift and violent development too, combining the two becomes an inevitable trend. This text under the background , combine one distribution system of computer lab is it control subject of in real time to go on just, adopt the advanced electric energy to measure the technology of the chip, the electric monitoring system of carrying on the computer lab based on LonWorks on-the-spot bus technology and GPRS is studied.Through adopt special-purpose high-accuracy electric parameter gather chip and GPRS wireless Modem design collect three-phase electric parameter measurement this text, the figure is input and measured, the figure is exported and controlled in the integrative distribution voltage transformer long-range network monitoring terminal station. This text explains its realization course from the hardware and software respectively.Chapter one of thesis has introduced the current situations of the classification of the monitoring system and domestic and international electric monitoring system development of computer lab on the whole, is it use LonWorks on-the-spot bus technology and GPRS network as computer lab electricity and real-time transmission media of monitoring system to propose on this basis. Chapter two introduced LonWorks on-the-spot bus technology. . Introduce GPRS at the foundation , communication of principle , is it is it adopt LonWorks on-the-spot bus technology and superiority , GPRS of technology the present stage to analyse to proceed from technological angle. Chapter three recommended the distribution of...
