SISTEM MONITORING KENDALI PINTU AIR JARAK JAUH BERBASIS BORLAND DELPHI 7.0

Abstract

The design of program maker in system monitoring long distance flood gate rein based on borland delphi 7.0. data delivery system based on principle fsk (frequency shift keying). this ware can be used to various need among others monitoring level water height, flood gate condition for distribution plta and other as it. This system consists of hardware and software. hardware consists of series optocoupler, electrode censor series, series mikrokontroler at89s51, series modem fsk with xr-2206 and xr- 2211. software uses programming language assembly reads 51 and borland delphi 7.0. procedure from this tool is that is when mikrokontroler get data input from optocoupler and electrode, so mikrokontroler will open and close flood gate automatically. then data sent according to serial and memodulasi according to fsk and radiated to use transmitter fm. data then accepted by receivers fm in centre station and mendemodulasi according to fsk will be digital data later on be cultivated and displayed at computer. From watchfulness that done got measurement result from two stations. testing result that measurement at object station equal to at computer.
