RANCANG BANGUN SISTEM PENGONTROLAN KECEPATAN MOTOR AC SATU FASA JARAK JAUH MENGGUNAKAN JARINGAN WI-FI 2.4 GHZ dan MIKROKONTROLER AT89S51

Abstract

Planning done and motor speed controlling system realization ac long distance uses network WIFI 2,4 GHZ and mikrokontroler AT89S51. this tool can controls motor ac one fasa without having to see to field. This system consists of hardware and software. hardware consists of series optocopler, series DAC 0808, series mikrokontroler AT89S51, series penggeser fasa with ic TCA 785, series scr with menyplay lcd. software uses programming language assembly reads 51 and borland delphi 7.0. work system from tool that is when mikrokontroler get data inputan from outside, so data will be used as inputan in penggeser fasa, but previous data is changed beforehand to analog form in series dac. input series penggeser fasa shaped analog tension in unit volt, while output from series penggeser fasa shaped fasa wave that used for trigger gate SCR, so that SCR can functioned as motor speed control ac. result or value from this speed controlling displayeds in lcd and computer. In this watchfulness produce ware that can controls big the so small motor speed ac one fasa. smaller inputan that given so fasa scr lock with corner smaller so that motor faster rolling.
