Abstract

 

ABSTRAK

Repeater SCADA (Supervisory Control and Data Acquisition) merupakan suatu sistem yang berfungsi sebagai penghubung antara RTU (Remote Telemetry Unit) dengan MTU (Master Terminal Unit) jika memliki jarak yang jauh. Repeater SCADA terdiri dari antena, amp transmit, mini kontrol dan radio telemetri 433 MHz.

RTU diatur pada frekuensi 433 MHz sedangkan MTU pada frekuansi 440 MHz. Data yang dikirimkan dari RTU ke MTU berupa parameter listrik.

Hasil yang didapatkan antena memiliki VSWR 1,23 untuk frekuensi 433 MHz dan 1,32 untuk 440 MHz, penguatan stabil amp transmit 3 Watt, Rx level repeater -56,38 dB, SOM (System Operating Margin) 60,62 dBm, dan sistem ini dapat berkomunikasi sejauh 3,9 Km.

ABSTRACT

          SCADA Repeater (Supervisory Control and Data Acquisition) is a system that serves as a liaison between the RTU (Remote Telemetry Unit) with MTU (Master Terminal Unit) if the separated by long distance. SCADA Repeater consists of an antenna , transmit amp , mini control and telemetry radio 433 MHz .

          RTU is set at a frequency of 433 MHz , while the MTU on a frequency of 440 MHz . The data transmitted from the RTU to MTU in the form of electrical parameters .

          The results obtained for the antenna has a VSWR of 1.23 and 1.32 frequency 433 MHz to 440 MHz , stable reinforcement 3 Watt amp transmit , Rx level repeater -56.38 dB , SOM (System Operating Margin) 60.62 dBm , and the system can communicate as far as 3.9 km.
