Di lapangan saya membutuhkan alat dummy scada yang mana bisa dikontrol atau monitoring via android ASUS Z5 (promosi... wkwkkwk).
Kali ini akan saya jabarkan oprek arduino yang mau saya gunakan di lapangan. Saya membuat alat yang bisa digunakan :
1. untuk dummy SCADA, seperti monitoring kontrol dari master station, injek status ke master station.
2. untuk monitoring tegangan baterai rectifier saat pengujian ketahanan baterai.
3. untuk supply tegangan 110VDC
Alat saya ini mempunyai fitur :
1. wifi (kenapa memilih ini??? karena jangkauannya bisa jauh. berbeda dengan bluetooth)
2. portable (bisa dibawa kemana-mana), kecuali supply tegangan 110 harus dicolokin ke 220VAC
3. ringan sekitar 2 ton kurang...... alias cuma + 2kg.
4. indikator tegangan baterai
Material yang perlu disediakan, antara lain:
1. Arduino Mega
2. Ethernet Shield
3. Wifi Router TPlink
4. Switching 12V 2A
5. Baterai 12V 2A
6. Modul DI AI DO
7. Step down 12V to 5V
8. box 300 x 300
Langkah-langkah:
1. pasang arduino, ethernet shield, modul DI DO AI, switching, wifi router, step down
2. upload sket to arduino

}
3. Masukkan kedalam box
4. Wiring semua komponen material
5. Jadilah alat uji portable
alat ini kami uji dengan relay Micom P127 dan ION 6200
Pengujian baterai ( maaf tadi saat pengujian lupa di screenshoot, insyaalloh nanti jika ada waktu luang akan saya upload lagi)
tampilan HMI alat dummy
alat ini bisa diaplikasikan, antara lain:
1. Home automation
2. kontrol pintu gerbang via HP.
3. start engine mobil dari jarak jauh.
4. dll...................masih banyakkkkkkkk
