Arhitectura unui sistem de tip Home Automation

Prin noțiunea de Home Automation se înțelege implementarea unui sistem de automatizare și control centralizat al echipamentelor electronice de automatizare dintr-o locuință.

Automatizarea presupune două aspecte importante: monitorizarea și comanda automată. Monitorizarea se realizează prin intermediul unor echipamente electronice de tip senzori și traductoare ce pot măsura diverși parametrii specifici ambientului din locuință (temperatură, umiditate, luminozitate, calitate aer) sau diverși parametrii de funcționare a echipamentelor electronice (consum electric, stare pornit / oprit, căldură degajată, presiune sau debit apă etc.).

Partea de comandă presupune capacitatea sistemului de a reacționa și de a interacționa cu echipamentele electronice și electrocasnice (aparate de climatizare, sisteme de securitate, sisteme multimedia, sisteme de alimentare cu energie electrică) prin intermediul unor elemente de acționare.

Conexiunea dintre parametrii măsurați și comenzile automate se face prin intermediul unui sistem de comandă centralizat care poate acționa la comanda manuală a utilizatorului sau poate avea comportamente de comandă predefinite (dacă temperatura în cameră depășește 35 de grade Celsius pornește aerul condiționat).

Astfel, arhitectura unui sistem de tip Home Automation implică următoarele subsisteme:

  • Elemente de achiziție de tip senzori (sensors);
  • Elemente de acționare (actuators);
  • Sistem central de comandă (controller);

Legătura dintre elementele de achiziție, elementele de acționare și sistemul de comandă implică o rețea de comunicație. La momentul actual majoritatea sistemelor utilizează o rețea de comunicație fără fir datorită comodității de instalare și operare. Există mai multe produse comerciale ce oferă soluții complete de Home Automation dar acestea sunt incompatibile între ele (nu se poate folosi un senzor de tipul X cu un sistem de comandă de tipul Y) și au un cost destul de ridicat…
