reference project — Royal & Imperial Belvedere, hotel automation

Belvedere · Room Management SystemEvery room, on one reception screen

At the Belvedere, the room knows by itself when a guest is inside. It switches on what is needed, switches off what wastes energy, and tells reception and housekeeping straight away.

the project

Room control without key cards

For HIGHDRO, KP Automation designed and implemented the automation of the Room Management System, a solution for hotels that runs at the Royal & Imperial Belvedere. Every room has its own Siemens LOGO! 8 controller, which decides on its own based on the door, the presence sensor and the balcony door. A Siemens S7-1200 collects the data from all rooms and shows it on one reception screen, floor by floor.

The system works with the door locks the hotel already has. No key cards and no lock changes are needed, and it is designed around the needs of each hotel.

0entry cards: it works with the locks you already have

presence without a card

How the room knows a guest is inside

1 · door

The door closes

The door contact shows that someone came in or went out.

2 · sensor

Movement is detected

The presence sensor confirms whether someone is inside.

3 · decision

The room adapts

With a guest: power and air conditioning. Without a guest: everything switches off.

who benefits

One solution, four teams who use it

Owner

No air conditioning running in an empty room or with the balcony door open.
No key cards, no lock changes.

Technical manager

Siemens industrial hardware, not a “smart gadget”.
Every room works on its own, even without the network.

Reception

All rooms on one screen, floor by floor.
Air conditioning ready before the guest walks in.

Housekeeping

Knows which room asks for cleaning and which for quiet.
Enters when the guest is out.

architecture

Simple by design, so it stays reliable

Every room has its own LOGO! controller and decides on its own. The reception screen monitors and sends commands. If the computer or the network stops, the rooms keep working normally.
