METHOD AND SYSTEM FOR BUILDING AUTOMATION

FIELD OF THE INVENTION

The present invention relates to a method for building automation and more particularly to a method according to preamble of claim 1. The present invention also relates to a system for building automation and more particularly to a system according to preamble of claim 12.

BACKGROUND OF THE INVENTION

The building automation systems are conventionally used in buildings having two or more building spaces. The building space may be an apartment, an office, a room, or another space in the building. It should be noted that the building may be separate building or a separate part of the building such as a staircase of the building with two or more apartments. The building has a layout which is defined by locations, or relative locations, of the building spaces in the building.

Thus, a physical layout of the building defines physical locations of the two or more — building spaces in the building. The building automation system usually comprises a building space automation unit provided to the building space. Accordingly, at least one building space automation unit is provided to one building space. The building space may further be provided with one or more building space measurement devices. The building space measurement devices are connected to — the building space automation unit. Therefore, the building space automation unit is configured to collect all the measurement data from the building space. The building is further provided with a building automation unit. The building space automation units of the building are connected to the building automation unit. The

D building automation unit is configured to collect measurement data from the

S 25 — building space automation units and possible process the collected measurement

A data for purposes of the whole building. The building automation unit may be for

N example a programmable logic controller. For the system, it is important that a r correct building space automation unit is associated to the corresponding building & space in the building automation unit.

I 30 During installing the automation system each building space > automation unit must be manually connected to building automation unit. This is = carried out such that first the building automation unit is installed to the building.

N Then, a first technician installs the building space automation unit to a first building space and connects the first building space automation unit to the building automation unit in the building space. Then, the first technician switches on the first building space automation unit. At the same time, a second technical is at the building automation unit. When the first technician switches the first building automation unit on, the first technician informs the second technician that the first building space automation unit about to be switched on in the first building space.

The second technician observes the building automation unit, and when the first building automation unit is switched on the second technician notices the first building space automation unit in the building automation unit and connects the first building space automation unit to the first building space in the building automation unit. Then the same procedure is carried to a second and subsequent — building spaces of the building.

One of the problems associated with the prior art is that installing the building automation system is carried out manually and installing each building space automation unit requires two technicians and simultaneous communication with the two technicians. This is very time consuming and subjects the installation — toerrors. Furthermore, the conventional installation of the automation system also requires manual modifications when the system is updated or the building space automation unit is changed or new building space automation unit is installed to a building space.
