Description
BUILDING AUTOMATION SYSTEM AND METHOD THEREFOR
TECHNICAL FIELD
The present disclosure relates to devices and methods of a Building
Automation System (BAS) in a building. BACKGROUND
In a BAS of a building it is necessary to configure wired and/or wireless devices manually based on their locations so that the Building Management System (BMS) can pair/associate the device with the room it is in or with other devices in the same or different location depending on the application requirement. For instance, the BMS needs to know which room a heating or lighting device relates to. Also, the device is assigned a name/address within the BAS to enable communication there with. Thus, a lot of time is needed to set up all devices in a BAS, which is usually done locally with a point-to-point connection to the device, or by using DIP switches, or by using external configuration plugs. There is thus a general need to ease the installation and commissioning of devices in a BAS.
SUMMARY

According to an aspect of the present invention, there is provided a method performed in a Building Automation System (BAS) of a building. The BAS comprises a Building Management System (BMS), a plurality of
communication devices, and a plurality of positioning devices. The method comprises a first communication device of the plurality of communication devices obtaining information about its position in the building based on measurements on wireless transmissions from at least one positioning device of the plurality of positioning devices, said at least one positioning device having a known position in the building.

communication device. The method also comprises the BMS determining the position in the building of the first communication device based on the received information. The method also comprises the BMS assigning at least one parameter to the first communication device based on the determined position. The method also comprises the BMS sending instructions to the first communication device, instructing the first communication device to be configured with the assigned at least one parameter.

BRIEF DESCRIPTION OF THE DRAWINGS
Embodiments will be described, by way of example, with reference to the accompanying drawings, in which:
Fig l is a schematic block diagram of an embodiment of a BAS in accordance with the present invention.
Fig 2 is a schematic flow chart of an embodiment of a method of the present invention. DETAILED DESCRIPTION
Embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which certain embodiments are shown.
However, other embodiments in many different forms are possible within the scope of the present disclosure. Rather, the following embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like numbers refer to like elements throughout the description.
Figure 1 illustrates an embodiment of a BAS 1 in accordance with the present invention. The BAS 1 comprises a plurality of communication devices 4 as well as a plurality of positioning devices 3 (which could in some
embodiments be regarded as anchors). On a higher level in the BAS 1, there is a BMS 2 for acting as a control unit of the BAS 1. Several different types of communication devices 4 are shown as examples in the figure, denoted 4a-f. Communication devices 4a, 4b and 4c are wired and configured for wired communication in the BAS, while the communication devices 4d, 4e and 4f are wireless and configured for wireless communication within the BAS. The wired communication devices 4a-c are connected to the higher level part of the BAS via a system access point 5. The wireless communication devices 4d-f are typically connected to the higher level part of the BAS via a radio access
point, e.g. comprised in the system access point 5. The positioning devices 3 may be connected to a localization server 9 which may e.g. hold information about the positions of the respective positioning devices 3. In addition to the BMS 2 and the Localization server, the higher level part of the BAS 1 in the embodiment of figure 1, as an example, includes a conference server 6, a security server 7 and an engineering terminal 8.
Figure 2 is a schematic flow chart of an embodiment of a method of the present invention. The method is performed in the BAS 1 of a building, comprising a BMS 2, a plurality of communication devices 4, and a plurality of positioning devices 3. The method is at least predominantly performed by the BMS 2. A first communication device 4 of the plurality of communication devices obtains Si information about its position in the building based on measurements on wireless transmissions from at least one positioning device 3 of the plurality of positioning devices. The at least one positioning device has a known position in the building, e.g. known and possibly broadcasted by the positioning node, and/or known elsewhere in the BAS e.g. by the BMS 2 and/or the localization server 9. The first communication device 4 then sends, and the BMS 2 receives S2, the obtained Si information about the position. The received S2 information may e.g. be the position (e.g. room number or coordinates etc.) or more raw information (e.g. reception strengths of the transmissions from the at least one positioning device 3) from which the BMS can calculate the position of the first communication device 4. Regardless, based on the received S2 information, the BMS 2 determines S3 the position in the building of the first communication device 4. Then, based on the determined S3 position, the BMS 2 assigns S4 at least one parameter (e.g. name/address) to the first communication device 4. The BMS 2 sends S5 instructions to the first communication device 4, instructing the first communication device to be configured with the assigned S4 at least one parameter. Thereby the first communication device is configured with the parameter as instructed by the BMS.
In some embodiments of the present invention, the wireless transmissions from the at least one positioning device 3 are radio transmissions. For
example, the transmissions may be in accordance with a Wireless Local Area Network (WLAN) communication standard, with an Ultra- Wideband (UWB) communication standard, or with a Bluetooth communication standard, e.g. iBeacon™. For positioning are radio frequency (RF) based Time of Flight, Time of Arrival and Time Difference of Arrival, methods which may be used to determine the distance between a communication device and a fixed anchor, e.g. a positioning device 3. By using multiple anchors 3 and distance measurements, the position of the communication device may be
triangulated in 2D or 3D depending on the number of anchors 3. Either of UWB and WLAN may be suitable RF carriers in this case. The time/distance measurement can also be complemented using angle information, thus adding the angle of the direction from the anchor 3 to the communication device 4. Another positioning method method is to measure the RF signal strength from a positioning device/anchor 3 and store a set of "finger prints" for an area where the communication device 4 is to be positioned. The communication device may then be positioned by measuring the signal strength of e.g. UWB or WLAN and comparing it with the stored finger prints.
Alternatively, in some other embodiments of the present invention, the wireless transmissions from the at least one positioning device 3 are ultrasonic transmissions. As an alternative to RF, audio ultrasonic
transmissions may be used for angle and distance measurements.
In some embodiments of the present invention, the first communication device 4 is a wireless communication device. Alternatively, the first communication device 4 is a wired communication device. However, the present invention may be particularly suitable for wireless devices 4, configures for wireless communication, since their positioning may be more flexible and thus less known.
In some embodiments of the present invention, the at least one positioning device 3 comprises a satellite navigation module, e.g. a Global Positioning System (GPS) module, or wherein the at least one positioning device 3 is
stationary and its position has been pre-set in the BAS 1. These are examples of how the position of a positioning device 3 may be known. As mentioned above, satellite positioning may not always be suitable for obtaining sufficiently accurate positioning (e.g. within 10 meters, 5 meters, 2 meters or 1 meters) indoors, why the positioning device(s) 3 may be anchors with preprogrammed positions e.g. into the respective positioning device 3 and/or the BMS 2 and/or the localization server 9.
In some embodiments of the present invention, the step of the first communication device 4 obtaining information about its position comprises obtaining the information based on measurements on wireless transmissions from at least two, preferably at least three, positioning devices 3 of the plurality of positioning devices, each of which having a known position in the building. The 2-dimensional or 3-dimensional position of the communication device may be more accurately determined with the help of two, three or more positioning devices/anchors 3 for triangulation.
In some embodiments of the present invention, the at least one parameter is an address to the first communication device 4, a name of the first
communication device 4, a cryptographic key for the first communication device 4, and/or an association of the first communication device 4 with a second communication device 4 of the plurality of communication devices. In some embodiments, where the at least one parameter comprises an association with a second communication device 4, the first communication device 4 is comprised in a lamp which has been determined to be positioned in a first room, and the second communication device 4 is comprised in a light switch positioned in said first room. Thus, the lamp may automatically be associated with a suitable switch for controlling the lamp.
In some embodiments of the present invention, the first communication device is comprised in any one of a lamp, a light switch, a wall power socket, a meter e.g. of electricity or water consumption, blinds or other window coverings, a heating regulator, a ventilation regulator, an air conditioning regulator, an alarming device, a sensor e.g. of temperature, humidity, light,
motion, fire, smoke or carbon dioxide, or a door entry system. These are just some examples of devices in which a communication device 4 may be comprised. Some other examples are also given in figure 1.
Examples Below follow a couple of brief examples of situations when embodiments of the present invention may be convenient.
Example 1 - Booking system to automatically control heat and ventilation
- A booking system informs the BMS 2 that a meeting will occur at time T for duration D in room R. - By means of the present invention, the BMS 2 knows which communication devices 4 are associated with room R and what type of devices they are comprised in, e.g. heating and ventilation.
- The BMS 2 orders the communication device 4 associated with heating in room R to turn on the heating prior to the meeting so that the temperature is comfortable at time T.
- At time T, the BMS 2 orders the communication device associated with ventilation in room R to activates the ventilation system in room R.
- At time T plus duration D the BMS 2 orders the respective communication devices 4 to deactivate the ventilation and turn off the heating in room R. Example 2 - Energy saving by automatically controlling wall sockets in an office building
- Each workplace in an office has intelligent wall socket W with integrated power switches.
- By means of the present invention, the BMS 2 knows which communication devices 4 are associated with each socket W in each room, and which
communication devices 4 are associated with the door entry system of the building or of said each room.
- When employee E enters the building or his room therein using the door entry system D the BMS 2 system automatically turns on the wall socket W at the employee's workplace.
- When employee E leaves the building using the door entry system D the BMS 2 system automatically turns off the wall socket W at the employee's workplace.
- The intelligent wall sockets in shared locations like meeting rooms may only be turned on by the BMS 2 during office hours, while at all other time they are turned off.
The present disclosure has mainly been described above with reference to a few embodiments. However, as is readily appreciated by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the present disclosure, as defined by the appended claims.
