Description

Field

The exemplary and non-limiting embodiments of this invention relate generally to control of a screening device and more particularly to interruption of the controller.

Background

Buildings, windows and doors may use screening means like awnings, roller shutters, shades, blinds and other screening devices etc. Such screening devices may be motor driven and controlled based on sensor values. For example DE202006009694U shows a screening controller with a selector switch (531) for selecting the operation mode of the controller (fig. 2). WO 2006/026682 relates to operating window coverings, where a controller of generates control signals based on input, and a sleep mode is provided. A further screening device is disclosed in JP 2007 277833 A .

Summary

Controllers which control the operation of a screening device based on climate sensors are unpredictable and consequently have not been so widely adopted. A user can never predict when the screening will be operated and this is a drawback with regard to comfort, privacy and security etc. It would be desirable to provide screening device control which enhances the user comfort, privacy and security and further provides easy and sensible interruption of the operation of the controller.
Further is would be desirable to provide a screening device control which automatically resumes the operation so a user does not forget to enable the operation. A screening device may further be controlled to reduce the heat gain or heat loss (e.g. energy savings) and if a user forgets to enable the control of the screening device the result is energy loss and reduction of the thermal comfort. Likewise the security may be reduced if a user forgets to enable the screening control.
The user comfort may be disturbed by the noise generated by the motor driven screening device. It would be desirable to provide a user friendly and intuitive way to provide enhanced user comfort.

Detailed description

The disclosed embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which certain examples are shown. Like numbers refer to like elements throughout.
Fig. 1 illustrates a building with screening devices 1 and windows 2. Screening devices may for example be an awning 1a, roller shutter 1b or venetian blind 3c. Such screening devices may for example be controlled by integrated, wired or wireless controllers 3,4,5. Sensors 6 may measure the climate 7 both inside and/or outside in order to control the position of the screening devices in a logical manner. For example the climate sensors may be a temperature sensor, solar sensor, solar angle/direction sensor, wind sensor, rain sensor, light level sensor, air quality sensor etc. Based on the sensor(s) the controller may operate the screening to conserve the temperature e.g. reduce heat gain and heat loss. Hereby user comfort is increased and energy savings are provided. Based on the sensor(s) the controller may operate the screening to provide privacy by closing the screening when it is dark/evening.
Advantageously the controller is configured to provide energy savings and improve the thermal comfort. The energy savings are enhanced by a plurality of aspects, illustrated by the following examples: In one example the controller is preconfigured to interrupt the screening operation during night to provide silence and further configured to resume the screening operation the next day. Hereby the user does not experience disturbance and allows the controller operate, whereas a disturbing controller has the risk of being disabled by the user.
In one example the controller resumes normal operation either next day or after a countdown time. When the controller is manually interrupted the controller may resume normal operation, so there is no risk that the user forgets to enable the controller and waste of energy/thermal comfort. In one example the controller receives the position of the screening (for example by polling) and operates the screening if the position is not optimal. Hereby the energy savings and thermal comfort is improved, because a screening may be manually opened or closed by a user and the user may forget to return the screening to the optimal position. Likewise the screening may be manually operated during interruption and when the controller resumes the controller receives the position of the screenings to verify that the screenings are positioned correct and the controller operates the screenings if position is not correct.
The controller comprises a processor including one or more timers and possibly a calendar program. To control the position of the screening device the controller has a motor driver or communication facilities to a motor driver. Possibly the controller receives feedback of the position of the screening device(s). The controller receives climate sensor data by wire or wirelessly. Based on the climate data the controller may control the position of the screening to provide comfort, privacy and security. The controller may be one unit but also more units, like a wireless controller 4 (remote) and integrated device controller 5. A central home automation controller may also cooperate with plural terminals or remotes.
Fig. 2 illustrates an example of a controller 10 with a display 11 and input keys 12. As mentioned a controller may be wireless like for example a screening remote control. The display 11 provides navigation and allows the user to select one or more screening devices 13. The screening devices may also be arranged in groups or rooms, like shown in fig 2. "Bedroom 1" is selected and the display shows the screening devices from "Bedroom 1 ". The controller provides selection of a screening device 13 and allows setting a position 14 e.g. opening or closing the screening.
The screening controller has user input means. The controller input means may for example be a remote, a keypad, dial, a graphical user interface and the input may be provided through sensors configured to detect the user's gestures etc.
Fig. 3 illustrates one example of interruption scheme definition. In one example the period 15 like weekdays or weekends 15 may be selected. Then the start time 16 of the interruption and end time 17 of the interruption is configured. Other examples are possible, like each week day (Monday to Sunday) where interruption may individually be defined. The interrupt scheme may be continuous and employ start time 16 of the interruption and end time 17 of the interruption.
The interruption scheme may be predefined based on one or more criteria. For example the criterion "room name" may be used to provide different interruption schemes, because a bedroom and a garage have different needs, so comfort is more important for bedroom while security and energy savings in garage. So the interruption schemes may be predefined based on the room name. The room type/names may for example be kitchen, bathroom, toilet, bedroom, office, hall, living room, dining room, TV room, garage etc.
The screening device name may similarly be a criterion. Screening devices generate different amount of noise. For example a roller shutter makes more noise than an awning. For example and screening device mounted outside like awning makes less noise than a screening device mounted inside like venetian blind. So the predefined interruption scheme may take into account the name/type of screening device. (The noise criterion may also be stored in a device by the manufacturer, so a more precise interruption scheme may be offered.)
Criteria like the room name criterion and/or screening device name/type criterion may be used to suggest more relevant interruption schemes to the user. Alternatively the user may manually define a noise criterion for a room, a screening device or a group of screening devices and based on the user defined noise criterion the interruption scheme may be predefined.
Fig. 4 illustrates another example of defining the interruption scheme. An input 18 (Disable) in the main screen 11d allows quick and user friendly interruption. The input 18 may be a key pressed in a sequence or long pressed to gradually increase the interrupt scheme 19 (1 hour, 2hours, 6hours, 12hours, permanent). Hereby a single soft key 18 enables the user to disable, enable and interrupt the controller for defined time in a very easy and intuitive manner.
In one embodiment the controller has at least a first scheme and a second scheme, where the first scheme is explained in connection with fig 3 and the second scheme is explained with in connection with figure 4. Hereby the controller is flexible by allowing a user to set up the first continuous scheme (for example during night) and also providing the option to activate the second instant scheme when sudden interruption is desired.
The scheme may be continuous which is understood as reoccurring every period such as every day. The period may also be day, week, month, season etc. or based on a calendar. The continuous interrupt scheme may employ start time 16 of the interruption and end time 17 of the interruption.
