Description

CONTROL UNIT
The present invention relates to a control unit for the transmission of control data especially in the control/ monitoring system of a building, said control unit being provided with a rotatable control knob for varying the control data and with a scale around the control knob.
The object of the invention is to achieve a multi-purpose control unit permitting of flexible modification and allow¬ ing the user, in the first place an inhabitant of a set of rooms in a building with an electronic system controlling the entire electrical equipment, to input instructions for the control of lighting, heating or similar things. Such a system is an essential .part of a so-called intelligent building. The control unit replaces the lighting switches and regulators and other possible controllers.
Especially in systems designed for a very large number of users, the user interface has to be clear and simple enough to allow the user to know what effect will be achieved by a familiar control action such as turning a knob, even if the user has never seen the particular user interface before. The system must be capable of giving the user clear infor¬ mation on the current value and the new adjusted value of the quantity being adjusted. The user interface should invite the inhabitant to make use of the interface instead of being an obstacle to its use. The functions of the user interface should permit of variation by programmatic means so as to make it fit for the adjustment of any quantity relevant to the building in question. In addition, its price has to be sufficiently low.
The control unit of the invention is characterized in that the unit has a number of push-buttons for the selection of the quantity to be controlled by the control knob and/or for the transmission of other information to the system, and that the control unit feeds the control data varied by the control knob into the system and presents information representing the system's measurement quantities, setpoints or equivalent on a semiconductor lamp or liquid crystal scale controlled by the system.
The preferred embodiments of the invention are presented in the other claims.
E.g. in the case of illumination control, an intelligent control system makes it possible to use a completely new principle: Especially in the most demanding space of a dwelling, the living room, which may have a large number of lighting fixtures, it is more pleasant for the user to se¬ lect a preprogrammed condition of illumination at the press of a button and to alter the general level of illumination by turning a single control knob rather than regulating the various lamps separately. It is thus possible to incorpor¬ ate various preprogrammed illumination conditions in the system to meet the varying illumination demands during activities like cleaning, house parties etc. The control unit is applicable both for the preprogramming of illumina¬ tion conditions and for,the selection of a condition.
The control unit of the invention was developed by consid¬ ering both the demands of the system and those of the users. The control unit serves as a room-specific local terminal, enabling several parallel units to be used to control the same quantities in the same spaces. Control units connected in parallel can also be programmed so as to allow them to control different quantities, e.g. one unit to control illumination and another to control the tempera¬ ture. The control unit also allows the use of large-scale control functions affecting even other spaces included in the system. In the following, the invention is described in detail by the aid of an example by referring to the drawings attached, in which:
Fig. 1 presents the control unit of _he invention.
Fig. 2 illustrates the structure of the control unit.
Fig. 3. presents a cross-section of the control unit, sectioned along the plane of a pair of push-buttons.
Fig. 4 illustrates the structure of the push-buttons.
Fig. 1 presents a control unit designed to be mounted on a wall e.g. by the door of a room. It comprises a control knob 2 together with a scale 3, placed on a cover panel 1, and a set of push-buttons consisting of seven successive pairs of buttons 4, 5, the buttons in each pair being placed side by side. The control quantity is adjusted by means of the knob 2, which actuates an optical or galvanic potentiometer and is surrounded by a scale 3 consisting of LEDs. It indicates the current value by means of a column display encircling the knob, and the setpoint by means of a separate lamp of a different colour. The type of display and the colours can be selected by programmatic means. For example, it is preferable to make a distinction between the values for heating and illumination by the use of different types of display and different colours. Moreover, the control unit is provided with rows 6, 7 of LED columns of the same height as the push-buttons, placed on the inner side of the buttons and emitting e.g. red light against the button being pressed and green light against the other buttons. The control unit also comprises an end piece 8 and a two-digit numeric display 9 placed above the scale 3 and displaying the midpoint of the scale as a numeric value. It can also be used for continuous display of the setpoint or the current value determined by the knob position. Fig. 2, illustrating the structure of the system, shows the central unit 10 of the system, room-specific nodes 11 con¬ nected to it by conductors 11 , and control units 14 con¬ nected to the nodes by conductors 13. The rotary motion of the knob is converted optically by the control electronics into electric pulses, which are transmitted to the room- specific node. The control unit 10 communicates with each node 12 via a two-way optical or galvanic digital connec¬ tion. The control unit is connected to the connecting con¬ ductor with a detachable connector (not shown) . The con¬ necting conductor carries a low voltage, allowing the user to replace the control unit himself e.g. in the case of in¬ creased control demands when more push-buttons are needed.
The quantity to be controlled is selected by means of the push-buttons. The function of all the push-buttons can be changed by programmatic means. The user himself can change the text or symbol representing the function of the button by replacing the push-button cover plate.
The mechanical structure of the control unit is so imple¬ mented that the same mould can be used to produce control units with different numbers of pairs of push-buttons. The number of button pairs needed varies according to the need in each place of application. The essential point is that it is not necessary to have a separate mould for each size of control unit. This is implemented by making the elec¬ tronic circuit card 16 and the bottom 15 of the control unit (Fig. 3) such that they can be truncated to fit units having less than the full number (e.g. eight) of buttons. The end piece 8 locks the buttons in place. The circuit card is provided with sensors 17, 18. When a button is pressed, a pin 19, 20 on its underside touches the sensor. The outer edge of each push-button is provided with a claw 21, 22 which is so fitted relative to the edge 23, 24 of the bottom 15 that the sensor will operate. Along the sides
i of the middle part 25 of the control unit there are tracks 26, 27 acting as axles for the push-buttons. The buttons are mounted on the axles by inserting them from one end onto the tracks. After all the push-buttons have been mounted, they are locked in place by means of an end plate 8. As shown in Fig. 4, the push-buttons 4, 5 are provided with grooves 28, 29 fitting the axles. The push-buttons may also be so designed that they can be mounted in place by inserting from the top of the unit.
The width of the control unit corresponds to that of currently used wall-mounting electric switches. Its length varies according to the number of push-buttons used. Since the control unit can be produced in a completely surface- mounted design, the length variation is no problem.
To simplify the wiring, the control units are connected to the system in parallel. This means that it is possible to connect several control units recognizing their own addresses to a single multipole conductor leading to the room-specific node.
By using modern surface mounting techniques and custom- designed ASIC circuits, the electronics of the control unit can be made compact and cheap.
It is obvious to a person skilled in the art that different embodiments of the invention are not restricted to the ex¬ ample described above, but that they may instead be varied within the scope of the following claims.
