Definitions
- the subject of the invention is a device for controlling an electromechanical actuator comprising a switch for making the electrical connections necessary for supplying the actuator, a processing unit controlling the switch and intended to be associated with a receiver for the remote control of the actuator and an auxiliary control means, with manual actuation, the actuation of which has the effect of modifying the state of the switch.
- the actuator is for example a motor driving a blind or a rolling shutter arranged in a box or a lighting means fixed to the ceiling. Such installations are well known.
- the actuators are generally controlled by at least one switch arranged in the living room or office concerned. These switches are placed within easy reach, either near the bay or near an entrance door. These switches are therefore connected by wiring to the control device mounted near the actuator and often constituting a unit with one actuator.
- the installation of this wiring represents a significant part of the total cost of one installation. This is the case, for example, of the installation described in US patent 6,181,089.
- the switch controls the switch via the processing unit (microprocessor).
- a similar installation is described in the utility model DE 9321 365.
- the main purpose of the invention is to reduce installation costs while retaining the possibility of working on the control device without using a remote control, whether or not the control device is fitted with a receiver for a remote control.
- Devices which combine direct manual control means and electrical means for driving an element or the parts which it drives, by means of a motor. Such combinations are found in particular in systems for controlling Venetian blinds.
- an autonomous device for motorizing the drive rod of a Venetian blind is described by means of a motor and a reduction gear, this device being provided with limit switch contacts.
- the motor is controlled by various signals, for example from light detectors or a remote control.
- remote control means for such actuators, using radio controls or various wireless commands, for example infrared or commands using one or more wires of the motor power cable. to transmit information, used by an electronic device as described in application EP 0 985 211.
- These control means relate to local control or general or at least group control of the actuators.
- US patent 5,397,869 is described a remote control system of a switch initially manual control, using a DC motor acting mechanically on the lever of the manual switch. This remote control replaces manual control.
- US Pat. No. 4,792,79808 provision is made for remote control of a cord switch, normally with manual control. The remote control allows you to act directly on the cord from a remote position. It is therefore a receptor causing a mechanical action and not a receiver doubled by a mechanical action.
- roller shutter actuators which can communicate with each other by a home automation link, for example using carrier currents. Each actuator can be controlled remotely by this common home automation link or locally by a radio or other link.
- the control device according to the invention is precisely characterized in that the auxiliary control means is a mechanical means of remote handling.
- mechanical means means without galvanic connection.
- the mechanical means with manual actuation can act either directly on the switch or on the processing unit.
- the mechanical means acts on the auxiliary contacts.
- the mechanical means is equipped with a magnet and acts magnetically.
- the mechanical means may consist of a rod or rod which can be actuated in translation and / or in rotation or at least one cord which can be actuated in traction.
- the invention also has the advantage of eliminating the unsightly effects resulting from the use of switches of different natures and of different shapes depending on whether they are lighting controls or other types of actuators such as motors for blinds or roller shutters.
- the invention also has the advantage of promoting simple and intuitive control ergonomics, in direct relation to the product to be ordered.
- the invention also makes it possible to keep the same mechanical or electromechanical device in the event that economic reasons force the user to postpone the investment of the receiver.
- the invention finally makes it possible to remedy the temporary drawbacks resulting from the non-functioning of a remote control (interference, need to replace the batteries of the transmitter, etc.).
- the installation of the receiver will not require any modification of the initial wiring within the same housing of the control device.
- FIG. 1 is the general diagram of the first embodiment.
- FIG. 2 shows a detail of the general diagram of Figure 1 applied to the control of an alternating current motor with two directions of rotation.
- FIG. 3 schematically represents an example of mode of action on the switch, according to the general diagram of FIG. 1.
- FIG. 4 represents the general diagram of a second embodiment.
- a control unit 1 is mounted near an actuator 2.
- This actuator can be a DC or AC motor or a lighting means.
- the control unit 1 contains a switch 3, a processing unit 4 controlling and controlling the state of the switch 3 and a receiver 5, the latter being able to be installed later.
- the control unit 1 is connected, on the one hand, to a current source, not shown, by an electrical connection 6 and, on the other hand, to the actuator by an electrical connection 7.
- the processing unit 4 is connected to the switch by a link 8 and feedback on the state of the link 7 is provided by an electrical link 9 to an input of the processing unit 4.
- the electrical connections have been represented by a single line, but it is clear that these connections will generally comprise several wires, the number of wires depending on the embodiment.
- the link 8 it can be electrical or magneto-mechanical depending on the type of switch used.
- the switch 3 can in fact be made up of mobile relay contacts, standard or specific or of static contacts associated with semiconductor switching devices.
- the link 8 will be precisely of the magneto-mechanical type.
- Figure 2 is a simple reminder, by way of example, of an application to an alternating current electric motor with two directions of rotation.
- the switch is here a conventional inverter with two outputs making it possible to supply one or the other of the two phases PI or P2 of the motor.
- the receiver 5 is a radio or infrared or ultrasonic receiver or also a carrier current receiver carried on the supply line. It can also receive a signal transmitted on a pilot wire not shown.
- the control device further comprises a vertical mechanical element 10 connected to the housing 1.
- This mechanical element 10 is intended to be actuated manually and it is easily accessible.
- the housing 1 therefore has a part projecting from the wall or the box in which is placed the actuator to be controlled, for its connection to the mechanical element 10.
- the mechanical element 10 may consist, for example, of a rod or rod which can be actuated in rotation and / or in translation.
- FIG. 3 An exemplary embodiment of the direct actuation of the switch 3 by the mechanical element 10 is shown in FIG. 3.
- the mechanical element 10 acts, by a connecting means 11, on an auxiliary contact 32 of the switch 3 in parallel to a main contact 31 activated by the processing unit 4.
- the connection means 11 can be purely mechanical, that is to say directly transmitting the movement of the mechanical element 10 to the auxiliary contact 32 or magnetomechanical, that is to say by the interaction of a magnet and ferromagnetic parts, arranged on the one hand on the mechanical element 10 and on the other hand on the movable part of the auxiliary contact 32.
- the action of the mechanical element 10 is preferably of the impulse type.
- the return 9 to the processing unit 4 is then used to know the action of the mechanical element 10 and to maintain this action.
- the processing unit 4 essentially comprises one or more relay coils and the return 9 ensures the self-supply of this coil, respectively of these coils, after a possible rectification and reduction of voltage drawn from the line , respectively lines 7.
- the processing unit 4 can also defer or cancel an action controlled by the receiver 5 if it finds that this action is in opposition to the manual control in progress by means of the mechanical element 10.
- the main contacts 31 are for example Uni-pole relay contacts, the excitation coils of which are contained in the processing unit 4.
- active semiconductor devices can be used, such as MOS transistors, thyristors, triacs or IGBTs. In such electronic embodiments, the link 8 is then purely wired.
- both the auxiliary contacts and the main contacts must have sufficient breaking capacity, taking into account the load ordered.
- the embodiment according to Figure 3 has a strong economic advantage: that of being able to install in two stages. Indeed, it will be noted that all the connections of the processing unit come to be made in parallel with the auxiliary contacts. It is therefore entirely possible to control the installation purely manually, with only the auxiliary contacts, as long as the processing unit and the receiver have not been installed.
- Manual control also allows control in degraded circumstances, for example following a failure of the receiver or because it would be necessary to change the used batteries in a remote control transmitter.
- suitable relays having an adequate configuration with a possibility of action on the movable armature, it is possible to dispense with the auxiliary contacts and act in an impulse manner directly on the main contacts. Maintaining the relay is then ensured by the link 9.
- the action on the movable frame of the relay can be exerted remotely by means of a magnet.
- FIG. 4 represents the second general embodiment consisting in acting, by means of the mechanical element 10 on the processing unit 4 and no longer on the switch 3.
- the action of the mechanical element 10 can be purely mechanical and direct, by acting on the state of one or more auxiliary contacts, with low breaking capacity, connected to a microcontroller or activating a relay coil within of the processing unit 4. This action can again be exerted partially remotely in a magneto-mechanical manner.
- the term contact must be taken in the broad sense and covers, for example, the use of a Hall effect probe or an optical device modifying the state of an input 12 of the processing unit 4.
- a specific stop command from a particular movement of the manual control element 10
- this can be processed either directly at the level of the switch 3, by insertion on line 6 of an auxiliary contact having a high breaking capacity, ie at the level of the processing unit 4, by action on an auxiliary contact allowing the change of logic state of an input .
- a stop order given locally using the mechanical element 10 will preferably have priority over an action initiated following an order received on the receiver 5.
- the vertical mechanical element 10 may consist of a rod manipulated in translation and / or in rotation, so as to act on a contact or on one or the other of a pair of contact.
- the contacts will preferably be arranged on the same vertical.
- the contacts will be arranged on the same horizontal plane. It is also possible that a downward movement of the rod actuates the specific stop contact. An articulation placed at the top of the rod will facilitate its maneuvering.
- a sequential operating mode of the manual control i.e. a first action causing a downward movement, a second action a stop, a third action an upward movement, a fourth action a stop, etc. is particularly suitable in the second general embodiment in which one acts by means of a single contact on a single input 12 of the processing unit.
- the rod 10 can be replaced by one or more vertical cords.
- the invention makes it possible to offer, in the same product and by greatly reducing the wiring constraints and the costs, the possibility of local and remote control.
- a major advantage of the invention is also to make it possible to postpone the act of investment relating to the remote control receiver: the so-called “auxiliary” contacts used in the first embodiment may temporarily suffice for a user decided to later install the remote control.
- the invention facilitates the implementation of remote control solutions by radio, when it is a question of selecting a receiver, in a pairing operation: one of the activated inputs of the processing unit by a change of state of the manual control can then advantageously be used to physically designate the receiver to learn a transmitter identification number.
