Description

The present invention relates to the field of home automation 5, and more particularly to an automation for a roller shutter or a blind or a group or a group of blinds and / or blinds. shutters and / or blinds. The use of motorized shutters or motorized blinds is now widespread in homes or business premises. In motorized systems, each shutter and / or blind is driven up or down by a motor coupled to the axis of the shutter and / or blind. The oldest system for controlling the shutter and / or blind actuators is the wired system. There are two types: a first type in which the various shutters and / or blinds are controllable only individually, generally by a control means near the shutter and / or blind and a second type, said centralized , made with relays, in which the various roller shutters and / or blinds are centrally controllable. These first systems have the disadvantage that they are not able to detect the opening or closing of shutters and / or blinds. The control of a group of shutters and / or blinds is necessarily performed by programmable clocks or external electronic timers. It is therefore not possible with such systems to control the raising or lowering of a group of roller shutters and / or blinds, simply by pressing with a short pulse on push-type switches.

The most recent system for controlling shutter and / or blind actuators is the wireless system.

Each motor coupled to a rolling shutter axis and / or blind has a radio transmission / reception module, and receives instructions from a control panel by wireless radio communication. This second type of system is easily adaptable in existing premises. However, each engine associated with it a radio transmission / reception module, this type of system multiplies the number of receivers in standby. In addition, these systems are often less reliable because of the strong integration of electronics therein, and they have a shorter life than wired systems. Also, they generate electromagnetic waves in the building, which can be a source of inconvenience for its occupants. In addition, they require programming. The present invention aims to overcome the disadvantages of existing systems, and relates to an automation for roller shutters and / or blinds with no idle power consumption, simple to use, allowing control of a roller shutter / blind or a group of shutters / blinds. The present invention uses relay technology, the various links being wired. The driving of a group of shutters and / or blinds is done simply by either pressing a "mounted" push-button switch or a "descent" push-button switch, or by the pulsed dry contacts of other devices such as building automation plant.

There can obviously be several "up" and "down" switches of the same group of shutters and / or blinds. The invention is designed to last a long time, is troubleshoot by an electrician, does not generate electromagnetic waves, does not need programming and consumes no energy in idle mode. Finally, the automation of the invention is adaptable to all types of devices, which allows the user not to be bound to a manufacturer of particular devices. In the present invention, the term "relay" will be used to designate electromechanical relays. The invention therefore relates to an automation for controlling the raising or lowering of one or more rolling shutters and / or blinds, characterized in that it comprises: - a power supply; a plurality of mechanical motors with a mechanical end of travel, each driving up or down a roller shutter or blind or a group of roller shutters and / or blinds; a central switch for raising control of all the shutters and / or blinds; a central switch for descent control of all the shutters and / or blinds; - a self-hold relay, activated by the central climb control switch, and a self-hold descent relay, activated by the central descent control switch, a first contact output of the self-sustaining relay being connected in series to the input of a second contact of the self-sustaining relay and an output of a first contact of the self-sustaining relay being connected in series at the input of a second contact of the self-hold relay; a rise relay activating the rising terminals of the motors and connected to an output of the second contact of the self-sustaining relay corresponding to the deactivated state of the self-sustaining descent relay; a descent relay activating the motor descent terminals and connected to an output of the second contact of the self-holding relay corresponding to the deactivated state of the self-hold relay, so that activation of the self-hold relay activates the rise control relay and activation of the self-hold relay activates the descent control relay. The central control switch, up or down, can be a push button or a dry contact from an upstream device. The system of the invention, relay base, is robust, the relays are reliable components, easy to troubleshoot because in case of failure, it suffices simply to change the faulty relay. In addition, it generates no electromagnetic wave and especially has no power consumption at rest. This architecture also ensures that a central climb control and a central descent control are not simultaneously sent to the motors. According to a first particular characteristic of the invention, the automation may comprise current detection means, said current detection means controlling the self-hold up and self-hold descent relays so that when the central climb control switch or the central descent control switch has been activated, the corresponding self-holding relay remains on as long as there is a motor that has not reached its end position. Thus, a single pulse on the central switch 5 for raising or lowering is sufficient to raise or lower all shutters and / or blinds connected to the automation. According to a first embodiment of the invention, said current detection means may consist of a first voltage detection circuit controlling the trigger of a first triac connected between the power supply and the self-sustaining relay. and a second voltage sensing circuit controlling the trigger of a second triac connected between the power supply and the self-sustaining descent relay. According to another embodiment of the invention, said current detection means may consist of a single voltage detection circuit controlling a triac connected between the power supply 20 and the input of a third contact of the relay of self-hold-up, the self-hold relay being connected to the output of the third contact corresponding to the active state of the self-hold relay and the self-hold relay being 25 connected to the output of the third contact corresponding to the inactive state of the self-hold relay. Each motor may furthermore comprise an individual pair of up and down push-buttons enabling, for a given motor, to only raise or lower the shutter or blind associated with this motor. An individual pair of up and down pushbuttons can also control parallel motors.

Each roller shutter or awning can thus be controlled centrally or individually. According to a particular characteristic of the invention, in each individual pair of push buttons, the push-up button and the push-down button can be dry contacts at an input and two outputs, the input of the push-up button being connected. to the power supply, a first output of the up-push button corresponding to its activated position being connected to the rising terminal of the corresponding motor, the second output of the rising push-button being connected to the input of the down-push button, a first output of the descent push button corresponding to its activated position being connected to the descent terminal of the corresponding motor, the second output of the descent push button being unconnected. With this architecture, local climb control and local descent control can not be simultaneously sent to a motor. According to a particular characteristic of the invention, an input of a fourth contact of the self-hold relay can be connected to the power supply, the output of the fourth contact corresponding to the active state of the self-sustaining relay. holding up being unconnected, the output of the fourth contact corresponding to the inactive state of the self-holding relay being connected to the input of a third contact of the self-sustaining relay, the output the third contact corresponding to the active state of the self-sustaining descent relay being unconnected, the output of the third contact corresponding to the inactive state of the self-sustaining relay supplying the individual pairs of push buttons climb and descent. This particular architecture thus gives priority to the central controls with respect to the individual commands of the motors, the activation of one of the two self-sustaining relays cutting power to the individual push-button pairs for all the motors. To better illustrate the object of the present invention, two particular embodiments will be described below, with reference to the appended drawing. In this drawing: - Figure 1 is a diagram of an automation according to a first embodiment of the invention; and Figure 2 is a diagram of an automation according to a second embodiment of the invention. With reference to FIG. 1, it can be seen that there is shown a diagram of an automatism according to a first embodiment of the invention. In the figures, N, P and T respectively represent neutral, phase and earth. In the present description, as indicated above, the term relay will be used to designate electromechanical relays. The automation according to the first embodiment of the invention comprises a power supply A, supplying all the elements of the automation. The automation of the present invention, shown in Figure 1, can control several motors M roller shutters and / or blinds, for their rise or descent, the motor control can be centralized via a button ICM central push-button and a central ICD descent push-button, causing all the shutters and / or blinds of the automation to be raised or lowered, or located on a particular motor via a pair of push-up buttons IM and descent ID, specific to a particular motor M, and causing the raising or lowering of the roller shutter or blind depending on this engine. Each motor M is a 220V three-wire motor (up, down, neutral) at the end of mechanical travel and has a ground terminal T, a neutral terminal N, a rising terminal H and a lowering terminal B.

The automation of the invention has a relay-based architecture, and includes an RM rise control relay, a RD descent control relay, an AM raise self-hold relay, and an auto-relay relay. maintaining descent AD, arranged as will be described below.

The relays AM, AD, RM and RD are four-contact relays, each contact having an input, a first output corresponding to the active / activated state of the relay, and a second output corresponding to the inactive / inactivated state of the relay .

In what follows, "first output" of a relay contact will mean the output of that contact that is activated when the relay is activated, "second output" of a relay contact will mean the contact output that is activated when the relay is not activated.

The same terminology will be used for pushbuttons at one input and two outputs. To facilitate the legibility of the diagram, upstream of the motors M terminal blocks VR1, VR2, VR3 and VR4, a single motor M being shown connected to the terminal block VR1. It is however understood that in use, in the diagram of Figure 1, motors are also connected to the VR2 and VR3 terminal blocks, or VR4, similar to the motor M connected to the terminal block VR1. We will therefore describe only the terminal block VR1, the description of the terminals VR2 and VR3 being identical. The terminal block VR1 comprises five terminals: a first terminal connected to the earth T of the motor M, a second terminal connected to the neutral terminal N of the motor M, a third terminal connected to the input of the push button IM, a fourth terminal connected to the rising terminal H of the motor M and a fifth terminal connected to the lowering terminal B of the motor M.

As can be seen in FIG. 1, the fourth terminal of the terminal blocks VR1, VR2, VR3 and VR4 is connected to the first output of the contacts, respectively rmi, rm2, rm3 and rm4 of the rise control relay RM, while the fifth terminal of the terminal blocks VR1, VR2, VR3 and VR4 is connected to the first output of the contacts, respectively rdi, rd2, rd3 and rd4 of the descent control relay RD. The second output of each of the contacts rmi, rm2, rm3, rm4, rdi, rd2, rd3 and rd4 is unconnected.

Thus, when the rise control relay RM is activated, the rise terminals H of the motors M are supplied with current and the corresponding shutters or blinds rise, whereas when the descent control relay RD is activated, the terminals of descent B motors M are powered and the corresponding roller shutters or blinds go down. AM contact input contact AM contact is connected to the power supply phase A, the first output of the AM contact is not connected, the second output of the AM contact is connected to the input of the adi contact of the self-sustaining descent relay AD. The first output of the adi contact 5 is unconnected, the second output of the adi contact being connected to the third terminal of each of the terminal blocks VR1, VR2, VR3, VR4 when neither of the two self-hold relays AM or descent AD is enabled, for use of the motors with pushbuttons IM and ID, as will be described below. The inputs of contact AM2 of the AM self-sustaining relay and the contact AD2 of the AD self-sustaining relay are connected to the phase of the power supply A. The first output of relay contact am2 AM self-hold circuit is connected in series to the input of contact AD3 of self-sustaining trip relay AD and the first output of contact ad2 of self-sustaining trip relay AD is connected in series at the input of the am3 contact of the AM self-hold relay. The second output of the contact ad3 is connected to the rise control relay RM, the second output of the contact am3 being connected to the descent control relay RD. The second output of each of the contacts am2 and ad2 and the first output of each of the contacts ad3 and am3 are unconnected. The central ICM pushbutton IC is connected to the AM self-holding relay, the ICD central descent pushbutton is connected to the self-holding descent relay AD.

Thus, with this architecture, an activation of the central ICM push-button activates the AM self-hold relay, which activates the RM rise control relay and therefore makes all the roller shutters and / or blinds. Activation of the ICD central descent push button activates the self-sustaining descent relay AD, which activates the descent control relay RD and thus lowers all the shutters and / or blinds. We can see on the diagram, through the connection of the contacts am2, ad3, ad2, am3 that in case of a simultaneous activation of the central push buttons ICM and descent ICD, it is the first of the buttons supported who will send the climb or descent order. A current detection circuit in the system phase is constituted by the diode bridge D1, D2, D3 and D4, connected between the phase of the power supply A and the inputs of the contacts rml, rm2, rm3 and rm4 of the relay. RM rise control. The diode bridge detects a voltage on the phase of the automation as long as one of the motors M of the automation is moving upward. This voltage activates the opto-triacs OT1 and OT2 which control the trigger of a triac TRI1 connected between the phase of the automation and the self-sustaining relay AM rise. Thus, as long as one of the motors of the system has not arrived at the end of the stroke, the AM raise self-hold relay is activated and thus the RM rise control relay is activated. Once all the M motors are at the end of the stroke, no voltage is detected on the phase of the automation and the AM self-holding relay is deactivated, also disabling the RM rise control relay: no more current flows in the automation which therefore consumes no electrical power at rest.

A similar circuit, comprising a diode bridge D5, D6, D7 and D8 controlling opto-triacs OT3 and OT4 controlling the trigger of a triac TRI2 connected between the phase of the automation and the self-sustaining descent relay AD achieves the same result in a centralized descent control, ie a power supply of the system as long as one of the motors does not reach the end of the race, and a power failure of the system when all the engines are at the end of the descent race. As indicated above, it is also possible to individually control each motor M by means of pushbuttons IM and ID. The input of the pushbutton IM is connected to the third terminal of the terminal block VR1, the first output of the pushbutton IM is connected to the rising terminal H of the motor M and the second terminal of the pushbutton IM is connected to the input push button ID. The first output of the push button ID is connected to the descent terminal B of the motor M, while its second terminal is unconnected. Thus, putting the IM and ID push buttons in series makes it possible not to send on the motor M at the same time an order of rise and a command of descent. In this diagram, the climb has priority over the descent, but it could obviously be envisaged that the descent has priority over the climb by reversing ID and IM, without departing from the scope of the present invention. It can also be seen that, via the contacts ami and adi, the centralized control has priority over the individual control of the motors. In fact, as soon as one of the self-sustaining AM or AD lowering relays is activated, the third terminal of the terminal blocks is no longer powered, and it is therefore no longer possible to act on the controls. The single push button on the ICM and ICD central pushbuttons makes it possible to raise or lower all the shutters and / or blinds, as a result of the AM and AD self-holding relays. . On the other hand, for push buttons IM and ID, it is necessary to stay pressed until the desired position or until the end of the corresponding motor stroke. The automation according to the present invention also offers the possibility of providing a potential free contact. This will allow, if necessary, to control another control system of shutters and / or wire blinds of the same type. In this case, the normally open contacts rm4 of the rise control relay and rd4 of the descent control relay will be connected to the centralized control connectors CCD and CCD of another control system. To do this, in connection with the diagram it will be necessary to cut the links S1, S2, S3, S4 and to make the two-wire connections between S1.1 S4.2 and S3.1 S2.2. Figure 2 shows another embodiment of the automation according to the present invention, in which a single current sensing circuit is used, thereby saving components. The diagram of FIG. 2 being identical to the diagram of FIG. 1 except for the current detection part, the elements common to the two diagrams will not be described in more detail, and only the different part will be described. The components that differ between the two Figures will have the same reference number followed by a "" character, the other references remaining identical to those of Figure 1.

In this second embodiment, the triac anode TRI1 'is connected to the input of a contact am4 of the AM self-holding relay, the first output of the contact am4 being connected to the relay of self AM rise hold and the second output of the ad4 contact being connected to the self-hold down relay AD. The operation of the diagram of Figure 2 being otherwise identical in all respects to the diagram of Figure 1, it will not be repeated here. The relays used to make the automation 15 will be standard type and media. Relays are elements of great reliability, nevertheless if one of them failed, the present invention simply allows the replacement of the defective relay. The automation is serviceable and therefore sustainable in the proper sense of the term, an advantage over other non-repairable devices so disposable. The fact that the system can be serviced by a person having a culture of electrician and that the centralized controls are controllable by an external device, provides an additional advantage: the user is not related to the manufacturer of the device and retains full freedom to upgrade his building automation system with the equipment of his choice. Finally, the present invention controlling roller shutters and / or blinds equipped with well-chosen wired motors is a less expensive solution than a "wireless" control solution.

Although the embodiments have been described with four-contact relays, relays having a different number of contacts could also be used, without departing from the scope of the present invention. Advantageously, the current detection circuit is made with oversized components in order to increase the reliability of the automation of the invention.
