Description

<Desc / Clms Page number 1>

 The invention relates to a method and a device for controlling a movable member, in particular a blind and / or rolling shutter, as well as a motor for a movable member, in particular intended for implementing said method.

 Although more particularly intended to be applied to blinds and / or roller shutters, the invention may relate more broadly to any movable member capable of being controlled by separate means for issuing a control order, in particular intended for send redundant messages to said mobile device.

 Currently, blinds are known which are fitted with detectors capable of causing them to fold back in the event of too strong wind. However, these detectors are located at the blind drum, in the vicinity of their motor, whereas it is their part least exposed to the wind.

 It was proposed by the applicant in French patent application NO FR-99 / 10.290 to place wind detectors at the level of the frame of the blinds. The relevance of the measurements carried out is thus improved.

 However, it then becomes necessary to introduce means of transmission allowing the result of the measurements to be sent to the mobile member and it has been analyzed by the depositor that the failures of these means of transmission could have dangerous consequences, if they remain undetected. Indeed, if they are not in working order, nothing indicates it to the user until the day when the blind is unfolded and when it undergoes a strong wind, without folding back. It is then too late to intervene.

 The object of the present invention is to propose a method and a device for controlling a movable member, in particular a blind and / or rolling shutter, which overcomes the aforementioned drawbacks and makes it possible to quickly reveal the failures of transmission means intended to relay. messages coming from means of detection of dangerous situations to the mobile organ.

 Another object of the present invention is to provide a movable member motor which can alternately operate in a mode

<Desc / Clms Page number 2>

 conventional and according to a mode corresponding, in particular, to the detection of the failures previously mentioned.

 Other objects and advantages of the invention will emerge during the description which follows, which is given for information only and which is not intended to limit it.

 The invention relates first of all to a method of controlling a movable member, in particular a blind and / or rolling shutter, in which commands to control its movements are transmitted to said movable member, on the one hand from at least at least one transmitter and on the other hand, from transmission means, intended to relay so-called safety messages to the mobile member, originating from means for detecting a dangerous situation, and in which said transmission means are requested during the use of said transmitter (s) and the operation of said transmission means thus activated is made detectable.

 The invention also relates to a device for controlling a mobile member, in particular a blind and / or rolling shutter, comprising on the one hand one or more transmitters and on the other hand transmission means intended to relay to the mobile device, so-called security messages from means for detecting a dangerous situation, the said transmitter (s) and the said transmission means being capable of transmitting to the mobile device control orders for its movements, the said device further comprising means for requesting said transmission means during the use of said transmitter (s) and making the operation of said transmission means thus requested detectable.

 The invention also relates to a movable member motor, in particular intended for implementing the method described above, said engine comprising means for processing command orders for controlling the movements of the movable member, said processing means being able to operate in two different modes, one known as normal, in which it takes into account all the orders arriving at it, the other known as security, in which it compares orders from a first type of transmitter and the

<Desc / Clms Page number 3>

 normally redundant orders from a second type of transmitter, and adapt the movements of the movable member to the results of the comparison.

 The invention will be better understood on reading the following description, accompanied by the accompanying drawings, in which: - Figure 1 illustrates a first example of implementation of the method according to the invention, - Figure 2 illustrates a second example of implementing the method according to the invention, - Figure 3 schematically illustrates an embodiment of the transmission means used by the invention.

 The invention relates first of all to a method of controlling a movable member.

 As illustrated in FIGS. 1 and 2, it is, in particular, a bi-directionally movable member 1 such as a blind, rolling shutter, grid or the like allowing, for example, deployment / folding, according to the arrow marked 2, a tarpaulin or apron 3 around a drum 4, driven in rotation in one direction or the other about its longitudinal axis by a motor 5.

 According to the invention, control commands 6,7 for its movements are transmitted to said mobile member 1, on the one hand from at least one transmitter 8 and on the other hand from transmission means 9. The latter are intended to relay to the mobile member 1, so-called safety messages from means 10 for detecting a dangerous situation.

 Said control orders 6,7 are transmitted to said mobile member 1, for example, remotely, that is to say wirelessly, in particular by radio wave or the like.

 Said control orders 6,7 are, in particular, deployment or folding orders for the tarpaulin or deck 3 and / or stop orders for these movements.

 The orders from the transmitter (s) 8 are given, for example, by a user.

 Means for detecting a dangerous situation

<Desc / Clms Page number 4>

 allow for example, to give an indication of the force of the wind acting on the tarpaulin or deck 3. Their location and structure will be developed later.

 They deliver messages, in particular, about folding the blind or the shutter. In the case of a grid, it may also be a stop order during deployment. In all cases, the nature of the message will be adapted to the context so as to respect user security.

 According to the invention, in order to be able to quickly detect the failures of said transmission means 9, they are solicited during the use of said transmitter (s) 8 and their operation is made detectable, in particular visually and / or acoustically.

 In this way, each time the movable member 1 is used, the proper functioning of the transmission means 9 is verified, and one is thus immediately notified in the event of a problem.

 For this, use is made, for example, of said transmission means 9 for relaying orders 6, said to be issued, originating from said transmitter (s) 8, in the form of order 7, said to be transmitted, in a manner at least partially identical to that of which the messages are relayed and a detectable signal is delivered as a function of said transmitted orders 7.

 By at least partially identical, it is meant that one uses, in whole or in part, the same components and / or programs of the transmission means 9 to relay said orders issued 6 and / or the security messages. The transmitted orders 7 contain the same movement instructions as those contained in said issued orders 6.

 The detectable signal making it possible to highlight any failures of the transmission means 9 will be defined, for example, by the behavior of the mobile member 1 itself, taking into account at least said transmitted orders 7 to determine its movements.

In this way, if these do not correspond to those expected, taking into account the order issued 6, we can conclude that a fault exists. Signaling light-emitting diodes may also be used.

<Desc / Clms Page number 5>

 According to a first embodiment illustrated in FIG. 1, said movable member 1 is set in motion according to the instructions contained in said transmitted orders 7, only. We can then conclude that the transmission means 9 are functioning properly if the mobile member responds to the orders issued 6.

 According to another embodiment illustrated in FIG. 2, the content of the orders issued 6 and of the orders transmitted 7 is compared and the movements of said movable member 1 are adapted to the results of the comparison.

 If the two messages are identical, the requested movement is carried out. If they are different, the reaction will be, for example, a withdrawal and / or a refusal to deploy.

 The advantage of this embodiment is that it avoids the risks of remaining in the deployed position in the event of failure of the transmission means 9, for example for reasons of battery.

 In order to avoid a complete deployment of the shutter of a rolling shutter in the event of a failure of its transmission means 9 after a deployment order has been given, it may be necessary to repeat the bursts of transmitted order 7 in order to reach the end position.

 According to a particular embodiment, said orders issued 6 are processed at the level of the transmission means 9 as a function of identification codes of the said transmitter or transmitters 8. It is thus possible to select the transmitter or transmitters 8 authorized to actuate the mobile member.

 The identification code or codes of said emitter (s) 8 may also be processed at the level of said mobile member 1 to decide whether or not to take orders issued 6 into account.

 It may be the same for orders from the transmission means 9, that is to say, said transmitted orders 7 and / or security messages, by providing the transmission means 9 also with one or more identification codes.

 This avoids that transmission means 9 of a movable member 1 controls the movements of another movable member. We allow

<Desc / Clms Page number 6>

 also the mobile unit 1 concerned to differentiate the orders issued 6 from the orders transmitted 7.

 The invention also relates to a device for controlling a movable member, in particular a blind and / or rolling shutter, possibly intended for implementing the method described above.

 It comprises, on the one hand, one or more transmitters 8 and, on the other hand, transmission means 9, intended to relay to the mobile member, so-called security messages originating from means for detecting a situation dangerous 10. The said transmitter or transmitters 8 and said transmission means 9 are capable of transmitting to said mobile member 1, orders for controlling its movements.

 Said emitter (s) 8 consist, for example, of a box provided with control buttons actuating processing means allowing the transmission of the orders issued 6.

 Said detection means 10 are provided, for example, on the frame of the movable member 1, that is to say, in the case of a blind on its deployment arms, not shown, and / or its terminal bar 11. These may be wind detectors, in particular vibration detectors, or the like. They are capable of delivering a security message which can be relayed by said transmission means 9.

 As illustrated in FIG. 3, the latter consist, for example, of processing means 12 connected to the detection means 10 for the circulation of safety messages and of a unit 13 for issuing control orders to the member. mobile 1.

 According to the invention, said control device further comprises means for requesting said transmission means 9 during the use of said transmitter (s) 8 and for making their operation detectable.

 For this, said transmission means 9 are, for example, provided capable of relaying the orders issued 6 coming from said emitter (s) 8 in the form of order transmitted 7 in a manner at least partially identical to that of which the security messages are relayed . Said means of

<Desc / Clms Page number 7>

 transmission 9 include, for this purpose for example, a reception unit 14 connected to said processing means 12.

 Said device also comprises means for delivering a detectable signal, a function of said transmitted orders 7. It may be means 15 for taking into account at least said transmitted orders 7 to determine the movements of said movable member 1.

 The latter consist, for example, of processing means 16, capable of carrying out the reception of said transmitted orders 7 at least and of transforming them into operational orders executable by the movable member 1, more particularly by its motor 5. They are located , for example, in the drum 4, near said motor 5.

 According to a first embodiment, corresponding to FIG. 1, said processing means 16, associated with the motor 5, are able to take into account only the messages transmitted 7.

 According to another embodiment, corresponding to FIG. 2, said processing means 16, associated with the motor 5, are able to compare the content of said orders issued 6 and said orders transmitted 7 and to adapt the movements of said movable member 1 to the results of the comparison, to operate according to a so-called security mode.

 According to a particular implementation of the invention, said processing means 16, associated with the motor 5 are capable of operating in two different modes, a first mode, called normal, in which they take into account each order individually and a second mode corresponding to said security mode.

 For this, said processing means 16, associated with the motor 5, are provided, for example with means for configuring their operating mode. It will be, in particular, a memory location of said processing means 16, the value of which will determine whether they must operate in normal mode or in security mode.

 Switching from one mode to another can be carried out by direct intervention at the level of the drum 4 or by means of the

<Desc / Clms Page number 8>

 transmitters 8, provided capable of placing said processing means 16, associated with the motor 5, in a configuration mode in which their operation can be programmed. For this, the said transmitter (s) 8 are provided, for example, with switches whose positions determine the nature of the message sent 6.

 It should be noted that an engine 5 comprising processing means 16 as described above and more generally suitable, in safety mode, for comparing the orders originating from a first type of transmitter and the orders, normally redundant, coming from a second type of transmitter, and adapting the movements of the movable member 1 actuated by said motor to the results of the comparison, could find many other applications and is also the subject of the invention.

 In particular, it makes it possible to have a single engine which can be used both for conventional applications with a single family of transmitter and for more advanced applications in which information must be processed from several different families of transmitters, for example for security reasons, switching from one mode of use to the other is carried out by simple configuration of a memory table.

 However, the said transmitter (s) 8 and / or the said transmission means 9 are able, if necessary, to include identification codes in the orders sent 6,7 to the mobile unit 1. Said processing means 16 associated with the motor 5, may then be able to take into account said orders 6,7 as a function of said codes, so as to allow their recognition.

 The said identification code or codes are contained, for example, in memories specific to each transmitter 8 and / or to the transmission means 9.

 Naturally, other embodiments within the reach of ordinary skill in the art could have been envisaged without departing from the scope of the invention.
