Description

The invention relates to a method for controlling an installation of

  operation of a closing element, in particular a commercial gate, driven by an actuator provided with a command receiver and the activation of which is controlled by a command transmitter provided with at least one control on which an action causes the emission of a movement order of the closing element, the installation comprising at least one safety sensor and means for detecting the availability of this or these sensors. It also relates to a safety installation for the operation of a closure element, in particular a commercial gate, driven by a

  actuator comprising an order transmitter provided with a control element and capable of transmitting control orders, an order receiver connected to the actuator and at least one safety sensor and means for detecting the availability of the or sensors. 15 The closing devices for industrial and commercial premises are highly regulated. There are standards, in particular European ones, which impose, given the weight of the closure elements and their environment, safety devices, making it possible in particular to prevent the elements from falling or to detect obstacles.

  Most industrial or commercial closing elements, such as grids, are controlled by a so-called "dead man" control device. Their opening and closing movements cannot be carried out according to automatic cycles. A user must necessarily be present next to the device during these movements, in order to be able to intervene in the event of an incident. These devices use so-called momentary position switches causing the element to move only when they are actuated. In this way, it is possible to comply with the safety standards in a simple and inexpensive manner.

  2.S649. 12GB. 466. dpt. doc Closing devices with additional functions would be desirable, but the complexity of assembling a substantial set of peripherals (such as sensors, switches, 5 safety accessories, lighting, alarms, etc.) to different types of actuators to alternating or direct current, low voltage or high voltage, limits their development.

  Installations use electromagnetic wave links 10 between the peripherals and the actuator, to simplify the wiring, but they hardly meet the conditions imposed by the standards.

  It is also known, in various systems, to collect a set of sensors on an interface so as to identify and monitor them easily. Such a system intended for controlling a garage door by an actuator and comprising a set of safety sensors is described in patent application EP 0 801 260.

  The sensors are connected to standard connectors, such as telephone connectors, to simplify wiring. These sensors are connected in series, so that a single monitoring signal makes it possible to detect an error or an error message originating from at least one of the sensors, and to cut the power supply to the actuator. This system has a major drawback. It works all or nothing so that if a sensor fault or problem is detected, the actuator is automatically disabled until the fault or failure has been remedied, without further recourse.

  Furthermore, there is known from patent EP 0 839 980 a drive device for a garage door which takes account of the presence or absence of a security sensor. Indeed, in the presence of one or more safety devices, the actuator operates at its maximum power.

  2.S649. 12GB. 466.dpt. doc By cons, if no safety device is detected, limiting means acting on the actuator are provided to limit the power or force or the torque it applies to the door. This operation under limited conditions does not replace the visual control of the drive device to avoid a possible incident.

  The object of the invention is to implement a method for controlling a closure installation improving the methods known from the prior art and overcoming the problems mentioned. In particular, the invention proposes to implement a method of controlling a closing installation allowing the operation of the closing element when one or more sensors are faulty while eliminating the risks of incident related to the closing installation. The invention also proposes a closing installation allowing the implementation of such a control method.

  The method according to the invention is characterized in that it comprises at least: a) a first mode, called normal operation, in which a temporary action on the control element causes a continuous movement of the closing element , and b) a second mode, called degraded operating mode, in which a continuous movement of the closing element requires a continuous action on the control element, the operating mode being selected according to the availability of the sensor or sensors determined by the means of detection.

  The normal operating mode is implemented as long as the detection means validate the availability of all the sensors, of a group of sensors or of at least one sensor.

  2.S649. 12EN.466.dpt.doc The degraded operating mode is implemented as soon as the detection means detect a service fault or an absence of all the sensors, a group of sensors or at least one sensor.

  In the degraded operating mode, the movement of the closing element can be carried out at limited torque and / or speed.

  The installation according to the invention is characterized in that the command receiver is connected to means for interpreting the command sent by the command transmitter as a function of the availability of the sensor or sensors detected by the means detection.

  The order transmitter can be a key reverser.

  The means for detecting the availability of the sensor (s) may comprise means for recognizing the type of sensor connected and / or means for testing the state of service of this or these sensor (s).

  The security installation may include a programming device provided with at least one user interface and / or means for connection to an external programming device.

  It can include security accessories and / or alarm devices and / or lighting devices and / or emergency power.

  The security sensor (s) and / or other accessories, alarm or lighting can be linked to the other elements of the installation by means of 30 standard connectors.

  The installation can comprise at least two types of order transmitters, one type being in a fixed position and the other being in a momentary position, the interpretation means transmitting only the orders originating from momentary position transmitters when the means of detection 5 detect a service fault or an absence of all the sensors, of a group of sensors or of at least one sensor.

  The accompanying drawing shows, by way of example, an embodiment of the method according to the invention.

  Figure 1 is a diagram of the closure installation according to the invention.

  FIG. 2 is a flowchart of the method for controlling the device according to the invention.

  The closing installation 1 represented in FIG. 1 is intended to equip an opening of an industrial or commercial premises. It includes a control unit 25, preferably comprising three boxes 3, 4 and 5. A first so-called connection box provides the interface with 20 different peripherals such as sensors 20, command transmitters 24, security accessories 23 , lighting devices 22 and alarm devices 21 and with an actuator 6 driving a closing element 7.

  The peripherals are of a type known in the field and their description will not be developed. They may, for example, be safety edges, photoelectric cells, presence sensor, lighting lamps, fall arrest systems, command transmitters, etc. A distinction is made between the control elements of the transmitters of orders, of the elements with fixed position and of the elements with momentary position.

  When acting on a fixed position element, a press is enough to make 2.S649. 12FR.466.dpt.doc execute a complete command such as raising the low end position to the high end position of the closing element. When acting on a momentary position element, the support must be maintained throughout the duration of the execution of the command. The issuers of orders may, for example, consist of key reversing switches. Alternatively, an order transmitter can be without contact with the connection box 3 (electromagnetic communication for example).

  Indeed, a certain advantage of the invention is the possibility of using wireless remote controls, in particular transmitters of radio orders, the orders of which will be interpreted, according to the invention, according to the availability of the or sensors, like any other command transmitter.

  The peripherals are connected to the connection box 3 by standard connectors at specific locations or not of the box. Thus, the installation and modification of the connections can be carried out in a very short time. The connection box comprises a plurality of sockets capable of receiving standard connectors of the telephone connector type. These sockets are identified or not by 20 pictograms representing the peripherals to be connected to them.

  The sensors are linked to the connection box 3 by means of detection 28 of the availability of the sensors. These means comprise means 29 for recognizing the type of sensor connected and means 30 for testing the service status of the sensors.

  An available sensor is therefore a sensor whose presence is detected and in working order.

  The connection box 3 is preferably located near the closure element 7 and is connected by wire to a configuration box 4. 30 2.S649.12EN.466.dpt.doc It is therefore possible to provide a connection box 3 in which any peripheral is connectable to any socket of the housing and cooperating with electronic means for identifying the peripherals.

  The configuration box 4 is connected to a mains supply 11, preferably via an emergency backup unit 12, of the inverter type.

  Several connectors on the configuration box 4 can also allow connection to different other sources of alternating, direct, high voltage or low voltage electrical energy.

  The actuator 6 comprises an order receiver 26 connected to means 27 for interpreting command orders. Thus, as a function of the information that the interpretation means 27 receive means 28 15 for detecting the availability of the sensors 20, they interpret the same command order differently.

  The actuator 6 and possibly certain peripherals then react differently to the actions exerted on the control elements of the command transmitter 24.

  By way of example, if a sensor of the safety edge type is detected as being out of service, the downward movement of the closing element can only be implemented in the presence of a person who can verify in a manner physical absence of obstacle or react in the event of an incident. This is achieved by modifying the interpretation of an order received following an actuation of a control element such as a key reversing switch. On the other hand, if a photoelectric cell type sensor is still available, the installation may, despite the fault with the safety edge, operate without visual inspection.

  2.S649.12EN.466.dpt.doc If the upward movement of the closing element normally follows the entry of a code on a keypad of the digicode type, in modified operation, entry of the code does not will be more sufficient, but a continuous press on one of the keys on the keyboard for example will allow the execution of this command.

  The modification of the interpretation of the control commands can also act on the speed of movement of the actuator, on the frequency of acoustic or visual signals, in the manner of an alarm, or on a reversal of the direction of the direction. actuator.

  A programming unit 15 is linked to the configuration box 4.

  This programming unit 15 is provided on the one hand with an interface 13 of the keyboard type and, on the other hand, means of connection to an external programming member 14 to allow the configuration of at least part of the device. .

  This programming unit is connected to a microcontroller 9.

  The configuration notably makes it possible to determine the various possible safety sensors or that the user wishes to connect to his installation. It is also possible during configuration to determine whether this interpretation of the command commands occurs as soon as a safety sensor is detected as not available or when a certain number or all of the sensors are detected not available.

  Alternatively, the connection box 3 and the configuration box 4 share the processing unit.

  Insofar as the detection of sensors and / or peripherals is automatic, the savings in installation time are significant.

  The programming unit 15 can be connected by a GSM type line to an external programming device. This external organ can 2.S649. 12GB. 466. dpt. doc may consist of a website on which the installer, manufacturer or user can obtain configuration assistance and customer support in a dedicated dedicated area. Additionally, this connection offers the possibility of performing preventive maintenance, remote fault diagnosis or rapid maintenance.

  The configuration can be organized on two levels: for example a first level accessible to the user and a second level accessible exclusively to the manufacturer.

  The programming unit 15 can also have downloading means allowing the downloading of installation programs or of later versions of control programs.

  According to an alternative embodiment of the installation, the processing unit 8 is integrated into the connection box 3 and connected to the configuration box 4.

  Preferably, the control unit 2 comprises an additional information box 20 5. This box contains a display device, in particular light-emitting diodes, so as to visually transcribe the state and the information given by the sensors and other peripherals.

  The advantage of decomposing the device into three connection, configuration and display boxes lies in their possibility of arrangement in the premises. The connection box is preferably placed close to the closing element to facilitate the passage of cables. The configuration box can be placed in a more accessible location to allow easy configuration, maintenance and connection to the power supply network. The 2.S649.12EN.466.dpt.doc display unit can be placed in a place where it will be easy to read, for example near a cash register in the case of commercial premises.

  In a first phase 100, of the flowchart for controlling the closure installation shown in FIG. 2, a test is performed by the detection means 28 to identify the available sensors.

  If one or more sensors are detected as not available, phases 101 and 102 are executed. In these phases respectively, any command in progress is stopped, then the installation operates in degraded mode, that is to say that the command commands are transmitted to the actuator as long as the user acts on the element. control. This operating mode of the closing installation corresponds to a conventional "dead man" command.

  If the sensors are present and in working order, then a phase 103 is executed. In this phase, automatic control orders are transmitted to the actuator during an action on the control element. In parallel, in a phase 104, the information supplied by the sensors is analyzed and any fault (obstacle, overvoltage or other) causes for example either the stopping of the actuator or a reversal of the direction of rotation during a phase 105. This sensor control is known in the art and will not be developed in more detail.

  Phase 100 is reiterated during any command and a detected sensor modification can cause a mode change during the command.

  The different phases can be accompanied by an acoustic signal or by special lighting, giving information of the correct operation or alarm type.

  2.S649. 12EN.466.dpt.doc If the sensor test reveals an insufficient number of safety sensors or a fault in one of these sensors, the only way to execute a command is to actuate the control element 5 for the duration of the execution of this command. This implies the presence of a user near the door, who can monitor the operation of the door and react in the event of an incident.

  The invention also applies to the case in which the installation 10 has several transmitters of orders with different (fixed / momentary) operation. In this case, the interpretation means transmit only the orders coming from the transmitters at the momentary position and not those coming from the transmitters at the fixed position if the operating mode is the so-called degraded mode.
