Definitions

  • the invention relates to a safety device for a motorized roller shutter or the like comprising means delivering an electrical signal representative of the movement of the roller shutter and a logic processing unit capable of working in learning mode and in use mode, by sampling, and comprising means for memorizing, in learning mode, value samples corresponding to the signal samples and means for comparing, in use mode, these memorized value samples with the value samples obtained in use mode, and means for controlling stopping of the shutter motor when the difference between the value of the sample obtained in use mode and the value of the stored sample is greater than a determined difference.
  • roller shutter means any closing element which can be rolled up, that is to say both an element consisting of blades hinged together and a canvas or the like.
  • a device of this type is described in patent US-A-4,831,509 for controlling a door of the roll-up type.
  • the signal representative of the movement of the door is obtained by means of a position encoder coupled to the door winding drum and optoelectronic sensors placed on the path of the door and detecting the passage of marks, in particular of particular blades, and sending pulses to the encoder, each time a mark is passed.
  • the signal delivered by the encoder is used by a microprocessor which proceeds by sampling the stroke divided into segments and sectors to determine speed changes on the door's travel sectors. When the change in speed measured in a sector is outside the fixed limits, the device concludes that there is an obstacle, stops the engine and reverses its running.
  • This device has various drawbacks.
  • the encoder must be necessarily on the axis of the winding drum or coupled to this axis, which is not always possible, due to lack of space.
  • the sensors must be placed in the immediate vicinity of the roll-up door on which the markers are arranged and as close as possible to them, which is difficult, because because of the technique used, the movement of the roll-up door n is not always very straight.
  • the markers they must be located on the door itself and, given their exposure, they are subject to degradation and fouling, which is detrimental to the proper functioning of the device and therefore to safety.
  • the electrical connection must be comfortably protected.
  • This prior device also requires that the "high”, ie "wound”, automatic stopping point be precise, since it is from this point that the device successively establishes the displacement sector after displacement sector, that is to say of unwinding, the average speed changes which will then be compared to the speed changes measured in operating mode. If the "high" breakpoint moves, the measured speeds also move and the comparisons are distorted, which is detrimental to the fidelity of the device. It can also be noted that the program linked to this device derives its complexity from the routines necessary for the permanent adaptation of the reference speed characteristics. Finally, the result obtained by this prior device is not satisfactory if we are dealing with rolling shutters with telescopic openwork slats, which is most of the domestic roller shutters. Indeed, in this case, the sensor being necessarily located near the winding axis, the device can only detect an obstacle when the blades located under the sensor are stacked tight, that is to say when the obstacle supports the full weight of the blades located under the sensor.
  • the object of the present invention is to provide a device which overcomes the drawbacks of the known device, and more particularly a device which is easy to implement and which requires no or very few arrangements on the shutter itself, in particular no precise mechanical part and tricky to install.
  • the device must be safe to operate regardless of the environment and conditions of use.
  • the safety device is characterized in that the means delivering the electrical signal representative of the movement of the shutter comprise a pulley on which is wound a flexible element whose free end is connected to the end of the shutter, so that the unwinding of the rolling shutter causes the unwinding of the flexible element, an elastic means ensuring the rewinding of the flexible element on its pulley during the winding of the rolling shutter and a signal generator mechanically connected to the axis of the pulley and delivering an electric tension representative of the speed of rotation of the pulley, and that the logic processing unit comprises means for sampling the electric signal delivered by the signal generator.
  • the electrical signal delivered by the signal generator mechanically connected to the axis of the pulley must simply make it possible to immediately detect a sudden and significant variation in the speed of rotation of the pulley when the shutter is lowered.
  • This signal generator can therefore be of different types, provided that it transmits information representative of this sudden deviation.
  • a Hall effect sensor is used, for example a synchronous motor used as a generator.
  • a strain gauge combined with a spring gradually stretched by the rotation of the pulley.
  • the samples memorized in training, measured and compared can be of different types. For example, we can compare the speed variations between two successive measurements ( ⁇ v) or compare the successive speed measurements, by simply stopping the motor when the measured speed is substantially equal to 0, while the speed memorized in mode learning for the corresponding time is still different from 0, or, by reading successive speeds, calculate the average slope of the speed curve between the top and bottom positions of the shutter and, this average slope being stored, measure and calculate, in operating mode, the speed variations ( ⁇ v) between two successive measurements and compare them with the average slope, the motor being stopped when the deviation is very large, which means that the shutter has encountered a obstacle which strongly braked it, if not stopped.
  • FIG. 1 diagrammatically represents an installation comprising a rolling shutter 1 consisting of juxtaposed transverse blades and winding on a motorized winding tube 2 mounted in the upper part 3 of the doorway 4 of a window.
  • the winding tube 2 is driven by a geared motor 5 as described by example in patents FR 2 480 846 and 2 376 285.
  • the gear motor 5 is mounted inside the winding tube 2 and drives the latter by means of a pulley 6 secured to the winding tube 2

  • the installation also includes an electronic control unit 10.
  • a first embodiment of the sensor 7 is shown in Figure 3. It consists of a housing 11 mounted at the end of the winding tube 2 and containing: a shaft 12 freely mounted in the housing, a pulley 13 fixed on the shaft 12 and on which the cord 9 is wound, and two flat springs 14 and 15 in a spiral, arranged on each side of the pulley 13 and one end of which is fixed to the shaft 12 and the other end is fixed to the housing 11.
  • a toothed wheel 16 meshing with a pinion 17 secured to the shaft of a small synchronous motor 18 constituting a signal generator.
  • the motor 18 is connected by two wires 19 to the electronic unit 10.
  • the springs 14 and 15 are return springs which have the function of rotating the shaft 12 to rewind the cord 9 on the pulley 13 when the shutter is raised. rolling 1.
  • the two springs 14 and 15 having the same function, a single spring would be sufficient. During the rolling shutter 1, the cord 9 therefore has the effect of driving the pulley 13 and consequently the synchronous motor 18, by multiplying the speed of rotation of the winding tube 2.
  • the electronic unit 10 shown schematically in FIG. 2, comprises a logic processing unit (ULT) 20, a stabilized power supply 21, an output interface 22, an analog / digital converter 23, contacts up M, down D and selector mode S, the two-wire input 19 connected to the sensor 7, a two-wire input 24 connected to the P / N power supply, a two-wire output 25 connected to the gear motor 5 and a single-wire output 26 connected to an alarm.
  • the interconnections between the various elements listed are established according to the diagram shown in Figure 2 and will not be described in detail.
  • the stabilized power supply 21 is provided to supply a stabilized TBT power supply to the analog / digital converter 23, to the output interface 22 and to the ULT 20.
  • the A / D converter 23 is provided to convert the analog signal coming from the sensor 7 in digital signal.
  • the output interface 22 is provided to supply power to the geared motor 5, as well as to an alarm in reaction to orders from the ULT 20.
  • the ULT 20 consists of a computer 27, for example 8051 MOTOROLA, a random access memory RAM 28 and an electrically erasable EEPROM read-only memory 29.
  • the EEPROM memory 29 contains memory boxes for the storage, in learning mode, of the values of the signals received from the sensor 7 and read when the shutter 1 is subjected to a descent command, and of the value of the average slope calculated between the last value read and first value read (PMA).
  • the RAM memory 28 contains memory boxes for storing, in use mode, the values of the signals emanating from the sensor 7 and read when the shutter is subject to a descent command, and, if applicable, the value of the variation in the slope of the value curve between the last value read and the first value read (PMU).
  • the computer 27 includes a non-volatile memory containing memory boxes in which the safety program is stored, the value of the difference k1 max accepted between the elementary slope PEU calculated in use mode and the average slope PMA calculated in learning mode, the curve of the values, the Up / Down subroutines that can be activated by the Up / Down contacts M and D, and the Stop plus ascent, Alarm subroutines, can be activated by the safety program. These subroutines have the effect of activating the corresponding outputs of the computer 27 and, via the output interface 22, of controlling the descent, ascent, stop and ascent of the shutter 1 or command the triggering of an alarm.
  • the ULT 20 is programmed to work in two modes, one for learning and the other for use, and for sampling, that is to say sequentially and repetitively, when the shutter is subjected to a descent command: reading two successive values of the signal delivered by the signal generator 18; calculating the elementary slope of the signal curve corresponding to the variation between these two values; memorize the signal values when the slope is different from 0 in learning mode.
  • the ULT 20 is programmed to calculate the average slope corresponding to the variation between the first stored value and the last.
  • the ULT 20 is programmed to activate a subroutine of shutter up and up if the last signal value recorded at this time is different from the last signal value recorded in learning mode.

  • the signal generator here consists of a strain gauge 30 associated with the spring 15 and measuring the mechanical tension of this spring 15.
  • This strain gauge 30 is connected by a four-wire line 19 'to the control unit 10 , two wires coming from the stabilized power supply 21 and the other wires being connected to the A / D converter 23.
  • the roller shutter 1 is wound at the stop point O.
  • the lower stop point of the auxiliary automatic stop device is adjusted so that the final blade 8 of the roller shutter rests on the base of the doorway 4 of the window.
  • the program will be designated by PRG and the sub-programs by SPRG.
  • the safety PRG takes place and instruction 31 scans the M / D contacts; instructions 32 and 33 test that none of these contacts is activated, then the PRG closes on instruction 31.
  • the user activates the mode selector contact S, then activates the Down contact D.
  • Instruction 33 tests that the Down contact D is activated;
  • instruction 34 activates the descent SPRG which causes the rolling shutter 1 to unfold. It moves downwards and drives, by its blade 8, the cord 9 connected to the pulley 13 which leads to in turn the synchronous motor 18 which then delivers an electrical voltage as a function of the speed of rotation of the pulley 13.
  • the gear motor 5 having a constant speed and the winding diameter decreasing with the unwinding, the linear speed of descent of the flap rolling 1 decreases with the unwinding and the speed of rotation of the pulley 13 also decreases regularly so that the electrical signal delivered by the synchronous motor 18 also decreases regularly, the slope between the successive values of the successive measured signal being substantially constant, but different from 0.
  • Instruction 35 tests that the ULT 20 is in learning mode; instruction 36 reads two successive values of the signal, then instruction 37 calculates the elementary slope PEA between two successive values of the signal.
  • Instruction 38 tests that PEA is different from 0, which is the case throughout the descent of the shutter 1, because, in learning mode, care is taken to ensure that nothing comes to disturb this descent.
  • Instruction 40 then calculates the average slope PMA corresponding to the total variation of the signal value between the first value and the last value stored 39 in EEPROM, then instruction 41 memorizes this average slope in EEPROM also. Instruction 42 switches the device to use mode, then the safety PRG closes on instruction 31.
  • the user controls the winding of the shutter 1 to its top stop point, by activating the Up contact.

  • instruction 48 calls instruction 49 which activates the shutter stop and raise SPRG. If the final blade 8 arrives on the base, the instruction 48 tests that VUT is equal to VAP and the safety PRG closes on instruction 31, the device for automatically stopping the winding means taking care of stop the roller shutter at its bottom stop point.
  • the signal generator was a synchronous motor 18.
  • the signal generator consists of the strain gauge 30, the spring 15 provided with the gauge 30 receiving an initial arming, the value of the signal delivered by the strain gauge 30 is always different from 0.
  • the stress of the spring 15 does not change, the signal is therefore constant, while in motion, the speed of rotation of the pulley 13 decreasing regularly, the curve of the spring 15 is substantially linear and the signal increases regularly. It follows that, as in the previous mode, the slope of the signal is zero at standstill and substantially constant and equal to the average slope in motion. The operation of the device is therefore identical to the operation described.
  • the ULT 20 can also be programmed to stop the roller shutter in the high rolled up position.

On the climb, we consider that there is no obstacle and therefore a variation means that we are at the top. This is the only possibility provided by the ULT. There is no need to distinguish between an obstacle and a complete winding. The addition to the program diagram of FIG. 5 is shown in FIG. 7.

  • FIG. 14 represents the diagram of the programs of a third embodiment combining the sensitivity of the first embodiment (FIG. 9) with the simplicity of the program of the second embodiment (FIG. 10).
  • the measured speeds are directly compared with the speeds stored in learning mode.
  • the speed of the pulley 13 being regularly decreasing, it is also sufficient to calculate the average slope by means of the first and the last stored speed value.
  • the ULT 20 is programmed, in learning mode, to sequentially and repeatedly, when the shutter is subjected to a down command, read a value of the signal delivered by the asynchronous motor, memorize this value as long as it is different from 0 or, this value being equal to 0, calculate the average slope between the first and the last stored value.
  • the logic processing unit is programmed to ensure the automatic shutdown of the roller shutter in the low position and in the case where the automatic shutdown of the roller shutter is ensured by a mechanism driven with the winding tube and actuating a limit switch, it is practically impossible to distinguish an obstacle from the bottom stopping point, if this obstacle is near the bottom stopping point and occupies a height of less than 20 mm from the point of stop low. Therefore, in the case where the automatic stop at the bottom stop point is ensured by a device mechanical, such a small obstacle is ignored. This is particularly the case of a rolling shutter where the safety program tests that the speed in use mode is equal to the speed in learning mode when the first blade of the rolling shutter comes up against the base.
  • the end-of-travel stop device will only stop the motor when all of the shutter blades are stacked on top of each other. If the small obstacle ignored is, for example a finger, in particular a child's finger, this finger can be trapped by the roller shutter. If the stop at the low point is ensured by the logic processing unit, the stop at the low point will be too early and the roller shutter will not be completely closed.
  • the logical processing unit is also programmed for, in learning mode, as long as the elementary slope of the curve of the samples is equal to zero or when the value of the samples is equal to zero, depending on the execution mode, calculate the average of the last n stored sample values and, in use mode, when the difference between the elementary slope between the signal samples and the average slope calculated in learning mode is greater than a determined value or when the value of the sample is close to zero, depending on the execution mode, calculate the average of the last n values of stored samples and compare this average with the average of the last n values of signal samples calculated in learning mode and activate the subroutine of engine stop and ascent when the difference between the compared values is greater than a determined value.
  • n will be chosen equal to approximately 20 and the critical deviation will be chosen to be approximately 10% of the average value calculated in learning mode.
  • This enhancement of the program makes it possible to detect obstacles occupying a height of approximately 5 mm from the bottom stopping point. A roller shutter meeting a finger will stop and go up.
  • FIGs 15, 16 and 17 respectively represent the diagrams of the instructions of the security program according to Figures 5, 10 and 14 supplemented as indicated above.
  • the diagram represented in FIG. 15 corresponds to the diagram represented in FIG. 5, to which the instructions 64 and 65 have been added.
  • the instruction 64 between the test instruction 38 and the instruction 40, is an instruction for calculating the average value (VMAP) of the n last values read in learning mode and stored in 39.
  • Instruction 65 placed between test instruction 45 and instruction 47 ′, is an instruction for calculating the average value (VMUT) of the n last values read in use mode and stored in 46.
  • Instruction 47 of the main patent application has become instruction 47 ′ because, in this new mode of execution, it is an instruction for comparing the last average VMUT calculated with the last average VMAP stored. Consequently, instruction 48 tests whether VMUT ⁇ VMAP.
  • the instruction 48 If the instruction 48 detects VMUT ⁇ VMAP, that is to say VMUT ⁇ 0.9 VMAP, the instruction 48 calls the instruction 49 which activates the shutter stop and raise subroutine.
  • the logical processing unit can of course also be programmed to provide the additional functions described above.
  • FIG. 16 represents the instruction diagram of FIG. 10 supplemented by the same instructions 64 and 65.
  • the instruction 64 is arranged between the test instruction 38 ′ and the instruction 42.
  • the instruction 65 is arranged between the 'test instruction 45' and instruction 47 'identical to instruction 47' in Figure 15.
  • the diagram represented in FIG. 17 corresponds to the diagram represented in FIG. 14 supplemented by the same instructions 64 and 65.
  • the instruction 64 is placed between the test instruction 48 ′ and the instruction 40.
  • the instruction 65 is arranged between test instruction 45 and instruction 47 'identical to instruction 47' in Figure 15.
