Definitions

  • the present finding concerns an integrated device for obstacle detection and travel indication for a motorised gate or the like, with particular reference to sliding and swinging gates, barriers, automatic doors and the like.
  • the same standard forces at least one optical device for detecting obstacles to be installed, in many installation conditions.
  • the detection of obstacles is carried out by applying an electromagnetic beam in the infrared field, between a transmitting unit and a receiving unit, arranged at opposite sides of the opening, the access of which, is controlled by a barrier or by a gate.
  • the receiver When the infrared beam intercepts an object, the receiver sends a signal to the control unit, which is translated into a command to stop or reverse the motion of the motorisation unit.
  • many pairs of photocells are applied installed in various positions on the pillars of the access opening of the gate or door, on their inner or outer side and at variable heights according to the use of the gate.
  • indicator light devices which, synchronised with the movement of the door, warn the user that the opening or closing has begun, with the purpose of visually warning whoever is in the movement area of the gate.
  • indicator light devices consist of yellow-orange semi transparent dome lamps, illuminated with synchronised flashing lights, with variable frequency, in general of the order of one flash per second.
  • the light source consists of a common incandescent bulb or in some cases of LED lights, with a supply and control unit for synchronising the flashing, connected to the control station of the gear motor.
  • the purpose of the present finding is combining the obstacle detection function with the indicator function, such that the indicator function is also used for diagnosing the anomalous operation of the detecting device.
  • the light beam of which is suitably concentrated and directed by an optical deflector towards the area adjacent to the manoeuvring area of the gate.
  • One or more LED lights are used also with a function of diagnosing the anomalous operation of the detecting device, consisting of one or more pairs of infrared photocells.
  • the LEDs of the transmitter could be switched on, whereas the LEDs of the receiver could be switched off, this condition being sufficient to identify the condition of the interruption of the light beam by an obstacle.
  • the LED indicators In a system with many pairs of photocells, applied to the same access opening, it is possible to identify, through the LED indicators, which pair is engaged by an obstacle, or which pair of photocells has an anomalous or faulty operation condition. For example, if there are disturbances with the signal or if there is a misalignment between the transmitter and the receiver, when the gate receives the manoeuvre command, there is no actuation.
  • the asymmetric operation of the LEDs between the receiver and the transmitter which is essential for this invention, allows the installer and the user to immediately identify which pair of photocells is misaligned, or engaged. In a completely analogous manner, it is also possible to ensure diagnosing operations for a possible fault of the photocell.
  • the indicator LEDs for example, by varying the indication frequency, can help the installer carry out the correct centring of the pair of photocells during the first installation.
  • the access opening 1 is closed by a mobile barrier (or gate 2) actuated by the motor 6, through the rack 8, along the tracks 9 between the mechanical end stops 10.
  • the transmitter 3 and receiver 4 elements of the pairs of photocells which, through the infrared signal 5, intercept possible obstacles during the actuation, sending a suitable signal to the control unit of the motor 6, being also supplied by it, are fixed to the side pillars 11 of the access opening and to the columns 7.
  • indicator lights are not represented, since they are integrated in the transmitter and receiver elements 3 or 4 of the photocells, the detail of which is illustrated in fig.2.
  • Fig.2 represents a three dimensional exploded view of one of the elements 3 or 4.
  • the base 21 is fixed to a pillar 11 or to the column 7 with some screws passing through the holes 23 and acts as a support for the printed circuit 18, which rests on the support element 22 and is connected to the control unit of the motor 6 through a cable passing through the hole 23.
  • the printed circuit 18, represented in a simplified manner, has a photodiode 19 for the detection function, a terminal box 20 for the connection and a group 15 comprising at least one power LED for the flashing indication function.
  • the printed circuit 18 is closed by a lid 14, which has the function of directing the indicator light beam of the LEDs 15 passing in the holes 16 through the deflector 17 and of protecting the photodiode 19 from interferences through the cone 13.
  • the device is also closed by an outer lid 3 fixed by screws passing through the holes 12 and 25 on the tabs 24 of the base 21. All of this is closed in a semi-transparent outer half-shell 26, which allows the infrared beam to pass towards the deviator cone and simultaneously makes the indicator LEDs visible.
  • the integration of the indicator system with the device for detecting obstacles provides the user and the installer with the possibility of highlighting possible anomalies and faults of the device through the indicator device.
  • the activation of the flashing indicator device in the receiver 4 is enabled only if it is during the reception of an infrared signal 5. Therefore, if for some reason the activation of the door were to be carried out with the device for detecting obstacles not active, it would be highlighted to the user by the absence of flashing of the receiver, with however the flashing of the transmitter.
  • This logic is particularly useful in the case in which it is wished to connect many pairs of photocells in series, with the purpose of completely checking the manoeuvre area of the door, at different heights so that, in some cases these pairs of detection devices are also applied.
  • the graph a) represents the signal 5, obtained by the emission of infrared pulses of the transmitter 3, whereas the graph b) represents the emission of light pulses of the indicator light 15 of the transmitter 3 and of the receiver 4 (indicated respectively with reference numerals 27 and 28).
  • the transmitter 3, at the flashing of its indicator light 15, emits a packet of pulses P with a higher frequency (for example five pulse in Is, with a period ⁇ t1 20 ⁇ s), the receiver 4 once identified the packet of pulses, commands the flashing of its indicator light.
  • the flashing of the transmitter 3 and of the receiver 4 are synchronised with a frequency of 1/ ⁇ t, the delay between the first and the second flash being practically negligible.
  • the sending of the packet P occurs with a periodicity indicated in the figure as ⁇ T (generally of the order of 1 s).
  • Each pair of photocells can be associated with a characteristic transmission frequency of the infrared signal, set during installation, by associating, for example, each pair of transmitters 3 and receivers 4 with an address and allowing the receiver 4 to recognise the signal of the transmitter 3 associated with it. In this way, overlapping between the signal of different pairs of photocells, in the case in which installations are carried out on the same detection plane, is avoided.
