Definitions

  • the present invention relates to a modular device particularly for automatic doors.
  • Said electric/electronic panel controls and monitors the various movements or functions of the door, such as opening, closure, safety, speed of motion, actuation force, detection of obstacles in its path, etcetera.
  • peripheral devices which are known as motion sensors and are designated by the reference numeral 2; these devices are used in doors without access control to start the automatic opening motion of the door when a person, an object, a vehicle etcetera approach the door, presumably to pass through it.
  • the motion sensors 2 have a more or less conical sensing region with a range of up to a few meters.
  • This cone is directed downward obliquely, so as to adequately cover the area in front of the door.
  • motion sensors are installed on both sides of the door or only on one side; in the latter case, opening from the opposite side is operated by means of other devices, such as pushbuttons, key-operated switches etcetera.
  • Passive infrared sensors are devices which use the thermoelectric effect, which consists in the fluctuation of a certain electrical signal as a function of minute transient temperature variations detected by a particular detector element 4 and are caused by the incidence thereon of the infrared radiation emitted by the human body and conveyed by means of adapted lenses.
  • the detector elements 4 are mass-produced and are commercially available at relatively low costs: moreover, the signal generated by these detector elements does not require intensive processing and therefore the costs of the finished product are very low.
  • This technology suffers the drawback of having relatively long response times, of being sensitive to the degree of emissivity of the clothing worn by a person located in the detection region (dark clothing might not be "seen” by the device), of being sensitive to variations in the ambient temperature, and of being subject to false activations due to hot air currents, flames, etcetera in the vicinity of the device.
  • Active infrared sensors are instead devices which utilize the reflection, produced by the objects present within their range, of a beam of infrared light emitted by the device: the presence of a moving object within the range of the device causes variations in the reflected signal that reaches the device which are processed appropriately and, when they exceed a certain threshold, determine the release of a command on the part of the sensor.
  • This technology has the advantages of being insensitive to external heat sources, of being fairly fast and sensitive, and of using sturdy and relatively simple electronic components.
  • Microwave sensors instead use the so-called Doppler effect, which consists in measuring the frequency variation of a radio signal in the microwave band reflected by a moving object with respect to the frequency of the incident signal.
  • the device emits a beam of microwaves, receives the radiation reflected by the objects that are within the range of the device, determines their difference in frequency and, if this difference exceeds a certain threshold due to the motion of an object, it releases a command toward the automation system of the door.
  • the motion sensors 2 are currently provided as a single physical block, shown schematically in Figure 2; conceptually, these devices can be described by four functional blocks which are closely interconnected and are constituted by the actual detector element 4, by the block 5 meant to process the signal that arrives from the detector element 4, by the block 6 that is meant to release the actuation signals in output, and by the power supply block 7.
  • This conventional method therefore generally has considerable disadvantages as regards the cost of the execution of the two sensors, an internal one and an external one, which can be applied at the automatic door, and this increases the overall cost of automation.
  • the aim of the present invention is to solve the described problems, eliminating the drawbacks of the cited prior art and thus providing a device which allows to achieve considerable economic advantages with respect to the described conventional solutions.
  • an important object is to provide a device which allows to reduce the overall cost level of automation.
  • a further important object is to provide a device which allows to achieve door automation while allowing to use the most adapted technology according to specific requirements.
  • a further important object is to provide a device which allows to maintain a better overall aesthetic appearance for the door, accordingly without bulky containers for accommodating the sensor.
  • a further object is to provide a device which is reliable and safe in use.
  • a modular device particularly for automatic doors characterized in that it is constituted by at least one sensor module which can be associated with said door and can be connected by means of a cable to a separate management module which is adapted to power and/or detect the number and type of said at least one sensor module and the signal that arrives from it, processing it for transfer to suitable actuation means for moving said door.
  • 10 generally designates the modular device, which is constituted by at least one sensor module, designated by the reference numeral 2.
  • inventions 3 and 4 The embodiment with two sensor modules has been chosen in Figures 3 and 4; said modules may be of the passive infrared, active infrared or microwave type.
  • Each one of said sensor modules 2 is in turn constituted by a detector element 4 and by a minimal amount of electronic components 11 for processing the signal that arrives from each detector element 4 and such as to ensure in output a signal which is sufficiently robust and immune to electromagnetic interference.
  • Each sensor module 2 thus formed can be accommodated within a suitable container 12, which is very small and can therefore have a pleasant appearance and be easily concealed at a chosen point of the door despite being visible.
  • each sensor module 2 can be interconnected, by means of an adapted cable 13, to adapted inputs 14 provided in a management module 15.
  • Said management module can thus be placed at a different point than the one where the sensor module is applied.
  • the management module can thus be constituted by an electronic board which can be inserted in other units or placed inside an adapted independent container; it therefore contains a block 5 for processing the signal that arrives from the various sensor modules, which is able to detect, on the basis of manual settings or automatically, the type of detector element connected to each one of the inputs 14, accordingly applying the suitable method for processing the signal that arrives from it.
  • the management module can further contain a control output block 6 and a power supply block 7, both of which can be omitted and included within a generic block 16 which contains the door control logic system and is included, for example, in the electronic control panel of the automatic door itself.
  • each sensor module 2 and the management module is provided by means of a sturdy and low-cost cable, such as for example a commercial four-wire flat telephone cable: the connections at the ends of the cable are simple to perform because they use, for example, screwdown terminals or snap-in connectors of the telephone type.
  • a sturdy and low-cost cable such as for example a commercial four-wire flat telephone cable: the connections at the ends of the cable are simple to perform because they use, for example, screwdown terminals or snap-in connectors of the telephone type.
  • the length of the various connections can reach a few meters, thus allowing to locate the sensor module differently from the management module.
  • each type of sensor module 2 is determined almost exclusively by the cost of the detector element 4 located inside it, and the sensor module can be installed in a container which is the same for the three types of technology that can be used (active infrared, passive infrared and microwaves), so as to benefit from economy of scale in production.
  • the modular device can equally use mixed technologies (by utilizing detector elements constituted by an active infrared element, a passive infrared element or a microwave element), it allows to optimize the overall cost of each individual system, using the most suitable technology in each case.
  • the miniaturization of the sensor module provides a great advantage from the point of view of aesthetics and installation.
