Definitions
- the present invention relates to a door monitoring sensor according to the preamble of claim 1.
- a generic door monitoring sensor for moving mounting on a door leaf of a door to be secured, in particular an automatic swing door, is in DE 10 2007 025 394 A1 described.
- a transmitting unit for radiating light into a monitoring area on the floor in front of the door leaf and a receiving unit for detecting reflected back from the monitoring area light, wherein at least one triangulation sensor is formed by the transmitting unit and the receiving unit.
- mounting the transmitting unit and the receiving unit on the door leaf mounting means are present and for driving the transmitting unit, for evaluating measuring signals of the receiving unit based on learned data and for outputting control signals to a door control of the door to be secured is one with the transmitting unit and the receiving unit operatively connected control and evaluation available.
- the described optical sensor is suitable only for monitoring a single closing edge, in particular the secondary closing edge of a door.
- a presence sensor for mounting above a door frame is described.
- a transmitter and a receiver are mounted with the help of a rigid elongated carrier above the door frame.
- the angular position of transmitter and receiver can be changed by means of a swiveling attachment.
- FR 2 160 274 refers to a presence detector, in particular for a sliding door.
- a transmitter is mounted between two receivers on a mounting rail.
- a detector for detecting objects in an elevator door is in WO 82/02787 described.
- an object of the invention can be considered to provide a door monitoring sensor, which is particularly variable in use.
- the Matuschrvachungssensor of the above type according to the invention further developed in that the mounting means for mounting the transmitting unit and the receiving unit are formed on the door panel with an adjustable by an operator variable effective distance from each other.
- the first core idea of the invention can be regarded as initially accommodating the transmitting unit and the receiving unit in separate housing parts for the components accommodated in the same housing in conventional door monitoring sensors, and also for providing measures that these separate functional units can be positioned at the door leaf during the installation and the installation of the door monitoring sensor with a variable distance.
- Another core idea of the invention may be considered to provide suitable mounting means for this purpose, which allow an adjustment of the distance of the transmitting unit to the receiving unit manually by an operator.
- the door monitoring sensor according to the invention has a particularly high Triangulationsakeit, especially at high mounting heights.
- a further advantage of the invention can be seen in the fact that the door monitoring sensor according to the invention can be adapted extremely variably to virtually all occurring door widths and door heights and that this can be carried out in particular when setting up the door monitoring sensor in place by an operator.
- the door monitoring sensor according to the invention Compared to a construction in which several classical triangulation buttons are mounted next to one another, in addition to the significantly better triangulation sensitivities, the door monitoring sensor according to the invention also achieves significantly better measured data at considerably lower costs.
- Door monitoring sensors of the type described here preferably operate with infrared light.
- infrared light In principle, however, for the present description with the term light electromagnetic radiation in the visible range and adjacent areas, including ultraviolet light and in particular infrared light, are understood.
- the delivery of a control signal to a door control takes place in the door monitoring sensor according to the invention in principle based on a comparison of actual and current measurement data with previously learned values.
- the teaching of the comparison values can be carried out after the installation and the device of the door monitoring sensor on the door to be monitored. This can in particular also be largely automatic, so that the receiving unit in the monitoring area searches for specific intensity structures and these are then stored in the control and evaluation unit.
- the door monitoring sensor is then substantially sensitive to rapid changes in the reflected light as compared to the learned data, which may change slowly on a larger time scale.
- the transmitting unit has a plurality of transmitting modules and the receiving unit has a plurality of receiving modules.
- particularly broad monitoring areas can be realized. Particular preference is given to using respectively identical transmitter modules and / or identical receiver modules. It must then be kept less components.
- a transmission module is assigned to a reception module.
- a triangulation sensor is then formed by each individual pair of a transmission module and an associated reception module.
- the achievable base width and thus the achievable triangulation sensitivity can be further increased if the pairs of transmitting modules and receiving modules are nested in one another mounted on the mounting means.
- a base width of the triangulation sensor extends or base widths of the triangulation sensors extend over a width of the door leaf.
- the width of the door leaf or the entire width of the door leaf it should be understood to mean substantially the entire linear extent of the door leaf in the direction transverse to the pivot axis of the door.
- the entire door width will not be completely covered in most cases, since, for structural reasons, an area from which is sent or an area in which will be slightly offset inwards.
- housing parts of the door monitoring sensor according to the invention protrude laterally beyond the door leaf,
- embodiments are preferred in which the door monitoring sensor covers substantially the entire width of the door leaf but does not project beyond the door leaf. The freedom of movement of the door leaf thus remains guaranteed.
- a range of at least 80%, preferably greater than approximately 90%, of the linear extent of the door leaf in the direction transverse to the pivot axis of the door can be understood ,
- the transmitting unit is set up to radiate a light pattern on the floor, which extends across the width of the door panel, and the receiving unit is arranged for optically detecting the light pattern over the width of the door panel of the door to be protected.
- the DE 10 2007 025 394 A1 exploiting basically known triangulation geometry utilizing substantially a whole width of the door panel for monitoring not only the minor closing edge but a much larger surveillance area.
- a second core idea of these variants is then to modify the transmitting unit and the receiving unit so that on the one hand a light pattern is irradiated to the floor in front of the door leaf of the door to be monitored, which extends substantially over the entire width of this door leaf, and on the other hand Form receiving unit accordingly that this pattern of light over the entire width of the door panel can be detected.
- an area irradiated by a transmission module essentially has the shape of a having a right-angled triangle, wherein the hypotenuse of this right-angled triangle is formed by one of the peripheral transmit beams, and / or one of received light beams, which are detected by a receiving module, irradiated region has substantially the shape of a right triangle, wherein the hypotenuse of this right triangle is formed by a peripheral receiving light beam.
- An important advantage of this variant is to be considered that particularly broad monitoring fields or monitoring areas can be achieved, which in particular can have substantially vertical limits. In this way, in the case of a door to be monitored, both the secondary closing edge and the main closing edge can be monitored and secured with one and the same sensor.
- the variability of the distance between the transmitting unit and the receiving unit can in principle be achieved in that the mounting means are displaceable even relative to the door leaf, in particular manually displaceable. According to the invention, however, the mounting means are firmly positioned on the door leaf and then arranged the transmitting unit and / or the receiving unit or at least essential components of these components on the mounting means displaceable.
- the mounting means may be a common mounting profile with which the transmitting unit and the receiving unit, in particular, the transmitting modules and the receiving modules, are mounted on the door leaf.
- the transmitting unit can also have only a single separate transmitting module, and likewise the receiving unit can have only one receiving module.
- the outer limits of the surveillance area are then formed by transmitted light beams and not by received light beams.
- At least one transmitter module and / or at least one receiver module has means for pivotable mounting.

- a visible, so in the visible range emitting, light source may be present. This light source may be appropriate relative to the other components the transmitting module and / or the receiving module to be aligned so that it illuminates to an outer edge of the area detected by the transmitting module or the receiving module.
- a semiconductor laser can be used for this purpose.
- the light pattern according to the invention to be radiated onto the floor in front of the door to be monitored can fundamentally be of any arbitrary nature.
- it may be a plurality of light spots.
- at least one transmission module has a plurality of individual light transmitters.
- At least one transmission module have a diffractive optic and / or a partially opaque mask.
- the receiving unit In order to effect optical detection of the light pattern over the entire width of the door leaf of the door to be secured, it is necessary for the receiving unit to detect the light pattern in the monitoring area, in any case with a specific location triggering.
- the receiving unit can have at least one detector with a plurality of receiving elements and / or at least one position-sensitive detector (PSD).
- PSD position-sensitive detector
- an opening sensor for determining a degree of the door opening may expediently be present.
- This sensor can basically also be connected to the common bus system of the door monitoring sensor.
- FIG. 1 An embodiment of a door monitoring sensor 100 according to the invention will be described with reference to FIG. 1 explained in more detail. Equivalent components are given the same reference numerals in all figures.
- the in Fig. 1 illustrated door monitoring sensor 100 according to the invention a transmitting unit 20, a receiving unit 50 and a control and monitoring unit 70.
- a mounting profile 62 is provided in the illustrated embodiment, which may be, for example, an aluminum extruded profile.
- the transmitting unit 20, the receiving unit 50 and the control and evaluation unit 70 are mounted in an upper region of a door leaf 12 of an automatic revolving door 10 to be monitored.
- the automatic door 10 can be opened and closed by means of an actuating arm 82 which is driven by a door control 80 become.
- the door leaf 12 is pivoted in the schematically indicated door pivot 16.
- a door handle 18 and a door frame 14 are shown schematically.
- the door control 80 is operatively connected to the door monitoring sensor 100 according to the invention, that is to say that the door control 80 only pivots the door leaf 12 via the actuating arm 82 when the door monitoring sensor 100 according to the invention allows it, ie does not detect a critical object.
- the transmission unit 20 radiates light 22 into a surveillance area 40 on the floor 44 in front of the door leaf 12.
- a light pattern 30 is thereby formed, which in the example shown consists of a total of eight substantially equidistantly positioned light spots or spots 31, ,
- the transmitting unit 20, the receiving unit 50 and the control and evaluation unit 70 are interconnected via a schematically indicated bus system 72.
- This may be, for example, a flexible connection via a cable, which is laid in the mounting profile 62 and via which the transmitting unit 20, the receiving unit 50 and the control and evaluation unit 70 are on the one hand supplied with power and on the other hand signals, in particular control , Configuration and / or measurement signals, can replace.
- the transmitting unit 20 has a single transmitting module, which is not shown in more detail, and the receiving unit 50 has a single receiving module (not shown in more detail).
- the base width which substantially corresponds to a width of the door panel 12, that is, substantially the linear extent of the door panel 12 in a direction transverse to the pivot axis of the door, may typically be about 75 cm to 135 cm.
- the mounting height of the door monitoring sensor 100 according to the invention may typically be about 1.5 m to 3 m.
- a particular advantage of the door monitoring sensor 100 according to the invention is that even larger field widths, ie larger widths of the monitoring area 40 can be achieved by mounting several door modules and / or multiple receiver modules on the door leaf 12. These can be, in particular, identically constructed transmitting and receiving modules which also interleave can be mounted. As a result, extremely wide monitoring fields can be covered without detection gaps with virtually maximum achievable base width.
- the plurality of transmitter modules and receiver modules may be mounted in the mounting profile 62.
- an assignment of the respective modules can take place automatically or at least semi-automatically via the bus system.
- the receiving unit 50 thus remembers the positions of the light spots 31, .., 38 on the floor 44. If now an object is immersed in this light curtain, one or more light spots 31, .., 38 are detected at an altered position by the receiving unit 50 , In particular, these position changes of the detection signals in the receiving unit 50 can represent a detection criterion.
- Fig. 1 two main advantages of the door monitoring sensor 100 according to the invention are shown.
- the door monitoring sensor 100 according to the invention allows a particularly flexible adaptation to a respective existing door width.
- the largely maximized base width of the triangulation sensor also achieves an as far as maximized detection sensitivity or triangulation sensitivity.
- Fig. 2 shows an embodiment of a transmitting unit 20 with a first transmitting module 24, which emits transmitted light 21, and a second transmitting module 26, which emits transmitted light 23.
- the transmitter modules 24, 26 are mounted on the mounting profile 62 and a connection cable 78 and a connector 74th connected to the common bus system 72.
- the transmitter module 26 pivotally designed, which is shown schematically by a double arrow 25.
- a marking system in the form of a laser module 64 is present, which is rigidly coupled to the transmitter module 26.
- the laser module 64 emits visible light 65 and marks, for example, the edge of a region detected by the transmitter module 26 and thus the field width and the angle of inclination of the transmitter module 26. With the aid of this laser module 64, the assembly and alignment of the transmitter module 26 can be simplified and facilitated.
- all transmission modules which can also be referred to as optical projection systems, can be made pivotable and provided with a marking system.
- the transmitter modules 24 and 26 each have a plurality of transmission chips 27 as light transmitters. With the aid of lenses 28, 29, light 21, 23 emitted by the transmission chips 27 is radiated in the direction of the monitoring area 40.
- a detection range for the door monitoring sensor 100 according to the invention can be adjusted.
- Fig. 4 is shown using the example of a double transmitter projection system, how to create a row of light spots on the floor with several transmission chips 27 and the associated simple lens systems.
- the focal length of the lenses 28, 29 may be for example 24 mm.
- the light spots on the floor can basically be shaped and changed in their image form by using transmission chips with special geometry.
- embodiments are particularly preferred in which two commercially available rectangular transmitting chips, which may for example have a size of 0.4 x 0.4 mm 2 , are mounted side by side in order to achieve an elongated image on the floor.
- the transmission chips arranged next to one another are then preferably connected in series.
- FIGS Figures 3 and 5 An embodiment of a receiving unit 50 will be described with reference to FIGS Figures 3 and 5 explained in more detail.
- a first receiving module 54 which receives light 51
- a second receiving module 56 which receives light 53.
- the receiving modules 54, 56 are mounted on the mounting profile 62 and connected via a connecting cable 78 and a connector 76 to the common bus system.
- Very large monitoring fields require very wide-angle optical systems on the transmitting and receiving side.
- the systems can be divided into several optical subsystems both on the transmitting and on the receiving side, so that the Weitwinkltechnik avoided and in a simple and inexpensive way good and low-defect optical images are possible.
- the receiving modules 54, 56 are rigidly attached to the mounting profile 62. In principle, however, pivotable and / or linearly displaceable receiving modules can also be provided here.
- the receiving unit 50 off Fig. 3 Details of the receiving unit 50 off Fig. 3 are in Fig. 5 shown.
- the light 51, 53 is guided by means of lenses 58, 59 on a plurality of photodiodes 57.
- photodiodes 57 which may also be referred to as photodiode arrays, a position-sensitive photodetector is provided in each case.
- the focal length of the lenses 58, 59 may typically be about 19 mm.
- position sensitive detectors, PSDs, or CCD lines can be used.
- Triangulation sensors are generally constructed in such a way that the relative position of the transmitting and receiving optics is determined exactly and with long-term stability.
- the transmitting unit 20 and the receiving unit 50 are arranged separately from one another. In principle, this results in higher adjustment requirements, so that it is expedient to provide suitable aids for this, such as, for example, the laser module 64 described above.
- Possible torsional movements of the mounting profile after assembly may also play a role.
- two or more receiving and / or transmitting lenses can be used.
- Scanning range changes due to temperature fluctuations are generally not critical, since such changes are slow and therefore can be tracked electronically.
- the Pepita bin can occur when the door monitoring sensor is directed to a visually textured floor. In particular, this effect occurs when very high-contrast colors, such as black and white, are present in the region of the boundary of a light spot. On the whole, this can lead to faulty circuits, and in the learning phase it can happen that the door monitoring sensor is set to the wrong level in the case of such floors. In a detection mode, such trays can then simulate a detection object.
- the Pepita bin can basically be reduced or avoided if the transmitter images, so for example, the light spots are very narrow. Although such narrow transmission images can be generated by dimming the transmit chips, but this leads to an undesirable and adverse loss of light.
- transmission lenses with increased focal length can be used. So that one does not suffer any loss of light due to the higher focal length, the lens area can be correspondingly increased, if the space available permits it.
- Pepita cement can be effectively combated and reduced by particularly large distances between transmitting and receiving unit, which are achieved especially in the door monitoring sensor according to the invention in an advantageous manner.
- FIGS. 6 and 7 Further arrangement examples for transmitting modules and receiving modules are in FIGS. 6 and 7 shown.
- Fig. 6 shows an embodiment with two transmission modules S1, S2, which are arranged on the outside of the door leaf and two internally arranged receiving modules E2, E1.
- the transmitting module S1 and the receiving module E1 a first and by the transmitting module S2 and the receiving module E2, a second triangulation is formed.
- the transmitter modules and receiver modules are arranged interleaved, so that the entire width of the door panel can be covered by the base widths of these triangulation sensors.
- FIG. 7 A further development with interleaved transmitting modules and receiving modules is in Fig. 7 shown.
- Fig. 7 Here are a total of four triangulation sensors with four transmission modules S1, .., S4 and four receiving modules E1, .., E4 present, which are each arranged nested.
- the present invention provides a novel mechanically and optically modified triangulation sensor as a door monitoring sensor.
- the usual structure of a triangulation sensor was modified in such a way that it separates the usually associated components transmitter unit and receiver unit.
- the separate units allow a largely maximum mounting distance and thus a largely maximum Triangulationsakeit.
- This variability in the mounting arrangement of transmitting unit and receiving unit enables particularly wide monitoring fields and vertical monitoring field boundaries.
- the transmitting unit has a plurality of transmitting modules, so that a wide and dense monitoring field can be achieved. Accordingly, adapted receiving modules are provided.
- For professional installation of the door monitoring sensor according to the invention also aids and simplifications are proposed.
