Definitions

  • the invention relates to a knob cylinder with a sensor device for rotary knobs of electronic or electromechanical knob cylinders.
  • Electronics or elements of rotary knobs of knob cylinders are known to be used to control an actuator accommodated in an associated profile cylinder of a wing lock when actuated, to connect a lock bit of the profile cylinder to the rotary knob in a rotationally effective manner.
  • the actuator is switched off.
  • the actuation typically takes place in a contactless manner, for example by means of a code card, for example in the form of a transponder card, which is placed on a reader of the rotary knob or is approached to it and contains authorization data. This data is read out by the reader and checked for authorization to open the respective leaf. If the test is successful, the actuator is activated or energized and the sash can be unlocked and opened using the rotary knob.
  • Rotary knobs offer very little space, so that incremental encoders can hardly be used to save space.
  • slotted disks have the disadvantage that they can become dirty, which can impair operational safety.
  • Last but not least, a relatively complex data evaluation is necessary in order to determine the direction of rotation of the slotted disc.
  • the object of the invention is to at least reduce the disadvantages of the prior art.
  • a knob cylinder according to the invention comprises a sensor device.
  • the sensor device according to the invention is designed to be inserted with one part into a rotary knob of a knob cylinder. It has at least a pair of sensors and a counter element.
  • This counter element and the at least one pair of sensors are arranged such that they can be moved relative to one another along a substantially circular movement path, for example via a transmission.
  • the counter element or the respective pair of sensors can be arranged in a stationary manner, while the respective pair of sensors or the counter element is accordingly moved along the circular movement path, that is to say along a respective circular line.
  • the counter element and the sensors are opposite one another in such a way that the detection areas of the sensors each enclose a partial area of the movement path and partially overlap one another in the area of the movement path. I.e. each sensor detects a specific area of the movement path, the two areas thus sharing a partial area.
  • the movement path runs partially outside the detection areas of the at least one pair of sensors. I.e. the detection areas of both sensors do not cover the entire movement path.
  • the counter-element "moves" one after the other through the detection areas of the at least one pair of sensors.
  • the counter-element first comes into the partial detection area of only one sensor, then into the overlapping area of both sensors, then into the detection partial area now the other sensor, and then into an area that is not detected by any of the sensors. This makes it possible to determine in which direction the movement is taking place. In addition, a back and forth movement can be detected, and that with simple, space-consuming means. Due to the formation of several sensor detection areas, the counter-element does not have to have any filigree structures such as a slotted disc for the sensor to function.
  • the sensors are preferably formed by means of GMR sensors.
  • the counter element is magnetized or, for example, electrically magnetized. This offers the possibility of simply being able to use the electrical resistance of the sensors as a measured variable.
  • the relative movement of the counter element to the sensors causes relatively large changes in the electrical resistance of the sensors, which enables a simple evaluation circuit.
  • the sensor device preferably also has such an evaluation circuit.
  • the evaluation circuit is set up to detect, on the basis of sensor signals that are output by the at least one pair of sensors, that the counter-element is moving past each sensor. This makes it possible to determine in which detection sub-area the counter-element is located or whether it is located outside the detection areas.
  • the evaluation circuit preferably detects the movement past by XORing the sensor signals with one another. I.e. the evaluation circuit always detects when a detection sub-area is "entered” or left by the further counter-element. This is a particularly simple and inexpensive solution.
  • the passing is preferably detected in that the evaluation circuit delays a signal formed by means of the XOR linkage of the sensor signals by a predetermined value as a delay signal and XOR links the signal formed with the delay signal.
  • the evaluation circuit delays a signal formed by means of the XOR linkage of the sensor signals by a predetermined value as a delay signal and XOR links the signal formed with the delay signal.
  • a rotary knob according to the invention is arranged to be freely rotatable with respect to a lock bit of a profile cylinder. It can also be operated to energize an actuator, which then connects the rotary knob with the lock bit in a rotationally effective manner, so that the rotary knob moves the lock bit with it when it is turned.
  • the rotary knob has a reader which is set up to read data from an access data carrier such as a code card.
  • the rotary knob also has a part of one of the sensor devices described above. I.e. apart from the sensor device, the rotary knob remains almost untouched.
  • the actuator can be, for example, a motor or a lifting magnet which is coupled to a coupling mechanism which, when the actuator is energized, is actuated in such a way that the aforementioned rotational connection is established.
  • the reader is preferably connected in an active mode so that it is able to read data from an access data carrier. In an inactive state, however, the reader is switched off so that it is no longer able to read data from an access data carrier, such as a code card, a person with biometric data or memorized access codes (mental features) as access data. In inactive mode, the reader consumes little or no energy.
  • the sensor device comprises according to the invention the aforementioned evaluation circuit. This is set up to trigger a connection of the reading device when the evaluation circuit has detected the counter-element moving past one of the sensors. I.e. the sensor device can fulfill two tasks, on the one hand the detection of the direction of movement and on the other hand simply only the detection of the rotary movement at all, and that without complex logic.
  • the evaluation circuit preferably comprises an XOR (exclusive OR) element to which the sensor signals are input and whose output signal is input to the reader or to a controller that controls the reader.
  • XOR exclusive OR
  • the evaluation circuit preferably also has a time delay element to which the output signal of the aforementioned, an XOR element is input. It also has another XOR element, to which the output signal of one XOR element and an output signal formed by the delay element are input. The output signal of this other XOR element is in turn input to the reader or the controller.
  • the aforementioned counter-element or the at least one pair of sensors is preferably arranged in a stationary manner, that is to say is preferably not moved with respect to the entire rotary knob.
  • the counter element or this pair of sensors is attached to the profile cylinder or integrated into it. Accordingly, this pair of sensors or the counter-element is arranged to be moved along the path of movement by the rotary knob when the rotary knob is turned.
  • Figure 1 shows a knob cylinder 100 as part of a lockable wing lock in two views, namely only the parts relevant to the invention.
  • the knob cylinder 100 comprises a profile cylinder 110 with a freely rotatable lock bit 111 and a faceplate hole 112.
  • a rotary knob 120 is attached to one end of the profile cylinder 110.
  • This is provided with a reader 121, which is coupled to an antenna 122 for contactless contact with an access data carrier (not shown).
  • a preferably optical display 124 is embodied, for example, in the form of an illuminated ring.
  • a self-sufficient energy supply in the form of a battery 123 or an accumulator is accommodated in the rotary knob 120.
  • the rotary knob 120 has four sensors 125, preferably in the form of GMR sensors, on its side facing the profile cylinder 110.
  • the sensors 125 are arranged in such a way that the detection areas 126 of the individual sensors 125, represented with the aid of the hatched areas, partially overlap one another in pairs, indicated by the cross-hatched areas.
  • the profile cylinder 110 has on its side facing the rotary knob 120 elements that can be detected by the sensors 125, here in the form of two magnets 113.
  • the sensors 125 follow a respective, advantageously the same, circular path, the center of which is the axis of rotation of the rotary knob. This leads to the detection areas 126 of the individual sensors 125 being alternately moved past one of the magnets 113. This makes it possible for the respective sensor 125 to detect when the respective magnet 113 enters the associated detection area 126 or leaves it. Based on this, each sensor 125 outputs a corresponding signal.
  • the signals preferably from all sensors 125, but at least from sensors 125 belonging to a pair, that is to say two sensors with partially overlapping detection areas 126, are transmitted to a data processing logic, for example a processor.
  • the sensor signals are or are preferably digitized.
  • a sensor signal S1 is assigned to the left sensor 125 for the upper pair of sensors 125, while a sensor signal S2 is assigned to the right sensor 125.
  • Figure 2c shows the case when the rotary knob 120 is not continuously rotated in one direction. Instead, the rotary knob 120 is turned back again shortly after leaving the detection area 126 of the sensor 125 associated with the signal S1, so that it enters the detection area 126 of this sensor 125 again without having previously entered the detection area 126 of the sensor 125 associated with the signal S2. And this is clearly reflected in the resulting signal curves.
  • the clear signal curves can be used to easily determine whether the rotary knob 120 is turned in the direction of unlocking or locking the wing lock, not shown, and thus the connected wing should be unlocked or locked.
  • the number of turns of the rotary knob can also be used as a basis. For example, if the check of the access data was successful, it can be provided that a user must turn the rotary knob twice in the unlocking direction before the rotary knob releases the active rotational connection again.
  • Figure 3 shows an extension of the knob cylinder 100.
  • the sensor signals S1, S2 are input to an XOR element or gate 101. Its output signal A is input to a controller 102 here.
  • the controller 102 functions, for example, in such a way that, when the signal A assumes the high level and the rotary knob 120 is not activated, it activates the reader 121 either immediately or after a predetermined number of high level phases in the output signal A have been exceeded, i.e. switches on or on. I.e. a person who wants to open a door, for example, can activate the reader 121 by simply turning the rotary knob 120.
  • the display 124 is preferably activated such that it lights up yellow, for example, in order to indicate readiness for reading.
  • Figure 3b shows the curves of the output signal A in relation to the in Figure 2 shown curves of the sensor signals S1, S2.
  • the controller 102 can recognize when the magnet 113 "enters” or leaves a respective detection (partial) area 126.
  • Figure 4 shows an extension to the in Figure 3a shown arrangement.
  • a delay element 103 formed here by means of a dead time element
  • a second XOR element 101 are connected in series between the XOR element 101 and the controller 102.
  • the second XOR element 101 receives a signal V which corresponds to the output signal A, except that its course is shifted by a predetermined time period ⁇ t by means of the delay element 103.
  • the output signal S of the second XOR element 101 resulting therefrom is now input as a signal S to the controller 102.
  • the delayed signal V connected to the second XOR element 101 serves the purpose of converting a signal A with relatively long high-level phases into a signal S with relatively short high-level phases. I.e. signals with very short high level pulses can be input to the controller 102.
  • the time duration ⁇ t is determined in such a way that the downstream controller 102 can continue to reliably detect each pulse with the minimum pulse width.
  • Figure 4b shows the course of the signals S1, S2, A, V, S for the course of the signals S1, S2 according to FIG Figure 2a .
  • the time delay ⁇ t between the signals A, V can also be clearly seen here.
  • the display 124 has, for example, a multicolored lighting device, for example in the form of an RGB LED. This does not light up when the signals S1, S2 are both low. If S1 changes its state to high, the LED lights up red. If the other signal S2 also goes high, the LED lights up blue. If the signal S1 loses the high level (again), the LED lights up green.
  • a multicolored lighting device for example in the form of an RGB LED. This does not light up when the signals S1, S2 are both low. If S1 changes its state to high, the LED lights up red. If the other signal S2 also goes high, the LED lights up blue. If the signal S1 loses the high level (again), the LED lights up green.
  • an acoustic display can also be provided, from which a special acoustic signal can be output for each state of the sensor signals S1, S2.
  • only one sensor 125 can be activated in order to activate the reader 121.
  • the sensors 125 can also be activated in the active mode in order, for example, to be able to carry out evaluations of the frequency of visits and the like when the rotary knob 120 is permanently activated.
  • the rotary knob 120 is activated, it is preferably provided that the sensors 125 are left activated. This makes it possible to correspondingly lengthen the activation time of the rotary knob 120 by turning the rotary knob 120. Furthermore, it can be provided that the sash is unlocked when it has been detected that the rotary knob 120 has completed a certain number of revolutions (for example: 2).
  • the rotary knob 120 and preferably also the sensors 125 are switched off for a predetermined time.
  • the number of pairs of sensors 125 is not limited.
  • three sensors 125 can be arranged whose detection areas 126 partially overlap one another in pairs. Overall, the three detection areas 126 can even cover the entire movement path, just not the detection areas 126 that overlap in pairs.
  • the number of magnets 113 is not limited either.
  • the respective magnet 113 can be designed as a permanent magnet or as an electromagnet.
  • the sensors 125 can also be optical, haptic, sound-based or other types.
  • the magnet 113 is realized by a counterpart belonging to the sensor 125 for sensor actuation.
  • the sensors 125 and magnets 113 can be interchanged with one another.
  • the sensors 125 can additionally or alternatively serve to wake up or activate the reader 20. I.e. the user must first turn the rotary knob 120 before an access data carrier can even be read out.
  • Special operating modes such as emergency opening can also be implemented in that the rotary knob 120 has to be turned in a certain way, for example, which can be easily recognized with the sensor device according to the invention.
  • the invention offers an extremely simply structured and space-saving solution for detecting rotary motion, preferably of the rotary knob 120 of a knob cylinder 100.
