Definitions
- the invention relates to an electronically activatable Locking mechanism for a locking device with a Antenna for receiving signals from a transponder of a Data carrier and for the production of electrical, the Transponder corresponding signals, with control electronics for evaluating the signals of the antenna and the Control of a locking bolt depending on the Data of the transponder and with a signal detection device for detecting the signal of the antenna and with a data acquisition device for detection and evaluation the data signals of the transponder.
- Such locking mechanisms for example, in so-called electronic locking cylinders or locking systems used for motor vehicles.
- the transponder and the data carrier serve as proof of a person for Authorization of the activation of the locking mechanism. is the transponder is in the reception area of the antenna, the data carrier is read out and from the control electronics the authorization to activate the locking mechanism determined.
- a constant readiness of the control electronics but has the disadvantage of very high power consumption.
- a high power consumption leads in particular in battery-operated locking devices, such as electronic Locking cylinders, for a short life the battery and thus a high maintenance of the Locking mechanism.
- the control electronics a capacitive Sensor upstream.
- the capacitive sensor activates the locking mechanism the control electronics. Subsequently, the data query started.
- the capacitive sensor causes a very high structural design of the locking mechanism.
- the sensor activates the control electronics any approach of a person, an animal and, where appropriate a piece of metal or in the rain, resulting in a high power consumption leads.
- the invention is based on the problem, a locking mechanism of the type mentioned at the beginning, that he has the lowest possible power consumption and a high structural complexity is largely avoided.
- the signal detection device and the data acquisition device independently activatable modules have that the assemblies connected together are and that the assembly of the data acquisition device is inactive in the ground state and by a signal of Signal detection device is activated.
- the signal detection device By this design must in the ground state exclusively the signal detection device be cyclically active. Since the signal detection means no detection of Data signals of the transponder operates requires this a particularly low power requirement.
- the signal detection device According to the invention, whether at all a transponder is located near the antenna. Only when any transponder is detected does the data acquisition device become started, the data from the disk read out and the authorization to control the locking mechanism detected. Furthermore, the required Locking mechanism according to the invention no further sensors to start the data acquisition device, since the data acquisition device from the signals of the transponder receiving signal detection device is activated.
- the locking mechanism according to the invention is therefore particularly simple and has a low power consumption on.
- the antenna could receive the data of the transponder are permanently energized.
- a constant Reception readiness of the antenna can be according to a advantageous embodiment of the invention, however, simple avoid if the signal detection device a pulse generator and a first, for the duration of a pulse has controllable switching stage and if the first Switching the antenna during the pulse with a Power source connects. This contributes to the further reduction the power consumption of the control electronics.
- the data acquisition device can be upon receipt of a Signals through the antenna according to another advantageous Simply activate the invention, if the data acquisition device a third Switching stage to its activation and if the third Switching stage of the signal detection device controlled is. In the absence of a signal the antenna remains frozen the data acquisition device in the inactive state and therefore avoids unnecessary power consumption during standby without signal of the antenna.
- the detection of the transponder requires according to another advantageous development of the invention a particularly low power consumption when the second Switching stage remains in the active state up to 100 ⁇ s.
- Locking mechanism helps when a data collection device connected to the third switching stage is.
- the detection by the signal detection device if there is a signal needed much less electrical energy than the detection, what data is available.
- the arrangement of the data acquisition device exclusively after the third Switching can be the power consumption for the data acquisition device keep it low.
- the locking mechanism according to the invention is particularly compact constructed when the signal detection device and the data acquisition device a common microprocessor exhibit.
- the fourth switching stage is easy to control when the Data acquisition device, the signals of the transponder has evaluated and releases the locking mechanism. Without Release authorization is omitted under the control of fourth switching stage, so that the locking latch de-energized in his blocking the lock cylinder position remains.
- Figure 1 shows schematically a sectional view through a lock cylinder 1 with a in a housing. 2 rotatable core 3 and an electronically activated Locking mechanism 4 for selective blocking or release the movement of the core 3.
- the locking mechanism 4 has an electronic control unit 6 connected to an actuator 5.
- the actuator 5 serves to hold or release the movement one biased into a recess 7 of the core 3 Locking bar 8.
- the control electronics 6 is equipped with an antenna 9 and connected by a battery 10 as Power source supplied with electrical power.
- the core 3 has a closing channel 11 for receiving a shank of a key 12.
- the key 12 has one with a transponder 13 connected to the disk 14. Is the Key 12 moves in the vicinity of the antenna 9 receives these signals of the transponder 13.
- the control electronics. 6 reads out the data carrier 14 and determines from this data a locking authorization of the lock cylinder 1. Thus will depend on the data of the disk 14, the actuator 5 selectively driven or the control omitted.
- FIG. 2 shows a circuit diagram of the locking mechanism 4 Figure 1 with the disk 14 and the transponder resonant circuit 13 of the key.
- the control electronics 6 has a signal detection means 15 for receiving the Signals of the antenna 9 and a data acquisition device 16 for reading the data carrier 14 and for determination the closing authorization.
- the signal detection device 15 and the data acquisition device 16 have a common Microprocessor 17 and independently activatable modules.
- An assembly of the signal detection device 15 has a pulse generator 18 and a first switching stage 19. Depending on the signals the pulse generator 18, the first switching stage 19 is driven and the antenna 9 is connected to the battery 10. As a result, in the antenna 9, a magnetic pulse educated.
- the antenna 9 is found in the Antenna 9 Reactions due to the magnetic pulse.
- the battery 10 With the Amplifier 21 connected. This will be the repercussions detected in the antenna 9 and the microprocessor 17 for Signal evaluation forwarded.
- the microprocessor 17 detects the existing in the reception area of the antenna 9 Transponder 13 and then activates the third Switching stage 25, thus connecting the data acquisition device 16 with the battery 10.
- a carrier generator 28 the antenna 9 is energized periodically.
- the antenna 9 transmits thereby a magnetic alternating field, which the transponder 13 is powered in their reception area, and the Transponder 13 then sends its data. These be from the signal of the antenna from a demodulator 26 and an amplifier 27 detected and sent to the microprocessor 17 forwarded for evaluation.
- the microprocessor 17 is connected to a fourth switching stage 22, which activates the actuator 5 shown in FIG.
- the antenna 9 receives in response to the signals the pulse generator 18, the first switching stage a periodic Excitation pulse. This turns the winding of the antenna 9 energized. It forms near the antenna magnetic field, which due to the shortness of the pulse collapses again. After the impulse arises in the antenna 9 no periodic voltage change as Feedback by the impulse, which has the consequence that the third switching stage 25 is not driven and the data acquisition is not turned on.
- the impulsive excitation of the resonant circuit in the transponder 13 after the impulse there is an evanescent, periodic one Oscillation according to the resonance characteristic of the antenna circuit one.
- a transponder antenna 24 generates in rhythm the vibration is a relatively weak magnetic Field.
- the antenna 9 receives the field and gives it as AC signal to the amplifier 21 of the signal detection device 15 continue.
- the microprocessor 17 controls after evaluation of the pulse train, the third Switching stage 25 for the data acquisition device 16 at.
