Please refer to Figures 1 to 3. Figure 1 is the first block diagram of the non-contact graphic door lock of this creation; Figure 2 is the schematic diagram of the non-contact graphic door lock of the creation; Figure 3 is the diagram A schematic diagram of the sensing unit of the non-contact graphic door lock of the present invention. As shown, the non-contact graphic door lock 10 of the present invention comprises a plurality of sensing units 12, a processing module 13 and an electromagnetic lock 14, which can be arranged in a building door or other place to be locked, such as a safe.

The plurality of sensing units 12 are arranged on the substrate 11. The substrate 11 serves as a base of the plurality of sensing units 12, and may be embedded in the wall beside the electromagnetic lock 14 during installation, or may be additionally installed. In the vicinity of the electromagnetic lock 14.

Each sensing unit 12 can sense an object within a predetermined distance thereof and correspondingly generate an inductive signal, that is, the sensing unit 12 has a fixed effective sensing distance, and the effective sensing distance can be set to a predetermined distance, only when an object (for example, When the hand or finger is close to the sensing unit 12 within a predetermined distance, the sensing unit 12 senses it, and does not generate an induction when an object passes farther, causing a false positive. Moreover, after sensing the object, the sensing unit 12 generates a corresponding sensing signal.

The processing module 13 receives the plurality of sensing signals generated by the plurality of sensing units 12, and determines the sensing order of the plurality of sensing units 12 according to the sensing unit 12 corresponding to each sensing signal. In more detail, the processing module 13 can determine which sensing unit 12 the sensing signals are generated by, that is, which sensing unit 12 senses the object, and the processing module 13 can also determine the plural number. The sensing unit 12 senses the order of the objects.

Here, as shown in FIG. 2, the arrangement of the plurality of sensing units 1, 2, 3, 4, 5, 6, 7, 8, and 9 on the substrate 11 will be explained by taking a 3×3 configuration as an example, but It can also be other configurations such as 3×4 or 4×3, depending on its needs, and should not be limited to this. As shown in the figure, there are nine sensing units from the sensing unit 1 to the sensing unit 9, and the processing module 13 can determine which sensing unit is sent from the sensing unit when receiving the respective sensing signals.

Therefore, for example, if the user approaches the sensor sequentially, and passes through the sensing units 1, 4, 7, 8, and 9 (as shown in FIG. 2, the connection shape will be similar to the English letter L), then the processing mode The group 13 receives the sensing signals of the plurality of sensing units, and discriminates therefrom that the sensing units 1, 4, 7, 8, and 9 are triggered to generate the sensing signals, and the order is regarded as a group of sensing sequences. . In addition, the processing module 13 can set the time range of sensing. That is to say, for example, the order of the received inductive signals received within five seconds is judged as a set of sensing sequences. Or, when no other inductive signals are received within one second after receiving an inductive signal, the inductive signals received in front of them are regarded as a set of sensing sequences.

In addition, the non-contact graphic door lock 10 of the present invention may have a preset sequence built in the processing module 13, or a set of preset sequences may be set by the setting unit 15, and the preset sequence may be transmitted to the processing module 13. The processing module 13 stores the settings of the preset order. Then, when the processing module 13 determines that a set of sensing sequences is received, it compares whether the sensing sequence matches the preset order set by the setting unit 15. If the sensing sequence matches the preset order, the processing module 13 An open signal will be generated, and the electromagnetic lock 14 will receive the open signal and unlock accordingly. When the processing module 13 determines that the sensing order is different from the preset order, there is no further action.

Furthermore, each of the sensing units 12 may include an infrared emitting element 121, an infrared receiving element 122, and an inductive indicator light 123, respectively, which may be disposed in a translucent or transparent cover through which infrared rays may pass. The infrared ray emitting element 121 emits infrared rays having an effective distance of the predetermined distance described above, or it should be said that the predetermined distance of the sensing unit 12 is determined according to the effective distance of the infrared ray emitted from the infrared ray emitting element 121.

When the object is close to the infrared emitting element 121 within a predetermined distance, the object reflects infrared rays, and when the infrared receiving element 122 receives the reflected infrared light, an inductive signal is generated, that is, the above-mentioned sensing signal is It is generated after the infrared receiving element 122 receives the reflected infrared rays. In addition, the generated sensing signal is not only transmitted to the processing module 13 as described above, but also transmitted to the sensing indicator 123. After receiving the sensing signal, the sensing indicator 123 generates an induction signal according to the sensing signal. The user can know whether he or she actually senses the sensing unit 12 by sensing whether the indicator light 123 is illuminated or not, so that the unlocking action is smoother.

Continue to refer to Figure 4, which is the second block diagram of the non-contact graphic door lock of this creation. As shown, the non-contact graphic door lock 10 of the present invention can be connected to the remote device 21, and the remote device 21 can be a device that can receive signals by wire or wirelessly or can transmit an open signal, such as a mobile phone, a tablet computer, or a blue device. Bud devices, notebook computers or desktop computers, and the wireless connection method can be Internet, infrared or Bluetooth, but the above is only an example and should not be limited. The remote device 21 can receive the activation signal generated by the processing module 13 when determining that the sensing sequence is the same as the preset sequence, and corresponding to the activation signal generating notification message.

In other words, when the person successfully opens the electromagnetic lock 14 by sensing the plurality of sensing units 12 in sequence, the processing module 13 can simultaneously transmit the opening signal for opening the electromagnetic lock 14 to the remote device 21, and the remote device 21 A notification message can be generated to inform the user that the non-contact graphic door lock 10 of the present creation has been opened. For example, when a person who knows the preset order is in a state in which the non-contact graphic door lock 10 of the present creation is not opened, the electromagnetic lock 14 is turned on, and at this time, the user can receive the electromagnetic lock 14 by, for example, a mobile phone. The message that has been opened is alerted and the corresponding processing is performed.

Conversely, the remote device 21 can generate a control signal to the processing module 13, and the processing module 13 generates an activation signal to the electromagnetic lock 14 corresponding to the control signal, so that the electromagnetic lock 14 is unlocked, that is, can be preset and processed. The distal device 21 to which the module 13 is connected allows the user to unlock the electromagnetic lock 14 from a remote device 21 that can be coupled to the processing module 13.

Moreover, the remote device 21 can also set a preset sequence and transmit a preset sequence to the processing module 13, that is, the user can use the remote device 21 connected to the processing module 13 to preset the processing module 13. Change in order.

The processing module 13 generates an enable signal to unlock the electromagnetic lock 14 when the sensing sequence is determined to be the same as the preset sequence. In addition, when the sensing sequence of the sensing plurality of sensing units 12 is different from the preset order, the number of times is greater than the number of attempts. The warning signal is generated to the plurality of sensing units 12, and the plurality of sensing units 12 stop sensing according to the warning signal.

That is to say, the processing module 13 can first set the number of attempts. When someone tries to open the electromagnetic lock 14, the plurality of sensing units 12 are sensed multiple times in succession but cannot be unlocked smoothly, and the number of errors reaches a preset number of attempts. The processing module 13 transmits a warning signal to the plurality of sensing units 12 to stop the sensing, so that the user cannot continue to try to sense the unlocking. This function can be set to automatically restore the sensing function after a certain period of time.

Moreover, the processing module 13 can also be connected to the remote device 21 as described above. The remote device 21 can receive the warning signal in addition to receiving the activation signal and generating a notification message, and can also receive the warning signal corresponding to the warning signal. The notification message warns the user that the user has attempted to unlock the non-contact graphic door lock 10 of the creation multiple times but fails, and the user can perform corresponding processing.

In addition, the non-contact graphic door lock 10 of the present invention may further comprise a sounding unit 16, which is connected to the processing module 13 and receives the warning signal generated in the above situation, and the sounding unit 16 generates and generates the warning signal according to the warning signal. Warning sounds, the warning sounds reach the role of deterrence, and can also alert people nearby to attempt to open the electromagnetic lock 14 unsuccessful.

Continued See Figure 5, which is a third-party block diagram of the non-contact graphic door lock of this creation. As shown in the figure, the processing module 13 can be further connected to the protection control system 22, and the protection control system 22 receives the activation signal generated by the processing module 13 and correspondingly releases the protection. For example, the protection control system 22 can be a residential overall anti-theft system, that is, in addition to the door lock, the anti-theft device of the window, the anti-theft device of the monitor or the garage, etc., when sensing the sensing sequence and preset generated by the plurality of sensing units 12 When the sequence is consistent, not only the electromagnetic lock 14 but also the opening signal can be transmitted to the protection control system 22 by the processing module 13, so that the devices belonging to the system are unprotected together, thus making the non-contact graphic door lock of the creation. 10 has a wider range of applications.

In addition, it is worth mentioning that the non-contact graphic door lock 10 of the present invention can also open the electromagnetic lock 14 by means of the traditional physical contact, in addition to opening the electromagnetic lock 14 by means of the above-mentioned induction, for example, opening with a key. In case of a situation such as power outages, it is necessary to meet the needs of the time.

The non-contact graphic door lock of the present invention utilizes the setting of a plurality of sensing units 12, so that the user can make a specific order of sensing from a distance thereof, and the processing module determines whether the sensing sequence is in a preset order. The electromagnetic lock is matched and then turned on to achieve the function of non-contact unlocking, and can be connected with the remote device, so that it has wider application.
