[0001] DESCRIPTION
[0002] Wireless electronic lock with antenna plate and multifunction adapter.
[0003] Field of invention
[0004] This invention concerns a wireless electronic lock with a multi-function attachable antenna plate, which, by incorporating the attachable antenna plate without the need for wiring, allows, through an intermediate instruction chip, the operational or functional alternation of a passive booster antenna and a passive transponder antenna to amplify the information emitted from a passive antenna such as that of an RFID card, as well as to receive information from a data input device such as a keyboard.
[0005] Prior art
[0006] Currently, the use of lockers is widespread for users to temporarily store their personal belongings in both public and private spaces, such as transport stations, supermarkets, schools, gyms, or swimming pools. Each locker has an independent lock that controls its opening and closing. Locks can be mechanical (operated with a key) or electronic (the locking mechanism is operated by an electric motor controlled by various means, such as a keypad or an RFID-enabled device like a card).
[0007] Lockers equipped with electronic locks are, in most cases, not connected to any central control unit and operate independently (each electronic lock has its own autonomous control element, neither linked nor interchangeable with any other lock). The electronic components of these locks require a power supply to operate. This power can be provided by cable, which requires running a power cable from the outlet to each lock, passing through the locker, or locally and in isolation via a battery in each lock. Powering electronic locks by cable has the advantage of virtually eliminating power supply problems, except in the event of a general failure in the installation's power system or a rare fault in one of the power cables. However, it does have some drawbacks.For example, when the power comes from a wall outlet, a cable must be run from the outlet to each lock. Furthermore, if the locker unit needs to be relocated, another power cable must be run to the new location, requiring a new electrical installation. This is costly and sometimes even impractical. Additionally, once the unit is manufactured, it is difficult to adapt it or create grooves or channels to conceal the wiring.
[0008] To avoid the laborious and complicated process of powering each locker in the facility by cable, in many cases the electronic locking systems are powered individually by batteries, but this requires periodically replacing the battery in time before it runs out, so it is desirable that the lock consumes the least possible energy to maximize the life of each battery.
[0009] In electronic locks that communicate via RFID signals, there are known methods for both mitigating RFID signal interference when these locks are installed on metal doors and for amplifying the signal to reduce energy consumption. Among these methods are elements with metal cores that filter the RFID signal. However, these elements are not capable of receiving or transmitting data; they only amplify the signal emitted by other elements.
[0010] RFID signals are commonly transmitted from devices such as cards, tags, wristbands, etc. These devices are first "written" with the access data and, by receiving external power, transmit the data via the RFID signal. However, these devices alone cannot overcome interference from other signals or metallic objects. Therefore, the card or other device must be repeatedly brought close to the reader or antenna for it to be read correctly. Furthermore, when these types of locks detect a card in their vicinity, they transmit power to the card and then read it. If the card is not read, the process must be repeated several times, thus wasting a significant amount of energy.
[0011] Summary
[0012] In contrast to the prior art, the present technology relates to a wireless electronic lock with a multi-function attachable antenna plate. The wireless electronic lock can be activated by a portable opening device and comprises a first antenna embedded within a surface of the lock, such as a doorknob. The wireless electronic lock has a multi-function antenna plate attached to the surface of the lock or the element on which it is installed. The multi-function attachable antenna plate comprises a data input device and a second antenna. In some embodiments, the multi-function attachable antenna plate can be glued, nailed, or screwed to the surface of the wireless electronic lock, or retrofitted to the surface of the wireless electronic lock.
[0013] The second antenna on the board - a multi-function attachable antenna - can be configured to boost a signal between the wireless electronic lock and the portable opening device, such as an RFID card, in one function, and the second antenna can be configured to transfer data from the data input device for comparison with the data stored in the wireless electronic lock in a second function.
[0014] In one function, the second antenna amplifies the signal between the wireless electronic lock and the portable opening device when the portable opening device is near the wireless electronic lock, both to lock an open locker and to open a locked locker. Here, "nearby" can mean 30.5 cm (twelve inches) or less, although it can be more than 30.5 cm (twelve inches) in other embodiments, up to, for example, 61 cm (two feet).
[0015] In a second function, the second antenna transfers data from the data input device, such as a keypad or fingerprint reader, for comparison with the data stored in the wireless electronic lock. This comparison is made possible by the memory, which stores the data from the wireless electronic lock, and one or more processing devices, which compare the data from the data input device with the data stored in the wireless electronic lock's memory.
[0016] This technology also refers to a wireless electronic lock with a multi-function attachable antenna board. The multi-function attachable antenna board can switch between amplification and transmission / reception functions via its passive antenna. In this way, the multi-function attachable antenna board can amplify the signal from the portable opening device communicating with the active antenna of the wireless electronic lock using either the passive antenna booster or amplification function. The multi-function attachable antenna board enables communication between the wireless electronic lock and a data input device using either the passive transponder antenna or a transmission / reception function via an intermediate chip.Electronic locks, for security purposes, require valid access data to open the door, drawer, or other item they secure. This access data identifies an authorized user. Traditionally, electronic locks that communicate via RFID signals emit radio frequency waves through an antenna. The antenna in an electronic lock is usually an active antenna that emits energy via radio frequency. To improve the lock's energy efficiency, the antenna only emits energy upon user activation, for example, by pressing the lock knob. This energy powers a chip within a portable opening device, such as a card, wristband, or other access control device, activating it and transmitting the stored access data.
[0017] Using the multi-function attachable antenna plate, without the need for additional wiring, the passive booster antenna amplifies the signal from the portable opening device, ensuring an accurate reading on the first attempt without the need for repetitions. This also saves energy by eliminating the need to repeatedly power the portable opening device for a single reading. Furthermore, thanks to the passive transponder antenna function of the attachable antenna plate, a data input device can communicate wirelessly with the electronic lock.To store this communication, an intermediate chip on the attachable antenna board receives the access data from the data input device. Subsequently, the wireless electronic lock emits enough energy for the intermediate chip on the attachable antenna board to transmit the stored access data. Thus, thanks to the passive transponder antenna, which operates in a transmission-reception mode, it is possible to wirelessly connect a data input device, such as a keypad, to a pre-existing wireless electronic lock without modifying the lock itself. This is achieved simply by placing the attachable antenna board on the door (preferably adhered to the exterior surface with adhesive), thereby providing the wireless electronic lock with greater versatility in its opening and installation methods.
[0018] The attachable antenna board consists of two layers. The second layer comprises the passive antenna and the intermediate chip, while the first layer is made of Ferhta, which acts as an interference filter. This interference filter is useful on metal doors, as the metal of the door can cause communication interference. Alternatively, the first layer can be Ferhta-free for applications involving non-metallic doors. Thanks to this configuration of the attachable antenna board, in addition to the signal amplification provided by the passive booster antenna, the first Ferhta layer isolates the signal from interference caused by metallic elements, such as metal locker doors. Ideally, the attachable antenna board should be placed concentrically around the knob of the wireless electronic lock or the point where the lock receives the signal.In this way, the knob is completely surrounded by the attachable antenna plate, thus ensuring operation regardless of where the portable opening device is located.
[0019] The passive booster antenna and the passive transponder antenna are integrated into a single passive antenna, whose operational switching is determined by an intermediate chip. In this way, the same passive antenna is used to perform both functions.
[0020] In this way, the passive antenna typically functions as a passive booster antenna. Since the booster function is performed by the antenna's own configuration, it does not require power and can operate indefinitely in this mode. The passive antenna on the attachable antenna board is only used as a passive transponder antenna when access data is entered via a data input device such as a keyboard, fingerprint reader, QR code reader, iris scanner, facial recognition system, voice recognition, etc.
[0021] When a user enters data into a data entry device by pressing the "enter" button, the microcontroller integrated into the device commands the intermediate chip of the attachable antenna board to switch to a passive transponder antenna, functioning as a transponder. The data entry device then transmits the user's input data, which is stored in the intermediate chip of the attachable antenna board. When the wireless electronic lock is activated, for example, by pressing the doorknob, it sends power via its active antenna to the attachable antenna board. With the power received from the wireless electronic lock, the attachable antenna board is able to transmit the data stored in the intermediate chip to the wireless electronic lock to open it.
[0022] The intermediate chip is capable of determining the communication between the data input device and the wireless electronic lock by storing the access data transmitted from the data input device and subsequently retrieving it via the active antenna of the wireless electronic lock. In this way, and to improve the energy efficiency of both the data input device and the wireless electronic lock, access data is transmitted from the data input device when the "enter" button is pressed and received by the wireless electronic lock, for example, when the doorknob is pressed, making it very difficult for the user to perform these actions simultaneously.To determine communication between the data input device and the wireless electronic lock, the intermediate chip stores the access data transmitted from the data input device, thus allowing the user to activate the reception of access data in the wireless electronic lock, for example, by pressing the knob.
[0023] Enabling the passive antenna as a passive transponder antenna by the intermediate chip is done for a predetermined time, enough for the user to activate the reception of access data in the electronic lock, for example, by pressing the knob.
[0024] The time during which the passive antenna is enabled as a passive transponder antenna is predetermined and must be sufficient to allow the user to activate the reception of access data in the wireless electronic lock, for example, by pressing the knob, this time being in the range of between 3 and 8 seconds.
[0025] Additionally, the passive booster antenna and the passive transponder antenna are integrated into a single passive antenna whose alternating operation is determined by the intermediate chip.
[0026] In this way, both functions, booster function and transponder function, can be performed with a single antenna, without the need to use a different antenna for each function, thus simplifying the design, allowing it to be more compact and without interference problems between antennas, thanks mainly to the fact that the function is controlled and determined by the intermediate chip, giving versatility to the lock in relation to the opening device to be used.

[0054] Exhibition of a preferred achievement
[0055] With reference to the drawings and references listed above, a preferred embodiment of the invention is illustrated in the accompanying drawings. In general, the present technology relates to a non-invasive improvement of RFID-based wireless electronic locker locks (1) by adding a secondary identification method, such as a keypad or fingerprint reader, without requiring modification of the locker door. The present technology utilizes wireless communication between the lock components. For example, the present technology leverages the lock's existing RFID antenna to enable wireless communication between the external data input device (4) (e.g., keypad or fingerprint reader) and the internal wireless electronic lock mechanism (1), eliminating the need to drill holes in the door.
[0056] The lock using this technology can be divided into two main assemblies: The first assembly comprises the primary wireless RFID electronic locking mechanism (1), which operates independently when used with a portable opening device (3) such as a traditional RFID card. It has an internal active antenna (1a) within a knob (1b), connected to the main electronic board (PCB). The second assembly comprises a new identification module mounted on the outer surface of the door, containing a data input device (4), such as a keypad (or alternative input), a passive antenna (2b), and a power source (5) (such as a solar panel). This module adheres to the door, allowing for easy installation without drilling.
[0057] This technology includes dual-mode antenna functionality. In data entry device mode (4), keypad mode, the passive antenna (2b) connects to an NFC (Near Field Communication) tag, or NTAG, when the keys are pressed, enabling data transmission for validation. In standard RFID mode, portable opening device mode (3), when the keypad is not in use, the passive antenna (2b) acts as a booster, amplifying the electromagnetic field to improve communication between the active antenna (1a) of the wireless electronic lock (1) and the RFID card presented by the user. When using the keypad, the user enters a code that temporarily connects the passive antenna (2b) to the NTAG for a period of time, for example, 5 seconds.The lock reads the code entered through the active antenna (1a) in the knob (1b) allowing the user to unlock the lock by pressing the knob (1b) within the timing window.
[0058] These innovative features provide a non-invasive dual authentication option for RFID locks, allowing flexibility in identification methods and greater signal range without structural modifications.
[0059] With reference to the wireless electronic lock (1) described in the figures, the wireless electronic lock (1) comprises a multi-function attachable antenna plate (2). The multi-function attachable antenna plate (2) is capable of amplifying the signal from the portable opening device (3) in communication with the active antenna (1a) of the wireless electronic lock (1) by means of the passive booster antenna (2b1) or with amplification function. This enables communication of the wireless electronic lock (1) with the data input device (4) via the intermediate chip (2b3) using the passive transponder antenna (2b2) or with transmission and reception function.
[0060] As a security measure, electronic locks require access data to open the door. This access data is validated by the lock by comparing it with authorized data stored in the internal memory of the wireless electronic lock (1). This allows the lock to be identified as an authorized user, enabling it to open, or denying access if the user is not authorized. Electronic locks that communicate via RFID signal emit radio frequency waves through the antenna. Preferably, the antenna of the wireless electronic lock (1) is an active antenna (1a) that, in addition to transmitting and receiving data via radio frequency, also emits energy via radio frequency.To improve the energy efficiency of the wireless electronic lock (1), the active antenna (1a) only emits power upon user request, preferably by pressing the knob (1b). The power emitted by the wireless electronic lock (1) via the active antenna (1a) drives a chip within a portable opening device (3), such as a card, wristband, or other opening device, enabling it to activate and transmit the access data it contains to the wireless electronic lock (1).
[0061] The present technology operates in two modes. The first mode uses a portable opening device (3), such as an RFID card, to authenticate a user and open a lock. Using the attachable multifunction antenna plate (2), the passive booster antenna (2b1) amplifies the signal from the portable opening device (3), ensuring a successful first reading without the need for repetitions. This results in energy savings, as the portable opening device (3) does not need to be powered multiple times for a single reading. In this first mode, a user can hold the portable opening device (3) near the knob (1b) to close an open locker and also to open a closed locker. Here, "near" can mean 30.5 cm (twelve inches) or less, although it can be more than 30.5 cm (twelve inches) in other embodiments, up to, for example, 61 cm (two feet).
[0062] In a second mode, the present technology uses a data input device (4), such as a keypad or fingerprint reader, attached to one side of the wireless electronic lock (1) to authenticate users and unlock the lock. In some embodiments, to add the functionality of a data input device (4) to an RFID system, a multi-function attachable antenna plate (2) is attached to the front of the lock (on an exterior surface facing the user). An inner surface of the multi-function attachable antenna plate (2) may include a passive antenna (2b). An outer surface of the multi-function attachable antenna plate (2) may include a data input device (4) (keypad, fingerprint reader, etc.) and a power source (5), such as a solar panel. This assembly is attached to the door, for example, with an adhesive.This assembly has a hole through which the lock knob (1b) can be inserted. Thanks to the passive transponder antenna (2b2) on the attachable antenna board (2), the data input device (4) can communicate with the electronic lock wirelessly (1). To enable communication between the data input device (4) and the electronic lock wirelessly (1), the attachable antenna board (2) receives the access data transmitted by the data input device (4) along with a specific amount of energy. The transmitted energy commands (activates the passive transponder antenna operating mode (2b2)) the intermediate chip (2b3) on the attachable antenna board (2).The intermediate chip (2b3) stores the access data and enables the passive transponder antenna (2b2). Subsequently, the wireless electronic lock (1) emits sufficient power for the attachable antenna plate (2) to transmit the access data stored in the intermediate chip (2b3). Thus, thanks to the passive transponder antenna (2b2), which functions as both a transponder (transmitter and receiver), it is possible to wirelessly connect a data input device (4), such as a keypad, to a pre-existing wireless electronic lock (1) without modifying the lock. This is achieved simply by placing the attachable antenna plate (2) on the door, thereby providing the existing wireless electronic lock (1) with greater versatility in its opening modes.
[0063] In a preferred embodiment, shown in Figure 1 and other figures, the data input device (4) and the attachable antenna plate (2) are integrated into a single unit by means of a housing, thus reducing the number of components mounted on the door. This configuration is more suitable for confined spaces. In other embodiments, the data input device (4) and the attachable antenna plate (2) are separate components, facilitating the placement of the data input device in an accessible position or even on another nearby element such as a wall.
[0064] The attachable antenna board (2) consists of two layers (2a). The second layer (2a2) comprises the passive antenna (2b) and the intermediate chip (2b3), while the first layer (2a1) is made of ferrite, which acts as an interference filter. This interference filter is useful for metal doors, as the metal of the door can cause interference in communication. Alternatively, the first layer (2a1) can be ferrite-free for applications involving non-metallic doors.
[0065] Thanks to this configuration, the attachable antenna plate (2) is equipped with, in addition to the signal amplification provided by the passive booster antenna (2b1), isolation from signal interference caused by metallic elements, such as metal locker doors, provided by the ferrite sheet. Preferably, the attachable antenna plate (2) should be positioned concentrically around the knob (1b) of the wireless electronic lock (1) or the point where the lock receives the signal. In this way, the active antenna (1a) that receives the signal, located on the knob (1b), is completely surrounded by the attachable antenna plate (2), thus ensuring operation regardless of the approach angle of the portable opening device (3).
[0066] The passive booster antenna (2b1) and the passive transponder antenna (2b2) are integrated into a single passive antenna (2b), the switching of which is determined by the intermediate chip (2b3). The same passive antenna (2b) is used to perform both functions (booster function and transponder function).
[0067] The intermediate chip (2b3), via command from the data input device's microcontroller (4), determines the operational switching between booster and transponder functions by activating or deactivating the radio frequency communication of the passive antenna (2b) (the passive booster antenna (2b1) would have radio frequency communication deactivated, and the passive transponder antenna (2b2) would have radio frequency communication activated). To achieve this, the intermediate chip (2b3) has a pin which, when energized with a voltage exceeding a preset limit, can switch radio frequency communication on or off. The energy required for this activation is supplied by the data input device (4).This energy is very small and, combined with the low power consumption of the data input device (4), allows this data input device (4) to operate even using a power supply (5) such as a small solar panel instead of batteries. Alternatively, the intermediate chip (2b3) can perform the on / off function for radio frequency communication using commands received from the data input device (4). In this way, the passive antenna (2b) typically functions as a passive booster antenna (2b1).Since the booster function is performed by the configuration (arrangement) of the passive booster antenna (2b1) and the radio frequency communication is deactivated, it can function indefinitely in this mode, determining the use of the attachable antenna plate (2) as a passive transponder antenna (2b2) and activating the radio frequency communication only in cases where access data is entered by means of a data input device (4) such as a keyboard or a fingerprint reader.
[0068] When a user enters data into a data input device (4) by pressing the enter button, the data input device (4) sends an activation command to the attachable antenna board (2). The intermediate chip (2b3) located on the attachable antenna board (2), upon receiving the command from the data input device (4), activates and switches from passive booster antenna (2b1) to passive transponder antenna (2b2), functioning as a transponder. The data input device (4) then transmits the data entered by the user to the passive transponder antenna (2b2) on the attachable antenna board (2), which receives the data. The data transmitted by the data input device (4) is stored in the intermediate chip (2b3).Upon waking or activation of the wireless electronic lock (1), for example, by pressing the knob (1b), it sends power to the attachable antenna board (2) via its active antenna (1a). With the power received from the wireless electronic lock (1), the attachable antenna board (2) is able to transmit the access data stored in the intermediate chip (2b3) to the wireless electronic lock (1) so that the wireless electronic lock (1) can validate the access data and allow the lock to be opened.
[0069] The intermediate chip (2b3) is capable of determining the communication of the data input device (4) with the wireless electronic lock (1) by storing the access data emitted from the data input device (4) and subsequently retrieving it through the active antenna (1a) of the wireless electronic lock (1).
[0070] Access data is transmitted from the data input device (4) when the enter button is pressed, and the access data is received by the wireless electronic lock (1), preferably by pressing the knob (1b). Therefore, it is very difficult for the user to perform these actions simultaneously, preventing communication between the data input device (4) and the wireless electronic lock (1). To enable communication between the data input device (4) and the wireless electronic lock (1), the intermediate chip (2b3) stores the access data transmitted from the data input device (4), thus allowing the user to activate the reception of access data by the electronic lock (1) when pressing the knob (1b).
[0071] The intermediate chip (2b3) enables the passive antenna (2b) as a passive transponder antenna (2b2) for a predetermined time, sufficient for the user to activate the reception of access data in the wireless electronic lock (1), by pressing the knob (1b).
[0072] The duration for which the passive antenna (2b) functions as a passive transponder antenna (2b2) is predetermined by the microcontroller of the data input device (4). The intermediate chip (2b3) receives the command to enable / disable the passive transponder antenna (2b2), at which point the passive antenna (2b) functions as a passive booster antenna (2b1) after a predetermined time. Thus, the operating time of the passive antenna (2b) as a passive transponder antenna (2b2) must be sufficient to allow the user to activate the reception of access data in the wireless electronic lock (1) by pressing the knob (1b). This time is predetermined to be between 3 and 8 seconds, with 5 seconds being preferred.
[0073] Figure 10 is a flowchart of the operation of the lock assembly described above. In step 100, it is determined whether a start button (e.g., on a data input device (4), such as a keypad) has been pressed. Each time the user presses a key (step 108), the keypad enables the passive antenna (2b) to function as a passive transponder antenna (2b2) and connects to the intermediate chip (2b3) for 5 seconds, resetting the timer each time a key is pressed (steps 102-112). Once the code has been entered via a series of key presses, the user presses the knob (1b) by hand (step 114). If the entered data is valid, the wireless electronic lock (1) will open (step 124). If the user does not press the knob (1b) within 5 seconds, or an incorrect code is entered, i.e., the data entered is invalid (step 126), the lock will not open, and the data entered will be erased (step 122).
[0074] On the other hand, if the start button is not pressed in step 100, the passive antenna (2b) does not connect to the intermediate chip (2b3) (steps 118-120), and the passive antenna (2b) instead functions as a passive booster antenna (2b1). This means that this antenna will only amplify the surrounding electromagnetic field, improving communication between the active antenna (1a) (located on the wireless electronic lock (1)) and the antenna of the portable opening device (3) that the user presented to the wireless electronic lock (1).
[0075] Variations in materials, shape, size and arrangement of the component elements, described in a non-limiting manner, do not alter the essential nature of this invention, and this is sufficient to proceed with its reproduction by an expert.
