Fig. 1 shows a schematic view of an elevator floormanagement control system 1 according to an embodiment of the present invention, wherein the elevator floormanagement control system 1 can be used for performing floor management of an elevator.

As shown in fig. 1, the elevator floormanagement control system 1 includes anaccess control machine 10 and a hand-free key 20, and theaccess control machine 10 and anelevator control system 40 can perform information transmission. The hands-free key 20 may be held by a user, for example. Theaccess control machine 10 may be disposed in an elevator or inside an elevator (for example, but not limited to, in a control panel of an elevator). Anelevator control system 40 may also be provided within the elevator to control operation of the elevator. After the dooraccess management machine 10 and the hands-free key 20 are verified, theelevator control system 40 will open the elevator right to the user. The control panel of the elevator may be, for example, an OPB control panel (operation panel), but is not limited thereto.

The details of the doorlock management apparatus 10 and the hands-free key 20 will be described next. Fig. 2 shows the detailed component schematic diagram of the dooraccess management apparatus 10 and the hands-free key 20 according to the first embodiment of the present invention (for housing), and please refer to fig. 1 at the same time.

As shown in fig. 2, the dooraccess management apparatus 10 may include a circuit board 11, a processor 12, a Radio Frequency (RF)receiver 13, an elevatorsignal transceiver module 14, and a first Low Frequency (LF) transceiver 16. The processor 12, theradio frequency receiver 13, the elevatorsignal transceiver module 14, and the first low frequency transceiver 16 may be disposed on the circuit board 11. The processor 12 is electrically connected to therf receiver 13, the elevatorsignal transceiver module 14, and the first low frequency transceiver 16. In addition, the first low frequency transceiver 16 can transmit and receive low frequency signals through a low frequency antenna module 161, wherein the low frequency antenna module 161 can be disposed on the circuit board 11. In addition, therf receiver 13 may receive an rf signal through an rf antenna module 131, wherein the rf antenna module 131 may be disposed on the circuit board 11. In addition, the entranceguard management machine 10 can transmit and receive information to and from theelevator control system 40 through the elevator signal transmitting and receivingmodule 14. The hands-free key 20 may include aradio frequency transmitter 21 and a second low frequency transceiver 22. Theradio frequency transmitter 21 may be used to transmit radio frequency signals. The second low frequency transceiver 22 may be used to transceive low frequency signals.

When theelevator control system 40 is started (for example, when a user presses a key for going up or down a building, when an elevator door is opened, or someone enters an elevator, but not limited thereto), the accesscontrol management machine 10 and the hands-free key 20 can be mutually verified through the first low frequency transceiver 16, theradio frequency receiver 13, the second low frequency transceiver 22, and theradio frequency transmitter 21 to determine whether to transmit information to theelevator control system 40, so as to allow theelevator control system 40 to open the elevator right. In other words, when theelevator control system 40 is started, the dooraccess management station 10 automatically detects the hands-free key 20 in the elevator and performs verification.

More specifically, in one embodiment, when theelevator control system 40 is activated, theelevator control system 40 can send an activation message to the elevatorsignal transceiver module 14, and the elevatorsignal transceiver module 14 can trigger the processor 12 to operate after receiving the activation message. Then, the processor 12 may activate the first low frequency transceiver 16, the first low frequency transceiver 16 may send a low frequency signal to the hands-free key 20 through the low frequency antenna module 161, and the hands-free key 20 may receive the low frequency signal through the second low frequency transceiver 22. The hands-free key 20 may determine whether the low frequency signal is legitimate, for example, based on whether the communication protocol of the low frequency signal matches the communication protocol used by the hands-free key 20 (legitimate if the communication protocol matches, and illegitimate if the communication protocol does not match).

In one embodiment, when thedoor lock manager 10 does not detect the hands-free key 20 for more than a predetermined time, thedoor lock manager 10 and theelevator control system 40 may return to the sleep state.

In an embodiment, when the hands-free key 20 determines that the low frequency signal is legal, the hands-free key 20 may start therf transmitter 21, and therf transmitter 21 may transmit an identity signal of the hands-free key 20 to the dooraccess management apparatus 10, and then therf receiver 13 of the dooraccess management apparatus 10 may receive the identity signal through the rf antenna module 131, and the processor 12 may determine the identity of the hands-free key 20 according to the identity signal. Further, in an embodiment, the dooraccess management apparatus 10 may pre-store the identity information (such as, but not limited to, an identifier) of the correct hand-free key 20, and the identity signal transmitted by the key of the hand-free key 20 may include the identity information of the hand-free key 20, so that the processor 12 may determine whether the identity of the hand-free key 20 is correct according to the content of the identity signal.

In one embodiment, the identification signal also includes one or more floor information corresponding to the hands-free key 20, so that when the processor 12 determines that the identity of the hands-free key 20 is correct (matches the pre-stored identity information), the processor 12 can transmit the floor information to theelevator control system 40 through the elevatorsignal transceiver module 14. When theelevator control system 40 receives the floor information, the authority of the floor corresponding to the floor information can be opened; here, "permission to open a floor" may be, for example, permission to open a button of the floor(s) on a control panel of the elevator, allowing a user to select and go to the floor, or may be automatically sent to the floor (preferably, in the case where the hands-free key 20 corresponds to one floor), and is not limited thereto.

In an embodiment, the aforementioned start information, the low frequency signal or the identity signal may be encrypted by Advanced Encryption Standard (AES), but is not limited thereto. In one embodiment, the activation information, the low frequency signal, or the identity signal may be transmitted encrypted using 128-bit advanced encryption standard (AES-128), but in other implementations, other bits of advanced encryption standards may be used. Therefore, the elevator floormanagement control system 1 can provide a high-security authentication mechanism.

The details of each component are described next.

In one embodiment, the dooraccess management machine 10 sends a low frequency signal, and the hands-free key 20 can detect the low frequency signal within the elevator room through the second low frequency transceiver 22 and reply; in other words, as long as the distance between the hands-free key 20 and the doorlock management station 10 is within about 4 to 5 meters (or adjusted according to the size of the elevator car), the doorlock management station 10 can receive the rf signal returned by the hands-free key 20. Therefore, when the user enters the elevator, even if the hands-free key 20 is placed in the pocket or leather bag of the user, theaccess control machine 10 can still receive the rf signal sent by the hands-free key 20, and notify theelevator control system 40 of the authority of opening the floor corresponding to the hands-free key 20 after the authentication is successful. Compared with the prior art, the utility model discloses can let the user need not to take out hand-free formula key 20 and can respond to, not only can save time cost, do and promote the convenience. It should be noted that the above detection range is only exemplary and not limiting.

In an embodiment, the dooraccess management apparatus 10 may include apower supply module 17, wherein thepower supply module 17 may include a battery (e.g., a disposable battery or a rechargeable battery), or thepower supply module 17 may directly supply power through the commercial power. In one embodiment, the hands-free key 20 may also have a battery (e.g., a disposable battery or a rechargeable battery) therein. In another embodiment, the hands-free key 20 may have a coil inside and act by electromagnetic induction; the present invention is not limited thereto.

In one embodiment, theelevator control system 40 may provide an alarm, for example, when the processor 12 determines that the received rf encrypted signal is illegal (for example, the rf encrypted signal does not have the authentication code of the resident, the rf encrypted signal fails to be decrypted, and the like, but not limited thereto), theaccess control system 10 may notify theelevator control system 40, and theelevator control system 40 may issue an alarm. In one embodiment, the alert prompt may be an alert prompt tone. In one embodiment, the alert prompt may also be a message sent by theelevator control system 40 to an electronic communication device such as a computer, cell phone, etc. of a cell manager, guard, or user. The present invention is not limited thereto.

In one embodiment, theelevator control system 40 may provide a speaker that may emit a key prompt tone, for example, when a user operates a floor key on the control panel of the elevator. In addition, the speaker may also be used to emit an alarm alert. The present invention is not limited thereto.

In an embodiment, theelevator control system 40 may also additionally provide a key touch module, for example, a physical key or a touch screen (different from a floor key) may be additionally disposed on the control panel of the elevator, and the key touch module may be electrically connected to the physical key or the touch screen, and the key touch module may receive a password input by the user through the physical key or the touch screen. After the key touch module receives the password, theelevator control system 40 may determine whether the password is correct (theelevator control system 40 stores the door-opening password set by the user), or may transmit the password input by the user to theaccess control machine 10, so as to determine whether the password is correct (theaccess control machine 10 stores the door-opening password set by the user) through the processor 12. When correct, theelevator control system 40 may open the authority of the floor corresponding to the password (otherwise, no reaction occurs). Thus, when the user forgets to carry the hands-free key 20, the user can still verify the door-open password by manually entering the door-open password.

In one embodiment, theelevator control system 40 may be provided with a memory. For example, after theelevator control system 40 receives the floor information, the memory can record the floor information, so theelevator control system 40 can have the effect of recording the flow of people entering and leaving the floor, and further the effect of the access control management is more appropriate.

In an embodiment, as long as it is reasonable, the functions of the speaker, the key touch module, the alarm prompt or record, and the like of theelevator control system 40 can be implemented by the accesscontrol management machine 10 instead; alternatively, various functions of theaccess control machine 10 may be implemented by theelevator control system 40 instead. In other words, as long as it is reasonably realized, the modules inside theelevator control system 40 and theaccess control machine 10 can be replaced arbitrarily according to the requirement.

The above components are merely examples, and the contents thereof may be arbitrarily increased or decreased or adjusted as needed.

Next, details of the operation flow of the dooraccess management machine 10 and the hands-free key 20 of the first embodiment will be described, please refer to fig. 1 to 4 together, wherein fig. 3 is an operation flow chart of the elevator floormanagement control system 1 according to an embodiment of the present invention, and fig. 4 is a schematic view of an operation situation of the elevator floormanagement control system 1 according to an embodiment of the present invention.

Thereafter, step S02 is executed, and the processor 12 activates the first low frequency transceiver 16 to send a low frequency signal to the hands-free key 20 through the low frequency antenna module 161, wherein the second low frequency transceiver 22 of the hands-free key 20 can receive the low frequency signal.

Then, step S03 is executed to determine whether the low frequency signal is legal or not by the hands-free key 20.

If not, step S04(b) is executed to stop the current process of the hands-free key 20. In one embodiment, the hands-free key 20 may ignore thedoor access manager 10 and does not respond, so the elevator remains stationary.

If so, step S04(a) is executed to enable the hands-free key 20 to activate therf transmitter 21 to transmit the identity signal of the hands-free key 20, wherein the identity signal includes identity information and floor information.

Then, step S05 is executed, therf receiver 13 of the dooraccess management station 10 receives the identity signal through the rf antenna module 131, and the processor 12 determines whether the identity information of the hands-free key 20 is correct according to the identity signal.

If not, step S06(b) is executed and the processor 12 stops the current flow. In one embodiment, the processor 12 may disregard the hands-free key 20 and not perform any reaction. So that the elevator also remains stationary.

If so, step S06(a) is executed, and the processor 12 transmits the floor information corresponding to the hands-free key 20 to theelevator management system 40 via thetransceiver module 14. When the floor information is received, theelevator management system 40 may release the authority of the floor corresponding to the floor information, so that the elevator may travel to the floor.

Therefore, as shown in fig. 4, when a user enters the elevator, the dooraccess management station 10 can automatically search the hands-free key 20 and perform mutual authentication with the hands-free key 20, and when the authentication is successful, theelevator management system 40 can open the right of the correct floor, so that the user can operate on the control panel of the elevator to select the floor, or the elevator can automatically go to the floor. Therefore, when the user holds a large number of articles or is inconvenient to take out the hands-free key 20, the dooraccess management machine 10 can automatically authenticate the hands-free key 20 on the user, thereby improving convenience.

Therefore, the utility model provides an elevator floor supervisory control system, entrance guard management board and hand-free formula key of improvement not only have security and convenience more than current mechanism, still can reduce the time cost of resident family.
