In the drawings of the present invention, the same reference numerals represent the same or equivalent parts of the present invention. DETAILED DESCRIPTION

[0025] Reference will now be made in detail to various embodiments of the present invention, examples of which are shown in the accompanying drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments of the present invention, it should be understood that this specification is not intended to limit the present invention to the exemplary embodiments of the present invention described. On the other hand, the present invention is intended to cover not only the exemplary embodiments of the present invention, but also various alternative embodiments, modified embodiments, equivalent embodiments and other embodiments that may be included in the spirit and scope of the present invention defined by the appended claims.

[0026] Hereinafter, a contactless remote elevator calling system and method according to exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0027] Figure 1 FIG. 1 is a control block diagram showing a contactless remote elevator call system according to an exemplary embodiment of the present invention.

[0028] like Figure 1 As shown, the contactless remote elevator call system may include: a plurality of Bluetooth beacons 10 , a mobile device 20 , a cloud server 30 , an elevator server 40 , and a floor selector 50 .

[0029] A Bluetooth beacon is a device that uses low-power Bluetooth technology to achieve positioning. A Bluetooth beacon can create a signal coverage area around it and send signals at a predetermined period within the signal coverage area. When a mobile device enters the signal coverage area created by a Bluetooth beacon, the mobile device can be connected to the Bluetooth beacon. Once the mobile device is connected to the Bluetooth beacon, the mobile device can receive signals from the Bluetooth beacon.

[0030] A Bluetooth beacon 10 may be provided outside the elevator car of each floor, and the Bluetooth beacon 10 may be set to a broadcast mode. In the broadcast mode, the Bluetooth beacon 10 may start broadcasting signals at a predetermined period (e.g., 100 ms) after being powered on. The signal broadcast by the Bluetooth beacon 10 may include: a MAC address of the Bluetooth beacon 10, an RSSI value of the signal strength of the Bluetooth beacon 10, and a universal unique identifier (UUID) of the Bluetooth beacon 10.

[0031] The MAC address of the Bluetooth beacon 10 may indicate the physical address of the Bluetooth beacon, and is used to determine the floor information where the Bluetooth beacon is located.

[0032] The RSSI value of the signal strength of the Bluetooth beacon 10 may indicate the signal strength of the Bluetooth beacon received by the mobile device. The RSSI value is a relative strength value used to determine the distance between the Bluetooth beacon sending the signal and the mobile device receiving the signal.

[0033] As the transmission distance increases, the power of the signal broadcast by the Bluetooth beacon 10 decreases, and accordingly, the RSSI value also decreases. The RSSI value can be calculated as Wherein, P is the actual power of the signal broadcast by the Bluetooth beacon 10 received by the mobile device 20, in mW.

[0034] The calculation method of the RSSI value is not limited to this. For the same actual power P, the RSSI values ​​of Bluetooth beacons produced by different manufacturers may be different. Nevertheless, the distance between the Bluetooth beacon 10 sending the signal and the mobile device 20 receiving the signal can be determined based on the predetermined corresponding relationship between the RSSI value and the actual power P and the corresponding relationship between the actual power P and the transmission distance.

[0035] The UUID of the Bluetooth beacon 10 is unique to each Bluetooth beacon and is used to identify the Bluetooth beacon.

[0036] The mobile device 20 can be connected to multiple Bluetooth beacons 10 by Bluetooth to receive signals broadcast by the multiple Bluetooth beacons 10. The mobile device 20 can determine the distance from each Bluetooth beacon 10 based on the received signals broadcast by the multiple Bluetooth beacons 10. The mobile device 20 can be at least one of a user's mobile phone, a tablet computer, and a wearable device, and an application 21 for contactless remote elevator calling (hereinafter referred to as "application 21") can be installed in the mobile device 20.

[0037] When the user carries the mobile device 20 into the signal coverage area of ​​the Bluetooth beacon 10, the user can open the application 21 installed in the mobile device 20. When the application 21 is running, the application 21 can actively prompt the user whether to connect to the Bluetooth beacon 10, for example, by a pop-up window.

[0038] When the user determines to connect to the Bluetooth beacon 10, the mobile device 20 can simultaneously connect to multiple Bluetooth beacons 10 within the predetermined range of the mobile device via Bluetooth. Specifically, the mobile device 20 can connect to the Bluetooth beacon 10 whose RSSI value in the Bluetooth beacon is above a predetermined value (e.g., -100dBm). The distance of the Bluetooth connection is usually no more than 10m, so the mobile device 20 will not connect to the Bluetooth beacon 10 that is too far away.

[0039] Thus, the application 21 installed in the mobile device 20 can receive the signals broadcasted by the multiple Bluetooth beacons 10 connected thereto and perform signal processing on the received signals. As described above, the application 21 can determine the distance from each Bluetooth beacon 10 according to the RSSI value included in the received signal.

[0040] The application 21 may have a user interface, and the application 21 may display all Bluetooth beacons 10 within a predetermined range of the mobile device 20 and connected to the mobile device 20 on the user interface. The predetermined range may be divided into a plurality of intervals, such as very close, near, and far, according to the distance from the mobile device 20. According to the distance between the Bluetooth beacon 10 and the mobile device 20, the Bluetooth beacon 10 may be displayed in a corresponding interval on the user interface, so that the user may intuitively determine the distance between each Bluetooth beacon 10 and himself through the user interface. As an example, the Bluetooth beacon 10 in the very close interval may represent the Bluetooth beacon 10 set on the floor where the user is located.

[0041] In addition, when a building is provided with multiple elevators, multiple Bluetooth beacons 10 may be provided for each elevator. Each Bluetooth beacon 10 displayed on the user interface may be identified, multiple Bluetooth beacons 10 belonging to the same elevator may be identified in a similar manner (e.g., the same color and / or the same name), and Bluetooth beacons belonging to different elevators may be identified in different manners (e.g., different colors and / or different names), so that the user may easily distinguish the Bluetooth beacons of different elevators through the user interface. In addition, the RSSI value of the signal strength of each Bluetooth beacon 10 may be shown on the user interface. As an example, when two Bluetooth beacons belonging to different elevators are included in a very close interval, the user may determine that there are at least two elevators on the current floor.

[0042] Furthermore, the application 21 may determine the Bluetooth beacon 10 with the maximum RSSI value among the Bluetooth beacons as the Bluetooth beacon 10 closest to the mobile device 20 , and send out the signal of the Bluetooth beacon 10 closest to the mobile device 20 .

[0043] The cloud server 30 may be an external server that is remotely located and used for the contactless remote elevator call system. The cloud server 30 may be wirelessly connected to the mobile device 20. Thus, the cloud server 30 may receive a signal from the Bluetooth beacon 10 that is closest to the mobile device 20.

[0044] The cloud server 30 may pre-store a mapping table including the correspondence between the MAC address of the Bluetooth beacon 10 and the floor where the Bluetooth beacon 10 is located. When receiving a signal of the Bluetooth beacon 10 closest to the mobile device 20, the cloud server 30 may query the mapping table according to the MAC address of the Bluetooth beacon included in the received signal, thereby determining the floor where the Bluetooth beacon 10 closest to the mobile device 20 is located according to the mapping table. The cloud server 30 may determine the floor where the Bluetooth beacon 10 closest to the mobile device 20 is located as the floor where the mobile device 20 is located (i.e., the floor where the user is located). The cloud server 30 may send the determined floor information where the mobile device 20 is located to the outside.

[0045] The elevator server 40 may be a server that is locally set (i.e., set in the building where the elevator is located) and is used to control the elevator system 60. The elevator server 40 may be wirelessly connected to the cloud server 30. Thus, the elevator server 40 may receive the determined floor information of the mobile device 20 from the cloud server 30.

[0046] The floor selector 50 may be provided in the elevator and electrically connected (eg, via a cable) to the elevator server 40. Thus, the floor selector 50 may receive the floor information of the determined mobile device 20 from the elevator server 40, and call the elevator according to the floor information of the mobile device 20.

[0047] Further, the user can select the floor to go to through the application 21 of the mobile device 20, and the mobile device 20 can send the information of the floor to go to selected by the user to the cloud server 30. The cloud server 30 can send the received information of the floor to go to selected by the user together with the determined information of the floor where the user is located to the elevator server 40. The elevator server 40 can forward the received floor information to the floor selector 50. The floor selector 50 can control the elevator to first run to the floor where the user is located, and then run to the floor to go to selected by the user.

[0048] The wireless connection method may include any one of a short-range communication method and a long-range communication method, wherein the short-range communication method may include: wireless local area network (WiFi), Bluetooth, and the long-range communication method may include: microwave communication, mobile data network, and network cable.

[0049] In another exemplary embodiment, multiple elevators may be installed in a building, and the elevator server 40 may be a control device for controlling multiple elevators, and may grasp the real-time operation status of each elevator. The elevator server 40 may send the real-time operation status of each elevator to the cloud server 30. The cloud server 30 may select the most suitable elevator from multiple elevators to respond to the user's elevator call based on the real-time operation status of each elevator. Multiple elevators are usually installed in office buildings. During the peak period of elevator use during commuting, it is preferred that the cloud server 30 selects the elevator that can respond to the user's elevator call the fastest based on the real-time operation status of each elevator, rather than selecting the elevator closest to the user, thereby improving the elevator's operating efficiency and reducing the user's waiting time.

[0050] In this case, when the elevator call is determined, the cloud server 30 may send a signal requesting the elevator server 40 to provide the operation status of the elevator. The elevator server 40 may provide the cloud server 30 with data on the real-time operation status of multiple elevators. Upon receiving the data on the real-time operation status of multiple elevators, the cloud server 30 may perform data processing on the received data to determine the most suitable elevator among the multiple elevators. The cloud server 30 may send the most suitable elevator information among the determined multiple elevators together with the floor information where the mobile device 20 is located to the elevator server 40. The elevator server 40 may forward the received floor information where the mobile device 20 is located to the floor selector 50 of the most suitable elevator selected by the cloud server 30.

[0051] In yet another exemplary embodiment, the user may select an elevator to call from among multiple elevators, rather than the cloud server 30 selecting the elevator closest to the user or the most suitable elevator from among multiple elevators.

[0052] In this case, when determining to call an elevator, the user can select a Bluetooth beacon 10 from a plurality of Bluetooth beacons 10 within a predetermined range displayed on the user interface. The mobile device 20 can determine the elevator to which the Bluetooth beacon 10 selected by the user belongs, and determine the Bluetooth beacon 10 of the elevator that is closest to the mobile device 20, and then send the signal of the Bluetooth beacon 10 to the cloud server 30. The cloud server 30 can send the determined elevator information selected by the user and the floor information where the mobile device 20 is located to the elevator server 40. The elevator server 40 can forward the received floor information where the mobile device 20 is located to the floor selector 50 of the elevator selected by the user.

[0053] Figure 2 To illustrate signal transmission in a contactless remote elevator call system according to an exemplary embodiment of the present invention.

[0054] like Figure 2 As shown, the Bluetooth beacon 10 can broadcast a signal including the MAC address of the Bluetooth beacon, the RSSI value of the signal strength of the Bluetooth beacon, and the universal unique identification code information of the Bluetooth beacon.

[0055] The mobile device 20 can connect to the Bluetooth beacon 10 and receive the signal broadcast by the Bluetooth beacon 10. The mobile device 20 can perform signal processing on the received signal broadcast by the Bluetooth beacon 10 to determine the distance to each Bluetooth beacon, and send the signal of the Bluetooth beacon 10 closest to the mobile device 20 to the cloud server 30.

[0056] The cloud server 30 may process the signal received from the Bluetooth beacon 10 to determine the floor where the mobile device is located. When the floor where the mobile device 20 is located is determined, the cloud server 30 may send a message to the mobile device 20 requesting to determine whether to call the elevator.

[0057] The user can choose whether to call the elevator through the application 21 of the mobile device 20. When the elevator call is determined, the option of the floor to be visited can be further provided in the user interface of the application 21, and the user can select the floor to be visited. The mobile device 20 can send the information of the floor to be visited selected by the user to the cloud server 30.

[0058] When receiving the floor information sent by the mobile device 20, the cloud server 30 may send the received floor information selected by the user and the previously determined floor information where the mobile device 20 is located to the elevator server 40.

[0059] When receiving the floor information of the mobile device 20 and the floor information selected by the user, the elevator server 40 can forward the floor information of the mobile device 20 and the floor information selected by the user to the floor selector 50 of the elevator to which the Bluetooth beacon 10 closest to the mobile device 20 belongs.

[0060] When receiving the floor information forwarded by the elevator server 40, the floor selector 50 can control the operation of the elevator according to the floor information of the mobile device 20 and the selected floor information. The floor selector 50 can control the elevator to stop at the floor where the mobile device 20 is located, and after the user enters the elevator, the floor selector 50 can control the elevator to run to the floor selected by the user.

[0061] Figure 3 Flow chart showing a non-contact remote elevator calling method according to an exemplary embodiment of the present invention. Figure 1 The contactless remote elevator calling system shown is used to implement the contactless remote elevator calling method.

[0062] In step S101, a Bluetooth beacon disposed outside the elevator car on each floor may broadcast a signal to the outside, and the signal may include: a MAC address of the Bluetooth beacon, an RSSI value of the signal strength of the Bluetooth beacon, and a universal unique identifier (UUID) of the Bluetooth beacon.

[0063] In step S102 , the mobile device may connect with a Bluetooth beacon via Bluetooth communication and may receive a signal broadcast by the Bluetooth beacon.

[0064] In step S103 , the mobile device may perform signal processing on the received signal broadcast by the Bluetooth beacon to determine the distance from each Bluetooth beacon according to the RSSI value included in the signal broadcast by the Bluetooth beacon.

[0065] In step S104, according to the determined distances to the various Bluetooth beacons, the mobile device may determine the Bluetooth beacon with the maximum RSSI value among the various Bluetooth beacons as the Bluetooth beacon that is closest to the mobile device among the Bluetooth beacons.

[0066] In step S105 , the mobile device may send the signal of the Bluetooth beacon that is determined to be closest to the mobile device to the cloud server.

[0067] In step S106, when receiving the signal of the Bluetooth beacon closest to the mobile device, the cloud server may perform signal processing on the signal of the Bluetooth beacon to query the mapping table according to the MAC address of the Bluetooth beacon included in the signal. According to the mapping table, the cloud server may determine the floor where the Bluetooth beacon closest to the mobile device is located, and determine the floor where the Bluetooth beacon closest to the mobile device is located as the floor where the mobile device is located. The mapping table may include the correspondence between the MAC address of the Bluetooth beacon and the floor where the Bluetooth beacon is located.

[0068] In step S107, when the floor where the mobile device is located is determined, the cloud server may send a message to the mobile device requesting whether to call the elevator.

[0069] When the elevator call is determined, in step S108, the mobile device may provide an option of the floor to go to, the user may select the floor to go to through the mobile device, and the mobile device may send the information of the floor to go to selected by the user to the cloud server.

[0070] When receiving the floor information sent by the mobile device, in step S109, the cloud server can send the received user-selected floor information and the previously determined floor information of the mobile device to the elevator server.

[0071] When receiving the floor information of the mobile device and the floor information selected by the user, in step S110, the elevator server can forward the floor information of the mobile device and the floor information selected by the user to the floor selector of the elevator to which the Bluetooth beacon closest to the mobile device belongs.

[0072] When receiving the floor information forwarded by the elevator server, in step S111, the floor selector can control the operation of the elevator according to the floor information of the mobile device and the selected floor information to be visited, so as to transport the user to the selected floor.

[0073] The contactless remote elevator calling system and method according to the exemplary embodiment of the present invention can enable users to make contactless remote elevator calls through mobile devices without touching elevator buttons, thereby reducing health risks that may be caused by elevator calls.
