[0047] The embodiment of the present application provides a contactless elevator control system based on identity recognition. Figure 1 1 is a schematic diagram of a contactless elevator control system based on identity recognition according to an exemplary embodiment, the system comprising:

[0048] An identity recognition device 101 is deployed in the elevator car and is used to recognize the target identity characteristics of a target user entering the elevator car;

[0049] In this embodiment, the identity recognition device 101 can be a device that can obtain and identify the biometric information of a user entering the elevator car without contact based on biometric recognition technology. For example, it can be a face recognition device, an iris recognition device, a voiceprint recognition device, etc. One or more types of identification devices can be selected and installed according to the actual use environment and needs. This embodiment does not limit this.

[0050] As an embodiment, the identity recognition device 101 may include one or more identity recognition modules. If multiple identity recognition modules are used, each identity recognition module may be installed at a different position in the elevator car to identify the user from different angles to improve the recognition accuracy. Preferably, as an embodiment, the identity recognition device 101 uses a face recognition device, which includes two face recognition modules, referred to as a first face recognition module and a second face recognition module. The first face recognition module faces the direction of the elevator car door after deployment, and the second face recognition module faces the opposite direction of the elevator car door after deployment. The target identity sub-features of the target user entering the elevator car are identified from two angles, which are respectively recorded as the first target identity sub-feature and the second target identity sub-feature. Optionally, a valid target identity sub-feature can be selected from the two target identity sub-features as the target identity feature of the target user. For example, when the second face recognition module fails to fully acquire the second target identity sub-feature due to reasons such as angle, recognition range, or occlusion by others, or the acquired second target identity sub-feature is fuzzy or of poor quality, the complete and valid first target identity sub-feature is selected as the target identity feature of the target user; optionally, the first target identity sub-feature and the second target identity sub-feature can also be spliced ​​to obtain feature data with clearer and richer feature information as the target identity feature of the target user, and so on.

[0051] Optionally, when the above-mentioned elevator arrives at the target floor and the elevator car opens, a second facial recognition module facing the opposite direction of the elevator car door can be used to identify the identity characteristics of the user leaving the elevator car, and the identity characteristics of the floor where the elevator is currently staying and the user leaving the elevator car on this floor are recorded and archived for subsequent call or query, such as for epidemic tracing.

[0052] And, the identity recognition device 101 is used to search for the associated floor information corresponding to the target identity feature in the stored correspondence between the identity feature and the floor information, or send the acquired target identity feature to an external server, and the external server searches for the associated floor information corresponding to the target identity feature in the stored correspondence between the identity feature and the floor information, receives the associated floor information returned by the external server, and pushes the associated floor information to the floor decision device 102;

[0053] In this embodiment, after the identity recognition device 101 recognizes the target user entering the elevator car and obtains the target identity feature, it is necessary to obtain the floor information of the target user based on the target identity feature according to the correspondence between the stored identity feature and the floor information. The floor information corresponding to the above target identity feature is called the associated floor information. After obtaining the above associated floor information, the information is pushed to the floor decision device 102.

[0054] As an embodiment, the correspondence between the above-mentioned identity features and floor information can be stored in the identity recognition device 101, and after obtaining the target identity features, the corresponding associated floor information can be directly searched in the locally stored correspondence; the identity recognition device 101 can also send the obtained target identity features to an external server, and the external server can search for the corresponding associated floor information in the correspondence between the identity features and floor information stored therein and send it to the identity recognition device 101, and the identity recognition device 101 can directly receive the associated floor information returned by the external server.

[0055] As an embodiment, for the correspondence between the above-mentioned identity features and floor information, the identity features and floor information can be directly associated and stored, and the corresponding floor information can be directly queried after the identity features are obtained; or the identity features, floor information, and identity information (such as name, work number, user ID, etc.) can be stored, and after obtaining the identity features, the identity information of the user corresponding to the identity features is first determined, and then the floor information is searched based on the identity information. This embodiment does not limit this.

[0056] As an embodiment, the correspondence between the above-mentioned identity features and floor information can be automatically generated and stored based on the elevator usage record of the target user in the historical period, or it can be obtained from the user information system associated with the user, for example, obtained and stored from the user information system by the identity recognition device 101, obtained and stored from the user information system by the above-mentioned external server, or obtained from the user information system by the above-mentioned external server and pushed to the identity recognition device 101 for storage, and this embodiment does not limit this.

[0057] Among them, the above-mentioned user information system refers to a system that stores information of users who will use the above-mentioned elevators. For example, for elevators installed in residential buildings, the above-mentioned user information system can be the resident information system of the building or the community. For elevators installed in office buildings, it can be the employee information system of the building or the park. In addition, it can also be combined with a visitor system or a conference system to obtain relevant information of users who need to temporarily use the above-mentioned elevators.

[0058] As an embodiment, the employee information system stores the employee's identity information, identity features, and floor information. For example, for a certain employee, the identity information stores his name, work number, etc.; the identity features store the employee's registered face recognition data or iris recognition data, etc., corresponding to the type of identity recognition device actually selected by the elevator; the floor information stores the floor information related to the employee, which can be the most relevant floor or multiple floors. For example, it can only store that his office is located on the tenth floor of the building, or it can store that his lounge is located on the fifth floor of the building, the fitness room is located on the third floor, the cafeteria is located on the second floor of the building, and the fixed parking space is located on the second underground floor of the building, etc. In addition, other information can be recorded in the employee information system, such as the elevator number of a specific elevator available to the employee, etc. This embodiment does not limit this. The resident information system can be implemented in a similar manner to the employee information system, which will not be repeated.

[0059] As an example, the conference system can record the start time, end time, names of participants, contact information, conference floor, participant identity data, etc. of each meeting related to the building, where the participants can include fixed employees in the building and external visitors who attend the meeting, so that external visitors can also use the above elevators without contact. The visitor system can be implemented in a similar way to the conference system, which will not be described in detail.

[0060] As an embodiment, when a resident moves out, an employee resigns, a visitor's visit ends, or a meeting ends, the relevant data needs to be updated, for example, the relevant data is directly deleted to reduce the total amount of cached data and improve the retrieval speed, or the relevant data is marked as expired data to retain historical records for subsequent archiving and query, etc. Specifically, after the data changes in the above information system, the changed content can be pushed to the identity recognition device 101, or first pushed to the above external server and then pushed to the identity recognition device 101 by the external server; or the identity recognition device 101 or the external server can periodically update the locally stored data, request to call and obtain data from the above information system, etc., which is not limited in this embodiment.

[0061] It should be noted that the above-mentioned system can utilize existing information systems to save data acquisition costs. The above-mentioned employee information system and conference system are merely exemplary names. The names of actual existing systems may be different from the given examples. For example, the employee information system may be called a human resources database system, etc. The functions of actual existing systems may include the functions of multiple systems in the above-mentioned embodiments or partial functions of a certain system. For example, in addition to the contents recorded in the above-mentioned employee information system, the human resources database system may also include the contents recorded in the above-mentioned conference system, etc. This embodiment does not limit this.

[0062] Among them, the above-mentioned devices, servers, and systems can communicate with each other by means of network interfaces or serial interfaces, for example, RJ45 (a network card interface), wireless 4G (fourth-generation mobile communication technology), wireless 5G (fifth-generation mobile communication), RS232 (a serial communication interface), RS485 (another serial communication interface), etc., which are not limited in this embodiment.

[0063] The floor decision device 102 is deployed in the elevator car and is used to receive the above-mentioned associated floor information, determine the target floor of the elevator operation based on the associated floor information, and send an operation instruction for indicating the target floor of the elevator operation to the elevator controller, so that the elevator controller automatically lights up the target floor button indicator light corresponding to the target floor on the elevator button panel deployed in the above-mentioned elevator car and controls the elevator to open the elevator car when it runs to the target floor.

[0064] In this embodiment, after receiving the associated floor information corresponding to the target user characteristics, the floor decision device 102 selects the target floor from the associated floor information and controls the elevator to run to the target floor. The specific implementation method is that the floor decision device 102 sends an operation instruction to the elevator controller in the elevator, and the operation instruction includes at least relevant information of the target floor. The elevator controller automatically lights up the target floor button indicator corresponding to the target floor on the elevator button panel, and controls the elevator to click and drive the elevator to the corresponding target floor. When running to the target floor, the elevator car is opened. In this embodiment, determining the target floor according to the associated floor information can be implemented in a variety of ways. This embodiment does not limit the specific implementation method. Some implementation methods will be given as examples below.

[0065] As an embodiment, it can be required that in the correspondence between the above-mentioned stored user characteristics and floor information, the user characteristics of each user correspond to only one floor information, and the floor in the above-mentioned associated floor information is the target floor; a certain floor can be designated as having a higher priority in the corresponding multiple floor information, and the floor decision device 102 will select this floor as the target floor by default; it is also possible to select the floor that the user most frequently visits as the target floor in the corresponding multiple floor information based on the elevator usage record of the target user in the historical time; it is also possible to perform a voice prompt to prompt the user to manually select the target floor after detecting that the associated floor information contains multiple floor information, and automatically trigger the target floor button when it is detected that the associated floor information contains only one floor information, and the present embodiment does not limit this.

[0066] Optionally, as an embodiment, the elevator button panel deployed in the elevator car can be as follows Figure 2As shown, it includes: a key panel 200, a current floor display screen 201, a door opening key 202, a door closing key 203, and floor keys (including indicator lights) 204-211. For example, when the floor decision device 102 determines that the target floor is the fifth floor according to the associated floor information, it sends an operation instruction to the elevator controller, and the operation instruction includes the information that the target floor is the fifth floor. Then, the elevator controller automatically lights up the indicator light of the floor key 208 corresponding to the target floor fifth floor on the key panel 200, controls the elevator to run to the target floor and opens the elevator car, instead of the process of the user manually pressing the floor key 208.

[0067] Preferably, as an embodiment, the floor decision device 102 can also issue instructions to the elevator controller, or the elevator controller can independently decide that when the indicator light of the floor button 208 is lit, the door closing button 203 is triggered to close the elevator car door, thereby shortening the door closing waiting time without user contact and improving the operating efficiency of the elevator.

[0068] As an embodiment, different operation modes can be set for the floor decision device 102, and the corresponding operation mode can be automatically switched according to the preset schedule and the current time, or the current operation mode can be switched to the operation mode indicated by the external instruction according to the received external instruction, etc. The operation mode can include a working mode, a meal mode, a rest mode, a night mode, a shutdown mode, etc.

[0069] As an embodiment, when the above-mentioned associated floor information contains information of multiple floors, the floor decision device 102 identifies the current operating mode, and determines the target floor of the elevator operation from the associated floor information in combination with the current operating mode. For example, when the current operating mode is the off-duty mode, the floor where the garage is located is selected as the target floor; when the current operating mode is the meal mode, the floor where the cafeteria is located is selected as the target floor, and so on.

[0070] Optionally, for example, according to the corresponding table of operation modes for each time period as shown in Table 1, the floor decision device 102 may determine the current operation mode according to the current time.

[0071] Time period Current operating mode Mode Information 20:30-8:29 Idle mode Some elevators will be shut down; all floors will be open 8:30-9:29 Breakfast operation mode Open some floors 9:30-11:49 Morning work mode Open all floors; link conference system 11:50-12:39 Lunch operation mode Open some floors 12:40-13:19 Lunch break operation mode Open some floors 13:20-17:29 Afternoon work mode Open all floors; link conference system 17:30-18:19 Dinner and after get off work mode Open some floors; 18:20-20:29 Night overtime mode Open all floors; link conference system

[0072] Table 1

[0073] As an embodiment, the current time is 8:00, and an employee arrives at the elevator entrance where the above-mentioned contactless elevator control system is installed. The floor decision device 102 in the elevator is currently in the idle operation mode and is not stopped, and all floors are open. When the elevator car door is opened, the employee enters the elevator, and the identity recognition device 101 recognizes the identity characteristics of the employee, and combines the identity characteristics and floor information corresponding to the identity characteristics obtained from the employee information system and pushed to the identity recognition device 101 by the external server to determine the employee's associated floor information and push it to the floor decision device 102; the floor decision device 102 determines that the current working mode is the idle operation mode according to the current time period, and all floors can be opened during the non-peak operation period. The associated floor information shows that the employee's office is on the seventh floor, so the floor decision device 102 determines that the target floor is the seventh floor and informs the elevator controller through instructions. The elevator controller responds to the instruction, automatically lights up the button indicator corresponding to the seventh floor, starts the elevator and runs to the seventh floor.

[0074] As an embodiment, the current time is 8:30, and the above employee arrives at the elevator entrance of the elevator. After the employee enters the elevator, based on the same process, the floor decision device 102 obtains the employee's associated floor information; the floor decision device 102 determines that the current working mode is the breakfast operation mode according to the current time period, which belongs to the peak period of elevator operation, and only some floors are allowed to be open, and the dining floor is selected first. The associated floor information shows that the employee's canteen is located on the third floor, so the floor decision device 102 determines that the target floor is the third floor and informs the elevator controller through instructions. The elevator controller responds to the instructions and automatically lights up the button indicator corresponding to the third floor. If the employee needs to go to the third floor for dining at this time, the elevator controller has automatically selected the floor for him, and the employee does not need to operate the elevator floor button; but if the actual target floor of the employee at this time is not the third floor, he needs to cancel the selection of the floor and manually select other floors to go to. Optionally, if the floor selected by the employee is a floor open for operation during this time period, the elevator will send him to the floor selected by the employee; otherwise, the elevator can issue a warning and prompt him to reselect the floor.

[0075] As an example, the current time is 9:35, and the employee arrives at the elevator entrance. After the employee enters the elevator, based on the same process, the floor decision device 102 obtains the employee's associated floor information; the floor decision device 102 determines that the current working mode is the morning working mode according to the current time period, and all floors can be opened, and the associated floor information shows that the employee has a meeting on the tenth floor of this building from 9:40 to 11:30, so the floor decision device 102 determines that the target floor is the tenth floor and informs the elevator controller through an instruction. The elevator controller responds to the instruction, automatically lights up the button indicator corresponding to the tenth floor, starts the elevator and runs to the seventh floor.

[0076] Optionally, as an embodiment, the floor decision device 102 may include the following modules: a communication module, an elevator control algorithm module, a clock calendar module, an operation mode recording module, an alarm module, and the like.

[0077] Among them, the communication module is used for the communication between the floor decision device 102 and other devices, for example, communicating with the identity recognition device 101 or the elevator controller through a network interface or a serial interface; the elevator control algorithm module is used to determine the target floor based on a preset algorithm or rule, by combining the associated floor information with other acquired information; the clock calendar module is used to determine the current actual date and time, which is generally a battery-protected, long-term clock calendar chip. The initial date and clock are set by the maintenance personnel when the equipment is installed, and the maintenance personnel can also regularly calibrate the date or time during the use of the equipment; the operation mode recording module is used to record the operation mode of the elevator, including the operation mode automatically determined based on the current time or the operation mode set by the maintenance personnel; the alarm module is used to issue corresponding voice prompts, voice warnings, buzzer warnings, etc. according to the algorithm results or the elevator status, and can be configured according to actual needs.

[0078] So far, completed Figure 1 Description of the system shown.

[0079] pass Figure 1 It can be seen from the system shown that in this embodiment, by deploying an identity recognition device and a floor decision device in the elevator car, combined with the stored identity features and floor information, the target floor that the user entering the car needs to go to is determined based on identity recognition, and the floor decision device automatically controls the elevator controller to light up the elevator button corresponding to the target floor, and takes the user to the target floor. This realizes the user's contactless control of the elevator operation, avoids the problem of bacteria and viruses being left behind or contaminated when the user touches the button, reduces the risk of cross infection, and is conducive to the prevention and control of the epidemic.

[0080] In addition, by automatically selecting a target floor for the user and automatically controlling the elevator car door to close after the target floor is selected, there is no need to wait for the user to select the target floor button which may be slow and wait for the user to press the car door closing button, thereby shortening the waiting delay time of the elevator and improving the operating efficiency of the elevator.

[0081] Compared with other elevator control systems in the prior art, the contactless elevator control system provided by the present application does not require each user to install an elevator control APP (Application) on their mobile phone, nor does it require the issuance of an IC (Integrated Circuit Card) card to the user. At the same time, if necessary, the user is allowed to operate the elevator by pressing buttons as if taking an elevator without the present system installed, so as to avoid the inconvenience caused by the user being unable to use the elevator normally due to failure to obtain identity features or failure to determine the target floor.

[0082] Based on the same concept, the embodiment of the present application provides a contactless elevator control method based on identity recognition. Figure 3 1 is a processing flow chart of a contactless elevator control method based on identity recognition according to an exemplary embodiment, the method comprising:

[0083] Step 301, identifying the target identity characteristics of the target user entering the elevator car through an identity recognition device;

[0084] Step 302: the identity recognition device searches for the associated floor information corresponding to the target identity feature in the stored correspondence between the identity feature and the floor information, or sends the acquired target identity feature to an external server, and the external server searches for the associated floor information corresponding to the target identity feature in the stored correspondence between the identity feature and the floor information, and the identity recognition device receives the associated floor information returned by the external server and pushes the associated floor information to the floor decision device;

[0085] Step 303, the floor decision device receives the associated floor information, determines the target floor of the elevator according to the associated floor information, and sends an operation instruction for indicating the target floor of the elevator to the elevator controller, so that the elevator controller automatically lights up the target floor button indicator light corresponding to the target floor on the elevator button panel deployed in the elevator car and controls the elevator to open the elevator car when it runs to the target floor.

[0086] It is understandable that the contactless elevator control method provided in the embodiment of the present application corresponds to the above-mentioned contactless elevator control system. The specific content can refer to the contents of each embodiment of the contactless elevator control system, which will not be repeated here.

[0092] Optionally, in this embodiment, when the elevator car door is opened, the elevator controller notifies the identity recognition device 101 to start; in addition, other methods can also be used to ensure that the identity recognition device 101 is in operation when a user may enter the elevator car, such as keeping the identity recognition device 101 in a long-term operation state.

[0093] Step 403, identifying the user identity characteristics and determining the associated floor information;

[0094] As an embodiment, the identity recognition device 101 recognizes a user entering the elevator, obtains the identity characteristics of the user, and determines the associated floor information of the user based on the correspondence between the user identity characteristics and the floor information stored locally. The above correspondence stored locally can be obtained regularly from the user information system by an external server and pushed to the identity recognition device 101, or can be obtained by other means, which is not limited in this embodiment.

[0095] Step 404, pushing the associated floor information to the floor decision device 102;

[0096] As an embodiment, after the identity recognition device 101 determines the associated floor information of the user, the associated floor information is pushed to the floor decision device 102, and the floor decision device 102 receives the associated floor information of the user.

[0097] Step 405, obtaining the current operation mode and determining the target floor;

[0098] As an embodiment, the floor decision device 102 obtains the current operation mode, and then determines the target floor of the user from the associated floor information according to the current operation mode. The specific determination method has been exemplified in the above embodiment and will not be repeated here.

[0099] Step 406, informing the target floor by command;

[0100] As an embodiment, after the floor decision device 102 determines the target floor of the user, it sends an instruction to the elevator controller, and the instruction includes the target floor.

[0101] Step 407, light up the button corresponding to the target floor, close the car door, and control the elevator to run to the target floor;

[0102] As an embodiment, after receiving the instruction sent by the controller, the elevator controller lights up the elevator button corresponding to the target floor, drives the motor to control the car door to close and carry the user to the target floor, thereby realizing the user's contactless control of the elevator.

[0103] Preferably, in the case where multiple users enter the elevator car, the above process can be referred to for parallel processing, and the car door can be closed only after the target floor of each user has been determined and the button has been lit; the above process can also be referred to for processing each user in turn. For example, after the target floor of the previous user is determined and notified to the elevator controller by the floor decision device 102, the identity recognition device 101 determines whether there are any users in the elevator car whose target floor has not been determined. If so, step 403 is entered, and the same process is repeated until there are no users in the car whose target floor has not been determined, and the car door is closed at this time.
