Description

Technical Field

[0001] This invention relates to the field of elevator control technology, specifically to an elevator control method and system based on dual-dimensional cross-arbitration. Background Technology

[0002] With the development of artificial intelligence and Internet of Things technologies, contactless elevator access methods (such as facial recognition, voiceprint recognition, and fingerprint recognition) are gradually replacing traditional button operations to improve hygiene, safety, and convenience.

[0003] However, existing intelligent elevator systems still have the following technical shortcomings:

[0004] (1) Static binding limits flexibility. Currently, the mainstream facial recognition elevator access solution requires passengers to pre-bind a fixed floor. When passengers go to an unbound floor (such as when a visitor temporarily changes their destination), the system cannot respond, which means that the seamless elevator access method can only be used in limited scenarios.

[0005] (2) Multimodal conflicts lead to authentication failure. When the elevator system receives multiple biometric signals (such as face + voiceprint) at the same time, the existing technology lacks an effective arbitration mechanism, which may lead to the erroneous execution of low-priority instructions.

[0006] (3) Lack of hierarchical access control affects critical passage. In special places such as hospitals and government buildings, ordinary passengers may often occupy elevator resources, making it impossible to guarantee the priority of specific personnel (such as emergency doctors and VIP visitors) and reducing emergency passage efficiency.

[0007] Therefore, there is an urgent need for a more flexible elevator response solution that can be combined with a signal conflict arbitration mechanism. Summary of the Invention

[0008] To overcome the defects and shortcomings of existing technologies, this invention provides an elevator control method and system based on dual-dimensional cross-arbitration. By identifying biometric information and combining it with a dual-dimensional cross-arbitration strategy, this invention achieves a more flexible priority response to biometrics, dynamically adjusting and covering static binding, thus realizing a truly contactless elevator and improving the flexibility and safety of elevator use.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] This invention provides an elevator control method based on two-dimensional cross-arbitration, comprising the following steps:

[0011] During the pre-registration phase, the biometric data of passengers will be logically linked to their destination.

[0012] Establish a priority sequence for biometrics, assign a corresponding biometric modality score to each biometric priority, and do not bind the highest priority biometrics to a fixed target layer;

[0013] Establish a passenger class priority sequence and assign a corresponding passenger class score to each passenger class priority.

[0014] It receives elevator access commands from at least one passenger and assigns a dynamically calculated comprehensive priority index to each elevator access command. The comprehensive priority index is the product of the biometric modality score and the passenger class score.

[0015] Based on preset execution rules, elevator access commands with different comprehensive priority indices are executed, with priority given to elevator access commands with higher comprehensive priority index values ​​or earlier timestamps.

[0016] When a control command corresponding to the highest priority biometric is received, the control command corresponding to the highest priority biometric of the same passenger overrides the destination layer associated with its other biometrics, updates the destination layer, and responds to the floor corresponding to the highest priority biometric control command.

[0017] As a preferred technical solution, the priority sequence of biometric features is established, and the priority of each biometric feature is as follows: voiceprint, fingerprint, palm print, and face. The voiceprint feature is not bound to a fixed target layer.

[0018] As a preferred technical solution, the highest priority biometric feature is voiceprint feature. When a voice control command is received, the keywords contained in the voiceprint are identified, and the identity of the voice command issuer is verified by voiceprint comparison. If it is a registered passenger, it is checked whether there are other passengers in the car who need to go to the passenger's pre-registered destination floor. If there are, the original destination floor is retained and the command floor is added. If not, the destination floors associated with the passenger's other biometric features are overwritten, that is, the passenger's pre-registered destination floor is deleted, and the voice command floor is responded to.

[0019] As a preferred technical solution, when executing elevator commands with different comprehensive priority indices based on preset execution rules, a comprehensive priority index determination step is also included, specifically:

[0020] A preset comprehensive priority index threshold is established. The comprehensive priority index is compared with the comprehensive priority index threshold, and a dedicated elevator is assigned to passengers whose comprehensive priority index exceeds the preset comprehensive priority index threshold.

[0021] And when it is determined that the elevator car has reached full capacity, the elevator access instructions for passengers whose comprehensive priority index is lower than the comprehensive priority index threshold will be interrupted.

[0022] As a preferred technical solution, the step of updating the target layer also includes a lead-layer response step, specifically including:

[0023] Based on the elevator's current real-time speed and acceleration, the braking distance is calculated and expressed as:

[0024]

[0025] Where a is the braking deceleration;

[0026] The floor in the direction of elevator travel that corresponds to the minimum height difference between the current floor and the elevator's current floor that is greater than the braking distance will be designated as the leading floor.

[0027] During elevator operation, only requests to change the destination floor for the current floor ahead and subsequent floors are accepted and responded to.

[0028] The present invention also provides an elevator control system based on dual-dimensional cross-arbitration, comprising: a biometric pre-registration module, a biometric priority sequence construction module, a passenger level priority sequence construction module, a comprehensive priority index construction module, a cross-arbitration module, and a dynamic response module;

[0029] The biometric pre-registration module is used to establish a logical association between the acquired passenger biometrics and the destination layer during the pre-registration stage;

[0030] The biometric priority sequence construction module is used to establish a priority sequence of biometrics, assign a corresponding biometric modality score to the priority of each biometric, and the highest priority biometric is not bound to a fixed target layer.

[0031] The passenger level priority sequence construction module is used to establish a passenger level priority sequence and assign a corresponding passenger level score to each passenger level priority.

[0032] The comprehensive priority index construction module is used to assign a dynamically calculated comprehensive priority index to each elevator ride command. The comprehensive priority index is the product of the biometric modality score and the passenger level score.

[0033] The cross-arbitration module is used to execute elevator access instructions with different comprehensive priority indices based on preset execution rules, and to prioritize the execution of elevator access instructions with higher comprehensive priority index values ​​or earlier timestamps.

[0034] The dynamic response module is used to overwrite the target layer associated with other biometrics of the same passenger with the control command corresponding to the highest priority biometric feature, update the target layer, and respond to the floor corresponding to the highest priority biometric control command.

[0035] As a preferred technical solution, the biometric priority sequence construction module is used to establish a priority sequence of biometrics, with the priority of each biometric being as follows: voiceprint, fingerprint, palmprint, and face. Voiceprint features are not bound to a fixed target layer.

[0036] As a preferred technical solution, the highest priority biometric feature is voiceprint feature. When a voice control command is received, the keywords contained in the voiceprint are identified, and the identity of the voice command issuer is verified by voiceprint comparison. If it is a registered passenger, it is checked whether there are other passengers in the car who need to go to the passenger's pre-registered destination floor. If there are, the original destination floor is retained and the command floor is added. If not, the destination floors associated with the passenger's other biometric features are overwritten, that is, the passenger's pre-registered destination floor is deleted, and the voice command floor is responded to.

[0037] As a preferred technical solution, it also includes a comprehensive priority index judgment module, used to perform a comprehensive priority index judgment step when executing elevator access instructions with different comprehensive priority indices based on preset execution rules, specifically including:

[0038] A preset comprehensive priority index threshold is established. The comprehensive priority index is compared with the comprehensive priority index threshold, and a dedicated elevator is assigned to passengers whose comprehensive priority index exceeds the preset comprehensive priority index threshold.

[0039] And when it is determined that the elevator car has reached full capacity, the elevator access instructions for passengers whose comprehensive priority index is lower than the comprehensive priority index threshold will be interrupted.

[0040] As a preferred technical solution, it also includes a lead-ahead response module, used to execute the lead-ahead response in the step of updating the target layer, specifically including:

[0041] Based on the elevator's current real-time speed and acceleration, the braking distance is calculated and expressed as:

[0042]

[0043] Where a is the braking deceleration;

[0044] The floor in the direction of elevator travel that corresponds to the minimum height difference between the current floor and the elevator's current floor that is greater than the braking distance will be designated as the leading floor.

[0045] During elevator operation, only requests to change the destination floor for the current floor ahead and subsequent floors are accepted and responded to.

[0046] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0047] (1) In the existing contactless elevator control, only a specific floor or multiple floors can be preset to respond. When the passenger’s destination floor is not the one originally set, the contactless elevator cannot achieve the purpose of calling the elevator, and the pre-registered floor cannot be changed temporarily. This invention combines a two-dimensional cross-arbitration strategy to solve the problem of rigid resource allocation caused by the existing technology relying on only a single dimension (such as the passenger’s VIP level). It also breaks through the static binding limitation, and the pre-registered floor can be changed and adjusted to dynamically respond to the elevator calling demand, thus realizing a truly contactless elevator calling and improving the flexibility and safety of elevator use.

[0048] (2) By matching multimodal biometrics with the destination floor of the elevator, the present invention enables passengers to independently select the destination floor of the elevator. Passengers can choose to use the corresponding multimodal biometrics to determine the floor to go to. Higher priority floors can directly cover lower priority floors without the need for cancellation, making the operation convenient and efficient.

[0049] (3) The present invention can be applied to the elevator needs of passengers in different scenarios. It can prioritize the elevator needs of passengers whose elevator needs exceed the set comprehensive priority index threshold, while the elevator needs of other levels of passengers will not be responded to, thus maximizing the elevator efficiency of passengers whose elevator needs exceed the set comprehensive priority index threshold.

[0050] (4) Based on the parallel recognition algorithm, the present invention can simultaneously process the elevator calling needs of multiple people based on multimodal biometrics, without the need for individual recognition, thereby enabling multiple people to call elevators at the same time, increasing the response range and improving the response speed. Attached Figure Description

[0051] Figure 1 This is a flowchart illustrating the elevator control method based on dual-dimensional cross-arbitration of the present invention. Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0053] Example 1

[0054] like Figure 1 As shown, this embodiment provides an elevator control method based on dual-dimensional cross-arbitration, including the following steps.

[0055] S1: Pre-register passenger biometrics and associate them with the destination layer;

[0056] S2: Establish a priority sequence for biometric features, with the highest priority biometric features not bound to a fixed target layer;

[0057] In this embodiment, the preferred priority of each biometric feature is: voiceprint > fingerprint > palmprint > face, and the voiceprint feature is not bound to a fixed target layer;

[0058] S3: Establish a passenger priority sequence: Level 1 > Level 2 > ... > Level n;

[0059] S4: Construct a two-dimensional cross-arbitration strategy. When multiple biometric features of multiple passengers are received simultaneously, execute the elevator access instruction for the corresponding destination floor according to the two-dimensional cross-arbitration strategy.

[0060] In this embodiment, the dual-dimensional cross-arbitration strategy is as follows: for any elevator access command received outside the car at any given time, the comprehensive priority index of each elevator access command is calculated. The comprehensive priority index is specifically expressed as follows:

[0061] Overall Priority Index = Biometric Modality Score × Passenger Class Score;

[0062] The score for passenger class n is: Sn = (N+1-n), where N is the highest class; the scores for biometric features are: voiceprint = 4 points, fingerprint = 3 points, palm print = 2 points, and face = 1 point;

[0063] In this embodiment, elevator commands with different comprehensive priority indices are executed according to preset execution rules. The elevator command with the highest comprehensive priority index is executed first, and other elevator commands with lower comprehensive priority indices are delayed. Service reminders can be given through voice and video, or the destination layer can be used to determine whether the elevator command has been responded to. When multiple requests have the same comprehensive priority index, the elevator command with the earlier timestamp is executed first.

[0064] In this embodiment, a comprehensive priority index threshold is also set, and dedicated elevators are allocated to passengers whose comprehensive priority index exceeds the set comprehensive priority index threshold. When the elevator car is full, the execution of instructions for passengers whose comprehensive priority index is below the set comprehensive priority index threshold is interrupted.

[0065] S5: When the highest priority biometric control command is received in the elevator car, the keywords of the control command are identified to obtain the target floor information. The floor dynamic coverage strategy in the elevator car is executed. The control command corresponding to the highest priority biometric of the same passenger covers the target floor bound to other biometrics of itself, the target floor is updated, and the floor corresponding to the highest priority biometric control command is responded to.

[0066] In this embodiment, the elevator only accepts and responds to destination floor change requests for the current leading floor and subsequent floors during operation. The leading floor is the nearest floor that the elevator can safely stop at in the direction of travel, and it is determined as follows:

[0067] Based on the elevator's current real-time speed v and real-time acceleration a, the braking distance d is calculated using the following formula:

[0068]

[0069] Where a is the braking deceleration, which is taken as a positive value;

[0070] The advance floor is the smallest floor that satisfies the condition that the floor height h is greater than or equal to the braking distance d, that is:

[0071] h≥d

[0072] The advanced floor is the nearest floor in the direction of elevator travel that meets this condition.

[0073] In this embodiment, the highest priority biometric feature is voiceprint feature. When a voice command is received in the elevator car, the target floor is determined by triggering the recognition of keywords contained in the voiceprint. The voiceprint dynamic coverage rule in the car is executed, and the identity of the voice command issuer is verified by voiceprint comparison. If it is a registered passenger, it is detected whether there are other passengers in the car who need to go to the passenger's pre-registered target floor. If so, the original target floor is retained and the command floor is added. If not, the target floor bound to the passenger's other biometric features is overwritten, that is, the passenger's pre-registered target floor is deleted, and the voice command floor is responded to.

[0074] In this embodiment, multiple voiceprint commands can be processed in parallel, and individual passengers can be identified through voiceprint separation technology;

[0075] The step numbers in this embodiment are only set for ease of explanation and do not impose any restrictions on the order of the steps. The execution order of each step in the embodiment can be adaptively adjusted according to the understanding of those skilled in the art.

[0090] Based on the elevator's current real-time speed and acceleration, the braking distance is calculated and expressed as:

[0091]

[0092] Where a is the braking deceleration;

[0093] The floor in the direction of elevator travel that corresponds to the minimum height difference between the current floor and the elevator's current floor that is greater than the braking distance will be designated as the leading floor.

[0094] During elevator operation, only requests to change the destination floor for the current floor ahead and subsequent floors are accepted and responded to.

[0095] To better aid in understanding the technical solution of this invention, several implementation scenarios are listed below:

[0096] Scenario 1:

[0097] S1: Passenger K is an employee of Company K. Their office is on the 12th floor and their laboratory is on the 15th floor. Passenger K's facial information is set to correspond to the destination floor 12, and their fingerprint information is set to correspond to the destination floor 15. Passenger K is a Level 2 person.

[0098] S2: Passenger K is going to work as usual. In the elevator lobby, the biometric recognition module recognizes passenger K's facial information, converts it into Level 2 passenger K, and identifies the passenger's need to take the elevator to the destination floor 12.

[0099] S3: In response to passenger K's request to take the elevator, passenger K enters the elevator car and successfully proceeds to the 12th floor.

[0100] Scenario 2:

[0101] Based on step S1 of scenario one, on a certain day, passenger K needs to go to the laboratory to work;

[0102] S2: Passenger K is going to work as usual. In the elevator lobby, the biometric recognition system recognizes passenger K's facial information. At the same time, passenger K enters his elevator information by fingerprint. The biometric recognition module recognizes passenger K's facial and fingerprint information at the same time. Through a two-dimensional cross-arbitration strategy, the fingerprint information with higher priority is converted into a level 2 passenger K's elevator request to go to the destination floor 15.

[0103] S3: In response to passenger K's request to take the elevator, passenger K enters the elevator car and successfully proceeds to the 15th floor.

[0104] Scenario 3:

[0105] Based on step S1 of scenario one, one day, passenger K wanted to have lunch in the cafeteria on the 3rd floor before going to work.

[0106] S2: Passenger K is going to work as usual. In the elevator lobby, the biometric recognition module recognizes passenger K's facial information, converts it into a Level 2 passenger K's elevator request to go to the destination floor 12, and transmits it to the elevator dispatcher.

[0107] S3: The elevator dispatcher responds to passenger K's elevator request. Passenger K enters the elevator car and enters the car. Inside the car, passenger K issues a voice command: "I want to go to the 3rd floor."

[0108] S4: The biometric recognition module recognizes voice commands and extracts voiceprint features, comparing them to determine that it is the same passenger and that there are no other passengers in the car;

[0109] S5: Eliminate passenger K's outbound call request registered through the biometric identification module for the 12th floor, and re-respond to the elevator request for the 3rd floor.

[0110] Scenario 4:

[0111] Based on step S1 in scenario one, on a certain day, an important client V visits the company. The information of the important client V is pre-entered, and his facial information corresponds to the destination floor 18. The important client V is a level 1 person. The company sets up a dedicated elevator for passengers with a comprehensive priority index ≥ N.

[0112] S2: Passenger K and important customer V are both waiting in the elevator lobby. The biometric recognition module simultaneously identifies the facial information of both passenger K and important customer V. The two-dimensional cross-arbitration strategy calculates the comprehensive priority index of important customer V as N. The elevator dispatcher allocates a dedicated elevator to important customer V, prioritizing the response to important customer V's elevator call request. This is converted into a Level 1 person important customer V's elevator request to go to the destination floor 18. The elevator can be reminded of the current floor via voice or video, or passenger boarding can be arranged through management means. Next, the elevator request of passenger K is responded to, converted into a Level 2 person passenger K's elevator request to go to the destination floor 12.

[0113] S3: In response to the elevator request of important customer V, important customer V entered the elevator car and successfully went to the 18th floor;

[0114] S4: The elevator master controller continues to respond to passenger K's elevator request and returns to pick up and drop off passenger K.

[0115] Scenario 5:

[0116] Based on steps S1 to S3 of scenario four;

[0117] S4: Passenger K and important customer V enter the elevator car together;

[0118] S5: Passenger K discovers that the elevator control has not registered the passenger's request to go to the 12th floor, and issues a voice command "I want to go to the 12th floor";

[0119] S6: The biometric module compares the passenger's voiceprint and finds that the passenger is not the same important customer K who entered the current elevator request. The original elevator request is maintained and no new elevator request is added. At this time, the button for the destination floor that passenger K wants to go to in the voice command will not light up, or the elevator's internal display screen will show that this elevator is going to the destination floor of important customer V.

[0120] Scenario Six:

[0121] Based on scenario four, a configuration of four group-controlled elevators is adopted. In this configuration, elevator master controller 1 responds to the elevator needs of important customer V, elevator master controller 2 responds to the elevator needs of passenger K, and the group-controlled elevators are equipped with external call displays that will show the corresponding destination floor information and allocate plans in advance.

[0122] Scenario 7:

[0123] Other application scenarios include "hospital emergency scenarios":

[0124] Nurse (Level 2) uses voiceprint to call out: "To the operating room" → Overall priority index = 4 × 2 = 8;

[0125] Chief Physician (Level 1), facial recognition registration back to office → Overall Priority Index = 1 × 3 = 3;

[0126] Execution: Prioritize sending nurses to the operating room (8>3). This scenario demonstrates the application value of cross-arbitration in emergency situations.

[0127] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
