Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to an elevator control method for preventing leakage of destination floor information of vulnerable passengers such as single women. Background Art

[0002] At present, elevators have become the main vertical transportation mode for people to move between floors of buildings, providing great convenience for people's daily life. However, for vulnerable passengers such as single women and minors who take elevators during sparse passenger flow periods such as nighttime, there may be unsafe factors when taking elevators. In order to improve the safety of these vulnerable passengers, the existing technology provides a variety of solutions.

[0003] The elevator control device proposed in Document 1 (CN201580085261.0) automatically analyzes the gender of the user when riding the elevator, and enters the prevention operation mode when there is one female and one male. All users register their destination floors one by one. When registering the destination floor, the user and the destination floor are associated according to each user. When the car reaches the female's destination floor, the female gets off the elevator first, and after the female completes getting off the elevator, the door is temporarily closed completely. After the door is completely closed, the door is fully opened again after a specified time interval, and the male gets off the elevator. This solution essentially prevents women from being followed by men by ensuring that there is a specified time interval between the female passenger who gets off the elevator first and the male passenger who gets off the elevator later. It solves the problem of women being followed after getting off the elevator.

[0004] Document 2 (CN201780089528.2) proposes that in the preventive operation device of the elevator, when it is detected that a person is riding alone and the elevator call is registered and the door closing action starts, when a person enters the first area, the walking speed of the person is measured, and when the walking speed is detected to be higher than the speed of detecting abnormality, an output signal for controlling the door closing speed to a first speed faster than the normal speed is generated, and the first area is set to surround the second area set adjacent to the car door and is larger than the second area. When the person enters the second area, the walking speed of the person is measured, and when the walking speed is detected to be higher than the speed of detecting abnormality, an output signal for controlling the door closing speed to a second speed faster than the first speed is generated. This scheme is essentially to prevent vulnerable passengers from riding the elevator with a potentially dangerous trailing passenger by accelerating the door closing when a suspicious person appears adjacent to the car door, thereby improving the elevator safety of vulnerable passengers, and it solves the safety problem of vulnerable passengers sharing the same elevator with trailing passengers.

[0005] The elevator prevention system provided by Document 3 (CN201780095200.1) is equipped with an autonomous mobile robot that can get on and off the elevator car and move autonomously, and is equipped with: a detection unit that detects the identification information of the elevator user; and a suspicious person determination unit that determines whether the elevator user is a suspicious person based on the identification information detected by the detection unit. When a suspicious person determined by the suspicious person determination unit and a regular passenger determined by the suspicious person determination unit as not a suspicious person are riding in the elevator car together, the autonomous mobile robot is moved between the suspicious person and the regular passenger in the elevator car. This solution essentially uses robots to separate suspicious persons from regular passengers, thereby improving the safety of regular passengers riding the elevator. It solves the safety problem when regular passengers and suspicious persons share the same elevator.

[0006] The nighttime prevention method of the elevator proposed in Document 4 (CN202410239750.8) is as follows: when receiving an external call command, obtain the external call floor corresponding to the external call command; determine whether the current time is within the preset prevention time range, and determine whether the external call floor is the preset prevention floor; if so, allocate the elevator to respond to the external call command to reach the external call floor; receive the button command of the current passenger through the internal call button in the elevator, and obtain the destination floor corresponding to the button command; determine whether the destination floor is a non-prevention floor; if so, switch the elevator to the nighttime prevention mode, in which the elevator only responds to the button command of the internal call button in the elevator, and cancels the display of the external call display board of the elevator; after the elevator responds to the button command to reach the destination floor, determine whether the current passenger has left the elevator; if so, after the elevator runs to a random floor, switch the elevator to normal mode. This solution essentially prevents the destination floor information of vulnerable passengers from being known by passengers waiting for the elevator at the floor station through the display of the elevator external call display board (for the stop floor information of the elevator car), which solves the risk of leakage of the destination floor information of vulnerable passengers. Although this solution can reduce the risk of leakage of destination information of vulnerable passengers to a certain extent, there is still room for further improvement.

[0007] Therefore, how to further reduce the risk of leakage of destination information of vulnerable passengers becomes an unsolved technical problem. Summary of the invention

[0008] The technical problem to be solved by the present invention is how to further reduce the risk of leakage of the destination layer information of vulnerable passengers.

[0009] In order to solve the above technical problems, the present invention discloses an elevator control method for preventing leakage of destination floor information of vulnerable passengers, comprising:

[0010] Step 1: Determine whether a vulnerable passenger is detected entering the elevator car. If so, proceed to the next step. Otherwise, control the elevator to respond to the passenger's elevator demand in a normal mode, and end;

[0011] Step 2: determine whether there is a first suspicious passenger in the elevator car before the vulnerable passenger enters the elevator car. If so, receive and hide the destination floor registration information of the vulnerable passenger, and proceed to a step that is after and adjacent to step 4. Otherwise, receive the destination floor registration information of the vulnerable passenger and proceed to the next step.

[0012] Step 3: Determine whether there is a second suspicious passenger following the vulnerable passenger into the elevator car after the vulnerable passenger enters the elevator car. If so, hide the destination floor information of the vulnerable passenger before the second suspicious passenger enters the car and proceed to the next step; otherwise, proceed directly to the next step;

[0013] Step 4, receiving the destination floor information of the second suspicious passenger;

[0014] Step 5: Control the elevator to stop at each destination floor of the suspicious passengers until there are no more suspicious passengers in the car;

[0015] Step 6, controlling the elevator to stop at the destination floor of the vulnerable passenger;

[0016] Step 7. End.

[0017] Preferably, between step 5 and step 6, the method further includes: step A1, canceling the elevator's response to the landing call signal that causes the elevator to stop before reaching the vulnerable passenger's destination floor.

[0018] Preferably, before step 6 and adjacent to step 6 and / or after step 6 and adjacent to step 6, the method further includes: step A2, controlling the elevator to stop at at least one floor.

[0019] Preferably, when the step A2 is located after the step 6 and adjacent to the step 6, the step A2 controls the elevator to finally stop at the decentralized standby floor of the elevator.

[0020] Preferably, after step 5 and adjacent to step 5, the following includes: step A3, canceling the floor station device providing elevator car position information to passengers waiting for the elevator; and before step 7 and adjacent to step 7, the following includes: step A4, restoring the floor station device providing elevator car position information to passengers waiting for the elevator.

[0021] Preferably, step A3 only cancels the floor station device located at the suspicious passenger's destination floor and / or the vulnerable passenger's departure floor from providing the elevator car position information to the waiting passengers; step A4 only restores the floor station device located at the suspicious passenger's destination floor and / or the vulnerable passenger's departure floor from providing the elevator car position information to the waiting passengers.

[0022] Preferably, only when no suspicious passenger enters the elevator car at the departure floor of the vulnerable passenger and rides the elevator with the vulnerable passenger, step A3 cancels the landing device located at the departure floor of the vulnerable passenger to provide the elevator car position information to the waiting passengers.

[0023] The present invention also provides an elevator control method for preventing leakage of destination floor information of vulnerable passengers, the control method comprising:

[0024] Step S1: determine whether a vulnerable passenger is detected entering the elevator car. If so, proceed to the next step. Otherwise, control the elevator to respond to the passenger's elevator demand in a normal mode, and end;

[0025] Step S2, determining whether there is a first suspicious passenger in the elevator car before the vulnerable passenger enters the elevator car, if so, refusing to receive the destination floor registration information of the vulnerable passenger and proceeding to the next step, otherwise directly proceeding to the next step;

[0026] Step S3, determining whether there is a second suspicious passenger following the vulnerable passenger into the elevator car after the vulnerable passenger enters the elevator car, if so, receiving the destination floor information of the second suspicious passenger and proceeding to the next step, otherwise directly proceeding to the next step;

[0027] Step S4, controlling the elevator to stop at each destination floor of the suspicious passengers until there are no more suspicious passengers in the car;

[0028] Step S5, recovering and receiving the destination layer information of the vulnerable passengers;

[0029] Step S6, controlling the elevator to stop at the destination floor of the vulnerable passenger;

[0030] Step S7, end.

[0031] Preferably, between step S5 and step S6, the method further includes: step SB1, canceling the elevator's response to the landing call signal that causes the elevator to stop before reaching the vulnerable passenger's destination floor.

[0032] Preferably, before the step S6 and adjacent to the step S6 and / or after the step S6 and adjacent to the step S6, the method further includes: step SB2, controlling the elevator to randomly stop at at least one floor.

[0033] Preferably, when the step SB2 is located after the step S6 and adjacent to the step S6, the step SB2 controls the elevator to finally stop at the decentralized standby floor of the elevator.

[0034] Preferably, between step S4 and step S6, it also includes: step SB3, canceling the floor station device providing the elevator car position information to the waiting passengers; before step S7 and adjacent to step S7, it also includes: step SB4, restoring the floor station device providing the elevator car position information to the waiting passengers.

[0035] Preferably, the step SB3 only cancels the floor devices located at the suspicious passenger's destination floor and / or the vulnerable passenger's departure floor from providing the elevator car position information to the waiting passengers.

[0036] Preferably, step SB3 cancels the floor device located at the vulnerable passenger's departure floor from providing the elevator car location information to the waiting passengers only when no suspicious passenger enters the elevator car at the vulnerable passenger's departure floor and rides the elevator with the vulnerable passenger.

[0037] The present invention also provides an elevator control method for preventing leakage of departure floor information of vulnerable passengers, the control method comprising:

[0038] Step T1, receiving a passenger elevator call signal;

[0039] Step T2: determine whether the elevator call signal comes from a vulnerable passenger. If so, proceed to the next step. Otherwise, control the elevator to respond to the passenger's elevator call signal in a normal mode, and end;

[0040] Step T3: determine whether there is a suspicious passenger in the elevator before the elevator arrives at the departure floor of the vulnerable passenger. If so, proceed to the next step; otherwise, control the elevator to respond to the passenger's elevator call signal in a normal mode, and end;

[0041] Step T4: Ignore the elevator call signal of the vulnerable passenger and transport the suspicious passenger, and return to step T3.

[0042] Preferably, between step T2 and step T3, the following is further included: step C1, determining whether the current running direction of the elevator is consistent with the expected riding direction of the vulnerable passenger, if so, proceeding to the next step, otherwise waiting until the elevator runs in the reverse direction.

[0043] Preferably, when there is a suspicious passenger in the car who will not get off before the elevator stops at the departure floor of the vulnerable passenger in response to the call signal of the vulnerable passenger, the step T3 determines that there is a suspicious passenger in the car.

[0044] Preferably, when the destination floor of the suspicious passenger is located ahead of the departure floor of the vulnerable passenger relative to the elevator running direction, the step T3 determines that the suspicious passenger will not get off the elevator before the departure floor of the vulnerable passenger.

[0045] Preferably, when at least one of the following conditions is met, the step T3 determines that there is no suspicious passenger in the car when the elevator arrives and stops at the vulnerable passenger departure floor:

[0046] Condition 1: The destination floors of all suspicious passengers in the car are between the current floor of the elevator car and the departure floor of the vulnerable passengers, and there is no elevator call signal from suspicious passengers whose departure floor is between the current floor of the elevator car and the departure floor of the vulnerable passengers;

[0047] Condition 2: There is no suspicious passenger in the current car and there is no elevator call signal from a suspicious passenger whose departure floor is between the current floor of the elevator and the departure floor of the vulnerable passenger.

[0048] Beneficial technical effects

[0049] The elevator control method for preventing leakage of destination or departure floor information of vulnerable passengers of the present invention can comprehensively and maximally reduce the risk of leakage of destination or departure floor information of vulnerable passengers.

[0058] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only an embodiment of a part of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention. It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence.

[0059] Example 1

[0060] like Figure 1 As shown, the elevator control method for preventing leakage of destination floor information of vulnerable passengers in this embodiment includes the following steps:

[0061] Step 1: Determine whether a vulnerable passenger is detected entering the elevator car. If so, proceed to the next step. Otherwise, control the elevator to respond to the passenger's elevator demand in a normal mode, and end;

[0062] Step 2: determine whether there is a first suspicious passenger in the elevator car before the vulnerable passenger enters the elevator car. If yes, receive and hide the destination floor registration information of the vulnerable passenger, and proceed to the step after and adjacent to step 4 (step 5 in this embodiment); otherwise, receive the destination floor registration information of the vulnerable passenger and proceed to the next step;

[0063] Step 3: Determine whether there is a second suspicious passenger following the vulnerable passenger into the elevator car after the vulnerable passenger enters the elevator car. If so, hide the destination floor information of the vulnerable passenger before the second suspicious passenger enters the car and proceed to the next step; otherwise, proceed directly to the next step;

[0064] Step 4, receiving the destination floor information of the second suspicious passenger;

[0065] Step 5: Control the elevator to stop at each destination floor of the suspicious passengers until there are no more suspicious passengers in the car;

[0066] Step 6, controlling the elevator to stop at the destination floor of the vulnerable passenger;

[0067] Step 7. End.

[0068] In this embodiment, the identification of vulnerable passengers can be carried out by obtaining the identity information of the passenger (such as by swiping a card, collecting the passenger's biometrics, etc.) and determining the passenger as a vulnerable passenger based on the passenger's identity information, or by using an image captured by a camera installed in the elevator lobby or in the elevator car to determine the passenger as a vulnerable passenger through image recognition. This embodiment does not impose any restrictions on how to determine vulnerable passengers, nor does it impose any restrictions on what kind of passengers can be considered vulnerable passengers. Vulnerable passengers can be any passengers who do not want the destination floor information to be leaked.

[0069] Likewise, this embodiment does not impose any restrictions on the identification and definition of suspicious passengers (including the first suspicious passenger and the second suspicious passenger). Any passenger who may have any bad intentions towards vulnerable passengers or do anything that is not conducive to vulnerable passengers can be regarded as a suspicious passenger.

[0070] This embodiment adopts means 1, i.e., receiving and hiding the destination floor registration information of the vulnerable passenger when there is a first suspicious passenger in the elevator car before the vulnerable passenger enters the elevator car, thereby eliminating the possibility that the destination floor information of the vulnerable passenger may be obtained by the first suspicious passenger, thereby reducing the risk of leakage of the destination floor information of the vulnerable passenger.

[0071] This embodiment adopts method 2 when a second suspicious passenger follows the vulnerable passenger into the elevator car. That is, it hides the destination floor information of the vulnerable passenger before the second suspicious passenger enters the car. This eliminates the possibility that the destination floor information of the vulnerable passenger may be obtained by the second suspicious passenger, thereby reducing the risk of leakage of the destination floor information of the vulnerable passenger.

[0072] Obviously, this embodiment eliminates the risk of the vulnerable passenger's destination floor information being leaked to suspicious passengers who share the same elevator with the vulnerable passenger while the vulnerable passenger is in the elevator car by adopting the above two technical means.

[0073] Example 2

[0074] This embodiment further defines and explains the embodiment 1.

[0075] like Figure 2 As shown, the elevator control method for preventing leakage of destination floor information of vulnerable passengers in this embodiment further includes between step 5 and step 6:

[0076] Step A1, canceling the elevator's response to the landing call signal that causes it to stop before reaching the vulnerable passenger's destination floor.

[0077] The purpose of adding step A1 is to:

[0078] 1) Eliminate the possibility that the vulnerable passengers’ destination floor information is known by the waiting passengers at the landing who enter the car when the elevator responds to the landing call signal and stops before arriving at the vulnerable passengers’ destination floor, thereby reducing the risk of vulnerable passengers’ destination floor information being leaked;

[0079] 2) Reducing the number of stops before completing the transportation of vulnerable passengers and shortening the service duration for vulnerable passengers will help reduce the adverse effects on other passengers caused by the elevator's service to vulnerable passengers and help the elevator reduce its operating energy consumption (because the elevator transports suspicious passengers first and then vulnerable passengers, vulnerable passengers cannot get off the elevator in time and move with the car for a long time, which will increase the elevator's energy consumption).

[0080] Of course, step A1 can also cancel the elevator's response to all floor call signals, but compared with this processing method, the processing method of step A1 in this embodiment can avoid negative impact on the elevator experience (mainly the waiting stage) of waiting passengers corresponding to other call signals except the floor call signals that cause the elevator to stop before reaching the destination floor of the vulnerable passengers (that is, the elevator can respond normally to the call signals of these waiting passengers as soon as possible), while achieving the same reduction in the risk of leakage of the destination floor information of vulnerable passengers.

[0081] In addition, if it is possible to determine whether the passenger waiting for the elevator in the elevator lobby is a suspicious passenger, step A1 can be modified as follows:

[0082] Step A1, canceling the response of the elevator to the landing call signal from the suspicious passenger in the elevator lobby, which makes the elevator stop before reaching the vulnerable passenger's destination floor.

[0083] Obviously, the modified step A1 can further reduce the number of waiting passengers corresponding to other elevator call signals except the landing call signal that causes the elevator to stop before reaching the destination floor of the vulnerable passengers.

[0084] Example 3

[0085] This embodiment further defines and explains the embodiment 1 or 2.

[0086] like Figure 3 As shown, the elevator control method for preventing leakage of destination floor information of vulnerable passengers in this embodiment further includes before step 6 and adjacent to step 6 and / or after step 6 and adjacent to step 6:

[0087] Step A2: Control the elevator to stop at least one floor.

[0088] The purpose of adding step A2 is to avoid the risk of the vulnerable passenger's destination floor information being leaked to suspicious passengers who share the same elevator with the vulnerable passenger (hereinafter referred to as suspicious passengers in the same elevator). That is, if the suspicious passenger in the same elevator gets off the elevator before the vulnerable passenger and stays in the elevator lobby at the destination floor, the next elevator stop destination floor can be observed and regarded as the vulnerable passenger's destination floor. In order to avoid this leakage risk, step A2 stops at least one floor before step 6 and adjacent to step 6 and / or after step 6 and adjacent to step 6. In this way, for the observation results of suspicious passengers in the same elevator, the vulnerable passenger has multiple possible destination floors, making it difficult to correctly determine the vulnerable passenger's real destination floor.

[0089] Obviously, the addition of step A2 solves the problem of how to prevent the vulnerable passenger's destination floor information from being leaked to the suspicious passengers who get off the elevator.

[0090] Example 4

[0091] This embodiment further defines and explains the third embodiment.

[0092] In this embodiment, when step A2 is located after step 6 and adjacent to step 6, step A2 controls the elevator to finally stop at the dispersed standby floor of the elevator.

[0093] The purpose of this technical feature is to achieve the risk of avoiding the vulnerable passenger's destination floor information being leaked to suspicious passengers who get off the elevator, while displaying the elevator's decentralized standby state. This makes it unnecessary for the elevator to be put into standby state after waiting for a certain period of time without any passenger call signal after the vulnerable passenger gets off the elevator, and then restart and stop at the pre-determined decentralized standby floor to implement decentralized standby. This is beneficial to reducing the elevator's energy consumption and reducing the wear and tear of elevator-related components.

[0094] Example 5

[0095] This embodiment further defines and explains the embodiments 1 to 4.

[0096] In this embodiment, after step 5 and adjacent to step 5, the following further includes: step A3, canceling the floor station device providing the elevator car position information to the waiting passengers; before step 7 and adjacent to step 7, the following further includes: step A4, restoring the floor station device providing the elevator car position information to the waiting passengers.

[0097] Figure 4 The result after adding step A4 on the basis of Example 3 or Example 4 is shown. The result after adding step A4 on the basis of Example 1 or Example 2 can be Figure 4 Based on the above, the steps missing from Example 1 or Example 2 relative to Example 3 can be deleted, which will not be shown in the figure here, and the following will beFigure 4 Based on this, the descriptions of other situations can be referred to Figure 4 and its description to obtain.

[0098] The purpose of adding step A3 and step A4 is to hide the destination floor information of the vulnerable passengers, so that the passengers in the waiting hall (including suspicious passengers and non-suspicious passengers) cannot guess the destination floor information of the vulnerable passengers. Of course, from the actual effect (that is, the effect of the risk that the destination floor information of the vulnerable passengers is guessed by the passengers in the waiting hall), it is preferably that there is step A2 between step A4 and step 6 to prevent the passengers in the waiting hall from simply guessing that the floor where the elevator is stationary is the destination floor of the vulnerable passengers, because some passengers cannot know whether the elevator has stopped at the destination floors of other co-riding passengers who are not vulnerable passengers before and after stopping at the destination floor of the vulnerable passengers, and whether it has stopped at a non-passenger destination floor for the purpose of confusion.

[0099] Embodiment 6

[0100] This embodiment makes a further limited description on the basis of Embodiment 5.

[0101] In Embodiment 5, step A3 and step A4 are to cancel and restore the floor station device to provide the elevator car position information to the waiting passengers. As a result, during the elevator transporting the vulnerable passengers, all floor stations do not display the elevator car position information. Such a processing method makes it impossible for all waiting passengers at the destination floor (including suspicious passengers and non-suspicious passengers) to obtain the destination floor information of the elevator car, which is obviously unreasonable. For example, for the waiting passengers on the floors other than the departure floor of the vulnerable passengers and the destination floor of the suspicious passengers, they do not know that the passengers in the current elevator are vulnerable passengers. Therefore, even if these passengers obtain the current stopping floor information of the elevator, they will not associate this floor with the vulnerable passengers. Therefore, it is meaningless for the floor station devices on the floors other than the departure floor of the vulnerable passengers and the destination floor of the suspicious passengers not to provide the elevator car position information to the waiting passengers to reduce the risk of leakage of the destination floor information of the vulnerable passengers.

[0102] After analysis, it is determined that in addition to two situations, there may be a risk that the destination floor information of the vulnerable passengers is leaked to the suspicious passengers when the floor station device provides the destination floor information of the vulnerable passengers:

[0103] Case 1: After the suspicious passenger gets off the elevator before the vulnerable passenger, he stays in the waiting hall of the destination floor and can observe the next destination floor of the elevator and regard it as the destination floor of the vulnerable passenger. If step A2 in the embodiment is not taken, the suspicious passenger who stays on the departure floor of the vulnerable passenger and observes the stop of the elevator will be suspicious of the floor where the elevator is located when the floor station device is restored to display the vulnerable passenger's destination floor based on his observation results, because some passengers cannot know whether the elevator has stopped at the destination floor of other non-vulnerable passengers before and / or after stopping at the vulnerable passenger's destination floor, and whether it has stopped at a non-passenger destination floor for the purpose of confusion. Therefore, it is necessary to control the display of the floor station device of the departure floor of the vulnerable passenger to the floor where the elevator is located during the elevator transporting the vulnerable passenger, so as to avoid the vulnerable passenger's destination floor information being leaked to the suspicious passengers who get off the elevator.

[0104] Case 2: At the departure floor of the vulnerable passenger (such as the lobby on the first floor at the entrance and exit of a building), after the vulnerable passenger enters the car, if the suspicious passenger does not enter the car to ride with the vulnerable passenger, but stays at the departure floor of the vulnerable passenger and observes the stop of the elevator, if step A2 in the embodiment is not taken, the suspicious passenger who stays at the departure floor of the vulnerable passenger and observes the stop of the elevator can, based on his observation results, confirm the floor where the elevator is located when the display of the floor station device is restored as the destination floor of the vulnerable passenger, because some passengers cannot know whether the elevator has stopped at the destination floor of other non-vulnerable passengers before and / or after stopping at the destination floor of the vulnerable passenger, and whether it has stopped at the destination floor of non-passengers for the purpose of confusion. This is the same as the situation when riding with a suspicious passenger. Therefore, it is necessary to control the display of the floor information of the elevator during the elevator transporting the vulnerable passenger by the floor station device of the departure floor of the vulnerable passenger, so as to avoid the destination floor information of the vulnerable passenger being leaked to the suspicious passenger at the departure floor of the vulnerable passenger.

[0105] Based on the above analysis, this embodiment proposes the following modifications to step A3 and step A4 in embodiment 5:

[0106] Step A3 only cancels the floor station devices located at the suspicious passenger's destination floor and / or the vulnerable passenger's departure floor from providing the elevator car position information to the waiting passengers; correspondingly, step A4 only restores the floor station devices located at the suspicious passenger's destination floor and / or the vulnerable passenger's departure floor from providing the elevator car position information to the waiting passengers.

[0107] Example 7

[0108] This embodiment is further limited and described on the basis of Embodiment 5 or 6.

[0109] This embodiment further analyzes suspicious passengers located on the departure floor of vulnerable passengers.

[0110] We make a reasonable assumption that there will not be multiple suspicious individuals in the same elevator lobby at the same time. This is because in terms of the efficiency of obtaining the destination floor information of vulnerable passengers from suspicious individuals, the number of destination floors of vulnerable passengers obtained by multiple people watching an elevator at the same time is the same as that of a single person watching an elevator.

[0111] In the case where there is only one suspicious person watching the departure floor of the vulnerable passenger (such as the first floor lobby at the entrance and exit of the building), if the vulnerable passenger takes the same elevator and leaves the first floor lobby, he is likely to miss other vulnerable passengers who follow him, so he is likely to stay in the first floor lobby and observe whether there are vulnerable passengers taking the elevator and going to their destination floor. In this case, it is only necessary to prevent the landing device located at the departure floor of the vulnerable passenger from providing the elevator's floor stop information during the period when the elevator (only) transports the vulnerable passenger.

[0112] The above analysis provides the implementation conditions for step A3 and step A4, that is, only when there is no suspicious passenger entering the elevator car at the departure floor of the vulnerable passenger and riding the elevator with the vulnerable passenger, step A3 will cancel the floor station device located at the departure floor of the vulnerable passenger to provide the elevator car location information to the waiting passengers.

[0113] Example 8

[0114] like Figure 5 As shown, the elevator control method for preventing the leakage of destination floor information of vulnerable passengers in this embodiment is characterized in that the control method includes:

[0115] Step S1: determine whether a vulnerable passenger is detected entering the elevator car. If so, proceed to the next step. Otherwise, control the elevator to respond to the passenger's elevator demand in a normal mode, and end;

[0116] Step S2, determining whether there is a first suspicious passenger in the elevator car before the vulnerable passenger enters the elevator car, if so, refusing to receive the destination floor registration information of the vulnerable passenger and proceeding to the next step, otherwise directly proceeding to the next step;

[0117] Step S3, determining whether there is a second suspicious passenger following the vulnerable passenger into the elevator car after the vulnerable passenger enters the elevator car, if so, receiving the destination floor information of the second suspicious passenger and proceeding to the next step, otherwise directly proceeding to the next step;

[0118] Step S4, controlling the elevator to stop at each destination floor of the suspicious passengers until there are no more suspicious passengers in the car;

[0119] Step S5, recovering and receiving the destination layer information of the vulnerable passengers;

[0120] Step S6, controlling the elevator to stop at the destination floor of the vulnerable passenger;

[0121] Step S7, end.

[0122] Different from Example 1, this embodiment handles the first suspicious passenger and the second suspicious passenger as follows: when the first suspicious passenger and / or the second suspicious passenger are in the car, the elevator refuses to accept the registration of destination floor information of the vulnerable passenger, and only accepts the registration of destination floor information of the vulnerable passenger after the elevator completes the transportation of all non-suspicious passengers, and transports the vulnerable passenger. Since there are no suspicious passengers in the car when the vulnerable passenger registers his or her destination floor information, the possibility of the vulnerable passenger's destination floor being leaked to the first suspicious passenger and the second suspicious passenger can be eliminated, so this solution can reduce the risk of leakage of the vulnerable passenger's destination floor information.

[0123] Example 9

[0124] This embodiment further defines and explains the embodiment 1.

[0125] like Figure 6 As shown, between step S5 and step S6, it also includes:

[0126] Step SB1, canceling the elevator's response to the landing call signal that causes it to stop before reaching the vulnerable passenger's destination floor.

[0127] The purpose of adding step SB1 is to reduce the number of stops before the elevator completes the transportation of vulnerable passengers, shorten the service duration for vulnerable passengers, help reduce the adverse effects of the elevator on other passengers due to serving vulnerable passengers, and help the elevator reduce its operating energy consumption.

[0128] Before the step S6 and adjacent to the step S6 and / or after the step S6 and adjacent to the step S6, the following further includes: step SB2, controlling the elevator to randomly stop at at least one floor.

[0129] The purpose of adding step SB2 is to avoid the risk of the vulnerable passenger's destination floor information being leaked to suspicious passengers who share the same elevator with the vulnerable passenger, that is, if the suspicious passenger gets off the elevator before the vulnerable passenger and stays in the elevator lobby at the destination floor, the next elevator stop destination floor can be observed and regarded as the vulnerable passenger's destination floor. In order to avoid this leakage risk, step SB2 stops at at least one floor before and adjacent to step S6 and / or after and adjacent to step S6. In this way, for the observation results of the suspicious passengers, the vulnerable passenger has multiple possible destination floors, making it difficult to correctly determine the vulnerable passenger's real destination floor.

[0130] When step SB2 is located after step S6 and adjacent to step S6, step SB2 controls the elevator to finally stop at the decentralized standby floor of the elevator. The purpose of this technical feature is to avoid the risk of the vulnerable passenger's destination floor information being leaked to the suspicious passengers who get off the elevator, and at the same time display the decentralized standby of the elevator, so that the elevator does not need to be started again and parked at the pre-determined decentralized standby floor for decentralized standby after the vulnerable passenger gets off the elevator due to waiting for a certain period of time without the passenger calling signal, so it is beneficial to reduce the power consumption of the elevator and reduce the wear and tear of the relevant parts of the elevator.

[0131] like Figure 7 As shown, between step S4 and step S6, the following is also included: step SB3, canceling the floor station device to provide the elevator car position information to the waiting passengers; before step S7 and adjacent to step S7, the following is also included: step SB4, restoring the floor station device to provide the elevator car position information to the waiting passengers. The purpose of adding step SB3 and step SB4 is to hide the destination floor information of vulnerable passengers, so that passengers in the elevator lobby (including suspicious passengers and non-suspicious passengers) cannot guess the destination floor information of vulnerable passengers.

[0132] In order to reduce meaningless cancellation of the floor station devices providing elevator car position information to waiting passengers, step SB3 only cancels the floor station devices located at the suspicious passenger destination floor and / or the vulnerable passenger departure floor to provide elevator car position information to waiting passengers.

[0133] Preferably, step SB3 cancels the floor device located at the vulnerable passenger's departure floor from providing the elevator car location information to the waiting passengers only when no suspicious passenger enters the elevator car at the vulnerable passenger's departure floor and rides the elevator with the vulnerable passenger.

[0134] Example 10

[0135] This embodiment involves a situation where the departure floor information of a vulnerable passenger may be leaked to suspicious elements (i.e., suspicious passengers). That is, when the vulnerable passenger is located at a non-terminal floor, if there is already a suspicious passenger in the elevator car, when the elevator car responds to the vulnerable passenger's elevator call signal and stops at the vulnerable passenger's waiting floor, even if the vulnerable passenger does not enter the car, the vulnerable passenger's boarding floor (i.e., departure floor) will be obtained by suspicious elements in the car. The leakage of the vulnerable passenger's departure floor information to suspicious elements is also dangerous and should be avoided.

[0136] To solve this problem, Figure 8 As shown, this embodiment proposes the following elevator control method for preventing the leakage of departure floor information of vulnerable passengers, including:

[0137] Step T1, receiving a passenger elevator call signal;

[0138] Step T2: determine whether the elevator call signal comes from a vulnerable passenger. If so, proceed to the next step. Otherwise, control the elevator to respond to the passenger's elevator call signal in a normal mode, and end;

[0139] Step T3: determine whether there is a suspicious passenger in the elevator before the elevator arrives at the departure floor of the vulnerable passenger. If so, proceed to the next step; otherwise, control the elevator to respond to the passenger's elevator call signal in a normal mode, and end;

[0140] Step T4: Ignore the elevator call signal of the vulnerable passenger and transport the suspicious passenger, and return to step T3.

[0141] Here, the method of determining whether the elevator call signal comes from a vulnerable passenger in step T2 includes but is not limited to:

[0142] Method 1: Use the passenger's identity information to determine whether the elevator call signal comes from a vulnerable passenger based on the correspondence between the pre-registered identity information and whether the passenger is a vulnerable passenger. There is no restriction on how to determine the passenger's identity information, such as: when the vulnerable passenger registers his / her elevator call signal by mobile phone or other means, the passenger's mobile phone ID is used; when the passenger swipes a card, the passenger's identity is determined by the card information; when a biometric identification device is installed at the landing station, the passenger's identity is determined by the biometric identification device; when a camera device for acquiring passenger images is installed at the landing station, the passenger's identity can be determined based on the image recognition result, etc.;

[0143] Method 2: In addition to receiving ordinary elevator call signals from vulnerable passengers, the elevator call signal registration device at the floor station also receives special requests from vulnerable passengers to protect their privacy information (such as the departure floor). In this case, the elevator call signal received in step T1 should include the special request information.

[0144] This embodiment also does not limit the judgment of whether the passenger in the elevator car is a suspicious person (i.e., a suspicious passenger) when the elevator stops at the waiting floor of vulnerable passengers (i.e., its departure floor). For example, a camera in the elevator car (currently, the installation rate of cameras in elevator cars is very high) can be used to determine whether the existing passengers in the elevator car are suspicious persons by using image recognition.

[0145] It is not difficult to understand that when step T4 determines in step T3 that there is a suspicious passenger in the car when the elevator arrives and stops at the departure floor of the vulnerable passenger, the vulnerable passenger's call signal is ignored and the suspicious passenger is transported. Such processing measures are obviously sufficient to eliminate the possibility that the departure floor information of the vulnerable passenger is obtained by suspicious elements in the car when the elevator stops at the departure floor of the vulnerable passenger in response to the call signal of the vulnerable passenger, thereby avoiding the risk of the departure floor information of the vulnerable passenger being leaked to suspicious elements.

[0146] Embodiment 11

[0147] This embodiment further defines and explains the embodiment 10.

[0148] In this embodiment, between step T2 and step T3, the elevator control method for preventing leakage of destination floor information of vulnerable passengers further includes:

[0149] Step C1: determine whether the current running direction of the elevator is consistent with the expected riding direction of the vulnerable passenger. If so, proceed to the next step; otherwise, wait until the elevator runs in the reverse direction.

[0150] Because when the elevator car is running in a certain direction, it will only respond to the elevator call signal whose expected riding direction (i.e., a certain direction that the passenger expects the elevator car to go after entering the car) is consistent with the current running direction of the elevator (i.e., the destination floor of the car is located ahead of its departure floor relative to the current running direction) (unless the elevator does not need to stop at the departure floor of the elevator call signal ahead of the running direction and reverses the running direction), so the addition of step C1 can significantly simplify the judgment of the subsequent step T3.

[0151] Example 12

[0152] This embodiment further defines and explains the embodiment 11.

[0153] Step T3 determines whether there is a suspicious passenger in the car according to the following rules:

[0154] When there is a suspicious passenger in the car who will not get off before the elevator stops at the departure floor of the vulnerable passenger in response to the call signal of the vulnerable passenger, the step T3 determines that there is a suspicious passenger in the car.

[0155] Further, when the destination floor of the suspicious passenger is located ahead of the departure floor of the vulnerable passenger relative to the elevator running direction, the step T3 determines that the suspicious passenger will not get off the elevator before the departure floor of the vulnerable passenger.

[0156] Example 13

[0157] This embodiment further defines and explains the embodiment 11.

[0158] Another rule for determining whether there is a suspicious passenger in the car in step T3 is:

[0159] When at least one of the following conditions is met, step T3 determines that there is no suspicious passenger in the car when the elevator arrives and stops at the vulnerable passenger departure floor:

[0160] Condition 1: The destination floors of all suspicious passengers in the car are between the current floor of the elevator car and the departure floor of the vulnerable passengers, and there is no elevator call signal from suspicious passengers whose departure floor is between the current floor of the elevator car and the departure floor of the vulnerable passengers;

[0161] Condition 2: There is no suspicious passenger in the current car and there is no elevator call signal from a suspicious passenger whose departure floor is between the current floor of the elevator and the departure floor of the vulnerable passenger.
