Reminder method for passengers in elevator car

Abstract

The present invention discloses a reminder method for passengers in an elevator car. The method identifies a first passenger entering an elevator car running in a first direction on a first floor. When a reminder condition is met, a reminder message is provided to the first passenger. The reminder message is used to remind the first passenger to perform a destination floor registration operation, or to indicate that a destination floor has been registered. The reminder conditions include: Condition 1: The first passenger does not perform a destination floor registration operation within a given time period after entering the elevator car. The given time period is a time period starting at a specific time and having a pre-specified length parameter. The present invention correctly identifies passengers who enter the elevator car under preset circumstances but do not perform a destination floor registration operation, and provides these passengers with a destination floor registration operation reminder, thereby preventing passengers from being unable to successfully reach their destination floor due to not registering their destination floor.

Description

Technical Field

[0001] The present invention relates to the field of elevators, and in particular to a reminding method for passengers in an elevator car. Background Art

[0002] At present, there are technical solutions for reminding passengers to get off the elevator in the existing technology. For example: Document 1 (CN202111134442.1) proposes to assign an unused reminder lighting mode to the passenger's destination floor, and when the elevator car is about to arrive at or has already docked at a certain destination floor, the lighting device in the elevator car is controlled to illuminate with the reminder lighting mode corresponding to the destination floor, thereby realizing the reminder of the passengers who are about to get off the elevator at the destination floor; Document 2 (CN202110980795.7) estimates the elevator car's required car movement time from the current moment until it reaches the destination floor of the visually impaired passenger, determines the reminder time according to the elevator departure time and car movement time required for the visually impaired passenger to leave the elevator car, and reminds the visually impaired passenger to get off the elevator at the reminder time. These existing technologies all implement reminders for passengers to get off the elevator. In fact, after entering the elevator car from the landing station, the passenger may not perform the destination floor registration operation for various reasons, such as thinking about something, playing with the mobile phone, etc., or may mistakenly believe that his destination floor has been registered. For example, a passenger enters the descending elevator car at the middle floor and wants to go to the lobby on the first floor. There are already many descending passengers in the car, making the car relatively crowded, but the destination floor of these existing passengers is the second floor, not the first floor. The passengers who enter the car later think that the existing passengers must be (at least some of them) going to the first floor. Therefore, the passengers who enter later will not check whether the first floor has been registered and take it for granted that the first floor has been registered.

[0003] Regardless of the scenario, if a passenger enters the elevator car without registering the destination floor, it may not be able to reach the destination floor smoothly. Therefore, it is necessary to give appropriate reminders to passengers in the elevator car who enter the elevator car but do not perform the destination floor registration operation.

[0004] Therefore, determining under what circumstances it is necessary to remind passengers who have entered the elevator car but have not performed the destination floor registration operation has become a technical problem to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to determine under what circumstances it is necessary to remind passengers who have entered the elevator car but have not performed the destination floor registration operation.

[0006] In order to solve the above technical problems, the present invention discloses a reminder method for passengers in an elevator car, which identifies a first passenger entering an elevator car running in a first direction at a first floor. When a reminder condition is met, a reminder message is provided to the first passenger; the reminder message is used to remind the first passenger to perform a destination floor registration operation, or to indicate that the destination floor is currently registered; the reminder condition includes:

[0007] Condition 1: The first passenger fails to register for the destination floor within a given time period after entering the elevator car;

[0008] The given time period is a time period starting at a specific moment and having a length equal to a pre-specified length parameter; the method for determining the specific moment is: starting from the first entry moment of the first passenger entering the elevator car, if the elevator running direction does not reverse before the timing result exceeds a pre-specified time threshold, the first entry moment is used as the specific moment; otherwise, the reversal moment of the elevator running direction is used as the specific moment.

[0009] Preferably, when the first entry time is used as the specific time, the reminder condition further includes: Condition 2: the first passenger does not perform a check operation on the registered destination floor on the destination floor registration device in the car.

[0010] Preferably, the reminder conditions also include: Condition 3, before the first passenger enters, there is no second passenger in the elevator car before the first passenger enters the elevator car; Condition 4, after the first passenger enters the car, the elevator remains stationary at the first passenger's waiting floor for a duration exceeding a time threshold.

[0011] Preferably, the reminder conditions also include: Condition 5, before the first passenger enters, there is no second passenger in the elevator car before the first passenger enters the elevator car; Condition 6, there is an elevator call signal that the elevator has not responded to in front of the first floor relative to the first direction.

[0012] Preferably, the reminder conditions also include: Condition 7, before the first passenger enters, there is at least one second passenger in the elevator car who enters the elevator car earlier than the first passenger; Condition 8, the destination floor of at least one second passenger is located in front of the first floor relative to the first direction.

[0013] Preferably, the reminder condition further includes: Condition 9, there is an elevator call signal that has not been responded to by the elevator in front of the first floor relative to the first direction.

[0014] Preferably, when the first entry moment is used as the specific moment, the reminder condition also includes: Condition 10, the first passenger performs an inspection operation on the registered destination floor on the destination floor registration device in the car; Condition 11, there are influencing factors that affect the correctness of the inspection results of the first passenger.

[0015] Preferably, the influencing factor is that there is an obstruction between the first passenger and the elevator car destination floor registration device that affects the first passenger's ability to check the registered destination floor on the destination floor registration device in the car.

[0016] Preferably, the reminder method uses any of the following methods to implement the judgment of whether condition 11 is met: Method 1, there is at least one second passenger other than the first passenger, and the distance between the second passenger and the destination floor registration device in the car is less than a threshold; Method 2, there is at least one second passenger other than the first passenger, and the second passenger is located between the first passenger and the destination floor registration device in the car; Method 3, the shortest distance between the first passenger's destination floor identifier and the registered destination floor identifier is less than a threshold or the first passenger's destination floor identifier has at least one registered destination floor identifier adjacent to it.

[0017] Preferably, when the first entry moment is used as the specific moment, the reminder condition also includes: Condition 12, before the first passenger enters, there is at least one second passenger in the elevator car who enters the elevator car earlier than the first passenger; Condition 13, the second registration moment when the second passenger registers his / her second destination floor after entering the elevator car is earlier than the first entry moment when the first passenger enters the elevator car; Condition 14, the first passenger's expected elevator direction is consistent with the elevator operation direction; Condition 15, the second destination floor does not include the high-probability floor ahead of the first passenger's departure floor relative to the first direction, or the high-probability floor ahead of the first passenger's departure floor relative to the first direction has not yet been registered, and the high-probability floor refers to the floor whose probability of becoming the passenger's destination floor is higher than a threshold.

[0018] Preferably, the reminder condition further includes: Condition 16, the second destination floor is located in front of the high-probability floor relative to the second direction.

[0019] Preferably, the reminder condition also includes: Condition 17, the high-probability floor is located in front of the second destination floor relative to the second direction, and there is an elevator call signal that has not been responded to by the first elevator, and the departure floor of the elevator call signal is located in front of the high-probability floor relative to the second direction, or is located in the opposite direction of the second destination floor relative to the second direction.

[0020] Preferably, the reminder condition further includes: condition 18, the second destination floor is adjacent to the high probability floor, or the minimum distance between the second destination floor and the high probability floor is less than a threshold or is adjacent.

[0021] Preferably, the reminder conditions also include: Condition 19, the first passenger performs an inspection operation on the registered destination floor on the destination floor registration device in the car; Condition 20, the distance between the position of the second passenger and the destination floor registration device in the elevator car is less than a first threshold, and / or the second passenger is located between the first passenger and the destination floor registration device in the elevator car, resulting in a line of sight obstruction for the first passenger relative to the destination floor registration device in the elevator car.

[0022] Preferably, the reminder condition also includes: condition 21, the second number of passengers is greater than a second threshold, or the ratio of the second number of passengers to the rated passenger capacity of the elevator car is greater than a third threshold, or the congestion of the elevator car exceeds a threshold.

[0023] Preferably, the first passenger is a passenger who rides the elevator in reverse, and the given time period is a time period starting from the moment when the passenger actually expects the direction of riding to be consistent and having a length parameter specified in advance.

[0024] Beneficial technical effects:

[0025] The present invention correctly identifies passengers who enter the elevator car under preset circumstances but do not perform the destination floor registration operation, and reminds these passengers to perform the destination floor registration operation, thereby preventing passengers from being unable to reach their destination floor smoothly due to not registering their destination floor. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] No attached pictures DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] The key to the technical problem of reminding passengers to register their destination floors is: how to determine whether the reminder needs to be provided to the passengers. Therefore, this application focuses on exploring: when what conditions are met, it can be determined that the passenger needs to be provided with a reminder to remind the passenger to register his destination floor.

[0029] Example 1

[0030] This embodiment provides a reminder method for passengers in an elevator car, which identifies a first passenger entering an elevator car running in a first direction at a first floor. When a reminder condition is met, a reminder message is provided to the first passenger; the reminder message is used to remind the first passenger to perform a destination floor registration operation, or to indicate that the destination floor is currently registered. The reminder condition includes:

[0031] Condition 1: The first passenger fails to register for the destination floor within a given time period after entering the elevator car;

[0032] The given time period is a time period starting at a specific moment and having a length equal to a pre-specified length parameter; the method for determining the specific moment is: starting from the first entry moment of the first passenger entering the elevator car, if the elevator running direction does not reverse before the timing result exceeds a pre-specified time threshold, the first entry moment is used as the specific moment; otherwise, the reversal moment of the elevator running direction is used as the specific moment.

[0033] In addition, the length parameter can be a constant value or a variable value. For example, the length parameter can be determined based on the distance between the elevator car and the front of the current running direction (that is, when the elevator car reaches this point, it will reverse the running direction or stop running and wait for a new elevator call instruction). Generally, the longer the distance, the larger the length parameter; preferably, a reasonable maximum value is set for the length parameter.

[0034] In engineering practice, it is impossible to remind passengers to register their destination floor as soon as they enter the elevator car, as doing so would cause inconvenience to the passengers and affect their elevator riding experience. Therefore, we set the aforementioned reminder conditions for passengers to perform the destination floor registration operation. This condition actually includes two key points, namely a given time period and the failure to perform the registration operation. Only when these two key points are met at the same time will the passenger be reminded. Of course, these two key points are still very loose conditions, and it is still possible that unnecessary reminders are given to passengers. Considering that even if unnecessary reminders are given to passengers, there will not be overly serious adverse effects, the solution of this embodiment is still a technical solution with practical feasibility.

[0035] It should be emphasized that the definition of a given time period here actually includes two situations: one is when a passenger wants to go down and enters the down elevator car but has not yet registered their destination floor. In this case, the timer can start from the moment the passenger enters the car. When the given timer expires, it is determined that the passenger needs to be reminded. The other is for a more special scenario - passengers taking the elevator in reverse. For passengers taking the elevator in reverse, they may or may not register their destination floor immediately after entering the car. They usually wait until the elevator reverses its direction before registering. However, even if they register immediately, the elevator usually clears all previously registered destination floors when it changes its direction. Therefore, even passengers who have already registered their destination floor in reverse still need to perform the destination floor registration operation again. Considering the elevator's clearing behavior, it is necessary to ensure that passengers taking the elevator in reverse register after the elevator changes its direction. Therefore, we choose the moment when the elevator reverses its direction or the moment when the actual desired direction of the elevator in reverse becomes consistent with the elevator's direction (in fact, this moment is the moment when the elevator reverses its direction) as the start time of the timer. In addition, considering that it is difficult to immediately determine whether the first passenger enters the elevator car or not (usually this can only be determined after the elevator reverses its direction), if we simply use the first entry moment of the first passenger and the moment when the elevator's direction is consistent with the passenger's actual desired direction (or the moment when the elevator reverses its direction) as the starting time for timing, we will inevitably have to wait until the elevator reverses its direction before timing begins, which is obviously unreasonable. For example, if a building has a total of 20 floors, a passenger registers a down call signal from the 10th floor and enters the down elevator on the 10th floor, then leaves the car on the 1st floor. The elevator reverses its direction only after arriving at the 1st floor. It is obviously unreasonable to start timing at this time. For this reason, a time threshold is further introduced to limit the timing start time, so that the aforementioned unreasonable phenomenon can be avoided.

[0036] Therefore, the selection of the timing start time is based on a full analysis of the situation in which the passenger registration operation is required, while considering how to avoid causing unnecessary trouble to the passengers. The timing method is first proposed, and then the timing start time is appropriately selected.

[0037] Example 2

[0038] The reminder conditions in Example 1 are still very loose, and unnecessary reminders may be generated in many cases. Therefore, this embodiment further adds new reminder conditions based on Example 1 to reduce the probability of unnecessary reminders.

[0039] When the given time period is a time period starting from the first entry moment of the first passenger entering the elevator car and having a length equal to a pre-specified length parameter, that is, when the first entry moment is used as the specific moment, the reminder condition further includes:

[0040] Condition 2: The first passenger does not perform a check operation on the registered destination floor on the destination floor registration device in the car.

[0041] Example 1: Passenger A wants to take the elevator from the 10th floor, where he is currently located, to the 1st floor lobby. After arriving at the 10th floor elevator lobby, he registers a down call by pressing the up and down buttons on the landing. The elevator responds to the call and descends from the 20th floor to the 10th floor, where it stops and opens its doors. Passenger A enters the elevator car, and the doors close. Passenger A is engrossed in a mobile game and forgets to register his destination floor, the 1st floor. Within a given period of time (e.g., 20 seconds) after entering the elevator car, Passenger A does not look up to check the elevator's currently registered floor. In this case, we believe it is necessary to remind Passenger A to register to avoid delaying his arrival at his destination floor, the 1st floor.

[0042] Compared to Example 1, this embodiment adds Condition 2, which ensures that the elevator only reminds passengers if they do not check the registered destination floor on the in-car destination floor registration device. This prevents the elevator from reminding passengers to register even if they have confirmed that the first floor button has been registered. Therefore, compared to Example 1, the reminder in this embodiment is more accurate.

[0043] Example 3

[0044] This embodiment further adds new reminder conditions based on embodiment 1 or embodiment 2.

[0045] The reminder conditions also include:

[0046] Condition 3: Before the first passenger enters, there is no second passenger in the elevator car who entered the elevator car earlier than the first passenger;

[0047] Condition 4: After the first passenger enters the car, the elevator remains stationary at the first passenger waiting floor for a period exceeding a threshold.

[0048] In this case, after the first passenger enters the elevator car and does not register the destination floor, the elevator will stay at the first passenger's departure floor for a long time until the first passenger registers the destination floor or a new waiting signal appears. In this case, it is actually necessary to remind the first passenger to register. Although the first passenger's failure to register will neither affect the riding experience of other passengers nor reduce the operating efficiency of the elevator, it will at least waste the first passenger's time. Therefore, it is still necessary to remind the first passenger to register.

[0049] Example 4

[0050] This embodiment further adds new reminder conditions based on embodiment 1 or embodiment 2.

[0051] The reminder conditions also include:

[0052] Condition 5: Before the first passenger enters, there is no second passenger in the elevator car who entered the elevator car earlier than the first passenger;

[0053] Condition 6: There is an elevator call signal that has not yet been responded to by the elevator ahead of the first floor relative to the first direction.

[0054] The addition of conditions 5 and 6 indicates that the elevator currently has no destination floor for passengers in the car that has not yet stopped, and there is an elevator call signal that has not yet been responded to by the elevator in front of the first floor relative to the first direction.

[0055] Like this, when the first passenger does not register the destination floor within the given time period after entering the elevator car, the elevator will continue to move forward, and like this, the elevator car may pass the first passenger's destination floor, thereby making it impossible for the first passenger to arrive at his destination floor smoothly.

[0056] Example 2, based on Example 1, adds: When passenger A enters the elevator car, there are no other passengers in the car, and passenger B is at floor B1 and has registered an up call. Obviously, if passenger A is not reminded to register, the elevator will directly pass the 1st floor in response to passenger B's call and stop at floor B1, reversing its direction. Passenger A will then be unable to leave the elevator car on the 1st floor in time as the elevator descends. He can only leave the elevator car on the 1st floor after registering for the 1st floor before the elevator ascends from B1 and reaches the 1st floor. Obviously, passenger A not only increases his elevator ride time, but may also reduce elevator efficiency (for example, if passenger B's destination floor is not the 1st floor). Therefore, it is necessary to remind passenger A to register his destination floor at the latest before the elevator descends to the deceleration point on the 1st floor (of course, considering that passenger A's operation and the information processing of the elevator control system require a certain amount of time, it is actually necessary to have a time margin in advance of the time when the elevator car reaches the deceleration point).

[0057] Example 5

[0058] This embodiment further adds new reminder conditions based on embodiment 1 or embodiment 2.

[0059] Reminder conditions also include:

[0060] Condition 7: Before the first passenger enters, there is at least one second passenger in the elevator car who enters the car earlier than the first passenger;

[0061] Condition 8: The destination floor of at least one second passenger is located ahead of the first floor relative to the first direction.

[0062] Optionally, the reminder conditions may also include:

[0063] Condition 9: There is an elevator call signal that has not yet been responded to by the elevator ahead of the first floor relative to the first direction.

[0064] Here, we generally assume that passengers follow the principle of "first down, last up" when riding an elevator. That is, passengers waiting at a landing always wait until all passengers intending to disembark have left the elevator before entering. Therefore, conditions 7 and 8 indicate that there is at least one second passenger in the elevator car who has the same desired boarding direction as the first passenger and whose destination floor is ahead of the first passenger's departure floor relative to the direction of elevator travel. Therefore, if the first passenger enters the elevator car but fails to register a destination floor within a specified timeframe, the elevator will continue traveling. This could result in the elevator car passing the first passenger's destination floor, preventing the first passenger from reaching their destination.

[0065] Example 3, based on Example 1, adds: When passenger A enters the elevator car, passenger B is already in the elevator car and has registered their destination floor - B1. Obviously, if passenger A is not reminded to register, the elevator will directly pass the 1st floor and stop at B1 in response to passenger B's elevator call signal. Passenger A will not be able to leave the car in time on the 1st floor when the elevator descends. Therefore, it is necessary to remind passenger A to register their destination floor at the latest before the elevator reaches the deceleration point on the 1st floor (of course, considering that passenger A's operation and the information processing of the elevator control system all require a certain amount of time, it is actually necessary to add a time margin before the elevator car reaches the deceleration point).

[0066] Example 4, based on Example 1, adds: When Passenger A enters the elevator car, Passenger B is already inside and has registered their destination floor—the 3rd floor. Obviously, if Passenger A is not reminded to register, the elevator will stop at the 3rd floor in response to Passenger B's call. If Passenger A has not yet registered for the 1st floor and Passenger C has registered for the up signal on the 5th floor, the elevator will reverse direction at the 3rd floor and ascend to the 5th floor to provide transportation service for Passenger C. In this way, Passenger A cannot reach the 1st floor smoothly. Even if the 1st floor signal is registered at this time, the elevator will not provide service to Passenger A until it has completed its response to Passenger C. Therefore, it is necessary to remind Passenger A to register their destination floor at the latest before the elevator car reaches the deceleration point corresponding to the destination floor of the passengers in the car and the destination floor of the first passenger, whichever arrives first (also requiring a time margin in advance). Here, the first passenger's destination floor is considered to be the most likely floor ahead in the current direction of the elevator's travel. The method for determining this is described in Example 7.

[0067] Example 6

[0068] This embodiment further adds new reminder conditions based on embodiment 1.

[0069] When the first entry time is used as the specific time, the reminder condition also includes:

[0070] Condition 10: The first passenger performs a check operation for checking the registered destination floor on the destination floor registration device in the car;

[0071] Condition 11: There are factors that affect the correctness of the first passenger's inspection results.

[0072] The influencing factor is that there is an obstruction between the first passenger and the elevator car destination floor registration device that affects the first passenger's ability to check the registered destination floor on the destination floor registration device in the car.

[0073] The reminder method uses any of the following methods to determine whether condition 11 is met:

[0074] Method 1: There is at least one second passenger other than the first passenger, and the distance between the second passenger and the destination floor registration device in the car is less than a threshold;

[0075] Mode 2: There is at least one second passenger other than the first passenger, and the second passenger is located between the first passenger and the destination floor registration device in the car;

[0076] Mode 3: The shortest distance between the first passenger's destination floor identifier and the registered destination floor identifiers is smaller than a threshold, or the first passenger's destination floor identifier has at least one registered destination floor identifier adjacent to it.

[0077] The first passenger's destination floor identification can be identified based on the current time, floor attributes, passenger identity attributes, etc. For example, if it is currently lunch time, for passengers entering the car from a floor other than the cafeteria floor, their destination floor can be considered to be the cafeteria floor; for passengers who have registered for downbound travel at a floor station in a residential building, their destination floor can be considered to be the first floor; for children or passengers carrying children (who can be identified by the camera through image recognition), their destination floor can be considered to be the floor where the children's playground is located in the building.

[0078] This embodiment is directed to a situation where the first passenger checks the registered destination floor after entering the car, but for some reason may find that his destination floor has been registered but is not actually registered.

[0079] Example 5: Passenger A wants to take the elevator from their current location on the 10th floor to the 1st floor lobby. Upon reaching the 10th floor lobby, they register a down call by pressing the up / down buttons on the landing. The elevator responds to the call and descends from the 20th floor to the 10th floor, stopping and opening its doors. Passenger A enters the elevator car, where the doors close. After entering the car, Passenger A may observe the registered and illuminated destination button on the control panel from a distance, believing their destination floor (the 1st floor) is illuminated, and therefore does not register. However, the 1st floor button is not illuminated due to a number of factors that may have misleadingly affected Passenger A's view. These factors may include: 1) Passenger B's position near the control panel obstructs Passenger A's view; 2) Passenger B's position directly on the line connecting the control panel and Passenger A, obstructing Passenger A's view; 3) a button adjacent to the 1st floor button (e.g., the 2nd floor button) is already illuminated, and due to their proximity, Passenger A mistakenly identifies the 2nd floor button as the 1st floor button; and so on. In short, despite checking the "Registered" button, Passenger A did not receive the correct result. The method for obtaining the first passenger's destination floor in Method 3 is described in Example 7. Obviously, in this case, Passenger A should be reminded to register to avoid being unable to successfully reach his destination floor, the 1st floor.

[0080] Example 7

[0081] This embodiment further adds new reminder conditions based on embodiment 1.

[0082] When the first entry time is used as the specific time, the reminder condition also includes:

[0083] Condition 12: Before the first passenger enters the elevator car, there is at least one second passenger who enters the elevator car earlier than the first passenger;

[0084] Condition 13: The second registration time of the second passenger entering the elevator car to register the second destination floor is earlier than the first entry time of the first passenger entering the elevator car;

[0085] Condition 14: The first passenger's desired direction of travel is consistent with the elevator's direction of travel;

[0086] Condition 15: The second destination floor does not include a high-probability floor ahead of the first passenger's departure floor in the first direction, or the high-probability floor ahead of the first passenger's departure floor in the first direction has not yet been registered, where the high-probability floor refers to a floor whose probability of becoming the passenger's destination floor is higher than a threshold.

[0087] Among them, the high-probability floor is determined based on the building attributes, current time period, floor attributes, passenger attributes, etc. For example, during the off-get off work period, the first floor is used as the floor for leaving the office building. If a child passenger goes up from the first floor, he or she is likely to go to the floor where the children's books are located.

[0088] In this embodiment, if the first passenger does not perform the destination floor registration operation after entering, the first passenger's departure floor is first determined relative to a high-probability floor in the first direction based on the building attributes, current time period, floor attributes, passenger attributes, etc., and then the high-probability floor is considered to be the first passenger's destination floor. It is then determined whether the high-probability floor has been registered or included in the second destination floor of the second passenger. If the judgment result is no, it means that the first passenger's destination floor has not been registered, so it is necessary to remind the first passenger to perform the destination floor registration operation.

[0089] The newly added conditions of this embodiment, especially condition 15, further limit the situation that when a passenger enters the car without registering the destination floor, if the passenger's destination floor can be estimated and the estimated result has not been registered, a registration operation reminder will be implemented. This is obviously very scenario-specific and the reminder is very accurate.

[0090] Example 8

[0091] This embodiment further adds new reminder conditions based on embodiment 7. The reminder conditions also include:

[0092] Condition 16: The second destination floor is located in front of the high-probability floor relative to the second direction.

[0093] Similar to Example 4, after adding this condition, if the first passenger does not perform the destination floor level operation in time after entering the car, the elevator will skip its departure floor and arrive at the second destination floor of the second passenger. In this way, the first passenger cannot leave the elevator from its destination floor in time. Therefore, it is necessary to perform the destination floor registration operation reminder for the first passenger.

[0094] Example 9

[0095] This embodiment further adds new reminder conditions based on embodiment 7. The reminder conditions also include:

[0096] Condition 17: The high-probability floor is located in front of the second destination floor relative to the second direction, and there is an elevator call signal that has not been responded to by the first elevator, and the departure floor of the elevator call signal is located in front of the high-probability floor relative to the second direction, or is located in the opposite direction of the second destination floor relative to the second direction.

[0097] Condition 17 actually limits the second passenger's second destination floor to be between the first passenger's first destination floor (i.e., the high-probability floor) and the current position of the elevator car. If the first passenger does not register his destination floor, then without considering other floor station signals, the elevator will not reach the first passenger's destination floor at all but will stop at the second passenger's second destination floor. At this time, if there is an elevator with a specific elevator call signal that has not yet responded, no matter whether the departure floor of the elevator signal is in front of or behind the first passenger's first destination floor, if the first passenger does not register his destination floor, the elevator will respond to the specific elevator call signal after completing the service for the second passenger. Obviously, in this case, the first passenger cannot get the elevator service, so it is necessary to implement a destination floor registration operation reminder for the first passenger.

[0098] Example 10

[0099] This embodiment further adds new reminder conditions based on embodiment 7. The reminder conditions also include:

[0100] Condition 18: The second destination floor is adjacent to the high-probability floor, or the minimum distance between the second destination floor and the high-probability floor is less than a threshold or they are adjacent.

[0101] Condition 18 is essentially used to limit the situation where the first passenger mistakenly regards the registered second destination floor as a high-probability floor when checking the registered button because the second destination floor is too close to or adjacent to the high-probability floor and no longer performs the destination floor registration operation. Therefore, it is necessary to remind the first passenger to perform the destination floor registration operation.

[0102] Example 11

[0103] This embodiment further adds new reminder conditions based on embodiment 7. The reminder conditions also include:

[0104] Condition 19: The first passenger performs a check operation for checking the registered destination floor on the destination floor registration device in the car;

[0105] Condition 20: The distance between the location of the second passenger and the destination floor registration device in the elevator car is less than a first threshold, and / or the second passenger is located between the first passenger and the destination floor registration device in the elevator car, resulting in a visual obstruction of the first passenger relative to the destination floor registration device in the elevator car.

[0106] The embodiment adds a condition for limiting that when a passenger views a registered and illuminated floor button on the car control box, he may give up viewing and registering because the button is blocked by a second passenger. Therefore, it is necessary to remind the first passenger to register the destination floor.

[0107] Example 12

[0108] This embodiment further adds new reminder conditions based on embodiment 7. The reminder conditions also include:

[0109] Condition 21: the second number of passengers is greater than a second threshold, or the ratio of the second number of passengers to the rated passenger capacity of the elevator car is greater than a third threshold, or the congestion level of the elevator car exceeds a threshold.

[0110] Condition 21 essentially limits: when the first passenger enters the car, there are many second passengers in the car and the car is relatively crowded. On the one hand, the first passenger may not be able to move to the control box to register the destination floor due to the crowded car. On the other hand, he may also take chances and think that with so many passengers, there must be a second passenger with the same destination floor as himself and who has already registered the destination floor. In this way, the first passenger is likely to give up the destination floor registration operation. Therefore, it is necessary to remind the first passenger to perform the destination floor registration operation.

[0111] Example 13

[0112] This embodiment provides further supplementary explanation based on the embodiment 1.

[0113] The first passenger is a passenger who rides the elevator in reverse, and the given time period is a time period starting from the moment when the passenger actually expects the direction of riding to be consistent and having a length that is a pre-specified length parameter.

[0114] If the passenger in the car does not leave the elevator car after the elevator reverses its running direction, the reminder method determines that the passenger is riding the elevator in the reverse direction, and uses the reversed elevator running direction as the passenger's actual desired riding direction.
