Description

Technical Field

[0001] This invention relates to the field of elevators, and more specifically to an elevator visual indication system for providing visual guidance to passengers. Background Technology

[0002] Reference 1 (CN115397757A) proposes a scheme based on image recognition to determine the destination floor for passengers from multiple possible destination floors, such as... Figure 1-3 As shown, this solution projects a first visual indication containing the passenger's possible destination floor near the door device when it detects a passenger approaching. Then, based on the passenger's travel route, it determines the passenger's selected destination floor and projects the corresponding elevator sign near the passenger. This solution requires no action from the passenger; they only need to adjust the destination floor signs along their travel path to select their destination floor. The elevator control system then provides a responsive elevator based on the passenger's selected destination floor.

[0003] However, the scheme in Reference 1 has an important area for improvement: when generating an elevator call signal for the destination floor selected by the passenger, two methods are used to handle the identification of the responding elevator: one is to specify the correspondence between the destination floor and the elevator identification when the passenger selects the destination floor, that is, to specify that the elevator with that identification should respond to the destination floor, and the elevator control system controls the elevator corresponding to that identification as the responding elevator to respond to the call signal of the destination floor; the other is that the elevator generates a call signal based on the destination floor selected by the passenger, the elevator control system assigns a responding elevator to the call signal of the destination floor and provides the identification of the responding elevator, and the visual indication system then displays the elevator identification to the passenger. In the first method, the possible destination floor and the corresponding elevator are simultaneously provided to the passenger. The passenger selects a destination floor and also specifies the responding elevator. Although the elevator control system can control the specified responding elevator to respond to the selected destination floor, the correspondence between the destination floor and the responding elevator may not satisfy at least one of the optimization principles, including lowest energy consumption, highest operating efficiency, and shortest passenger waiting time, because the operating information of each elevator is not considered when specifying the destination floor. In the second method, the passenger only selects the destination floor. The elevator control system allocates a responding elevator based on the passenger's selected destination floor and provides the responding elevator's identifier to the visual indication system. The visual indication system then provides the elevator identifier to the passenger. This process obviously involves multiple information interactions between the elevator control system and the visual indication system, making the steps more complex. Most importantly, because the responding elevator is unknown when providing the passenger with the possible destination floor, the proper correspondence between the possible destination floor and the actual elevator location cannot be guaranteed. This may lead to situations such as... Figure 3In this scenario, a passenger selects café 8 (located on the far left, corresponding to elevator A in relative position). However, the elevator control system assigns elevator D to café 8 instead of elevator A. Therefore, the passenger needs to move slightly to the left after passing through the door to select café 8, and then slightly to the right towards elevator D. Thus, while Reference 1 solves the problem of selecting multiple destination floors for passengers, it suffers from shortcomings such as suboptimal elevator allocation and poor passenger movement routes.

[0004] Therefore, how to enable passengers to conveniently select their destination floor while ensuring smooth passenger movement and optimal elevator allocation has become a pressing technical problem. Summary of the Invention

It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary embodiments to those skilled in the art.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0050] Example 1

[0051] As attached Figure 4 As shown, the elevator visual indication system of the present invention includes:

[0052] First detection unit: used to detect passengers entering the waiting hall who are about to take the elevator;

[0053] Destination floor determination unit: When the first detection unit detects a passenger who is about to take the elevator, it determines at least two possible destination floors for the passenger;

[0054] Virtual dispatching unit: Assuming there is a call signal with the possible destination floor as the destination floor, it dispatches each elevator based on the current elevator operation information and outputs virtual dispatching results. The virtual dispatching results include at least the possible destination floor and its responding elevator.

[0055] Storage unit: Used to store the location of each elevator in the elevator lobby;

[0056] Identifier Location Determination Unit: Used to determine the position of the identifier of the possible destination floor in the first visual indication based on the virtual allocation result and the position of the elevator in the waiting hall, and use it as the destination floor identifier position;

[0057] Visual indication generation unit: generates a first visual indication based at least on the target layer identifier position;

[0058] Providing unit: for providing the first visual indication to the passenger.

[0059] The first detection unit here can be a camera and its processing unit installed in the elevator lobby, which uses the captured images and videos to process and determine whether a passenger has entered the detection area; it can also be a device linked to the elevator, such as a turnstile installed near the elevator, which provides relevant information to the elevator visual indication system of the present invention after the passenger passes through the turnstile, thereby determining that the passenger is approaching the elevator; it can also be a device such as a mobile terminal carried by the passenger, which determines that the passenger is approaching the elevator by detecting the distance between the mobile terminal, etc. The present invention does not limit the specific implementation of the first detection unit here.

[0060] For the destination floor determination unit used to determine the possible destination floor of a passenger, it is only necessary to determine the possible destination floor of the passenger when the first detection unit detects that the passenger is about to take the elevator. There are no restrictions on the specific implementation device and method. For example, it can detect the passenger's identity information or attribute information (such as gender, age, height, etc.) and determine the possible destination floor based on the passenger's identity information or attribute information; it can also determine the possible destination floor of the passenger based on the current time and historical operating data through statistical, machine learning and other processing methods, etc.

[0061] The virtual dispatch unit assumes the existence of elevator call signals with the passenger's current floor as the departure floor and all possible destination floors as the destination floors. For these call signals, it uses the current operating information of each elevator and employs a group management algorithm to select a responding elevator from among the elevators for each call signal. No restrictions are placed on the group management algorithm; any existing group management algorithm can be used, as long as it can allocate responding elevators to these call signals. The virtual dispatch unit outputs each call signal and its corresponding responding elevator.

[0062] Identifier Location Determination Unit: Used to determine the position of the identifier of the possible destination floor in the first visual indication based on the virtual allocation result and the position of the elevator in the waiting hall, and use it as the destination floor identifier position;

[0063] The identifier location determination unit first determines the responding elevator corresponding to each call signal based on the virtual dispatch results, i.e., establishing a correspondence between the destination floor identifier and the responding elevator; then, based on the elevator positions in the waiting hall stored in the storage unit, it determines the position of each responding elevator in the first visual indication, i.e., establishing a correspondence between responding elevators and positions (the position of the responding elevator identifier in the first visual indication corresponds to the position of the responding elevator in the elevator waiting hall, i.e., the position of a certain responding elevator identifier relative to other responding elevator identifiers in the first visual indication corresponds to the position of that responding elevator relative to other responding elevators in the elevator waiting hall); finally, based on the correspondence between the destination floor identifier and the responding elevator, and the correspondence between the responding elevator and the position, it obtains the correspondence between the destination floor identifier and the position. This determines the position of the destination floor identifier in the first visual indication.

[0064] The visual instruction generation unit generates the first visual instruction in three main ways:

[0065] Method 1: Generate the first visual indication based on the target layer identifier position determined by the identifier position determination unit.

[0066] The main idea is to determine the relative positions of the destination floor identifiers of each possible destination floor in the first visual indication based on their positions in the first visual indication. Then, the first visual indication is constructed using the destination floor identifiers of each possible destination floor, so that the relative positions of the destination floor identifiers of each possible destination floor in the first visual indication are consistent with the relative positions of the responding elevators of each possible destination floor in the elevator waiting hall.

[0067] by Figure 1For example, suppose a passenger's possible destination floors are the cafe on the 8th floor, the spa on the 10th floor, and the conference room on the 4th floor. The building has four elevators: A, B, C, and D. The virtual dispatch result is: elevator A for the cafe on the 8th floor, elevator B for the spa on the 10th floor, and elevator D for the conference room on the 4th floor. Since elevators A, B, C, and D are arranged from left to right, and the elevators for the cafe, spa, and conference room are positioned from left to right in the waiting area, the destination floor markers are also arranged from left to right accordingly. Preferably, because elevator C separates the elevators for the spa on the 10th floor and the conference room on the 4th floor, the spacing between the destination floor markers corresponding to the spa on the 10th floor and the conference room on the 4th floor is slightly larger than the distance between adjacent destination floor markers of the elevators (i.e., the distance between destination floor markers corresponds roughly to the distance between the positions of the elevators in the waiting area). The key point here is the relative position of possible destination floors (e.g., the responding elevator for the 4th-floor conference room is to the right of the responding elevator for the 10th-floor spa, and the responding elevator for the 8th-floor café is to the left of the responding elevator for the 10th-floor spa; correspondingly, the destination floor sign for the 4th-floor conference room is to the right of the destination floor sign for the 10th-floor spa, and the destination floor sign for the 8th-floor café is to the left of the destination floor sign for the 10th-floor spa). This arrangement allows passengers to move to the corresponding responding elevator with minimal turning after selecting their destination floor, and since the responding elevators for possible destination floors are allocated based on elevator operation information, the allocation result is also optimal.

[0068] For example Figure 1 The elevator arrangement shown may be similar to the arrangement of the destination floors in the elevator lobby. For example, if elevators A, B, C, and D are arranged in a straight line, the destination floors may also be arranged in a straight line in the first visual indication. The two are roughly parallel, and the position of the destination floor sign in the first visual indication corresponds to the position of the corresponding elevator in the elevator lobby.

[0069] Obviously, the above description applies to Figure 5 The elevator arrangement shown.

[0070] Method 2: Generate a first visual indication based on the destination floor sign location determined by the sign location determination unit and the passenger's location.

[0071] This method is a further optimization based on Method 1. Method 1 only requires that the relative positions of possible destination floor markers correspond to the relative positions of the responding elevators. For example, in the example of Method 1, since the elevators are arranged in a straight line from left to right, the first visual indication only limits the left and right positions of the possible destination floor markers, without restricting their direction perpendicular to the elevator line. This method further considers the passenger's location. By connecting the passenger's location with the responding elevator using straight lines or curves, the passenger's movement path from their location to the responding elevator is obtained. While ensuring the left-right positional relationship of the destination floor markers (approximately, not necessarily very precise), the destination floor marker is positioned on the passenger's movement path to the responding elevator corresponding to that destination floor marker. This ensures that the passenger can pass through the destination floor marker without any adjustments to their movement path. Preferably, the possible destination layer markers are positioned on the movement path such that the distance between the possible destination layer markers and the passenger's location is approximately equal (in which case the possible destination layer markers are arranged in an arc in the first visual indication), or the possible destination layer markers are positioned on the movement path such that the distance between the possible destination layer marker corresponding to the highest probability is the shortest and the passenger's location, thereby making the possible destination layer marker corresponding to the highest probability more prominent in position and easier for the passenger to notice, so that the passenger can complete the selection of the possible destination layer marker with the highest probability as early as possible.

[0072] Method 3: The target layer identifier position is determined by the identifier position determination unit, and the first visual instruction is generated based on the passenger's location and the spatial position of the providing unit relative to the passenger's location when the first visual instruction is provided to the passenger.

[0073] This method is a further optimization based on method 2. For example... Figure 1 The elevator arrangement shown has a minimum size requirement to ensure that the destination floor signs are easily identifiable by passengers; therefore, the signs cannot be too small. When each elevator is arranged as shown in the attached diagram... Figure 1When arranged in the indicated direction, the further the first visual indicator is from the passenger elevator, the larger the available size of the possible destination floor indicator; conversely, the closer it is to the passenger, the smaller the available size. Therefore, given this minimum size, the distance between the first visual indicator and the passenger's location cannot be too small; that is, there exists a minimum distance between the first visual indicator and the passenger's location determined by the minimum size of the possible destination floor indicator. On the other hand, when the distance between the first visual indicator and the passenger's location exceeds this minimum distance, the possible destination floor indicator can remain at its minimum size, increase accordingly, or increase the distance between the possible destination floor indicators. This provides the visual indicator generation unit with design freedom in generating the first visual indicator. If the first visual indicator composed of possible destination floor indicators is considered as a whole, the visual indicator generation unit can determine, within a certain range, the spatial position relative to the passenger's location when the providing unit provides the first visual indicator to the passenger. This spatial position should ensure that the possible destination floor indicators are not smaller than their minimum size without overlapping. When the spatial location causes the possible destination layer markers to exceed their minimum size without overlapping, the visual indication generation unit can appropriately determine the size of the possible destination layer markers, the spacing distance, the distance between the first visual indication and the passenger's location, and minor adjustments to their relative positions (without changing the approximate relative positional relationship, such as the aforementioned left and right adjacency).

[0074] Preferably, the first visual identifier also includes various movement paths.

[0075] Example 2

[0076] This embodiment further explains the virtual allocation unit based on Embodiment 1.

[0077] In this embodiment, the destination layer determination unit determines the likelihood of a passenger selecting the possible destination layer while determining the possible destination layer.

[0078] After obtaining the probability of a possible destination floor being selected, the dispatching algorithm used by the virtual dispatching unit to dispatch each elevator includes:

[0079] Algorithm 1: When the number of possible destination floors does not exceed the number of available elevators, the virtual dispatching unit dispatches each elevator according to the following steps so that each possible destination floor corresponds to a different response elevator (only the first visual indication is needed, and there is no need for a second visual indication when multiple possible destination floors correspond to the same response elevator):

[0080] Step A1: Construct call signals for each possible destination floor;

[0081] Step A2: Select an unselected call signal from all call signals and use it as the selected call signal;

[0082] Step A3: Select one of the elevators that has not been selected as the responding elevator for the selected call signal;

[0083] Step A4: Determine if there are still any unselected elevator call signals. If yes, return to step A2; otherwise, proceed to step A5.

[0084] Step A5: Output the possible destination floors and responding elevators corresponding to each elevator call signal as dispatch results.

[0085] Since the number of possible destination floors does not exceed the number of available elevators, and step A3 selects the responding elevator for the selected call signal from all elevators that have not been selected, this process ensures that each possible destination floor will necessarily correspond to a different responding elevator.

[0086] Algorithm 2: The virtual dispatch unit dispatches each elevator according to the following steps:

[0087] Step B1: Construct call signals for each possible destination floor;

[0088] Step B2: Select an unselected call signal from all call signals and use it as the selected call signal;

[0089] Step B3: Select one of the elevators from all the elevators as the responding elevator for the selected call signal;

[0090] Step B4: Determine if there are still any unselected elevator call signals. If yes, return to step A2; otherwise, proceed to step A5.

[0091] Step B5: Output the possible destination floors and responding elevators corresponding to each elevator call signal as dispatch results.

[0092] The difference between Algorithm 2 and Algorithm 1 lies in step B3, which selects the responding elevator from all elevators for a chosen call signal. This means that the responding elevator for a chosen call signal may correspond to multiple chosen call signals simultaneously. The advantage of this is that the range of selectable elevators for the subsequently allocated call signals is larger than that of Algorithm 1, resulting in better evaluation metrics for the responding elevators. However, the disadvantage is that multiple possible destination floors may correspond to the same responding elevator, which can complicate the generation of the first visual indication and the passenger selection process, as described in subsequent embodiments.

[0093] Preferably, step A2 or B2 prioritizes selecting the target layer with the highest probability from all possible target layers.

[0094] To combine the advantages of both Algorithm 1 and Algorithm 2, Algorithm 2 can be slightly modified to obtain:

[0095] Algorithm 3: The virtual dispatch unit dispatches each elevator according to the following steps:

[0096] Step C1: Construct call signals for each possible destination floor;

[0097] Step C2: Select an unselected call signal from all call signals and use it as the selected call signal;

[0098] Step C3: Determine if there are still elevators that have not been selected. If so, select an elevator that has not been selected as the elevator that responds to the selected call signal. Otherwise, select one of the elevators that has been selected as the elevator that responds to the selected call signal.

[0099] Step C4: Determine if there are still any unselected elevator call signals. If yes, return to step C2; otherwise, proceed to step C5.

[0100] Step C5: Output the possible destination floors and responding elevators corresponding to each elevator call signal as dispatch results.

[0101] To ensure that the responding elevator for the most likely destination floor has the best group management evaluation index, step C2 in the above algorithm prioritizes selecting the destination floor with the highest probability from all possible destination floors (the more elevators available, the better the evaluation index of the dispatched responding elevator). Furthermore, when multiple possible destination floors correspond to the same responding elevator, the visual indication generation unit displays the identifiers of all possible destination floors corresponding to the same responding elevator at the location of that responding elevator.

[0102] Considering that providing multiple possible destination floor markers simultaneously for the same responding elevator location (based on virtual allocation results) could lead to the markers being too small for passengers to easily identify, the visual indication generation unit further generates a second visual indication containing multiple possible destination floors corresponding to the same responding elevator.

[0103] Preferably, the providing unit displays the second visual indication on the path from the first visual indication to the responding elevator and between the first visual indication and the responding elevator, or on the path from the passenger's current location to the responding elevator and between the passenger's current location and the responding elevator.

[0104] Preferably, when generating the second visual indication, the visual indication generation unit ensures that multiple possible destination floors corresponding to the same responding elevator are approximately on the same straight line, and that the straight line is approximately perpendicular to the path.

[0105] The providing unit provides a second visual instruction while providing a first visual instruction to the passenger, or provides a second visual instruction after a certain delay after providing the first visual instruction; preferably, the first visual instruction is stopped when the second visual instruction is started or after a certain period of time after the second visual instruction is started.

[0106] Example 3

[0107] This embodiment is similar to the previous embodiment; here, only the differences between this embodiment and the previous embodiment will be described.

[0108] In this embodiment, the elevator visual indication system further includes:

[0109] The second detection unit is used to detect the destination floor identifier selected by the passenger from the possible destination floors using the visual indication and to take the floor corresponding to the identifier as the selected destination floor.

[0110] Elevator call command generation unit: After the second detection unit outputs the selected destination floor, it generates a control command based on the selected destination floor and the virtual dispatch result and sends it to the elevator control system. The control command is an instruction to control the responding elevator corresponding to the selected destination floor to carry out the passenger transport.

[0111] The elevator call command generation unit further includes:

[0112] Query module: Uses the selected destination floor to query the corresponding elevator from the virtual dispatch results;

[0113] First generation module: used to generate a first instruction to control the response elevator corresponding to the selected destination floor to move from its current floor to the passenger's current floor;

[0114] Second generation module: used to generate a second instruction to control the response elevator corresponding to the selected destination floor to move from the passenger's current floor to the selected destination floor after the door is closed;

[0115] Merging and sending module: integrates the first instruction and the second instruction together and sends the integrated result to the elevator control system.

[0116] For the second detection unit, this embodiment does not impose any restrictions on its specific implementation, as long as it can detect and obtain the selected destination floor chosen by the passenger. For example, the second detection unit can be a camera and its processing module. The processing module uses the passenger's position or movement information captured by the camera to determine the possible destination floor markers that the passenger may pass through during the movement using image recognition and other methods, and outputs the determination result to provide the destination floor selected by the passenger. The second detection unit can also be a location-based system such as an indoor positioning system or multiple distance detection units that can detect the distance between the passenger's mobile terminal and the detection unit. The passenger's position information is obtained by using the distance or distance and angle information detected by two or more distance detection units. The passenger's position information is compared with the position information of each possible destination floor marker in the first visual indication. When the passenger's position is the same as the position of the possible destination floor marker or the distance between the two is less than a threshold, it is determined that the passenger is located at the destination floor marker. Based on this, it is determined that the passenger has selected the destination floor marker, and thus the possible destination floor marker is used as the selected destination floor and output.

[0117] In addition, after the second detection unit detects and outputs the passenger's selection result, the visual indication generation unit determines whether the passenger's selection corresponds to multiple possible destination layers. If so, it further generates a second visual indication; otherwise, it does not perform the operation of generating a second visual indication.

[0118] After the visual instruction generation unit generates the second visual instruction, the providing unit then provides the second visual instruction to the passenger. The processing method for whether to provide both the first and second visual instructions simultaneously, or whether to provide the first visual instruction only when the second visual instruction is provided, is the same as in the aforementioned embodiments.

It will also be understood that, unless expressly defined herein, terms such as those defined in a general dictionary shall be interpreted as having the meaning consistent with their meaning in the relevant field context, and not as having an idealized or overly formal meaning.
