Description

TECHNICAL FIELD

[0001] The present application relates to the elevator technical field, specifically to a kind of lift guiding mark system. BACKGROUND

[0002] Document 1 (CN114981194B) discloses an elevator guiding device, which displays a guiding direction mark on the path from the start position of the recognized user to the landing of the selected elevator, and the display mode of the guiding direction mark is different from the display mode used for displaying the guiding direction mark for other users. However, the solution of document 1 has the following disadvantages:

[0003] 1. Since the display mode of the guiding direction mark is corresponding to the elevator user (the reasons include: A, the document 1 states that the display mode is registered corresponding to the identification information of each user, the identification information is the information read by the information reading part G11, G21 from the magnetic card, IC card or tag device carried by the user to identify the user, and the identification information is also used by the user authentication part 21 as the basis for identifying whether the user has access rights; B, in the specification

[0032] section, it is described that "in the second database DB2, the display mode of the guiding direction mark for each user is registered corresponding to the identification information of the user. The display mode of the guiding direction mark is automatically or manually set for each user in advance". Therefore, the identification information can be understood as the identity information of the user, but it is not the identification information of the information reading part G11, G21), and the display mode is not repeated for different elevator users. Therefore, for the two elevator users who pass through the gate and respond to the elevator, different display modes are used to display the guiding direction marks for the two elevator users. Since the guiding direction mark is continued from the start position to the responding elevator, when the guiding direction mark for the later elevator user is displayed, the guiding direction mark for the later elevator user will cover or mix with the guiding direction mark for the former elevator user, which will obviously change the guiding direction mark between the current position of the former elevator user and the responding elevator, causing confusion and discomfort to the former elevator user. On the other hand, since different display modes are used for each elevator user, a large number of display modes need to be established in advance, which increases the difficulty of selecting non-repeating display modes from a large number of display modes to ensure non-repetition;

[0004] 2、From the description of

[0038] section, it can be known that the display control unit starts to display the guide direction mark for the user when the user passes through the security gate, and ends to display the guide direction mark for the user after the response elevator arrives. It can be easily imagined that, between the first time when the preceding user passes through the gate and the second time when the response elevator arrives at the floor where the preceding user is located, if there is a following user passing through the gate, the display of the guide direction mark for the preceding user will continue to exist (see the guide mark S1 for the user H1 in the middle), and the display of the guide direction mark for the following user will adopt the display mode which is not used for the display of the guide direction mark for the preceding user, which will increase the risk of the intersection of the guide direction mark for the preceding user and the guide direction mark for the following user, secondly, will increase the number of display modes which need to be established in advance, and thirdly, will increase the number of guide direction marks which exist at the same time (i.e. the number of guide direction marks displayed on the ground of the waiting hall, so that the display content on the ground is in a mess, and even if there is no intersection, the identification difficulty of the passengers will also be increased). Figure 2

[0005] Therefore, how to reduce the number of display modes which need to be established in advance, how to reduce the risk of the intersection of the guide direction marks for different passengers, and how to reduce the identification difficulty of the passengers for the guide marks become a technical problem to be solved under the condition that the display mode of the guide direction mark for the user (i.e. the passenger) is not repeated.

[0064] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application. It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0065] Embodiment 1

[0066] As Figure 1 shown, the embodiment provides a lift guiding mark system, which includes an acquisition module, a generation module, a control module and a mark presentation device. The acquisition module is used to acquire device information of a lift signal registration device operated by a passenger when registering a lift signal and response elevator information of a response elevator allocated by an elevator group control system for the passenger, wherein the device information at least includes device ID of the lift signal registration device, and the response elevator information at least includes elevator ID of the response elevator; the generation module is used to generate a guiding mark for guiding the passenger to a location where the response elevator is located according to specific information, wherein the specific information includes the device information and the response elevator information; the control module is used to control presentation of the guiding mark, including whether to present and a presentation mode adopted when presenting; and the mark presentation device is used to present the guiding mark to the passenger under control of the control module.

[0067] The acquisition module further includes a device information acquisition unit and a response elevator information acquisition unit, the device information acquisition unit is used to acquire device information of the lift signal registration device operated by the passenger when registering the lift signal from the lift signal registration device (such as device ID of the lift signal registration device, i.e. which lift signal registration device the lift signal is from), and the response elevator information acquisition unit is used to acquire response elevator information of the response elevator allocated by the elevator group control system for the passenger (i.e. the lift signal) from the elevator group control system (such as elevator number, ID, etc., i.e. number or ID of the elevator selected by the elevator group control system from elevators E1-E6 configured in the building to respond to the passenger or the lift signal).

[0068] It should be noted that in engineering practice, the time required for the elevator group control system to receive the call signal registered by the passenger using the call signal registration device to determine and output the responding elevator is usually much shorter than the time interval between the generation time of two adjacent call signals (or the registration time of the call signal registered by any two passengers using the call signal registration device). Therefore, the acquisition module can easily determine the correspondence between the device information and the responding elevator (i.e., the device information and the responding elevator corresponding to the same call signal), and send it to the generation module in a manner that can reflect this correspondence (e.g., combine the determined device information and the responding elevator as a piece of information). It should be noted that the call signal registration device is defined from the perspective of functional implementation, rather than the specific physical implementation in engineering. Therefore, the call signal registration device can be a gate usually installed at the entrance of a building (which needs to be equipped with an identity acquisition device such as a card reader, iris scanning device, etc. for reading the passenger's identity information, and can determine the passenger's floor access permission and determine the destination floor for him / her according to the passenger's identity information; it can also be a destination floor registration device installed at different entrances of the waiting hall, etc. The specific implementation of the call signal registration device is not limited in this application, as long as it can obtain the passenger's destination floor information and different call signal registration devices have different device information (hereinafter referred to as device ID). The responding elevator information acquisition unit not only acquires the elevator ID of the responding elevator, but also acquires the running information of the responding elevator (to determine whether the car is stopped at the passenger's floor), and sends the running information of the responding elevator to the presentation mode selection unit of the control module.

[0069] The generation module further includes an identification starting point determination unit, an identification ending point determination unit, a position information storage unit, and an identification generation unit. The identification starting point determination unit is used to determine the starting point of the guide identification, and the identification ending point determination unit is used to determine the ending point of the guide identification. The position information storage unit is used to store a first correspondence relationship between the device ID and the device position of the call signal registration device, and a second correspondence relationship between the elevator ID and the elevator position of the elevator. The identification generation unit is used to generate the guide identification according to the identification starting point and the identification ending point.

[0070] The identification start point unit determines the device position where the device corresponding to the device ID registers the elevator signal according to the device ID and the first correspondence relationship, and determines the device position as the start point of the guide identification. The identification end point unit determines the elevator position of the responding elevator according to the responding elevator information (here, the elevator ID of the responding elevator) and the second correspondence relationship, and determines the elevator position of the responding elevator as the end point of the identification. The identification generation unit generates the guide identification according to the identification start point and the identification end point, and the guide identification has the identification start point and the identification end point as the end points, and points from the identification start point to the identification end point (such as the arrow located at the identification end point). In theory, the guide identification generated by the identification generation unit can be any broken line or curve connected to the identification start point and the identification end point, and is preferably substantially in the shape of a long strip, a line or a strip.

[0071] The identification generation unit generates the guide identification according to the following steps:

[0072] Step S1, connecting the identification start point and the identification end point to obtain a straight line segment;

[0073] Step S2, determining the direction of the boundary straight line of the waiting hall (usually a rectangle, so there are two directions);

[0074] Step S3, judging whether the straight line segment is parallel to one of the two directions, if yes, taking the straight line segment as the guide identification and ending, otherwise, entering the next step;

[0075] Step S4, taking one of the start point and the end point of the guide identification as a first point, and taking the other of the start point and the end point of the guide identification as a second point;

[0076] Step S5, drawing a first parallel line of the first direction of the two directions through the first point;

[0077] Step S6, drawing a perpendicular line of the parallel line through the second point to obtain a foot;

[0078] Step S7, taking an optional point (preferably the first foot) between the first point and the foot as a new first point;

[0079] Step S8, drawing a parallel line of the other direction of the two directions different from the first direction through the first point;

[0080] Step S9, judging whether the second point is located in the parallel line, if yes, sequentially combining the straight line segments between the first point and the second point, and taking the combination result as the guide identification and ending, otherwise, replacing the first direction with the other direction of the two directions different from the first direction, and returning to step S5.

[0081] Preferably, step S9 connects the adjacent two line segments by a circular arc after sequentially combining the straight line segments between the first point and the second point, and the circular arc has a center located at one side of an acute angle formed by the adjacent two line segments, and the combination of the straight line segments and the part of the circular arc between the two straight line segments is taken as the combination result. Further preferably, the longer the length of the shorter straight line segment among the adjacent two line segments, the greater the radius of the circular arc.

[0082] Preferably, step S9 performs step A one or more times after sequentially combining the straight line segments between the first point and the second point; the step A is: selecting a point on each of the first straight line segment and the second straight line segment, then connecting the two points by a straight line to obtain a third straight line segment; the first straight line segment, the second straight line segment and the third straight line segment combine to form a triangle, and the remaining two sides other than the third straight line segment in the triangle are deleted to obtain the remaining part of the first straight line segment and the second straight line segment and the third straight line segment.

[0083] The first straight line segment and the second straight line segment are sequentially combined one or more times, and the remaining part of the first straight line segment and the second straight line segment and the third straight line segment which have performed the step A operation and the remaining straight line segments which have not performed the step A operation are sequentially combined, and the combination result is taken as the guide mark. The purpose is to avoid that the above steps all obtain horizontal or vertical paths, but obtain paths in different directions, thereby being beneficial to shorten the length of the guide mark, and also conforming to the actual habits of people.

[0084] The control module comprises a presentation termination determination unit and a control unit; the presentation termination determination unit is used to determine whether to make the mark presentation device stop the presentation of the guide mark; the control unit receives the guide mark from the mark generation unit, and generates a control instruction according to the determination result of the presentation termination determination unit, so that the mark presentation device presents the guide mark under the control of the control instruction when the presentation termination determination unit does not output a presentation termination instruction, and stops the presentation when the presentation termination determination unit outputs the presentation termination instruction.

[0085] The presentation termination determination unit determines whether to present the guide mark in various ways:

[0086] Method 1: the presentation termination determination unit determines whether to terminate the presentation of the guide mark according to the position relationship of the response elevator, and does not output a presentation termination instruction when the response elevator arrives at the floor where the passenger is located; outputs a presentation termination instruction when the response elevator arrives at the floor where the passenger is located.

[0087] The second mode is that the presentation termination determining unit determines whether to terminate the presentation of the guide mark according to the position information of the passenger, and does not output the presentation termination instruction until the passenger moves to the waiting area of the responding elevator. When the passenger moves to the waiting area of the responding elevator, the presentation termination determining unit outputs the presentation termination instruction. The position of the passenger is not limited here, and can be determined directly according to the detection result of the detection device (for example, a camera arranged in the waiting hall is used to take a picture, and then the position of the passenger is obtained through image processing to determine whether the passenger has moved to the waiting area of the responding elevator), or can be estimated, for example: 1) according to the time between the registration time of the passenger registering the call signal (i.e. the time when the acquisition module acquires the device information or the responding elevator information) and the current time, and then multiplying the average walking speed of the passenger by the moving distance of the passenger, and then determining whether the passenger has moved to the waiting area of the responding elevator according to the size relationship between the total length of the guide mark and the moving distance (usually, the difference between the two is calculated, and then the relationship between the difference and a threshold is determined); 2) according to the total length of the guide mark to determine the moving time of the passenger from the device position of the call signal registration device to the elevator position of the responding elevator, and then determine the time between the registration time of the passenger registering the call signal (i.e. the time when the acquisition module acquires the device information or the responding elevator information) and the current time, and then determine whether the passenger has moved to the waiting area of the responding elevator according to the size relationship between the moving time and the time (usually, the difference between the two is calculated, and then the relationship between the difference and a threshold is determined).

[0088] The specific implementation mode of the identification presentation device is not limited in the embodiment, as long as the guide mark can be presented to the passenger. In engineering practice, the identification presentation device can be a projection device arranged on the top of the waiting hall (which projects the guide mark onto the ground of the waiting hall), or a display device installed on the ground of the waiting hall (which displays the guide mark on the ground of the waiting hall). Hereinafter, the projection device is taken as an example to project the guide mark onto the ground of the waiting hall.

[0089] It should be noted that although the present embodiment and document 1 both involve the generation of guide marks (document 1 describes the generation of images of path guide marks), there are essential differences between the two. As can be seen from document 1 specification

[0034] paragraph, the basis for generating guide marks is the identification information of the user, the identification information of the security gate and the selected elevator information; in the present embodiment, the generating unit generates guide marks according to device information (determined mark starting point information) and response elevator information (determined mark end point information), and the device information corresponds to the identification information of the security gate in document 1, and the response elevator information corresponds to the selected elevator information in document 1. Obviously, the basis for generating guide marks in document 1 has the user's identification information in addition to the basis for generating guide marks in the present embodiment, and the user's identification information cannot be obtained in many scenarios, so the technical solution of the present embodiment has a wider scope of application than document 1. The fundamental reason for the present embodiment to simplify the user's identification information compared to document 1 in the basis for generating guide marks is that the present embodiment realizes that the fundamental difference between guide marks is that the essence of guide marks is to connect the device location of the call registration device and the elevator location of the response elevator, and this connection is only determined by the two end points of the connection (i.e. the device location and the elevator location), and has nothing to do with the user, such as: for users who take the elevator at different times, when the call registration device operated by the user and the response elevator allocated by the elevator control system are the same, although the identification information of the two users is necessarily different, the guide marks (i.e. the images of path guide marks in document 1) generated for them can be the same or different, i.e. the identification information of the user cannot affect the generation of guide marks by the generating module, so the identification information of the user cannot be used as the basis for generating guide marks. It is through such in-depth analysis, understanding and cognitive results that the present embodiment can simplify the user's identification information in the basis for generating guide marks in document 1 to obtain the guide mark generation scheme in the present embodiment, and provide a method for generating guide marks only according to device location and elevator location, thereby expanding the scope of application and reducing the complexity of the processing logic and processing load of the generating module for generating guide marks.

[0090] Embodiment 2

[0091] The present embodiment is based on the foregoing embodiments and further describes the generation of guide marks by the generating module.

[0092] In the foregoing embodiment, the identification starting point determination unit takes the device position of the passenger-operated call signal registration device embodying the device information as the starting point of the guide identification, and the guide identification remains unchanged until the presentation termination determination module outputs the presentation termination instruction, that is, the identification starting point remains at the device position throughout the presentation. Such a processing manner has a disadvantage that when there are many passengers in the waiting hall and the presentation device presents a large number of guide identifications, if the generation module needs to generate a guide identification for passenger A at this time, the risk of the guide identification of passenger A intersecting with the existing guide identifications in the current waiting hall will be very high (and because the number of presented identifications is too large, it will also be messy, which will also bring inconvenience and difficulty to the identification of passengers), and therefore how to reduce the risk of the guide identification generated by the generation module for a passenger intersecting with the existing guide identifications in the current waiting hall has become a technical problem to be solved. For this purpose, the present embodiment proposes that the identification starting point determination unit not only determines the starting point of the identification according to the device information, but also adjusts the identification starting point according to the passenger position, thereby forming a guide identification with a constantly changing starting point.

[0093] Specifically, the acquisition module acquires real-time position information of the passenger; the identification starting point determination unit determines the identification starting point according to the real-time position information of the passenger; the identification terminal point determination unit determines the elevator position of the response elevator according to the elevator ID of the response elevator and the second correspondence relationship, and takes the elevator position of the response elevator as the identification terminal point; the identification generation unit generates the guide identification according to the identification starting point and the identification terminal point, and the guide identification takes the identification starting point and the identification terminal point as the end points respectively, and is directed from the identification starting point to the identification terminal point.

[0094] The identification presentation device presents only the guide identification located between the real-time position of the passenger and the elevator position under the control of the control module (this guide identification is actually the complete guide identification taking the real-time position of the passenger at the current time as the starting point and the elevator position as the terminal point.), and no longer presents the previous guide identification located between the device position and the real-time position of the passenger (this guide identification is actually the part of the guide identification taking the real-time position of the passenger at the previous time as the starting point and the elevator position as the terminal point located between the device position and the real-time position of the passenger at the current time. Please refer to the description for details.).

[0095] As Figure 3As shown, when the passenger moves towards the responding elevator, the starting point of the presented guiding mark moves forward constantly along with the passenger's movement, so that the position of the guiding mark after the passenger passes no longer presents the guiding mark, which is equivalent to releasing the area originally used for presenting the guiding mark for the presentation of the guiding mark of the subsequent passenger (since the passenger is moving towards the responding elevator, the guiding mark behind the passenger has lost the guiding effect on the passenger, so the efficient use of the presentation area is achieved without affecting the guiding effect of the guiding mark on the passenger), which obviously can reduce the risk of the intersection of the guiding mark generated by the generation module for the subsequent passenger and the guiding mark of the present passenger.

[0096] The foregoing is to reduce the risk of the intersection of the guiding mark generated by the generation module for the subsequent passenger and the guiding mark of the present passenger by adjusting the starting point of the guiding mark in real time, and next, a method of reducing the risk of the intersection of the guiding mark generated by the generation module for the subsequent passenger and the guiding mark of the present passenger by adjusting the end point of the guiding mark in real time (the method is in a "and / or" relationship with the previous method of adjusting the starting point) is proposed, which is specifically:

[0097] The identification generation unit takes the current guiding mark as a preset guiding mark, and the presentation device does not directly present the preset guiding mark. Then, the starting point and / or the end point of the mark are selected in the preset guiding mark in real time, the final presented guiding mark is generated according to the starting point and the end point of the mark, and the guiding mark takes the starting point and the end point of the mark as the end points respectively and points from the starting point to the end point. The starting point and the end point of the mark are points on the preset guiding mark, the starting point of the mark is located behind the passenger who has passed, the end point of the mark is located in front of the passenger who has not passed, and the distance between the starting point and the end point of the mark and the real-time position of the passenger is less than a preset threshold.

[0098] In this way, when the passenger moves towards the responding elevator, the starting point and the end point of the mark also move forward, that is, the end point of the mark always presents a certain length of the guiding mark in front of the passenger. This method actually considers that the guiding mark far away from the passenger does not play a guiding role on the passenger, and the guiding mark within a certain distance in front of the passenger really plays a guiding role on the passenger. Therefore, this method releases the area originally used for presenting the guiding mark far away from the passenger by not presenting the guiding mark far away from the passenger, so as to reduce the risk of the intersection of different guiding marks.

[0099] Embodiment 3

[0100] This embodiment is further described on the basis of the generation of the guiding mark by the generation module according to Embodiment 1.

[0101] Although the method of adjusting the start point and / or end point of the guidance mark in real time in Embodiment 2 helps to reduce the risk of the intersection between different guidance marks, it cannot completely avoid the intersection between different guidance marks.

[0102] The generation module in Embodiment 1 only considers the generation of a single guidance mark when generating the guidance mark, and does not consider the interference between the guidance mark it is generating and the guidance marks already existing in the hall.

[0103] As shown in Figure 2 , the presentation device is a projector, E1-E6 are elevators, H1-H3 are three passengers, and S1-S3 are the guidance marks generated by the generation module for passengers H1-H3. When the guidance marks S2 and S3 intersect, if the guidance marks are as in Figure 2 (a), they intersect in a straight line without difference, and in particular when the guidance marks intersect at a non-perpendicular angle at the intersection point, the passenger needs to identify which of the two line-shaped marks with a small included angle in front of him is his guidance mark, which obviously brings inconvenience to the passenger in identification. To solve this problem, this embodiment proposes that when the mark generation unit identifies that at least two guidance marks have an intersection point, one of the guidance marks has a shape at the intersection point different from that at a non-intersection point, thereby embodying the covering relationship between different guidance marks, so as to reduce the inconvenience of the passenger in identification.

[0104] Two examples are given here: Example 1, as shown in Figure 2 (b), the continuous relationship of the guidance marks before and after the intersection point is embodied in a continuous spanning manner; and Example 2, as shown in Figure 2 (c), the continuous relationship of the guidance marks before and after the intersection point is embodied in a discontinuous manner.

[0105] When the two guidance marks can embody the covering relationship (such as in Example 1, different presentation manners are adopted and the presentation manners (such as different colors, line shapes), and in Example 2, the discontinuity of the line), the mark generation unit determines the covering relationship between the guidance marks and the covered and the coverer in any of the following manners:

[0106] Manner 1, the covering relationship between the guidance marks is determined according to the generation time of the guidance marks; the guidance mark generated earlier is taken as the covered, and the guidance mark generated later is taken as the coverer. Because the guidance mark as the coverer is easier to identify, the passenger earlier is likely to have passed the intersection point, and thus this is conducive to ensuring that the passenger later has been identified and will not affect the passenger earlier. In this manner, the generation time of the guidance mark needs to be added to the basis for the generation module to generate the guidance mark;

[0107] The method 2 is to determine the covering relationship between the guide marks according to the relative position and distance of the passenger position corresponding to the guide mark and the intersection; when some of the passengers have passed the intersection, the guide mark corresponding to the passenger who has passed the intersection is taken as the covered one; when none of the passengers has passed the intersection, the guide mark corresponding to the passenger who passes the intersection first is taken as the covering one. The order of the passengers passing the intersection is determined by the length of the guide mark between the position of the passenger and the intersection. At this time, the position information of the passenger also needs to be added in the basis for generating the guide mark by the generating module.

[0108] Embodiment 4

[0109] In the case that the starting point of the guide mark presented by the presentation device moves constantly with the movement of the passenger, the generating module can still generate the guide mark according to the steps S1-S9 described in Embodiment 1, but cannot make full use of the area originally used for presenting the first guide mark which is re-released due to the starting point of the guide mark constantly moving with the movement of the passenger. Therefore, a new guide mark generation method is proposed here,

[0110] The guide mark generation method used by the guide mark generation unit when generating the guide mark includes the following steps:

[0111] Step T1, connecting the starting point of the mark and the ending point of the mark to obtain a straight line segment;

[0112] Step T2, determining the direction of the boundary straight line of the waiting hall;

[0113] Step T3, judging whether the straight line segment is parallel to one of the two directions, if yes, taking the straight line segment as the guide mark and ending, otherwise, entering the next step;

[0114] Step T4, taking one of the starting point and the ending point of the guide mark as the first point, and taking the other one of the starting point and the ending point of the guide mark as the second point;

[0115] Step T5, making a first parallel line of the first direction of the two directions through the first point;

[0116] Step T6, making a perpendicular line of the parallel line through the second point to obtain a foot;

[0117] Step T7, taking an optional point between the first point and the foot of the perpendicular as a new first point; determining whether the first point meets the condition one, if yes, entering step T8, if not, moving a preset distance in the direction approaching the first point and taking the point as a new first point, until the new first point meets the condition one and then entering step T8, if the number of times of determination reaches a preset number of times and still cannot meet the condition one, entering step T8; the condition one is that there is no intersection between the part between the boundary of the response elevator side of the elevator hall and the first parallel line and other guide signs, the part being parallel to the parallel line passing through the first point in step T6;

[0118] Step T8, drawing two parallel lines of another direction different from the first direction through the first point;

[0119] Step T9, determining whether the second point is located in the parallel line, if yes, combining the straight line segments between the first point and the second point in turn and taking the combination result as the guide sign, ending, otherwise, replacing the first direction with another direction different from the first direction and returning to step T5.

[0120] The method can avoid the intersection points as much as possible by using the avoidance strategy.

[0121] Embodiment 5

[0122] Figure 4 Another structural schematic diagram of the elevator guiding sign system is shown. Only the differences from the embodiment 1 will be described below.

[0123] In the embodiment, the control module includes a presentation termination determination unit, a control unit, a presentation mode storage unit and a presentation mode selection unit. The presentation mode storage unit is used to store the pre-established presentation mode of the guide sign and the presentation mode of the identification presentation device, and the corresponding relationship between the guide sign and the presentation mode; the presentation mode selection unit selects a presentation mode from the presentation mode storage unit as a selected presentation mode according to the information obtained by the acquisition module; and the control unit controls the identification presentation device to generate the guide sign according to the selected presentation mode generated by the presentation generation module in the case that the presentation termination module does not output the presentation termination instruction.

[0124] The presentation mode here refers to the mode adopted by the identification presentation device to make the guide sign present different presentation effects, including but not limited to the color, thickness, shape, pattern, brightness, flashing, filling, line type, etc. of the guide sign, and the presentation mode can be simply understood as a group of control parameters determining the presentation effect.

[0125] In the embodiment, under the control of the control module, the identification presentation device presents the guide sign in the presentation mode corresponding to the guide sign to be presented (it is assumed in the embodiment that the identification presentation device is a projector projecting on the floor of the waiting hall or other appropriate positions).

[0126] Here, the presentation mode selection unit selects one presentation mode as the selected presentation mode in any of the following ways:

[0127] Way A: The presentation mode storage unit pre-stores the standard image and its presentation mode of each guide mark in association. The presentation mode selection unit compares the guide mark to be presented from the generation module with the guide mark standard image, and selects the presentation mode corresponding to the guide mark standard image closest to the guide mark to be presented as the selected presentation mode.

[0128] Way A involves image processing (image comparison), and has the disadvantage of heavy processing load. Ways B and C can overcome this disadvantage.

[0129] Way B: The presentation mode storage unit pre-stores the mark start point and end point of each guide mark, or the device information and elevator information, or the mark corresponding to the guide mark and the corresponding presentation mode in association. The presentation mode selection unit determines the presentation mode corresponding to the mark start point and end point of the guide mark to be presented from the generation module, or the device information and elevator information, or the mark corresponding to the guide mark in the presentation mode storage unit, and selects it as the selected presentation mode.

[0130] In Way B, as long as at least one of the mark start point and end point of two guide marks is different, or at least one of the device information and elevator information corresponding thereto is different, the two guide marks are regarded as different guide marks, i.e., when the mark start point and end point of two guide marks are the same, or the device information and elevator information corresponding thereto are the same, the two guide marks are regarded as one guide mark, so different marks, such as numbers, can be assigned to each guide mark whose mark start point and end point, or at least one of the device information and elevator information corresponding thereto, are different, and the guide mark can be referred to by the mark thereafter

[0131] Way C: The presentation mode storage unit pre-stores the device information and elevator information of each guide mark and the corresponding presentation mode in association. The presentation mode selection unit acquires the device information and elevator information of the guide mark to be presented from the acquisition module, and then selects the presentation mode corresponding to the device information and elevator information of the guide mark to be presented from the presentation mode storage unit according to the device information and elevator information of the guide mark to be presented, and selects it as the selected presentation mode. Way C does not require the generation module to output other information in addition to the guide mark as in Way B.

[0132] Next, how to pre-establish the guide mark and its presentation mode stored in the presentation mode storage unit will be described.

[0133] First, it is necessary to determine the number of guidance identifiers and their presentation modes that are to be pre-established in the presentation mode storage unit. The determination of the number includes:

[0134] Method 1, determine the maximum number of waiting passengers in the waiting hall at the same time, and take the maximum number as the first number. Since the role of the guidance identifier is to provide guidance service for passengers by using the guidance identifier, in order to cope with the worst case, it is necessary to provide each waiting passenger in the waiting hall with a guidance identifier, so it is natural to pre-establish the guidance identifier and its presentation mode in the presentation mode storage unit according to the maximum number of waiting passengers in the waiting hall at the same time, that is, the number of guidance identifiers and their presentation modes in the presentation mode storage unit should be no less than the maximum number of waiting passengers in the waiting hall at the same time. However, the exact value of the maximum number of waiting passengers in the waiting hall at the same time is not easy to obtain, and it will change over time.

[0135] Method 2, calculate the product of the number of call signal registration devices in the waiting hall and the number of elevators, and take the product as the first number. Because the guidance identifier is used to guide the passenger to move from the current position, i.e. the position of the call signal registration device, to the identification of the responding elevator after the call signal registration device is registered and the system determines the responding elevator, the guidance identifier corresponds to the combination of the call signal registration device and the elevator, and the number of all possible combinations is equal to the product of the number of call signal registration devices and the number of elevators.

[0136] Method 3, the maximum number of specific passengers in the waiting hall, the specific passenger is the passenger whose call signal registration device operated when registering the call signal is different from at least one of the responding elevator and the other passengers in the waiting hall.

[0137] From the above analysis of the three methods, the number of method 1 is the largest, and it is difficult to obtain a certain value (as time goes by, the use case will change, and the maximum number of waiting passengers in the waiting hall will also change); the number of method 2 is usually smaller than the number determined by method 1, and once the call signal registration device and the elevator are set, the first number obtained by method 2 will be fixed; the first number obtained by method 3 will be less than or equal to the first number obtained by method 2, but there is also uncertainty, and it is very difficult to apply in engineering practice, so method 2 is preferred.

[0138] As can be seen from paragraphs

[0025] and

[0026] of the specification of Document 1, the identification information is read by the information reading units G11 and G21 from the magnetic card, IC card or tag device carried by the user to identify the user's information, and the user authentication unit 2 authenticates whether the user identified by the identification information has access rights based on the registration information of the first database DB1. Therefore, it can be inferred that the identification information of each user is different (otherwise the access rights authentication function cannot be completed). As can be seen from paragraphs

[0030] and

[0032] of the specification of Document 1, the display method of its guidance mark (i.e. the guidance mark in this embodiment) (i.e. the presentation method in this embodiment) corresponds to the identification information of each user. From these two points, it can be seen that Reference 1 pre-establishes a display method for each possible user. However, this approach obviously has drawbacks: 1) Elevator users change frequently, making the maintenance of the database used to store user identification information and their display methods cumbersome; 2) Since it is necessary to pre-establish the correspondence between identification information and display methods for each user, and the number of potential elevator users is usually very large, the amount of identification information and display methods that need to be stored in the database will also be very large. In Method 2 of this embodiment, the presentation method is no longer related to the user, but corresponds to the guidance sign. The guidance sign is determined by all possible combinations of the call signal registration device and the elevator. Therefore, the number of possible guidance signs is fixed and is usually much smaller than the number of possible elevator users, which obviously overcomes the drawbacks of Reference 1.

[0139] To facilitate the identification of directional signs by multiple passengers simultaneously in the elevator waiting area, different presentation methods are typically used. To ensure that the presentation methods for directional signs corresponding to multiple passengers in the waiting area are not duplicated, the presentation methods are usually pre-established and stored in the presentation method storage unit, making each presentation method different. Thus, the presentation method selection unit will inevitably select different presentation methods for different directional signs from the presentation method storage unit, thereby ensuring that the presentation methods for directional signs corresponding to multiple passengers in the waiting area are not duplicated.

[0140] As can be seen from paragraph

[0037] of document 1, when the guidance display unit 43 has established a corresponding display mode with two or more identified users, it displays the path guidance signs to at least a portion of the users in a display mode different from the repeated display mode. However, this processing method has problems in the following scenarios:

[0141] At time k1, passenger A registers an elevator call signal through elevator call signal registration device A (such as a turnstile). The elevator group control system assigns elevator A as its responding elevator, and the guidance sign system provides guidance sign A to passenger A in presentation mode A. After time Δt, when the current time becomes time k2, passenger A enters the elevator lobby and is moving towards its responding elevator A but has not yet reached it. Passenger B also registers an elevator call signal through elevator call signal registration device A (such as a turnstile), and the elevator group control system also assigns elevator B as passenger B's responding elevator. Thus, the guidance sign images for passenger A and passenger B are the same (i.e., both are guidance sign A), but because the corresponding passengers are different, the guidance sign system displays guidance sign A for passenger B in presentation mode B. It's easy to imagine that at time k1, the wayfinding system provides passenger A with wayfinding sign A in presentation mode A. Passenger A will then move towards the responding elevator A along the wayfinding sign displayed in presentation mode A. At time k2, the wayfinding system provides passenger B with wayfinding sign A in presentation mode B. Since the wayfinding signs displayed at times k1 and k2 are the same, the wayfinding sign A displayed in presentation mode B at time k2 will cover the wayfinding sign A displayed in presentation mode A that started at time k1 and continued until time k2. For passenger A, the sudden change in the display of the wayfinding signs in front of them while moving towards the responding elevator A will inevitably cause confusion and unease.

[0142] In embodiments B and C, since their presentation does not correspond to passengers (i.e., elevator users) but rather to guidance signs (or a combination of a call signal registration device and an elevator), in the aforementioned scenario, when the guidance sign system provides guidance services to passengers A and B, the call signal registration device and the responding elevator corresponding to both passengers are the same, therefore the guidance signs are also the same, and consequently, the presentation methods are the same. Thus, for passenger A who enters the waiting hall first, the guidance sign in front of him (actually, the part of the guidance sign in front of passenger A) remains inconvenient before and after time k2, thus avoiding confusion and unease for passenger A. This also highlights the creativity and outstanding technical effect of embodiments B and C compared to document 1.

[0143] Example 6

[0144] In embodiment 5, the presentation mode selection unit in the control module obtains the selected presentation mode from the presentation mode storage unit.

[0145] In this embodiment, the presentation mode is determined by the presentation mode determination unit based on the presentation mode of the currently presenting guide icon, and its structure is as follows: Figure 5As shown.

[0146] After determining the presentation mode each time, the presentation mode determination unit saves the presentation mode until the presentation termination determination unit determines to terminate the presentation of the guide icon that uses the presentation mode. In this way, when the presentation mode determination unit determines the presentation mode for a new guide icon from the generation module each time, it can predetermine the presentation mode already used by the guide icon that is currently in the presentation state.

[0147] The presentation method determination unit determines the presentation method of the next new guide icon to be presented using any of the following methods:

[0148] Method A: Determine whether there is an intersection between the new guide sign and the currently displayed guide sign; if there is, present the new guide sign in a different way than the guide sign with the intersection; the difference here means that it can reflect the coverage relationship between the two guide signs (as in Example 3).

[0149] Method B: Determine the presentation method of the new guide sign, so that the presentation method of the new guide sign is different from the presentation method of the guide sign that is currently in the presentation state;

[0150] Method C: Determine the presentation mode of the new guide sign so that the presentation mode of the new guide sign is different from the presentation mode of the currently present guide sign adjacent to it.

[0151] Example 7

[0152] In Example 6, the presentation mode storage unit actually associates and stores the guide identifier (or device information and elevator information, or the marker of the guide identifier) ​​with the corresponding presentation mode. In this example, the control module also includes a presentation mode storage unit and a presentation mode selection unit; the presentation mode storage unit is used to store pre-established presentation modes, but does not store the correspondence between the presentation mode and the guide identifier. That is, although the presentation mode of the guide identifier is also pre-established in this example, there is no correspondence between the presentation mode and the guide identifier.

[0153] The presentation mode selection unit selects a presentation mode from the presentation mode storage unit based on the information obtained by the acquisition module. If the presentation termination module does not output a presentation termination command, the control unit controls the identification presentation device to generate a guide identifier according to the presentation generation module of the selected presentation mode.

[0154] The method by which the presentation mode selection unit selects a presentation mode is as follows:

[0155] When there are no other passengers waiting in the elevator lobby, any one of the presentation methods can be selected as the preferred presentation method.

[0156] When there are other passengers waiting for the elevator in the waiting hall, if the other passenger's call signal registration device and responding elevator are exactly the same as the current passenger's, the other passenger's presentation mode is used as the current passenger's selected presentation mode. Otherwise, if the other passenger is moving toward its responding elevator and its responding elevator has not yet arrived at its floor, its guidance sign presentation mode is listed as an unselectable presentation mode. From the pre-established presentation modes, one of the remaining presentation modes other than those listed as unselectable presentation modes is selected as the selected presentation mode.

11. The elevator guidance signage system according to claim 3, characterized in that, The sign generation unit uses the current guide sign as a preset guide sign, and then selects the sign start point and / or sign end point in real time within the preset guide sign. Based on the sign start point and sign end point, it generates the final guide sign. The guide sign uses the sign start point and sign end point as endpoints, pointing from the sign start point to the sign end point. The sign start point and sign end point are both points on the preset guide sign. The sign start point is located behind the area that the passenger has already passed, and the sign end point is located in front of the area that the passenger has not yet passed. The distance between the sign start point and sign end point and the passenger's real-time position is less than a preset threshold.

12. The elevator guidance signage system according to claim 3, characterized in that, When the sign generation unit detects that at least two guide signs have an intersection, it makes the shape of one of the guide signs at the intersection different from the shape at the non-intersection point, thereby reflecting the overlapping relationship between the different guide signs.

Method 2: Determine the coverage relationship between the guidance signs based on the relative position and distance between the passenger's location and the intersection. When a passenger has already passed the intersection, the guidance sign corresponding to the passenger who has already passed the intersection will be the one being covered. When no passenger has passed the intersection, the guidance sign corresponding to the passenger who has passed the intersection first will be the one being covered.

14. The elevator guidance signage system according to claim 9 or 10, characterized in that, The method for generating a guidance identifier by the identifier generation unit includes the following steps: Step T1: Connect the starting point and the ending point of the marker to obtain a straight line segment; Step T2: Determine the direction of the boundary line of the waiting hall; Step T3: Determine whether the line segment is parallel to one of the two directions. If so, use the line segment as a guide marker and end the process; otherwise, proceed to the next step. Step T4: Take one of the starting point and ending point of the guide sign as the first point, and take the other of the starting point and ending point of the guide sign as the second point; Step T5: Draw the first parallel line of the first direction among the two directions through the first point; Step T6: Draw a perpendicular line from the second point to the parallel line to obtain the foot of the perpendicular; Step T7: Select any point between the first point and the perpendicular foot as the new first point; determine whether the first point satisfies condition one. If it does, proceed to step T8. If it does not, move the first point a preset distance in the direction closer to the first point and use that point as the new first point. Continue until the new first point satisfies condition one and then proceed to step T8. If the condition one still cannot be satisfied after a preset number of checks, proceed to step T8 as well. Condition one is: draw a line parallel to the perpendicular line in step T6 through the first point. The part between the boundary of the elevator side of the elevator hall and the first parallel line has no intersection with other guide signs. Step T8: Draw two parallel lines through the first point, each with a direction different from the first direction. Step T9: Determine whether the second point is located inside the parallel line. If so, combine the line segments between the first and second points in sequence, and use the combination result as a guide marker to end. Otherwise, replace the first direction with two directions that are different from the first direction, and return to step T5.
