Description

Technical Field

[0001] This invention relates to the field of elevators, and more specifically to a method for displaying elevator information. Background Technology

[0002] With technological advancements, elevators can now provide increasingly rich information to passengers and other relevant personnel. This includes elevator operation information such as floor and direction of travel, group control dispatch results based on floor calls, images of passengers waiting in the elevator car, suggestions for changing travel times during peak hours, elevator usage statistics and next maintenance schedules, and fault information in case of elevator malfunctions or breakdowns. Furthermore, elevators may also provide public service announcements on elevator safety, weather information, and breaking news. This information is typically presented to relevant personnel through information displays located inside the elevator car and on the floors.

[0003] To fully utilize the information display devices, as much information as possible is typically displayed to passengers simultaneously within the display resource range of these devices. When the elevator is operating normally, the information display devices inside the car usually display the current floor and direction of travel, according to national standards. When resources are still available, they may also display elevator operation statistics, maintenance information, current time, weather information, and breaking news. In other words, the display resources of the information display devices are fully utilized when the elevator is operating normally.

[0004] When an elevator malfunctions or experiences an abnormality, it needs to display information such as fault information, safety precautions, and reassurance messages to passengers or maintenance personnel. During peak hours, the elevator can also provide passengers with suggestions to board earlier or later to save waiting time, as described in Document 1 with application number CN20181152463.1. When the elevator detects that the car is stuck on a floor due to the door being blocked for an extended period, it needs to provide relevant information about the elevator's delay to waiting passengers on other floors. To display these additional information requirements on the information display device, the information to be displayed becomes a combination of these additional information and the information displayed during normal elevator operation (these two sets are referred to as the information to be displayed). Since the information displayed during normal elevator operation already represents the upper limit of the information display device's display resources, the addition of new information will inevitably lead to insufficient display resources, meaning the information display device's display resources are insufficient to simultaneously display all the information to be displayed. In this case, it is necessary to select from the information to be displayed (the information displayed when the elevator is in normal operation and the newly added information) the information to be displayed, which does not exceed the display resources of the information display device.

[0005] Furthermore, with the development of information display devices, display technologies, and information technology, elevators are able to provide passengers with an increasing amount and variety of information. When there is a large amount and variety of information to be displayed, in addition to considering the display resources of the information display device, other factors that may affect the displayed information also need to be considered, such as whether the content of different information is suitable for simultaneous display.

[0006] Therefore, how to appropriately select the information to display when new information needs to be shown in the elevator becomes a problem that needs to be solved. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide an elevator information display method, which can solve the problem of appropriate processing of the displayed information when the elevator has new information display requirements.

[0008] To solve the above-mentioned technical problems, the present invention provides an elevator information display method, which includes the following steps:

[0009] Step S1: Pre-set at least one event to be monitored. The event to be monitored refers to an event that requires information to be displayed to relevant parties of the elevator through an information display device when it occurs.

[0010] Step S2: Continuously monitor whether at least one event to be monitored has occurred. If the monitoring result is yes, proceed to step S3; otherwise, continue monitoring.

[0011] Step S3: Determine the first information, which refers to the information that the information display device needs to display before the monitored event is detected;

[0012] Step S4: Determine the second information, which refers to the information that needs to be displayed to elevator-related parties because a monitored event has been detected. The second information corresponds to the monitored event.

[0013] Step S5: Obtain the combination of the first information and the second information, and use this combination as the third information;

[0014] Step S6: Select a portion of the third information or all of the third information as the fourth information that the information display device will display after the occurrence time of the monitored event, wherein the fourth information includes a portion or all of the second information.

[0015] Preferably, the event to be monitored includes at least one of elevator events, passenger events, and external events. The elevator event refers to an event in which the elevator experiences an abnormal state that differs from its normal operating state, requiring notification to relevant personnel. The passenger event refers to an event in which a passenger exhibits behavior that differs from the usual behavior expected of a passenger when riding an elevator, either before, during, or after the ride. The external event refers to instructions input by elevator-related parties to the elevator through on-site or remote operation that affect the elevator's operation.

[0016] Preferably, step S4 determines the second information corresponding to the monitored event based on a pre-established event-information table, wherein the event-information table contains records corresponding to each monitored event, and each record records the monitored event and its corresponding second information.

[0017] Preferably, step S4 determines the second information corresponding to the event to be monitored based on at least one of the event to be monitored and its possible impact on elevator stakeholders, the purpose of information display, the location of the information display device, whether the information display device is shared or exclusive, and the elevator stakeholders to whom the information display is directed.

[0018] Preferably, step S2 monitors the event to be monitored according to the following steps:

[0019] Step A1: Determine the conditions under which the event to be monitored occurs;

[0020] Step A2: Determine whether there is at least one necessary condition among the occurrence conditions. If so, select the necessary condition and proceed to step A5; otherwise, proceed to step A3.

[0021] Step A3: Determine whether there is a specific set of conditions among the occurrence conditions. When all conditions in the specific set of conditions are met, the event to be monitored must have occurred. If so, proceed to step A4; otherwise, output a warning that the event to be monitored cannot be monitored and end.

[0022] Step A4: Select all conditions in the specific condition group as the selected conditions;

[0023] Step A5: Determine the quantity of elements involved in the selected conditions and the evaluation index based on the quantity of elements;

[0024] Step A6: Determine the judgment criteria corresponding to the evaluation index for the event to be monitored. When the evaluation index and the judgment criteria meet the preset conditions, it is determined that the event to be monitored has occurred.

[0025] Preferably, in step A5, when there is only one selected condition, the evaluation index is the element quantity; otherwise, the evaluation index is a function with each element quantity as the independent variable.

[0026] Preferably, the fourth information selected in step S6 satisfies the following condition:

[0027] Condition 1: The display resources required for the fourth information do not exceed the display resources that the information display device can provide;

[0028] Condition 2: The fourth information contains the largest number of second information items.

[0029] Preferably, when only one event to be monitored is detected and there is only one piece of second information, if the display resources required by the second information exceed the display resources that the information display device can provide, then the second information is refined according to the display resources that the information display device can provide until it does not exceed the display resources that the information display device can provide; otherwise, the entire second information is incorporated into the fourth information.

[0030] When multiple events to be monitored are detected, resulting in multiple pieces of second information, if the sum of display resources required by all the second information does not exceed the display resources that the information display device can provide, then all the second information will be included in the fourth information; otherwise, the second information to be included in the fourth information will be selected according to the set rules.

[0031] Preferably, the fourth information selected in step S6 also satisfies the following condition:

[0032] Condition 3: All the information to be displayed that makes up the fourth information is suitable for display on the same screen.

[0033] Preferably, step S6 determines whether the information to be displayed is suitable for display on the same screen based on the consistency of the display content, display format, and display style of the information to be displayed.

[0034] Preferably, step S6 selects the fourth information according to the following steps:

[0035] Step B1: Determine whether any two pieces of second information are suitable for display on the same screen. If so, select all the second information and proceed to step B2. Otherwise, select a portion of the second information from the second information according to the set rules, so that the selected second information is suitable for display on the same screen.

[0036] Step B2: Determine whether there is at least one piece of the selected second information that cannot be displayed on the same screen as at least one piece of the first information in the third information. If so, delete the first information that cannot be displayed on the same screen as the second information from the third information and use the combination of the remaining first information and the selected second information as the updated third information. Otherwise, proceed directly to step B3.

[0037] Step B3: Select the final fourth information based on conditions 1 and 2.

[0038] Preferably, the setting rules include at least one of the following: selecting the largest number of second information items, prioritizing the second information items corresponding to high-priority events to be monitored, prioritizing the second information items corresponding to the most recently monitored events to be monitored, and prioritizing the second information items with the highest correlation to the current state of the elevator.

[0039] Compared with the prior art, the beneficial technical effects achieved by the present invention are as follows:

[0040] First, the present invention determines whether there is new information to be displayed by monitoring whether a pre-set event to be monitored occurs. In this way, information is selected only when there is new information to be displayed, making the selection of information more targeted.

[0041] Second, the present invention fully considers the correlation between display resources, the information to be displayed and the current state of the elevator, and whether the content of the information to be displayed is suitable for simultaneous display, and further selects the final display information, thereby ensuring that the information finally determined to be displayed on the information display device is more reasonable. Attached Figure Description

[0042] Figure 1 This is a flowchart of the elevator information display method of the present invention. Detailed Implementation

[0043] The embodiments of the present invention are described below with reference to the accompanying drawings and specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Specific details are set forth in the following description to provide a thorough understanding of the present invention; however, the present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be based on different viewpoints and applications. Those skilled in the art can make various similar extensions and substitutions without departing from the spirit of the present invention.

[0044] Example 1

[0045] The elevator information display method of this invention, as described in this embodiment, is as follows: Figure 1 As shown, the display method includes the following steps:

[0046] Step S1: Pre-set at least one event to be monitored. The event to be monitored refers to an event that, when it occurs, needs to display relevant information to elevator stakeholders (such as passengers, property management, manufacturers, regulatory authorities, and maintenance personnel) through an information display device.

[0047] Step S2: Continuously monitor whether at least one event to be monitored has occurred. If the monitoring result is yes, proceed to step S3; otherwise, continue monitoring.

[0048] Step S3: Determine the first information, which refers to the information that the information display device needs to display before the monitored event is detected;

[0049] Step S4: Determine the second information, which refers to the information that needs to be displayed to elevator-related parties because a monitored event has been detected. The second information corresponds to the monitored event.

[0050] Step S5: Obtain the combination of the first information and the second information, and use this combination as the third information;

[0051] Step S6: Select a portion of the third information or all of the third information as the fourth information that the information display device will display after the occurrence time of the monitored event, wherein the fourth information includes a portion or all of the second information.

[0052] The first piece of information includes at least the current floor where the elevator car is located, or it may also include the direction of travel, elevator operation statistics, elevator maintenance information, current time, current weather news, hot news, and elevator safety information.

[0053] The monitored events include at least one of elevator events, passenger events, and external events. Elevator events refer to events where the elevator experiences an abnormal state different from its normal operating state, requiring notification to relevant personnel. Examples include abnormal / fault states, decreased leveling accuracy, re-leveling during a stop, abnormal shaking, repeated door closing, overcrowding in the car, and entering energy-saving / standby mode. Passenger events refer to events where passengers exhibit behaviors different from those expected of ordinary passengers before, during, or after using the elevator. Examples include running from the waiting area away from the elevator towards the elevator, regular travel patterns, quickly pressing multiple floor buttons simultaneously after entering the car, jumping or fainting inside the car, blocking the door for an extended period, carrying sharp objects or pets, lingering in front of the hall door after leaving the car, missing the next / next elevator, or taking the wrong elevator. The external events refer to instructions input by elevator stakeholders to the elevator through on-site or remote operation that immediately or at a set time affect the elevator's operation. Examples include scheduled maintenance plans and related information, meetings or major events designated by the property management company, information requested by passengers (such as elevator health assessment results), and monitoring instructions input by manufacturers or regulatory authorities through a remote monitoring center.

[0054] Specifically, step S2 monitors the event to be monitored according to the following steps:

[0055] Step A1: Determine the conditions under which the event to be monitored occurs;

[0056] Step A2: Determine whether there is at least one necessary condition among the occurrence conditions. If so, select the necessary condition and proceed to step A5; otherwise, proceed to step A3.

[0057] Step A3: Determine whether there is a specific set of conditions among the occurrence conditions. When all conditions in the specific set of conditions are met, the event to be monitored must have occurred. If so, proceed to step A4; otherwise, output a warning that the event to be monitored cannot be monitored and end.

[0058] Step A4: Select all conditions in the specific condition group as the selected conditions;

[0059] Step A5: Determine the quantity of elements involved in the selected conditions and the evaluation index based on the quantity of elements;

[0060] Step A6: Determine the judgment criteria corresponding to the evaluation index for the event to be monitored. When the evaluation index and the judgment criteria meet the preset conditions, it is determined that the event to be monitored has occurred.

[0061] In step A5, when there is only one selected condition, the evaluation index is the element quantity; otherwise, the evaluation index is a function with each element quantity as the independent variable.

[0062] This embodiment continuously monitors whether the pre-set events to be monitored have occurred in order to determine whether there is any new information that needs to be displayed. This allows information to be selected only when there is new information to be displayed, making the selection of information more targeted and reasonable.

[0063] Example 2

[0064] Based on Example 1, this example further explains how to obtain the display content corresponding to the monitored event after it has been detected.

[0065] Specifically, in step S4, the second information corresponding to the monitored event that has occurred is determined according to the pre-established event-information table. The event-information table contains records corresponding to each monitored event, and each record records the monitored event and its corresponding second information.

[0066] Alternatively, in step S4, the second information corresponding to the monitored event is determined based on at least one of the following: the event to be monitored and its potential impact on elevator stakeholders, the purpose of the information display, the location of the information display device, whether the information display device is shared or exclusive, and the elevator stakeholders to whom the information display is directed. For example, when it is detected that the time until the next maintenance is less than a threshold, a maintenance warning message containing the start time and duration of maintenance can be displayed at the landing and / or in the elevator car; when it is detected that the elevator car is stuck on a floor for an extended period of time due to passengers blocking the light curtain, the abnormal situation is notified to waiting passengers on the floor via the information display device located on the floor with the floor request signal.

[0067] Example 3

[0068] Based on Embodiment 1 and Embodiment 2, this embodiment explains how to select the information to be displayed by the information display device after a monitored event has occurred and been detected.

[0069] First, the fourth information selected in step S6 satisfies the following condition:

[0070] Condition 1: The display resources required for the fourth information do not exceed the display resources that the information display device can provide;

[0071] Condition 2: The fourth information contains the largest number of second information items.

[0072] Here, the display resources of the information display device mainly include several aspects:

[0073] 1) Display area: This mainly refers to the size, shape, etc. of the display area on the screen of the information display device that can be used to display information;

[0074] 2) Display capability: This mainly refers to the display capabilities of an information display device, such as brightness, color, refresh rate, and resolution.

[0075] 3) Processing capability: This mainly refers to the ability to acquire display data and, after appropriate processing, generate display information that can be displayed on an information display device.

[0076] In engineering practice, the display area of ​​an information display device usually limits the information that can be displayed. The following explanation uses the display area as an example to illustrate the selection of the fourth type of information.

[0077] After obtaining the third information, the system will calculate the display area required for each piece of information to be displayed in the third information (in fact, the shape of the display area also needs to be considered to avoid the display area being large enough but the shape not meeting the requirements, such as the remaining available display area being a long and narrow strip, but the information to be displayed requires a roughly square display area, and the smaller side of the long and narrow strip display area is smaller than the side length of the square display area required by the information to be displayed), in order to prepare for the subsequent selection of the information to be displayed in the third information based on display resources.

[0078] When only one event to be monitored is detected and there is only one piece of second information (all information that needs to be displayed when one event to be monitored is considered as one piece of second information), if the display resources required by the second information exceed the display resources that the information display device can provide, then the second information is refined according to the display resources that the information display device can provide until it does not exceed the display resources that the information display device can provide; otherwise, the entirety of the second information is incorporated into the fourth information.

[0079] When multiple events to be monitored are detected, resulting in multiple pieces of second information, if the sum of display resources required by all the second information does not exceed the display resources that the information display device can provide, then all the second information will be included in the fourth information; otherwise, the second information to be included in the fourth information will be selected according to the set rules.

[0080] The setting rules include at least one of the following: selecting the largest number of second information items, prioritizing the second information items corresponding to high-priority events that have occurred and are to be monitored, prioritizing the second information items corresponding to the most recently monitored events that have occurred and are to be monitored, and prioritizing the second information items that have the highest correlation with the current state of the elevator.

[0081] The priority (or importance) of events to be monitored is primarily determined by considering the impact of the event on passengers and / or the severity of the consequences. For example, when two events—repeated elevator door opening and closing and overcrowding in the elevator car—occur simultaneously, it is clear that the impact of repeated door opening and closing on passengers is greater than that of overcrowding. Therefore, for the displays on the floors where passengers waiting for the elevator are located, the display information corresponding to repeated door opening and closing should have a higher priority than the display information corresponding to overcrowding.

[0082] Regarding the relevance of information to the current elevator status, for example, if it's currently peak travel time and a monitored event (crowded elevator car, many passengers waiting at the landing) is detected, then the display inside the car needs to show the waiting situation in the landing lobby, and the landing display needs to show the passenger congestion in the car. Additionally, it's desirable to simultaneously provide passengers with suggestions such as "changing your travel time can save waiting time." The emergence of this additional display information (i.e., the second set of information including the waiting situation in the landing lobby, the passenger congestion in the car, and the travel suggestions) means that the display resources required for this information far exceed the display capacity of the existing monitors. Therefore, it's necessary to discard some information that is not highly relevant to the current elevator status. If the first information contains news headlines, elevator safety videos, elevator usage status, and the current floor and direction of travel of the elevator car before the second information appears, then clearly, the results of sorting this information from highest to lowest relevance to the current elevator status would be: current floor and direction of travel of the elevator car (which is required to be displayed inside the elevator car according to national standards), waiting situation and passenger congestion, elevator riding suggestions, elevator safety videos, elevator usage status, and news headlines. Based on the relevance ranking, the information can be selected from beginning to end depending on the resources needed for display.

[0083] This embodiment fully considers the display resources available from the information display device and the display resources required for the information to be displayed, and filters the information to be displayed. This ensures that the final selected fourth information does not exceed the display resources of the information display device, and also ensures that the final displayed information is more consistent with the current state of the elevator.

[0084] Example 4

[0085] Based on Embodiment 1 and Embodiment 2, this embodiment explains how to select the information to be displayed by the information display device after a monitored event has occurred and been detected.

[0086] The fourth piece of information selected in step S6 satisfies the following condition:

[0087] Condition 1: The display resources required for the fourth information do not exceed the display resources that the information display device can provide;

[0088] Condition 2: The fourth information contains the most instances of the second information.

[0089] Condition 3: All the information to be displayed that makes up the fourth information is suitable for display on the same screen.

[0090] In step S6, it is determined whether the information to be displayed is suitable for display on the same screen based on the consistency of its content, format, and style. Specifically:

[0091] First, the displayed content must not contradict each other. For example, when an elevator malfunctions and traps passengers, the system typically provides information about the malfunction and reassurance to the trapped passengers. At this time, it's inappropriate to continue displaying information about the elevator's direction of travel before the malfunction occurred (because the elevator was stationary at that point). Furthermore, it's not advisable to simultaneously provide information about the elevator's safety and reliability while displaying malfunction information. Similarly, when the weather is described as heavy rain or low temperatures, it's inappropriate to play content about maintenance personnel braving high temperatures and extreme heat to maintain the elevators.

[0092] Second, the displayed content should be consistent; that is, the content should not be too contrasting or reflect too much difference in theme. For example, when promoting the convenience of elevators for passengers and making elevator rides an enjoyable experience (embodying a relaxed and pleasant feeling), information about elevator safety accidents caused by improper maintenance or elevator use should not be displayed (providing a heavy, sad, and sobering experience).

[0093] Third, the display format and style should be kept as consistent as possible. For example, cartoon-style, brightly colored safety elevator promotional materials should not be displayed simultaneously with serious warning signs or statistical charts (at least they should not be placed next to each other), and the styles should be as similar as possible.

[0094] Specifically, step S6 selects the fourth information according to the following steps:

[0095] Step B1: Determine whether any two pieces of second information are suitable for display on the same screen. If so, select all the second information and proceed to step B2. Otherwise, select a portion of the second information from the second information according to the set rules, so that the selected second information is suitable for display on the same screen.

[0096] Step B2: Determine whether there is at least one piece of the selected second information that cannot be displayed on the same screen as at least one piece of the first information in the third information. If so, delete the first information that cannot be displayed on the same screen as the second information from the third information and use the combination of the remaining first information and the selected second information as the updated third information. Otherwise, proceed directly to step B3.

[0097] Step B3: Based on conditions 1 and 2, select the final fourth information from the second information.

[0098] The setting rules include at least one of the following: selecting the largest number of second information items, prioritizing the second information items corresponding to high-priority events that have occurred and are to be monitored, prioritizing the second information items corresponding to the most recently monitored events that have occurred and are to be monitored, and prioritizing the second information items that have the highest correlation with the current state of the elevator.

[0099] This embodiment fully considers the suitability of display resources and display content to be displayed simultaneously, and filters the information to be displayed. This ensures that the final selected fourth information does not exceed the display resources of the information display device, and also ensures that the content of the final displayed information is more reasonable and in line with public perception.

[0100] The present invention has been described in detail above through specific embodiments. These embodiments are merely preferred embodiments of the present invention, and the present invention is not limited to the above-described implementation methods. Any equivalent substitutions and improvements made by those skilled in the art to the types of risk assessment data, rules for identifying adverse risks, etc., without departing from the principles of the present invention, should be considered within the scope of the technology protected by the present invention.
