Description

Technical Field

[0001] This invention relates to elevator technology, and in particular to an elevator ride suggestion system and method. Background Technology

[0002] When passenger elevator usage fluctuates, there are often times when elevators are crowded and passengers wait in the lobby for a long time. At other times, when there are fewer passengers, the elevator ride is more comfortable (compared to the crowds during peak hours), the ride is shorter, and the elevator may even be relatively idle.

[0003] To address this issue, the technical solution disclosed in Document 1 (Japanese Patent JP2016160079) analyzes past elevator usage data to identify and provide passengers with information on peak hours, enabling them to understand and avoid these times. This solution involves uniformly informing all passengers to encourage them to avoid congestion.

[0004] Considering that elevator congestion doesn't occur on all floors, but rather on specific floors (departure and / or destination floors), the approach in Reference 1, which uniformly informs all passengers, is not entirely reasonable. Ideally, relevant information should only be sent to specific, relevant passengers, encouraging them to adjust their travel times to avoid congestion.

[0005] To address this, Reference 2 (Chinese Invention Patent Application CN201811524634.1) proposes using elevator usage history data to determine if the number of elevator users exceeds a threshold. If it does, when congestion is detected at a specific departure / destination floor, notification information is sent only to passengers on that floor, along with a suggested change of elevator usage time. Reference 2 determines congestion based on the number of elevator users and sends notification information only to passengers on the affected departure / destination floors. When congestion occurs, it recommends a slightly off-time for specific elevator users on the affected departure and destination floors, allowing them to use the elevator at that recommended time. This avoids peak congestion times to some extent, overcoming the drawback of Reference 1, which sends notification information to all elevator users.

[0006] However, Reference 2 simply identifies the floors experiencing congestion and recommends changes to elevator usage times for passengers on those floors, placing its hopes for alleviating congestion on these users changing their elevator usage times. This merely smooths out peak congestion without analyzing the underlying causes of congestion (in many cases, passengers on the departure / destination floors experiencing congestion are not the root cause of the congestion). Furthermore, it does not consider the overall operating efficiency of the elevator when selecting recommended elevator times and specific users. Its selection of recommended elevator times and specific users does not help improve overall operating efficiency and may even further reduce it in some cases.

[0007] For example, during the morning rush hour when passenger flow is relatively high, there are 8 passengers going from the 1st floor to the 10th floor, 7 passengers going to the 15th floor, 1 (3) passengers going from the B1 floor to the 8th floor, and 2 passengers going from the B2 floor to the 12th floor. Through analysis, it can be found that the 3 passengers going from the B1 floor to the 8th floor and from the B2 floor to the 12th floor caused the elevator to stop 4 times but only transported 3 passengers, which seriously affected the passenger transport efficiency of the elevator from the perspective of transport efficiency. According to the scheme in Reference 2, the congestion usually occurs on the 1st floor. At this time, informing elevator users going from the 1st floor to the 10th and 15th floors to change their elevator travel time is obviously less effective in improving the elevator's passenger transport efficiency than informing passengers taking the elevator from the B1 and B2 floors to change their elevator travel time. The reason for this problem is that Reference 2 simply decides to inform elevator users who need information based on the appearance of congestion, without analyzing the deeper reasons for the congestion.

[0008] For example, during the morning rush hour when passenger flow is relatively high, there are 8 passengers going from the 1st floor to the 10th floor, 7 passengers going to the 15th floor, 3 passengers going from the 3rd floor to the 8th floor, and 1 passenger going from the 3rd floor to the 12th floor. If the elevator detects congestion when it goes up to the 3rd floor, according to the scheme in Reference 2, the elevator users whose departure floor is the 3rd floor are advised to delay their trip by 5 minutes. If 2 elevator users who depart from the 3rd floor to the 8th floor and 1 elevator user who departs from the 3rd floor to the 12th floor follow the advice and delay their trip, The results show that the elevator car stops remain unchanged, which does not affect the elevator's operating efficiency (and may even decrease it due to the reduced number of passengers). In fact, if there are no passengers departing from the 3rd floor and / or arriving at the 8th and 12th floors 5 minutes later, the elevator's operating efficiency will be further reduced, resulting in longer actual elevator ride times for passengers. In other words, although the elevator may not be as crowded as it used to be, the elevator ride time may be longer and the elevator's operating efficiency may decrease, leading to an increase in the overall energy consumption of the elevator. Summary of the Invention

[0009] The technical problem to be solved by this invention is to reduce the number of stops of the elevator car and improve the operating efficiency of the elevator.

[0010] To solve the above-mentioned technical problems, the present invention provides an elevator ride suggestion system, which includes:

[0011] The congestion storage module is used to associate and store the causes of elevator congestion, the corresponding congestion mitigation measures, and their applicable conditions.

[0012] The information acquisition module is used to acquire congestion-related information from elevator operation information. The information categories of the congestion-related information are pre-specified according to the cause of congestion, the congestion mitigation measures, and the applicable conditions.

[0013] The congestion monitoring module is used to monitor whether the elevator is crowded based on the congestion-related information obtained by the information acquisition module.

[0014] The determination module determines, when the congestion monitoring module detects elevator congestion, the implementable congestion mitigation measures that can alleviate the current elevator congestion based on the congestion-related information and the stored content in the congestion storage module, and outputs them as implementable congestion mitigation measures.

[0015] The suggestion content generation module generates elevator riding suggestions that include the implementable congestion mitigation measures based on the implementable congestion mitigation measures.

[0016] The notification module is used to inform elevator users of the elevator riding suggestions generated by the suggestion generation module.

[0017] Preferably, the determining module further includes:

[0018] The cause analysis unit analyzes the causes of elevator congestion based on the elevator operation information.

[0019] The means determination unit is used to determine the available congestion relief means based on the congestion cause output by the cause analysis unit and the congestion cause and its corresponding congestion relief means in the congestion storage module, and output them as available congestion relief means.

[0020] The judgment unit is used to determine whether the optional congestion relief method output by the means determination unit is feasible based on the congestion-related information and the applicable conditions corresponding to the congestion relief methods in the congestion storage module. When the congestion-related information meets the applicable conditions, it is determined that there is an feasible optional congestion relief method, and the optional congestion relief method output by the means determination unit is output as an feasible congestion relief method.

[0021] Preferably, the suggestion condition generation module is further configured to generate suggestion notification conditions corresponding to the elevator riding suggestion content based on the implementable congestion mitigation measures, wherein the suggestion notification conditions include at least one of the notification recipient, notification time, and notification location of the elevator riding suggestion;

[0022] The notification module outputs the elevator riding suggestion content according to the suggested notification conditions, thereby informing the elevator users of the elevator riding suggestion content.

[0023] Preferably, the elevator ride suggestion system further includes a threshold storage module;

[0024] The threshold storage module stores at least one of the following: passenger capacity threshold, area threshold, weight threshold, passenger capacity threshold, waiting time threshold, and riding time threshold.

[0025] Preferably, the congestion causes include at least one of the following: large resource occupation, dispersed departure and / or destination floors of elevator users, concentrated large passenger flow, improper use of elevators by users, and unreasonable settings of elevator group management parameters.

[0026] The term "large resource consumption" includes passengers carrying large items or passengers whose journey takes a long time.

[0027] The elevator group management parameter settings include the division of service floors and the setting of peak hours.

[0028] Preferably, when the congestion monitoring module detects congestion in the elevator, if the elevator image acquisition device captures an image inside the elevator car showing a large item inside the elevator car or the weighing result output by the elevator weighing device is less than a threshold, the cause of congestion output by the cause analysis module is that the elevator user is carrying a large item.

[0029] Preferably, when the congestion monitoring module detects elevator congestion, if the number of elevator users' departure floors and / or destination floors exceeds a threshold within a certain period of time, the cause of congestion output by the cause analysis module is that the elevator users' departure floors and / or destination floors are dispersed.

[0030] Preferably, when the number of elevator users in the waiting hall or the waiting time of elevator users exceeds a threshold within a unit time, or when the weighing result output by the elevator weighing device within a unit time shows that the number of times the elevator is overloaded exceeds a threshold, the cause of congestion output by the cause analysis module is a concentrated large passenger flow.

[0031] The waiting time of the elevator users is the average waiting time of all elevator users, or the longest waiting time among all elevator users.

[0032] Preferably, the elevator operation information also includes operation information reflecting the operation of the elevator by the user.

[0033] When the operation information indicates that the elevator user has performed improper operation on the elevator, the cause analysis module outputs the cause of congestion as improper use of the elevator by the user.

[0034] Preferably, when the elevator operation information of a certain elevator dispatching function of the elevator group management system, which is affected by relevant parameters of the elevator group management system, indicates that the actual effect of the elevator dispatching function is lower than the expected effect, the cause of congestion output by the cause analysis unit is that the elevator group management parameters are set unreasonably.

[0035] Preferably, the elevator dispatching function affected by the relevant parameters of the elevator group management system is an elevator zone service, the corresponding elevator operation information is the congestion level in different zones, and the corresponding elevator group management parameter is the service area division parameter.

[0036] When the actual passenger flow difference of elevators serving different service areas exceeds a threshold, the cause of congestion output by the cause analysis module is that the service area division parameter setting is unreasonable.

[0037] Preferably, the elevator dispatching function affected by the relevant parameters of the elevator group management system is for handling peak passenger flow periods, and the corresponding elevator operation information is the elevator user's call signal and the time of its generation, and the corresponding elevator group management parameter is the peak passenger flow period.

[0038] When the actual passenger flow corresponding to the current peak passenger flow period is less than the actual passenger flow during off-peak periods, the cause of congestion output by the cause analysis module is that the peak period parameter settings are unreasonable.

[0039] Preferably, the congestion-related information includes passenger flow on each floor when the elevator is congested;

[0040] The cause of congestion is that elevator users are scattered on the departure floor and / or destination floor. The congestion relief measure corresponding to this cause is to take the elevator to the nearest floor with high passenger flow. The applicable conditions are that there are floors with high passenger flow and floors with low passenger flow. The notification location in the suggested notification conditions is the floor with low passenger flow.

[0041] When the cause of congestion is that the departure floor and / or destination floor of the elevator users are dispersed, if the means determination unit determines that the optional congestion relief means is to take the elevator to the nearest floor with high passenger flow, and determines that there are floors with high passenger flow and floors with low passenger flow based on congestion-related information, then the means determination unit outputs taking the elevator to the nearest floor with high passenger flow as an implementable congestion relief means.

[0042] The notification module will inform elevator users on the low-passenger-flow floors that if the distance between the low-passenger-flow floor and the nearest high-passenger-flow floor is less than a set number of floors, the elevator will suggest taking the elevator to the nearest high-passenger-flow floor.

[0043] Preferably, after receiving the elevator usage suggestion, the notification module will inform elevator users on the low-traffic floors that if the number of floors between the low-traffic floors and the nearest high-traffic floors is not less than a set number, the module will suggest postponing or advancing the elevator usage to a less congested time period.

[0044] Preferably, after receiving the elevator ride suggestion, the notification module outputs video or audio to the nearest high-traffic floor from the low-traffic floor as a suggestion to ride the elevator.

[0045] Preferably, the judgment unit determines the passenger flow of each floor based on the number of passengers entering and leaving the elevator car on each floor. If the number of passengers entering and leaving the elevator car on a floor for N consecutive stops is greater than a set upper limit, where N is a positive integer, then that floor is a high-passenger-flow floor. If the number of passengers entering and leaving the elevator car on a floor for N consecutive stops is less than a set lower limit, and the set lower limit is less than half of the set upper limit, then that floor is a low-passenger-flow floor.

[0046] Preferably, the maximum number of passengers is set to be greater than 1.5 times the rated passenger capacity of the car.

[0047] Preferably, the notification module outputs video or audio suggestions to the nearest high-traffic floor for taking the elevator, including walking to the nearest high-traffic floor and also including improved elevator operating efficiency and reduced passenger elevator travel time.

[0048] Preferably, if the number of passengers in the waiting area of ​​an elevator on the first floor exceeds a threshold for a set time, the congestion monitoring module determines that the elevator is congested and records the congested floor and the congestion time in the congestion database.

[0049] If the current congested floor and congestion time are regular congested floors and congestion times in the congestion database, the judgment unit determines whether there are currently high-passenger-flow floors and low-passenger-flow floors based on the passenger flow on each floor when the elevator is congested. Otherwise, it is uncertain whether there are currently high-passenger-flow floors and low-passenger-flow floors. Regular congested floors and congestion times are defined as follows: in the most recent M congestion records in the congestion database, the number of congestion records for that floor at that time exceeds a set proportion, where M is greater than the number of elevator stops F.

[0050] Preferably, the set ratio is 1 / F.

[0051] Preferably, after determining that there are currently high-passenger-flow floors and low-passenger-flow floors, the judgment unit outputs the information of high-passenger-flow floors and low-passenger-flow floors to the notification module, and outputs the time when the elevator is not crowded or the time when the elevator is crowded to the notification module within the previous or next time period of the current time each day.

[0052] The notification module, upon receiving information about floors with high and low passenger flow, outputs elevator usage suggestions via video or audio. If the distance between a floor with low passenger flow and the nearest floor with high passenger flow is less than a set floor value, it outputs a video or audio suggestion to take the elevator to that nearest floor with high passenger flow. Upon receiving information about floors with low passenger flow during off-peak or peak elevator times, it outputs a video or audio suggestion to take the elevator during off-peak or peak elevator times.

[0053] Preferably, the cause of congestion is large resource occupation, and the congestion relief measure corresponding to this cause is to postpone or advance the elevator ride during non-congested hours, and the applicable condition is that there are non-congested hours; the notification recipients in the suggested notification conditions are passengers with large resource occupation.

[0054] When the cause of congestion is large resource occupation, if the means determination unit determines that the optional congestion relief means is to take the elevator to the nearest floor with high passenger flow, the judgment unit will output that postponing or advancing to take the elevator during non-congestion hours is an implementable congestion relief means.

[0055] The notification module informs passengers with high resource usage of suggestions to postpone or advance their elevator ride to a less crowded time.

[0056] To solve the above-mentioned technical problems, the present invention provides an elevator riding suggestion method, which includes the following steps:

[0057] Step S1: Obtain elevator operation information;

[0058] Step S2: Determine whether the elevator is currently crowded based on the elevator operation information. If so, proceed to the next step; otherwise, return to step S1.

[0059] Step S3: Analyze the elevator operation information to determine the cause of the congestion.

[0060] Step S4: Based on the cause of congestion, determine the congestion relief measures and their applicable conditions corresponding to the cause of congestion using the pre-established correspondence between the cause of congestion, congestion relief measures, and applicable conditions.

[0061] Step S5: Determine whether there is at least one implementable congestion relief measure based on the elevator operation information. The implementable congestion relief measure refers to a congestion relief measure that corresponds to the cause of congestion and whose applicable conditions are met.

[0062] Step S6: Generate elevator riding suggestions based on the implementable congestion mitigation measures;

[0063] Step S7: Output the elevator riding suggestion to the elevator user;

[0064] Step S8: Continuously monitor the current elevator congestion until the current congestion ends;

[0065] Step S9: Return to step S1.

[0066] Preferably, the step between step S2 and step S3 further includes:

[0067] Step A1: Based on the current time and the historical data table of congestion duration used to save past elevator congestion periods, determine whether the current elevator congestion is occasional or regular. If it is occasional, proceed to step S8; otherwise, proceed to step S3.

[0068] Preferably, the step between step S8 and step S9 further includes:

[0069] Step B1: Determine the duration of elevator congestion based on the first time the elevator congestion is detected and the end time of the current elevator congestion, and add the new duration of congestion to the historical data table of congestion duration.

[0070] Preferably, when the current time falls within a congestion duration period between 0:00 and 24:00 in the congestion duration period historical data table, and the congestion duration period appears at least m times in the n records closest to the current time in the congestion duration period historical data table, step A1 determines the current elevator congestion as regular; otherwise, it determines it as occasional. A record refers to a congestion duration period stored in the congestion duration period historical data table that represents a certain elevator congestion, where n is a positive integer, m is a positive integer less than or equal to n, and m ≥ n / 10.

[0071] Preferably, step S2 determines a congestion index to characterize the elevator congestion status based on the elevator operation information, and determines whether the elevator is currently congested based on the relationship between the congestion index and the corresponding threshold.

[0072] Preferably, the congestion index is the actual occupied resources when elevator users ride the elevator, and the threshold is the available resources that the elevator can provide to elevator users; or the congestion index is the ratio of the actual occupied resources when elevator users ride the elevator to the available resources that the elevator can provide to elevator users, or the congestion index is the difference between the available resources and the occupied resources, or the ratio of the available resources to the available resources, and the threshold is a given parameter.

[0073] Preferably, the occupied resources are the number of elevator users in the elevator car, and the available resources are the rated passenger capacity of the elevator; or the occupied resources are the actual occupied area of ​​elevator users in the elevator car, and the available resources are the car floor area available for use by elevator users; or the occupied resources are the weighing results output by the elevator weighing device, and the available resources are the rated load of the elevator; or the occupied resources are the actual number of elevator users waiting to board the elevator, and the available resources are a reasonable upper limit for the number of elevator users waiting to board the elevator; or the occupied resources are the actual waiting time or actual riding time of elevator users, and the available resources are a reasonable upper limit for the waiting time or riding time of elevator users.

[0074] Corresponding to the occupied resources, the elevator operation information includes at least one of the following: the number of elevator users in the elevator car, the area occupied by elevator users in the elevator car, the weighing results output by the elevator weighing device, the number of elevator users in the waiting hall, the waiting time of elevator users, and the actual riding time of elevator users.

[0075] Preferably, step S3 further includes the following sub-steps:

[0076] Sub-step S1: Select an unselected congestion cause from all possible congestion causes and use it as the selected congestion cause;

[0077] Sub-step S2: Determine the congestion cause index corresponding to the selected congestion cause;

[0078] Sub-step S3: Determine the basic information corresponding to the congestion cause index;

[0079] Sub-step S4: Obtain the basic information from the elevator operation information and calculate the congestion cause index;

[0080] Sub-step S5: Compare the calculated congestion cause index with its corresponding threshold.

[0081] Sub-step S6: Determine whether the selected congestion cause is the actual congestion cause based on the comparison result. If yes, proceed to sub-step S7; otherwise, return to sub-step S1.

[0082] Sub-step S7: Output the actual cause of congestion.

[0083] Preferably, sub-step S1 uses historical congestion data to count the number of elevator congestion occurrences caused by each congestion cause, and prioritizes selecting the congestion cause that occurs most frequently.

[0084] Preferably, the step between sub-step S6 and sub-step S7 further includes:

[0085] Sub-step H1: Determine if there are any unselected causes of congestion among all possible causes of congestion. If so, return to sub-step S1; otherwise, proceed to sub-step S7.

[0086] Preferably, in sub-step S7,

[0087] First, analyze the basic information required to calculate the congestion cause index, and determine whether the basic information is incorrect due to device abnormality or malfunction. When determining device abnormality or malfunction, determine the actual congestion cause as the relevant device abnormality or malfunction, and then output the actual congestion cause.

[0088] Preferably, the congestion cause index is a mathematical expression that satisfies the following conditions:

[0089] Condition 1: The specific value can be calculated from the basic information in the elevator operation information;

[0090] Condition 2 corresponds one-to-one with the causes of congestion mentioned above;

[0091] Condition 3: There is a monotonically increasing relationship between the specific numerical value obtained through calculation and the probability that the elevator congestion is the cause of the congestion;

[0092] Condition 4: When its size exceeds the corresponding threshold, it can be determined that the congestion is caused by this congestion.

[0093] Preferably, the congestion is caused by the dispersion of floor calls and / or destination floors. The congestion cause index is the ratio of the total number of passengers transported to the total number of stops between the start and end points of the elevator car in a certain direction of operation, or the ratio of the total distance between the start and end points of the elevator car in a certain direction of operation to the total number of stops. The basic information included in the elevator operation information is the floor calls and destination floors, as well as the corresponding number of elevator users entering / leaving the car.

[0094] Preferably, the congestion is caused by the presence of special elevator users;

[0095] The congestion cause index is the average car floor area occupancy and / or average mass of elevator users in the elevator car. The basic information included in the elevator operation information is the number of elevator users when they take the elevator, as well as the elevator car floor area occupancy information and / or the actual load information of the elevator car; or, the congestion cause index is the car floor area occupancy or mass of the elevator user with the largest car floor area occupancy or mass among all elevator users, and the basic information included in the elevator operation information is the elevator user and their car floor area occupancy information or their mass; or, the congestion cause index is the number of elevator users whose car floor area occupancy or mass exceeds a threshold, and the elevator operation information includes the elevator user and their car floor area occupancy information or their mass; or the congestion is caused by insufficient elevator design capacity; the congestion cause index is the ratio of the elevator design capacity to the actual elevator capacity demand, or the ratio of the difference between the actual elevator capacity demand and the elevator design capacity to the actual elevator capacity demand; the elevator operation information includes elevator user information that needs to take the elevator, and the actual elevator capacity demand is obtained after appropriate processing of the elevator user information that needs to take the elevator.

[0096] Preferably, when there are multiple elevators and an elevator group management system is configured, the cause of congestion is that the parameters of the group management system are set unreasonably. The congestion cause index is the maximum load rate difference between the load rates of each elevator when it departs from the congested floor in the same direction of operation. The elevator operation information includes elevator load rate information.

[0097] Preferably, step S5 determines the implementation of congestion mitigation measures according to the following steps:

[0098] Step D1: Select an unselected congestion relief method from all congestion relief methods corresponding to the cause of congestion, and use the selected congestion relief method as the chosen congestion relief method;

[0099] Step D2: Determine the basic information required to determine whether the selected congestion relief measure is valid based on the applicable conditions corresponding to the selected congestion relief measure;

[0100] Step D3: Use the basic information contained in the elevator operation information to determine whether the applicable conditions corresponding to the selected congestion relief method are met. If they are met, the selected congestion relief method is used as the congestion relief method and output, and the process ends; otherwise, proceed to step D4.

[0101] Step D4: Determine if there are still unselected congestion relief measures. If so, return to step D1; otherwise, output a notification message that no such congestion relief measure exists and end the process.

[0102] Preferably, step D1, when making the selection, further includes the following sub-steps:

[0103] Sub-step D1-1: Based on the congestion cause, determine each congestion relief measure corresponding to the congestion cause using the congestion cause-congestion relief measure-applicable condition correspondence relationship;

[0104] Sub-step D1-2: Search and count the number of times each congestion mitigation measure was implemented as an implementable congestion mitigation measure when congestion occurred due to this congestion cause in the historical data.

[0105] Sub-steps D1-3: Select the congestion relief method with the highest number of implementations from all unselected congestion relief methods as the selected congestion relief method.

[0106] Preferably, the congestion is caused by the dispersion of elevator users' departure and / or destination floors; congestion mitigation measures corresponding to this cause include:

[0107] 1) The applicable conditions for elevator users to walk to the nearest high-traffic floor to take the elevator are: a) there are high-traffic floors and low-traffic floors among the elevator user's departure floor and / or destination floor; b) the distance between one of the high-traffic floors and / or low-traffic floors and the other of the nearest high-traffic floors and / or low-traffic floors does not exceed a threshold, or there are other conditions; c) the travel distance corresponding to a single elevator stop is less than a threshold. Step D3 analyzes and determines whether the above applicable conditions are met based on the elevator user registration information in the elevator operation information and / or the weighing results of the weighing device used to detect the load in the elevator car when the elevator starts at each floor.

[0108] 2) The applicable conditions for elevator users to change their elevator ride time are: a) the current elevator congestion is a regular phenomenon, b) the time interval between the current time and the start or end time of the historical congestion period corresponding to the current congestion is less than a threshold, or the condition c) there are elevator users who frequently ride the elevator at this time; step D3 analyzes and determines whether the above applicable conditions are met based on the current time contained in the elevator operation information.

[0109] Preferably, when the applicable conditions of the above two congestion relief methods are met simultaneously, step D3 selects the congestion relief method according to the attributes of the elevator users.

[0110] Preferably, step D3 directly determines the elevator user's attributes based on the elevator operation information (such as based on the IC card carried by the passenger, video images, etc.), or infers the elevator user's attributes based on the attributes of the building where the elevator is located and / or the current time. The attributes refer to whether the elevator user is suitable for walking or whether they are time-sensitive.

[0111] Preferably, the passenger flow on each floor is determined based on the number of elevator users entering and leaving the elevator car on each floor. If the number of elevator users entering and / or leaving the elevator car during N consecutive stops at a certain floor is greater than a set upper limit value, where N is a positive integer, then that floor is identified as a high-passenger-flow floor. If the number of elevator users entering and leaving the elevator car during N consecutive stops at a certain floor is less than a set lower limit value, then that floor is identified as a low-passenger-flow floor.

[0112] Preferably, the elevator operation information includes the number of elevator users waiting to ride the elevator on each floor and their waiting time. When the number of elevator users waiting to ride the elevator on a certain floor exceeds a threshold, or when the number of elevator users waiting to ride the elevator on a certain floor exceeds the quantity threshold and the duration of this phenomenon exceeds the time threshold, that floor is identified as a high-traffic floor. Conversely, when the number of elevator users waiting to ride the elevator on a certain floor is less than the threshold, or when the number of elevator users waiting to ride the elevator on a certain floor is less than the quantity threshold and the duration of this phenomenon is less than the time threshold, that floor is identified as a low-traffic floor.

[0113] Ideally, in addition to defining floors with high passenger flow and floors with low passenger flow, a regularity constraint based on historical data should be added.

[0114] Preferably, the cause of congestion is high resource consumption, and the corresponding congestion mitigation measures are:

[0115] 1) It is recommended that elevator users change their elevator usage time. The applicable conditions are: a) There is a non-crowded period; b) The time interval between the current time and the non-crowded period is less than the time threshold. Step D3 analyzes the elevator's historical data and determines whether the above applicable conditions are met.

[0116] 2) It is recommended that elevator users change their elevator ride times and share elevator rides with other users of high-resource elevators. The applicable conditions are: a) There are non-crowded periods; b) The time interval between the current time and the non-crowded period is less than a time threshold; c) There are other users of high-resource elevators during the non-crowded period. Step D3 also analyzes and confirms whether the applicable conditions are met based on elevator historical data. The elevator historical data display includes information on crowded periods and information on users of high-resource elevators during crowded periods. The information on users of high-resource elevators includes resource occupancy information and elevator ride time distribution information.

[0117] Ideally, based on the above applicable conditions, a regularity requirement is added, with the aim of ensuring that the applicable conditions for the changed elevator time do not apply when elevator users take the elevator for the first time.

[0118] Preferably, the cause of congestion is an unreasonable setting of the group management system parameters. The congestion mitigation measure corresponding to this cause is to report the unreasonable setting of the group management system parameters to the elevator-related parties. The applicable condition is that there is a way to report information to the elevator-related parties. Step D3 determines whether the applicable condition is met based on the stored information feedback channel information.

[0119] Preferably, the cause of congestion is that the elevator's designed capacity is insufficient to meet the actual demand. The congestion mitigation measure corresponding to this cause is to propose an upgrade and renovation plan aimed at improving the elevator's capacity. The applicable condition is that the cause of congestion is that the elevator's designed capacity is insufficient to meet the actual demand.

[0120] Preferably, in step S6, based on the implementable congestion mitigation measures, the elevator riding suggestion includes information to inform elevator users how to comply with the implementable congestion mitigation measures; or

[0121] Step S6 generates corresponding elevator riding suggestions based on the causes of congestion and the feasible congestion mitigation measures. The elevator riding suggestions include information reflecting the causes of congestion and information for informing elevator users how to act in accordance with the feasible congestion mitigation measures.

[0122] Preferably, the elevator riding suggestion also includes the expected effects on the elevator and / or the elevator users as a result of the elevator users adopting the elevator riding suggestion. The expected effects on the elevator include a reduction in elevator congestion and / or an increase in elevator transport efficiency. The expected effects on the elevator users include at least one of a reduction in the average waiting time, a reduction in the average riding time, and a reduction in the average number of stops during the ride.

[0123] Preferably, before step S7, the method further includes:

[0124] Step C1: Determine the elevator users who are the best candidates for recommendations based on the congestion relief measures.

[0125] Preferably, step C1 determines whether it is necessary to distinguish elevator users when elevator congestion is detected based on the congestion relief measures. The distinction of elevator users is achieved by the elevator user's call floor and / or destination floor, whether on the floor or inside the car.

[0126] Preferably, when it is necessary to differentiate elevator users, the method further includes the following after step C1:

[0127] Step C2: Based on the elevator users identified as the best recipients of the advice in Step C1 and the elevator operation information, determine the optimal time to inform the elevator users of the advice content.

[0128] Preferably, step C2 determines the optimal time to inform elevator users of the suggested content based on the means of distinguishing elevator users in step C1 and the elevator operation information. Attached Figure Description

[0129] To more clearly illustrate the technical solution of the present invention, the accompanying drawings used in the present invention will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0130] Figure 1 This is a schematic diagram of an embodiment of the elevator ride suggestion system of the present invention. Detailed Implementation

[0131] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0132] Example 1. Figure 1 As shown, the elevator ride suggestion system includes:

[0133] The congestion storage module is used to associate and store the causes of elevator congestion, the corresponding congestion mitigation measures, and their applicable conditions.

[0134] The information acquisition module is used to acquire congestion-related information from elevator operation information. The information categories of the congestion-related information are pre-specified according to the cause of congestion, the congestion mitigation measures, and the applicable conditions.

[0135] The congestion monitoring module is used to monitor whether the elevator is crowded based on the congestion-related information obtained by the information acquisition module.

[0136] The determination module determines, when the congestion monitoring module detects elevator congestion, the implementable congestion mitigation measures that can alleviate the current elevator congestion based on the congestion-related information and the stored content in the congestion storage module, and outputs them as implementable congestion mitigation measures.

[0137] The suggestion content generation module generates elevator riding suggestions that include the implementable congestion mitigation measures based on the implementable congestion mitigation measures.

[0138] The notification module is used to inform elevator users of the elevator riding suggestions generated by the suggestion generation module.

[0139] The elevator ride suggestion system in Example 1 stores the causes of elevator congestion, corresponding congestion mitigation measures, and their applicable conditions in a congestion storage module. A congestion monitoring module monitors elevator congestion based on congestion-related information obtained from an information acquisition module. When the elevator is congested, a determination module determines feasible congestion mitigation measures based on the congestion-related information and the stored content in the congestion storage module, and outputs these measures as feasible congestion mitigation measures. A suggestion content generation module generates ride suggestion content containing feasible congestion mitigation measures. A notification module informs elevator users of the ride suggestion. The elevator ride suggestion system in Example 1 analyzes the causes of elevator congestion and determines the elevator users who need information notification based on the analysis results. This ensures that the information notification to elevator users is more appropriate, reasonable, and accurate, enabling the system to inform elevator users of feasible congestion mitigation measures when the elevator is congested, thereby improving elevator operating efficiency and effectively reducing the incidence of car congestion.

[0140] Example 2. Based on the elevator ride suggestion system of Example 1, the determining module further includes:

[0141] The cause analysis unit analyzes the causes of elevator congestion based on the elevator operation information.

[0142] The means determination unit is used to determine the available congestion relief means based on the congestion cause output by the cause analysis unit and the congestion cause and its corresponding congestion relief means in the congestion storage module, and output them as available congestion relief means.

[0143] The judgment unit is used to determine whether the optional congestion relief method output by the means determination unit is feasible based on the congestion-related information and the applicable conditions corresponding to the congestion relief methods in the congestion storage module. When the congestion-related information meets the applicable conditions, it is determined that there is an feasible optional congestion relief method, and the optional congestion relief method output by the means determination unit is output as an feasible congestion relief method.

[0144] Example 3. Based on the elevator riding suggestion system of Example 1, the suggestion condition generation module is further configured to generate suggestion notification conditions corresponding to the riding suggestion content based on the implementable congestion mitigation measures, wherein the suggestion notification conditions include at least one of the notification recipient, notification time, and notification location of the riding suggestion;

[0145] The notification module outputs the elevator riding suggestion content according to the suggested notification conditions, thereby informing the elevator users of the elevator riding suggestion content.

[0146] Example 4. An elevator ride suggestion system based on Example 1, wherein the elevator ride suggestion system further includes a threshold storage module;

[0147] The threshold storage module stores at least one of the following: passenger capacity threshold, area threshold, weight threshold, number of passengers waiting for elevator, waiting time threshold, and riding time threshold.

[0148] The elevator operation information includes at least one of the following: the number of elevator users in the elevator car, the area occupied by elevator users in the elevator car, the weighing results output by the elevator weighing device, the number of elevator users in the waiting hall, the waiting time of elevator users, and the actual riding time of elevator users.

[0149] The congestion monitoring module determines whether the elevator is crowded based on at least one of the following relationships: the relationship between the number of elevator users in the elevator car and the threshold number of people in the car; the relationship between the area occupied by elevator users in the elevator car and the area threshold; the relationship between the weighing result output by the elevator weighing device and the weight threshold; the relationship between the number of elevator users in the waiting hall and the threshold number of people waiting for the elevator; the relationship between the waiting time of elevator users and the waiting time threshold; and the relationship between the actual riding time of elevator users and the riding time threshold.

[0150] The elevator ride suggestion system in Example 4 determines whether an elevator is crowded by factors such as the number of passengers in the car exceeding a threshold, the area occupied by passengers in the car exceeding a threshold, the weighing device result exceeding a threshold, the presence of passengers staying on the floor, and the time spent by passengers taking the elevator (including waiting time) exceeding a threshold.

[0151] Example 5. Based on the elevator ride suggestion system of Example 4, the congestion reasons include at least one of the following: large resource occupation, dispersed departure and / or destination floors of elevator users, concentrated large passenger flow, improper use of elevator users, and unreasonable elevator group management parameter settings;

[0152] The passengers who occupy large resources are those carrying large items or those whose journey takes a long time (such as wheelchair passengers, elderly passengers, etc.).

[0153] The elevator group management parameter settings include the division of service floors and the setting of peak hours.

[0154] Preferably, when the congestion monitoring module detects elevator congestion, if the elevator image acquisition device captures an image inside the elevator car showing a large item inside the elevator car or the weighing result output by the elevator weighing device is less than a threshold (because the congestion monitoring module has already determined that the elevator is congested, when the elevator starts from the waiting hall, the elevator car must be fully loaded or almost fully loaded. If the load inside the car is less than the threshold but it is fully loaded, it can only be because there is not enough space inside the car to carry more elevator users. In this case, there must be a large item inside the car), the cause of congestion output by the cause analysis module is that the elevator user is carrying a large item.

[0155] Preferably, when the congestion monitoring module detects elevator congestion, if the number of elevator users' departure floors and / or destination floors exceeds a threshold within a certain period of time, the cause of congestion output by the cause analysis module is that the elevator users' departure floors and / or destination floors are dispersed.

[0156] Preferably, when the number of elevator users in the waiting hall or the waiting time of elevator users exceeds a threshold within a unit time, or when the weighing result output by the elevator weighing device within a unit time shows that the number of times the elevator is overloaded exceeds a threshold, the cause of congestion output by the cause analysis module is a concentrated large passenger flow.

[0157] The waiting time of the elevator users is the average waiting time of all elevator users, or the longest waiting time among all elevator users.

[0158] Preferably, the elevator operation information also includes operation information reflecting the operation of the elevator by the user.

[0159] When the operation information indicates that the elevator user has performed improper operation on the elevator, the cause analysis module outputs the cause of congestion as improper use of the elevator by the user.

[0160] Example 6. Based on the elevator ride suggestion system of Example 2, when the elevator operation information of a certain elevator dispatch function of the elevator group management system, which is affected by the relevant parameters of the elevator group management system, indicates that the actual effect of the elevator dispatch function is lower than the expected effect, the cause of congestion output by the cause analysis unit is that the elevator group management parameters are set unreasonably.

[0161] Preferably, the elevator dispatching function affected by the relevant parameters of the elevator group management system is an elevator zone service, the corresponding elevator operation information is the congestion level in different zones, and the corresponding elevator group management parameter is the service area division parameter.

[0162] When the actual passenger flow difference of elevators serving different service areas exceeds a threshold, the cause of congestion output by the cause analysis module is that the service area division parameter setting is unreasonable.

[0163] Preferably, the elevator dispatching function affected by the relevant parameters of the elevator group management system is for handling peak passenger flow periods, and the corresponding elevator operation information is the elevator user's call signal and the time of its generation, and the corresponding elevator group management parameter is the peak passenger flow period.

[0164] When the actual passenger flow corresponding to the current peak passenger flow period is less than the actual passenger flow during off-peak periods (i.e., other periods that do not belong to the current peak passenger flow period parameter setting), the cause of congestion output by the cause analysis module is that the peak period parameter setting is unreasonable.

[0165] Example 7. Based on the elevator ride suggestion system of Example 3, the congestion is caused by the dispersion of elevator users' departure and / or destination floors. The congestion relief measure corresponding to this cause is to take the elevator to the nearest high-traffic floor. The applicable conditions are that there are high-traffic floors and low-traffic floors. The notification location in the suggestion notification conditions is the low-traffic floor.

[0166] When the cause of congestion is that the departure floor and / or destination floor of the elevator users are dispersed, if the means determination unit determines that the optional congestion relief means is to take the elevator to the nearest floor with high passenger flow, and determines that there are floors with high passenger flow and floors with low passenger flow based on congestion-related information, then the means determination unit outputs taking the elevator to the nearest floor with high passenger flow as an implementable congestion relief means.

[0167] The suggestion content generation module generates elevator usage suggestions, including taking the elevator to the nearest floor with high passenger flow, based on the implementable congestion mitigation measures.

[0168] The notification module will inform elevator users on the low-passenger-flow floors that if the distance between the low-passenger-flow floor and the nearest high-passenger-flow floor is less than a set number of floors, the elevator will suggest taking the elevator to the nearest high-passenger-flow floor.

[0169] Preferably, if the number of floors with low passenger flow is not less than a set number of floors from the nearest high passenger flow floor, the notification module will inform elevator users on the low passenger flow floors of the suggestion to postpone or advance their elevator ride to a less crowded time.

[0170] Preferably, the congestion-related information includes passenger flow on each floor when the elevator is congested.

[0171] Preferably, after receiving the elevator ride suggestion, the notification module outputs video or audio to the nearest high-traffic floor from the low-traffic floor as a suggestion to ride the elevator.

[0172] Preferably, the number of floors is set to 1, 2, or 3.

[0173] The elevator ride suggestion system in Example 7, when the elevator is crowded and there are floors with high passenger flow and low passenger flow, if the distance between the low passenger flow floor and the nearest high passenger flow floor is less than a set floor value, then the system outputs video or audio suggestions from the low passenger flow floor to the nearest high passenger flow floor. This can improve the elevator's operating efficiency by reducing the number of elevator car stops, thereby reducing the occurrence of car congestion. It is particularly suitable for occasions with long congestion periods, such as morning rush hour, and can effectively reduce the occurrence of car congestion.

[0174] Example 8. Based on the elevator passenger recommendation system of Example 7, the judgment unit determines the passenger flow of each floor according to the number of passengers entering and leaving the elevator car on each floor. If the number of passengers entering and leaving the elevator car when the elevator car stops at a floor for N consecutive times is greater than the set upper limit, where N is a positive integer, then the floor is a high-passenger-flow floor. If the number of passengers entering and leaving the elevator car when the elevator car stops at a floor for N consecutive times is less than the set lower limit, and the set lower limit is less than half of the set upper limit, then the floor is a low-passenger-flow floor.

[0175] Preferably, N is 1, 2, 3 or 4.

[0176] Preferably, the maximum number of passengers is set to be greater than 1.5 times the rated passenger capacity of the car.

[0177] Preferably, the notification module outputs video or audio suggestions to the nearest high-traffic floor from a low-traffic floor, including walking to the nearest high-traffic floor to take the elevator. It may also include information such as the elevator operating efficiency value that can be improved and the passenger elevator travel time that can be reduced, for example, "Your walking will improve the elevator operating efficiency by x% and reduce the passenger elevator travel time by x seconds".

[0178] Example 9. Based on the elevator ride suggestion system of Example 8, the congestion monitoring module determines that the elevator is congested if the number of passengers in the waiting area of ​​the first floor of an elevator exceeds a threshold for a set time, and records the congested floor and congestion time in the congestion database.

[0179] If the current congested floor and congestion time are regular congested floors and congestion times in the congestion database, the judgment unit determines whether there are currently high-passenger-flow floors and low-passenger-flow floors based on the passenger flow on each floor when the elevator is congested. Otherwise, it is uncertain whether there are currently high-passenger-flow floors and low-passenger-flow floors. Regular congested floors and congestion times are defined as follows: in the most recent M congestion records in the congestion database, the number of congestion records for that floor at that time exceeds a set proportion, where M is greater than the number of elevator stops F.

[0180] Preferably, the set ratio is 1 / F.

[0181] The elevator ride suggestion system in Example 9 first determines whether the congestion is accidental or regular (i.e., occurring multiple times on the same floor within the same time period). Only when congestion is regular does it determine whether there are floors with high or low passenger flow, and then outputs ride suggestions via video or audio when such floors exist. This avoids providing incorrect ride suggestions to elevator users when congestion occurs irregularly.

[0182] The elevator ride suggestion system in Example 9 analyzes the causes of elevator congestion and provides passengers with more appropriate and reasonable ride change suggestions based on the analysis results. This makes the ride change suggestions more appropriate and reasonable, improves the overall operating efficiency of the elevator, and reduces the congestion rate.

[0183] Example 10. Based on the elevator ride suggestion system of Example 9, the judgment unit, after determining that there are currently high-passenger-flow floors and low-passenger-flow floors, outputs the information of high-passenger-flow floors and low-passenger-flow floors to the notification module, and outputs the time when the elevator is not crowded or the time when the elevator is crowded to the notification module within the previous time period or the next time period of the current time each day.

[0184] The notification module, upon receiving information about floors with high and low passenger flow, outputs video or audio suggestions for taking the elevator. If the distance between a floor with low passenger flow and the nearest floor with high passenger flow is less than a set floor value (e.g., 1, 2, or 3), it outputs video or audio suggestions for taking the elevator to the nearest floor with high passenger flow. Upon receiving information about floors with low passenger flow during off-peak hours or during peak hours, it outputs video or audio suggestions for taking the elevator during off-peak hours or during peak hours.

[0185] Ideally, the first time period should be 0.5 to 3 hours, and the second time period should be 0.5 to 3 hours.

[0186] The elevator ride suggestion system in Example 10, after determining whether there are floors with high passenger flow and floors with low passenger flow, outputs the information of the high passenger flow floors and low passenger flow floors to the notification module, and outputs the elevator's uncongested time or the low passenger flow floors during the elevator's congested time within the previous or next time period of the current time each day to the notification module; after receiving the elevator's uncongested time or the low passenger flow floors during the elevator's congested time, the notification module outputs video or audio suggestions to take the elevator during the uncongested time or to take the elevator to the low passenger flow floors during the elevator's congested time, thereby achieving the effect of merging passengers and improving operational efficiency.

[0187] Example 11. Based on the elevator ride suggestion system of Example 3, the cause of congestion is large resource occupation, and the congestion relief measure corresponding to this cause is to postpone or advance the elevator ride during non-congested hours. The applicable condition is that there are non-congested hours. The notification recipients in the suggestion notification conditions are passengers with large resource occupation.

[0188] When the cause of congestion is large resource occupation, if the means determination unit determines that the optional congestion relief means is to take the elevator to the nearest floor with high passenger flow, the judgment unit will output that postponing or advancing to take the elevator during non-congestion hours is an implementable congestion relief means.

[0189] The suggestion content generation module generates elevator riding suggestions, including postponing or advancing the elevator ride to non-crowded times, based on the implementable congestion mitigation measures.

[0190] The notification module informs passengers with high resource usage about the suggestion to postpone or advance their elevator ride to a less crowded time.

[0191] Preferably, the passengers who occupy large resources are passengers carrying large items or passengers who take a long time (such as wheelchair passengers, elderly passengers, etc.).

[0192] The elevator ride suggestion system in Example 11 suggests that passengers with large resource occupancy delay or advance their elevator ride to a less crowded time to address congestion caused by such passengers. This allows multiple passengers with large resource occupancy to take the elevator together or simply avoid peak hours (i.e., the method in Reference 2).

[0193] Example 12. An elevator ride suggestion method, comprising the following steps:

[0194] Step S1: Obtain elevator operation information;

[0195] Step S2: Determine whether the elevator is currently crowded based on the elevator operation information. If so, proceed to the next step; otherwise, return to step S1.

[0196] Step S3: Analyze the elevator operation information to determine the cause of the congestion.

[0197] Step S4: Based on the cause of congestion, determine the congestion relief measures and their applicable conditions corresponding to the cause of congestion using the pre-established correspondence between the cause of congestion, congestion relief measures, and applicable conditions.

[0198] Step S5: Determine whether there is at least one implementable congestion relief measure based on the elevator operation information. The implementable congestion relief measure refers to a congestion relief measure that corresponds to the cause of congestion and whose applicable conditions are met.

[0199] Step S6: Generate elevator riding suggestions based on the implementable congestion mitigation measures;

[0200] Step S7: Output the elevator riding suggestion to the elevator user;

[0201] Step S8: Continuously monitor the current elevator congestion until the current congestion ends;

[0202] Step S9: Return to step S1.

[0203] Example 13. Based on the elevator ride suggestion method of Example 12, the method further includes the following step between step S2 and step S3:

[0204] Step A1: Based on the current time and the historical data table of congestion duration used to save past elevator congestion periods, determine whether the current elevator congestion is occasional or regular. If it is occasional, proceed to step S8; otherwise, proceed to step S3.

[0205] Preferably, the step between step S8 and step S9 further includes:

[0206] Step B1: Determine the duration of elevator congestion based on the first time the elevator congestion is detected and the end time of the current elevator congestion, and add the new duration of congestion to the historical data table of congestion duration.

[0207] Preferably, when the current time falls within a congestion duration period between 0:00 and 24:00 in the congestion duration period historical data table, and the congestion duration period appears at least m times in the n records closest to the current time in the congestion duration period historical data table, step A1 determines the current elevator congestion as regular; otherwise, it determines it as occasional. A record refers to a congestion duration period stored in the congestion duration period historical data table that represents a certain elevator congestion, where n is a positive integer, m is a positive integer less than or equal to n, and m ≥ n / 10.

[0208] Example 14. Based on the elevator riding suggestion method of Example 12, step S2 determines a congestion index to characterize the elevator congestion status according to the elevator operation information, and determines whether the elevator is currently congested according to the relationship between the congestion index and the corresponding threshold.

[0209] Preferably, the congestion index is the actual occupied resources when elevator users ride the elevator, and the threshold is the available resources that the elevator can provide to elevator users; or the congestion index is the ratio of the actual occupied resources when elevator users ride the elevator to the available resources that the elevator can provide to elevator users, or the congestion index is the difference between the available resources and the occupied resources, or the ratio of the available resources to the available resources, and the threshold is a given parameter.

[0210] Preferably, the occupied resources are the number of elevator users in the elevator car, and the available resources are the rated passenger capacity of the elevator; or the occupied resources are the actual occupied area of ​​elevator users in the elevator car, and the available resources are the car floor area available for use by elevator users; or the occupied resources are the weighing results output by the elevator weighing device, and the available resources are the rated load of the elevator; or the occupied resources are the actual number of elevator users waiting to board the elevator, and the available resources are a reasonable upper limit for the number of elevator users waiting to board the elevator; or the occupied resources are the actual waiting time or actual riding time of elevator users, and the available resources are a reasonable upper limit for the waiting time or riding time of elevator users.

[0211] Corresponding to the occupied resources, the elevator operation information includes at least one of the following: the number of elevator users in the elevator car, the area occupied by elevator users in the elevator car, the weighing results output by the elevator weighing device, the number of elevator users in the waiting hall, the waiting time of elevator users, and the actual riding time of elevator users.

[0212] Example 15. Based on the elevator riding suggestion method of Example 12, step S3 further includes the following sub-steps:

[0213] Sub-step S1: Select an unselected congestion cause from all possible congestion causes and use it as the selected congestion cause;

[0214] Sub-step S2: Determine the congestion cause index corresponding to the selected congestion cause;

[0215] Sub-step S3: Determine the basic information corresponding to the congestion cause index;

[0216] Sub-step S4: Obtain the basic information from the elevator operation information and calculate the congestion cause index;

[0217] Sub-step S5: Compare the calculated congestion cause index with its corresponding threshold.

[0218] Sub-step S6: Determine whether the selected congestion cause is the actual congestion cause based on the comparison result. If yes, proceed to sub-step S7; otherwise, return to sub-step S1.

[0219] Sub-step S7: Output the actual cause of congestion.

[0220] Preferably, sub-step S1 uses historical congestion data to count the number of elevator congestion occurrences caused by each congestion cause, and prioritizes selecting the congestion cause that occurs most frequently.

[0221] Preferably, the step between sub-step S6 and sub-step S7 further includes:

[0222] Sub-step H1: Determine if there are any unselected causes of congestion among all possible causes of congestion. If so, return to sub-step S1; otherwise, proceed to sub-step S7.

[0223] Preferably, in sub-step S7, the basic information required to calculate the congestion cause index is first analyzed, and the analysis results are used to determine whether the basic information is incorrect due to the abnormality or malfunction of the device that generates the basic information. When the device is determined to be abnormal or malfunctioning, the actual cause of congestion is determined to be the abnormality or malfunction of the relevant device, and then the actual cause of congestion is output.

[0224] Preferably, the congestion cause index is a mathematical expression that satisfies the following conditions:

[0225] Condition 1: The specific value can be calculated from the basic information in the elevator operation information;

[0226] Condition 2 corresponds one-to-one with the causes of congestion mentioned above;

[0227] Condition 3: There is a monotonically increasing relationship between the specific numerical value obtained through calculation and the probability that the elevator congestion is the cause of the congestion;

[0228] Condition 4: When its size exceeds the corresponding threshold, it can be determined that the congestion is caused by this congestion.

[0229] Preferably, the congestion is caused by the dispersion of floor calls and / or destination floors. The congestion cause index is the ratio of the total number of passengers transported to the total number of stops between the start and end points of the elevator car in a certain direction of operation, or the ratio of the total distance between the start and end points of the elevator car in a certain direction of operation to the total number of stops. The basic information included in the elevator operation information is the floor calls and destination floors, as well as the corresponding number of elevator users entering / leaving the car.

[0230] Preferably, the congestion is caused by the presence of special elevator users;

[0231] The congestion causation index is the average car floor area occupancy and / or average mass of elevator users in the elevator car. The basic information included in the elevator operation information is the number of elevator users at the time of elevator use, as well as the car floor area occupancy information and / or the actual load information of the elevator car; or, the congestion causation index is the car floor area occupancy or mass of the elevator user with the largest car floor area occupancy or mass among all elevator users, and the basic information included in the elevator operation information is the elevator user and their car floor area occupancy information or mass; or, the congestion causation index is the number of elevator users whose car floor area occupancy or mass exceeds a threshold. The number of elevators (with a corresponding threshold of 0, thus determining whether at least one exists by comparing with the threshold), the elevator operation information includes elevator users and their car floor area occupancy information or their mass, or the cause of congestion is insufficient design capacity of the elevator; the congestion cause index is the ratio of the elevator's design capacity to the actual capacity demand of the elevator, or the ratio of the difference between the actual capacity demand of the elevator and the elevator's design capacity to the actual capacity demand of the elevator; the elevator operation information includes elevator user information that needs to take the elevator, and the actual capacity demand of the elevator is obtained after appropriate processing of the elevator user information that needs to take the elevator.

[0232] Example 16. Based on the elevator riding suggestion method of Example 12, when there are multiple elevators and an elevator group management system is configured, the cause of congestion is that the parameters of the group management system are not set reasonably. The congestion cause index is the maximum load rate difference between the load rates of each elevator when it departs from the congested floor in the same direction of operation. The elevator operation information includes elevator load rate information.

[0233] Example 17. Based on the elevator riding suggestion method of Example 12, step S5 determines the implementation of congestion mitigation measures according to the following steps:

[0234] Step D1: Select an unselected congestion relief method from all congestion relief methods corresponding to the cause of congestion, and use the selected congestion relief method as the chosen congestion relief method;

[0235] Step D2: Determine the basic information required to determine whether the selected congestion relief measure is valid based on the applicable conditions corresponding to the selected congestion relief measure;

[0236] Step D3: Use the basic information contained in the elevator operation information to determine whether the applicable conditions corresponding to the selected congestion relief method are met. If they are met, the selected congestion relief method is used as the congestion relief method and output, and the process ends; otherwise, proceed to step D4.

[0237] Step D4: Determine if there are still unselected congestion relief measures. If so, return to step D1; otherwise, output a notification message that no such congestion relief measure exists and end the process.

[0238] Preferably, step D1, when making the selection, further includes the following sub-steps:

[0239] Sub-step D1-1: Based on the congestion cause, determine each congestion relief measure corresponding to the congestion cause using the congestion cause-congestion relief measure-applicable condition correspondence relationship;

[0240] Sub-step D1-2: Search and count the number of times each congestion mitigation measure was implemented as an implementable congestion mitigation measure when congestion occurred due to this congestion cause in the historical data.

[0241] Sub-steps D1-3: Select the congestion relief method with the highest number of implementations from all unselected congestion relief methods as the selected congestion relief method.

[0242] Preferably, the congestion is caused by the dispersion of elevator users' departure and / or destination floors; congestion mitigation measures corresponding to this cause include:

[0243] 1) The applicable conditions for elevator users to walk to the nearest high-traffic floor to take the elevator are: a) There are high-traffic floors and low-traffic floors among the elevator user's departure floor and / or destination floor; b) The distance between one of the high-traffic floors and / or low-traffic floors and the other of the nearest high-traffic floors and / or low-traffic floors does not exceed a threshold (Note: This can be that only the departure floor has high and low traffic and the distance between the high and low traffic floors is less than the threshold, or only the destination floor has high and low traffic and the distance between the high and low traffic floors is less than the threshold, or the high-traffic floors and low-traffic floors belong to different departure and destination floors and the distance is less than the threshold), or there is also the condition c) The travel distance corresponding to a single elevator stop (i.e., the quotient of the total travel distance of the elevator and the number of stops within a certain period of time) is less than the threshold; Step D3 analyzes and determines whether the above applicable conditions are met based on the elevator user registration information in the elevator operation information and / or the weighing results (i.e., basic information) of the weighing device used to detect the load in the elevator car when the elevator starts at each floor.

[0244] 2) The applicable conditions for elevator users to change their boarding time are: a) the current elevator congestion is a regular phenomenon (this can be omitted when the aforementioned steps include judging whether the congestion is regular), b) the time interval between the current time and the start or end time of the historical congestion period corresponding to the current congestion is less than a threshold, or the condition c) there are elevator users who frequently take the elevator at this time; step D3 analyzes and determines whether the above applicable conditions are met based on the current time (when congestion is distinguished by floor) (i.e., basic information) contained in the elevator operation information.

[0245] Preferably, when the applicable conditions of the above two congestion relief methods are met simultaneously, step D3 selects the congestion relief method according to the attributes of the elevator users.

[0246] Preferably, step D3 directly determines the elevator user's attributes based on the elevator operation information (such as based on the IC card carried by the passenger, video images, etc.), or infers the elevator user's attributes based on the attributes of the building where the elevator is located and / or the current time. The attributes refer to whether the elevator user is suitable for walking or whether they are time-sensitive.

[0247] Note: When both of the above congestion relief methods are applicable, the choice can be made based on the building's characteristics or the users' characteristics. For example, in office buildings, users are generally healthy and mobile, so the first method is preferred, and the second method should only be used if the first method's conditions are not met. In residential buildings, the likelihood of elderly or frail users is much higher than in office buildings, and their need for specific travel times is relatively less stringent. In this case, the second method should be prioritized, and the first method should only be considered if the second method's conditions are not met. Of course, besides building characteristics, the current time of day can also be considered. For example, in residential buildings, the first method is preferred for peak commuting hours, while the second method is preferred for other peak traffic times.

[0248] Preferably, the passenger flow on each floor is determined based on the number of elevator users entering the car and the number of elevator users leaving the car (to include special passengers such as robots). If the number of elevator users entering and / or leaving the car during N consecutive stops at a certain floor is greater than a set upper limit value, where N is a positive integer, then that floor is identified as a high-passenger-flow floor. If the number of elevator users entering and leaving the car during N consecutive stops at a certain floor is less than a set lower limit value, then that floor is identified as a low-passenger-flow floor.

[0249] Preferably, the elevator operation information includes the number of elevator users waiting to ride the elevator on each floor and their waiting time. When the number of elevator users waiting to ride the elevator on a certain floor exceeds a threshold, or when the number of elevator users waiting to ride the elevator on a certain floor exceeds the quantity threshold and the duration of this phenomenon exceeds the time threshold, that floor is identified as a high-traffic floor. Conversely, when the number of elevator users waiting to ride the elevator on a certain floor is less than the threshold, or when the number of elevator users waiting to ride the elevator on a certain floor is less than the quantity threshold and the duration of this phenomenon is less than the time threshold, that floor is identified as a low-traffic floor.

[0250] Ideally, in addition to defining floors with high passenger flow and floors with low passenger flow, a regularity constraint based on historical data should be added.

[0251] Preferably, the cause of congestion is high resource consumption, and the corresponding congestion mitigation measures are:

[0252] 1) It is recommended that elevator users change their elevator ride times. The applicable conditions are: a) There are non-crowded periods; b) The time interval between the current time and the non-crowded period is less than the time threshold. Step D3 analyzes and determines whether the above applicable conditions are met based on the elevator's historical data (i.e., crowded period information).

[0253] 2) It is recommended that elevator users change their elevator ride times and share the elevator ride with other users of high-resource elevators (to reduce interference with ordinary elevator users). The applicable conditions are: a) There are non-crowded periods; b) The time interval between the current time and the non-crowded period is less than the time threshold; c) There are other users of high-resource elevators during the non-crowded period. Step D3 also analyzes and confirms whether the applicable conditions are met based on historical elevator data (crowded period information and information on users of high-resource elevators during the corresponding period (resource occupancy information and elevator ride time distribution information)).

[0254] Ideally, based on the above applicable conditions, a regularity requirement is added, with the aim of ensuring that the applicable conditions for the changed elevator time do not apply when elevator users take the elevator for the first time.

[0255] Preferably, the cause of congestion is unreasonable parameter settings in the group management system. The congestion mitigation measure corresponding to this cause is to report the unreasonable parameter settings in the group management system to the elevator-related parties (property management, maintenance, or manufacturer) (preferably including phenomena or data that directly indicate the unreasonableness of the current parameters). The applicable condition is that there is a way to report information to the elevator-related parties (property management, maintenance, or manufacturer). Step D3 determines whether the applicable condition is met based on the stored information feedback channel information.

[0256] Preferably, the cause of congestion is that the elevator's designed capacity is insufficient to meet the actual demand (the judgment method is: statistically analyze the actual demand for the elevator, and the statistical results show that the actual demand for the elevator exceeds the upper limit of the elevator's designed capacity). The congestion mitigation measure corresponding to this cause is: proposing an upgrade and renovation suggestion aimed at improving the elevator's capacity (preferably while providing phenomena or data that indicate that the elevator's capacity does not meet the demand). The corresponding applicable condition is: the cause of congestion is that the elevator's designed capacity is insufficient to meet the actual demand.

[0257] Example 18. Based on the elevator riding suggestion method of Example 12, step S6, according to the implementable congestion mitigation measures, includes information for informing elevator users how to comply with the implementable congestion mitigation measures; or

[0258] Step S6 generates corresponding elevator riding suggestions based on the causes of congestion and the feasible congestion mitigation measures. The elevator riding suggestions include information reflecting the causes of congestion and information for informing elevator users how to act in accordance with the feasible congestion mitigation measures.

[0259] Preferably, the elevator riding suggestion also includes the expected effects on the elevator and / or elevator users resulting from the elevator users adopting the elevator riding suggestion (i.e., implementing congestion mitigation measures). The expected effects on the elevator include a reduction in elevator congestion (which may be achieved using congestion indicators) and / or an increase in elevator transport efficiency (such as the number of elevator users transported and the distance traveled per unit time). The expected effects on elevator users include at least one of a reduction in the average waiting time, a reduction in the average riding time, and a reduction in the average number of stops during a ride.

[0260] Example 19. The elevator ride recommendation method based on Example 12, prior to step S7, further includes:

[0261] Step C1: Determine the elevator users who are the best candidates for recommendations based on the congestion relief measures.

[0262] Preferably, the method of determining whether it is necessary to differentiate elevator users when elevator congestion is detected based on the congestion mitigation measures (e.g., for a congestion mitigation measure that requires elevator upgrades or renovations, the suggested notification recipients should be differentiated based on the elevator users, and all elevator users can be notified; for a congestion mitigation measure that requires elevator users on floors with low passenger flow to walk to the nearest floor with high passenger flow, elevator users should be differentiated, and only elevator users on floors with low passenger flow should be notified). The differentiation of elevator users can be achieved by using the floor call floor and / or destination floor of the elevator user, on the floor or inside the car.

[0263] Preferably, when it is necessary to differentiate elevator users, the method further includes the following after step C1:

[0264] Step C2: Based on the elevator users identified as the best recipients of the advice in Step C1 and the elevator operation information, determine the optimal time to inform the elevator users of the advice content.

[0265] Preferably, step C2 determines the optimal time to inform the elevator user of the suggested content based on the means of distinguishing elevator users in step C1 (i.e., the elevator user's floor call and / or destination floor, on the floor or inside the car) and the elevator operation information.

[0266] Preferably, in step S4, when obtaining the calculation result and determining the cause of congestion based on the calculation result, the basic information on which the calculation depends (such as the weighing value output by the weighing device) is incorrect due to the abnormality or malfunction of the device that generates the basic information. If the abnormality or malfunction of the device is determined, the elevator congestion is determined to be caused by the abnormality or malfunction of the relevant device.

[0267] For example, elevator operation information is the mass of elevator users inside the car, i.e. the weighing value generated by the weighing device. When the weighing device malfunctions or is abnormal, causing its output weighing value to be much greater than the actual load value, the calculated average mass of elevator users or average car floor area occupancy is too large (meaning there are few passengers in the car). It is wrong to simply conclude that there are special elevator users in this way.

[0268] Similarly, for two elevators serving the upper and lower floors respectively, if the weighing device of one elevator malfunctions or malfunctions, causing its output value to be much greater than the actual load, and the load inside the elevator car is much lower than the rated load, an overload signal will be issued, preventing further increases in the number of elevator users inside the car. Therefore, each time the elevator starts, the actual number of users transported is far less than the rated passenger capacity. If one simply judges whether the elevator congestion is due to an unreasonable group management system setting based on the relationship between the maximum load rate difference and the threshold, it would be determined that the elevator group management system's unreasonable division of the service floors for the two elevators leads to too many waiting passengers and too few passengers in the elevator car for the one with the malfunctioning weighing device. Clearly, such a cause of congestion is incorrect. To avoid this potential misjudgment, the attributes and characteristics of the device generating the basic information should be considered, along with auxiliary information, to determine whether the device is malfunctioning or malfunctioning. For weighing devices, if there are many passengers waiting for the elevator and the elevator frequently issues overload signals and continuously receives excessive average mass or average car floor area occupancy, or if the maximum load rate difference exceeds the threshold, it can be determined that the weighing device is abnormal or malfunctioning. In this case, the congestion is caused by the device malfunction rather than by special elevator users or unreasonable group management parameter settings.

[0269] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
