Description

Technical Field

[0001] This invention relates to the field of elevator technology, and more specifically to an elevator dispatching system for elevator grouping. Background Technology

[0002] In situations where there are multiple elevators, an elevator group management system is usually installed to improve elevator operating efficiency.

[0003] Currently, most elevator group management systems adopt grouping strategies to improve elevator operating efficiency. One approach is to divide the building's floors into several consecutive floor zones based on the distribution of passengers' (destination) floors, and assign several service elevators to each floor zone. These designated elevators only stop at the floors within their corresponding floor zones, thereby improving elevator operating efficiency; as in document CN03826866.3. Another approach is to group passengers according to certain criteria and then assign responsive elevators to passengers based on the grouping results. For example, document CN201410384349.X proposes grouping passengers based on their logged-in destination floors during congestion, setting standby positions for passengers belonging to each passenger group, and assigning responsive elevators to each passenger group.

[0004] To meet passengers' personalized elevator riding needs (such as their preference for the temperature inside the elevator car), elevator group management systems have developed targeted solutions. For example, document CN202311212458.9 proposes appropriately assigning responsive elevators to waiting passengers with different desired temperature settings inside the elevator car. This ensures that the temperature inside the car remains consistent with the passengers' expectations during their ride, thereby improving the passenger experience. Clearly, this solution first assigns responsive elevators to passengers and then sets the desired car temperature for those elevators based on their preferences—a passenger-centric, elevator-secondary approach.

[0005] However, because this scheme requires autonomously analyzing and determining passengers' desired temperatures before grouping them, errors in temperature determination can lead to inappropriate grouping. Furthermore, the range of temperature variations passengers expect during their elevator rides is relatively small, and the temperature settings for each grouped passenger's car typically only include a few predetermined temperatures, such as two high and three low, or high, medium, and low temperatures. In this case, it's entirely possible to pre-set elevators with different temperatures, allowing passengers to choose the appropriate one – a passenger-selective elevator approach. The elevator simply needs to assign a suitable elevator from those that meet the passenger's chosen car temperature. Clearly, this is an elevator-centric, passenger-secondary approach. Summary of the Invention

[0006] The technical problem to be solved by this invention is how to provide a technical solution that can both meet the personalized elevator riding needs of passengers and make elevator group dispatching operation simple, accurate and convenient.

[0007] To solve the above-mentioned technical problems, the present invention provides an elevator dispatching system for elevator grouping, comprising:

[0008] The grouping module is used to group elevators according to passengers' riding preferences, resulting in multiple elevator groups;

[0009] A module is provided for providing passengers with a means to input group-specific operations, wherein the group-specific operation refers to the operation by which the passenger specifies the elevator group he or she will take;

[0010] The receiving module is used to receive the group-specified operation information and elevator call signals from passengers.

[0011] The allocation module is used to allocate a responding elevator to the call signal according to the group-specified operation information;

[0012] The notification module is used to inform passengers of elevator group information or response information specified by the group-designated operation.

[0013] Preferably, the grouping module divides the elevators within the coverage area of ​​the elevator dispatching system into multiple groups in an adaptive manner according to preset triggering conditions.

[0014] Preferably, the steps for setting the triggering conditions include: Step 1, determining all possible passenger elevator preferences; Step 2, analyzing the influencing factors of elevator preferences; Step 3, determining the measurable and obtainable basic physical quantities of the influencing factors, and establishing a mathematical model with the basic physical quantities as input and the influencing factors as output; Step 4, determining the grouping criteria for the grouping module to group elevators based on the influencing factors; Step 5, setting the triggering conditions for grouping elevators based on the mathematical module and the grouping criteria.

[0015] Preferably, the elevator dispatching system further includes: a storage module for storing triggering conditions for grouping elevators; a first monitoring module for monitoring whether the triggering conditions are met; when the first monitoring module detects that the triggering conditions are met, the grouping module performs grouping of elevators.

[0016] Preferably, the first monitoring module acquires basic physical quantity data, determines whether the triggering condition is met based on the basic physical quantity data, and outputs a monitoring result indicating that the triggering condition is met when the triggering condition is determined to be met.

[0017] Preferably, the elevator dispatching system further includes: a second monitoring module, used to determine whether to activate the first monitoring module to monitor the triggering conditions and which triggering conditions to monitor based on the pre-established correspondence between elevator preferences and triggering conditions.

[0018] Preferably, the elevator dispatching system further includes: a selection module, which selects the elevator preference whose trigger condition is met when the second monitoring module starts the first monitoring module to monitor the trigger condition, and the first monitoring module detects that the trigger condition corresponding to multiple elevator preferences is met at the same time, and selects the elevator preference whose trigger condition is met as the basis for implementing group control of the elevator.

[0019] Preferably, the selection module sorts the elevator preferences based on the negative externalities of the triggering conditions, and then selects the elevator preferences for grouping the elevators in order of increasing externalities. The grouping module groups the elevators according to the selected elevator preferences to obtain elevator groups. When the total negative externalities of passengers exceed the positive externalities for the first time, the remaining selected elevator preferences, except for the last selected elevator preference, are retained as the final selected elevator preferences, which are then used by the grouping module to implement grouping according to the final selected elevator preferences. The negative externalities refer to the reduction in the elevator experience brought to passengers by the implementation of elevator grouping, and the positive externalities refer to the improvement in the elevator experience brought to passengers by the implementation of elevator grouping.

[0020] Preferably, the elevator dispatching system further includes a third monitoring module, used to monitor the differences in elevator operation and / or passenger waiting conditions among different elevator groups after grouping, and to determine whether the elevator grouping needs to be adjusted based on the monitored differences, and to further determine how to adjust the grouping if necessary.

[0021] Preferably, the providing module determines whether it is used exclusively by a passenger or shared by multiple passengers. When providing passengers with a means to input a group to specify an operation, it presents elevator preference options that passengers can specify, and the elevator preference options correspond to the current grouping criteria of the elevator group.

[0022] Technical effect

[0023] The proposed solution pre-groups elevators according to passengers' riding preferences, receives and controls the elevators according to the group assignments of passengers, thus satisfying passengers' personalized riding needs and making elevator grouping and dispatching simple, accurate and convenient. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0025] Figure 1 This is a schematic diagram of the elevator dispatching system structure in Example 1;

[0026] Figure 2 This is a floor plan of an elevator layout for a special case of Example 7. Detailed Implementation

[0027] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can fully understand other advantages and technical effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific embodiments, and the details in this specification can also be applied based on different viewpoints, with various modifications or changes made without departing from the overall design concept of the invention. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other. The following exemplary embodiments of the present invention can be implemented in many different forms and should not be construed as being limited to the specific embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary embodiments to those skilled in the art.

[0028] Example 1

[0029] like Figure 1 As shown, this embodiment provides an elevator dispatching system for elevator grouping, including:

[0030] The grouping module is used to group elevators according to passengers' riding preferences, resulting in multiple elevator groups;

[0031] A module is provided for providing passengers with a means to input group-specific operations, wherein the group-specific operation refers to the operation by which the passenger specifies the elevator group he or she will take;

[0032] The receiving module is used to receive the group-specified operation information and elevator call signals from passengers.

[0033] The allocation module is used to allocate a responding elevator to the call signal according to the group-specified operation information;

[0034] The notification module is used to inform passengers of elevator group information or response information specified by the group-designated operation.

[0035] Elevator riding preferences include at least one of the following: car temperature preference, car illumination preference, car atmosphere preference (lighting, decoration, background music, media played on the display screen), car crowding preference, co-riding preference (whether pets can ride together, etc.), and elevator control performance preference (small acceleration / deceleration, rated speed).

[0036] For preferences regarding elevator control performance, such as: for elderly, frail, or passengers who are more sensitive to weightlessness and overload, elevators with relatively small acceleration (deceleration) or equipped with weighing devices can be assigned to them; the control can also be improved so that the response elevator for these passengers slows down in advance when passing other elevators (or counterweights) to reduce the car shaking caused by airflow caused by the passing of cars in the shaft, and so on.

[0037] Example 2

[0038] This embodiment further explains the grouping module based on Embodiment 1.

[0039] The grouping module handles elevator grouping operations in the following two ways:

[0040] Scenario 1: Grouping is not changed after grouping. For example, property management personnel or other relevant staff directly designate elevator groups and input the grouping results into the system in a certain way;

[0041] Scenario 2: Grouping is performed adaptively by the grouping module. That is, the grouping module divides the elevators within the coverage area of ​​the elevator dispatching system into multiple groups in an adaptive manner according to preset trigger conditions.

[0042] It should be noted that the grouping results from the grouping module must contain at least two elevator groups, and each elevator group must correspond to at least one elevator. The grouping results here include the number of elevator groups, their categories, and the correspondence between elevator groups and elevators.

[0043] The adaptive grouping in Case 2 will be explained in detail below.

[0044] The adaptive grouping here refers to the grouping module autonomously dividing each elevator within the coverage area of ​​the elevator dispatching system into groups based on triggering conditions.

[0045] The triggering conditions here include one or more of the following: current season, weather, current time, passenger flow, differences in car crowding levels between different elevator groups, number of people waiting for the elevator, average, longest, or median waiting time, and overall elevator efficiency for passengers. Alternatively, when changing the elevator's group, the relevant conditions may also include the costs incurred for changing the group (such as energy consumption, impact on component lifespan, etc.).

[0046] The steps for setting the triggering conditions include:

[0047] Step 1: Determine all possible elevator preferences of passengers;

[0048] Step 2: Analyze the factors influencing elevator riding preferences;

[0049] Step 3: Determine the measurable and obtainable basic physical quantities of the influencing factors, and establish a mathematical model with the basic physical quantities as input and the influencing factors as output;

[0050] Step 4: Determine the grouping criteria for the grouping module to group elevators based on the aforementioned influencing factors;

[0051] Step 5: Set the trigger conditions for grouping elevators according to the mathematical module and the grouping benchmark.

[0052] Taking the preference for crowded elevator cars as an example, the following explanation is provided:

[0053] The influencing factor is the car load rate; the basic physical quantity is the car load (not considering individual passengers carrying large objects); the mathematical model is: load rate = actual car load / elevator rated load * 100%;

[0054] Grouping criteria: If it is necessary to classify elevators into three categories: very crowded, moderately crowded, and relatively relaxed, the grouping criteria can be set as follows: car load rate not less than 95%, car load rate between 85% and 95%, and car load rate less than 85%.

[0055] Triggering condition: When the actual load rate of the elevator (such as the average of several load rates over a period of time) exceeds 85% (or slightly higher than 85%, such as 90%), since passengers often give up riding the elevator due to overcrowding, grouping of elevators based on passenger preferences (here, car overcrowding) should be initiated. In this case, grouping is implemented when the actual load rate of the elevator exceeds 85%. Since directly monitoring the actual load rate of the elevator is inconvenient, it can be converted into the actual load of the elevator car using a mathematical model, that is, the actual load corresponding to the actual load rate of 85%. When the actual load of the elevator (the average of several load rates over a period of time) detected by the monitoring module exceeds the load, grouping is initiated. Therefore, the triggering condition is that the actual load of the elevator is greater than the load.

[0056] For example: if the passenger's preference is for the temperature inside the elevator car, then:

[0057] The influencing factor is the temperature difference between the inside and outside of the car (or the temperature inside the car);

[0058] The basic physical quantities are the temperature inside the elevator car and the temperature in the waiting hall (current air temperature) (when the influencing factor is the temperature inside the elevator car, the basic physical quantity is still the temperature inside the elevator car);

[0059] Mathematical model: Temperature difference between inside and outside the car = Current outside air temperature - Temperature inside the car (Temperature inside the car = Detected temperature value inside the car);

[0060] Grouping Criteria: Assuming the elevator needs to be divided into two groups based on temperature difference (large and small temperature differences, or high and low temperature cars), the grouping criteria are set as follows: a car is considered cool when the temperature difference does not exceed 8℃ (or a car with an interior temperature not exceeding 25℃); otherwise, it is considered a comfortable car. Grouping is implemented when the temperature difference between the inside and outside of the elevator car exceeds 8℃ (or when the interior temperature exceeds 25℃). Therefore, the trigger condition is: whether the temperature difference between the inside and outside of the elevator car exceeds 8℃ (or whether the interior temperature exceeds 25℃). Other passenger preferences (such as interior temperature preferences) can be implemented similarly.

[0061] The elevator dispatching system further includes: a storage module for storing trigger conditions for grouping elevators; a first monitoring module for monitoring whether the trigger conditions are met; when the first monitoring module detects that the trigger conditions are met, the grouping module implements the grouping of elevators.

[0062] The first monitoring module acquires basic physical quantity data and determines whether the triggering condition is met based on the basic physical quantity data. When the triggering condition is determined to be met, the monitoring result indicating that the triggering condition is met is output.

[0063] Example 3

[0064] This embodiment is a further explanation based on embodiment 2.

[0065] The elevator dispatching system further includes a second monitoring module, which is used to determine whether to activate the first monitoring module to monitor the triggering conditions and which triggering conditions to monitor based on the pre-established correspondence between elevator preferences and triggering conditions.

[0066] For example, the trigger condition for the preference for riding in crowded elevator cars can be set as: before peak hours / or a certain period of time. During such periods, passenger flow is often relatively high, and the elevator car may become quite crowded at certain times. At this time, passengers are usually not in a particular hurry to take the elevator (e.g., they are not worried about being late for work and will endure a crowded car), and may choose to wait for the next elevator instead of riding in a crowded car. Therefore, the second monitoring module will then start monitoring the preference for riding in crowded elevator cars, and only then will the first monitoring module begin monitoring the trigger conditions for this preference.

[0067] The same applies to the preference for temperature inside the elevator car. The precondition can be set as follows: it is currently summer and the current outside temperature reaches or exceeds 25°C. At this time, the second monitoring module will start to pay attention to the preference for temperature inside the elevator car, and then the first monitoring module will start to monitor the triggering conditions for the preference for temperature inside the elevator car (such as the actual temperature inside the car and the outside temperature, so as to determine the temperature difference).

[0068] Preferably, the elevator dispatching system further includes: a selection module, which selects the elevator preference whose trigger condition is met when the second monitoring module activates the first monitoring module to monitor the trigger condition, and the first monitoring module detects that the trigger condition corresponding to multiple elevator preferences is met simultaneously.

[0069] The selection module sorts the elevator preferences based on the negative externalities of the trigger conditions, and then selects the elevator preferences for grouping elevators in ascending order of externality. The grouping module groups elevators according to the selected elevator preferences to obtain elevator groups. When the total negative externalities of passengers exceed the positive externalities for the first time, the remaining selected elevator preferences, except for the last selected elevator preference, are retained as the final selected elevator preferences for the grouping module to implement grouping according to the final selected elevator preferences. The negative externalities refer to the reduction in the elevator experience for passengers (including the elevator preferences on which the group is based and other passengers besides those corresponding to the elevator preferences on which the group is based) due to the implementation of elevator grouping. The positive externalities refer to the improvement in the elevator experience for passengers (including the elevator preferences on which the group is based and other passengers besides those corresponding to the elevator preferences on which the group is based) due to the implementation of elevator grouping.

[0070] An example of a negative externality is the number of elevator groups after grouping, because the more elevator groups there are, the heavier the burden on passengers to identify when taking the elevator; examples of positive externalities are obvious, such as satisfying the personalized elevator needs of passengers whose elevator preferences are based on grouping.

[0071] Example 4

[0072] This embodiment is a further explanation based on embodiment 2 or embodiment 3.

[0073] The elevator dispatching system also includes a third monitoring module, which monitors the differences in elevator operation and / or passenger waiting conditions among different elevator groups after grouping, and determines whether the elevator grouping needs to be adjusted based on the monitored differences, and further determines how to adjust the grouping if necessary.

[0074] Elevator operation status mainly refers to the actual load rate of the car in different elevator groups, passenger transport efficiency, number of intermediate stops and travel time of the elevator from the time a passenger enters the car to the time the passenger arrives at their destination floor, etc. Passenger waiting status mainly refers to the waiting time and the number of people waiting for the elevator.

[0075] The third monitoring module uses at least one of the following methods to adjust the elevator grouping:

[0076] Method 1: Change the elevator preference used by the grouping module to implement grouping;

[0077] Method 2: Change the number of groups obtained when the grouping module groups based on a certain elevator preference;

[0078] Method 3: Change the grouping criteria when the grouping module groups users based on a certain elevator preference.

[0079] For adaptive grouping, when it is determined that the grouping results need to be adjusted based on the triggering conditions, the grouping of all elevators is usually not changed at once, but only the grouping of some elevators is adjusted. Therefore, the method of the third monitoring module to adjust the elevator group is as follows: identify the elevators to be changed whose grouping needs to be changed; determine whether the elevators to be changed can be grouped; if they can be grouped, change the elevators to be changed from the previous grouping to the new grouping.

[0080] The third monitoring module determines whether the elevators to be changed can be grouped according to the following steps:

[0081] Step S1: Determine the grouping basis corresponding to the changed grouping;

[0082] Step S2: Determine the basic information corresponding to the grouping criteria;

[0083] Step S3: Obtain the basic information corresponding to the changed group;

[0084] Step S4: Determine whether it is technically feasible to perform group change operations on the elevators to be changed based on the basic information.

[0085] For a given grouping adjustment, the feasible adjustment plan (i.e., which elevators are changed from the previous grouping to the new grouping) is usually not unique.

[0086] When there is more than one option for adjusting the elevator group, the third monitoring module selects an adjustment option according to at least one of the following principles:

[0087] Principle 1: After adjustment, elevators belonging to the same group will be placed closer to each other;

[0088] Principle 2: Minimize the waiting time required to implement group adjustments.

[0089] The following example illustrates the above content:

[0090] Assume an office building has six elevators numbered #1 to #6. When passengers enter the building through the main entrance and arrive at the elevator lobby, elevators #1 to #3 are located on the left side of the lobby, and elevators #4 to #6 are located on the right side. Since it is summer, the six elevators are divided into two groups based on the set temperature inside their cars: a normal temperature group and a slightly lower temperature group. Initially, elevators #1 to #3 on the left side of the lobby belong to the normal temperature group, while elevators #4 to #6 on the right side belong to the slightly lower temperature group.

[0091] The third monitoring module has now discovered through analysis that the elevators in the slightly lower temperature group are significantly more crowded when departing from the lobby on the first floor than the elevators in the normal temperature group. This indicates that passengers have a significantly higher demand for elevators in the slightly lower temperature group than for elevators in the normal temperature group. In order to better serve passengers, the third monitoring module has decided to adjust the number of elevators in the slightly lower temperature group and the normal temperature group. Specifically, the number of elevators in the slightly lower temperature group will be increased from 3 to 4, and the number of elevators in the normal temperature group will be increased from 3 to 2. This requires selecting one elevator as the elevator to be changed and regrouping it from the normal temperature group to the slightly lower temperature group.

[0092] In this example, the specific steps for adjusting the elevator group are as follows:

[0093] S1. Determine the grouping basis corresponding to the changed grouping; obviously, the grouping basis here is the temperature inside the car;

[0094] S2. Based on the basic information corresponding to the grouping criteria, the basic information is the information that can be obtained and on which the grouping change operation of the elevator being grouped into the changed group is technically feasible. The basic information here is the temperature inside the elevator car (note that the grouping criteria are not always the same as the basic information. In some cases, the grouping criteria may not be directly available and may need to be obtained through indirect calculations. In this case, the basic data is the dependent variable in the calculation formula for the grouping criteria).

[0095] S3. Obtain the basic information corresponding to the changed group; this involves obtaining the temperature inside the elevator car.

[0096] S4. Based on the basic information, determine whether the grouping change operation of the elevator to the changed group is technically feasible. Specifically:

[0097] Among the elevators originally in the normal temperature group, only elevators #4 and #5 are equipped with high-powered air conditioners, which can lower their normal temperature and maintain it at a slightly lower temperature. Therefore, from the perspective of elevator configuration, #4 or #5 can be selected as the elevator to be changed. From the elevator operation information, elevator #5 is currently descending towards the 1st floor and will stop there in about 5 seconds. It would take at least 30 seconds for the temperature inside elevator #4 to be adjusted from its current temperature (normal temperature) to a slightly lower temperature. Elevator #4 takes 40 seconds to reach the lobby on the 1st floor, and it would also take 30 seconds for its temperature inside the car to be adjusted from its current temperature (normal temperature) to a slightly lower temperature. Therefore, from the perspective of elevator operation information, elevator #5 is not technically feasible, while elevator #4 is technically feasible. At the same time, elevator #4 is relatively close to the other elevators in the slightly lower temperature group, and it is also close to elevators #5 or #6 in the normal temperature group. Therefore, elevator #4 can be selected as the elevator to be changed.

[0098] Example 5

[0099] This embodiment further explains the provided modules based on embodiment 1.

[0100] The modules are provided in two types: one is for individual use by a passenger, and the other is for sharing by multiple passengers.

[0101] For situations where passengers have exclusive access, a typical example is when a passenger registers their elevator call signal using a mobile terminal. The elevator call software on the mobile terminal directly presents the passenger with options to specify their elevator preferences (i.e., the grouping criteria corresponding to the elevator group). Note that the options should correspond one-to-one with the elevator group. Furthermore, when the grouping module adjusts the elevator group, causing a change in the category of the adjusted elevator group (when the number of elevator groups changes, the category of the elevator group will inevitably change as well, since each elevator group corresponds to only one elevator group category, and elevator groups of the same category will inevitably be merged into one elevator group), the passenger should be promptly notified via the mobile terminal so that the passenger receives the correct elevator group information when registering their elevator call signal.

[0102] There are two ways to inform people here:

[0103] Method A: Obtain and update the elevator group information of the registered elevators from the cloud platform in real time; The passenger's mobile terminal obtains and updates the elevator group information of the registered elevators from the cloud platform in real time (via the public network ISP) based on the pre-registered elevator information. This ensures that the elevator group information presented to the passenger by the software is the latest and correct every time the passenger opens the software to register the elevator call signal.

[0104] Method B: Establish a communication connection (such as Bluetooth) between the mobile terminal and the elevator only when the distance between the mobile terminal and the elevator is less than a distance threshold, and use the established communication connection to obtain elevator group information from the elevator system.

[0105] In Method B, when the providing module receives new elevator group grouping information, if the passenger has not yet registered an elevator call signal, it only updates the elevator group grouping information in the mobile terminal and presents the updated elevator group grouping information to the passenger when they register an elevator call signal later. If the passenger has already registered an elevator call signal before the communication connection between the mobile terminal and the elevator is established, after updating the elevator group grouping information in the mobile terminal, it compares whether the elevator group grouping information before and after the update affects the passenger's elevator group designation. If it does affect the designation (such as the elevator group originally designated by the passenger no longer existing and / or the number of elevators in the elevator group changing), it prompts the passenger to make changes or confirm. Otherwise, it does not take any action.

[0106] In cases where passengers share elevators, elevator grouping information needs to be communicated to passengers in an appropriate manner based on the specific circumstances.

[0107] When the means by which the providing module provides the passenger with the input group specified operation is through the elevator call signal registration device, and there is no corresponding relationship between the elevator call signal registration device and the individual group, the elevator call signal registration device presents the passenger with elevator preference options that the passenger can specify, and the elevator preference options correspond to the current grouping basis of the elevator group, or automatically specify the default elevator group for the passenger based on historical data or passenger attribute information.

[0108] When there are multiple elevator call signal registration devices, and each elevator call signal registration device corresponds to an elevator group, the elevator call signal registration device presents the corresponding elevator group information to the passenger. The passenger selects the elevator call signal registration device corresponding to the elevator group they want to specify to register an elevator call signal that matches their riding preference. The elevator system determines the elevator call signal registration device that sends the elevator call signal to the passenger and determines the elevator group information specified by the passenger based on the correspondence between the device and the elevator group.

[0109] Using the same example from the aforementioned embodiments, if two elevator call registration devices are installed at the elevator lobby entrance, and it is pre-set that the left elevator call registration device will be assigned to the slightly lower temperature elevator group and the right elevator call registration device will be assigned to the normal temperature elevator group, then passengers implicitly specify the elevator group when registering their call signals. It should be noted that even if some elevators on the right are also designated as slightly lower temperature elevators, as long as the majority of right-side elevators still belong to the normal temperature elevator group, the ratio of the number of right-side elevators still belonging to the normal temperature elevator group to the number of right-side elevators belonging to the slightly lower temperature elevator group will not cause confusion for passengers regarding whether the left-side elevators are typically slightly lower temperature elevators or the right-side elevators are typically normal temperature elevators.

[0110] In addition, when the elevator call registration device and the elevator are relatively close (at least passengers can see the elevator information from the elevator call registration device), at least one of the elevator call registration device and the elevator must be present. When the elevator call registration device and the elevator are relatively far apart, the elevator call registration device must provide passengers with the instruction that the registered elevator call signal will be simultaneously assigned to the corresponding elevator group. This information can be displayed on the screen of the elevator call registration device, posted on relevant informational signs around the device where passengers can see it, or communicated to passengers via voice. When using an elevator or elevator lobby facility closer to the elevator call registration device for notification, appropriate signage in the waiting lobby can be used, such as different decorative styles, text, patterns, lighting, or displays on the left and right sides of the waiting lobby.

[0111] The following describes a preferred method for implementing notification:

[0112] The elevator group information corresponding to the elevator call signal registration device is set on the travel path from the building entrance to the elevator lobby or the elevator call signal registration device, and when the elevator group corresponding to the elevator call signal registration device changes, the providing module changes the elevator group information corresponding to the elevator call signal registration device.

[0113] For example, an identifier can be set up to indicate the elevator group information corresponding to the elevator call signal registration device. This identifier can be a sticker (which generally does not change), or it can be projected onto the appropriate location on the path floor by a projection device located in an appropriate position (such as the upper part of the lobby on the first floor). Passengers can understand the correspondence between the identifier and the corresponding elevator call signal registration device based on the location of the identifier. When the elevator group changes, the projection device can be notified in time and the corresponding projection identifier can be changed.

[0114] It should be noted that:

[0115] 1) The elevator call signal registration device mentioned above is essentially reused as a receiving device to receive information about the designated elevator group for passengers.

[0116] 2) The function of the notification mentioned above is to convey the correspondence between the elevator call signal registration device and the designated elevator group to the passengers, which is different from the notification module in Example 1 (which informs the correspondence between elevator groups and elevators, i.e., which elevator group a particular elevator belongs to).

[0117] Preferably, when providing passengers with optional elevator group information, the system also provides actual and predicted results of information related to different elevator groups, such as (estimated) waiting time and congestion levels, so that passengers can adjust their designated elevator group based on this information.

[0118] When providing elevator group information, the module also provides the actual results and predicted results for different elevator groups.

[0119] Example 6

[0120] This embodiment provides a detailed description of the notification module based on the aforementioned embodiments.

[0121] The notification module here is used to inform passengers of the elevator group information or response elevator information specified by the group-designated operation. Specifically, it provides passengers with information about the elevator they will be taking, mainly the elevator's identifier, the location information of the elevator group it belongs to, or information distinguishing the elevator group from other elevator groups. The notification method is usually in a way that passengers can perceive visually and / or audibly.

[0122] Example 7

[0123] This embodiment provides corresponding solutions for the following special cases based on the aforementioned embodiments.

[0124] Based on the example in Embodiment 2, assume the elevator layout plan is as follows: Figure 2 As shown in the diagram. Assume the elevators to be changed are elevator #4 and elevator #5. Elevator #5 meets both the technical feasibility requirements for elevator configuration and operational information, while elevator #4 does not meet the technical feasibility requirement for operational information (its travel time to the first-floor lobby is shorter than the time required to change the temperature inside the car). Considering that if elevator #5 is used as the elevator for group changes, after the group adjustment, the elevators in the normal temperature group will be divided into two non-adjacent parts by elevator #5, which is not conducive to passengers' identification of the normal temperature group elevators, it is decided to still use elevator #4 as the elevator for group changes, and the elevator group will be adjusted in real time only when the operational information of elevator #4 meets the change conditions (here, the travel time of the elevator from its current position to the first-floor lobby is longer than the time required to adjust the temperature inside its car).

[0125] In summary, when the proposed adjustment plan for the elevator group does not meet principle 1, the adjustment should be delayed; the elevator group adjustment should only be implemented when the operating information of the elevator to be changed meets the change conditions, so that the adjustment plan can meet principle 1.

[0126] Furthermore, when the basic information indicates that performing a group change operation on the elevators to be modified is not technically feasible, the grouping module sends a control command to the elevator system to alter the operating information of the elevators to be modified, thus making the group change operation technically feasible. An example scenario for this situation is as follows:

[0127] Elevator #4 departs from the 1st floor to transport passengers. Even if the car temperature is adjusted at this point, if the travel time required for Elevator #4 to transport passengers and return to the 1st floor is still shorter than the time required to adjust the car temperature, it is necessary to appropriately allocate call signals to Elevator #4 to ensure its operational information meets the change conditions. For example, call signals for destination floors farther from the 1st floor (e.g., the farthest) can be assigned to Elevator #4. This ensures that the travel time for Elevator #4 to return to the 1st floor is longer than the time required to adjust the car temperature, allowing for real-time elevator group adjustments. The advantage of this approach is that during weekday morning rush hours, passengers travel from the 1st floor to their respective destination floors, and as the elevator car ascends, the number of passengers in the car gradually decreases. This allows for real-time estimation of the travel time required for the elevator car to return to the 1st floor. By selecting a start time slightly longer than the time required to adjust the car temperature, the elevator car's air conditioning system can be controlled to begin adjusting the car temperature at that start time, ensuring the temperature is adjusted precisely when the elevator arrives at the 1st floor. Since passengers expect the car temperature to be the same as before the temperature adjustment when the elevator reaches the first floor, the temperature adjustment, starting at the initial moment, actually affects the passenger experience. Therefore, it is necessary to minimize the total passenger travel time during the temperature adjustment period. Given the passenger flow characteristics during weekday morning rush hour, the number of passengers decreases as the floor increases and there are no descending passengers. Therefore, selecting the elevator group adjustment start time using the above method can minimize the total passenger travel time during the temperature adjustment period.

[0128] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
