[0002] Elevators are capable of providing a variety of personalized services, such as adjusting the car's air conditioning temperature and lighting intensity. Currently, these capabilities are typically controlled by property management personnel, or require passengers to pre-install a dedicated app on their mobile devices, using communication between the mobile device and the elevator to adjust these personalized services.

[0004] Therefore, how to determine whether a passenger has the willingness to adjust personalized services and how to provide passengers with the means to realize personalized services after such determination has become a technical problem to be solved. Summary of the Invention

[0018] Preferably, step S1 obtains the current value of the parameters of the service item and uses the current value of the parameters of the service item as the current status of the service item.

[0019] Preferably, step S4 determines the parameter value corresponding to the passenger's expectation based on the pre-established preference-parameter correspondence, calculates the difference between the current value of the parameter and the expected parameter value, takes the maximum value of the difference as the range, divides the range into several intervals, and each interval corresponds to a willingness level.

[0020] Preferably, when the willingness level exceeds a threshold, step S5 determines to provide passengers with a means to change the status quo of the service.

[0021] Preferably, the passenger information is the passenger's identity information, and step S3 determines the passenger's preference for the service item configuration parameters based on the passenger's identity information and using the pre-stored identity-item-preference correspondence.

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.

[0034] Example 1

[0035] like Figure 1 As shown, this embodiment provides a method for providing operating means to elevator passengers, including:

[0036] Step S1: Determine the current status of the services provided to elevator passengers;

[0037] Step S2: Obtain passenger information;

[0038] Step S3: Calculate the passenger's preference for the service based on the passenger information;

[0039] Step S4: Determine the difference between the current status of the service and the passenger's preferences, and determine the passenger's willingness to change the current status of the service based on the difference;

[0040] Step S5: Based on the passenger's stated wishes, decide whether to provide the passenger with the means to change the current status of the service.

[0041] The service items satisfy the following:

[0042] Condition 1: The service items can be subjectively perceived by passengers;

[0043] Condition 2: For each service item, there are at least two different passenger preferences.

[0044] In addition to the two conditions mentioned above, preferably, the service items may further satisfy the following:

[0045] Condition 3: The current status of the service item can be described by the corresponding parameters;

[0046] Condition 4: Passengers' preferences for the services correspond to the parameters.

[0047] Condition 5: Passengers can change the status of the service by changing the parameter values ​​of the service.

[0048] The operating method refers to the input method by which passengers input the parameters into the elevator. This includes voice input, text input, gesture input, and scanning and recognition devices used to scan and identify objects provided by passengers (such as graphics, QR codes, strings, etc., containing the passenger's desired parameter values), etc.

[0049] Here, "service items" refers to the services provided by the elevator that passengers can subjectively perceive and directly experience during their elevator ride. Examples include the temperature and illuminance inside the elevator car. Temperature and illuminance, as service content and objectives, are continuous physical quantities with a certain range of values, and can obviously be described using the parameters temperature and illuminance. In addition, the elevator call signal registration device, besides the floor registration device (up / down buttons or destination floor registration device), can also be considered a service item satisfying conditions 1 to 3. This is because passengers will inevitably perceive the call signal registration device when performing the destination signal registration operation, and its parameters can correspond to the presence or absence of the call signal registration device—that is, whether the elevator provides the call signal registration device for passengers. In this case, the parameters only include two values: yes or no. Therefore, the temperature and illuminance inside the elevator car, as well as the elevator call signal registration device (excluding the floor registration device, up / down buttons or destination floor registration device), can all be considered as the aforementioned service items. However, vibration and noise of the elevator car during movement are generally not considered to be services that meet the above conditions, because passengers generally have difficulty having a very intuitive and direct feeling about vibration and noise while riding the elevator, especially when the vibration and noise are so small that passengers can hardly perceive them.

[0050] Different passengers may have different preferences for the temperature inside the car. Possible preferences include: very cool, generally cool, comfortable, slightly warm, and warm. The corresponding temperature ranges (i.e., parameter values) in public places in summer are: below 20°C, 22°-23°C, 23°-24°C, 24°-25°C, and 25°-26°C, respectively. Obviously, passengers can change the actual temperature inside the car by changing the set value of the car's air conditioning temperature, so that the actual temperature inside the car is close to the temperature corresponding to the passenger's preference.

[0051] Therefore, the car temperature meets all the aforementioned conditions, and can thus be used as an example of a service item.

[0052] Example 2

[0053] This embodiment is based on Embodiment 1, and the steps therein are described in detail.

[0054] Step S1 obtains the current value of the parameters of the service item, and determines the current status of the service item based on the obtained current value of the parameters of the service item.

[0055] Step S1 uses a pre-established parameter range-passenger preference relationship table to determine the current passenger preference status corresponding to the current status of the service item based on the range in which the current value of the service item's parameter is located.

[0056] The passenger preferences are ordered according to their corresponding parameter ranges (e.g., according to temperature from low to high, the preference order is: very cool, generally cool, suitable, slightly warm, warm, and the corresponding temperature ranges in public places in summer are: below 20°, 22°-23°, 23°-24°, 24°-25°, and 25°-26°). The difference refers to the interval between the current order of passenger preferences corresponding to the current status of the service item and the passenger's preference order for the service item.

[0057] The relationship between the intention and the difference is monotonically increasing, that is, the greater the difference, the stronger the intention (the intention can be divided into several levels, and each level corresponds to a difference).

[0058] Specifically, regarding the example of the elevator car's interior temperature, step S1 obtains the current temperature value inside the car (assuming the current value is 24.5°C) from the elevator control system (or directly from the car's air conditioning system, temperature sensors inside the car, etc.) and determines the current state of the car's interior temperature based on this value. Here, "current state" refers to which passenger preference the actual temperature value corresponds to. Since the current value of 24.5°C falls between 24°C and 25°C, corresponding to the preference for slightly warmer temperatures, the current state of the elevator car's interior temperature is "slightly warm."

[0059] Step S2, obtaining passenger information of elevator passengers, and step S3, calculating the elevator passengers' preferences for the service items based on the passenger information, include the following two scenarios:

[0060] Scenario 1: The passenger information obtained in step S2 is the passenger's identity information. Step S3 determines the passenger's preference for the service item configuration parameters based on the passenger's identity information and using the pre-stored identity-item-preference correspondence. For example, if the obtained passenger identity information is: Passenger A, and one of the identity-item-preference correspondences is: Passenger A - Car Interior Temperature - Suitable, then it can be determined that the passenger's preference for the car interior temperature service item is suitable.

[0061] Scenario 2: The passenger information obtained in step S2 is an external attribute that can be detected visually (or obtained by taking images with a camera and processing them through image recognition), such as the passenger's gender, age, clothing, and items carried (such as fans, towels, portable fans, etc.); step S3 at least infers the elevator passenger's preference for the service based on these external attributes.

[0062] For example, in the sweltering summer, young passengers often prefer a generally cool temperature. However, if they further fan themselves or wipe their sweat with a handkerchief (or wear light summer clothing), their preference may shift to a particularly cool temperature. Elderly passengers, on the other hand, might prefer a slightly warmer or warmer temperature. By analyzing the factors influencing passenger preferences for cabin temperature and pre-establishing the correspondence or inference rules between these factors and preferences, the actual values ​​of the influencing factors can be obtained through image recognition. Based on these values, the corresponding passenger preferences can then be derived using the correspondence or inference rules between the influencing factors and preferences.

[0063] Step S4 determines the difference between the current status of the service (represented by the preference corresponding to the temperature inside the elevator car) and the preferences of elevator passengers, and determines the elevator passengers' willingness to change the current status of the service based on the difference. Since passenger preferences have a certain order, the difference between the current status of the service and the order of the elevator passengers' preferences can be used to represent the difference between the current status of the service and the elevator passengers' preferences. For example, when the actual temperature inside the elevator car is 24.5°C—that is, the current temperature inside the elevator car is "slightly warm"—and the elevator passengers' preference is "generally cool," since the order of "generally cool" is 2 and the order of "slightly warm" is 4, the difference between the two is 2. The elevator passengers' willingness to change the current status of the service is pre-divided into n levels (n is the number of preferences), so the aforementioned "difference" corresponds to the willingness level. For example, if the difference is 2 in the previous example, then the willingness level is 2.

[0064] When the level of willingness exceeds a threshold, step S5 determines to provide passengers with a means to change the current status of the service. For example, a rule is pre-established—when the level is ≥2, the elevator passenger is provided with a means to change the current status of the service. According to this rule, in the previous example, the elevator passenger would be provided with a means to change the current status of the service.

[0065] Example 3

[0066] This embodiment is based on Embodiment 1, and the steps therein are described in detail.

[0067] In this embodiment, step S1 obtains the current value of the parameters of the service item and uses the current value of the parameters of the service item as the current status of the service item.

[0068] Steps S2 and S3 are the same as in Example 2.

[0069] Step S4 determines the parameter value corresponding to the passenger's preference based on the pre-established preference-parameter correspondence (considering it is a parameter range, the median value of the range can be used as the expected parameter value), and calculates the difference between the current value of the parameter and the expected parameter value (i.e., the difference). There are two processing methods following this:

[0070] Method 1: The maximum value of the difference is used as the range, and this range is divided into several intervals (each interval has a preference order similar to that in Example 2 based on the size of the difference it covers), and each interval corresponds to a willingness level. After obtaining the aforementioned difference, the corresponding willingness level is determined according to the order in which the difference falls into the interval (e.g., the order number is used as the willingness level). Step S5 uses the method in Example 2 to determine whether to provide elevator passengers with a means to change the current status of the service item;

[0071] Method 2: Considering that there are only two possible outcomes determined in step S5, a threshold is directly given. When the difference exceeds this threshold, a means to change the status quo of the service item is provided to the elevator passengers; otherwise, no means to change the status quo of the service item are provided to the elevator passengers. Compared to Method 1, this method is simpler and easier to implement.

[0072] Example 4

[0073] In the foregoing embodiments, the means of changing the status quo of the service item refers to the input method of passengers providing parameters corresponding to their preferences to the elevator. The following mainly describes the processing after step S5 determines to provide elevator passengers with the means to change the status quo of the service item.

[0074] When step S5 decides to provide the passenger with a means to change the status quo of the service item, the passenger is informed that a means to change the status quo of the service item has been provided if any of the following conditions are met: Condition 1: The distance between the means provided to the passenger for changing the status quo of the service item and the passenger allows the passenger to immediately carry out the change operation; Condition 2: The location of the means is appropriately changed to reduce the distance between the means and the passenger so that the passenger can immediately carry out the change operation.

[0075] The notification can take any form that passengers can receive—primarily through visual or auditory means. For example, it could be displayed as text or animation informing passengers that a means to change the current service is available, or it could be announced via voice. Step S6 determines the notification content based on the passenger's location. For instance, for a passenger on a floor (i.e., not yet in the elevator), they can be informed that they can input their desired elevator temperature parameter value (e.g., via touch or voice), and can also input their preferred temperature (e.g., "I want the elevator temperature to be comfortable"). For a passenger already in the elevator, the notification could be, "I want the elevator temperature to be lower." Clearly, input methods include voice input and / or an input interface for passengers to input desired parameter values.

[0076] This embodiment does not limit the entity that performs the notification, such as a floor display screen, a floor voice broadcasting device, a car display screen, or a car voice broadcasting device; similarly, it does not limit the input means provided to passengers, such as a device on the floor or inside the car that allows passengers to perform input operations (such as a touch screen that needs to display a certain input interface, a voice input device, etc.).

[0077] Of course, it could also be a robot as described in the following embodiments.

[0078] Example 5

[0079] In this embodiment, after determining the means to provide passengers with a change in the status quo of the service item, step S5 involves the control robot providing the input method to the passengers.

[0080] Step S5 selects a robot from among those robots capable of providing the input path to the passenger, based on the passenger's location where the input path is provided.

[0081] One way to select the robot in step S5 is as follows:

[0082] Step A1: Determine the timing for providing the input method to passengers based on the service items;

[0083] Step A2: Determine the time interval from the current moment to the time when the opportunity is provided;

[0084] Step A3: Determine the current location of each candidate robot capable of providing the input method to passengers;

[0085] Step A4: Estimate the travel time required for the candidate robot to move from its current position to the passenger position where the input path is provided;

[0086] Step A5: Select the candidate robot whose movement time is less than the time interval as the selected robot.

[0087] Another way to select the robot in step S5 is as follows:

[0088] Step B1: Determine the current location of each candidate robot capable of providing the input pathway to passengers;

[0089] Step B2: Determine whether there is at least one robot whose distance to the informed passenger meets the requirements (i.e., the passenger can perform the input operation). If so, select the robot and end the process; otherwise, proceed to the next step.

[0090] Step B3: Determine the timing for providing the input method to passengers based on the service items;

[0091] Step B4: Determine the time interval from the current moment to the time when the opportunity is provided;

[0092] Step B5: Estimate the travel time required for the candidate robot to move from its current position to the passenger position where the input path is provided;

[0093] Step B6: Select the candidate robot whose movement time is less than the time interval as the selected robot.

[0094] When multiple candidate robots exist, the selected robot shall be chosen according to at least one of the following principles:

[0095] Principle 1: Be closest to the informed passenger;

[0096] Principle 2: Minimize the number of unfinished tasks;

[0097] Principle 3: Unfinished tasks have the lowest urgency value;

[0098] Principle 4: Passengers on the same destination level as those who have been informed.

[0099] Principle 5: The response elevator should be the same as the one that informed the passenger.

[0100] Principles 4 and 5 can meet the input requirements of passengers waiting for the elevator to enter the elevator car.

[0101] 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.
