Description

Technical Field

[0001] The present invention relates to the technical field of elevators and robots, and in particular to a method in which an elevator replaces a robot to perform the broadcasting of voice broadcast content under certain conditions. Background Art

[0002] Robots riding elevators have become a research hotspot in the current elevator and robotics fields. Current research mainly focuses on the planning and navigation of the robot's movement path when the robot enters the elevator car from the landing station, the robot's movement within the car, and the robot's movement path when leaving the car and arriving at the landing station, as well as the setting of conditions for the robot to enter and exit the elevator car and the judgment of whether the conditions are met.

[0003] When entering or exiting an elevator car, or while inside it, the robot often makes voice announcements to receive the expected feedback corresponding to the announcement content. For example, when entering the car, if there is an obstructing passenger near the door, the robot will notify the obstructing passenger through voice announcement to avoid the obstructing passenger so that the robot can enter the car smoothly. In practice, after completing the voice announcement to the passenger, the robot often does not receive active cooperation and response from the passenger, resulting in the robot being unable to continue with subsequent specific actions, such as moving into the car and fully entering the car.

[0004] Therefore, how to improve passengers' cooperation and response to the robot's voice announcement has become a technical problem to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is how to improve passengers' cooperation and response to the robot's voice announcement.

[0006] In order to solve the above technical problems, the present invention discloses a voice broadcast control method, comprising:

[0007] Step S1, determining whether a specific event that the robot needs to announce to the outside world has occurred or a specific scene that the robot needs to announce to the outside world has occurred;

[0008] Step S2: When it is determined that a specific event or a specific scene has occurred, the robot or the elevator is determined to be the executor to perform the voice broadcast according to the specific event or specific scene;

[0009] Step S3: Control the executor to perform the voice broadcast.

[0010] Preferably, in step S2, the robot and the party in the elevator corresponding to the higher passenger confidence level are used as the executors of the voice announcement.

[0011] Preferably, when at least one of the following conditions is met, the voice announcement control method uses the elevator as the party corresponding to the high passenger confidence:

[0012] Condition 1: The first scope involved in a specific event or scenario exceeds the second scope around a single robot that people generally recognize;

[0013] Condition 2: The distance between the passenger and the robot involved in the voice broadcast exceeds the distance threshold;

[0014] Condition 3: The content of the voice announcement involves multiple robots, or the robots cooperate with passengers and / or elevators;

[0015] Condition 4: The voice broadcast content announced by the elevator is more authoritative than that announced by the robot.

[0016] Preferably, in step S2, the elevator is used as the executor of the voice announcement when a specific condition is met, and the specific condition includes at least one of the following conditions:

[0017] Condition A: The robot can only perform subsequent specific actions after the passenger receives the voice announcement and takes corresponding coordinated actions based on the content of the voice announcement;

[0018] Condition B requires passengers to pay special attention to the robot's subsequent specific actions.

[0019] Preferably, the specific conditions further include at least one of the following conditions:

[0020] Condition C: The elevator can only transport passengers after the robot completes the subsequent specific actions;

[0021] Condition D: The robot's subsequent specific actions will affect the passengers' elevator experience.

[0022] Preferably, step S2 determines the content to be broadcast according to the specific event or specific scene using the pre-established correspondence between the specific event or specific scene and the content of the voice broadcast, and performs judgment on condition 2, condition 3 and condition A according to the determined broadcast content.

[0023] Preferably, the method for judging whether condition D is met is: first, based on a specific event or a specific scene, determine the broadcast content that needs to be broadcast online, or use the pre-established correspondence between the specific event or specific scene and the broadcast content of the voice broadcast to determine the broadcast content that needs to be broadcast, and then complete the judgment of whether condition D is met based on the broadcast content.

[0024] Preferably, in step S2, after determining that a specific event or a specific scenario has occurred and the following conditions are met, it is determined whether the robot or the elevator will be the executor;

[0025] Condition 5: The robot's external voice announcement is for passengers who have or plan to take the elevator;

[0026] Condition 6: The robot's external voice broadcast location is inside the elevator car or elevator lobby.

[0027] Preferably, after the step S2 determines that the executor of the voice broadcast is the elevator, the step S3 controls the elevator to execute the voice broadcast while also notifying the robot to prohibit the execution of the voice broadcast.

[0028] Preferably, the notification content of notifying the robot to prohibit execution of the voice broadcast includes: the target robot as the notified object and the first broadcast content of the voice broadcast that is prohibited from execution.

[0029] Preferably, the notification content also includes: a resumption condition for the target robot to resume broadcasting the first broadcast content.

[0030] Preferably, the restoration conditions include: the end of the current specific event or specific scene, or the duration of the prohibited broadcast exceeds a time threshold, or the performer's voice broadcast of the broadcast content.

[0031] Preferably, in step S3, before controlling the executor to perform the voice announcement, the executor is determined to perform the voice announcement at the announcement time, and the executor is controlled to perform the voice announcement at the announcement time.

[0032] Preferably, when there is no ongoing voice broadcast in the elevator car (including the elevator and the robot), or when there is an ongoing voice broadcast in the elevator car and the ongoing voice broadcast can be interrupted, the current moment is used as the broadcast moment, and the executor is controlled to immediately execute the voice broadcast.

[0033] Preferably, when there is an ongoing uninterruptible voice broadcast in the elevator car, the priority of the ongoing uninterruptible voice broadcast is compared with the priority of the voice broadcast corresponding to a specific event or a specific scene, and when the priority of the latter is higher than the former, the broadcast of the former is terminated and the latter is broadcast; otherwise, the broadcast of the former is carried out until the broadcast of the former is completed and then the broadcast of the latter is carried out.

[0034] Beneficial technical effects

[0035] The present invention uses an elevator to replace a robot to perform voice announcements, thereby improving passengers' cooperation and response to the robot's voice announcements. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] none DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only embodiments of a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention. It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0038] Example 1

[0039] The entire process of a robot taking an elevator includes:

[0040] 1) After receiving the task and confirming that it needs to take the elevator, it moves from its current location to the elevator waiting point in the elevator lobby;

[0041] 2) After the elevator arrives and opens its door, the robot enters the elevator car from the waiting area and reaches the first point, which is the position inside the car near the elevator door when the robot just enters the car;

[0042] 3) moving from the first point to a predetermined final stopping position of the robot in the car;

[0043] 4) Before the elevator car reaches the destination floor, the robot moves from its final stop to the exit point, which is close to the elevator car door. The robot will exit the elevator car from this point after the elevator door opens.

[0044] 5) After the elevator car reaches the destination floor and the door opens, leave the elevator car at the exit point and enter the elevator lobby.

[0045] At each of the aforementioned stages, the robot may broadcast information to the outside world through voice broadcasts. For example, while the robot is inside the elevator car, it may provide passengers with information such as elevator riding tips and floor introductions. It may also ask passengers to cooperate when it needs to make way for the robot to complete its required movement. Some of these robot voice broadcasts are made outside the elevator car, while others are made inside the elevator car. Some require passengers to take corresponding actions based on the voice broadcast content (if specific conditions are met). Some do not require passengers to take any action but require them to pay special attention to the broadcast content and keep it in mind (such as the precautions broadcast by the robot in the event of a fire). Some simply provide some insignificant general information for passengers (such as weather and current affairs news, floor introductions, etc.).

[0046] Selectively broadcasting some of the robot's voice announcements through the elevator's voice system is conducive to improving passengers' cooperation and response to the robot's voice announcements.

[0047] To achieve the above objectives, this embodiment provides a voice broadcast control method, including:

[0048] Step S1, determining whether a specific event that the robot needs to announce to the outside world has occurred or a specific scene that the robot needs to announce to the outside world has occurred;

[0049] Step S2: When it is determined that a specific event or a specific scene has occurred, the robot or the elevator is determined to be the executor to perform the voice broadcast according to the specific event or specific scene;

[0050] Step S3: Control the executor to perform the voice broadcast.

[0051] The voice announcement control method of this embodiment is to select one of the elevator and the robot as the executor of the voice announcement. Obviously, not all voice announcements can be executed by both the elevator and the robot. Therefore, it is necessary to clarify the conditions that need to be met for the voice announcement to be executed by either the elevator or the robot.

[0052] We set conditions from the perspectives of the target passengers of the voice broadcast (i.e., to which passengers we want to provide the content of the voice broadcast) and the location of the voice broadcast (i.e., where the voice broadcast is made to the target passengers).

[0053] That is, in step S2, after determining that a specific event or a specific scenario has occurred and the following conditions are met, it is determined whether the robot or the elevator will be the executor;

[0054] Condition 5: The robot's external voice announcement is for passengers who have or plan to take the elevator;

[0055] Condition 6: The robot's external voice broadcast location is inside the elevator car or elevator lobby.

[0056] Obviously, after the above conditions are met, the problem of choosing one between the elevator and the robot as the executor of the voice broadcast has a basis for existence.

[0057] In this way, we can judge whether a specific event has occurred that requires the robot to make an external voice broadcast or a specific scene has occurred at each stage of the robot's elevator riding process; when it is determined that a specific event has occurred or a specific scene has occurred, we can further judge whether the specific event or specific scene meets the above conditions. When the above conditions are met, we will decide which one of the robot and the elevator will serve as the executor of the voice broadcast for the specific event and specific scene, and control the executor to perform the voice broadcast.

[0058] Example 2

[0059] Based on the first embodiment, this embodiment further defines and explains how to determine which of the robot and the elevator is to be the executor of the voice announcement.

[0060] As mentioned above, we choose between a robot and an elevator as the executor of the voice announcement. Therefore, we only need to determine under what circumstances the elevator will be selected as the executor of the voice announcement, because in other cases the robot must be selected as the executor of the voice announcement.

[0061] Theoretically, whether a robot or an elevator performs voice announcements, as long as the announcements are received by the intended passengers, the purpose and effectiveness of the announcements can be achieved. However, for some announcements, the effect is significantly better when the elevator performs them than when the robot performs them. For other announcements, the effect is almost the same whether the elevator or the robot performs them.

[0062] First, we need to analyze the purpose of voice announcements, that is, what information is provided to passengers through the content of voice announcements, and what effect we hope to achieve through voice announcements.

[0063] As can be seen from the description in Example 1, some robot announcements simply provide general, irrelevant information for passengers (such as weather, current events, and floor introductions), while others strongly encourage passengers to receive and understand the content of the announcement, and to act accordingly or pay sufficient attention. Therefore, we divide the announcements into two categories: the first category is announcements that provide general, irrelevant information, and the second category is announcements that strongly encourage passengers to receive, act accordingly, or pay sufficient attention.

[0064] For the first type of voice announcement, there is not much difference in the expected effect of the voice announcement between choosing an elevator or a robot as the performer, so either elevator or robot can be chosen as the performer. For the second type of voice announcement, it is hoped that by appropriately selecting the performer, the expected effect of the voice announcement can be better achieved. Specifically, when the voice announcement meets certain conditions, it is classified as the second type of voice announcement; otherwise, it is classified as the first type of voice announcement, where the certain conditions include at least one of the following conditions:

[0065] Condition A: The robot can only perform subsequent specific actions after the passenger receives the voice announcement and takes corresponding coordinated actions based on the content of the voice announcement;

[0066] Condition B requires passengers to pay special attention to the robot's subsequent specific actions.

[0067] In addition, the specific conditions may further include at least one of the following conditions:

[0068] Condition C: The elevator can only transport passengers after the robot completes the subsequent specific actions;

[0069] Condition D: The robot's subsequent specific actions will affect the passengers' elevator experience.

[0070] Among them, for condition D, first determine it online based on a specific event or specific scene, or use the pre-established correspondence between the specific event or specific scene and the voice broadcast content to determine the broadcast content that needs to be broadcast, and then complete the judgment of whether condition D is met based on the broadcast content.

[0071] In addition, step S2 determines the content of the announcement that needs to be announced based on the specific event or specific scene, using the pre-established correspondence between the specific event or specific scene and the announcement content of the voice announcement, and performs the judgment of condition A and the conditions involved in methods 3, 4 and 5 below based on the determined announcement content.

[0072] The following is the reason why the voice broadcast effects are different when a robot is used as the executor of the voice broadcast and when an elevator is used as the executor of the voice broadcast (usually the elevator as the executor is better than the robot as the executor). That is, the basis for selecting the elevator as the executor of the voice broadcast to meet the second type of voice broadcast’s demand for broadcast effects, or the basis for selecting the elevator as the executor of the voice broadcast as a technical means to solve the technical problem of the second type of voice broadcast’s high demand for broadcast effects.

[0073] First, since the second type of voice broadcast meets at least one of conditions A and B, or also meets at least one of conditions C and D, the higher the degree of acceptance of the content of the voice broadcast by the target passengers (an indicator used to measure the degree of trust and adoption of the content of the voice broadcast by passengers), the higher the possibility that the target passengers will respond to the content of the broadcast, take cooperative actions, and pay enough attention, and the better the effect that the voice broadcast can achieve.

[0074] Methods for selecting the performer of the voice announcement from the elevator and the robot include but are not limited to the following methods:

[0075] Method 1: Determine the voice announcement performer based on the passenger's confidence in the announcement content. Specifically, the robot or elevator with the highest passenger confidence is assigned as the voice announcement performer. So, under what circumstances would the target passenger's confidence in the announcement made by the elevator be higher than that made by the robot? The following example scenario involves a specific event or scenario involving a first range that exceeds the conventionally perceived second range surrounding a single robot.

[0076] Generally, people believe that a robot's voice announcement is targeted at passengers within a second range near the robot. Therefore, when the first range of the specific event or scenario that necessitates the robot's voice announcement to the target passengers significantly exceeds the second range, that is, when some or all of the target passengers for the robot's voice announcement, as determined by the specific event or scenario, are outside the second range, the target passengers outside the second range will inevitably become suspicious of the robot's voice announcement (and its content). Understandably, in this case, the target passengers' confidence in the robot's announcement will be low. However, when the elevator is the executor of the voice announcement, since it is intended for all passengers, the elevator's range in people's minds is inevitably much larger than the robot's second range. Therefore, when the first range exceeds the second range, the target passengers' confidence in the announcement when the elevator is the executor is inevitably higher than when the robot is the executor. Therefore, the elevator should be considered the executor of the voice announcement.

[0077] Method 2: The executor of the voice broadcast is determined based on the authority of the robot and the elevator, that is, the one with higher authority between the robot and the elevator is used as the executor of the voice broadcast.

[0078] In the five stages of the robot's elevator riding process in Example 1, except for the first stage (i.e., the robot moves from its current position to the elevator waiting point), the other four stages are closely related to the elevator car, and are basically all or partially located in the elevator car. Since these stages involve both the robot and the elevator (car), it is unnecessary and unreasonable for the elevator and the robot to perform voice broadcasts of the same content at the same time. Therefore, one of the elevator and the robot should be selected to represent the two to perform voice broadcasts. Then, this embodiment proposes to use the party with higher authority as the executor of the voice broadcast. Compared with the robot, the elevator has higher authority, so the elevator should be selected as the executor of the voice broadcast. The reason is:

[0079] 1) When a robot rides an elevator, the elevator picks it up at its departure floor and transports it to its destination floor. This means the elevator provides transportation services for the robot. Therefore, the elevator is the service provider, and the robot is the service recipient. The elevator is the primary party in the robot's ride, while the robot is a secondary party. Therefore, the elevator, as the service provider, naturally holds greater authority.

[0080] 2) The vast majority of robot elevator rides occur near or within the elevator car, and the robot is located within it. This means the robot is contained within the elevator car. The elevator car, as the container, has larger dimensions, while the robot, as the container, has smaller dimensions. Therefore, the elevator car has a much greater visual impact on passengers than the robot. As psychological theory suggests, people tend to interpret larger objects as more important and authoritative, moving from the concrete to the abstract. Therefore, the elevator has a higher degree of authority than the robot.

[0081] Method 3: The executor of the voice announcement is determined based on the distance between the passenger to be announced and the robot. That is, when the distance between the passenger to be announced and the robot exceeds the distance threshold, the elevator is used as the executor of the voice announcement.

[0082] People generally assume that a robot's voice announcements are targeted at passengers near the robot, while passengers farther away may subconsciously assume the announcements are irrelevant to them. Furthermore, when the robot's target passengers are too far away, the robot's voice announcements are limited in range and passengers far away may not be able to hear the announcements clearly or even be completely unaware that the robot is making them. Therefore, when the robot's target passengers are too far away from the robot, the announcements are not ideal. However, using an elevator to perform the announcements instead of the robot overcomes these shortcomings, as the elevator's announcements are directed to all passengers in the cabin, resulting in better announcements.

[0083] Method 4: The executor of the voice broadcast is determined according to the number of robots that need to perform voice broadcast (of the same voice broadcast content). That is, when there are multiple robots that need to perform voice broadcast for the same voice broadcast content at the same time, the elevator is used as the executor of the voice broadcast.

[0084] When there are multiple robots that need to simultaneously broadcast the same announcement, for example, at a certain moment, a first robot is passing through an elevator door to board a car, but a passenger is blocking its path and requires its cooperation. Another robot, which entered the car earlier, is moving toward its docking location, but another passenger is blocking its path and requires its cooperation. Obviously, both robots need to broadcast an announcement reminding passengers to take evasive action. If the two robots are allowed to broadcast independently, there will inevitably be a certain time difference between the two robots' announcements. Therefore, even if the announcements are the same, they will interfere with each other, making it difficult for passengers to hear the announcements, thus failing to achieve a good announcement effect. If the robots that need to broadcast announcements are coordinated and only one of them broadcasts, people will also assume that the robot's announcement is limited to its surrounding area. Passengers around the robot that is not broadcasting will believe that the announcement is irrelevant to them, thus failing to achieve a good announcement effect. At this time, the elevator needs to be used as the executor of the voice broadcast. Since the sound of the elevator's voice broadcast can cover all areas in the car, and people usually think that the elevator's voice broadcast is related to every passenger in the car and requires passengers to pay enough attention, therefore, compared with the robot as the executor, the elevator as the executor of the voice broadcast at this time can achieve better voice broadcast effects.

[0085] Method 5: The executor of the voice announcement is determined based on whether the robot needs to cooperate with multiple passengers or whether there are multiple specific passengers (a specific passenger is a passenger whose cooperation will enable the robot to perform subsequent specific actions). That is, when the robot needs multiple passengers to cooperate with each other or there are multiple specific passengers, the elevator will be used as the executor of the voice announcement.

[0086] When a robot is riding an elevator, scenarios often arise where the robot requires the coordinated actions of multiple passengers to complete its subsequent specific actions (i.e., if any passenger fails to cooperate, the robot cannot complete its subsequent specific action). Alternatively, if multiple passengers fail to cooperate due to the bystander effect, the robot cannot complete its subsequent specific action. The bystander effect, also known as the diffusion of responsibility effect, refers to the fact that when a single individual is asked to complete a task, they have a strong sense of responsibility and respond positively. However, when a group is asked to complete a task together, each individual in the group has a weak sense of responsibility and tends to retreat when faced with difficulties or responsibilities. This is because the former assumes responsibility independently, while the latter expects others to shoulder more responsibility. The essence of "diffusion of responsibility" is that many people are irresponsible and accountability is not implemented. Factors that contribute to the bystander effect include social inhibition, social influence, majority neglect, and diffusion of responsibility. To ensure that the robot is not unable to complete its subsequent specific actions due to passenger non-cooperation in these scenarios, it is necessary to encourage passenger cooperation. To increase passengers' enthusiasm for cooperation, they must be made aware that the content of the voice announcement is relevant to them and that they have a responsibility and obligation to cooperate, thus avoiding the bystander effect. To ensure that passengers recognize their responsibility to cooperate, the elevator can be the executor of the voice announcement, with all passengers in the car as the target passengers. The elevator can make the announcement to all passengers in the car, making each passenger aware of their responsibility and obligation to cooperate. In this case, the elevator should be the executor of the voice announcement.

[0087] Example 3

[0088] In the voice broadcast control method of this embodiment, after determining in step S2 that the executor of the voice broadcast is the elevator, step S3 controls the elevator to execute the voice broadcast while also notifying the robot to prohibit the execution of the voice broadcast.

[0089] The notification content of notifying the robot to prohibit the execution of the voice broadcast includes: the target robot as the notified object and the first broadcast content of the voice broadcast to be prohibited. The purpose is to avoid the elevator and the robot simultaneously making the same voice broadcast content.

[0090] The notification also includes the conditions for the target robot to resume broadcasting the first broadcast content. The resumption conditions include: the end of the specific event or specific scene, or the duration of the prohibited broadcast exceeding the time threshold, or the performer's voice broadcast of the broadcast content.

[0091] Example 4

[0092] In the voice announcement control method of this embodiment, step S3 determines the announcement time for executing the voice announcement before controlling the executor to execute the voice announcement, and controls the executor to execute the voice announcement at the announcement time.

[0093] When there is no ongoing voice broadcast in the elevator car (including the elevator and the robot), or when there is an ongoing voice broadcast in the elevator car and the ongoing voice broadcast can be interrupted, the voice broadcast control method uses the current moment as the broadcast moment and controls the executor to immediately execute the voice broadcast.

[0094] When there is an ongoing uninterruptible voice broadcast in the elevator car, the priority of the ongoing uninterruptible voice broadcast is compared with the voice broadcast corresponding to a specific event or a specific scene. When the priority of the latter is higher than the former, the broadcast of the former is terminated and the latter is broadcast. Otherwise, the broadcast of the former is carried out until the broadcast of the former is completed and then the broadcast of the latter is carried out.
