Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to an animal-based door control method, device, equipment and storage medium. Background Art

[0002] With the development of urbanization, high-rise buildings such as residential buildings, office buildings, and teaching buildings have become widely popular, and elevators have become an important means of transportation in people's lives, studies, and work.

[0003] At present, many users keep cats, dogs and other pets in their homes, so it is common for users to take elevators with their pets.

[0004] Some elevators have posted notices inside the car and lobby to remind users to take good care of their pets. However, when the elevator door is open, the pet's attention is attracted, and it is easy for the pet to escape the user's supervision and enter and exit the elevator on its own, separating the user from the pet, posing a danger to the pet and surrounding users. Summary of the Invention

[0005] The present invention provides an animal-based door control method, device, equipment and storage medium to solve the problem of how to improve the safety of users carrying animals in elevators.

[0006] According to one aspect of the present invention, there is provided an animal-based door control method, comprising:

[0007] Selecting a target elevator from a plurality of elevators, wherein the target elevator is an elevator whose car is parked at a certain floor, and the floor has an elevator lobby for the plurality of elevators;

[0008] identifying a dangerous area in the elevator lobby before the target elevator;

[0009] detecting animals in the danger zone and the cabin of the target elevator respectively to obtain a first detection result;

[0010] Detecting passengers in the elevator lobby and the elevator car of the target elevator respectively to obtain a second detection result;

[0011] The door of the car of the target elevator is controlled according to the first detection result and the second detection result.

[0012] According to another aspect of the present invention, there is provided an animal-based door control device comprising:

[0013] A target elevator selection module is used to select a target elevator from multiple elevators, wherein the target elevator is an elevator whose car is parked at a certain floor, and the floor is provided with an elevator lobby for multiple elevators;

[0014] a dangerous area identification module, configured to identify a dangerous area in front of the target elevator in the elevator lobby;

[0015] an animal detection module, configured to detect animals in the dangerous area and the car of the target elevator, respectively, and obtain a first detection result;

[0016] a passenger detection module, configured to detect passengers in the elevator lobby and the elevator car of the target elevator, respectively, to obtain a second detection result;

[0017] A door control module is used to control the door of the elevator car of the target elevator according to the first detection result and the second detection result.

[0018] According to another aspect of the present invention, an electronic device is provided, comprising:

[0019] at least one processor; and

[0020] a memory communicatively connected to the at least one processor; wherein,

[0021] The memory stores a computer program executable by the at least one processor, and the computer program is executed by the at least one processor to enable the at least one processor to perform the animal-based door control method according to any embodiment of the present invention.

[0022] According to another aspect of the present invention, a computer-readable storage medium is provided, wherein the computer-readable storage medium stores a computer program, and the computer program is configured to enable a processor to implement the animal-based door control method according to any embodiment of the present invention when executed.

[0023] In this embodiment, a target elevator is selected from multiple elevators. The target elevator is an elevator with a car parked at a floor, and a lobby is provided for each floor. A dangerous area is identified in the lobby before the target elevator. Animals are detected in the dangerous area and in the car of the target elevator, respectively, to obtain a first detection result. Passengers are detected in the lobby and in the car of the target elevator, respectively, to obtain a second detection result. The door of the car of the target elevator is controlled based on the first and second detection results. The dangerous area before the elevator car can identify the tendency of animals to enter the car in the dangerous area. By combining the presence of animals in the dangerous area, animals in the car, passengers in the lobby, and passengers in the car, the relationship between the target elevator and the animals when the target elevator is parked at the floor can be determined to a certain extent. Based on the different relationships, the door of the car of the target elevator is adaptively controlled, which increases the flexibility of the car door control and makes it more closely aligned with the actual situation. This reduces the separation between users and their pet animals and reduces the contact between users and non-pet animals when riding the elevator, thereby improving the safety of users and animals when riding the elevator.

[0035] Example 1

[0036] Figure 1 This is a flowchart of an animal-based door control method provided in Example 1 of the present invention. This embodiment is applicable to the situation where the door of the elevator car is controlled based on the distribution information of passengers, animals in the elevator lobby (including the dangerous area in front of the elevator car door), and the elevator car. The method can be executed by an animal-based door control device, which can be implemented in the form of hardware and / or software. The animal-based door control device can be configured in an electronic device, especially an elevator control system and / or an elevator edge computing node. Figure 1 As shown, the method includes:

[0037] Step 101: Select a target elevator from multiple elevators.

[0038] Generally speaking, elevators have different types and functions, such as passenger elevators, freight elevators, sightseeing elevators, etc. Therefore, the components installed in the elevators are also different.

[0039] In one example, the components of a certain type of elevator include a traction machine, a control cabinet, a speed limiter, a door opener, a car frame, a car door, a counterweight guide rail, a car guide rail, a guide rail support, a traveling cable, a counterweight device, a compensating chain (cable), a landing door, a guide device for the compensating chain (cable), and a buffer.

[0040] Of course, in some types of elevators, the traction machine, control cabinet, speed limiter, and accompanying cable can be omitted, and this embodiment does not limit this.

[0041] like Figure 2 As shown, a control system 210 and multiple elevators 230 may be deployed in a building, and the control system 210 has logic for controlling the operation of each elevator 230 .

[0042] Generally, the controller is a microprocessor unit (MPU) with weak computing power. Therefore, the elevator manager or owner can choose whether to install an edge computing node on the elevator near the elevator control system in the building according to needs.

[0043] If you choose not to install an edge computing node, the elevator control system maintains the original control logic and does not affect the normal operation of the elevator.

[0044] If you choose to install an edge computing node, Figure 2 As shown, the edge computing node 220 of the elevator is connected to the control system 210 of the elevator. The control system 210 of the elevator and the edge computing node 220 of the elevator can be connected using a serial port (such as RS485) or a network, and the logic of the elevator control system 210 and the edge computing node 220 of the elevator to control the operation of the elevator is redefined.

[0045] Among them, the edge computing node is a computing device with strong computing power, which can be a computer, server or embedded device. In addition, the edge computing node can be equipped with a graphics processing unit (GPU) or an embedded neural network processor (NPU) according to needs.

[0046] like Figure 2-Figure 5 As shown, each floor in the building can be provided with an elevator lobby 300 for multiple elevators 230, i.e., a place where passengers wait for the elevator. In some design specifications, the depth of the elevator lobby should not be less than the depth of the largest elevator car among the multiple elevators, and should not be less than 1.5 meters.

[0047] In addition, if Figure 2-Figure 5 As shown, a first camera 301 and a first speaker 302 can be installed at a position such as above the elevator lobby 300. The visual range of the first camera 301 covers the elevator lobby 300, so that the first camera 301 can capture the doors of all elevator cars in the elevator lobby 300.

[0048] In the car 231 of each elevator 230, a second camera 232 and a second speaker 233 can be installed at a position such as the center above the inner wall of the car 231, and a sound wave generator 234 can be installed at a position such as the inner wall of the car 231. The visual range of the second camera 232 covers the car 231. When the door of the car 231 is open, the visual range of the second camera 232 covers the area in front of the door of the car 231 and part of the elevator lobby 300.

[0049] The first camera 301 and each second camera 232 can be connected to the elevator's edge computing node 220 via a serial port or a network, and the elevator's edge computing node 220 processes the image data collected by the first camera 301 and each second camera 232.

[0050] The first speaker 302, each second speaker 233 and the sound wave generator 234 can be connected to the elevator control system 210 via a serial port or a network, and the elevator control system 210 controls the first speaker 302, each second speaker 233 and the sound wave generator 234 to operate.

[0051] There are multiple hoistways inside or outside the building. The cars of each elevator move (i.e., slide) in the hoistways. A control panel is set on each floor or the first floor of the building. The control panel generally has buttons for calling the elevator up and down. Passengers can press these buttons to issue an elevator call request (i.e., an elevator call).

[0052] Of course, in addition to the control panel, passengers can also use the client, remote control, etc. to issue elevator call requests, and this embodiment does not limit this.

[0053] When an elevator receives a call (i.e., an external call), it controls the car to slide in the shaft to the passenger's floor, opens the door, and closes the door after the passenger enters the car. A control panel is set up in the car, which generally has buttons for each floor, door opening, door closing, alarm, etc. Passengers can press the buttons for each floor to make an elevator request (i.e., an internal call).

[0054] Of course, in addition to the control panel, passengers can also use the client, remote control, etc. to issue elevator requests, and this embodiment does not limit this.

[0055] When an elevator receives a request to board the elevator (i.e., an internal call), it controls the car to slide in the hoistway to the destination floor indicated by the passenger, opens the car door, and closes the car door after the passenger exits the car.

[0056] When multiple elevators are moving due to internal calls and / or external calls, one of the elevators can be selected as a target elevator, wherein the target elevator is an elevator with a car parked at a certain floor. At this time, the elevator is waiting at the floor for the control door to open and / or close.

[0057] Step 102: Identify a dangerous area in front of a target elevator in the elevator lobby.

[0058] When the target elevator stops at the current elevator lobby, an area in front of the target elevator can be identified in the elevator lobby. This area is close to the door of the target elevator car. Since there is a risk of animals escaping from the supervision of passengers and entering the target elevator on their own, this area can be recorded as a dangerous area.

[0059] In one embodiment of the present invention, step 102 may include the following steps:

[0060] Step 1021: Call the first camera to collect first image data facing the elevator lobby.

[0061] like Figure 2 、 Figure 4 and Figure 5 As shown, the first camera 301 is installed in the elevator lobby 300. When the target elevator stops at the current elevator lobby 300, the first camera 301 can be called to face the elevator lobby 300 to collect first image data.

[0062] Step 1022: Determine the visible range in the elevator lobby when looking from the elevator car of the target elevator toward the elevator lobby.

[0063] Step 1023: Mark the visible range in the first image data as a dangerous area.

[0064] In this embodiment, the door of the target elevator car can be dynamically controlled based on whether there are animals in the dangerous area and the target elevator car, and whether there are passengers in the elevator lobby and the target elevator car. At this time, the logic of controlling the door of the target elevator car may be different from the conventional logic of controlling the door of the target elevator car.

[0065] In order to enable the passengers in the car of the target elevator to visually understand the logic of controlling the door of the car of the target elevator at this time, the visible range in the elevator lobby when facing the elevator lobby from the car of the target elevator can be visually selected, and the visible range can be marked in the first image data as a danger zone, that is, the danger zone is the area of ​​the elevator lobby that is visually observable by the passengers in the car of the target elevator.

[0066] In the specific implementation, Figure 2-Figure 5 As shown, the second camera 232 is installed in the car 231 of each elevator 230 , that is, one second camera 232 can be installed in the car 231 of each elevator 230 .

[0067] For the first camera, the second image data [P1, P2, ..., Pj, ..., Pn] collected by the first camera facing the elevator lobby can be obtained. If the first camera is a movable camera, in addition to the second image data, the posture of the first camera can also be recorded.

[0068] For each second camera, on the one hand, the third image data [J1P0, J2P0, ..., JiP0, ..., JnP0] (JiP0 represents the third image data of the i-th elevator facing the elevator lobby when the door of the elevator car is closed, i∈n, n is the number of elevators) collected by each second camera when the door of the elevator car is closed is obtained. On the other hand, the door of each elevator car is controlled to open in sequence, so as to obtain the third image data of the second camera when the door of each elevator car is opened and facing the elevator lobby. The fourth image data of the set [J1P1, J2P1, …, JiP1, …, JnP1], [J1P2, J2P2, …, JiP2, …, JnP2], …, [J1Pj, J2Pj, …, JiPj, …, JnPj], …, [J1Pn, J2Pn, …, JiPn, …, JnPn] (JiPj represents the fourth image data collected in the j-th elevator facing the elevator lobby when only the door of the car of the i-th elevator is open, representing i∈n, where n is the number of elevators).

[0069] The difference between the third image data and the fourth image data is calculated to obtain difference image data. The difference between the third image data and the fourth image data mainly lies in whether the car door is open. When the car door is closed, the content of the third image data includes the car door. When the car door is open, the content of the fourth image data includes the external environment seen through the car door, and the external environment is mainly the elevator lobby.

[0070] Therefore, if Figure 3-Figure 5 As shown, the content of the difference image data is mainly the area of ​​the elevator lobby that is visually observable by the second camera 232. Since the vision of the second camera and the vision of the passengers have a high degree of overlap, the area of ​​the elevator lobby that is visually observable by the second camera can be equated with the area of ​​the elevator lobby that is visually observable by the passengers, that is, the content of the difference image data is mainly the area of ​​the elevator lobby that is visually observable by the passengers.

[0071] At this time, the homography matrix used to convert the coordinate system of the second camera into the coordinate system of the first camera is calculated, and the difference image data is multiplied by the homography matrix to project the difference image data into the second image data, and the visible range in the elevator lobby when facing the elevator car from the target elevator is obtained, and it is marked as the dangerous area 310.

[0072] Generally, the shape of the dangerous area 310 is a regular trapezoid. Therefore, when marking the dangerous area 310 , it is sufficient to record its four corner points 311 .

[0073] In addition, due to the installation position of the second camera, the content of the difference image data may include the side walls of the elevator lobby and / or the side walls of the elevator in addition to the area of ​​the elevator lobby visually observable by passengers.

[0074] Then, before projecting the difference image data into the second image data, pixel points representing the side walls of the elevator lobby and / or pixel points of the side walls of the elevator can be detected in the difference image data, and the pixel points representing the side walls of the elevator lobby and / or pixel points of the side walls of the elevator can be filtered out in the difference image data to leave pixel points representing the floor of the elevator lobby.

[0075] Furthermore, considering that the side walls of the elevator lobby, the side walls of the elevator and the car door all have a certain size relationship, the range adjacent to the car door setting in the difference image data can be determined. The confidence that the side walls of the elevator lobby and the side walls of the elevator exist within this range is relatively high, and the side walls of the elevator lobby and the side walls of the elevator are both regular graphics, so edge detection can be performed within this range to obtain pixel points representing the side walls of the elevator lobby and / or the side walls of the elevator.

[0076] Alternatively, the side walls of the elevator lobby and / or the side walls of the elevator are used as targets, and a target detection algorithm is used to detect pixel points representing the side walls of the elevator lobby and / or the side walls of the elevator in the difference image data.

[0077] Alternatively, multiple frames of difference image data are detected for the same elevator at multiple floors, and the pixel points representing the side wall of the elevator lobby and / or the pixel points of the side wall of the elevator are detected using a multi-frame difference method.

[0078] It should be noted that the first camera can learn the dangerous areas of each elevator offline, and store the mapping relationship between the first camera and the dangerous areas of the elevator (indicated by ID, etc.) in the database. When controlling the door of the car, the dangerous area is read from the database based on the first camera and the elevator (indicated by ID, etc.).

[0079] If the first camera is a movable camera, the mapping relationship between the first camera, posture and dangerous areas of the elevator (indicated by ID, etc.) can be stored in the database. When controlling the door of the car, the dangerous areas are read from the database based on the first camera, posture and elevator (indicated by ID, etc.).

[0080] Step 103: Detect animals in the dangerous area and in the car of the target elevator to obtain a first detection result.

[0081] In this embodiment, it is possible to detect whether animals exist in the dangerous area and in the car of the target elevator, respectively, to obtain a first detection result.

[0082] For the dangerous area, the dangerous area is extracted from the first image data to obtain regional image data.

[0083] Taking animals (such as cats, dogs, etc.) as targets, target detection is performed in the regional image data to obtain a first detection result of whether there are animals in the dangerous area.

[0084] For the car of the target elevator, the sixth image data collected by the second camera installed in the car of the target elevator can be obtained, and target detection is performed in the sixth image data with animals (such as cats, dogs, etc.) as the target to obtain the first detection result of whether there are animals in the car of the target elevator.

[0085] Alternatively, electromagnetic wave data collected by a radar installed in the cabin of the target elevator is obtained, and the electromagnetic wave data is used to detect in dimensions such as the normal volume of the animal and the position of the animal (as a whole at the bottom of the cabin) to obtain a first detection result of whether there is an animal in the cabin of the target elevator.

[0086] Step 104: Detect passengers in the elevator lobby and the elevator car of the target elevator to obtain a second detection result.

[0087] In this embodiment, it is possible to detect whether there are passengers in the elevator lobby and in the elevator car of the target elevator to obtain a first detection result.

[0088] For the elevator lobby, target detection is performed in the first image data with the human body as the target to obtain a second detection result of whether there are passengers in the elevator lobby.

[0089] For the car of the target elevator, the sixth image data collected by the second camera installed in the car of the target elevator can be obtained, and target detection is performed in the sixth image data with the human body as the target to obtain a second detection result of whether the car of the target elevator has passengers.

[0090] Alternatively, electromagnetic wave data collected by a radar installed in the cabin of the target elevator is obtained, and the electromagnetic wave data is used to detect in dimensions such as the normal volume of the human body and the position of the human body (feet at the bottom of the cabin) to obtain a second detection result of whether there is a human body in the cabin of the target elevator.

[0091] Step 105: Control the door of the target elevator car according to the first detection result and the second detection result.

[0092] In this embodiment, the first detection result and the second detection result are combined to identify, to a certain extent, the relationship between the passenger and the animal when the target elevator stops at the floor. The animal may be the passenger's pet, or it may be the pet of other users other than the passenger, or a stray animal. According to different relationships, the door of the target elevator car is adaptively controlled to open and / or close.

[0093] Furthermore, if Figure 2 and Figure 5 As shown, based on the first detection result, the following two situations can be divided. For these two situations, the second detection result is combined to determine the relationship between the passenger and the animal when the target elevator stops at the floor:

[0094] Situation 1: There are animals in the dangerous area

[0095] 1. If there is an animal in the danger zone and there are no passengers in the elevator lobby or the target elevator car, and there are no passengers to take care of the animal, the door of the target elevator car must not be opened to prevent the animal from walking from the elevator lobby to the target elevator car and getting lost on the current floor.

[0096] 2. If there is an animal in the danger zone, and there are passengers in the elevator lobby but no passengers in the target elevator car, then the animal is likely to be a pet of a passenger in the elevator lobby. In this case, the first prompt operation will be executed in the elevator lobby, and the door of the target elevator car will be opened according to the reference speed control. When the car door is open for more than the preset time, the door of the target elevator car will be closed according to the reference speed control.

[0097] Among them, the first reminder operation is used to remind passengers in the elevator lobby to take care of animals, so that when the animal is a pet of a passenger in the elevator lobby, the passengers in the elevator lobby will be careful to bring the animal into the elevator car of the target elevator, avoiding the situation where the passengers in the elevator lobby enter the elevator car of the target elevator while the animal is left in the elevator lobby.

[0098] For example, Figure 2 As shown, a first speaker 302 is installed in the elevator lobby 300. At this time, the first prompting operation is to call the first speaker 302 to play a first prompting message. The content of the first prompting message is to remind passengers in the elevator lobby to take care of animals.

[0099] 3. If there is an animal in the danger zone and there are passengers in the target elevator car, at this time, the animal is more likely not the pet of the passenger in the target elevator car, then the second prompt operation is performed in the target elevator car and the manual door closing mode is started.

[0100] The second prompt operation is used to prompt that the manual door closing mode is triggered due to the presence of an animal in front of the car of the target elevator.

[0101] For example, Figure 2 As shown, a second speaker 233 is installed in the car 231 of each elevator 230. At this time, the second prompt operation is to call the second speaker in the car of the target elevator to play the second prompt information. The content of the second prompt information is to prompt that the manual door closing mode is triggered due to the presence of an animal in front of the car of the target elevator.

[0102] The door of the car of the target elevator is opened according to the reference speed control, and thereafter, the door of the car of the target elevator is maintained in the open state.

[0103] In manual door closing mode, when a door closing operation is received by a passenger through a control panel, client, etc. in the car, the door of the target elevator car is closed, so that if an animal enters the target elevator car, the passengers in the target elevator car have enough time to drive the animal away, thereby preventing the animal from causing nuisance or even harming the passengers in the target elevator car, and also preventing the animal from entering the target elevator car and getting lost.

[0104] Furthermore, when closing the door of the car of the target elevator, the door of the car of the target elevator can be closed according to the reference speed control, or the speed can be reduced to control the closing of the door of the car of the target elevator to prevent animals from being pinched when driving away.

[0105] Then, when a passenger's door closing operation is received in the manual door closing mode, the reference speed for closing the door of the target elevator car in the automatic door closing mode is queried, the reference speed is subtracted from the preset step length or a specified ratio is taken from the reference speed to reduce the reference speed, the target speed is obtained, and the door of the target elevator car is closed according to the target speed.

[0106] Case 2: There is an animal in the target elevator car

[0107] 1. If there is an animal in the target elevator car, and there are no passengers in the elevator lobby but there are passengers in the target elevator car, then the animal is likely to be a pet of a passenger in the target elevator car. In this case, the third prompt operation is performed in the target elevator car, and the door of the target elevator car is opened according to the reference speed control. When the door of the car is open for more than the preset time, the door of the target elevator car is closed according to the reference speed control.

[0108] Among them, the third prompt operation is used to prompt the passengers in the car of the target elevator to take care of the animals, so that when the animal is the pet of the passengers in the car of the target elevator, the passengers in the car of the target elevator will pay attention to taking care of the animals, stay in the car of the target elevator together, or walk out of the car of the target elevator to the elevator lobby together, to avoid the situation where the passengers stay in the car of the target elevator while the animals walk out of the car of the target elevator to the elevator lobby, or the passengers walk out of the car of the target elevator to the elevator lobby while the animals stay in the car of the target elevator.

[0109] For example, Figure 2 As shown, a second speaker 233 is installed in the car 231 of each elevator 230. At this time, the third prompt operation is to call the second speaker in the car of the target elevator to play the third prompt information, and the content of the third prompt information is to remind the passengers in the car of the target elevator to take care of the animals.

[0110] 2. If there is an animal in the target elevator car and there are no passengers in the elevator lobby or the target elevator car, and there is no passenger to take care of the animal, the car door will be opened and the animal will be removed from the target elevator car to prevent the animal from staying in the target elevator car and causing nuisance or even harm to future passengers riding in the elevator.

[0111] In an example of an eviction operation, such as Figure 2 As shown, a sound wave generator 234 is installed in the car 231 of each elevator 230. At this time, the driving away operation is to call the sound wave generator in the car of the target elevator to emit high-frequency ultrasonic waves. These ultrasonic waves are irritating to animals and have the effect of driving them away.

[0112] After the removal operation is executed, if the animal stays in the elevator car for a certain period of time, a retention event is generated for the animal and pushed to an administrator, such as a building property manager, to notify the administrator to handle the event of the animal staying in the elevator car.

[0113] 3. If there is an animal in the target elevator car, and there are passengers in the elevator lobby and the target elevator car, the animal may be the pet of a passenger in the target elevator car or may not be the pet of a passenger in the target elevator car. In this case, the fourth prompt operation is executed in the target elevator car and the manual door closing mode is started.

[0114] The fourth prompt operation is used to prompt that the manual door closing mode is triggered due to the presence of an animal in the car of the target elevator.

[0115] For example, Figure 2 As shown, a second speaker 233 is installed in the car 231 of each elevator 230. At this time, the second prompt operation is to call the second speaker in the car of the target elevator to play the fourth prompt information. The content of the fourth prompt information is to prompt that the manual door closing mode is triggered due to the presence of an animal in the car of the target elevator.

[0116] The door of the car of the target elevator is opened according to the reference speed control, and thereafter, the door of the car of the target elevator is maintained in the open state.

[0117] In manual door closing mode, when a door closing operation is received by a passenger through a control panel, client, etc. in the car, the door of the target elevator car is closed, so that if an animal is stranded in the car of the target elevator, the passengers in the car of the target elevator have enough time to drive the animal away, thereby preventing the animal from causing nuisance or even harming the passengers in the car of the target elevator.

[0118] Furthermore, when closing the door of the car of the target elevator, the door of the car of the target elevator can be closed according to the reference speed control, or the speed can be reduced to control the closing of the door of the car of the target elevator to prevent animals from being pinched when driving away.

[0119] Then, when a passenger's door closing operation is received in the manual door closing mode, the reference speed for closing the door of the target elevator car in the automatic door closing mode is queried, the reference speed is subtracted from the preset step length or a specified ratio is taken from the reference speed to reduce the reference speed, the target speed is obtained, and the door of the target elevator car is closed according to the target speed.

[0120] 4. If there is an animal in the target elevator car, and there are passengers in the elevator lobby but no passengers in the target elevator car, then the animal is more likely to be a pet of a passenger in the elevator lobby and less likely to be a pet of a passenger in the elevator lobby. In this case, the fifth prompt operation is executed in the elevator lobby, and the door of the target elevator car is opened according to the reference speed control. When the door of the car is open for more than the preset time, the door of the target elevator car is closed according to the reference speed control.

[0121] The fifth prompting operation is used to prompt passengers in the elevator lobby to take care of their animals.

[0122] For example, Figure 2 As shown, a first speaker 302 is installed in the elevator lobby 300. At this time, the first prompting operation is to call the first speaker 302 to play the fifth prompting information. The content of the fifth prompting information is to remind passengers in the elevator lobby to take care of animals.

[0123] If the animal is a pet of a passenger in the elevator lobby, the passenger in the elevator lobby will take the animal away from the elevator car of the target elevator after being prompted. If the animal is not a pet of a passenger in the elevator lobby, the passenger in the elevator lobby will ignore the prompt.

[0124] If the animal still remains in the car of the target elevator after the fourth prompt operation is performed multiple times, an expulsion operation is performed on the animal in the car of the target elevator.

[0125] In an example of an eviction operation, such as Figure 2 As shown, a sound wave generator 234 is installed in the car 231 of each elevator 230. At this time, the driving away operation is to call the sound wave generator in the car of the target elevator to emit high-frequency ultrasonic waves. These ultrasonic waves are irritating to animals and have the effect of driving them away.

[0126] After the removal operation is executed, if the animal stays in the elevator car for a certain period of time, a retention event is generated for the animal and pushed to an administrator, such as a building property manager, to notify the administrator to handle the event of the animal staying in the elevator car.

[0127] In this embodiment, a target elevator is selected from multiple elevators. The target elevator is an elevator with a car parked at a floor, and a lobby is provided for each floor. A dangerous area is identified in the lobby before the target elevator. Animals are detected in the dangerous area and in the car of the target elevator, respectively, to obtain a first detection result. Passengers are detected in the lobby and in the car of the target elevator, respectively, to obtain a second detection result. The door of the car of the target elevator is controlled based on the first and second detection results. The dangerous area before the elevator car can identify the tendency of animals to enter the car in the dangerous area. By combining the presence of animals in the dangerous area, animals in the car, passengers in the lobby, and passengers in the car, the relationship between the target elevator and the animals when the target elevator is parked at the floor can be determined to a certain extent. Based on the different relationships, the door of the car of the target elevator is adaptively controlled, which increases the flexibility of the car door control and makes it more closely aligned with the actual situation. This reduces the separation between users and their pet animals and reduces the contact between users and non-pet animals when riding the elevator, thereby improving the safety of users and animals when riding the elevator.
