Description

Technical Field

[0001] This invention relates to the field of elevators, and more specifically to an elevator calling system based on a mobile terminal. Background Technology

[0002] Currently, elevators have enabled passengers to register elevator call signals using mobile terminals such as smartphones, as shown in published documents: CN201510468376.X, CN201610308146.1, CN201810410498.7, which greatly facilitates the elevator call operation for passengers and brings them convenience.

[0003] On the other hand, in daily life, we often encounter special scenarios where someone else needs to register the elevator call signal on our behalf:

[0004] Scenario 1: At 7:30 AM, Xiaoming leaves for school. To facilitate timely contact and prevent him from playing games on his phone, Xiaoming's mother bought him a children's smartwatch with basic calling and location tracking functions. After proper settings, the smartwatch allows Xiaoming's mother and Xiaoming to make calls and perform basic data transfers, enabling Xiaoming's mother to contact him promptly and obtain his real-time location. Xiaoming wears the smartwatch to school. To save Xiaoming's time waiting for the elevator, his mother uses her smartphone to remotely call the elevator for him (the departure floor is Xiaoming's floor—his home floor—and the destination floor is the first-floor lobby). This allows Xiaoming to quickly board the elevator upon arrival, saving him waiting time.

[0005] Scenario 2: To improve security, the residential complex where Mr. Li and Mr. Wang live has issued IC cards to each resident. These cards can only register the first floor and the resident's own floor, not other floors. Simultaneously, residents can also register for elevator access using their mobile phones, but this is also limited to the first floor of each building and the resident's own floor within that building; it cannot register other floors in other buildings besides the first floor, or other floors within their own building besides their own floor. One morning, Mr. Wang, who lives on the 5th floor, wants to go to Mr. Li's apartment on the 10th floor in another building in the same complex to play chess. To ensure that Mr. Wang can easily take the elevator from Mr. Li's first floor to his own 10th floor while minimizing Mr. Li's waiting time, they agree that when Mr. Li is about to arrive at the elevator lobby on Mr. Wang's floor, he will call Mr. Wang, who will then register the elevator access signal on Mr. Li's phone. As you can see, Mr. Li and Mr. Wang's method is quite complex. In fact, both Lao Li and Lao Wang's mobile phones have location tracking capabilities and can communicate with each other.

[0006] Therefore, how to solve the problem of a second person calling the elevator on behalf of the first person in the above scenario, so that the first person can take the elevator while minimizing their waiting time, has become a technical problem that needs to be addressed.

The first elevator path is the path between the current position of the first mobile terminal and the elevator hall. The first position is in spatial coordinate form, and the floor plan saves the elevator position and elevator path in spatial coordinate form.

[0072] Beneficial technical effects

[0073] The elevator calling method based on a mobile terminal of the present invention enables a second person to call the elevator on behalf of a first person so that the first person can take the elevator, while minimizing the waiting time. Attached Figure Description

[0074] Figure 1 This is a schematic diagram of the elevator calling method based on a mobile terminal according to the present invention. Detailed Implementation

[0075] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0076] Example 1

[0077] This embodiment provides an elevator calling method based on a mobile terminal. The mobile terminal includes a second mobile terminal held by a second person and capable of registering the destination floor of a first person's intended elevator with the first person. The second mobile terminal generates an elevator calling signal based on the first person's departure floor and destination floor and sends it to the first elevator. Figure 1 As shown, the elevator calling method includes the following steps:

[0078] Step S1: Activate the elevator call software pre-installed on the second mobile terminal;

[0079] Step S2: Determine that the first person will take the elevator;

[0080] Step S3: Determine the departure floor and destination floor of the first person;

[0081] Step S4: Determine the first elevator that the first person will take;

[0082] Step S5: Determine the elevator control device corresponding to the first elevator;

[0083] Step S6: Generate the first elevator call signal required for the first person to use the elevator;

[0084] Step S7: Send the first elevator call signal to the elevator control device corresponding to the first elevator.

[0085] The elevator call software here can be any software that can be installed on a second mobile terminal and can perform predetermined functions, such as: APP, WeChat mini program, etc.

[0086] The steps described above will be explained in detail below with the help of Example 1.

[0087] Example 1

[0088] Xiaoming leaves home for school at roughly the same time every school day morning. The process is roughly as follows:

[0089] As Xiaoming was leaving, he said goodbye to his mother, "I'm going to school now, goodbye, Mom!"

[0090] Mom responded to Xiaoming, "Be careful on the road and study hard. I'll register you for the elevator in advance!"

[0091] Xiaoming left his home and walked along the corridor to the elevator lobby (Xiaoming's home is on the 10th floor) to wait for the elevator;

[0092] After the elevator reached the 10th floor and opened, Xiaoming entered the elevator car, took the elevator to the 1st floor, and then left the elevator car to go to school.

[0093] To facilitate timely communication and prevent Xiaoming from being distracted at school, his mother prepared a children's smartwatch for him with only simple functions such as making calls, location tracking, and communication.

[0094] Here, Xiaoming corresponds to the first person mentioned earlier, and his mother corresponds to the second person mentioned earlier. His mother's smartphone is the second mobile terminal, and the smartphone has elevator calling software pre-installed on it. This elevator calling software is used to remotely call the elevator in the residential building where Xiaoming's family lives.

[0095] After Mom responds to Xiaoming's message, "I'll register for the elevator for you in advance!", she activates the elevator call app on her second mobile device (corresponding to step S1); and based on Xiaoming's call, she determines that Xiaoming will take the elevator (corresponding to step S2); since Xiaoming is going to school from home, the starting floor must be the 10th floor where his home is located, and the destination floor must be the 1st floor (corresponding to step S3); furthermore, the residential building only has one elevator, so Xiaoming must take that elevator (corresponding to step S4); after installing the elevator call app on her phone, Mom will use the information provided by the property management (elevator provider) (elevator signage and elevator control system) to... The corresponding relationship is established by recording the elevator identifier and control system in the elevator call software. This way, the elevator control system can be determined by selecting the elevator identifier through input operation. Since Xiaoming's residential building is only equipped with one elevator, the elevator control system can be directly specified by the elevator call software without external operation input (corresponding to step S5). Xiaoming's mother uses the elevator call software to generate an elevator call signal with the 10th floor as the departure floor and the 1st floor as the destination floor (corresponding to step S6). Xiaoming's mother uses the elevator call software to send the elevator call signal to the corresponding elevator control system (corresponding to step S7).

[0096] It should be noted that, in this example, since the first person to take the elevator is only Xiaoming, the residential building is equipped with only one elevator (and its control system is also unique), and Xiaoming's departure floor and destination floor are also unique, the contents of the above steps S3-S5 are fixed. Therefore, the contents determined in steps S3-S5 can be pre-saved in the elevator call software. In this way, every time the mother needs to register an elevator call signal for Xiaoming, she only needs to start the elevator call software, which will automatically generate an elevator call signal and send it to the elevator control system.

[0097] Example 2

[0098] This embodiment is similar to Embodiment 1, except that the methods for determining the departure floor and the destination floor are different.

[0099] The method for determining the departure floor and destination floor of the first person in step S3 is as follows:

[0100] The elevator calling software pre-saves floor pairs corresponding to the first person. The floor pairs consist of the first person's possible departure floor and possible destination floor. The floor in the floor pair that is the same as the floor where the second mobile terminal is currently located is determined as the departure floor, and the other floor is determined as the destination floor.

[0101] In this embodiment, the elevator calling software pre-saves floor pairs corresponding to the first person. Each floor pair consists of one possible departure floor and one possible destination floor for the first person. Specifically, the software first determines the current floor of the second person or the second mobile terminal, then uses the floor in the floor pair that matches the current floor of the second person or the second mobile terminal as the departure floor, and uses the other floor in the floor pair as the destination floor.

[0102] For example, similar to Example 1 in Implementation 1, the elevator calling software pre-saves Xiaoming's floor pair (1, 10). When Xiaoming leaves home to take the elevator, his mother's phone determines that his mother (or his mother's phone) is currently on the 10th floor (because both Xiaoming and his mother are on the 10th floor of their home, this is Xiaoming's current floor). Therefore, 10 is used as the departure floor and 1 is used as the destination floor.

[0103] It should be noted that the method for determining the departure floor and destination floor in this embodiment requires that the first person and the second person (i.e., the first mobile terminal and the second mobile terminal) are currently located on the same floor; when there are multiple floor pairs, the floors where the first person and the second person in each floor pair are currently located are different.

[0104] Example 3

[0105] This embodiment provides further supplementary explanations based on Embodiment 1 or Embodiment 2.

[0106] Step S6 further includes: determining the sending time for sending the first call signal to the elevator control device corresponding to the first elevator; step S7 sends the first call signal to the elevator control device corresponding to the first elevator at the sending time.

[0107] In this embodiment, the sending time is manually specified by a second person.

[0108] For Example 1, the mother will estimate the time it will take for Xiaoming to walk from home to the elevator lobby based on experience (Xiaoming's walking speed and the length of the elevator path between home and the elevator lobby). Then, she will take the time that is slightly shorter than the time it will take for Xiaoming to walk from home to the elevator lobby as the sending time and send the elevator call signal to the elevator control device corresponding to the first elevator at the sending time.

[0109] Example 4

[0110] This embodiment is similar to Embodiment 2, except that in Embodiment 2, the elevator calling software was manually activated by the mother, while in this embodiment, the elevator calling software is activated automatically.

[0111] In this embodiment, step S1 determines whether the first person's elevator riding behavior has a time pattern, and if the determination result is yes, the elevator calling software is activated at a preset time based on the time pattern.

[0112] When the first person's elevator use follows a certain pattern, this pattern can be used to automatically activate the elevator calling software.

[0113] In Example 1, Xiaoming leaves home at roughly the same time every school day to take the elevator to school; that is, Xiaoming's elevator ride times are roughly the same. Therefore, a time-triggered event can be created on the mother's phone, based on a start time slightly earlier than Xiaoming's departure time. This event will trigger the elevator calling software for remote elevator access when the current time reaches the start time. This is similar to setting an alarm clock, except the alarm sound is used to activate the elevator calling software.

[0114] Example 5

[0115] This embodiment is a further supplement to the aforementioned Embodiment 1.

[0116] In this embodiment, the mobile terminal also includes a first mobile terminal held by the first person but unable to register the first person's destination floor with the first elevator. The first mobile terminal is capable of communicating with the second mobile terminal and has a positioning module for determining the first location of the first mobile terminal.

[0117] The elevator call software stores a pre-established matching relationship between a first mobile terminal and a second mobile terminal; after starting the elevator call software, step S1 sends a location request to the first mobile terminal according to the matching relationship and receives its feedback first location.

[0118] After receiving the location request, the first mobile terminal verifies the pre-saved identifier of the second mobile terminal. If the verification is successful, it sends the first location back to the second mobile terminal.

[0119] Typically, a correspondence is pre-established between a second mobile terminal that can receive a first location and a first mobile terminal that is the sender of the first location that the second mobile terminal can receive. One second mobile terminal can correspond to multiple first mobile terminals, but one first mobile terminal corresponds to only one second mobile terminal. This can prevent multiple second mobile terminals from generating and sending multiple call signals to the elevator control device for the same first person's elevator ride, thereby reducing the efficiency of elevator operation.

[0120] The matching problem between the first and second mobile terminals involves establishing a connection between them so that the second mobile terminal can clearly identify the recipient (i.e., who it is requesting the first location from) and, consequently, the recipient of the first location information. Specifically, after receiving the second party's identifier (e.g., a phone number) from its user, the first party sends an authentication request (containing its own first identifier) ​​to the second party. The second party parses the first identifier from the authentication request and saves it. In subsequent uses, when the second party requests the first party's first location, the first party only needs to verify using the saved, verified first identifier. After successful verification, the first party returns the first location information to the second party based on the second identifier. This process can be viewed as determining the access addresses of both parties.

[0121] This first position is used to achieve at least one of the following determinations:

[0122] (1) Determine that the first person will take the elevator;

[0123] (2) Determine the first person's departure floor and destination floor;

[0124] (3) Determine the first elevator that the first person who will be taking the elevator will take;

[0125] (4) Determine the elevator control device corresponding to the first elevator;

[0126] (5) Determine the time when the elevator call software sends the elevator call signal to the elevator control system.

[0127] In Example 1 above, to facilitate timely contact and prevent Xiaoming from being distracted at school, his mother prepared a children's smartwatch for him with only simple functions such as making calls, location tracking, and communication. Here, Xiaoming is the first person, and his smartwatch is the first mobile terminal.

[0128] Example 6

[0129] This embodiment, based on embodiment 5, provides a further detailed explanation of determining that the first person wants to take the elevator based on the first location of the first mobile terminal.

[0130] Specifically, step S2 determines that the first person will take the elevator when at least one of the following conditions is met:

[0131] Condition 1: The first position is located in the elevator path leading to the first elevator and is moving towards the first elevator;

[0132] Condition 2: The distance between the first location and the location of the first person's residence exceeds the threshold.

[0133] Explanation of Condition 1: When the first position is located in the elevator path leading to the first elevator and moves towards the first elevator, the first mobile terminal corresponding to the first position and its holder will be regarded as the first person to take the elevator; for example: in Example 1, there is only one elevator path between Xiaoming's house and the elevator lobby, so as long as Xiaoming leaves home, he will definitely be in this path. As long as Xiaoming moves along this path towards the elevator lobby, he will definitely be going to take the elevator. Therefore, it is determined that Xiaoming is going to take the elevator.

[0134] Explanation of Condition 2: The first person to take the elevator is determined based on the change in distance between the first location and the location of the first person's residence. For example, in Example 1, after Xiaoming leaves home, the distance between him and his residence will inevitably gradually increase. That is, the distance between Xiaoming and his residence reflects Xiaoming's departure to take the elevator and go to school. Therefore, the distance between Xiaoming and his residence can be used as the basis for judging whether Xiaoming will take the elevator.

[0135] Example 7

[0136] This embodiment, based on embodiment 5, provides a further detailed explanation of determining the departure floor and destination floor of the first person based on the first location of the first mobile terminal.

[0137] Step S3 determines the departure floor and destination floor of the first person using any of the following methods:

[0138] Method 1: The elevator calling software stores a pre-established floor pair corresponding to the first person. The floor pair consists of the first person's possible departure floor and possible destination floor. The floor in the floor pair that is the same as the floor where the second mobile terminal is currently located is determined as the departure floor, and the other floor is determined as the destination floor.

[0139] Method 2: The elevator calling software stores a pre-established floor pair corresponding to the first person. The floor pair consists of the first person's possible departure floor and possible destination floor. The floor in the floor pair that is the same as the floor where the first person is located is determined as the departure floor, and the other floor is determined as the destination floor.

[0140] Method 3: The elevator calling software stores pre-established floor pairs corresponding to the first person. Each floor pair consists of the first person's possible departure floor and possible destination floor. Each floor in the floor pair has a corresponding time attribute, and the departure and destination floors of the first person about to take the elevator are determined based on the current time. For example, during the morning school hours, Xiaoming will inevitably take the elevator from the 10th floor of his home to the 1st floor before leaving for school. Therefore, it can be determined that Xiaoming's departure floor is definitely the 10th floor and his destination floor is the 1st floor; the opposite is true during the afternoon school hours.

[0141] Example 8

[0142] This embodiment, based on embodiment 5, provides a further detailed explanation of determining the first elevator that the first person to be taking will take based on the first location of the first mobile terminal.

[0143] In the scenarios described above, it is assumed that Xiaoming can only use one elevator, meaning that only one elevator is configured in the building. However, in reality, many buildings have multiple elevators that are subject to group control. In this case, it is only necessary to replace the elevator in the aforementioned scenario with the responding elevator assigned by the group control system (the original elevator control system is replaced with an elevator group control system). This is almost identical to the previous scenario. It is important to note here that when a building has multiple elevators, and these elevators are not all under the control of the same group control system, such as when a building has at least two groups of elevators, each group acting as a group control unit, but the elevators in different groups operate independently. In this case, before generating the elevator call signal, the second mobile terminal first determines which elevator group Xiaoming intends to use, and then uses the method described in the previous scenario to generate the elevator call signal and send it to the corresponding elevator group control system.

[0144] Step S4 determines the first elevator that the first person will take using any of the following methods:

[0145] Method A: When there are multiple elevators located in different waiting halls, if the first position is located in a non-shared section of one of the waiting halls, then the elevator in that waiting hall is determined to be the first elevator.

[0146] Method B: When there are multiple elevators located in different waiting halls, calculate the distance between the first position and the multiple elevators, and determine the elevator with the smallest distance as the first elevator.

[0147] Example 9

[0148] This embodiment, based on embodiment 5, provides a further detailed description of the elevator control device corresponding to the first elevator, determined based on the first location of the first mobile terminal.

[0149] The method for determining the elevator control device corresponding to the first elevator in step S5 is as follows: a correspondence between elevators and their corresponding elevator control devices is established in advance, and the elevator control device corresponding to the first elevator is determined based on the established correspondence.

[0150] Example 10

[0151] This embodiment, based on embodiment 5, provides a further detailed explanation of the sending time when the elevator call software, which determines the first location of the first mobile terminal, sends the elevator call signal to the elevator control system.

[0152] Step S6 further determines the sending time for sending the first elevator call signal to the elevator control device corresponding to the first elevator, and step S7 sends the first elevator call signal to the elevator control device corresponding to the first elevator at the sending time.

[0153] The method for determining the sending time in step S6 is as follows: the elevator calling software determines the sending time based on the first position and the pre-stored building floor plan. The floor plan includes the elevator position and the elevator routes from different positions on the building floor plan to the elevator hall. The elevator position in the plan is the position on the floor plan that corresponds to the actual position of the elevator in the building.

[0154] More specifically, step S6 determines the sending time based on the first location and the floor plan, specifying the remaining travel time or distance before the first person arrives at the elevator lobby. The sending time is such that the remaining travel time or distance is not less than a threshold.

[0155] Step S6 determines the remaining travel distance according to the following steps:

[0156] Step A1: Determine the first corresponding position based on the first position. The first corresponding position is the position in the floor plan that corresponds to the actual position of the first mobile terminal in the building floor.

[0157] Step A2: Determine the length of the first elevator path based on the first corresponding position and the elevator position in the figure, and use the length of the first elevator path as the remaining travel distance. The first elevator path is the path between the current position of the first mobile terminal and the elevator hall.

[0158] The time interval between the sending time and the current time is not less than the remaining travel time.

[0159] Step S6 determines the remaining travel time according to the following steps:

[0160] Step B1: Determine the first corresponding position based on the first position. The first corresponding position is the position in the floor plan that corresponds to the actual position of the first mobile terminal in the building floor.

[0161] Step B2: Determine the length of the first elevator path based on the first corresponding position and the elevator position in the figure. The first elevator path is the path between the current position of the first mobile terminal and the elevator hall.

[0162] Step B3: Estimate the first person's moving speed using the first person's first position;

[0163] Step B4: Calculate the quotient of the length of the first elevator path obtained in step B2 and the moving speed obtained in step B3, and use the calculation result as the remaining moving time.

[0164] Step B3 further includes the following sub-steps:

[0165] Sub-step B31: Obtain the first position corresponding to any two different times;

[0166] Sub-step B32: Determine the first corresponding position for any two different times;

[0167] Sub-step B33: Determine the path length between the first corresponding positions located at the first positions at two different times;

[0168] Sub-step B34: Determine the time interval between two different moments;

[0169] Sub-step B35: Calculate the quotient of the path length obtained in sub-step B33 and the time interval determined in sub-step B34, and use the calculation result as the movement speed of the first person.

[0170] Example 11

[0171] This embodiment is similar to Embodiment 10, except that:

[0172] In this embodiment, the floor plan stores the elevator location and elevator route in spatial coordinates. Since the first location obtained by the first mobile terminal is also in spatial coordinates, when calculating the remaining travel distance and remaining travel time, it is not necessary to first convert the first location to map coordinates and then perform other processing, as in Embodiment 10. The spatial coordinates can be used directly for calculation.

[0173] Step S6 determines the remaining travel distance as follows:

[0174] The length of the first elevator path is determined based on the first position and the elevator position in the diagram, and the length of the first elevator path is used as the remaining travel distance. The first elevator path is the path between the current position of the first mobile terminal and the elevator hall. The first position is in spatial coordinate form, and the floor plan saves the elevator position and elevator path in spatial coordinate form.

[0175] Step S6 determines the remaining travel time according to the following steps:

[0176] Step D1: Determine the length of the first elevator path based on the first position and the elevator position in the diagram. The first elevator path is the path between the current position of the first mobile terminal and the elevator hall. The first position is in spatial coordinate form. The floor plan saves the elevator position and elevator path in spatial coordinate form.

[0177] Step D2: Estimate the first person's moving speed using the first person's first position;

[0178] Step D3: Calculate the quotient of the length of the first elevator path obtained in step D1 and the moving speed obtained in step D2, and use the calculation result as the remaining moving time.

[0179] Step D2 further includes the following sub-steps:

[0180] Sub-step D21: Obtain the first position corresponding to any two different times;

[0181] Sub-step D22: Determine the path length between the first positions corresponding to two different times;

[0182] Sub-step D23: Determine the time interval between two different times;

[0183] Sub-step D24: Calculate the quotient of the path length obtained in sub-step D22 and the time interval determined in sub-step D23, and use the calculation result as the first person's moving speed.

[0184] Example 12

[0185] Another scenario involves elevator passengers like elementary school students, whose elevator usage times are relatively fixed. An application is pre-installed on their first mobile terminal. This application is activated slightly before Xiaoming arrives at his building or the elevator lobby. Based on the distance between the first location and the pre-stored elevator lobby of his building, the application sends the first location to a second mobile terminal and requests the other terminal to register the elevator call signal. After receiving the request, the second mobile terminal establishes the elevator call signal (the method for determining the destination floor and departure floor is the same as in scenario 1) and sends it to the elevator control system.

[0186] For another need: Currently, many buildings, especially residential buildings, often issue IC cards to improve security. Residents need to swipe their cards to register their destination floor when taking the elevator from the first floor back to their home floor. However, for special groups such as primary school students or elderly people with poor memory, they may lose these cards and be unable to use the elevator (even if a replacement is issued, the process is repeated), causing difficulties for these groups. Considering that these special groups usually have mobile devices (such as wristbands, mainly used for location tracking), but their elevator usage times are random, for the first person, they manually activate an application pre-installed on their first mobile device. After activation, the first person sends their location to a second mobile device and requests the second device to register the elevator call signal. Upon receiving the request, the second mobile device establishes the elevator call signal (the method for determining the destination and departure floors is the same as in scenario 1) and sends it to the elevator control system.

[0187] To address the two scenarios above, this embodiment provides an elevator calling method based on a mobile terminal. The mobile terminal includes a first mobile terminal and a second mobile terminal. The first mobile terminal is held by the first person but cannot register the first person's destination floor with the first elevator. The first mobile terminal is communicatively connected to the second mobile terminal and has a positioning module for determining the first location of the first mobile terminal.

[0188] The second mobile terminal is held by the second person and is capable of registering the destination floor of the first elevator that the first person is about to take; the second mobile terminal generates an elevator call signal based on the departure floor and destination floor of the first person who is about to take the elevator and sends it to the first elevator;

[0189] The elevator calling method includes the following steps:

[0190] Step 1: Establish a communication connection between the first mobile terminal and the second mobile terminal based on the pre-established matching relationship between them;

[0191] Step 2: The second person sends the location of the first elevator to the first person after the first person arrives at the building where the second person is located.

[0192] Step 3: The first mobile terminal monitors the first distance between the first location and the first elevator location, and proceeds to the next step when the first distance is less than a preset distance threshold;

[0193] Step 4: The first mobile terminal sends first information to the second mobile terminal, the first information including at least a command to register the elevator call signal on behalf of the user;

[0194] Step 5: The second mobile terminal receives and responds to the first information to start the elevator call software pre-installed on the second mobile terminal;

[0195] Step 6: The elevator call software generates a call signal based on the first information and sends it to the elevator control device.

[0196] The required destination floor and the first elevator control device are pre-saved in the elevator call software on the second mobile terminal.

[0197] Example 13

[0198] In the aforementioned scenario, the location of the first elevator (waiting hall) is pre-saved by the mobile terminal. However, for temporary passengers such as visitors, the location of the first elevator (waiting hall) is unknown. To address this scenario, this embodiment provides an elevator calling method based on a mobile terminal, wherein the mobile terminal includes a first mobile terminal and a second mobile terminal, wherein...

[0199] The first mobile terminal is held by the first person but cannot register the first person's destination floor with the first elevator; the first mobile terminal is capable of communicating with the second mobile terminal and has a positioning module for determining the first location of the first mobile terminal;

[0200] The second mobile terminal is held by the second person and is capable of registering the destination floor of the first elevator that the first person is about to take; the second mobile terminal generates an elevator call signal based on the departure floor and destination floor of the first person who is about to take the elevator and sends it to the first elevator;

[0201] The elevator calling method includes the following steps:

[0202] Step 1: Determine the target building for the first person;

[0203] Step 2: Monitor the first distance between the first location and the target building, and proceed to the next step when the first distance is less than a preset distance threshold;

[0204] Step 3: Establish a communication connection between the first mobile terminal and the second mobile terminal based on the pre-established matching relationship between them;

[0205] Step 4: The first mobile terminal sends first information to the second mobile terminal, the first information including at least a command to register the elevator call signal on behalf of the user;

[0206] Step 5: The second mobile terminal receives and responds to the first information to start the elevator call software pre-installed on the second mobile terminal;

[0207] Step 6: The elevator call software generates a call signal based on the first information and sends it to the elevator control device.

[0208] Step 6 determines the destination floor and the first elevator control device using any of the following methods:

[0209] Method a: A correspondence is pre-established and stored between the first person's ID (i.e. the identifier of the first mobile terminal) and the target floor, the first elevator, and the first elevator control device. The target floor and the first elevator control device are determined using the identifier of the first mobile terminal based on this correspondence.

[0210] Method b: The first information also includes one of the first person's destination floor and the identifier of the target building or the identifier of the first elevator that the first person will take. Step 6 uses the first information to determine the destination floor and the first elevator control device.

[0211] Method c: The second person is located on the target floor of the first person's target building. The elevator call software pre-installed in the second mobile terminal determines the first person's target floor and the first elevator control device based on its own location.

[0212] 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.
