Description

Technical Field

[0001] This invention relates to the field of elevator control, and more particularly to a gate call method and access control elevator system based on indoor positioning. Background Technology

[0002] Among the relevant technologies, there is a non-contact elevator calling linkage method that can complete the elevator calling action without the user actively pressing a button. This method includes calling the elevator in conjunction with the access control gate, calling the elevator using a mobile APP, and calling the elevator by scanning a code.

[0003] However, this elevator call linkage method has some drawbacks. For example, users are only guaranteed to reach their target floor if they enter the elevator they called. However, elevator platforms often have multiple doors, so there's a chance users might take the wrong elevator, preventing them from reaching their destination and rendering the called elevator useless. This is especially true during peak elevator usage times, when the chance of users taking the wrong elevator increases significantly, making it more likely that the called elevator will arrive at the target floor but no one will be there. This not only wastes time for both passengers and those waiting, but also wastes elevator energy. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a gate call method and an access control elevator system based on indoor positioning.

[0005] The technical solution adopted by this invention to solve its technical problem is: to construct a gate call method based on indoor positioning, which is applied to an access control elevator system and includes the following steps:

[0006] S1: Receive terminal information from the user terminal at the access control gate, the terminal information including the target floor information that the user wants to reach;

[0007] S2: Call the elevator based on the target floor information and output an action signal to open the access control gate;

[0008] S3: After the user enters the elevator, locate the user terminal and obtain the terminal information; based on the terminal information, determine whether the elevator currently in use is the same elevator as the one called in step S2; wherein, if it is determined that the elevator called is not the same as the elevator currently in use, proceed to step S4.

[0009] S4: Update the floor list of the elevator currently in use based on the terminal information obtained inside the elevator.

[0010] In some embodiments, step S3 includes:

[0011] S321: After the user enters the elevator, locate the user terminal and obtain the terminal information; based on the terminal information, determine whether the target floor information is included in the floor stop list of the currently used elevator;

[0012] S322: When it is determined that the target floor information is included in the floor stop list of the currently used elevator, it is determined that the called elevator is the same as the currently used elevator, and the stop of the currently used elevator is controlled according to the current floor stop list.

[0013] If it is determined that the target floor information is not in the floor stop list of the currently used elevator, then it is determined that the called elevator is different from the currently used elevator, and step S4 is executed.

[0014] In some embodiments, step S4 includes the following sub-steps:

[0015] S421: Determine whether the target floor information belongs to the floor access list of the currently used elevator;

[0016] If so, the target floor information is added to the list of floors currently occupied by the elevator.

[0017] If not, proceed to step S422;

[0018] S422: Output guidance information to guide the user to exit the elevator at a floor that is adjacent to the target floor and belongs to the list of floors that the current elevator is currently in use.

[0019] In some embodiments, step S3 includes the following sub-steps:

[0020] S311: After calling the elevator, generate elevator call information corresponding to the terminal information;

[0021] S312: After the user enters the elevator, locate the user terminal and obtain the terminal information; determine whether the elevator call information corresponding to the terminal information matches the called elevator; if yes, determine that the called elevator is the same as the currently used elevator, and control the stopping of the currently used elevator according to the current floor stop list; if no, determine that the called elevator is not the same as the currently used elevator, and execute step S4.

[0022] Step S4 includes the following sub-steps:

[0023] S411: Determine whether the target floor information is included in the floor stop list of the currently used elevator; if yes, control the stop of the currently used elevator according to the current floor stop list; if no, proceed to step S412.

[0024] S412: Determine whether the target floor information belongs to the floor access list of the currently used elevator; if yes, add the target floor information to the floor access list of the currently used elevator; if no, proceed to step S413.

[0025] S413: Output guidance information to guide the user to exit the elevator at a floor adjacent to the target floor that belongs to the floor access list of the currently used elevator.

[0026] In some embodiments, the output guidance information, which directs the user to exit the elevator at a floor adjacent to the target floor that belongs to the elevator's current floor access permission list, includes:

[0027] Determine whether the floor information that belongs to the floor access permission list of the currently used elevator and is adjacent to the target floor exists in the floor access list of the currently used elevator;

[0028] If so, output the guidance information directly;

[0029] If not, add the floor information that belongs to the current elevator's floor access permission list and is adjacent to the target floor to the current elevator's floor access list, and output guidance information.

[0030] In some embodiments, when adding floor information to the floor docking list, the floor information in the floor docking list is sorted from low to high using a binary sorting method.

[0031] In some embodiments, after step S4, the following steps are further included:

[0032] S51: After updating the floor stop list of the currently used elevator, obtain the terminal information inside the called elevator;

[0033] S52: Based on the terminal information inside the called elevator, delete all floor information from the floor stop list of the called elevator except for the target floor information inside the called elevator.

[0034] The present invention also constructs an indoor positioning-based access control elevator system, including multiple elevators, at least one access control gate located on the first floor, a gate control system for controlling the access control gate, and an elevator control system for controlling the elevators, wherein the gate control system and the elevator control system are communicatively connected.

[0035] The gate control system includes a receiving module and an execution module; the receiving module is used to receive terminal information from the user terminal, including the target floor information that the user wants to reach; the execution module is used to call the elevator according to the target floor information and output an action signal to open the access gate.

[0036] The access control elevator system also includes a positioning system, which includes an antenna module and a communication module installed inside the elevator car; the antenna module is used to locate the user terminal after the user enters the elevator and obtain the terminal information; the communication module is used to communicate with the elevator control system.

[0037] The elevator control system includes a judgment module and a control module; the judgment module is used to determine whether the elevator currently being used by the user and the elevator being called are the same elevator based on the terminal information; the control module is used to control the elevator stops according to the floor stop list, and to update the floor stop list of the currently used elevator based on the terminal information obtained inside the elevator.

[0038] In some embodiments, the antenna module and / or the receiving module interact with the user's terminal via Bluetooth, NFC communication, or a mobile network to obtain the terminal information.

[0039] In some embodiments, the determining module is further configured to determine whether the target floor information is included in the floor stop list of the currently used elevator based on the terminal information, and to determine whether the target floor information belongs to the floor stop permission list of the currently used elevator.

[0040] The elevator control system also includes an output module for outputting guidance information.

[0041] Implementing this invention has the following beneficial effects: The elevator calling method constructed by this invention uses indoor positioning to scan and locate the terminal inside the elevator car after the user enters the elevator, determining whether the elevator the user is currently riding is the elevator they called. This can update the floor where the elevator the user is riding in real time when the user calls the wrong elevator, effectively ensuring that the user who takes the wrong elevator can still reach the target floor or a floor adjacent to the target floor, thereby improving the user experience, increasing elevator efficiency and reducing elevator energy consumption.

[0045] To provide a clearer understanding of the technical features, objectives, and effects of this invention, specific embodiments are now described in detail with reference to the accompanying drawings. In the following description, it should be understood that the orientations or positional relationships indicated by terms such as "front," "rear," "upper," "lower," "left," "right," "longitudinal," "horizontal," "vertical," "horizontal," "top," "bottom," "inner," "outer," "head," and "tail" are based on the orientations or positional relationships shown in the accompanying drawings, and are constructed and operated in a specific orientation. They are only for the convenience of describing this technical solution and do not indicate that the device or element referred to must have a specific orientation; therefore, they should not be construed as limitations on this invention.

[0046] It should also be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "linking," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. When an component is referred to as being "on" or "below" another component, the component can be located "directly" or "indirectly" on the other component, or there may be one or more intermediary components. The terms "first," "second," "third," etc., are only for the convenience of describing this technical solution and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0047] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0048] This invention constructs a gate-based elevator calling method based on indoor positioning. This method can be applied to an access control elevator system comprising multiple elevators and access gates located on the ground floor. Users must pass through the access gates to reach the elevator waiting platform and enter the elevator. In applications where this method is used, no call button is required in front of the elevator door, and no floor buttons are required inside the elevator car. In other words, from entering the gate to reaching the target floor, the user can call the elevator without touching any elevator buttons, achieving contactless elevator calling. Furthermore, this method can update the elevator's stopping floor in real time, effectively ensuring that users who take the wrong elevator can still reach their target floor or a floor adjacent to their target floor. This improves user experience, increases elevator efficiency, reduces elevator energy consumption, and enhances the accuracy of elevator floor location tracking.

[0049] In some embodiments, reference may be made to Figure 1 The method for calling the elevator through the turnstile may include the following steps:

[0050] S1: Receive terminal information from the user terminal at the access control gate. The terminal information includes the target floor information that the user wants to reach.

[0051] Understandably, the terminal information may include permission information regarding whether a user is authorized to pass through the access control gate; in other words, only authorized users can pass through the access control gate. Optionally, the terminal information may be preset in the user's terminal, which may include a card reader, mobile phone, etc. When the user arrives at the access control gate, they can interact with the receiving module on the access control gate using a contact / contactless method, allowing the access control elevator system to receive the user's terminal information. This interaction method can refer to existing technologies and will not be elaborated here.

[0052] The terminal information may also include the user's access permission information for the floors they can reach; for example, in some embodiments, the user is an office worker whose workstation is fixed on a certain floor, so the floor the user can reach is the floor where their workstation is located; of course, in other embodiments, the user's permission may also support them to access multiple floors, which is not specifically limited here.

[0053] The target floor information can be understood as containing information about the floor the user wishes to reach. As explained above, the floors a user can reach are restricted; only those with floor access permissions can access those floors. The target floor information is the floor the user wants to reach from one or more floors they have access to. This target floor information can be preset and stored on the user's terminal. When the user terminal is a mobile phone, the target floor can be set / modified through an APP application; when the user terminal is a card reader / writer, the target floor information can be written to the card reader / writer.

[0054] In step S1, after verifying that the user has permission to pass through the access control gate, the user's target floor information is obtained. In some embodiments, step S1 further includes the following steps:

[0055] Based on the access information, determine whether to open the gate; if yes, proceed to step S2; otherwise, output a signal indicating that the user is not authorized to enter to the user.

[0056] Optionally, when a user does not have access, information can be displayed directing the user to contact the property management level.

[0057] S2: Call the elevator based on the target floor information and output an action signal to open the access control gate;

[0058] In step S2, the principle of elevator calling can be to use the same elevator as much as possible for people going to the same or adjacent floors, in order to reduce elevator energy consumption and save users' waiting and riding time. Therefore, based on the target floor information of multiple users after passing through the access control gate and the above-mentioned elevator calling principle, one or more elevators can be assigned to multiple users, thereby obtaining a floor stop list for one or more elevators. The floor stop list includes information on the floors that the elevator needs to stop at when going up to the ground floor. In some practical scenarios, elevators are also set with stopping permissions, that is, elevators can only go to specified floors, such as odd / even floors; in this case, it is necessary to obtain a floor stop list for one or more elevators based on the target floor information of multiple users and the elevator stopping permissions.

[0059] Secondly, step S2 may optionally include the following sub-steps:

[0060] The system outputs information guiding users to the corresponding elevator door to wait.

[0061] Understandably, after obtaining the user's target floor information, it is necessary to open the access control gate to allow the user to pass through, and to guide the user to the corresponding elevator door to wait for the elevator. This information can be conveyed / feedback to the user when the user passes through the access control gate. In some embodiments, a display screen can be set at the access control gate to display the elevator number through the display module after the elevator call action is performed, so as to guide the user to the corresponding elevator door to wait for the elevator.

[0062] S3: After the user enters the elevator, locate the user terminal and obtain the terminal information; based on the terminal information, determine whether the elevator being called is the same elevator as the one currently in use; and if it is determined that the elevator being called is different from the one currently in use, execute step S4.

[0063] Optionally, when the elevator doors close, all user terminals located inside the elevator car are scanned and located simultaneously to obtain multiple terminal information. Based on the multiple terminal information, it is determined whether the elevator called by each user in the elevator car is the same elevator they are currently using. Of course, the user terminals of each user can also be located individually as users enter the elevator one after another.

[0064] In some optional embodiments, step S3 includes the following sub-steps:

[0065] S311: After calling the elevator, generate elevator call information corresponding to the terminal information;

[0066] S312: After the user enters the elevator, locate the user terminal and obtain the terminal information; determine whether the elevator call information corresponding to the terminal information matches the elevator being called; if yes, determine that the elevator being called is the same as the elevator currently in use, and control the stopping of the elevator currently in use according to the current floor stop list; if no, determine that the elevator being called is different from the elevator currently in use, and execute step S4.

[0067] Understandably, this elevator call information is a mapping to the elevator being called, containing the elevator number. After obtaining the terminal information through scanning and positioning, by determining whether the elevator call information corresponding to the terminal information matches the information of the called elevator, it can be determined whether the called elevator is the same elevator as the one currently in use. The information of the called elevator can be obtained from the elevator control system and is generated when the elevator is called.

[0068] In some alternative embodiments, it can be indirectly determined whether the called elevator is the same as the currently used elevator by judging whether the target floor information is included in the floor stop list of the currently used elevator; step S3 includes the following sub-steps:

[0069] S321: After the user enters the elevator, obtain and determine whether the target floor information is included in the floor stop list of the elevator currently in use, based on the user's terminal information.

[0070] S322: If it is determined that the target floor information is included in the floor stop list of the currently used elevator, then the elevator called is considered to be the same as the currently used elevator, and the stopping of the currently used elevator is controlled according to the current floor stop list; if it is determined that the target floor information is not included in the floor stop list of the currently used elevator, then the elevator called is considered to be different from the currently used elevator, and step S4 is executed.

[0071] Understandably, this method, as a means of determining whether the called elevator is the same as the currently used elevator, has the advantage of not needing to generate an additional elevator call information, and not needing to determine whether the target floor information is included in the floor stop list of the currently used elevator in step S4, thus simplifying the procedure. Although there may be cases where the target floor information is included in the floor stop list of the currently used elevator, but the called elevator is actually different from the currently used elevator (for example, there are two elevators that can reach the target floor, one of which is the called elevator, and the other is the currently used elevator), since the focus of this gate call method is to ensure that the user reaches the target floor, it is acceptable to accept the error and consider the inclusion of the target floor information in the floor stop list of the currently used elevator as the same as the called elevator.

[0072] S4: Update the floor list of the elevator currently in use based on the terminal information obtained inside the elevator.

[0073] Understandably, by confirming whether a user has entered the wrong elevator after entering, and upon detecting that the user has taken the wrong elevator, the elevator's floor list can be updated promptly by adding the target floor information to the floor list, ensuring the elevator stops at the target floor smoothly. Of course, in some elevator implementations with limited floor stops, updating the current elevator's floor list involves adding information about floors adjacent to the target floor to ensure the user reaches the target floor as quickly as possible, thus eliminating the inconvenience of the user having to return to the ground floor.

[0074] When adding the target floor information or the floor information adjacent to the target floor to the floor stop list, it is necessary to consider the upward movement of elevators on the first floor. That is, the stop floors should be sorted from low to high, and duplicate floors should be removed. In some embodiments, a binary sorting method can be used, which has a time complexity of O(nlogn), that is, 26 sorting operations can be completed for 20 people. For high-rise elevators, taking a typical passenger elevator carrying 20 floors as an example, the above calculation can be completed in milliseconds, so that the floor stop list can be updated the moment the user enters the elevator.

[0075] In some optional embodiments, after step S312 is performed, step S4 may include the following steps:

[0076] S411: Determine whether the target floor information is included in the floor stop list of the currently used elevator; if yes, control the stop of the currently used elevator according to the current floor stop list; if no, update the floor stop list of the currently used elevator.

[0077] Optionally, you may refer to Figure 2 After step S411, step S4 further includes the following sub-steps:

[0078] S412: Determine whether the target floor information belongs to the floor access list of the current elevator; if yes, add the target floor information to the floor access list; if no, proceed to step S413.

[0079] S413: Output guidance information to guide the user to exit the elevator on a floor that is adjacent to the target floor and belongs to the floor access permission list.

[0080] Further, optionally, step S413 includes the following sub-steps:

[0081] S4131: Determine whether the floor information adjacent to the target floor and belonging to the floor access permission list exists in the floor access list; if yes, output guidance information directly; if no, add the floor information adjacent to the target floor and belonging to the floor access permission list to the floor access list and output guidance information.

[0082] Understandably, the floor access permission list is a list of floors that an elevator can reach after its access permissions are set. For example, if an elevator can only go to odd-numbered floors, then the floor access permission list contains information about each odd-numbered floor.

[0083] Steps S412, S413, and S4131 are optimized steps for access control elevator systems with elevator stopping permissions; in access control elevator systems without elevator stopping permissions, step S411 can be executed directly.

[0084] Guidance information can be provided to users through screen displays, sound prompts, or other means to guide them.

[0085] The floor adjacent to the target floor and belonging to the floor access permission list can be the floor closest to the target floor in the floor access permission list. When there are two adjacent floors, the higher floor is preferred as the exit floor to reduce the pressure on users climbing stairs. For example, if the elevator is restricted to stopping only on odd-numbered floors, and the user wants to take the elevator to the 6th floor, then the floors closest to the target floor in the floor access permission list are the 5th floor and the 7th floor. The 7th floor is preferred as the exit floor for the user.

[0086] In some alternative embodiments, since steps S321-S322 have already determined whether the target floor information is included in the current elevator's floor stop list, step S4 may include the following steps after step S322 is completed:

[0087] S421: Determine whether the target floor information belongs to the floor access list of the current elevator; if yes, add the target floor information to the floor access list; if no, proceed to step S422.

[0088] S422: Output guidance information to guide the user to exit the elevator on a floor that is adjacent to the target floor and belongs to the floor access permission list.

[0089] Further, optionally, step S422 includes the following sub-steps:

[0090] S4221: Determine if the floor information adjacent to the target floor and belonging to the floor access permission list exists in the floor access list; if yes, output guidance information directly; if no, add the floor information adjacent to the target floor and belonging to the floor access permission list to the floor access list and output guidance information.

[0091] Secondly, after step S4, the following is also included:

[0092] S51: After updating the floor stop list of the currently used elevator, obtain the terminal information inside the called elevator;

[0093] S52: Based on the terminal information inside the called elevator, delete all floor information from the floor stop list of the called elevator except for the target floor information inside the called elevator.

[0094] Understandably, when the current elevator floor stop list needs to be updated, it means that the user has taken an elevator that is not the one they called. In this case, if there is no need to stop at the target floor in the originally called elevator, the user's original call instruction needs to be cancelled to prevent the elevator from going to waste.

[0095] In some embodiments, the present invention also constructs an indoor positioning-based access control elevator system, which may include multiple elevators, at least one access control gate located on the first floor, a gate control system for controlling the opening and closing of the at least one access control gate, and an elevator control system for controlling the up and down movement of the multiple elevators, wherein the gate control system and the elevator control system are communicatively connected.

[0096] Optionally, the gate control system may include a receiving module and an execution module.

[0097] The receiving module is used to receive terminal information from a user terminal. For example, the receiving module can interact with the user terminal via contact or contactless methods to obtain the user's terminal information. The user terminal may include a card reader / writer, a mobile phone, etc., and the interaction method may be Bluetooth, NFC communication, mobile network, etc. Optionally, the receiving module may include a first judging unit and a first acquiring unit. The first judging unit is used to judge whether the terminal information matches pre-stored permission data based on the terminal information; the first acquiring unit is used to acquire the user's terminal information.

[0098] The execution module is used to call for an elevator based on the target floor information and output an action signal to open the access control gate. For example, the execution module can output a signal to the elevator control system based on the target floor information, so that the elevator control system can control the elevator to stop at the first floor. Secondly, the execution module can also output an action signal to open the access control gate to control the access control gate to open the gate. Optionally, the execution module includes a first communication unit, a second communication unit, and a display unit. The first communication unit is used to output a signal to the elevator control system based on the target floor information to call for an elevator. The second communication unit is used to output an action signal to open the access control gate. The display unit is used to output information guiding the user to the corresponding elevator door. Further optionally, the display unit is a display screen.

[0099] Optionally, the positioning system may include an antenna module and a communication module installed inside the elevator car. The antenna module is used to locate the user terminal and acquire the user's terminal information; for example, after the user enters the elevator, the user terminal information is acquired by scanning and locating the user terminal. The interaction method can be Bluetooth, NFC communication, mobile network, etc. The communication module is used to communicate with the elevator control system to send the user's terminal information to the elevator control system.

[0100] Optionally, the elevator control system may include a judgment module and a control module.

[0101] The judgment module is used to determine whether the elevator being called is the same as the elevator currently in use, based on the user's terminal information. For example, the judgment module determines whether the elevator being called is the same as the elevator currently in use by checking whether the target floor information is included in the floor stop list of the currently used elevator.

[0102] The control module controls the elevator's stops based on the current floor stop list. For example, if the judgment module determines that the target floor is not in the current elevator's floor stop list, the control module updates the current elevator's floor stop list. This update involves adding the target floor, or a floor that is adjacent to the target floor and is already in the current elevator's floor stop list, to the current elevator's floor stop list.

[0103] Alternatively, the elevator control system may also include an output module for outputting guidance information to direct users to exit the elevator at a floor adjacent to the target floor and included in the floor access permission list. The output module may include a display screen, a speaker, etc.

[0104] Optionally, the elevator control system may also include a generation module, which generates elevator call information corresponding to the terminal information after an elevator call is made. Correspondingly, the judgment module is also used to determine whether the elevator call information corresponding to the terminal information matches the called elevator.

[0105] In some embodiments, the control module is further configured to delete floor information other than the target floor information in the floor stop list of the called elevator from the floor stop list.

[0106] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
