Description

TECHNICAL FIELD

[0001] The present application relates to the field of elevator technology, and in particular to an elevator call system. BACKGROUND

[0002] Currently, in order to facilitate passengers to register a call signal, more and more elevators provide a call method based on mobile terminals such as mobile phones for passengers. In this method, the mobile terminal receives the call information (such as the departure floor and the destination floor) input by the passenger or pre-stored in the mobile terminal and sends it to the elevator control system. As described in the following documents:

[0003] Document 1 (CN201980092071.X) provides an automatic call registration system for an elevator capable of suppressing a call registration that a user does not expect, which has a landing side beacon device provided at a landing, a sensor that detects an object entering or exiting a car, and a control device that, when a portable terminal automatically sends a request for a call that is pre-set in a call registration system application upon receiving an electric wave from the landing side beacon device, registers a landing call corresponding to the request automatically sent by the portable terminal, in the case where the sensor detects an object after the car arrives at the landing corresponding to the landing call and the door is opened, registers a car call corresponding to the request automatically sent by the portable terminal, and in the case where the sensor does not detect an object after the car arrives at the landing corresponding to the landing call and the door is opened, does not register a car call corresponding to the request automatically sent by the portable terminal.

[0004] Document 2 (CN202011349620.8) provides an elevator system that prevents false registration caused by wireless signals and correctly performs call registration in the call registration of a user using a terminal device. The elevator system has an elevator control device that controls the operation of a passenger car, and a plurality of first wireless signal devices provided in the waiting hall of each floor to start an application software for call registration pre-installed in a mobile terminal. The mobile terminal has a storage unit that stores boarding information including the boarding floor and the destination floor of the user, a wireless signal strength measurement unit that measures the wireless signal strength, and a control unit that, when the waiting hall call registration mode is set by the start of the application software, selects the first wireless signal device with the highest wireless signal strength among the first wireless signal devices as the connection object and performs registration processing of the waiting hall call according to the boarding information.

[0005] The prior art needs to set a wireless signal device called "beacon" at each landing of the building where the elevator is located, when a passenger carrying a mobile terminal with an application software for call registration pre-installed comes to the hall of any floor, the wireless signal sent by the wireless signal device starts the application software to call the passenger car, and the destination floor of the user is registered in the passenger car. Therefore, the prior art has the disadvantage of needing to set a wireless signal device called "beacon" at each landing. SUMMARY

[0006] A series of simplified concepts are introduced in the summary section, which are simplifications of the prior art in the art, which will be described in detail in the specific embodiments section. The summary section of the present application does not mean to try to limit the key features and necessary technical features of the claimed technical solution, nor to try to determine the protection scope of the claimed technical solution.

[0007] To solve the above technical problems, the present application provides an elevator call system, comprising a car beacon arranged on the car and broadcasting wireless signals externally in a wireless manner, and a mobile terminal carried by a waiting passenger;

[0008] The mobile terminal pre-installs an application software for registering a call signal, and starts the application software after receiving the wireless signal;

[0009] The coverage area of the wireless signal of the car beacon is a circle with the car beacon as the center and a radius R, and the radius R is such that the mobile terminal of the waiting passenger receives the wireless signal no later than the entry time of the elevator car into the deceleration interval corresponding to the floor where the waiting passenger is located;

[0010] The mobile terminal generates a call signal and sends it to the elevator control system.

[0011] Preferably, the square of the radius R is greater than or equal to the sum of the square of the deceleration distance and the maximum waiting distance; the deceleration distance is the distance between the deceleration point and the departure floor, and the maximum waiting distance is the maximum distance between the position where the waiting passenger enters the waiting hall and the elevator door.

[0012] Preferably, the wireless signal includes the running direction and the current position of the elevator car; the mobile terminal first determines the departure floor and the destination floor of the waiting passenger according to the floor pair pre-stored in the mobile terminal according to the current floor; then according to the running direction and the current position and the departure floor and the destination floor of the waiting passenger, it is judged whether the waiting passenger can enter the elevator car during the first time the mobile terminal receives the wireless signal broadcasted by the car beacon.

[0013]

[0013] Preferably, the mobile terminal determines the result as yes when the following conditions are met, and no otherwise: Condition 1, the elevator's direction of travel is consistent with the passenger's desired direction of travel; Condition 2, the elevator car is currently outside the deceleration zone; Condition 3, the departure floor is ahead of the elevator car's direction of travel.

[0014] Preferably, when the determination result is yes, if the mobile terminal generates and sends the elevator call signal for the first time, the mobile terminal blocks the wireless signal from the car beacon; if the mobile terminal does not receive the wireless signal from the car beacon, the blocking is lifted.

[0015] Preferably, when the judgment result is negative, after the mobile terminal generates and sends the elevator call signal for the first time, the mobile terminal continuously monitors the wireless signal and blocks the wireless signal from the car beacon during the period when the current state changes from receiving wireless signal to not receiving, then from not receiving to receiving, and then from receiving to not receiving again, and then cancels the blocking.

[0016] Preferably, during the period from when the mobile terminal first generates and sends the elevator call signal until the mobile terminal's location changes to the destination floor, the mobile terminal blocks the wireless signal from the car beacon; after the mobile terminal's location reaches the destination floor and it no longer receives the wireless signal, the blocking is lifted.

[0017] Preferably, the mobile terminal identifies which stage of the elevator ride is the waiting passenger based on the distance between itself and the car beacon and the position of the elevator car, and decides whether to block the wireless signal based on the identification result. The elevator ride stage includes the waiting stage, entering the car, moving with the car, and leaving the car.

[0018] Preferably, when the floor where the mobile terminal is located remains unchanged and the position of the elevator car changes, or when the floor where the mobile terminal is located remains unchanged and both the position of the elevator car and the second distance remain unchanged, the passenger is in the waiting stage; when the floor where the mobile terminal is located and the position of the elevator car remain unchanged but the second distance gradually decreases, the passenger is in the entering stage; when the position of the elevator car changes but the second distance remains unchanged, the passenger is in the moving stage with the elevator car; when the floor where the mobile terminal is located and the position of the elevator car remain unchanged but the second distance gradually increases, the passenger is in the leaving stage, where the second distance is the distance between the mobile terminal and the elevator car beacon.

[0019] Preferably, after the mobile terminal generates and sends the elevator call signal for the first time, the shielding state is maintained until the passenger is identified as leaving the elevator car and the second distance exceeds the threshold.

[0020] Preferably, a waiting hall contains multiple elevator cars, and each elevator car is equipped with an elevator car beacon; when the mobile terminal receives the wireless signal from the second elevator car beacon, the mobile terminal blocks the wireless signals from all elevator car beacons; after the mobile terminal is located at the destination floor and no longer receives the wireless signals, the blocking is lifted.

[0021] Technical effects:

[0022] Because beacons are installed only inside the car, the number of beacons can be significantly reduced, lowering costs and system complexity. Attached Figure Description

Those skilled in the art can fully understand other advantages and technical effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific embodiments, and the details in this specification can also be applied based on different viewpoints, with various modifications or changes made without departing from the overall design concept of the invention. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other. The following exemplary embodiments of the present invention can be implemented in many different forms and should not be construed as being limited to the specific embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary embodiments to those skilled in the art.

[0026] Example 1

[0027] This embodiment uses a single-elevator scenario as an example to illustrate the technical solution of this application.

[0028] like Figure 1As shown, in this embodiment, the elevator call registration system includes a car beacon (i.e., a wireless signal device) installed on the car and broadcasting wireless signals wirelessly, and a mobile terminal carried by waiting passengers; the mobile terminal is pre-installed with application software for registering elevator call signals, and the application software is launched after receiving the wireless signal;

[0029] The coverage area of ​​the car beacon's wireless signal is a circle with the car beacon as its center and a radius of R. The radius R is such that a mobile terminal located near a waiting passenger receives the wireless signal no later than the moment the elevator car enters the deceleration zone corresponding to the passenger's floor. The deceleration zone is the area obtained by moving up and down and then moving a certain distance, centered on the waiting floor. The mobile terminal generates an elevator call signal and sends it to the elevator control system.

[0030] The square of the radius R is greater than or equal to the sum of the squares of the deceleration distance and the maximum waiting distance; the deceleration distance is the distance between the deceleration point and the departure floor, which can be predetermined based on the elevator's rated speed and rated deceleration; the maximum waiting distance is the maximum distance between the location of the waiting passenger when entering the waiting hall and the elevator door, which can be obtained based on experience or historical data.

[0031] The reason for setting up beacons at each floor in the existing technology (hereinafter referred to as floor beacons, and correspondingly, the beacons set up in the elevator car are referred to as car beacons) is to ensure that after a passenger enters the waiting hall with a mobile terminal, the mobile terminal can receive the wireless signal broadcast by the floor beacon as soon as possible, so that the application software can be launched in time, and the passenger's elevator call signal can be generated and registered in time. However, in reality, even if the elevator call signal is registered in time, and the control system receives the elevator call signal from the mobile terminal and decides to respond to the elevator call signal, the actual response time is still the time when the elevator stops at the passenger's departure floor (and the running direction after starting is consistent with the passenger's expected elevator direction, which will be the default assumption hereafter, and will not be specifically pointed out or explained).

[0032] For example, if a passenger is currently on the 8th floor (departure floor is 8) and their destination floor is the 1st floor (desired direction is downward), and the mobile terminal generates a call signal and sends it to the elevator control system, but the elevator is on the 6th floor and moving upward, it still needs to wait for the elevator to reach its furthest expected stop in its upward direction (which could be the passenger's destination floor or the floor where the call signal was generated) before reversing direction and descending to the 8th floor to respond to the passenger's request (i.e., the call signal). Similarly, in the same example, if the elevator control system receives the call signal but the car is on the 12th floor and moving downward, the elevator will still respond to the passenger's request when it descends to the 8th floor. This shows that as long as the call signal is registered before the latest possible time for the elevator car to successfully stop at the 8th floor, the actual response time of the elevator to the passenger's call signal is the same, meaning it will not affect the passenger's elevator experience (in terms of waiting time). Therefore, if the mobile terminal can receive the wireless signal before the latest possible time to generate a waiting signal and send it to the elevator control system, then the same elevator riding experience as existing technologies can be achieved with a significant reduction in the number of beacons required. This involves the following two technical issues:

[0033] Question 1: How to determine the latest time that will allow the elevator car to successfully stop on the 8th floor?

[0034] Question 2: How to ensure that the mobile terminal can receive the wireless signal no later than the latest time?

[0035] Regarding question 1, considering that the elevator typically operates at its rated speed (though it may be below the rated speed due to not yet accelerating to a constant speed range) before stopping at the 8th floor, a deceleration point needs to be determined based on the current speed and rated deceleration. A deceleration curve from this point to the 8th floor needs to be planned, and the elevator control system controls the elevator car to follow this curve to successfully stop at the 8th floor. If a call signal is received before the elevator car passes the deceleration point, the control system will allow the elevator car to stop at the waiting point and respond to the call signal. If the call signal is received after the elevator car has passed the deceleration point, the elevator car will not have enough time to stop at the 8th floor and will only be able to respond when the elevator car stops at the 8th floor again. Therefore, for the elevator to respond to the waiting signal in the same instance, the waiting signal must be sent to the elevator control system before the elevator car reaches the deceleration point or at the deceleration point (not considering signal transmission and control system processing time). Thus, the latest possible time is when the elevator car reaches the deceleration point. Here, we consider the deceleration point furthest from the 8th floor (i.e., the rated speed before deceleration), and the distance between the deceleration point and the 8th floor is called the deceleration distance. Therefore, the deceleration distance can be determined in advance based on the elevator's rated speed and rated deceleration.

[0036] Regarding question 2, to ensure that mobile terminals receive the wireless signal no later than the latest possible time, it is necessary to guarantee that mobile terminals carried by passengers in the elevator lobby can receive the wireless signal broadcast by the car beacon when or before the elevator car reaches the deceleration point. This allows the application software to be activated, and the mobile terminal to generate a waiting signal and send it to the elevator control system. Therefore, the square of the coverage radius R of the wireless signal broadcast by the car beacon must be greater than or equal to the sum of the squares of the deceleration distance and the maximum waiting distance. The maximum waiting distance is the maximum distance between the passenger's position when entering the waiting lobby and the elevator door, and can be obtained based on experience or historical data.

[0037] Thus, when passengers carrying mobile devices enter the elevator lobby and then the elevator waiting area (where the distance between each location and the elevator door does not exceed the maximum waiting distance), the following scenarios can be considered:

[0038] Scenario 1: When a passenger enters the waiting area, the elevator car has not yet reached the deceleration point and is far away from it. Since the elevator car is far from the 8th floor at this time, the wireless signal of the car beacon is limited by the broadcast distance and cannot cover the waiting area. Therefore, the mobile terminal cannot receive the wireless signal and will not start the application software and register the waiting signal.

[0039] Scenario 2: As time progresses, the elevator car continues to move towards the 8th floor (and the deceleration point). As the distance between the elevator car and the 8th floor decreases (the distance between the car beacon and the mobile terminal also decreases accordingly), at a certain moment, the distance between the car beacon and the mobile terminal becomes less than the actual broadcast distance of the car beacon. At this point, the wireless signal broadcast by the car beacon reaches the waiting area, meaning the mobile terminal located in the waiting area enters the broadcast coverage area of ​​the car beacon. Therefore, the mobile terminal receives the wireless signal broadcast by the car beacon, the application software starts, generates an elevator call signal, and sends it to the elevator control system. Upon receiving the waiting signal, the elevator control system adds the 8th floor to the list of floors to be stopped and controls the elevator car to begin decelerating at the deceleration point until it finally stops at the 8th floor, allowing passengers to enter the car and receive elevator service.

[0040] Scenario 3: When a passenger arrives at the elevator waiting area, the elevator car has already passed the deceleration point (but has not yet passed the 8th floor). At this time, the distance between the car beacon and the mobile terminal is less than the actual broadcast distance of the car beacon. The mobile terminal receives the wireless signal broadcast by the car beacon, the application software starts, generates an elevator call signal, and sends it to the elevator control system. However, since the elevator car has already passed the deceleration point, the elevator cannot decelerate and stop at the 8th floor. Therefore, the elevator control system determines that the elevator will not have enough time to respond to the waiting signal when it passes the 8th floor. Thus, it adds the waiting signal to the list of waiting signals to be responded to and controls the elevator to respond to the call signal later.

[0041] Scenario 4: When a passenger arrives at the elevator waiting area, the elevator car has already passed the 8th floor and is moving away from it. However, at this time, the distance between the car beacon and the mobile terminal is less than the actual broadcast distance of the car beacon. The mobile terminal receives the wireless signal broadcast by the car beacon, the application software starts, generates an elevator call signal, and sends it to the elevator control system. However, since the elevator car is currently moving away from the 8th floor, the elevator control system adds the waiting signal to the list of waiting signals to be responded to and controls the elevator to respond to the call signal subsequently.

[0042] As the above analysis shows, the square of the radius R of the wireless signal coverage area of ​​the car beacon is greater than or equal to the sum of the squares of the deceleration distance and the maximum waiting distance. This ensures that even if the car beacon is only installed inside the car, passengers can still receive a timely response from the elevator car when they arrive at the waiting area before the elevator car passes the deceleration point (meaning that it stops at its departure floor so that passengers can board the elevator in time), achieving the same passenger experience as existing technologies (mainly in terms of waiting time).

[0043] Existing technologies require beacons on every floor, resulting in high system costs, structural complexity, time-consuming and labor-intensive installation, and potential impact on elevator lobby decor (especially important for later renovation projects). The most direct and readily apparent solution is to share a single beacon across multiple floors (e.g., two adjacent floors sharing one beacon). However, for buildings with a large number of floors (e.g., dozens or even hundreds in a high-rise), this is only a partial solution and cannot fundamentally overcome the shortcomings of existing technologies. This application, however, departs from the conventional thinking of reducing the number of beacons and fixing their placement. The technical solution derived from this application is based on multi-step reasoning.

[0044] Reasoning Step 1: By deeply analyzing the elevator calling method based on mobile terminals and beacons and the characteristics of the elevator operation control system's response to the elevator calling signal during this process, it was found that the actual response time to the elevator calling signal from the mobile terminal is still the time when the elevator stops at the passenger's departure floor.

[0045] Reasoning step 2: Further analysis revealed that as long as a call signal is received before the elevator reaches the corresponding deceleration point, the elevator's response to the call signal will be the same.

[0046] Reasoning step 3: Further analysis revealed that as long as the mobile terminal can generate an elevator call signal before the elevator car reaches the deceleration point of the passenger's departure floor and send it to the elevator control system, it will be sufficient.

[0047] Reasoning step 4: Further analysis shows that for a given elevator, the distance between the deceleration point and the floor (i.e., the deceleration distance) is fixed.

[0048] Reasoning step 5: Further analysis shows that as long as the mobile terminal can generate a call signal and send it to the elevator control system before the elevator car reaches the deceleration point of the passenger's departure floor, it can achieve the same performance as setting up a floor beacon on each floor.

[0049] Further analysis in reasoning step 6 shows that as long as a car beacon is installed in the elevator car and the mobile terminal receives the wireless signal from the car beacon before the elevator car reaches the deceleration point, the goal of reasoning step 5 can be achieved.

[0050] Reasoning step 7: As long as the coverage radius of the car beacon's wireless signal exceeds the deceleration distance (ignoring the distance between the passenger and the elevator), the mobile terminal can receive the wireless signal from the car beacon before the elevator car reaches the deceleration point (as can be seen from reasoning step 5, the deceleration distance is fixed).

[0051] Therefore, the technical solution of this application breaks away from the inherent framework of existing technologies and conventional solutions. It is a brand-new elevator calling system technical solution based on mobile terminals. This solution only requires the installation of car beacons in the elevator and the appropriate setting of the coverage radius of the car beacon's wireless signal to completely overcome the many shortcomings of existing technical solutions and has outstanding beneficial technical effects.

[0052] Example 2

[0053] In Example 1, because the mobile terminal is configured to launch the application software upon receiving the wireless signal from the car beacon broadcast, there is a problem where the mobile terminal repeatedly registers the waiting signal after continuously or repeatedly receiving the wireless signal from the car beacon broadcast. This example further adds technical features to Example 1 to solve the problem of repeated registration of waiting signals.

[0054] The wireless signal includes the elevator car's direction of travel and current position;

[0055] The mobile terminal first determines the departure and destination floors of waiting passengers based on its current floor using pre-saved floor pairs. Then, based on the direction of travel, current location, and the passenger's departure and destination floors, it determines whether the passenger can board the elevator car during the period when the mobile terminal first receives the wireless signal broadcast by the car beacon. The floor pairs consist of the passenger's possible departure and destination floors.

[0056] The mobile terminal determines "yes" when the following condition is met (i.e., it can enter the elevator car during the period when the mobile terminal first receives the wireless signal broadcast by the car beacon); otherwise, the determination result is "no":

[0057] Condition 1: The elevator's operating direction is consistent with the passenger's desired elevator direction; the desired elevator direction is determined based on the departure floor and the destination floor.

[0058] Condition 2: The elevator car is currently outside the deceleration zone;

[0059] Condition 3: The departure floor is located in front of the elevator car in the direction of travel.

[0060] When the determination result is yes, if the mobile terminal first generates and sends the elevator call signal, the mobile terminal blocks the wireless signal from the car beacon; or if the time for continuously receiving the wireless signal from the car beacon exceeds a preset time threshold, the mobile terminal blocks the wireless signal from the car beacon; when the mobile terminal no longer receives the wireless signal from the car beacon, the blocking is lifted.

[0061] When the judgment result is negative, after the mobile terminal generates and sends the elevator call signal for the first time, the mobile terminal continuously monitors the wireless signal and blocks the wireless signal from the car beacon during the period when the current state changes from receiving wireless signal to not receiving, then from not receiving to receiving, and then from receiving to not receiving again, and then cancels the blocking.

[0062] Alternatively, from the time the mobile terminal first generates and sends the elevator call signal until the mobile terminal's location changes to the destination floor, the mobile terminal blocks the wireless signal from the car beacon; or when the mobile terminal continuously receives the wireless signal from the car beacon for a period exceeding a preset time threshold, the mobile terminal blocks the wireless signal from the car beacon; and after the mobile terminal's location is the destination floor and it no longer receives the wireless signal, the blocking is lifted.

[0063] Alternatively, the mobile terminal can identify which stage of the elevator ride a passenger is in based on its own floor, the distance between itself and the car beacon, and the location of the elevator car, and decide whether to block the wireless signal based on the identification result. The elevator ride stage includes the waiting stage, entering the car, moving with the car, and leaving the car.

[0064] Specifically, when the mobile terminal's floor remains unchanged while the elevator car's position changes, or when the mobile terminal's floor remains unchanged while both the elevator car's position and the second distance remain unchanged, the passenger is in the waiting stage. When both the mobile terminal's floor and the elevator car's position remain unchanged but the second distance gradually decreases, the passenger is in the entering stage. When the elevator car's position changes but the second distance remains unchanged, the passenger is in the moving stage with the elevator car. When both the mobile terminal's floor and the elevator car's position remain unchanged but the second distance gradually increases, the passenger is in the leaving stage, where the second distance is the distance between the mobile terminal and the elevator car beacon.

[0065] After the mobile terminal generates and sends the elevator call signal for the first time, it remains in a shielded state until it detects that the passenger has left the car and the second distance exceeds the threshold.

[0066] Example 3

[0067] This embodiment considers a scenario where the building where the elevator is located is equipped with multiple elevators under group control.

[0068] A waiting hall contains multiple elevator cars, each equipped with a car beacon. When the mobile terminal receives the wireless signal from the second car beacon, the mobile terminal blocks the wireless signals from all car beacons. Once the mobile terminal is located at the destination floor and no longer receives the wireless signals, the blocking is lifted.

[0069] 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.
