Description

Technical Field

[0001] This invention relates to the field of elevators, and more particularly to an elevator call registration system. Background Technology

[0002] Currently, many elevator systems offer passengers a mobile-based elevator calling system.

[0003] The method in the intelligent building system proposed in Reference 1 (CN107000971B) includes: establishing a proximity environment relative to elevators within the building; detecting the location of a user device within the proximity environment; determining the source floor and destination floor corresponding to the user device by a processor accessing user preferences corresponding to the user device, the user preferences indicating the source floor and the destination floor; and generating an elevator call for the elevator by the processor based on the source floor and the destination floor after the proximity system detects that the user device is within a predetermined distance from the elevator, the elevator call being either an immediate elevator call or a delayed elevator call based on the proximity of the user device to the elevator. Essentially, this method determines whether to register an elevator call signal immediately or delayed based on the distance between the passenger and the elevator.

[0004] The elevator system proposed in Document 2 (CN115557345A) for call registration using a user-held portable terminal includes: an elevator control device for controlling the operation of the car; a first wireless signal device installed in the waiting hall on any floor, which activates application software for call registration pre-installed in the portable terminal and simultaneously sends a wireless signal containing information required for waiting hall call registration; a second wireless signal device installed in the car, which sends a wireless signal containing information required for car call registration; the portable terminal includes a control unit that wirelessly connects to the first wireless signal device in the waiting hall by activating the application software to perform the waiting hall call registration process, and wirelessly connects to the second wireless signal device in the car to perform the car call registration process; the control unit has a first scanning mode that scans the wireless signal with a first cycle, and a second scanning mode that scans the wireless signal with a second cycle set to be shorter than the first cycle; the first scanning mode or the second scanning mode is set based on the waiting hall call registration mode and the car call registration mode provided in the application software. This system aims to suppress battery consumption while ensuring call registration response performance by setting the scanning cycle of mobile terminals located in the elevator lobby to be longer than that of mobile terminals located inside the elevator car. However, the system essentially sets different scanning cycles for mobile terminals based on their distance from the elevator (i.e., whether they are located on a landing or inside the elevator car).

[0005] As the above analysis shows, existing technologies determine whether to immediately or delay registering the destination floor and how to set the scanning cycle of the mobile terminal based on the distance between the mobile device and the elevator. However, whether deciding whether to immediately or delay registering the elevator call signal or setting the scanning cycle of the mobile device, it is insufficient to rely solely on the distance between the mobile device and the elevator, because the elevator's own operating status also has a significant impact. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides an elevator call registration system, including a wireless signal device installed on the floor and a mobile terminal carried by the passenger;

[0007] The wireless signal device receives elevator operation information from the elevator control system and calculates a first travel time based on the elevator operation information.

[0026] Step C3: The sum of the third time interval and the first period T1 is taken as the second movement time;

[0027] Step C4: Select a moment between the second travel time and the third travel time as the time point.

[0028] Preferably, the wireless signal further includes the current position of the elevator car; the mobile terminal estimates the first moving distance of the elevator car during the third moving time, determines the first position point of the elevator car after it continues to move the first moving distance from the current position, selects a selected point between the first position point and the departure floor, the distance between the selected point and the departure floor is not less than a second threshold, and takes the moment when the elevator car moves to the selected point as the time point.

[0029] Preferably, the second threshold is (T1+T2)*V, where V is the moving speed of the passenger carrying the mobile terminal.

[0030] Preferably, the wireless signal device transmits the wireless signal when the first movement time is less than a preset transmission time threshold, or when the distance between the current position of the elevator car and the departure floor is less than a preset distance threshold.

[0031] Preferably, the wireless signal device further determines the deceleration point of the floor where the elevator is located based on the elevator's specification data, and determines a fourth movement time based on the elevator's current direction of travel. The fourth movement time refers to the movement time required for the elevator to move from its current position to the deceleration point corresponding to the current direction of travel. The wireless signal also includes the fourth movement time.

[0032] Preferably, when the elevator car has passed the deceleration point in the current direction of travel, the wireless signal device assigns the fourth travel time a non-positive real value.

[0033] Preferably, the selected scanning period condition further includes: condition 2, the elevator car has not yet passed the deceleration point within the selected scanning period.

[0040] Step A3: Select a time point between the first receiving time and the deceleration time as the time point. The second time point is the time point obtained by shifting forward by the third travel time from the arrival time of the elevator car at the departure floor.

The mobile terminal determines whether the congestion level of the departure floor meets the congestion level threshold preset in the mobile terminal. If it does not meet the threshold, the time point determined by the mobile terminal is delayed by at least the third travel time based on the current time.

[0050] Compared with the prior art, the technical solution of the present invention makes the time point of elevator call signal registration, as well as the scanning cycle of wireless signal device and mobile terminal, more reasonable and accurate. Attached Figure Description

[0051] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0052] Figure 1 This is a schematic diagram of the elevator call registration system of the present invention. Detailed Implementation

[0053] The following specific embodiments illustrate the implementation of the present invention. 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.

[0054] Example 1

[0055] like Figure 1 As shown, this embodiment provides an elevator call registration system, including a wireless signal device installed on the floor and a mobile terminal carried by the passenger.

[0056] The wireless signal device receives elevator operation information from the elevator control system and calculates a first travel time based on the elevator operation information. The first travel time is the time required for the elevator to move from its current position to the departure floor of the passenger carrying the mobile terminal (at least the direction of operation when the elevator car approaches and stops at the departure floor is the same as the direction the passenger expects to take the elevator). The elevator operation information includes at least the current position of the elevator car and the direction of operation of the elevator.

[0057] The wireless signal device transmits wireless signals to the outside world wirelessly, and the wireless signals include the first movement time;

[0058] When the first movement time is less than a preset transmission time threshold, or when the distance between the current position of the elevator car and the departure floor is less than a preset distance threshold, the wireless signal device transmits the wireless signal to the outside.

[0059] The mobile terminal calculates a third movement time based on the passenger's current location and movement speed. The third movement time is the time required for the passenger to move from the current location to the elevator.

[0060] The mobile terminal receives the wireless signal and determines the time point for registering the elevator call signal based on the first travel time and the third travel time, and sends the elevator call signal to the elevator control system via the wireless signal device at the time point.

[0061] When the wireless signal device is located on the terminal floor, the wireless signal may only include the first travel time; when the wireless signal device is located on an intermediate floor, the wireless signal includes at least the first travel time and its corresponding direction of travel (each intermediate floor corresponds to two first travel times: the first travel time going up and the first travel time going down). Usually, the direction of travel corresponding to the first travel time is consistent with the direction the passenger expects to take the elevator.

[0062] The wireless signal device updates the reception of elevator operation information and calculates and transmits the first movement time at a preset first cycle T1; the mobile terminal scans the signals transmitted by the wireless signal device at a second cycle T2.

[0063] The mobile terminal (such as a smartphone) has an application pre-installed for registering elevator call signals. The application has the passenger's destination floor and departure floor pre-stored (if the departure floor is not stored, it can be determined based on the departure floor in the wireless signal, or based on the mobile device's altitude positioning function, or other methods. There are no restrictions on how the departure floor is obtained).

[0064] (T1+T2)*V≤R, where V is the moving speed of the passenger carrying the mobile terminal, and R is the maximum coverage radius of the wireless signal transmitted by the wireless signal device. This allows passengers to automatically register their elevator call signals before arriving at the elevator. When (T1+T2)*V≤R is satisfied, the first period T1 is much shorter than the second period T2, which can significantly reduce the power consumption of the mobile terminal.

[0065] Preferably, the mobile terminal determines whether there is at least one selected scanning period for the departure floor based on the first travel time and the third travel time. The selected scanning period is a scanning period that meets the conditions for a selected scanning period, which include: Condition 1, the difference between at least one of the first travel times received by the mobile terminal within the selected scanning period and the third travel time is not less than a first threshold. The first threshold is the sum of the first period T1 and the second period T2.

[0066] Preferably, the wireless signal also includes the elevator's direction of travel, and the mobile terminal determines that the elevator exists when any of the following conditions are met, otherwise the determination result is that it does not exist: Condition 11, the departure floor is the terminal floor and the current direction of travel of the elevator is towards the terminal floor; Condition 12, the departure floor is not the terminal floor and the direction of travel of the elevator is consistent with the passenger's desired direction of travel, and the difference between the first travel time and the third travel time is not less than the quotient obtained by dividing the first threshold by the second period T2 and rounding it up.

[0067] When the judgment result is that it exists, the mobile terminal first selects a scanning period as the selected scanning period between the current time and the time interval between the current time and the first moving time. Then, it determines the time point within the selected scanning period, and the first time interval between the time point and the arrival time of the elevator car at the departure floor is not less than the third moving time.

[0068] When the determination result is that it does not exist, the time point determined by the mobile terminal is delayed by at least the third movement time based on the current time.

[0069] More specifically, mobile terminals can determine the time point in various ways depending on the circumstances.

[0070] Method 1: The mobile terminal determines the time point according to the following steps:

[0071] Step A1: Determine the first receiving time, where the first receiving time is the time when the mobile terminal receives the first moving time.

[0072] Step A2: Determine the second time point. The second time point is obtained by subtracting three travel times backward from the arrival time of the elevator car at the departure floor. Select a time point between the first reception time and the second time point as the selected time point. The above time order must be: current time, first reception time, and second time point, because if the second time point is earlier than the first reception time, the scanning period is selected in advance to ensure that the second time point is not earlier than the first reception time.

[0073] Method 2: The mobile terminal determines the time point according to the following steps:

[0074] Step B1: Subtract the first period T1 from the second period T2 and use the difference as the second travel time;

[0075] Step B2: Select a moment between the second travel time and the third travel time as the time point.

[0076] Method 3: When the wireless signal also includes the transmission time of the wireless signal device this time; the mobile terminal determines the time point according to the following steps:

[0077] Step C1: Determine the first receiving time, where the first receiving time is the time when the mobile terminal receives the first moving time;

[0078] Step C2: Calculate the third time interval, which is the time interval between the first receiving time and the sending time of the wireless signal device this time;

[0079] Step C3: The sum of the third time interval and the first period T1 is taken as the second movement time;

[0080] Step C4: Select a moment between the second travel time and the third travel time as the time point.

[0081] Method 4: When the wireless signal also includes the current position of the elevator car; the mobile terminal estimates the first moving distance of the elevator car during the third moving time, determines the first position point of the elevator car after it continues to move the first moving distance from the current position, selects a selected point between the first position point and the departure floor, wherein the distance between the selected point and the departure floor is not less than a second threshold, and takes the moment when the elevator car moves to the selected point as the time point. The second threshold is (T1+T2)*V, where V is the moving speed of the passenger carrying the mobile terminal.

[0082] Example 2

[0083] Based on Embodiment 1, the wireless signal device in this embodiment also determines the deceleration point of the floor where the elevator is located according to the elevator's specification data, such as the rated speed and acceleration. The deceleration point also includes two deceleration points, one for going up and one for going down. It also determines a fourth travel time based on the elevator's current direction of travel. The fourth travel time refers to the travel time required for the elevator to move from its current position to the deceleration point corresponding to the current direction of travel. The wireless signal also includes the fourth travel time (at this time, the wireless signal includes at least the first travel time, the fourth travel time, and the elevator's direction of travel).

[0084] When the elevator car has passed the deceleration point in the current direction of travel, the wireless signal device assigns a non-positive real value (such as 0 or a negative number) to the fourth travel time, so that the mobile terminal can determine whether the elevator car has passed the deceleration point based on the value of the fourth travel time.

[0085] The selected scanning period conditions also include: Condition 2, the elevator car has not yet passed the deceleration point within the selected scanning period.

[0086] The wireless signal also includes the elevator's direction of travel, and the mobile terminal determines that the elevator exists when any of the following conditions are met, otherwise it determines that the elevator does not exist:

[0087] Condition 21: The departure floor is the terminal floor and the current direction of the elevator is towards the terminal floor;

[0088] Condition 22: The departure floor is not an end floor, the elevator's direction of travel is consistent with the passenger's desired direction of travel, the difference between the first travel time and the third travel time is not less than the quotient obtained by dividing the first threshold by the second period T2 and rounding it up, and the fourth travel time is greater than 0. The first threshold is the sum of the first period T1 and the second period T2.

[0089] When the determination result is that it exists, the mobile terminal first selects a scanning period as the selected scanning period between the current time and the time interval between the current time and the fourth moving time. Then, it determines a time point within the selected scanning period, and the first time interval between the time point and the arrival time of the elevator car at the departure floor is not less than the third moving time.

[0090] The mobile terminal determines the time point according to the following steps:

[0091] Step A1: Determine the first receiving time, where the first receiving time is the time when the mobile terminal receives the first moving time;

[0092] Step A2: Determine the deceleration time when the elevator car reaches the deceleration rate (i.e., the time when the fourth travel time has elapsed since the current time);

[0093] Step A3: Select a time point between the first receiving time and the deceleration time as the second time point. The second time point is the time obtained by subtracting a third travel time from the arrival time of the elevator car at the departure floor. The first receiving time must be earlier than the deceleration time, because if the latter is earlier than the former, the former can be reported as earlier than the latter by pre-selecting the scanning period.

[0094] When the determination result is that it does not exist, the time point determined by the mobile terminal is delayed by at least the third movement time based on the current time.

[0095] When the mobile terminal determines that the elevator exists, and when the departure floor is the terminal floor, and the current direction of the elevator is towards the terminal floor, the time point determined by the mobile terminal is the current time.

[0096] Example 3

[0097] The difference between this embodiment and Embodiment 1 is that the mobile terminal has an elevator call registration interface, and the mobile terminal obtains the destination floor through the passenger's input on the elevator call registration interface.

[0098] The selected scanning cycle condition also includes: Condition 3, the time to obtain the target floor is less than the fourth movement time. When the determination result is that it does not exist, the time point determined by the mobile terminal is delayed by at least the third movement time based on the current time.

[0099] When the mobile terminal provides the elevator registration interface to the passenger, it prompts the passenger that if the registration is completed within a preset time (i.e., the difference between the time it takes for the car to move to the deceleration point and the fourth moving time), the passenger can immediately take the elevator (usually an elevator that will immediately reach the passenger's floor).

[0100] Example 4

[0101] Based on the aforementioned embodiments, in this embodiment, after the mobile terminal registers the elevator call signal or determines the time point for registering the elevator call signal, it stops scanning the signal of the wireless signal device to further save energy.

[0102] Example 5

[0103] Based on Example 1, in this example, when the mobile terminal determines that the elevator does not exist, if the elevator passes through the deceleration point of the departure floor, the departure floor, and the destination floor in the order of the elevator's current running direction, the mobile terminal continuously scans the signal of the wireless signal device.

[0104] The purpose of this is that, during the elevator's journey to the departure floor, the original first and third times may change due to the new stopping floor between the original position and the departure floor (caused by registration signals inside the car or on the floor). This allows passengers who previously missed the elevator to now be able to take it. This process essentially re-verifies the conditions in Example 1.

[0105] Example 6

[0106] Based on Example 1, the elevator operation information in this example also includes the congestion level of the elevator arriving at each floor. The mobile terminal determines whether the congestion level of the departure floor meets the congestion threshold preset in the mobile terminal. If it does not meet the threshold, the time point determined by the mobile terminal is delayed by at least the third travel time based on the current time.

[0107] 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.
