Description

TECHNICAL FIELD

[0001] The present application relates to the field of elevators, in particular to an elevator call system suitable for a passenger using a mobile terminal to register a call signal. BACKGROUND

[0002] Nowadays, many elevators provide a call registration method based on a mobile terminal such as a mobile phone for a passenger to register a call signal. The passenger can register a call signal by operating the mobile terminal. When the passenger approaches the elevator, the mobile terminal establishes communication with the elevator control system and sends the call signal to the elevator control system through a mobile network. For details, please refer to CN201780061964.9, CN201810154745.1 and CN201810635328.9. This registration method based on distance only has the disadvantage of misregistration in some special situations, for example, a non-passenger passing through the elevator lobby to go to other places, as shown in FIG. 1, wherein the circular dotted area is the sensing area of the sensing device provided in the landing. When the non-passenger passes through the corridor A or the corridor B, he or she may be sensed by the sensing device, thus misregistration occurs. Obviously, although misregistration is not caused by the need of the non-passenger to take the elevator, the elevator will be less efficient due to the response to the call signal caused by misregistration. Figure 1

[0003] In addition, for remote call based on a mobile terminal, there is another phenomenon that seriously affects the efficiency of the elevator, that is, the passenger who remotely registers a call using a mobile terminal forgets to take the elevator in time due to forgetfulness or mischief, thus causing the elevator to make an invalid stop at the departure floor and seriously affecting the efficiency of the elevator. For this phenomenon, the prior art only counts the number of times that the passenger who remotely registers a call does not take the elevator and warns the passenger who remotely registers a call. This processing method has limited effect, especially for the passenger who registers a call for mischief.

[0004] Therefore, how to effectively reduce the impact on the efficiency of the elevator caused by the registration of a call signal (misregistration or mischief or registration and then forget to take the elevator) but not taking the elevator has become a technical problem to be solved. SUMMARY

[0005] The technical problem to be solved by the present application is to provide an elevator call system which can effectively reduce the adverse impact on the efficiency of the elevator caused by the registration of a call signal by a passenger who registers a call but does not take the elevator.

[0036] Further, the step of determining whether the mobile terminal is located in the elevator travel path includes the following steps:

[0048] Further, the transmission time determination unit estimates a moving distance of the reserved boarding passenger within the car moving time, and then takes a position obtained by moving the end point of the boarding path in the direction of the horizontal registration position by the moving distance or a certain point before the position as a specific point, and takes a time at which the reserved boarding passenger reaches the specific point as the transmission time.

[0049] Further, the transmission time determination unit estimates and monitors a passenger moving time required for the reserved boarding passenger to move from the terminal position currently output by the positioning unit to the elevator lobby, and takes a time at which a difference between the passenger moving time and the car moving time is equal to a time difference threshold value as the transmission time.

[0050] Further, the planning unit estimates a time required for the reserved boarding passenger to move from the terminal position currently output by the positioning unit to the elevator lobby according to a length of the boarding path, and determines a specific time using the time and the reserved boarding time, such that a time at which the reserved boarding passenger reaches the elevator lobby when departing for boarding not later than the specific time is not later than the reserved boarding time.

[0051] Further, the mobile terminal further comprises:

[0052] a reminding unit configured to issue a prompt to the reserved boarding passenger that the reserved boarding passenger should depart for boarding after reaching the specific time or after reaching a time that is ahead of the specific time by a specified time length.

[0053] Further, the judgment unit monitors whether the reserved boarding passenger immediately departs and whether the mobile terminal moves along the boarding path toward the elevator lobby, and determines that boarding malicious call is present when the judgment result is negative.

[0054] Further, the planning unit re-plans a boarding path using a current terminal position at a certain time before the specific time or at every set time length after registering the call signal, estimates a time required for the reserved boarding passenger to move from the current position of the mobile terminal to the elevator lobby according to the new boarding path, and re-determines the specific time.

[0055] Further, if the current terminal position from the positioning unit changes relative to the registered position, the planning unit re-plans the elevator boarding path according to the changed current terminal position, and adjusts the specific time and / or the departure floor for the reserved elevator boarding and modifies the elevator call signal.

[0057] The verification unit verifies whether the floor where the current position of the reserved elevator boarding passenger is located is consistent with the departure floor, and informs the passenger when the floor where the current position is located is not consistent with the departure floor.

[0058] Further, when the building where the elevator is located includes a plurality of elevator lobbies, the elevator call signal further includes a lobby identification, and the planning unit plans an elevator boarding path between the horizontal registered position and an elevator lobby corresponding to the lobby identification.

[0059] Further, when the building where the elevator is located includes a plurality of elevator lobbies, the mobile terminal further includes:

[0060] The selection unit selects one of the plurality of elevator lobbies as an elevator lobby for the planning unit to plan the elevator boarding path and informs the reserved elevator boarding passenger of the selection result.

[0061] Further, the selection unit selects an elevator lobby closest to the reserved elevator boarding passenger, or requests and receives elevator operation information from the elevator side, and selects an elevator lobby with the least number of passengers according to the elevator operation information.

[0062] Further, when the selection unit changes the originally selected elevator lobby, the determination unit determines whether the reserved elevator boarding passenger will take the elevator according to the determination result of the elevator boarding condition, and informs the reserved elevator boarding passenger of the changed selected elevator lobby when the reserved elevator boarding passenger will take the elevator.

[0063] Further, the mobile terminal further includes:

[0064] The reminding unit reminds the reserved elevator boarding passenger;

[0065] When the judging unit monitors that the reserved elevator passenger deviates from the current elevator path, the reminding unit reminds the reserved elevator passenger that the elevator hall the reserved elevator passenger is currently heading for is not the correct one; if the reserved elevator passenger adjusts to the correct elevator path, the original elevator path is followed, if the reserved elevator passenger insists on not returning to the correct elevator path, the planning unit re-plans the elevator path to the correct elevator hall according to the current position of the reserved elevator passenger, and the reminding unit informs the reserved elevator passenger of the re-planning result or re-selects the best elevator hall relative to the current position and plans the corresponding elevator path and informs the reserved elevator passenger; when the elevator hall is changed, the hall information in the original call signal is modified.

[0066] Further, if the reserved elevator passenger does not go to any elevator hall, the call signal is cancelled, and the judging unit determines that the reserved elevator passenger maliciously calls the elevator.

[0067] Further, the judging unit judges whether the mobile terminal moves along the elevator path to the elevator hall according to the following steps:

[0068] Step t1, selecting the length parameter β of the time window, the parameter β makes the time window include at least two time points;

[0069] Step t2, determining the terminal positions output by the positioning unit corresponding to the at least two time points in the time window;

[0074] Further, the elevator condition further includes:

[0075] Condition A, the reserved elevator passenger is located at the registration floor;

[0076] When the judging unit determines that condition A is established, the terminal sending unit sends the call signal to the elevator side part, otherwise the judging unit determines that the reserved passenger modifies the departure floor of the call signal to the current floor when going to the elevator hall of the current floor, and the terminal sending unit sends the modified call signal to the elevator side part.

[0077] Further, the mobile terminal further comprises:

[0078] The reminding unit informs the reserved passenger of the modified call signal.

[0085] Other advantages and embodiments of the present application will be disclosed in the following description with specific embodiments of the present application. The present application will be best understood by reference to the accompanying drawings, wherein:

[0086] Embodiment One

[0087] As shown in the following, the present embodiment is explained by the application scenario that the pre-boarding passenger uses the mobile phone to call the elevator. Figure 1

[0088] In the prior art, the App in the mobile phone of the pre-boarding passenger pre-registers the common calling content (such as the boarding direction or the destination floor) of the pre-boarding passenger. When the pre-boarding passenger carries the mobile phone to the nearby waiting hall and the distance between the mobile phone of the pre-boarding passenger and the Bluetooth induction device arranged in the landing is less than the induction distance, i.e. the mobile phone of the pre-boarding passenger enters the induction range, the Bluetooth communication between the mobile phone and the Bluetooth induction device is automatically established, and the App is automatically started. The calling signal is sent from the mobile phone to the elevator control system through the Bluetooth induction device, thereby completing the registration of the calling signal. As described in the background art, this method has the disadvantage of misregistration of the calling signal.

[0089] The present embodiment provides an elevator calling system aiming at the above-mentioned disadvantage, as shown in the following, which comprises an elevator side part and a mobile terminal (in the present embodiment, the smart phone of the pre-boarding passenger) for the pre-boarding passenger to register the calling signal, and the mobile terminal comprises: Figure 2

[0090] a storage unit for storing the structural layout of the building where the elevator is located, the structural layout comprising the position of the elevator waiting hall in the building and the path to the elevator waiting hall;

[0091] a positioning unit for generating and outputting the position of the mobile terminal as the terminal position, the terminal position comprising the position of the mobile terminal in the floor where it is located;

[0092] a terminal receiving unit for receiving the calling signal registered by the pre-boarding passenger, the calling signal comprising the departure floor and the boarding direction or the departure floor and the destination floor registered by the pre-boarding passenger using the mobile terminal, wherein the departure floor can also be determined by the signal receiving device (such as the Bluetooth device) arranged on the landing;

[0093] ​​a planning unit configured to plan a boarding path from a registration position to the elevator lobby according to the structure layout and the registration position, the registration position being the terminal position when the mobile terminal outputs a reservation boarding passenger registration call signal, the registration position including a horizontal registration position, the horizontal registration position being a position of the mobile terminal in a floor where the mobile terminal is located when the mobile terminal outputs a reservation boarding passenger registration call signal;

[0094] a judging unit configured to judge whether a boarding condition is satisfied, the boarding condition including that the mobile terminal is located in the boarding path;

[0095] a terminal sending unit configured to send the call signal to an elevator side when the judging unit judges that the boarding condition is satisfied.

[0096] the elevator side includes:

[0097] an elevator side receiving unit configured to receive the call signal from the mobile terminal;

[0098] a processing unit configured to generate an elevator call instruction according to the call signal received by the elevator side receiving unit and send the elevator call instruction to an elevator control system.

[0099] The following describes a manner in which the judging unit judges whether the mobile terminal is located in the boarding path.

[0100] Manner 1: the judging unit monitors a minimum distance, and judges that the mobile terminal is located in the boarding path when the minimum distance is less than a distance threshold, the minimum distance being a minimum value of distances between the terminal position currently output by the positioning unit and each point in the boarding path.

[0101] The judging unit can use the following two manners to determine the minimum distance.

[0102] Manner 1: the judging unit takes the terminal position currently output by the positioning unit as the center of a circle, gradually increases the radius of the circle until an intersection point with the boarding path appears, and takes the radius of the circle when the intersection point appears as the minimum distance.

[0103] Manner 2: the step of monitoring the minimum distance by the judging unit includes:

[0104] Step 1: selecting an unselected point from each point in the boarding path as a selected point;

[0105] when the distance between the terminal position currently output by the positioning unit and the horizontal registration position is not more than a distance threshold, selecting the selected point only from each point in the boarding path that is not more than a distance threshold from the horizontal registration position;

[0106] When the distance between the terminal position currently output by the positioning unit and the horizontal registration position exceeds a distance threshold, a circle is drawn with the terminal position currently output by the positioning unit as the center and the distance threshold as the radius, if the circle has no intersection with the elevator travel path, the judging unit directly determines that the mobile terminal is not in the elevator travel path, if the circle has only one intersection with the elevator travel path, the judging unit takes the intersection as the only selected point, if the circle has at least two intersections with the elevator travel path, the selected point is selected only from the elevator travel path located in the circle;

[0107] Step 2, the distance between the selected point and the terminal position currently output by the positioning unit is calculated;

[0108] Step 3, it is judged whether there is still an unselected point in each point of the elevator travel path, if yes, the step 1 is returned, otherwise, step 4 is entered;

[0109] Step 4, the minimum distance is selected from each distance obtained in step 2 as the minimum distance.

[0110] On this basis, the step of judging whether the mobile terminal is located in the elevator travel path includes the following:

[0111] Step A1, a sampling period T is set, the difference between the maximum moving distance S1 of the pre-booking elevator passenger and the moving distance S2 along the elevator travel path is less than a threshold value in the sampling period T, and S1 is less than or equal to the positioning error of the positioning unit, and at time t=k*T, the mobile terminal is in the elevator travel path, the position of the mobile terminal corresponds to a position point in the elevator travel path, wherein k is a non-negative integer (k=0, t=0 represents the current time);

[0112] Step A2, at time t=(k+1)*T, a circle is drawn with the position point as the center and the maximum moving distance S1 as the radius;

[0113] Step A3, the part of the elevator travel path located in the circle is taken as a selected elevator travel path segment;

[0114] Step A4, the distance between each point of the selected elevator travel path segment and the terminal position currently output by the positioning unit is calculated respectively;

[0115] Step A5, the minimum value of all distances calculated in step A4 is taken as the minimum distance, and it is judged whether the minimum distance is less than the distance threshold value, if yes, it is determined that the mobile terminal is located in the elevator taking path, and the position point is updated to the point in the elevator taking path corresponding to the minimum distance (because of the positioning error of the positioning unit, the mobile terminal in the positioning result may not be in the moving path, and the position point is always the point in the elevator taking path with the updated position point as the center of the circle, so as to eliminate the influence of the positioning error on the positioning result, thereby ensuring the accuracy of the position of the circle required in the subsequent judgment), otherwise it is determined that the mobile terminal is not located in the elevator taking path.

[0116] Method 2, the judgment unit draws a circle with the terminal position currently output by the positioning unit as the center and the maximum positioning error of the positioning unit as the radius, if the circle has at least one intersection point with the elevator taking path, it is determined that the mobile terminal is located in the elevator taking path, otherwise it is determined that the mobile terminal is not in the elevator taking path.

[0117] In addition, when the building where the elevator is located contains multiple elevator waiting halls, the elevator call signal further includes a waiting hall identifier, and the planning unit plans an elevator taking path between the horizontal registration position and the elevator waiting hall corresponding to the waiting hall identifier. In this case, the mobile terminal further includes:

[0118] A reminding unit for reminding the reserved elevator taking passenger;

[0119] When the judgment unit monitors that the reserved elevator taking passenger deviates from the current elevator taking path, the reminding unit reminds the reserved elevator taking passenger that the elevator waiting hall currently going to is not the correct one; if the reserved elevator taking passenger adjusts to the correct elevator taking path, it is followed according to the original elevator taking path; if the reserved elevator taking passenger insists on not returning to the correct elevator taking path, the planning unit re-plans the elevator taking path to the original correct elevator waiting hall according to the current position of the reserved elevator taking passenger, and the reminding unit informs the reserved elevator taking passenger of the re-planning result, or the planning unit re-selects the best elevator waiting hall relative to the current position according to the current position and plans the corresponding elevator taking path, and the reminding unit informs the reserved elevator taking passenger; when the elevator waiting hall is changed, the judgment unit modifies the waiting hall information in the original elevator call signal.

[0120] If the reserved elevator taking passenger does not go to any elevator waiting hall, the judgment unit cancels the elevator call signal and identifies that the reserved elevator taking passenger is maliciously calling the elevator. Alternatively, warning information is further generated and informed to the passenger by the reminding unit.

[0121] The elevator side part counts the same direction effective call signals of the same departure floor of the elevator, generates and sends a call instruction to the elevator control system if there is at least one effective call signal, and cancels all call signals of the elevator in the direction of the departure floor otherwise, the effective call signal being a call signal of a reservation passenger going to the elevator hall.

[0122] Further, the terminal position can further include a vertical position of the mobile terminal between different floors of a building where the elevator is located. On this basis, the mobile terminal further includes a verification unit for verifying whether the floor where the current position of the reservation passenger is consistent with the departure floor, and informing the passenger when the floor is inconsistent with the departure floor.

[0123] The embodiment monitors the mobile terminal after the reservation passenger registers, and sends a call signal to the elevator side part only when the mobile terminal is located on a passenger path from the registered position to the elevator hall, and generates a corresponding instruction to the elevator control system by the elevator side part, so that the disadvantages of possible misregistration in the prior art can be overcome, the elevator operation efficiency can be improved by avoiding the waste of operation capacity due to the response to invalid passenger requests, and the situation of misregistration of call signals can be eliminated.

[0124] Embodiment two

[0125] On the basis of embodiment one, the embodiment adds a limitation on the passenger conditions.

[0126] Specifically, the passenger conditions further include that the mobile terminal moves along the passenger path to the elevator hall and / or the mobile terminal is located in a segment of the passenger path close to the elevator hall, which is divided by a given point. Wherein, the given point makes the segment of the passenger path close to the elevator hall meet at least one of the following conditions:

[0127] Condition 1, the length of the segment of the passenger path close to the elevator hall is less than a length threshold;

[0128] Condition 2, the time for the reservation passenger to move from the given point to the elevator hall along the passenger path is less than a time threshold;

[0129] Condition 3, the segment of the passenger path close to the elevator hall can only lead to the elevator hall;

[0130] Condition 4, the time for the reservation passenger to move from the given point to the elevator hall along the passenger path is less than the car moving time for the elevator car to move from the current position to the departure floor.

[0131] There are two ways for the judgment unit to judge whether the mobile terminal moves along the passenger path to the elevator hall:

[0132] In the first way, the judging unit monitors whether the mobile terminal is located in the elevator path at at least two different time instants. When the mobile terminal is located in the elevator path at all time instants, and there are at least two different specific points, and the order of the specific points in time sequence is consistent with the order of the positions of the mobile terminal in the elevator path from the horizontal registration position to the elevator lobby, the judging unit determines that the mobile terminal moves along the elevator path to the elevator lobby, wherein the specific point is the point in the elevator path with the minimum distance between the terminal position currently output by the positioning unit, and the minimum distance is the minimum value of the distances between the terminal position currently output by the positioning unit and each point in the elevator path.

[0133] In the second way, the judging unit monitors whether the mobile terminal is located in the elevator path at at least two different time instants. When the mobile terminal is located in the elevator path at all time instants, and the distance between the terminal position output by the positioning unit and the elevator lobby at the later time instant is shorter than the distance between the terminal position output by the positioning unit and the elevator lobby at the earlier time instant, the judging unit determines that the mobile terminal moves along the elevator path to the elevator lobby.

[0134] Specifically, the judging unit determines whether the mobile terminal moves along the elevator path to the elevator lobby by the following steps:

[0135] Step t1, selecting a length parameter β of a time window, wherein the parameter β is such that the time window includes at least two time instants;

[0136] Step t2, determining the terminal positions output by the positioning unit corresponding to at least two time instants within the time window;

[0137] Step t3, sorting the terminal positions according to the time sequence of the time instants corresponding to the terminal positions;

[0138] Step t4, if the sorting result is consistent with the direction of the elevator path from the horizontal registration position to the elevator lobby, determining that the mobile terminal moves along the elevator path to the elevator lobby, otherwise, determining that the mobile terminal does not move along the elevator path to the elevator lobby.

[0139] There are two ways for the judging unit to determine whether the mobile terminal is located in the part of the elevator path close to the elevator lobby, which is divided into two parts by a given point:

[0140] In the first mode, when the specific point is a point in a section of the elevator waiting path close to the elevator lobby among two sections of the elevator waiting path divided by the given point, and the distance between the specific point and the terminal position output by the positioning unit is the minimum distance among distances between the terminal position output by the positioning unit and each point in the elevator waiting path, the judging unit determines that the mobile terminal is located in the section of the elevator waiting path close to the elevator lobby among two sections of the elevator waiting path divided by the given point.

[0141] In the second mode, when the mobile terminal is located in the elevator waiting path and the length of the elevator waiting path between the terminal position output by the positioning unit and the elevator lobby is shorter than the length of the elevator waiting path between the given point and the elevator lobby, the judging unit determines that the mobile terminal is located in the section of the elevator waiting path close to the elevator lobby among two sections of the elevator waiting path divided by the given point, and the specific point is a point in the elevator waiting path with the minimum distance between the terminal position output by the positioning unit and each point in the elevator waiting path.

[0142] The embodiment further limits the elevator waiting condition, and the mobile terminal sends an instruction to the elevator control system only when the reserved elevator waiting passenger is located in the elevator waiting path and moves towards the elevator lobby.

[0143] Embodiment Three

[0144] Based on the first and second embodiments, the embodiment limits the communication between the elevator side and the mobile terminal, and limits the sending of the elevator call signal to avoid sending invalid elevator call signals.

[0145] As shown in Figure 3 The elevator side further includes:

[0146] An estimating unit estimates the car moving time required for the elevator car to move from the current position to the departure floor according to the elevator operation information.

[0147] An elevator side sending unit sends the car moving time to the mobile terminal.

[0148] On this basis, the mobile terminal further includes:

[0149] A sending time determining unit determines the sending time at which the terminal sending unit sends the elevator call signal to the elevator side.

[0150] When the judgment unit judges that the boarding condition is established, the terminal sending unit sends the call signal to the elevator side part at the sending time.

[0151] The sending time determining unit determines the sending time in one of the following two ways:

[0152] Way 1, the sending time determining unit estimates the moving distance of the pre-boarding passenger within the car moving time, then takes a position obtained by moving the end point of the boarding path in the direction of the horizontal registration position by the moving distance or a certain point before the position as a specific point, and takes the time when the pre-boarding passenger reaches the specific point as the sending time.

[0153] Way 2, the sending time determining unit estimates and monitors the passenger moving time required for the pre-boarding passenger to move from the terminal position currently output by the positioning unit to the elevator lobby, and takes the time when the difference between the passenger moving time and the car moving time is equal to a time difference threshold as the sending time.

[0154] Embodiment Four

[0155] On the basis of Embodiment One, this embodiment adds a function of reminding the pre-boarding passenger to start boarding.

[0156] Specifically, the planning unit estimates the time required for the pre-boarding passenger to move from the terminal position currently output by the positioning unit to the elevator lobby according to the length of the boarding path, and determines a specific time using the time and the pre-boarding time, so that the time when the pre-boarding passenger reaches the elevator lobby after starting boarding no later than the specific time is no later than the pre-boarding time. On this basis, the mobile terminal further comprises:

[0157] The reminding unit sends a prompt to the pre-boarding passenger to remind him to start boarding after reaching the specific time or a time that is ahead of the specific time by a specified time length.

[0158] The judgment unit monitors whether the pre-boarding passenger starts boarding immediately and whether the mobile terminal moves along the boarding path to the elevator lobby, and judges that the boarding is malicious call when the judgment result is no. When the judgment unit monitors that the pre-boarding passenger makes a malicious call, the call signal registered by the pre-boarding passenger is cancelled, or further, warning information is generated and informed to the passenger by the reminding unit.

[0159] The elevator side part counts the same direction effective call signals of the same departure floor of the elevator, generates and sends a call instruction to the elevator control system if there is at least one effective call signal, otherwise cancels all call signals of the elevator in the direction of the departure floor, and the effective call signal is a call signal of a reserved passenger going to the elevator hall.

[0160] Preferably, the planning unit re-plans the elevator call path at a certain time before the specific time or at a certain interval after the registration of the call signal using the current terminal position, estimates the time for the reserved passenger to move from the current position of the mobile terminal to the elevator hall according to the new elevator call path, and re-determines the specific time.

[0161] Further, if the current terminal position from the positioning unit changes relative to the registered position, the planning unit re-plans the elevator call path according to the changed current terminal position, adjusts the specific time and / or the departure floor of the reserved passenger, and modifies the call signal.

[0162] Embodiment Five

[0163] Based on Embodiment Two, this embodiment further describes the case where there are multiple elevator halls in the building where the elevator is located.

[0164] Specifically, when the building where the elevator is located contains multiple elevator halls, the mobile terminal further comprises:

[0165] The selection unit selects one of the multiple elevator halls as the elevator hall for the planning unit to plan the elevator call path and informs the reserved passenger of the selection result.

[0166] Preferably, the selection unit selects the elevator hall closest to the reserved passenger, or requests and receives elevator operation information from the elevator side part, and selects the elevator hall with the least number of reserved passengers according to the elevator operation information.

[0167] When the selection unit changes the originally selected elevator hall, the judgment unit determines whether the reserved passenger will take the elevator according to the judgment result of the elevator call condition, and informs the reserved passenger of the changed selected elevator hall when the reserved passenger will take the elevator.

[0168] Further, the mobile terminal further comprises a reminding unit for reminding the reserved passenger.

[0169] When the judging unit monitors that the reserved elevator passenger deviates from the current elevator path, the reminding unit reminds the reserved elevator passenger that the current elevator lobby is not the correct one; if the reserved elevator passenger adjusts to the correct elevator path, the original elevator path is followed; if the reserved elevator passenger insists on not returning to the correct elevator path, the planning unit re-plans the elevator path to the original correct elevator lobby according to the current position of the reserved elevator passenger, and the reminding unit informs the reserved elevator passenger of the re-planning result, or the planning unit re-selects the best elevator lobby relative to the current position and plans the corresponding elevator path according to the current position, and the reminding unit informs the reserved elevator passenger; when the elevator lobby is changed, the judging unit modifies the lobby information in the original call signal.

[0170] If the reserved elevator passenger does not go to any elevator lobby, the judging unit cancels the call signal and determines that the reserved elevator passenger is maliciously calling the elevator. When the judging unit monitors that the reserved elevator passenger is maliciously calling the elevator, the call signal registered by the reserved elevator passenger is cancelled, or further warning information is generated and informed to the passenger by the reminding unit.

[0171] The elevator side part counts the valid call signals in the same direction of the same departure floor of the elevator, and if there is at least one valid call signal, generates and sends a call instruction to the elevator control system, otherwise cancels all call signals of the elevator in the direction of the departure floor, and the valid call signal is the reserved elevator passenger going to the elevator lobby.

[0172] Embodiment six

[0173] Considering that the reserved elevator passenger may leave the current floor (i.e. the registered floor) after reserving the call, and directly go to the elevator from the current floor where he / she is not reserved at the reserved elevator time, instead of returning to the registered floor, which will cause the current departure floor of the reserved elevator passenger to be inconsistent with the reserved departure floor when going to the elevator. Therefore, based on embodiment one, this embodiment describes the case that the reserved elevator passenger goes to other places after registering the call signal.

[0174] The terminal position further comprises a vertical position of the mobile terminal in the building where the elevator is located;

[0175] The registered position further comprises a registered floor, which refers to the floor where the reserved elevator passenger is located in the building where the elevator is located when registering the call signal.

[0176] In this case, the elevator condition further comprises:

[0177] Condition A, the reserved elevator passenger is located at the registered floor;

[0178] When the judging unit determines that the condition A is established, the terminal sending unit sends the call signal to the elevator side part, otherwise the judging unit determines that the reservation passenger modifies the departure floor of the call signal to the current floor when going to the elevator hall of the current floor, and the terminal sending unit sends the modified call signal to the elevator side part. At this time, the mobile terminal further comprises a reminding unit for informing the reservation passenger of the modified call signal.

[0179] The above has carried on the detailed explanation to the application through the specific embodiment, the above embodiment is only the preferred embodiment of the application, the application is not limited to the above implementation. Equivalent substitutions and improvements made by those skilled in the art without departing from the principles of the application should be considered within the scope of the application.
