Description

Elevator system

The present application is based on japanese patent application 2020-007700 (filing date: 21 st of 2020), based on which priority is granted. This application is hereby incorporated by reference into this application, including all content of this application.

Technical Field

Embodiments of the present invention relate to an elevator system for call registration using a user's mobile terminal.

Background

In general, a hall call button for registering hall calls is provided in a hall of each floor of a building. When a user of the elevator operates a hall call button, the car responds to the registered floor of the hall call. When a user gets into the car and operates a destination floor button of a car operation panel, a destination floor is registered, and the car moves to the destination floor.

In recent years, there has been considered an elevator system in which call registration is performed by using a mobile terminal held by a user. In this case, an application software for call registration is installed in advance in a mobile terminal, and when a user arrives at a hall of an arbitrary floor, the application software is activated by using radio waves transmitted from a wireless signal device called a "beacon" to call an elevator car, and a destination floor of the user is registered in the elevator car.

Disclosure of Invention

However, in the above-described system, there is a problem that, for example, a mobile terminal is connected to a beacon provided on another floor by radio, and a hall call is erroneously registered, which is caused by radio waves. If there is such erroneous registration, the car responds needlessly, thus resulting in a decrease in the running efficiency. In addition, the user may not know that the hall call is registered in another floor by mistake and wait in the hall.

The invention provides an elevator system, which can prevent error registration caused by radio wave and accurately perform call registration in call registration of a user using a terminal device.

An elevator system according to an embodiment includes: an elevator control device for controlling the operation of the car; and a plurality of first wireless signal devices provided in each hall for each floor, for starting application software for call registration installed in advance in the mobile terminal. The mobile terminal is provided with: a storage unit for storing boarding information including a boarding floor and a destination floor of a user; a radio wave intensity measuring unit for measuring the radio wave intensity of the radio signal; and a control unit that, when a hall call registration mode is set by the activation of the application software, selects a first wireless signal device having the highest radio wave intensity among the first wireless signal devices as a connection target, and performs hall call registration processing based on the elevator riding information.

According to the elevator system having the above configuration, in the call registration by the user using the terminal device, erroneous registration due to radio waves can be prevented, and the call registration can be performed accurately.

(embodiment 1)

For example, an elevator 11 is installed in a building such as an office building. The elevator 11 includes a car 12 and an elevator control device 13. The car 12 is supported to be vertically movable on a pair of guide rails erected in the hoistway 10 (see fig. 7), and moves on each floor in response to hall calls or car calls.

The "hall call" is a call signal registered in the hall of each floor, and includes information on the registered floor and the destination direction. The "car call" refers to a call signal registered in the car room, and includes information on the destination floor. As described later, in the present system, hall calls and car calls can be registered by the mobile terminal 25 of the user, and no button operation (operation of the hall button 23 or the destination floor button 17) in the hall or in the car is required. In addition, "registration of a car call" is also referred to as "registration of a destination floor".

A car door 14 is attached to the entrance of the car 12 so as to be openable and closable, and a car operating panel 15 is provided in the vicinity of the car door 14. The car operating panel 15 is provided with various operation buttons including a destination floor button 17, a door opening button 18a, a door closing button 18b, and the like corresponding to each floor of the building, in addition to a display 16 for displaying the current position, the running direction, and the like of the car 12.

The elevator control device 13 is also called a "control panel" and is provided in an uppermost part of a building, not shown, in a machine room or an upper part of a hoistway 10 (see fig. 7), and controls the entire elevator including the operation control of the car 12.

On the other hand, in the hall 20 of each floor, a hall door 21 is attached to the entrance of the car 12 so as to be openable and closable, and a hall operating panel 22 is provided in the vicinity of the hall door 21. When the car 12 arrives, the hall doors 21 are opened and closed together with the car doors 14. The drive source (door motor) is located on the car door 14 side, and the hoistway door 21 engages with the car door 14 to perform opening and closing operations. A hall button 23 for causing the car 12 to respond to the hall 20 is provided on the hall operation panel 22. The hall button 23 is constituted by an up button and a down button for designating a destination direction of the user (constituted by only the up button at the lowermost layer and only the down button at the uppermost layer).

Here, in the present embodiment, the first wireless signal device 27 made of Bluetooth (registered trademark) or the like is provided at an arbitrary position in the hall 20. The first radio signal device 27 serves as a "hall beacon" and transmits a radio signal of a predetermined frequency band. The installation site of the first wireless signal device 27 is, for example, a wall or the like near the hall door 21, but is not particularly limited, and any place may be used as long as the wireless signal can reach the mobile terminal 25 held by the user (passenger) who arrives at the hall 20.

The first wireless signal device 27 is provided in the hall 20 including each floor of the reference floor. The first wireless signal device 27 is connected to the elevator control device 13 and the hall operating panel 22, and is turned ON all the time during operation of the elevator 11 (car 12), and has a function of transmitting information about the hall (hereinafter referred to as hall information) by radio waves in a predetermined frequency band. The hall information includes information such as a group (access), a hall floor, and the like. Further, the hall information includes building information. The building information has identification information for determining the building in which the elevator is provided.

The mobile terminal 25 held by the user is a general mobile phone, a smart phone, or the like. The mobile terminal 25 is provided with application software 26 for call registration in advance. The application software 26 for call registration is developed by an associated enterprise of the elevator 11 and can be freely downloaded from a Web site depending on the OS (Operating System) of the mobile terminal 25.

Using the application software 26, the boarding information of the user can be set for each of the plurality of buildings. The term "building" as used herein refers to a building provided with an elevator having the system. As described later, the user boarding information includes information of a group name, a boarding floor, and a destination floor for each building (see fig. 6).

The application software 26 is automatically started when the mobile terminal 25 receives a wireless signal transmitted from the first wireless signal device 27 in the lobby 20. The application software 26 has a hall call registration mode and a destination floor registration mode. When the application 26 is started, the hall call registration mode is first set. When the hall call registration mode is set, the mobile terminal 25 performs hall call registration processing by the first wireless signal device 27. When the registration of the hall call is completed, a destination floor registration mode is set.

A second wireless signal device 28, which is formed of Bluetooth (registered trademark) or the like, for example, is provided at an arbitrary position in the car 12. The second wireless signal device 28 serves as a "beacon (beacon)" for transmitting a wireless signal of a predetermined frequency band. The installation position of the second wireless signal device 28 is, for example, a wall near the car door 14, but is not particularly limited, and any place may be used as long as the wireless signal can reach the range of the mobile terminal 25 held by the user (passenger) coming to the hall 20.

The second wireless signal device 28 is connected to the elevator control device 13 and the car operating panel 15, is always ON during operation of the elevator 11 (car 12), and has a function of transmitting information (hereinafter referred to as operation information) concerning the operation state of the car 12 by radio waves in a predetermined frequency band. The traveling information of the car 12 includes a floor (hereinafter referred to as a current floor) and a destination direction of the current traveling of the car 12. When the destination floor registration mode is set, the mobile terminal 25 performs a registration process of the destination floor by the second wireless signal device 28.

Fig. 2 is a block diagram showing the configuration of the elevator control apparatus 13.

The elevator control device 13 includes a control unit 31 and a storage unit 32. The control unit 31 is a part that executes various processes necessary for the operation of the elevator 11 by the start of a program, and includes an operation control unit 31a, a car position detection unit 31b, and a door opening/closing control unit 31c.

The operation control unit 31a performs operation control of the car 12. In the present embodiment, the operation control unit 31a controls the operation of the car 12. Specifically, the operation control unit 31a causes the car 12 to respond to the boarding floor of the user based on the hall call registered in the hall, and causes the car 12 to operate based on the destination floor of the user registered in the car 12.

The car position detecting unit 31b detects the current position of the car 12. As a detection method, there is a method of calculating the current position of the car 12 or the like from a value obtained by counting pulse signals of a pulse encoder output in synchronization with the rotation of the hoisting machine, for example.

The door opening/closing control unit 31c controls the opening/closing operation of the car door 14 when the car 12 reaches the hall 20. Specifically, when the car 12 is detected to be flat in the hall 20 by a not-shown flat floor detection device, the door opening/closing control unit 31c moves the car door 14 in the door opening direction to be fully opened. After a predetermined time has elapsed, the door opening/closing control unit 31c moves the car door 14 in the door closing direction to fully close the car door. The hoistway doors 21 also move in the same direction as the car doors 14.

The storage unit 32 stores signals transmitted from the wireless signal device 27 provided in the hall 20, the wireless signal device 28 provided in the car 12, and the car operating panel 15. The transmitted signal is, for example, information of hall call (boarding floor, destination direction), information of car call (destination floor), or the like. The control unit 31 performs operation control of the car 12 based on the information stored in the storage unit 32.

Fig. 3 is a block diagram showing the configuration of the

wireless signal devices

27 and 28.

The first wireless signal device 27 and the second wireless signal device 28 have substantially the same configuration, and include a control unit 33 and a communication unit 34. The control unit 33 performs processing of a radio signal related to call registration. The communication unit 34 performs transmission/reception processing of radio signals in a predetermined frequency band.

Fig. 4 is a diagram showing an example of the external configuration of the mobile terminal 25.

The passenger's mobile terminal 25 is, for example, a mobile phone, a smart phone, or the like, and is constituted by a small-sized terminal device having a communication function. The mobile terminal 25 is provided with the application software 26 for call registration. In the figure, 25a is an icon indicating that the application software 26 is installed. As described above, when the mobile terminal 25 receives a radio signal of a prescribed frequency band from the first radio signal device 27 provided in the hall 20, the application software 26 is started.

Fig. 5 is a block diagram showing a functional configuration of the mobile terminal 25.

The mobile terminal 25 held by the passenger includes an input unit 41, a display unit 42, a control unit 43, an audio input/output unit 44, a storage unit 45, a GPS (Global Positioning System ) module 46, a communication unit 47, a radio wave intensity measuring unit 48, and the like.

The input unit 41 is configured by various keys, buttons, and the like, and performs input or instruction of data. The display unit 42 is configured by, for example, an LCD, and displays data. The input unit 41 may be configured as follows: a transparent touch panel is used to input and instruct data on the screen of the display unit 42.

The control unit 43 is configured by a CPU, and executes various functions by starting a predetermined program. The control unit 43 has a function of executing a hall call registration process and a destination floor registration process according to the call registration application software 26. The sound input/output unit 44 is constituted by a microphone for inputting sound and a speaker for outputting sound.

The storage unit 45 is configured by a storage device such as a ROM or a RAM, and stores various programs including the application software 26. The storage unit 45 is provided with a building boarding table T1.

As shown in fig. 6, the building boarding table T1 stores boarding information of users arbitrarily set for each building by using the application software 26 in advance. The boarding information includes information of the boarding floor and the destination floor of the user. The buildings a, b, and c in the figure are, for example, apartments, main buildings, branch buildings, and the like, and are each provided with an elevator that a user uses daily.

The boarding information may include a group name such as a group. For example, in a high-rise building, a plurality of car may be operated by being divided into a low-rise group and a high-rise group. The user rides the lower group of the car or the higher group of the car according to the destination floor of the user. Groups a and B in the figure are, for example, a lower layer group and an upper layer group.

The GPS module 46 is used to detect the current location. The communication unit 47 is a general-purpose interface for performing wireless communication with the outside, and can perform long-distance wireless communication using a public line network, and short-distance wireless communication such as Bluetooth (registered trademark) and Wi-Fi. The radio wave intensity measuring unit 48 measures the intensity of the radio wave transmitted from the

radio signal devices

27 and 28 shown in fig. 1.

In such a configuration, the user can register hall calls and destination floors by the wireless signal device 27 provided in the hall 20 and the wireless signal device 28 provided in the car 12, as long as the user holds the user's mobile terminal 25 to the hall 20. However, due to the use of radio waves, erroneous registration may occur due to the condition of the hall, or the like.

Hereinafter, the problem of erroneous registration and countermeasures for preventing the erroneous registration will be described in detail, which are classified into (a) the hall call registration and (b) the destination floor registration.

(a) When waiting for elevator hall call registration

False registration of hall call

Fig. 7 is a diagram for explaining a situation in which hall calls are registered by mistake. In addition, only 1 floor and 2 floors are shown here for convenience, but in practice there are more floors.

Now, using the application software 26 for call registration, it is assumed that "group names" are set in the mobile terminal 25: group A, riding stairs: 2F, destination floor: 1F "as boarding information of a user in the building a (refer to fig. 6).

In fig. 7, the beacons connectable to the mobile terminal 25 are 3 types of first wireless signal devices (hereinafter referred to as "1-floor hall beacons") 27-1 provided in the 1-floor hall 20-1, first wireless signal devices (hereinafter referred to as "2-floor hall beacons") 27-2 provided in the 2-floor hall 20-2, and second wireless signal devices (hereinafter referred to as "car-in beacons") 28 provided in the car 12.

The more obstacles, the weaker the electric wave intensities of these beacons 27-1, 27-2, 28. In the example of fig. 7, the following procedure is adopted.

2-layer elevator hall beacon > car inner beacon > 1-layer elevator hall beacon

Here, in the case where the user is located in the hall 20-2 of the floor 2, the mobile terminal 25 may receive the electric wave of the hall beacon 27-1 of the floor 1 in addition to the electric wave of the hall beacon 27-2 of the floor 2, thereby registering hall calls in both the floor 2 and the floor 1. This is because the radio wave emitted from the floor 1 beacon 27-1 may be reflected on the wall surface of the hoistway 10, etc., and the mobile terminal 25 of the user in the hall 20-2 may receive the radio wave.

[ error registration prevention countermeasure for hall call ]

Fig. 8 is a diagram for explaining a false registration prevention measure for hall call.

The application software 26 has a hall call registration mode and a destination floor registration mode, and uses "registering a destination floor in a car" after "registering a hall call in a hall" as a basic operation. In the hall call registration mode, the hall beacon is the connection target. In the destination floor registration mode, the in-car beacon is the connection target.

In order to prevent erroneous registration of hall calls, the following conditions are set in advance in the application software 26.

(1) The hall call registration mode is initially set, and only radio waves of hall beacons can be received. That is, the radio wave of the car beacon is not received.

(2) The hall beacon with the highest radio wave intensity is selected to register the hall call.

Thus, as shown in fig. 8, when the user arrives at the hall 20-2 of the floor 2, the mobile terminal 25 can register hall calls by being connected wirelessly only to the hall beacon 27-2 of the floor 2.

Fig. 9 is a flowchart showing an operation at the time of hall call registration in the elevator system according to embodiment 1, and mainly shows a process of the mobile terminal 25 (control unit 43) of the user.

Now, as shown in fig. 8, it is assumed that the user has arrived at his own boarding floor, i.e., floor 2, with the mobile terminal 25. The mobile terminal 25 is provided with application software 26 for call registration in advance. During normal operation of the elevator 11, the hall beacons 27-1 of the 1 floor and 27-2 of the 2 floors are always ON (step S11). When the operation of the elevator 11 is stopped or the control operation is being performed due to some abnormality such as a power failure, the hall beacons 27-1 and 27-2 are turned OFF by the beacon control signal outputted from the elevator control device 13.

When the hall beacon 27-1 of the floor 1 and the hall beacon 27-2 of the floor 2 are ON, radio signals of a predetermined frequency band are transmitted, respectively (step S12). When the mobile terminal 25 receives the wireless signal of the hall beacon 27-1 of the floor 1 or the hall beacon 27-2 of the floor 2 ("yes" in step S13), the application software 26 is started (step S14).

In this case, for example, a confirmation screen for confirming the presence or absence of a boarding may be displayed on the display unit 42 of the mobile terminal 25, and when the boarding intention is confirmed, call registration may be performed. This can avoid an inadvertent call registration, for example, when the user passes through only the hall 20 or goes to another floor.

With the start of the application software 26, the hall call registration mode is set first (step S15). In the hall call registration mode, the mobile terminal 25 is wirelessly connected to a hall beacon to register a hall call. The mobile terminal 25 has a function of measuring the intensity of the received radio wave (radio wave intensity measuring unit 48), and selects a hall beacon having the highest radio wave intensity as a connection target when the hall call registration mode is set. In the example of fig. 8, the user is located at 2 floors, so that the electric wave intensity of the hall beacon 27-2 at 2 floors is the highest. Accordingly, the mobile terminal 25 is wirelessly connected to the hall beacon 27-2 of the floor 2 (step S16), and the hall call of the user is registered in the hall operating panel 22-2 of the floor 2 (step S17).

Specifically, the mobile terminal 25 reads the boarding information of the user corresponding to the current building from the building boarding table T1 of fig. 6 based on the building information transmitted from the floor 2 hall beacon 27-2, and transmits the boarding information to the floor 2 hall beacon 27-2. Thereby, a downward hall call is registered in the hall operation panel 22-2 of the floor 2 via the hall beacon 27-2 of the floor 2, and transmitted to the elevator control device 13. The elevator control device 13 directs the car 12 to the hall 20-2 of the floor 2 based on the hall call.

As described above, according to embodiment 1, when the user arrives at the hall with the mobile terminal 25, the hall beacon having the highest radio wave intensity is selected as the connection target. In this case, the hall beacon having the highest radio wave intensity is a hall beacon existing in the vicinity of the user, that is, a hall beacon provided at the boarding floor of the user, and can accurately register a hall call via the hall beacon.

(b) When registering destination floor

[ mis-registration of destination floor ]

Fig. 10 is a diagram for explaining a situation in which a destination floor is erroneously registered.

In the call registration application software 26, "group name, boarding floor, destination floor" may be arbitrarily set as boarding information of the user. In addition, since the destination direction can be determined from the combination of the boarding floor and the destination floor, it is not necessary to set the destination direction. When building information is downloaded from a predetermined website to the mobile terminal 25, information on the group configuration (group configuration) of elevators, floors, and the like of the building can be obtained. By a predetermined operation, the group name, the boarding floor, and the destination floor of an elevator (car) used by a user are set as boarding information. The boarding information is stored in a building boarding table T1 shown in fig. 6 for each building.

When the destination floor registration mode is set after the hall call registration mode, the communication destination of the mobile terminal 25 becomes the in-car beacon 28. Here, if the destination floor is registered by connecting with the in-car beacon 28 in a state where the car 12 does not reach the boarding floor of the user, the registered destination floor is canceled by the "reverse call cancel function" of the elevator when the direction of the car 12 is reversed.

Describing the example of fig. 10, it is assumed that the car 12 is located at floor 1 when the destination floor registration mode is set. At this time, if the mobile terminal 25 is connected to the in-car beacon 28 and registers the destination floor of the user (here, 1F), when the car 12 reaches floor 2, the registered destination floor of the user is canceled in order to reverse the destination direction to floor 1. In this case, since the user does not register a destination floor when riding on the car 12, the destination floor button 17 of the car operating panel 15 must be operated to register a destination floor.

[ error registration prevention countermeasure for destination floor ]

Fig. 11 is a diagram for explaining a countermeasure against erroneous registration of the destination floor.

The "group name, number machine name, current floor, destination direction" is transmitted from the in-car beacon 28 as the running information of the car 12. At the in-car beacon position (1) of fig. 11, the in-car beacon 28 transmits "a-1-1-UP" as the running information. Similarly, at the in-car beacon position (2), the in-car beacon 28 transmits "A-1-2-DN" as the running information. UP is UP and DN is down.

Information about the current floor and destination direction of the car 12 can be obtained in real time from the elevator control 13. Therefore, the running information transmitted from the in-car beacon 28 is changed according to the position of the car 12.

Fig. 12 is a diagram showing comparison between boarding information of a user set by an application and operation information transmitted from the in-car beacon 28.

When the car 12 is at the 1 floor, the current floor of the car 12 transmitted from the in-car beacon 28 is "1F", which does not coincide with the boarding floor "2F" of the user. When the car 12 arrives at floor 2, the current floor of the car 12 transmitted from the in-car beacon 28 is "2F", and matches the user's boarding floor "2F". At this time, if the mobile terminal 25 is wirelessly connected to the in-car beacon 28, the destination floor "1F" of the user can be registered when the car 12 is at floor 2. Therefore, even when the direction of the car 12 is reversed and the car moves from the floor 2 to the floor 1, the destination floor "1F" is not registered.

Fig. 13 is a flowchart showing an operation at the time of destination floor registration in the elevator system according to embodiment 1, and mainly shows a process of the mobile terminal 25 (control unit 43) of the user.

Now, as shown in fig. 11, in the hall 20-2 of the floor 2, it is assumed that the user holds the mobile terminal 25 and waits for the arrival of the car 12. During normal operation of the elevator 11, the in-car beacon 28 is always ON (step S21). When the operation of the elevator 11 is stopped or the controlled operation is being performed due to some abnormality such as a power failure, the in-car beacon 28 is turned OFF by the beacon control signal output from the elevator control device 13.

When the in-car beacon 28 is ON, a radio signal of a predetermined frequency band is transmitted (step S22). When the mobile terminal 25 receives the radio signal (yes in step S23), a destination floor registration mode is set (step S24). In detail, since the hall call has already been registered in the hall call registration mode, the hall call registration mode is switched to the destination floor registration mode.

The traveling information including the current floor of the car 12 is transmitted from the in-car beacon 28. In the destination floor registration mode, the mobile terminal 25 compares the boarding information of the user set by the application with the operation information of the car 12 transmitted from the in-car beacon 28 (step S25). As shown in fig. 6, the boarding information of the user set by the application is stored in the building boarding table T1 for each building. The mobile terminal 25 reads elevator information of the user corresponding to the current building from the building elevator table T1, and compares the elevator information with the operation information transmitted from the in-car beacon 28.

Here, "group name, boarding floor, destination direction" is included in the boarding information of the user set by the application, and "group name, current floor, destination direction" is included in the running information of the car 12. If the information of the two matches (yes in step S25), the mobile terminal 25 is wirelessly connected to the in-car beacon 28 (step S26), and the destination floor of the user is registered in the car 12 (step S27).

Specifically, the mobile terminal 25 reads the boarding information of the user corresponding to the current building from the building boarding table T1 of fig. 6 based on the building information transmitted from the floor-2 hall beacon 27-2, and transmits the boarding information to the in-car beacon 28. Thus, the destination floor of the user is registered on the car operating panel 15 of the car 12 by the in-car beacon 28, and is transmitted to the elevator control device 13. The elevator control device 13 causes the user to ride on the car 12, and then causes the car 12 to travel to the destination floor of the user.

As described above, according to embodiment 1, the traveling information of the car 12 is transmitted from the car beacon 28 and compared with the boarding information of the user. Therefore, if the car 12 is connected wirelessly to the in-car beacon 28 when the travel information matches the boarding information of the user, the destination floor can be registered accurately when the car 12 reaches the boarding floor of the user, and the destination floor can be prevented from being canceled by reversing the direction.

(embodiment 2)

Next, embodiment 2 will be described.

In embodiment 2, the destination floor of the user is registered in consideration of the door opening/closing state of the car 12 at the time of registering the destination floor in (b).

[ mis-registration of destination floor ]

Fig. 14 is a diagram for explaining a situation in which a destination floor is registered by mistake.

In embodiment 1 described above, destination floors are registered when the car 12 reaches the boarding floor of the user by transmitting boarding information including the current floor of the car 12 from the in-car beacon 28. However, strictly speaking, the time when the car 12 arrives at the hall 20 and the time when the information of the in-car beacon 28 is switched deviate somewhat.

In the example of fig. 14, immediately before the car 12 reaches the floor of the user, i.e., the floor 2 (see D in the figure), the current floor of the car 12 transmitted from the in-car beacon 28 is switched from "1F" to "2F". Therefore, the destination floor is registered before the car 12 reaches the floor 2, and when the car 12 reaches the floor 2 and the direction is reversed to the floor 1, the destination floor is canceled.

[ error registration prevention countermeasure for destination floor ]

Fig. 15 is a diagram showing a relationship between door opening and closing of the car 12 and call registration.

The hall call can be registered regardless of the door opening/closing of the car 12. However, the registration of the destination floor is not possible, but is not possible when the door is "fully closed" or "in the opening of the door is started", and the door is "fully opened". The "start closing to closing" may or may not be performed to register a call.

Fig. 16 is a diagram for explaining a countermeasure against erroneous registration of the destination floor.

The operation information including door opening/closing information of the car 12 is transmitted from the car interior beacon 28. The door opening/closing information of the car 12 can be obtained in real time from the elevator control device 13. When the car 12 is connected wirelessly to the in-car beacon 28 and registers a destination floor when the user's boarding floor is fully opened, the destination floor is not canceled by reversing the direction.

At the in-car beacon position (1) of fig. 16, the in-car beacon 28 transmits "a-1-1-UP-full door closing" as the running information. Similarly, at the in-car beacon position (2), the in-car beacon 28 transmits "a-1-2-DN-full door" as the running information. The "full door" and "full door" become door opening and closing information.

Fig. 17 is a diagram showing comparison between boarding information of a user set by an application and operation information transmitted from the in-car beacon 28.

When the car 12 is at the 1 floor, the current floor of the car 12 transmitted from the in-car beacon 28 is "1F", which does not coincide with the boarding floor "2F" of the user. When the car 12 arrives at floor 2, the current floor of the car 12 transmitted from the in-car beacon 28 is "2F", and matches the user's boarding floor "2F". Here, if the destination floor of the user is registered when the car 12 is fully opened at 2 floors, the destination floor can be prevented from being canceled by reversing the direction.

Fig. 18 is a flowchart showing an operation at the time of destination floor registration in the elevator system according to embodiment 2, and mainly shows a process of the mobile terminal 25 (control unit 43) of the user. In fig. 18, the processing of steps S31 to S35 is the same as the processing of steps S21 to S25 of fig. 13.

In addition, "match with application settings" in step S35 means that "group name, boarding floor, destination direction" included in the boarding information of the user matches "group name, current floor, destination direction" included in the running information of the car 12, as in step S25 of fig. 13.

Here, when the application setting is matched (yes in step S35), the mobile terminal 25 determines whether or not the car 12 is fully opened in the boarding floor based on the door opening/closing information of the car 12 transmitted from the in-car beacon 28 (step S36). When the car 12 is fully opened in the boarding floor (yes in step S36), the mobile terminal 25 is wirelessly connected to the in-car beacon 28 (step S37), and the destination floor of the user is registered in the car 12 (step S38).

As described above, according to embodiment 2, door opening/closing information of the car 12 is transmitted from the car interior beacon 28. Therefore, if the passenger car 12 registers the destination floor when the user's boarding floor is fully opened, the destination floor can be prevented from being canceled by reversing the direction.

(embodiment 3)

Next, embodiment 3 will be described.

In embodiment 3, at the time of registering the destination floor in (b), the destination floor of the user is registered in consideration of the detection range of the in-car beacon 28.

[ mis-registration of destination floor ]

Fig. 19 is a diagram for explaining a situation in which a destination floor is erroneously registered.

The detection range of the in-car beacon 28 is preferably reduced to only the in-car (see E0 in the figure). However, in practice, for example, when the car 12 opens the door in the hall 20-2, a wide area including the hall 20-2 becomes a detection area (see E1 in the figure). Therefore, even when the user is located at a place slightly away from the car 12, for example, the destination floor is registered in advance, and the car 12 may start before the user takes a seat. In this case, since the registration process of the destination floor is completed, call registration cannot be continued, and the convenience of the application software 26 is impaired. The car 12 moves to the destination floor without the user being mounted thereon, and therefore, is not used for traveling.

[ error registration prevention countermeasure for destination floor ]

Fig. 20 is a diagram for explaining a countermeasure against erroneous registration of the destination floor.

The output of the car beacon 28 is adjusted, and the range in front of the car 12 is set as the optimal detection range E2 (E0 < E2 < E1). The mobile terminal 25 has a function of measuring the radio wave intensity (radio wave intensity measuring unit 48). As shown in fig. 21, when the radio wave intensity of the in-car beacon 28 is measured to be gradually higher, or when the radio wave intensity is measured to be equal to or higher than the threshold TH1, the destination floor can be registered when the user approaches the car 12.

Fig. 22 is a flowchart showing an operation at the time of destination floor registration in the elevator system according to embodiment 3, and mainly shows a process of the mobile terminal 25 (control unit 43) of the user.

Now, as shown in fig. 19, in the hall 20-2 of the floor 2, it is assumed that the user holds the mobile terminal 25 and waits for the car 12 to arrive. During normal operation of the elevator 11, the in-car beacon 28 is always ON (step S41), and a radio signal of a predetermined frequency band is transmitted (step S42).

Here, in embodiment 3, when the destination floor registration mode is set after the hall call registration mode (step S43), the mobile terminal 25 measures the radio wave intensity of the in-car beacon 28 (step S44). If the radio wave intensity of the in-car beacon 28 is in a tendency to gradually increase (upward tendency) (yes in step S45), it may be determined that the user is approaching the car 12 from the hall 20-2 of the floor 2 and is registering the destination floor.

However, since the user may return, it is preferable to wait until the electric wave intensity of the in-car beacon 28 becomes equal to or higher than the preset threshold TH 1. As shown in fig. 21, the threshold TH1 is set based on the radio wave intensity measured in the optimum detection range E2. This can avoid, for example, wasteful registration of the destination floor when the user returns halfway without riding the car 12.

When confirming that the radio wave intensity of the in-car beacon 28 is equal to or higher than the threshold value TH1 (yes in step S46), the mobile terminal 25 wirelessly connects to the in-car beacon 28 (step S47), and performs the destination floor registration process (step S48).

As described above, according to embodiment 3, the destination floor is registered when the radio wave intensity of the in-car beacon 28 becomes higher gradually or becomes equal to or higher than the threshold TH1, and thus the user can register when approaching the car 12. This prevents unnecessary call registration when the user is not riding on the car 12.

(embodiment 4)

Next, a fourth embodiment will be described.

In embodiment 4, in the hall call registration of (a), the hall call is registered in consideration of the detection range of the hall beacon 27.

[ erroneous registration and prevention countermeasure for hall call ]

Fig. 23 is a diagram for explaining a situation in which hall calls are registered erroneously and a countermeasure against the erroneous registration.

The user now takes the mobile terminal 25 to his own elevator hall 20-2 at the level 2 landing floor. At this time, if the detection range of the hall beacon 27-2 of the floor 2 is assumed to be E11, there is a possibility that the user registers hall call only through the detection range E11. If a hall call is registered, the car 12 will respond to the user's landing and is therefore useless. In addition, since the registration process of the hall call is completed, the call registration cannot be continued, and the convenience of the application software 26 is impaired.

Therefore, similarly to the in-car beacon 28 described in embodiment 3, the output of the hall beacon 27-2 is adjusted, and the range immediately before the hall operating panel 22 is set as the optimum detection range E12 (E12 < E11). The mobile terminal 25 has a function of measuring the intensity of the received radio wave (radio wave intensity measuring unit 48). When the radio wave intensity of the hall beacon 27-2 is measured to be gradually higher or when the threshold TH2 or more is measured, the hall call is registered, and the hall call can be registered when the user approaches the hall operating panel 22-2. The correlation of the detection range and the electric wave intensity may be the same as fig. 21.

Although the hall beacon 27-2 provided at the floor 2 is described as an example, the hall beacons at the respective floors including the hall beacon 27-1 provided at the floor 1 are similar.

Fig. 24 is a flowchart showing an operation at the time of hall call registration in the elevator system according to embodiment 4, and mainly shows a process of the mobile terminal 25 (control unit 43) of the user.

Now, as shown in fig. 23, a case is assumed in which the user arrives at the hall 20-2 with holding the mobile terminal 25. While the elevator 11 is operating normally, hall beacons 27-1 and 27-2 of the respective floors are always ON (step S51), and a radio signal of a predetermined frequency band is transmitted (step S52).

Here, in embodiment 4, when the hall call registration mode is set in response to the activation of the application software 26 (step S53), the mobile terminal 25 measures the radio wave intensity of the hall beacon 27-2 (step S54). If the radio wave intensity of the hall beacon 27-2 tends to increase (i.e., tends to rise) (yes in step S55), it is possible to determine that the user is approaching the hall operating panel 22-2 of the 2 floors and register a hall call.

However, since there is a possibility that the user returns, it is preferable to wait until the radio wave intensity of the hall beacon 27-2 becomes equal to or higher than the preset threshold TH 2. The threshold TH2 is set based on the radio wave intensity measured in the optimal detection range E12. This can avoid, for example, unnecessary registration of hall calls when the user returns halfway without riding on the car 12.

When the mobile terminal 25 confirms that the radio wave intensity of the hall beacon 27-2 is equal to or higher than the threshold value TH2 (yes in step S56), it wirelessly connects to the hall beacon 27-2 (step S57), and performs a hall call registration process (step S58).

As described above, according to embodiment 4, when the radio wave intensity of the hall beacon provided at the elevator riding floor of the user gradually increases or the state of the threshold TH2 or more is set, the hall call is registered, and the user can register when approaching the hall operation panel provided at the elevator riding floor. This prevents unnecessary call registration when the user is not riding on the car 12.

According to at least one embodiment described above, it is possible to provide an elevator system capable of preventing erroneous registration caused by radio waves and accurately performing call registration in call registration by a user using a terminal device.

In addition, although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other modes, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and their equivalents.
