Description

Elevator system

This application is based on Japanese patent application No. 2020-. This application is incorporated by reference herein in its entirety.

Technical Field

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

Background

In general, a hall call button for registering a hall call is provided in a hall at each floor of a building. When the user of the elevator operates the call button of the elevator waiting hall, the passenger car responds to the registered floor called by the elevator waiting hall. When a user gets into the car and operates the destination floor button of the car operating panel, the destination floor is registered and the car is moved to the destination floor.

In recent years, an elevator system that performs call registration using a portable terminal held by a user is considered. This is to install application software for call registration in advance in a mobile terminal, and when a user arrives at an elevator hall at an arbitrary floor, the application software is activated by using radio waves transmitted from a radio signal device called a "beacon" to call a car, and a destination floor of the user is registered in the car.

Disclosure of Invention

However, in the above-described system, a problem of erroneous registration due to radio waves, such as erroneous registration of a hall call due to wireless connection of a mobile terminal to a beacon installed on another floor, is likely to occur. If there is such a misregistration, the car responds meaninglessly, thus resulting in a decrease in the running efficiency. In addition, the user may wait at the hall without knowing that the hall call is erroneously registered on another floor.

The problem to be solved by the invention is to provide an elevator system, which can prevent error registration caused by radio wave in call registration of user using terminal device, and can correctly perform call registration.

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

According to the elevator system configured as described above, in the call registration of the user using the terminal device, erroneous registration due to radio waves can be prevented, and the call registration can be performed accurately.

The building information has identification information for determining a 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 enterprise related to the elevator 11, and can be freely downloaded from a Web site that depends on an 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 a plurality of buildings. The term "building" as used herein refers to a building provided with an elevator having the present system. As described later, the boarding information of the user includes information of a group name, boarding floors, and destination floors 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 at the lobby 20. The application software 26 has a lobby call registration mode and a destination floor registration mode. When the application software 26 is started, the hall call registration mode is first set. When the hall call registration mode is set, the mobile terminal 25 performs a registration process of a hall call 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, for example, formed of Bluetooth (registered trademark) or the like, is provided at an arbitrary position in the car 12. The second wireless signal device 28 is used as an "in-car beacon (beacon)" and transmits a wireless signal of a predetermined frequency band.

The travel information of the car 12 includes a floor (hereinafter, referred to as a current floor) on which the car 12 is currently traveling, a destination direction, and the like. When the destination floor registration mode is set, the portable terminal 25 performs a process of registering a destination floor by the second wireless signal device 28.

Fig. 2 is a block diagram showing the structure of the elevator control device 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 starting a program, and here includes an operation control unit 31a, a car position detection unit 31b, and a door opening/closing control unit 31 c.

The operation control unit 31a controls the operation 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 calls the car 12 to respond to the user's boarding floor in accordance with the hall call registered in the hall, and operates the car 12 in accordance with the user's destination floor registered in the car 12.

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

The door opening/closing control unit 31c controls the opening/closing operation of the car doors 14 when the car 12 arrives at the waiting hall 20. Specifically, when the flat-bed detection device, not shown, detects that the car 12 is flat-bed in the waiting hall 20, the door opening/closing control unit 31c moves the car door 14 in the door opening direction to fully open the car. After a predetermined time has elapsed, the door opening/closing control unit 31c moves the car doors 14 in the door closing direction to fully close the car doors. The hoistway doors 21 also move in the same direction together with the movement of 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 on a hall call (boarding floor, destination direction), information on a car call (destination floor), and the like. The control unit 31 controls the operation 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 basically 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 a radio signal of a predetermined frequency band.

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

The passenger mobile terminal 25 is, for example, a mobile phone, a smart phone, or the like, and is configured by a small 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 showing that the application software 26 is installed. As described above, when the mobile terminal 25 receives a radio signal of a predetermined frequency band from the first radio signal device 27 installed in the hall 20, the application software 26 is activated.

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

The portable 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 measurement unit 48, and the like.

The input unit 41 is configured by various keys, buttons, and the like, and inputs or instructs data. The display unit 42 is formed of, for example, an LCD, and displays data. The input unit 41 may be configured as follows, for example: data input and instruction are performed on the screen of the display unit 42 using a transparent touch panel.

The control unit 43 is constituted by a CPU, and executes various functions by starting a predetermined program. The control unit 43 has a function of executing a registration process of a hall call and a registration process of a destination floor in accordance with the application software 26 for call registration. 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. In addition, the storage unit 45 is provided with a building boarding table T1.

As shown in fig. 6, elevator boarding information of a user arbitrarily set for each building using the application software 26 in advance is stored in the building elevator boarding table T1. The boarding information includes information on the boarding floor and the destination floor of the user. The buildings a, b, and c in the drawing are, for example, residential apartments, general company buildings, branch company buildings, and the like, and are provided with elevators used by users on a daily basis.

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

The GPS module 46 is used to detect the current position. The communication unit 47 is a general-purpose interface for performing wireless communication with the outside, and is capable of performing long-distance wireless communication using a public line network and short-range wireless communication such as Bluetooth (registered trademark) or Wi-Fi. The radio wave intensity measurement 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, a user can register a hall call and a destination floor by using the wireless signal device 27 provided in the hall 20 and the wireless signal device 28 provided in the car 12 by simply carrying his/her mobile terminal 25 to the hall 20. However, since radio waves are used, there are cases where erroneous registration occurs due to the situation of the hall or the like.

Hereinafter, the problem of erroneous registration and the countermeasure for preventing the erroneous registration will be described in detail in the case of (a) call registration at a hall and (b) destination floor registration.

(a) When the call of the elevator waiting hall is registered

[ misregistration of hall calls ]

Fig. 7 is a diagram for explaining a situation in which a hall call is erroneously registered. In addition, only

floors

1 and 2 are shown here for convenience, but actually there are many more floors.

Now, using the application software 26 for call registration, it is assumed that "group name: group A, elevator-taking floors: 2F, destination floor: 1F ″ is used as boarding information of the user in the building a (see fig. 6).

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

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

2-layer waiting hall beacon > beacon in car > 1-layer waiting hall beacon

Here, when the user is located in the hall 20-2 of the 2-floor, the mobile terminal 25 may receive the radio wave of the hall beacon 27-1 of the 1-floor in addition to the radio wave of the hall beacon 27-2 of the 2-floor, and register the hall call in both the 2-floor and the 1-floor. This is because the radio wave emitted from the 1-floor beacon 27-1 may be reflected by the wall surface of the hoistway 10, and the user's mobile terminal 25 in the hall 20-2 may receive the radio wave.

[ countermeasures for preventing misregistration of hall calls ]

Fig. 8 is a diagram for explaining the countermeasures for preventing misregistration in hall calls.

The application software 26 basically operates to register a hall call in the hall and then register a destination floor in the car, and has a hall call registration mode and a destination floor registration mode. In the hall call registration mode, the hall beacon is a connection target. In the destination floor registration mode, an in-car beacon is a connection target.

In order to prevent the misregistration of the hall call, the following conditions are set in advance in the application software 26.

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

(2) And selecting the beacon with the highest radio wave intensity to register the call of the elevator waiting hall.

Thus, as shown in fig. 8, when the user arrives at the hall 20-2 at level 2, the mobile terminal 25 can wirelessly connect only to the hall beacon 27-2 at level 2 to register a hall call.

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 user's mobile terminal 25 (control unit 43).

Now, as shown in fig. 8, assume that the user has carried the mobile terminal 25 to the 2 th floor, which is the boarding floor of the user. 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 at the 1 st floor and the hall beacons 27-2 at the 2 nd floor are always ON (step S11). When the operation of the elevator 11 is stopped or a controlled operation is being performed due to some abnormality such as a power failure, the 1-floor hall beacon 27-1 and the 2-floor hall beacon 27-2 are turned OFF by the beacon control signal output from the elevator control device 13.

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

In this case, for example, a confirmation screen for confirming whether or not there is an elevator boarding may be displayed on the display unit 42 of the mobile terminal 25, and call registration may be performed when the elevator boarding intention is confirmed. This can prevent, for example, a user from inadvertently making a call registration while passing only the hall 20 or going to another floor.

With the application software 26 started, the hall call registration mode is first set (step S15). In the hall call registration mode, the mobile terminal 25 is wirelessly connected to the hall beacon to register a hall call. The mobile terminal 25 has a function of measuring the intensity of the received radio wave (a radio wave intensity measuring section 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, since the user is located at 2 floors, the radio wave intensity of the hall beacon 27-2 at 2 floors is the highest. Therefore, the mobile terminal 25 is wirelessly connected to the hall beacon 27-2 on the 2-floor (step S16), and the hall call of the user is registered in the hall operation panel 22-2 on the 2-floor (step S17).

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

As described above, according to embodiment 1, when the user arrives at the lobby while holding the mobile terminal 25, the lobby 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 installed on the boarding floor of the user, and the hall call can be accurately registered via the hall beacon.

(b) When registering the destination floor

[ mis-registration of destination floor ]

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

The application software 26 for call registration can arbitrarily set "group name, boarding floor, and destination floor" 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 the building information is downloaded from a predetermined website to the mobile terminal 25, information on the group configuration (group configuration) of the elevator of the building, the floor, and the like can be obtained. The group name, the boarding floor, and the destination floor of the elevator (car) used by the user are set as boarding information by predetermined operations. This 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 is the in-car beacon 28. Here, if the car 12 is connected to the in-car beacon 28 in a state where it does not reach the boarding floor of the user and a destination floor is registered, the registered destination floor is cancelled by the "reverse call cancellation function" of the elevator when the direction of the car 12 is reversed.

In the example of fig. 10, it is assumed that the car 12 is 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 to register the user's destination floor (here, 1F), when the car 12 arrives at the 2 th floor, the registered user's destination floor is cancelled in order to reverse the destination direction to the 1 st floor. In this case, since the user does not register the destination floor when riding in the car 12, the user must register the destination floor by operating the destination floor button 17 of the car operating panel 15.

[ preventive measures against erroneous registration of destination floor ]

Fig. 11 is a diagram for explaining the erroneous registration prevention measures for the destination floors.

The in-car beacon 28 transmits "group name, car name, current floor, destination direction" as the travel information of the car 12. In the in-car beacon position (1) of fig. 11, the in-car beacon 28 transmits "a-1-1-UP" as the travel information. Likewise, at the in-car beacon position (2), the in-car beacon 28 transmits "a-1-2-DN" as the travel information. UP is UP operation and DN is down operation.

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

Fig. 12 is a diagram comparing boarding information indicating a user who applies setting and operation information transmitted from the in-car beacon 28.

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

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

Now, as shown in fig. 11, in the hall 20-2 at level 2, it is assumed that the user holds the portable 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 wireless signal of a predetermined frequency band is transmitted (step S22). When the mobile terminal 25 receives the wireless signal (yes at step S23), a destination floor registration mode is set (step S24). Specifically, 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 in-car beacon 28 transmits operation information including the current floor of the car 12. In the destination floor registration mode, the portable terminal 25 compares the boarding information of the user to which the setting is applied and the operation information of the car 12 transmitted from the in-car beacon 28 (step S25). The user boarding information set by the application is stored in a building boarding table T1 for each building as shown in fig. 6. The mobile terminal 25 reads the boarding information of the user corresponding to the current building from the building boarding table T1, and compares the boarding information with the operation information transmitted from the in-car beacon 28.

Here, the boarding information of the user to which the setting is applied includes "group name, boarding floor, destination direction", and the travel information of the car 12 includes "group name, current floor, destination direction". If the information of both are matched (yes in step S25), the mobile terminal 25 is wirelessly connected to the in-car beacon 28 (step S26), and the user' S destination floor 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 2-story hall beacon 27-2, and transmits the boarding information to the in-car beacon 28. Thus, the user's destination floor is registered on the car operating panel 15 of the car 12 by the car-inside beacon 28, and transmitted to the elevator control device 13. The elevator control device 13 causes the user to ride in the car 12, and then causes the car 12 to travel to the user's destination floor.

In this way, according to embodiment 1, the operation information of the car 12 is transmitted from the in-car beacon 28 and compared with the boarding information of the user. Therefore, if the operation information of the car 12 matches the boarding information of the user, the destination floor can be accurately registered when the car 12 reaches the boarding floor of the user by wirelessly connecting the in-car beacon 28, and the destination floor can be prevented from being cancelled by reversing the direction.

(embodiment 2)

Next, embodiment 2 will be explained.

In embodiment 2, the destination floor of the user is registered in consideration of the door open/close state of the car 12 at the time of the destination floor registration in the above-described (b).

[ mis-registration of destination floor ]

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

In the above-described embodiment 1, the car interior beacon 28 transmits the boarding information including the current floor of the car 12, and thereby the destination floor is registered when the car 12 reaches the boarding floor of the user. However, strictly speaking, there is a little difference between the time when the car 12 arrives at the waiting hall 20 and the time when the information of the in-car beacon 28 is switched.

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

[ preventive measures against erroneous registration of 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 opening and closing of the door of the car 12. However, regarding the registration of the destination floor, "full-door-closing" and "start-to-open" are not possible, and "full-door-opening" is possible. Note that "start to close the door" may or may not allow call registration.

Fig. 16 is a diagram for explaining the erroneous registration prevention measures for the destination floors.

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

In the in-car beacon position (1) of fig. 16, the in-car beacon 28 transmits "a-1-1-UP-fully closed door" as the operation information. Likewise, at the in-car beacon position (2), the in-car beacon 28 transmits "a-1-2-DN-all-open door" as the operation information. The "fully closed door" and the "fully opened door" become door opening and closing information.

Fig. 17 is a diagram for comparing boarding information indicating a user who applies setting with operation information transmitted from the in-car beacon 28.

When the car 12 is at floor 1, the current floor of the car 12 transmitted from the in-car beacon 28 is "1F", and does not match the boarding floor "2F" of the user. When the car 12 arrives at the 2 th floor, the current floor of the car 12 transmitted from the in-car beacon 28 is "2F" and matches the boarding floor "2F" of the user. Here, if the car 12 registers the user's destination floor when the 2-floor full door is opened, it is possible to prevent the destination floor from being cancelled due to the direction reversal.

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

Similarly to step S25 in fig. 13, the phrase "match the application setting" in step S35 means that the "group name, boarding floor, and destination direction" included in the boarding information of the user matches the "group name, current floor, and destination direction" included in the travel information of the car 12.

Here, when the setting is matched with the application setting (yes in step S35), the portable terminal 25 determines whether or not the car 12 is fully opened at 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 at the boarding floor (yes at step S36), the mobile terminal 25 is wirelessly connected to the in-car beacon 28 (step S37), and the user' S destination floor is registered in the car 12 (step S38).

In this way, according to embodiment 2, the door opening/closing information of the car 12 is transmitted from the in-car beacon 28. Therefore, if the car 12 registers the destination floor when the user's boarding floor is fully opened, the destination floor can be prevented from being cancelled due to the direction reversal.

(embodiment 3)

Next, embodiment 3 will be explained.

In embodiment 3, in the destination floor registration in the above-described (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 desirably preferably narrowed to only the in-car (see E0 in the figure). However, in practice, when the car 12 opens at the hall 20-2, for example, a wide range including the hall 20-2 becomes a detection range (see E1 in the figure). Therefore, for example, even when the user is located at a place slightly away from the car 12, the destination floor is registered in advance, and there is a possibility that the car 12 departs before the user gets on the car. In this case, since the registration process of the destination floor is completed, the call registration cannot be continued, and the convenience of the application software 26 is impaired. In addition, since the car 12 moves to the destination floor without carrying a user, it is useless for traveling.

[ preventive measures against erroneous registration of destination floor ]

Fig. 20 is a diagram for explaining the erroneous registration prevention measures for the destination floors.

The output of the in-car beacon 28 is adjusted so that the range near the car 12 is the optimum detection range E2(E0 < E2 < E1). The mobile terminal 25 has a function of measuring the radio wave intensity (a radio wave intensity measuring section 48). As shown in fig. 21, if the destination floor is registered when a state in which the radio wave intensity of the in-car beacon 28 gradually increases is measured or when a state in which the radio wave intensity is not less than the threshold TH1 is measured, 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 of the elevator system according to embodiment 3, and mainly shows a process of the user's portable terminal 25 (control unit 43).

Now, as shown in fig. 19, in the hall 20-2 at level 2, it is assumed that the user holds the portable 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 S41), and transmits a radio signal of a predetermined frequency band (step S42).

In embodiment 3, when the destination floor registration mode is set after the hall call registration mode (step S43), the portable 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 of gradually increasing (ascending tendency) (yes at step S45), it may be determined that the user approaches the car 12 from the hall 20-2 at the 2 th floor and registers the destination floor.

However, since there is a possibility that the user returns, it is preferable to wait until the radio 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 optimal detection range E2. This can avoid unnecessary registration of the destination floor when the user returns halfway without riding the car 12, for example.

When it is confirmed that the radio wave intensity of the in-car beacon 28 is equal to or higher than the threshold TH1 (yes in step S46), the mobile terminal 25 wirelessly connects to the in-car beacon 28 (step S47) and performs a process of registering a destination floor (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 gradually increases or becomes equal to or higher than the threshold TH1, and thus the user can be registered when approaching the car 12. This can prevent useless call registration when the user is not riding in the car 12.

(embodiment 4)

Next, a fourth embodiment will be explained.

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

[ misregistration of hall calls and preventive measures ]

Fig. 23 is a diagram for explaining a situation in which a hall call is erroneously registered and a countermeasure for preventing the hall call.

Now, the user takes the mobile terminal 25 to his/her own elevator hall 20-2 at the 2-floor boarding floor. At this time, if the probe range of the 2-floor hall beacon 27-2 is assumed to be E11, there is a possibility that the user registers the hall call only through the probe range E11. If a hall call is registered, the car 12 is useless for responding to the boarding floor of the user. In addition, since the registration processing 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 so that the range immediately before the hall operating panel 22 is the optimum detection range E12(E12 < E11). The mobile terminal 25 has a function of measuring the intensity of the received radio wave (a radio wave intensity measuring section 48). When the hall call is registered when a state in which the radio wave intensity of the hall beacon 27-2 is gradually increased or when a state in which the threshold TH2 or more is measured, the hall call can be registered when the user approaches the hall operation panel 22-2. The correlation between the detection range and the electric wave intensity may be the same as that in fig. 21.

Although the hall beacon 27-2 installed on the 2-story floor is described as an example, the hall beacons on the respective floors including the hall beacon 27-1 installed on the 1-story floor are also 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 user's mobile terminal 25 (control unit 43).

Now, as shown in fig. 23, assume a case where the user takes the mobile terminal 25 to arrive at the lobby 20-2. During normal operation of the elevator 11, the hall beacons 27-1 and 27-2 at each floor are always ON (step S51), and a radio signal of a predetermined frequency band is transmitted (step S52).

In embodiment 4, when the hall call registration mode is set with the application software 26 activated (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 (tends to rise) (yes at step S55), it is determined that the user is approaching the hall operating panel 22-2 of level 2, and the hall call can be registered.

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 prevent, for example, a user from uselessly registering a hall call when the user returns halfway without riding 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 TH2 (yes at step S56), it is wirelessly connected to the hall beacon 27-2 (step S57), and performs a hall call registration process (step S58).

As described above, according to embodiment 4, the hall call is registered when the radio wave intensity of the hall beacon provided on the boarding floor of the user gradually increases or becomes equal to or higher than the threshold TH2, and the user can be registered when approaching the hall operating panel provided on the boarding floor. This can prevent wasteful call registration when the user is not riding in the car 12.

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