Description
This application is based on Japanese patent application 2016-. This application incorporates by reference the entirety of this application.
Technical Field
An embodiment of the present invention relates to an elevator system that makes an emergency notification from inside a car of an elevator.
Background
When an elevator is stopped in an emergency due to an earthquake, a power failure, or the like, a so-called "car-inside-trapped-accident" in which passengers are trapped inside a car may occur. In such a case, by pressing an emergency call button provided in the car, it is possible to communicate with the outside. The outside is a disaster prevention center in a building or a monitoring center of an elevator.
The "disaster prevention center in a building" is a device in which functions of a central control room are integrated, and is a device for monitoring and controlling various devices in a building including an elevator. The "monitoring center of an elevator" is a monitoring facility located at a remote place, and is used for remotely monitoring the operation state of the elevator in each building. In either case, a monitor or an operator is resident, and the call is handled when an emergency call is made from a passenger in the car.
However, in general, a disaster prevention center deals with emergency calls by 1 telephone. Therefore, for example, when a plurality of elevators are brought into emergency stop and an emergency call button is pressed in each car, a call is placed in a standby state. Similarly, even in a monitoring center where a plurality of operators reside, when an emergency call is reported in each building due to a large-scale disaster such as an earthquake, the operator cannot immediately respond to the emergency call, and thus the operator is in a state of waiting for a call.
As described above, when a plurality of elevators are brought into emergency stop and a plurality of trapped accidents occur, even if the emergency call button in the car is pressed, the state of waiting for a call may continue. Therefore, passengers in the car are uneasy to be rescued, and delay may occur in rescue.
Disclosure of Invention
The present invention addresses the problem of providing an elevator system that can reliably notify the outside of a situation in which passengers in a car are trapped when an elevator is brought to an emergency stop.
An elevator system according to one embodiment is an elevator system for performing an emergency notification using a portable terminal held by a passenger in a car, and includes a wireless signal device that is provided in the car and transmits a wireless signal when the elevator system is stopped in an emergency. An emergency notification application installed in advance in the portable terminal is activated by a wireless signal transmitted from the wireless signal device, and is connected to an external monitoring center set as a notification destination in advance, thereby notifying that the passenger is in a trapped state in the car.
According to the elevator system configured as described above, when the elevator is stopped in an emergency, it is possible to reliably notify the outside that passengers in the car are in a trapped state.

When the emergency call button 12a is pressed for several seconds, the telephone line is connected to the outside (here, the monitoring center 14), and a call can be made with the operator.
The elevator control device 13 is also referred to as a "control panel". The elevator control device 13 is provided in a machine room, not shown, provided in the uppermost part of the building 10 or in an upper part of a hoistway, and performs control of the entire elevator including operation control of the car 12. The elevator control device 13 is connected to an external monitoring center 14 via a communication network 15. The communication network 15 includes a public line network or a private line.
The monitoring center 14 is remotely located. The monitoring center 14 displays various signals (operation state information) transmitted from elevators of buildings, not shown, on a monitoring screen or the like, and, when some abnormality is detected, deals with the situation by dispatching a maintenance worker approaching the site, or the like. There are a plurality of maintenance crews at the offices in each region. Each maintenance worker holds the maintenance terminal 16 and regularly checks the buildings in the jurisdiction area to perform maintenance work. Further, there is a department called a "service information center" at the monitoring center 14. In the "service information center", an operator responds to an inquiry from a customer, a passenger, or the like in each building.
In the example of fig. 1, only the maintenance terminal 16 of one maintenance worker is illustrated, but actually, a plurality of maintenance workers each hold the maintenance terminal 16. In reality, the elevators 11 (elevator control devices 13) of a plurality of buildings are also connected to the monitoring center 14 via the communication network 15. The maintenance terminal 16 is a terminal device dedicated to maintenance and repair. The maintenance terminal 16 includes a function for maintenance and inspection in addition to various functions of a general portable terminal such as a telephone function and an email function.
In the present embodiment, a wireless signal device 21, for example, made of Bluetooth (registered trademark) or the like, is provided in the car 12. The wireless signal device 21 is used as an in-car beacon (beacon) and transmits a wireless signal of a predetermined frequency band. The installation location of the wireless signal device 21 is, for example, a ceiling surface in the car 12, but is not particularly limited thereto, and may be any location as long as a wireless signal can reach the portable terminal 22 held by a passenger in the car 12. The wireless signalling device 21 is connected to the elevator control 13 and is normally closed. When the elevator 11 (car 12) is stopped in an emergency, the wireless signal device 21 is turned on in response to an instruction from the elevator control device 13, and transmits a wireless signal of a predetermined frequency band.
The portable terminal 22 held by the passenger is a general portable telephone, a smartphone, or the like. The mobile terminal 22 is provided with an application program 20 for emergency notification. The application 20 is automatically started when the portable terminal 22 receives the wireless signal transmitted from the wireless signal device 21. By the activation of the application 20, the monitoring center 14 set as a notification destination in advance is connected, and an emergency notification is transmitted from the portable terminal 22 to the monitoring center 14.
The application program 20 for emergency notification is developed by a company related to the elevator 11, and can be freely downloaded from a Web site dependent on the os (operating system) of the portable terminal 22.
A display/broadcast device 23 is provided at a predetermined position in the car 12. The display/broadcast device 23 is connected to the elevator control device 13, and transmits some messages to passengers in the car 12 by display and sound.
The parenthesized numerals and arrows in the drawing indicate the flow of various signals and information, (1) emergency stop signal, (2) radio signal, (3) emergency report, (4) rescue request, (5) report, (6) report, and (7) display/broadcast information.
Fig. 2 is a block diagram showing the structure of the elevator control device 13.
The elevator control device 13 includes a communication unit 17 and a control unit 18. In the example of fig. 2, the communication unit 17 and the control unit 18 are provided in the elevator control device 13, but the communication unit 17 may be provided independently of the elevator control device 13.
The communication unit 17 performs communication processing with the outside via the communication network 15. The control unit 18 is a part that executes various processes necessary for the operation of the elevator 11 by starting a program, and here, includes an abnormality detection unit 18a and a notification unit 18 b.
The abnormality detection unit 18a detects a state in which the elevator 11 is brought into emergency stop due to, for example, an earthquake, a power failure, or the like, and outputs an emergency stop signal to the wireless signal device 21 in the car 12. The notification unit 18b outputs display/broadcast information for notifying passengers in the car 12 that the maintenance worker is going for rescue to the display/broadcast device 23 in the car 12.
Fig. 3 is a diagram showing an example of the external configuration of the mobile terminal 22.
The passenger mobile terminal 22 is, for example, a mobile phone, a smartphone, or the like, and is configured by a small-sized terminal device having a communication function. The above-described emergency notification application 20 is installed in the mobile terminal 22.
In the figure, 22a is an icon showing the case where the application program 20 is installed. A wireless signal of a predetermined frequency band is transmitted from a wireless signal device (beacon) 21 provided in the car 12 at the time of emergency stop. When the portable terminal 22 receives the wireless signal, the application 20 starts up to notify the monitoring center 14 of an emergency.
Fig. 4 is a block diagram showing a functional configuration of the mobile terminal 22.
The portable terminal 22 held by the passenger includes an input unit 31, a display unit 32, a control unit 33, an audio input/output unit 34, a storage unit 35, a gps (global Positioning system) module 36, a communication unit 37, an imaging unit 38, and the like.
The input unit 31 is configured by various keys, buttons, and the like, and inputs and instructs data. The display unit 32 is constituted by, for example, an LCD, and displays data.

The communication unit 37 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) and Wi-Fi. The imaging unit 38 is constituted by a digital camera capable of taking still images and moving images, and is commonly used as a camera function.
The maintenance terminal 16 held by the maintenance person also has a configuration of a general mobile phone or a smartphone, similar to the passenger's mobile terminal 22.
Fig. 5 is a block diagram showing the configuration of the monitoring center 14.
The monitoring center 14 is provided with a Web server 41 and a plurality of PCs 42a, 42b, and 42c … …. The Web server 41 exists as a control device of the monitoring center 14, and is connected to the elevator control device 13 of the elevator 11 via the communication network 15.
The PCs 42a, 42b, and 42c … … are connected to the Web server 41 via a communication line 43 such as a lan (local Area network). The PCs 42a, 42b, and 42c … … are terminal devices used by the respective operators as monitoring stations.
Fig. 6 is a block diagram showing a configuration of a Web server provided in a monitoring center.
The Web server 41 includes a control unit 51, a storage unit 52, various databases 53, a communication unit 54, and an interface (I/F) 55.
The control unit 51 is constituted by a CPU, and reads the program 52a stored in the storage unit 52 to execute various processes. The control unit 51 is provided with an emergency notification response unit 51a and a rescue request unit 51b as functional units for realizing the present system.
The emergency notification response section 51a responds to the emergency notification transmitted from the portable terminal 22 of the passenger due to the activation of the application 20. The rescue request unit 51b specifies a place where passengers are trapped, and searches for at least one maintenance worker located near the place to make a rescue request.
The storage unit 52 is configured by a storage device such as a ROM or a RAM, and stores various data necessary for processing by the control unit 51, such as a program 52 a.
On the other hand, the various databases 53 provided in the Web server 41 include a building database (building DB)53a, a maintenance database (maintenance DB)53b, a map database (map DB)53c, and the like. These databases 53a to 53c are actually provided in the storage unit 52 and the like.
The building database 53a stores information related to each building. Specifically, as shown in fig. 7, an identification number (building ID), a building name, an address, the number of elevators installed in the building, and machine number information of each building are stored.
The maintainer database 53b stores information relating to each maintainer. Specifically, as shown in fig. 8, the identification number (maintainer ID), name, affiliation (office), information (terminal ID, address, telephone number, etc.) of the portable terminal held by the maintainer, current position, attribute information, status information, etc. of the maintainer during the maintenance are stored.
In addition, the "current position" is detected by using the GPS function provided in the mobile terminal. The "attribute information" includes the career of the maintenance worker. The profession is generally classified into a "serviceman" who is mainly a general periodic maintenance and a "legal inspector" who is qualified as a legal inspection. Legal inspectors can compromise the service of the maintainer, but the number of people is generally less than that of the maintainer. The "state information" is information indicating the work state of the maintenance worker, and includes "during work", "during movement", and the like.
The map database 53c stores map information (image information) of each region. Specifically, a plurality of pieces of map information are stored in a sorted manner according to the reduction rate.
The communication unit 54 provided in the Web server 41 transmits and receives data to and from the elevator control devices 13 of the respective buildings via the communication network 15. The communication unit 54 also performs communication processing with the maintenance terminal 16 of the maintenance person and the portable terminal 22 of the passenger shown in fig. 1. The interface 55 performs data input/output processing with the PCs 42a, 42b, and 42c … … connected to the Web server 41.
Next, the operation of the present system will be described.
Fig. 9 and 10 are flowcharts for explaining the flow of the present system at the time of emergency stop. Fig. 9 mainly shows processing on the elevator 11 side, and fig. 10 mainly shows processing on the monitoring center 14 side.
It is assumed that the portable terminal 22 of the passenger riding in the car 12 is installed with the application 20 for emergency notification in advance. The portable terminal 22 also has a function of receiving a radio signal of a predetermined frequency band transmitted from the radio signal device 21 installed in the car 12.
As shown in the flowchart of fig. 9, in the normal operation state, the wireless signal device 21 provided in the car 12 is turned off. Here, when the elevator 11 (car 12) is brought into emergency stop due to, for example, an earthquake, a power failure, or the like (yes in step S11), the radio signal device 21 is turned on in response to the emergency stop signal output from the elevator control device 13 (step S12).
When the radio signal device 21 is turned on, a radio signal of a predetermined frequency band is transmitted (step S13). When the mobile terminal 22 receives the radio signal (yes in step S14), the application 20 is started (step S15), and first, the display unit 32 of the mobile terminal 22 displays the confirmation screen 61 as shown in fig. 11 (step S16). For example, since the door can be opened and closed when the car 12 is stopped at an arbitrary floor in an emergency, a trapped accident does not occur. On the other hand, when the car 12 is stopped in an emergency at a middle of each floor during movement, the door cannot be opened and closed, and passengers are trapped in the car 12. In this case, the passenger presses the yes button 61a provided on the confirmation screen 61 to select the trapped state.
When the trapped state is selected (yes in step S17), the portable terminal 22 is connected to the external monitoring center 14 via a public line network (not shown) (step S18), and notifies that the passenger is in the trapped state in the car 12 (step S19). At this time, the setting information transmitted from the wireless signal device 21 is transmitted to the monitoring center 14 via the portable terminal 22. The installation information includes at least address information of a building in which the elevator 11 is installed, identification information of the car 12, and the like.
As shown in the flowchart of fig. 10, in the Web server 41 provided in the monitoring center 14, when a notification of the trapped state (a trapped state report) is received from the portable terminal 22 of the passenger (yes at step S21), the following response processing is executed.
That is, first, the Web server 41 searches the building database 53a of fig. 7 based on the installation information transmitted from the mobile terminal 22 to specify the location (building and car) where the passenger is trapped (step S22).
When the location is determined, the Web server 41 retrieves at least one serviceman located near the location from the serviceman database 53b in fig. 8, and requests the service terminal 16 held by the serviceman for rescue (step S23). Further, as a method of requesting rescue, for example, there are the following methods: an e-mail describing the location (building and car) where the passenger is trapped is transmitted to the maintenance terminal 16 held by the maintenance person and the person goes to the site.
When there is a response from the maintenance person, the Web server 41 notifies the portable terminal 22 held by the passenger that the maintenance person is going for rescue (step S24). As a result, a notification screen 62 as shown in fig. 12, for example, is displayed on the display unit 32 of the mobile terminal 22.
Further, the Web server 41 notifies the elevator control device 13 of the elevator 11 obtained from the building information that the serviceman is going to rescue via the communication network 15 (step S25). Thus, the elevator control device 13 notifies the passengers that the maintenance worker is going for rescue by displaying a message and broadcasting a voice through the display/broadcasting device 23 in the car 12 (step S26). Fig. 13 shows an example of the message screen 63. Here, the notification is performed by both of the display message and the audio broadcast, but only either one may be used.
As described above, according to embodiment 1, when a passenger is trapped in the car 12, an emergency notification (trapping report) can be transmitted to the external monitoring center 14 by using the portable terminal 22 held by the passenger without pressing the emergency call button 12 a. In this case, the application 20 for emergency notification needs to be installed in the portable terminal 22 in advance, but the application 20 can be freely downloaded without charge, and therefore, the passenger is not burdened. As the elevator equipment, the wireless signal device 21 as a beacon may be provided at any position in the car 12, and the emergency call system can be realized by an inexpensive configuration.
In addition, normally, when the emergency call button 12a in the car 12 is pressed, the telephone line communicates with the "service information center" section in the monitoring center 14, and a call can be made with the operator. However, since the number of operators is limited, when a plurality of elevators are brought to emergency stop at the same time and emergency calls are concentrated, the operators cannot immediately deal with the emergency calls and need to wait.
In contrast, in the present system, since the passenger's portable terminal 22 is automatically connected to the monitoring center 14, there is an advantage that the presence of the trapped state can be reliably notified without intervention of an operator. After the notification, the monitoring center 14 notifies the maintenance person that the maintenance person is going for rescue through the passenger's portable terminal 22 and the display/broadcast device 23 in the car 12. Therefore, the passenger is not disturbed, and the trapped accident can be dealt with.
In the above-described embodiment 1, for example, even when a security center is present in the building 10, an emergency call is transmitted from the passenger's portable terminal 22 to the monitoring center 14 (see (3) of fig. 1). At this time, the monitoring center 14 notifies the passenger's portable terminal 22 of the response (see (7) of fig. 1), and contacts the security center of the occurrence of the trapped accident.
(embodiment 2)
Next, embodiment 2 will be explained.
For example, when a wide-range disaster such as an earthquake occurs, there is a possibility that the public line network cannot be used due to damage of the base station and concentration of telephone lines. In embodiment 2, in consideration of such a communication situation, the portable terminal 22 in the car 12 is connected to the external monitoring center 14 by a dedicated line.
Fig. 14 is a diagram showing a configuration of an elevator system according to embodiment 2. The same components as those in fig. 1 of embodiment 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.
In embodiment 2, an Access Point (AP)24 is provided in the car 12. The access point 24 is a device for constituting a wireless LAN (Wi-Fi), and is connected to a monitoring apparatus 25a of a disaster prevention center 25 provided in the building 10. The monitoring device 25a monitors various devices in the building 10 including the devices of the elevator 11, and is connected to the external monitoring center 14 through a not-shown dedicated line.
Note that the parenthesized numerals and arrows in the drawing indicate the flow of various signals and information, and like the above-described embodiment 1, (1) an emergency stop signal, (2) a radio signal, (3) an emergency report, (4) a rescue request, (5) a report, (6) a report, and (7) display and broadcast information.
In such a configuration, as in embodiment 1, for example, when the elevator 11 (car 12) is brought into emergency stop due to an earthquake, a power failure, or the like, the radio signal device 21 is turned on in response to an emergency stop signal output from the elevator control device 13, and a radio signal of a predetermined frequency band is transmitted. The emergency notification application 20 installed in advance in the mobile terminal 22 is activated by the radio signal, and whether or not the mobile terminal is in a trapped state can be confirmed on a confirmation screen 61 as shown in fig. 11, for example.
In embodiment 2, when the trapped state is selected, the portable terminal 22 is connected to the external monitoring center 14 via the access point 24 in the car 12 and the monitoring device 25a of the disaster prevention center 25. In order to connect the mobile terminal 22 to the access point 24, an authentication procedure using an ID and a password is required. The information of the ID and the password is included in the wireless signal transmitted from the wireless signal device 21. Alternatively, for example, an ID or a password may be attached to an arbitrary portion in the car 12, and the passenger may be subjected to the authentication procedure every time.
The subsequent processing is the same as in embodiment 1.
That is, the monitoring center 14 is notified of the situation in which the passenger is in the trapped state from the portable terminal 22. At this time, the installation information (address information of the building, car identification information, etc.) transmitted from the wireless signal device 21 is transmitted to the monitoring center 14. Thus, the Web server 41 of the monitoring center 14 searches for and dispatches a maintenance worker present near the site. The Web server 41 notifies the portable terminal 22 of the passenger that the maintenance person is going for rescue, and causes the display/broadcast device 23 in the car 12 to perform the same notification via the elevator control device 13.
As described above, according to embodiment 2, when the application 20 of the portable terminal 22 is started based on the wireless signal transmitted from the wireless signal device 21 in the car 12, the monitoring center 14 is connected via the access point 24 in the car 12 and the monitoring device 25a of the disaster prevention center 25. In this case, the monitoring device 25a of the disaster prevention center 25 is connected to the monitoring center 14 through a dedicated line. Therefore, even in a state where the portable terminal 22 cannot use a public line network, which is a general telephone line, the monitoring center 14 can be reliably notified of the presence of the trapped state.
(embodiment 3)
Next, embodiment 3 will be explained.
In the above-described embodiment 1, the wireless signal device 21 provided in the car 12 is a signal transmission device called a "beacon". In recent years, a new beacon having not only a function of transmitting a radio signal but also a function of receiving a radio signal has been developed. In embodiment 3, a radio signal device including such a new beacon is used.
Fig. 15 is a diagram showing a configuration of an elevator system according to embodiment 3. The same components as those in fig. 1 of embodiment 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.
In embodiment 3, a wireless signal device 26 formed of a new beacon is installed in the car 12. The wireless signal device 26 has a function of transmitting a wireless signal of a predetermined frequency band and receiving a wireless signal of the same frequency band.
Note that the parenthesized numerals and arrows in the drawing indicate the flow of various signals and information, and like the above-described embodiment 1, (1) an emergency stop signal, (2) a radio signal, (3) an emergency report, (4) a rescue request, (5) a report, (6) a report, and (7) display and broadcast information.
In such a configuration, as in embodiment 1, for example, when the elevator 11 (car 12) is brought into emergency stop due to an earthquake, a power failure, or the like, the radio signal device 26 is turned on in response to an emergency stop signal output from the elevator control device 13, and a radio signal of a predetermined frequency band is transmitted. The emergency notification application 20 installed in advance in the mobile terminal 22 is activated by the radio signal, and whether or not the mobile terminal is in a trapped state can be confirmed on a confirmation screen 61 as shown in fig. 11, for example.
In embodiment 3, when the trapped state is selected, the portable terminal 22 is connected to the external monitoring center 14 via the wireless signal device 26 and the elevator control device 13, and notifies that the passenger is in the trapped state in the car 12. At this time, the installation information (address information of the building, car identification information, etc.) transmitted from the wireless signal device 21 is transmitted to the monitoring center 14.
The subsequent processing is the same as in embodiment 1.
That is, the Web server 41 of the monitoring center 14 searches for and dispatches a maintenance person present near the site. The Web server 41 notifies the portable terminal 22 of the passenger that the maintenance person is going for rescue, and causes the display/broadcast device 23 in the car 12 to perform the same notification via the elevator control device 13.
As described above, according to embodiment 3, when the application 20 of the portable terminal 22 is started based on the wireless signal transmitted from the wireless signal device 26 in the car 12, the monitoring center 14 is connected via the wireless signal device 26 and the elevator control device 13. In this case, the elevator control device 13 can be connected to the monitoring center 14 via a dedicated line included in the communication network 15. Therefore, even in a state where the portable terminal 22 cannot use a public line network, which is a general telephone line, the monitoring center 14 can be reliably notified of the presence of the trapped state.
Further, since the wireless signal device 26 has a signal receiving function, it is not necessary to provide the access point 24 as in embodiment 2 above in the car 12, and accordingly, the facility cost can be reduced.
In embodiment 3, for example, even when a security center is present in the building 10, an emergency call is transmitted from the passenger's portable terminal 22 to the monitoring center 14 via the elevator control device 13 (see (3) of fig. 15). At this time, the elevator control device 13 receives a response from the monitoring center 14, and notifies the display/broadcast device 23 in the car 12 (see (7) of fig. 15), and also communicates the occurrence of the trapped accident to the security center.
According to at least one embodiment described above, it is possible to provide an elevator system capable of reliably notifying the outside of a situation in which passengers in a car are trapped when an elevator is brought to an emergency stop.
In the above embodiments, when an emergency call is reported from the passenger's portable terminal 22, the notification is made to both the portable terminal 22 and the display/broadcast device 23, but the notification may be made to either one of them.
In the above embodiments, if the nationality of the passenger is registered in advance as personal information in the portable terminal 22, the application program 20 can also notify the passenger of the nationality in a language corresponding to the nationality of the passenger by reading the personal information from the portable terminal 22 and transmitting the personal information to the monitoring center 14 when the application program is activated. Specifically, for example, when it is determined that the nationality is china from the personal information of the passenger, the confirmation screen 61 shown in fig. 11 is displayed in chinese. Further, the notification screen 62 shown in fig. 12 and the display message screen 63 shown in fig. 13 are also displayed in chinese, and sound broadcasting is performed in chinese.
Further, for example, if attribute information such as a wheelchair user is registered in the portable terminal 22, when an emergency call is made from a plurality of cars 12 at the same time, the monitoring center 14 can determine the car 12 that gives priority to a response based on the attribute information. In this case, for example, if there is a car 12 on which a wheelchair user is mounted, the rescue process is preferentially performed on the passengers in the car 12.
In addition, the installation information (address information of the building, car identification information, and the like) transmitted from the wireless signal device 21 is made to include emergency equipment information indicating whether a simple toilet or the like is always provided in the car 12. Thus, when an emergency call is made from a plurality of cars 12 at the same time, the monitoring center 14 can determine the car 12 that responds preferentially based on the emergency equipment information. In this case, if there is a car 12 without emergency equipment such as a simple toilet, for example, the rescue process is preferentially performed on the passengers in the car 12.
In short, several embodiments of the present invention have been described, and these embodiments are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the scope equivalent thereto.
