Description

[Technical field]

[0001] The present invention relates to a remote monitoring system for an elevator. [Background technology]

[0002] In conventional elevator remote monitoring systems, when a person becomes trapped in the elevator car, the intercom and camera installed inside the car are connected to a remote monitoring device via a general public line, and the user in the car is contacted using voice and camera images. After confirming the user's safety, the elevator equipment is restored via remote control.

[0003] Patent Document 1 describes an elevator emergency notification system that enables users to make an emergency call to an operator at the elevator service center when they become trapped in the elevator car, and that enables an emergency response message to be sent from a remote monitoring computer to a user's mobile device that has an emergency notification application pre-installed.

[0004] Patent Document 2 describes a remote monitoring system in which a two-dimensional code containing access information to a remote monitoring device is attached inside the car, and when the two-dimensional code is read by a mobile terminal in an emergency, guidance information for checking the situation is sent from the monitoring device inside the remote monitoring device to the mobile terminal. Patent Document 3 describes an emergency reporting device for an elevator that displays reporting information to be reported to a remote monitoring device on a display device inside the car only if reporting processing from the reporting device is not successful within a predetermined number of retries, with the aim of preventing tampering during normal operation of the elevator.

[0006] In elevator systems, it may be difficult to invest in cameras and communication equipment for camera images. In such elevator systems, the situation inside the elevator car and the users when they are trapped cannot be determined, making it difficult to confirm safety, which can be problematic when attempting remote rescue.

[0007] An object of the present invention is to provide a remote monitoring system that enables remote rescue in the event of entrapment in an elevator apparatus that is not equipped with a camera or communication equipment for camera images. [Means for solving the problem]

[0008] The elevator remote monitoring system of the present invention comprises an elevator device, a remote monitoring device that monitors the elevator device, and has a call registration function using a mobile terminal. The elevator device comprises a monitoring device that transmits entrapment information to the remote monitoring device when it detects that a car is entrapped, and the remote monitoring device is configured to store the call registration information when it receives elevator call registration information, store the entrapment information when it receives entrapment information, and compare the call registration information with the entrapment information when it receives a connection request from the mobile terminal, and if it determines that the mobile terminal is in a location where the entrapment has occurred, communicate using the camera function of the mobile terminal.

[0009] The call registration information includes elevator information where the call registration was made and information on the call registration date and time, and the locked-in information includes elevator information where the lock-in occurred and information on the lock-in occurrence date and time, and the remote monitoring device is preferably configured to determine that the mobile terminal is in the location where the lock-in occurred when the elevator information where the call registration was made and the elevator information where the lock-in occurred match and the call registration date and time and the lock-in occurrence date and time are within a specified time period.

[0010] It is preferable that the call registration information further includes information of the mobile terminal, and when the remote monitoring device does not receive a connection request from the mobile terminal until a predetermined time has elapsed since receiving the lock-in information and the lock-in continues, it is configured to establish a communication connection to the mobile terminal recorded in the call registration information which matches the elevator information in which the lock-in occurred and the elevator information in which the call registration was made.

[0011] An elevator remote monitoring system may be configured such that a two-dimensional code recording connection information for communication connection to a remote monitoring device is installed inside the car, and when a communication connection request is made from an unregistered mobile terminal using information from the two-dimensional code, the remote monitoring device compares the elevator information in which the two-dimensional code is installed with the locked-in information, and when the unregistered mobile terminal is in the location where the lock-in has occurred and the lock-in continues, it establishes a communication connection to the unregistered mobile terminal using its camera function. Effect of the Invention

[0012] According to the present invention, a remote monitoring system capable of remotely rescuing an occupant who is trapped inside an elevator apparatus that is not equipped with a camera or communication equipment for camera images can be constructed. [Brief description of the drawings]

[0014] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, specific shapes, directions, values, etc. are examples for facilitating understanding of the present invention, and can be appropriately changed according to the application, purpose, specifications, etc. In addition, it is assumed from the beginning that the components of the embodiment and modified examples described below can be selectively combined.

[0015] In cases where building maintenance fees are kept relatively low, such as in developing countries, elevator systems are often not equipped with cameras and communication equipment for camera images as described above. In such elevator systems, the conditions inside the elevator car and the users when a person is trapped cannot be seen, making it impossible to confirm safety, which poses a problem when conducting remote rescue operations.

[0016] On the other hand, the penetration rate of mobile devices such as smartphones is high in developing countries, and various services using mobile devices can be developed in the same way as in Japan. One service using mobile devices is the elevator call registration function, which calls the elevator car to the desired floor and automatically operates to the pre-registered destination floor.

[0017] The call registration function is such that, when an elevator user approaches an elevator hall carrying a mobile terminal with a dedicated application (hereinafter referred to as the call registration application) installed, the elevator communicates with a beacon installed at the hall, calls the elevator car to the floor to be used, sets the destination floor registered in advance, and automatically drives the elevator to the destination floor. Note that the detection of the mobile terminal is not limited to a beacon, and may be configured to use a GPS (Global Positioning System).

[0018] The elevator remote monitoring system of the present invention takes advantage of the widespread use of mobile devices and utilizes the call registration function of mobile devices carried by elevator users to provide a remote monitoring system that enables remote rescue in the event that someone becomes trapped in an elevator.

[0019] First Embodiment 1 is a configuration diagram of an elevator remote monitoring system 1 according to the first embodiment. The elevator remote monitoring system 1 according to the present embodiment has a call registration function.

[0020] The remote monitoring system 1 comprises an elevator apparatus 10 and a remote monitoring device 20. The elevator apparatus 10 comprises a car 11 that rises and falls in a hoistway, and landings 12 installed on each floor. The elevator apparatus 10 further comprises a control device 13 at the top of the hoistway that controls the rise and fall of the car 11, and a monitoring device 14 that monitors for malfunctions of the car 11 and transmits entrapment information when it detects entrapment. The remote monitoring device 20 is installed in a remote monitoring center. The remote monitoring device 20 is composed of a computer or the like that is capable of communicating with the monitoring device 14 of the elevator apparatus 10. It should be noted that the remote monitoring system 1 may comprise multiple elevator apparatuses 10.

[0021] The control device 13 is connected to the monitoring device 14, the in-car operation panel 15A, the hall operation panel 15B, etc. via signal lines, and transmits and receives signals for operating the car 11. The control device 13 controls the car 11 in response to instructions from the buttons on the in-car operation panel 15A and the hall operation panel 15B. The control device 13 also controls the car 11 in response to a call for the car 11 by the call registration function from the monitoring device 14 and instructions for the destination floor.

[0022] The monitoring device 14 is configured to communicate with the remote monitoring device 20. The monitoring device 14 receives the contents of the call registration from the remote monitoring device 20 and transmits instructions to the control device 13. Furthermore, the monitoring device 14 has a function of detecting entrapment in the elevator device 10. Entrapment is detected, for example, by detecting an abnormality in the stopping position of the car 11 or an abnormality in the door of the hall 12 or the door of the car 11. When the monitoring device 14 detects the occurrence of entrapment, it transmits entrapment occurrence information to the remote monitoring device 20.

[0023] The hall operating panel 15B includes an elevator call button and a display unit for the current position of the car 11. The hall operating panel 15B lights up the corresponding button in response to a call by the call registration function and an instruction of a destination floor. The hall operating panel 15B includes a beacon 16 for the call registration function.

[0024] The mobile terminal 30 detects the beacon 16 when a user carrying the mobile terminal 30 approaches the hall 12. The mobile terminal 30 communicates with the remote monitoring device 20 and transmits information such as the use floor and destination floor linked to the beacon 16 registered in the call registration application (hereinafter referred to as call registration information). The remote monitoring device 20 transmits the call registration information to the monitoring device 14. The call registration application has a button (contact button) for communicating a rescue request (hereinafter referred to as a connection request) to the remote monitoring device 20 in the event of an emergency such as being trapped inside. The call registration application is installed in advance in the mobile terminal 30 of this embodiment.

[0025] The remote monitoring device 20 stores the call registration information received from the mobile terminal 30. The remote monitoring device 20, the monitoring device 14, and the control device 13 cooperate to move the car 11 to the service floor and the destination floor based on the call registration information.

[0026] The remote monitoring device 20 stores the lock-in information when it receives the lock-in information from the monitoring device 14. When the remote monitoring device 20 receives a connection request from the mobile terminal 30, the remote monitoring device 20 compares the call registration information with the lock-in information, and is configured to perform communication using the camera function of the mobile terminal 30 if it determines that the mobile terminal 30 is in the location where the lock-in has occurred.

[0027] The call registration information includes elevator information on which the call registration was performed, information on the date and time of the call registration, and information on the mobile terminal on which the call registration was performed. The elevator information on which the call registration was performed includes the name (number, etc.) of the building in which the elevator is installed and the car. The information on the mobile terminal on which the call registration was performed includes, for example, information such as a telephone number for connecting to the mobile terminal.

[0028] The trapped-in information includes elevator information on the elevator where the trapped-in occurred and information on the date on which the trapped-in occurred. The elevator information on the elevator where the trapped-in occurred includes the name (number, etc.) of the building in which the elevator is installed and the car.

[0029] When the remote monitoring device 20 receives a connection request from the mobile terminal 30, it compares the call registration information with the lock-in information, and if the elevator information in which the call was registered matches the elevator information in which the lock-in occurred, and the call registration date and time and the lock-in date and time are within a predetermined time period, it determines that the mobile terminal 30 is in the location where the lock-in occurred.

[0030] In addition, when the remote monitoring device 20 does not receive a connection request from the mobile terminal 30 until a predetermined time has elapsed since receiving the lock-in information and the lock-in continues, it may be configured to establish a communication connection to the mobile terminal 30 that has made a call registration recorded in the call registration information that matches the elevator information in which the lock-in occurred and the elevator information in which the call registration was made.

[0031] A two-dimensional code 17 including connection information for communication connection to the remote monitoring device 20 may be displayed inside the car. In Fig. 1, the two-dimensional code 17 is displayed below the in-car operation panel 15A. By reading the two-dimensional code 17 with a call registration application and making a connection request, the mobile terminal 30 and the remote monitoring device 20 can communicate with each other. However, the two-dimensional code 17 is merely an example, and it is sufficient if it shows information for communication with the remote monitoring device 20, and it may simply display a telephone number.

[0032] <Monitoring device> FIG. 2 shows a block diagram of the monitoring device 14 provided in the elevator system 10 of this embodiment. The monitoring device 14 is mainly composed of a computer. The functions of the monitoring device 14 are realized by this computer executing a program. The monitoring device 14 mainly comprises a CPU 141 that operates according to the program, a RAM 142 that is used as a primary storage device when executing the program, a ROM 143 in which the program and the like are stored, a communication unit 144 that transmits and receives signals to and from the control device 13 and the like, and a wireless communication unit 145 that transmits and receives signals to and from the remote monitoring device 20, as hardware components. The devices of the monitoring device 14 transmit and receive data to and from each other via a bus interface 146.

[0033] <Remote monitoring device> FIG. 3 shows a block diagram of the remote monitoring device 20 of this embodiment. The remote monitoring device 20 is also mainly composed of a computer, and the functions of the remote monitoring device 20 are realized by the computer executing a program. The remote monitoring device 20 mainly includes a CPU 201 that operates according to a program, a RAM 202 that is used as a primary storage device when executing the program of the remote monitoring device, a ROM 203 in which the program and the like are stored, a storage device 204 for storing call registration information, locked-in information, and the like, and a wireless communication unit 205 that transmits and receives signals to and from the monitoring device 14 of the elevator device 10, as hardware configurations. The wireless communication unit 205 is also configured to be able to communicate with the mobile terminal 30 carried by the elevator user. Each device of the remote monitoring device 20 transmits and receives data to and from each other via a bus interface 208. The remote monitoring device 20 may also include an input unit 206 and a display unit 207 for direct operation by an operator.

[0034] <Mobile device> 4 shows a block diagram of the mobile terminal 30 in the remote monitoring system 1 of this embodiment. The mobile terminal 30 is also mainly composed of a computer. The mobile terminal 30 includes a CPU 301 that operates according to a program, a RAM 302 that is used as a primary storage device when executing the program of the mobile terminal 30, a ROM 303 in which the basic program of the mobile terminal 30 and the like are stored, a storage device 304 that stores various application programs and data of the mobile terminal 30, a camera unit 305 for capturing images or videos, an operation unit 306 for issuing various instructions to the mobile terminal 30, a display unit 307 for displaying the operation results, and a wireless communication unit 308 for transmitting and receiving data to and from an external wireless communication device. Each device of the mobile terminal 30 transmits and receives data to and from each other via a bus interface 309.

[0035] The call registration application of this embodiment operates in cooperation with the basic control program of the mobile terminal 30. The call registration application is stored in the storage device 304, and is read into the RAM 302 and executed.

[0036] In this embodiment, the camera unit 305 is used when communication is performed using the camera function of the mobile terminal 30.

[0037] The wireless communication unit 308 is configured to be able to communicate with the remote monitoring device 20. When a call registration is performed by the mobile terminal 30, the wireless communication unit 308 transmits call registration information to the remote monitoring device 20. The wireless communication unit 308 is also used for a connection request to the remote monitoring device 20 when a person is locked in.

[0038] <Call registration information> FIG. 5 shows an example of the configuration of the call registration information. When a call registration user registers the elevator's desired floor and destination floor using the call registration application on the mobile terminal 30, the call registration information is transmitted to and stored in the remote monitoring device 20. As described above, the call registration information includes elevator information on which the call registration was performed, information on the date and time when the call registration was performed, and information on the mobile terminal that performed the call registration. The elevator information in the call registration information includes, for example, the name (number, etc.) of the building in which the elevator is installed and the car. The mobile terminal information in the call registration information includes, for example, the phone number of the mobile terminal. The mobile terminal information stored in the call registration information is used for communication with a user in the car who has become trapped.

[0039] <Confinement Information> An example of the configuration of the confinement information is shown in Fig. 6. The confinement information has elevator information in which the confinement occurred and information on the date and time of the confinement. The elevator information in the confinement information includes the name (number, etc.) of the building in which the elevator in which the confinement occurred is installed and the car.

[0040] The call registration information and the locked-in information are used by the remote monitoring device 20 to determine whether or not a user is in the car 11 where the locked-in occurred. Specifically, the remote monitoring device 20 compares the elevator information where the locked-in occurred with the elevator information where the call registration was performed. If both are the same elevator, the remote monitoring device 20 calculates the difference in time from the date and time of the call registration to the date and time of the locked-in occurred. If the calculated value is within a predetermined time, it is determined that the mobile terminal 30 stored in the call registration information is in the car 11 where the locked-in occurred, and that the user carrying the mobile terminal 30 is in the car 11 where the locked-in occurred. Here, the predetermined time is determined according to the average time required from the use floor of the elevator to the destination floor. For example, if the locked-in occurred within several minutes to ten minutes from the date and time of the call registration, it can be considered that the locked-in occurred when the car 11 according to the call registration was being operated. Therefore, in this case, it can be determined that the mobile terminal 30 stored in the call registration information is in the car 11 where the locked-in occurred, and that the user carrying the mobile terminal 30 is in the car 11 where the locked-in occurred. Note that the predetermined time is an example, and may be changed for each location where the elevator is installed. Furthermore, even for the same elevator, the predetermined time may be changed according to the usage situation.

[0041] <Specific actions for remote rescue> A specific operation of the remote rescue in the first embodiment will be described with reference to the state transition diagram in Fig. 7. In this embodiment, a person is trapped in an elevator while registering a call for the elevator.

[0042] First, when an elevator user performs call registration using the mobile terminal 30 (T1), call registration information is sent from the mobile terminal 30 to the remote monitoring device 20 (T2). The remote monitoring device 20 stores the call registration information in the storage device 204 (T3).

[0043] Based on the contents of the call registration information, the remote monitoring device 20 instructs the corresponding elevator monitoring device 14 to operate the elevator (T4).

[0044] The monitoring device 14, which has received the operation instruction of the call registration, moves the car 11 to the desired floor via the control device 13. When a user gets into the car 11, the car 11 moves to the destination floor.

[0045] Now consider the case where a trapped-in fault occurs in the elevator while a call registration is being performed (T5). The monitoring device 14 detects the trapped-in fault (T6), and if the trapped-in fault allows remote rescue, transmits information about the occurrence of the trapped-in fault (hereinafter referred to as a trapped-in report) to the remote monitoring device 20 (T7). A trapped-in fault allowing remote rescue refers to a state in which the elevator has stopped due to a discrepancy in the internal status between devices such as the control device 13. In this case, the internal status between devices can be made to match and the trapped-in fault can be resolved by resetting the power supply of the control device 13 and the power system from the remote monitoring device 20 via the monitoring device 14. The reason why the trapped-in fault is not immediately resolved by remote operation when remote rescue is possible is to ensure the safety of the users in the car 11.

[0046] The remote monitoring device 20 that has received the confinement notification stores the elevator information (information on the building and the car, etc.) in which the confinement occurred and the date and time when the confinement occurred as confinement information (T8).

[0047] Next, a user in the cage 11 where the lock-in occurred operates the contact button of the call registration application installed on the mobile terminal 30 (T9), and a connection request is made to the remote monitoring device 20 (T10). The remote monitoring device 20 that receives the connection request compares the call registration information with the lock-in information (T11). If the comparison is successful, the remote monitoring device 20 establishes a communication connection using the camera function with the mobile terminal 30 that made the connection request (T12).

[0048] Here, the comparison between the call registration information and the locked-in information will be described using the call registration information in FIG. 5 and the locked-in information in FIG. 6 as examples. The second elevator information in the call registration information in FIG. 5 and the second elevator information in the locked-in information in FIG. 6 are the same for A Building No. 1. When the remote monitoring device 20 receives elevator information of locked-in information of A Building No. 1, the remote monitoring device 20 compares the contents of the call registration information whose elevator information is A Building No. 1 from the call registration information. By comparing the second call registration date and time "YYYY Year MM Month H2 Hour M2 Minute S2 Second" of the call registration information in FIG. 5 with the second lock-in occurrence date and time "YYYY Year MM Month H2 Hour M5 Minute S5 Second" of the lock-in information in FIG. 6, if it is within a predetermined time, it is determined that the smartphone A, which is the mobile terminal that has registered the call in A Building No. 1, is in A Building No. 1, where the lock-in occurred, and the comparison is OK.

[0049] The operator of the remote monitoring device 20 communicates with the user in the car 11 using the camera function of the mobile terminal 30 (T13), confirms the situation inside the car 11, and after confirming safety, performs remote rescue (T14, T15). Remote rescue mainly involves resetting the power supply to the control device 13 and the power system. Alternatively, if the car 11 is stopped due to an object being caught in the door, the camera of the mobile terminal 30 may be used to confirm that the user has moved away from the door of the car 11, and an operation may be performed to slightly loosen the door of the car 11.

[0050] After confirming that the confinement has been resolved (T16), the remote monitoring device 20 cuts off communication with the mobile terminal 30 (T17). After that, the remote monitoring device 20 deletes the confinement information from the storage device 204 (T18).

[0051] The elevator remote monitoring system 1 of this embodiment is configured to, upon receiving a connection request from the mobile terminal 30 via a call registration application, compare the call registration information with the locked-in information, and if it is determined that the mobile terminal 30 is in a location where a lock-in has occurred, perform communication using the camera function of the mobile terminal 30. Therefore, by utilizing the camera function of the mobile terminal 30 of a user who has registered a call, it is possible to construct a remote monitoring system 1 that is capable of remote rescue in the event of a lock-in, even for an elevator device 10 that is not equipped with a camera or communication equipment for camera images.

[0052] <Second embodiment> The second embodiment will be described with reference to the state transition diagram of Fig. 8. This embodiment differs from the first embodiment in that no connection request is made by a user in a cage 11 in which confinement has occurred.

[0053] The state transition from the operation (T1) in which the elevator user first performs a call registration operation using the mobile terminal 30 to the operation (T8) in which the remote monitoring device 20 stores the locked-in information is the same as in the first embodiment.

[0054] In the second embodiment, the connection request (T9, T10) from the user in the car 11 in the first embodiment is not made.

[0055] In this embodiment, the remote monitoring device 20 counts the passage of a predetermined time when it receives a lock-in notification (T7) and registers the lock-in information (T8). If there is no connection request until the predetermined time has elapsed since the lock-in notification and the lock-in continues (T100), the remote monitoring device 20 establishes a communication connection with the mobile terminal 30 stored in the call registration information whose elevator information in the lock-in information where the lock-in has occurred matches the elevator information in the call registration (T12). The state transitions (T13 to T18) after the communication connection is established between the remote monitoring device 20 and the mobile terminal 30 are the same as those in the first embodiment, and therefore will not be described.

[0056] In this embodiment, a case where a connection request is not made by a user in the cage 11 until a predetermined time has elapsed since the occurrence of the confinement may be a situation in which the user is confused by the confinement and is unable to make a connection request. In such a case, by establishing a communication connection from the remote monitoring device 20 to the mobile terminal 30, the presence of the user in the cage 11 can be confirmed and the confinement can be safely restored. The reason for waiting until the predetermined time has elapsed is that the confinement may be restored by a power reset or the like performed by the manager of the building where the confinement occurred.

[0057] The elevator remote monitoring system 1 of this embodiment is configured to perform a communication connection to the mobile terminal 30 stored in the call registration information where the elevator information in the locked-in information matches the elevator information in the call registration information, when a connection request is not received from the mobile terminal 30 via the call registration application until a predetermined time has elapsed and the locked-in state continues. Therefore, even in a situation where a user is confused and cannot make a connection request, the remote monitoring device 20 can actively perform a communication connection to the user in the car 11 where the lock-in has occurred, confirm the status of the lock-in state, and perform a remote rescue.

[0058] <Third embodiment> The third embodiment will be described with reference to the state transition diagram in Fig. 9. This embodiment differs from the first and second embodiments in that elevator users do not register calls. Therefore, the remote monitoring device 20 does not have call registration information that has elevator information that matches the elevator information in the confinement information, and therefore cannot determine whether or not a user is in the car 11 where the confinement has occurred.

[0059] In this embodiment, the monitoring device 14 detects a confinement failure (T6), and if the confinement failure is capable of remote rescue, transmits a confinement notification to the remote monitoring device 20 (T7), and the remote monitoring device 20 stores the confinement information (T8), which are the same operations as in the first and second embodiments.

[0060] A user in the cage 11 in which the entrapment has occurred can read the two-dimensional code 17 placed in the cage 11 using a call registration application installed on a mobile terminal 30, and make a connection request to the remote monitoring device 20 using the connection information stored in the two-dimensional code 17 (T200, T201).

[0061] The two-dimensional code 17 in this embodiment stores connection information for making a connection request from the call registration application to the remote monitoring device 20. The connection request is preferably configured to include elevator information in which the two-dimensional code 17 is installed, i.e., information on the building in which the car 11 is installed and the car 11. For example, when making a connection request using the two-dimensional code 17, it is possible to configure the communication header to include information on the building and the car 11, but this is not limited to this. It is also possible to configure the two-dimensional code 17 to include different telephone number information for each building and car 11 in which the two-dimensional code 17 is installed, so that the elevator information can be identified by the receiving telephone number.

[0062] The remote monitoring device 20, which has received the connection request (T201) by the two-dimensional code 17, acquires information about the elevator in which the two-dimensional code 17 is installed.

[0063] Next, the remote monitoring device 20 checks whether or not a person is trapped by comparing the elevator information obtained by the connection request using the two-dimensional code 17 with the elevator information in the locked-in information (T202). The reason for checking whether or not a person is trapped is that a connection request may be made by mistake by reading the two-dimensional code 17 of a car 11 in which no person is locked.

[0064] When a trapped-in occurrence is confirmed from the elevator information obtained by the connection request using the two-dimensional code 17, the remote monitoring device 20 establishes a communication connection with the mobile terminal 30 that requested the connection (T12). The subsequent state transitions (T13 to T18) are similar to those in the first and second embodiments, and therefore will not be described.

[0065] The elevator remote monitoring system 1 of this embodiment is configured so that a connection request can be made from a call registration application of a mobile terminal 30 that has not registered a call, using the two-dimensional code 17 displayed inside the car 11. Therefore, elevator information on the car 11 can be obtained by a connection request using the two-dimensional code 17, and by comparing this with trapped-in information, it can be determined whether the mobile terminal 30 is in a location where a person is trapped.

[0066] As described above, according to the present invention, a remote monitoring system can be constructed that uses the camera function of the elevator user's mobile device to enable remote rescue in the event of entrapment in an elevator device that is not equipped with a camera or communication equipment for camera images.

[0067] It should be noted that the present invention is not limited to the above-described embodiment and its modified examples, and various modifications and improvements are possible within the scope of the matters described in the claims of this application. [Explanation of symbols]
