[0010] Problems to be Solved by the Invention

[0011] In an elevator device, it is sometimes very difficult to invest in equipment for cameras and camera image communication devices. In such an elevator device, since the situation inside the elevator car and the user when a trap occurs is unknown, safety confirmation cannot be performed, which becomes a problem during remote rescue.

[0012] An object of the present invention is to provide a remote monitoring system that can perform remote rescue in the event of entrapment in an elevator device that does not have a camera and a communication device for camera images.

[0013] Means for solving the problem

[0014] The remote monitoring system of the elevator of the present invention includes an elevator device and a remote monitoring device for monitoring the elevator device, and has a call registration function based on a portable terminal. The elevator device is characterized in that it has a monitoring device that, when detecting that the car is entrapped, sends the entrapment information to the remote monitoring device. The remote monitoring device is configured to: store the call registration information when receiving the call registration information of the elevator, store the entrapment information when receiving the entrapment information, and when receiving a connection request from the portable terminal, compare the call registration information and the entrapment information. When it is determined that the portable terminal is in the place where entrapment has occurred, communication using the camera function of the portable terminal is performed.

[0015] Preferably, the call registration information includes the elevator information for which call registration has been performed and the information of the call registration date and time, and the entrapment information includes the elevator information where entrapment has occurred and the information of the entrapment occurrence date and time. The remote monitoring device is configured to determine that the portable terminal is in the place where entrapment has occurred when the elevator information for which call registration has been performed is the same as the elevator information where entrapment has occurred and the call registration date and time and the entrapment occurrence date and time are within a specified time.

[0016] Preferably, the call registration information further includes information of the portable terminal. The remote monitoring device is configured to, when no connection request is received from the portable terminal within a specified time after receiving the entrapment information and the entrapment continues, perform a communication connection with the portable terminal recorded in the call registration information where the elevator information where entrapment has occurred is the same as the elevator information for which call registration has been performed.

[0017] Alternatively, the remote monitoring system of the elevator has a two-dimensional code recording connection information for performing a communication connection with the remote monitoring device in the car. The remote monitoring device is configured to, when a communication connection is requested through the information of the two-dimensional code from a portable terminal that has not performed call registration, compare the elevator information where the two-dimensional code is set with the entrapment information. When the portable terminal that has not performed call registration is in the place where entrapment has occurred and the entrapment continues, perform a communication connection using the camera function with the portable terminal that has not performed call registration.

[0018] Advantageous effects of the invention

[0019] According to the present invention, it is possible to construct a remote monitoring system that can perform remote rescue in the event of entrapment for an elevator device that does not have a camera and a communication device for camera images. Brief description of the drawings

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, specific shapes, directions, numerical values, etc. are examples for easy understanding of the present invention and can be appropriately changed according to uses, purposes, specifications, etc. In addition, it is assumed from the beginning that the structural elements of the embodiments and modified examples described below are selectively combined.

[0030] When the maintenance cost of a building is suppressed to a low level, for example, in a developing country, etc., there is a situation where a camera and a communication device for camera images are not provided in the elevator device as described above. In such an elevator device, since the conditions inside the elevator car and the users at the time of entrapment are not known, safety confirmation cannot be performed, which becomes a problem during remote rescue operations.

[0031] On the other hand, even in developing countries, the penetration rate of portable terminals represented by smartphones is relatively high, and various services that effectively utilize portable terminals can be carried out in the same way as in Japan. One of the services that effectively utilizes portable terminals has the following elevator call registration function: calling the elevator car to the floor where the user is located and automatically running to a pre-registered destination floor.

[0032] The call registration function means that when the user of the elevator approaches the landing of the elevator with a portable terminal installed with a dedicated application (hereinafter referred to as the call registration application), it communicates with the beacon set at the landing, calls the elevator car to the floor where the user is located, sets the pre-registered destination floor, and automatically runs to the destination floor. In addition, the detection of the portable terminal is not limited to using the beacon, and it can also be configured to use GPS (Global Positioning System).

[0033] Focusing on the penetration rate of portable terminals, the remote monitoring system of the elevator of the present invention provides a remote monitoring system that can effectively utilize the portable terminal held by the user of the elevator and the call registration function to perform remote rescue when a person is trapped in the elevator.

[0034] <First Embodiment>

[0035] Figure 1 It is a structural diagram of the remote monitoring system 1 of the elevator in the first embodiment. The remote monitoring system 1 of the elevator in this embodiment has a call registration function.

[0036] The remote monitoring system 1 includes an elevator device 10 and a remote monitoring device 20. The elevator device 10 includes: a car 11 that moves up and down in the hoistway; and landings 12 that are provided on each floor. The elevator device 10 further includes: a control device 13 that controls the movement of the car 11 in the upper part of the hoistway; and a monitoring device 14 that monitors the failure of the car 11 and sends a trapped information when a trap is detected. The remote monitoring device 20 is provided in a remote monitoring center. The remote monitoring device 20 is composed of a computer or the like that can communicate with the monitoring device 14 of the elevator device 10. In addition, the remote monitoring system 1 may include a plurality of elevator devices 10.

[0037] The control device 13 is connected to the monitoring device 14, the car operation panel 15A, the landing operation panel 15B, etc. through signal lines, and transmits and receives signals for operating the car 11. The control device 13 controls the car 11 according to the instructions based on the buttons of the car operation panel 15A and the landing operation panel 15B. In addition, the control device 13 controls the car 11 according to the call of the car 11 and the indication of the destination floor based on the call registration function from the monitoring device 14.

[0038] The monitoring device 14 is configured to communicate with the remote monitoring device 20. The monitoring device 14 receives the content of the elevator call registration from the remote monitoring device 20 and sends an instruction to the control device 13. Further, the monitoring device 14 has a function of detecting entrapment of the elevator device 10. The entrapment is detected, for example, by detecting an abnormality in the stop position of the car 11 or an abnormality in the doors at the landing 12 or the doors of the car 11. When the monitoring device 14 detects the occurrence of entrapment, it sends the entrapment occurrence information to the remote monitoring device 20.

[0039] The landing operation panel 15B has elevator call buttons, a display section for the current position of the car 11, etc. The landing operation panel 15B lights up the corresponding button according to the call based on the call registration function and the indication of the destination floor. The landing operation panel 15B has a beacon 16 for the call registration function.

[0040] When the user holding the portable terminal 30 approaches the landing 12, the portable terminal 30 detects the beacon 16. The portable terminal 30 communicates with the remote monitoring device 20 and sends information such as the used floor and the destination floor associated with the beacon 16 registered in the call registration application (hereinafter referred to as call registration information). The remote monitoring device 20 sends the call registration information to the monitoring device 14. The call registration application has a button (contact button) for making a rescue request communication (hereinafter referred to as a connection request) to the remote monitoring device 20 in case of an emergency such as entrapment. In addition, the portable terminal 30 of the present embodiment is pre-installed with the call registration application.

[0041] The remote monitoring device 20 stores the call registration information received from the portable terminal 30. The remote monitoring device 20, the monitoring device 14, and the control device 13 cooperate to move the car 11 to the used floor and the destination floor according to the call registration information.

[0042] When the remote monitoring device 20 receives the entrapment information from the monitoring device 14, it stores the entrapment information. The remote monitoring device 20 is configured to compare the call registration information and the entrapment information when it receives a connection request from the portable terminal 30, and perform communication using the camera function of the portable terminal 30 when it determines that the portable terminal 30 is at the place where entrapment has occurred.

[0043] The call registration information includes elevator information for which call registration has been performed, information on the call registration date and time, and information on the portable terminal that has performed the call registration. The elevator information for which call registration has been performed includes the building where the elevator is installed and the name (number, etc.) of the car. The information on the portable terminal having the call registration information for the call registration includes, for example, information such as the telephone number for communicating with the portable terminal.

[0044] The trapped information includes the elevator information where the trapping has occurred and the information on the date and time when the trapping occurred. The elevator information where the trapping has occurred includes the building where the elevator is installed and the name (number, etc.) of the car.

[0045] When the remote monitoring device 20 receives a connection request from the portable terminal 30, it compares the call registration information with the trapped information. When the elevator information for which a call has been registered is the same as the elevator information where the trapping has occurred and the call registration date and time and the trapping occurrence date and time are within a specified time, it is determined that the portable terminal 30 is at the location where the trapping has occurred.

[0046] In addition, the remote monitoring device 20 can also, when a connection request has not been received from the portable terminal 30 from the time when the trapped information is received until a specified time has elapsed and the trapping continues, establish a communication connection with the portable terminal 30 that has made a call registration and is recorded in the call registration information where the elevator information where the trapping has occurred is the same as the elevator information for which a call has been registered.

[0047] A two-dimensional code 17 including connection information for establishing a communication connection with the remote monitoring device 20 can also be displayed in the car. Figure 1 In, the two-dimensional code 17 is displayed below the car operation panel 15A. By reading the two-dimensional code 17 with the call registration application and making a connection request, the portable terminal 30 and the remote monitoring device 20 can communicate. However, the two-dimensional code 17 is only an example, and as long as the information for communicating with the remote monitoring device 20 is shown, a telephone number can also be simply displayed.

By executing a program by this computer, the functions of the monitoring device 14 are realized. The monitoring device 14 has a CPU 141 that operates according to a program, a RAM 142 that serves as a primary storage device when executing the program, a ROM 143 that stores programs, etc., a communication unit 144 that transmits and receives signals to and from the control device 13, etc., and a wireless communication unit 145 that transmits and receives signals to and from the remote monitoring device 20 as the main hardware structure. Each device of the monitoring device 14 mutually transmits and receives data through a bus interface 146.

[0050] <Remote Monitoring Device>

[0051] Figure 3A block diagram of the remote monitoring device 20 according to the present embodiment is shown. The remote monitoring device 20 is also mainly composed of a computer, and the functions of the remote monitoring device 20 are realized by executing a program on this computer. The remote monitoring device 20 has a CPU 201 that operates according to a program, a RAM 202 that serves as a primary storage device when executing the program of the remote monitoring device, a ROM 203 that stores programs and the like, a storage device 204 for storing call registration information, trapped information, etc., and a wireless communication unit 205 that transmits and receives signals to and from the monitoring device 14 of the elevator device 10, as the main hardware structure. The wireless communication unit 205 is configured to be able to communicate with the portable terminal 30 held by the elevator user. Each device of the remote monitoring device 20 transmits and receives data to and from each other through a bus interface 208. The remote monitoring device 20 may also have an input unit 206 and a display unit 207 for direct operation by an operator.

[0052] <Portable terminal>

[0053] Figure 4 A block diagram of the portable terminal 30 in the remote monitoring system 1 according to the present embodiment is shown. The portable terminal 30 is also mainly composed of a computer. The portable terminal 30 has a CPU 301 that operates according to a program, a RAM 302 that serves as a primary storage device when executing the program of the portable terminal 30, a ROM 303 that stores the basic program of the portable terminal 30 and the like, a storage device 304 that stores various application programs and data of the portable terminal 30, a camera head 305 for taking pictures or videos, an operation unit 306 for giving various instructions to the portable terminal 30, a display unit 307 for displaying 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 portable terminal 30 transmits and receives data to and from each other through a bus interface 309.

[0054] The call registration application according to the present embodiment operates in cooperation with the basic control program of the portable terminal 30. The call registration application is stored in the storage device 304, read into the RAM 302, and executed.

[0055] In the present embodiment, the camera head 305 is used when communicating using the camera function of the portable terminal 30.

[0056] The wireless communication unit 308 is configured to be able to communicate with the remote monitoring device 20. When the portable terminal 30 performs call registration, the wireless communication unit 308 sends the 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 trapped.

[0057] <Call registration information>

[0058] Figure 5An example of the structure of the call registration information is shown. When a user who has registered a call for the elevator registers the used floor and the destination floor of the elevator from the call registration application of the portable terminal 30, the call registration information is sent to the remote monitoring device 20 and stored. As described above, the call registration information has elevator information for which a call has been registered, information on the date and time when the call was registered, and information on the portable terminal that made the call registration. The elevator information in the call registration information includes, for example, the name (number, etc.) of the building and the car where the elevator is installed. The information on the portable terminal in the call registration information includes, for example, the phone number of the portable terminal. The information on the portable terminal stored in the call registration information is used for communication with the user in the trapped car.

[0059] <Entrapment information>

[0060] Figure 6 An example of the structure of the entrapment information is shown. The entrapment information has elevator information where entrapment has occurred and information on the date and time when the entrapment occurred. The elevator information in the entrapment information includes the name (number, etc.) of the building and the car where the elevator with entrapment has occurred.

[0061] The call registration information and the entrapment information are used by the remote monitoring device 20 to determine whether there is a user in the car 11 where entrapment has occurred. Specifically, the remote monitoring device 20 compares the elevator information where entrapment has occurred with the elevator information for which a call has been registered. When the two are the same elevator, the time difference from the date and time of call registration to the date and time of entrapment occurrence is calculated. When the calculated value is within the specified time, it is determined that the portable terminal 30 stored in the call registration information is in the car 11 where entrapment has occurred, and the user holding the portable terminal 30 is in the car 11 where entrapment has occurred. Here, the specified time is determined based on the average time required from the used floor of the elevator to the destination floor. For example, when entrapment occurs within a few minutes to ten minutes from the call registration date and time, it can be considered that entrapment occurred during the operation of the car 11 based on the call registration. Therefore, in this case, it can be determined that the portable terminal 30 stored in the call registration information is in the car 11 where entrapment has occurred, and the user holding the portable terminal 30 is in the car 11 where entrapment has occurred. In addition, the specified time is only an example and can be changed according to each installation location of the elevator. Furthermore, even in the same elevator, the specified time can be changed according to the usage situation.

[0062] <Specific actions of remote rescue>

[0063] Through Figure 7 The state transition diagram of shows the specific actions of remote rescue in the first embodiment. This embodiment is a case where entrapment occurs during the process of registering a call for the elevator.

[0064] First, when an elevator user registers a call for the elevator using the portable terminal 30 (T1), the call registration information is sent from the portable 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).

[0065] The remote monitoring device 20 instructs the monitoring device 14 of the corresponding elevator to operate the elevator according to the content of the call registration information (T4).

[0066] The monitoring device 14 that has received the operation instruction for call registration causes the car 11 to move to the floor where the user is located via the control device 13. When the user enters the car 11, the car 11 moves to the destination floor.

[0067] Here, consider the case where the elevator gets trapped during the call registration process (T5). The monitoring device 14 detects the trapped fault (T6). When the trapped fault can be remotely rescued, the monitoring device 14 sends the occurrence information of the trap (hereinafter referred to as the trap notification) to the remote monitoring device 20 (T7). The trapped fault being remotely rescuable means, for example, a state where the elevator stops due to an inconsistent internal state between devices such as the control device 13. In this case, from the remote monitoring device 20 via the monitoring device 14, through the reset operation of the power supply of the control device 13 and the power system, the internal state between the devices can be made consistent and the trap can be recovered. In the case where remote rescue is possible, the trap is not immediately recovered by remote operation in order to confirm the safety of the users in the car 11.

[0068] The remote monitoring device 20 that has received the trap notification stores the elevator information (such as building and car information) where the trap occurred and the date and time when the trap occurred as trap information (T8).

[0069] Next, the user in the trapped car 11 operates the contact button of the call registration application installed in the portable terminal 30 (T9) and requests a connection to the remote monitoring device 20 (T10). The remote monitoring device 20 that has received the connection request compares the call registration information with the trap information (T11). If the comparison is OK, the remote monitoring device 20 establishes a communication connection using the camera function with the portable terminal 30 that has made the connection request (T12).

[0070] Here, taking Figure 5 the call registration information and Figure 6 the trap information as an example, the comparison between the call registration information and the trap information will be described. Figure 5 the second elevator information of the call registration information and Figure 6The second elevator information of the trapped information is also the No. 1 machine in Building A. When the remote monitoring device 20 receives the trapped information with the elevator information being the No. 1 machine in Building A, it checks the content of the call registration information with the elevator information being the No. 1 machine in Building A according to the call registration information. For Figure 5 the second call registration date and time “YYYY year MM month H2 hour M2 minute S2 second” of the call registration information in Figure 6 is compared with the second trapped occurrence date and time “YYYY year MM month H2 hour M5 minute S5 second” of the trapped information in

[0071] When it is within the specified time, it is determined that the smartphone A of the portable terminal that has made a call registration for the No. 1 machine in Building A is at the No. 1 machine in Building A, which is the place where the trapping occurred, and it is set as comparison OK.

[0072] After the remote monitoring device 20 confirms the recovery from the trapped state (T16), it cuts off the communication with the portable terminal 30 (T17). Then, the remote monitoring device 20 deletes the trapped information from the storage device 204 (T18).

[0073] The remote monitoring system 1 of the elevator in this embodiment is configured to check the call registration information and the trapped information when a connection request is received from the portable terminal 30 via the call registration application, and use the camera function of the portable terminal 30 for communication when it is determined that the portable terminal 30 is at the trapped occurrence location. Therefore, the camera function of the portable terminal 30 of the user who has made a call registration is effectively utilized, and for the elevator device 10 without a camera and a communication device for camera images, a remote monitoring system 1 capable of performing remote rescue when a trap occurs can also be constructed.

[0074] <Second Embodiment>

[0075] The second embodiment is described by Figure 8 the state transition diagram. The difference between this embodiment and the first embodiment is that the connection request is not made by the user in the trapped car 11.

[0076] First, the state transition from the operation (T1) where an elevator user performs a call registration operation through the mobile terminal 30 to the operation (T8) where the remote monitoring device 20 stores the trapped information is the same as that in the first embodiment.

[0077] In the second embodiment, the connection requests (T9, T10) from the users inside the car 11 in the first embodiment are not performed.

[0078] In this embodiment, the remote monitoring device 20 receives a trapped notification (T7), and when the trapped information is registered (T8), it counts the passage of a specified time. In the case where there is no connection request and the trapping continues from the trapped notification until the specified time has passed (T100), the remote monitoring device 20 establishes a communication connection (T12) with the portable terminal 30 stored in the call registration information in which the elevator information where the trapping occurred in the trapped information is consistent with the elevator information of the call registration. Since the state transition (T13 - T18) after the communication connection is established between the remote monitoring device 20 and the portable terminal 30 is the same as that in the first embodiment, the description thereof is omitted.

[0079] Considering the situation where the user is confused due to being trapped and thus unable to make a connection request, it is the case where no connection request is made by the user inside the car 11 from the occurrence of the trapping until the specified time has passed in this embodiment. In such a case, by establishing a communication connection from the remote monitoring device 20 to the portable terminal 30, the presence of the user inside the car 11 can be confirmed, and the trapping can be safely recovered. In addition, waiting until the specified time has passed is because sometimes the power supply is reset by the building manager where the trapping occurred, etc., and the trapping is recovered.

[0080] The remote monitoring system 1 of the elevator in this embodiment is configured to establish a communication connection with the portable terminal 30 stored in the call registration information in which the elevator information of the trapped information is consistent with the elevator information of the call registration information when no connection request is received from the portable terminal 30 via the call registration application until the specified time has passed and the trapping continues. Therefore, even in a situation where the user is confused and unable to make a connection request, the remote monitoring device 20 can actively establish a communication connection with the user inside the car 11 where the trapping has occurred, confirm the situation of the trapping occurrence, and perform remote rescue.

[0081] <Third Embodiment>

[0082] The third embodiment is described by Figure 9 the state transition diagram. The difference between this embodiment and the first and second embodiments is that the elevator user does not perform a call registration. Therefore, the remote monitoring device 20 does not have call registration information with elevator information consistent with the elevator information of the trapped information, and thus cannot determine whether there is a user inside the car 11 where the trapping has occurred.

[0083] In this embodiment, the following operations are also the same as those in the first and second embodiments: The monitoring device 14 detects a trapped failure (T6), and when the trapped failure can be remotely rescued, it sends a trapped notification to the remote monitoring device 20 (T7), and the remote monitoring device 20 stores the trapped information (T8).

[0084] The user in the trapped car 11 can read the two-dimensional code 17 provided in the car 11 through the call registration application installed in the portable terminal 30, and make a connection request to the remote monitoring device 20 through the connection information stored in the two-dimensional code 17 (T200, T201).

[0085] 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. It is preferably configured that the connection request includes the elevator information where the two-dimensional code 17 is provided, that is, the building where the car 11 is provided and the information of the car 11. For example, when making a connection request through the two-dimensional code 17, it is considered that the communication header includes the information of the building and the car 11, but it is not limited thereto. It can also be configured that for each building and car 11 where the two-dimensional code 17 is set, the two-dimensional code 17 includes different telephone number information, and the elevator information can be determined by receiving the telephone number.

[0086] The remote monitoring device 20 that receives the connection request based on the two-dimensional code 17 (T201) obtains the elevator information where the two-dimensional code 17 is provided.

[0087] Next, the remote monitoring device 20 compares the elevator information obtained through the connection request based on the two-dimensional code 17 with the elevator information of the trapped information to confirm whether a trap has occurred (T202). The reason for confirming whether a trap has occurred is that sometimes the two-dimensional code 17 of the car 11 where no trap has occurred is misread and a connection request is made.

[0088] When it is confirmed that a trap has occurred for the elevator information obtained through the connection request based on the two-dimensional code 17, the remote monitoring device 20 establishes a communication connection with the portable terminal 30 that has made the connection request (T12). Since the subsequent state transitions (T13 to T18) are the same as those in the first and second embodiments, the description is omitted.

[0089] The remote monitoring system 1 of the elevator in this embodiment is configured to be able to make a connection request from the call registration application of the portable terminal 30 that has not performed call registration through the two-dimensional code 17 displayed in the car 11. Therefore, the elevator information where the car 11 is provided can be obtained through the connection request based on the two-dimensional code 17, and by comparing it with the trapped information, it can be determined whether the portable terminal 30 is at the place where a trap has occurred.

[0090] As described above, according to the present invention, for an elevator device of a communication device without a camera and camera images, a remote monitoring system capable of performing remote rescue in case of entrapment can be constructed by using the camera function of the portable terminal of the elevator user.
