Description

[Technical Field]

[0001] The present invention relates to an elevator entrapment rescue system and an elevator entrapment rescue method. [Background technology]

[0002] When a large earthquake occurs, elevators often stop operating due to seismometers, resulting in passengers becoming trapped inside. When an elevator becomes trapped, elevator engineers typically head to the scene to perform rescue operations. However, the number of rescue engineers is limited, making it difficult to dispatch an equal number of engineers to all trapped locations. As a result, passengers at the scene who are placed last in the rescue operation are trapped for long periods of time, causing psychological and physical pain. To address this issue, technologies have been disclosed that disclose the status of passengers trapped inside an elevator car to relevant parties, such as the technology described in Patent Document 1.

[0003] Patent document 1 states that "when an elevator malfunction occurs, information about the information center written in the two-dimensional code contained in the image displayed on the hall image display unit is read, and the image sent from the car interior image sending means is transferred according to instructions from the accessed mobile phone." [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-51641 Summary of the Invention [Problem to be solved by the invention]

[0005] As mentioned above, when someone is trapped in an elevator, a technology has been developed that discloses images of the inside of the car to relevant parties such as the building manager or maintenance staff. However, when multiple people are trapped, the technology described in Patent Document 1 does not determine the priority of rescue based on the condition of the elevator or the status of the passengers, which can lead to long waiting times.

[0006] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to prevent long-term confinement in an elevator when it occurs, and to shorten the average confinement time. [Means for solving the problem]

[0007] The elevator confinement rescue system of the present invention is a rescue system for confined persons in an elevator, comprising a remote monitoring device that monitors and remotely controls the operation status of an elevator, and a control device that controls the operation status of elevators within a controlled area. The remote monitoring device detects confinement that has occurred due to an abnormal stop of the elevator and determines whether the confinement meets predetermined rescue conditions. If the control device determines through the remote monitoring device that the confinement meets the predetermined rescue conditions, it requests rescue of the confined persons from relevant parties at the elevator site. The above-described elevator confinement rescue system is one aspect of the present invention, and an elevator confinement rescue method that reflects one aspect of the present invention is also configured in the same manner as the above-described elevator confinement rescue system. [Effects of the Invention]

[0008] According to the present invention having the above configuration, when an elevator becomes confined, it is possible to prevent the elevator from being confined for a long period of time and to shorten the average confinement time. Problems, configurations, and effects other than those described above will become apparent from the following description of the embodiments. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In this specification and drawings, components having substantially the same functions or configurations are designated by the same reference numerals, and redundant description will be omitted.

[0011] <One embodiment> [Configuration example of an elevator confinement rescue system] First, a configuration example of an elevator confinement rescue system according to one embodiment of the present invention will be described. Fig. 1 is a diagram showing a configuration example of an elevator confinement rescue system 1 according to this embodiment. Note that Fig. 1 shows only the components related to the present invention, and illustration and description of other components are omitted.

[0012] 1, the elevator confinement rescue system 1 includes an elevator 10, an elevator control panel 20, a remote monitoring device 30, a communication device 40, a control device 50, and a diagnostic server 60. The elevator confinement rescue system 1 also includes a customer service server 70, an alarm issuing agency 80, a mobile terminal 90a, a customer mobile terminal 90b, and a customer stationary terminal 90c.

[0013] (1) Elevator 10 As shown in Figure 1, elevator 10 has car 11, hoist 12, counterweight 13, and seismometer 14. Car 11 and counterweight 13 are wound around hoistway 12 by a rope and suspended from a hoistway (not shown). Counterweight 13 is a weight used to achieve balance. Seismometer 14 is installed inside car 11, detects shaking caused by an earthquake, and outputs the measured value of the detected shaking to elevator control panel 20.

[0014] (2) Elevator control panel 20 The elevator control panel 20 is an example of a control device that controls the overall operation of the elevator 10. The elevator control panel 20 controls, for example, the ascending and descending speed of the car 11, the landing operation at the landing floor, and the opening and closing of the car doors. As shown in FIG. 1, the elevator control panel 20 has an operation control unit 21, a speed control unit 22, a measurement unit 23, and a communication unit 24. The elevator control panel 20 is placed, for example, in a machine room (not shown) above the elevator shaft.

[0015] The operation control unit 21 performs control related to the operation of the elevator 10. For example, the operation control unit 21 controls the motor that drives the elevator 10, controls the raising and lowering operation of the car 11 to the destination floor, and controls the opening and closing of the doors of the car 11.

[0016] The speed control unit 22 controls the operating speed of the car 11, for example, controls acceleration, deceleration, constant speed operation, and the like.

[0017] The measurement unit 23 measures various data related to the operating state of the elevator 10 and outputs the data to the remote monitoring device 30 via the communication unit 24. The measurement unit 23 measures various operating state data such as the landing floor of the elevator 10, the stopping position, the presence or absence of passengers, the operating speed, and measurement data from the seismometer 14.

[0018] The communication unit 24 transmits and receives various data to and from the remote monitoring device 30. The hardware configuration of the elevator control panel 20 will be described in detail later with reference to FIG.

[0019] (3) Remote monitoring device 30 The remote monitoring device 30 is a computer device connected to the elevator control panel 20, and monitors the operating status of the elevator 10 and performs remote control, etc. As shown in FIG. 1 , the remote monitoring device 30 has a measurement unit 31, an abnormality detection unit 32, an abnormality reporting unit 33, and a communication unit 34.

[0020] The measurement unit 31 analyzes operation information for monitoring the elevator 10 using the operation status data input from the elevator control panel 20. The operation information is various data for monitoring the operating status of the elevator 10, such as the acceleration time of the elevator 10, the congestion time, and the landing position of the elevator 10.

[0021] The abnormality detection unit 32 detects an abnormal state of the elevator 10 based on the operation information analyzed by the measurement unit 31. The abnormal state of the elevator 10 includes all abnormal states other than a normal operating state, such as an abnormal stop of the elevator 10, entrapment caused by an abnormal stop, and a shift in the landing position.

[0022] The abnormality alarm issuing unit 33 generates alarm information indicating the abnormal state of the elevator 10 detected by the abnormality detection unit 32 and transmits it to the control device 50 via the communication unit 34.

[0023] The communication unit 34 transmits and receives various data to and from the elevator control panel 20, and transmits operation information and abnormal state alert information to the control device 50 via the communication device 40. The hardware configuration of the remote monitoring device 30 will be described in detail later with reference to FIG. 2.

[0024] The communication device 40 uses, for example, a NIC (Network Interface Card) or the like, and transmits and receives various data to and from the control device 50 and the diagnostic server 60 via a closed network W1 connected to a terminal of the NIC.

[0025] Although the above description has been given of an example in which there is only one elevator 10 and one elevator control panel 20, the present invention is not limited to this. There may be multiple elevators 10. In this case, an elevator control panel 20 is provided for each of the multiple elevators 10. The multiple elevator control panels 20 are connected to the remote monitoring device 30.

[0026] (4) Control device 50 The control device 50 is a terminal device that is placed in a control center and receives operation information and abnormality alert information from the remote monitoring device 30 that monitors the elevators 10 in the controlled area, and controls the operating status of the elevators 10 in the controlled area. As shown in Figure 1, the control device 50 has an alert receiving unit 51, an alarm detection unit 52, and a communication unit 53.

[0027] The alert receiving unit 51 receives calls from the handset in the car 11 of the elevator 10 to the control device 50 and abnormality alert information from the remote monitoring device 30, and if maintenance work by an engineer is required, notifies the engineer of the work. When notifying the engineer of the work, the alert receiving unit 51 registers information such as the work location and time in the customer service server 70 via the public network W2. The customer service server 70 transmits the work notification registered by the alert receiving unit 51 to the mobile terminal 90a of the engineer P1. Note that the present invention is not limited to this, and the work notification to the engineer may be sent, for example, via email.

[0028] The alarm detection unit 52 determines whether the control area of ​​the device itself is included in the area subject to the issuance of an alarm based on the issuance of an alarm from the alarm issuing organization 80. If the alarm detection unit 52 determines that the control area of ​​the device itself is included in the area subject to the issuance of an alarm, it transmits the issuance of an alarm to the remote monitoring device 30 that monitors the elevators 10 in the control area. The alarm detection unit 52 may also notify the issuance of an alarm via the customer service server 70 to customers P2 who use the elevators 10 in the control area and engineers P1 who can perform maintenance work on the elevators 10. The communication unit 53 transmits and receives various data. The hardware configuration of the control device 50 will be described in detail later with reference to FIG. 2.

[0029] (5) Diagnostic Server 60 The diagnostic server 60 generates various data for customer-oriented services and provides the data to the customer-oriented service server 70. As shown in FIG. 1 , the diagnostic server 60 includes a data processing unit 61, a diagnostic unit 62, a database (DB) unit 63, and a communication unit 64.

[0030] The data processing unit 61 performs various processes to provide various data for customer services based on the various data received from the remote monitoring device 30. The various data for customer services is, in other words, various data on a report to be displayed on a service screen for the customer. Specific examples of the various data on the report include information for customer P2 regarding whether the elevator 10 is available for boarding, information regarding the congestion status, information about the maintenance work location for engineer P1, and abnormality information about the elevator 10.

[0031] The diagnosis unit 62 determines whether or not the elevator 10 is accessible, determines the congestion situation, etc., based on the various data generated by the data processing unit 61.

[0032] The DB unit 63 stores various data transmitted from the remote monitoring device 30. The DB unit 63 may also store various data generated by the data processing unit 61. The communication unit 64 transmits and receives various data. The hardware configuration of the diagnostic server 60 will be described in detail later with reference to FIG. 2.

[0033] (6) Customer service server 70 The customer service server 70 provides various services related to the elevator 10 to customers who use the elevator 10, related parties including the manager, and engineers who can perform maintenance work. As shown in FIG. 1 , the customer service server 70 has a data processing unit 71, a DB unit 72, and a communication unit 73.

[0034] The data processing unit 71 performs processing to generate a report to be displayed on a service screen for customers. The DB unit 72 stores various data necessary for the report generation process in the data processing unit 71, the generated reports, and the like. The communication unit 64 transmits and receives various data. The hardware configuration of the customer service server 70 will be described in detail later with reference to FIG.

[0035] (7) Engineer / Customer Terminal Devices The terminal devices held by the engineer and the customer are, for example, mobile terminals such as smartphones, or personal computers (PCs). FIG. 1 shows, as an example, a mobile terminal 90a held by an engineer P1, and a customer mobile terminal 90b and a customer stationary terminal 90c held by a customer P2. The mobile terminal 90a, the customer mobile terminal 90b, and the customer stationary terminal 90c have the same configuration as shown in the figure. Hereinafter, when the mobile terminal 90a, the customer mobile terminal 90b, and the customer stationary terminal 90c are not distinguished from one another, they will be collectively referred to as "user terminals."

[0036] As shown in FIG. 1, the user terminal includes a display unit 91, an input unit 92, and a communication unit 93. The display unit 91 displays a service screen for customers, a work screen for engineers, etc. Engineers and customers can input predetermined operation details using the input unit 92. The communication unit 93 transmits and receives various data. The hardware configuration of the engineer / customer terminal device will be described in detail in Figure 2 below.

[0037] [Example of hardware configuration of computers that make up each device] Next, we will explain the hardware configuration of the computer X0 that constitutes each device in the elevator trapped-in-elevator rescue system 1. Fig. 2 is a block diagram showing an example of the hardware configuration of the computer X0 that constitutes each device included in the elevator trapped-in-elevator rescue system 1 according to this embodiment. The computer X0 is an example of hardware used as a computer that can operate as the elevator control panel 20, the remote monitoring device 30, the control device 50, the diagnostic server 60, the customer service server 70, and a user terminal. Note that the diagnostic server 60 and the customer service server 70 may be configured on the cloud instead of on the computer X0.

[0038] The computer X0 includes a CPU (Central Processing Unit) X1, a ROM (Read Only Memory) X2, and a RAM (Random Access Memory) X3, all connected to a bus X4. The computer X0 also includes a display device X5, an input device X6, a non-volatile storage X7, and a network interface X8.

[0039] The CPUX1 reads out the program code of the software that realizes each function according to this embodiment from the ROMX2, loads it into the RAMX3, and executes it. Variables, parameters, etc. that arise during the calculation processing of the CPUX1 are temporarily written to the RAMX3, and these variables, parameters, etc. are read out by the CPUX1 as appropriate. However, an MPU (Micro Processing Unit) may be used instead of the CPUX1.

[0040] The display device X5 is, for example, a liquid crystal display monitor, and displays the results of the processing performed by the computer X0, etc. The input device X6 is, for example, a keyboard, a mouse, etc.

[0041] The nonvolatile storage X7 may be, for example, a hard disk drive (HDD), a solid state drive (SSD), a flexible disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, or a nonvolatile memory. The nonvolatile storage X7 stores an operating system (OS), various parameters, and programs for running the computer X0. The ROM X2 and the nonvolatile storage X7 store programs, data, and the like required for the CPU X1 to operate, and are used as examples of computer-readable, non-transitory storage media that store programs executed by the computer X0.

[0042] The network interface X8 may be, for example, a NIC, and various data can be transmitted and received between devices via a LAN (Local Area Network), a dedicated line, or the like connected to a terminal of the NIC.

[0043] [Trapped Person Rescue Procedure Example 1] Next, a first example of a confinement rescue process in the elevator confinement rescue system 1 will be described. In the first example of the confinement rescue process, the remote monitoring device 30 detects a confinement caused by an abnormal stop of the elevator 10 and determines whether the confinement satisfies a predetermined rescue condition. If the remote monitoring device 30 determines that the confinement satisfies the predetermined rescue condition, the control device 50 requests rescue from relevant parties at the elevator site. Here, the predetermined rescue condition is that the stopping position of the elevator 10 is within a predetermined distance from the floor of the nearest floor and no warnings that would affect rescue from the confinement are issued. The relevant parties include customers and managers at the elevator site. The procedure of the first example of the confinement rescue process will be described with reference to FIG. 3. FIG. 3 is a flowchart showing the procedure of the first example of the confinement rescue process in the elevator confinement rescue system 1 according to this embodiment. The process described below may be executed every time the seismometer 14 installed in the elevator 10 detects shaking caused by an earthquake, or may be executed at predetermined intervals.

[0044] First, the elevator control panel 20 acquires the measured value of the vibration from the seismometer 14 (step S100).

[0045] Next, the elevator control panel 20 determines whether or not the acquired measurement value of the vibration is equal to or greater than a threshold value corresponding to the suspension of operation (step S101).

[0046] In the process of step S101, when the elevator control panel 20 determines that the acquired measurement value of the shaking is equal to or greater than the threshold value (YES determination in step S101), it stops the elevator 10 (step S103).

[0047] On the other hand, in the processing of step S101, if the elevator control panel 20 determines that the acquired shaking measurement value is less than the threshold value (NO judgment in step S101), it determines whether the car 11 has landed at the nearest floor through controlled operation (step S102).

[0048] In the process of step S102, if the elevator control panel 20 determines that the car 11 has landed at the nearest floor by controlled operation (YES determination in step S102), the process of step S121 described below is performed.

[0049] On the other hand, in the process of step S102, if it is determined that the car 11 has not arrived at the nearest floor (NO determination in step S102), the elevator control panel 20 performs the process of step S104 described below.

[0050] After the process of step S103, or if the determination in step S102 is NO, the abnormality detection unit 32 of the remote monitoring device 30 determines whether or not there is a passenger in the elevator car 11 (step S104). In this process, the abnormality detection unit 32 of the remote monitoring device 30 determines whether or not there is a passenger based on, for example, an image of the interior of the elevator car captured by an imaging device installed in the elevator car 11.

[0051] In the process of step S104, if the abnormality detection unit 32 of the remote monitoring device 30 determines that there is no passenger in the car 11 (NO determination in step S104), the process of step S121 described below is performed.

[0052] On the other hand, in the process of step S104, if the abnormality detection unit 32 of the remote monitoring device 30 determines that there is a passenger in the car 11 (YES determination in step S104), it confirms that a person is locked in (step S105).

[0053] Next, the operation control unit 21 of the elevator control panel 20 determines whether the measured value of the shaking has become less than the threshold value (step S106). In this process, the elevator control panel 20 acquires the measured value of the shaking from the seismometer 14 at predetermined time intervals, for example, and determines whether the measured value of the shaking has become less than the threshold value.

[0054] In the process of step S106, if the operation control unit 21 of the elevator control panel 20 determines that the measured value of the shaking is equal to or greater than the threshold value (NO determination in step S106), it repeatedly executes the process of step S106.

[0055] On the other hand, if, in the process of step S106, the operation control unit 21 of the elevator control panel 20 determines that the measured value of the shaking has fallen below the threshold value (YES determination in step S106), the abnormality detection unit 32 of the remote monitoring device 30 performs the process of step S107. In the process of step S107, the abnormality detection unit 32 determines whether the stopping position of the car 11 is within a predetermined distance from the floor surface of any floor. Here, the predetermined distance is set, for example, to a distance at which the manager of the building where the elevator 10 is located or other customers in the building can rescue trapped passengers. Furthermore, this predetermined distance is registered in advance in the remote monitoring device 30.

[0056] In the process of step S107, if the abnormality detection unit 32 determines that the stopping position of the car 11 exceeds a predetermined distance from the floor surface of any floor (NO determination in step S107), the process of step S121 described later is performed.

[0057] On the other hand, in the processing of step S107, if the abnormality detection unit 32 determines that the position of the car 11 is within a predetermined distance from the floor surface of any floor (YES determination in step S107), it determines whether an Earthquake Early Warning has been issued (step S108). In this processing, if the abnormality detection unit 32 receives an Earthquake Early Warning from the control device 50 via the communication device 40, the determination in step S108 is NO. On the other hand, if the abnormality detection unit 32 has not received an Earthquake Early Warning from the control device 50 via the communication device 40, the determination in step S108 is YES.

[0058] In the process of step S107, if the abnormality detection unit 32 determines that an emergency earthquake warning is being issued (NO determination in step S108), the process of step S121 described below is performed.

[0059] On the other hand, in the process of step S107, if the abnormality detection unit 32 determines that an Earthquake Early Warning has not been issued (YES determination in step S108), it determines whether any other warnings have been issued (step S109). In this process, if the abnormality detection unit 32 receives, from the control device 50 via the communication device 40, another warning that will affect the operation of the elevator, such as a warning about a tsunami or a landslide, the determination in step S109 is NO. On the other hand, if the abnormality detection unit 32 has not received, from the control device 50 via the communication device 40, another warning that will affect the operation of the elevator, the determination in step S109 is YES. Note that the above-mentioned Earthquake Early Warning and other warnings such as a tsunami or a landslide are examples of warnings that will affect the rescue of trapped persons.

[0060] In the process of step S109, if the abnormality detection unit 32 determines that another alarm that will affect the operation of the elevator is being issued (NO determination in step S109), the process of step S121 described below is performed.

[0061] On the other hand, if, in the process of step S109, the abnormality detection unit 32 determines that no other alarm affecting the operation of the elevator is currently being issued (YES determination in step S109), the process of step S120 is performed. In the process of step S120, the abnormality detection unit 32 transmits a trapped-in rescue request to the control device 50 via the communication device 40. Furthermore, the control device 50 requests rescue from the customer at the site of the elevator 10 and the manager of the building where the elevator 10 is located via the customer service server 70. Note that the trapped-in rescue request may be transmitted to the customer at the elevator 10 and the manager of the building where the elevator 10 is located, for example, by email or the like.

[0062] After the processing of step S120, if the determination is NO in step S102, NO in step S104, NO in step S107, NO in step S108, or NO in step S109, the remote monitoring device 30 waits until the engineer P1 restores operation of the elevator 10 (step S121). In this process, the seismometer 14 is also restored by the engineer P1. After the processing of step S121, the trapped-in rescue process ends.

[0063] By the above-mentioned process, when an elevator becomes trapped, if other passengers using the elevator or the building manager can rescue the trapped passengers, the passengers can be rescued by the passengers or the building manager on-site without waiting for an engineer. Therefore, according to the present invention, it is possible to prevent long-term trapped passengers and, when multiple trapped passengers occur, to shorten the average trapped time.

[0064] [Trapped Person Rescue Procedure Example 2] Next, a second example of a confinement rescue process in the elevator confinement rescue system 1 will be described. The second example of a confinement rescue process takes into account the length of time a passenger is trapped. In the second example of a confinement rescue process, the predetermined rescue conditions for confinement include the passage of a certain amount of time since the occurrence of the confinement, or the expected time until rescue from the confinement being equal to or longer than a predetermined waiting time. The procedure for the second example of a confinement rescue process will be described with reference to FIG. 4. FIG. 4 is a flowchart showing the procedure for the second example of a confinement rescue process in the elevator confinement rescue system 1 according to this embodiment. The process described below may be executed every time the seismometer 14 installed in the elevator 10 detects shaking caused by an earthquake, or may be executed at predetermined intervals, as in the first example of a confinement rescue process described in FIG. 3. Note that steps S100 to S109 shown in FIG. 4 are the same as those shown in FIG. 3, and therefore will not be described again.

[0065] In the second example of the trapped-in rescue process, if the determination in step S109 is YES, the abnormality detection unit 32 of the remote monitoring device 30 determines whether a certain period of time has passed since the trapped-in occurred (step S201). Here, the certain period of time is set to an appropriate length in advance, taking into consideration the stress that passengers may experience due to the length of time they are trapped.

[0066] In the process of step S201, if the abnormality detection unit 32 determines that a certain time has passed since the entrapment occurred (YES determination in step S201), the process of step S120 is performed. That is, taking into consideration the stress of passengers, rescue requests are given priority for those who are entrapped after a certain time has passed. Note that the process of step S120 is the same as the process of this step shown in FIG. 3, so a duplicated description will be omitted.

[0067] On the other hand, in the process of step S201, if it is determined that a certain time has not elapsed since the entrapment occurred (NO determination in step S201), the abnormality detection unit 32 determines whether the expected time until rescue is equal to or longer than a predetermined waiting time (step S202). Here, the expected time until rescue is determined, for example, by the control device 50 predicting the time it will take for an engineer to arrive at the scene based on the current location of the engineer heading to the rescue and traffic conditions, and transmitting this to the remote monitoring device 30 via a customer service. The predetermined waiting time is set to an appropriate time in advance.

[0068] In the process of step S202, if the abnormality detection unit 32 determines that the estimated time until rescue is less than the predetermined waiting time (NO determination in step S202), the process returns to the process of step S201, and the processes of steps S201 and S202 are repeatedly executed.

[0069] On the other hand, in the process of step S202, if the abnormality detection unit 32 determines that the expected time until rescue is equal to or longer than the predetermined waiting time (YES determination in step S202), or if the determination in step S201 is YES, the process of step S120 is performed. That is, if the predetermined waiting time is exceeded until an engineer arrives at the site of the entrapment, a rescue request is made with priority for the entrapment.

[0070] After the process of step S120, the abnormality detection unit 32 determines whether the trapped passengers have been rescued (step S203). In this process, the abnormality detection unit 32 makes the determination based on the video of the inside of the car 11, for example.

[0071] In the process of step S203, if the abnormality detection unit 32 determines that the trapped passengers have not been rescued (NO determination in step S203), the process returns to the process of step S201, and the processes of steps S201 to S203 are repeatedly executed.

[0072] On the other hand, in the process of step S203, if the abnormality detection unit 32 determines that the trapped passengers have been rescued (YES determination in step S203), the process of step S121 is performed. Note that the process of step S121 is the same as the process of this step shown in Fig. 3, so a duplicated description will be omitted.

[0073] In Example 2 of the confinement rescue process, when multiple elevators are confined within a controlled area, the system takes into consideration the length of time passengers have been trapped, and prioritizes rescue requests for those trapped for which a certain amount of time has passed since the trapping occurred, or for which the estimated time until rescue is equal to or longer than a predetermined waiting time. Therefore, this invention can prevent passengers from being trapped for long periods of time, thereby reducing passenger stress.

[0074] [Trapped Person Rescue Procedure Example 3] Next, a third example of a confinement rescue process in the elevator confinement rescue system 1 will be described. The third example of the confinement rescue process takes into account the state of the elevator's equipment. In the third example of the confinement rescue process, the predetermined rescue conditions for confinement include the measured value of the shaking detected by a seismometer installed in the elevator being equal to or less than a certain value, and the elevator being unable to move. The procedure for the third example of the confinement rescue process will be described with reference to FIG. 5. FIG. 5 is a flowchart showing the procedure for the third example of the confinement rescue process in the elevator confinement rescue system 1 according to this embodiment. The following process, similar to the first example of the confinement rescue process described in FIG. 3, may be executed every time the seismometer 14 installed in the elevator 10 detects shaking due to an earthquake, or may be executed at predetermined intervals. Note that steps S100 to S105 and S107 to S109 shown in FIG. 5 are the same as those shown in FIG. 3, and therefore will not be described again. In the confinement rescue process example 3, the process of step S106 shown in FIG. 3 is not performed, and after the process of step S105, the process of step S107 is performed.

[0075] In the confinement rescue processing example 3, if the determination in step S109 is YES, the abnormality detection unit 32 of the remote monitoring device 30 determines whether the measured value of the shaking detected by the seismometer 14 is equal to or less than a certain value (step S301). Here, the certain value is a value greater than the threshold value in step S101. The shaking equal to or less than the certain value is shaking that can be tolerated even if the elevator 10 is moved slowly.

[0076] In step S301, if the abnormality detection unit 32 determines that the measurement value of the shaking detected by the seismometer 14 exceeds a certain value (NO determination in step S301), the process of step S121 is performed. Note that the process of step S121 is the same as the process of this step shown in Fig. 3, so a duplicated description will be omitted.

[0077] On the other hand, in step S301, if the abnormality detection unit 32 determines that the measured value of the shaking detected by the seismometer 14 is equal to or less than a certain value (YES in step S301), it determines whether or not the rope has been caught on equipment inside the tower (step S302). In this process, the remote monitoring device 30 issues a command to the elevator control panel 20 to start the motor of the elevator 10 and gradually move the car 11. The operation control unit 21 of the elevator control panel 20 operates the motor according to the command, detects the torque when the motor is rotating, and outputs the torque to the remote monitoring device 30. If the detected torque when the motor is rotating is equal to or greater than a predetermined threshold, the abnormality detection unit 32 of the remote monitoring device 30 determines that the rope suspending the car 11 is caught on equipment inside the hoistway (inside the tower) and is unable to move. In this case, a situation occurs in which rescue is required for the trapped person. On the other hand, if the detected torque when the motor is rotating is less than the predetermined threshold, the abnormality detection unit 32 of the remote monitoring device 30 determines that the car 11 is in a movable state. In this case, the remote monitoring device 30 outputs an instruction to move the car 11 little by little and land at the nearest floor to the operation control unit 21 of the elevator control panel 20. Once the car 11 has landed, the trapped passengers can get out of the car without the need for rescue.

[0078] In the processing of step S302, if the abnormality detection unit 32 determines that it has not detected that the rope has been caught on equipment inside the tower (NO judgment in step S302), the trapped passengers can get out of the car without needing to be rescued, so the processing of step S121 is performed.

[0079] On the other hand, if the abnormality detection unit 32 determines in the processing of step S302 that the rope has been caught on equipment inside the tower (YES determination in step S302), the situation requires rescue from the trapped person, so the processing of step S120 is performed.

[0080] In the example 3 of the trapped-in rescue process, the elevator is unable to move because the rope is caught on equipment inside the tower, but the present invention is not limited to this. The elevator is unable to move also includes any state where it is dangerous for anyone other than an elevator expert (e.g., an engineer) to operate it.

[0081] In the third example of trapped passenger rescue processing, if the elevator can be moved slowly, the car is landed at the nearest floor and the trapped passengers are released. Furthermore, if the elevator is unable to move, the trapped passengers can be rescued by requesting rescue from other customers using the elevator or the building manager. Therefore, according to the present invention, it is possible to prevent long-term trapped passengers and shorten the average trapped time.

[0082] [effect] As described above, when an elevator is trapped in a passenger's car, the elevator confinement rescue system 1 according to this embodiment can rescue trapped passengers by requesting rescue from other passengers using the elevator or the building manager, without waiting for an engineer, if the trapped passenger can be rescued by other passengers using the elevator or the building manager. Furthermore, the elevator confinement rescue system 1 prioritizes rescue requests for trapped passengers who have been trapped for a certain period of time or more since the trapping occurred, or for whom the estimated time until rescue is longer than a predetermined waiting time. Furthermore, if the elevator can move slowly, the elevator confinement rescue system 1 lands the car at the nearest floor and releases trapped passengers. Furthermore, if the elevator is unable to move, the system requests rescue from other passengers using the elevator or the building manager. Therefore, the elevator confinement rescue system 1 according to this embodiment can prevent long-term confinement and, when multiple confinement events occur, shorten the average confinement time.

[0083] The present invention is not limited to the above-described embodiment, and it goes without saying that various other applications and modifications are possible without departing from the gist of the present invention as set forth in the claims. For example, the above-described embodiment has described in detail and specifically the configuration of the elevator entrapment rescue system in order to clearly explain the present invention, and is not necessarily limited to having all of the described configurations. Furthermore, it is possible to replace part of the configuration of the embodiment described here with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. Furthermore, it is also possible to add, delete, or replace part of the configuration of an embodiment with other configurations. In addition, the control lines and information lines shown are those that are considered necessary for the explanation, and do not necessarily show all the control lines and information lines in the product. In reality, it can be assumed that almost all components are interconnected. [Explanation of symbols]
