DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] In order to explain the present disclosure in more detail, embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0010] Embodiment 1 In the first embodiment, a basic configuration of the elevator shaft monitoring device will be described.

[0011] An example of the configuration of the elevator shaft monitoring device according to the first embodiment will be described. FIG. 1 is a diagram illustrating an example of a configuration of an elevator shaft monitoring device 100 according to the first embodiment of the present disclosure. The elevator shaft monitoring device 100 monitors an elevator shaft, which is a space in an elevator where an elevator car ascends and descends. The elevator shaft monitoring device 100 outputs the state of the elevator shaft structure. The elevator shaft structure includes structures present in the space in which the elevator car ascends and descends, such as the interior walls of the elevator shaft, steel frames, beams, ropes (wires), counterweights, guide rails, buffers, fallen objects, etc. The state of the elevator shaft structure may further include objects such as fallen objects in addition to the state of structures that are normally present in the elevator shaft. The elevator shaft monitoring device 100 obtains the state of the elevator shaft structure using images captured by the imaging device and sensor signals measured by the sensor device. The elevator shaft monitoring device 100 shown in FIG. 1 includes an image acquisition unit 110, a sensor signal acquisition unit 120, and an elevator shaft state output unit .

[0012] The captured image acquisition unit 110 acquires an image captured inside the elevator shaft. The captured image acquisition unit 110 acquires a first image from a first imaging device 210 that captures an image of the area above the elevator car, and acquires a second image from a second imaging device 230 that captures an image of the area below the elevator car. The captured image acquisition unit 110 acquires, for each position of the elevator car, a first image captured above the elevator shaft from the position of the elevator car, and a second image captured below the elevator shaft from the position of the elevator car.

[0013] The sensor signal acquisition unit 120 acquires a sensor signal that is a result of measuring the inside of the hoistway. The sensor signal acquiring unit 120 acquires a first sensor signal from a first sensor device 220 that measures above the elevator car, and acquires a second sensor signal from a second sensor device 240 that measures below the elevator car. The sensor signal includes information that allows the measurement results to be expressed in the form of points and point clouds, for example, based on the position of the sensor device. The sensor signal acquisition unit 120 acquires, for each position of the elevator car, a first sensor signal which is the result of measuring above the elevator shaft from the position of the elevator car, and a second sensor signal which is the result of measuring below the elevator shaft from the position of the elevator car.

[0014] The hoistway status output unit 130 outputs the status of the hoistway based on the image and the sensor signal. The hoistway status output unit 130 outputs hoistway status information indicating the status of the hoistway, using the first image and the first sensor signal, and the second image and the second sensor signal. The hoistway status information is generated by combining images and sensor signals. The elevator shaft state information is information that can be represented, for example, by superimposing an image and points (point cloud) represented by a sensor signal for each position of the elevator car. With this information, even in areas where the state of the structure is unclear from the image alone, the state of the structure can be made clear by using a point cloud based on the sensor signals.

[0015] In addition to the above configuration, the elevator shaft monitoring device 100 may be configured to include a control unit (not shown) and a storage unit (not shown). A control unit (not shown) controls the entire elevator shaft monitoring device 100. The control unit (not shown) starts up or shuts down the elevator shaft monitoring device 100 in accordance with, for example, an external command. The control unit (not shown) also works with the elevator car control device to put the elevator shaft monitoring device 100 into a sleep state depending on the state (rest state) of the elevator car. A storage unit (not shown) stores each piece of data used in the elevator shaft monitoring device 100. The storage unit (not shown) stores, for example, the output (output data) from each component in the elevator shaft monitoring device 100, and outputs data requested by each component to the component that has made the request. This also applies to the other embodiments.

[0016] An example of the configuration of an elevator monitoring system 1A including an elevator shaft monitoring device 100A in the case where the elevator shaft monitoring device 100 according to the first embodiment is applied to an elevator monitoring system will be described. FIG. 2 is a diagram showing an example of a configuration of an elevator monitoring system 1A including an elevator shaft monitoring device 100A according to the first embodiment of the present disclosure. FIG. 3 shows an image of an example implementation of imaging devices (first imaging device 210, second imaging device 230) and sensor devices (first sensor device 220, second sensor device 240) in an elevator monitoring system 1A according to embodiment 1 of the present disclosure. The elevator monitoring system 1A is a system for monitoring an elevator, and in particular has a function for monitoring the elevator shaft 1001. The elevator monitoring system 1A shown in Figure 2 is configured to include an elevator shaft monitoring device 100A, a first imaging device 210, a first sensor device 220, a second imaging device 230, a second sensor device 240, an elevator car position acquisition device 250, and an information presentation device 300.

[0017] The elevator car position acquisition device 250 acquires information relating to the position of the elevator car 1002 in the elevator shaft 1001 . The elevator car position acquisition device 250 calculates the position of the elevator car 1002 in the elevator shaft 1001, for example, by using a reference position in the elevator shaft 1001 and an elevation speed, which is a time-series speed at which the elevator car 1002 ascends and descends. The reference position is a position of the elevator shaft that is set and stored in advance, and can be set to a position where the elevator car 1002 stops on the first floor of a building, for example. Alternatively, the elevator car position acquisition device 250 may be configured to acquire only the elevator speed, for example. In this case, the elevator shaft monitoring device 100A is configured to store a reference position in advance and calculate a position using the reference position and the elevator speed. Alternatively, the elevator car position acquisition device 250 may directly acquire the position of the elevator car 1002 in the elevator shaft 1001 using, for example, a sensor or the like. The elevator car position acquisition device 250 outputs information relating to the acquired position of the elevator car 1002 . The elevator car position acquisition device 250 shown in FIG. 2 outputs information relating to the position of the elevator car 1002 to each of the first imaging device 210, the first sensor device 220, the second imaging device 230, and the second sensor device 240.

[0018] The first imaging device 210 is installed on the upper outer periphery of a car 1002 that moves up and down a hoistway 1001 of an elevator. It is assumed that the first imaging device 210 is permanently installed on the car 1002. The first imaging device 210 is, for example, a visible light camera capable of imaging using visible light. The first imaging device 210 captures an image of the elevator shaft 1001 above the elevator car 1002, and outputs the captured image (first image). The first imaging device 210 outputs the first image together with information related to the position of the elevator car 1002, which is the imaging position.

[0019] The first sensor device 220 is installed on the upper outer periphery of a car 1002 for ascending and descending in a hoistway 1001 of an elevator. It is assumed that the first sensor device 220 is permanently installed on the car 1002 for ascending and descending. The first sensor device 220 is, for example, a laser device that performs measurements by transmitting and receiving a laser. The first sensor device 220 measures the elevator shaft 1001 above the elevator car 1002, and outputs a sensor signal (first sensor signal) that is the measurement result. The first sensor device 220 outputs the first sensor signal together with information related to the position of the elevator car 1002, which is the measurement position.

[0020] Specifically, the first imaging device 210 and the first sensor device 220 are configured in the form of an integrated unit, for example, as shown in Fig. 3, and are fixed and installed on the outer circumferential upper surface part of the elevator car 1002. The outer circumferential upper surface part of the elevator car 1002 is the part that faces the side in which the elevator car 1002 ascends when the elevator car is attached in the elevator shaft. The first imaging device 210 and the first sensor device 220 output the first image, the first sensor signal, and information related to the position of the lifting car 1002. As a result, the first image, the first sensor signal, and the positions at which they were acquired (imaging position and measurement position) are output in an associated form.

[0021] The second imaging device 230 is installed on the lower outer periphery of a lift car 1002 that moves up and down a hoistway 1001 of an elevator. The second imaging device 230 is assumed to be permanently installed on the lift car 1002. Like the first imaging device 210, the second imaging device 230 is, for example, a visible light camera capable of imaging with visible light. The second imaging device 230 captures an image of the elevator shaft 1001 below the elevator car 1002, and outputs the captured image (second image).

[0022] The second sensor device 240 is installed on the lower outer periphery of a lift car 1002 that moves up and down a hoistway 1001 of an elevator. The second sensor device 240 is assumed to be permanently installed on the lift car 1002. Similar to the first sensor device 220, the second sensor device 240 is, for example, a laser device that performs measurements by transmitting and receiving a laser. The second sensor device 240 measures the elevator shaft 1001 below the elevator car 1002, and outputs a sensor signal (second sensor signal) that is the measurement result.

[0023] Specifically, the second imaging device 230 and the second sensor device 240 are configured in the form of an integrated unit, for example, as shown in Fig. 3, and are fixed and installed on the outer periphery underside of the elevator car 1002. The outer periphery underside of the elevator car 1002 is the part that faces the side from which the elevator car 1002 descends when the elevator car 1002 is attached inside the elevator shaft. The second imaging device 230 and the second sensor device 240 output the second image, the second sensor signal, and information related to the position of the lifting car 1002. As a result, the second image, the second sensor signal, and the positions at which they were acquired (imaging position and measurement position) are output in an associated form.

[0024] Like the elevator shaft monitoring device 100 already described, the elevator shaft monitoring device 100A is configured to be able to monitor the elevator shaft, which is the space in an elevator where an elevator car ascends and descends. The elevator shaft monitoring device 100A shown in FIG. 2 includes a captured image acquiring section 110, a sensor signal acquiring section 120, and an elevator shaft state output section 130, similar to the elevator shaft monitoring device 100 already described.

[0025] The captured image acquisition unit 110 of the elevator shaft monitoring device 100A is configured to acquire images captured inside the elevator shaft, similar to the captured image acquisition unit 110 already described. The captured image acquisition section 110 shown in FIG. 2 acquires a first image output from a first imaging device 210, and acquires a second image output from a second imaging device 230.

[0026] The sensor signal acquirer 120 of the elevator shaft monitoring device 100A is configured to acquire a sensor signal that is a result of measuring the inside of the elevator shaft, similar to the sensor signal acquirer 120 already described. The sensor signal acquiring unit 120 shown in FIG. 2 acquires a first sensor signal output from a first sensor device 220, and acquires a second sensor signal output from a second sensor device 240.

[0027] The shaft state output unit 130 of the shaft monitoring device 100A is configured to output the state of the shaft based on the image and the sensor signal, similar to the shaft state output unit 130 already described. The elevator shaft state output unit 130 shown in FIG. 2 outputs elevator shaft state information indicating the state of the elevator shaft to the information presentation device 300.

[0028] With this configuration, the elevator shaft monitoring device 100A outputs elevator shaft state information to the information presentation device 300.

[0029] The information presentation device 300 is a device that presents information. Specifically, the information presentation device 300 presents information by displaying an image. The information presentation device 300 also presents information by outputting sound. The information presentation device 300 is, for example, a display device such as a display device, a terminal device, a mobile terminal, a tablet terminal, or the like. The information presentation device 300 presents the state of the elevator shaft using the elevator shaft state information output by the elevator shaft monitoring device 100A.

[0030] A processing example in the elevator monitoring system 1A and a processing example in the elevator shaft monitoring device 100A will be described. FIG. 4 is a flowchart showing an example of an imaging process in the elevator monitoring system 1A according to the first embodiment of the present disclosure. When an imaging device (first imaging device 210, second imaging device 230) in the elevator monitoring system 1A receives an instruction from a control unit (not shown) to monitor the elevator shaft, the imaging device receives a control signal from the control unit (not shown) and starts the processing shown in Figure 4.

[0031] The imaging devices (first imaging device 210, second imaging device 230) first execute imaging processing (step ST111). The first imaging device 210 captures an image of the elevator shaft above the elevator car. The second imaging device 230 captures an image of the elevator shaft below the elevator car.

[0032] Next, the imaging devices (the first imaging device 210 and the second imaging device 230) execute a lifting car position acquisition process (step ST112). In the elevator car position acquisition process, the first imaging device 210 acquires information related to the position of the elevator car output by the elevator car position acquisition device 250. The second imaging device 230 acquires information related to the position of the elevator car output by the elevator car position acquisition device 250.

[0033] Next, the imaging devices (first imaging device 210, second imaging device 230) execute a captured image output process (step ST113). In the captured image output process, the first imaging device 210 outputs a first image of the hoistway above the car together with information related to the car's position to the elevator shaft monitoring device 100A. The second imaging device 230 outputs a second image of the hoistway below the car together with information related to the car's position to the elevator shaft monitoring device 100A.

[0034] Next, the imaging devices (first imaging device 210, second imaging device 230) execute an end determination process (step ST114). In the end determination process, if the first imaging device 210 and the second imaging device 230 have not received an imaging end command from a control unit not shown, they each determine not to end the process, and if they have received an imaging end command, they each determine to end the process. If the first imaging device 210 and the second imaging device 230 do not end the process, they each proceed to the process of step ST111 and repeatedly execute the processes from step ST111 onwards.

[0035] When it is determined in the end determination process that the processing should be ended, the imaging devices (the first imaging device 210 and the second imaging device 230) end the processing shown in FIG.

[0036] FIG. 5 is a flowchart showing an example of a measurement process in the elevator monitoring system 1A according to the first embodiment of the present disclosure. When a control unit (not shown) receives an instruction to monitor the elevator shaft, the sensor devices (first sensor device 220, second sensor device 240) in the elevator monitoring system 1A receive a control signal from the control unit (not shown) and start the processing shown in Figure 5.

[0037] The sensor devices (first sensor device 220, second sensor device 240) first execute a measurement process (step ST121). The first sensor device 220 measures the area above the elevator car. The second sensor device 240 measures the area below the elevator car.

[0038] Next, the sensor devices (the first sensor device 220 and the second sensor device 240) execute a lifting car position acquisition process (step ST122). In the elevator car position acquisition process, the first sensor device 220 acquires information related to the position of the elevator car output by the elevator car position acquisition device 250. The second sensor device 240 acquires information related to the position of the elevator car output by the elevator car position acquisition device 250.

[0039] Next, the sensor devices (first sensor device 220 and second sensor device 240) execute a sensor signal output process (step ST123). In the sensor signal output process, the first sensor device 220 outputs a first sensor signal, which is a result of measuring the hoistway above the car, together with information related to the car's position, to the shaft monitoring device 100A. The second imaging device 230 outputs a second sensor signal, which is a result of measuring the hoistway below the car, together with information related to the car's position, to the shaft monitoring device 100A.

[0040] Next, the sensor devices (the first sensor device 220 and the second sensor device 240) execute an end determination process (step ST124). In the termination determination process, if the first imaging device 210 and the second imaging device 230 have not received a measurement termination command from a control unit not shown, they each determine not to terminate the process, and if they have received a measurement termination command, they each determine to terminate the process. When the first imaging device 210 and the second imaging device 230 do not end the process ("NO" in step ST124), they proceed to the process of step ST121 and repeatedly execute the processes from step ST121 onwards.

[0041] Next, when it is determined in the end determination process that the process is to be ended ("YES" in step ST124), the sensor device (the first sensor device 220 and the second sensor device 240) ends the process shown in FIG.

[0042] In the explanation, the processing of the imaging device and the processing of the sensor device are explained separately, but if the imaging device and the sensor device are in the form of an integrated unit, the image and the sensor signal may be output together with information regarding the position of the lifting car.

[0043] FIG. 6 is a flowchart showing an example of the processing of the elevator shaft monitoring device 100 and the elevator shaft monitoring device 100A according to the first embodiment of the present disclosure. The process shown in FIG. 6 corresponds to a shaft monitoring method in which shaft monitoring device 100 is used to monitor a shaft, which is a space in an elevator where a car ascends and descends. When the shaft monitoring devices 100, 100A receive a command to start shaft monitoring processing from a control (not shown), for example, the shaft monitoring devices 100, 100A start the processing shown in FIG.

[0044] The elevator shaft monitoring device 100, 100A first executes a captured image acquisition process (step ST1110). In the captured image acquisition process, the captured image acquisition unit 110 of the elevator shaft monitoring device 100 acquires a first image from the first imaging device 210 that captures an image above the elevator car, and acquires a second image from the second imaging device 230 that captures an image below the elevator car. The captured image acquisition unit 110 acquires the first image including information related to the position of the elevator car, and the second image including information related to the position of the elevator car. The captured image acquisition unit 110 outputs the acquired first image and second image to the elevator shaft state output unit 130.

[0045] Next, the shaft monitoring device 100, 100A executes a sensor signal acquisition process (step ST1120). In the sensor signal acquisition process, the sensor signal acquisition unit 120 of the elevator shaft monitoring device 100 acquires a first sensor signal from a first sensor device 220 that measures above the elevator car, and acquires a second sensor signal from a second sensor device 240 that measures below the elevator car. The sensor signal acquisition unit 120 acquires a first sensor signal including information related to the position of the elevator car, and a second sensor signal including information related to the position of the elevator car. The sensor signal acquirer 120 outputs the acquired first sensor signal and second sensor signal to the elevator shaft state output unit 130.

[0046] Next, the shaft monitoring devices 100, 100A execute a shaft state output process (step ST1130). In the shaft status output process, the shaft status output unit 130 of the shaft monitoring device 100 outputs shaft status information indicating the status of the shaft using a first image and a first sensor signal, and a second image and a second sensor signal. The elevator shaft state output unit 130 outputs elevator shaft state information indicating the state of the elevator shaft to the information presentation device 300.

[0047] Next, the elevator shaft monitoring device 100, 100A ends the process shown in FIG. Alternatively, the elevator shaft monitoring device 100, 100A may proceed to the process of step ST1110, and repeatedly execute the process from step ST1110 until a command to end the process is received.

[0048] The elevator shaft monitoring device having the above configuration can improve the accuracy of information relating to the state inside the elevator shaft in an elevator compared to the prior art. For example, the state of the elevator cannot be obtained with centimeter-level accuracy using only an imaging device such as a camera. Also, to monitor the elevator using only an imaging device such as a camera, sufficient brightness is required, but it is difficult to illuminate the elevator so that the exact state of the elevator is included in the image, making it difficult to obtain highly accurate information. In contrast, the elevator shaft monitoring device configured as described above can obtain highly accurate information and quickly grasp the condition, especially compared to grasping the condition solely using an imaging device such as a camera.

[0049] Furthermore, the elevator shaft monitoring device having the above configuration can enable real-time monitoring, measurement data collection, and measurement data analysis using information with higher accuracy than conventional techniques.

[0053] Embodiment 2 In the second embodiment, an embodiment will be described in which the elevator operates when it is in an abnormal state that is not a normal operation state. In the description of the second embodiment, the same contents as those already described in the first embodiment may be omitted as appropriate.

[0054] An example of the configuration of an elevator monitoring system 1B including an elevator shaft monitoring device 100B in the case where the elevator shaft monitoring device according to the second embodiment is applied to an elevator monitoring system will be described. FIG. 7 is a diagram showing an example of a configuration of an elevator monitoring system 1B including an elevator shaft monitoring device 100B according to the second embodiment of the present disclosure. The elevator monitoring system 1B differs from the elevator monitoring system 1A already described in that, in addition to the above, when a non-normal state notification is received, the elevator monitoring system 1B presents the state of the elevator shaft. The elevator monitoring system 1B shown in Figure 7 is configured to include an elevator shaft monitoring device 100B, a first imaging device 210, a first sensor device 220, a second imaging device 230, a second sensor device 240, an elevator car position acquisition device 250, and an information presentation device 300.

[0055] The first imaging device 210, the first sensor device 220, the second imaging device 230, the second sensor device 240, the elevator car position acquisition device 250, and the information presentation device 300 are each configured to have functions similar to those of the first imaging device 210, the first sensor device 220, the second imaging device 230, the second sensor device 240, the elevator car position acquisition device 250, and the information presentation device 300 already described.

[0056] The elevator shaft monitoring device 100B differs from the elevator shaft monitoring device 100A already described in that it outputs the state of the elevator shaft when a non-normal state notification is received. The elevator shaft monitoring device 100B shown in FIG. 7 includes a captured image acquiring unit 110B, a sensor signal acquiring unit 120B, an elevator shaft state output unit 130B, and a non-normal operation receiving unit 140B.

[0057] The non-normal operation receiving unit 140B receives information that the elevator is not in a normal operation state. The non-normal operation receiving unit 140B receives a non-normal state notification indicating that the elevator is in a non-normal state that is not a normal operating state. The non-normal state includes an emergency shutdown state, a trial run state, a maintenance and inspection state, and an update and repair confirmation state (an update equipment confirmation state, an repair equipment confirmation state). The emergency stop state is a state in which the elevator stops normal operation due to the effects of a disaster such as an earthquake. The emergency stop state is intended to be a state in which, for example, when the shaking caused by an earthquake falls below a predetermined level, workers or the like conduct a pre-check before working in the elevator shaft to confirm whether normal operation is possible. The test operation state is a state in which the elevator is stopped from normal operation and a test operation is performed by an operator or the like. The maintenance inspection state is a state in which the elevator is undergoing maintenance and normal operation is stopped. The maintenance inspection state is assumed to be a state in which, for example, a worker or the like performs a pre-inspection before working in the elevator shaft. The update / repair confirmation state (update equipment confirmation state) is a state in which the elevator equipment is being updated and the elevator is not in normal operation. The update / repair confirmation state is assumed to be a state in which, for example, a worker or the like performs a pre-check before working in the elevator shaft to check the updated equipment and the elevator shaft. The update / repair confirmation state (repair equipment confirmation state) is a state in which the elevator is being repaired and normal operation of the elevator is stopped. The update / repair confirmation state is assumed to be a state in which, for example, a worker or the like performs a pre-check before working in the elevator shaft to check the repaired equipment and the elevator shaft. When the non-normal operation receiving unit 140B receives the non-normal state notification, it instructs the elevator shaft state output unit 130B to output the elevator shaft state to the information presentation device 300.

[0058] The captured image acquiring section 110B is configured to acquire an image captured inside the elevator shaft, similar to the captured image acquiring section 110 already described.

[0059] The sensor signal acquirer 120B is configured to acquire a sensor signal that is a result of measuring the inside of the elevator shaft, similarly to the sensor signal acquirer 120 already described.

[0060] The hoistway state output unit 130B outputs the state of the hoistway. When the non-normal operation receiving unit 140B receives a non-normal state notification, the elevator shaft state output unit 130B outputs elevator shaft state information indicating the state of the elevator shaft using the first image and the first sensor signal, and the second image and the second sensor signal. When the elevator shaft state output unit 130B receives a notification from the non-normal operation receiving unit 140B indicating that a non-normal state notification has been received, it obtains, for each position of the elevator car, the state of the elevator shaft above the elevator car using a first image and a first sensor signal, and obtains the state of the elevator shaft below the elevator car using a second image and a second sensor signal, and outputs elevator shaft state information that combines the respective states for each position of the elevator car.

[0061] An example of processing by the elevator shaft monitoring device 100B according to the second embodiment will be described. FIG. 8 is a flowchart showing an example of processing of the elevator shaft monitoring device 100B according to the second embodiment of the present disclosure. The process shown in FIG. 8 corresponds to a shaft monitoring method for monitoring a shaft, which is a space in an elevator where an elevator car ascends and descends, using the shaft monitoring device 100B. When the shaft monitoring device 100B receives a command to start shaft monitoring processing from a control (not shown), for example, the shaft monitoring device 100B starts the processing shown in FIG.

[0062] First, the elevator shaft monitoring device 100B executes a captured image acquisition process (step ST2110). In the captured image acquisition process, the captured image acquisition unit 110B of the elevator shaft monitoring device 100B acquires a first image from the first imaging device 210 and acquires a second image from the second imaging device 230, similar to the captured image acquisition process already described. The captured image acquisition unit 110B outputs the acquired first image and second image to the elevator shaft state output unit 130B.

[0063] Next, the shaft monitoring device 100B executes a sensor signal acquisition process (step ST2120). In the sensor signal acquisition process, the sensor signal acquisition unit 120B of the elevator shaft monitoring device 100B acquires a first sensor signal from the first sensor device 220 and acquires a second sensor signal from the second sensor device 240, similar to the sensor signal acquisition process already described. The sensor signal acquirer 120B outputs the acquired first sensor signal and second sensor signal to the shaft state output unit 130B.

[0064] Next, the elevator shaft monitoring device 100B executes a non-normal state determination process (step ST2130). In the non-normal state determination process, the elevator shaft state output unit 130B of the elevator shaft monitoring device 100B determines that the elevator is in a non-normal state when the non-normal operation receiving unit 140B has received a non-normal state notification indicating that the elevator is in a non-normal state that is not in a normal operating state.

[0065] If the shaft state output unit 130B of the shaft monitoring device 100B determines in the non-normal state determination process (step ST2130) that the state is not abnormal (step ST2130 "NO"), it proceeds to the process of step ST2110 and repeatedly executes the processes from step ST2110 onwards.

[0066] If the shaft state output unit 130B of the shaft monitoring device 100B determines that the state is non-normal in the non-normal state determination process (step ST2130) (step ST2130 "YES"), then it executes a shaft state output process (step ST2140). When the non-normal operation receiving unit 140B receives a non-normal state notification, the elevator shaft state output unit 130B outputs elevator shaft state information indicating the state of the elevator shaft using the first image and the first sensor signal, and the second image and the second sensor signal. The elevator shaft state output unit 130B outputs, to the information presentation device 300, elevator shaft state information indicating the state of the elevator shaft.

[0067] After executing the shaft state output process (step ST2140), the shaft monitoring device 100B ends the process shown in FIG.

[0068] With the above configuration, the elevator shaft monitoring device 100B can output an elevator shaft state that would be required in an abnormal state when the elevator is not in a normal operating state. Also, the elevator shaft monitoring device B can support the work of the worker in the elevator abnormal state.

[0069] The present disclosure further discloses a shaft monitoring device having the following configuration. The elevator further includes an abnormal operation receiving unit that receives an abnormal state notification indicating that the elevator is in an abnormal state that is not a normal operation state, When the non-normal operation reception unit receives a non-normal state notification, the elevator shaft state output unit outputs elevator shaft state information indicating a state of the elevator shaft by using the first image and the first sensor signal, and the second image and the second sensor signal. A shaft monitoring device comprising: As a result, the present disclosure has the effect of providing an elevator shaft monitoring device that makes it possible to output the state of an elevator shaft that would be required in a non-normal state when the elevator is not in a normal operating state. Furthermore, the present disclosure achieves the same effects as those described above by applying the above configuration to the elevator shaft monitoring method or the above program.

[0070] Embodiment 3 In the third embodiment, a mode that makes it possible to present changes in the elevator shaft will be described. In the description of the third embodiment, the same contents as those already described in the first and second embodiments may be omitted as appropriate.

[0071] An example of the configuration of an elevator monitoring system 1C including an elevator shaft monitoring device 100C, which is a configuration in which an elevator shaft monitoring device according to the third embodiment is applied to the elevator monitoring system 1, will be described. FIG. 9 is a diagram showing an example of a configuration of an elevator monitoring system 1C including an elevator shaft monitoring device 100C according to the third embodiment of the present disclosure. The elevator monitoring system 1C differs from the elevator monitoring systems 1A and 1B already described in that it indicates changes in an elevator shaft. The elevator monitoring system 1C shown in Figure 9 is configured to include an elevator shaft monitoring device 100C, a first imaging device 210, a first sensor device 220, a second imaging device 230, a second sensor device 240, an elevator car position acquisition device 250, and an information presentation device 300.

[0072] The first imaging device 210, the first sensor device 220, the second imaging device 230, the second sensor device 240, the elevator car position acquisition device 250, and the information presentation device 300 are each configured to have functions similar to those of the first imaging device 210, the first sensor device 220, the second imaging device 230, the second sensor device 240, the elevator car position acquisition device 250, and the information presentation device 300 already described.

[0073] The hoistway monitoring device 100C differs from the hoistway monitoring devices 100A and 100B already described in that it outputs a change in the hoistway compared to the normal state of the hoistway. The elevator shaft monitoring device 100C shown in FIG. 9 includes an image acquisition unit 110C, a sensor signal acquisition unit 120C, an elevator shaft state output unit 130C, a state memory unit 150C, a normal state acquisition unit 153C, and a change information output unit 155C.

[0074] The captured image acquiring section 110C is configured to acquire an image captured inside the elevator shaft, similar to the captured image acquiring section 110 or the captured image acquiring section 110B already described.

[0075] The sensor signal acquirer 120C is configured to acquire a sensor signal that is a result of measuring the inside of the elevator shaft, similarly to the sensor signal acquirer 120 or the sensor signal acquirer 120B already described.

[0076] The hoistway state output unit 130C is configured to output the state of the hoistway based on the image and the sensor signal, similar to the hoistway state output unit 130 already described. The hoistway state output unit 130C according to this embodiment outputs hoistway state information indicating the state of the hoistway to the state storage unit 150C for storage.

[0077] The state storage unit 150C receives the hoistway state information output by the hoistway state output unit 130C, and stores and accumulates the hoistway state information indicating the state of the hoistway for each position of the hoistway car.

[0078] The normal state acquisition unit 153C acquires the normal state of the elevator shaft. Specifically, the normal state acquisition unit 153C acquires normal state information indicating the normal state of the hoistway. The normal hoistway condition is the condition within the hoistway during which the hoist car is capable of normal operation. The normal state information is, for example, information that is set and stored in advance, on the state of the elevator shaft during normal operation in the past. Alternatively, the normal state information is information derived from the normal state using, for example, past shaft state information stored in the state storage unit 150C. In this case, the normal state acquisition unit 153C acquires the past shaft state information stored in the state storage unit 150C, derives the normal state using the acquired shaft state information, and generates normal state information indicating the normal state.

[0079] The change information output unit 155C outputs the change compared to the normal state in the hoistway. The change information output unit 155C uses the normal state and the shaft state information to output shaft change information indicating the amount or degree of change in the shaft state indicated in the shaft state information. The change information output unit 155C calculates the amount of change or the degree of change by using a difference value or degree of difference between the normal state indicated in the normal state information and the shaft state indicated in the shaft state information. The change information output unit 155C outputs the calculated elevator shaft change information to the information presentation device 300.

[0080] With this configuration, the elevator shaft monitoring device 100C outputs elevator shaft change information to the information presentation device 300.

[0081] An example of processing by the elevator shaft monitoring device 100C according to the third embodiment will be described. FIG. 10 is a flowchart showing an example of processing of the elevator shaft monitoring device 100C according to the third embodiment of the present disclosure. The process shown in FIG. 10 corresponds to a shaft monitoring method for monitoring a shaft, which is a space in an elevator where an elevator car ascends and descends, using the shaft monitoring device 100C. When the elevator shaft monitoring device 100C receives a command to start the elevator shaft monitoring process from, for example, a control unit (not shown), the elevator shaft monitoring device 100C starts the process shown in FIG.

[0082] First, the elevator shaft monitoring device 100C executes a captured image acquisition process (step ST3110). In the captured image acquisition process, the captured image acquisition unit 110C of the elevator shaft monitoring device 100C acquires a first image from the first imaging device 210 and acquires a second image from the second imaging device 230, similar to the captured image acquisition process already described. The captured image acquisition unit 110C outputs the acquired first image and second image to the shaft state output unit 130C.

[0083] Next, the shaft monitoring device 100C executes a sensor signal acquisition process (step ST3120). In the sensor signal acquisition process, the sensor signal acquisition unit 120C of the elevator shaft monitoring device 100C acquires a first sensor signal from the first sensor device 220 and acquires a second sensor signal from the second sensor device 240, similar to the sensor signal acquisition process already described. The sensor signal acquirer 120C outputs the acquired first sensor signal and second sensor signal to the shaft state output unit 130C.

[0084] Next, the shaft monitoring device 100C executes a shaft state output process (step ST3130). In the shaft state output processing, the shaft state output unit 130C of the shaft monitoring device 100C outputs shaft state information indicating the state of the shaft using a first image and a first sensor signal, as well as a second image and a second sensor signal, similar to the shaft state output unit 130 already described.

[0085] Next, the shaft monitoring device 100C executes a state storage process (step ST3140). In the state storage process, the shaft state output unit 130C of the shaft monitoring device 100C outputs shaft state information indicating the state of the shaft to the state storage unit 150C for storage. The state storage unit 150C stores hoistway state information.

[0086] Next, the shaft monitoring device 100C executes a normal state acquisition process (step ST3150). In the normal state acquisition process, the normal state acquisition unit 153C of the shaft monitoring device 100C acquires the normal state of the shaft. The normal state acquisition unit 153C acquires, for example, past shaft state information stored in the state storage unit 150C. The normal state acquisition unit 153C derives a normal state using the acquired shaft state information. The normal state acquisition unit 153C regards, for example, the state of the shaft in the latest normal operation state before changing to a non-normal state as the normal state. In addition, the normal state acquisition unit 153C regards, for example, the average state of the shaft state in the normal operation state before changing to a non-normal state for a predetermined period as the normal state. The normal state acquisition unit 153C acquires normal state information indicating a normal state by generating it. Normal state acquisition unit 153C outputs the normal state information to change information output unit 155C.

[0087] Next, the elevator shaft monitoring device 100C executes a change information output process (step ST3160). In the change information output process, the change information output unit 155C of the shaft monitoring device 100C uses the normal state and the shaft state information to output shaft change information indicating the amount or degree of change in the shaft state indicated in the shaft state information. The change information output unit 155C calculates the amount of change or the degree of change by using a difference value or degree of difference between the normal state indicated in the normal state information and the shaft state indicated in the shaft state information. The change information output unit 155C outputs the calculated elevator shaft change information to the information presentation device 300. The information display device 300 displays the change in the elevator shaft based on the elevator shaft change information output by the change information output unit 155C. For example, the information display device 300 displays an image in which the amount or degree of change is superimposed for each position in the elevator shaft on an image (a first image and a second image) of the inside of the elevator shaft.

[0088] Next, the elevator shaft monitoring device 100C ends the process shown in FIG. Alternatively, the elevator shaft monitoring device 100C may proceed to step ST3110 and repeatedly execute the processes from step ST3110.

[0089] With the above configuration, the hoistway monitoring device can indicate changes in the state of the hoistway with high accuracy. In addition, the elevator shaft monitoring device can enable real-time monitoring, measurement data collection, and measurement data analysis based on highly accurate information with improved accuracy compared to conventional technology.

[0090] The present disclosure further discloses a shaft monitoring device having the following configuration. A normal state acquisition unit that acquires a normal state of the elevator shaft; a change information output unit that outputs shaft change information indicating a change amount or a change degree of the shaft state indicated by the shaft state information, using the normal state and the shaft state information; The elevator monitoring device comprises: As a result, the present disclosure has the effect of providing an elevator shaft monitoring device that is capable of indicating changes in the state of an elevator shaft with high accuracy using highly accurate information that is more accurate than conventional technology. Furthermore, the present disclosure achieves the same effects as those described above by applying the above configuration to the elevator shaft monitoring method or the above program.

[0097] The hoistway state output unit 130D is configured to output the state of the hoistway based on the image and the sensor signal, similarly to the hoistway state output unit 130 or the hoistway state output unit 130C already described. The hoistway state output unit 130D outputs hoistway state information indicating the state of the hoistway to the state storage unit 150D for storage.

[0098] The state storage unit 150D receives the shaft state information output by the shaft state output unit 130D, and stores and accumulates the shaft state information indicating the state of the shaft for each position of the elevator car.

[0099] The structure output unit 160D outputs the structure of the hoistway using the hoistway state information. The structure output unit 160D uses the hoistway state information output by the hoistway state output unit 130D to output hoistway structure information that represents the structure of the hoistway. The hoistway structure information is information for representing the structure within the hoistway, calculated using hoistway state information for each position of the hoistway car. The structure output unit 160D outputs the elevator shaft structure information to the information presentation unit.

[0100] With this configuration, the elevator shaft monitoring device 100D outputs elevator shaft structure information to the information presentation device 300.

[0101] A processing example of the elevator shaft monitoring device 100D according to the fourth embodiment will be described. FIG. 12 is a flowchart showing an example of processing of the elevator shaft monitoring device 100D according to the fourth embodiment of the present disclosure. The process shown in FIG. 12 corresponds to a shaft monitoring method for monitoring a shaft, which is a space in an elevator where an elevator car ascends and descends, using the shaft monitoring device 100D. When the shaft monitoring device 100D receives a command to start a shaft monitoring process from, for example, a control unit (not shown), the shaft monitoring device 100D starts the process shown in FIG.

[0102] First, the elevator shaft monitoring device 100D executes a captured image acquisition process (step ST4110).

FIG. 13 is a diagram showing an example of a configuration of an elevator monitoring system 1E including an elevator shaft monitoring device 100E according to the fifth embodiment of the present disclosure. Elevator monitoring system 1E differs from elevator monitoring system 1A, elevator monitoring system 1B, elevator monitoring system 1C, and elevator monitoring system 1D already described in that it indicates whether normal operation is possible in a non-normal state, such as an emergency stop state or a test operation state. The elevator monitoring system 1E shown in Figure 13 is configured to include an elevator shaft monitoring device 100E, a first imaging device 210, a first sensor device 220, a second imaging device 230, a second sensor device 240, an elevator car position acquisition device 250, and an information presentation device 300.

[0112] The first imaging device 210, the first sensor device 220, the second imaging device 230, the second sensor device 240, the elevator car position acquisition device 250, and the information presentation device 300 are each configured to have functions similar to those of the first imaging device 210, the first sensor device 220, the second imaging device 230, the second sensor device 240, the elevator car position acquisition device 250, and the information presentation device 300 already described.

[0113] The elevator shaft monitoring device 100E differs from the elevator shaft monitoring device 100A, the elevator shaft monitoring device 100B, the elevator shaft monitoring device 100C, and the elevator shaft monitoring device 100D already described in that it outputs information indicating whether normal operation is possible in a non-normal state, such as an emergency stop state or a test operation state. The elevator shaft monitoring device 100E shown in Figure 13 is configured to include an image acquisition unit 110E, a sensor signal acquisition unit 120E, an elevator shaft state output unit 130E, a non-normal operation reception unit 140E, a state memory unit 150E, a normal state acquisition unit 153E, a change information output unit 155E, and an operation feasibility determination unit 170E.

[0114] The captured image acquisition unit 110E is configured to acquire an image captured inside the elevator shaft, similar to the captured image acquisition unit 110, the captured image acquisition unit 110B, the captured image acquisition unit 110C, or the captured image acquisition unit 110D already described.

[0115] The sensor signal acquisition unit 120E is configured to acquire a sensor signal that is the result of measuring the inside of the elevator shaft, similar to the sensor signal acquisition unit 120, the sensor signal acquisition unit 120B, the sensor signal acquisition unit 120C, or the sensor signal acquisition unit 120D already described.

[0116] The hoistway state output unit 130E is configured to output the state of the hoistway based on an image and a sensor signal, similar to the hoistway state output unit 130, the hoistway state output unit 130C, or the hoistway state output unit 130D already described. The hoistway state output unit 130E outputs hoistway state information indicating the state of the hoistway to the state storage unit 150E for storage.

[0117] The non-normal operation receiving unit 140E receives information that the elevator is not in a normal operation state. The non-normal operation receiving unit 140E receives a non-normal state notification indicating that the elevator is in a non-normal state that is not a normal operating state. The non-normal state is when the elevator is not in a normal operating state, but in an emergency stop state or a test operation state. The emergency stop state is a state in which the elevator stops normal operation due to the effects of a disaster such as an earthquake. The emergency stop state is intended to be a state in which, for example, when the shaking caused by an earthquake falls below a predetermined level, workers or the like conduct a pre-check before working in the elevator shaft to confirm whether normal operation is possible. The test operation state is a state in which the elevator is stopped from normal operation and a test operation is performed by an operator or the like.

[0118] Similar to the status memory unit 150C already described, the status memory unit 150E accepts the shaft status information output by the shaft status output unit 130E, and stores and accumulates the shaft status information indicating the status of the shaft for each position of the elevator car.

[0119] The normal state acquiring unit 153E acquires the normal state of the hoistway, similarly to the normal state acquiring unit 153C already described.

[0120] Similar to the change information output unit 155C already described, the change information output unit 155E uses the normal state and the shaft state information to output shaft change information indicating the amount of change or degree of change in the shaft state indicated in the shaft state information.

[0121] The operation feasibility determination unit 170E outputs a determination result as to whether the elevator is capable of normal operation based on the elevator shaft change information. The operation feasibility determination unit 170E uses the elevator shaft change information output by the change information output unit 155E to output operation feasibility information indicating whether the elevator is operable or not. The operation feasibility determination unit 170E outputs operation feasibility information indicating that operation is possible when the amount of change or degree of change indicated in the elevator shaft change information does not exceed a preset and stored tolerance threshold, and outputs operation feasibility information indicating that operation is not possible when the amount of change or degree of change indicated in the elevator shaft change information exceeds a preset and stored tolerance threshold.

[0122] With this configuration, the elevator shaft monitoring device 100E outputs operation availability information to the information presentation device 300.

[0123] An example of processing by the elevator shaft monitoring device 100E according to the fifth embodiment will be described. FIG. 14 is a flowchart showing an example of processing of the elevator shaft monitoring device 100E according to the fifth embodiment of the present disclosure. The process shown in FIG. 14 corresponds to a shaft monitoring method for monitoring a shaft, which is a space in an elevator where a car ascends and descends, using the shaft monitoring device 100E. When the elevator shaft monitoring device 100E receives a command to start an elevator shaft monitoring process from, for example, a control unit (not shown), the elevator shaft monitoring device 100E starts the process shown in FIG.

[0124] First, the elevator shaft monitoring device 100E executes a captured image acquisition process (step ST5110). In the captured image acquisition process, the captured image acquisition unit 110E of the elevator shaft monitoring device 100E acquires a first image from the first imaging device 210 and acquires a second image from the second imaging device 230, similar to the captured image acquisition process already described. The captured image acquisition unit 110E outputs the acquired first image and second image to the elevator shaft state output unit 130E.

[0125] Next, the shaft monitoring device 100E executes a sensor signal acquisition process (step ST5120). In the sensor signal acquisition process, the sensor signal acquisition unit 120E of the elevator shaft monitoring device 100E acquires a first sensor signal from the first sensor device 220 and acquires a second sensor signal from the second sensor device 240, similar to the sensor signal acquisition process already described. The sensor signal acquirer 120E outputs the acquired first sensor signal and second sensor signal to the shaft state output unit 130E.

[0126] Next, the shaft monitoring device 100E executes a shaft state output process (step ST5130). In the shaft state output processing, the shaft state output unit 130E of the shaft monitoring device 100E, similar to the shaft state output unit 130 already described, outputs shaft state information indicating the state of the shaft using a first image and a first sensor signal, as well as a second image and a second sensor signal.

[0127] Next, the shaft monitoring device 100E executes a state storage process (step ST5140). In the state storage process, the shaft state output unit 130E of the shaft monitoring device 100E outputs shaft state information indicating the state of the shaft to the state storage unit 150E for storage. The state storage unit 150E stores shaft state information.

[0128] Next, the elevator shaft monitoring device 100E executes a non-normal state determination process (step ST5150). In the non-normal state determination process, the elevator shaft state output unit 130E of the elevator shaft monitoring device 100E determines that the elevator is in a non-normal state when the non-normal operation receiving unit 140E has received a non-normal state notification indicating that the elevator is in a non-normal state (emergency stop state or test operation state) that is not a normal operation state.

[0129] If the elevator shaft monitoring device 100E determines in the non-normal state determination process (step ST5150) that the state is not a non-normal state (emergency stop state or test operation state) (step ST5150 "NO"), it proceeds to processing of step ST5110 and repeats the processing from step ST5110.

[0130] If the elevator shaft monitoring device 100E determines in the non-normal state determination process (step ST5150) that it is in a non-normal state (emergency stop state or test operation state) (step ST5150 "YES"), it then executes a normal state acquisition process (step ST5160). In the normal state acquisition process, the normal state acquisition unit 153E of the shaft monitoring device 100E acquires the normal state of the shaft.

[0131] The elevator shaft monitoring device 100E then executes a change information output process (step ST5170). In the change information output process, the change information output unit 155E of the shaft monitoring device 100E uses the normal state and the shaft state information to output shaft change information indicating the amount or degree of change in the shaft state indicated in the shaft state information. The change information output unit 155E outputs the elevator shaft change information to the operation feasibility determination unit 170E.

[0132] The elevator shaft monitoring device 100E then executes an operation feasibility determination process (step ST5180). In the operation feasibility determination process, the operation feasibility determination unit 170E of the elevator shaft monitoring device 100E uses the elevator shaft change information output by the change information output unit 155E to output operation feasibility information indicating whether the elevator is operable or not. The operation feasibility determination unit 170E outputs operation feasibility information indicating that operation is permitted when the amount of change or the degree of change indicated in the elevator shaft change information does not exceed a preset and stored allowable threshold value. The operation feasibility determination unit 170E outputs operation feasibility information indicating that operation is not possible when the amount of change or the degree of change indicated in the elevator shaft change information exceeds a preset and stored allowable threshold value. The operation propriety determination unit 170E outputs the operation propriety information to the information presentation device 300.

[0133] The elevator shaft monitoring device 100E then ends the process shown in FIG. Alternatively, the elevator shaft monitoring device 100E may proceed to step ST5110 and repeatedly execute the process from step ST5110.

[0134] With the above configuration, the elevator shaft monitoring device 100E can further perform preliminary checks for restarting operation in the event of a disaster, etc. For example, in the event of an emergency stop due to an earthquake, etc., it becomes possible to perform a preliminary inspection using highly accurate information before a person enters the elevator shaft to perform a visual inspection. Specifically, when an earthquake occurs, elevators stop at the nearest floor and cease operation. Normally, maintenance personnel (workers) check the safety of the elevator shaft before resuming operation. By using this elevator shaft monitoring device 100E, it is possible to make a primary decision on whether to resume operation (such as returning to operation in the event of a medium-sized earthquake). Moreover, with the above-described configuration, the elevator shaft monitoring device 100E can further enable real-time monitoring, measurement data collection, and measurement data analysis.

[0135] The present disclosure further discloses a shaft monitoring device having the following configuration. The non-normal state is a state in which the elevator is not in a normal operating state, but is a state in which the elevator is stopped in an emergency (emergency stop state) or a state in which the elevator is operated on a trial basis (trial operation state), an operation possibility determination unit that outputs operation possibility information indicating whether the elevator is operable or not, using the elevator shaft change information output by the change information output unit; The elevator monitoring device comprises: As a result, the present disclosure has the effect of providing an elevator shaft monitoring device that is capable of indicating with high accuracy whether normal operation is possible, using highly accurate information that is more accurate than conventional technology. Furthermore, the present disclosure achieves the same effects as those described above by applying the above configuration to the elevator shaft monitoring method or the above program.

[0136] Embodiment 6 The sixth embodiment will explain a form that can be used in an abnormal state such as an elevator undergoing maintenance and inspection. In the description of the sixth embodiment, the same contents as those already described in the first, second, third, fourth, and fifth embodiments may be omitted as appropriate.

[0137] An example of the configuration of an elevator monitoring system 1F including an elevator shaft monitoring device 100F, which is a configuration in which the elevator shaft monitoring device according to the sixth embodiment is applied to an elevator monitoring system, will be described. FIG. 15 is a diagram showing an example of the configuration of an elevator monitoring system 1F including an elevator shaft monitoring device 100F according to the sixth embodiment of the present disclosure. Elevator monitoring system 1F differs from elevator monitoring system 1A, elevator monitoring system 1B, elevator monitoring system 1C, elevator monitoring system 1D, and elevator monitoring system 1E already described in that it presents images that show changes in the condition of the elevator shaft in non-normal conditions, such as maintenance and inspection conditions. The elevator monitoring system 1F shown in Figure 15 is configured to include an elevator shaft monitoring device 100F, a first imaging device 210, a first sensor device 220, a second imaging device 230, a second sensor device 240, an elevator car position acquisition device 250, and an information presentation device 300.

[0138] The first imaging device 210, the first sensor device 220, the second imaging device 230, the second sensor device 240, the elevator car position acquisition device 250, and the information presentation device 300 are each configured to have functions similar to those of the first imaging device 210, the first sensor device 220, the second imaging device 230, the second sensor device 240, the elevator car position acquisition device 250, and the information presentation device 300 already described.

[0139] The elevator shaft monitoring device 100F differs from the elevator shaft monitoring device 100A, the elevator shaft monitoring device 100B, the elevator shaft monitoring device 100C, and the elevator shaft monitoring device 100D already described in that it outputs images that show changes in the state of the elevator shaft in non-normal conditions, such as maintenance and inspection conditions. The elevator shaft monitoring device 100F shown in Figure 15 is configured to include an image acquisition unit 110F, a sensor signal acquisition unit 120F, an elevator shaft status output unit 130F, a non-normal operation reception unit 140F, a status memory unit 150F, a normal status acquisition unit 153F, a change information output unit 155F, and a status change image output unit 180F.

[0140] The captured image acquisition unit 110F is configured to acquire images captured inside the elevator shaft, similar to the captured image acquisition unit 110, the captured image acquisition unit 110B, the captured image acquisition unit 110C, the captured image acquisition unit 110D, or the captured image acquisition unit 110E already described.

[0141] The sensor signal acquisition unit 120F is configured to acquire a sensor signal that is the result of measuring the inside of the elevator shaft, similar to the sensor signal acquisition unit 120, the sensor signal acquisition unit 120B, the sensor signal acquisition unit 120C, the sensor signal acquisition unit 120D, or the sensor signal acquisition unit 120E already described.

[0142] The hoistway state output unit 130F is configured to output the state of the hoistway based on an image and a sensor signal, similar to the hoistway state output unit 130, the hoistway state output unit 130C, the hoistway state output unit 130D, or the hoistway state output unit 130E already described. The hoistway state output unit 130F outputs hoistway state information indicating the state of the hoistway to the state storage unit 150F for storage.

[0143] The non-normal operation receiving unit 140F receives information that the elevator is not in a normal operation state. The non-normal operation receiving unit 140E receives a non-normal state notification indicating that the elevator is in a non-normal state that is not a normal operating state. The non-normal state is when the elevator is not in a normal operating state but is undergoing maintenance and inspection. The maintenance inspection state is a state in which the elevator is undergoing maintenance and normal operation is stopped. The maintenance inspection state is assumed to be a state in which, for example, a worker or the like performs a pre-inspection before working in the elevator shaft.

[0144] Similar to the already described state memory unit 150C or state memory unit 150E, the state memory unit 150F accepts the shaft state information output by the shaft state output unit 130F, and stores and accumulates the shaft state information indicating the state of the shaft for each position of the elevator car.

[0145] The normal state acquiring unit 153F acquires the normal state of the elevator shaft, similarly to the normal state acquiring unit 153C or the normal state acquiring unit 153E already described.

[0146] Similar to the change information output unit 155C or the change information output unit 155E already described, the change information output unit 155F uses the normal state and the elevator shaft state information to output elevator shaft change information indicating the amount of change or degree of change in the elevator shaft state indicated in the elevator shaft state information.

[0147] The state change image output section 180F outputs an image showing a change in the state of the hoistway. The state change image output unit 180F uses the elevator shaft change information output by the change information output unit 155F to output a presentation image that shows the amount or degree of change superimposed on an image of the elevator shaft.

[0148] With this configuration, the elevator shaft monitoring device 100F outputs a presentation image to the information presentation device 300.

[0149] An example of processing by the elevator shaft monitoring device 100F according to the sixth embodiment will be described. FIG. 16 is a flowchart showing an example of the processing of the elevator shaft monitoring device 100F according to the sixth embodiment of the present disclosure. The process shown in FIG. 16 corresponds to a shaft monitoring method for monitoring a shaft, which is a space in an elevator where an elevator car ascends and descends, using the shaft monitoring device 100F. When the shaft monitoring device 100F receives a command to start shaft monitoring processing from, for example, a control unit (not shown), the shaft monitoring device 100F starts the processing shown in FIG.

[0150] The elevator shaft monitoring device 100F first executes a captured image acquisition process (step ST6110). In the captured image acquisition process, the captured image acquisition unit 110F of the elevator shaft monitoring device 100F acquires a first image from the first imaging device 210 and acquires a second image from the second imaging device 230, similar to the captured image acquisition process already described. The captured image acquisition unit 110F outputs the acquired first image and second image to the shaft state output unit 130F.

[0151] Next, the shaft monitoring device 100F executes a sensor signal acquisition process (step ST6120). In the sensor signal acquisition process, the sensor signal acquisition unit 120F of the elevator shaft monitoring device 100F acquires a first sensor signal from the first sensor device 220 and acquires a second sensor signal from the second sensor device 240, similar to the sensor signal acquisition process already described. The sensor signal acquirer 120F outputs the acquired first sensor signal and second sensor signal to the shaft state output unit 130F.

[0152] Next, the shaft monitoring device 100F executes a shaft state output process (step ST6130). In the shaft state output processing, the shaft state output unit 130F of the shaft monitoring device 100F outputs shaft state information indicating the state of the shaft using a first image and a first sensor signal, as well as a second image and a second sensor signal, similar to the shaft state output unit 130 already described.

[0153] Next, the shaft monitoring device 100F executes a state storage process (step ST6140). In the state storage process, the shaft state output unit 130F of the shaft monitoring device 100F outputs shaft state information indicating the state of the shaft to the state storage unit 150E for storage. The state storage unit 150F accumulates shaft state information.

[0154] Next, the elevator shaft monitoring device 100F executes a non-normal state determination process (step ST6150). In the non-normal state determination process, the elevator shaft state output unit 130F of the elevator shaft monitoring device 100F determines that the elevator is in a non-normal state (maintenance inspection state) when the non-normal operation receiving unit 140F has received a non-normal state notification indicating that the elevator is in a non-normal state (maintenance inspection state) that is not a normal operating state.

[0155] If the elevator shaft monitoring device 100F determines in the non-normal state determination process (step ST6150) that the state is not a non-normal state (maintenance inspection state) (step ST6150 "NO"), it proceeds to the process of step ST6110 and repeats the process from step ST6110.

[0156] When it is determined that the elevator shaft monitoring device 100F is in a non-normal state (maintenance inspection state) in the non-normal state determination process (step ST6150) ("YES" in step ST6150), the elevator shaft monitoring device 100F executes a normal state acquisition process (step ST6160). In the normal state acquisition process, the normal state acquisition unit 153F of the shaft monitoring device 100F acquires the normal state of the shaft.

[0157] Next, the elevator shaft monitoring device 100F executes a change information output process (step ST6170). In the change information output process, the change information output unit 155E of the shaft monitoring device 100F uses the normal state and the shaft state information to output shaft change information indicating the amount or degree of change in the shaft state indicated in the shaft state information. The change information output unit 155F outputs the elevator shaft change information to the status change image output unit 180F.

[0158] Next, the shaft monitoring device 100F executes a state change image output process (step ST6180). In the status change image output processing, the status change image output unit 180F of the elevator shaft monitoring device 100F uses the elevator shaft change information output by the change information output unit 155F to output a presentation image that shows the amount of change or the degree of change superimposed on an image of the elevator shaft.

[0159] The elevator shaft monitoring device 100F then ends the process shown in FIG. Alternatively, the elevator shaft monitoring device 100F may proceed to step ST6110 and repeatedly execute the process from step ST6110.

[0160] With the above configuration, the elevator shaft monitoring device 100F can further use highly accurate information with improved accuracy compared to conventional techniques to output an image that represents a change in the state of the elevator shaft with high accuracy. During maintenance and inspection, maintenance personnel climb onto the top of the elevator car and check the safety of the elevator shaft. By providing information about the condition of the elevator shaft before the maintenance personnel begin work, maintenance personnel can be provided with information and maintenance time can be reduced. In addition, the elevator shaft monitoring device 100F enables real-time monitoring, measurement data collection, and measurement data analysis.

[0161] The present disclosure further discloses a shaft monitoring device having the following configuration. The non-normal state is a state in which the elevator is not in a normal operating state and maintenance and inspection of the elevator is being performed (maintenance and inspection state), a state change image output unit that outputs a presentation image showing an amount of change or a degree of change superimposed on an image of the elevator shaft, using the elevator shaft change information output by the change information output unit; The elevator monitoring device comprises: As a result, the present disclosure has the effect of providing an elevator shaft monitoring device that makes it possible to present changes in the state of an elevator shaft with high accuracy using highly accurate information that is more accurate than conventional technology. Furthermore, the present disclosure achieves the same effects as those described above by applying the above configuration to the elevator shaft monitoring method or the above program.

[0162] Embodiment 7 The seventh embodiment describes a form that can be used in an abnormal state, such as updating equipment in an elevator or repairing equipment in an elevator. In the explanation of embodiment 7, content that is similar to the content already explained in embodiment 1, embodiment 2, embodiment 3, embodiment 4, embodiment 5, and embodiment 6 may be omitted as appropriate.

[0163] An example of the configuration of an elevator monitoring system 1G including an elevator shaft monitoring device 100G, which is a configuration in which the elevator shaft monitoring device according to the seventh embodiment is applied to an elevator monitoring system, will be described. FIG. 17 is a diagram showing an example of a configuration of an elevator monitoring system 1G including an elevator shaft monitoring device 100G according to the seventh embodiment of the present disclosure. Elevator monitoring system 1G differs from elevator monitoring system 1A, elevator monitoring system 1B, elevator monitoring system 1C, elevator monitoring system 1D, elevator monitoring system 1E, and elevator monitoring system 1F already described in that it indicates the state of the elevator shaft structure in non-normal conditions, such as a renewal and renovation state. The elevator monitoring system 1G shown in Figure 17 is configured to include an elevator shaft monitoring device 100G, a first imaging device 210, a first sensor device 220, a second imaging device 230, a second sensor device 240, an elevator car position acquisition device 250, and an information presentation device 300.

[0164] The first imaging device 210, the first sensor device 220, the second imaging device 230, the second sensor device 240, the elevator car position acquisition device 250, and the information presentation device 300 are each configured to have functions similar to those of the first imaging device 210, the first sensor device 220, the second imaging device 230, the second sensor device 240, the elevator car position acquisition device 250, and the information presentation device 300 already described.

[0165] The elevator shaft monitoring device 100G differs from the elevator shaft monitoring devices 100A, 100B, 100C, 100D, and 100F already described in that it outputs information representing the state of the elevator shaft structure in non-normal conditions, such as an updated and renovated state. The elevator shaft monitoring device 100G shown in Figure 17 is configured to include an image acquisition unit 110G, a sensor signal acquisition unit 120G, an elevator shaft status output unit 130G, a non-normal operation reception unit 140G, a status memory unit 150G, and a structure output unit 160G.

[0166] The captured image acquisition unit 110G is configured to acquire images captured inside the elevator shaft, similar to the captured image acquisition unit 110, the captured image acquisition unit 110B, the captured image acquisition unit 110C, the captured image acquisition unit 110D, the captured image acquisition unit 110E, or the captured image acquisition unit 110F already described.

[0167] The sensor signal acquirer 120G is configured to acquire a sensor signal which is the result of measuring the inside of the elevator shaft, similar to the sensor signal acquirer 120, the sensor signal acquirer 120B, the sensor signal acquirer 120C, the sensor signal acquirer 120D, the sensor signal acquirer 120E, or the sensor signal acquirer 120F already described.

[0168] The hoistway state output unit 130G is configured to output the state of the hoistway based on an image and a sensor signal, similar to the hoistway state output unit 130, the hoistway state output unit 130C, the hoistway state output unit 130D, the hoistway state output unit 130E, or the hoistway state output unit 130F already described. The hoistway state output unit 130G outputs hoistway state information indicating the state of the hoistway to the state storage unit 150G for storage.

[0169] The non-normal operation receiving unit 140G receives information that the elevator is not in a normal operation state. The non-normal operation receiving unit 140G receives a non-normal state notification indicating that the elevator is in a non-normal state that is not a normal operating state. A non-normal state refers to a state in which the elevator is not in normal operation but is undergoing renewal and repair checks. The update / repair confirmation state (update equipment confirmation state) is a state in which the elevator equipment is being updated and the elevator is not in normal operation. The update / repair confirmation state is assumed to be, for example, a state in which a worker or the like performs a pre-check before working in the elevator shaft to check the updated equipment and the elevator shaft (a state in which the structure of the elevator shaft is checked). The update / repair confirmation state (repair equipment confirmation state) is a state in which the elevator is being repaired and normal operation of the elevator is stopped. The update / repair confirmation state is assumed to be, for example, a state in which a worker or the like performs a pre-check before working in the elevator shaft to check the repaired equipment and the elevator shaft (a state in which the structure of the elevator shaft is checked).

[0170] Similar to the already-described state memory unit 150C, state memory unit 150E, or state memory unit 150F, state memory unit 150G accepts the shaft state information output by the shaft state output unit 130G, and stores and accumulates the shaft state information indicating the state of the shaft for each position of the elevator car.

[0171] The structure output unit 160G outputs the structure of the hoistway using the hoistway state information. The structure output unit 160G uses the hoistway state information output by the hoistway state output unit 130G to output hoistway structure information that represents the structure of the hoistway. The hoistway structure information is information for representing the structure within the hoistway, calculated using hoistway state information for each position of the hoistway car. When the non-normal operation receiving unit 140G receives a non-normal state notification, the structure output unit 160G outputs elevator shaft structure information that represents the structure of the elevator shaft, using the elevator shaft state information output by the elevator shaft state output unit 130G. The structure output unit 160G outputs the elevator shaft structure information to the information presentation device 300.

[0172] With this configuration, the elevator shaft monitoring device 100G outputs elevator shaft structure information to the information presentation device 300.

[0173] A processing example of the elevator shaft monitoring device 100G according to the seventh embodiment will be described. FIG. 18 is a flowchart showing an example of the process of the elevator shaft monitoring device 100G according to the seventh embodiment of the present disclosure. The process shown in FIG. 18 corresponds to a shaft monitoring method for monitoring a shaft, which is a space in an elevator where an elevator car ascends and descends, using the shaft monitoring device 100G. When the shaft monitoring device 100G receives a command to start shaft monitoring processing from a control (not shown), for example, the shaft monitoring device 100G starts the processing shown in FIG.

[0174] The elevator shaft monitoring device 100G first executes a captured image acquisition process (step ST7110). In the captured image acquisition process, the captured image acquisition unit 110G of the elevator shaft monitoring device 100G acquires a first image from the first imaging device 210 and acquires a second image from the second imaging device 230, similar to the captured image acquisition process already described. The captured image acquisition unit 110E outputs the acquired first image and second image to the elevator shaft state output unit 130E.

[0175] Next, the shaft monitoring device 100G executes a sensor signal acquisition process (step ST7120). In the sensor signal acquisition process, the sensor signal acquisition unit 120G of the elevator shaft monitoring device 100G acquires a first sensor signal from the first sensor device 220 and acquires a second sensor signal from the second sensor device 240, similar to the sensor signal acquisition process already described. The sensor signal acquirer 120G outputs the acquired first sensor signal and second sensor signal to the shaft state output unit 130G.

[0176] Next, the shaft monitoring device 100G executes a shaft state output process (step ST7130). In the shaft state output processing, the shaft state output unit 130G of the shaft monitoring device 100G outputs shaft state information indicating the state of the shaft using a first image and a first sensor signal, as well as a second image and a second sensor signal, similar to the shaft state output unit 130 already described.

[0177] Next, the shaft monitoring device 100G executes a state storage process (step ST7140). In the state storage process, the shaft state output unit 130G of the shaft monitoring device 100G outputs shaft state information indicating the state of the shaft to the state storage unit 150G for storage. The state storage unit 150G stores shaft state information.

[0178] Next, the elevator shaft monitoring device 100G executes a non-normal state determination process (step ST7150). In the non-normal state determination process, the elevator shaft state output unit 130G of the elevator shaft monitoring device 100G determines that the elevator is in a non-normal state (update and repair confirmation state) when the non-normal state notification indicating that the elevator is in a non-normal state (update and repair confirmation state) that is not a normal operating state has been received by the non-normal operation reception unit 140G.

[0179] If the elevator shaft monitoring device 100G determines in the non-normal state determination process (step ST7150) that the state is not a non-normal state (update / repair confirmation state) (step ST7150 "NO"), it proceeds to the processing of step ST7110 and repeats the processing from step ST7110.

[0180] Next, if the elevator shaft monitoring device 100G determines in the non-normal state determination process (step ST7150) that it is in a non-normal state (update / repair confirmation state) (step ST7150 "YES"), it executes a structure output process (step ST7160). In the structure output processing, when the non-normal operation reception unit 140G receives a non-normal state notification, the structure output unit 160G of the elevator shaft monitoring device 100G outputs elevator shaft structure information representing the structure of the elevator shaft using the elevator shaft state information output by the elevator shaft state output unit 130G.

[0181] The elevator shaft monitoring device 100G then ends the process shown in FIG. Alternatively, the elevator shaft monitoring device 100G may proceed to step ST7110 and repeatedly execute the process from step ST7110.

[0182] With the above configuration, the elevator shaft monitoring device 100G can represent the state of the elevator shaft structure with high accuracy by using highly accurate information with improved accuracy compared to conventional techniques. When modernizing (updating or renovating equipment), it is necessary to check the position and dimensions of the machinery and fixtures in the elevator. Normally, a surveyor stands on top of the elevator car and measures with a measuring device, but this can be dangerous work. Also, to ensure the safety of the surveyor when taking measurements, the elevator car is operated at a slow speed. By measuring with this elevator monitoring device, a surveyor is not required. It can also be used for a first judgment when considering the need for modernization (making an estimate). With the above configuration, the elevator shaft monitoring device 100G can enable real-time monitoring, measurement data collection, and measurement data analysis.

[0183] The present disclosure further discloses a shaft monitoring device having the following configuration. The non-normal state is a state in which the elevator is not in a normal operating state and the structure of the elevator shaft is confirmed (a structure confirmation state), When the non-normal operation reception unit receives a non-normal state notification, the structure output unit outputs elevator shaft structure information representing a structure of the elevator shaft, using the elevator shaft state information output by the elevator shaft state output unit.

As a result, the present disclosure has the effect of providing an elevator shaft monitoring device that makes it possible to represent the state of the elevator shaft structure with high accuracy using highly accurate information that is more accurate than conventional technology. Furthermore, the present disclosure achieves the same effects as those described above by applying the above configuration to the elevator shaft monitoring method or the above program.
