Detailed Description
Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. The maintenance inspection work support system for a passenger conveyor according to the present embodiment is intended to reliably detect an abnormality of a worker who performs a maintenance inspection work on the passenger conveyor, and to prevent an accident from occurring in advance. Hereinafter, an escalator will be described as an example of a passenger conveyor to be subjected to a maintenance inspection operation.
First, an outline of an escalator to be subjected to maintenance inspection work will be described. Fig. 1 is a view schematically showing the structure of an escalator. As shown in fig. 1, the escalator is supported by a truss 1 erected between an upper floor and a lower floor of a building. The truss 1 includes an upper truss 1a disposed at an upper floor of the building, a lower truss 1b disposed at a lower floor of the building, and a middle truss 1c disposed between the upper truss 1a and the lower truss 1 b.
The upper truss 1a is a space that becomes a machine room of the escalator, and a drive device 2, a drive sprocket 3, a control panel 4, and the like of the escalator are provided inside thereof. The driving device 2 is controlled by a control panel 4, and drives the driving sprocket 3 by transmitting power of a motor operated by power supply to the driving sprocket 3 via a driving chain 5.
On the other hand, a drive sprocket 3, a pair of driven sprockets 6, a tension adjusting device 7, and the like are provided in the lower truss 1 b. Further, a guide rail (not shown) is provided in the intermediate truss 1 c. An endless step chain 8 is wound around and suspended between the drive sprocket 3 and the driven sprocket 6, and a plurality of steps 9 are connected to the step chain 8. The tension adjusting device 7 adjusts the tension of the step chain 8 by adjusting the position of the driven sprocket 6 in a direction to approach or separate from the drive sprocket 3.
The step chain 8 rotates between the drive sprocket 3 and the driven sprocket 6 by rotating the drive sprocket 3 by driving the drive device 2. Thereby, the plurality of steps 9 connected to the step chain 8 circulate between the upper floor and the lower floor of the building along the guide rail provided in the intermediate truss 1 c.
Further, a pair of skirt guards 10 and a pair of balustrade panels 11 are disposed on the truss 1 so as to be positioned on both left and right sides of the plurality of steps 9 that circulate, and handrail belts 12 are attached to the peripheries of the pair of balustrade panels 11. The handrail belt 12 is a handrail for a passenger mounted on the steps 9 to hold, and rotates around the balustrade panel 11 in synchronization with the movement of the steps 9.
The escalator configured as described above is periodically subjected to maintenance and inspection work. The maintenance inspection work of the escalator comprises: an operation of operating the control panel 4 in the upper truss 1a to operate the escalator in the inspection operation mode and to confirm the operation of the driving device 2 and the driving sprocket 3; adjusting the tension of the step chain 8 by operating the tension adjusting device 7 in the lower truss 1 b; and an operation of removing the steps 9 from the step chain 8 on the intermediate truss 1c and inspecting the steps 9 and the guide rails.
In such maintenance and inspection work, when a worker is in an abnormal state such as a lowered level of consciousness due to, for example, a physical condition or the like, or falls down in a work place, not only the worker cannot properly perform the work, but also there is a possibility that an accident such as an influence on safety of the worker may occur. The maintenance work support system according to the present embodiment can reliably detect such an abnormality of the operator, and automatically perform such a correspondence as cutting off power supply to the escalator, operating the alarm device, or notifying an external device such as a monitoring device provided in a monitoring center, thereby preventing an accident from occurring due to the abnormality of the operator.
Fig. 2 is a diagram illustrating an abnormal state of the worker W during the maintenance operation. For example, when the worker W who enters a narrow space such as the upper truss 1a and the lower truss 1b and performs maintenance and inspection work is in a state of decreased consciousness level due to a physical condition or the like, as shown in fig. 2, the worker often takes a posture that is not taken in normal work, such as squatting while supporting both hands on the ground. In the present embodiment, the posture of the operator W is photographed by the cameras 21 provided in the upper truss 1a and the lower truss 1 b.
Since the work items required for the maintenance and inspection work of the escalator are determined, the posture that the worker W in a normal state can take during the maintenance and inspection work can be grasped to some extent in advance. In the present embodiment, the posture that the operator W can take in accordance with the work items of these maintenance inspection works is modeled in advance, and a posture model is generated. The posture model is, for example, a model obtained by collecting shape characteristics of all postures that the operator W can take in a normal state in the upper truss 1a and the lower truss 1b in a mesh manner, and is used as a comparison target of the posture of the operator W imaged by the camera 21. That is, the posture of the operator W imaged by the camera 21 is compared with the posture model, and when the shape characteristic of the posture of the operator W imaged by the camera 21 deviates from the posture model, it is determined that the operator W is in an abnormal state.
In the present embodiment, in order to improve the accuracy of abnormality determination of the operator W such as a decrease in the level of consciousness, biological information such as the pulse wave and blood pressure of the operator W detected by the biosensor may be used. That is, when the shape characteristic of the posture of the operator W imaged by the camera 21 is deviated from the posture model and the biological information of the operator W detected by the biological sensor shows an abnormal value, it is determined that the operator W is in an abnormal state. In this case, as shown in fig. 3, the worker W performs a maintenance inspection operation while mounting the biosensor 22.
Further, as shown in fig. 3, by performing the maintenance inspection work while the operator W is further equipped with the gyro sensor 23, it is possible to detect an abnormal state such as a fall of the operator W as shown in fig. 2 from the movement of the operator W detected by the gyro sensor 23. For example, when the angular velocity detected by the gyro sensor 23 exceeds a predetermined reference value, it can be determined that the operator W has fallen over.
Fig. 4 is a block diagram showing an example of a functional configuration of the maintenance inspection work support system according to the present embodiment. As shown in fig. 4, the maintenance inspection work support system of the present embodiment includes a camera 21, a storage unit 24, an abnormality determination unit 25, and a control unit 26.
As shown in fig. 2, the camera 21 is provided on the upper truss 1a and the lower truss 1b, and photographs the posture of the operator W who performs the maintenance inspection work on the upper truss 1a and the lower truss 1 b. The image data captured by the camera 21 is input to the abnormality determination unit 25 as needed.
The storage unit 24 stores the above-described posture model. The posture model is generated in advance by modeling the posture that the operator W can take in accordance with the work items of the maintenance inspection work of the escalator, and is stored in the storage unit 24.
As described above, the attitude model collects the shape characteristics of all attitudes that can be acquired by the operator W in a normal state in the upper truss 1a and the lower truss 1 b. For example, the shape characteristics of the postures can be included in the posture model for each posture that can be obtained by the operator W in the normal state in the lower truss 1b, such as the operator W in the upper truss 1a who looks directly at the control panel 4, the operator who is reaching in the direction of the control panel 4, the operator who returns in the direction of the driving device 2 and/or the driving sprocket 3, the operator who looks directly at the driving device 2 and/or the driving sprocket 3, and the operator who is reaching in the direction of the driving device 2 and/or the driving sprocket 3, and the operator W in the normal state in the lower truss 1b who looks directly at the driven sprocket 6 and/or the tension adjusting device 7 in the lower truss 1b, and the operator who reaches in the direction of the driven sprocket 6 and/or the tension adjusting device 7. The posture model may be generated from the image data obtained by capturing the posture of the operator W who performs the maintenance inspection work in the upper truss 1a and the lower truss 1b by the camera 21 in advance, or may be generated by using a Computer Graphics (CG) technique.
The abnormality determination unit 25 compares the posture of the operator W imaged by the camera 21 with the posture model stored in the storage unit 24, and determines deviation of the posture of the operator W from the posture model. For example, the deviation of the posture of the operator W from the posture model can be determined by mapping the shape feature collected by the posture model and the shape feature of the posture of the operator W captured by the camera 21 onto a common feature space. That is, when the shape feature of the posture of the operator W imaged by the camera 21 deviates from any of the shape features collected from the posture model in the feature space, it is determined that the posture of the operator W imaged by the camera 21 deviates from the posture model.
Fig. 5 is a diagram for explaining an example of a method for determining a deviation of a posture. Black circles Fr1, Fr2, Fr3, and Fr4 in the drawing respectively show the shape characteristics of the posture included in the posture model, and white circles Fp1 and Fp2 in the drawing respectively show the shape characteristics of the posture of the operator W captured by the camera 21. In the example of fig. 5, for convenience, a multidimensional feature space corresponding to a feature of a shape expressed in multiple dimensions is expressed in two dimensions.
A threshold value indicating a range of similar postures (similar range) is set for each shape characteristic of each posture included in the posture model. In the example of fig. 5, the broken lines around the features Fr1, Fr2, Fr3, Fr4 indicate threshold values set for the respective features, and the ranges surrounded by the broken lines indicate similar ranges. When the shape feature of the posture of the operator W captured by the camera 21 is mapped within a similar range to any one of the shape features of the postures included in the posture model (the feature Fr2 in the example of fig. 5) as in the feature Fp1 of fig. 5, it can be determined that the posture of the operator W captured by the camera 21 is not deviated from the posture model. On the other hand, as in the feature Fp2 of fig. 5, when the shape feature of the posture of the operator W imaged by the camera 21 is mapped to a position out of which similar range of the shape features of the respective postures included in the posture model is deviated, it is determined that the posture of the operator W imaged by the camera 21 is deviated from the posture model.
When it is determined that the posture of the operator W imaged by the camera 21 is out of the posture model, the abnormality determination unit 25 further determines whether or not biological information such as the pulse wave and the blood pressure of the operator W indicates an abnormal value.
In the present embodiment, as shown in fig. 3, an operator W who performs maintenance inspection work of the escalator is equipped with a biosensor 22 and a gyro sensor 23. The biological information of the operator W detected by the biological sensor 22 and the information indicating the angular velocity of the movement of the operator W detected by the gyro sensor 23 are wirelessly transmitted from the biological sensor 22 and the gyro sensor 23 as needed, received by the wireless receiving unit 27, and input to the abnormality determination unit 25.
The abnormality determination unit 25 determines that the worker W is in an abnormal state (for example, a state of decreased consciousness level) when it is determined that the posture of the worker W imaged by the camera 21 is out of the posture model, the biological information wirelessly transmitted from the biosensor 22 provided in the worker W and received by the wireless reception unit 27 is confirmed, and when the biological information of the worker W shows an abnormal value. In the determination as to whether or not the biological information is an abnormal value, for example, a normal range of a standard pulse wave or blood pressure is determined in advance, and when the biological information of the operator W detected by the biosensor 22 deviates from the normal range, it is determined as an abnormal value.
The abnormality determination unit 25 determines that the operator W has fallen down or the like in an abnormal state when the angular velocity indicating the movement of the operator W wirelessly transmitted from the gyro sensor 23 provided in the operator W and received by the wireless reception unit 27 exceeds a predetermined reference value even if it is determined that the posture of the operator W imaged by the camera 21 is not deviated from the posture model. When the abnormality determination unit 25 determines that the worker W is in an abnormal state, an abnormality detection signal is transmitted from the abnormality determination unit 25 to the control unit 26.
The control unit 26 cuts off power supply to the escalator when the abnormality detection signal is transmitted from the abnormality determination unit 25. As shown in fig. 4, a main power supply 31 of the escalator is connected to an input of an inverter 34 via a main power breaker 32 and a contactor (electromagnetic contactor) 33. The output of the inverter 34 is connected to a motor 35 of the drive device 2. The inverter 34 converts the electric power of the main power source 31 in accordance with an operation command from a control microcomputer in the control panel 4 in a state where the contacts of the main power breaker 32 and the contactor 33 are conductive, and drives and controls the motor 35 of the drive device 2. When the abnormality detection signal is transmitted from the abnormality determination unit 25, the control unit 26 can cut off the power supply to the escalator by, for example, cutting off the energization to the coil of the contactor 33 and switching the contact of the contactor 33 from on to off.
The control unit 26 operates the alarm device 28 when the abnormality detection signal is transmitted from the abnormality determination unit 25. The alarm device 28 is a device that generates a buzzer sound or the like for notifying an abnormality. By the operation of the alarm device, it is possible to notify other workers W, surrounding persons, and the like that the power supply of the escalator is cut off due to an abnormality of the worker W.
When the abnormality detection signal is transmitted from the abnormality determination unit 25, the control unit 26 notifies the external device 30 such as a monitoring device provided in the monitoring center that the abnormality has occurred in the operator W, for example, by message transmission via the transmission unit 29. This makes it possible to notify an operator or the like at a monitoring center that an abnormality has occurred in the operator W during maintenance and inspection work of the escalator. The external device 30 serving as the notification destination is not limited to the monitoring device of the monitoring center, and may be another device such as a mobile terminal carried by another worker W.
As described above, the maintenance inspection work for the escalator includes a work of operating the escalator in the inspection operation mode and checking whether or not various kinds of articles, such as the operation of the drive device 2 and the drive sprocket 3, function normally. The inspection operation mode is a mode in which the escalator is operated only while the worker W presses the up button and the down button. The switching from the normal operation mode to the inspection operation mode and the return from the inspection operation mode to the normal operation mode are normally performed by the operator W operating an inspection switch provided on the control panel 4, but the control unit 26 may have a function of automatically performing such switching of the operation mode.
That is, since the camera 21 provided on the upper truss 1a as the machine room of the escalator functions as a sensor for detecting the operator W in the upper truss 1a, the camera 21 provided on the upper truss 1a may be directly connected to the control unit 26. Then, the control unit 26 switches the operation mode of the escalator from the normal operation mode to the inspection operation mode when the operator W in the upper truss 1a is detected by the camera 21, and returns the operation mode of the escalator from the inspection operation mode to the normal operation mode when the operator W in the upper truss 1a is not detected by the camera 21. This can reduce the operation burden on the operator W who performs work in the upper truss 1a, and can effectively suppress a trouble that the escalator suddenly operates in the normal operation mode because the operator W forgets to operate the inspection switch, and a trouble that the escalator cannot operate in the normal operation mode after the end of the work because the operator W forgets to reset the inspection switch.
The functions of the abnormality determination unit 25 and the control unit 26 in the maintenance work support system according to the present embodiment can be realized by using a processor Circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). The functions of the abnormality determination unit 25 and the control unit 26 may be implemented as extended functions of a control microcomputer provided on the control panel 4. The function of the storage unit 24 for storing the posture model can be realized by using a storage device such as an HDD (Hard disk Drive) or an SSD (Solid State Drive).
Next, the flow of the operation of the maintenance inspection work support system according to the present embodiment will be described with reference to fig. 6. Fig. 6 is a flowchart showing an example of the operation of the maintenance inspection work support system according to the present embodiment. The maintenance inspection work support system according to the present embodiment is configured such that the worker W who performs the maintenance inspection work on the escalator starts the operation by performing some operation to start the system, such as operating a predetermined switch, when the work is started, and ends the operation when the worker W performs some operation to stop the system when the work is ended.
When the operation of the maintenance inspection work support system of the present embodiment is started, first, the abnormality determination unit 25 determines whether or not the operator W is detected by the cameras 21 provided on the upper truss 1a and the lower truss 1b (step S101). Here, when the operator W is detected by the camera 21 (yes in step S101), the abnormality determination unit 25 compares the posture of the operator W captured by the camera 21 with the posture model stored in the storage unit 24 using the image data input from the camera 21 as needed (step S102). Then, the abnormality determination unit 25 determines whether or not the posture of the operator W is separated from the posture model (step S103).
Here, when it is determined that the posture of the operator W is not deviated from the posture model (no in step S103), the process returns to step S102, and the abnormality determination unit 25 repeatedly performs the process of comparing the posture of the operator W with the posture model using the image data newly input from the camera 21. On the other hand, when determining that the posture of the operator W is out of the posture model (yes in step S103), the abnormality determination unit 25 next determines whether or not the biological information of the operator W detected by the biosensor 22 provided in the operator W shows an abnormal value (step S104).
Here, when it is determined that the biological information of the operator W does not show an abnormal value (no in step S104), the process returns to step S102, and the abnormality determination unit 25 repeatedly performs the process of comparing the posture of the operator W with the posture model using the image data newly input from the camera 21. On the other hand, when it is determined that the biological information of the operator W indicates an abnormal value (yes in step S104), the abnormality determination unit 25 determines that an abnormality such as a decrease in consciousness level occurs in the operator W, and transmits an abnormality detection signal to the control unit 26.
When the abnormality detection signal is transmitted from the abnormality determination unit 25, the control unit 26 cuts off the power supply to the escalator (step S105). The control unit 26 also activates the alarm device 28 to generate a buzzer sound or the like (step S106), and notifies the external device 30 such as a monitoring device of the monitoring center that an abnormality occurs in the operator W (step S107).
When the operator W is not detected by the camera 21 in step S101 (no in step S101), the abnormality determination unit 25 determines whether or not the angular velocity indicating the movement of the operator W detected by the gyro sensor 23 provided in the operator W exceeds a predetermined reference value (step S108). Here, when the angular velocity indicating the movement of the operator W does not exceed the reference value (no in step S108), the process returns to step S101, and the subsequent processes are repeated. On the other hand, when determining that the angular velocity indicating the movement of the operator W exceeds the reference value (yes in step S108), the abnormality determination unit 25 determines that an abnormality such as a fall has occurred in the operator W, and transmits an abnormality detection signal to the control unit 26. As a result, the control unit 26 shuts off the power supply to the escalator (step S105), operates the alarm device 28 (step S106), and notifies the external device 30 (step S107).
As described above by way of specific example and in detail, the maintenance and inspection work support system according to the present embodiment determines that an abnormality such as a decrease in the level of consciousness occurs in the operator W when the posture of the operator W imaged by the camera 21 is deviated from the posture model and the biological information of the operator W detected by the biosensor 22 shows an abnormal value, and automatically performs such a correspondence as cutting off the power supply to the escalator, operating the alarm device 28, or notifying the external device 30 such as a monitoring device provided in a monitoring center. As a result, according to the maintenance inspection work support system of the present embodiment, it is possible to reliably detect an abnormality of the operator W who performs the maintenance inspection work of the escalator, and to prevent an unexpected situation from occurring which affects the safety of the operator W.
(modification 1)
In the above embodiment, it is determined that an abnormality such as a decrease in the level of consciousness occurs in the operator W when the posture of the operator W imaged by the camera 21 deviates from the posture model and the biological information of the operator W detected by the biological sensor 22 shows an abnormal value, but it may be configured such that an abnormality occurs in the operator W when the posture of the operator W imaged by the camera 21 deviates from the posture model without using the biological information of the operator W. In this configuration, although the accuracy of detecting an abnormality of the operator W is lowered, the operator W does not need to equip the biosensor 22, and therefore the trouble of equipping the biosensor 22 can be reduced, and an advantage in terms of cost can be obtained.
(modification 2)
In the above embodiment, the gyro sensor 23 provided in the operator W detects the movement of the operator W, but may be configured to detect the movement of the operator W using image data captured by the camera 21. In this configuration, in order to detect the fall of the operator W who works on the intermediate truss 1c, it is necessary to additionally provide the camera 21 having the intermediate truss 1c as the imaging range, but the operator W does not need to equip the gyro sensor 23, and therefore, the trouble of equipping the gyro sensor 23 can be reduced, and an advantage in terms of cost can be obtained.
(modification 3)
In the above-described embodiment, the previously generated posture model is used as it is as a target of comparison of the posture of the operator W imaged by the camera 21, but it may be configured to accumulate image data when it is determined that the posture of the operator W is not deviated from the posture model, that is, image data of the camera 21 imaged with the posture of the operator W performing the work in a normal state, and update the posture model at any time using the image data. With such a configuration, the net collection degree of the posture model can be improved, and a robust determination can be achieved.
(modification 4)
In the above embodiment, the abnormality of the operator W is determined using the posture model obtained by collecting the shape feature of the posture of the operator W in the normal state in a net manner, but a posture model obtained by collecting the shape feature of the posture of the operator W in the abnormal state in a net manner may be separately generated, and when the shape feature of the posture of the operator W captured by the camera 21 is close to the feature included in the posture model, it may be determined that the operator W is in the abnormal state.
(modification 5)
In the above-described embodiment, the escalator is exemplified as an example of the passenger conveyor to be subjected to the maintenance inspection work, but the passenger conveyor to be subjected to the maintenance inspection work may be a moving walkway (moving walkway). That is, since the moving walkway has the same structure as the escalator and the maintenance and inspection work is also the same as the escalator, the present invention can be effectively applied even when the moving walkway is used as a work target.
According to the above-described embodiments and modifications, it is possible to reliably detect an abnormality of an operator and prevent an accident from occurring in the past.
Although several embodiments of the present invention have been described above, these embodiments are presented as examples, and are not intended to limit the scope of the present invention. These new embodiments can be implemented in other various forms, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and variations thereof are included in the scope and gist of the invention, and are included in the invention described in the scope of the claims and the equivalent scope thereof.
