Description

  Embodiments described herein relate generally to a maintenance work support apparatus and a maintenance work support method.

  Conventionally, as a technology for supporting elevator maintenance work, a portable terminal held by the worker at the time of maintenance work is used to notify the worker of work procedures and precautions of the maintenance work by voice, text, video, etc. Are known. There is also an attempt to secure the safety of the worker by obtaining state data such as the on / off state of the safety switch and permitting the work when the safety is confirmed. In this specification, “maintenance work” includes not only work such as elevator adjustment and part replacement, but also inspection work for determining whether adjustment or part replacement is necessary.

  By the way, an operator who performs a series of maintenance work on the elevator car usually operates by moving the car operation switch provided on the car so that the car can be moved to an easy-to-work height. Doing work. However, in this method, the operator moves the basket using the car top operation switch, visually checks whether the height of the basket is easy to work, and fine-tunes the basket position as necessary. Operation is required, and the operator's operation is complicated. There is also a concern that the basket may move to an unexpected position due to an operator's mistaken operation.

  In addition, when an earthquake occurs while the worker is performing maintenance work on the basket, it takes time for the worker to evacuate from the basket, which makes it difficult to ensure the safety of the worker. For this reason, it is possible to easily and accurately move the basket when performing maintenance work on the basket, and to enable workers to evacuate quickly from the top of the basket in the event of an earthquake, making maintenance work more efficient and safe. There is a need for a mechanism that can improve safety.

When the basket 1 is landed, the hold door 8 is opened, so that the user gets into the basket 1 from the landing or gets off from the basket 1 to the landing. In FIG. 1, only one hold door 8 is shown for simplification, but the hold door 8 is provided at the landing on each floor where the car 1 is landing. In addition, hall halls operated by passengers at the halls are provided at halls on each floor. The hall call device is connected to the control panel 6 by wire or wirelessly, and a hall call signal is sent from the hall call device to the control panel 6 as needed.

  The space below the lowest floor in the hoistway 5 is called a pit. In the pit, an earthquake detector 9 is provided together with a safety device such as a shock absorber. The earthquake detector 9 is connected to the control panel 6 by wire or wireless, and sends an earthquake detection signal to the control panel 6 when an earthquake occurs. The hoistway 5 is provided with markers 10 at regular intervals in the height direction. The marker 10 is configured using, for example, an RFID (Radio Frequency Identifier) tag that records height information. In this case, the height of the cage 1 in the hoistway 5 can be known by reading the marker 10 with a tag reader provided in the cage 1. The control panel 6 controls the operation of the car 1 while always grasping the height (car position) of the car 1.

  FIG. 2 is a perspective view showing the inside of the basket 1. The basket 1 has a basket door 11 that opens and closes in conjunction with the above-described hold door 8. In the vicinity of the car door 11, there are provided a car operation button 12 for a user in the car 1 to perform a car call operation, a switch box 13 containing a switch operated by a worker performing maintenance work, and the like. It has been. The switch box 13 is closed during normal operation so that a general user cannot operate the switch. An identification label 14 for identifying the elevator is provided on the door of the switch box 13. As the identification label 14, for example, a QR code (registered trademark) obtained by encoding the identification information of the elevator can be used. In this case, the elevator can be identified by photographing the identification label 14 with an arbitrary camera and reading the identification information of the elevator.

  The maintenance work support device 100 of the present embodiment supports the maintenance work of the elevator configured as described above, and in particular, realizes the efficiency of the maintenance work performed on the car 1. For example, as shown in FIG. 1, the maintenance work support apparatus 100 is realized by a portable terminal that is carried or worn by a worker who performs maintenance work on the basket 1 (hereinafter referred to as “worker on the basket”). For example, the portable terminal may be one in which dedicated software (maintenance support program) is installed in an information processing apparatus such as a general-purpose smartphone, tablet terminal, or wearable terminal, or dedicated information in which a maintenance support program is incorporated in advance. It may be a processing device.

  Note that the configuration of the elevator described above is merely an example, and the configuration of the elevator to be subjected to maintenance work is not limited to this example. For example, in the above-described example, the configuration in which the height (cage position) of the cage 1 is detected by reading the marker 10 provided in the hoistway 5 is exemplified. Other methods such as a method using a signal of an encoder provided and a method of using a pulse signal of a pulse generator provided in a speed governor may be detected alone or in combination. Further, in the above-described example, the configuration in which the identification label 14 using a QR code or the like is provided on the door of the switch box 13 in the basket 1 is illustrated, but the place where the identification label 14 is provided is arbitrary. In the above-described example, the configuration in which the elevator is identified by reading the identification information encoded in the QR code or the like is illustrated, but the configuration in which the elevator is identified by another method may be used. Moreover, although the traction type elevator was illustrated in the above-mentioned example, the elevator which becomes the object of the maintenance work is not limited to the traction type, and various types of elevators can be the object of the maintenance work.

As described above, the maintenance work support device 100 is realized by the cooperation of the hardware of the portable terminal possessed or worn by the basket worker W and the software (maintenance support program) installed in the portable terminal. .

  FIG. 3 is a block diagram illustrating a hardware configuration example of the maintenance work support apparatus 100. For example, as shown in FIG. 3, the maintenance work support apparatus 100 includes a CPU 101 that controls the operation of the entire apparatus by executing a maintenance support program, a RAM 102 that is used as a work area of the CPU 101, and an initial program that is used to drive the CPU 101. The program ROM 103 storing the above, the communication I / F 104 for performing wireless communication with the outside of the apparatus such as the control panel 6, the maintenance support program executed by the CPU 101, and various data used by the maintenance support program are stored. An SSD (Solid State Drive) 106 that reads and writes various data to and from the flash memory 105 according to the control of the flash memory 105 and the CPU 101, a display 107 such as a liquid crystal display, and the display 1 according to the control of the CPU 101 The display controller 108 for controlling the operation of 07, the touch panel 109 for detecting the touch operation by the basket worker W, the touch panel controller 110 for controlling the operation of the touch panel 109 according to the control of the CPU 101, and capturing the signal corresponding to the touch operation, The camera module 111 for photographing and a camera I / F 112 for controlling the operation of the camera module 111 according to the control of the CPU 101 and for capturing the photographed image are provided.

  Note that the hardware configuration of the maintenance work support apparatus 100 shown in FIG. 3 is merely an example, and at least a part of the hardware may be changed to other hardware having an equivalent function, or other than the above Other hardware may be added. For example, instead of the touch panel 109 that detects the touch operation of the worker on the basket W, or in addition to the touch panel 109, a microphone is provided. It may be configured to detect an operation by the upper worker W. Further, in place of or in addition to the display 107 provided in the maintenance work support apparatus 100, in addition to the display 107, it is used by being attached to a transmissive eyeglass-type display worn by the basket worker W or glasses worn by the basket worker W. A configuration may be employed in which a small display or the like is connected to the maintenance work support apparatus 100 and information is displayed on these displays.

  The above-described maintenance support program is stored in, for example, the flash memory 105, and is read onto the RAM 102 and executed under the control of the CPU 101. The maintenance support program is downloaded from the outside by communication using a network and installed in the flash memory 105, for example. The maintenance support program may be provided by being stored in a computer-readable recording medium such as various optical disks, magnetic disks, and semiconductor memories, and installed in the flash memory 105. The maintenance support program may be stored in advance in the flash memory 105, the program ROM 103, or the like as an embedded program. The memory for storing the maintenance support program is not limited to the flash memory 105, and may be an EEPROM (Electrically Erasable and Programmable ROM), an HD (Hard Disk), or the like.

  FIG. 4 is a block diagram illustrating a functional configuration example of the maintenance work support apparatus 100. As shown in FIG. 4, the maintenance work support apparatus 100 includes an elevator identification unit 21, a work information acquisition unit 22, and a process specification unit as functional components realized by executing the above-described maintenance support program. 25, a basket movement amount calculation unit 26, an input reception unit 27, and a basket movement control unit 28. In addition, the maintenance work support device 100 includes a property specification DB 23 and a prescribed work DB 24 as databases constructed using the flash memory 105. The property specification DB 23 and the prescribed work DB 24 may be built in the flash memory 105 in advance, or may be built by downloading necessary data together with the maintenance support program. Further, the property specification DB 23 and the prescribed work DB 24 may be constructed outside the maintenance work support apparatus 100, and the external property specification DB 23 and the prescribed work DB 24 may be referred to as necessary.

  The elevator identification unit 21 identifies an elevator to be subjected to maintenance work. The identification of the elevator that is the object of the maintenance work can be realized, for example, by photographing the above-described identification label 14 by the camera module 111 according to the maintenance support program and reading the identification information encoded in a QR code or the like. In addition, the structure which identifies the elevator used as the object of maintenance work by methods other than image | photographing the identification label 14 with the camera module 111 may be sufficient as the elevator identification part 21. The elevator identification information identified by the elevator identification unit 21 is passed to the work information acquisition unit 22.

  The work information acquisition unit 22 refers to the property specification DB 23 and the prescribed work DB 24, and obtains work information related to the prescribed maintenance work corresponding to the property specification of the elevator identified by the elevator identification unit 21. The work information includes at least an execution order of a plurality of processes included in the prescribed maintenance work and information on a cage position suitable for the execution of each process. The property specification DB 23 stores the correspondence between the identification information of the elevator and the property specifications of the elevator (for example, model, elevating speed, installation floor, express zone, etc.). The prescribed work DB 24 stores work information related to prescribed maintenance work required for the elevator of the property specification for each property specification of the elevator.

  For example, the work information acquisition unit 22 searches the property specification DB 23 using the identification information of the elevator identified by the elevator identification unit 21 as a key, thereby specifying the property specification of the elevator that is the object of the maintenance work. And the work information acquisition part 22 acquires the work information corresponding to the elevator used as the object of a maintenance work by searching the prescription | regulation work DB24 by using the specified property specification as a key. The work information acquired by the work information acquisition unit 22 is passed to the basket movement amount calculation unit 26. Further, using the work information acquired by the work information acquisition unit 22, for example, a maintenance support screen for enabling an interactive operation of the on-car worker W is generated. Details of a specific example of the maintenance support screen will be described later.

  The process specifying unit 25 specifies the current process being performed by the on-car worker W among a plurality of processes included in the prescribed maintenance work corresponding to the elevator to be subjected to the maintenance work. The current process performed by the basket worker W can be specified based on, for example, an explicit operation of the basket worker W on a maintenance support screen described later. Specifically, when a list of a plurality of processes included in the prescribed maintenance work is displayed on the maintenance support screen, the current process performed by the on-car worker W is selected from the list. By this explicit operation, it is possible to specify the current process being performed by the on-car worker W.

  In addition, the current process performed by the on-car worker W is, for example, installed separately on the camera module 111 included in the maintenance work support device 100 according to the maintenance support program, or on the car 1 or in the hoistway 5. You may carry out by imaging | working a working condition etc. with a camera and analyzing the image. In this case, for example, a specific gesture of the cage worker W corresponding to each process is photographed and stored before the maintenance work is started, and the specific gesture is detected from an image photographed during the actual work. Thus, the current process being performed by the basket worker W may be specified. Information on the current process specified by the process specifying unit 25 is passed to the basket movement amount calculating unit 26.

  Based on the work information acquired by the work information acquisition unit 22 and the information on the current process specified by the process specification unit 25, the basket movement amount calculation unit 26 is currently implemented by the on-car worker W. It is determined whether or not the height of the cage 1 suitable for performing the work is different between the process and the next process performed after the process. Then, when the height of the car 1 suitable for execution differs between the current process and the next process, a car position signal indicating the height of the current car 1 is acquired from the control panel 6 and the current car 1 is A movement amount for moving the car 1 from the height to the height of the car 1 suitable for the next process is calculated. The movement amount of the car 1 calculated by the car movement amount calculation unit 26 is passed to the car movement control unit 28.

  The input receiving unit 27 receives an operation input from the on-car worker W on a maintenance support screen described later. For example, as described above, when the operator on the basket W performs an operation of selecting the current process from the list of processes displayed on the maintenance support screen, the input receiving unit 27 is operated by the worker on the basket W. An operation input is received, and an operation signal indicating the selected process is passed to the process specifying unit 25. When the on-car operator W performs an operation for requesting automatic driving as a response to the inquiry about the necessity of automatic driving of the car 1 on the maintenance support screen, the input receiving unit 27 performs an operation input by the on-car worker W. And an operation signal indicating a response requesting the automatic operation of the car 1 is passed to the car movement control unit 28.

  In the present embodiment, it is assumed that the on-car worker W performs various operations on the maintenance work support apparatus 100 using a maintenance support screen to be described later. Accordingly, the configuration may be such that the instruction and response of the on-basket worker W to the maintenance work support apparatus 100 are received. In this case, the input receiving unit 27 inputs the utterance voice of the worker on the basket W through the microphone, and passes an operation signal obtained by voice recognition of the uttered voice to the process specifying unit 25 and the basket movement control unit 28.

  When the movement amount of the cage 1 is calculated by the cage movement amount calculation unit 26, the basket movement control unit 28 determines whether the automatic operation of the basket 1 is necessary or not, for example, through a maintenance support screen described later. Inquire. Then, the car movement control unit 28 automatically operates the car 1 based on the movement amount calculated by the car movement amount calculation unit 26 when there is a response requesting the automatic operation of the car 1 from the worker W on the car. The control command to be transmitted is transmitted to the control panel 6 by wireless communication, for example. In this case, the control panel 6 controls the operation of the hoisting machine 4 in accordance with a control command from the basket movement control unit 28 and moves the basket 1 by the movement amount calculated by the basket movement amount calculation unit 26. Thereby, the cage 1 is automatically operated so that the height of the cage 1 becomes a height suitable for performing the work of the next process. If the occurrence of an earthquake is detected by the earthquake detector 9 while the car 1 is automatically operated, the movement of the car 1 is stopped by the control of the control panel 6.

  In addition, when the occurrence of an earthquake is detected by the earthquake detector 9 and the earthquake detection signal output from the earthquake detector 9 is input via the control panel 6 or directly from the earthquake detector 9, For example, the operator on the basket W is inquired about the necessity of rescue operation through a maintenance support screen described later. And the basket movement control part 28 transmits the control instruction | command of rescue operation to the control panel 6, for example by radio | wireless communication, when there exists a response which requests | requires rescue operation from the worker W on the cage. In the rescue operation here, in order to rescue the worker W on the cage, the cage 1 is set so that the height on the cage 1 becomes the position of the floor surface of the nearest floor (the floor closest to the current position of the cage 1). (Hereinafter, this is referred to as “cage rescue operation”). When the control command for the rescue operation on the cage is transmitted, the control panel 6 controls the operation of the hoisting machine 4 according to the control command from the cage movement control unit 28, and the height on the cage 1 is the closest. The basket 1 is moved so as to be positioned on the floor surface of the floor. Thereby, the basket worker W can evacuate from the top of the basket 1 to the nearest floor.

  In the present embodiment, it is assumed that the maintenance work support apparatus 100 is configured as a single apparatus, but the maintenance work support apparatus 100 does not necessarily have to be configured as a single apparatus, and a plurality of apparatuses are included. A combined configuration may also be used. In this case, the functional components described above are realized by being distributed to a plurality of devices, and the functions of the maintenance work support device 100 described above are realized as a whole by transmitting necessary information between the plurality of devices. The

  Next, a specific operation example of the maintenance work support apparatus 100 according to the present embodiment will be described assuming an example in which maintenance work by the basket worker W is supported while displaying the maintenance support screen. The maintenance support screen is a screen for enabling an interactive operation of the on-car worker W. Mainly, the maintenance screen is displayed when the maintenance work support device 100 is started, and the work information acquisition unit 22 performs maintenance work. The process list screen displayed in response to the acquisition of work information corresponding to the elevator that is the target of the earthquake, and the earthquake notification screen displayed when an earthquake occurs. These maintenance support screens are displayed on the display 107 under the control of the CPU 101 and the display controller 108 based on the maintenance support program, for example. Further, the operation of the basket worker W on the maintenance support screen displayed on the display 107 is detected by the touch panel 109, and an operation signal corresponding to the operation is transmitted from the touch panel controller 110 to the CPU 101.

  FIG. 5 is a diagram illustrating an example of a maintenance support screen. FIG. 5A illustrates an example of an initial screen 210 displayed when the maintenance work support device 100 is activated. FIG. 5B illustrates a maintenance work performed by the work information acquisition unit 22. 7 shows an example of a process list screen 220 that is displayed first when work information corresponding to an elevator that is the target of the acquisition is acquired. FIG. An example of the process list screen 230 displayed when the process is specified is shown.

  The initial screen 210 shown in FIG. 5A is a message that prompts the on-car operator W to photograph the identification code 14 using the camera module 111 and read the identification information, for example, “QR code in the basket”. Please read "message 211. When the worker on the basket W reads the identification information according to the message 211, the elevator identification unit 21 identifies the elevator that is the object of the maintenance work, and the work information acquisition unit 22 acquires the work information corresponding to the elevator. The

  When the work information corresponding to the elevator that is the object of the maintenance work is acquired by the work information acquisition unit 22, the maintenance support screen displayed on the display 107 is changed from the initial screen 210 illustrated in FIG. The process transitions to the process list screen 220 illustrated in (b). The process list screen 220 includes a process list 221 in which a plurality of processes included in the prescribed maintenance work are arranged according to the execution order of each process, and whether the basket 1 is moved to a height suitable for performing the first process. A message 222 for inquiring of the car operator W about whether or not, an “automatic operation” button 223 operated by the car worker W when requesting the automatic operation of the car 1, and a case of not requesting the automatic operation of the car 1 And a “manual operation” button 224 operated by the on-car worker W. The process list is generated based on the work information acquired by the work information acquisition unit 22.

  By referring to the process list 221 included in the process list screen 220, the on-car worker W can grasp each process of necessary maintenance work and its execution order. In addition, the work procedure of each process, notes, etc. may be displayed together with the process list 221. Further, such work procedures and precautions may be displayed only for a process designated by the basket worker W from the process list 221, for example.

  In addition, when the on-car operator W refers to the message 222 included in the process list screen 220 and operates the “automatic operation” button 223 as a response to the inquiry, the car movement amount calculation unit 26 sets the car 1 to the first. A movement amount for moving to a height suitable for carrying out the process work is calculated. Then, a control command for moving the car 1 based on the amount of movement is transmitted from the car movement control unit 28 to the control panel 6. Thereby, the cage 1 is automatically operated so that the height of the cage 1 becomes a height suitable for performing the work of the first process. On the other hand, when the car operator W operates the “manual operation” button 224, the automatic operation of the car 1 as described above is not performed. In this case, the on-car operator W moves the car 1 by a method similar to the conventional method, for example, by operating the on-car operation switch.

  Thereafter, when the current process performed by the on-car worker W is specified by the process specifying unit 25, the maintenance support screen displayed on the display 107 is displayed from the process list screen 220 illustrated in FIG. 5B. Then, the process transitions to a process list screen 230 illustrated in FIG. The process list screen 230 executes a process list 231 similar to the process list 221 of the process list screen 220 of FIG. 5B, a display 232 of the current process specified by the process specifying unit 25, and the next process. A message 233 for inquiring the operator W on the basket whether or not to move the basket 1 to a height suitable for the above and “automatic driving” similar to the “automatic driving” button 223 on the process list screen 220 in FIG. ”Button 234, a“ manual operation ”button 235 similar to the“ manual operation ”button 224 on the process list screen 220 in FIG. 5B, and the operator W on the basket operates when a series of maintenance work is completed. And “End Work” button 236.

  When the current process being performed by the on-car worker W is specified by the process specifying unit 25, the car movement amount calculating unit 26 performs the work in the current process and the next process as described above. It is determined whether or not the height of the basket 1 suitable for implementation is different, and if it is different, the movement amount of the basket 1 is calculated. The process list screen 230 illustrated in FIG. 5C is a screen example when the movement amount of the basket 1 is calculated by the basket movement amount calculation unit 26. If the movement amount of the basket 1 is not calculated, a message 233 is displayed. The process list screen 230 that does not include the “automatic operation” button 234 and the “manual operation” button 235 is displayed.

  When the basket worker W refers to the message 233 included in the process list screen 230 and operates the “automatic operation” button 234 as a response to the inquiry, it is based on the movement amount calculated by the basket movement amount calculation unit 26. Then, a control command for automatically operating the car 1 is transmitted from the car movement control unit 28 to the control panel 6. Thereby, the cage 1 is automatically operated so that the height of the cage 1 becomes a height suitable for performing the work of the next process. On the other hand, when the car operator W operates the “manual operation” button 235, the automatic operation of the car 1 as described above is not performed. In this case, the on-car operator W moves the car 1 by a method similar to the conventional method, for example, by operating the on-car operation switch. In addition, when the basket worker W operates the “work end” button 236, the automatic operation is performed up to the hall on the specific floor, and then the operation ends.

  FIG. 6 is a diagram illustrating an example of the earthquake notification screen 240 displayed when an earthquake occurs. This earthquake notification screen 240 is an earthquake detection that is output from the earthquake detector 9 when an earthquake is detected by the earthquake detector 9 while the maintenance work screen W is being displayed and the maintenance work by the on-car worker W is supported. It is a maintenance support screen displayed on the display 107 when a signal is input to the maintenance work support apparatus 100. The earthquake notification screen 240 includes a message 241 for inquiring the cage worker W whether or not the cage rescue operation is necessary together with an announcement that an earthquake has occurred, and the cage worker W when requesting the cage rescue operation. And a “manual operation” button 243 that is operated by the car operator W when the car rescue operation is not requested.

  When the worker on the basket W refers to the message 241 included in the earthquake notification screen 240 and operates the “rescue driving” button 242 as a response to the inquiry, the height on the basket 1 is the height of the floor surface of the nearest floor. A control command for the on-cage rescue operation for moving the car 1 to the position is transmitted from the car movement control unit 28 to the control panel 6. Thereby, the basket 1 moves so that the height on the basket 1 becomes the position of the floor surface of the nearest floor, and the worker W on the basket can evacuate from the top of the basket 1 to the nearest floor. On the other hand, when the car operator W operates the “manual operation” button 243, the car rescue operation as described above is not performed. In this case, the on-car operator W moves the car 1 by a method similar to the conventional method, for example, by operating the on-car operation switch.

  FIG. 7 is a flowchart illustrating an example of a processing procedure performed by the maintenance work support apparatus 100 according to the present embodiment. The operation outline of the maintenance work support apparatus 100 will be described below along the flowchart of FIG.

  First, the maintenance work support apparatus 100 displays an initial screen 210 as illustrated in FIG. 5A on the display 107, and recognizes an elevator that is a maintenance work target by reading the above-described identification label 14 (see FIG. 5A). Step S101). Then, the maintenance work support apparatus 100 refers to the property specification DB 23 to identify the property specification of the elevator recognized in step S101 (step S102), and refers to the defined work DB 24 to obtain the property specification identified in step S102. Work information relating to the corresponding prescribed maintenance work is acquired (step S103).

  Next, the maintenance work support apparatus 100 displays the process list screen 220 illustrated in FIG. 5B on the display 107 using the work information acquired in step S103 (step S104). Then, the maintenance work support apparatus 100 determines whether or not the “automatic operation” button 223 on the process list screen 220 has been pressed by the basket worker W (step S105).

  Here, when the “automatic operation” button 223 is pressed by the upper worker W (step S105: Yes), the maintenance work support apparatus 100 can move the basket 1 to a height suitable for performing the work of the first process. A movement amount for moving the car 1 is calculated (step S106), and a control command for automatically operating the car 1 is transmitted to the control panel 6 based on the movement amount calculated in step S106 (step S107). Thereby, the cage | basket | car 1 is automatically driven to the height suitable for performing the operation | work of the first process. On the other hand, when the “automatic operation” button 223 is not pressed (step S105: No), the processing of step S106 and step S107 is skipped, and the process proceeds to step S108.

  Next, the maintenance work support apparatus 100 identifies the current process being performed by the cage worker W among a plurality of processes included in the prescribed maintenance work, and displays the display 107 on FIG. 5B. The process list screen 220 as illustrated in FIG. 5 is changed to the process list screen 230 as illustrated in FIG. (Step S108). Also, the maintenance work support apparatus 100 identifies the next process to be performed next to the current process identified in step S108 based on the work information acquired in step S103 (step S109), and the current process identified in step S108. When moving from the process to the next process specified in step S109, it is determined whether or not the basket 1 needs to be moved, that is, whether or not the height of the basket 1 suitable for execution differs between the current process and the next process. (Step S110).

  Here, when it is determined that the movement of the basket 1 is necessary (step S110: Yes), the maintenance work support apparatus 100 moves the basket 1 to a height suitable for performing the work of the next process specified in step S109. The movement amount for this is calculated (step S111). Then, the maintenance work support apparatus 100 determines whether or not the “automatic operation” button 234 on the process list screen 230 displayed on the display 107 has been pressed by the basket worker W (step S112).

  Here, when the “automatic operation” button 234 is pressed by the car operator W (step S112: Yes), the maintenance work support apparatus 100 automatically operates the car 1 based on the movement amount calculated in step S111. A control command is transmitted to the control panel 6 (step S113). Thereby, the cage | basket | car 1 is automatically driven to the height suitable for performing the operation | work of the first process. On the other hand, when the “automatic operation” button 234 is not pressed (step S112: No), the process of step S113 is skipped and the process proceeds to step S114. If it is determined in step S110 that the movement of the basket 1 is not necessary (step S110: No), the processes in steps S111 to S113 are skipped, and the process proceeds to step S114.

  Thereafter, the maintenance work support apparatus 100 determines whether or not the “work end” button 236 on the process list screen 230 displayed on the display 107 has been pressed by the basket worker W (step S114). If the “work end” button 236 has not been pressed by the basket worker W (step S114: No), the process returns to step S108 and the subsequent processing is repeated. On the other hand, when the “work end” button 236 is pressed by the basket worker W (step S114: Yes), the automatic operation is performed up to the hall on the specific floor, and then the operation ends.

  FIG. 8 is a flowchart illustrating an example of a processing procedure when the maintenance work support apparatus 100 according to the present embodiment occurs during an earthquake. The series of processes shown in the flowchart of FIG. 8 is implemented as an interrupt process for the series of processes shown in the flowchart of FIG. 7, for example, when an earthquake occurs.

  When the occurrence of an earthquake is detected by the earthquake detector 9 and the earthquake detection signal output from the earthquake detector 9 is input to the maintenance work support apparatus 100, the maintenance work support apparatus 100 causes the earthquake notification as illustrated in FIG. A screen 240 is displayed on the display 107 (step S201). Then, the maintenance work support apparatus 100 determines whether or not the “rescue operation” button 242 on the earthquake notification screen 240 has been pressed by the on-car worker W (step S202).

  Here, when the “rescue operation” button 242 is pressed by the car operator W (step S202: Yes), the maintenance work support apparatus 100 transmits a control command for the car rescue operation to the control panel 6 (step S202). S203). Thereby, the basket 1 moves so that the height on the basket 1 becomes the position of the floor surface of the nearest floor, and the worker W on the basket can evacuate from the top of the basket 1 to the nearest floor. On the other hand, when the “rescue operation” button 242 is not pressed (step S202: No), the process of step S203 is skipped, and the series of processes ends.

  As described above in detail with specific examples, according to the present embodiment, the current process and the next process performed by the cage worker W among the prescribed maintenance work are performed. When the height of the suitable basket 1 is different, a movement amount for moving the basket 1 to a position suitable for performing the work of the next process is calculated. Then, when the car operator W is inquired about whether or not the car 1 needs to be automatically driven, and the car worker W has received a response requesting the car 1 to automatically run, the car 1 is determined based on the calculated movement amount. A control command to be moved is transmitted to the control panel 6. Therefore, the cage 1 can be moved easily and accurately when the on-car operator W performs the maintenance work on the cage 1, and the efficiency of the maintenance work performed on the elevator car 1 can be realized. .

  Further, according to the present embodiment, when there is an answer to the basket worker W about the necessity of the rescue operation on the cage when an earthquake occurs and there is a response requesting the rescue operation on the cage, the control command for the rescue operation on the cage is issued. It is transmitted to the control panel 6 so that the rescue operation on the basket is performed. Therefore, the operator W on the car can be appropriately evacuated from the car 1 when an earthquake occurs, and the safety of the maintenance work can be improved.

  In the above description, the amount of movement when the car 1 is automatically driven according to the request of the car operator W is the difference between the current car 1 height and the car 1 height suitable for the next process. I want to ask. However, instead of this, the difference between the current viewpoint height of the cage worker W and the viewpoint height suitable for performing the next process is calculated as the movement amount when the car 1 is automatically driven. May be. The height of the viewpoint is an approximate height of the eyes of the cage worker W who is performing maintenance work.

  In this case, the work information stored in the prescribed work DB 24 includes, as information, the height of the viewpoint suitable for performing each process, instead of the cage position suitable for performing each process included in the prescribed maintenance work. The height of the current viewpoint of the on-car worker W is, for example, the on-car work photographed by the camera module 111 provided in the maintenance work support device 100 or a camera separately installed on the car 1 or in the hoistway 5. By analyzing the face image of the worker W, the line-of-sight direction (elevation angle or depression angle) of the cage worker W is detected, and the height information of the marker 10 ahead of the cage worker W is read and read. The height information of the marker 10 can be detected by subtracting or adding the height corresponding to the line-of-sight direction of the on-car worker W.

<Second Embodiment>
Next, a second embodiment will be described. The present embodiment is an example assuming a case where a car worker W using the maintenance work support apparatus 100 performs an elevator maintenance work in cooperation with a collaborator working in the car 1. The operation when an earthquake occurs is different from that of the first embodiment. The basic configuration of the maintenance work support device 100 and the operation while the occurrence of an earthquake is not detected are the same as those in the first embodiment. Therefore, the same or corresponding components as those in the first embodiment are the same below. A redundant description will be omitted as appropriate, and only differences from the first embodiment will be described.

  FIG. 9 is a block diagram illustrating a functional configuration example of the maintenance work support apparatus 100 of the present embodiment. As shown in FIG. 9, the maintenance work support apparatus 100 of the present embodiment includes a work condition information acquisition unit 29 in addition to the configuration of the first embodiment (see FIG. 4).

  The work condition information acquisition unit 29 acquires work condition information related to the work condition of the maintenance work input by the basket worker W. The work condition information includes at least the presence / absence of a collaborator who performs work in the basket 1 and the presence / absence of a collaborator who performs work in the pit. The work condition information includes, for example, items for inputting work conditions such as the presence / absence of a collaborator and the work place of the collaborator on the initial screen 210 (see FIG. 5A) of the maintenance support screen described above. It can be obtained by adopting a configuration in which the upper worker W inputs a work condition in this item. Further, for example, the operator on the basket W inputs the work condition information in advance using the management terminal of the service center that is responsible for the maintenance work service, and the maintenance work support apparatus 100 is started from this management terminal when the maintenance work support device 100 is activated. It is good also as a structure which acquires the work condition information input in advance.

  In the maintenance work support device 100 of the present embodiment, the basket movement control unit 28 determines the presence / absence of a collaborator who performs work in the basket 1 based on the work condition information acquired by the work condition information acquisition unit 29. . When there is a collaborator who performs work in the basket 1, the basket movement control unit 28 transmits a rescue operation control command to the control panel 6 according to the response of the cage worker W when an earthquake occurs. Instead of the above-mentioned rescue command operation on the cage, the control command for the rescue operation in the cage and in the cage is transmitted to the control panel 6. The on-cage and in-cage rescue operation means that the height on the car 1 is the position of the floor of the nearest floor in order to rescue the on-car worker W and the collaborators in the car 1 in order. In this operation, after the car 1 is moved, the car 1 is moved so that the floor surface of the car 1 becomes the position of the floor surface of the nearest floor. The control panel 6 controls the operation of the hoisting machine 4 in accordance with the control command for the on-car / in-car rescue operation, and controls the operation of the car 1, so that the car operator W and the car 1 can work together. Can evacuate to the nearest floor in sequence.

  FIG. 10 is a flowchart illustrating an example of a processing procedure when the maintenance work support device 100 according to the present embodiment occurs in the event of an earthquake. The series of processes shown in the flowchart of FIG. 10 is implemented as an interrupt process for the series of processes shown in the flowchart of FIG. 7, for example, when an earthquake occurs.

  When the occurrence of an earthquake is detected by the earthquake detector 9 and the earthquake detection signal output from the earthquake detector 9 is input to the maintenance work support apparatus 100, the maintenance work support apparatus 100 causes the earthquake notification as illustrated in FIG. A screen 240 is displayed on the display 107 (step S301). Then, the maintenance work support apparatus 100 determines whether or not the “rescue operation” button 242 on the earthquake notification screen 240 has been pressed by the on-car worker W (step S302).

  Here, when the “rescue operation” button 242 is pressed by the upper worker W (step S302: Yes), the maintenance work support apparatus 100 determines whether there is a collaborator in the basket 1 based on the work condition information. It is determined whether or not (step S303). If there is a collaborator in the car 1 (step S303: Yes), the maintenance work support device 100 transmits a control command for the on-car / in-car rescue operation to the control panel 6 (step S304). Thereby, the worker on the basket W and the collaborators in the basket 1 can sequentially evacuate to the nearest floor.

  On the other hand, when there is no collaborator in the basket 1 (step S303: No), the maintenance work support device 100 transmits a control command for the on-car rescue operation to the control panel 6 (step S305). Thereby, the cage | basket worker W can evacuate to the nearest floor. If the “rescue operation” button 242 on the earthquake notification screen 240 is not pressed (step S302: No), the processing from step S303 to step S305 is skipped, and the series of processing ends.

  As described above, according to the present embodiment, when a control operator for rescue operation is transmitted to the control panel 6 in response to the response of the on-car worker W when an earthquake occurs, there is a collaborator in the car 1. Since the control command for the rescue operation in the car and in the car is transmitted, not only the car worker W but also the collaborators in the car 1 can be appropriately evacuated in the event of an earthquake. The property can be further improved.

<Third Embodiment>
Next, a third embodiment will be described. This embodiment is an example in which it is assumed that an on-car worker W who uses the maintenance work support apparatus 100 performs elevator maintenance work in cooperation with a collaborator working in a pit. The operation at the time of occurrence is different from the first embodiment and the second embodiment. Note that the basic configuration of the maintenance work support apparatus 100 and the operation while the occurrence of an earthquake is not detected are the same as those in the first embodiment and the second embodiment. Further, the functional configuration of the maintenance work support apparatus 100 is the same as that of the second embodiment shown in FIG. In the following, only differences from the first embodiment and the second embodiment will be described.

  The on-cage rescue operation for rescuing the on-cage worker W in the event of an earthquake is an operation in which the car 1 is moved so that the height on the car 1 becomes the position of the floor surface of the nearest floor, as described above. is there. For this reason, when the nearest floor is the lowest floor or a floor close to the lowest floor, the evacuation route from the pit is blocked by the cage 1 by carrying out the rescue operation on the cage, and the work is performed in the pit. There is a concern that the evacuation of joint workers will be hindered. Therefore, in the present embodiment, when there is a collaborator in the pit, and the evacuation of the collaborator in the pit is hindered by the on-cage rescue operation, the floor on which the height on the car 1 is matched. Cargo rescue operation will be carried out by changing the floor (hereinafter referred to as the “cargo top floor”) from the nearest floor to a floor that does not hinder the evacuation of co-workers in the pit.

  In the maintenance work support device 100 of the present embodiment, the basket movement control unit 28 determines the presence or absence of a collaborator who performs work in the pit based on the work condition information acquired by the work condition information acquisition unit 29. When there is a collaborator who performs work in the pit, the car movement control unit 28 transmits a control command for the rescue operation on the car to the control panel 6 according to the response of the car worker W when an earthquake occurs. In addition, it is determined whether or not the evacuation of co-workers in the pit is hindered by carrying out the rescue operation on the cage. The control command for the rescue operation on the cage that has been changed from the floor to the floor that does not inhibit the evacuation of the co-workers in the pit is transmitted to the control panel 6. The control panel 6 controls the operation of the hoist 4 according to the control command for the rescue operation on the car, and the height on the car 1 does not hinder the evacuation of the collaborators in the pit. By moving the basket 1 so as to become, it is possible to appropriately evacuate the worker W on the cage without hindering the evacuation of the collaborator in the pit.

  FIG. 11 is a flowchart illustrating an example of a processing procedure at the time of occurrence of an earthquake in the maintenance work support device 100 of the present embodiment. The series of processes shown in the flowchart of FIG. 11 is implemented as an interrupt process for the series of processes shown in the flowchart of FIG. 7, for example, when an earthquake occurs.

  When the occurrence of an earthquake is detected by the earthquake detector 9 and the earthquake detection signal output from the earthquake detector 9 is input to the maintenance work support apparatus 100, the maintenance work support apparatus 100 causes the earthquake notification as illustrated in FIG. A screen 240 is displayed on the display 107 (step S401). Then, the maintenance work support apparatus 100 determines whether or not the “rescue operation” button 242 on the earthquake notification screen 240 has been pressed by the on-car worker W (step S402).

  Here, when the “rescue operation” button 242 is pressed by the basket worker W (step S402: Yes), the maintenance work support apparatus 100 determines whether there is a collaborator in the pit based on the work condition information. Is determined (step S403). If there is a collaborator in the pit (step S403: Yes), the maintenance work support apparatus 100 may further hinder the evacuation of the collaborator in the pit due to the movement of the basket 1 to the nearest floor. It is determined whether or not there is (step S404). If there is a possibility that the evacuation of the collaborator in the pit may be hindered (step S404: Yes), the maintenance work support apparatus 100 inhibits the evacuation of the collaborative work in the pit from the nearest floor on the basket upper floor. The control command for the rescue operation on the cage changed to the floor not to be transmitted is transmitted to the control panel 6 (step S405). Thereby, the upper worker W can be appropriately evacuated without obstructing the evacuation of the collaborator in the pit.

  On the other hand, when there is no collaborator in the pit (step S403: No), or when the evacuation of the collaborator in the pit is not hindered even if the basket 1 moves to the nearest floor (step S404: No), The maintenance work support device 100 transmits a control command for normal on-car rescue operation to the control panel 6 (step S406). If the “rescue operation” button 242 on the earthquake notification screen 240 is not pressed (step S402: No), the processing from step S403 to step S406 is skipped, and the series of processing ends.

  As described above, according to the present embodiment, when the control command for the rescue operation is transmitted to the control panel 6 according to the response of the on-car operator W in the event of an earthquake, the movement of the car 1 to the nearest floor If there is a possibility that the evacuation of collaborators in the pit may be obstructed, the rescue operation control command is transferred by changing the upper floor of the basket from the nearest floor to a floor that does not inhibit the evacuation of collaborators in the pit. Therefore, the on-cage worker W can be appropriately evacuated without hindering the evacuation of the collaborator in the pit.

<Fourth Embodiment>
Next, a fourth embodiment will be described. In the present embodiment, in the event of an earthquake, the workers in the pits are appropriately linked with other portable terminals owned or worn by collaborators in the pits (hereinafter referred to as “mobile terminals for workers in the pits”). This is an example of adding an evacuation function. Note that the basic configuration of the maintenance work support apparatus 100 and the operation while the occurrence of an earthquake is not detected are the same as those in the first to third embodiments. Only the differences from the first to third embodiments will be described below.

  FIG. 12 is a block diagram illustrating a functional configuration example of the maintenance work support apparatus 100 of the present embodiment. As shown in FIG. 12, the maintenance work support apparatus 100 of the present embodiment includes an evacuation guidance control unit 30 in addition to the configurations of the second and third embodiments (see FIG. 9).

  In the maintenance work support device 100 of this embodiment, the earthquake detection signal output from the earthquake detector 9 when an earthquake occurs is input not only to the car movement control unit 28 but also to the evacuation guidance control unit 30. When the earthquake detection signal is input, the evacuation guidance control unit 30 determines the presence or absence of a collaborator who performs work in the pit based on the work condition information acquired by the work condition information acquisition unit 29. Then, when there is a collaborator working in the pit, the basket movement control unit 28 sends a control command for instructing evacuation guidance to the collaborator in the pit by, for example, wireless communication, by the collaborator in the pit. It transmits to the portable terminal 300 for workers in a pit to be used.

  FIG. 13 is a block diagram illustrating a functional configuration example of the portable terminal 300 for workers in a pit. The portable terminal 300 for workers in the pit is realized by, for example, cooperation of hardware similar to the maintenance work support apparatus 100 illustrated in FIG. 3 and dedicated software (evacuation guidance program). As functional components realized by the execution, as shown in FIG. 13, an evacuation guidance execution unit 301, an evacuation guidance determination unit 302, and a warning unit 303 are provided.

  The evacuation guidance execution unit 301, when a control command for instructing evacuation guidance to the collaborator in the pit is transmitted from the maintenance work support apparatus 100, the evacuation guidance to the collaborator in the pit is received in accordance with the control command. Execute. The evacuation guidance for the collaborator in the pit can be realized by, for example, displaying the evacuation route from the pit, the evacuation method, the cautions at the time of evacuation, or the like to the collaborator in the pit.

  The evacuation guidance determination unit 302 determines whether the collaborator in the pit is following the evacuation guidance. Whether or not the collaborator in the pit follows the evacuation guidance is determined by, for example, a camera module provided in the portable terminal 300 for workers in the pit according to the evacuation guidance program, or a camera separately installed in the pit or the hoistway 5 It can be determined by taking an image of the evacuation situation of the collaborator and analyzing the image. Also, whether or not the collaborator in the pit is following the evacuation guidance based on the presence or absence of an explicit operation (operation indicating that the evacuation guidance is being followed) on the portable terminal 300 for the pit worker by the collaborator in the pit. You may make it determine.

  The warning unit 303 outputs a warning to the collaborator in the pit when the evacuation guidance determination unit 302 determines that the collaborator in the pit does not follow the evacuation guidance. As warnings to collaborators in the pit, for example, an alarm can be sounded, a message prompting evacuation or output by voice display can be considered.

  FIG. 14 is a flowchart illustrating an example of a processing procedure at the time of occurrence of an earthquake in the maintenance work support device 100 of the present embodiment. The series of processes shown in the flowchart of FIG. 14 is implemented as an interrupt process for the series of processes shown in the flowchart of FIG. 7, for example, when an earthquake occurs.

  When the occurrence of an earthquake is detected by the earthquake detector 9 and the earthquake detection signal output from the earthquake detector 9 is input to the maintenance work support apparatus 100, the maintenance work support apparatus 100 causes the earthquake notification as illustrated in FIG. The screen 240 is displayed on the display 107 (step S501). Then, the maintenance work support apparatus 100 determines whether there is a collaborator in the pit based on the work condition information (step S502). When there is a collaborator in the pit (step S502: Yes), the maintenance work support device 100 instructs the portable terminal 300 for the pit worker to instruct evacuation guidance for the collaborator in the pit. A command is transmitted (step S503). On the other hand, when there is no collaborator in the pit (step S502: No), the process of step S503 is skipped and the process proceeds to step S504.

  Next, the maintenance work support apparatus 100 determines whether or not the “rescue operation” button 242 on the earthquake notification screen 240 has been pressed by the on-car worker W (step S504). When the “rescue operation” button 242 is pressed by the cage worker W (step S504: Yes), the maintenance work support device 100 further moves the cage 1 to the nearest floor to collaborate in the pit. It is determined whether there is a possibility that the evacuation is hindered (step S505). If there is a possibility that the evacuation of the collaborator in the pit may be hindered (step S505: Yes), the maintenance work support apparatus 100 inhibits the evacuation of the collaborative work in the pit from the nearest floor on the basket upper floor. The control command for the rescue operation on the cage changed to the floor not to be transmitted is transmitted to the control panel 6 (step S506). Thereby, the upper worker W can be appropriately evacuated without obstructing the evacuation of the collaborator in the pit.

  On the other hand, if the evacuation of the collaborator in the pit is not hindered even if the basket 1 moves to the nearest floor (step S505: No), the maintenance work support device 100 issues a control command for normal rescue operation on the basket. This is transmitted to the control panel 6 (step S507). If the “rescue operation” button 242 on the earthquake notification screen 240 is not pressed (step S504: No), the processing from step S505 to step S507 is skipped, and the series of processing ends.

  FIG. 15 is a flowchart illustrating an example of a processing procedure at the time of occurrence of an earthquake in the pit worker mobile terminal 300. When receiving the control command for instructing evacuation guidance from the maintenance work support apparatus 100 (step S601), the portable terminal 300 for workers in the pit starts evacuation guidance for the collaborators in the pit (step S602). Then, the portable terminal 300 for workers in the pit determines whether or not the collaborator in the pit follows the evacuation guidance (step S603), and if the collaborator in the pit does not follow the evacuation guidance (step S603: No), a warning is output (step S604). On the other hand, if the collaborator in the pit follows the evacuation guidance (step S603: Yes), the process of step S604 is skipped and the process proceeds to step S605.

  Thereafter, the portable terminal 300 for workers in the pit determines whether or not the evacuation guidance has ended (whether or not the evacuation of the collaborator in the pit has been completed) (step S605), and the evacuation guidance has ended. If not (Step S605: No), the process returns to Step S603 and the subsequent processing is repeated. When the evacuation guidance ends (step S605: Yes), a series of processing ends.

  As described above, according to the present embodiment, when there is a collaborator in the pit at the time of the earthquake, the in-pit worker mobile terminal 300 used by the collaborator in the pit A control command for instructing evacuation guidance to a collaborator is transmitted. The portable terminal 300 for workers in the pit performs evacuation guidance for the collaborator in the pit in response to this control command, and outputs a warning if the collaborator in the pit does not follow the evacuation guidance. ing. Therefore, not only the worker on the cage W but also the collaborator in the pit can be appropriately evacuated when an earthquake occurs, and the safety of maintenance work can be further improved.

  According to at least one of the embodiments described above, it is possible to improve the efficiency and safety of maintenance work performed on the elevator car.
