  The car 10, the counterweight 20, and the main rope 30 are installed in the hoistway 2 of the elevator 1. The hoisting machine 40, the main sheave 50, the deflecting sheave 51, and the elevator control device 60 are installed in a machine room 3 provided above the hoistway 2.

  The car 10 is used by a user. The car 10 is installed between a pair of car guide rails (not shown) installed in the hoistway 2, and the car 10 is connected to the car guide rails via a guide device (not shown) installed at least one of the car guide rails. The inside of the hoistway 2 is raised / lowered by raising / lowering along. A car door 11 is installed on the car 10 so as to be freely opened and closed. The car door 11 closes and opens the car side entrance 12 of the car 10. The car door 11 is kept closed when the car 10 is raised and lowered, and when the car 10 is landed, the car door 11 is changed from the closed state to the open state by a driving device (not shown). The car 10 is provided with an open / close sensor (not shown) and the like, and these sensors are connected to the elevator control device 60. The open / closed state of the door D including the car door 11 and the plurality of landing doors 4 a is input to the elevator control device 60.

  The counterweight 20 moves up and down in the hoistway 2 in conjunction with the raising and lowering of the car 10. The counterweight 20 is installed between a pair of weight guide rails (not shown), and moves up and down along the weight guide rails via a guide device (not shown) installed at least one of the weight guide rails. Here, the weight of the counterweight 20 is set so as to be balanced with the car 10 with the hoisting machine 40 sandwiched when the car 10 has a predetermined load capacity (for example, about 1/2 of the maximum load capacity). Yes.

  The main rope 30 is one or more ropes connecting the car 10 and the counterweight 20, and is wound around the main sheave 50 and the baffle sheave 51 of the hoisting machine 40. The main rope 30 raises and lowers the car 10 and the counterweight 20 in a traction manner. The main rope 30 has one end connected to the car 10 and the other end connected to the counterweight 20. The main rope 30 has one end fixed to the upper part in the vertical direction of the car 10 and the other end fixed to the upper part in the vertical direction of the counterweight 20.

  The hoisting machine 40 is rotated by a motor 41 to wind up the main rope 30 wound around the main sheave 50 and changes the relative position in the ascending / descending direction of the car 10 and the counterweight 20 to raise / lower the car 10. It is moved up and down in the road 2. The hoisting machine 40 is connected to the elevator control device 60, and drive control of the motor 41 is performed by electric power supplied via the elevator control device 60.

  The building (not shown) where the elevator 1 is installed is composed of a plurality of floors. On each floor of the building, there is a landing 4 for riding the car 10 of the elevator 1. A landing door 4a is provided at each landing 4 so as to be freely opened and closed. The landing door 4a closes and opens the landing side entrance / exit 4b of the landing 4 respectively. The landing side entrance / exit 4b is formed at a position facing the car side entrance / exit 12 when the car 10 is landed.

  The landing door 4a is normally in a closed state, and its operation to the open state is restricted by a lock mechanism (not shown). The landing door 4a is unlocked by the lock mechanism and moved from the closed state to the open state in conjunction with the car 10 landing and the car door 11 operating from the closed state to the open state.

  At the landing 4, a landing operation panel 4c is installed. The landing operation panel 4 c is operated when the user calls the car 10 of the elevator 1 to the landing 4, and is connected to the elevator control device 60. The landing operation panel 4c is provided with an ascending call button, a descending call button, etc. (not shown). When the rising call button is pressed, the hall operation panel 4c performs call registration for the elevator controller 60 to call the car 10 heading to the upper floor to the hall 4 where the user is present. Further, when the lower call button is pressed, the hall operation panel 4c performs call registration for the elevator control device 60 to call the car 10 heading to the lower floor to the hall 4 where the user is present.

  The elevator control device 60 has a normal operation mode in which the car 10 is moved according to call registration, and an inspection operation mode that is used by an operator during inspection work. The operation mode confirmation device 70 confirms the operation mode of the elevator 1 with the elevator control device 60. The operation mode confirmation device 70 outputs the operation mode of the elevator 1 to the operation mode transmission device 80.

  The operation mode transmission device 80 transmits the operation mode of the elevator 1. The operation mode transmission device 80 is connected to the portable terminal 5 wirelessly such as wireless LAN or infrared communication, and transmits the operation mode of the elevator 1 output from the operation mode confirmation device 70 to the portable terminal 5.

  The mobile terminal 5 alerts the worker in advance of danger that may occur during the inspection work. The portable terminal 5 is worn when a worker works. The portable terminal 5 is, for example, a terminal device that can be attached to a helmet, a glasses-type terminal device, or the like. The portable terminal 5 includes a warning database 5a, a photographing device 5b, a mark confirmation device 5c, a danger detection device 5d, and a warning notification device 5e.

  The alert database 5a functions as a storage unit, and stores a reference image of the alert mark M and alert information (caution information) indicating matters to be noted in association with each other. For example, the alert database 5a stores a first table (not shown) composed of items of a reference image of the attention mark M, an inspection place, and a risk factor. In addition, the alert database 5a stores a second table T2 including items of inspection locations, risk factors, and alert information. By referring to the first table, the inspection location and the risk factor are specified based on the reference image of the caution mark M, and by referring to the second table T2, the alert information is based on the inspection location and the risk factor. Identified.

  The inspection place is a place where the worker inspects the elevator 1, for example, on the car 10, a pit not shown, the machine room 3, and the like. The risk factor is an item that causes a risk in the work, and includes, for example, energization, a step, and an entrainment. The alert information is information that causes the worker to be alerted, and includes, for example, an electric shock alert, a foot alert, an entanglement alert, and a safety belt / inspection switch confirmation.

  The caution mark M is formed in a certain size, and includes a first element P of the outer frame and a second element Q written in the frame of the first element P. The first element P indicates an inspection place, and the second element Q indicates a risk factor. The second element Q can be omitted. The first element P is described by a figure such as a quadrangle, a triangle, or a circle (circle). The square first element P indicates that the inspection location is the machine room 3, the triangular first element P indicates that the inspection location is a pit, and the circular first element P indicates that the inspection location is a car. 10 is shown.

  The second element Q is described by symbols such as “!”, “˜”, “∽”. The symbol “!” Indicates that the risk factor is energization, the symbol “˜” indicates that the risk factor is a step, and the symbol “∽” indicates that the risk factor is involved. As described above, the caution mark M is described by a combination of the first element P indicating the inspection place and the second element Q indicating the risk factor. When the inspection place itself becomes a risk factor, it is written only with the first element P indicating the inspection place, and the second element Q indicating the risk factor is omitted. For example, when the inspection place is on the car 10 and the car 10 itself is a risk factor, a caution mark M written only by the circular first element P is attached to the upper part of the car 10. In this case, the alert information is associated with unique information that needs to be noted on the car 10. For example, the alert information is “safety band / check switch confirmation”.

  The caution mark M is formed in a plate shape, and is attached to an inspection place or a place causing a risk by an adhesive or a magnet. For example, when the inspection place is the machine room 3, as shown in FIG. 3, the elevator control device 60 installed in the machine room 3 is attached with a caution mark M <b> 1 indicating that the machine room 3 is careful about energization. Yes. Further, a caution mark M2 indicating that the machine room 3 is careful of the step is attached to the step of the mounting table 3a on which the elevator control device 60 is mounted.

  The imaging device 5b functions as an imaging unit such as a camera and images an object in the direction of the operator's line of sight. The imaging device 5b captures a caution mark M attached to an inspection place or a location that becomes a risk factor. The imaging device 5b outputs the captured image of the captured caution mark M to the mark confirmation device 5c.

  The mark confirmation device 5c functions as a determination unit, and confirms the photographed image of the caution mark M output from the photographing device 5b. The mark confirmation device 5c compares the photographed image of the caution mark M with the reference image of the caution mark M in the first table stored in the alert database 5a, and determines whether or not they match. When the mark confirmation device 5c determines that the captured image of the caution mark M matches the reference image of the caution mark M, the mark confirmation device 5c confirms the inspection place and the risk factor corresponding to the reference image of the caution mark M, and confirms the checked inspection place and danger. The factor is output to the danger detection device 5d.

  The danger detection device 5d functions as a determination unit and a control unit, and detects alerting information based on the inspection location and the risk factor output from the mark confirmation device 5c. For example, the danger detection device 5d refers to the second table T2 of the alert database 5a and detects alert information that matches the inspection location and the risk factor. The danger detection device 5d outputs the detected alert information to the alert notification device 5e.

  The alerting notification device 5e functions as a notification unit, and notifies the alerting information to the worker at the inspection place. The alerting notification device 5e includes an augmented reality projection screen 50e and a speaker 51e (see FIG. 5). The alerting notification device 5e displays alerting information on the augmented reality projection screen 50e and outputs the alerting information from the speaker 51e. Note that the alerting notification device 5e may alert the worker by means of vibration, warning light, or the like in addition to the screen display and audio output.

  Next, an operation example of the maintenance work support apparatus according to the first embodiment will be described. FIG. 4 is a flowchart illustrating an operation example of the maintenance work support apparatus according to the first embodiment. FIG. 5 is a schematic diagram illustrating an alerting example of the maintenance work support device according to the first embodiment.

  First, the operation mode confirmation device 70 confirms whether the operation mode of the elevator control device 60 is the inspection operation mode (step S1). When the operation mode of the elevator control device 60 is the inspection operation mode (step S2; YES), the operation mode confirmation device 70 outputs the fact that it is the inspection operation mode to the operation mode transmission device 80. The operation mode transmission device 80 transmits information indicating that the operation mode is the inspection operation mode to the worker's portable terminal 5 (step S3). The portable terminal 5 confirms the attention mark M photographed by the photographing device 5b by using the mark confirmation device 5c (step S4). For example, the mark confirmation device 5c confirms the inspection locations and risk factors of the caution marks M1 and M2 photographed in the machine room 3 by the photographing device 5b.

  Next, the danger detection device 5d compares the attention mark M confirmed by the mark confirmation device 5c with the information in the alert database 5a (step S5). For example, the danger detection device 5d refers to the second table T2, compares the inspection location and risk factors of the caution mark M with the inspection location and risk factors of the alert database 5a, and checks the inspection location and danger of the caution mark M. It is determined whether or not the factor matches the inspection location and the risk factor in the alert database 5a (step S6). When the inspection location and the risk factor of the caution mark M match the inspection location and the risk factor in the alert database 5a (step S6; YES), the danger detection device 5d alerts the corresponding inspection location and risk factor. Information is output to the alerting notification device 5e.

  The alerting notification device 5e notifies the worker of alerting information corresponding to the alert mark M (step S7). For example, the alerting notification device 5e displays alerting information on the augmented reality projection screen 50e and outputs the alerting information from the speaker 51e as shown in FIG. For example, in the case of the caution marks M1 and M2, the worker is notified of the caution information (electric shock caution) corresponding to the caution mark M1 and the caution information (step caution) corresponding to the caution mark M2. After notifying the worker of the alert information, the process returns to step S1 described above.

  In step S6 described above, the danger detection device 5d determines that the inspection location and the risk factor of the caution mark M do not match the inspection location and the risk factor of the alert database 5a (step S6; NO). It returns to above-mentioned step S1 without alerting.

  Moreover, in the above-mentioned step S2, the operation mode confirmation apparatus 70 outputs the fact that it is not the inspection operation mode to the operation mode transmission apparatus 80 when the operation mode of the elevator control device 60 is not the inspection operation mode (step S2; NO). The operation mode transmission device 80 transmits to the mobile terminal 5 that it is not in the inspection operation mode. The alerting notification device 5e of the portable terminal 5 notifies the worker of a message prompting the change to the inspection operation mode (Step S8), and ends. The worker starts the inspection work after changing the operation mode of the elevator control device 60 to the inspection operation mode.

  As described above, according to the maintenance work support apparatus according to the first embodiment, the alert information corresponding to the attention mark M attached to the inspection place is notified to the worker. Thereby, even when the worker is unaware of the risk factor at the time of inspection, or when the attention is distracted, the worker can be alerted accurately. Therefore, the safety of the worker can be improved.

  Further, since the caution mark M is composed of the first element P indicating the inspection place and the second element Q indicating the risk factor, the caution mark M can be configured simply. This facilitates comparison between the captured image of the caution mark M and the reference image. Therefore, the accuracy of matching the attention mark M can be improved and the processing time can be shortened.

[Embodiment 2]
A configuration example of the maintenance work support apparatus according to the second embodiment will be described. FIG. 6 is a block diagram illustrating a configuration example of the maintenance work support apparatus according to the second embodiment. The second embodiment is different from the first embodiment in that the distance between the attention mark M attached to the inspection place and the photographing device 5b of the mobile terminal 5 is measured and the number of alerts is narrowed down based on the measurement result. In addition, the same code | symbol is attached | subjected to the component same as Embodiment 1, and detailed description is abbreviate | omitted. The same applies to other embodiments.

  As shown in FIG. 6, the portable terminal 5 includes a mark distance measuring device 5f. The mark distance measuring device 5f functions as a distance measuring unit, and measures the distance between the caution mark M attached to the inspection place and the photographic device 5b based on the photographed image of the caution mark M photographed by the photographing device 5b. . For example, the mark distance measuring device 5f measures the distance to the caution mark M from the round-trip time until the emitted light reaches the caution mark M and is reflected from the caution mark M and received (TOF (Time Of) Flight) Measurement method). The mark distance measuring device 5f measures the distance to the attention mark M when there are a plurality of captured images of the attention mark M.

  The mark distance measuring device 5f acquires the captured image of the caution mark M, the inspection location and the risk factor corresponding to the caution mark M from the mark confirmation device 5c. The mark distance measuring device 5f measures the distance from the round trip time of light in the captured image of the caution mark M to the caution mark M. The mark distance measuring device 5f outputs the inspection location and the risk factor corresponding to the attention mark M to the attention calling notification device 5e in the order of the shortest measured distance. The alerting notification device 5e notifies the alerting information by the number of thresholds in the order from the closest distance measured by the mark distance measuring device 5f.

  Next, an operation example of the maintenance work support apparatus according to the second embodiment will be described. FIG. 7 is a flowchart illustrating an operation example of the maintenance work support apparatus according to the second embodiment. When the operation mode of the elevator controller 60 is the inspection operation mode, the operation mode transmission device 80 transmits information indicating that the operation mode is the inspection operation mode to the portable terminal 5 of the worker (steps S1 to S3). The portable terminal 5 confirms the caution mark M photographed by the photographing device 5b, and compares the confirmed caution mark M with information in the alert database 5a (steps S4 and S5).

  When the inspection location and the risk factor of the attention mark M coincide with the inspection location and the risk factor of the attention alert database 5a (step S6; YES), the attention alert notification device 5e alerts the number of coincident attention marks M and the alert A threshold that is the upper limit of the number of information notifications is compared (step S21). Here, it is preferable to set the number (threshold value) notified by the alerting notification device 5e to a number that allows the worker to grasp the danger at the same time. The attention alert device 5e determines whether or not the number of attention marks M is equal to or less than a threshold value (step S22). When it is determined that the number of caution marks M is equal to or less than the threshold value (step S22; YES), the caution alert device 5e notifies the worker of caution information corresponding to all the caution marks M (step S7). Further, when the alerting notification device 5e determines that the number of the attention marks M is not less than or equal to the threshold (Step S22; NO), the alerting notification device 5e outputs the alerting information by the number of thresholds in the order of the distance measured by the mark distance measuring device 5f. Notification is made (step S23). For example, when there are two thresholds for notifying alert information, if the number of alert marks M that match the inspection location and risk factor in the alert database 5a is three, the alert notification device 5e Only two pieces of alert information are notified in order from the shortest distance measured by the distance measuring device 5f. At this time, two pieces of alert information may be notified at the same time, or alert information may be notified by shifting the time one by one in order of increasing distance.

  As described above, according to the maintenance work support device according to the second embodiment, when the number of captured images of the attention mark M exceeds the threshold value, the number of threshold values is increased in the order of the distance measured by the mark distance measurement device 5f. The alert information corresponding to the attention mark M is notified. As a result, when the number exceeds the number that allows the worker to grasp the precautions, priority can be given to the risk factor of the object that is close to the worker. Therefore, since the worker can deal with the immediate risk factor in order, the danger can be avoided reliably.

[Embodiment 3]
A configuration example of the maintenance work support apparatus according to the third embodiment will be described. FIG. 8 is a block diagram illustrating a configuration example of the maintenance work support apparatus according to the third embodiment. The third embodiment is different from the first embodiment in that when the worker recognizes the alert information, the notification of the alert information is canceled. When the worker recognizes that the alert information has been notified, the worker is to repeat the alert information aloud.

  As shown in FIG. 8, the portable terminal 5 includes a voice acquisition device 5g, a reminder recognition device 5h, and a reminder notification release device 5i. The voice acquisition device 5g acquires voice. The voice acquisition device 5g includes a microphone (not shown). The microphone is arranged, for example, at the worker's mouth and collects the worker's voice. The voice acquisition device 5g outputs the collected voice of the worker to the attention recognizing device 5h as voice data.

  The attention recognizing device 5h functions as a control unit and determines that the worker has recognized the attention. For example, the attention recognizing device 5h compares the voice data of the worker with the attention information notified from the attention notifying device 5e and determines whether or not they match. The attention recognizing device 5h outputs the determination result to the attention calling notification canceling device 5i.

  The alert notification release device 5i functions as a control unit and cancels the alert information notified from the alert notification device 5e. For example, the alert notification release device 5i notifies the alert information notified from the alert notification device 5e when the alert recognition device 5h determines that the voice data of the worker matches the alert information. To release.

  Next, an operation example of the maintenance work support apparatus according to the third embodiment will be described. FIG. 9 is a flowchart illustrating an operation example of the maintenance work support apparatus according to the third embodiment. When the operation mode of the elevator controller 60 is the inspection operation mode, the operation mode transmission device 80 transmits information indicating that the operation mode is the inspection operation mode to the portable terminal 5 of the worker (steps S1 to S3). The portable terminal 5 confirms the caution mark M photographed by the photographing device 5b, and compares the confirmed caution mark M with information in the alert database 5a (steps S4 and S5). When the inspection location and the risk factor of the caution mark M match the inspection location and the risk factor in the alert database 5a (step S6; YES), the alert notification device 5e operates the alert information corresponding to the attention mark M. The employee is notified (step S7).

  Next, the attention recognizing device 5h compares the sound data acquired by the sound acquisition device 5g with the attention information notified to the worker (step S31), and whether or not the sound data matches the attention information. Is determined (step S32). If the alerting recognition device 5h determines that the speech data acquired by the speech acquisition device 5g matches the alerting information notified to the worker (step S32; YES), the worker's speech data and the alerting information Are output to the alert notification release device 5i. When the alert notification recognition device 5h outputs that the worker's voice data matches the alert information, the alert notification releasing device 5i cancels the notification of the alert information that matches the audio data (step S33). ). Note that when the alerting recognition device 5h determines that the voice data acquired by the speech acquisition device 5g and the alerting information notified to the worker do not match (step S32; NO), the alerting recognition device 5h returns to step S31 described above. Again, the audio data acquired by the audio acquisition device 5g is compared with the alert information notified to the worker.

  As described above, according to the maintenance work support device according to the third embodiment, when the alert recognition device 5h confirms that the worker has recognized the notification of the alert information, the alert notification release device 5i The notification of the alert information by the alert notification device 5e is canceled. Thereby, the situation where the alerting information recognized when the worker inspects is continuously notified can be avoided. Moreover, since it is not necessary to cancel the alert information by manual operation by the worker, the canceling operation can be facilitated.

  Note that the method of determining that the worker has recognized the notice of alert information may be other than voice. For example, when the worker's line of sight is detected and the worker's line of sight is directed to the caution mark M, it may be determined that the worker has recognized the notice of alert information.

[Embodiment 4]
A configuration example of the maintenance work support apparatus according to the fourth embodiment will be described. FIG. 10 is a block diagram illustrating a configuration example of the maintenance work support apparatus according to the fourth embodiment. The fourth embodiment is different from the first embodiment in that the notice information is emphasized and notified when the worker does not recognize the notice information.

  As shown in FIG. 10, the portable terminal 5 includes a notification time measuring device 5j and a notification emphasizing device 5k. The notification time measuring device 5j functions as a control unit and measures the time when the alert information is notified. For example, the notification time measuring device 5j starts counting a timer after the alert notification device 5e notifies the alert information, and measures the time during which the alert information is notified. The notification time measuring device 5j outputs, to the notification emphasizing device 5k, that the fixed time has elapsed since the notification of the alerting information when the fixed time has elapsed since the timer was started.

  The notification emphasizing device 5k functions as a control unit, and emphasizes and alerts notice information. The notification emphasizing device 5k increases the volume of the alerting information output from the speaker 51e or outputs the alerting information displayed on the augmented reality projection screen 50e when the notification time measuring device 5j outputs that a certain time has elapsed. Increase the font size, change the color and font.

  Next, an operation example of the maintenance work support apparatus according to the fourth embodiment will be described. FIG. 11 is a flowchart illustrating an operation example of the maintenance work support apparatus according to the fourth embodiment. When the operation mode of the elevator controller 60 is the inspection operation mode, the operation mode transmission device 80 transmits information indicating that the operation mode is the inspection operation mode to the portable terminal 5 of the worker (steps S1 to S3). The portable terminal 5 confirms the caution mark M photographed by the photographing device 5b, and compares the confirmed caution mark M with information in the alert database 5a (steps S4 and S5). When the inspection location and the risk factor of the caution mark M match the inspection location and the risk factor in the alert database 5a (step S6; YES), the alert notification device 5e operates the alert information corresponding to the attention mark M. The employee is notified (step S7).

  Next, the attention recognizing device 5h compares the sound data acquired by the sound acquisition device 5g with the attention information notified to the worker (step S31), and whether or not the sound data matches the attention information. Is determined (step S32). When it is determined that the voice data acquired by the voice acquisition device 5g does not match the alert information notified to the worker (step S32; NO), the notification emphasizing device 5k notifies the alert information notified for a certain time or more. Is emphasized and notified (step S41). Then, returning to step S31 described above, the attention recognizing device 5h again compares the voice data acquired by the voice acquisition device 5g with the attention calling information notified to the worker. When the worker's voice data matches the alert information, the alert notification release device 5i cancels the alert information that matches the voice data (steps S32 and S33).

  As described above, according to the maintenance work support device according to the fourth embodiment, the notification emphasizing device 5k emphasizes the notification of the alerting information when the notification of the alerting information by the alerting notification device 5e elapses for a certain period of time. Thereby, since it becomes easy for a worker to notice attention alerting information, recognition failure of alerting information at the time of inspection work can be reduced.

[Embodiment 5]
A configuration example of the maintenance work support apparatus according to the fifth embodiment will be described. FIG. 12 is a block diagram illustrating a configuration example of the maintenance work support apparatus according to the fifth embodiment. The fifth embodiment is different from the first embodiment in that the inspection contents are also notified to the worker.

  The elevator 1 includes an inspection content database 90 and an inspection database transmission device 100. The inspection content database 90 functions as a storage unit, and stores the reference image of the inspection mark N and the inspection content (inspection information) in association with each other. For example, the inspection content database 90 stores a third table (not shown) composed of items of the reference image of the inspection mark N, the inspection location, and the inspection location. Further, the inspection content database 90 stores a fourth table T4 including items of inspection location, inspection location, and inspection content. By referring to the third table, the inspection location and the inspection location are specified based on the reference image of the inspection mark N, and by referring to the fourth table T4, the inspection content is specified based on the inspection location and the inspection location. Is done.

  The inspection location is a location to be inspected at the inspection location, such as a control panel, a brake, a sheave, and a rope. The inspection content is content to be inspected at the inspection location, for example, voltage measurement of the power source, confirmation of presence or absence of oil adhesion on the brake drum, and the like.

  The inspection mark N is formed in a certain size, and includes a first element V of the outer frame and a second element W written in the frame of the first element V. The first element V indicates an inspection place, and the second element W indicates an inspection place. The second element W can be omitted. The first element V is described by a figure such as a quadrangle, a triangle, or a circle (circle). FIG. 12 shows an example in which the first element V is a quadrangle. The square first element V indicates that the inspection location is the machine room 3, the triangular first element V indicates that the inspection location is a pit, and the circular first element V indicates that the inspection location is a car. 10 is shown.

  The second element W is indicated by a symbol such as “A”, “B”, “C”, “D”. For example, the symbol “A” indicates that the inspection location is a control panel, and the symbol “B” indicates that the inspection location is a brake. As described above, the inspection mark N is described by a combination of the first element V indicating the inspection location and the second element W indicating the inspection location.

  The inspection database transmission device 100 is connected to the mobile terminal 5 by wireless such as wireless LAN or infrared communication, and transmits information in the inspection content database 90 to the mobile terminal 5. The information in the inspection content database 90 may be transmitted from the operation mode transmitting device 80. Further, the inspection content database 90 may be provided in the mobile terminal 5.

  The portable terminal 5 includes an inspection location detection device 5m. The inspection location detection device 5m functions as a determination unit and a control unit, and detects the inspection content in the inspection content database 90 that matches the inspection mark N. For example, the inspection location detection device 5m compares the photographed image of the inspection mark N with the reference image of the inspection mark N in the third table stored in the inspection content database 90, and determines whether or not they match. When it is determined that the photographed image of the inspection mark N matches the reference image of the inspection mark N, the inspection point detection device 5m detects the inspection place and inspection point corresponding to the reference image of the inspection mark N. The inspection location detection device 5m detects the inspection content that matches the inspection location and the inspection location from the fourth table T4 of the inspection content database 90. The inspection location detection device 5m outputs the detected inspection content to the alerting notification device 5e.

  Next, an operation example of the maintenance work support apparatus according to the fifth embodiment will be described. FIG. 13 is a flowchart illustrating an operation example of the maintenance work support apparatus according to the fifth embodiment. First, the inspection database transmission device 100 transmits information in the inspection content database 90 to the inspection point detection device 5m of the portable terminal 5 (step S51). The inspection location detection device 5m compares the inspection mark N imaged by the imaging device 5b with the information in the inspection content database (step S52). The inspection location detection device 5m determines whether or not the inspection mark N matches the information in the inspection content database (step S53). When it is determined that the inspection mark N matches the information in the inspection content database (step S53; YES), the alerting notification device 5e notifies the worker of the inspection content corresponding to the inspection mark N (step S54). The worker confirms the inspection content notified by the alerting notification device 5e.

  Next, when the operation mode of the elevator control device 60 is the inspection operation mode, the operation mode transmission device 80 transmits the fact that it is the inspection operation mode to the worker's portable terminal 5 (steps S1 to S3). The portable terminal 5 confirms the caution mark M photographed by the photographing device 5b, and compares the confirmed caution mark M with information in the alert database 5a (steps S4 and S5). When the inspection location and the risk factor of the caution mark M match the inspection location and the risk factor in the alert database 5a (step S6; YES), the alert notification device 5e operates the alert information corresponding to the attention mark M. The employee is notified (step S7).

  As described above, according to the maintenance work support apparatus according to the fifth embodiment, the inspection contents corresponding to the inspection mark N attached to the inspection place and the inspection place are notified to the worker. Thereby, it can prevent that an operator leaks the inspection of an inspection location.

  Moreover, since the inspection mark N is comprised from the 1st element V which shows an inspection place, and the 2nd element W which shows an inspection place, the inspection mark N can be made into a simple structure. This facilitates comparison between the captured image of the inspection mark N and the reference image. Therefore, the accuracy of matching the inspection mark N can be improved and the processing time can be shortened.

[Modification]
Next, modified examples of the first to fifth embodiments will be described. Although the caution mark M has been described as being composed of the first element P of the outer frame and the second element Q of the symbol, the caution mark M is not limited to this. The attention mark M may be, for example, a combination of symbols as long as it can easily recognize the image. Further, the inspection mark N may be a combination of symbols as long as the image can be easily recognized.

  Further, the notification emphasizing device 5k may emphasize and notify the alert information based on the distance to the attention mark M measured by the mark distance measuring device 5f. For example, if the distance to the attention mark M is close, the degree of emphasis is increased.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
