Description

  The present invention relates to an elevator maintenance management system that supports the selection of maintenance personnel who restore a failure when an elevator or other elevator equipment failure occurs.

  When a failure occurs in the elevator equipment that is subject to maintenance in the building, the abnormality reporting device installed in the elevator equipment detects the failure and automatically reports the failure to the monitoring center of the maintenance company, or the building concerned The administrator (administrator) reports the failure to the monitoring center. Normally, when an operator of a monitoring center receives a report or notification of a failure, it checks the schedule of multiple maintenance personnel who include the building in the maintenance area, and is likely to be in the vicinity of the building, for example. Maintenance personnel who are not likely to be working now are selected, and the maintenance personnel are inquired as to whether or not the building can be dispatched. At that time, if there is a response from the inquired maintenance staff that it can be dispatched immediately, the maintenance staff can be instructed to dispatch to the building. In addition, if all the responses from the inquired maintenance personnel have the condition that they can be dispatched if the current maintenance work is interrupted, the monitoring center operator will consider the current status of each maintenance personnel. The maintenance staff who judged it to be the optimum was instructed to go to the building.

  However, as a countermeasure when dispatching maintenance personnel to the building where the failure occurred, the operator of the monitoring center checked the schedule of many maintenance personnel on the day and selected candidates to inquire about availability. However, since the selection of dispatch personnel could not be performed accurately and quickly, there was a risk that maintenance personnel suitable for recovery of the failure that occurred could not be dispatched to the building at an early stage.

  Therefore, conventionally, a technique is known in which the current position of each maintenance staff is specified by GPS (Global Positioning System) in order to find maintenance staff that can be dispatched to the building where the failure has occurred at an early stage (see, for example, Patent Document 1). . According to such conventional technology, since the maintenance staff in the vicinity of the building where the failure has occurred is immediately identified, a maintenance staff suitable for the recovery of the failure that occurred can be selected from a plurality of maintenance staff who can arrive at the building early. It becomes easy to select.

JP 2004-110117 A

  By the way, even if you select several maintenance personnel who can arrive at the building where the failure occurred in the elevator equipment (failure building) and can cope with the recovery of the failure, If a maintenance check is being performed in another building, it is not possible to immediately rush to the building where the failure occurred from that building. In other words, each maintenance staff must leave the elevator in the original state that can be used by the user after suspending the ongoing work, and can not leave for the building where the failure occurred. It depends on the content and progress of the work. Therefore, simply specifying the current position of the maintenance staff with GPS as in the above-described prior art cannot predict the arrival time when the maintenance staff is dispatched to the malfunctioning building. It was not possible to accurately select maintenance personnel who can arrive at the station. In addition, the selection criteria for selecting maintenance personnel suitable for the recovery of a failure that has occurred is not clear, so the selection of personnel considering recovery skills is not always accurate. For example, maintenance dispatched to the building where the failure occurred There were cases where recovery was not possible at the technical level of employees.

  The present invention has been made in view of such a situation of the prior art, and elevator maintenance capable of accurately and promptly selecting maintenance personnel who can reach a building where a failure has occurred in the elevator equipment at an early stage and can cope with restoration. The purpose is to provide a management system.

  In order to achieve the above object, the present invention provides an elevator maintenance management system that supports the selection of maintenance personnel that can be dispatched to a building in which an elevator equipment where a failure has occurred and that can repair the failure. Stores the failure recovery skill determination unit that determines the recovery skill for the content of the failure for each maintenance personnel selected based on the maintenance personnel database that stores the failure recovery skill information of each worker, and the work schedule of each maintenance personnel Work status that determines whether the maintenance personnel to be selected are currently working or moving based on the work schedule database that is being selected, and also determines the progress of the work if it is determined that work is in progress Time data by work situation that stores the time required for post-processing when the work is interrupted for each work content in correspondence with the progress of the work. Based on the base, the maintenance staff determined to be working by the work status determination unit calculates how much time is required to complete post-processing when the current work is interrupted Based on the work schedule database, the current position of the operation interruption addition time calculation unit and the maintenance staff to be selected is estimated, and the current position is departed for each maintenance staff based on the distance between the current position and the building. Based on the travel time calculation unit for calculating the travel time expected to reach the building, the calculation result of the work interruption additional time calculation unit, and the calculation result of the travel time calculation unit, The data output from each of the arrival time calculation unit for calculating the time at which each maintenance staff can arrive at the building, the failure recovery skill determination unit, the work situation determination unit, and the arrival time calculation unit is collected. And it was treated to a structure and a corresponding prediction list creating unit for displaying a predetermined fault correspondence list which is a processing result to a display device.

  As described above, in the elevator maintenance management system including the failure recovery skill determination unit, the work situation determination unit, the work interruption addition time calculation unit, the travel time calculation unit, the arrival time calculation unit, and the correspondence prediction list creation unit, Since the maintenance personnel selection suitable for recovery can be selected by the failure recovery skill determination unit based on the maintenance personnel database, accurate and quick selection of personnel in consideration of recovery skills is possible. In addition, it is possible to determine whether the maintenance staff to be selected is currently working or moving based on the work schedule database based on the work schedule database, and these maintenance staff leave the current position and arrive at the failure building. Since the travel time expected to be required can be estimated from the calculation result of the travel time calculation unit, it is possible to preferentially inquire the maintenance staff moving around the building whether it is possible to move out. In addition, even if the maintenance engineer to be selected is currently working, the time required for post-processing is added when the work is interrupted based on the progress status data determined by the work status determination unit. It can be calculated by the time calculation unit. Based on this calculation result and the calculation result of the travel time calculation unit, the arrival time when the maintenance worker currently working is dispatched to the failure building can be calculated by the arrival time calculation unit. It is possible to select a person who can arrive at the malfunctioning building at an early stage accurately and quickly. In addition, since the response prediction list creation unit instructs the display device to create a predetermined failure response list based on the data output from the failure recovery skill determination unit, work status determination unit, arrival time calculation unit, etc., monitoring is performed. The center operator can easily grasp the priority order of maintenance personnel suitable as dispatched personnel to the building where the failure has occurred by looking at the failure handling list, and can efficiently inquire about the availability of dispatch.

  In the elevator maintenance management system described above, the maintenance technician database includes failure recovery skill information for each failure point of the elevator equipment, including the level of failure and the level of restoration technology for each maintenance worker set according to the degree of restoration. It is preferable that the failure recovery skill determination unit determines whether or not the maintenance personnel to be selected can cope with the recovery of the failure that has occurred based on the data of the recovery technology level. This makes it possible to accurately determine the restoration skill of each maintenance staff in accordance with the location where the failure has occurred and the degree of the failure, so that it is possible to more appropriately select a maintenance staff suitable as a dispatched person to the building where the failure has occurred. In addition, if the failure that occurred is severe and maintenance personnel who can fully recover cannot be secured at an early stage, it will be urgent to dispatch maintenance personnel who can handle temporary recovery to the failure building for the time being. If the restoration technology level data of each maintenance personnel corresponding to the degree of the failure is stored in the failure restoration skill information, it is convenient to flexibly cope with the failure of the elevator equipment under various circumstances.

  In addition, as described above, in the case where the failure recovery skill determination unit determines the maintenance personnel that can cope with the recovery of the failure that has occurred and the maintenance personnel that cannot respond, the work status determination unit, the travel time calculation unit, and the arrival time calculation unit If maintenance personnel to be selected are limited to those who are determined to be able to cope with failure recovery by the failure recovery skill determination unit, and maintenance personnel who cannot cope with recovery are not displayed in the failure response list, The operator of the monitoring center can more quickly select a suitable maintenance person as a dispatched person to the failure building.

  According to the elevator maintenance management system of the present invention, the maintenance personnel selection suitable for the recovery of the failure that has occurred can be selected by the failure recovery skill determination unit based on the maintenance personnel database, so that accurate and quick selection of personnel considering the recovery skills is possible. It becomes. In addition, it is possible to determine whether the maintenance staff to be selected is currently working or moving based on the work schedule database based on the work schedule database, and these maintenance staff leave the current position and arrive at the failure building. Since the travel time estimated by the travel time calculation unit can be estimated by the travel time calculation unit, it is possible to preferentially inquire of the maintenance personnel who are moving in the vicinity of the building. In addition, even if the maintenance personnel to be selected are currently working, the time required for post-processing is added when the work is interrupted based on the progress degree data calculated by the work status determination unit. It can be calculated by the time calculation unit. Therefore, it is possible to accurately and quickly select a person who can arrive at the failure building early among all the maintenance personnel to be selected. In addition, since the response prediction list creation unit instructs the display device to create a predetermined failure response list, the operator of the monitoring center looks at the failure response list, and the priority order of maintenance personnel suitable as dispatch personnel to the building where the failure has occurred is given. It can be easily grasped and it can be inquired whether or not it is possible to dispatch efficiently. Therefore, it is possible to provide an elevator maintenance management system in which maintenance personnel who can arrive at a building where a failure has occurred in the elevator equipment and can cope with recovery can be selected accurately and quickly.

  Embodiments of the present invention will be described below with reference to the drawings. First, an overall configuration of an elevator maintenance management system according to the present embodiment will be described with reference to FIG.

  The management building 1 is provided with an elevator 11 that is a maintenance / monitoring target of a maintenance company, a control panel 12 that controls the operation thereof, and an abnormality notification device 13 connected to the control panel 12. The maintenance company performs maintenance and monitoring of elevators installed in a plurality of buildings including the management building 1, and these elevators are monitored remotely by the monitoring center 3. That is, each building including the management building 1 exists in a place geographically separated from the monitoring center 3. In the management building 1, the abnormality notification device 13 constantly monitors the elevator 11, and when any abnormality occurs in the elevator 11, the abnormality notification device 13 automatically reports the abnormality occurrence to the monitoring center 3 via the communication means 2. To do. At that time, the abnormality reporting device 13 not only reports that an abnormality has occurred in the elevator 11 of the management building 1, but also reports the content of the abnormality. As the communication means 2, a public telephone line or the Internet is used.

  The following description will be given on the assumption that a failure has occurred in the elevator 11 in the management building 1 which is any one of a plurality of buildings whose elevators are maintained and monitored by the maintenance company.

  When the monitoring center 3 receives a report on the occurrence of an abnormality in the elevator 11 from the management building 1, the operator 34 can recover the failure that has occurred from a plurality of maintenance personnel including the management building 1 in the maintenance area. In addition, maintenance personnel 4 who can arrive at the management building 1 as soon as possible are selected. Although selection criteria will be described later, the maintenance personnel 4 can be easily selected. Then, the operator 34 makes an inquiry to the maintenance staff 4 suitable as a dispatched person to the management building 1 through the communication means 2, and dispatches the maintenance staff who can be dispatched to the management building 1. Instruct.

  The maintenance staff 4 visits a plurality of buildings and carries out maintenance work in accordance with a work schedule planned in advance. The maintenance staff 4 also has a portable communication device 41 such as a mobile phone having a data transmission function, and the time when the user enters the building where the work is performed or the time when the worker completes the work and leaves the building. In each case, registration is made from the portable communication device 41 to the work performance database 36 of the maintenance management device 31 via the communication means 2. In addition, when an abnormality occurs in each building including the management building 1, the operator 34 makes an inquiry about whether or not to dispatch and an instruction to dispatch through the communication means 2 and the portable communication device 41. In the following description, “database” is abbreviated as “DB”, and therefore, “work record DB” means “work record database”, for example.

  The maintenance management device 31 is a computer that implements a maintenance management function in this embodiment. The maintenance management device 31 includes a failure recovery skill determination unit 31a, a work situation determination unit 31b, a work interruption addition time calculation unit 31c, a travel time calculation unit 31d, an arrival time calculation unit 31e, and a corresponding prediction list creation unit 31f. These are mainly realized by a computer processing unit. Further, the failure handling list 35a (see FIG. 6), which is the processing result of the handling prediction list creation unit 31f, is displayed on the display device 35 (including the print format). That is, when a display device such as a liquid crystal display device or a CRT is used as the display device 35, a failure handling list 35a is displayed on the display screen, and when a printer is used as the display device 35, a predetermined value is displayed. The failure handling list 35a is printed on this sheet.

  The failure recovery skill determination unit 31a is selected on the basis of the maintenance worker DB 37 storing the failure recovery technical level of each maintenance staff when the abnormality notification of the elevator 11 is transmitted from the abnormality notification device 13 of the management building 1. For each target maintenance engineer, determine the recovery skill for the contents of the failure that occurred. Here, the maintenance personnel to be selected mean all maintenance personnel 4 whose management building 1 is included in the maintenance area.

  The work status determination unit 31b determines whether the maintenance staff to be selected is currently working or moving based on the work schedule DB 38 that stores the work schedule of each maintenance staff. If it is determined, what kind of work is being performed in which building and the degree of progress of the work is determined.

  The work interruption additional time calculation unit 31c is based on the work situation time DB 39 that stores the time required for post-processing when the work is interrupted for each work content in correspondence with the progress of the work. For maintenance personnel determined to be working by the work status determination unit 31b, the time required to complete post-processing when the current work is interrupted is calculated. In other words, the maintenance staff who are working cannot return to the management building 1 at the site of the failure, and it is necessary to restore the original state until the elevator is returned to the original state that the user can use after the work is interrupted. Since the time varies depending on the content and progress of the work, the maintenance staff working in another building by comparing the progress of the work determined by the work situation determination unit 31b with the data in the work situation time DB 39 Calculates the time that is expected to be required to stop the work and leave the building.

  Based on the distance between the current position of the maintenance staff to be selected and the management building 1 at the site of the failure, the travel time calculation unit 31d leaves the current position and arrives at the management building 1 for each maintenance staff. Calculate the estimated travel time. At that time, the travel time calculation unit 31d calculates the current position of each maintenance staff based on the work schedule DB 38, the work performance DB 36, the geographical information of each building, and the like.

  It is assumed that the arrival time calculation unit 31e is dispatched to the management building 1 at the failure occurrence site for each maintenance staff to be selected based on the calculation result of the work interruption additional time calculation unit 31c and the calculation result of the travel time calculation unit 31d. In this case, the arrival time is calculated. That is, in the case of a maintenance worker who is moving, the arrival time can be predicted by adding the movement time calculated by the movement time calculation unit 31d to the current time, and in the case of a maintenance worker who is working, the work interruption additional time calculation unit 31c. The arrival time can be predicted by adding the time required for the post-processing calculated in step 1 and the movement time calculated by the movement time calculation unit 31d to the current time.

  Note that the maintenance personnel to be selected in the work situation determination unit 31b, the travel time calculation unit 31d, and the arrival time calculation unit 31e may be the same as the maintenance personnel to be selected in the failure recovery skill determination unit 31a. The maintenance personnel targeted by the determination unit 31b, the travel time calculation unit 31d, and the arrival time calculation unit 31e are limited to the maintenance personnel determined by the failure recovery skill determination unit 31a to be able to cope with the recovery of the failure that has occurred in the elevator 11. You may keep it.

  The correspondence prediction list creation unit 31f acquires and processes the data output from the failure recovery skill determination unit 31a, the work situation determination unit 31b, and the arrival time calculation unit 31e, and processes a predetermined failure correspondence list 35a. Is displayed on the display device 35. In the failure handling list 35a, for example, as shown in FIG. 6, a list of maintenance personnel is displayed in order of the arrival time of arrival at the management building 1 at the failure occurrence site in ascending order.

  The display device 35 is installed so that the operator 34 can easily visually recognize the display screen (in the case of a display device) or printed paper (in the case of a printer). By looking at the failure handling list 35a displayed by the display device 35, the operator 34 can easily compare the predicted arrival times and recovery skills of maintenance personnel who can arrive at the management building 1 at the failure occurrence site early. Can do. Therefore, the operator 34 can accurately and quickly select a maintenance staff particularly suitable as a dispatched person to the management building 1.

  Next, the operation procedure of the elevator maintenance management system according to this embodiment will be described with reference to the flowchart of FIG.

  When a failure occurs in the elevator 11 of the management building 1 (step S1), the abnormality reporting device 13 that has detected the abnormality identifies the occurrence of the abnormality, its contents, and the building to the abnormality reporting processing device 32 of the monitoring center 3. (For example, an identification code) is reported (step S2). The abnormality report processing device 32 refers to the management building DB 30 in which information related to a plurality of management buildings is stored in association with IDs, so that information such as the name and address of the management building 1 that is the reporting source is obtained from the reported ID. In addition, the content of the failure (how much failure has occurred at which part of the elevator, etc.) is specified from the notified abnormality content (step S3). For example, if the degree of failure is classified as “minor”, “medium”, or “severe”, the failure location is “car door electrical system” and the failure level is “medium”. Can be identified. Information regarding the management building 1 and information regarding the failure content are sent from the abnormality notification processing device 32 to the maintenance management device 31. Note that a storage device such as a semiconductor memory or a magnetic disk can be applied as the management building DB 30 and other DBs. Even if there is no automatic notification from the abnormality notification device 13, the administrator (administrator) 14 of the management building 1 may notify the operator 34 of the monitoring center 3 that the elevator 11 has failed. The response to the case will be described later.

  After the step S3 in the flowchart of FIG. 2, in the maintenance management device 31, the failure recovery skill determination unit 31a first refers to the failure recovery skill information for each maintenance person as shown in FIG. Thus, the recovery skill of each maintenance staff is determined for the content of the failure (failure location and failure level) specified by the abnormality reporting device 13 of the management building 1 (step S4). At this time, the maintenance personnel who are targets for determining the recovery skill are all maintenance personnel whose management building 1 is included in the maintenance area as described above. The failure recovery skill information shown in FIG. 3A is stored in the maintenance worker DB 37 as data in which the level of the recovery skill for each failure point is quantified for each maintenance worker A, B,. ing. As for the level of these recovery skills, as shown in the skill level table shown in Fig. 3 (b), the maintenance staff responds according to the degree of failure (minor, moderate, severe) and the degree of recovery (temporary recovery, complete recovery). It is set with the presence or absence of ability ranked as level 1, level 2, .... This skill level table is also stored in the maintenance staff DB 37.

  For example, when it is identified by the abnormality reporting device 13 that a moderate failure has occurred in the electrical system of the car door, when the repair skills for this failure are compared for the two maintenance personnel A and B, the maintenance personnel A becomes level 5 However, since it is determined that the maintenance staff B is level 2, it is found that the temporary maintenance cannot be handled.

  After the step S4 in the flowchart of FIG. 2, the work status determination unit 31b determines whether the maintenance staff to be selected is currently working or moving by referring to the work performance DB 36 and the work schedule DB 38. (Step S5). In the work schedule DB 38, for each maintenance staff, the work target building ID, the scheduled entry time and the scheduled exit time (may be the scheduled work start time and scheduled work end time), the work content, etc. Stores data related to schedules. Further, the maintenance staff operates the mobile communication device 41 to register the actual entrance time and exit time in the work performance DB 36 of the monitoring center 3 as needed via the communication means 2. As a result, even when the maintenance staff cannot act according to the work schedule due to, for example, work delay, the current position of the maintenance staff can be estimated from the data of the work performance DB 36 and the work schedule DB 38.

  When it is determined in step S5 of the flowchart of FIG. 2 that the maintenance staff is working by the work status determination unit 31b, the work status determination unit 31b determines the progress of the work (step S6). For example, as shown in FIG. 4, a schedule for performing a “car door inspection work” in a predetermined building from 10:00 am to 11:00 am as a work schedule of a maintenance staff is registered in the work schedule DB 38 and as scheduled. In the case where it can be confirmed in the work result DB 36 that the work has been started, and the monitoring center 3 receives an abnormality report from the management building 1 at 10:24, the work status determination unit 31b determines the scheduled work time (60 In this case, the work progress is determined to be 40%. The percentage of the work time (24 minutes) up to the time of the failure occurrence is calculated as the work progress.

  If it is determined in step S5 that the maintenance staff is working and the progress of the work is determined in step S6, the maintenance staff interrupts the work and performs post-processing in the work interruption additional time calculation unit 31c. It calculates how much time is required to complete (step S7). For example, when suspending the inspection of a car door, the operating state of the elevator switched for inspection must be returned from the maintenance mode to the normal mode, and if the maintenance staff is working on the car, escape from there There must be. In addition, if a sticker that informs the customer that the elevator is under inspection is posted on each floor, these stickers must also be collected. When the work is interrupted in this way, it is necessary to allow time required for the restoration of the original state. However, depending on the work content and the degree of progress, additional time required for the processing after the interruption (referred to as “additional time” for convenience) Since the additional time is stored in the work situation time DB 39 in advance and the data is referred to, the work interruption additional time calculation unit 31c is expected to add after the interruption of each maintenance worker during the work. Calculate time.

  That is, as shown in FIG. 5, the work situation time DB 39 stores data in which required time (additional time) after interruption is predicted according to the degree of progress for each work content. For example, as described above, when the car door inspection is interrupted with a progress of 40%, it is necessary to allow 15 minutes for the post-processing, and when the brake inspection is interrupted with a progress of 50%. Must allow 40 minutes for post-processing. The work interruption additional time calculation unit 31c compares the work contents of the maintenance staff read from the work schedule DB 38 and the work progress determined by the work situation determination unit 31b with the data in the work situation time DB 39, Estimate additional time after work interruption.

  However, the additional time data stored in the work situation time DB 39 is a value at a standard work site, and the actual additional time after the work interruption depends on the type of elevator, the number of floors of the building, and the like. It becomes a thing. Therefore, a coefficient corresponding to the work target building may be determined in advance, and the coefficient data may be corrected by multiplying the standard value read from the work situation time DB 39 by the work interruption addition time calculation unit 31c. When performing such correction, the work interruption additional time calculation unit 31c refers to the management building DB 30 based on the data of the work target building read from the work schedule DB 38, thereby determining the number of floors of the work target building and the elevators. Since the model can be specified, the coefficient data of this work target building can be acquired. Therefore, as described above, by adding the standard additional time read from the work situation time DB 39 based on the work contents and work progress of the maintenance staff and the coefficient data of the work target building, the model of the elevator In addition, it is possible to cause the work interruption additional time calculation unit 31c to calculate the additional time after the work interruption corrected in consideration of the number of floors of the building. In addition, as the coefficient data of the work target building, a coefficient corresponding to the combination of the model and the number of floors may be set, or a coefficient may be set for each model and the number of floors.

  In step S5 of the flowchart of FIG. 2, after it is determined that the maintenance staff is moving, or after it is determined that the maintenance staff is working and the processing in steps S6 and S7 is completed, in the movement time calculation unit 31d, The travel time of each maintenance staff is estimated by calculating the distance between the current position of each maintenance staff read from the work performance DB 36 and the work schedule DB 38 and the management building 1 at the failure occurrence site (step S8). For example, the current position of the maintenance worker who is working can be identified by comparing the data of the work target building read from the work schedule DB 38 with the data of the management building DB 30. Further, since the location of the management building 1 at the failure occurrence site is known, the distance between the management building 1 and the current position of each maintenance staff can also be calculated. The travel time calculation unit 31d divides the distance to the failure occurrence site (management building 1) calculated in this way by a predetermined movement speed, or the unit travel time determined as a minute per unit distance to the failure occurrence site. By calculating the distance, the time required for movement is calculated for each maintenance worker.

  The work schedule DB 38 stores the moving means (automobile, motorcycle, bicycle, walking, etc.) of each maintenance worker and a predetermined moving speed (or unit moving time) set according to the moving means. It is more preferable if the travel time calculation unit 31d calculates the travel time of each maintenance staff by referring to the data.

  When the travel time calculation unit 31d specifies the current position of the maintenance worker determined to be moving, the work performance DB 36 and the work schedule DB 38 are referred to, and the work target building that the maintenance worker is currently heading After identifying the work target buildings that have been working until immediately before and acquiring the location information of these two buildings, for example, the intermediate point between these two buildings is regarded as the current position of the maintenance staff. Alternatively, with reference to the work performance DB 36 and the work schedule DB 38, the maintenance staff performs the correction considering the time difference between the exit time and the scheduled exit time of the work target building that the worker has been working on until immediately before. The current position of the maintenance staff may be specified with high accuracy based on the progress of movement at the time.

  When the travel time of each maintenance person is estimated in step S8 of the flowchart of FIG. 2, the arrival time calculation unit 31e calculates the time at which the maintenance person can arrive at the management building 1 at the failure occurrence site for each maintenance person (step S9). That is, in the case of a maintenance worker who is determined to be currently working by the work status determination unit 31b, the calculation result (addition time) of the work interruption additional time calculation unit 31c and the calculation result (movement time) of the movement time calculation unit 31d are currently The arrival time can be predicted by adding to the time. Further, in the case of a maintenance worker who is determined to be currently moving by the work status determination unit 31b, the arrival time can be predicted by adding the calculation result (movement time) of the movement time calculation unit 31d to the current time.

  In addition, since the abnormality notification processing device 32 of the monitoring center 3 specifies the division area to which the management building 1 at the failure occurrence site belongs based on the management building DB 30, this maintenance building 1 is included in the maintenance staff area of each maintenance staff. It can be specified whether or not. Then, if all the maintenance staff whose management building 1 at the site where the failure occurs is included in the maintenance area, the processes in steps S4 to S9 are performed, it is easy for the maintenance staff to arrive at the management building 1 quickly. Become. However, the failure handling list displayed on the display device 35 by performing the processing in steps S5 to S9 for only the skill level that can be at least temporarily recovered for the failure that has occurred and the maintenance personnel determined in step S4. 35a may be set so that maintenance personnel who cannot cope with the recovery are not displayed.

  When the predicted arrival time (time at which arrival is possible) of each maintenance staff at the failure occurrence site is calculated in step S9 of the flowchart of FIG. 2, the maintenance prediction list creating unit 31f, for example, as shown in FIG. Are grouped in order to display them in the failure handling list 35a in order of their arrival arrival times (step S10). In other words, the correspondence prediction is performed so that a group whose predicted arrival time is within 10 minutes from the current time is displayed at the beginning of the failure handling list 35a, and a group within 20 minutes, a group within 30 minutes,... The list creation unit 31f organizes data acquired from the arrival time calculation unit 31e and the like. Further, the correspondence prediction list creation unit 31f also acquires data from the failure recovery skill determination unit 31a and the work situation determination unit 31b, and determines whether the maintenance skill of each maintenance staff is currently working or moving. If it is medium, the data is arranged so that information such as the degree of progress can also be displayed in the failure handling list 35a.

  Thereafter, the correspondence prediction list creation unit 31f instructs the display device 35 to create a failure correspondence list 35a of a predetermined format, and the failure correspondence list 35a as shown in FIG. S11). In addition, since the maintenance staff who is moving is more convenient than the maintenance staff currently working as the dispatch staff to the failure occurrence site, the maintenance staff who is moving is included in the failure handling list 35a according to the command of the handling prediction list creation unit 31f. May be displayed with emphasis.

  If the failure handling list 35a is displayed on the display device 35 in step S11 of the flowchart of FIG. 2, the operator 34 of the monitoring center 3 refers to the failure handling list 35a and selects dispatch personnel to the failure occurrence site ( Step S12). At that time, if the maintenance conditions and recovery skills of the maintenance personnel to be selected are the same, the maintenance personnel who can arrive at the management building 1 at the site of failure are preferentially selected, but they are working in other buildings. If the maintenance staff of the company interrupts the work, it is easy for the users of the building to be adversely affected. Therefore, if the arrival time at the failure occurrence site is only slightly delayed, it is better to select the maintenance staff currently moving. In addition, if the user who uses the management building 1 is expected to be seriously damaged if the failure that has occurred is not fully recovered, the time at which the failure can be reached from the maintenance staff that can handle the complete recovery is earlier It is better to select the person with priority. As described above, various factors need to be taken into consideration when selecting the dispatched personnel to the site where the failure occurs, but the operator 34 can select an appropriate person by looking at the failure handling list 35a displayed on the display device 35. It can be done quickly.

  Thereafter, the operator 34 makes an inquiry to the selected maintenance staff as to whether or not it can be dispatched to the management building 1 at the failure occurrence site (step S13). Returning to step S12, another maintenance staff is inquired as to whether or not to dispatch. At that time, the operator 34 inquires whether or not dispatching is possible in order from maintenance personnel who are considered to have a high priority in consideration of various factors. Then, steps S12 to S13 are repeated until a dispatchable maintenance worker is found, and a dispatch to the management building 1 is instructed to a maintenance worker who has obtained a reply that dispatch is possible (step S14).

  As described above, according to the present embodiment example, maintenance personnel suitable for recovery of a failure that has occurred can be selected by the failure recovery skill determination unit 31a based on the maintenance worker DB 37. Person selection is possible. In addition, whether the maintenance personnel to be selected is currently working or moving can be determined by the work status determination unit 31b based on the work schedule DB 38, and these maintenance personnel leave the current position and have a failure occurrence site ( Since the travel time estimated to be required to reach the management building 1) can be estimated by the travel time calculation unit 31d, it is possible to preferentially inquire whether or not it is possible to move to the maintenance staff moving near the failure site. . Further, even if the maintenance staff to be selected is currently working, additional time expected for post-processing when the work is interrupted based on the data such as the degree of progress calculated by the work situation determination unit 31b. It can be calculated by the additional time calculation unit 31c. Therefore, it is possible to accurately and quickly select a person who can arrive at the failure occurrence site at an early stage from all the maintenance personnel to be selected. Further, since the response prediction list creation unit 31f instructs the display device 35 to create a predetermined failure response list 35a, the operator 34 of the monitoring center 3 can be suitable as a dispatched person to the failure occurrence site by looking at the failure response list 35a. The priority order of maintenance personnel can be easily grasped, and it can be efficiently inquired about whether or not dispatch is possible.

  Further, in this embodiment, the maintenance technician DB 37 stores, as failure recovery skill information, data on the level of recovery technology of each maintenance worker set according to the failure level and the recovery level for each failure location of the elevator. The failure recovery skill determination unit 31a determines whether or not the maintenance staff to be selected can cope with the recovery of the generated failure based on the data of the recovery technology level. The restoration skill of each maintenance staff can be accurately determined according to the location and the degree of failure. In addition, if a maintenance engineer who can recover completely due to a severe failure cannot be secured at an early stage, it is urgent to dispatch a maintenance engineer who can handle temporary recovery to the failure site. As in the embodiment example, if the restoration technology level data of each maintenance staff corresponding to the degree of restoration is stored in the failure restoration skill information, it is possible to flexibly deal with elevator failures under various circumstances. Convenient.

  In the present embodiment, the travel time calculation unit 31d calculates the current position of the maintenance personnel to be selected based on the data in the work schedule DB 38 and the work performance DB 36. Sometimes, it is not necessary for the operator 34 of the monitoring center 3 to input the current position data of each maintenance person specified by GPS or the like, and the selection work is not complicated.

  Further, as described above, the maintenance personnel to be selected in the work situation determination unit 31b, the travel time calculation unit 31d, and the arrival time calculation unit 31e can cope with the recovery of the failure by the failure recovery skill determination unit 31a (at least temporarily recovery). If the maintenance staff is determined to be capable of skill level) and the maintenance staff that cannot handle the recovery is not displayed in the failure handling list 35a, the operator 34 of the monitoring center 3 This makes it possible to more quickly select a suitable maintenance worker as a dispatched worker.

  In the above embodiment, the case where the abnormality reporting device 13 automatically reports the occurrence of a failure of the elevator 11 to the monitoring center 3 has been described. However, the administrator 14 who performs the management work of the management building 1 or the like May be reported to the operator 34 of the monitoring center 3. In this case, the operator 34 asks the administrator 14 for information such as the name and address of the management building 1 that is the site of the failure, the content of the failure, and inputs the necessary information to the input device 33. Since the information input to the input device 33 is sent to the maintenance management device 31, the failure handling list 35a is displayed on the display device 35 by being processed in the same procedure as in the above embodiment.

  In the above-described embodiment, the elevator that recovers from the failure is described as an elevator. However, the present invention can be applied even if the elevator that recovers from a failure is an escalator. In that case, it is preferable to set the coefficient used for calculating the additional time expected after the work is interrupted in another building based on the escalator model, the number of installed units, and the like.
