Description

  The present invention relates to an elevator maintenance management system that dispatches maintenance personnel when an elevator abnormality occurs.

  Normally, when an abnormality occurs in an elevator, information on the occurrence of the abnormality is issued to the monitoring center from a control device installed in the elevator. When the operator of the monitoring center receives information on the occurrence of an abnormality from the elevator, the operator of the monitoring center dispatches maintenance personnel to the site to check the situation on the monitor screen.

Here, as a method of dispatching maintenance personnel when an abnormality occurs, for example, the location of maintenance personnel existing in each region is specified by GPS (global positioning system), and maintenance personnel close to the site are dispatched preferentially. It is known (see, for example, Patent Document 1).
JP 2004-110117 A

  However, each maintenance staff usually goes to the site where an abnormality occurs in response to a request for dispatch at a branch office or another site. Also, if it is a holiday, etc., it may go to the site in response to a request for dispatch at home. In such a case, since the means for moving to the site varies depending on the maintenance staff, the arrival time greatly depends on the traffic situation at that time. For example, a maintenance person who can move by car on weekdays can often move only on foot during a holiday that is not scheduled for maintenance.

  The present invention has been made in view of the above points, and in the event of an abnormality, an elevator that can efficiently perform maintenance work by dispatching maintenance personnel in consideration of traffic conditions to the site. The purpose is to provide a maintenance management system.

  The elevator maintenance management system according to the present invention includes a movement detecting means for detecting a moving means for each maintenance person to go to the site when an abnormality occurs in the monitored elevator, and the movement detecting means detects the moving means. In consideration of the traffic situation obtained by the traffic situation acquisition means for obtaining at least the traffic situation of the road and the railway from an external information transmission source, It is characterized by comprising arrival predicting means for predicting the time until arrival, and dispatch processing means for preferentially dispatching maintenance personnel with an early arrival time predicted by the arrival predicting means to the site.

  According to the present invention, when an abnormality occurs, a restoration work can be performed by efficiently dispatching maintenance personnel in consideration of the traffic situation to the site.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a configuration of an elevator maintenance management system according to an embodiment of the present invention. 10 in the figure is a property (building), and an elevator 11 to be monitored is installed.

  The elevator 11 is provided with a hoisting machine 12, a car 14 that moves up and down via a rope 13 wound around the hoisting machine 12, a counterweight 15, and the like. The control device 16 controls the operation of the elevator 11 and is composed of a computer equipped with a CPU, ROM, RAM, and the like.

  The control device 16 is connected to the monitoring center 18 via the communication network 17. As the communication network 17, a telephone line, the Internet, or the like is used, but the communication form is not particularly limited.

  The monitoring center 18 remotely monitors the operation state of the elevator 11 via the communication network 17. In the example of FIG. 1, only one elevator 11 is illustrated, but actually, various elevators installed in each building are connected to the monitoring center 18 via the communication network 17. The monitoring center 18 constantly monitors the operating state of these elevators, and if an abnormality occurs, a maintenance staff 19 is dispatched to the site.

  The maintenance staff 19 possesses a communication terminal device 20 such as a mobile phone. The terminal device 20 is provided with a GPS reception function. By transmitting GPS information received by the GPS reception function to the monitoring center 18, the monitoring center 18 can identify the current position of the maintenance staff 19. It has become.

  The monitoring center 18 is connected to branch offices 21a, 21b, 21c,... Via a communication network 22 such as a public line or a dedicated line. In the branch stores 21a, 21b, 21c,..., Periodic maintenance inspections are performed on properties in each area.

  The monitoring center 18 is connected to an external information transmission source 23 that transmits at least traffic conditions relating to roads and railways. The information transmission source 23 is, for example, a site on the Internet or a transportation facility.

  FIG. 2 is a block diagram showing a device configuration of the monitoring center 18.

  The monitoring center 18 is provided with a communication device 31, a maintenance management device 32, an input device 33, a display device 34, and various databases 35 to 37.

  The communication device 31 performs communication processing with the control device 16 of the elevator 11 and with the terminal device 20 of the maintenance staff 19, and further communication processing with each branch store 21a, 21b, 21c. The maintenance management device 32 is a computer for realizing a maintenance management function, and includes a list creation unit 32a, a movement detection unit 32b, a traffic condition acquisition unit 32c, an arrival prediction unit 32d, and a dispatch processing unit 32e.

  When receiving abnormality information from the elevator 11 to be monitored, the list creation unit 32a estimates the failure status of the elevator 11, and creates a list of maintenance personnel suitable for the failure status based on a predetermined condition. The movement detection unit 32b detects a moving means for each maintenance person to go to the site. The moving means is, for example, an automobile, a motorcycle, a train, a bicycle, or a walk. The traffic condition acquisition unit 32c acquires at least the road and railway traffic conditions from the external information transmission source 23 for the moving means detected by the movement detection unit 32b. The arrival predicting unit 32d predicts the time until each maintenance staff arrives at the site in consideration of the traffic situation obtained by the traffic situation obtaining unit 32c. The dispatch processing unit 32e dispatches maintenance personnel with a quick arrival time predicted by the arrival prediction unit 32d to the site with priority.

  The input device 33 is used by an operator of the monitoring center 18 for inputting data and giving instructions. The display device 34 is used as a monitoring screen such as displaying a list of operation states of each property.

The property database (property DB) 35 stores information on properties.
Specifically, as shown in FIG. 3, the location of each property, the specifications and number of elevators, repair history (history of places repaired in the past), and past disaster situations (situations caused by disasters such as earthquakes) ), Priority (the order in which maintenance is inspected), and information such as the branch office in charge.

The failure database (failure DB) 36 stores information related to failures.
Specifically, as shown in FIG. 4, the failure status and the skill level data required for it, the relationship between the magnitude of shaking and the malfunctioning equipment (data such as how much shaking causes which equipment will fail) , Relationship data between abnormal data and failure part (data such as parts that are likely to fail depending on the content of the abnormality), relation data between failure and the number of people required to deal with it, repair tools required for each failure, etc. The information is memorized.

The maintenance staff database (maintenance staff DB) 37 stores information on maintenance staff.
Specifically, as shown in FIG. 5, information such as maintenance staff skills, moving means, maintenance schedule of the day, repair tools carried, and branch offices to which the user belongs is stored.

  Also, each branch store 21a, 21b, 21c... Is provided with the same device as the monitoring center 18.

  FIG. 6 shows the configuration of the branch store 21a as a representative.

  The branch store 21a is provided with a communication device 41, a maintenance management device 42, an input device 43, a display device 44, and various databases (DB) 45 to 47. The functions of these devices are basically the same as those of the monitoring center 18.

  However, out of various databases (DB) 45 to 47 provided in the branch store 21a, the property DB 45 stores only information related to properties in the area under the jurisdiction of the branch store 21a, and the maintenance staff DB 47 stores information in the branch store 21a. Only information about the maintenance personnel to which they belong is stored. Information in the property DB 45 and the maintenance staff DB 47 is sent to the monitoring center 18 and managed together with information on other branch stores.

  A monitoring center history unit 48 is provided in the branch store 21a. In the monitoring center history unit 48, the exchange with the monitoring center 18 remains as a history.

  Next, the operation of the embodiment will be described.

  FIG. 7 is a flowchart showing the processing operation of the monitoring center 18. Note that the processing shown in this flowchart is executed by the maintenance management device 32, which is a computer installed in the monitoring center 18, reading a predetermined program.

  When any abnormality occurs in the elevator 11 to be monitored, the control device 16 of the elevator 11 issues a notification to the monitoring center 18 via the communication network 17. Note that if the control device 16 of the elevator 11 does not have an abnormal alarm function, the building manager may notify the monitoring center 18.

  When the abnormality information is received from the elevator 11 (step S11), the maintenance management device 32 in the monitoring center 18 first estimates the failure state of the elevator 11 with reference to the failure DB 36, and selects maintenance personnel suitable for the failure state. List up based on predetermined conditions (step S12). The predetermined conditions include skills necessary for restoration, repair tools, jurisdiction areas, and the like.

If the skill required for recovery is a condition, the following processing is performed.
That is, first, referring to “relation data between abnormality data and failure part” in the failure DB 36 shown in FIG. Subsequently, referring to “failure situation and skill level data necessary for it”, the skill required to repair the part is determined.

  For example, it is assumed that there is an abnormal opening / closing of the car door of the elevator 11 and there is a notification to that effect. In such a case, for example, a part (equipment) such as a “door panel guide rail”, a “door opening / closing switch”, or a “holder engagement mechanism” is specified as a failure part related to the car door opening / closing abnormality.

  In addition, when estimating the failure situation, it may be possible to examine a part that is likely to break down depending on the property in consideration of “repair history”, “past disaster situation”, etc. of the property DB 35 shown in FIG.

  Subsequently, the skill required to repair such a faulty part is determined. Here, assuming that the skill of the maintenance staff is divided into the following five levels, in the above example, it is determined that at least level 3 or more is necessary.

  In addition, the level of the maintenance staff is appropriately updated by, for example, a level test periodically performed at each branch office.

Level 1: Equipment can be inspected Level 2: Equipment can be adjusted Level 3: Equipment can be easily repaired Level 4: Equipment can be repaired, including parts replacement Level 5: Whatever model you choose It can be handled by equipment.

  When the skills necessary for recovery are determined, maintenance personnel having the above-mentioned skills are searched from the maintenance personnel DB 37 shown in FIG. 5 as dispatch targets, and a list thereof is created. FIG. 8 shows an example of the dispatch target list. In this example, maintenance personnel having skills of level 3 or higher are dispatched.

  When the dispatch target list is created in this way, the maintenance management device 32 refers to the maintenance staff DB 37 and detects the moving means of each maintenance staff on the dispatch target list (step S13). The moving means is, for example, an automobile, a motorcycle, a train, a bicycle, a walk, etc., and the maintenance means DB 37 registers in advance what kind of moving means each maintenance person is acting on.

  Here, if the traffic situation is not considered, a car or a motorcycle is convenient as a means of transportation, and can arrive at the scene quickly from anywhere. However, when the road is congested or closed due to an accident or the like, it takes time. Even if it is a train, for example, if there is a problem in driving due to some cause such as an earthquake, it takes time to wait for arrival.

  Therefore, the maintenance management device 32 obtains the traffic conditions of the road and the railroad from the external information transmission source 23 (step S14), and predicts the arrival time of each maintenance staff in consideration of the traffic conditions at that time ( Step S15).

  Specifically, first, using the GPS information transmitted from the terminal device 20, the current position of each maintenance staff is detected, and the position of the site is specified by the property DB 35. If the maintenance means is an automobile, the time required to arrive at the site is predicted based on the traffic situation of the road from the current position to the site. In the case of a motorcycle, since it can move more smoothly than an automobile, it is predicted that it will arrive, for example, about 1/5 earlier than the arrival time at the automobile.

  In the case of a train, the arrival time is predicted by adding the walking time to the station and the walking time to the site to the travel time from the station near the current location of the maintenance staff to the station near the site. At that time, the traffic situation of the railway is acquired, and if the vehicle is driven later than usual due to, for example, an earthquake, the prediction is made in consideration of the delay time.

  In the case of a bicycle or on foot, the average travel time from the current position to the site is predicted as the arrival time. At that time, for example, if there is a road closed due to an earthquake or the like, the arrival time is predicted by a route avoiding the road.

  In this way, when the arrival time of each maintenance staff is predicted, the maintenance management device 32 selects the necessary number of workers in order from the maintenance staff that can arrive at the site earliest (step S16). A dispatch request is made (step S17).

  In this case, as shown in FIG. 9, it is assumed that the terminal device 20 possessed by the corresponding maintenance staff 19 transmits information such as the name of the property where the abnormality has occurred and the failure status thereof, and requests the dispatch. In addition to these pieces of information, map information describing the route from the current position of the maintenance staff 19 to the site and the traffic situation of the route may be included.

  If there is a response from the maintenance staff who requested the dispatch (Yes in step S18), the dispatching process is terminated here. Further, when there is no response from the maintenance staff or when there is a notification that dispatch is impossible (No in step S18), it is assumed that another maintenance staff is selected by changing the conditions (step S19). The selection based on the condition change is, for example, selecting a maintenance person who takes a little time to the site as a candidate. It is also possible to reduce the number of people dispatched.

  In this way, when any abnormality occurs, the maintenance work that can arrive at the site first is given priority in consideration of traffic conditions, so that the restoration work at the site can be performed smoothly. It is possible to restore the normal operation state quickly.

  The dispatch target list created by the monitoring center 18 is also transferred to the branch offices 21a, 21b, 21c. This is because, for example, when the communication network 22 between the monitoring center 18 and the branch offices 21a, 21b, 21c,... Is disconnected due to a large-scale disaster such as an earthquake, the measures for the failed property can be switched to the branch office. It is to keep. In this case, each branch store 21a, 21b, 21c... Takes over the subsequent work based on the history information immediately before cutting stored in the monitoring center history unit 48.

  In addition, the branch office stores 21a, 21b, 21c,... Update the property information and the maintenance personnel information, respectively. The updated information is transmitted to the monitoring center 18 via the communication network 22. This prevents the information from becoming obsolete.

  In the above-described embodiment, the maintenance staff skills are divided into five levels. However, the maintenance staff skills may be divided and managed more finely.

  In addition, the moving means of maintenance personnel may be managed more finely and the arrival time for each may be predicted.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various forms can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be omitted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
