Description

  The present invention relates to an elevator maintenance management system that manages the movement of maintenance personnel who perform maintenance and inspection of elevators such as elevators and escalators.

  The elevators of each property are connected to a monitoring center via a communication network. A number of operators are in service at the monitoring center. Each operator remotely monitors the operation state of the elevator of each property through a screen of a terminal device called a monitoring console, and manages the movement of maintenance personnel who perform maintenance and inspection of these elevators.

Here, for example, there is Patent Literature 1 as a system for managing the movement of maintenance personnel. This Patent Document 1 discloses that when any abnormality occurs, the position of a maintenance worker is detected using a GPS (global positioning system), and the detected position is displayed on a monitor screen.
JP-A-2005-272101

  The GPS described above is a system that receives radio waves transmitted from a plurality of artificial satellites launched in low earth orbit and measures the longitude and latitude and altitude of the current position. The current position is accurate to several meters to several tens of meters. Can be accurately identified. On the other hand, however, there is a drawback in that it is difficult to detect GPS radio waves in buildings and underpasses, so that accurate positions cannot be detected.

  Therefore, when GPS is used as in Patent Document 1, the current position can be displayed when a maintenance worker is moving with a vehicle or the like, but when entering a building, the position where radio waves can be received immediately before that is displayed. It can only be displayed as a position. For this reason, there is an error between the actual position, and when any abnormality occurs, there is a problem that the position of the maintenance staff is wrong on the monitoring side, and the response is delayed.

  The present invention has been made in view of the above points, and provides a maintenance management system for an elevator capable of accurately grasping the position of each property on the map and the position of the maintenance staff present in the vicinity thereof. With the goal.

The elevator maintenance management system according to the present invention is an elevator maintenance management system that manages the movements of maintenance personnel who maintain and inspect properties scattered in each area. A map database storing regional map information, a database search means for searching a map of a specified area from the property database, and searching a position of the property existing in the specified area from the property database, and the database search means A map display means for displaying the mark on the specified terminal device with a mark on the obtained map of the designated area, a position detecting means for detecting the position of the maintenance staff, and the maintenance staff When the maintenance inspection work is started, the position detected by the position detecting means is based on the position of each property. A positive position correcting means, on a map displayed by said map display means, along with the previous maintenance work start of the maintenance personnel to view the maintenance personnel mark detected position by said position detecting means, the maintenance personnel When the maintenance check work is started and the position is corrected by the position correcting means, the display processing means for moving the maintenance staff mark to the corrected position is provided.

  According to the present invention, it is possible to accurately grasp the position of each maintenance person existing in the vicinity of the position of each property on the map. As a result, when any abnormality occurs, it is possible to dispatch a maintenance staff nearby to respond quickly.

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

  FIG. 1 is a diagram showing a configuration of a maintenance management system when an elevator is taken as an example of an elevator according to an embodiment of the present invention. 11a, 11b, 11c... In the figure indicate customer properties (buildings). These properties 11a, 11b, 11c... Have elevators (EL) 12a, 12b, 12c. The number of elevators installed varies depending on the property. That is, a property where only one elevator is installed and a property where many elevators are not installed are mixed.

  The elevators 12a, 12b, 12c... Are connected to the monitoring center 14 via a communication network 13 such as a public line. The monitoring center 14 receives signals issued from the elevators 12a, 12b, 12c,... And constantly monitors their operation states.

  Here, FIG. 2 shows the configuration of the elevator 12a as a representative.

  The elevator 12a includes a hoisting machine 21, a rope 22 wound around the hoisting machine 21, a car 23 attached to one end of the rope 22, and a counterweight 24 attached to the other end. . The hoisting machine 21 is installed in the machine room of the property (building) 11a. By the rotational drive of the hoisting machine 21, the car 23 and the counterweight 24 move in a hoistway manner through the rope 22.

  The control device 25 includes a computer equipped with a CPU, ROM, RAM, and the like, and controls the entire elevator including drive control of the hoisting machine 21 and the like. The control device 25 has a communication function, and transmits and receives data to and from the monitoring center 14 via the communication network 13.

  Next, the configuration of the monitoring center 14 in this embodiment will be described in detail.

  FIG. 3 is a block diagram showing the configuration of the monitoring center 14.

  In the monitoring center 14, a server 31 and PCs (Personal Computers) 32a, 32b, 32c... Are installed.

  The server 31 exists as a control device for the monitoring center 14. The PCs 32a, 32b, 32c... Are connected to the server 31 via a communication line 33 such as a LAN (Local Area Network). These PCs 32a, 32b, 32c... Are terminal devices used by each operator as a monitoring console, and have various functions.

  FIG. 4 is a block diagram showing the configuration of the server 31 installed in the monitoring center 14.

  The server 31 includes a control unit 41, a storage unit 42, various databases 43, a communication unit 44, and an interface (I / F) 45.

  The control unit 41 includes a CPU, and executes various processes by reading the program 42a stored in the storage unit 42. In addition, the control unit 41 includes a database search unit 41a, a map display unit 41b, an identification display unit 41c, a display processing unit 41d, a maintenance staff detection unit 41e, and a position correction unit 41f as functional units for realizing the present system. Is provided.

  The database search unit 41a searches for a map of the designated area from the article database 43a included in the various databases 43, and searches the map database 43c for the positions of the articles 11a, 11b, 11c. The map display unit 41b attaches a property mark on the map of the designated place castle obtained by the database search unit 41a and displays it on the PCs 32a, 32b, 32c.

  The identification display part 41c identifies and displays the property mark based on signals issued from the elevators 12a, 12b, 12c... Of the properties 11a, 11b, 11c. Specifically, the state of each elevator is determined for each property, and the property mark on the map is identified and displayed in colors (“red”, “yellow”, “blue”) according to the state.

  When an arbitrary property mark is selected on the map displayed by the map display unit 41b, the display processing unit 41d changes the display range so that the selected property mark is substantially at the center of the screen. At that time, the maintenance staff mark is displayed at the position detected by the maintenance staff detection unit 41e, and when the position correction is performed by the position correction section 41f, the maintenance staff mark is moved to the corrected position.

  The maintenance staff detection unit 41e detects the position of the maintenance staff using GPS. The position correction unit 41f corrects the position detected by the maintenance staff detection unit 41e with reference to the position of each property.

  The storage unit 42 includes a memory such as a ROM and a RAM, and stores various data necessary for the processing of the control unit 41 in addition to the program 42a. In addition, the storage unit 42 is provided with an identification display table 42b for identifying and displaying the property mark according to the state of the elevator of each property.

  Now, as the state of the elevator, some sort of abnormality has occurred, indicating that the elevator operation has been hindered. “Control”, which indicates that the elevator has some control operation and has landed on the nearest floor. Assume three patterns of “return” indicating a state in which the operation is recovered. In the identification display table 42b, the property mark is set to be identified and displayed in “red” in the “occurrence” state, “yellow” in the “control”, and “blue” in the “return”. ing.

  Furthermore, the storage unit 42 is provided with a dispatch rule table 42c that stores rules for automatically dispatching maintenance personnel to the property where the abnormality has occurred.

  On the other hand, the various databases 43 provided in the server 31 include a property database (property DB) 43a, a maintenance worker database (maintenance worker DB) 43b, a map database (map DB) 43c, and the like. Note that these databases 43a to 43c are actually provided in the storage unit 42 and the like.

  The property database 43a stores information on each property 11a, 11b, 11c. Specifically, as shown in FIG. 5, the identification number (property ID) of each property, the property name, the address, the number of elevators installed in the property, information on the number, etc. are stored.

  The maintenance staff database 43b stores information on each maintenance staff. Specifically, as shown in FIG. 6, each maintenance person's identification number (maintenance person ID), name, affiliation, and information on the portable terminal possessed by the maintenance person (terminal ID, address, telephone number, etc.) The current position of maintenance personnel, attribute information, status information, and the like are stored.

  The “current position” is detected using GPS as will be described later, and is corrected by a signal transmitted from the portable terminal when the maintenance staff enters and exits the site.

  Further, the “attribute information” includes the type of maintenance personnel. The job categories are broadly classified into “inspectors” who mainly perform general periodic inspections and “statutory inspectors” who have legal inspection qualifications. Legal inspectors can also serve as inspectors, but the number is generally smaller than inspectors. “Status information” is information indicating the work status of the maintenance personnel, and “working” or “moving” is recorded.

  The map database 43c stores map information (image information) of each region. Specifically, as shown in FIG. 7, a plurality of map information is classified and stored according to the scale ratio. In this case, the higher the scale ratio of the map, the wider the area, and the lower the scale ratio, the narrower the area.

  Moreover, the communication part 44 provided in the server 31 transmits / receives data via the communication network 13 between the elevators 12a, 12b, 12c... Installed in the respective properties 11a, 11b, 11c. The interface 45 performs data input / output processing with the PCs 32a, 32b, 32c... Connected to the server 31.

  FIG. 8 is a block diagram showing the configuration of the operator's PC 32 a installed in the monitoring center 18. The other PCs 32b, 32c,... Have the same configuration.

  The PC 32 a includes a control unit 51, a storage unit 52, an interface (I / F) 53, an input unit 54, and a display unit 55.

  The control unit 51 includes a CPU, and executes various processes by reading a program 52a stored in the storage unit 52. The storage unit 52 includes a memory such as a ROM and a RAM, and stores various data necessary for the processing of the control unit 51 in addition to the program 52a. The interface 53 performs data input / output processing with the server 31.

  The input unit 54 includes an input device such as a keyboard and a mouse, and is used when an operator performs an input operation of data or a command or a selection operation on a screen. The display unit 55 includes a display device such as a CRT (Cathode-ray tube) or an LCD (Liquid Crystal Display), and displays various data.

  Next, the operation of this system will be described.

  FIG. 9 is a flowchart showing the flow of remote monitoring processing executed by the server 31 in the monitoring center 14. Note that the processing shown in this flowchart is executed when the control unit 41 provided in the server 31 reads the program 42 a stored in the storage unit 42.

  Assume that the operator of the monitoring center 14 operates the PC 32a to display a map of a certain area.

  When there is a map display request from the PC 32a, the server 31 first searches the map database 43c for a map of the area designated by the operator through a predetermined operation (step S11), and determines the position of the article existing in the designated area. Search from the database 43a (step S12).

  When there is a corresponding property, the server 31 attaches a property mark on the map read from the map database 43c based on the location information (address) of the property, and displays the operator's PC 32a (specifically, the display of the PC 32a). Part 55) (step S13).

  FIG. 10 shows an example of the map display screen 61 displayed on the operator's PC 32a.

  62 in the figure is a map of the designated area. 63a to 63g are property marks, and 64 is a scaler. 65 is a property mark explanation column, 66 is a maintenance staff mark explanation column, and 67 is a scale ratio display section. At the time of activation, a map with a predetermined scale ratio is displayed. By sliding the scaler 64, the scale of the map can be arbitrarily changed.

  In this map display screen 61, rectangular parallelepiped-shaped property marks 63a to 63g are displayed at a predetermined size at the position of each property on the map 62. The property marks 63a to 63g represent the position of the property to be monitored and the state of the elevator.

  When any signal is issued from the elevator of each property, the server 31 determines the current state from the signal, refers to the identification display table 42b, and refers to the property marks 63a to 63b in colors according to the state at that time. 63g is identified and displayed (step S14).

  Specifically, when an elevator abnormality signal is issued, the property mark 63a is identified and displayed in “red” indicating the “occurrence” state. When the control signal is issued, the property mark 63d is identified and displayed with “yellow” indicating the “control” state, and when the elevator operation return signal is issued, the “return” state is indicated. The property mark 63e is identified and displayed in “blue”.

  The abnormal signal / control signal is automatically issued from the control device 25 shown in FIG. 2 when an abnormality occurs in the elevator. When the operation of the elevator is restored, the operation return signal is automatically issued from the control device 25 shown in FIG.

  In addition, one mark is displayed for each property, and the property mark is identified and displayed in accordance with the state of highest importance among the properties where a plurality of elevators are installed. Here, “occurrence” is the most important state, followed by “control” and “return”.

  Further, the colorless property marks 63b, 63c, 63g, and 63f indicate that elevators installed in these properties are in a normal state.

  When the operator selects an arbitrary property mark 63a on the map 62 by clicking (Yes in step S15), the server 31 displays the map 62 so that the selected property mark 63a is substantially at the center of the screen. The range is changed (step S16).

  The state at this time is shown in FIG. In this example, the state when the scale ratio is further changed is shown. In the map 62 after the display range is changed, the property mark 63a selected by the operator is displayed at the center position of the screen. Therefore, when looking at the center of the screen, the location of the property can be confirmed at a glance, even if the terrain is complicated.

  Further, in accordance with the selection operation of the property mark 63a, the server 31 detects maintenance personnel around the property mark 63a (step S17). Specifically, the presence / absence of maintenance personnel is detected within the range of the currently displayed map 62 with reference to the position of the property indicated by the property mark 63a. If there is a corresponding maintenance person, the server 31 reads the attribute information of the maintenance person from the maintenance person database 43b of FIG. 6, and based on the attribute information, the position of the maintenance person is displayed on the map 62 in a specific display form. It is displayed (step S18).

  The position of the maintenance staff is detected using GPS as will be described later. As a form for displaying the position of the maintenance staff on the map, maintenance staff marks 68a and 68b as shown in FIG. 11 are used. The maintenance staff marks 68a and 68b are provided with symbols (points) and (laws) indicating the type of maintenance staff based on the attribute information described above. (Point) refers to an inspector, and (Law) indicates a legal inspector.

  In this way, the position of maintenance personnel near the property and the type of job are displayed, so when any abnormality occurs, the most appropriate maintenance personnel are selected and dispatched to the site in consideration of the distance to the property and the type of job. can do. In this case, when the operator selects an arbitrary maintenance staff mark on the screen, information regarding the contact information of the corresponding maintenance staff is displayed in a link. The operator can issue a dispatch command to the maintenance staff by looking at the contact information.

It is also possible to automate the dispatch of maintenance personnel at this time.
This is because the server 31 refers to the dispatch rule table 42c provided in the storage unit 42, selects an appropriate maintenance staff from among the maintenance staff near the property, and carries the maintenance staff's mobile phone. For example, it can be realized by transmitting a message such as “An anomaly has occurred in the XX property. Please go to the site immediately” to the terminal (see the mobile terminal 16 in FIG. 13).

  For example, the following rules are stored in the dispatch rule table 42c.

  ・ If there are “inspectors” and “statutory inspectors” near the failure site, the “inspectors” will be dispatched with priority. This is because “statutory inspectors” have advanced technical knowledge and a small number of people, so if normal abnormalities occur, dispatch “inspectors” as much as possible to handle properties that require legal inspection. Because I want to prepare.

  ・ If there are many "inspectors" near the failure site, dispatch the maintenance personnel closest to the site among them.

  ・ If there are only “statutory inspectors” near the breakdown site, dispatch the maintenance personnel closest to the site among them.

  ・ If the property requires legal inspection, a “statutory inspector” will be dispatched.

  In addition, when the operator confirms the position of the site by sliding the scaler 64 provided on the map display screen 61 and instructing the change of the scale ratio, the server 31 displays the map at the scale ratio instructed at that time. 62 is displayed.

  Specifically, as shown in FIG. 7, map information corresponding to the instructed scale is read from the map database 43c and displayed on the PC 32a of the operator. At that time, the server 31 displays the map 62 after changing the scale ratio with the property mark 63a as the center of the screen.

  Note that the property marks 63a to 63g and the maintenance staff marks 68a and 68b added on the map are always displayed at the same size regardless of the change in the scale ratio.

  Here, on the map display screen of FIG. 11, the position of the maintenance staff is detected using GPS, and maintenance staff marks 68a and 68b are displayed at the detected positions. However, since GPS radio waves do not easily reach the building, if the maintenance staff enters the building for inspection work, the accurate position cannot be detected. Therefore, in the present embodiment, the position detected by the GPS is corrected using a specific signal transmitted when the maintenance person enters the building.

  Hereinafter, the position correction method according to the present embodiment will be described in detail with reference to FIGS.

  FIG. 13 is a diagram for explaining the functions of the mobile terminal possessed by the maintenance staff. FIG. 14 is a diagram showing an example of a code table, and FIG. 15 is a diagram showing a configuration in an elevator car. FIG. 16 is a diagram illustrating an example of a property menu displayed on the display unit of the mobile terminal.

  As shown in FIG. 13, the maintenance staff 15 has a portable terminal 16 with a communication function. The mobile terminal 16 is composed of a mobile phone, for example, and has various functions necessary for maintenance and inspection work in addition to a communication function with the monitoring center 14. In the figure, 16a is a display unit of the mobile terminal 16, 16b is an operation unit of the mobile terminal 16, and has various operation buttons. Reference numeral 16c denotes an imaging unit 16c, which is used here when reading a two-dimensional management code recorded in the code table 76 shown in FIG.

  The portable terminal 16 has a GPS reception function, and receives a GPS signal radio wave transmitted from the artificial hygiene 17 to detect the current position. In practice, by receiving radio waves of GPS signals from at least four artificial sanitations 17, it is possible to detect with high accuracy including latitude, lightness, altitude, and time.

  Such a position detection function using GPS can be provided on the mobile terminal 16 side, but in general, it is provided on the monitoring center 14 side in order to reduce the processing load on the mobile terminal 16. Yes. In this case, the GPS signal received by the mobile terminal 16 is periodically sent to the server 31 in the monitoring center 14, and the server 31 performs position detection processing based on the GPS signal.

  Information (identification number, telephone number, e-mail address, etc.) related to the portable terminal 16 is registered in advance in the maintenance person database 43b provided in the server 31 in the monitoring center 14 together with the information of the maintenance person 15 who is the owner. (See FIG. 6).

  On the other hand, a code table 76 as shown in FIG. 14 is provided in the form of a sticker sheet at a predetermined place of the elevator of each property. In this code table 76, information (for example, property ID, building address, machine type, etc.) necessary for the maintenance and inspection of the property is recorded as a two-dimensional management code including a QR code (registered trademark).

  FIG. 15 shows an example in which a code table 76 is provided in the car 23. Reference numeral 70 in the figure denotes a car door, which engages with a landing door (not shown) when the car 23 arrives and opens and closes. An operation panel 71 is installed next to the car door 70. On the operation panel 71, a destination button 72 for each floor, a door opening button 73 for instructing door opening, a door closing button 74 for instructing door closing, and the like are arranged.

  On the operation panel 71, an emergency call telephone 75 is installed. The telephone 75 has an emergency call button 75a, and a telephone line is automatically connected to the monitoring center 14 by pressing the emergency call button 75a. The code table 76 described above is pasted near the operation panel 71.

  Here, when the maintenance staff 15 arrives at the site and starts the maintenance inspection work, when the two-dimensional management code recorded in the code table 76 is read through the photographing unit 16c of the portable terminal 16, the management code is decoded. And a signal including the identification number (property ID) of the property is transmitted to the monitoring center 14. At this time, an identification number (terminal ID) unique to the portable terminal 16 is automatically added to the signal and sent to the monitoring center 14.

  As shown in the flowchart of FIG. 9, when the server 31 in the monitoring center 14 receives a signal transmitted from the portable terminal 16 of the maintenance staff 15 (Yes in step S19), first, the terminal ID added to the signal The maintenance staff database 43b is searched based on the above, and the source maintenance staff 15 is specified (step S20).

  Next, the server 31 corrects the position of the maintenance staff 15 currently displayed on the map to the position of the property by searching for the address of the property from the property database 43a based on the property ID included in the signal. (Step S21). At this time, the server 31 updates the “current position” in the maintenance staff database 43b of FIG. 6 based on the corrected position, and sets “working” in the “status information”.

FIG. 12 shows the corrected map display screen.
In this example, the maintenance worker mark 68a shown in FIG. 11 is moved to the position of the property mark 63a. The maintenance staff mark 68a may be displayed over the property mark 63a or may be displayed near the property mark 63a.

  Further, when the maintenance staff 15 finishes the work, if the management code in the code table 76 is read again using the portable terminal 16, a similar signal is transmitted to the server 31. When the server 31 receives the second signal from the same site, the server 31 considers that the work has been completed and updates the “status information” in the maintenance staff database 43b to “moving”. While the maintenance staff 15 is moving, the position is detected by the GPS as described above, and the maintenance staff mark 68a is sequentially displayed according to the detected position.

  Thus, even if the maintenance staff 15 enters the building and cannot receive GPS radio waves for a long time, if the building is an elevator property, the maintenance code 15 is transmitted from the portable terminal 16 by reading the management code. Based on the signal, the current position of the maintenance staff 15 can be corrected and accurately displayed on the map.

  Here, if the subject of position detection is a general person, there is no particular problem even if the position detected before entering the building is displayed, but in the case of the maintenance staff 15 engaged in elevator work It is necessary to always know the current position accurately in preparation for an emergency such as an earthquake. Therefore, even when the maintenance staff 15 is working in the building for a long time, it is very important to be able to accurately display the position there.

  In the above embodiment, the code table 76 is provided in the elevator car 23. However, the code table 76 is not limited to the inside of the car 23, and may be, for example, near an operation panel installed at a landing. In short, any place where the maintenance code 15 can easily read the management code when entering the building and starting the work may be used.

(Modification 1)
In the above embodiment, the management code is read to notify the monitoring center 14 that the maintenance staff 15 is in the building. However, as another method, the emergency call telephone 75 installed in the car 23 is used. May be used.

  As shown in FIG. 15, the telephone 75 has an emergency call button 75a, and the telephone line is automatically connected to the monitoring center 14 by pressing the emergency call button 75a. Therefore, when the maintenance staff 15 enters the building, if the emergency call telephone 75 is operated, the server 31 side in the monitoring center 14 specifies the position of the property from the signal transmitted at that time. The position of the property can be displayed on the map as the current position of the maintenance staff 15.

  In this way, if an emergency call is used, maintenance personnel 15 must be in the building even if the mobile terminal 16 cannot be used, such as when radio reception in the building is poor or the communication line is abnormal. Can be notified to the monitoring center 14, and the current position of the maintenance staff 15 can be accurately displayed on the map.

(Modification 2)
Alternatively, the operation center 16b of the portable terminal 16 owned by the maintenance staff 15 may be operated to notify the monitoring center 14 that the building has entered the building. In this case, if the code number of the property is transmitted from the mobile terminal 16, the server 31 side can specify the position of the property from the code number, and displays the property position on the map as the current position of the maintenance staff 15. be able to.

  Thus, if it is the method of notifying by operation of the portable terminal 16, a present position can be notified, without requiring a management code.

(Modification 3)
In addition, as shown in FIG. 16, a property menu describing the position of each property to be inspected for maintenance is displayed on the display unit 16a of the portable terminal 16 of the maintenance staff 15. When the maintenance staff 15 selects the current property on the property menu, the code number of the property is automatically distributed to the server 31 of the monitoring center 14, and the server 31 side can specify the position of the property from the code number, The position of the property can be displayed on the map as the current position of the maintenance staff 15.

  As described above, the method using the property menu has an advantage that the current position can be easily notified without imposing a burden on the maintenance staff 15.

  In the above-described embodiment, identification is performed by changing the display colors of the property marks 63a to 63g. However, for example, identification may be performed by changing the shape of the mark.

  Moreover, the shape of the property marks 63a to 63g is not limited to a rectangular parallelepiped, and may be, for example, a rectangle or a circle, and may be any shape as long as it is not confused with other symbols on the map. good.

  The same applies to the maintenance staff marks 68a and 68b. The present invention is not limited to the above-described embodiment, and the shape may be changed according to the job type or the color may be changed.

  In the above embodiment, the maintenance worker's job type is classified and displayed in two types, but it may be further displayed by being divided into job types.

  Moreover, although the server 31 in the monitoring center 14 performs the series of processes related to the map display described above, the PCs 32a, 32b, 32c,.

  In the above-described embodiment, an elevator is described as an example of a monitoring target. However, the present invention can be similarly applied to remote monitoring of other elevators such as an escalator.

  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.
