In the example of FIG. 5, the importance level is set to three levels L3 to L1. “Level L3” has the highest importance, followed by “Level L2” and “Level L1”. In addition, display colors such as “red” for “level L3”, “yellow” for “level L2”, and “blue” for “level L1” are set as the property mark identification display.

・ "Level L3"
The most important “level L3” is a state where the elevator does not move or the elevator should not move. As a signal corresponding to the “level L3”, a signal related to an accident that requires a maintenance worker to be dispatched is set. Specifically, there are a confinement signal, a start disable signal, a power failure signal, and the like.

  The confinement signal is a signal indicating that the user is confined in the car 23. The start impossible signal is a signal indicating that the elevator is completely stopped and cannot be started. The power failure signal is a signal indicating that the lighting device in the car 23 has a power failure.

The rope elongation detection signal is a signal indicating that the tension of the rope 22 supporting the car 23 has decreased.

・ "Level L1"
“Level L1” having the lowest importance is a state in which the operation of the elevator has been restored. As a signal corresponding to the “level L1”, a signal related to the restoration of the entire failure is set. Specifically, there are a start return signal, a power failure return signal, a seismic control operation completion signal, and the like.

  The activation return signal is a signal indicating that the operation of the elevator has been restored. The power failure recovery signal is a signal indicating that the power failure of the lighting device in the car 23 has been recovered. The seismic control operation completion signal is a signal indicating that the car 23 has been normally moved to the nearest floor by the seismic control operation.

  The signals of the levels L3 to L1 described above are output from the control devices 25 of the elevators 12a, 12b, 12c,... Installed in the properties 11a, 11b, 11c, and the server 31 of the monitoring center 14 via the communication network 13. Given to.

  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. 6, 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 of units, and the like are stored.

  The maintenance staff database 43b stores information on each maintenance staff. Specifically, as shown in FIG. 7, the identification number (maintenance personnel ID), name, affiliation, information of terminal devices (such as mobile phones) possessed by the maintenance personnel, and the area in charge, as shown in FIG. The information is stored.

  The map database 43c stores map information (image information) of each region. Specifically, as shown in FIG. 8, a plurality of pieces of map information are 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.

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. 10 is a flowchart showing the flow of map display 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 section of the PC 32a). 55) (step S13).

FIG. 11 shows an example of a map display screen 61 displayed on the operator's PC 32a.
62 in the figure is a map of the designated area. 63a to 63e are property marks, 64 is a scaler, and 65 is a property mark description column. Reference numeral 66 denotes a scale ratio display unit. 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 63e are displayed at predetermined positions on the map 62. These property marks 63a to 63e represent the position of the property to be monitored and the state of the elevator. In addition, about the property in which several elevators were installed, the property mark for the number of units is displayed in piles.

  Here, it is assumed that a signal indicating an operation state is issued from an elevator installed in each property. When the signal is received by the communication unit 44 (step S14), the server 31 refers to the importance level table 42b provided in the storage unit 42 and determines the importance level for the signal (step S15).

  In this case, as shown in FIG. 5, if the signal issued from the elevator is a confinement signal, a start disable signal, a power failure signal, or the like, it is determined that “level L3” has the highest importance. Further, if the ventilation fan abnormality signal, the seismic control operation signal, the door repetition signal, the terminal system abnormality signal, the rope extension detection signal, or the like, it is determined that the level of importance is “level L2”. If it is a start return signal, a power failure return signal, a seismic control operation completion signal, etc., it is determined that the level of importance is the lowest “level L1”.

  When the importance of the signal is determined in this way, the server 31 identifies and displays the property marks 63a to 63e on the map 62 based on the determination result (step S16). Specifically, referring to the display color information set in the importance level table 42b, the “level L3” signal is “red”, the “level L2” signal is “yellow”, and the “level L1” signal. Displays the property marks 63a to 63e in different colors according to the importance of the signal, such as “blue”.

  At that time, for a property having a plurality of elevators (Yes in step S17), the property mark is identified and displayed by giving priority to the signal having the highest importance (step S18). Specifically, the color of the signal level with the highest importance is displayed at the top of the mark as the representative color of the property.

  For example, if there is a property with two elevators, and one of the signals is “level L3” and the other one is “level L2,” “red” indicating “level L3” "Is displayed as the representative color at the top of the property mark (see property mark 63b in FIG. 11).

  If one of the two elevators is “level L2” and the other one is “level L1”, “yellow” indicating “level L2” is used as a representative color. It is displayed at the top of the property mark (see property mark 63c in FIG. 11).

  By such identification display of the property marks 63a to 63e, it is possible not only to confirm the position of each property on the map, but also to grasp the importance at a glance when a certain signal is issued. As a result, when an earthquake or the like occurs, the state of each property existing in the area can be grasped, and a response such as dispatching maintenance personnel to a property of “Level L3” can be performed quickly. .

  Further, when a plurality of elevators are installed in one property, the state of the elevator that emits the signal having the highest importance among them is preferentially displayed. Therefore, even if there are multiple properties on the map and only one property mark can be visually recognized for each property, it is possible to deal appropriately without missing the fact that each property is abnormal. it can.

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

  Moreover, the shape of the property marks 63a to 63e 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.

  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,.

  Further, for example, a terminal device owned by a maintenance staff may be equipped with a GPS (global positioning system) reception function, and the server 31 may receive position information transmitted from the terminal device. With such a configuration, the position of the maintenance staff can be displayed on the map screen in real time. Furthermore, when an abnormality occurs, maintenance personnel near the corresponding property are automatically detected, and a dispatch command is issued to a terminal device (such as a mobile phone) possessed by the maintenance personnel with reference to the maintenance personnel database 43b. Etc. are also possible.

  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.
